Multi-layered stereoscopic curing frame for concrete blocks

Abstract

This utility model relates to a multi-layer three-dimensional curing frame for concrete blocks, including a gantry frame. A rope winding assembly is located at the top of the gantry frame, and the rope winding assembly is connected to at least three cables. The rope winding assembly can synchronously wind up or release the cables. Multiple frames are connected to the cables at intervals, and all connection points between the cables and the frames are not on a straight line. A detachable ventilation box with an open top is provided inside each frame, and a detachable ventilation base plate is provided at the bottom of each ventilation box. Multiple ventilation holes are provided on both the ventilation box and the ventilation base plate. This utility model effectively utilizes three-dimensional space while using the rope winding assembly to synchronously lift or lower the frames. Furthermore, because the ventilation boxes can be quickly detached from the frames, concrete blocks can be placed into the ventilation boxes, and then the ventilation boxes can be installed back into the frames, facilitating the placement of concrete blocks to higher levels of the curing frame.

Description

Technical Field

[0001] This utility model belongs to the technical field of concrete processing equipment, and specifically relates to a multi-layer three-dimensional curing frame for concrete blocks. Background Technology

[0002] Strict control of indoor temperature and humidity and the use of three-dimensional shelving for storage are crucial for ensuring the mechanical properties and durability of concrete blocks during curing. Maintaining a suitable temperature and humidity environment within the curing chamber promotes cement hydration through a dual mechanism: temperature accelerates the hydration process, increasing early strength, while humidity maintains the continuity of cementitious material hydration, preventing premature evaporation that leads to increased surface capillary porosity and cracking, and preventing the formation of a weak structural layer from incompletely hydrated cement particles. If curing conditions are inadequate, the blocks may exhibit problems such as large strength dispersion and increased carbonation depth, and may even develop shrinkage cracks during later use. Current technology uses multiple three-dimensional shelving units within the curing chamber to hold the concrete blocks. Each shelving unit consists of four pillars with multiple support plates at varying heights between them, each with ventilation holes. While this three-dimensional placement improves space utilization, it can be challenging to place concrete blocks on higher shelves. Utility Model Content

[0003] This utility model provides a multi-layer three-dimensional curing frame for concrete blocks, which is designed to facilitate the placement of concrete blocks on higher floors when the three-dimensional curing frame is high.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A multi-layer three-dimensional curing frame for concrete blocks includes a gantry frame. The top of the gantry frame is equipped with a rope winding assembly, which is connected to at least three cables. The rope winding assembly can simultaneously wind up or release the cables. Multiple frames are connected to the cables at intervals. All connection points between the cables and the frames are not on a straight line. A ventilation box with an open top is detachably provided inside the frame. A ventilation base plate is detachably provided at the bottom of the ventilation box. Multiple ventilation holes are provided on both the ventilation box and the ventilation base plate.

[0006] Furthermore, the rope winding assembly includes two rotating shafts mounted opposite each other on the gantry frame. Both ends of the rotating shafts are connected to the gantry frame via supports. Both sides of the rotating shafts are provided with winding wheels connected to the cable. Each of the rotating shafts is connected to a motor and a gear at both ends, and the other rotating shaft is provided with a gear at its end. The two gears mesh with each other.

[0007] Furthermore, the motor is a worm gear reducer motor mounted on a support.

[0008] Furthermore, there are four guide holes, each aligned with a reel, and the four cables are connected to the four corners of the frame.

[0009] Furthermore, the frame is movably fitted onto the ventilation box, the top of the ventilation box is provided with an upper protruding edge, and a handle is provided on the upper protruding edge.

[0010] Furthermore, a hook is connected to the handle via a safety rope, and a hanging ring matching the hook is provided on the lower surface of the ventilated base plate.

[0011] Furthermore, the lower edge of the ventilation box is provided with a lower convex edge, which is connected to the edge of the ventilation base plate by multiple sets of bolts and nuts.

[0012] Furthermore, the inner wall of the ventilation box and the upper surface of the ventilation base plate are provided with multiple protrusions.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The ventilation box is easy to assemble and disassemble from the frame, and the ventilation base plate can be disassembled and assembled from the bottom of the ventilation box, making it easy to place and remove the concrete blocks inside the frame.

[0015] 2. Removing the ventilation box from the frame can prevent the upper ventilation box from pressing on the lower ventilation box during descent, thus limiting the descent height of the ventilation box and making it inconvenient to pick up and put down the ventilation box.

