Embodiment Construction
[0010] Such as figure 1 , 2 As shown, the front end of the frame 11 is hinged to the bumper 1 through the hinge shaft 3, the hinge shaft 3 is covered with a torsion spring 2, the rear end of the bumper 1 has a lock shaft 5, the lock shaft 5 is pushed by the upper end of the unlocking lever 4, and the unlocking lever 4 The lower end of the lower end is hinged with the frame 11, and the unlocking lever 4 is knocked open, so that the unlocking lever 4 is disengaged from the lock shaft 5, and the torsion spring 2 can make the bumper 1 lift up quickly, and be in a position perpendicular to the plane 8 on the frame 11; after the bumper 1 Lever 6 is hinged on the frame 11 at the end, and the lower end of lance 6 fixes bumper 7, and the front end of bumper 7 is close to described unlocking lever 4, so that bumping unlocking lever 4, unlocking lever 4 is disengaged from lock shaft 5.
[0011] Described bumper 7 and frame 11 are hinged by two-way torsion spring (not shown in the figure...

The invention relates to an inclined drift overspeed bumping head car arrester. The front end of a frame is hinged to a bumping head through a hinge shaft, the hinge shaft is sleeved with a torsional spring, a lock shaft is arranged at the rear end of the bumping head, the lock shaft is supported by the upper end of an unlocking rod, the lower end of the unlocking rod is hinged to the frame, the unlocking rod is forced open, the unlocking rod and the lock shaft are separated, the torsional spring enables the bumping head to be rapidly lifted to be located at the position perpendicular to the upper plane of the frame, a bumping rod is hinged to the frame at the rear end of the bumping head, a bumping block is fixedly arranged at the lower end of the bumping rod, the front end of the bumping block is close to the unlocking rod, and therefore the unlocking rod is bumped conveniently, and the unlocking rod and the lock shaft are separated. The inclined drift overspeed bumping head car arrester is simple in structure, small in size and capable of preventing inertia car sliding.
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 a car arrester for speeding bumps in inclined lanes, which has a simple structure and a small volume, and can prevent the car from coasting. [0004] The technical solut...
