Description

Technical Field

[0001] This utility model relates to a production equipment for concrete blocks, specifically to a concrete steam curing mold and a conveying system using the mold. Background Technology

[0002] With technological advancements and increased environmental awareness, aerated concrete blocks (ACBs) have gradually replaced traditional red or blue bricks in recent years, becoming the preferred material for many large-scale civil engineering projects. Currently, the challenge facing manufacturers is how to improve the production efficiency and output of ACBs. In the production process of ACBs, after the concrete is mixed, it is poured into a moving mold frame, where it is shaped. The mold frame then transports the ACB to the next workstation for cutting, and finally to a pre-curing workshop for pre-curing. The applicant previously applied for a utility model patent (publication number CN208265202U) entitled "Aerated Concrete Moving Mold Frame Conveying Mechanism." This mechanism includes a moving mold frame and guide rails. The moving mold frame is equipped with wheels for traveling on the guide rails. A friction wheel drive mechanism, in conjunction with friction strips installed at the bottom of the moving mold frame, drives the moving mold frame to move. This drive method allows for more precise control of the moving mold frame's movement. However, this type of walking mold frame conveying mechanism is only suitable for unidirectional guide rail movement and cannot achieve the function of both lateral and longitudinal movement. For pre-curing workshops with multiple tracks, the existing technology can only transport the walking mold frame to the corresponding track by a shuttle car. The back-and-forth movement of the shuttle car not only affects the conveying efficiency but also increases the equipment investment cost. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, this utility model innovatively provides a concrete steam curing mold frame that can realize double-blade movement and a conveying system using the mold frame.

[0004] This concrete steam curing mold includes a frame body, with a transverse friction strip installed at the bottom of the frame body. The frame body is characterized by having two parallel transverse guide strips installed at its bottom, with the transverse friction strip located between the two guide strips and parallel to them. The frame body also has four longitudinally moving wheels installed at its bottom, with the lowest point of each wheel lower than the bottom surfaces of the guide strips and the transverse friction strips. The wheels are staggered from the transverse friction strips and the guide strips.

[0005] One side panel of the frame is a movable panel, and a bracket that can move to one side is installed on the frame. The bracket can support the movable panel, and the bracket is connected to a telescopic power source.

[0007] This conveying system includes guide rails, a friction wheel drive mechanism, and the aforementioned concrete curing mold frame. Multiple guide rails extend longitudinally, and the wheels of the concrete curing mold frame can move along the guide rails. The system is characterized by: a plurality of support wheel units arranged laterally in two rows at the front end of the guide rails; each support wheel unit includes a support wheel, a support wheel seat, and a power source for driving the support wheel up and down; a limiting flange is provided on the outer edge of the support wheel; each transverse guide bar of the concrete curing mold frame is arranged on a row of support wheels and located inside the limiting flange; the friction wheel drive mechanism includes a base, a friction wheel, a friction wheel power source, and a lifting cylinder; the friction wheel is driven by the friction wheel power source and mounted on a lifting seat; the lifting seat is mounted on the base and can move up and down; the lifting cylinder can drive the lifting seat to move up and down; and the friction wheel can contact the transverse friction bars.

[0008] A mold frame pushing mechanism is provided on one side of the guide rail. The mold frame pushing mechanism includes a chain, a sprocket, a pushing block, and a pushing power source. The chain is wound around the sprocket, and the pushing power source is connected to the sprocket for transmission. The chain is parallel to the guide rail, and the pushing block is connected to the chain. A force-receiving part is provided at the bottom of the frame, and the pushing block can act on the force-receiving part.

[0009] It includes a pre-curing workshop, which has multiple platforms. Each platform is equipped with guide rails, and the distance between two adjacent platforms is greater than the height of the concrete steam curing mold. A frame is provided at the front end of the guide rails, and a mold lifting device is installed on the frame. The mold lifting device can lift the concrete steam curing mold to each platform.

[0010] The frame lifting device includes a crane, a lifting frame, and two hook assemblies. The two hook assemblies are mounted on the lifting frame, which is movably mounted on the crane. The crane is longitudinally movable and mounted on the frame. The frame has hanging columns on both sides, and the two hook assemblies can hook onto the two hanging columns of the frame respectively.

