Description

Technical Field

[0001] This utility model relates to the technical field of motor disassembly and assembly auxiliary equipment, specifically to a motor handling tool. Background Technology

[0002] In the production process of polyester fiber, the normal operation of the motor is crucial, affecting the linear density deviation rate, a physical property of the fiber. Unstable motor operation or motor damage can severely impact production stability and product quality; therefore, damaged motors need to be replaced promptly. Currently, motor installation areas are not fixed; some are mounted on the ground, but many more are installed on supports at varying heights. Due to equipment limitations, at least four people are required to lift the motor during replacement, and this is all done manually. Because the working environment in polyester production workshops is often poor, and some operating spaces do not allow for multiple people to lift the motor simultaneously, workplace injuries frequently occur during motor assembly and disassembly. Furthermore, transportation also poses a health risk to workers. Therefore, to save manpower and improve the working environment, it is necessary to develop a motor handling tool that can be flexibly moved across the factory floor to solve these problems. Summary of the Invention

[0003] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide a motor handling tool that can save manpower, improve the working environment, and enhance operational safety.

[0004] To address the aforementioned technical problems, the objective of this application is achieved through the following technical solution: A motor handling tool includes a movable base with movable wheels, a support mechanism mounted on the movable base, a suspension arm with one end mounted on the support mechanism, a lifting mechanism mounted on the suspension arm, and a hook for lifting control via the lifting mechanism. One end of the suspension arm extends forward at an angle, and the hook is suspended from the front end of the suspension arm via the lifting mechanism. After the motor to be handled is fixed by the hook, it is lifted upward by the lifting mechanism and then moved by pushing the movable base.

[0005] Preferably, the lifting mechanism includes a hand chain hoist located at the rear end of the suspension arm, a lifting chain with one end fixed to the hook, and a hand chain for winding or releasing the lifting chain, with the hanging ends of the lifting chain and the hand chain located on the movable base.

[0006] Preferably, the upper end face and the top front end of the suspension arm are provided with a plurality of spaced limiting rings.

[0007] Preferably, a cylindrical transition shaft is provided at the top corner of the suspension arm.

[0008] Preferably, the suspension arm is made of 3-4m long H or C-shaped channel steel, the front end of the suspension arm is provided with a sealing plate, the limiting ring on the upper end face of the suspension arm is made of steel pipe with an inner diameter of 40-45mm, the limiting ring on the sealing plate has an arc-shaped structure, and the transition shaft is located at the top of the sealing plate. Preferably, the hook includes a horizontal arm, hanging rods at both ends of the horizontal arm, and a metal hook at the lower end of the hanging rods. A fixing hole is provided in the middle of the horizontal arm, and the lifting chain is fixed in the fixing hole by bolts.

[0009] Preferably, the support mechanism is composed of several channel steels and metal plates welded together, and the suspension arm is fixed at an angle through the support mechanism.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The motor handling tool can be moved on the factory ground via a mobile base. When it is necessary to move motors in different areas, the motor can be directly suspended on the hook and lifted by the lifting mechanism for movement. This makes the motor handling process safer, reduces labor intensity, and effectively improves the working environment. Attached Figure Description

It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, without limiting the number of objects; for example, a first object can be one or more.

[0015] like Figure 1 As shown, a motor handling tool includes a movable base 2 with movable wheels, a support mechanism 3 mounted on the movable base 2, a suspension arm 7 with one end mounted on the support mechanism 3, a lifting mechanism 9 mounted on the suspension arm 7, and a hook 4 for lifting control via the lifting mechanism 9. One end of the suspension arm 7 extends forward at an angle, and the hook 4 is suspended at the front end of the suspension arm 7 via the lifting mechanism 9. After the motor to be handled is fixed by the hook 4, it is lifted upward by the lifting mechanism 9 and then moved by pushing the movable base 2.

[0016] The mobile base 2 consists of four casters, one omnidirectional wheel, and a metal platform with a handle, ensuring both stability and flexibility during movement. One end of the suspension arm 7 is fixed to the mobile base 2 via the support mechanism 3. The hook 4 is suspended from the front end of the suspension arm 7 via the lifting mechanism 9. When the motor needs maintenance, it is removed from the equipment, creating an initial separation. Then, the two ends of the motor are secured with straps, wire ropes, or chains and hooked onto the hook 4. The lifting mechanism 9 then moves the hook 4 up and down, lifting the motor for movement. Because one end of the suspension arm 7 extends forward at an angle, it can adapt to different motor installation scenarios when lifting the motor. Even if the motor is not on the ground but mounted on a frame, it can still be lifted, expanding its application range. During motor handling, only one person needs to hold the motor to prevent violent shaking during suspension, resulting in higher safety and lower labor intensity. The working environment during handling is effectively improved, eliminating the need for manual operation around the motor.

[0017] A further improvement is made to the lifting mechanism 9, which includes a hand chain hoist 92 located at the rear end of the suspension arm 7, a lifting chain 91 with one end fixed to the hook 4, and a hand chain 93 for winding or releasing the lifting chain 91. The hanging ends of the lifting chain 91 and the hand chain 93 are located on the movable base 2.

