Abstract

The utility model provides a kind of engineering gauntry crane dolly chain drive, comprise girder, track, described girder upper cover plate place is provided with two tracks, trolley frame moves around in orbit, chain two ends are separately fixed at the both sides of trolley frame, motor reducer drives drive sprocket, and chain connects drive sprocket and driven sprocket respectively.This patent vibrational power flow, drive sprocket and the whole series such as driven sprocket and motor reducer are contained in the termination of trolley frame travel region, monkey runs and uses chain drive, and maximum advantage is exactly the deadweight substantially reducing trolley frame, has saved the manufacturing cost of car load; Operate steadily, open brake safe reliable, extend the service life of car load.

Description

A kind of engineering gauntry crane dolly chain drive
Technical field
The utility model relates to crane drives field, particularly a kind of engineering gauntry crane dolly chain drive.
Background technology
At present, engineering gauntry crane trolley travelling generally adopts wheel group, reductor, motor and drg array configuration to drive, the driving dolly force of inertia of this form is larger, easily causes the longitudinal direction of car load to rock, affect the service life of complete machine when dolly opens braking; Cause trolley frame weight bigger than normal thus, thus affect the weight of complete machine, add manufacturing cost.
Therefore, the utility model develops on the basis mainly solving more than currently available technology existence deficiency.
Summary of the invention
The object of utility model solves above technical matters, proposes the engineering gauntry crane dolly chain drive that a kind of structure is simple, cost-saving, operate steadily especially.
Based on above-mentioned purpose, the technical matters that the utility model solves realizes by the following technical solutions:
A kind of engineering gauntry crane dolly chain drive, comprise girder, track, described girder upper cover plate place is provided with two tracks, trolley frame moves around in orbit, chain two ends are separately fixed at the both sides of trolley frame, motor reducer drives drive sprocket, and chain connects drive sprocket and driven sprocket respectively.
Further, described chain forms a closed driving system through trolley frame, drive sprocket, driven sprocket.
Further, described driven sprocket is arranged on one end of trolley frame travel region.
Further, described drive sprocket is arranged on the other end of trolley frame travel region.
Further, described chain is provided with chain clamping device.
The beneficial effects of the utility model are, this patent vibrational power flow, drive sprocket and the whole series such as driven sprocket and motor reducer are contained in the termination of trolley frame travel region, monkey runs and uses chain drive, maximum advantage is exactly the deadweight substantially reducing trolley frame, has saved the manufacturing cost of car load; Operate steadily, open brake safe reliable, extend the service life of car load.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Detailed description of the invention
Below by way of Figure of description, further set forth the utility model;
According to Fig. 1, a kind of engineering gauntry crane dolly chain drive, comprise girder 8, track 7, described girder 8 upper cover plate place is provided with two tracks 7, trolley frame 4 moves around after track 7 is gone forward, chain 3 two ends are separately fixed at the both sides of trolley frame 4, motor reducer 1 drives drive sprocket 2, chain 3 connects drive sprocket 2 and driven sprocket 6 respectively, chain 3 is through trolley frame 4, drive sprocket 2, driven sprocket 6 forms a closed driving system, driven sprocket 6 is arranged on one end of trolley frame 4 travel region, drive sprocket 2 is arranged on the other end of trolley frame 4 travel region, chain 3 is provided with chain clamping device 5.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
