Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a wheel single hook lifting device. Background Technology

[0002] A single-hook wheel lifter is a device used to support wheels. In the manufacturing, repair, and assembly of railway locomotives and rolling stock (including freight cars, passenger cars, and EMUs), the handling and lifting of individual wheels is a fundamental and arduous task. Individual wheels are heavy (ranging from tens to hundreds of kilograms) and have a typical rotating structure, but their shape (such as the tread, flange, and spoke holes) makes stable gripping difficult. Before the widespread use of specialized lifting tools, workshops typically handled individual wheels in the following ways: Wire rope / chain hoisting: A wire rope or chain is passed through the inside of the wheel and hoisted around the wheel for lifting. This is the most primitive method.

[0003] Manual handling / simple tools: For small wheels, relying on manpower or using pry bars, handcarts, etc. is extremely inefficient and dangerous.

[0004] Electromagnetic crane: It uses an electromagnetic chuck to attach to the wheel tread for lifting. With the continuous development of technology, people's requirements for wheel single hook lifting tools are also getting higher and higher.

[0005] Existing wheel-mounted single-hook lifting devices have certain drawbacks in use, such as slippage and falling: The surface of the wheel (especially the tread) is a smooth curved surface, and the wire rope hoisting is extremely unstable. It is easy to slip during shaking, causing hundreds of kilograms of heavy objects to fall, posing a fatal threat to personnel and equipment below.

[0006] Personal injury: Manual handling can easily cause workplace injuries such as crushing and sprains.

[0007] Surface scratches: Wire ropes or chains come into direct contact with the precision-machined surfaces of wheels (especially the tread and flange), making them prone to scratches, indentations, or impacts in these critical areas. Any damage to the tread will affect the contact relationship between the wheel and the rail, causing noise, vibration, and even traffic safety accidents.

[0008] Magnetic effects: Although electromagnetic cranes avoid contact damage, strong magnetic fields may have a potential impact on the performance of wheel materials and pose a risk of falling in the event of a sudden power outage. Safety depends on backup power.

[0009] Wire rope hoisting requires repeated threading and hooking, making the operation cumbersome, time-consuming, and labor-intensive.

[0010] Manual handling is a bottleneck to efficiency and cannot keep up with the fast pace of modern production and maintenance.

[0011] When lifting wheels onto axles for press-fitting, traditional lifting tools cannot achieve precise centering and stable hovering, requiring repeated manual adjustments, which increases the difficulty of the operation and assembly time. To address this, we propose a single-hook wheel lifting tool. Utility Model Content

[0012] Technical problem solved: In view of the shortcomings of the existing technology, this utility model provides a single hook lifting device for wheels. It mainly uses a nut to lock the lifting device to enhance the safety of the wheel during transportation. Moreover, it has only a single hook, which is convenient for quick hooking and releasing. In terms of mechanical principle, the tighter it is pulled, the lifting load is directly converted into locking force, eliminating the risk of slippage, and can effectively solve the problems in the background technology.

[0013] Technical Solution: To achieve the above objectives, the technical solution adopted by this utility model is as follows: a wheel single hook lifting device, including a wheel hook, a lifting device baffle, a sleeve and a horizontal lifting rod, wherein the sleeve is fitted around the outer ring of the horizontal lifting rod, the lifting device baffle passes through the position between the sleeve and the horizontal lifting rod, a second round nut is positioned at one end of the outer wall of the horizontal lifting rod located at the sleeve, and a first round nut is positioned at the other end of the outer wall of the horizontal lifting rod located at the sleeve, wherein the horizontal lifting rod is positioned between the wheel hook.

[0014] Preferably, the outer wall of the horizontal lifting rod is provided with a second mounting groove, and the inner surface of the second mounting groove is positioned with a second sealing anti-slip pad. The outer wall of the sleeve is provided with a first mounting groove, and the inner surface of the first mounting groove is positioned with a first sealing anti-slip pad. The lifting baffle passes through the position of the first mounting groove and the second mounting groove. The end of the horizontal lifting rod is positioned with a mounting seat, and the end of the mounting seat is integrally formed with a mounting clip.

[0015] Preferably, the outer walls of the first round nut and the second round nut are integrally formed with grooves, the end of the lifting device baffle is integrally formed with a limit frame, and the end of the wheel hook is provided with a hook hole.

[0017] Preferably, the first round nut and the slot are integrally formed by die casting, the lifting device baffle and the limiting frame are integrally formed by die casting, and the lifting device baffle is engaged and limited by the limiting frame.

[0018] Preferably, the lifting device baffle passes through the horizontal lifting rod and is fixed to the sleeve, and the sleeve is fixed to the horizontal lifting rod by a first round nut and a second round nut.

[0019] Beneficial Effects: Compared with the prior art, this utility model provides a single-hook wheel lifting device with the following beneficial effects: This single-hook wheel lifting device mainly uses a nut to lock the lifting device, which enhances the safety of the wheel during transportation. With only a single hook, it is easy to quickly hook and release the wheel. Mechanically, it tightens as it is pulled, directly converting the lifting load into locking force, eliminating the risk of slippage. All contact points are on the inside of the rim and the non-working surface of the spokes, perfectly avoiding the tread and wheel flange. Simply place the lifting device inside the rim and then lift vertically to complete the grabbing. The entire single-hook wheel lifting device has a simple structure, is easy to operate, and performs better than traditional methods. Attached Figure Description
