Description

Technical Field

[0001] This invention relates to the field of concrete curing technology, and more particularly to an energy-saving concrete curing box test block placement component. Background Technology

[0002] A concrete curing chamber is a specialized device used for the standard curing of concrete specimens. By precisely controlling the temperature, humidity, and ventilation conditions inside the chamber, it simulates the hydration and hardening process of concrete in a natural environment, ensuring the accuracy of specimen strength test results. It is widely used in building laboratories, quality inspection centers, construction sites, and other scenarios, and is one of the core devices for concrete quality control.

[0003] In practical applications of concrete curing, existing concrete curing chambers generally adopt a monolithic, single-environment design. This structural characteristic makes them difficult to adapt to diverse curing needs, causing numerous inconveniences for construction testing and experimental research. Specifically, construction projects often require the simultaneous curing of different types and uses of concrete test blocks. However, the internal space of existing curing chambers is a fully connected structure, and the temperature and humidity control system can only implement uniform parameter control for the entire chamber, failing to achieve environmental zoning for different areas within the chamber. This results in test blocks with various curing requirements not being able to be placed for curing simultaneously, necessitating either batch curing, extending the testing cycle, or the purchase of multiple additional curing chambers, increasing equipment investment costs.

[0004] Therefore, it is necessary to design an energy-saving concrete curing box test block placement component to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an energy-saving concrete curing box test block placement component.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An energy-saving concrete curing chamber test block placement assembly includes a curing chamber body and a door hinged to the opening of the curing chamber body. The inner wall of the curing chamber body has several partitions arranged in a linear array. The top surface of each partition has several connecting openings. Guide rails are fixedly installed on the inner wall of the curing chamber body directly above the partitions. Placement plates are slidably installed on the inner walls of the guide rails. Temperature control mechanisms are installed on the inner wall of the curing chamber body directly above each guide rail. Placement components for placing concrete test blocks are installed on the top surface of each placement plate. Sealing components for separating enclosed spaces are installed on the top surface of each partition. Control components for linking the placement components and the sealing components are installed on the sides of the placement plates.

[0007] As a preferred embodiment of the present invention, the temperature control mechanism includes a temperature control tube disposed on the inner wall of the curing chamber, a control valve disposed on the temperature control tube, a sealing ring disposed on the side of the chamber door opposite to the curing chamber, and a plurality of sealing strips adapted to the partition plate fixedly installed on the side of the chamber door.

[0008] As a preferred embodiment of the present invention, an observation window is provided on the side of the box door.

[0009] As a preferred embodiment of the present invention, the placement assembly includes four positioning holes at the four corners of the top surface of the placement plate. Positioning rods are slidably installed on the inner walls of the positioning holes. Placement frames are fixedly installed on the top ends of the four positioning rods. A plurality of placement racks arranged in a linear array are fixedly installed on the inner walls of the placement frames. A plurality of evenly distributed ventilation openings are provided on the top surface of the placement plate. A plurality of sealing rubber plates corresponding to the ventilation openings are fixedly installed on the bottom surface of the placement racks. A top plate corresponding to the control assembly is fixedly installed at the end of the placement frame.

[0010] As a preferred embodiment of the present invention, two slots are symmetrically opened on the top and bottom surfaces of the end of the placement plate, and two connecting plates are symmetrically arranged at the ends of several placement plates. Several card plates that engage with the slots are fixedly installed on the side of the connecting plates.

[0011] As a preferred embodiment of the present invention, the sealing strip has two symmetrical relief openings on its side that are adapted to the connecting plate.

[0012] As a preferred embodiment of the present invention, the sealing assembly includes a plurality of sealing baffles corresponding to the communication ports slidably mounted on the top surface of the partition plate. A plurality of the sealing baffles located on both sides are fixedly connected by transmission rods. Transmission wedges are fixedly mounted at the ends of two transmission rods that are close to each other. Two fixing plates are symmetrically fixedly mounted on the top surface of the partition plate. A spring is fixedly mounted between the side of the fixing plate and the side of the transmission wedge. An installation rod is fixedly mounted on the partition plate at the position between the two transmission wedges. A driving wedge adapted to the transmission wedge is slidably mounted on the outer wall of the installation rod. A second spring is fitted onto the outer wall of the installation rod, and both ends of the second spring are fixedly connected to the partition plate and the driving wedge, respectively.

[0013] As a preferred embodiment of the present invention, the inclined surfaces of the transmission wedge and the driving wedge are in contact with each other and are slidably connected.

