[0002] Rail weld grinding can be basically divided into three areas: rail head, rail waist and rail bottom. Domestic seamless rail weld grinding equipment is mainly focused on the grinding of rail heads. However, for seamless rails with strict construction requirements, the rail bottom also needs to be polished. Moreover, rail bottom grinding is the area that takes the longest time, has the greatest labor intensity, and has the most prominent safety risks. At present, there is no special equipment for rail bottom grinding. It mainly relies on manual track lifting and handheld grinding. During the grinding process, the operator needs to get close to the grinding work surface and observe the grinding effect at all times, which brings many risks, such as: object impact risk, splash scratch risk, occupational stress risk caused by particulate matter, etc. In addition, it is very difficult to control the grinding amount during manual grinding, and it is often the case that excessive grinding damages the parent material or insufficient grinding occurs. In addition, due to the misalignment of the rail joint and the size deviation of the rail itself, the ground of the rails at both ends after welding is not in the same plane. Mechanical grinding cannot identify and judge the grinding amount, which is also the key constraint factor that many grinders cannot be put into practical use. Summary of the invention

For example, in this embodiment, four groups of the pressing plates, elastic members, connecting members and hooks are provided, which are distributed on the inner sides of the four corners of the fixed plate.

[0030] In one embodiment, the connecting member includes a fixed sleeve, a connecting rod is provided in the fixed sleeve, the upper end of the connecting rod is connected to the pressure plate, and the lower end of the connecting rod is rotatably connected to the hook via a rotating shaft.

[0031] In a preferred embodiment, the roller is provided on the lower side of the right end of the fixed plate, and the lower side of the left end of the fixed plate is also rotatably connected to a fixed frame, for example, a fixed rod is connected to the lower side of the left end of the fixed plate, the fixed frame cooperates with the fixed rod and can rotate, and a compression spring is provided between the fixed rod and the fixed frame so that the fixed frame can receive a force directed to the rail, and the fixed frame is provided with a rail waist fixing wheel facing the rail, so that the rail waist fixing wheel can be held against the rail waist of the rail.

[0034] Example 1

[0035] In this embodiment, the grinding group structure is mainly composed of a hanging rod, a support body, a guide wheel, a driving motor, a handle, a screw, a fixing seat, a grinding head, a stopper, etc. The grinding group structure ensures that the guide wheel and the grinding head are in a relatively horizontal state through the support body and the baffle, and the relative position can be adjusted by the handle to achieve the purpose of fine-tuning the grinding amount.

The roller structure mainly plays a guiding and positioning role during the pushing process to ensure that the rail bottom grinding device does not deflect when running along the rail. The tension spring is placed in the fixed sleeve and connected to the pressure plate. When the pressure plate is manually pressed, the pull rod drives the hook to move down, and the hook directly hooks the hanging rod.
