[0032] Here’s how it works:

[0033] When the flexible mine car protection device is to be used, the frame 1 can be installed inside the mine roadway, and the energy absorber 8 can be combined and docked with the ground. In this way, the rapid assembly and use of the flexible mine car protection device can be realized. During the use process, the mine car can move along the track. When there is no need for blocking and protection activities, the winding and unwinding winch 2 provided at the rear side of the upper end of the frame 1 can be automatically driven before the mine car moves into the frame 1, so that the winding and unwinding winch 2 winds the cables 3 connected to both outer ends. The two cables 3 can cooperate with the pulleys 4 connected to the outside to realize the lifting of the bottom docking protection pipe rack 5, so that the protection pipe rack 5 does not block the moving and transporting track of the mine car. If blocking and protection activities are required, the winding and unwinding winch 2 can be driven again, so that the winding and unwinding winch 2 cooperates with the pulley 4 to lead out the cable 3. In this way, the protection pipe rack 5 in the open state can be adjusted to the closed blocking state to block the moving track of the mine car. Thus, when the mine car is out of control, it will be blocked by the protection pipe rack 5 to realize the blocking and protection cooperation. Secondly, when the protection pipe rack 5 is impacted, the pulling of the three internally connected steel wires 7 inside will be realized, so that the steel wires 7 provide a certain resistance, and with the cooperation of the energy absorber 8 connected to the rear ends of the three steel wires 7, the absorption of the impact force is realized, further improving the blocking and protection effect of the mine car and ensuring the safety of the mine car during the use process;

[0034] To ensure the real-time monitoring of the position of the mine car, a protection monitoring device 9 is also provided in the middle of the rear side of the upper end of the frame 1. In this way, the efficient monitoring and dust protection cooperation can be realized, ensuring that the sensor main body 93 realizes stable position monitoring as a whole, and making the switch state of the flexible mine car protection device stable. The sensor main body 93 can be inserted into the protection box 92 and cooperate with the clamping assembly 94 provided at the front side of the upper end of the protection box 92 to realize rapid installation, reducing too many cumbersome installation steps. In this way, under the protection cooperation of the protection box 92, the sensor main body 93 can be in a stable monitoring state, avoiding the appearance of external dust adhesion. Secondly, a transparent dust-proof plate 96 is also provided at the bottom of the protection box 92 to ensure that the monitoring process of the sensor main body 93 is not blocked and still can maintain an efficient monitoring state;

[0035] When subsequent disassembly and maintenance activities of the sensor main body 93 are required, the handle 942 provided on the front side of the clamping block 941 can be pushed to cause the counterclockwise rotation of the rotating bar 943 provided inside the clamping block 941. With the counterclockwise rotation of the rotating bar 943, the connecting bars 944 rotatably connected to the left and right sides of the rotating bar 943 will pull the docking plug shaft 945 at the outer end correspondingly. In this way, the plug shafts 945 inserted correspondingly inside the clamping block 941 on both sides will be laterally moved into the clamping block 941 to complete the unlocking activity. Thus, the clamping block 941 can be removed from the front side of the upper end of the protective box 92 to release the clamping lock of the sensor main body 93, enabling the convenient disassembly and maintenance of the sensor main body 93. When reinstalling and clamping the sensor main body 93 later, the handle 942 needs to be pushed again to make the plug shafts 945 on both sides perform a pre-lateral movement and retraction activity in cooperation with the guide rods 946 connected up and down on the inner side. During the retraction process, the compression spring 947 provided on the outer side of the guide rod 946 will be compressed. Thus, after the clamping block 941 is positioned and docked with the protective box 92 in cooperation with the clamping blocks 948 provided on the left and right sides of the outer end, the handle 942 can be released to make the compressed compression spring 947 rebound to push out the plug shaft 945. In this way, the plug shafts 945 on both sides can be automatically inserted into the clamping block 941 to achieve automatic plugging and locking. Furthermore, with the clamping block 941 and the protective box 92 cooperating again, the convenient installation and use of the sensor main body 93 can be realized again, thus achieving the advantages of convenient disassembly and assembly cooperation of the sensor main body 93 and ensuring the convenience of use;

[0036] Secondly, to improve the functional use of the protection and monitoring device 9, an adjustment component 97 is also provided on the left side of the connection frame 91 to manually adjust the monitoring angle of the sensor main body 93 to meet the monitoring use requirements of different mine tunnels. That is, when the monitoring angle needs to be adjusted, the pressing plate 972 rotatably connected to the upper end of the connection shell 971 can be squeezed to cause the right side of the pressing plate 972 to rise accordingly, so as to release the docking lock with the trapezoidal groove between the adjacent serrated blocks 975 on the outer side of the rotating cylinder 974. At the same time, when squeezing the pressing plate 972, the spring 973 provided at the bottom on the left side will be compressed. After the unlocking activity of the pressing plate 972 and the rotating cylinder 974 is completed, the whole protective box 92 can be pushed to make the protective box 92 rotate along the inside of the connection frame 91 in cooperation with the rotating shafts 95 provided on the left and right sides of the outer end to achieve flexible angle adjustment. After adjusting to the appropriate angle, the pressing plate 972 can be released to make the spring 973 rebound and push up. Thus, the docking end on the right side of the pressing plate 972 can be clamped into the groove between a new pair of adjacent serrated blocks 975 to achieve convenient adjustment and locking, ensuring that the protective box 92 can be in a stable protection state after the angle adjustment. Secondly, with the accurate docking activity of the docking groove 976 and the docking block 977 provided inside the rotating cylinder 974, the adjustment component 97 and the left rotating shaft 95 can achieve accurate and firm docking and transmission cooperation, thus achieving the advantage of flexible manual adjustment and cooperation of the monitoring angle of the sensor main body 93.

[0037] The present utility model provides a flexible sports car protection device. By providing a protection monitoring device 9, that is, under the protection cooperation of the protection box 92, the clamping component 94 and the dust-proof plate 96, the sensor main body 93 can be in a stable dust-proof protection state, reducing dust adhesion and affecting the monitoring efficiency. Moreover, in cooperation with the clamping component 94, through the transmission of the rotating bar 943 and the connecting bar 944, the inserted shafts 945 provided on both sides can be conveniently pushed and pulled, so that the sensor main body 93 can be conveniently taken out from the inside of the protection box 92 for maintenance, thus achieving the advantages of dust-proof position monitoring cooperation and convenient maintenance and use. In addition, the sensor main body 93 is provided. That is, by pressing the pressing plate 972, the combined clamping with the serrated blocks 975 provided at equal distances on the outer side of the rotating cylinder 974 can be quickly released, enabling the rotating cylinder 974 to rotate and conveniently adjusting the use angle of the sensor main body 93, thus achieving the advantage of flexible manual adjustment of the monitoring angle of the sensor main body 93.
