Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a crane track hoisting device. Background Art

[0002] After long-term use, the rails will wear out. After wear, the rails are not strong enough, which poses a safety risk. The degree of rail wear varies, which will affect the normal driving of the vehicle.

[0003] Therefore, the rails need to be replaced after they are worn. When replacing the rails, the rails must be raised first, and then the wire ropes must be passed under the rails to tie them up. At the same time, the crane must be operated very slowly during hoisting, otherwise the rails will easily lose balance, causing collisions and slippage, which is a high risk.

[0004] Therefore, how to improve the lifting efficiency of the traveling rail and reduce the danger during lifting has become a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0005] In order to solve the technical problems in the background technology, the utility model discloses a vehicle track hoisting device.

[0006] The utility model provides a vehicle track hoisting device, comprising two clamping plates arranged symmetrically and installed at both ends of the track;

[0007] The card plate is provided with a card slot for clamping the head of the rail;

[0008] The lifting rope is fixedly connected to the pallet.

[0009] When the rail needs to be replaced, first connect the slot to the head of the rail, and then use the lifting rope to lift the rail through the pallet, thus eliminating the process of raising the rail, and the operation is simple and convenient; and the pallet is set to be two symmetrically arranged pieces, so that the rail is evenly stressed and always in a horizontal state, not easy to lose balance, and the danger is reduced.

[0010] In order to improve the structural stability of the card board connected to the rail, a further design is that the shape of the card slot is contoured with the shape of the rail head.

[0011] The lifting rope is directly connected to the pallet, which is difficult to operate. Based on this, a further design is: a shackle is connected to the upper end of the pallet, and the lifting rope is connected to the shackle. In this way, the lifting rope and the shackle are always in a connected state. Only the pin on the shackle needs to be disassembled and assembled to achieve the connection or separation of the shackle and the pallet, which is simple and convenient to operate. Moreover, the assembly composed of the lifting rope and the shackle can also be used to lift other objects with lifting holes, which is more practical.

[0012] Since the lifting rope forms an inverted V shape, it is easy to drive the pallets to move towards each other during lifting, causing the rail to lose balance. Based on this, a further improvement is that a limit plate is also connected to the pallet to abut against the end of the rail. The specific structure of the limit plate is: the limit plate is L-shaped, its horizontal part is welded to the pallet, and its vertical part abuts against the end of the rail.

[0017] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0018] Embodiment 1:

[0019] like Figure 1 and Figure 2 As shown, the utility model discloses a vehicle track hoisting device, comprising two clamping plates 1 arranged symmetrically and installed at both ends of a track 2.

[0020] A slot 3 is provided at the lower end of the card plate 1 for clamping the head of the rail 2 to achieve the connection and fixation between the card plate 1 and the rail 2. The slot 3 is shaped like the head of the rail 2 to improve the structural stability of the clamping of the card plate 1 and the rail 2.

[0021] A lifting hole is provided at the upper end of the card plate 1, the shackle 5 is connected to the lifting hook, and the lifting rope 4 is connected to the U-shaped rod on the shackle 5. With such a configuration, the shackle 5 can be connected or separated from the card plate 1 by only disassembling the pin on the shackle 5, which is simple and convenient to operate. Moreover, the lifting rope 4 and the shackle 5 are always in a connected state, and the assembly formed by them can also be used to lift other objects with lifting holes, which is more practical.

[0022] When the rail 2 needs to be replaced, the slot 3 is first engaged with the head of the rail 2, and then the lifting rope 4 is used to lift the rail 2 through the clamping plate 1, thereby eliminating the process of raising the rail 2, and the operation is simple and convenient; and the clamping plates 1 of the rail 2 are set to be two symmetrically arranged pieces, so that the rail 2 is balanced in force and is always in a horizontal state, is not easy to lose balance, and reduces the danger.

[0023] Embodiment 2:

[0024] Compared with the first embodiment, the difference is that a limit plate 6 is also connected to the card plate 1. The limit plate 6 is composed of a horizontal part and a vertical part arranged vertically. The horizontal part is welded to the card plate 1, and the vertical part is against the end of the rail 2 to limit the card plate 1, so as to prevent the card plate 1 from moving toward each other under the tension of the suspension rope 4 and destroying the balance of the rail 2. Moreover, the card plate 1 has a tendency to move toward each other under the tension of the suspension rope 4, but is blocked by the limit plate 6, so that when the rail 2 is hoisted, the position of the card plate 1 is more stable, and the hoisting of the rail 2 is also more stable.

[0025] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