[0014] As a preferred embodiment of the present invention, the control component includes an installation port on the top surface of the placement plate and located directly above the drive wedge. The end of the placement plate has a through-hole communicating with the installation port. A spring telescopic rod is rotatably mounted on the inner wall of the installation port, and the telescopic end of the spring telescopic rod passes through the through-hole. An operating block is fixedly fitted on the outer wall of the installation port. Two limiting grooves are provided on the inner wall of the through-hole. A limiting block adapted to the limiting groove is fixedly mounted on the outer wall of the telescopic end of the spring telescopic rod.

[0015] As a preferred embodiment of the present invention, a knob is fixedly installed at the telescopic end of the spring telescopic rod.

[0016] The present invention has the following beneficial effects: 1. In this invention, the curing chamber is divided into multiple independent sealed chambers by a partition plate, a sealing baffle, and other structures. With the help of independent temperature control pipes and control valves, the temperature and humidity of each chamber can be precisely adjusted to meet the differentiated curing needs of concrete test blocks with different mix ratios and different uses. At the same time, the ventilation port of the placement plate and the chamber connection port can be opened simultaneously with the help of the control components, so that the independent chambers can be quickly connected into a whole space, which is suitable for the unified curing of large batches of test blocks. The two modes can be flexibly switched without the need to purchase multiple additional equipment, thus improving the applicability of the equipment. 2. In the initial state, multiple placement plates are linked together by connecting plates. The operator only needs to pull the connecting plate to bring out all the placement plates at the same time, reducing the operation steps of placing test blocks. When batch operation is required, pressing the elastic plate can release the linkage and realize the independent pulling of a single or part of the placement plates. This design takes into account the efficiency of batch operation and the flexibility of differentiated operation, reduces the labor intensity of the operator, and is especially suitable for multi-batch, small-batch test block curing scenarios. 3. In the independent chamber state, the door sealing strip, the body sealing ring and the sealing baffle form a multiple seal, reducing temperature and humidity exchange and lowering the energy consumption of the control system. When the chambers are connected, the linkage process of pulling, rotating and resetting the knob can simultaneously trigger the top plate to move up and the drive wedge to press down. The locking structure of the limit block and the limit groove can prevent the components from loosening. The overall design ensures a stable maintenance environment, while reducing the energy consumption of the equipment and improving the reliability and economy of use. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Example 1: This example shows the energy-saving concrete curing box test block placement assembly disclosed in this example, referring to... Figure 1-9The system includes a curing chamber 11 and a door 12 hinged to the opening of the curing chamber 11. Several partitions 13 arranged in a linear array are fixedly installed on the inner wall of the curing chamber 11. Several connecting openings 17 are opened on the top surface of the partitions 13. A guide rail 14 is fixedly installed on the inner wall of the curing chamber 11 directly above the partitions 13. A placement plate 15 is slidably installed on the inner wall of the guide rail 14. An observation window 16 is provided on the side of the door 12. A temperature control mechanism is provided on the inner wall of the curing chamber 11 directly above the several guide rails 14. A placement component for placing concrete test blocks is provided on the top surface of the placement plate 15. A sealing component for separating the enclosed space is provided on the top surface of the partitions 13. A control component for linking the placement component and the sealing component is provided on the side of the placement plate 15. The temperature control mechanism includes a temperature control tube 21 installed on the inner wall of the curing chamber 11, a control valve 22 installed on the temperature control tube 21, a sealing ring 23 installed on the side of the chamber door 12 opposite to the curing chamber 11, and several sealing strips 24 adapted to the partition plate 13 fixedly installed on the side of the chamber door 12.

[0021] The implementation principle of this embodiment is as follows: During use, the entire device is as follows: Figure 2As shown, the worker first opens the door 12 of the curing box 11, then applies a pulling force to the placement plate 15, causing it to slide smoothly along the pre-set guide rail 14 on the inner wall of the box to the outside. Then, concrete test blocks of different types and curing requirements are neatly placed on the placement components on the surface of the placement plate 15. After the test blocks are placed, the worker smoothly pushes the placement plate 15 back into the curing box 11. At this time, the placement plate 15 and the pre-set partition plate 13 inside the box are both in a closed state, and the entire internal space of the curing box 11 is divided into... Several independent sealed chambers are included. After the staff closes the door 12, the sealing strip 24 on the inside of the door 12 will tightly fit against the end face of the partition plate 13. At the same time, the sealing ring 23 on the edge of the chamber will completely cover the connection gap between the door 12 and the chamber. This double sealing structure can minimize the exchange of heat and humidity between the inside and outside of the chamber, ensuring the airtightness of each sealed chamber and the entire curing chamber 11, thereby effectively reducing the energy consumption of the temperature and humidity control system and achieving energy-saving effects. On this basis, the staff can control the curing chamber 11. The external control terminal adjusts the control valve 22 of the corresponding sealed chamber, thereby precisely controlling the heating power, cooling intensity, and atomization amount of the humidifier of each chamber's temperature control pipe 21. This allows for independent adjustment of the internal temperature, humidity, and other curing parameters of each sealed chamber, meeting the differentiated curing needs of concrete test blocks with different mix proportions and uses. The working principle and connection method of the temperature control pipe 21 are existing mature technologies and will not be elaborated further here. If a large batch of concrete test blocks with the same curing conditions need to be cured uniformly, after the test blocks are placed, the staff does not need to maintain the chamber separation state. They only need to use the control component to link the placement component and the sealing component to release the sealing structure on the partition plate 13 and the placement plate 15, opening the connecting channel between each chamber and allowing the internal space of the curing box 11 to be reintegrated into a whole. At this time, the temperature and humidity control system can set uniform parameters for the entire box space to achieve common curing of all concrete test blocks, avoiding the energy consumption of multiple systems operating separately, making it more energy-efficient and effective.

