Description

Technical Field

[0001] This utility model belongs to the field of rail vehicle maintenance technology, and in particular relates to a lifting device for rail vehicle maintenance. Background Technology

[0002] Maintenance of rail vehicles is of great importance to their safe operation. During long-term operation, various components of rail vehicles inevitably experience wear and fatigue. By conducting maintenance, potential problems can be identified and eliminated in a timely manner, thereby ensuring the safe operation of rail vehicles.

[0003] Rail vehicles are typically quite tall, so to facilitate maintenance personnel in inspecting them, maintenance platforms are usually installed on both sides of the vehicle being inspected for standing. These platforms often have multiple levels, as some maintenance tools need to be transported between these levels, and some rail vehicle components need to be replaced.

[0004] In the existing technology, overhead cranes are usually used to transport these maintenance tools or rail vehicle parts, which undoubtedly leads to a waste of resources. Moreover, the vehicle maintenance environment is relatively compact, and the overhead crane is prone to hitting the vehicle and maintenance platform, causing damage to the vehicle or maintenance platform, and may even lead to safety accidents.

[0005] Therefore, designing a lifting device with a simple structure and convenient operation is of great significance for the maintenance of rail vehicles. Utility Model Content

[0006] In view of the shortcomings of related technologies, this utility model provides a lifting device for the maintenance of rail vehicles, for transporting goods to be transported.

[0007] This utility model provides a lifting device for the maintenance of rail vehicles. The lifting device cooperates with a maintenance platform to perform maintenance on rail vehicles. The maintenance platform is defined by a vertically oriented clearance opening. The lifting device includes:

[0008] The column is installed vertically; the column passes through the clearance opening.

[0009] A winch is located at the top of a column. The winch is connected to a rope and is used to wind up or release the rope.

[0010] A cage is used to carry goods to be transported and / or maintenance personnel; the cage has openings on its perimeter walls for the goods to be transported and / or maintenance personnel to enter and exit the cage.

[0011] The winch retracts the rope, causing the cage to move upwards; the winch releases the rope, causing the cage to move downwards.

[0012] This technical solution increases the height of the winch by setting the column vertically and installing the winch on the top of the column, thus raising the winch a certain distance from the ground and enabling the winch to raise and lower the cage. By placing the column inside the clearance opening, it is convenient for the cage to pass through the clearance opening for raising and lowering, and at the same time, it can also support the column to a certain extent, preventing the column from tilting. This increases the stability and reliability of the vertical setting of the column, thereby increasing the safety and reliability of the lifting device.

[0013] In some embodiments, the columns are connected to a fence, and the columns and the fence together define a hollow shell. The cage is located inside the shell, and the shell has an opening that corresponds to the opening of the cage.

[0014] This technical solution uses a perimeter fence, which, together with the columns, forms a shell within which the hoisting cage is raised and lowered. This prevents maintenance personnel from accidentally entering the hoisting cage and also seals off any openings, preventing accidents caused by personnel accidentally entering these openings.

[0015] In some embodiments, the housing is connected to a door, which is rotatably positioned at the housing opening for opening or closing the housing opening.

[0016] This technical solution involves installing a door to seal the opening in the casing, thereby preventing maintenance personnel from accidentally entering the clearance opening or the hoist cage through the casing opening.

[0017] In some embodiments, the maintenance platform includes a multi-layer platform arranged vertically; multiple doors are provided, each corresponding to a multi-layer platform, and the doors are located above the corresponding platform.

[0018] In some embodiments, the housing is provided with guide rails located inside the housing and extending in a vertical direction; the outer periphery of the cage is provided with rollers that contact the guide rails and move along the guide rails.

[0019] This technical solution increases the reliability and stability of the cage's movement by setting guide rails on the shell and rollers on the outer periphery of the cage, and by using the rollers to move along the guide rails.

[0020] In some embodiments, four columns are provided, which are correspondingly located at the four corners of the housing; guide rails are provided on the columns.

[0021] In some embodiments, four guide rails are provided, with each guide rail corresponding to one of the four columns; four rollers are provided, with each roller corresponding to one of the four corners of the cage; and each roller corresponds to one of the four columns.