[0011] The hook assembly includes a hook plate, a hook, and a hook power source. The hook plate has a hook groove, the hook is hinged to the hook plate, and the hook power source can drive the hook to rotate and lock the lifting column of the frame in the hook groove.

[0012] Two hanging columns are provided on each side of the frame; two hook slots are provided on the hook plate, and two hooks are hinged to the hook plate. A connecting rod is connected between the two hooks. One end of the connecting rod is hinged to one hook, and the other end of the connecting rod is hinged to the other hook.

[0022] like Figure 2 and Figure 3 As shown, this concrete steam curing mold includes a frame body 10, with a transverse friction strip 11 installed at the bottom of the frame body 10. Additionally, two parallel transverse guide strips 12 are installed at the bottom of the frame body 10. The transverse friction strip 11 is located between the two transverse guide strips 12, and the transverse friction strip 11 is parallel to the transverse guide strips 12. Figure 3As shown, four longitudinally moving wheels 13 are installed at the bottom of the frame 10. The lowest point of the wheels 13 is lower than the bottom surface of the transverse guide bar 12 and the bottom surface of the transverse friction bar 11 (when the wheels 13 move, they can prevent the guide rail 2 from interfering with the transverse guide bar 12 and the transverse friction bar 11). The wheels 13, the transverse friction bar 11, and the transverse guide bar 12 are all staggered from each other (e.g., Figure 3 As shown, the three are not on a straight line. When the transverse guide bar 12 moves on the support wheel 30, it can prevent the support wheel 30 from interfering with the traveling wheel 13. With this structure, the concrete curing mold frame moves longitudinally by moving on the support wheel 30 via the transverse guide bar 12, while the concrete curing mold frame moves longitudinally on the guide rail 2 via the traveling wheel 13. In this way, the concrete curing mold frame can achieve both longitudinal and transverse movement, eliminating the need for a shuttle car and significantly improving the conveying efficiency.

[0023] like Figure 2 and Figure 3 As shown, one side panel of the frame 10 is a movable plate 14. A bracket 15 that can move to one side is installed on the frame 10. The bracket 15 can support the movable plate 14 and is connected to a telescopic power source. After the movable plate 14 is opened, the block can be removed.

[0024] like Figure 3 As shown, a guide shaft 16 and a telescopic rod 18 are connected to the bracket 15, and a guide sleeve 17 is connected to the frame 10. The guide shaft 16 is axially movable within the guide sleeve 17, and the telescopic rod 18 is connected to a telescopic power source. Driven by the telescopic power source, the telescopic rod 18 moves the bracket 15, while the guide shaft 16 moves within the guide sleeve 17, guiding the bracket 15.

[0025] like Figure 1 As shown, this conveying system includes guide rails 2, a friction wheel drive mechanism 4, and a concrete curing mold 1. The guide rails 2 are multiple and extend longitudinally (there are two or more guide rails 2; one longitudinal conveying channel requires two guide rails 2, and multiple longitudinal conveying channels can be set). As mentioned above, the wheels 13 of the concrete curing mold 1 can move on the guide rails 2. Additionally, at the front end of the guide rails 2, there are several support wheel units 3 arranged laterally in two rows. Figure 5 As shown, the support wheel unit 3 includes a support wheel 30, a support wheel seat 31, and a support power source 32 for driving the support wheel 30 to move up and down. The support wheel 30 is mounted on the support wheel seat 31 via a sliding block, and the support power source 32 can drive the support wheel 30 to move up and down. A limiting flange 300 is provided on the outer edge of the support wheel 30. Each transverse guide bar 12 of the concrete curing mold frame 1 is arranged on a row of support wheels 30 and located inside the limiting flange 300 to prevent the transverse guide bar 12 from derailing. Figure 4 As shown, the friction wheel drive mechanism 4 includes a base 44, a friction wheel 40, a friction wheel power source 41, and a lifting cylinder 43. The friction wheel 40 is connected to the friction wheel power source 41 and is mounted on a lifting seat 42. The lifting seat 42 is mounted on the base 44 and can move up and down. The lifting cylinder 43 can drive the lifting seat 42 to move up and down, so that the friction wheel 40 can contact the transverse friction strip 11. The friction wheel 40 is driven to rotate by the friction wheel power source 41. The friction wheel 40 drives the concrete curing mold frame 1 to move laterally through the friction force acting on the transverse friction strip 11. When the concrete curing mold frame 1 moves laterally to the corresponding conveying channel, the support power source 32 can drive the support wheel 30 to move downward, putting the concrete curing mold frame 1 down. In this way, the traveling wheel 13 of the concrete curing mold frame 1 is placed on the guide rail 2 and can move longitudinally along the guide rail 2.