[0022] Example 2: Based on Example 1, this example discloses an energy-saving concrete curing box test block placement assembly, such as... Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the placement assembly includes four positioning holes 31 at the four corners of the top surface of the placement plate 15. Positioning rods 33 are slidably installed on the inner wall of the positioning holes 31. A placement frame 32 is fixedly installed on the top of the four positioning rods 33. A number of placement racks 34 arranged in a linear array are fixedly installed on the inner wall of the placement frame 32. A number of ventilation openings 36 are evenly distributed on the top surface of the placement plate 15. A number of sealing plates 35 corresponding to the ventilation openings 36 are fixedly installed on the bottom surface of the placement racks 34. A top plate 37 corresponding to the control assembly is fixedly installed at the end of the placement frame 32. Two slots 41 are symmetrically opened on the top and bottom surfaces of the end of the placement plate 15. Two connecting plates 42 are symmetrically arranged at the ends of several placement plates 15. Several clamping plates 43 that engage with the slots 41 are fixedly installed on the side of the connecting plates 42. Two clearance openings 25 that are adapted to the connecting plates 42 are symmetrically opened on the side of the sealing strip 24.

[0023] The implementation principle of this embodiment is as follows: In the initial state, several placement plates 15 inside the curing chamber 11 are linked together by a dedicated connecting plate 42. The integrally formed locking plate 43 on the surface of the connecting plate 42 precisely engages with the pre-set locking slot 41 at the end of each placement plate 15. The engagement structure is stable and not easy to loosen. This design allows the staff to open the chamber door 12 without pulling the placement plates 15 one by one. They only need to pull the connecting plate 42 to simultaneously drive all the placement plates 15 smoothly out along the guide rail 14 inside the chamber, reducing the operation steps of placing and removing test blocks and making it more convenient and efficient to use. If different test blocks need to be operated in batches or at different times during actual curing work, the staff can manually press the elastic locking plate 43 on the side of the connecting plate 42 to completely separate it from the locking slot 41 of the placement plate 15. Then, the connecting plate 42 can be removed as a whole to release the linkage state of all placement plates 15, enabling independent pulling of single or partial placement plates 15, which is flexible and adaptable. To meet differentiated operational needs, after successfully pulling the target placement plate 15 out of the curing box 11, the staff can neatly place the concrete test blocks to be cured on the placement rack 34 on the surface of the placement plate 15. After placement, the placement plate 15 is pushed back into the curing box 11, and the curing program can be started for standard curing. If it is necessary to connect the originally separated independent chambers in the curing box 11 to meet the needs of unified curing of a large number of test blocks, an upward push can be applied to the top plate 37 on the top of the placement rack 34 through the preset control components. Under the action of the push, the top plate 37 drives the placement frame 32 to slide upward along the positioning rod 33 and positioning hole 31 on the surface of the placement plate 15, thereby completely separating the sealing rubber plate 35 on the bottom surface of the placement rack 34 from the ventilation opening 36 on the surface of the placement plate 15. With the help of the connecting opening 17 between the chambers inside the box, all separated spaces are connected, so that the entire curing box 11 forms a unified constant temperature and humidity environment.

[0024] Example 3: Based on Example 1, this example discloses an energy-saving concrete curing box test block placement assembly, such as... Figure 6 and Figure 7 As shown, the sealing assembly includes several sealing baffles 51 slidably mounted on the top surface of the partition plate 13, corresponding to the communication port 17. Several sealing baffles 51 located on both sides are fixedly connected by transmission rods 52. Transmission wedges 53 are fixedly mounted on the ends of the two transmission rods 52 that are close to each other. Two fixing plates 54 are symmetrically fixedly mounted on the top surface of the partition plate 13. A spring 55 is fixedly mounted between the side of the fixing plate 54 and the side of the transmission wedge 53. An installation rod 56 is fixedly mounted on the partition plate 13 at the position between the two transmission wedges 53. A drive wedge 57 adapted to the transmission wedge 53 is slidably mounted on the outer wall of the installation rod 56. The inclined surfaces of the transmission wedge 53 and the drive wedge 57 are relatively close to each other and slidably connected. A second spring 58 is fitted on the outer wall of the installation rod 56, and the two ends of the second spring 58 are fixedly connected to the partition plate 13 and the drive wedge 57, respectively.

