Description

Technical Field

[0001] The present application relates to the technical field of test block curing, and in particular to a lifting type curing box and a cement stone test system. Background Art

[0002] In the field of building materials, the maintenance of test blocks is crucial to ensuring the quality of the project. The maintenance of test blocks needs to be carried out in a specific temperature and humidity environment to simulate the conditions of use in actual projects, so as to accurately evaluate key indicators such as the strength and durability of the materials.

[0003] At present, most of the common test block curing boxes on the market adopt a drawer-type, horizontal push-pull opening and closing structure design. This drawer-type structure has some disadvantages. On the one hand, the horizontal push-pull method requires a large horizontal space to be implemented during the operation, which may cause inconvenience in space utilization for laboratories or construction sites with limited space. On the other hand, the drawer-type structure is often difficult to achieve a high standard in terms of sealing performance. During the curing process of the test block, problems such as water evaporation and the entry of external impurities are prone to occur, which in turn affects the stability of the curing environment and the curing quality of the test block.

[0004] In addition, in the existing design of water tanks for curing, the circulating pump is usually installed directly in the main body of the water tank. The circulating pump will generate turbulence when running, which seriously disturbs the water balance in the water tank. The instability of the water body will lead to uneven environmental parameters such as water temperature and water quality around the test block, making it impossible to maintain the test block under consistent conditions, thus affecting the accuracy and reliability of the test block quality detection.

DETAILED DESCRIPTION

[0019] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0020] The present application provides a lifting type curing box, comprising: a water tank 10, for storing water, in which a test block can be immersed for curing; a test block holder 20, arranged in the water tank 10, for loading the test block to be cured; a lifting drive module 30, for driving the test block holder 20 to move in a vertical direction, so as to facilitate the test block holder 20 to enter and exit the water tank 10; a circulating pump, arranged in the water tank 10, for optimizing the water environment; a temperature control module 60, for controlling the water temperature in the water tank 10; wherein, the top of the water tank 10 is open, and the test block holder 20 can enter and exit the water tank 10 through the open top; a cover plate 21 is provided on the top of the test block holder 20, and the cover plate 21 can close the top of the water tank 10.

[0021] For details, please refer to Figure 1 and Figure 2 In the illustrated embodiment, the curing box further includes a housing 40, and the water tank 10, the lifting drive module 30 and the temperature control module 60 are all arranged in the housing 40. The housing 40, as the external protection structure of the curing box, is usually made of a strong and durable material, such as metal (stainless steel, etc.) or high-strength engineering plastic; it has a certain strength and rigidity, and can protect the internal water tank 10 and other components from external physical damage, dust and moisture intrusion.

[0022] Combined with reference Figure 3 A mounting frame 42 is provided in the housing 40, and a temperature control module 60 is fixedly arranged on the mounting frame 42. The temperature control module 60 is used to control the water temperature in the water tank 10. It usually includes a temperature sensor, a controller, and a heating or cooling device. The temperature sensor is used to monitor the water temperature in the water tank 10 in real time and feed the data back to the controller. The controller can start the heating device for heating when the water temperature is lower than the set value according to the preset temperature range; when the water temperature is higher than the set value, the cooling device is started for cooling, so that the water temperature is always kept within an appropriate range, ensuring that the test block can be maintained in a stable temperature environment.

[0023] Optionally, the temperature control module 60 adopts a compressor constant temperature system. The compressor constant temperature system is based on the reverse Carnot cycle principle, and is mainly composed of four key components: a compressor, a condenser, a throttling device (such as an expansion valve), and an evaporator; its basic principle is to compress the refrigerant (such as Freon, etc.) through a compressor to make it a high-temperature and high-pressure gas. The high-temperature and high-pressure refrigerant gas enters the condenser, where the refrigerant releases heat to the surrounding environment (usually air or cooling water), cools itself and liquefies into a high-pressure liquid. When the high-pressure liquid passes through the throttling device, the pressure suddenly decreases and becomes a low-temperature and low-pressure liquid and gas mixture. The low-temperature and low-pressure refrigerant enters the evaporator, absorbs the heat of the water in the water tank 10 in the evaporator, and reduces the temperature of the water, while the refrigerant itself evaporates and becomes a low-temperature and low-pressure gas, which is sucked into the compressor again for compression, and this cycle is repeated to achieve the control of the water temperature in the water tank 10.

[0024] In a specific embodiment, the maintenance water temperature is required to be maintained at 20±0.5℃. When the temperature sensor detects that the water temperature in the water tank 10 is higher than the set temperature, the controller starts the compressor. The compressor starts working, compressing the low-temperature and low-pressure refrigerant gas into a high-temperature and high-pressure gas, and then sending it to the condenser. In the condenser, the refrigerant dissipates heat to the surrounding environment through heat sinks and the like, and cools itself to liquefy. The liquefied high-pressure refrigerant passes through the throttling device, the pressure is reduced, and the temperature is also reduced, and then enters the evaporator. In the evaporator, the low-temperature and low-pressure refrigerant absorbs the heat of the water in the water tank 10, causing the water temperature to drop. The refrigerant after absorbing heat evaporates into gas and is sucked into the compressor again, completing a refrigeration cycle.

[0025] When the temperature sensor detects that the water temperature in the water tank 10 is lower than the set temperature, the controller will take corresponding measures. For some compressor thermostatic systems with heating functions (such as heat pump types), the original evaporator can be changed into a condenser and the original condenser can be changed into an evaporator by changing the flow direction of the refrigerant (for example, using a four-way valve). At this time, the high-temperature and high-pressure refrigerant gas compressed by the compressor enters the original evaporator (now used as a condenser), releasing heat to the water in the water tank 10, raising the water temperature. The original condenser (now used as an evaporator) absorbs heat from the surrounding environment. If it is a simple refrigeration type compressor thermostatic system, it can be equipped with an auxiliary electric heating device. When the water temperature is too low, the electric heating device is started to increase the water temperature.

[0026] During the whole process, the temperature sensor will continuously monitor the water temperature in the water tank 10 and feed back the real-time temperature data to the controller. The controller can compare the actual water temperature with the set temperature according to the set temperature range to determine whether to start cooling, heating or maintain the current state. When the water temperature is within the set temperature range, the controller will adjust the working state of the compressor or turn off the auxiliary electric heating device to maintain the stability of the water temperature.

[0027] The compressor thermostatic system can control the water temperature more accurately and keep the water temperature fluctuation within a smaller range (±0.5°C), meeting the strict requirements of the test block maintenance on temperature stability. A stable temperature environment helps to ensure the maintenance quality of the test block. As the core component of the temperature control module 60, the compressor can quickly and effectively compress the refrigerant to achieve cooling and heating functions. Compared with other temperature control methods, such as simple electric heating or natural cooling, the compressor thermostatic system is more efficient in regulating water temperature.

[0028] Continue to refer to Figure 3 A group of load-bearing brackets 43 are provided in the outer shell 40. The load-bearing brackets 43 are made of I-shaped steel. The load-bearing brackets 43 are arranged in a symmetrical form. The temperature control module 60 is arranged between the load-bearing brackets 43 and the mounting frame plate 42. The water tank 10 and the lifting drive module 30 are arranged on the load-bearing brackets 43.

[0029] The I-shaped steel has a unique cross-sectional shape, with wide and thick flanges and a certain thickness of the web. This structure enables the I-shaped steel to exhibit high strength and load-bearing capacity when subjected to vertical pressure and horizontal bending moment. For the curing box, the water tank 10 and the lifting drive module 30 are heavy, and the I-shaped steel can reliably support these weights, ensuring that the load-bearing bracket 43 will not be deformed or damaged during long-term use, thereby ensuring the stability and reliability of the entire curing box.