[0022] In some embodiments, the top of the housing is provided with an opening, and a mounting rod is provided at the top opening of the housing, to which the winch is mounted.

[0023] In some embodiments, the connection between the rope and the cage is located on the center line of the cage, which is set vertically.

[0024] In some embodiments, the cage includes a platform, a fence, and a lifting device. The bottom of the fence is connected to the platform, the fence extends along the outer perimeter of the platform, and the lifting device is located at the top of the fence and connected to a rope.

[0025] Based on the above technical solution, the lifting device for rail vehicle maintenance in this embodiment of the utility model can realize the transportation of goods to be transported and maintenance personnel, and the overall structure is simple, easy to operate and low in cost.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] As attached Figure 1 and Figure 2As shown in an illustrative embodiment of the lifting device for rail vehicle maintenance of this utility model, the lifting device for rail vehicle maintenance cooperates with the maintenance platform 5 to perform rail vehicle maintenance; the lifting device for rail vehicle maintenance includes a column 1, a winch 4, and a cage 7. The maintenance platform 5 is defined with a clearance opening, the opening direction of which is set vertically, and the clearance opening is used for the cage 7 to pass through the maintenance platform 5 for lifting; the column 1 is set vertically, and the column 1 is set inside or through the clearance opening; the winch 4 is set at the upper end of the column 1, and the winch 4 is connected to a rope 41, which is used to wind up or release the rope 41; the cage 7 is used to carry the goods to be transported and / or maintenance personnel; the peripheral wall of the cage 7 is provided with a cage opening for the goods to be transported and / or maintenance personnel to enter and exit the cage 7; wherein, the winch 4 winds up the rope 41, causing the cage 7 to move upward; the winch 4 releases the rope 41, causing the cage 7 to move downward.

[0045] It should be noted that the items to be transported include, but are not limited to, maintenance tools, new parts that need to be installed on rail vehicles, and old parts that need to be replaced.

[0046] It should also be noted that when the cage 7 moves upward, it moves upward under the tension of the rope 41; when the cage 7 descends, the rope 41 may not apply tension to the cage 7, allowing the cage 7 to fall under its own weight, or the rope 41 may apply tension to the cage 7, allowing the cage 7 to fall under the combined action of its own weight and the tension of the rope 41.

[0047] The aforementioned lifting device for rail vehicle maintenance increases the height of the winch 4 by setting the column 1 vertically and installing the winch 4 on the upper part of the column 1, so that the winch 4 is a certain distance from the ground, thereby enabling the winch 4 to lift the cage 7. By setting the column 1 in the clearance opening, on the one hand, it is convenient for the cage 7 to pass through the clearance opening for lifting and lowering, and on the other hand, it can also support the column 1 to a certain extent, preventing the column 1 from tilting, increasing the stability and reliability of the vertical setting of the column 1, thereby increasing the safety and reliability of the lifting device.

[0048] like Figure 1 and Figure 3 As shown, the upright column 1 is connected to the enclosure net 2. The upright column 1 and the enclosure net 2 together define a shell, which has an internally hollow structure. The shell has an opening that corresponds to the opening of the hoist cage 7, allowing maintenance personnel and / or items to be transported to enter and exit the hoist cage 7. By having the enclosure net 2 and the upright column 1 jointly define the shell and allow the hoist cage 7 to rise and fall within the shell, it can prevent maintenance personnel from accidentally entering the hoist cage 7. On the other hand, the enclosure net 2 can also close the avoidance opening, preventing maintenance personnel from accidentally entering the avoidance opening and causing a safety accident.

[0049] like Figure 1 , Figure 2 and Figure 5 As shown, the shell is connected to a door 3, which is rotatably positioned at the shell opening for opening or closing. The door 3 is used to seal the shell opening to prevent maintenance personnel from accidentally entering the clearance opening or the hoisting cage 7 through the shell opening.

[0050] like Figure 1 As shown, the maintenance platform 5 includes multiple platforms arranged vertically; multiple doors 3 are provided, each corresponding to a multi-level platform. The doors 3 are located above the corresponding platforms. When the items to be transported and / or maintenance personnel need to reach a certain platform, the corresponding door 3 is opened to allow the items to be transported and / or maintenance personnel to enter and exit the cage 7.

