Description

Technical Field

[0001] This utility model relates to the field of electrical equipment hoisting technology, and specifically discloses a shockproof hoisting tool for electrical equipment. Background Technology

[0002] Currently, large electrical equipment is generally placed using a hoisting method. Protruding hooks are installed on both sides of the equipment near the ends. Four sets of slings are then connected to the hooks on a crane, and these slings are hung on the four protruding hooks. The crane then lifts the equipment. However, currently, during hoisting, the equipment falls directly to the ground, causing a significant impact on the cabinet and resulting in violent vibrations of the components inside.

[0003] Chinese patent CN218201756U discloses a shock-absorbing hoisting tool for electrical equipment, comprising: a hook mounted on a crane; four sets of identical fabric strips, each set having an upper connecting ring attached to the hook at one end and a lower connecting ring at the other end; each lower connecting ring having an installation structure, and each installation structure having a shock-absorbing structure; when the electrical equipment is about to be placed on the ground, the mounting rod is rotated so that it can be placed on the ground, thereby placing the support plate on the shock-absorbing structure at the bottom of the electrical equipment. When the electrical equipment is placed on the support plate, the damper and shock-absorbing spring can absorb the impact force when the electrical equipment is placed, greatly reducing the impact on the electrical equipment cabinet and preventing severe vibration of the components inside the electrical equipment cabinet.

[0004] The aforementioned document discloses a shock-absorbing hoisting tool for electrical equipment that can provide cushioning during the placement of electrical equipment. However, its shock-absorbing structure needs to be rotated to the bottom of the electrical equipment for use. After the electrical equipment is placed on the ground, it is necessary to support the electrical equipment in order to remove the lower connecting ring and the shock-absorbing structure, which is inconvenient to use. Therefore, a shock-absorbing hoisting tool for electrical equipment is needed to solve this problem. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0024] Please see Figure 1-4 An anti-vibration hoisting tool for electrical equipment includes a hanger 1, a first lifting ring 2 fixedly connected to the outer wall of the hanger 1, two support rods 3 provided on the lower side of the hanger 1, two second lifting rings 6 provided on the outer wall of each of the two support rods 3 through an adjustment mechanism, and two symmetrically distributed buffer mechanisms provided on the outer wall of each of the two support rods 3.

[0025] The buffer mechanism includes a sleeve 10 that passes through and is threaded to the inner wall of the support rod 3. A slide rod 11 is slidably connected inside the sleeve 10. A support block 12 is fixedly connected to the lower end face of the slide rod 11. A limit ring 13 is fixedly connected to the lower end of the outer wall of the sleeve 10. A spring 14 is sleeved on the outer wall of the slide rod 11 between the support block 12 and the limit ring 13.

[0026] In this embodiment, hooks for hanging the second lifting rings 6 are provided at the bottom of both sides of the electrical equipment near the ends. The four second lifting rings 6 are hung on the four hooks respectively, and the first lifting ring 2 is hung on the hook of the lifting equipment. The electrical equipment is then lifted by the lifting equipment and moved to the designated position. When the electrical equipment lands, the sliding rod 11 slides upward relative to the sleeve 10, thereby compressing the spring 14. The spring 14 buffers the impact force when the electrical equipment lands, greatly reducing the impact on the electrical equipment. After the electrical equipment lands, the sleeve 10 is rotated by the wrench, and the sleeve 10 moves upward. This causes the sliding rod 11 to move upward through the limiting plate 15, so that the support block 12 is lifted off the ground. This allows the second lifting rings 6 to be removed from the hooks on the outer wall of the electrical equipment, making it easy to remove.

[0027] As a technical optimization of this utility model, the adjustment mechanism includes a slide groove 4 that runs through the outer wall of the support rod 3, a threaded rod 8 that is rotatably connected inside the slide groove 4, and sliders 5 that are threaded to both ends of the outer wall of the threaded rod 8, and a second lifting ring 6 that is fixedly connected to the lower end face of the slider 5.

[0028] In this embodiment: rotating the threaded rod 8 causes the two sliders 5 to move synchronously relative to each other or in opposite directions along the slide groove 4, thereby adjusting the distance between the two second lifting rings 6 on the same side, which facilitates the lifting of electrical equipment of different specifications and is highly practical.

[0029] As a technical optimization of this utility model, the adjustment mechanism also includes a limiting rod 9 fixedly connected inside the slide groove 4, and the slider 5 is slidably connected to the limiting rod 9.

[0030] In this embodiment, the limiting rod 9 facilitates the limiting of the slider 5, making the movement of the slider 5 stable.

[0031] As a technical optimization of this utility model, the thread directions at both ends of the outer wall of the threaded rod 8 are opposite.

[0032] In this embodiment, by setting the thread directions at both ends of the outer wall of the threaded rod 8 to be opposite, it is convenient that when the threaded rod 8 is rotated, the two second lifting rings 6 can be driven to move synchronously relative to each other or in opposite directions.

[0033] As a technical optimization of this utility model, two suspension ropes 7 are fixedly connected to both ends of the outer wall of the hanger 1, and the other ends of the four suspension ropes 7 are fixedly connected to four sliders 5 respectively.

[0034] In this embodiment, the slider 5 and the support rod 3 can be easily lifted by the suspension rope 7.

[0035] As a technical optimization of this utility model, a limiting plate 15 is fixedly connected to the upper end face of the slide rod 11.

[0036] In this embodiment, a limiting plate 15 is fixedly connected to the upper end face of the slide rod 11 to prevent the slide rod 11 from coming off the sleeve 10.

[0037] As a technical optimization of this utility model, a nut 16 is fixedly connected to the outer wall of the sleeve 10.

[0038] In this embodiment, by fixing the nut 16 to the outer wall of the sleeve 10, it is easy to rotate the sleeve 10 with a wrench, saving time and effort.

[0039] The working principle and usage process of this utility model are as follows: First, the first lifting ring 2 is suspended on the hook of the lifting equipment. Then, the four second lifting rings 6 are respectively hung on the four hooks on the outer wall of the electrical equipment. The lifting equipment then lifts the electrical equipment and moves it to the designated position. When the electrical equipment lands, the sliding rod 11 slides upward relative to the sleeve 10, compressing the spring 14. The spring 14 buffers the impact force when the electrical equipment lands, greatly reducing the impact on the electrical equipment. After the electrical equipment lands, the sleeve 10 is rotated by a wrench, causing it to move upward. This, in turn, drives the sliding rod 11 upward through the limiting plate 15, causing the support block 12 to detach from the ground. This allows the second lifting rings 6 to be easily removed from the hooks on the outer wall of the electrical equipment. Rotating the threaded rod 8 drives the two sliders 5 to move synchronously relative to or away from each other along the sliding groove 4, thereby adjusting the distance between the two second lifting rings 6 on the same side. This facilitates the lifting of electrical equipment of different specifications and is highly practical.