[0030] In addition, during the operation of the maintenance box, especially when the lifting drive module 30 is working, certain vibrations and impact forces may be generated. Due to the cross-sectional shape of the I-shaped steel, it can evenly distribute stress when subjected to force and is not prone to twisting and deformation. Therefore, the load-bearing bracket 43 can effectively resist the influence of these external forces, maintain the installation position of the equipment unchanged, and ensure that components such as the water tank 10 and the lifting drive module 30 can continue to operate normally.

[0031] Continue to refer to Figure 3 The water tank 10 is located at the center of the load-bearing bracket 43 and directly above the temperature control module 60. The water tank 10 is an important component of the curing box, mainly used to store water and provide the water environment required for the curing of the test block. The water tank 10 is made of water-resistant and corrosion-resistant materials (such as stainless steel, high-strength plastic, etc.), has good water resistance and chemical stability, and can withstand long-term immersion in water and possible corrosion of chemical substances. The top of the water tank 10 is open to facilitate the entry and exit of the test block bracket 20.

[0032] Optionally, a flap is provided on the top of the shell 40. When the test block holder 20 is raised or lowered, the flap can be turned outward and away from the shell 40 by manual operation or automatic drive (such as setting a flap cylinder, etc.), thereby opening the top; during maintenance, the flap can close the top of the shell 40.

[0033] The flip cover design can optimize the maintenance environment control; during the maintenance process, the flip cover closes the outer shell 40, which helps to maintain the stability of the internal environment of the maintenance box. It can effectively reduce the interference of external environmental factors (such as temperature fluctuations, humidity changes, dust, etc.) on the temperature and humidity in the box, thereby ensuring that the water temperature, water quality and surrounding air environment in the water tank 10 meet the maintenance requirements.

[0034] The flip cover design can also enhance the safety of the device, prevent people from accidentally touching the device and components inside the housing 40, and reduce safety risks caused by accidental touch, such as burns, mechanical injuries, etc.

[0035] The flip cover design can also improve the sealing and dustproofness of the equipment, effectively preventing dust, moisture, etc. from entering the curing box. This not only helps to protect the internal equipment and extend its service life, but also reduces equipment failure and damage caused by dust accumulation and moisture erosion. Good sealing can also help save energy and reduce energy consumption caused by heat loss or external heat ingress.

[0036] The flip cover design on the top of the housing 40 also makes the appearance of the curing box more complete and beautiful, and improves the overall image of the device. The closed top of the housing 40 prevents the internal equipment from being exposed, making the device look more neat and orderly, and meeting the requirements of modern industrial design.

[0037] Combined with reference Figure 2 and Figure 3 Two sets of lifting drive modules 30 are arranged in the housing 40. The lifting drive modules 30 use electric cylinders. The two sets of electric cylinders are symmetrically arranged on both sides of the water tank 10 and are respectively connected to one end of the cover plate 21. The electric cylinder is a device that converts electrical energy into mechanical energy, and has the characteristics of high precision, high stability and fast response speed. The electric cylinder includes a motor, a screw rod, a nut and other components. The motor drives the screw rod to rotate and drives the nut to move along the axial direction of the screw rod, thereby realizing the lifting and lowering movement of the test block bracket 20. The two sets of electric cylinders are symmetrically arranged to ensure that the test block bracket 20 is subjected to uniform force during the lifting process, which is conducive to the stable and precise lifting and lowering of the test block bracket 20, and can avoid tilting or shaking, providing reliable operation guarantee for loading and unloading of the test block.

[0038] Combined with reference Figures 1 to 3 The test block holder 20 is arranged in the water tank 10 and is used to load the test blocks to be cured (which may be cement test blocks, concrete test blocks or other test blocks that need to be cured). The test block holder 20 is arranged in a multi-row and multi-column form, and can load multiple batches of test blocks at the same time, thereby improving the curing efficiency. A cover plate 21 is provided on the top of the test block holder 20. The cover plate 21 can seal the top of the water tank 10 when the test block holder 20 is lowered into the water tank 10, thereby playing a sealing role and preventing water evaporation and external impurities from entering.

[0039] Optionally, the test block holder 20 is a modular combination structure, which is composed of a plurality of standard unit modules, and the number of layers and columns can be flexibly adjusted according to actual needs. Each unit module constitutes an independent test block placement slot, and the bottom of the placement slot is arranged in a tooth shape to avoid uneven curing of the bottom surface of the test block. The test block holder 20 can place the test block firmly and ensure that the test block can be evenly exposed to moisture and heat in the water to obtain a good curing effect.

[0040] Continue to refer to Figures 1 to 3 , the circulating pump is also arranged in the water tank 10. The circulating pump can make the water in the water tank 10 flow through the rotation of the impeller; the water is sucked in from the inlet of the circulating pump, and discharged from the outlet after being accelerated by the impeller, forming a circulation loop; in this process, the water flow continuously flushes various parts in the water tank 10, so that the water temperature is evenly distributed, and at the same time, the impurities in the water are taken away to maintain the stability of the water quality. Through the operation of the circulating pump, the water in the water tank 10 can continuously circulate, making the water temperature more uniform and avoiding the phenomenon of local temperature being too high or too low. At the same time, the circulating pump can also promote the uniform distribution of dissolved oxygen in the water, providing more favorable conditions for the maintenance of the test block. In addition, the water flow of the circulating pump can also prevent the precipitation of impurities in the water and keep the water quality clean.

[0041] In a specific embodiment, when the test block needs to be placed in the water tank 10 for curing, the left and right electric cylinders of the lifting drive module 30 work simultaneously, and the motor drives the screw rod to rotate, so that the nut moves upward, thereby driving the test block bracket 20 to rise. After the test block bracket 20 protrudes from the top of the water tank 10, the manipulator can place the test block to be cured in the test block bracket 20. The test block bracket 20 rises three layers each time to ensure that the arm span range of the manipulator is sufficient to fully cover the test block placement area of ​​the test block bracket 20. After the test block is placed, the lifting drive module 30 works again and drives the test block bracket 20 to descend, so that the test block is gradually immersed in the water of the water tank 10. When the test block bracket 20 descends to the preset position, the cover plate 21 on the top of the test block bracket 20 closes the water tank 10 to achieve sealing of the water tank 10. During the curing process of the test block, the circulating pump continues to work, so that the water in the water tank 10 circulates continuously to ensure uniform water temperature and clean water quality. The temperature control module 60 monitors the water temperature in real time and starts the heating or cooling equipment as needed to maintain the water temperature within the set range. After the test block maintenance is completed, the lifting drive module 30 works again to drive the test block bracket 20 to rise. After the test block is exposed to the water tank 10, the robot arm can take out the test block for subsequent testing or processing.

[0042] The curing box provided in the present application adopts a lifting structure design. Compared with the traditional drawer-type horizontal push-pull opening and closing method, no additional horizontal space is required to realize the opening and closing of the curing box, which can effectively save space and is particularly suitable for places with limited space. The cover plate 21 on the top of the test block bracket 20 can close the water tank 10 when the test block bracket 20 is lowered into the water tank 10, thereby reducing the possibility of water evaporation and the entry of external impurities, providing a more stable curing environment for the test block, and helping to improve the curing quality of the test block. The circulation pump allows the water in the water tank 10 to circulate continuously, ensuring that the water temperature is evenly distributed and the water environment around the test block is consistent, avoiding the difference in the curing effect of the test block caused by uneven water temperature; at the same time, the circulation of the water flow can also prevent the precipitation of impurities, ensure the clean water quality, and further improve the quality and reliability of the test block curing. The temperature control module 60 can accurately control the water temperature in the water tank 10, so that it remains within the set range, providing a stable temperature condition for the curing of the test block; stable temperature is crucial to the strength development and performance stability of the test block, and helps to improve the accuracy of the test block quality detection.

