Description

Technical Field

[0001] The utility model relates to the technical field of rail transportation maintenance, in particular to a coupler auxiliary disassembly and assembly device. Background Art

[0002] Rail vehicles are an important transportation link connecting cities, and have gradually become the main means of transportation within cities. Rail vehicles are also the main carrier for freight transportation. Rail vehicles are composed of multiple carriages connected in series. Couplers are provided at both ends of each carriage, and adjacent carriages are connected by couplers. At present, when connecting the coupler to the carriage, it is usually necessary to first calibrate the position of the coupler relative to the carriage. When calibrating the position of the coupler, one way is to use a forklift. Specifically, an operator drives the forklift as a driver and lifts the coupler connected to the forklift to a preset installation height; the other operator needs to observe the relative position between the coupler and the carriage installation position, and verbally inform the driver of the observed position information. The driver calibrates the position of the coupler based on the position information until the coupler is aligned with the carriage installation position. The alignment process requires the cooperation of two people, and the process is relatively cumbersome. Another way is to achieve it through a special coupler installation tool. The technical solution with publication number CN211466311U discloses a coupler installation tool. Although it can realize the lifting and lowering of the coupler and the adjustment of the horizontal direction when used, it cannot realize the adjustment of the coupler angle. When the coupler is installed on the carriage, the angle needs to be adjusted manually many times. The alignment process is relatively laborious and the alignment efficiency is low.

An adjustment slider 29 that cooperates with the adjustment rails 28 is correspondingly installed on the first frame 201. The sliding connection between the first frame 201 and the second frame 202 can realize axial movement of the coupler 25 during disassembly and assembly, without moving the car body 1, thereby facilitating the disassembly and assembly of the coupler 25.

[0033] In order to achieve the adjustment of the coupler 25 in the vertical direction, horizontal direction and various angles, the device is correspondingly designed with a lifting mechanism, a horizontal adjustment mechanism 6, a front and rear angle adjustment mechanism 4 and a left and right angle adjustment mechanism 5.

The lifting support plate 10 is installed on the lifting bracket 9 along the vertical sliding direction. The lowering support plate 10 and the lifting bracket 9 are both slidably connected via rollers 24, and grooves for accommodating the rollers 24 are provided on the inner side of the guide frame 7 and the lifting bracket 9. When in use, the lifting bracket 9 is driven to slide by controlling the linear actuator 11 to achieve rough positioning. The sliding connection between the lifting support plate 10 and the lifting bracket 9 is provided to facilitate fine-tuning through the lifting support plate 10. The lifting support plate 10 can be lifted by manpower or auxiliary equipment. The linear actuator 11 in this embodiment is a device such as an electric cylinder or a pneumatic cylinder that can directly generate linear motion.

[0036] In order to achieve horizontal movement: a support plate 16 is horizontally slidably installed on the lifting support plate 10 of the lifting mechanism, and a horizontal guide rail 22 is provided on the side of the lifting support plate 10 away from the linear actuator 11. The support plate 16 is slidably installed on the horizontal guide rail 22 through a horizontal slider 23. The horizontal adjustment mechanism 6 is a matching structure of a screw rod and a nut seat. Specifically: a second screw rod 601 is rotatably installed on the lifting support plate 10, and a second nut seat matching the second screw rod 601 is fixedly installed on the support plate 16. A second hand wheel 602 is fixedly installed on the outer end of the second screw rod 601. By rotating the second hand wheel 602, the support plate 16 can be made to slide on the horizontal guide rail 22, thereby realizing the horizontal adjustment of the coupler 25.

[0037] In order to achieve left-right angle adjustment of the coupler 25: the support frame 2 is rotatably mounted on the support plate 16 via the central shaft 17, and a left-right angle adjustment mechanism 5 is provided between the support frame 2 and the support plate 16; the left-right angle adjustment mechanism 5 includes an auxiliary guide rail 19, an auxiliary slider 20, a sliding block 501 and a third screw rod 503, the third screw rod 503 is rotatably mounted on the support frame 2, the sliding block 501 is cooperatively mounted on the third screw rod 503, the sliding block 501 is fixedly connected to the auxiliary slider 20, the auxiliary slider 20 is slidably mounted on the auxiliary guide rail 19, and the auxiliary guide rail 19 is fixedly mounted on the support frame 2; the corresponding sliding block 5 on the support frame 2 01 is provided with a notch, and an adjusting shaft 30 is provided at the corresponding notch on the support plate 16.

An adjusting groove 502 cooperating with the adjusting shaft 30 is provided on the sliding block 501; a third hand wheel 504 is fixedly installed at both ends of the third screw rod 503; the principle is: by rotating the third hand wheel 504, the movement of the sliding block 501 is realized, and since the adjusting groove 502 is provided on the sliding block 501, the movement of the slider is converted into a deflection motion of the support frame 2 under the cooperation between it and the adjusting shaft 30, thereby realizing the left and right angle adjustment of the coupler 25.

[0038] In order to prevent the support frame 2 from sagging due to insufficient supporting force when supporting the coupler 25, a waist-shaped adjustment hole 21 is opened on the first frame 201 above the central rotating shaft 17, and a clamping bolt 18 is installed in the waist-shaped adjustment hole 21. The clamping bolt 18 passes through the waist-shaped hole and is fixedly connected to the support plate 16. The setting of the waist-shaped adjustment hole 21 and the clamping bolt 18 can not only limit the rotation angle of the support frame 2, but also press the support frame 2 on the support plate 16 to prevent the support frame 2 from sagging.

[0039] In order to achieve control of the entire device, a controller is installed on the guide frame 7. The motor and the handlebar linear actuator 11 are electrically connected to the controller. A battery is installed at the bottom of the corresponding vehicle body 1. By turning the speed control handle on the handlebar 8, the speed of the motor can be controlled, driving the power wheel 102 to rotate and realizing the movement of the entire device.
