Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Example: Figures 1 to 5 The mine car anti-slip catcher shown includes: a catch fixing assembly 1, a movable linkage assembly 2, a hook body assembly 3 and a rope grab base plate assembly 4. The catch fixing assembly 1 is fixed on the longitudinal beams at the front and rear ends of the mine car. One hook body assembly 3 is respectively connected to two movable connection assemblies 2. The two movable linkage assemblies 2 are respectively connected to the chain links of the front and rear mine cars through pins. The rope grab base plate assembly 4 includes a steel wire rope 41 and a triangular grab hook 42. A steel wire rope 41 passes through the hook body assembly 3 and passes through the catch fixing assembly 1 of a mine car, passes around the catch fixing assembly of the adjacent mine car and passes through the hook body assembly, forming a T shape. The two ends of a steel wire rope 41 are located at the bottom end of the hook body assembly, and a triangular grab hook 42 is provided on each end.
[0024] like Figure 2 As shown, the capture and fixation assembly 1 includes a T-shaped connection frame 11, a pair of hanging ears 12 and a rope winding pin 13. A connection hole 14 is set on the horizontal plate of the T-shaped connection frame 11. The pair of hanging ears 12 is fixed on the top of the vertical plate of the T-shaped connection frame 11. A rope winding pin 13 is limited in the pair of hanging ears. The connection hole of the capture and fixation assembly is used to connect the longitudinal beam of the mine car, and the rope winding pin is used to connect the wire rope.
[0025] like Figure 3 As shown, the movable linkage assembly 2 includes a square housing 21, a vertical rotation pin hole 22 is provided on the square housing 21, and a pair of connecting ears 23 are provided on the right side for connecting the mine car; Figure 4 As shown, the hook assembly 3 includes a square tube 31, a pair of connecting pin holes 32 are provided on the square tube, and a pair of rope clamping tubes 33 are provided at the middle top; Figure 1 As shown, two square shells are sleeved in the square tube body, and the two connecting pin holes correspond to the rotating pin holes respectively and are connected by a pin shaft. A steel wire rope 41 passes through the rope clamping tube 33 of the hook body assembly 3 and passes through the rope winding pin shaft 13 of the capture and fixing assembly 1 of a mine car, passes through the rope winding pin shaft 13 of the capture and fixing assembly of the adjacent mine car, and then passes through the rope clamping tube 33 of the hook body assembly, forming a T shape. A rope clamp 5 is provided at the folded rope where the steel wire rope passes through the rope winding pin shaft. Rope clamps 6 are provided at both ends of a steel wire rope, located above the triangular grab hook 42, and the rope clamping tube limits the rope clamp to prevent the steel wire rope from escaping.
[0026] Usage process: When the mine car is ready to run, two adjacent mine cars are connected with two movable linkage assemblies and a hook assembly by a mine car connecting pin, and a steel wire rope is also connected to the capture and fixation assembly and the hook assembly in a T shape. At this time, the triangular grab hooks at both ends of a steel wire rope are 200 mm away from the sleepers, avoiding the slope and three gears on the tunnel floor, and the device does not work. When the mine car is unhooked, the triangular grab hook of the rope grab bottom plate assembly quickly grabs the sleepers under the mine car track, and the capture and fixation assemblies are connected to the two adjacent mine cars. The two capture and fixation assemblies are pulled by steel wire ropes, and the two adjacent mine cars are also connected by a movable linkage assembly and a hook assembly.