[0026] Each concrete steam curing mold 1 can be configured with a power source to drive longitudinal movement, but this is costly. To solve this problem, such as... Figure 1 and Figure 6 As shown, a mold frame pushing mechanism 7 is provided on one side of the guide rail 2. This mechanism includes a chain 71, a sprocket, a pushing block 70, and a pushing power source. The chain 71 is wound around the sprocket and is parallel to the guide rail 2. The pushing block 70 is connected to the chain 71. Figure 3 As shown, a force-receiving part 19 is provided at the bottom of the frame 10, and the push block 70 can act on the force-receiving part 19. During operation, the push power source drives the sprocket to rotate, so that the push block 70 on the chain 71 can act on the force-receiving part 19, thereby pushing the mold frame push mechanism 7 to achieve longitudinal movement.

[0027] In order to improve space utilization and enable large-scale pre-curing of blocks even in small spaces, such as Figure 1 As shown, the pre-curing workshop is equipped with multiple platforms 6, and each platform 6 is equipped with a guide rail 2. The distance between two adjacent platforms 6 is greater than the height of the concrete steam curing mold 1 (so that the concrete steam curing mold 1 can enter each platform 6). A frame 8 is provided at the front end of the guide rail 2, and a mold frame lifting device 5 is installed on the frame 8. The mold frame lifting device 5 is used to lift the concrete steam curing mold 1 onto each platform 6.

[0028] like Figure 7 As shown, the formwork lifting device 5 includes a traveling crane (not shown), a lifting frame 50, and two hook assemblies 51. The two hook assemblies 51 are mounted on the lifting frame 50, which is vertically and vertically mounted on the traveling crane. The traveling crane is longitudinally movable and mounted on the frame 8. Figure 2As shown, hanging columns 101 are provided on both sides of the frame 10, and two hook assemblies 51 can hook onto the two hanging columns 101 of the frame 10 respectively. After the hook assemblies 51 hook onto the hanging columns 101 of the frame 10, the lifting frame 50 lifts the frame 10 up. After reaching a certain platform 6, the trolley moves the lifting frame 50 and the frame 10 forward together. When it reaches the guide rail line 2 on the platform 6, the lifting frame 50 lowers the frame 10, allowing the wheels 13 of the frame 10 to be placed on the guide rail line 2. Through this structure, multi-layer block conveying and pre-curing can be realized. Under the same site area, the upper space can be significantly utilized, improving the site utilization rate.

[0029] like Figure 8 As shown, the hook assembly 51 includes a hook plate 510, a hook 512, and a hook power source 513. The hook plate 510 has a hook groove 511, and the hook 512 is hinged to the hook plate 510. The hook power source 513 can drive the hook 512 to rotate. When the lifting column 101 of the frame 10 enters the hook groove 511, the lifting column 101 of the frame 10 can be locked in the hook groove 511 by driving the hook 512 to rotate through the hook power source 513.

[0030] To improve stability, each side of the frame 10 is equipped with two lifting columns 101; the hook plate 510 has two corresponding hook slots 511, and two hooks 512 are hinged to the hook plate 510. A connecting rod 514 connects the two hooks 512, with one end of the connecting rod 514 hinged to one hook 512 and the other end hinged to the other hook 512. Driven by the hook power source 513, the two hooks 512 can rotate synchronously through the connecting rod 514, allowing the two lifting columns 101 on one side of the frame 10 to be locked in the two hook slots 511 respectively. With two lifting points on one side, the frame 10 is more stable when lifted, preventing swaying.

[0031] Finally, it is worth mentioning that all power sources involved in this application include, but are limited to, cylinders, hydraulic cylinders, electric actuators, and motors.
