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 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 conventionally as shown in Figure 1, employing lever balance theory is realized, 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 are when variant, trammel beam is realized both sides steel rope stress balance by swing certain angle around balance shaft.Due to the balancing length of a member and stressed concentrating, make balance shaft and balance shaft support all large, installation easy and fixed pulley group produces to be interfered, and usually has to them to pile up to get up to place; In addition because trammel beam is long, cause in lever work the amplitude of oscillation large, so not only the motion position of getting up to take up room is large, needs reserved factory building superjacent air space large, and factory building cost is just high, and easily produces potential safety hazard.
summary of the invention:
The object of the invention is to overcome the defect of above-mentioned prior art, provide a kind of effective solution lever amplitude of oscillation large problem, thereby dwindle motion, take up room, remove potential safety hazard, reduce the hoisting crane rod-pulling type steel wire rope balancing device of factory building cost.
The technical scheme taked is for achieving the above object:
A kind of hoisting crane rod-pulling type steel wire rope balancing device, comprise balance shaft support He Liangtao steel rope mechanism, it is characterized in that: the balance rocker that two cover pivot shafts is installed on described balance shaft support and swings around pivot shaft, between balance rocker, by pull bar, connect, steel rope mechanism is arranged on balance rocker lower end.
The present invention adopts two balance rockers to replace a strut bar of the prior art, after pullling mutually, around pivot shaft separately, swings the stress balance that certain angle realizes both sides steel rope by the pull bar that connects them.Because balance rocker size is little more many than trammel beam, its path of motion, in its range of sizes, does not take other space, and little on ambient environment impact, safety factor increases; Adopt after two balance rockers, power is separated into two simultaneously, and pivot shaft size is just little, and corresponding parts are all little, and the locus taking also diminishes, and easily processing and fabricating, has also reduced plant investment cost accordingly.
accompanying drawing explanation:
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 He Liangtao steel rope mechanisms 2, and the balance rocker 4 that two cover pivot shafts 3 is installed on described pivot shaft support 5 and swings around pivot shaft, connects by pull bar 7 between balance rocker 4.A set of steel rope mechanism 2 is installed by axle connection mode in each balance rocker 4 lower end.When both sides steel rope unbalance stress or length are when variant, thereby then two balance rockers 4 are being pullled each other and around pivot shaft separately, to be swung certain angle and realize both sides steel rope stress balance by pull bar 7.In this process, the running orbit 6 of balance rocker is only in its range of sizes, therefore potential safety hazard is little, and it is highly little to take up room, and now fixed pulley group 1 also can be placed side by side with it.
