The invention relates to an automatic stop block for front colliding and rear hooking for a mine car on inclined roadways. The front end of a framework is hinged to a front colliding head through a front shaft which is sheathed with a front torsion spring, a lock shaft is arranged at the rear end of the front colliding head, the lock shaft is born against by a front unlocking rod, and the lower end of the front unlocking rod is hinged to the framework; the front unlocking rod is bumped off, so that the front unlocking rod is broken away from the lock shaft; the front torsion spring can enable the front colliding head to uplift rapidly to be in a position which is perpendicular to the upper plane of the framework; the rear end of the framework is hinged to a hooking head through a rear shaft which is sheathed with a rear torsion spring; a lock plate is arranged at the front end of the hooking head, and is locked up by the rear end of a rear unlocking rod; the front end of the rear unlocking rod is hinged to the rear end of a colliding block, and the front end of the colliding block is close to the front unlocking rod so as to collide the front unlocking rod, so that the front unlocking rod is broken away from the lock shaft; and the colliding block is hinged to the framework, and a colliding rod is fixed on the colliding block. The automatic stop block has the advantages of simple structure and compactness, and can prevent inertia rolling of a car.
Description
technical field [0001] The invention relates to a mine car safety device, in particular to an anti-rolling car device for mine inclined lanes. Background technique [0002] In the transportation inclined lanes of the underground mining face of coal mines, there are accidents such as broken rope sports car, unpowered sports car with winch, unhooked car return, speeding car return, and unsignaled car return, etc., which seriously endanger the safety of production. The inclined roadway transportation of the mining face is a temporary transportation, the roadway section is small, the conditions are poor, and the changes are large, so the regular large-scale anti-car device cannot be used. Contents of the invention [0003] In order to overcome the disadvantages of the prior art, the present invention provides an automatic car arrester for mine car inclined lanes, which has a simple structure and small volume, and can prevent the car from coasting. [0004] The technical solut...
