Abstract
An electric two-beam bridge crane relates to the technical field of cranes and is composed of a trolley, driving wheels, driven wheels, a crane operation mechanism, a bridge stand and a side guiding buffer seat. The bridge stand comprises a main beam and end beams, which are disposed on two ends of the main beam and are provided with the driving wheels, driven wheels and the crane operation mechanism. The trolley is arranged on a guide rail of the main beam. The invention is characterized in that steel rails on the two ends of the end beams are equipped with the side guiding buffer seat; wheels of the trolley and the driving wheels are rib-free wheels; and the end beams have an integral structure. The invention has a simple and reasonable structure. By the adoption of the side guiding buffer seat, the operation direction of the trolley and the driving wheels is changed in the form of rolling friction when rollers of the seat contact with the side surface of the guide rail. Therefore, the frictional resistance is small and there exists no sliding frictional noise of wheel ribs by original design. In addition, the gap between the rollers and the steel rail is controlled within 2-3mm without snakelike operation phenomenon; and by the integral structure of the end beams, it is convenient to transport during bridge stand transportation when two big beams, two main beams and small structural members are removed and it is convenient for construction.
Description
Technical field
The present invention relates to the hoisting crane technical field, be specifically related to a kind of twin beam overhead bridge crane.
Background technology
The two beam crane in bridge type machine is to be widely used in places such as indoor and outdoor commercial production, storage, communications and transportation; Have effect height, use steadily, reliably; And can select main hook or auxiliary hook respectively for use according to weight of material; Energy-conservation relatively, also can select dissimilar suspenders for use according to material translation property, use extremely extensive.Electronic doube bridge formula hoisting crane (like Fig. 1) the standard No. GB/T14405 of standard; This hoisting crane is made up of dolly (like Fig. 2, Fig. 3), adhesion wheel assembling (like Fig. 4), passive wheel (like Fig. 5), crane travel mechanism (like Fig. 6), crane span structure 7 parts such as (like Fig. 6); Wherein crane span structure is made up of end carriage (like Fig. 8) and girder (like Fig. 9), and crane in bridge type is widely used in places such as indoor and outdoor commercial production, communications and transportation.It has service efficiency height, safe and reliable, not limited by surface condition, and is provided with main hook and auxiliary hook, not only can select main hook or auxiliary hook for use by weight of material, operation such as can also be used to stand up.But this machine comes from the fifties Soviet Union structure in last century, though through Renewal Design repeatedly, fundamentally change, has that operation is snakelike, noise is big, running resistance is big, girder and end carriage be welded into integral body, deficiencies such as hard transportation.
Summary of the invention
Technical matters to be solved by this invention is to weak point of the prior art a kind of twin beam overhead bridge crane to be provided.
Technical matters to be solved by this invention adopts following technical scheme to realize,
A kind of twin beam overhead bridge crane; Form by dolly, adhesion wheel, passive wheel, crane travel mechanism, crane span structure and side guiding buffer box; Described crane span structure comprises girder and end carriage, and said end carriage is arranged at the two ends of girder, and adhesion wheel and passive wheel and crane travel mechanism are installed on the described end carriage; Said dolly is located on the girder guide rail; It is characterized in that: installation side guiding buffer box on the rail at described end carriage two ends, the wheel of said dolly and adhesion wheel are no rib wheel, described end carriage is an integral structure.
Said end carriage and girder are used the articulation hole bolted connection.
Described side guiding buffer box comprises base, and said base is provided with energy disperser, and said base two bottom sides is connected with roller through axle.
Said roller is provided with back-up ring.
Said base is installed on the rail.
The invention has the beneficial effects as follows: the present invention is simple and reasonable, adopts side guiding buffer box, when this roller and guide rail contacts side surfaces; Change the service direction of dolly and adhesion wheel with the form of friction of rolling; Therefore friction drag is little, do not had the cliding friction noise of original design wheel rib, and the clearance control of roller and rail is at 2-3mm; There is not the snakelike phenomenon of operation; And end carriage adopts integral structure, goes two crossbeams to add two girders during the crane span structure transportation and adds brief summary member convenient transportation, easy construction.
