Description

Technical Field

[0001] This invention relates to the field of concrete specimen curing technology, specifically to a curing chamber for concrete specimens made from construction solid waste. Background Technology

[0002] A curing chamber for construction solid waste concrete specimens is a facility specifically designed to provide a standard curing environment for recycled concrete test blocks. Its core function is to ensure accurate testing of specimen performance through constant temperature and humidity control. Inside the curing chamber, concrete specimens are kept moist by periodically spraying liquid. After curing, this improves the strength of the concrete specimens. For example, a concrete specimen curing chamber with announcement number CN216181538U includes a curing chamber body equipped with a spraying mechanism and a cooling system. A shelf is placed inside the curing chamber body, and the body has an entrance and exit. Two parallel sliding rails are installed on one side of the curing chamber body with the entrance and exit, and a door panel is slidably installed between the two rails to block the entrance and exit. This reduces the impact of opening and closing the door panel on the temperature and humidity inside the curing chamber body.

[0003] For example, a concrete specimen curing chamber with announcement number CN220561819U includes a curing chamber body. The entrance of the curing chamber body is equipped with a protective mechanism to prevent external air from entering, and a closing mechanism for alternately opening and closing the protective mechanism. A hydraulic rod is used to open the first door panel via a hinged connecting rod and a connecting frame, and a reverse frame is used to close the second door panel, thus preventing excessive external air from entering and affecting the curing and preservation of the concrete specimen. The movement of the first and second door panels moves the piston rod at the end of the T-shaped tube. When the first and second door panels return to their original positions, the moving frame moves the piston rod to spray out water that has entered the T-shaped tube, thereby changing the air humidity between the two door panels. However, the above-mentioned concrete specimen curing chamber still has the following drawbacks in actual use:

[0004] 1. Because concrete specimens need to be placed in the curing room for a long time during curing, they are prone to sticking to the structure of the curing room. This makes it inconvenient to remove the specimens later and can easily cause them to break. There is a lack of anti-sticking structures to prevent concrete specimens from sticking together.

[0005] 2. Furthermore, after the concrete specimens have been cured, debris will remain on their surface in the curing chamber, requiring manual cleaning. Otherwise, it will affect the stability of the specimens during subsequent curing. There is a lack of a structure that automatically cleans the interior of the curing chamber after curing.

[0006] To address the aforementioned issues, there is an urgent need for innovative design based on the existing concrete specimen curing room. Summary of the Invention

[0007] The purpose of this invention is to provide a curing chamber for concrete specimens from construction solid waste, in order to solve the problems mentioned in the background art: traditional curing chambers lack anti-sticking structures to prevent concrete specimens from sticking together, and lack structures for automatic cleaning of the interior of the curing chamber after curing.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a curing chamber for concrete specimens from construction solid waste, comprising a curing box, wherein the front and back of the curing box are hinged with doors, and a servo motor is installed on the inner top surface of the curing box, wherein the output shaft of the servo motor is connected to a connecting shaft, and a bearing platform is sleeved on the upper end of the connecting shaft through a one-way bearing, wherein a separation mechanism is provided on the inner side of the bearing platform, and the separation mechanism is used to prevent the concrete specimen from sticking to the bearing platform;

[0009] It also includes: a water storage tank, fixed to the side of the maintenance box, the top of the water storage tank being connected to the other side via a water supply pipe and a fixing pipe, and the fixing pipe being fixed inside the maintenance box;

[0010] A cleaning mechanism is installed inside the maintenance box, and the cleaning mechanism is used to clean the debris remaining on the support platform.

[0011] Preferably, the separation mechanism includes a through hole at the edge of the support platform, and a movable cylinder passes through the inner side of the through hole. The bottom of the movable cylinder is open, and a reciprocating lead screw is fixed on the inner top surface of the movable cylinder.

[0012] Preferably, the lower end of the reciprocating lead screw and the support plate are threaded together, and the support plate is sleeved on the outside of the connecting shaft through a one-way bearing. The movable cylinder and the reciprocating lead screw are distributed at equal angles on the fixed plate, and the first tooth block is fixed at equal angles at the lower edge of the support plate.

[0013] Preferably, the first tooth block and the second tooth block are meshed together, and the second tooth block is set at equal angles on the fixed ring, and the fixed ring is fixed to the inner wall of the curing box. At the same time, the length of the second tooth block is equal to the lifting distance of the movable cylinder.

[0014] Preferably, the bottom of the fixed tube is provided with spray nozzles for curing at equal angles, and the fixed tube has a ring structure. The spray nozzles are located directly above the movable tube, and the liquid sprayed from the spray nozzles comes into contact with the concrete specimen to cure it.

