Description

Technical Field

[0001] This invention relates to the field of concrete curing technology, and more specifically, to a humidity control device for curing solid waste-based ecological concrete. Background Technology

[0002] Solid waste-based eco-concrete is an environmentally friendly type of concrete that uses industrial solid waste (such as slag and fly ash) as the main cementitious material or aggregate. During its hardening and strength development, it is sensitive to the humidity of the curing environment and needs to be maintained within a suitable humidity range over a long period to ensure sufficient hydration reaction and achieve the desired mechanical properties and durability. Therefore, precise and stable humidity control is a key aspect of its curing process.

[0003] Currently, for laboratory or small-batch curing of such concrete test blocks, sealed curing chambers or standard curing rooms are commonly used. Existing curing equipment generally has the following shortcomings:

[0004] 1. Traditional curing chambers typically use overall humidification, making it difficult to control humidity in different zones for test blocks with different formulations, ages, or curing requirements. Poor uniformity of the humidity field within the chamber can lead to inconsistent curing conditions for the test blocks, affecting the accuracy and comparability of experimental results.

[0005] 2. The shelves inside the curing chamber are mostly fixed structures with non-adjustable shelf heights, making it impossible to accommodate test blocks of different sizes and resulting in low space utilization. Accessing test blocks often requires opening the entire chamber, disrupting the stable humidity environment inside, leading to a long recovery period and affecting the continuity of curing.

[0006] 3. The placement and removal of test blocks mostly rely on manual operation. Manual placement and removal of test blocks, especially when stored in multiple layers, is not only laborious, but also poses a risk of injuring the test blocks or the operator.

[0007] Therefore, it is necessary to improve existing technologies. Summary of the Invention

[0008] To overcome the shortcomings of existing technologies, a solid waste-based ecological concrete curing device is provided that can achieve precise humidity control by zone, flexible and adjustable space, automated pick-up and drop operations, and minimize disturbance to the curing environment.

[0009] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0010] A humidity control device for curing solid waste-based ecological concrete includes a curing box, a pick-and-place rack, and a humidity control system. The curing box is open at one end, the pick-and-place rack is set at the open end of the curing box and can close the opening, and the humidity control system is used to control the humidity inside the curing box.

The upper surface of the support plate is provided with a sinking platform for translating and limiting the bearing plate.

[0012] The humidity control system includes a partitioning mechanism, a humidifier, and a humidification main pipe connected to the humidifier. The partitioning mechanism includes a longitudinal shielding mechanism and several lateral shielding mechanisms that can be unfolded and retracted. The lateral shielding mechanisms are arranged between adjacent placement racks, and the longitudinal shielding mechanisms are arranged at the open end of the curing box. When the lateral shielding mechanisms are unfolded to contact the longitudinal shielding mechanisms, the curing box is divided into at least two independent spaces distributed vertically.

[0013] Humidification branch pipes are installed between two adjacent transverse shielding mechanisms. Each humidification branch pipe is connected to the main humidification pipe, and each humidification branch pipe is equipped with a quick switch to control its on / off state.

[0014] Preferably, the pick-and-place rack includes a pick-and-place base, a pick-and-place stand, a slide, and a pick-and-place plate. The pick-and-place base is fixedly connected to the curing box. A horizontal guide rail is slidably arranged on the pick-and-place base. The pick-and-place stand is slidably arranged on the horizontal guide rail and can fit against the open end of the curing box. A linear actuator is provided on the pick-and-place base to drive the pick-and-place stand to slide along the horizontal guide rail. The slide is slidably arranged on the pick-and-place stand in the vertical direction. A slide drive mechanism is provided on the pick-and-place stand.

[0015] The slide is equipped with a horizontal guide groove, and the pick-and-place plate is slidably mounted on the horizontal guide groove.

One end of the trigger rod contacts the movable end of the scissor lift frame, and the other end of the trigger rod extends out of the base plate. A stop block that works in conjunction with the trigger rod is installed inside the curing box.

[0018] Preferably, the longitudinal shielding mechanism includes a second drum, a second pull rod, a third drum, and a third pull rod. The second drum and the third drum are rotatably mounted at the upper and lower ends of the curing box and are connected to an automatic return mechanism. A film is wound on the second drum and the third drum, and the second pull rod and the third pull rod are respectively connected to the ends of the film wound on the second drum and the third drum.

