Vehicle-mounted integrated mine car arrester

Abstract

The utility model discloses a vehicle-mounted integrated mine car stopper which is composed of a mine car fixing ring, a hanging chain, a hook and a car stopping bolt. When in use, the car stopping bolt is inserted into the straight slotted hole of the hollow mine car wheel, the straight slotted hole-shaped boss is arranged on the car stopping bolt, and the car stopping bolt cannot be taken out after being inserted into the straight slotted hole of the hollow mine car wheel and rotated by a certain angle. The hollow mine car wheel is prevented from rotating by limiting the length of the hanging chain and matching with the car stopping bolt. And when not in use, the car stopping bolt can be taken out from the hollow mine car wheel straight slot and hung on the hook. The utility model can effectively solve the problems that the conventional tramcar stopper is unstable to fix with a rail surface and is easy to lose, and the existing vehicle-mounted integrated tramcar stopper is complicated in structure, high in manufacturing cost and time-consuming and labor-consuming in installation.

Description

Technical Field

[0001] The utility model relates to the technical field of mine car stoppers, in particular to a vehicle-mounted integrated mine car stopper. Background Art

[0002] Most of the existing mine car stoppers are arc-shaped stoppers, which are mostly in contact with the rail surface, and have problems such as unstable fixation to the rail surface and easy loss. In addition, the existing vehicle-mounted integrated mine car stoppers have a complex structure and are inconvenient to process and manufacture. For example, the Chinese utility model patent with announcement number CN220947996U discloses "an integrated mine car stopper", whose brake assembly includes a housing, a drive box, a fixing plate, a fixing bolt, a slide, a hydraulic cylinder, a piston rod, a connecting plate, a support plate, a sleeve, a slider, a brake block, a spring, a controller and a signal transmitter, etc. This integrated mine car stopper has a complex structure, uses many parts, has a high processing and manufacturing cost, and is time-consuming and labor-intensive to install. Utility Model Content

[0003] In order to solve the problems of unstable fixation and easy loss of existing mine car stoppers to the rail surface, and to solve the problems of complex structure, high manufacturing cost, and time-consuming and labor-intensive installation of existing vehicle-mounted integrated mine car stoppers, the utility model provides a vehicle-mounted integrated mine car stopper, which is simple to manufacture and install, easy to operate, and can be taken out at any time without hanging up.

[0004] The technical solution adopted by the utility model to solve the technical problem is: a vehicle-mounted integrated mine car blocker, including a blocker pin and a hanging chain connected to the blocker pin body. There are straight groove hole-shaped bosses at both ends of the blocker pin, and a fixing ring is provided on the straight groove hole-shaped boss at one end of the blocker pin to connect with the hanging chain. The other end of the hanging chain is connected to the mine car fixing ring, and a hook is provided below the mine car fixing ring, and the blocker pin can be hung by the blocker pin fixing ring when not in use.

[0005] The above-mentioned vehicle-mounted integrated mine car stopper, the said car-stopping pin is made of rigid material, the middle part of the car-stopping pin is cylindrical and the length is equal to the thickness of the hollow mine car wheel, and straight slot hole-shaped bosses are provided at both ends. The size of the straight slot hole-shaped bosses is slightly smaller than the straight slot hole of the mine car wheel. When the line connecting the centers of the two arcs of the straight slot hole-shaped bosses is parallel to or coincides with the line connecting the centers of the arcs of the straight slot hole of the mine car wheel, the car-stopping pin can pass through the straight slot hole of the mine car wheel. When the car-stopping pin is rotated to a certain angle, it cannot be taken out of the straight slot hole of the mine car wheel.

[0006] The above-mentioned vehicle-mounted integrated mine car blocker has one end of the hanging chain connected to the fixing ring of the blocking pin and the other end linked to the fixing ring of the mine car. The length of the hanging chain is the shortest distance between the fixing ring of the mine car and the center of the nearest straight slot hole of the mine wheel. The length of the hanging chain can ensure that the blocking pin is inserted into the straight slot hole of the mine wheel. After the blocking pin is inserted into the straight slot hole of the mine wheel, the rotation of the mine wheel is restricted by the hanging chain. The line connecting the centers of the two arcs of the straight slot hole-shaped boss and the line connecting the centers of the arcs of the straight slot hole of the mine wheel are rotated to be parallel or coincident, and the blocking pin can be taken out and hung on the hook. This type of vehicle-mounted integrated mine car blocker can be provided with one set on each side of the mine car compartment.

[0007] The beneficial effects of the utility model are low manufacturing cost, simple installation, ready-to-use, not easy to lose, and convenient operation and use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0014] A vehicle-mounted integrated mine car stopper includes a mine car fixing ring 2, a hanging chain 3, a hook 4, and a car stop pin 6. The car stop pin 6 has straight groove hole-shaped bosses 6-2 at both ends, and a car stop pin fixing ring 6-1 is provided on the straight groove hole-shaped boss 6-2 at one end and connected to one end of the hanging chain 3. The middle part 6-3 of the car stop pin is cylindrical and its length is equal to the overall thickness of the hollow mine car wheel 5. The other end of the hanging chain 3 is connected to the mine car fixing ring 2, and a hook 4 is provided below the mine car fixing ring 2. When the car stop pin 6 is not in use, it can be hung on the hook 4 through the car stop pin fixing ring 6-1. The size of the straight slot hole-shaped boss 6-2 is slightly smaller than the straight slot hole 5-2 of the mine wheel. When the connecting line of the two arc centers of the straight slot hole 5-2 of the straight slot hole 5-2 is parallel to or coincides with the connecting line of the arc centers of the straight slot hole 5-2 of the mine wheel, the boss 6-2 can pass through the straight slot hole 5-2 of the mine wheel. After the blocking bolt 6 passes through the straight slot hole 5-2 of the mine wheel and rotates a certain angle, it cannot be taken out of the straight slot hole 5-2 of the mine wheel. One end of the hanging chain 3 is connected to the blocking bolt 6 through the blocking bolt fixing ring 6-1, and the other end is connected to the mine car fixing ring 2. The length of the hanging chain 3 is the shortest distance between the mine car fixing ring 2 and the center of the mine wheel straight slot hole 5-2 closest to it, which can ensure that the blocking bolt 6 is inserted into the straight slot hole 5-2 of the mine wheel. After the blocking bolt 6 is inserted into the hollow mine wheel 5, its rotation is restricted by the hanging chain 3. When not in use, the arc center line of the straight slot hole-shaped boss 6-2 is rotated to be parallel or coincident with the arc center line of the straight slot hole 5-2 of the mine wheel, and the car blocking pin 6 can be taken out and hung on the hook 4. This vehicle-mounted integrated mine car blocker can be set on both sides of the mine car compartment 1.