[0015] Preferably, the cleaning mechanism includes a sleeve fitted on the outside of the connecting shaft via a one-way bearing, and a fixed disk is rotatably fitted on the outside of the sleeve. The fixed disk is fixed to the fixed pipe by a rod. Meanwhile, a brush rod is fixed on the side of the sleeve, and the bristles on the brush rod are in close contact with the surface of the support platform.

[0016] Preferably, the surface of the support platform is provided with a feeding channel, and the inside of the support platform is provided with a conveying channel. The conveying channel is interconnected with the inside of the fixed cylinder through a conveying pipe, and a one-way valve is provided inside the conveying pipe.

[0017] Preferably, a cam is fixedly sleeved on the lower end of the connecting shaft, and the edge of the cam slides in contact with one end of the guide rod. The guide rod passes through the fixed cylinder, and the cam can push the guide rod to move when it rotates.

[0018] Preferably, a piston block is fixed to the end of the guide rod away from the cam, and the guide rod and the fixed cylinder are elastically slidably connected. The fixed cylinder is fixedly inserted through the lower end of the curing box, and suction force can be generated by the movement of the piston block to suck up the material.

[0019] Compared with the prior art, the beneficial effects of the present invention are: the curing chamber for concrete specimens from construction solid waste is equipped with an anti-adhesion structure, which can prevent the concrete specimens from sticking together during long-term curing, thereby ensuring the integrity of the specimens. Furthermore, after curing, the residual debris in the curing chamber can be automatically and promptly cleaned to avoid affecting the subsequent curing of concrete specimens. The specific details are as follows:

[0020] 1. When the support platform drives the movable cylinder to rotate, the meshing transmission between the first tooth block and the second tooth block drives the movable cylinder and the reciprocating screw to rotate. Through the threaded transmission between the reciprocating screw and the support plate, the movable cylinder and the concrete specimen can be lifted, effectively preventing the concrete specimen from sticking to the movable cylinder and the support platform during the curing process.

[0021] Furthermore, because the second toothed block is longer, the two sets of toothed blocks can maintain meshing throughout the process of the moving cylinder rising;

[0022] 2. The connecting shaft drives the sleeve and brush rod to rotate, cleaning the debris remaining on the support platform. The debris can enter the conveying channel through the feeding channel. Then, the connecting shaft drives the cam to rotate, and pushes the piston block to move in the fixed cylinder through the guide rod. This generates suction in the fixed cylinder, sucking the debris in the conveying channel into the fixed cylinder through the conveying pipe. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-10 The present invention provides the following technical solution:

[0036] Example 1: To address the problems existing in the prior art, this example provides the following technical solution: a curing chamber for concrete specimens from construction solid waste, comprising a curing box 1, with hinged doors 2 on both the front and back of the curing box 1, and a servo motor 3 installed on the inner top surface of the curing box 1. The output shaft of the servo motor 3 is connected to a connecting shaft 4, and a support platform 5 is mounted on the upper end of the connecting shaft 4 via a one-way bearing. A separation mechanism is provided on the inner side of the support platform 5, and the separation mechanism is used to prevent the concrete specimen from being... The component is adhered to the support platform 5; it also includes: a water storage tank 13, fixed to the side of the curing box 1, the top of the water storage tank 13 being interconnected via a water supply pipe 14 and a fixing pipe 15, and the fixing pipe 15 being fixed inside the curing box 1; a cleaning mechanism, located inside the curing box 1, used to clean residual debris on the support platform 5; and a spray nozzle 16 for curing is provided at equal angles at the bottom of the fixing pipe 15, and the fixing pipe 15 has a ring structure, with the spray nozzle 16 positioned directly above the movable cylinder 7; such as Figures 1-3 and Figure 10 As shown, first open the box door 2, place the concrete specimen to be cured on the support platform 5, and let the bottom of the concrete specimen contact the top of the movable cylinder 7. Then close the box door 2, and the liquid in the water storage tank 13 is periodically transferred to the fixed pipe 15 through the water supply pipe 14, and finally sprayed on the concrete specimen through the spray nozzle 16 to keep it moist for curing.

