[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] This utility model provides a track joint grinding device. Please refer to [link / reference]. Figure 1-Figure 4The system includes a track 100, a support frame 200, and a first linear motor 300. The support frame 200 has a slot 210 at its bottom, through which it is secured to the track 100. First electric push rods 220 are symmetrically mounted on both sides of the support frame 200. A clamping plate 230 is slidably connected within the slot 210. One end of each first electric push rod 220 is fixedly connected to the clamping plate 230. The first linear motors 300 are fixedly mounted on the top of the support frame 200, and the moving ends of the two first linear motors 300 are fixed. A second linear motor 310 is connected, and a second electric push rod 320 is fixedly mounted on the moving end of the second linear motor 310. A mounting bracket 330 is fixedly mounted on one end of the second electric push rod 320. A grinding motor 340 is embedded in the mounting bracket 330. Rotating rods 350 are connected to both sides of the grinding motor 340. The grinding motor 340 and the inner wall of the mounting bracket 330 are rotatably connected through the rotating rods 350. A rotary motor 360 is fixedly mounted on the side wall of the mounting bracket 330. The rotating shaft of the rotary motor 360 is connected to the rotating rod 350. One end is connected to the shaft of the grinding motor 340, which is connected to a grinding disc 370. Specifically, the support frame 200 is easily engaged with the track 100 via the slot 210, and the clamping plate 230 is easily pushed by the first electric push rod 220, so that the clamping plate 230 is clamped on both sides of the track 100, which facilitates fixing the grinding device on the track 100. Through the cooperation of the first linear motor 300 and the second linear motor 310, the grinding disc 370 is driven to move laterally and longitudinally, which facilitates the adjustment of the grinding disc 370. The position is adjusted by using the second electric push rod 320 to push the mounting bracket 330 to adjust the distance between the grinding disc 370 and the joint of the track 100. The rotary motor 360 drives the rotating rod 350 to rotate, which in turn drives the grinding motor 340 to rotate, making it easy to adjust the grinding disc 370 to a horizontal or vertical position. The horizontal grinding disc 370 is convenient for grinding the horizontal surface of the track 100 joint, and the vertical grinding disc 370 is convenient for grinding the vertical surface of the track 100 joint.

[0027] The support frame 200 has a control panel on its side wall. The control panel is electrically connected to the first electric push rod 220, the first linear motor 300, the second linear motor 310, and the second electric push rod 320. Specifically, the control panel facilitates the operation of the device and makes grinding easier.

[0028] Lights are provided on both the front and rear sides of the second linear motor 310. The lights are fixedly connected to the front and rear sides of the second linear motor 310 by bolts. Specifically, the lights provide brightness, making it easier to observe in dimly lit environments and facilitating operation.

[0029] The clamping plate 230 is clamped to the side wall of the track 100, which facilitates the clamping and fixing of the device to the track 100 through the clamping plate 230, making installation convenient.

[0030] An anti-slip pad is provided on the top of the inner cavity of the slot 210. The anti-slip pad is bonded to the top of the inner cavity of the slot 210. Specifically, the anti-slip pad helps to increase the friction of the support frame 200 and improve the anti-slip performance of the support frame 200 when it is engaged.

[0031] Mounting bracket 330 is a U-shaped bracket.

[0032] Combine Figure 1-Figure 4 The specific usage process of the track joint grinding device of this embodiment is as follows: During the grinding process of the track 100, the support frame 200 is snapped onto the track 100 through the slot 210. The first electric push rod 220 is used to push the clamping plate 230, so that the clamping plate 230 is clamped on both sides of the track 100, which facilitates fixing the grinding device on the track 100. According to the adjustment requirements of the grinding position, the first linear motor 300 and the second linear motor 310 are operated in coordination to drive the grinding disc 370 to move laterally and longitudinally, thereby adjusting the position of the grinding disc 370. The second electric push rod 320 is used to adjust the position of the grinding disc 370. The mounting bracket 330 is pushed to adjust the distance between the grinding disc 370 and the joint of the rail 100. The rotary motor 360 drives the rotating rod 350 to rotate, which in turn drives the grinding motor 340 to rotate. This makes it easy to adjust the grinding disc 370 to a horizontal or vertical position. The horizontal grinding disc 370 grinds the horizontal surface of the rail 100 joint, and the vertical grinding disc 370 grinds the vertical surface of the rail 100 joint. This allows for grinding operations on both the horizontal and vertical surfaces of the rail 100 joint, which helps to restore the optimal profile of the rail. It allows for faster and more accurate adjustments, has a high degree of intelligence, and improves grinding efficiency and quality.

[0033] Figure 4 The diagram shown is a structural schematic of a second embodiment of the track joint grinding device of this utility model. Please refer to [link / reference]. Figure 4 Unlike the above-described embodiments, the second linear motor 310 is equipped with blowers 400 on both its front and rear sides. The blower 400 has a metal shaping tube 410 at its air outlet, and a blower hood 420 is provided at one end of the metal shaping tube 410. Specifically, the blower 400 generates airflow to facilitate the cleaning of dust from the polished track 100. The metal shaping tube 410 allows for adjustment of the blowing angle and position of the blower hood 420 to meet the cleaning needs of different parts of the track 100. The blower hood 420 can increase the blowing area and improve the cleaning effect.
