[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0037] Example 1

[0038] Reference Figures 3-5 , which is the first embodiment of the utility model, provides a knocking component 106 of a vibration warning mechanism, which solves the problem of electromechanical vibration detection in coal mines, and includes a knocking component 106a on the knocking component 106 and a torsion spring 106b arranged on the outer surface of the knocking component 106a.

[0039] Specifically, the striking assembly 106 is provided with a ring 106a-1, a first transmission rod 106a-2 is connected to the outer surface of the ring 106a-1, a contact head 106a-3 is provided at one end of the first transmission rod 106a-2, a second transmission rod 106a-4 is connected to the outer surface of the ring 106a-1, and a firing pin 106a-5 is provided at the top of the second transmission rod 106a-4.

[0040] Furthermore, the contact head 106 a - 3 contacts the outer surface of the boss 104 .

[0041] The torsion spring 106b is installed on the outer surface of the ring 106a-1.

[0042] More preferably, the support assembly 105 is provided with a mounting platform 105a, a concentric column 105b extends from one end of the mounting platform 105a, a pull rod 105c extends from the outside of the column 105b, and a scale plate 105d is placed on the top of the pull rod 105c.

[0043] Among them, the knocking component 106 can be installed on the column 105b, and the knocking component is connected to the mounting platform 106a through the torsion spring 106b. The elasticity of the torsion spring 106b can drive the knocking component 106 to reset, so as to avoid the knocking component 106 and the supporting component 105 being too soft and rusty to affect the strength and sensitivity. Stainless steel is preferably used.

[0044] In summary, during use, when the boss 104 vibrates, the contact head 106a-3 moves, driving the first transmission rod 106a-2 and the second transmission rod 106a-4 to move together, so that the firing pin 106-5 at the top of the second transmission rod 106a-4 displays the vibration amplitude on the scale 105d, and through the torsion spring 106b installed on the outer surface of the ring 106a-1 and the outer surface of the mounting platform 105a, the contact head 106a-3 can follow the movement of the boss 104 in real time, thereby completing the real-time detection of the boss.

[0045] Example 2

[0046] Reference Figures 3-5 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a sound column 105e to solve the problem of being unable to warn maintenance personnel to repair coal mine electromechanical equipment.

[0047] Specifically, the sound column extends from the surface of the scale plate 105d.

[0048] Furthermore, the mechanical and electrical vibration of the coal mine will drive the firing pin 106a-5 to shake, thereby hitting the sound column 105d to make a sound.

[0049] The sound column is hollow and can easily make a sound due to collision with objects. The material is a material that can easily make a sound through collision, preferably stainless steel.

[0050] In summary, when the electromechanical equipment in the coal mine vibrates during use, it will drive the firing pin 106a-5 to hit the sound column 105e, making an obvious sound, thereby reminding the maintenance personnel to repair the electromechanical equipment in the coal mine and achieving the purpose of warning.

[0062] More preferably, the return spring 103 can be fixedly mounted on the movable rod assembly 102 and be concentric with the circular annular groove 102d.

[0063] The boss 104 is provided with a mounting groove 104 a and the return spring 103 can be mounted and fixed in the mounting groove 104 a.

[0064] In summary, when in use, first place the coal mine electromechanical on the chassis 201a, and drive the threaded rod 203a to move forward by rotating the handle 203b. The threaded rod 203a can push the base 203c to drive the clamping jaws 202c to clamp the coal mine motor, and then limit the second sliding rod 202a on the chassis wall 201b through the through hole provided on the chassis wall 201b. When the first sliding rod 102a is subjected to the vibration transmitted by the upper return spring 103 through the mounting ring groove 104a, it will push the piston 102b at one end of the first sliding rod 102a to squeeze the buffer liquid in the cavity 101b. The buffer liquid is squeezed outward through the first through holes 101d and 102c, and the remaining air in the cavity 101b is compressed, thereby realizing the effect of hydraulic buffering.