[0037] Because concrete specimens need to be placed in the curing chamber for extended periods during curing, they are prone to sticking to the chamber's structure. This makes subsequent removal of the specimens inconvenient and increases the risk of breakage. The lack of anti-sticking structures to prevent this adhesion is a significant concern. Figures 3-4 and Figures 6-9As shown, the separation mechanism includes a through hole 6 at the edge of the support platform 5, and a movable cylinder 7 passes through the inner side of the through hole 6. The bottom of the movable cylinder 7 is open, and a reciprocating screw 8 is fixed to the inner top surface of the movable cylinder 7. The lower end of the reciprocating screw 8 is threadedly connected to the support plate 9, and the support plate 9 is sleeved on the outside of the connecting shaft 4 through a one-way bearing. The movable cylinder 7 and the reciprocating screw 8 are evenly distributed on the support plate 9, and a first tooth block 10 is fixed at an even angle at the lower edge of the support plate 9. The first tooth block 10 and the second tooth block 11 are meshed, and the second tooth block 11 is evenly set on the fixing ring 12, and the fixing ring 12 is fixed to the inner wall of the curing box 1. The length of the second tooth block 11 is equal to the lifting distance of the movable cylinder 7. When the concrete specimen is placed on the surface of the movable cylinder 7 and the support platform 5, in order to prevent the concrete specimen from sticking to the support platform 5 during the curing process, the connecting shaft 4 can be rotated by the operation of the servo motor 3, thereby rotating the support platform. The bearing platform 5 rotates synchronously with the support plate 9, causing the concrete specimen to rotate during the curing process. When the bearing platform 5 drives the movable cylinder 7 to rotate, the first tooth block 10 and the second tooth block 11 can mesh to drive the movable cylinder 7 and the reciprocating screw 8 to rotate. In this way, through the threaded transmission between the reciprocating screw 8 and the support plate 9, the movable cylinder 7 and the concrete specimen can be lifted, and the movable cylinder 7 and the concrete specimen will also rotate, effectively preventing the concrete specimen from sticking to the movable cylinder 7 and the bearing platform 5 during the curing process. Since the second tooth block 11 is relatively long, the meshing of the two sets of tooth blocks can be maintained during the lifting of the movable cylinder 7. Then, with the continuous drive of the servo motor 3, the movable cylinder 7 can be lowered through the threaded transmission between the reciprocating screw 8 and the support plate 9, allowing the concrete specimen to fit against the bearing platform 5 for continued curing. Since the connecting shaft 4 is connected to the bearing platform 5, the support plate 9 and the sleeve 18 through a one-way bearing, the sleeve 18 will not rotate when the servo motor 3 drives in one direction.

[0038] Example 2: After the concrete specimens have cured, debris remains on their surface in the curing chamber, requiring manual cleaning to ensure stability during subsequent curing. There is a lack of a structure for automatic cleaning of the curing chamber after curing. Therefore, this example addresses this issue through the following technical solution: Figures 4-7 and Figure 10As shown, the cleaning mechanism includes a sleeve 18 sleeved on the outside of the connecting shaft 4 via a one-way bearing, and a fixed disk 17 is rotatably sleeved on the outside of the sleeve 18. The fixed disk 17 is fixed to the fixed pipe 15 by a rod. A brush rod 19 is fixed to the side of the sleeve 18, and the bristles on the brush rod 19 are in close contact with the surface of the support platform 5. A feeding channel 20 is opened on the surface of the support platform 5, and a conveying channel 21 is provided inside the support platform 5. The conveying channel 21 is interconnected with the inside of the fixed cylinder 23 through a conveying pipe 22. A one-way valve is provided inside the conveying pipe 22. A cam 24 is fixedly sleeved on the lower end of the connecting shaft 4, and the edge of the cam 24 slides in contact with one end of the guide rod 25. The guide rod 25 passes through the fixed cylinder 23. A piston block 26 is fixed to the end of the guide rod 25 away from the cam 24. The guide rod 25 and the fixed cylinder 23 are elastically slidably connected, and the fixed cylinder 23 is fixedly inserted through the lower end of the curing box 1. After the concrete specimen is cured, it is taken out. At this time, the servo motor 3 drives the connecting shaft 4 to rotate in the reverse direction, while the bearing platform 5 and the support plate 9 remain stationary. This drives the sleeve 18 and the brush rod 19 to rotate. The brush rod 19 sweeps on the bearing platform 5 to clean the residual debris. As the brush rod 19 cleans, the debris can enter the conveying channel 21 through the feeding channel 20. The connecting shaft 4 can also drive the cam 24 to rotate and push the piston block 26 to move inside the fixed cylinder 23 through the guide rod 25. When the piston block 26 is no longer pushed, it automatically returns to its original position. In this way, a suction force is generated inside the fixed cylinder 23, which sucks the debris in the conveying channel 21 into the fixed cylinder 23 through the conveying pipe 22 for subsequent cleaning.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
