Description

Technical Field

[0001] The utility model relates to the technical field of motor hoisting, and more particularly to a motor hoisting auxiliary device. Background Art

[0002] During workshop maintenance, electromechanical equipment often needs to be inspected and adjusted. For the disassembly and assembly of motors, the traditional method is mainly to concentrate manpower to lift the electrodes. This requires multiple workers to coordinate the construction, which is not only labor-intensive and inefficient, but also poses safety hazards. Based on this, many maintenance personnel cleverly use hydraulic trolleys or overhead cranes to lift motors. For example, the auxiliary lifting device for electromechanical engineering installation disclosed in the publication number CN218453919U not only improves work efficiency but also improves safety. However, the hydraulic trolley lifting method requires a larger space to accommodate the hydraulic trolley, and its use has limitations. The overhead crane lifting method is relatively simpler and can be achieved by hooking the motor with a hook. However, whether it is a hydraulic trolley or an overhead crane lifting method, after the motor is lifted, the motor is in a suspended state. During the lifting or lowering process, it is easy to collide with other machinery and equipment, which can easily cause damage to the motor.

[0003] Therefore, it is urgent to design a new type of motor lifting auxiliary device to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a motor lifting auxiliary device in view of the above-mentioned deficiencies in the prior art, which can effectively protect the motor during the motor lifting process and avoid the problem of motor damage.

[0005] The technical solution of the utility model is as follows: a motor lifting auxiliary device includes a boom and a hook, the hook is fixed at the bottom of the boom, a lifting ring is fixed on the top of the boom, a protective cage is slidingly sleeved on the boom, the protective cage is a rectangular frame, and the length and width of the protective cage are greater than the length and width of the motor, a limiting block is fixed on the boom above the hook, and an adsorption block for adsorbing and fixing the protective cage is fixed on the boom below the lifting ring, and the distance between the limiting block and the adsorption block is greater than the height of the protective cage.

[0006] As a further improvement, the protective cage includes a sliding sleeve, a top plate and several surrounding rods. The sliding sleeve is slidably mounted on the suspension rod, and the top plate is fixedly mounted on the periphery of the sliding sleeve. Several of the surrounding rods are evenly fixed at the bottom of the outer edge of the top plate, and each of the surrounding rods is perpendicular to the top plate.

[0007] Furthermore, the sliding sleeve is made of iron material, and the adsorption block is a magnet block.

[0008] Furthermore, a rubber pad is provided on the top surface of the limit block.

[0009] Furthermore, the suspension rod comprises two vertical rods with the same diameter, and the two vertical rods are detachably connected.

[0010] Furthermore, a threaded rod is provided at the bottom of one section of the vertical rod, and a threaded groove is provided at the top of the other section of the vertical rod, and the threaded rod is threadedly connected in the threaded groove.

[0011] Beneficial effects

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. The motor lifting auxiliary device of the present invention is provided with a sliding protective cage on the boom. When in use, the protective cage is first slid upward, and the protective cage is fixed by the adsorption block to expose the hook. Then the hook can be hooked on the motor, and the protective cage is pulled downward to cover the motor. The hook of the overhead crane is then hooked on the lifting ring, and the motor can be lifted by the overhead crane. The protective cage can effectively protect the motor during the motor lifting process to prevent the motor from being damaged by bumps.

[0014] 2. The motor lifting auxiliary device of the present invention has a lifting rod composed of two detachable vertical rods. During actual use, the two vertical rods can be separated, so that the protective cage can be removed and replaced with protective cages of different sizes. In this way, motors of different sizes can be lifted and protected, and the scope of application is wider. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The motor lifting auxiliary device of the present invention is characterized in that a slidable protective cage is provided on the lifting rod. When in use, the protective cage is first slid upward, and the protective cage is fixed by an adsorption block to expose the hook. Then the hook can be hooked onto the motor, and the protective cage is pulled downward to cover the motor. The hook of the overhead crane then hooks onto the lifting ring, and the overhead crane can be used to lift the motor.

The plurality of surrounding rods 43 are evenly fixed to the bottom of the outer edge of the top plate 42, and each surrounding rod 43 is perpendicular to the top plate 42, forming a rectangular frame with a hollow structure, ensuring that the protective cage 4 can be sleeved around the periphery of the motor. Furthermore, the sleeve 41 is made of iron material, and the adsorption block 6 is a magnet block, which uses magnetism to adsorb and fix the sleeve 41, thereby achieving a fixed position of the protective cage 4, satisfying that the protective cage 4 can be pulled downward while being more convenient to operate.

[0024] Preferably, a rubber pad is provided on the top surface of the limit block 5. When the protective cage 4 falls, it forms a flexible contact with the rubber pad to play a buffering role and avoid the problem of rigid collision.

Specifically, a threaded rod 12 is provided at the bottom of one vertical rod 11, and a threaded groove 13 is provided at the top of the other vertical rod 11, wherein the threaded rod 12 is threadedly connected to the threaded groove 13, thereby detachably connecting the two vertical rods 11.