[0025] The implementation principle of this embodiment is as follows: When the curing chamber 11 is in a state of independent curing of each chamber, the pre-set connection port 17 between the chambers will be completely covered and blocked by the sealing baffle 51. The edge of the sealing baffle 51 is tightly fitted with the contact surface of the connection port 17, which can effectively block the air flow between different chambers, ensuring that the temperature and humidity parameters of each independent chamber are stable and controllable, and will not be disturbed by the airflow exchange between chambers; when it is necessary to connect the independent chambers to achieve unified curing of a large number of concrete test blocks, the pre-set control component can be activated. The control component drives the drive wedge 57 to slide downward along the mounting rod 56. During the sliding process, the drive wedge 57 will engage with the outer side of the mounting rod 56. Spring 55 compresses and stores energy. At the same time, the inclined surface of the drive wedge 57 abuts against the inclined surface of the transmission wedge 53 and generates a horizontal driving force, causing the transmission wedge 53 to slide smoothly along the horizontal guide rail 14. The transmission wedge 53 transmits power synchronously through the transmission rod 52 fixedly connected to it, pulling the sealing baffle 51 to move horizontally along the edge of the connecting port 17, and finally completely separating the sealing baffle 51 from the connecting port 17, thereby releasing the seal on the connecting port 17. Together with the previously opened ventilation port 36 of the placement plate 15, the originally independent chambers inside the maintenance box 11 are connected into a whole space to meet the needs of unified maintenance.

[0026] Example 4: Based on Example 1, this example discloses an energy-saving concrete curing box test block placement assembly, such as... Figure 7-9As shown, the control component includes a mounting port 61 on the top surface of the placement plate 15 and directly above the drive wedge block 57. The end of the placement plate 15 has a through-hole 62 communicating with the mounting port 61. A spring telescopic rod 63 is rotatably mounted on the inner wall of the mounting port 61, and the telescopic end of the spring telescopic rod 63 passes through the through-hole 62. An operating block 64 is fixedly fitted on the outer wall of the spring telescopic rod 63. Two limiting grooves 65 are provided on the inner wall of the through-hole 62. A limiting block 66 adapted to the limiting groove 65 is fixedly installed on the outer wall of the telescopic end of the spring telescopic rod 63. A knob 67 is fixedly installed on the telescopic end of the spring telescopic rod 63.

[0027] The implementation principle of this embodiment is as follows: When the control component is used to control the placement frame 32 and the drive wedge 57 in a coordinated manner, the device is in its initial state. The limiting block 66, which is integrally formed on the outer wall of the telescopic end of the spring telescopic rod 63, is embedded in the preset horizontal limiting groove 65. The operating block 64, which is fixedly connected to it, remains horizontally and statically placed in the installation port 61. It will not be displaced due to slight external vibration or accidental contact, ensuring that the initial position of the entire control component is stable and reliable. When it is necessary to perform the chamber connection operation, the operator first pulls the knob 67 outward, causing the spring telescopic rod 63 to extend synchronously, so that the limiting block 66 at the telescopic end is completely freed from the constraint of the horizontal limiting groove 65. Then, the knob 67 is rotated 90 degrees, and the torque transmission of the spring telescopic rod 63 causes the operating block 64 to rotate 90 degrees synchronously. During the rotation of the operating block 64, the protruding structures at both ends of the block will precisely abut against the top plate 37 of the placement frame 32 and the force-bearing end of the drive wedge 57, respectively, and apply a pushing force. This will simultaneously trigger the linkage action of the top plate 37 moving upward and the drive wedge 57 pressing downward, providing power for the subsequent opening of the chamber ventilation port 36 and the unsealing of the connecting port 17. After the operating block 64 has rotated to the correct position and completed the driving of the top plate 37 and the drive wedge 57, the operator releases the knob 67. Under the action of the spring telescopic rod 63's own rebound force, the telescopic end will drive the limit block 66 to automatically reset and precisely insert into the vertical limit groove 65, thereby locking the rotation angle of the spring telescopic rod 63 and the operating block 64, preventing them from loosening or returning to their original position during subsequent maintenance, and ensuring the stable operation of the entire device.

[0028] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
