Description

Technical Field

[0001] The present disclosure relates to the technical field of cement, and more particularly, to a cement specimen curing device. Background Art

[0002] In building materials, cement, as one of the most commonly used building cementitious materials, from the ex-factory inspection of the production plant to the type inspection after entering the site, all test indicators are related to the properties of the concrete mixture and the indicators after the concrete hardens. Among them, the mortar strength, as one of the most critical indicators, affects the quality and safety of the strength of the engineering entity.

[0003] To determine whether the strength of cement is qualified, the cement mortar strength test is mainly used. That is, according to the requirements of relevant regulations and specifications, the cement mortar strength test first needs to form prismatic cement mortar specimens indoors, undergo standard water curing for many days, and finally detect the strength value of the cement mortar specimens on a cement flexural and compressive testing machine. If the strength value meets the specification requirements, it is considered qualified.

[0004] During the test detection process, the cement specimens need to be placed in the small water tank of the curing box, and then water is manually added to the small water tank. After adding water, the small water tank is manually placed in the curing box for curing the cement specimens.

[0005] However, due to the large weights of the cement specimens, the small water tank, and the water, it is rather laborious for the staff to carry the small water tank with the cement specimens and water to the curing box, increasing the labor intensity of the staff.

[0006] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present disclosure, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Invention

[0007] The present disclosure provides a cement specimen curing device, which can reduce the labor intensity of the staff.

[0008] [[ID=地8]]A cement specimen curing device provided by the present disclosure includes:

[0009] A box body having a receiving cavity;

[0010] Multiple groups of support components, which are spaced apart along the length direction of the box body in the receiving cavity. Each group of support components includes a plurality of support frames spaced apart along the height direction of the box body in the receiving cavity. The support frame includes a frame body and a protrusion provided on the frame body. The frame body has a water injection channel, and the protrusion has a cavity, and the cavity is communicated with the water injection channel;

[0011] A placement box is placed on the support frame and is used to place cement test blocks. The placement box has a water injection hole that communicates with the inner cavity of the placement box. The protrusion can cooperate with the water injection hole so that the cavity communicates with the inner cavity of the placement box.

[0012] The water injection assembly includes a water injection pump, a water injection pipe, and a control panel. The water injection pipe is connected to the water injection channel. The water injection pump is located in the housing and is used to inject water into the water injection pipe. The control panel is used to control the start and stop of the water injection pump.

[0013] In one embodiment of this disclosure, the receiving cavity has a partition located between two adjacent sets of the support components and connected to the support frame.

[0014] In one embodiment of this disclosure, the water injection pipeline includes a first water injection pipe and a second water injection pipe that are connected in series.

[0015] The first water injection pipe is located inside the partition and extends along the height of the box, and the first water injection pipe is connected to the water injection channel.

[0016] A portion of the second water injection pipe is located inside the partition and extends out of the receiving cavity to communicate with the water injection pump.

[0017] In one embodiment of this disclosure, the cement test block curing device further includes a water injection tank;

[0018] The water injection pipeline also includes a third water injection pipe and a water injection valve;

[0019] One end of the third water injection pipe is located inside the water injection tank, and the other end is connected to the second water injection pipe through the water injection pump. The water injection valve is located on the third water injection pipe.

[0020] In one embodiment of this disclosure, a liquid level sensor is provided on the inner side wall of the placement box, and a control valve is provided on the frame. The control valve is used to control the opening and closing of the water injection channel, and the control panel is also used to control the opening and closing of the control valve according to the liquid level signal sent by the liquid level sensor.

[0021] In one embodiment of this disclosure, the frame includes a water injection rod and a plurality of support rods, the plurality of support rods being spaced apart along the width direction of the box, the water injection rod being located between two adjacent support rods, and the water injection channel, protrusion, and control valve being disposed on the water injection rod.

[0022] In one embodiment of this disclosure, the outer diameter of the protrusion gradually decreases in the direction away from the frame, and the diameter of the water injection hole gradually decreases in the direction away from the frame.

[0023] In one embodiment of this disclosure, a sealing ring is fitted around the outer periphery of the protrusion, and the sealing ring is located in the water injection hole.

[0024] In one embodiment of this disclosure, the water injection assembly includes a drain pipe and a drain valve. The drain pipe is connected to the water injection pump and the water injection pipeline, respectively. The drain valve is located on the drain pipe. The control panel is used to control the water injection and drainage of the water injection pump.

[0025] In one embodiment of this disclosure, the placement box is provided with a cushioning pad, and the cushioning pad exposes the water injection hole.

[0026] Workers can place cement test blocks into the placement boxes and then place the boxes, containing the cement test blocks, onto a support frame, ensuring the protrusion aligns with the water injection hole. The water injection pump is then activated via the control panel, allowing water from the injection pipe to enter the injection channel and finally flow from the cavity of the protrusion into the inner cavity of the placement box, thus achieving automatic water injection. Once the water level in the placement box reaches the required level, the control panel can shut off the water injection pump to stop water injection. Since there is no water in the placement boxes during the process of moving them onto the frame, the weight of the boxes is reduced, lowering the workload for workers. Furthermore, the water injection pump can simultaneously inject water into multiple placement boxes, improving water injection efficiency, saving manpower, facilitating the curing of cement test blocks, and enhancing the intelligence and automation of the cement test block curing device.

