Abstract

The utility model relates to a novel bridge crane. A main beam, an end beam, and the cross beam and the longitudinal beam of a trolley are all made of shaped iron. The utility model has reasonable structure, and the peak value of stress for weld seams can be avoided. Shim plates and casing tubes are used for adjustably connecting the main beam and the end beam, as well as for adjustably connecting the cross beam and the longitudinal beam, so that the precision of the crane can be improved. The utility model has the advantages of low height for construction, good technology, adjustable structure and high precision, being a substitute product for cranes.

Description

Crane in bridge type

The utility model relates to the lifting transport field, especially a kind of crane in bridge type.

The crane in bridge type that domestic and international at present institute produces, uses, the case structure that its girder is become by the welding of four block plates, its weld seam is positioned at the stress maximum; Crossbeam on girder and end carriage and the dolly and longeron all adopt welding fixing, can not regulate, thereby the precision of known crane in bridge type also are difficult to guarantee.

The purpose of this utility model is to overcome the deficiency in the known technology and a kind of girder, end carriage, crossbeam and girder work novelty is provided, and the crossbeam of girder and end carriage and dolly and longeron can be adjusted, and makes the crane in bridge type that the hoisting crane precision is high.

The purpose of this utility model is achieved in that

Girder of the present utility model by the channel-section steel of upper and lower alignment, be welded with in it that dividing plate, its both sides are welded with web and the case structure that constitutes, end carriage is the case structure that left and right channel-section steel is welded relatively, dolly is formed four rack and panel constructions by two parallel crossbeams and two longerons of moving on girder, crossbeam is that left and right channel-section steel is welded relatively, and longeron is an I-beam section.

Be welded with convex shoulder on end carriage, be welded with an attachment strap on the girder end plate of girder end plate and end carriage convex shoulder opposite position, attachment strap rode on the convex shoulder when girder and end carriage were connected and fixed.

The backing plate that fills up on girder and the end carriage tie bolt by its connecting portion is realized adjustable.

The distance that the crossbeam of dolly and the longeron sleeve pipe by the tie bolt institute overcoat of crossbeam and longeron withstands on the longeron end plate realizes adjustable.

After crossbeam and longeron adjustment finished, Socket welding was on crossbeam.

Advantage and the good effect that the utlity model has are:

The case structure that girder is made up of channel-section steel and steel plate makes its weld seam not be positioned at stress maximum point and the easy through welding of weld seam.Needn't blanking go out the arch value adding man-hour girder web.Longeron in the dolly adopts high strength bolt, adjusting backing plate, adjusting sleeve etc. to be connected regulative mode with crossbeam, girder with end carriage, has avoided welding welding stress and the thermal deformation that is brought in the past, thereby has improved the geometric accuracy of crane in bridge type.Girder, end carriage, crossbeam, longeron can be processed separately again, thereby simplify technology and improve precision.The application of regulating backing plate and adjusting sleeve makes hoisting crane " three leg " phenomenon can not occur.Four rack and panel constructions that dolly is made up of longitudinal and cross beam, stressed clear, simple structure.

The utility model building height is little, Adjustable structure, and the precision height is the regeneration product of crane in bridge type.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

Crane in bridge type is made of the end carriage 1 of girder 3, both sides and the dolly that moves on girder, the end carriage of both sides all is equipped with electric powerplant 2, electric block 5 and electric powerplant 6 are housed on the dolly, dolly has two parallel and crossbeams 4 of moving on girder and two to constitute four rack and panel constructions with parallel longeron 8, and wheel 7 is equipped with in the crossbeam inboard.The utility model is a twin beam overhead bridge crane.

Girder of the present utility model is welded with dividing plate 17 by the channel-section steel 16 of upper and lower alignment, in it, its both sides are welded with web 18, when the processing girder, only can form an arch value to channel-section steel, web and dividing plate are burn-on gets final product again, the web blanking is gone out the arch value and needn't resemble the prior art.Dividing plate generally every one of 1.5 meters weldering, also can be stipulated as the case may be.

The utility model end carriage is the case structure that left and right channel-section steel is welded relatively, and its two side lower part is equipped with the wheel 9 that orbits.End carriage is being welded with convex shoulder 10 with the corresponding junction of girder, with the corresponding girder end plate 13 of convex shoulder on be welded with attachment strap 15, attachment strap rode on the convex shoulder when girder was connected with end carriage.Girder is such with being connected of end carriage: be welded with connecting panel 11 on the end carriage, high strength bolt 14 fastens girder and end carriage.On the high strength bolt between girder end plate and the end carriage connecting panel, backing plate 12 is arranged, the geometric accuracy when this backing plate is used to regulate girder and is connected with end carriage.

Dolly is four rack and panel constructions.Crossbeam is that left and right channel-section steel is welded relatively, and longeron is an I-beam section.The electric block that is used for lifting is housed on the dolly, one side is equipped with electric powerplant, in the crossbeam inboard wheel is housed, crossbeam is such with being connected of longeron: high strength nut 20 crosses crossbeam and is fastened on the longeron end plate 21, high strength bolt is with sleeve pipe 19 outward, this sleeve pipe withstands in the groove that the longeron end plate is shaped on, can select the casing pipe sleeve of different length as required outside bolt, and then on crossbeam welded casing, just withstand the geometric accuracy that the distance on the longeron end plate is regulated crossbeam and longeron according to sleeve pipe.
