For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0035] In view of the shortcomings of the existing technology, this embodiment provides a track reversible car blocker, which can be specifically described as follows:

[0036] As attached Figure 1 and attached Figure 2 As shown, a track-reversible car arrester includes an outer frame 1, a rotating plate 2 and a rotating rod 3. A accommodating groove 11 is provided inside the outer frame 1, and the outer frame 1 is arranged at the bottom of the mine track and is detachably connected to the mine track to facilitate the disassembly of the car arrester for maintenance or replacement; a rotating plate 2 is provided inside the accommodating groove 11, and a counterweight block 21 is provided on one side of the rotating plate 2. Through the action of the counterweight block 21, one end of the rotating plate 2 can be pressed down and the other end can be tilted. The tilted end of the rotating plate 2 protrudes from the surface of the mine track to facilitate cooperation with the mine car and prevent the mine car from slipping; a rotating rod 3 is provided at the bottom of the rotating plate 2, and the rotating rod 3 is rotatably cooperated with the outer frame 1, and the rotating rod 3 is located on the outside of the mine track to facilitate manual driving of the rotating rod 3 to rotate, thereby driving the rotating plate 2 to flip, so that the mine car passes through the car arrester.

[0037] In the initial state, the counterweight 21 is located at one end of the rotating plate 2, and under the action of the counterweight 21, the rotating plate 2 rotates to one end, and the other end of the rotating plate 2 protrudes from the outer frame 1 and the surface of the mine track, and a mine car is slidingly set on the mine track, and the raised end of the rotating plate 2 abuts against the mine car to block the mine car from passing through; and the rotating plate 2 is provided with one end of the counterweight 21 facing the direction of entering the well, and the raised end of the rotating plate 2 facing the direction of exiting the well, that is, when the mine car enters the mine, it will be intercepted by the car blocker, and when the mine car exits the well, it will squeeze the surface of the rotating plate 2 and make the rotating plate 2 rotate, so that it can smoothly pass through the car blocker, and the rotating plate 2 will return to its initial state under the action of the counterweight 21.

[0038] In this embodiment, the rotating rod 3 includes a rotating shaft rod and a driving rod. The rotating shaft rod is arranged at the bottom of the rotating plate 2, and the rotating shaft rod is rotatably matched with the outer frame 1 so that the rotating plate 2 can be rotatably set in the accommodating groove 11; one end of the rotating shaft rod passes through the outer frame 1 and protrudes from the outer surface of the outer frame 1. The driving rod is connected to the rotating shaft rod, and the two are arranged vertically. The driving rod and the surface of the rotating plate 2 form a certain angle, so that when the rotating plate 2 flips, the driving rod and the surface of the outer frame 1 form a small angle, which is convenient for manual hand-holding of the rotating rod 3 to rotate, thereby allowing the mine car to pass.

[0039] Furthermore, the driving rod can be located at one end of the rotating plate 2 where the counterweight 21 is set, so that the driving rod can also provide a certain counterweight effect, which facilitates the lifting of one end of the rotating plate 2; it also facilitates the resetting of the rotating plate 2 after rotation; the driving rod can also be located at the end of the rotating plate 2 away from the counterweight 21. When the driving rod is located at this end, the weight of the driving rod is much less than the weight of the counterweight 21.

[0040] Furthermore, the driving rod can also be a pedal rod; when the driving rod is in the pedal rod position, the driving rod is located at the end of the rotating plate 2 away from the counterweight block 21. When the rotating plate 2 is in the initial state, the driving rod is tilted at a large angle to facilitate manual stepping, so that the rotating plate 2 rotates and the mine car passes.

[0041] In this application, an embodiment is shown in the attached Figure 2 As shown, a bent edge 22 is provided on the side of the rotating plate 2 away from the counterweight 21, and the bent edge 22 is arranged perpendicular to the surface of the rotating plate 2; and the bent edge 22 is located at the raised end of the rotating plate 2, and the bent edge 22 abuts against the mine car. When the mine car moves to the position of the outer frame 1 on the mine track, the bottom of the mine car abuts against the bent edge 22. Through the bending arrangement of the bent edge 22, not only can the contact area with the mine car be increased, and the mine car can be effectively abutted against the mine car to prevent the movement of the mine car, but also a certain shock absorption can be performed through its bending effect, thereby preventing the moving force of the mine car from directly acting on the rotating plate 2 as a whole, causing bending damage to the rotating plate 2, etc.