[0043] Furthermore, the water tank 10 includes a main chamber 11 and a sub-chamber 12. The sub-chamber 12 is arranged on one side of the main chamber 11 and is connected to the main chamber 11. The test block holder 20 is arranged in the main chamber 11, and the circulating pump is arranged in the sub-chamber 12, which can avoid the disturbance of the water balance in the main chamber caused by the turbulence generated when the circulating pump is running.

[0044] For details, please refer to Figure 2 and Figure 3 In the illustrated embodiment, the main cavity 11 and the auxiliary cavity 12 are integrally formed, and the cross-section is roughly convex in shape when viewed from above; the main cavity 11 is relatively large in size to accommodate the test block holder 20; the auxiliary cavity 12 is relatively small in size and can accommodate a circulating pump.

[0045] The main chamber 11 is the main part of the water tank 10, which is used to accommodate the test block holder 20 and the test blocks to be cured. At the same time, a large amount of curing water needs to be stored. The size of the space is designed according to the size of the test block holder 20 and the number of test blocks that need to be cured, and usually has a larger volume. The secondary chamber 12 is located on one side of the main chamber 11, and its volume is smaller than the main chamber 11. The main function of the secondary chamber 12 is to provide an installation space for the circulation pump, and by connecting with the main chamber 11, the flow of water between the main chamber 11 and the secondary chamber 12 is realized. The structural design of the secondary chamber 12 needs to take into account the convenience of installation and maintenance of the circulation pump, and at the same time ensure that the connecting pipe between the secondary chamber 12 and the main chamber 11 can provide smooth flow of water.

[0046] Specifically, when the circulating pump is working, the water in the secondary chamber 12 is pumped out, and then the water is transported to the main chamber 11 through the connecting pipe. When the water circulates in the main chamber 11, the test block can fully contact the flowing water, ensuring that the water temperature around the test block is uniform, which is beneficial to the maintenance of the test block. At the same time, the circulating water flow can prevent impurities from precipitating around the test block, keep the water clean, and provide better maintenance conditions for the test block. The water in the main chamber 11 can flow back to the secondary chamber 12 through the connecting pipe, forming a circulation loop. In this process, the circulating pump continues to work to maintain the circulation of water.

[0047] The reason why the circulation pump is arranged in the auxiliary chamber 12 is that if the circulation pump is directly installed in the main chamber 11, the rotation of the pump impeller will generate a large water flow impact force and disturbance, which may cause the water body in the main chamber 11 to fluctuate violently and destroy the equilibrium state of the water body. By arranging the circulation pump in the auxiliary chamber 12, when water flows from the auxiliary chamber 12 into the main chamber 11, the water flow speed and direction are adjusted to a certain extent through the buffering and diffusion of the connecting pipe, and after entering the main chamber 11, no excessive disturbance will be generated, thereby ensuring the relative stability of the water body in the main chamber 11 and providing a stable maintenance environment for the test block.

[0048] The circulating pump is installed in the secondary chamber 12, which can also reduce the direct impact and interference of the pump on the test block holder 20 and the test block in the main chamber 11, and reduce the risk of equipment damage due to water flow impact. At the same time, the stable water environment also helps to reduce the wear of the internal structure of the water tank 10, which is conducive to extending the service life of the entire curing tank.

[0049] The lifting curing box provided by the present application drives the test block holder 20 to move in the vertical direction by setting a lifting drive module 30, so that the test block holder 20 can enter and exit the water tank 10 from the open top, which greatly improves the space utilization rate and is particularly suitable for places with tight space. At the same time, the cover plate 21 on the top of the test block holder 20 can close the water tank 10 after it is lowered. Compared with the drawer-type structure, its sealing performance has been significantly improved, which is conducive to reducing the evaporation of water and the intrusion of external impurities, and can create a more stable and reliable curing environment for the test block, thereby improving the curing quality and consistency of the test block. By designing the water tank 10 as a main chamber 11 and a sub-chamber 12, and arranging the circulating pump in the sub-chamber 12, it is avoided that the turbulence generated by the operation of the circulating pump interferes with the water balance in the main chamber 11, so that the water temperature in the main chamber 11 can be kept evenly distributed, and the water quality and temperature conditions around the test block are consistent, providing a stable and consistent maintenance environment for the test block, which is beneficial to improving the quality and reliability of the test block maintenance, and making the test block quality detection results more accurate and reliable; the stable water environment is also beneficial to extending the service life of the test block bracket 20 and other related components, and reducing damage caused by water flow impact.

[0050] To summarize, the lifting curing box provided in this application effectively solves the problems of insufficient space utilization, poor sealing performance, unstable water environment, etc. existing in traditional curing boxes through the coordinated design and operation of various parts of the structure, and significantly improves the curing quality of the test blocks and the overall performance of the curing box.

[0051] Optionally, a multi-layer sealing structure is provided between the cover plate 21 and the water tank 10, and the multi-layer sealing structure includes: a sealing airbag, which is provided on the cover plate 21 and is arranged in a ring shape; an air pump, which is used to inflate the sealing airbag; a pressure sensor, which is used to detect the pressure between the cover plate 21 and the water tank 10; a first sealing ring, which is provided on the sealing airbag, and the shapes of the sealing airbag and the first sealing ring are adapted to the shape of the top surface of the water tank 10; when the cover plate 21 closes the water tank 10, the first sealing ring is compressed between the cover plate 21 and the water tank 10, and the pressure sensor detects the pressure between the cover plate 21 and the water tank 10, thereby triggering the air pump to inflate the sealing airbag; after the sealing airbag is inflated, additional pressure can be applied to the first sealing ring to make the first sealing ring contact more closely with the top surface of the water tank 10; after long-term use, if the water tank 10 or the cover plate 21 is worn, the sealing effect can also be ensured by adjusting the degree of expansion of the sealing airbag.

[0052] Specifically, the cover plate 21 is used to be connected to the top surface of the water tank 10 to seal the water tank 10. The back of the cover plate 21 facing the water tank 10 is provided with an annular groove matching the shape of the top surface of the water tank 10, and the annular groove is used to install sealing components such as a sealing airbag.

[0053] The sealing airbag is embedded in the annular embedding groove and is arranged in a ring shape along the annular embedding groove; the sealing airbag is made of a material with good elasticity and water resistance, such as rubber. The first sealing ring is arranged on the sealing airbag and faces the water tank 10; the first sealing ring is also made of a water-resistant and wear-resistant material, such as silicone, rubber, etc. When the cover plate 21 closes the water tank 10, the first sealing ring is compressed between the cover plate 21 and the water tank 10, directly contacts the top surface of the water tank 10, and can play a preliminary sealing role.

[0054] The air pump is used to inflate the sealed airbag. The air pump has a certain air pressure output capability and can control the amount of air inflated to the sealed airbag according to the signal of the pressure sensor; the air pump can be an electric air pump or other types of air source equipment, and the air pump is installed in the housing 40 and connected to the sealed airbag through a pipeline.

[0055] The pressure sensor is used to detect the pressure between the cover plate 21 and the water tank 10. The pressure sensor is installed on the cover plate 21 or the water tank 10, and can accurately sense the pressure changes between the two. The pressure sensor can transmit the detected pressure signal to the control system, and the control system can control the operation of the air pump according to the pressure situation.

