[0002] Coal mine tunnel transportation tracks are important infrastructure for transporting coal, materials and personnel in coal mining. The tracks laid in the tunnels are used to carry transportation vehicles. When the tracks are laid in coal mine tunnels in earthquake-prone areas, in order to ensure the stability and safety of the transportation system, it is usually necessary to take certain measures to dampen the tracks. In the prior art, shock absorbers or shock pads are usually used to dampen the tracks. However, since shock absorbers and shock pads are mainly used to dampen the vibrations up and down the tracks, their buffering and adaptability to the lateral displacement of the tracks and the thermal expansion and contraction caused by temperature changes are relatively limited. When the tracks are laid in the tunnels, the two sections of tracks are spliced ​​together by welding or bolts. In the event of an earthquake, stress concentration, loosening or even breakage may occur at the joints, thereby affecting the stability and safety of the tracks.

[0003] Therefore, a transport track with earthquake wave detection, absorption and buffering functions has been developed, which can cushion and reduce shock on the track and make the track retractable, so as to improve the flexibility in dealing with ground vibrations, enhance the stability and safety of the track, and extend the life of the track.

[0034] The present invention is further described below in conjunction with specific embodiments.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] A transport track with earthquake wave detection, absorption and buffering functions, such as Figure 1 and Figure 2 As shown, it includes a mounting frame 1, a track 2, a fixing member 3, a buffer mechanism 4 and a docking mechanism 5. Eight fixing members 3 are detachably connected to the upper side of the mounting frame 1 by bolts. The track 2 is clamped between the four front fixing members 3, and the track 2 is also clamped between the four rear fixing members 3. The mounting frame 1 is provided with a buffer mechanism 4, and the track 2 is provided with a docking mechanism 5.

[0036] like Figure 1 , Figure 3 and Figure 4As shown, the buffer mechanism 4 includes a shock absorbing plate 41, a fixed seat 42, a first connecting frame 43, a damper 44, a second connecting frame 45 and a seismic isolation support 46. The shock absorbing plate 41 is located at the lower side of the mounting frame 1. The front and rear sides of the shock absorbing plate 41 are connected to two left and right fixed seats 42. The fixed seats 42 are provided with mounting holes for easy installation. Sixteen first connecting frames 43 are connected to the upper side of the shock absorbing plate 41. The first connecting frames 43 are rotatably connected to the dampers 44. The upper parts of the dampers 44 are rotatably connected to the second connecting frames 45. Seismic isolation supports 46 are connected between two adjacent second connecting frames 45. The lower sides of the seismic isolation supports 46 are connected to the shock absorbing plate 41, and the upper sides of the seismic isolation supports 46 are connected to the mounting frame 1.

[0037] like Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, the docking mechanism 5 includes a fixed plate 51, a first connecting member 52, a second connecting member 53, a first telescopic rod 54 and a first spring 55. The left and right parts of the track 2 are connected to the front and rear fixed plates 51, the first connecting member 52 is connected between the two adjacent fixed plates 51, the first connecting member 53 is slidably connected to the first connecting member 52, the front and rear sides of the second connecting member 53 are also connected to the fixed plate 51, the first connecting member 53 is connected to the first connecting member 52 connected thereto, and the first spring 55 is connected between the first connecting member 52 and the first telescopic rod 54 connected thereto.

[0038] When using the present invention, the shock-absorbing plate 41 is first installed in the track 2 laying area through the fixing seat 42, and then the track 2 is installed on the mounting frame 1 through the fixing member 3, and the track 2 is connected to the first connecting member 52 and the second connecting member 53 through the fixing plate 51. When the transport vehicle moves on the track 2 or an earthquake occurs on the ground, the track 2 vibrates, and the mounting frame 1 vibrates accordingly, the second connecting frame 45 and the first connecting frame 43 move, and the damper 44 retracts and rotates to reduce the vibration of the second connecting frame 45 and the first connecting frame 43. The shock-absorbing plate 41 and the seismic isolation support 46 dampen the mounting frame 1. When the track 2 is laterally displaced due to the earthquake, the second connecting member 53 moves on the first connecting member 52, and the first telescopic rod 54 and the first spring 55 shrink and then rebound, thereby playing a role in buffering and damping the track 2, and enabling the track 2 to be retracted, so as to improve the flexibility in dealing with ground vibrations, enhance the stability and safety of the track 2, and extend the service life of the track 2.

