[0016] The utility model will be further described in detail in combination with the drawings.
[0017] As Figure 1 The utility model discloses a main part of mine cage lifting mine car car stopper linkage device including car stopper 1, side resistance 2, pull rod 3, side resistance shaft 4, mine car baffle 5, mine car carriage 6, mine car 7, cage wall 8, linkage steel rope 9, first guide wheel 10 and second guide wheel 11.
[0018] For the convenience of the main improvement point of the utility model, give a traditional cage mine car car stopper structural schematic diagram, and specifically as Figure 2 From Figure 1 And Figure 2 The main improvement of the utility model can be seen by using linkage steel rope 9, first guide wheel 10, second guide wheel 11 to realize. The specific components and connection relationship are as follows:
[0019] The side block 2 and the lever 3 are arranged on the side block shaft 4, and the side block 2 and the lever 3 are fixedly connected with the side block shaft 4 and can make a circular motion with the side block shaft 4. The side block shaft 4 is arranged on the cage wall 8, and the side block shaft 4 is movably connected with the cage wall 8, so that the lever 3 can be pulled.
[0020] One end of the linkage steel rope 9 is connected with the lever 3, and the other end of the linkage steel rope 9 is connected to the blocking end of the car retarder 1. In the embodiment, the linkage steel rope 9 is connected with the car retarder by penetrating through the steel rope fixing hole of the car retarder 1 and being bound. The linkage steel rope 9 is guided by the first guide wheel 10 and the second guide wheel 11 to change from the vertical direction to the horizontal direction and then to the vertical direction again. Specifically, the first guide wheel 10 is arranged on the cage ground directly below the lever 3, the second guide wheel 11 is arranged on the cage ground directly below the steel rope fixing hole of the car retarder, and the first guide wheel 10 and the second guide wheel 11 are fixedly connected with the cage ground through bearings.
[0021] The middle part of the car retarder 1 is fixedly connected with the cage ground through a movable shaft, and the car retarder 1 takes the movable shaft as a fulcrum and can move up and down at both ends, so that the car retarder 1 as a whole is like a lever. The counterweight end of the car retarder 1 needs to be counterweighted, so that when the linkage steel rope 9 does not pull the blocking end of the car retarder, the blocking end is at the highest position, and the car retarder is kept in the blocking state.
[0022] As Figure 1 When the mine car enters the cage, the operator manually pulls the lever 3 on the side block shaft 4 to the position perpendicular to the cage wall 8, and the side block 2 fixed on the side block shaft 4 reaches the same position at the same time, and the side block 2 keeps the mine car body 6 in the blocking state; at the same time, the counterweight end of the car retarder 1 falls under the slack state of the linkage steel rope 9, and the blocking end is lifted, keeping the mine car baffle 5 in the blocking state, so that the car retarder 1 and the side block 2 are kept in the blocking state at the same time.
[0023] As Figure 4 When the mine car 7 needs to be pushed out of the cage, the car pusher lifts the lever 3, and the side block 2 and the cage wall 8 are in a parallel position, at which time the side block 2 and the mine car body 6 are in a disengaged state. Because the linkage steel rope 9 is in a tensioned state, the car retarder 1 and the mine car baffle 5 are in a disengaged state through the guidance of the first guide wheel and the second guide wheel and the pulling force, so that the car retarder 1 and the side block 2 are kept in the running state at the same time.
[0024] The linkage steel rope 9 can also be replaced by a connecting rod + lever. An example using a connecting rod + lever is given below. One end of the lever 3 is hinged to the connecting rod, and the other end of the connecting rod is hinged to one end of the lever. The fulcrum of the lever is set on the cage floor, and the other end of the lever is hinged to the blocking end of the car stopper 1. When the lever 3 is down and perpendicular to the cage wall, the side stopper 2 is in the blocking state of the mine car. The connecting rod pushes down one end of the lever connected to it, and the other end of the lever is raised, causing the blocking end of the car stopper 1 to tilt up, and the car stopper 1 is in the blocking state. Conversely, the car stopper 1 is unlocked, and the mine car 7 can be pushed out of the cage. When the linkage steel rope 9 can also be replaced by a connecting rod + lever, because this linkage mechanism has two 90° angles... 0 For cornering, the linkage and lever system is a rigid structure with a relatively complex connection method, which has the following disadvantages:
[0025] 1. The rotation angle and circumference of the lever (the movement of the fixed point around the edge resistance axis) must be completely consistent with the rotation angle and circumference of the lever, requiring high precision.
[0026] 2. When using lever connections, the diameter of the lever's circular motion is required to be relatively large, which affects the entry and exit of the mine car.
[0027] 3. The lever and connecting rod are connected by a screw, which increases the failure rate.
[0028] Both the front and rear of the mine car 7 should be equipped with a car stopper 1, a side stopper 2, and a lever 3. The side stops 2 and lever 3 at both ends of the mine car 7 are connected to the same side stopper shaft 4, ensuring that when the lever 3 is raised, both the front and rear side stops 2 are in the unlocked state; when the lever 3 is pressed down, both the front and rear side stops 2 are in the driving state. The connection method between the front car stopper 1 and the front side stopper 2 of the mine car 7 is the same as that between the rear car stopper 1 and the rear side stopper 2 of the mine car 7.