[0042] In one embodiment of the present application, the rotating rod 3 is located on one side of the center of the rotating plate 2, that is, the rotating plate 2 is located at a position near one end of the bottom of the rotating plate 2, deviating from the center of the rotating plate 2, so that the distance that one end of the rotating plate 2 drops is smaller, and the distance that the other end of the rotating plate 2 rises is larger, so as to facilitate one end of the rotating plate 2 to protrude from the surface of the mine track.

[0043] As attached Figure 2 and attached Figure 3 As shown, a track-reversible car arrester also includes a first limit component 4 and a second limit component 5. The first limit component 4 and the second limit component 5 are both arranged in the accommodating groove 11. The first limit component 4 cooperates with the counterweight block 21 to limit the angle of rotation of the counterweight block 21 in the direction away from the mine track, to prevent the counterweight block 21 from touching the bottom, causing the counterweight block 21 to flip over at a large angle and unable to reset, and also to avoid damage to the counterweight block 21; the second limit is not arranged on the side of the accommodating groove 11 away from the first limit component 4, that is, the first limit component 4 and the second limit component 5 are respectively located on both sides of the inside of the accommodating groove 11, and the second limit component 5 cooperates with the rotating plate 2 to limit the angle of rotation of the rotating plate 2 in the direction away from the mine car.

[0044] In this embodiment, as shown in the attached Figure 3 As shown, the first limiting component 4 includes a first baffle 41 and a first buffer component 42. The first baffle 41 is arranged in the receiving groove 11 and is located at the bottom of the counterweight 21. The first baffle 41 cooperates with the counterweight 21 to prevent the counterweight 21 from rotating. When the rotating plate 2 rotates under the action of the counterweight 21, the counterweight 21 will abut against the first baffle 41. The first buffer component 42 is also provided on the first baffle 41. The first buffer component 42 cooperates with the counterweight 21. When the counterweight 21 During rotation, the counterweight 21 rests against the first buffer assembly 42 and buffers the rotation of the counterweight 21, which can effectively prevent the first baffle 41 from colliding with the counterweight 21 and causing damage to both. Furthermore, when the mine car supports the rotating plate 2, it will also have a certain impact force on the rotating plate 2, and the impact force will act on the counterweight 21. The counterweight 21 rotates rapidly and hits the first baffle 41. The first buffer assembly 42 is provided on the first baffle 41, which can also effectively buffer the supporting force of the mine car.

[0045] In this embodiment, the first buffer assembly 42 is a buffer spring or an oil pressure buffer.

[0046] In this embodiment, a chamfer 23 is provided on one side of the counterweight block 21, and the chamfer 23 cooperates with the first buffer assembly 42 when rotating; specifically, when the rotating plate 2 is in an inclined state, the counterweight block 21 is also in an inclined state, and the chamfer 23 is in a horizontal state, so as to facilitate the support and cooperation with the first buffer assembly 42.

[0047] In this embodiment, as shown in the attached Figure 3 As shown, the second limiting assembly 5 includes a second baffle 51 and a second buffer assembly 52. ​​The second baffle 51 is arranged in the accommodating groove 11 and is located at the bottom of the rotating plate 2. The second baffle 51 cooperates with the rotating plate 2 to limit the rotating plate 2 from rotating in the direction away from the mine car; a second buffer assembly 52 is provided on the top of the second baffle 51, and the second buffer assembly 52 cooperates with the bottom wall of the rotating plate 2. When the rotating plate 2 rotates under the action of external force, the rotating plate 2 can abut against the second buffer assembly 52 for buffering, and the rotation angle of the rotating plate 2 is limited by the second baffle 51.

[0048] Specifically, the top wall of the second buffer assembly 52 is lower than the upper surface of the mine track or the outer frame 1 , so as to facilitate the complete retraction of the tilted end of the rotating plate 2 into the accommodating groove 11 .

[0049] In this embodiment, the second buffer assembly 52 is a buffer spring or an oil pressure buffer; the first buffer assembly 42 and the second buffer assembly 52 are not limited to the above components, and can also be other components with a buffering function.

[0050] In this embodiment, fixing grooves 6 are respectively provided on both sides of the outer frame 1, and a plurality of through holes 61 are provided on the top of the fixing grooves 6. Fixing members are provided inside the through holes 61, and the fixing members cooperate with the mine track, so that the outer frame 1 and the mine track are detachably connected; specifically, the fixing members are bolts, and threaded holes are provided at the bottom of the mine track. The bolts cooperate with the threaded holes, so that the outer frame 1 and the mine track are detachably connected, which is also convenient for subsequent disassembly, replacement and maintenance.

[0051] Those skilled in the art will readily conceive of other embodiments of the present invention after considering the specification and practicing the embodiments disclosed herein. This invention is intended to cover any variations, uses, or adaptations of the invention that adhere to the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein.
