[0029] In the embodiment: when the device is running, the coal mining machine is located above the bearing plate 1 to carry out the coal mining work, and in the process of gradually moving, the roller 2 may crush the impurities in the ore environment to cause the whole to be jolted, at this time, the side receiving the jolt will be lifted, at this time, the roller 2 will drive the buffer frame 4 to be lifted, at this time, the buffer wheel 8 will be in contact with the track 3 and push the stress plate 7 and the slide bar 5 to move, at this time, the slide bar 5 will slide with the buffer frame 4, and the spring 6 will also be compressed and buffer the kinetic energy, at this time, the buffer wheel 8 will offset the force generated by the jolt between the buffer wheel 8 and the track 3, thereby avoiding the phenomenon that the whole device is derailed, and when the buffering action is completed, the roller 2 will be in contact with the track 3 again to continue to carry the bearing plate 1 and the coal mining machine to carry out the coal mining work.

[0030] Further:

[0031] In an optional embodiment, the roller 2 and the buffer frame 4 are symmetrically arranged between the bearing plate 1 and the track 3.

[0032] In the embodiment: the roller 2 and the buffer frame 4 symmetrically arranged between the bearing plate 1 and the track 3 can enable the bearing plate 1 to stably run on the track 3, and under the action of the buffer frame 4, the whole device can also avoid the phenomenon of being derailed.

[0033] Further:

[0034] In an optional embodiment, the upper and lower sides of the track 3 are respectively provided with the roller 2 and the buffer wheel 8.

[0035] In the embodiment: the roller 2 and the buffer wheel 8 arranged on the upper and lower sides of the track 3 can drive the buffer wheel 8 to be in contact with the track 3 and achieve buffering when the bearing plate 1 is jolted, can keep a stable clamping state with the roller 2 between the track 3, and provide a stable basis for subsequent buffering action, and can avoid the phenomenon that the whole device is derailed.

[0036] Further:

[0037] In an optional embodiment, the buffer frame 4 is shaped like an "I" shape.

[0038] In this embodiment, the "I"-shaped geometry enables a stable connection between it and the support plate 1, while also ensuring that the bottom of the slide bar 5 can slide with the buffer frame 4.

[0039] Furthermore:

[0040] In an optional embodiment, the slide bars 5 are arranged parallel to each other on the surface of the force plate 7, and the surface of the buffer frame 4 is also provided with through holes that match the slide bars 5.

[0041] In this embodiment, the parallel sliding rods 5 can effectively slide between the sliding rods 5 and the buffer frame 4 when the buffer wheel 8 and the track 3 come into contact, and then provide a stable buffering effect through the contraction of the spring 6.

[0044] In this embodiment, the force plate 7 and buffer wheel 8 set between the track 3 and the buffer frame 4 can protect them through the track 3 and the buffer frame 4, avoiding the impact of environmental factors such as ore on their buffering state.

[0045] The working principle and usage process of this utility model are as follows: When the device is running, the coal mining machine is located on the bearing plate 1 to carry out coal mining work. During the gradual movement, the roller 2 may crush impurities such as ore in the environment, causing the whole device to shake. At this time, the side affected by the shaking will lift up. The roller 2 will drive the buffer frame 4 to lift up. At this time, the buffer wheel 8 will come into contact with the track 3 and push the force plate 7 and the slide rod 5 to move. At this time, the slide rod 5 will slide with the buffer frame 4. At the same time, the spring 6 will be compressed and buffer the kinetic energy. At this time, the buffer wheel 8 and the track 3 will cancel out the force generated by the shaking, thereby preventing the whole device from derailing. After the buffering effect is completed, the roller 2 will re-make contact with the track 3 and continue to support the bearing plate 1 and the coal mining machine to carry out coal mining work.

[0046] Finally, it should be noted that: the above is only the preferred embodiment of the utility model, and is not used to limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or make equivalent replacement to part of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
