Description

Technical Field

[0001] This utility model relates to the field of lifting tools, specifically to a lifting tool for repairing electrical equipment. Background Technology

[0002] Lifting tools are tools or devices used for lifting and moving goods. When lifting and maintaining electrical equipment, because some electrical equipment is quite large and heavy, it is usually necessary to use lifting tools to lift and move the electrical equipment before it can be easily maintained.

[0003] The existing lifting equipment still has the following problems when used: the existing lifting equipment can only lift individual electrical devices, which results in low efficiency of overall lifting, moving and maintenance. At the same time, some individual electrical devices are relatively light, so if the electrical devices are not handled carefully during the lifting and maintenance process, the lifting ropes may sway, affecting the maintenance work.

[0004] Therefore, it is necessary to invent a lifting tool for repairing electrical equipment to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a lifting tool for electrical equipment repair, in order to solve the problem mentioned in the background art that the existing lifting tools can only lift individual electrical equipment, which results in low efficiency of overall lifting and moving for maintenance. At the same time, some individual electrical equipment is relatively light, so if the electrical equipment is not handled carefully during the lifting and maintenance process, the lifting rope may sway, affecting the maintenance work.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lifting tool for repairing electrical equipment, comprising a lifting ring, a connecting rod fixedly connected to the inner wall of the lifting ring, and a lifting rope fixedly connected to the top of the connecting rod, an installation block movably mounted on the outside of the lifting ring, and a threaded rod threadedly connected to the inside of the installation block through a threaded groove, the threaded rod matching a pre-set threaded groove inside the lifting ring, a lever fixedly connected to the top of the threaded rod, and an annular block movably mounted inside the lever, the annular block and the installation block being movably connected through a spring body, and a hook fixedly connected to the bottom of the installation block.

[0007] Preferably, the connecting rod is in the shape of a cross, and each of the four small rods of the cross-shaped connecting rod is fixedly connected with a lifting rope. Furthermore, the four sets of inclined lifting ropes are fixedly connected to the vertical lifting rope to ensure the stability of the lifting ring when it is subsequently lifted.

[0008] Preferably, the mounting block has an open mounting port inside, and the inner wall of the mounting port is attached to the outer wall of the lifting ring to achieve a movable connection. The mounting port is connected to the threaded groove, which facilitates the threaded connection between the mounting block and the lifting ring.

[0009] Preferably, the threaded groove is provided in several places, and the several threaded grooves are distributed in a ring at equal angles on the lifting ring. The upper and lower ends of the threaded groove are both through, which facilitates the threaded connection between the mounting block and the threaded groove at different positions. This facilitates the subsequent lifting of multiple sets of equipment and makes it easy to allocate the position of the electrical equipment on the lifting ring according to the weight of the electrical equipment to be lifted.

[0010] Preferably, the annular block is composed of an annular block one and an annular block two fixedly connected to the annular block one, and the outer diameter of the annular block one is larger than the outer diameter of the annular block two. The annular block one and the annular block two are coaxially installed, and the central areas of the annular block one and the annular block two are provided with through holes.

[0011] The outer wall of the annular block is attached to the inner wall of the annular groove to achieve a sliding connection, so that the rotation of the threaded rod driven by the actuating block will not affect the spring body.

[0012] Preferably, the upper and lower ends of the spring body are fixedly connected to the top wall of the annular block and the mounting block, respectively.

[0013] Preferably, the inner diameter of the through hole is larger than the outer diameter of the threaded rod, so that the annular block will not affect the rotation of the threaded rod.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model uses a lever to drive the threaded rod to rotate. Once the threaded rod rotates and forms a threaded connection with the threaded groove, the mounting block and lifting ring can be installed. In this way, the electrical equipment to be hoisted can be lifted and moved by the hook, which facilitates the subsequent maintenance of heavier electrical equipment. At the same time, when the lever is turned, the annular block inside the lever is connected to the spring body, so the spring body will not affect the rotation of the lever. Meanwhile, the connection effect of the spring body ensures that the mounting block and the threaded rod will not fall off.

