Description

Technical Field

[0001] This utility model relates to the field of plate lifting tools, specifically to a multi-functional plate component lifting tool. Background Technology

[0002] Precast slabs are commonly used prefabricated components in prefabricated buildings. Their hoisting process requires strict adherence to process requirements to ensure construction safety and component installation accuracy. Currently, most hoisting equipment used for precast slabs in building construction is rope-based. The process involves securing the four corners of the precast slab with four slings, and then fixing one end of each sling to a tower crane hook to complete the hoisting. Chinese utility model patent application number CN202222483355.3 discloses a frame-type lifting device for precast composite slab hoisting, including a frame, lifting lugs, fixed pulleys, and wire ropes. The frame includes two main beams and four distribution beams. The two main beams are arranged in parallel, with their ends aligned. The four distribution beams are positioned between the two main beams. The lifting lugs are located on the upper surfaces of the two main beams. The four fixed pulleys are located on the lower surfaces of the two main beams, with two fixed pulleys on each main beam. The fixed pulleys rotate in the vertical plane containing the main beams. One end of the wire rope is attached to one of the fixed pulleys, and the length of the wire rope inside the pulley is freely adjustable. The other end is configured to connect to a pre-reserved lifting point on the precast composite slab. The device can distribute force evenly through the four lifting points, ensuring stable hoisting of the component. However, the wire rope requires locking devices to be used for tightening during the extension and retraction process, making the structure relatively complex. Furthermore, the locking devices need to withstand downward tension, requiring high-quality components. Utility Model Content

[0003] The purpose of this utility model is to provide a multi-functional plate component lifting device to solve the above-mentioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This utility model discloses a multifunctional plate component lifting device, including a first steel cable, a second steel cable, a third steel cable, a left main beam, and a right main beam. The left and right main beams are connected by at least two crossbeams. The left and right main beams and the crossbeams form a rectangular frame structure. The top of the left and right main beams are provided with lifting lugs, and the bottom ends are provided with anchor holes. Three mounting brackets are spaced apart at the middle of the bottom. Each mounting bracket is provided with a pulley. The second steel cable passes through the pulley located in the middle and its two ends are respectively connected to a connecting ring. One end of the first steel cable is connected to the anchor hole, and the other end passes through the pulley near the anchor hole and is connected to the connecting ring near the anchor hole. One end of the third steel cable is connected to the connecting ring, and the other end is connected to the plate component.

[0006] As a preferred technical solution, the distance between the anchor hole and the mounting bracket is equal to the distance between the two mounting brackets.

[0007] As a preferred technical solution, the connecting ring is located below the middle between the two mounting brackets.

[0008] As a preferred technical solution, the connecting rings are located at the same horizontal level.

[0009] As a preferred technical solution, the beams are arranged at intervals.

[0010] As a preferred technical solution, the number of crossbeams is four.

[0011] As a preferred technical solution, two lifting lugs are respectively provided on the top of the left main beam and the right main beam, and the two lifting lugs are symmetrically arranged along the middle of the left main beam and the right main beam.

[0012] As a preferred technical solution, the mounting brackets located on both sides of the left and right main beams are slidably disposed at the bottom of the left and right main beams via a slider rail assembly.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] This utility model connects a third steel cable to a connecting ring, and then connects a first steel cable and a second steel cable to the connecting ring. The other end of the first steel cable is fixed to an anchor hole, and the two ends of the second steel cable are connected to the connecting ring after passing over a pulley. This allows the steel cables to stably lift the composite plate without the need for an additional locking mechanism. The structure is relatively simple, practical, and low in cost, and it has good stability during hoisting. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] Example 1

