Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete test piece curing, in particular to a curing chamber for building solid waste concrete test pieces. BACKGROUND

[0002] The curing chamber for building solid waste concrete test pieces is a facility specially designed to provide a standard curing environment for recycled concrete test blocks. Its core function is to ensure accurate detection of test piece performance through constant temperature and humidity control. Concrete test pieces are kept moist in the curing chamber by regular liquid spraying. After curing, the strength of the concrete test pieces can be improved. For example, a concrete test piece curing chamber with publication number CN216181538U includes a curing chamber body, which is provided with a spraying mechanism and a cold air mechanism. The curing chamber body is internally placed with a placing rack. The curing chamber body is provided with an entrance and exit. The side of the entrance and exit of the curing chamber body is installed with two mutually parallel slide rails. Two slide rails are slidably installed with a door plate for shielding the entrance and exit. It has the effect of reducing the influence of opening and closing the door plate on the temperature and humidity inside the curing chamber body. For example, a concrete test piece curing chamber with publication number CN220561819U includes a curing chamber body. The curing chamber body is provided with a protection mechanism for placing external air. It also includes a closing mechanism for alternately opening and closing the protection mechanism. The first door plate is opened by the hydraulic rod through the hinge link and the connecting frame. The second door plate is closed by the reverse frame, which prevents too much external air from entering and affecting the curing and preservation of the entire concrete test piece. The movement of the first door plate and the second door plate drives the piston rod at the end of the T-shaped tube to move, so that when the first door plate and the second door plate are reset, the moving frame drives the piston rod to move to spray the water in the T-shaped tube, thereby changing the air humidity between the two door plates. However, the above-mentioned concrete test piece curing chamber still has the following shortcomings in actual use: 1. Since the concrete test piece needs to be placed in the curing chamber for a long time during curing, the concrete test piece is prone to adhere to the structure inside the curing chamber. Subsequent removal of the test piece is not convenient and may cause damage to the test piece. There is a lack of anti-adhesion structure to prevent the concrete test piece from adhering. 2. In addition, after the curing of the concrete test piece is completed, the surface debris will remain in the curing chamber, which needs to be cleaned manually, otherwise it will affect the stability of the test piece during subsequent curing. There is a lack of structure for automatically cleaning the inside of the curing chamber after curing.

[0003] In view of the above problems, it is urgent to make innovative design on the basis of the original concrete test piece curing chamber. SUMMARY

[0017] 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.

[0018] Please see Figures 1-10 The present invention provides the following technical solution: 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 10As 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.

[0019] 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 6-9 As 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.

[0020] 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 10 As 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.

[0021] 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.
