Description

Technical Field

[0001] This utility model relates to the technical field of remote-controlled electric marking equipment with hook tail frame. Background Technology

[0002] The coupler and coupler tail frame are core components of railway vehicle connecting devices, responsible for mechanical coupling, buffering, and traction force transmission between vehicles. The force transmission path is as follows: traction force is transmitted from the coupler → coupler tail pin → coupler tail frame → buffer → car body underframe, while impact force is transmitted in the opposite direction and absorbed by the buffer.

[0003] Therefore, the maintenance of hook tail frames is quite common during the repair process. After maintenance, the hook tail frames need to be marked. Currently, the maintenance marking of hook tail frames is done manually by holding a spray paint can and using a hollowed-out letter template. During the spraying process, the operator needs to be close to the workpiece conveyor belt, which poses a serious safety hazard on the assembly line. At the same time, the spray paint can cause damage to the operator's respiratory system. Therefore, based on the technical improvement requirements for safe production and employee health, this electric marking machine was invented. Utility Model Content

[0031] 600 slider, 610 planetary geared micro motor. Detailed Implementation

[0032] The remote-controlled electric marking device for the hook-tail frame consists of a workpiece conveying platform 100, a mounting bracket 200, a marking module 300, an electric telescopic rod 400, and a magnetic proximity switch 500. The mounting bracket 200 is a height-adjustable gantry structure. Two columns of the gantry are respectively installed on the foundations on both sides of the workpiece conveying platform 100, spanning the workpiece conveying platform and forming a gantry structure on the workpiece conveying platform.

[0033] In this embodiment, the workpiece conveying platform 100 can be a chain conveying platform or an intermittent step conveying platform, both of which are within the protection scope of this utility model and are used for conveying the hook tail frame.

[0034] A crossbeam 210 is installed at the upper end of the gantry frame. The two ends of the crossbeam 210 are installed at the ends of the gantry frame in an adjustable manner. Specifically, a square sleeve is installed at the end of the crossbeam 210. The square sleeve is fitted onto the column, and the end of the crossbeam is fixed at a reasonable height position of the column by the locking screw of the square sleeve. If necessary, the height of the crossbeam can be adjusted by loosening the locking screw.

[0035] Furthermore, a bracket 510 is fixedly suspended on the aforementioned crossbeam 210 for mounting a magnetic proximity switch 500. This magnetic proximity switch uses a built-in displacement sensor to sense the positional movement of the proximity hook tail frame, thereby controlling the pause of the workpiece conveying platform. During the pause interval, marking is performed on the surface of the hook tail frame. The sensing distance of the aforementioned magnetic proximity switch is adjusted to approximately 30 mm.

[0036] A portion of the crossbeam 210 is toothed, forming a partial rack structure 211. A slider 600 is fitted onto the crossbeam, and a pinion gear is installed in the slider, meshing with the rack structure of the crossbeam. A planetary geared micro motor 610 is mounted on the slider. The output shaft of the planetary geared micro motor is connected to the pinion gear via a bevel gear transmission mechanism. Driven by the planetary geared micro motor 610, the slider moves along the length of the crossbeam, thereby adjusting the position of the slider 600.

[0037] An electric telescopic rod 400 is fixedly installed on the aforementioned slider 600 by a hoisting method. The lower end of the electric telescopic rod 400 is fixedly installed with a mounting plate 410 via a plug-in connection. The mounting plate 410 is a flat plate with a slot structure on one side formed by a U-shaped bend. A marking module 300 is installed below the mounting plate via a buffer structure. The buffer device is a rubber pad (not shown in the figure). Specifically, during the marking process, the rubber pad buffers the movement of the marking module, reducing wear on the marking module.

[0038] The marking module 300 described above has a hollow structure with a mounting section on its side. The mounting section has screw holes 310 for engaging with the aforementioned slot structure and securing it with screws. This detachable structure facilitates the replacement and maintenance of the marking module. The marking module includes an ink storage cavity 320, into which ink is filled. This ink storage cavity has a stepped inner cavity, and an ink filling hole and a cap 330 are located at the highest point of the ink storage cavity to facilitate subsequent ink filling. The stepped ink storage cavity has an ink cotton pad mounting cavity below it, into which an ink cotton pad 340 is installed. The ink cotton pad 340 contains a high-hardness pad, and a side cap 350 is located on the outside of the ink cotton pad for replacement. The ink cotton pad and the mounting cavity are engaged by a laterally positioned triangular interlocking structure 360, achieving a fixed installation of the ink cotton pad.

[0039] A date patch 370 is attached to the lower surface of the ink cotton pad. This date patch has bent portions formed by bending the edges at both ends. Correspondingly, an oblique slot 371 is provided on the lower surface of the marking module housing. The date patch is installed by engaging the bent portions within the oblique slot. In this embodiment, the date patch is made of high-molecular-weight plastic, possessing a certain degree of tension and elasticity, and can be securely adhered to the lower surface of the ink cotton pad under the action of ink molecular forces.

[0040] The date stickers mentioned above use a cutout method to form numbers, indicating the marked date.

[0041] A sponge block 380 is placed inside the ink storage cavity. The sponge block has an n-shaped profile, with one end positioned inside the ink storage cavity and the other end passing through the connecting channel between the ink storage cavity and the ink cotton pad mounting cavity, and abutting against the ink cotton pad inside the mounting cavity. After abutting, the sponge block absorbs and exports the ink inside to the ink cotton pad. The date sticker is attached to the lower surface of the ink cotton pad, thus realizing the function of exporting the ink in the ink storage cavity and transporting it to the date sticker position. The ink is transferred to the surface of the hook tail frame by the overall downward pressure of the marking module, thereby realizing marking.

[0042] The top of the aforementioned sponge block extends to one side of the ink storage cavity to absorb the ink in the cavity, thereby achieving the adsorption and guidance of the ink.

[0043] This device can be installed in a suitable location on an assembly line. As the hook tail frame moves forward, a magnetic proximity switch automatically starts, stops, and marks the hook tail frame. After marking, the workpiece conveyor module is triggered to continue conveying, achieving accurate marking (date). Furthermore, workers no longer need to enter the assembly line; the entire operation can be completed remotely from their workstation. This device has been tested and the results are excellent, demonstrating precise spraying, high efficiency, simple installation, and strong adaptability.

[0044] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Without departing from the spirit of the present utility model, all modifications and improvements to the present utility model by those skilled in the art should fall within the protection scope defined by the claims of the present utility model.