[0019] Preferably, a sliding seat is slidably provided on the maintenance box along the vertical direction, and the second and third pull rods are respectively provided at the upper and lower ends of the sliding seat and fixedly connected to the sliding seat, with a gap between the second and third pull rods;

[0020] The curing box is equipped with a linear motion driver II that drives the sliding seat to move up and down; the side wall of the curing box is equipped with a positioning sensor that detects whether the sliding seat has moved to the target position.

[0021] Preferably, the lateral shielding mechanism includes a first roll and a first pull rod. A back plate is sealed inside the curing box. The first roll and the first pull rod are located on both sides of the back plate. A film is wound on the first roll, and the film passes through the back plate and is fixedly connected to the first pull rod. The first roll is rotatably mounted on the curing box and is connected to an automatic return mechanism.

[0022] The maintenance box is slidably connected to a traction rod on its side wall. Several electromagnetic rods are installed on the traction rod. Each electromagnetic rod corresponds to a first pull rod of a horizontal shielding mechanism. When the electromagnetic rods cooperate with the first pull rods, the first pull rods move synchronously with the traction rod.

[0023] Preferably, the traction rod is connected to a linear motion driver I that drives it to move horizontally along the maintenance box, the linear motion driver I is connected to a controller, and the electromagnetic rods are all electrically connected to the controller;

[0024] Both the second and third pull rods are provided with slots. When the linear motion driver I drives the traction rod to move toward the opening end of the maintenance box, the first pull rod is inserted into the slot of the second or third pull rod.

[0025] Preferably, the support plate is fixedly connected to a control rod and rotatably connected to the curing box via the control rod. The upper side wall of the control rod is provided with a guide groove, which includes a first straight segment, a spiral segment, and a second straight segment connected in sequence.

[0026] The rotation control mechanism includes a control slider that is slidably disposed on the side wall of the curing box in a horizontal direction, and a drive rod that can be inserted into a guide groove is fixedly connected to the control slider; when the drive rod is engaged with the first straight segment, the support plate is in a horizontal state; when the drive rod is engaged with the second straight segment, the support plate is in a vertical state; when the drive rod is engaged with the spiral segment, the support plate is in an inclined state.

[0027] Preferably, the pick-and-place plate is connected to a mounting block via a linear motion driver III. The mounting block is equipped with a telescopic rod that cooperates with the control slider. The telescopic rod is equipped with an electromagnetic push rod that controls its extension and retraction.

[0028] A force sensor is installed on the telescopic rod.

[0029] Preferably, the upper end of the pick-and-place base is provided with a limiting block that cooperates with the pick-and-place plate, and the lower end of the pick-and-place stand is provided with a through hole through which the pick-and-place plate can pass.

[0030] The beneficial effects of this invention compared to the prior art are as follows:

[0031] 1. This invention, by setting up a partitioning system consisting of a transverse shielding mechanism and a longitudinal shielding mechanism, combined with independent branch pipes and quick switches, can divide the internal space of the curing chamber into multiple independent curing units. Based on feedback data from humidity sensors in each unit, the controller independently controls the humidification of the corresponding branch pipes, achieving differentiated and precise humidity curing of test blocks in different areas, greatly improving the accuracy and uniformity of humidity control.

[0032] 2. The placement rack of this invention adopts a support plate design that can be folded down to a vertical position. When it is necessary to cure taller test blocks, the upper unused support plate can be folded up to free up vertical space. This design allows the same curing box to adapt to the curing needs of test blocks of different sizes, improving the versatility of the equipment and space utilization.

[0033] 3. This invention achieves automatic gripping, lifting, transporting, and placement of the bearing plate (along with the test block) through the cooperation of the pick-and-place frame and the carriage drive mechanism. The pick-and-place frame can close the curing chamber opening when not in operation, and the curing chamber only opens the minimum necessary channel (the channel between the second and third pull rods) during pick-and-place operations, thus maintaining the stability of the humidity environment inside the chamber to the greatest extent.