[0056] More specifically, when the test block holder 20 descends to the cover plate 21 to close the water tank 10, the first sealing ring first contacts and is pressurized with the top surface of the water tank 10 to achieve a preliminary seal. At this time, the pressure sensor detects the pressure change between the cover plate 21 and the water tank 10, and transmits the pressure signal to the control system. After receiving the signal from the pressure sensor, the control system determines whether the pressure reaches the threshold that triggers the air pump to work. If the pressure does not reach the threshold, it means that the sealing effect may not be ideal. The control system will start the air pump to inflate the sealing airbag, and the sealing airbag will gradually expand. As the sealing airbag expands, it will apply additional pressure to the first sealing ring, making the first sealing ring more closely contact with the top surface of the water tank 10, thereby enhancing the sealing effect.

[0057] During long-term use, if the water tank 10 or the cover plate 21 is worn, the sealing performance between the two will be reduced. At this time, the pressure detected by the pressure sensor will change. The control system can control the air pump to work again according to the signal of the pressure sensor, and adjust the expansion degree of the sealing airbag by increasing or decreasing the inflation amount of the sealing airbag, thereby compensating for the gap caused by wear and tear, and thus ensuring the sealing effect.

[0058] The design of the multi-layer sealing structure, especially the coordinated work of the sealing airbag and the first sealing ring, can achieve efficient sealing of the water tank 10. Even if there are certain manufacturing errors or wear on the water tank 10 or the cover plate 21, the pressure compensation effect of the sealing airbag can still ensure a good sealing effect, effectively prevent the evaporation of water and the entry of external impurities, and provide a stable maintenance environment for the test block. The design of adaptive wear compensation can also extend the service life of the sealing structure and reduce maintenance costs and frequency.

[0059] Optionally, the multi-layer sealing structure also includes a second sealing ring, which is also arranged on the sealing airbag. The first sealing ring is wound around the second sealing ring. The first sealing ring is made of solid silicone rubber material, and the second sealing ring is made of polytetrafluoroethylene material. The second sealing ring can assist the first sealing ring to enhance the sealing effect, and because the second sealing ring has low friction characteristics, it can prevent the multi-layer sealing structure from being damaged due to excessive friction during the process of raising and lowering the cover plate 21.

[0060] Specifically, an annular groove is provided on the back of the cover 21, and a sealing airbag is embedded in the annular groove. A first sealing ring made of solid silicone rubber is provided on the sealing airbag; the first sealing ring has good elasticity and water resistance, and can adapt to a certain degree of deformation. When the cover 21 is lowered to contact the top surface of the water tank 10, the first sealing ring first fits tightly with the edge of the top of the water tank 10 to form the first sealing line of defense, which is used to block the leakage of most water and air. On the inner side of the first sealing ring and along the edge contour of the water tank 10, a circle of second sealing rings made of polytetrafluoroethylene material is arranged. Polytetrafluoroethylene has an extremely low friction coefficient and good chemical stability. After the cover 21 falls completely, the second sealing ring will further fit the water tank 10 to fill the tiny gap that may exist under the first sealing ring, thereby enhancing the sealing effect.

[0061] During the lifting and lowering process of the cover plate 21 with the test block bracket 20, the second sealing ring has low friction characteristics, which can reduce the friction between the multi-layer sealing structure and the edge of the water tank 10, avoid the multi-layer sealing structure from being damaged due to excessive friction, ensure the integrity of the sealing structure, extend the service life of the sealing structure, and reduce maintenance costs and replacement frequency. At the same time, the chemical stability and corrosion resistance of the polytetrafluoroethylene material help the second sealing ring to work stably for a long time in a humid maintenance environment.

[0062] Optionally, the multi-layer sealing structure also includes a magnetic module, and the cover plate 21 and the water tank 10 are provided with magnetic modules that can adsorb each other. When the cover plate 21 is lowered, the corresponding magnetic modules attract each other, which can prompt the cover plate 21 to align with the water tank 10, and can provide additional adsorption force after the cover plate 21 is pressed against the water tank 10, thereby enhancing the sealing effect.

[0063] The magnetic attraction module can be two magnets that attract each other with opposite charges, or a magnet matched with a metal block, or at least one electromagnet.

[0064] In one embodiment, a circle of multiple metal blocks is provided on the cover plate 21 along the annular path on the top surface of the water tank 10, and a circle of multiple electromagnets is correspondingly provided on the water tank 10; when the water tank 10 is closed, the electromagnets are energized to adsorb the metal blocks; when the test block bracket 20 is raised or lowered, the electromagnets are de-energized to facilitate the rise of the cover plate 21.

[0065] Specifically, during the process of the cover plate 21 descending, the electromagnet on the water tank 10 and the metal block on the cover plate 21 attract each other. This attraction can cause the cover plate 21 to accurately align with the water tank 10, thereby ensuring the correct installation of the sealing structure and improving the convenience and accuracy of the operation. After the cover plate 21 is pressed against the water tank 10, the electromagnet continues to provide additional adsorption force, which can enhance the sealing effect.

[0066] The magnetic module works together with the first sealing ring, the second sealing ring and the sealing airbag to improve the reliability and stability of the entire sealing system.

[0067] Optionally, the multi-layer sealing structure also includes a humidity sensor, which is arranged in the water tank 10. When the cover plate 21 closes the water tank 10, the humidity sensor is adjacent to the first sealing ring. The humidity sensor is used to monitor the humidity changes in the sealing area. When the humidity sensor detects that the humidity in the sealing area is abnormal, it indicates that there is a sealing leakage. The air pump is started to increase the expansion degree of the sealing airbag to make up for the gap causing the leakage.

[0068] In one embodiment, the multi-layer sealing structure includes a plurality of humidity sensors, which are installed in the water tank 10 and close to the top surface of the water tank 10. When the cover plate 21 closes the water tank 10, the humidity sensor is close to the first sealing ring, which is conducive to ensuring that the detection range fully covers the connection part between the cover plate 21 and the water tank 10.

[0069] The humidity sensor can monitor the humidity changes in the sealing area (i.e., the connection between the cover plate 21 and the water tank 10) to determine whether there is a sealing leakage problem. Specifically, after the cover plate 21 closes the water tank 10, the humidity sensor starts working. If the humidity in the sealing area rises abnormally, it means that there may be a sealing leakage; the humidity sensor transmits relevant information to the control system; after detecting the sealing leakage, the control system will first determine the severity of the leakage. If it is a minor leakage, the system can start the air pump to increase the expansion degree of the sealing airbag, so that the first sealing ring and the water tank 10 are in closer contact, thereby filling the gap of the leakage and restoring a good sealing state. If the leakage is more serious, the system will sound an alarm and remind manual intervention.

[0070] The humidity sensor can monitor the humidity changes in the sealing area in real time, detect problems in time, and avoid the deterioration of the test block curing environment due to leakage. When a leak is detected, the system can automatically start the air pump to increase the expansion of the sealing airbag to make up for the leakage gap, realize automatic compensation and repair of the sealing system, and improve the intelligence level and reliability of the equipment.

[0071] Optionally, the water tank 10 is provided with an inlet pipe and an outlet pipe, the inlet pipe is connected to the water supply equipment, and the outlet pipe is used for drainage; the lifting maintenance box also includes an intelligent inlet and outlet module, the intelligent inlet and outlet module is used to monitor the water environment in the water tank 10, and the intelligent inlet and outlet module includes: a water quality sensor, used to monitor the pH, hardness, microbial content and other indicators of the water in the water tank 10; a water level sensor, used to monitor the water level in the water tank 10; a first valve, arranged on the inlet pipe; a second valve, arranged on the outlet pipe; the intelligent inlet and outlet module can open and close the first valve or the second valve according to the information feedback from the water quality sensor and the water level sensor, so as to facilitate operations such as water replenishment and water change on demand.

