[0002] In the field of railway locomotives, locomotives need to be repaired in an advanced manner, because the locomotive main line cables, plug connectors, etc. need to be completely disassembled and repaired. However, due to the installation method of the main line of the Harmony locomotive, the main line cable needs to be removed from the socket before it can be disassembled and removed from the vehicle. However, the main line socket is currently facing problems such as difficulty in disassembly, low disassembly efficiency, and high disassembly damage rate. Therefore, a reasonable and simple main line socket needle removal device is particularly important. In the prior art, a sledgehammer is generally used to strike the needle remover, and the needle remover knocks the pin out of the socket. The defect is that the damage rate of the socket and the pin when disassembled using the old needle remover is high; multiple people are required to operate, the disassembly time is long, and the labor efficiency is low; the working space is narrow and the labor intensity is high, and there are safety hazards.

[0005] The needle withdrawal unit includes a threaded rod and a positioning push pin. The threaded rod passes through the nut. The lower end of the threaded rod is rotatably connected to the upper end of the positioning push pin through a bearing. The longitudinal cross-section of the positioning push pin is T-shaped. The lower end of the positioning push pin can penetrate into the hole of the pin on the locomotive. The outer diameter of the upper end of the positioning push pin is larger than the inner diameter of the hole of the pin.

[0006] Optionally, a handle is provided on the threaded rod.

[0007] Optionally, a rubber pad is provided on the downwardly facing surface of the raised portion on the side of the positioning push pin.

[0008] The advantages and positive effects of the present invention are: due to the adoption of the above technical scheme, the structure is simple, light and easy to operate; it is suitable for the needle withdrawal work of the locomotive main line socket; the operation is safe and firm, without safety hazards; it is suitable for a variety of vehicle models; the structure is simple and the cost is low.

DETAILED DESCRIPTION

[0013] The present invention is further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. In the description of the present invention, it should be understood that the orientation or position relationship indicated by the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a connection between the two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0014] As shown in the figure, the present invention provides a needle withdrawal device for the main line socket of a harmonious locomotive, comprising a needle withdrawal unit 2 and a bracket 3, the bracket 3 comprising an upper plate 3-2 and a lower plate 3-4, the upper plate 3-2 and the lower plate 3-4 are connected by a plurality of support plates 3-3, the upper plate 3-2 has a first circular hole, the first circular hole has a nut 3-1 coaxial with the first circular hole, the lower plate 3-4 has a second circular hole 3-5, the second circular hole 3-5 is coaxial with the first circular hole, and the lower plate 3-4 has a mounting hole for fixing the needle push device of the present invention to the locomotive body socket through a bolt 4;

[0015] The needle withdrawal unit 2 includes a threaded rod 2-1 and a positioning push pin 2-4. The threaded rod 2-1 passes through the nut 3-1. The lower end of the threaded rod 2-1 is rotatably connected to the upper end of the positioning push pin 2-4 through a bearing 2-3. The longitudinal cross-section of the positioning push pin 2-4 is T-shaped. The lower end of the positioning push pin 2-4 can penetrate into the hole of the pin 5 on the locomotive socket. The outer diameter of the upper end of the positioning push pin 2-4 is larger than the inner diameter of the hole of the pin 5.

[0016] A handle 1 is provided on the threaded rod 2-1 to facilitate the rotation of the threaded rod 2-1.

[0017] A rubber pad 2-5 is provided on the downwardly facing surface of the convex part of the side of the positioning push pin 2-4.

[0018] When the above-mentioned Harmony locomotive main line socket pin extraction device is used, firstly, the lower plate 3-4 of the bracket 3 on the device is placed on the socket of the locomotive body, and the device is fixed to the socket of the locomotive body by bolts 4. At this time, the handle 1 is turned clockwise to drive the threaded rod 2-1 to rotate, and the threaded rod 2-1 moves downward under the action of the nut 3-1, driving the lower part of the positioning push pin 2-4 to extend into the hole of the pin 5. When the convex part on the side of the positioning push pin 2-4 contacts the top surface of the pin 5, the threaded rod 2-1 continues to move downward so that the positioning push pin 2-4 pushes the pin 5 out of the socket. The handle 1 is turned counterclockwise to move the threaded rod 2-1 upward, and the positioning push pin 2-4 is pushed out of the socket. The entire device can be removed from the socket by disassembling the bolts 4.
