Description

Technical Field

[0001] This utility model belongs to the field of building engineering safety protection, and in particular relates to a fully enclosed sound barrier installation anti-fall device. Background Technology

[0002] Fully enclosed sound barriers are widely used in transportation facilities such as roads and railways to reduce noise pollution. However, the installation of sound barriers often involves working at heights and near edges, posing significant safety risks. The installation of sound barrier fall arrestors and supporting structures suffers from complex connections, low efficiency, and insufficient safety. Therefore, there is an urgent need for a fall arrestor that can improve construction efficiency while ensuring safety. Summary of the Invention

[0003] The problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a fully enclosed sound barrier installation anti-fall device.

[0004] This invention is achieved through the following technical solution:

[0005] A fully enclosed sound barrier installation anti-fall device includes four vacuum suction cups, which are respectively attached to the four corners of the sound barrier. The vacuum suction cups are fixed upwards with connecting ropes, and the connecting ropes are all fixed to the bottom end of steel wire ropes. The upper end of the steel wire ropes is fixed to the anti-fall device, and the connecting ring at the upper end of the anti-fall device is hung on a U-shaped hanging ring. The U-shaped hanging ring includes a U-shaped ring and a bolt passing through the U-shaped ring. The connecting ring is sleeved on the bolt, and nuts are provided at both ends of the bolt.

[0006] Preferably, the vacuum suction cup is a three-claw suction cup.

[0007] Preferably, the fall arrestor is a speed-differential fall arrestor.

[0008] The device of this invention can quickly connect the fall arrestor to the sound barrier support structure through a U-shaped hanging ring. The operation is quick and simple, and it can be quickly assembled and disassembled, which improves construction efficiency. The use of multiple vacuum suction cups to grip the sound barrier allows for multi-point force application, which increases safety. Attached Figure Description

[0013] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0014] This embodiment includes four vacuum suction cups 1, each a three-claw suction cup, capable of multi-point adsorption. The four suction cups 1 are respectively attached to the four corners of the sound barrier 2, with evenly distributed adsorption force. Connecting ropes 3 are fixed upwards to the vacuum suction cups 1. The upper ends of all four connecting ropes 3 are fixed to the bottom end of a steel wire rope 4. The upper end of the steel wire rope 4 is fixed to a fall arrester 5. The connecting ring 6 at the upper end of the fall arrester 5 is hung on a U-shaped hanging ring. The fall arrester 5 is preferably a speed-differential type, capable of responding to a fall and automatically locking within 0.2 seconds. It has a buffer length ≤20cm, a maximum dynamic load capacity of 100kN, and a buffer mechanism to avoid concentrated impact force and reduce damage to the material and device from the fall impact.

[0015] The aforementioned U-shaped hanging ring includes a U-shaped ring 7 and a bolt 8 that passes laterally through the U-shaped ring 7. The U-shaped ring 7 is used to hang on the support structure of the sound barrier 2, and the bolt 8 is used to lock the U-shaped ring 7 to the support structure. The connecting ring 6 at the upper end of the fall arrester 5 is fitted onto the bolt 8, and nuts 9 are provided at both ends of the bolt 8.

[0016] When installing the sound barrier 2, four vacuum suction cups 1 are used to attach to the four corners of the sound barrier 2. The U-shaped ring 7 is hung on the upper support structure of the sound barrier 2. The bolt 8 is passed through one side of the U-shaped ring 7. Then, the connecting ring 6 of the fall arrestor 5 is put on the bolt 8, and the bolt 8 is passed through the other side of the U-shaped ring 7. The nuts 9 on both sides of the bolt 8 are tightened to connect the U-shaped hanging ring to the support structure. Then, the worker stands on the aerial platform 10 and supports the lower surface of the sound barrier 2 with his hands. As the aerial platform 10 rises, the worker lifts the sound barrier 2 and gradually raises it for installation. In this process, the sound barrier 2 can be effectively prevented from falling midway. Moreover, the connection between the fall arrestor 5 and the support structure is simpler and faster than the existing method. The U-shaped hanging ring can be quickly connected and disassembled with the support structure, which improves construction efficiency.

[0017] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; those skilled in the art should understand that modifications can still be made to the technical solutions described in the above embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
