Abstract
The invention provides a bridge-type through four-track single-beam crane. The single-beam crane comprises a girder-type open web single beam, an elevating device and a trolley, wherein the lower end parts of the two sides of the girder-type open web single beam are provided with T-shaped steel track seats respectively; square steel tracks are arranged on the two sides of each T-shaped steel track seat; inner travelling wheels and outer travelling wheels of the trolley are arranged on the square steel tracks and connected with a trolley rack through connecting plates on the inner side and the outer side and a pin shaft; the elevating device is arranged on the trolley; and the trolley is hung on the lower part of the girder-type open web single beam. Because the elevating device and the running trolley are hung on the lower part of the girder-type open web single beam, a space conventionally occupied by the running trolley is reduced and construction cost of a workshop is saved; a statically determinate structure with three supporting points is adopted in the trolley rack, so accuracy requirement on a steel structure is lowered and the trolley rack can be simply and conveniently manufactured; and simultaneously, cylindrical surfaces of the travelling wheels of the trolley are in line contact with the tracks, so the travelling wheels have the advantages of stable running, and long service life and are suitable for elevating devices, such as an overhead crane and a gantry crane.
Description
Technical field
The present invention relates to hoisting crane, especially a kind of bridge-type through four-track single-beam hoisting crane.
Background technology
Existing hoisting crane adopts up vehicle structure mostly, and the operation of up dolly will take bigger space, increases building cost.Four fulcrum type vehicle structures commonly used, two girders of requirement metal construction bridge do not produce in the time of must having identical pre-arch curve and handling and rock, otherwise easily form the travelling wheel phenomenon that rail and wheel load suddenly increase that falls, and conventional travelling wheel adopts taper shape more, with the track face of joint is that point contacts, rocking property is big, and is easy to wear, the fault rate height.
Summary of the invention
Purpose of the present invention just provides that a kind of productive costs is low, long service life, operate steadily, and bridge-type through four-track single-beam hoisting crane applied widely.
Bridge-type through four-track single-beam hoisting crane of the present invention, comprise truss-like single-beam on an empty stomach, jack up unit, dolly, the truss-like bottom of single-beam both sides on an empty stomach is provided with the T-steel railroad shoe respectively, the both sides of T-steel railroad shoe are equipped with the square steel track, in the dolly, outer travelling wheel is placed on the square steel track, in the dolly, outer travelling wheel is by inside and outside side connecting plate, bearing pin links to each other with trolley frame, inside and outside side connecting plate lower end links to each other with trolley frame by bearing pin, walk in inside and outside side connecting plate upper end and the dolly, walking wheel shaft outward connects, outer side connecting plate is screwed on trolley frame longeron side plate, being enclosed within on the bearing pin of interior side connecting plate activity, but automatic capturing wheel track contact point, make the wheel load equilibrium, jack up unit is arranged on the dolly, and dolly is suspended on truss-like single-beam bottom on an empty stomach.
Bridge-type through four-track single-beam hoisting crane of the present invention, because jack up unit and running trolley are suspended on truss-like single-beam bottom on an empty stomach, reduced the shared space of conventional up trolley travelling, save the building cost in workshop, trolley frame adopts three fulcrum statically determimate structures, has reduced the accuracy requirement of steel structure, make easy, simultaneously the dolly travelling wheel is that the face of cylinder is that line contacts with track, operates steadily, long service life hoisting device such as suitable bridge machine, transfer crane.
