Description

Technical Field

[0001] The utility model relates to the technical field of rail transit vehicle coupler connection auxiliary tooling, in particular to a fixing device for a high-speed rail motor vehicle coupler electrical connection plug. Background Art

[0002] During the EMU commissioning phase, there is a test called the reconnection test, which aims to verify the reconnection function of two short-length EMUs. The electrical connection is completed by the automatic couplers of the adjacent head cars of the two EMUs. The automatic couplers are composed of mechanical couplers and electrical couplers. The electrical couplers are installed on the mechanical couplers, and the reliability of the electrical connection is guaranteed by the connection of the mechanical couplers. Figure 1 , Figure 2 As shown, Figure 1 This is the state before reconnection. Figure 2 This test requires two EMUs of the same model to complete. In actual production practice, it is difficult to meet the conditions for two EMUs at the same time. Therefore, a simulator is used to replace another EMU in the commissioning process to complete the test to verify the reconnection performance of the vehicle. The simulator has two electrical coupler connectors that match the actual vehicle, such as Figure 3 As shown, there is no support and fixation of the mechanical hook. Since the electrical hook connector is heavy and large in size, it needs to be fixed separately to ensure the reliability of the electrical connection. There are two fixing schemes in the prior art. One is to use thick rubber bands to bind and fix the two electrical hooks, and the other is to use metal clamps (such as F-type clamps) to fix. The former will cause the electrical hook to be insufficiently stressed due to the elasticity of the rubber band and easy to loosen, while the latter will cause uneven stress on the contact surface, which is easy to damage the paint surface and even the internal plastic core.

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] See also Figure 4 As shown;

[0032] The utility model discloses a fixing device for a high-speed train coupler electrical connection plug, comprising: two device bodies 1;

[0033] The device body 1 is a plate-shaped structure, and two device bodies 1 can be symmetrically arranged on both sides of the simulator electrical coupler connector 100;

[0034] The device body 1 is equipped with a quick-release part 2, which is connected and disassembled with the simulator electrical coupler connector 100 through the quick-release part 2. A bending part 3 is formed on the end of the device body 1 away from the simulator electrical coupler connector 100. The bending part 3 is equipped with a driving component. The driving component has a retractable push rod 4. When the bending part 3 is hooked and connected with the EMU electrical coupler connector 200, the push rod 4 is extended to push the EMU electrical coupler connector 200 and the simulator electrical coupler connector 100 to plug in, thereby realizing the clamping and fixation between the simulator and the real EMU electrical coupler during the reconnection test of the simulator and the real EMU, so that the two connectors are closely connected. The device adopts the push rod 4 of the driving component to push the direct contact device of the two couplers to clamp, thereby achieving the purpose of improving the contact of the electrical connector and reducing the damage to the paint surface and the core of the electrical coupler connector.

[0035] In a preferred embodiment, the driving component includes a push rod 4 and a driver for providing driving force for the push rod 4. Specifically, the driver is a small cylinder 5, the piston rod of the cylinder 5 is fixedly connected to the push rod 4, and the power source of the push rod 4 is provided by the cylinder 5. Of course, the driver can also be an oil cylinder or other device capable of providing driving force in the prior art, which can provide thrust for the push rod 4;

[0036] See also Figure 4 As shown, preferably, the pressure of the cylinder 5 is less than 1 bar, and specifically the pressure of the cylinder 5 is 0.5 bar. When in use, the cylinder 5 is installed on the bending portion 3, and the cylinder 5 is connected to the external air circuit system. A pressure limiting valve (not shown) is used to limit the compressed air to 0.5 bar, so as to ensure sufficient thrust while preventing the cylinder 5 from damaging the electric coupler due to excessive thrust. When there is no compressed air, the cylinder 5 drives the push rod 4 to retract, and occupies a small volume. When compressed air enters, the cylinder 5 is filled with air, and the cylinder 5 drives the push rod 4 to extend, pushing the EMU electric coupler connector 200 to move, and maintaining a certain thrust to maintain the connector contact;

[0037] In order to prevent the push rod 4 of the cylinder 5 from being hard-connected and damaging the EMU electrical coupler connector 200, an elastic layer is installed on the surface of the push rod 4 for protection, and the push rod 4 contacts the EMU electrical coupler connector 200 through the elastic layer. The elastic layer is a rubber sleeve in the prior art, and of course it can also be other flexible sheaths. The working principles of the device body 1 on both sides are the same, and the principles on the other side are not repeated here one by one. When it is necessary to disconnect the electrical connection of the coupler, press the air pump pressure relief valve (not shown) in the air circuit system, and the exhaust of the cylinder 5 drives the push rod 4 to retract. The device can be removed from the simulator electrical coupler and prepared for the next test;

