Abstract
An electric double-beam bridge crane relates to the technical field of cranks and consists of a trolley, driving wheels, driven wheels, a crane operating mechanism, a crane span structure and side guiding buffer seats. The crane span structure comprises main beams and end beams, the end beams are arranged at two ends of each main beam, the end beams are provided with the driving wheels, the driven wheels and the crane operating mechanism, and the trolley is disposed on guide tracks of the main beams. The electric double-beam bridge crane is characterized in that the side guiding buffer seats are mounted on steel tracks at two ends of each end beam, wheels of the trolley and the driving wheels are wheels without flanges, and the end beams are integral structures. The electric double-beam bridge crane is simple and reasonable in structure, the side guiding buffer seats are adopted, when rollers of side guiding buffer seats contact with side surfaces of the guide tracks, running directions of the trolley and the driving wheels are changed in a rolling friction mode, so that friction resistance is low, sliding friction noise of flanges of originally designed wheels is avoided, a gap between each roller and each steel track is controlled in a range between 2mm to 3mm, snakelike running is avoided, the end beams are the integral structures, during transport of the crane span structure, two crossbeams are omitted, the two main beams and small structural parts are added, and accordingly the electric double-beam bridge crane is convenient in transportation and construction.
Description
Technical field
The utility model relates to the hoisting crane technical field, is 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.
The utility model content
The utility model technical matters to be solved is to weak point of the prior art a kind of twin beam overhead bridge crane to be provided.
The utility model technical matters to be solved 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 beneficial effect of the utility model is: the utility model 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.

The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of twin beam overhead bridge crane is made up of dolly 5, adhesion wheel, passive wheel, crane travel mechanism 2, crane span structure 4 and side guiding buffer box 6; Crane span structure 4 comprises girder 1 and end carriage 3; End carriage 3 is arranged at the two ends of girder 1, and adhesion wheel and passive wheel and crane travel mechanism 2 are installed on the end carriage 3, and dolly 5 is located on girder 1 guide rail; Installation side guiding buffer box 6 on the rail 7 at end carriage 3 two ends; The wheel of dolly 5 and adhesion wheel are no rib wheel, and end carriage 3 is an integral structure, and end carriage 3 is used the articulation hole bolted connection with girder 1.