[0018] The lifting mechanism 9 consists of a hand chain hoist 92, a lifting chain 91, and a hand chain 93. The main body of the hand chain hoist 92 is welded to the end of the suspension arm 7. One end of the lifting chain 91 extends upward along the suspension arm 7 and then hangs down from the top. The hook 4 is fixed to the front end of the lifting chain 91, while the rear end can be placed directly on the mobile base 2. The hand chain 93 is also placed directly on the mobile base 2. Since this structure can be purchased online, the cost is lower. Moreover, during operation, it does not require the use of electric components. The lifting chain 91 can be retracted by manually pulling the hand chain 93, which provides good stability. Compared with other structures, using the hand chain 93 to manually retract the lifting chain 91 is more in line with operational rationality when controlling the lifting height of the motor. It will not cause problems such as lifting too high or suddenly dropping, and it can also avoid the safety issues that exist when driving through other structures.

[0019] Further improvements, such as Figure 3As shown, the upper end face and the top front end of the suspension arm 7 are provided with several spaced limiting rings 8; a cylindrical transition shaft 6 is provided at the top corner of the suspension arm 7; the suspension arm 7 is made of 3-4m long H or C-shaped channel steel, the front end of the suspension arm 7 is provided with a sealing plate 5, the limiting rings 8 on the upper end face of the suspension arm 7 are made of steel pipes with an inner diameter of 40-45mm, the limiting rings 8 on the sealing plate 5 are arc-shaped structures, and the transition shaft 6 is located on the top of the sealing plate 5.

[0020] Because the lifting chain 91 needs to extend forward when acting on the hook 4, multiple limiting rings 8 are installed at intervals at the top of the approximately 4m long suspension arm 7 to ensure the chain's position. The lifting chain 91 extends forward after passing through each limiting ring 8, resulting in better stability during operation. In particular, a sealing plate 5 is welded to the top of the suspension arm 7, with an arc-shaped limiting ring 8 and a cylindrical transition shaft 6 welded to it. As the lifting chain 91 descends from the upper end of the suspension arm 7, it can make an arc transition through the transition shaft and be limited by the arc-shaped limiting ring 8, ensuring a smoother transition and more stable position for the descending lifting chain 91, preventing corner jamming. The suspension arm 7 is made of H or C-shaped channel steel, providing better strength and resistance to bending. The limiting rings 8 are made of steel pipe with an inner diameter of 40-45mm, effectively ensuring smooth passage of the lifting chain 91 and allowing it to slide during winding or release.

[0021] Further improvements include, for example Figure 2 As shown, the hook 4 includes a horizontal arm 43, hanging rods 42 at both ends of the horizontal arm 43, and a metal hook 41 at the lower end of the hanging rods 42. A fixing hole 46 is provided in the middle of the horizontal arm 43, and the lifting chain 91 is fixed in the fixing hole 46 by bolts 45.

[0022] The middle of the crossbar is fixed to the end of the lifting chain 91 by bolts 45. Hanging rods 42 and metal hooks 41 are symmetrically welded at both ends of the crossbar. The hanging rods 42 are made of steel bars with a diameter of 12mm or more, and the metal hooks 41 are made of steel bars with a diameter of 6mm or more bent to ensure firmness and easy material availability. In order to prevent the crossbar 43 from falling off when connected to the lifting chain 91 by bolts 45, the structure of the crossbar 43 is improved. A downward recessed groove 44 is formed in the middle of the crossbar 43, so that the top link of the lifting chain 91 can be inserted into the groove 44 and then fixed by bolts 45 through the fixing holes 46 on both sides.

[0023] A further improvement is that the support mechanism 3 is composed of several channel steels and metal plates welded together, and the suspension arm 7 is fixed at an angle through the support mechanism 3. The structure is simpler, and the channel steels and metal plates are connected by welding, resulting in higher sturdiness after assembly and good stability during the support process, making it less likely to tip over or fall. In order to prevent the mobile base 2 from tipping over during the lifting process, a counterweight is generally provided on the mobile base 2. The counterweight can be a discarded mechanical part.

[0024] A further improvement is that the movable base 2 is also provided with a storage box 1, and the hand chain 93 hanging on the movable base 2 is stored through the storage box 1. The support mechanism 3 is also provided with an anti-detachment rod 10 on the rear side, and the hook of the hand chain hoist 92 hooks into the hole on the anti-detachment rod 10.

[0025] Because the chain 93 of the hand chain hoist 92 is relatively long, a large portion of it is scattered on the moving base 2, which could cause it to fall out during movement. Therefore, a storage box 1 is installed on the moving base 2 to store the excess chain 93, thus preventing it from causing problems during movement. Furthermore, since the hand chain hoist 92 is welded in place, and the motor at the front end of the lifting chain 91 is quite heavy, any problems at the weld could easily cause the motor and the hand chain hoist 92 to detach forward. To avoid this, a perforated anti-detachment rod 10 is welded to the rear side of the support mechanism 3. This allows the hook on the hand chain hoist 92 to hook into the hole of the anti-detachment hook. If the weld separates, the hook can provide secondary fixation, preventing accidents.

[0026] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
