A lifting device for transporting and laying U-shaped steel

Abstract

This utility model proposes a lifting device for transferring and placing U-shaped reinforcing bars, belonging to the field of construction technology. The lifting device comprises a drive shaft, a telescopic motor, fixed clamps, and movable clamps. The movable clamps move back and forth to clamp the U-shaped reinforcing bars. When the bottom ends of the fixed and movable clamps are in contact on adjacent sides, a stable clamping mechanism is formed, ensuring that the U-shaped reinforcing bars will not fall after lifting, thus guaranteeing operational safety. The fixed and movable clamps are arranged in a corresponding array, allowing multiple U-shaped reinforcing bars to be clamped simultaneously, improving transfer efficiency. Furthermore, a matching U-shaped reinforcing bar placement support can be added later, reducing manual adjustment steps and improving work efficiency. In addition, the detachable first and second frames, and the adjustable number of second frames, allow for flexible adjustment of the lifting device width according to the size of the U-shaped reinforcing bars, adapting to different construction requirements and improving equipment versatility.

Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to a lifting device for transferring and laying U-shaped reinforcing bars. Background Technology

[0002] In construction, U-shaped reinforcing bars are a commonly used building material, and their transportation and placement are crucial steps in the construction process. Currently, traditional methods of transporting U-shaped reinforcing bars have several drawbacks. Firstly, using chains or wire ropes to bind the bars for hoisting requires frequent binding and unbinding operations, consuming significant manpower and time, resulting in low efficiency. Furthermore, relying solely on flexible binding tools during hoisting makes it difficult to ensure the stability of the U-shaped bars, easily leading to significant deformation and affecting project quality. Secondly, some existing hoisting equipment cannot flexibly adjust to the different specifications and sizes of the U-shaped bars, making them prone to displacement or even detachment during transport, posing significant safety hazards. In addition, when placing the U-shaped bars to their designated locations, manual sorting and positioning are often required again, further reducing construction efficiency. Therefore, developing a specialized hoisting tool that can improve the efficiency of U-shaped reinforcing bar transportation and placement while ensuring hoisting quality and safety is of significant practical importance.

[0011] This utility model discloses a lifting device for transporting and placing U-shaped ribs. It comprises a drive shaft, a telescopic motor, a fixed clamping plate, and a movable clamping plate. The movable clamping plate moves back and forth to clamp the U-shaped ribs.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, such as Figures 1-4 As shown, a lifting device for transporting and laying U-shaped ribs according to this application includes U-shaped ribs 9 and a first frame 1. The front outline of the first frame 1 is rectangular. At least one second frame 2 is symmetrically arranged at the left and right ends of the first frame 1. The second frame 2 and the first frame 1 are detachably installed. The end of the second frame 2 that is away from itself and connected to the first frame 1 is arranged in an array and fixedly connected to a fixing plate 3. The front of the fixing plate 3 is provided with a front and rear through mounting hole. A drive shaft 4 is slidably connected through the mounting hole.

[0023] In this application, a second frame 2 is provided at each of the left and right ends of the first frame 1; in addition, the number of second frames 2 can be increased or decreased according to the size of the U-shaped rib 9.

[0024] The second frame 2 has an L-shaped bracket 5 fixedly connected to the front of its end away from the first frame 1. A telescopic motor 6 is fixedly connected to the back of the vertical section of the bracket 5. The output end of the telescopic motor 6 is horizontally rearward. The output end of the telescopic motor 6 is fixedly connected to the drive shaft 4. Movable clamping plates 7 are also fixedly connected to and arranged in an array on the side of the drive shaft 4. Fixed clamping plates 3 and movable clamping plates 7 are arranged in pairs. The bottom of the side of the fixed clamping plates 3 and movable clamping plates 7 that are close to each other is accessible. Each pair of fixed clamping plates 3 and movable clamping plates 7 has a contact head 8 fixedly connected to the side of the side of the fixed clamping plates 3 and movable clamping plates 7 that are close to each other. The contact head 8 is accessible to a U-shaped rib 9. The fixed clamping plates 3 and movable clamping plates 7 can clamp the U-shaped rib 9. In this application, fourteen fixed clamping plates 3 and fourteen movable clamping plates 7 are arranged on each second frame 2. The telescopic motor 6 is started to control the movable clamping plates 7 to move back and forth.

[0025] During use, the U-shaped ribs 9 are vertically arranged. In this application, fourteen U-shaped ribs 9 are arranged at equal intervals. When the movable clamping plate 7 moves to the last point, it is at its farthest from the fixed clamping plate 3. Then, the first frame 1 is moved directly above the U-shaped ribs 9. The first frame 1 is lowered, and the fixed clamping plate 3 and the movable clamping plate 7 are respectively placed at the front and rear ends of the U-shaped ribs 9. The first frame 1 is lowered again until the contact head 8 contacts the U-shaped ribs 9. Then, the output end of the telescopic motor 6 is retracted, so that the movable clamping plate 3 moves to the foremost point. At this time, the bottom end of the side of the movable clamping plate 7 near the fixed clamping plate 3 contacts the bottom end of the side of the fixed clamping plate 3 near the movable clamping plate 7, thus clamping the U-shaped ribs 9. Then, the first frame 1 is moved to realize the transfer of the U-shaped ribs 9, ensuring that the U-shaped ribs 9 will not fall after being lifted.

[0026] The first frame 1 has a rectangular front cross section, and reinforcing profiles are integrally formed at a cross intersection between the top surfaces of the first frame 1; the second frame 2 has a triangular front cross section, and reinforcing profiles are integrally formed at a cross intersection between the top surfaces.

[0027] The first frame 1 and the second frame 2 are made of aluminum alloy;

[0028] Mounting plates 10 are fixedly connected to the four corners of the top surface of the first frame 1, and lifting rings 11 are fixedly connected to the top surface of the mounting plates 10; lifting rings 11 can be equipped with lifting hooks and other lifting tools.
