Abstract
The utility model relates to a movable counterweight balance lifting crane, in particular to an improvement of a counterweight balance lifting crane. The utility model aims at solving the problems of the existing counterweight balance lifting crane that the stability and the safety are poor and providing the balance lifting crane which has movable counterweight, better stability and safety. The utility model comprises a tower body, and a truss revolving mechanism arranged on a shaft of a bracket is arranged on the top end of the tower body. The utility model has a main structure that the counterweight is arranged on a rail of the truss through a pulley, and a motor shaft on the truss is connected with the counterweight through a string; a micro switch which controls a movement of the motor is arranged in a spring between the truss and the bracket of the revolving mechanism.
Description
Technical field:
The utility model just relates to the improvement of counterweight balance lifting crane structure.
Background technology:
The balance position of present lifting crane is fixed, and away from body of the tower the time, the weight of slinging is relatively few, and when body of the tower is nearer, the weight of slinging is just more, and the stability of body of the tower, safety are relatively poor, and this brings very big inconvenience to the user.
Summary of the invention:
The utility model is exactly the relatively poor problem of stability, safety that solves present counterweight balance lifting crane, provide a kind of counterweight movably, good stability, balance lifting crane that safety is good.
The utility model adopts following technical scheme: the utility model comprises body of the tower, the top of body of the tower has the rotating mechanism of the frame that spreads out on the axle that is arranged on support, its structural feature is that counterweight is arranged on the track of the frame that spreads out by pulley, link to each other with cotton rope between axle and the counterweight of motor on the frame of spreading out, have the micro-switch of controlling motor movement in the support of rotating mechanism and the spring between the frame of spreading out.
The beneficial effects of the utility model:
Because the utility model rotating mechanism is provided with micro-switch, spread out and movable balance weight is set on the frame, just can make distance, the weight mobile counterweight of this crane, just guarantee stability, the safety of crane, also improve the work efficiency of crane with hoisting heavy.

The specific embodiment:
The utility model comprises body of the tower 1, the top of body of the tower 1 has the rotating mechanism 11 of the frame 8 that spreads out on the axle 10 that is arranged on support 9, counterweight 4 is arranged on the track 6 of the frame 8 that spreads out by pulley 5, link to each other with cotton rope 3 between axle and the counterweight 4 of the motor 2 on the frame 8 of spreading out, have in the support 9 of rotating mechanism 11 and the spring 12 that spreads out between the frame 8 and control the micro-switch 14 that motor 2 moves.
One end of cotton rope 3 can be fixed on the side 13 of counterweight 4; Cotton rope 3 can be walked around pulley 7 on the axle on the motor 2 and the frame 8 that spreads out, link to each other with counterweight 4.
Narrate a course of action of the present utility model below:
When slinging weight, rotating mechanism 11 is with regard to lack of equilibrium, micro-switch 14 just action, actuating motor 2 mobile counterweights 4, reach balance; After weight landed, rotating mechanism 11 is lack of equilibrium again, counterweight 4 under micro-switch 14 control actuating motor 2, mobile counterweight 4 to corresponding position.