[0039] like Figure 1 , Figure 8 and 9As shown, it also includes a support mechanism 6, which includes a support frame 61, a second telescopic rod 62, a top plate 63, a second spring 64, a swing rod 65, a guide frame 66 and a force block 67. The upper sides of the left and right parts of the shock-absorbing plate 41 are connected to the support frame 61, the front and rear parts of the support frame 61 are connected to the second telescopic rod 62, the top plate 63 is connected between the telescopic ends of two adjacent second telescopic rods 62, the second spring 64 is connected between the second telescopic rod 62 and the connected top plate 63, the swing rod 65 is rotatably connected to the lower middle part of the top plate 63, four guide frames 66 are connected to the upper middle part of the shock-absorbing plate 41, and the force block 67 is slidably connected between two adjacent guide frames 66, and the force block 67 is rotatably connected to the adjacent swing rod 65.

[0040] The support mechanism 6 of the device can be used to support the mounting frame 1. After the transport vehicle moves to above the top plate 63, the top plate 63 is squeezed to move downward, and the second telescopic rod 62 and the second spring 64 are contracted. While the top plate 63 moves downward, the swing rod 65 is driven to move downward, so that the swing rod 65 pushes the force block 67 to move on the guide frame 66, so that the force block 67 moves to the lower side of the mounting frame 1, thereby supporting the mounting frame 1 and improving the stability of the mounting frame 1.

[0041] like Figure 1 , Fig.10 and Fig.11 As shown, an adjustment mechanism 7 is also included, and the adjustment mechanism 7 includes a support plate 71, an adjustment screw rod 72 and a baffle plate 74. The support plate 71 is connected to the lower side of the first connecting member 52, and the support plate 71 is rotatably connected to the adjustment screw rod 72. The adjustment screw rod 72 is provided with a knob for easy rotation adjustment. The adjustment screw rod 72 is threadedly connected to the adjustment plate 73, and the adjustment plate 73 is slidably connected to the adjacent support plate 71. The baffle plate 74 is connected to the lower side of the second connecting member 53.

[0042] By using the adjustment mechanism 7 of the device, the moving range of the second connecting member 53 can be adjusted. According to the earthquake conditions in the coal mine tunnel, the adjusting screw 72 is rotated to move the adjusting plate 73 along the supporting plate 71, and the distance between the baffle 74 and the adjusting plate 73 is adjusted. The adjusting plate 73 limits the baffle 74, and then limits the second connecting member 53, thereby playing a role in adjusting the moving range of the second connecting member 53 to facilitate adaptation to earthquake conditions in different regions.

[0043] like Figure 1 and Fig.12As shown, an anti-deflection mechanism 8 is also included, and the anti-deflection mechanism 8 includes a support block 81, a third telescopic rod 82, a third spring 83 and a locking piece 84. The upper sides of the front and rear parts of the shock-absorbing plate 41 are connected to the left and right support blocks 81, and the support blocks 81 are connected to the third telescopic rod 82. The telescopic ends of the third telescopic rod 82 are connected to the locking pieces 84. The third springs 83 are connected between the locking pieces 84 and the connected third telescopic rod 82, and the locking pieces 84 are engaged with the adjacent first connecting piece 52.

[0044] The anti-deflection mechanism 8 of the device can prevent the track 2 from deviating. Through the force of the third spring 83, the locking member 84 on the third telescopic rod 82 is always engaged with the first connecting member 52 to limit the first connecting member 52, thereby preventing the track 2 from deviating and improving the safety of the transport vehicle.

[0045] like Figure 1 and Fig.13 As shown, an alarm mechanism 9 is also included, which includes an alarm 91, an alarm light 92 and a touch switch 93.

The touch switches 93 are connected to the alarm 91 through wires. The touch switches 93 are located on the upper side of the shock-absorbing plate 41.

[0046] By using the alarm mechanism 9 of the present device, an alarm reminder can be issued when the mounting frame 1 vibrates with a large amplitude. When the mounting frame 1 vibrates with a large amplitude, the touch switch 93 is driven to move. When the touch switch 93 touches the shock absorbing plate 41, the touch switch 93 is activated, causing the alarm 91 to sound an alarm and the alarm light 92 on the alarm 91 to light up, thereby playing the role of issuing an alarm reminder when the mounting frame 1 vibrates with a large amplitude, so as to remind the staff to evacuate in time.