[0021] like Figure 1-3 As shown, this embodiment discloses a multi-functional plate component lifting device, including a first steel cable 1, a second steel cable 2, a third steel cable 3, a left main beam 4, and a right main beam 5. The left main beam 4 and the right main beam 5 are connected by at least two crossbeams 6. The left main beam 4, the right main beam 5, and the crossbeams 6 form a rectangular frame structure. Lifting lugs 7 are provided at the top of the left main beam 4 and the right main beam 5. The hook of the crane is connected to the lifting lugs 7 by a steel wire rope to lift this multi-functional plate component lifting device. Anchor holes 8 are provided at both ends of the bottom, and three mounting brackets 9 are provided at intervals in the middle of the bottom. Each of the mounting brackets 9... Each frame 9 is equipped with a pulley 10. The second steel cable 2 passes through the pulley 10 located in the middle and its two ends are respectively connected to a connecting ring 11. One end of the first steel cable 1 is connected to the anchor hole 8, and the other end passes through the pulley 10 near the anchor hole 8 and is connected to the connecting ring 11 near the anchor hole 8. One end of the third steel cable 3 is connected to the connecting ring 11, and the other end is connected to the plate component. The end of the third steel cable 3 connected to the plate component is equipped with a hook, and the hook is connected to the reserved lifting point on the plate component.

[0022] In use, this utility model uses four third steel cables 3 connected to the four corners of the steel plate, with a reasonable distribution of lifting points. During the lifting process, the steel plate is not easy to shake or tilt. The connection points between the lower part of the third steel cable 3 and the steel plate can be adjusted at will. The third steel cable 3 does not need to be in a straight downward position. The lower part of the third steel cable 3 can be opened outward to lift larger steel plates, or it can be retracted inward to lift smaller steel plates. It can flexibly adapt to steel plates of different sizes and shapes, expanding the applicable range of lifting. Furthermore, the force on the lifting device is distributed by the first steel cable 1 and the second steel cable 2 above the third steel cable 3, making the force on the lifting device more even. Compared with the prior art, the steel cable does not need to be equipped with an additional locking mechanism, which can also ensure the stability of the steel cable.

[0023] Example 2

[0024] like Figure 1-3As shown, this embodiment is based on Embodiment 1. Specifically, the distance between the anchor hole 8 and the mounting bracket 9 is equal to the distance between the two mounting brackets 9. This arrangement makes the lifting device more evenly stressed and the lifting more stable.

[0025] Furthermore, the connecting ring 11 is located below the center between the two mounting brackets 9. This arrangement ensures that the forces on both sides of the portion where the first steel cable 1 and the second steel cable 2 connect to the connecting ring 11 after passing through the pulley 10 are evenly distributed, further improving the stability of the hoisting.

[0026] Furthermore, the connecting rings 11 are located at the same horizontal level. This arrangement avoids situations where the lengths of the third steel cables 3 on both sides are different, and its purpose is also to ensure the stability of the hoisting.

[0027] Example 3

[0028] like Figure 1-3 As shown, this embodiment is based on Embodiment 1. Specifically, several of the crossbeams 6 are arranged at intervals to ensure the stress stability of the left main beam 4 and the right main beam 5. Preferably, in this embodiment, the number of crossbeams 6 is four.

[0029] Example 4

[0030] like Figure 1-3 As shown, this embodiment is based on Embodiment 1. Specifically, two lifting lugs 7 are respectively provided on the top of the left main beam 4 and the right main beam 5, and the two lifting lugs 7 are symmetrically arranged along the middle of the left main beam 4 and the right main beam 5. This arrangement is so that when the crane lifts this utility model, the crane hook can connect the four lifting lugs 7 through four steel wire ropes, ensuring the stability of this utility model when it is lifted by the crane.

[0031] Example 5

[0032] like Figure 1-3 As shown, this embodiment is based on Embodiment 1. Specifically, the mounting brackets 9 located on both sides of the left main beam 4 and the right main beam 5 are slidably disposed at the bottom of the left main beam 4 and the right main beam 5 via the slider rail assembly 12. The rail of the slider rail assembly 12 is arranged along the length direction of the left main beam 4 and the right main beam 5. The mounting brackets 9 on both sides are disposed on the slider of the slider rail assembly 12. The position of the mounting brackets 9 on both sides can be adjusted by the slider rail assembly 12, thereby changing the position of the connecting ring 11. The position of the third steel cable 3 moves accordingly to adapt to the lifting point position of the composite plate of different sizes. It should be noted that the slider rail assembly 12 is provided with a slider tightening device to tighten the slider. Since the slider tightening device is already very mature in the prior art, the structure of the slider tightening device will not be described in detail in this application.

[0033] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
