[0014] The utility model is described in detail below with reference to the accompanying drawings:
[0015] like Figure 1 and 2 As shown, an anti-runaway device for an inclined shaft comprises a bracket 1, which is in a gate-shaped structure. A fixing piece 2 is respectively provided at the upper and lower ends of the bracket 1, and the bracket can be fixed in the mine tunnel by the fixing piece 2. Specifically, the fixing piece 2 comprises a plurality of sleeves 201. In this embodiment, two sleeves 201 are provided and are located at the two ends in the width direction of the bracket 1. An anchor rod 202 is provided in the sleeve 201, and the anchor rod 202 can be inserted into the tunnel to install and fix the bracket 1. A plurality of sleeves 3 are provided on the top of the bracket 1. In this embodiment, five sleeves 3 are provided. The sleeves 3 are arranged along the width direction of the bracket 1 and the sleeves 3 are horizontally arranged. The sleeves 3 face the length direction of the tunnel. A pull rod 4 is provided in the sleeve 3, and the pull rod 4 can move in the sleeve 3 along the length direction of the sleeve 3. A limit baffle 5 is provided at one end of the pull rod 4, and a steel wire rope 6 is connected to the other end. The steel wire rope 6 can be used to The mine car is blocked to prevent it from running away. A spring 7 is sleeved on the pull rod 4, one end of the spring 7 is set on the limit baffle 5, and the other end is fixed on the sleeve 3. The wire rope 6 can pull the pull rod 4 to move and compress the spring 7, and the spring 7 is used for buffering. The bottom of the bracket 1 is detachably installed with a connecting rod 8, and the connecting rod 8 is arranged along the width direction of the bracket. Specifically, an inverted J-shaped lower hook 9 is provided at each end of the bottom width direction of the bracket 1, and the two ends of the connecting rod 8 are respectively located in the two lower hooks 9. The connecting rod 8 is installed through the lower hooks 9, and the end of the wire rope 6 away from the pull rod 4 is fixed on the connecting rod 8. After the connecting rod 8 is installed on the lower hook 9, the wire rope 6 can be straightened and all the wire ropes 6 are parallel to each other after straightening. The mine car can be blocked by multiple wire ropes 6 to prevent it from sliding down and running away.
[0016] A J-shaped upper hook 10 is provided at each end of the middle width direction of the bracket 1. When the mine car needs to pass through the bracket 1, the two ends of the connecting rod 8 can be placed on the upper hook 10, and the lower part of the wire rope 6 can be lifted to leave moving space for the mine car to move and pass through the bracket 1.
[0017] The usage of the utility model is as follows:
[0018] First, insert the anchor rod 202 on the fixing member 2 into the corresponding position in the mine tunnel, and then install the connecting rod 8 on the lower hook 9. When the mine car in the tunnel slides down and runs away, when the mine car moves to the bracket 1, the mine car hits the wire rope 6, and the wire rope 6 prevents the mine car from continuing to move downward under the action of gravity. Specifically, when the wire rope 6 is hit by the mine car, the wire rope 6 is bent by the force and pulls the pull rod 4 in the sleeve 3 to move away from the end of the limit baffle 5. At this time, the spring 7 can buffer the limit baffle 5 and the pull rod 4, and transfer the tension to the wire rope 6, so that the wire rope 6 buffers the mine car, so that the wire rope 6 can buffer the mine car when it is hit by the mine car, ensure that the mine car is prevented from moving, and prevent damage to the mine car. In addition, since the contact area between the wire rope 6 and the end of the mine car is large, the mine car is evenly stressed, which can prevent the mine car from flipping over and derailing from the track.