[0072] Specifically, the water tank 10 is used as the main place for curing the test block, and is used to store curing water. The test block is immersed in water for curing. A water inlet pipe is provided on one side of the water tank 10, and the water inlet pipe is connected to the water supply equipment, which can provide water for the water tank 10 to meet the needs of water replenishment and water replacement. A water outlet pipe is also provided on one side of the water tank 10, and the water outlet pipe is used to discharge the water in the water tank 10 to achieve operations such as water replacement.

[0073] In one embodiment, the water supply device includes a reserve water tank, which is arranged on one side of the water tank 10, and a valve is arranged on the connecting pipe between the two; the reserve water tank has a certain volume and can also store water, and when needed, the valve is opened to input water into the water tank 10. The reserve water tank can be automatically replenished with water through an external water pipe at ordinary times, and can also be replenished manually as needed.

[0074] In another embodiment, the water supply device is an external water source, and the water inlet pipe of the water tank 10 is equipped with a valve and a pump, which can actively pump water from the external water source as needed.

[0075] In another embodiment, the lifting curing box further includes a moving module 50, which can drive the lifting curing box to move. The water tank 10 is also provided with an automatic docking device; when necessary, the moving module 20 can carry the entire curing box to the water source, and the automatic docking device can automatically extend the water inlet pipe and connect to the water source, and then pump water to the water tank 10.

[0076] More specifically, the water quality sensor is used to monitor the pH, hardness, microbial content and other indicators of the water in the water tank 10 in real time to evaluate the water quality; for example, the pH sensor determines the pH by measuring the hydrogen ion concentration in the water; the hardness sensor determines the hardness of the water by detecting the calcium and magnesium ion content in the water; the microbial content sensor may use optical, electrical and other methods to detect the number of microorganisms in the water.

[0077] The water level sensor is used to monitor the water level height in the water tank 10 to provide a basis for water replenishment and drainage operations; the water level sensor measures the height of the water level in the water tank 10, converts the water level information into an electrical signal or other identifiable signal, and feeds it back to the control system; common water level sensors include float type, pressure type, etc.

[0078] The first valve is installed on the water inlet pipe to control the on and off of the water inlet pipe to achieve water inlet operation. The second valve is installed on the water outlet pipe to control the on and off of the water outlet pipe to achieve drainage operation. The first valve and the second valve use automatic valves such as solenoid valves, and the opening and closing of the valves are controlled by electrical signals sent by the control system. When the control system determines that the valve needs to be opened or closed, it will send a corresponding electrical signal to the valve to make the valve perform the corresponding action.

[0079] In one embodiment, the water quality sensor and the water level sensor continuously monitor the water quality and water level in the water tank 10, and feed back the monitoring data to the control system of the intelligent water inlet and outlet module in real time. The control system analyzes the feedback information according to the preset water quality and water level standards, and determines whether water replenishment or water change operation is required. If water replenishment is required, the control system will open the first valve and control the amount of water replenishment according to the feedback from the water level sensor. When the water level reaches the set upper limit, the first valve is closed and the water replenishment is stopped. If the water needs to be changed, the control system first opens the second valve to drain the water in the water tank 10. During the drainage process, the water level sensor monitors the water level changes in real time. When the water level drops to the set lower limit, the second valve is closed, and then the first valve is opened to replenish water until the water level reaches the appropriate height.

[0080] By using the water quality sensor to monitor the water quality in real time, the intelligent water inlet and outlet module can detect water quality abnormalities in a timely manner, and ensure that the water quality in the water tank 10 meets the requirements of test block maintenance through operations such as water replacement, thereby improving the maintenance quality of the test block. By using the water level sensor to monitor the water level in real time, the intelligent water inlet and outlet module can accurately control the amount of water in the water tank 10 to avoid water overflow due to excessively high water levels, or to prevent the maintenance effect of the test blocks from being affected due to excessively low water levels.

[0081] Optionally, a filter module is provided in the water inlet pipe, and the filter module can filter out impurities in the water; In one embodiment, the filtration module adopts a multi-layer filtration structure to meet the strict requirements of test block maintenance on water quality. Specifically, the multi-layer filtration structure includes a first layer of coarse filter, a second layer of fine filter and a third layer of filter element. When water enters, the water flows through the first layer of coarse filter, the second layer of fine filter and the third layer of filter element in sequence. The mesh of the first layer of coarse filter is larger, which is used to intercept large particles of impurities, such as mud, gravel, etc. The mesh of the second layer of fine filter is smaller, which can further filter small particles of impurities. The third layer of filter element can adopt an activated carbon filter element, which is used to adsorb organic matter, odor and some heavy metal ions in the water. The third layer of filter element can choose different materials and types according to actual needs. For example, a ceramic filter element can filter bacteria and microorganisms.

[0082] The multi-layer filtration structure achieves the gradual filtration of impurities in the water through the combination of different filtration layers. The coarse filter first intercepts large particles of impurities, the fine filter further intercepts smaller impurities, and the filter element removes organic matter, microorganisms and some heavy metal ions in the water through adsorption and filtration. The filtration principles and effects of different filtration layers complement each other to achieve a higher water purification effect. The filtration module of the multi-layer filtration structure can effectively remove various impurities in the water, meet the strict requirements of the test block maintenance on water quality, provide a good maintenance environment for the test block, and improve the quality and performance of the test block.

[0083] In order to facilitate the long-term use of the filter module, in one embodiment, the filter module is detachably arranged in the water inlet pipe. For example, the filter module is arranged in the water inlet pipe by threaded connection, snap connection, etc., which is convenient for disassembly and installation.

[0084] The detachable structure design facilitates regular maintenance and replacement of filter elements. As the use time increases, the filter screen and filter element on the filter module will gradually accumulate impurities, resulting in a decrease in the filtering effect. Through the detachable design, the filter element can be easily replaced or cleaned to restore the filtering performance of the filter module. The detachable filter module design makes it easier to replace and clean the filter element, reducing maintenance costs and difficulties.

[0085] In another embodiment, a flushing pipe and a bypass pipe are further provided on the water inlet pipe, and the filter module is located between the flushing pipe and the bypass pipe. Valves are provided on the flushing pipe and the bypass pipe, and the valves are electromagnetic valves or other automatic valves. During the normal water inlet process, the flushing pipe and the bypass pipe are closed, the first valve is opened, and water flows in from the water inlet pipe, passes through the filter module, and the filter module intercepts and filters the impurities in the water, and finally the clean water enters the water tank 10. When the filter module needs to be cleaned, the first valve is closed to stop the water inlet; the flushing pipe and the bypass pipe are opened, and the high-pressure water flow rushes from the flushing pipe to the filter module. The impact direction of the high-pressure water flow is opposite to the water inlet direction of the water inlet pipe. The high-pressure water flow can reversely flush the filter module, and flush the impurities intercepted on the filter module to the bypass pipe. Finally, the impurities are discharged through the bypass pipe with the water flow.

[0086] By setting up flushing pipes and bypass pipes, the filter module can be cleaned regularly, which helps to extend the service life of the filter module and ensure the filtering effect.

[0087] Optionally, the water tank 10 is provided with an overflow port, and the water can be discharged from the overflow port when the water level is too high.

