Abstract
The invention relates to a pull rod type steel wire rope balancing device of a crane. The pull rod type steel wire rope balancing device comprises a balancing shaft support and two sets of steel wire rope mechanisms, and is characterized in that two sets of supporting shafts and balancing swing frames swinging around the supporting shafts are installed on the balancing shaft support, wherein the balancing swing frames are connected by a pull rod, and the steel wire rope mechanisms are arranged at the lower ends of the balancing swing frame. According to the pull rod type steel wire rope balancing device, the two balancing swing frames are adopted to replace one support rod in the prior art, and the stress balance of steel wire ropes at two sides can be realized as follows: the balancing swing frames swing around the respective supporting shafts by a certain angle through the pull rod connecting the balancing swing frames. The sizes of the balancing swing frames are smaller than those of balancing rods, the motion track is within the size range and does not occupy other spaces, thereby being low in influence on the ambient environment and increasing the safety coefficient; and after the two balancing swing frames are adopted, force is dispersed into two parts, the sizes of the supporting shafts are small, correspondingly, parts are small, the occupied space is small, so that machining and manufacturing are easy, and accordingly the factory investment cost is lowered.
Description
Technical field
The present invention relates to the hoisting crane field of mechanical technique, particularly relate to a kind of hoisting crane rod-pulling type steel wire rope balancing device.
Background technology:
The steel rope equalizing gear of hoisting crane usually as shown in Figure 1, the employing lever balance theory is realized, namely utilize a balance shaft and trammel beam to regulate the stressed of both sides steel rope, its operation logic is: when both sides steel rope unbalance stress or length were variant, trammel beam was realized both sides steel rope stress balance by swinging certain angle around balance shaft.Owing to the balancing length of a member and stressed concentrating, so that balance shaft and balance shaft support are all large, installation easy and the fixed pulley group produces to be interfered, and usually has to they are piled up to get up to place; Because trammel beam is long, cause in the lever work amplitude of oscillation large in addition, so not only the motion position of getting up to take up room is large, needs the factory building superjacent air space reserved large, and the factory building cost is just high, and produces easily potential safety hazard.
Summary of the invention:
The object of the invention is to overcome the defective of above-mentioned prior art, provide a kind of effective solution lever amplitude of oscillation large problem, take up room thereby dwindle motion, remove potential safety hazard, reduce the hoisting crane rod-pulling type steel wire rope balancing device of factory building cost.
The technical scheme of taking for achieving the above object is:
A kind of hoisting crane rod-pulling type steel wire rope balancing device, comprise balance shaft support and two cover steel rope mechanisms, it is characterized in that: the balance rocker that two cover pivot shafts is installed on the described balance shaft support and swings around pivot shaft, connect by pull bar between the balance rocker, steel rope mechanism is installed in balance rocker lower end.
The present invention adopts two balance rockers to replace a strut bar of the prior art, is pullling mutually the rear stress balance of realizing the both sides steel rope around the certain angle of pivot shaft swing separately by the pull bar that connects them.Because balance rocker size is little more many than trammel beam, its path of motion does not take other space in its range of sizes, and little on the ambient environment impact, safety factor increases; After adopting simultaneously two balance rockers, power is separated into two, and the pivot shaft size is just little, and corresponding parts are all little, and the locus that takies also diminishes, and processing and fabricating has also reduced the plant investment cost accordingly easily.

Fig. 1 is the structural representation sketch of prior art steel wire rope balancing device;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the structural representation sketch of hoisting crane rod-pulling type steel wire rope balancing device of the present invention;
Fig. 4 is the left view of Fig. 3.
The specific embodiment:
Hoisting crane rod-pulling type steel wire rope balancing device of the present invention comprises pivot shaft support 5 and two cover steel rope mechanisms 2, and the balance rocker 4 that two cover pivot shafts 3 is installed on the described pivot shaft support 5 and swings around pivot shaft connects by pull bar 7 between the balance rocker 4.A cover steel rope mechanism 2 is installed by the axle connection mode in each balance rocker 4 lower end.When both sides steel rope unbalance stress or length are variant, thereby then two balance rockers 4 are being pullled each other by pull bar 7 and are swung certain angle around separately pivot shaft and realize both sides steel rope stress balance.In this process, only in its range of sizes, so potential safety hazard is little, and it is highly little to take up room for the running orbit 6 of balance rocker, and fixed pulley group 1 also can be placed side by side with it at this moment.
