Description
Technical field
The utility model relates to hoisting crane, is specifically related to a kind of mono beam overhead crane large vehicle walking device.
Background technology
The structure design of mono beam overhead crane large vehicle walking device plays crucial effects to the performance of hoisting crane.There is following problem in the structure design of mono beam overhead crane large vehicle walking device commonly used at present:
1, its box end carriage by the U-lag beam with place the flange plate of end opening to be welded to form, to use different particular manufacturing crafts to form for its different U-shaped sectional dimension of hoisting crane of different series specification by block plate compacting, complex manufacturing, tooling cost are higher relatively.And, do not meet the requirement of GB3811 " hoist design specification " about " flange plate of welded grider and the butt weld of web should not be on the same cross section, and its spacing is not less than 200mm " because horizontal three weld seams of beam section overlap.
2, girder is assemblied in end carriage span centre inboard by connecting panel that is welded in beam-ends and cooperating through bolted connection of the connecting panel that is welded in the end carriage inboard, since the horizontal side force of end carriage only be vertically downward power about 1/10, the setting of side connecting plate makes the horizontal moment of inertia of end carriage excessive in its end carriage, cause the end carriage Cross section Design unreasonable, exist the end carriage sectional area big, the problem that deadweight increases.And its girder is connected in the processing and the strictness of assembling Geometrical Tolerance Principle of end carriage span centre inside structure, mounting process complexity.
3, its girder is installed on the end carriage span centre, four wheel wheel loads of hoisting crane are same value, because of manufacturing errors, the transportation distortion, use reason such as distortion to make wheel tread not on same plane or user's track when just having error all the year round, can make a certain wheel unsettled, when the one adhesion wheel is unsettled, will cause gnaw, slide down or cart operation asynchronous, influence the normal operation of hoisting crane.
4, the walking driver train adopts three grades of dead axle line train retarders, and size, form and position tolerance between each bearing position of its train and each axis easily exert an influence to product design, and exist volume and weight big, the problem that efficient is relatively low.
In addition, the axle hole brace panel on its end carriage is arranged at the outside of web, makes surperficial neat and artistic being affected of end carriage, also is a problem that needs solution.
Summary of the invention
At the problems referred to above, it is a kind of reasonable in design that the utility model provides, and is convenient to production and processing and adjustment is installed, and can guarantee the mono beam overhead crane large vehicle walking device of device security reliability service.
The performance attractive in appearance of improving mono beam overhead crane large vehicle walking device also is a purpose of this utility model.
For this reason, the utility model provides a kind of mono beam overhead crane large vehicle walking device.It includes adhesion wheel, the driven wheel that box girder, the two box end carriages that are connected with the box girder, symmetry be installed on box end carriage both ends and is assemblied in the driver train of being made up of motor, retarder and adhesion wheel on the box end carriage, its described box end carriage by a pair of web that becomes channel steel shape respectively with placed on it and following two cover plates constitute through assembly welding respectively; Described box girder triangularity cross section, through bolted connection be horizontally placed on two box end carriages above and be bordering on adhesion wheel partially; Described retarder is a rotation axis train retarder, is fixedly installed in the inboard of box end carriage, and the output shaft of its retarder is connected with the wheel shaft of adhesion wheel through cross coupler.
The technical solution of the utility model also comprises: inboard and adhesion wheel, driven wheel phase configuration in two webs in the box end carriage are respectively equipped with the axle hole brace panel.
The utility model is compared with existing mono beam overhead crane large vehicle walking device, has following characteristics:
1, the box end carriage is bent into a pair of web of channel steel shape and is welded in above two webs respectively and following cover plate is formed by steel plate by what be oppositely arranged, and the moulding of its web can be finished by general angle bender, and forming process is simple, and productive costs is low.And the last lower flange of this structure web not only makes good looking appearance, and the moment of inertia of beam is improved significantly.In addition, unitized construction of cover plate and two webs is convenient to cross weld is staggered about it, meet the requirement of GB3811 " hoist design specification " about " flange plate of welded grider and the butt weld of web should not be on the same cross section, and its spacing is not less than 200mm ".
2, adopt girder is ridden over master, end carriage mounting structure on the end carriage, its end carriage bears vertical pressure, meet GB3811 " hoist design specification " about " main carrying structure engineering stress ask simple, stressed clear and definite, power transmission is direct " requirement, and its mounting structure is because connecting panel is welded on the end carriage top, help increasing intensity, the rigidity of end carriage, and make things convenient for the installation adjustment of girder.In addition, adopt girder is ridden over mounting structure on the end carriage, under same high track situation, can increase lifting altitude, help reducing engineering cost.
3. the mounting structure that girder is bordering on partially adhesion wheel is adopted in assembling main, end carriage, make the adhesion wheel wheel load greater than driven wheel, can solve by wheel tread not on same plane or track unsettled problem of contingent driving wheel when being uneven, guarantee the operation of crane safety failure-free.
4, driver train adopts rotation axis train retarder, the speed reduction gearing body is a swivel, swivel axis and speed reduction gearing center shaft and the dead in line of bearing position, there is not the influence of size between each bearing position of dead axle line train and the axis, form and position tolerance, and has the advantage that structural volume is little, in light weight, efficient is high product design.
5, adopt vehicle wheel axis hole brace panel is arranged at the structure of end carriage two web inboards through welding, when realizing reducing wheel shaft opposite end web extrusion stress, improving end carriage moment of inertia purpose, help the neat and artistic of end carriage.