[0034] 4. This invention utilizes the cooperation between the trigger rod and the abutment block on the back plate to achieve automatic lifting of the lifting plate during the picking and placing process, so that the bearing plate is separated from the support plate; combined with the state switching control of the support plate, it ensures that the entry and exit height of the picking and placing plate is consistent when picking and placing test blocks at the same position, effectively avoiding accidental collisions caused by height changes, and ensuring safe and smooth operation.

Detailed Implementation

[0051] 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.

[0052] like Figure 1 , Figure 2 As shown, the solid waste-based ecological concrete curing humidity control device includes a curing box 1, a pick-and-place rack 2, and a humidity control system 3. The curing box 1 has an opening on one side for placing and removing solid waste-based ecological concrete test blocks 5. The pick-and-place rack 2 is located on the opening side of the curing box 1 and can close the opening, keeping the curing box 1 closed when no pick-and-place operations are being performed. The humidity control system 3 regulates the humidity inside the curing box 1, ensuring that the solid waste-based ecological concrete test blocks 5 are maintained within a suitable humidity range during curing.

[0053] In this embodiment, as Figure 9 As shown, the solid waste-based ecological concrete test block 5 to be cured is placed on the support plate 4. When the pick-up and drop rack 2 picks up and drops the solid waste-based ecological concrete test block 5, it picks up and drops the support plate 4 together.

[0054] The maintenance box 1 has several racks arranged from top to bottom. Preferably, the spacing between adjacent racks is the same to facilitate the programmed operation of picking up and placing the racks 2. Each rack includes two symmetrically arranged support plates 11. When both support plates 11 are in a horizontal state, the support plate 4 can be placed between the two support plates 11. The support plates 11 are provided with a sunken platform 111 that is adapted to the support plate 4 to prevent the support plate 4 from accidentally slipping.

[0055] When the placement rack is not in use, the support plate 11 can be folded down to a vertical position, increasing the height of the space above the lower support plate 11, so that a taller solid waste-based ecological concrete test block 5 can be placed on the lower support plate 11.

[0056] like Figures 2 to 5 , Figure 13 As shown, each support plate 11 is fixedly connected to a control rod 112. The support plate 11 is set inside the curing box 1 through the control rod 112. The control rod 112 is set horizontally and rotates with the curing box 1. The side wall of the control rod 112 is provided with three connected guide grooves, including a first straight section 113, a spiral section 114 and a second straight section 115. Preferably, the spiral angle of the spiral section 114 is 90°.

[0057] To control the rotation of the support plates 11, each support plate 11 is connected to a rotation control mechanism 12 that controls its rotation to a horizontal or vertical state. Specifically, the rotation control mechanism 12 includes a control slider 121 that slides horizontally along the side wall of the curing box 1. A drive rod 122 is fixedly connected to the control slider 121, and the end of the drive rod 122 is inserted into a guide groove and slides in cooperation with the guide groove. When the drive rod 122 engages with the first straight section 113 of the guide groove, the support plate 11 is in a horizontal state; when the drive rod 122 engages with the second straight section 115 of the guide groove, the support plate 11 is in a vertical state; and when the drive rod 122 engages with the spiral section 114, the support plate 11 is in an inclined state.

[0058] Solid waste-based ecological concrete test block 5 requires a stable humidity environment for curing. To facilitate humidity control in curing chamber 1, such as... Figure 12 As shown, in this embodiment, the humidity control system 3 includes a humidifier 31, a partitioning mechanism, a main humidification pipe 32, and branch humidification pipes 35. The humidifier 31 can be an existing industrial humidifier. The partitioning mechanism is used to spatially separate the solid waste-based ecological concrete test blocks 5 on different placement racks, enabling the humidity control system 3 to individually control the humidity of certain spaces. The main humidification pipe 32 is connected to the humidifier 31. Multiple branch humidification pipes 35 are provided. One end of each branch humidification pipe 35 is connected to the main humidification pipe 32, and the other end is connected to the space where each placement rack is located. A quick switch 36 is provided on each branch humidification pipe 35 to control its on / off state.

[0059] like Figures 7 to 11 As shown, the partitioning mechanism includes a back plate 17, a lateral shielding mechanism, and a longitudinal shielding mechanism. The back plate 17 is fixedly installed at the end of the curing box 1 away from the opening and is sealed to the side wall of the curing box 1.

