Technical Field
The utility model relates to a lifting equipment field specifically is a reduce turning radius's rail dolly that lifts by crane.
Background
The hoisting trolley is widely used in the existing industrial production, the general structure of the hoisting trolley comprises a frame, walking wheels moving along steel rails are arranged on the frame, driving mechanisms are arranged on the walking wheels, a hoisting shaft for weighing is arranged below the frame, the steel rail trolley is required to circularly move along an annular rail in some use environments, the steel rail trolley is required to turn at the moment, two groups of guide wheels are generally arranged front and back, the turning radius directly influences the occupied area of the rail, in order to save the space of a factory building, the turning radius of the steel rail trolley is reduced as much as possible, the center distance between the two groups of guide wheels greatly influences the minimum turning radius, the turning radius of the steel rail trolley more than 5 tons at present is 2 meters at the minimum, and the steel rail trolley is limited by the structure of the steel rail trolley and cannot be further reduced.
Disclosure of Invention
The utility model aims at providing a reduce turning radius's rail dolly that lifts by crane in order to further reduce turning radius in order to practice thrift the space.
The utility model has the following concrete scheme: the utility model provides a reduce turning radius's rail dolly of lifting by crane, includes the frame, and frame bilateral symmetry is equipped with two sets of walking wheels, and the walking wheel is walked along the rail both sides, and the lifting shaft is equipped with to the frame bottom, and actuating mechanism is equipped with on one side of the frame, and actuating mechanism is connected with one of them set of walking wheel, frame bilateral symmetry is equipped with two sets of leading wheel devices, and every leading wheel device quantity of group is two and installs at the frame both ends, and every leading wheel device includes the center pin, is equipped with the leading wheel through the bearing in the middle of the center pin, and a spacing bush is respectively equipped with to the bearing both sides, and the center pin both ends respectively are equipped with a mounting hole, are equipped with a set of locking bolt in every mounting hole, and the center pin passes through locking bolt to be installed at the frame inboard.
The cover is equipped with adjusting shim between last center pin that lies in of locking bolt and the frame, adjusting shim is used for adjusting the distance between leading wheel and the rail.
Every side of frame is equipped with two walking wheels side by side.
Compared with the prior art, the utility model has the following advantages: the leading wheel passes through the center pin and installs on the frame, and the center pin both ends are directly fixed through the locking bolt, have reduced connection structure, avoid connection structure and walking wheel or the ring gear of walking wheel to interfere to can reduce the centre-to-centre spacing between the leading wheel of both ends, and then reduced turning radius.
