Description

Technical Field

[0001] The present application relates to the field of river management, and in particular to a prefabricated block lifting device. Background Art

[0002] The riverbed of the middle and lower reaches of the Yangtze River is composed of easily eroded fine sand and is covered with a thick layer. This causes dramatic riverbed changes and impacts navigation. To stabilize the riverbed, soft concrete rafts are one of the most commonly used methods. The Yangtze River's bottom protection is constructed using soft concrete rafts. The control of the laying trajectory, the overlap width of the rafts, and the inspection of the finished rafts have a significant impact on the construction quality and the effectiveness of the bottom protection. The soft concrete raft construction process includes construction preparation → layout optimization and processing → underwater topography survey → BIM-assisted layout trajectory design and meshing → layout vessel positioning → raft deployment → raft head beam lashing and lowering → prefabricated block transportation and lashing → raft body lowering, monitoring, and layout trajectory control → raft quality inspection → completion inspection.

[0003] In the prior art, before bundling the prefabricated blocks onto the arrangement, the operator will hoist multiple prefabricated blocks onto the arrangement as a whole, and then manually move a single prefabricated block to the installation position of the arrangement for bundling. Since the arrangement needs to be unfolded when the prefabricated blocks are bundled, the stacked multiple prefabricated blocks may be hoisted onto the arrangement as a whole, which may cause wear on the arrangement. At the same time, the operator needs to move the prefabricated blocks to the binding position multiple times, which is inefficient. Summary of the Invention

[0007] By adopting the above technical solution, the first drive assembly rotates the drive roller, which in turn causes the first conveyor belt to operate. An operator places a prefabricated block on the first conveyor belt, which moves along with the first conveyor belt. When a prefabricated block moves to the end of the loading chute, the control assembly stops the first conveyor belt at the end of the loading chute. When the second prefabricated block moves to the second first conveyor belt, the control assembly stops the second first conveyor belt. As the prefabricated blocks continue to move, the multiple first conveyor belts stop in sequence. At this point, the multiple prefabricated blocks are evenly arranged on the stopped first conveyor belts. When the last first conveyor belt near the head end of the loading chute stops, the second drive assembly drives the push rod to move, which pushes the prefabricated block on the first conveyor belt onto the lifting bracket. The operator then activates the winch to control the lowering of the lifting bracket to place the prefabricated block in the predetermined position. By providing the control assembly and the push rod, the control assembly controls the start and stop of the first conveyor belt, so that the multiple prefabricated blocks are evenly arranged and aligned with the installation position, eliminating the need for the operator to move the blocks multiple times, thereby improving installation efficiency and reducing labor intensity.

The prefabricated block pushes the first baffle to move along the length direction of the driving rod. The movement of the first baffle causes the corresponding first spur gear to move, and the first spur gear moves and moves away from the first crown gear. After the first spur gear moves away from the first crown gear, the first crown gear stops rotating and the corresponding first conveyor belt also stops running. At the same time, the third driving assembly drives the second baffle adjacent to the first baffle to move;

The second baffle moves under the action of the prefabricated block, and the movement of the second baffle causes the corresponding first spur gear to move, and the first spur gear moves and moves away from the first crown gear. After the first spur gear moves away from the first crown gear, the first crown gear stops rotating and its corresponding first conveyor belt also stops running, and then the third drive assembly drives the second baffle adjacent to the second baffle to move again, and so on.

[0055] Reference Figure 2 、 Figure 3 as well as Figure 4The first motor 14 rotates the drive rod 31. The rotation of the drive rod 31 rotates the first spur gear 32. The rotation of the first spur gear 32 rotates the corresponding first crown gear 33. The rotation of the first crown gear 33 rotates the drive roller 12. The rotation of the drive roller 12 causes the corresponding first conveyor belt 11 to operate. After the first prefabricated block enters the first conveyor belt 11, the first prefabricated block first abuts against the first baffle 41. The abutment of the prefabricated block with the first baffle 41 causes the first baffle 41 to move. The movement of the first baffle 41 causes the first spur gear 32 and the first rack 34 on the first baffle 41 to move. The first spur gear 32 on the first baffle 41 moves away from its corresponding first crown gear 33, and the first conveyor belt 11 at the bottom of the first baffle 41 stops.

[0056] The movement of the first rack 34 causes the second spur gear 35 on the adjacent mounting seat 43 to rotate, and the rotation of the second spur gear 35 causes the transmission shaft 36 to rotate. The rotation of the transmission shaft 36 causes the third spur gear 37 to rotate. The rotation of the third spur gear 37 causes the second rack 44 to move. The second rack 44 first causes the second baffle 42 close to the first baffle 41 to move. After the second prefabricated block enters the first conveyor belt 11, it abuts against the moved second baffle 42. The second prefabricated block pushes the second baffle 42 to move. The movement of the second baffle 42 causes the first spur gear 32 and the third rack 45 on the second baffle 42 to move. After the first spur gear 32 on the second baffle 42 moves, it moves away from its corresponding first crown gear 33, and the first conveyor belt 11 at the bottom of the second baffle 42 stops running.