[0060] The lateral shielding mechanism includes a first drum 341 and a first pull rod 342. The first drum 341 is rotatably mounted on the curing box 1 and connected to an automatic return mechanism 335. Specifically, the curing box 1 is provided with a first mounting shaft, and the first drum 341 is rotatably mounted on the first mounting shaft. A film 336 is wound on the first drum 341, and one end of the film 336 is fixedly connected to the first pull rod 342. A horizontal groove is provided on the side wall of the curing box 1, and both ends of the first pull rod 342 slide in cooperation with the corresponding horizontal grooves on the side wall. The first drum 341 and the first pull rod 342 are located on both sides of the back plate 17. The back plate 17 is provided with narrow holes for the film 336 to pass through, and by providing narrow holes, the airflow speed can be slowed down.

[0061] The automatic return mechanism 335 uses a spring. The spring is located between the first drum 341 and the mounting shaft. When the first pull rod 342 is not pulled by an external force, the first drum 341 rotates in the opposite direction under the action of the spring, and the film 336 is wound around the first drum 341.

[0062] Multiple horizontal shielding mechanisms are provided from top to bottom. Preferably, there is one horizontal shielding mechanism between adjacent placement racks, so that the humidity control system can physically separate the solid waste-based ecological concrete test blocks 5 on each placement rack.

[0063] To drive the first pull rods 342 of the multiple lateral shielding mechanisms, a vertically placed traction rod 18 is provided on the side wall of the curing box 1. The traction rod 18 slides in cooperation with the side wall of the curing box 1. Multiple electromagnetic insertion rods 181 are arranged from top to bottom on the traction rod 18. Each electromagnetic insertion rod 181 corresponds one-to-one with a first pull rod 342 of the multiple lateral shielding mechanisms. The end of the first pull rod 342 near the traction rod 18 is provided with an insertion hole for the electromagnetic insertion rod 181 to be inserted. Preferably, the traction rod 18 is located on the outside of the curing box 1. The side wall of the curing box 1 is provided with multiple transverse grooves for the electromagnetic insertion rods 181 to be inserted and move horizontally. When several electromagnetic insertion rods 181 are inserted into the corresponding first pull rods 342, by controlling the horizontal movement of the traction rod 18, the corresponding first pull rods 342 can be moved, thereby causing the corresponding covering film 336 to unfold and divide the space inside the curing box 1.

[0064] To improve the separation effect of the membrane, a rubber baffle 37 is fixedly installed on the inner side wall of the curing box. The rubber baffle 37 contacts the edge of the membrane, improving the sealing effect between the membrane and the side wall of the curing box 1. Preferably, a waterproof geomembrane can be used for the membrane. To improve the tensile strength of the geomembrane, tensile material can be pasted on the edge of the geomembrane to prevent the membrane from deforming during the pulling process of the first tie rod 342, which would affect the cooperation effect between the membrane and the rubber baffle 37.

[0065] The traction rod 18 is connected to a linear motion driver I 182 for driving it to slide along the maintenance box 1. Preferably, the linear motion driver I 182 is a linear motor, which is connected to a controller. Several electromagnetic plug rods 181 are electrically connected to the controller, which can be an existing PLC controller.

[0066] When it is necessary to move a certain first pull rod 342, the controller controls the corresponding electromagnetic plug 181 to extend and insert into the socket of the first pull rod 342, and then controls the linear motion driver I 182 to work, thereby moving the first pull rod 342 by moving the traction rod 18. The controller's control of the extension and retraction of the electromagnetic plug 181 and the control of the motor are existing technologies and will not be described in detail here.

[0067] To reduce airflow at the transverse groove of the curing box 1, a closed sheet 38 that can move with the traction rod 18 is provided on the outside of the transverse groove. The outer wall of the curing box 1 is provided with a transverse groove 381, and the closed sheet 38 is slidably disposed in the transverse groove 381. When the traction rod 18 moves, the closed sheet 38 is always in contact with the transverse groove 381. Preferably, the closed sheet 38 adopts a ring structure and is made of rubber material.