[0038] See also Figure 5As shown, preferably, the device body 1 is provided with a slide groove 6 slidably connected to the quick release part 2 along the length direction, and the size parameters of the slide groove 6 are 6 cm in length and 1 cm in width; the position of the quick release part 2 on the device body 1 is positioned by the slide groove 6, and the quick release part 2 is a butterfly bolt, which is easy to use. During assembly, the quick release part 2 is connected and fixed to the simulator electrical car coupler connector 100 through the slide groove 6. In addition, through the slide groove 6, according to the different sizes of the simulator electrical car coupler and the EMU car coupler of different vehicle models, the size can be adjusted forward and backward until the quick release part 2 reaches the best use state;

[0039] The simulator electrical coupler connector 100 has two screw holes, which are fixedly connected by the screw holes in cooperation with butterfly bolts, so that the device body 1 can be installed and fastened on the simulator electrical coupler connector 100. At the same time, the length can be adjusted by the two butterfly bolts in cooperation with the slide groove 6 to adapt to different vehicle models.

[0040] See also Figure 4 As shown, preferably, the device body 1 is a high-strength steel sheet. Specifically, the size parameters of the device body 1 are a length of 38 cm, a width of 4 cm, and a thickness of 2 mm. When an external force is applied, the steel sheet has a certain deformation elasticity in the lateral direction, and the steel sheet returns to its original position after the external force disappears.

[0041] See also Figure 5 As shown, preferably, the angle between the bending portion 3 and the device body 1 is not greater than 90°, preferably 90°, the length of the bending portion 3 is 4 cm, and a reinforcing structure 7 is provided at the connection between the bending portion 3 and the device body 1, and the reinforcing structure 7 is a triangular rib plate. The function of the bending portion 3 is to hook the connector from the rear of the EMU electrical connector 200 to prepare for the subsequent connector fixation. A small triangular rib plate is provided at the root of the bending portion 3, which can effectively enhance the structural strength.

[0042] In the above technical solution, the utility model provides a fixing device for a high-speed train coupler electrical connection plug, the working principle of which is:

[0043] This fixing device is suitable for the case where the electric coupler is arranged on both sides of the mechanical coupler;

[0044] Specific implementation measures, taking a certain type of EMU as an example, the EMU coupler electrical connector is distributed on both sides. During the reconnection test, the electrical coupler of the vehicle reconnection simulator of this type of vehicle is connected to the electrical coupler of the EMU by means of an anti-misinsertion device to maintain basic connection;

[0045] like Figure 5As shown, the device body 1 is installed on the simulator electrical coupler connector 100 using a butterfly bolt passing through the slide slot 6. The device body 1 is adjusted by adjusting the position of the slide slot 6 to ensure that the end of the push rod 4 of the cylinder 5 contacts the rear of the EMU electrical coupler connector 200, but the force of the push rod 4 is not applied to the EMU electrical coupler connector 200, and there is a certain gap between the two electrical coupler connectors.

[0046] like Figure 5 As shown, after the preparation work is completed, the cylinder 5 is filled with air, and the push rod 4 of the cylinder 5 is pushed out after being filled with air through the pressure-limiting valve. The two electric hooks are pulled to move relative to each other through the device body 1, so that the two electric hooks maintain a certain squeezing pressure to ensure the contact of the internal pins of the electric hooks, thereby achieving the purpose of using the device.

[0047] After the test is completed, the air is exhausted through the air pump, the push rod 4 is retracted, and the two electrical couplers lose their supporting force and wait for separation. The plug fixing device is removed and the electrical connection between the simulator and the vehicle is disconnected.

[0048] The fixing device of the electrical connection plug of the high-speed train coupler is used for clamping and fixing the electrical couplers of the simulator and the real EMU during the reconnection test between the simulator and the real EMU, so that the two connectors are tightly connected. Compared with the prior art, the fixing device adopts the push rod of a small cylinder as a direct contact device to push the two couplers to clamp, thereby achieving the purpose of improving the contact of the electrical connector and reducing the damage to the paint surface and the plug core of the electrical coupler connector.

[0049] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