[0016] 3. After placing the concrete blocks into the ventilation box, install the ventilation box into the frame. Use the rope winding assembly to wind up the cable at a predetermined distance, and then install the frame into the frame. This makes it easier to place the concrete blocks on the upper level of the curing frame. Attached Figure Description

[0021] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0022] See Figures 1 to 3 This utility model provides a multi-layer three-dimensional curing frame for concrete blocks, including a gantry frame 1. The two sides of the bottom of the gantry frame 1 are fixed to the ground by bolts. The top of the gantry frame 1 is provided with a rope winding assembly, which is connected to at least three cables 2. The rope winding assembly can simultaneously wind up or release the cables 2. Multiple frames 17 are connected to the cables 2 at equal intervals. The cables 2 are connected to the edges of the frames 17. The vertical projection of the frames 17 is a square frame structure. The connection points of the cables 2 and the frames 17 are not on a straight line, and the frames are nearly horizontal under the action of gravity. The frames 17 are detachably provided with a ventilation box 12 with an open top. The bottom of the ventilation box 12 is detachably provided with a ventilation base plate 15. Both the ventilation box 12 and the ventilation base plate 15 are provided with multiple ventilation holes 13, which is beneficial to improving the curing effect of the concrete blocks inside the ventilation box 12.

[0023] When placing concrete blocks onto the curing frame, first place the concrete blocks into the ventilation box 12, ensuring the blocks do not protrude above the upper edge of the box 12 to prevent them from falling out during lifting. Insert the ventilation box 12 into the frame 17, and simultaneously wind up multiple cables 2 at a predetermined distance (the distance between two adjacent frames 17) using a rope winding assembly. Then, insert the ventilation box 12 containing the concrete blocks into the lower frame 17, continuing this process until all frames 17 are filled. During this process, the frames 17 are continuously lifted, allowing workers to place the concrete blocks from a lower position, facilitating the placement of concrete blocks to higher levels of the curing frame.

[0024] Preferably, the rope winding assembly includes two rotating shafts 10 mounted opposite each other on the gantry frame 1. Each end of the rotating shaft 10 is connected to a support 7, which is fixedly mounted on the gantry frame 1. Both sides of the rotating shaft 10 are fixedly fitted with winding wheels 9, which are connected to the cable 2. The two ends of the front rotating shaft 10 are respectively fixedly connected to a motor 8 and a gear 11, and the end of the rear rotating shaft 10 is fixedly fitted with a gear 11. The two gears 11 mesh with each other.

[0025] When the motor 8 drives the front shaft 10 to rotate on the support 7, the two gears 11 mesh with each other, which can drive the other shaft 10 to rotate synchronously, and then drive the four winding wheels 9 to rotate synchronously, so as to realize the synchronous winding or release of the four cables 2, so that when the frame 17 is raised or lowered, the frame 17 can be kept in a near-horizontal state.

[0026] Preferably, the motor 8 is a worm gear reducer motor 8 mounted on the support 7. By utilizing the large reduction ratio of the worm gear, the output shaft of the motor 8 can be locked when the motor 8 is powered off or stops working, so as to prevent the winding wheel 9 from rotating and releasing the cable 2 under the action of heavy objects.

[0027] Preferably, there are four guide holes 6, which are aligned with each reel 9. The four cables 2 are connected to the four corners of the frame 17, which helps to balance the force on the frame 17 and prevents the frame 17 from tilting excessively to one side under the action of heavy objects, causing the concrete blocks to fall out of the ventilation box 12.

[0028] Preferably, the frame 17 is movably fitted onto the ventilation box 12. The top of the ventilation box 12 is provided with an upper protruding edge 18. When the ventilation box 12 is inserted into the frame 17, the upper protruding edge 18 is used to lock onto the upper surface of the frame 17 to quickly complete the installation. The upper protruding edge 18 is provided with a U-shaped handle 16. The function of the handle 16 is to facilitate the lifting of the ventilation box 12 by a forklift, crane or manual labor and then insert it into the frame 17.

[0029] Preferably, a hook 4 is connected to the handle 16 via a safety rope 3, and a hanging ring 5 matching the hook 4 is fixed on the lower surface of the ventilated base plate 15. The length of the safety rope 3 is slightly longer than the distance between two adjacent frames 17, which makes it convenient for the hook 4 to be hooked into the hanging ring 5. This can provide auxiliary load-bearing in case a cable 2 breaks, thus improving safety.

[0030] Preferably, the lower edge of the ventilation box 12 is provided with a lower protruding edge 14, which is connected to the edge of the ventilation base plate 15 by multiple sets of bolts and nuts. Specifically, bolts are fixedly inserted on the ventilation base plate 15, and through holes with an inner diameter larger than the outer diameter of the bolt shank are provided on the protruding edge 14. When the nuts are removed from the bolts, the ventilation box 12 can be lifted and the concrete blocks can be left on the ventilation base plate 15. The concrete blocks are first placed on the ventilation base plate 15, and then the ventilation box 12 is inserted so that the bolts pass through the through holes for connection. After the nuts are installed on the bolts, the connection is completed, which makes it more convenient to place or remove heavy concrete blocks.

[0031] Preferably, the inner wall of the ventilation box 12 and the upper surface of the ventilation base plate 15 are provided with multiple protrusions 19, which can prevent the concrete blocks inside the ventilation box 12 from sticking to the inner wall of the ventilation box 12 and affecting the ventilation effect of the concrete blocks.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