[0068] The longitudinal shielding mechanism includes a second drum 331, a second pull rod 332, a third drum 333, and a third pull rod 334. The second drum 331 and the third drum 333 are respectively disposed at the upper and lower ends of the opening side of the curing chamber 1 and are connected to an automatic return mechanism 335. Preferably, the automatic return mechanism 335 is a spring-loaded mechanism. The curing chamber 1 is provided with a second mounting shaft and a third mounting shaft. The second drum 331 is rotatably coupled with the second mounting shaft and is provided with a spring-loaded mechanism, and the third drum 333 is rotatably coupled with the third mounting shaft and is provided with a spring-loaded mechanism.

[0069] Both the second roll 331 and the third roll 333 are wound with a film 336. The ends of the film 336 are fixedly connected to the second pull rod 332 and the third pull rod 334, respectively. By moving the second pull rod 332 or the third pull rod 334, the corresponding film 336 can be unfolded or retracted. The side wall of the curing box 1 is provided with a rubber baffle that matches the edge of the film 336.

[0070] Preferably, the distance between the second pull rod 332 and the third pull rod 334 is an integer multiple of the spacing between adjacent placement racks. Specifically, the second pull rod 332 and the third pull rod 334 are fixedly connected by a sliding seat 14, which is slidably mounted on the curing box 1 in the vertical direction. The sliding seat 14 is connected to a linear motion driver II 15 that drives it to slide along the curing box 1. The linear motion driver II 15 can be a synchronous belt mechanism, a chain drive mechanism, a linear motor, or other drive mechanisms that can realize linear drive and position control. This embodiment uses a synchronous belt mechanism. Figure 1 , Figure 14 As shown, the sliding seat 14 can adopt a telescopic structure, so that the distance between the second tie rod 332 and the third tie rod 334 can be changed between one or two times the distance between adjacent placement frames, which can accommodate the placement and removal of solid waste-based ecological concrete test blocks 5 of different heights.

[0071] The synchronous belt mechanism is mounted on the curing box. One of the synchronous belt pulleys of the synchronous belt mechanism is connected to a drive motor, and the sliding seat 14 is fixedly connected to the synchronous belt of the synchronous belt mechanism. When the drive motor drives the synchronous belt to move, it synchronously drives the sliding seat 14 connected to the synchronous belt to move up and down, thereby adjusting the positions of the second pull rod 332 and the third pull rod 334.

[0072] The side wall of the curing box 1 is equipped with a positioning sensor 16 to detect whether the sliding seat 14 has moved to the target position. Specifically, an infrared positioning sensor is set for each space where the placement rack is located. When the infrared positioning sensor detects the sliding seat 14, it means that the opening space between the second pull rod 332 and the third pull rod 334 is exactly outside the placement rack corresponding to the infrared positioning sensor. At this time, the pick-and-place rack 2 can enter and exit the curing box 1 through the opening space to pick up and place the bearing plate 4.

[0073] Preferably, both the second pull rod 332 and the third pull rod 334 are provided with slots. When the first pull rod 342 is pulled to divide the space inside the curing box 1, the first pull rod 342 abuts against or is inserted into the slot with the membrane 336 of the longitudinal shielding mechanism. An independent space for accommodating the solid waste-based ecological concrete test block 5 is formed by the back plate 17, the side wall of the curing box 1, and the membranes 336 of the transverse and longitudinal shielding mechanisms.

[0074] Humidification branch pipe 35 passes through back panel 17 and can deliver humidified air into corresponding independent spaces. Each independent space is equipped with at least one humidity sensor, and the controller can control the opening and closing of quick switch 36 based on the data from the humidity sensor. The humidity of the independent space is dynamically adjusted by the controller through the control of quick switch 36.

[0075] The pick-and-place rack 2 includes a pick-and-place base 21, a pick-and-place stand 22, and a pick-and-place plate 24. The pick-and-place base 21 is fixedly connected to the lower end of the curing box 1. A horizontal guide rail is provided on the side wall of the pick-and-place base 21. The pick-and-place stand 22 is slidably mounted on the guide rail. When the pick-and-place stand 22 moves to contact the opening of the curing box 1, it can close the opening. A linear actuator 25 is provided between the pick-and-place stand 22 and the pick-and-place base 21.