[0057] After the third rack 45 moves, the second spur gear 35 on the adjacent mounting seat 43 rotates. Through the transmission shaft 36, the third spur gear 37 and the second rack 44, the second baffle 42 on the adjacent mounting seat 43 descends, and the third prefabricated block abuts against the descending second baffle 42, and so on.

The push rod 13 is arranged horizontally, and the extended end of the push rod 13 corresponds to the first conveyor belt 11. A second drive assembly is provided on the support frame 1, and the second drive assembly includes a first screw rod 46 and a second crown gear 47. The first screw rod 46 is horizontally passed through the top of the support frame 1, and the first screw rod 46 is rotatably connected to the support frame 1. The second crown gear 47 is fixedly sleeved on the end of the first screw rod 46 close to the first conveyor belt 11. The end of the first screw rod 46 away from the second crown gear 47 passes through the push rod 13, and the first screw rod 46 is threadedly engaged with the push rod 13. The first spur gear 32 on the third mounting seat 43 away from the first motor 14 can be meshed with the second crown gear 47. A plurality of support springs 131 are provided on the side wall of the push rod 13 away from the first conveyor belt 11, and the ends of the plurality of support springs 131 away from the push rod 13 are fixedly connected to the support frame 1.

A return spring 15 is fixedly connected to one side of the fourth spur gear 38, and the end of the return spring 15 away from the fourth spur gear 38 abuts the support frame 1.

[0060] Reference Figure 2 as well as Figure 4 When the first motor 14 causes the driving rod 31 to rotate, the fourth spur gear 38 rotates at the same time. The rotation of the fourth spur gear 38 causes the second crown gear 47 to rotate. The rotation of the second crown gear 47 causes the first screw rod 46 to rotate. The rotation of the first screw rod 46 causes the push rod 13 to move away from the first conveyor belt 11. Under the action of the support spring 131, the push rod 13 always maintains contact with the first screw rod 46.

[0061] Reference Figure 4 The fourth spur gear 38 is rotatably connected to the side wall away from the return spring 15, and the sleeve is slidably sleeved on the drive rod 31. The end of the sleeve away from the fourth spur gear 38 is rotatably connected to the third mounting seat 43 away from the first motor 14.

[0062] Reference Figure 2 as well as Figure 4 , when the prefabricated block moves to the last first conveyor belt 11 and abuts against its corresponding second baffle 42, the second baffle 42 causes the mounting seat 43 and the corresponding first spur gear 32 to move, and the movement of the first spur gear 32 causes the sleeve to move, and the movement of the sleeve causes the fourth spur gear 38 to move, and the fourth spur gear 38 moves and moves away from the second crown gear 47. The first spur gear 32 disengages from its corresponding first crown gear 33 and engages with the second crown gear 47. At this time, the first conveyor belt 11 stops, and the driving rod 31 continues to rotate and drives the first spur gear 32 to continue rotating. Although the first spur gear 32 and the fourth spur gear 38 have the same rotation direction, the first spur gear 32 and the fourth spur gear 38 are located on both sides of the second crown gear 47. The rotation of the first spur gear 32 will cause the second crown gear 47 to rotate in the opposite direction. The reversal of the second crown gear 47 causes the first screw rod 46 to reverse, and the reversal of the first screw rod 46 causes the push rod 13 to move toward the first conveyor belt 11.

[0063] Reference Figure 2 as well as Figure 4When the push rod 13 pushes the prefabricated block into the lifting bracket, the first baffle 41 and the second baffle 42 lose the push of the prefabricated block, and the first baffle 41 and the second baffle return to their initial positions under the action of the return spring 15. The first spur gear 32 re-engages with its corresponding first crown gear 33, and at the same time, the fourth spur gear 38 re-engages with the second crown gear 47. The push rod 13 moves away from the first conveyor belt 11 and returns to its initial position.

[0064] The implementation principle of a prefabricated block lifting equipment in an embodiment of the present application is: the first driving component 3 causes the driving roller 12 to rotate, and the rotation of the driving roller 12 causes the first conveyor belt 11 to run. The operator places the prefabricated block on the first conveyor belt 11, and the prefabricated block moves with the first conveyor belt 11. When the prefabricated block moves to the end of the loading chute, the control component 4 stops the first conveyor belt 11 at the end of the loading chute, and the second prefabricated block moves to the second first conveyor belt 11. The control component 4 stops the second first conveyor belt 11. As the multiple prefabricated blocks continue to move, the multiple first conveyor belts 11 stop in turn. At this time, the multiple prefabricated blocks are evenly arranged on the stopped first conveyor belt 11. When the last first conveyor belt 11 near the head end of the loading trough stops, the second drive component drives the push rod 13 to move. The push rod 13 moves to push the prefabricated blocks on the first conveyor belt 11 onto the lifting bracket. Then the operator starts the winch 2 to control the lifting bracket to descend and place the prefabricated blocks in the predetermined position. By setting the control component 4 and the push rod 13, the start and stop of the first conveyor belt 11 are controlled by the control component 4, and the multiple prefabricated blocks are evenly arranged and correspond to the installation position. The operator does not need to move them multiple times, which improves the installation efficiency and reduces the labor intensity.

[0065] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