[0016] 2. The mounting block and the threaded grooves at different positions are threaded together to facilitate the subsequent hoisting of multiple sets of equipment. At the same time, it is convenient to distribute the position of the electrical equipment on the lifting ring according to the weight of the electrical equipment to be hoisted.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-4 The illustrated lifting tool for repairing electrical equipment includes a lifting ring 1. A connecting rod 2 is fixedly connected to the inner wall of the lifting ring 1, and a lifting rope 3 is fixedly connected to the top of the connecting rod 2. An installation block 4 is movably installed on the outside of the lifting ring 1, and a threaded rod 9 is threadedly connected to the inside of the installation block 4 through a threaded groove 8. The threaded rod 9 matches a pre-set threaded groove 7 inside the lifting ring 1. A lever 10 is fixedly connected to the top of the threaded rod 9, and an annular block is movably installed inside the lever 10. The annular block and the installation block 4 are movably connected through a spring body 14. A hook 6 is fixedly connected to the bottom of the installation block 4.

[0026] The connecting rod 2 is in the shape of a cross, and each of the four small rods of the cross-shaped connecting rod 2 is fixedly connected with a suspension rope 3. Furthermore, the four sets of inclined suspension ropes 3 are fixedly connected to the vertical suspension rope 3 to ensure the stability of the lifting ring 1 when it is subsequently lifted.

[0027] The mounting block 4 has an open mounting port 5 inside, and the inner wall of the mounting port 5 is attached to the outer wall of the lifting ring 1 to achieve a movable connection. The mounting port 5 is connected to the threaded groove 8, which facilitates the threaded connection between the mounting block 4 and the lifting ring 1.

[0028] The threaded groove 7 is provided in several places, and the threaded groove 7 is distributed in a ring at equal angles on the lifting ring 1. The upper and lower ends of the threaded groove 7 are both through, which makes it easy for the mounting block 4 to be threadedly connected to the threaded groove 7 at different positions. This facilitates the subsequent lifting of multiple sets of equipment and makes it easy to distribute the position of the electrical equipment on the lifting ring 1 according to the weight of the electrical equipment to be lifted.

[0029] The annular block is composed of an annular block 11 and an annular block 2 12 fixedly connected to the annular block 11. The outer diameter of the annular block 11 is larger than the outer diameter of the annular block 2 12. The annular block 11 and the annular block 2 12 are coaxially installed, and a through hole 15 is provided in the central area of ​​the annular block 11 and the annular block 2 12.

[0030] The outer wall of the annular block is attached to the inner wall of the annular groove 13 to achieve a sliding connection, so that when the dial block 10 drives the threaded rod 9 to rotate, it will not affect the spring body 14.

[0031] The upper and lower ends of the spring body 14 are fixedly connected to the annular block 12 and the top wall of the mounting block 4, respectively.

[0032] The inner diameter of the through hole 15 is larger than the outer diameter of the threaded rod 9, so that the annular block will not affect the rotation of the threaded rod 9.

[0033] Working principle: When using a lifting tool for electrical equipment repair, firstly, the rotation of the threaded rod 9, which is fixedly connected to the inner wall of the pre-set annular groove 13 inside the toggle block 10, is driven by the toggle block 10. The threaded rod 9 is threadedly connected to the threaded groove 7 and the threaded groove 8 inside the lifting ring 1. After the threaded rod 9 rotates and is threadedly connected to the threaded groove 7, the installation block 4 and the lifting ring 1 can be installed. This makes it convenient to lift and move the electrical equipment to be lifted through the hook 6 fixedly connected to the bottom of the installation block 4, which is convenient for subsequent maintenance of heavier electrical equipment. At the same time, when the toggle block 10 is turned to adjust the rotation of the threaded rod 9 fixedly connected to the toggle block 10, the annular block inside the toggle block 10 is connected to the spring body 14 fixedly connected to the top of the installation block 4. In this way, the spring body 14 will not affect the rotation of the toggle block 10, and the connection effect of the spring body 14 will prevent the installation block 4 and the threaded rod 9 from falling off.

[0034] Meanwhile, when installing multiple mounting blocks 4 to hoist multiple sets of electrical equipment, the electrical equipment can be distributed on the lifting ring 1 according to its weight, thus ensuring that the lifting ring 1 will not shift during the hoisting process and affect subsequent hoisting.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