[0076] A slide 23 is slidably mounted on the vertically oriented pick-and-place stand 22. A slide drive mechanism 26 is provided between the slide 23 and the pick-and-place stand 22. Specifically, the pick-and-place stand 22 is provided with a vertical slide rail, and the slide 23 is provided with a vertical slide groove that mates with the vertical slide rail. A lead screw is rotatably mounted on the pick-and-place stand 22, and the slide 23 is threadedly engaged with the lead screw. One end of the lead screw is connected to a servo motor. The servo motor drives the lead screw to rotate, thereby causing the slide 23 to move up and down.

[0077] The slide 23 is provided with a horizontal guide groove 231, and the pick-up and put-down plate 24 is slidably disposed on the horizontal guide groove 231. The slide 23 is provided with a limit rod 232, and the pick-up and put-down plate 24 is provided with two limit holes 233 that cooperate with the limit rod 232. When the limit rod 232 is inserted into one of the limit holes 233, the pick-up and put-down plate 24 is in its maximum extended state relative to the slide 23; when the limit rod 232 is inserted into the other limit hole 233, the pick-up and put-down plate 24 is in its minimum extended state relative to the slide 23. Preferably, the limit rod 232 is connected to an electromagnetic push rod, and its extension and retraction are controlled by the electromagnetic push rod.

[0078] The upper end of the pick-up and place base 21 is provided with a limiting block 27 that cooperates with the pick-up and place plate 24. When the pick-up and place plate 24 moves to cooperate with the limiting block 27, the pick-up and place plate 24 will not be able to move horizontally relative to the pick-up and place base 21. The lower end of the pick-up and place stand 22 is provided with a through hole 28 through which the pick-up and place plate 24 can pass.

[0079] When the pick-up and drop plate 24 removes the solid waste-based ecological concrete test block 5 from the curing box 1, the bearing plate 4 needs to be raised a certain distance in order to detach the bearing plate 4 from the sinking platform 111. In the prior art, this is usually achieved by using a carriage drive mechanism 26, but the carriage drive mechanism 26 needs to perform both large-stroke drive and small-stroke drive, which increases the control complexity of the drive mechanism.

[0080] like Figure 6 As shown, in this embodiment, the pick-up and place plate 24 includes a base plate 241 and a lifting plate 242 arranged in parallel. The base plate 241 and the lifting plate 242 are connected by a scissor lift frame 243. A trigger rod 244 is slidably disposed on the base plate 241. One end of the trigger rod 244 extends out of the base plate 241, and the other end of the trigger rod 244 contacts the movable end of the scissor lift frame 243. When the trigger rod 244 moves toward the scissor lift frame 243, it pushes the movable end of the scissor lift frame 243 to move, thereby driving the lifting plate 242 to rise and fall.

[0081] The back plate 17 is provided with a stop block 13 that cooperates with the trigger rod 244. When the pick-up and drop plate 24 moves to the position of the stop block 13, the trigger rod 244 contacts the stop block 13 and drives the lifting plate 242 to rise, thereby driving the bearing plate 4 to detach from the sinking platform 111 through the lifting plate 242.

[0082] In this embodiment, the scissor lift frame 243 includes two support rods hinged together in the middle. One support rod has its two ends hinged to the base plate 241 and the lifting plate 242, respectively, while the other support rod has its two ends slidably connected to the base plate 241 and the lifting plate 242 via sliders. With this configuration, during the lifting process where the abutment block 13 and the trigger rod 244 work together to lift the lifting plate 242, the horizontal displacement of the lifting plate 242 relative to the bearing plate 4 is negligible.

[0083] Preferably, in order to prevent the lifting plate 242 from being insufficient to fit against the base plate 241 under the action of gravity, an elastic element that applies a downward pulling force to the lifting plate 242 can be provided between the base plate 241 and the lifting plate 242.

[0084] When the pick-up and place plate 24 enters the curing box 1 to retrieve the solid waste-based ecological concrete test block 5, the support plate 11 is initially in a horizontal state. After the lifting plate 242 raises the bearing plate 4, the support plate 11 needs to be rotated downwards to a vertical state. This ensures that the pick-up and place plate 24 can maintain the same height during the withdrawal process as during the entry process.

