Abstract
Disclosed is a crane counter weight block. Positioning structures are correspondingly arranged in four corners of the upper surface and on the lower surface of the counter weight block; and a lifting lug is arranged on the lateral surface of the counter weight block. The crane counter weight block is characterized in that mutually nested and positioned bosses and sunk holes for overlapping the weight block in up and down manner are respectively arranged in the centers of the upper surface and the lower surface of the weight block, and movement of the counter weight block in a horizontal direction is limited through nesting and limiting of the bosses and the sunk holes when two counter weight blocks are overlapped together.
Description
Technical field
The utility model relates to hoisting crane, particularly the crane counterweight piece.
Background technology
The crane counterweight piece is to realize one of vital parts that the hoisting crane load capacity promotes, steadiness that it in use fits together and safety are very important, existing clump weight generally is to increase location structure on four angles, need four angles all to exist the inclined-plane location structure could bring into play positioning action fully, simplify inadequately on the structure.
Summary of the invention
The purpose of this utility model is to design a kind of crane counterweight piece, at clump weight centre portion upper and lower surface design boss, counterbore, make two clump weights when being stacked together up and down, nested spacing by boss and counterbore limited moving on the horizontal direction of clump weight.
For achieving the above object, the technical solution of the utility model is:
The crane counterweight piece, correspondence is provided with location structure on four angles of clump weight upper and lower surface, and hanger is established in the side; It is characterized in that these clump weight upper and lower surface central authorities are respectively equipped with the boss and the counterbore of mutually nested location when supplying clump weight to stack.
Further, described boss and counterbore are circle, triangle, quadrangle or polygon.
Again, the sidewall of described boss and counterbore is the inclined-plane.
Have, described clump weight upper surface boss periphery is triangle 3 positioning convex is set again.
In addition, the medial surface of the corresponding location structure that is provided with is the inclined-plane on four of clump weight upper and lower surface described in the utility model angles.
The groove that is provided with for hanger is offered in described clump weight side.
Under gravity and chain force, the clump weight that stacks up and down is pressed together, thereby makes middle be combined together mutually nested with counterbore of boss of clump weight up and down, plays horizontal position-limiting action.
Advantage of the present utility model is:
The utility model is at clump weight centre portion upper and lower surface design boss, counterbore, the sidewall of boss and counterbore all is the bevelled inclined-plane, make two clump weights when being stacked together up and down, nested spacing by boss and counterbore, limited moving on the horizontal direction of clump weight, can realize positioning action fully as long as increase the structure that a restriction clump weight rotates again.The application of position limiting structure in the middle of this can make the structure of clump weight obtain simplifying.

The specific embodiment
Referring to Fig. 1～Fig. 6, crane counterweight piece of the present utility model, correspondence is provided with location structure 13,14 on four angles of clump weight 1 upper and lower surperficial 11,12, and hanger 2 is established in side 15; These clump weight upper and lower surface 11,12 central authorities are respectively equipped with the boss 3 and the counterbore 4 of mutually nested location when supplying clump weight to stack.The groove 151 that is provided with for hanger 2 is offered in described clump weight 1 side 15.
Described boss 3 and counterbore 4 are circular, and the sidewall 31,41 of boss 3 and counterbore 4 is the inclined-plane.Described clump weight 1 upper surface 11 boss 3 peripheries are triangle 3 positioning convex 111 are set.
Referring to Fig. 6, the medial surface 131,141 of the corresponding location structure 13,14 that is provided with is the inclined-plane on four angles of described clump weight 1 upper and lower surface 11,12.
Corresponding before and after the clump weight that will stack, there is the one side of boss all to get final product towards top being stacked together, the boss of such two clump weights and counterbore can align and nest together.Because the sidewall of boss and counterbore all is the bevelled inclined-plane, makes two clump weights when being stacked together up and down, nested spacing by boss and counterbore limited moving on the horizontal direction of clump weight.
Claims (7)