[0088] Specifically, the overflow port is arranged at a higher position of the water tank 10 to ensure that water can be discharged from the overflow port when the water level is too high. Under normal circumstances, the water level in the water tank 10 is lower than the overflow port, and the overflow port does not discharge water. When the water level in the water tank 10 is too high and exceeds the overflow port due to some reason (such as excessive water intake or water level sensor failure), water will flow out of the overflow port under the action of gravity, thereby maintaining the stability of the water level in the water tank 10.

[0089] The setting of the overflow port can timely discharge the excess water in the water tank 10, prevent the water level in the water tank 10 from being too high and causing water overflow, and protect the curing box and the surrounding environment.

[0090] Optionally, the overflow port is connected to a drain pipe, and the overflowed water is finally discharged through the drain pipe.

[0091] Optionally, the lifting maintenance box provided in the present application also includes a cleaning module, which is used to clean the inside of the water tank 10. The cleaning module includes: a telescopic robotic arm, with a cover plate 21 away from the water tank 10. After the top of the water tank 10 is opened, the telescopic robotic arm can reach into the water tank 10; a rotary drive, which is arranged at the execution end of the telescopic robotic arm; a nozzle, which is arranged at the execution end of the rotary drive; during cleaning, the telescopic robotic arm can drive the rotary drive to carry the nozzle into the water tank 10 from top to bottom, so that the nozzle can spray water onto the inner wall of the water tank 10 to clean the inner wall of the water tank 10.

[0092] The cleaning module can be built into the maintenance box, which is located inside the outer shell 40 and on one side of the water tank 10; it can also be external, and when cleaning is required, the mobile module 50 carries the entire maintenance box to the cleaning module.

[0093] Specifically, the telescopic robot arm has a telescopic structure, usually composed of multiple segments, and the segments are mechanically connected to achieve the telescopic function. The telescopic robot arm usually adopts screw drive, chain drive or hydraulic drive, and is powered by a motor or hydraulic pump to enable the various segments of the robot arm to achieve relative movement, thereby changing the length of the robot arm. This telescopic structure can flexibly adjust the position of the nozzle, allowing it to penetrate deep into the water tank for cleaning.

[0094] The rotary driver is installed at the execution end of the telescopic mechanical arm, and its main function is to drive the nozzle to rotate. The rotary driver can use a driving member such as a motor and a rotary cylinder, which can accurately control the rotation angle and speed of the nozzle to achieve comprehensive cleaning of different positions and angles of the inner wall of the water tank 10.

[0095] The nozzle is installed at the execution end of the rotary drive, and the nozzle can spray water at a suitable pressure and angle to achieve the best cleaning effect. The nozzle can adopt different water spraying modes, such as fan-shaped water spraying, cone-shaped water spraying, etc., to meet the cleaning needs of different parts of the inner wall of the water tank 10. The nozzle is connected to the water source (which can be the water supply equipment mentioned above) through a pipeline to ensure that there is enough water supply during the cleaning process.

[0096] More specifically, when the water tank 10 needs to be cleaned, the test block bracket 20 is raised and the cover plate 21 is away from the water tank 10, and the top of the water tank 10 is opened to provide a channel for the telescopic robotic arm to reach into the water tank 10; the telescopic robotic arm starts to work, driving the rotary drive carrying the nozzle to extend into the water tank 10 from top to bottom; during the extension process, the telescopic robotic arm can adjust its telescopic length according to the depth of the water tank 10 and cleaning requirements, to ensure that the nozzle can reach various depth positions of the water tank 10; the rotary drive is started to drive the nozzle to rotate. The nozzle obtains water through a pipe connected to a water source, and sprays water toward the inner wall of the water tank 10 at a certain pressure and angle; the rotary driver can adjust the rotation speed and angle of the nozzle according to a preset program or control signal, so that the nozzle can cover various areas of the inner wall of the water tank 10; as the telescopic mechanical arm descends and the nozzle rotates, various parts of the inner wall of the water tank 10 can be sprayed with water, and the impact force of the water flow can wash away the dirt, impurities, etc. on the inner wall of the water tank 10; when the telescopic mechanical arm descends to the bottom of the water tank 10 and completes the cleaning of the entire inner wall of the water tank 10, the telescopic mechanical arm starts to rise, and the rotary driver and the nozzle are removed from the water tank 10; the water source and the rotary driver are turned off to complete the cleaning operation.

[0097] The cooperation of the telescopic mechanical arm and the rotary drive enables the nozzle to penetrate into the water tank 10 and cover various areas of the inner wall of the water tank 10, thereby achieving comprehensive cleaning of the water tank 10. Compared with the traditional manual cleaning method, the cleaning efficiency is greatly improved, and the cleaning time and labor cost are reduced.

[0098] If necessary, the cleaning module can also clean the test block holder 20 .

[0099] Optionally, the lifting and curing box provided in the present application also includes an outer shell 40, and the water tank 10, the lifting and curing drive module 30 and the temperature control module 60 are all arranged in the outer shell 40; the water tank 10 is made of transparent material, and the outer shell 40 is provided with an observation window made of transparent material, and workers can see the curing status of the test blocks in the water tank 10 through the observation window.

[0100] For details, please refer to Figure 1 In the illustrated embodiment, the housing 40 integrates the water tank 10, the lifting drive module 30, the temperature control module 60 and other components, making the structure of the entire curing box more compact, occupying less space, easy to install and use, and suitable for different workplaces. A transparent observation window is provided on the upper part of the front of the housing 40. Since the water tank 10 is made of transparent material, workers can see the situation inside the water tank 10 through the observation window. When the test block is cured in the water tank 10, the worker can check the status of the test block through the observation window, such as the appearance change of the test block, the water level, etc., without opening the curing box, thereby avoiding damage to the curing environment.

[0101] The observation window is made of transparent material, installed on the housing 40, and located directly opposite the water tank 10, so that workers can observe the curing status of the test block in the water tank 10. The transparent material of the observation window should have good light transmittance and wear resistance to ensure that the observation effect is not affected during long-term use.

[0102] Optionally, the observation window uses tempered glass. Tempered glass is ordinary glass that has been strengthened by heat treatment. It has high strength and impact resistance and can effectively prevent breakage due to external force collision. The light transmittance of tempered glass is usually around 80% to 90%, which can clearly display the situation inside the water tank 10. At the same time, the surface hardness of tempered glass is high, the wear resistance is good, it is not easy to be scratched, and it can maintain a good observation effect after long-term use. In addition, tempered glass also has good thermal stability, can withstand certain temperature changes, and adapt to the temperature environment in the curing box.

[0103] In other embodiments, the observation window may also be made of polycarbonate (PC) board, acrylic (plexiglass, PMMA), quartz glass, etc. The present application does not limit the specific material of the observation window.

[0104] The water tank 10 can be made of transparent glass or transparent plastic (such as polycarbonate, etc.). This transparent material allows the internal conditions of the water tank 10 to be clearly visible, providing conditions for observing the curing conditions of the test blocks.

[0105] Optionally, the water tank 10 is made of double-layer high borosilicate glass material, and the surface of the inner glass is treated with a nano-hydrophobic coating to prevent scale adhesion.

[0106] The transparent design of the water tank 10 and the observation window enables workers to easily observe the curing status of the test block without opening the curing box, thus avoiding interference with the curing environment and ensuring the stability of the test block curing environment. By observing the status of the test block, workers can find problems in time and take corresponding measures.

[0107] Optionally, a heat dissipation hole 41 is further provided on the housing 40 , and the heat dissipation hole 41 faces the temperature control module 60 .

[0108] For details, please refer to Figure 1 In the illustrated embodiment, an array of heat dissipation holes 41 are provided at the lower portion of the front side of the housing 40. The heat dissipation holes 41 are located below the observation window and aligned with the temperature control module 60. In this way, the heat generated by the temperature control module 60 can be directly dissipated to the outside through the heat dissipation holes 41, thereby reducing the accumulation of heat inside the housing 40.