[0085] When taking and placing solid waste-based ecological concrete test blocks 5 on the same placement rack, keep the solid waste-based ecological concrete test blocks 5 at the same height to prevent accidental collisions caused by the different heights of the take-up and place-down plates 24 each time they are taken and placed.

[0086] A mounting block 124 is connected to the carriage 23 via a linear motion driver Ⅲ 123, which can be a linear motor. The mounting block 124 is equipped with a telescopic rod 125 that cooperates with the control slider 121. The telescopic rod 125 is equipped with an electromagnetic push rod that controls its extension and retraction. The telescopic rod 125 is in a retracted state by default. When it is necessary to move the control slider 121, the electromagnetic push rod controls the telescopic rod 125 to extend, and the linear motion driver Ⅲ 123 drives the telescopic rod 125 to move, thereby pushing the control slider 121 to move. When the telescopic rod 125 is retracted, it does not contact the control slider 121 during the movement of the pick-up and drop-off plate 24.

[0087] Preferably, a force sensor is provided on the telescopic rod 125 to detect the resistance it experiences, and buffer pads that cooperate with the telescopic rod 125 are provided on both sides of the control slider 121. When the sensor detects that the resistance experienced by the telescopic rod 125 is significantly greater than the force required to push the control slider 121 to move, it indicates that the control slider 121 has reached its maximum or minimum stroke position. At this time, the telescopic rod 125 is retracted by the electromagnetic push rod, and no more force is applied to the control slider 121.

[0088] In this embodiment, the maximum stroke position and the minimum stroke position refer to the two endpoint positions of the control slider 121 sliding along the curing box 1.

[0089] Preferably, magnets are provided on the curing box 1 at both the maximum and minimum stroke positions of the control slider 121, and magnetic material that attracts the magnets is provided on the control slider 121 to prevent the solid waste-based ecological concrete test block 5 from falling due to accidental sliding of the control slider 121.

[0090] Working principle:

[0091] In the initial state, the pick-and-place frame 22 contacts the open end of the curing box 1 and closes the curing box 1. The pick-and-place plate 24 is located at the bottom of the pick-and-place frame 22 (i.e., the pick-and-place plate 24 is located on the pick-and-place base 21). The solid waste-based ecological concrete test block 5 to be cured is placed on the pick-and-place plate 24 manually or by handling machinery. The sliding seat 14 is moved to the position of an empty support plate 11 on a certain layer by the linear motion driver II 15, and the upper and lower horizontal shielding mechanisms 34 corresponding to the support plate 11 are opened by the traction rod 18. This ensures that when the curing box 1 is opened, only the space where the support plate 11 is located is exposed.

[0092] The linear actuator 25 drives the pick-and-place frame 22 to move away from the curing box 1, so that the pick-and-place plate 24 and the solid waste-based ecological concrete test block 5 are located between the pick-and-place frame 22 and the curing box 1; the slide drive mechanism 26 drives the slide 23 and the pick-and-place plate 24 and the solid waste-based ecological concrete test block 5 on it to move upward until the height of the solid waste-based ecological concrete test block 5 is slightly lower than the height of the corresponding support plate 11 in the horizontal state.

[0093] The linear actuator 25 drives the pick-and-place frame 22 to move in the opposite direction, sending the solid waste-based ecological concrete specimen 5 into the curing box 1. The trigger rod 244 contacts the stop block 13, causing the lifting plate 242 and the solid waste-based ecological concrete specimen 5 to rise. At this time, the height of the solid waste-based ecological concrete specimen 5 is slightly higher than the height of the corresponding support plate 11 in a horizontal state. The rotation control mechanism 12 drives the control rod 112 to rotate until the support plate 11 is in a horizontal state. The linear actuator 25 drives the pick-and-place frame 22 to move away from the curing box 1. At this time, the lifting plate 242 descends, and the solid waste-based ecological concrete specimen 5 is placed on the support plate 11.

[0094] The pick-and-place stand 22 continues to move until the pick-and-place plate 24 is completely removed from the curing box 1, thus realizing the storage of the solid waste-based ecological concrete test block 5.

[0095] The above description only illustrates the preferred embodiments of the present invention. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention, and all such changes should be included within the protection scope of the present invention.
