Abstract
The invention relates to an assembly-type large-span heavy-load gantry crane, which comprises a traveling beam arranged in parallel, a lower supporting boot positioned and connected on the traveling beam, and a traveling wheel; the assembly-type large-span heavy-load gantry crane is characterized in that: a supporting leg of the crane is formed by connecting universal rod pieces; the lower end of the supporting leg is connected with the lower supporting boot, while the upper end is connected with an upper supporting boot; the bottom platform of an operating room is also formed by connecting universal rod pieces and is connected with the supporting leg into a whole; and a main beam of the crane adopts a main beam of a bridge girder erection machine, and a crown block is arranged thereon. The assembly-type large-span heavy-load gantry crane has the advantages that: a gantry crane can be assembled according to different spans and loads; the structure is simple and clear; the large-span and heavy-load construction requirement can be met; the cost is saved, the structure is simple, the assembly is fast and the assembling time is shortened by adopting the traditional bridge girder erection machine to assemble; the operation is simple and flexible because of the adoption of the operating system of the bridge girder erection machine; and the overall structure has strong stability.
Description
Technical field
The present invention relates to elevator machinery, be specifically related to a kind of assembly-type large-span heavy-load gantry crane.
Background technology
The general maximum span of transfer crane commonly used in the construction is 25m, and the maximum allowable load is 60t.In construction, run under the bigger situation of span; the normal girder that adopts shellfish thunder beam spelling transfer crane; though this spelling transfer crane has solved the problem of span, usually can be less, lateral stability is relatively poor etc., and shortcoming is subjected to various restrictions because of the load allowable of its Bei Leiliang.If adopt the large span of typing, the transfer crane of heavy load, though both can solve the problem of span, can solve the problem of heavy load again, but, the transfer crane of the baroque large span of this typing, heavy load is transported to the camp site to be installed and used, the time that not only needs is long, and the cost height; In addition, the operating needs height of this transfer crane, the condition of camp site can not satisfy usually, so, use to be subjected to many restrictions.
Summary of the invention
The purpose of this invention is to provide a kind of assembly-type large-span heavy-load gantry crane, big, the allowable load of its span is big, safety performance is high; Structure is simple and clear, spelling is efficient and convenient, easy and simple to handle; Can enhance productivity, reduction of erection time, cost-cutting; Use the relatively poor camp site of the condition that is specially adapted to.
A kind of assembly-type large-span heavy-load gantry crane of the present invention, comprise the walking beam that is arranged in parallel, be located by connecting on lower support boots above the walking beam, be located by connecting on road wheel below the walking beam, be located on the road wheel and be mated bonded assembly motor and retarder, road wheel cooperates with walking track on being located by connecting on sleeper, it is characterized in that:
The supporting leg of this hoisting crane adopts fabricated universal steel members to be formed by connecting, and the lower end of supporting leg is connected with the lower support boots, and the upper end of supporting leg is connected with the upper support boots;
The bottom platform of the operator's compartment of this hoisting crane also adopts fabricated universal steel members to be formed by connecting, and is connected to an integral body with supporting leg;
The distribution beam of this hoisting crane is welded by two back-to-back channel-section steels, and is located by connecting with the upper support boots;
The girder of this hoisting crane adopts the girder of bridge formation machine to form, and girder is located by connecting on the distribution beam, which is provided with overhead traveling crane.
Described a kind of assembly-type large-span heavy-load gantry crane, its girder is the girder of existing bridge formation machine.The model that adopts Kaifeng machine works of HTC to produce is the large-tonnage of HD120T/50m, the girder of large span bridge formation machine, selects the joint number of girder according to the span of this hoisting crane.
The walking track adopts the 43kg/m rail, is fixed on the sleeper by supporting track plate, railway spike; Walking beam is the box beam that shaped steel is welded into, and is welded on the connection steel plate of road wheel as the running gear of hoisting crane, and road wheel is driven by motor and retarder.
Beneficial effect of the present invention: can carry out the spelling transfer crane according to different spans, load, structure is simple and clear, can realize the construction requirement of large span, big load, adopt the assembly unit of existing bridge formation machine to save cost, simple in structure, assembly unit is quick, shortened the set-up time, because it is simple to operate, flexible to have adopted the operating system of bridge formation machine to make, integral structure stability is stronger.