[0109] Specifically, the temperature control module 60 generates heat during operation, and the heat is transferred to the housing 40 by heat conduction and heat convection. Since the heat dissipation holes 41 face the temperature control module 60, air forms convection inside and outside the heat dissipation holes 41, and the external cold air enters the housing 40 through the heat dissipation holes 41, taking away the heat around the temperature control module 60, and the hot air is discharged to the outside through the heat dissipation holes 41. In this way, the heat dissipation holes 41 can effectively help the temperature control module 60 dissipate heat, ensuring that the temperature control module 60 can work normally within a suitable temperature range.

[0110] Optionally, the lifting maintenance box provided in the present application also includes an intelligent environment monitoring module, which is arranged in the outer shell 40. The intelligent environment monitoring module includes a temperature sensor, a humidity sensor, a carbon dioxide sensor and a particulate matter sensor, which can monitor environmental parameters in all directions to facilitate the adjustment of the maintenance environment.

[0111] Specifically, the intelligent environment monitoring module is arranged in the housing 40, and is composed of a temperature sensor, a humidity sensor, a carbon dioxide sensor, and a particle sensor. The temperature sensor measures the temperature by using the principle of thermal expansion and contraction of an object and the change of resistance with temperature, so as to monitor the air temperature in the housing 40. The humidity sensor measures the humidity by detecting the influence of water molecules on the physical or chemical properties of certain materials, so as to monitor the air humidity in the housing 40. The carbon dioxide sensor detects the carbon dioxide concentration by using the principles of infrared absorption, electrochemistry, etc., so as to monitor the carbon dioxide concentration in the housing 40. The particle sensor detects the particle content in the air by using the principles of light scattering, electrostatic induction, etc., so as to monitor the particle content in the housing 40. These sensors can also convert the detected signals into electrical signals or other identifiable signals, and transmit them to the control system for processing and analysis.

[0112] More specifically, after the test block support 20 is raised, these sensors transmit the detected information such as temperature, humidity, carbon dioxide concentration and particulate matter content to the control system. The control system can determine whether the current environment meets the requirements according to the preset maintenance environment standards, and adjust the working status of the temperature control module 60, water inlet and outlet system and other equipment as needed to optimize the maintenance environment. In normal times, it can also assist in monitoring whether there is a leak in the water tank 10; for example, when the water tank 10 leaks, it will cause the surrounding air humidity to change, and the humidity sensor can detect this abnormality. Once the abnormal change is detected, the control system can handle it in time or issue an alarm and notify the workers to check and handle it.

[0113] The intelligent environmental monitoring module can monitor the environmental parameters in the curing box in all directions and detect environmental changes and abnormal conditions in a timely manner. During the curing process of the test block, the curing environment is adjusted according to the feedback of the environmental parameters to provide more suitable curing conditions for the test block. At the same time, it assists in monitoring the leakage of the water tank 10, improving the reliability and safety of the equipment.

[0114] Optionally, a display screen is also provided on the surface of the shell 40, and workers can set and view various parameters of the lifting maintenance box through the display screen.

[0115] Among them, the display screen can adopt a touch screen to facilitate the workers to operate. The display screen has a high resolution and sensitivity, can clearly display various information, and accurately respond to the workers' touch operations. Workers can set and view various parameters of the lifting curing box through the display screen, such as the water temperature and water level in the water tank 10, the temperature and humidity of the environment, etc.; at the same time, the curing environment can also be adjusted through the display screen, including controlling water inlet, drainage, heating, cooling, etc. If necessary, the test block bracket 20 can also be manually controlled to rise and fall, so as to facilitate the loading and unloading of test blocks at any time as needed. The display screen can also display the operating status of the equipment, fault information, etc., which is convenient for workers to maintain and manage the equipment.

[0116] Specifically, the display screen is connected to the control system of the curing box, and the settings and operation instructions input by the workers through the touch screen, such as adjusting the water temperature, controlling the lifting of the test block bracket 20, etc., will be transmitted to the control system. According to these instructions, the control system controls the corresponding equipment (such as the temperature control module 60, the lifting drive module, the inlet and outlet valves, etc.) to perform operations. At the same time, the operating status and various parameter information of the equipment will also be fed back to the display screen in real time for workers to view and monitor. For example, when the temperature control module 60 is working, the display screen will display the current water temperature and the working status of the temperature control module 60; when the test block bracket 20 is lifted, the display screen will display the position information of the test block bracket 20.

[0117] The display screen provides a convenient operation interface for workers. Workers can easily set and view various parameters of the curing box through the display screen to achieve precise control of the curing environment. Manual control of the test block bracket 20 lifting and lowering functions also increase the flexibility of operation. Real-time display of equipment operating status and fault information facilitates workers to maintain and manage the equipment, which is conducive to improving work efficiency and reducing maintenance costs.

[0118] Optionally, the liftable maintenance box provided in the present application also includes a mobile module 50, which is connected to the outer shell 40 and can drive the liftable maintenance box to move; the mobile module 50 is hidden in the outer shell 40; a charging interface 51 is provided on one side of the outer shell 40, and the mobile module 50 can carry the outer shell 40 to the power source and realize automatic charging through the charging interface 51.

[0119] In one embodiment, the mobile module 50 uses an AGV (automatic guided vehicle) trolley. The AGV trolley is mainly composed of a drive motor, wheels, a navigation system (such as laser navigation, visual navigation, etc.), a battery and other components. The drive motor is used to provide power for the wheels so that the maintenance box can move on the ground; the navigation system can help the maintenance box to travel along a preset path and avoid obstacles; the battery can provide power support for the mobile module 50 and other equipment in the maintenance box.

[0120] For details, please refer to Figures 1 to 3 In the illustrated embodiment, the housing 40 is configured in a cover shape, and a mounting frame 42 is provided inside the housing 40, on which the water tank 10, the lifting drive module 30, and the temperature control module 60 are provided. Below the mounting frame 42, there is a small shielding space inside the housing 40, and the mobile module 50 is provided in the shielding space, with only the wheels exposed. This design protects the mobile module 50 without affecting its normal operation and the mobile maintenance box.

[0121] continue Figure 1 and Figure 2 A charging interface 51 is provided on one side of the housing 40 for connecting to a power source and charging the mobile module 50. The charging interface 51 may be a common charging interface type, such as a USB interface, a Type-C interface, or a dedicated charging interface, depending on the battery type and charging requirements of the mobile module 50.

[0122] Specifically, when the battery of the mobile module 50 is low, the navigation system can guide the maintenance box to the power source. After arriving, the charging interface 51 automatically docks with the power socket and starts charging the battery of the mobile module 50. During the charging process, the mobile module 50 stops moving to ensure the stability and safety of charging.

[0123] Optionally, the water supply device and the cleaning module are arranged near the power source. In this way, water change and / or cleaning operations can be performed while the maintenance box is being charged. For example, during charging, the intelligent water inlet and outlet module can control the water change of the water tank 10, drain the dirty water, and then use the water supply device to replenish clean water; the cleaning module can clean the water tank 10 to ensure that the internal environment of the water tank 10 is clean.

[0124] In summary, the mobile module 50 enables the lifting maintenance box to have the function of autonomous movement, and can be flexibly moved to different positions as needed to adapt to different working environments and site layouts. This improves the convenience and flexibility of the maintenance box and reduces the workload and labor intensity of manual handling. The peripherals of the charging interface 51 enable the mobile module 50 to have an automatic charging function, which reduces the operation of manual charging and improves the efficiency of equipment use. When the water supply equipment and the cleaning module are set near the charging area, the maintenance box can perform operations such as changing water and cleaning while charging, realizing multi-functional integration and further improving the efficiency and intelligence of the equipment.