[0051] It should be noted that a support member 51 is provided between adjacent platform layers to ensure that there is a certain distance between adjacent platform layers in the vertical direction.

[0052] like Figure 4 As shown, the housing is provided with a guide rail 11, which is located inside the housing and extends vertically; the outer periphery of the cage 7 is provided with rollers 8, which are rotatably connected to the cage 7. The rollers 8 contact each other with the guide rail 11 and move along the guide rail 11 to guide the movement of the cage 7, thereby increasing the reliability and stability of the movement of the cage 7.

[0053] In some embodiments, four columns 1 are provided, and the four columns 1 are correspondingly arranged at the four corners of the housing; the guide rail 11 is provided on the columns 1. By providing four columns 1, the overall load-bearing capacity of the columns 1 is increased, thereby increasing the reliability of the lifting device's transportation operation.

[0054] Four guide rails 11 are provided, with each guide rail 11 corresponding to one of the four uprights 1; four rollers 8 are provided, with each roller 8 located near one of the four corners of the cage 7; each roller 8 corresponds to one of the four uprights 1. By providing four guide rails 11 and four rollers 8, the reliability and stability of the movement of the cage 7 are increased.

[0055] like Figures 1-3 As shown, the top of the housing has an opening, and a mounting rod 6 is provided at the top opening of the housing. The winch 4 is mounted on the mounting rod 6, and the rope 41 is located inside the housing.

[0056] It should be noted that the speed of the winch 4 can be adjusted. By adjusting the speed of the winch 4, the lifting speed of the cage 7 can be controlled. This is common knowledge in the field and will not be elaborated further.

[0057] like Figure 7As shown, the cage 7 includes a platform 71, a railing 72, and a lifting component 73. The platform 71 is used to place the items to be transported or for maintenance personnel to stand on. The railing 72 is used to protect the items to be transported and / or the maintenance personnel, preventing them from falling off the platform 71. The bottom of the railing 72 is connected to the platform 71, and the railing 72 extends along the outer perimeter of the platform 71. The lifting component 73 is located at the top of the railing 72 and is connected to the rope 41 so that the winch 4 can lift the cage 7 through the rope 41.

[0058] In some embodiments, the connection between the rope 41 and the lifting member 73 is located on the center line of the cage 7 arranged in the vertical direction, so that the cage 7 has only one lifting point, thereby allowing the cage 7 to be automatically balanced during transportation.

[0059] In some embodiments, the cage 7 is equipped with a gravity sensor to detect the total weight of the cage 7 and the items and / or maintenance personnel inside the cage 7, so as to avoid adverse consequences due to excessive total weight.

[0060] In other embodiments, the gravity sensor is connected to an alarm that sounds when the total weight of the cage 7 and the items and / or maintenance personnel inside the cage 7 exceeds a certain value, in order to alert the maintenance personnel.

[0061] The following section uses the example of maintenance platform 5, which includes three platforms, where the items to be transported need to be moved from the first platform to the third platform, to explain in detail the working principle of the lifting device used for the maintenance of rail vehicles.

[0062] The winch 4 releases the rope 41, allowing the cage 7 to be transported to the first platform under its own weight and / or the tension of the rope 41. The door 3 corresponding to the first platform is opened, and the items to be transported are placed into the cage 7 using a trolley or other equipment. Then, the winch 4 winds up the rope 41, and the cage 7 moves upward under the tension of the rope 41. As the cage 7 moves upward, the roller 8 moves upward along the guide rail 11. When the cage 7 is transported to the third platform, the winch 4 stops working, the door 3 corresponding to the third platform is opened, and the items to be transported are taken out of the cage 7.

[0063] The aforementioned lifting device for rail vehicle maintenance has a simple overall structure, low cost, and easy operation. The hoist 7 can be raised and lowered using only the winch 4, and the speed of the winch 4 can be adjusted according to usage requirements, thus solving the problem of cumbersome operation of the original equipment.

[0064] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0065] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