[0039] In this paper, the height, length, and width directions of box 1 are perpendicular to each other.

[0040] This disclosure provides a cement test block curing device, see [link to relevant documentation]. Figures 1-5 The cement test block curing device includes a box 1, a support assembly 2, a placement box 3, and a water injection assembly 4. The box 1 has a receiving cavity. Multiple sets of support assemblies 2 are spaced apart along the length of the box 1 within the receiving cavity. Each set of support assemblies 2 includes multiple support frames spaced apart along the height of the box 1 within the receiving cavity. Each support frame includes a frame body 21 and protrusions 22 on the frame body 21. The frame body 21 has a water injection channel, and the protrusions 22 have cavities that communicate with the water injection channel. The placement box 3 is placed on the support frames and is used to hold the cement test blocks. The placement box 3 has a water injection hole communicating with its inner cavity. The protrusions 22 can mate with the water injection hole to allow communication between the cavity and the inner cavity of the placement box 3. Water injection assembly 4 includes water injection pump 41, water injection pipe and control panel 42. The water injection pipe is connected to the water injection channel. The water injection pump 41 is located in the housing 1 and is used to inject water into the water injection pipe. The control panel 42 is used to control the opening and closing of the water injection pump 41.

[0041] In this way, workers can place cement test blocks into placement box 3 and place the placement box 3 with cement test blocks onto the support frame, so that the protrusion 22 aligns with the water injection hole. Then, the water injection pump 41 is activated via the control panel 42, allowing water from the water injection pipe to enter the water injection channel and finally flow from the cavity of the protrusion 22 into the inner cavity of the placement box 3, thus achieving the automatic water injection function in the placement box 3. When the water level in the placement box 3 reaches the required level, the control panel 42 can turn off the water injection pump 41 to stop water injection. Since there is no water in the placement box 3 during the process of moving the placement box 3 onto the frame 21, the weight of the placement box 3 is reduced, thus reducing the labor intensity of the workers. At the same time, the water injection pump 41 can inject water into multiple placement boxes 3 simultaneously, improving water injection efficiency, saving manpower, facilitating the curing of cement test blocks, and improving the intelligence and automation of the cement test block curing device.

[0042] In one embodiment of this disclosure, see Figure 1 The housing 1 may have a door 11, which can be hinged to the housing 1 to close the cavity and provide a suitable curing environment for the cement test blocks. The housing 1 may have temperature and humidity control functions to provide a suitable curing environment for the cement test blocks. The bottom of the housing 1 may have four support legs to separate the housing 1 from the ground, facilitating the transport of the cement test block curing device.

[0043] In one embodiment of this disclosure, see Figure 2 , Figure 3There are two sets of support components 2. The receiving cavity has a partition 5, which is located between two adjacent sets of support components 2 and connected to the support frame. The partition 5 can be fixedly connected to the top wall and side wall of the receiving cavity to separate two adjacent placement boxes 3.

[0044] In one embodiment of this disclosure, see Figure 3 , Figure 5 The water injection pipeline includes a first water injection pipe 43 and a second water injection pipe 44 that are connected. The first water injection pipe 43 is located inside the partition 5 and extends along the height of the housing 1, but does not penetrate the partition 5. The first water injection pipe 43 is connected to the water injection channel to facilitate water injection into the channel. Part of the second water injection pipe 44 is located inside the partition 5, with one end of the second water injection pipe 44 extending out of the receiving cavity and connecting to the water injection pump 41. Thus, water from the water injection pump 41 can flow into the water injection channel through the second water injection pipe 44 and the first water injection pipe 43, and finally flow into the placement box 3 through the cavity. By placing the first water injection pipe 43 and the second water injection pipe 44 within the partition 5, the space occupied by the first water injection pipe 43 and the second water injection pipe 44 is reduced, and the high structural strength of the partition 5 effectively protects the first water injection pipe 43 and the second water injection pipe 44.

[0045] In one embodiment of this disclosure, see Figure 3 , Figure 5 The cement test block curing device also includes a water injection tank 6, which contains curing water. The water injection pipeline also includes a third water injection pipe 45 and a water injection valve 46. One end of the third water injection pipe 45 is located inside the water injection tank 6, and the other end is connected to the second water injection pipe 44 via a water injection pump 41. The water injection valve 46 is connected to the third water injection pipe 45 via a flange. Thus, when the water injection pump 41 starts, the water injection valve 46 is opened, allowing the curing water in the water injection tank 6 to flow sequentially through the third water injection pipe 45 and the second water injection pipe 44 into the first water injection pipe 43, and finally into each water injection channel, facilitating water injection into the placement box 3.