[0125] The present application also provides a cement stone testing system, including the above-mentioned lifting curing box, and also includes: a water absorption device 1, which is arranged in a door frame shape, and a water absorption strip is arranged on the inner wall of the door frame structure. When the cement test block passes through the water absorption device 1, the water absorption strip can absorb the moisture on the surface of the cement test block, providing good conditions for subsequent tests; a barcode scanner 2, which is arranged downstream of the water absorption device 1, and is used to scan the QR code on the cement test block, so as to confirm the identity of the cement test block, so as to record the progress information of the cement test block in the test process in real time; an anti-flexure device 3, which is used to perform an anti-flexure test on the cement test block after scanning the code, and can measure the anti-flexure strength of the cement test block, and transmit the test data to the data processing system in real time; a compression device 4, which is used to perform a compression test on the cement test block after the flexure test, and can measure the compressive strength of the cement test block, and transmit the test data to the data processing system in real time, so as to understand the quality of the cement test block; a recovery box 5, which is arranged downstream of the compression device 4, and is used to receive the cement test block that has completed the compression test.

[0126] For details, please refer to Figure 4 In the illustrated embodiment, the cement block testing system further includes a six-axis manipulator 6, which can be connected to a lifting curing box and other devices to realize the transfer of cement test blocks.

[0127] Continue to refer to Figure 4 , a six-axis manipulator 6 is arranged on one side of the lifting curing box, and a workbench 7 is arranged next to the six-axis manipulator 6, on which a water absorption device 1, a barcode scanner 2, an anti-bending device 3 and an anti-pressure device 4 are arranged. The water absorption device 1 is closest to the lifting curing box. The water absorption device 1 is arranged in the shape of a door frame, including two vertical pillars and a horizontal connecting column, and water absorption strips are arranged on the inner walls of the vertical pillars and the horizontal connecting column. The water absorption strips are made of materials with good water absorption, such as cloth or sponge. These materials have rich pore structures and can absorb moisture on the surface of the test block through capillary action, so that the surface of the test block reaches a dry state, so as to meet the requirements of subsequent tests for the surface humidity of the test block.

[0128] Continue to refer to Figure 4, the barcode scanner 2 is arranged downstream of the water absorption device 1 in a straight line direction. After passing through the water absorption device 1, the cement test block will move into the scanning area of ​​the barcode scanner 2. The barcode scanner 2 can scan the QR code on the cement test block, and confirm the identity information of the cement test block by scanning the code, so as to record the progress of the test block in the test process in real time and realize accurate tracking and management of the test block.

[0129] Continue to refer to Figure 4 The anti-bending device 3 is arranged on the side of the water absorbing device 1 away from the lifting curing box. The anti-bending device 3 includes a loading device (such as a hydraulic loading system or a mechanical loading device), a supporting structure (for fixing and supporting the test block) and a sensor (such as a force sensor and a displacement sensor). The loading device can apply a gradually increasing anti-bending force to the test block on the supporting structure, the supporting structure can ensure that the test block remains stable during the test, and the sensor can monitor the force and displacement of the test block in real time, thereby measuring the anti-bending strength of the cement test block.

[0130] Specifically, the six-axis manipulator 6 places the scanned cement test block on the support structure of the anti-flexural device 3. The loading device applies anti-flexural force at a certain rate. The test block deforms during the force application process. The sensor collects force and displacement data in real time. When the test block breaks, the anti-flexural strength of the test block is calculated based on the collected data, and the data is transmitted to the data processing system in real time.

[0131] Continue to refer to Figure 4 The anti-compression device 4 is arranged on the side of the anti-bending device 3 away from the water absorbing device 1. The anti-compression device 4 mainly includes a loading platform, a pressure sensor and a displacement measuring device. The loading platform is used to place the test block and apply pressure, the pressure sensor can measure the magnitude of the applied pressure, and the displacement measuring device is used to monitor the deformation of the test block during the pressure process.

[0132] Specifically, after passing through the anti-bending device 3, the cement test block is broken into two sections, and the six-axis manipulator 6 removes the broken cement test blocks one by one and puts them into the anti-compression device 4; the cement test block is placed on the loading platform, and the anti-compression device 4 controls the loading platform to gradually apply pressure, and the pressure sensor and the displacement measuring device collect data in real time. When the test block reaches the compressive limit of failure, the compressive strength of the test block is calculated based on the collected data, and the data is transmitted to the data processing system in real time.

[0133] Continue to refer to Figure 4 , the recycling box 5 is arranged on the side of the workbench 7 away from the six-axis manipulator 6. The compression device 4 is between the six-axis manipulator 6 and the recycling box 5. The compression device 4 also includes a pusher for pushing the cement test block to the test station. After the compression test is completed, the loading platform releases the test block, and the pusher approaches and continues to push the test block forward, so that the test block falls into the recycling box 5. The recycling box 5 is used to receive the cement test block that has completed the compression test so that the test block can be subsequently processed or recycled.

[0134] In a specific embodiment, after the cement test block completes curing in the lifting curing box, the test block bracket 20 is lifted by the lifting drive module 30 to facilitate the six-axis manipulator 6 to take out the test block. The six-axis manipulator 6 delivers the test block so that the test block passes through the water absorption device 1. The water absorption strip absorbs the moisture on the surface of the test block to dry the surface of the test block. The dried test block continues to move forward and reaches the scanning area of ​​the barcode scanner 2. The barcode scanner 2 scans the QR code on the test block to confirm the identity of the test block, and transmits the relevant information to the data processing system to record the progress of the test block in the test process. After scanning the code, the six-axis manipulator 6 withdraws the test block and delivers the test block to the anti-flexure device 3 for an anti-flexure test. The anti-flexure device 3 measures the flexural strength of the test block and transmits the test data to the data processing system in real time. After the flexural test is completed, the test block is folded into two sections, and the six-axis manipulator 6 withdraws the test blocks one by one and delivers them to the compression device 4 one by one for the compression test. The compression device 4 measures the compressive strength of the test block and transmits the test data to the data processing system in real time. The test block that has completed the compression test is pushed into the recovery box 5 by the pusher to wait for subsequent processing.

[0135] The cement stone test system provided in the present application removes moisture from the surface of the test block through the water absorption device 1, which can avoid the interference of moisture on the test results, make the flexural and compression test data more accurate and reliable, and improve the accuracy and credibility of the test results. The progress information of the test block in the test process can be recorded in real time by the barcode scanner 2, which is convenient for the operator to track and manage the test block, ensure the orderly progress of the test process, and also facilitate the sorting and analysis of the test data. The test data can be transmitted to the data processing system in real time through the anti-flexural device 3 and the compression device 4, realizing the automatic collection and processing of data and improving work efficiency. The test blocks that have completed the test can be collected through the recycling box 5, so as to facilitate the unified recycling and processing of the test blocks, which meets the requirements of environmental protection and resource recycling.

[0136] The cement block testing system provided by the present application solves the problem of water interference through the water absorption device 1, realizes accurate identification and tracking of the test block identity through the barcode scanner 2, improves the test efficiency and accuracy through the automatic data collection of the anti-bending device 3 and the anti-compression device 4, and facilitates the recycling of the test block through the recycling box 5. The cement block testing system provided by the present application can complete the testing of cement test blocks more accurately and efficiently, and provide a more reliable basis for the evaluation of cement quality.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
