Description

Technical Field

[0001] This utility model relates to the field of rail vehicle door systems, and more particularly to a transfer device for unlocking steel wire ropes. Background Technology

[0002] The existing rail vehicle door system unlocking device uses a double-groove pulley structure, which connects the in-vehicle emergency unlocking device and the external unlocking device respectively through a wire rope sleeve assembly. Due to space limitations, the unlocking device can only be set with a single-groove structure, and cannot connect the in-vehicle emergency unlocking device and the external unlocking device at the same time. Replacing the unlocking device requires disassembling both the in-vehicle emergency unlocking device and the external unlocking device, resulting in a large amount of maintenance work.

[0003] Therefore, it is necessary to develop a new type of adapter to solve the problem that the single-groove pull-wheel unlocking device cannot be connected to both the in-vehicle emergency unlocking device and the external unlocking device at the same time. Utility Model Content

[0004] Purpose of the utility model: To address the shortcomings and defects of the existing technology, this utility model provides a conversion device for unlocking steel wire ropes, solving the problem that the single-groove pulley unlocking device cannot simultaneously connect the in-vehicle emergency unlocking device and the external unlocking device; shortening the length of the unlocking device and saving space; and eliminating the need to disassemble the in-vehicle emergency unlocking device and the external unlocking device when replacing the unlocking device, thus reducing maintenance workload.

[0005] Technical solution: The present invention provides a transfer device for unlocking steel wire rope, characterized in that: it includes a transfer device, wherein the swing arm of the transfer device rotates around the central axis, one end of the swing arm has a hole for connecting the transfer steel wire rope, and the other end of the swing arm has two holes for connecting the outer operating steel wire rope and the inner operating steel wire rope respectively; the transfer steel wire rope is connected to the single-groove pull wheel of the unlocking device.

[0006] The swing arm is sleeved on the shaft in the middle and rotates around the shaft as the center of rotation.

[0007] The single-groove pull wheel, unlocking device, and lead screw are connected to each other.

[0008] The adapter wire rope is connected to the adapter wire rope assembly.

[0009] The adapter is fixed on the load-bearing drive mechanism.

[0010] The load-bearing drive mechanism is located on the rail vehicle door system.

[0011] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: The present invention solves the problem that the single-groove pull-wheel unlocking device cannot simultaneously connect the in-vehicle emergency unlocking device and the external unlocking device; it shortens the length of the unlocking device and saves space; when replacing the unlocking device, it is not necessary to disassemble the in-vehicle emergency unlocking device and the external unlocking device, thus reducing maintenance workload.

[0012] Figure 1 This is a schematic diagram of the structure of this utility model;

[0013] Figure 2 This is a top view of the structure of this utility model;

[0014] In the diagram, 1 is the swing arm; 2 is the shaft; 3 is the adapter; 4 is the lead screw; 5 is the single-groove pulley; 6 is the unlocking device; 7 is the external operating wire rope; 8 is the internal operating wire rope; and 9 is the adapter wire rope assembly. Detailed Implementation

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] The present invention relates to a transfer device for unlocking steel wire rope, comprising a transfer device 3, wherein a swing rod 1 of the transfer device 3 rotates around a central shaft 2, one end of the swing rod 1 is provided with a hole for connecting the transfer steel wire rope, and the other end of the swing rod 1 is provided with two holes for connecting the outer operating steel wire rope 7 and the inner operating steel wire rope 8 respectively; the transfer steel wire rope is connected to the single-groove pull wheel 5 of the unlocking device 6.

[0017] In this invention, the swing arm 1 is sleeved on the shaft 2 at its middle, and rotates around the shaft 2 as the center of rotation. The single-groove pulley 5 and the unlocking device 6 are connected to the lead screw 4. The adapter wire rope is connected to the adapter wire rope assembly 9. The adapter device 3 is fixed to the load-bearing drive mechanism. The load-bearing drive mechanism is located on the rail vehicle door system.

[0018] When operating the emergency unlocking device inside or outside the vehicle, pull the external or internal operating wire rope. The external or internal operating wire rope will drive the swing arm to rotate. The other side of the swing arm will pull the adapter wire rope, thereby driving the pull wheel of the unlocking device to rotate, thus achieving the purpose of unlocking.

[0019] If the unlocking device needs to be replaced, only the adapter wire rope assembly needs to be disassembled, without having to remove the emergency unlocking device inside the vehicle or the unlocking device outside the vehicle, thus reducing maintenance workload.

[0020] This invention solves the problem that the single-groove pull-wheel unlocking device cannot simultaneously connect the in-vehicle emergency unlocking device and the external unlocking device; it shortens the length of the unlocking device, saving space; and it eliminates the need to disassemble the in-vehicle emergency unlocking device and the external unlocking device when replacing the unlocking device, reducing maintenance workload.