[0046] In one embodiment of this disclosure, see Figure 1 , Figure 3 , Figure 4The inner wall of the placement box 3 is equipped with a liquid level sensor 31, and the frame 21 is equipped with a control valve 2111. The control valve 2111 is used to control the opening and closing of the water injection channel. The control panel 42 is also used to control the opening and closing of the control valve 2111 based on the liquid level signal sent by the liquid level sensor 31. For example, when the liquid level sensor 31 in a certain placement box 3 detects that the water level in the placement box 3 has reached the standard, it will send a liquid level signal to the control panel 42. After receiving the liquid level signal, the control panel 42 controls the control valve 2111 of this water injection channel to close, thereby cutting off the water supply in this placement box 3, improving the accuracy of water injection and avoiding unevenness caused by manual water injection. When the control panel 42 receives the liquid level signals from all the liquid level sensors 31, the control panel 42 will control the water injection pump 41 to shut down, thereby stopping water injection. By closing the control valve 2111, backflow of water in the placement box 3 can be prevented.

[0047] In one embodiment of this disclosure, see Figure 2 , Figure 3 , Figure 4 The frame 21 includes a water injection rod 211 and multiple support rods 212. The number of support rods 212 can be two, three, four, etc., and is not limited here. The multiple support rods 212 are spaced apart along the width direction of the housing 1 and located on the same plane. One end of each support rod 212 can be connected to the side wall of the receiving cavity, and the other end can be connected to the partition 5. The water injection rod 211 is located between two adjacent support rods 212. A water injection channel, a protrusion 22, and a control valve 2111 are provided on the water injection rod 211. One end of the water injection rod 211 can be connected to the side wall of the receiving cavity, and the other end can be connected to the partition 5. Thus, by using support rods 212 and water injection rods 211 to construct the frame 21, the weight of the frame 21 can be reduced, thereby reducing costs.

[0048] In one embodiment of this disclosure, see Figure 4 The protrusion 22 and the water injection hole are frustoconical, meaning the outer diameter of the protrusion 22 gradually decreases in the direction away from the frame 21, and the diameter of the water injection hole also gradually decreases in the direction away from the frame 21. On one hand, the protrusion 22, in conjunction with the water injection hole, facilitates the injection of water into the inner cavity of the placement box 3 while also providing positioning for the placement box 3, thus improving stability. On the other hand, the gradually changing outer diameter design of the protrusion 22 facilitates the separation of the placement box 3 from the protrusion 22.

[0049] In one embodiment of this disclosure, see Figure 4 The inner diameter of the cavity gradually decreases in the direction away from the frame 21. This prevents larger cement residues inside the placement box 3 from falling into the water injection channel through the cavity, reducing blockages in the water injection channel and improving reliability.

[0050] In one embodiment of this disclosure, the protrusion 22 can be threadedly connected to the water injection rod 211 to facilitate the disassembly of the protrusion 22 and to facilitate cleaning and maintenance when the cavity of the protrusion 22 is blocked.

[0051] In one embodiment of this disclosure, see Figure 4 A sealing ring 221 is fitted around the outer periphery of the protrusion 22. The number of sealing rings 221 can be one or more. The sealing ring 221 is fixedly connected to the protrusion 22 and is located within the water injection hole. Thus, through the design of the gradually changing diameter of the protrusion 22 and the water injection hole, during the engagement process, the wall of the water injection hole gradually comes into close contact with the sealing ring 221, improving the sealing performance and preventing water leakage from the water injection hole.

[0052] In one embodiment of this disclosure, see Figure 4 A buffer pad 32 is laid inside the placement box 3, with the water injection hole exposed. The buffer pad 32 can be a mesh structure to reduce the collision between the cement test block and the bottom of the placement box 3, thus maintaining the integrity of the cement test block.

[0053] In one embodiment of this disclosure, see Figure 3 , Figure 5 The water injection assembly 4 includes a drain pipe 47 and a drain valve 48. The drain pipe 47 is connected to the water injection pump 41 and the third water injection pipe 45 via a tee joint. The drain valve 48 is connected to the drain pipe 47 via a flange. The control panel 42 is used to control the water injection and drainage of the water injection pump 41. In one example, the water injection pump 41 can be a bidirectional pump, so that when the water injection pump 41 rotates forward, it injects water into the placement box 3, and when it rotates reverse, it drains water from the placement box 3. The outer wall of the housing 1 has a water injection button and a drain button. When the water injection button is pressed, the control panel 42 opens the water injection valve 46 and each control valve 2111, controls the water injection pump 41 to rotate forward, and closes the drain valve 48 to inject water into the placement box 3. When the drain button is pressed, the control panel 42 opens the drain valve 48 and each control valve 2111, controls the water injection pump 41 to rotate reverse, and closes the water injection valve 46 to drain water from the placement box 3. Thus, the water injection component 4 can achieve automatic water injection and drainage in the box 3, which facilitates the curing of cement test blocks and reduces the labor intensity of staff.

[0054] In one embodiment of this disclosure, see Figure 5 The cement test block curing device also includes a drainage box 7 to collect water placed in the box during the drainage process.

This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
