Description
Technical Field
[0001] This utility model relates to the field of transportation safety technology, specifically a novel hydraulic vehicle stop device for inclined shafts. Background Technology
[0002] A runaway vehicle stopper, also known as a parking device, is an important facility in the coal mine transportation system. It is a type of runaway vehicle prevention device and is generally installed at the top of a slope. When the mine car is lowered to the limp point and 0.5 meters from the hydraulic brake, the hydraulic brake opens. After the mine car passes the hydraulic brake for 0.5 meters, the hydraulic brake closes. When the mine car is lifted in the opposite direction, the working principle is the opposite of the lowering, thus preventing the mine car from running away or slipping in the inclined shaft. However, the existing hydraulic car stoppers in the mine can fail to open when the mine car travels in the reverse hoisting of the inclined shaft to the position where the hydraulic car stopper is open due to a malfunction in the electrical control or hydraulic system, thus leading to hoisting accidents.

[0016] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.
[0017] Example 1: Please see Figures 1 to 4 This utility model provides a technical solution: a novel inclined shaft hydraulic vehicle stop device, including a hydraulic vehicle stop body 13, wherein the hydraulic vehicle stop body 13 is composed of a channel steel 3 and a linkage shaft 7 rotatably mounted on the channel steel 3; The channel steel 3 is provided in four sets, and the four sets of channel steel 3 are connected end to end to form a frame structure and installed in the designated position; At least one set of wheel stops 2 are installed on the linkage shaft 7; The linkage shaft 7 is located inside the frame formed by the channel steel 3, on the side closer to the mine interior. The car stop 2 is limited and flipped by the channel steel 3 on the side closer to the mine interior, so that the car stop 2 flips only towards the winch operating platform 9. When the hydraulic car stop body has an electrical or hydraulic system malfunction, it can limit the mine car.
[0018] A strong spring 6 is sleeved on the linkage shaft 7, and the two ends of the strong spring 6 are respectively connected to one of the channel steels 3 and the barrier 2. The barrier 2 is elastically connected to the channel steel 3 through the cooperation of the strong spring 6 and the linkage shaft 7. When the hydraulic car stopper body 13 experiences an electrical or hydraulic system malfunction, it can cause the car stop barrier 2 to be erected and reset, thereby limiting the movement of the mine car.
[0019] Example 2: Please see Figures 1 to 4 This utility model provides a technical solution: a novel inclined shaft hydraulic vehicle stop device, including a drive assembly for driving the linkage shaft 7 to rotate, thereby driving the vehicle stop 2 to flip. The drive assembly includes an electro-hydraulic actuator 1 disposed on one side of the hydraulic brake body 13, and a hydraulic cylinder 4 is installed on the other side of the hydraulic brake body 13. An oil pipe 8 is provided between the electro-hydraulic actuator 1 and the hydraulic cylinder 4. An extension rod is connected to the end of the linkage shaft 7 at a position above the output end of the hydraulic cylinder 4. Through the cooperation of the hydraulic cylinder 4 and the extension rod, the linkage shaft 7 is driven to rotate. A limit switch 5 is provided on one side of the hydraulic cylinder 4 to control the extension length of the output end of the hydraulic cylinder 4, thereby controlling the flipping angle of the barrier 2.
[0020] Example 3: Please see Figures 1 to 4 This utility model provides a technical solution: a novel inclined shaft hydraulic car stop device, including a traction assembly for traction of mine cars; The traction assembly includes a winch 10 disposed on one side of the hydraulic brake body 13, and a cable on the winch 10 is connected to a mine car. The traction assembly also includes a floating wheel 12 disposed between the winch 10 and the hydraulic brake body 13; The winch 10 is equipped with a depth indicator 11, which is electrically connected to the winch 10 and is used to measure the distance between the mine car and the hydraulic car stop body 13. The traction assembly also includes a winch control panel 9 installed on one side of the winch 10. The winch control panel 9 is electrically connected to the winch 10 and is used to control the winch 10. During normal lifting and transportation, when the mine car is lowered to the limp point and is 0.5 meters away from the hydraulic stop body 13, the depth indicator 11 measures the travel to 30.5 meters. The electrical control system controls the hydraulic cylinder 4 to start via the electro-hydraulic actuator 1, and then drives the stop bar 2 to flip via the linkage shaft 7. After one end of the mine car is away from the hydraulic stop body 13, the electrical control system controls the stop bar 2 to reset via the electro-hydraulic actuator 1. When the mine car is lifted in the reverse direction, the working principle is the opposite of that when it is lowered in the forward direction. When the mine car is lifted in the reverse direction, when it reaches half a meter away from the hydraulic stop body 13, the electrical control system controls the stop bar 2 to flip via the electro-hydraulic actuator 1. After the mine car passes half a meter away from the hydraulic stop body 13, the electrical control system controls the stop bar 2 to reset via the electro-hydraulic actuator 1. When an electrical or hydraulic system malfunction occurs, the weight of the mine car will press down the barrier 2, and after the mine car has passed safely, it will be mechanically reset by the strong spring 6.
