Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 1 and 2, the present invention provides an embodiment: a crane cart anti-collision braking device comprises a braking iron shoe 1 and further comprises a hollow box body 2 which is arranged on a crane cart end beam and is provided with an open lower surface, the right side surface of the hollow box body 2 is open, a first connecting rod 3 is movably hinged on the inner rear surface of the hollow box body 2, the tail end of the first connecting rod 3 is hinged with a second connecting rod 31, the tail end of the second connecting rod 31 is fixedly hinged with the front end of the braking iron shoe 1, and the tail end of the braking iron shoe 1 is arranged on the outer side of the hollow box body 2; a fixing plate 5 is fixed at the upper end of the left side surface of the hollow box body 2 through a first connecting bolt 4, a central shaft 6 penetrates through the middle of the fixing plate 5, positioning clamps 7 for preventing the central shaft 6 from being separated from the hollow box body 2 are arranged at the upper end and the lower end of the peripheral side wall of the central shaft 6, the positioning clamps 7 are positioned in the hollow box body 2, a buffer block 8 is arranged at the left end of the central shaft 6, the buffer block 8 is perpendicular to the central shaft 6, a spring 9 is sleeved on the central shaft 6, and the spring 9 is arranged between the buffer block 8 and the fixing plate 5; the upper surface of the brake shoe 1 is connected with the lower end of the right side surface of the central shaft 6 through a steel wire rope 10. The feasible when not bumping, center pin 6 is fixed braking skate 1 through wire rope 10, after the hoist bumps, buffer block 8 moves right and compresses spring 9, make buffer block 8 promote center pin 6 and move right and stretch out, because the distance of center pin 6 and braking skate 1 shortens, wire rope 10 pine takes off, braking skate 1 is under the action of gravity, freely transfer, because the inertial action of hoist cart, the cart wheel can continue to advance left, advance left along with the cart wheel, make the braking skate can block the wheel of hoist, prevent that the wheel from advancing left, thereby realize the buffering of hoist and in time make the effect of stopping.

The utility model discloses the distance between well braking skate 1 and the cart wheel is less than the swing range that head rod 3 drove the removal of second connecting rod 31, and that is to say before cart wheel moves left and drives braking skate 1 and continue to move left, cart wheel has blocked on braking skate 1 to the system of hoist has been realized and has been stopped.

The utility model provides a movable hinge is common articulated mode among the prior art with fixed articulated, and the technical personnel in the field have been can clearly understood, do not carry out the detailed description here, just the utility model protects be that the crane cart prevents bumping arresting gear's structural feature.

Referring to fig. 1 and 2, in an embodiment of the present invention, the hollow box 2 is fixedly mounted on the end beam of the crane cart via a second connecting bolt 11. So that the hollow box 2 can be fixed on the crane cart end beam by the action of the second connecting bolt 11.

The utility model provides a braking skate 1 is the braking instrument of control vehicle among the prior art, can be that electronic hydraulic pressure prevents wind the iron wedge, but is not limited to here, and the technical personnel in the field can clearly understand, does not carry out the detailed description here, just the utility model protects be that the crane cart prevents bumping arresting gear's structural feature.

The utility model discloses a theory of operation: when the crane is used, the tail end of one side of the central shaft is connected with the brake iron shoe through the steel wire rope, the brake iron shoe is fixed in a horizontal state through the movable first connecting rod and the movable second connecting rod, after the crane collides, the buffer block moves rightwards to compress the spring, so that the buffer block can push the central shaft to move rightwards and stretch out, the distance between the central shaft and the brake iron shoe is shortened, the steel wire rope is loosened, the brake iron shoe is freely released under the action of gravity, and along with the leftward forward movement of the cart wheels, because the distance between the brake iron shoe and the cart wheels is smaller than the swinging amplitude of the first connecting rod driving the second connecting rod to move, the brake iron shoe is still stopped at a falling position when the cart wheels move leftwards, so when the cart wheels of the crane continue to move leftwards, the brake iron shoe can block the wheels of the crane, the cart wheels are prevented from moving leftwards, and, the buffer and timely braking action of the crane can be realized.

The above is only the preferred embodiment of the present invention, and all the equivalent changes and modifications made according to the claims of the present invention should be covered by the present invention.
