Abstract
The invention relates to a double-beam walking trolley, comprising a square frame body, a driving shaft and a driven shaft which can be rotatably penetrated in the square frame body, driving wheels located on the outer side of the square frame body and fixed at the two ends of the driving shaft, and a motor installed in the square frame body, wherein the driving shaft and the driven shaft are mutually parallel and form a horizontal plane, the motor is engaged with one driving wheel, columnar projections are integrally fixed at the two ends of the driven shaft, the columnar projections are located on the outer side of the square frame body, the driven wheel is installed on the columnar projections, and the axle wire of the driven shaft and the axle wires of the columnar projections at the two ends of the driven shaft are mutually parallel and are not located on the same straight line. Since the axle wire of the driven shaft and the axle wires of the columnar projections at the two ends of the driven shaft are mutually parallel and are not located on the same straight line, the three-leg phenomenon generated when the walking trolley walks on double beams is overcome, the non-uniform stress condition of the walking trolley is avoided and the service life of the walking trolley is prolonged.
Description
Technical field
The invention belongs to hoisting crane technical field, be specifically related to a kind of twin beams walking dolly.
Background technology
Hoisting crane (claiming again crane) refers to many actions elevator machinery of vertical-lift within the specific limits and horizontal carrying heavy goods, for material handling, by version, can be divided into small-sized weight-lifting equipment, bridge (bridge-type, transfer crane), boom type (self-propelled, tower, seat type, railway formula, floating vessel type, derrick crane), cable type etc.Wherein, bridge crane can oblong place and on idle job, be used for the Article handling that workshop, warehouse, open storage etc. are located, be divided into beam crane, crane in bridge type, gauntry crane, cable crane, crane bridge etc., and beam crane mainly comprises mono beam crane in bridge type and twin beam overhead bridge crane.The advantage of twin beam overhead bridge crane is lifting wider range, can lift by crane the article of 1 ton ~ 100 tons, adopt twin beams walking dolly as operating unit, electric block as lifting mechanism.
In a lot of situations, twin beams is not in same level, and on beam, there is rough place, existing walking dolly there will be in the course of time and only has three wheels to contact with track while walking (especially load-carrying walking) on this beam, another unsettled (i.e. " three leg " phenomenon), make twin beams walking dolly discontinuity, affect its service life.
Summary of the invention
The present invention seeks in order to overcome the deficiencies in the prior art, to provide a kind of and do not occur the twin beams walking dolly of " three leg " phenomenon.
For achieving the above object, the technical solution used in the present invention is: a kind of twin beams walking dolly, comprise square framework, rotatably be arranged in imput shaft and driven shaft in square framework, be positioned at the external side of square box and be fixed on the driving wheel of both ends of main drive shaft, be installed on the motor in square framework, described imput shaft and driven shaft are parallel to each other and form a horizontal surface, described motor is meshed with one of them driving wheel, described driven shaft two ends one is fixed with column-shaped projection, described column-shaped projection is positioned at the external side of square box and flower wheel is installed, the axial line of the axial line of described driven shaft and two ends column-shaped projection thereof parallels and mutually not on same straight line.
Optimally, the axial line of the axial line of described driven shaft and the column-shaped projection at its two ends is in same plane and apart from equating.
Further, described distance is 0.5 ~ 2 millimeter.
Further, described imput shaft is connected with square framework by bearing with driven shaft.
Further, described column-shaped projection is connected with flower wheel by bearing assembly, and described bearing assembly is socketed to form from inside to outside successively by clutch shaft bearing, spacing sleeve, the second bearing.
Because technique scheme is used, the present invention compared with prior art has following advantages: twin beams walking dolly of the present invention, by the axial line of driven shaft and the axial line of two ends column-shaped projection is set to parallel and mutually not on same straight line, thereby overcome walking dolly in up " three the leg " phenomenon walking to occur of twin beams, avoid the situation of walking dolly unbalance stress, extend its service life.
Accompanying drawing explanation
Accompanying drawing 1 is the birds-eye view of twin beams walking dolly of the present invention;
Accompanying drawing 2 is the right elevation of twin beams walking dolly of the present invention;
Accompanying drawing 3 is the A-A cutaway view of accompanying drawing 2;
Wherein, 1, square framework; 2, imput shaft; 21, driving wheel; 3, driven shaft; 31, column-shaped projection; 32, flower wheel; 4, motor; 5, bearing; 6, bearing assembly; 61, clutch shaft bearing; 62, spacing sleeve; 63, the second bearing.
The specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiment of the invention is elaborated.
Twin beams walking dolly as shown in Figures 1 to 3, mainly comprises square framework 1, imput shaft 2, driving wheel 21, driven shaft 3, flower wheel 32, motor 4.
Wherein, imput shaft 2 and driven shaft 3 are rotatably arranged in square framework 1, and they are parallel to each other and in same level; Driving wheel 21 is fixed on the two ends of imput shaft 2 and is positioned at the outside of square framework 1; Motor 4 is installed in square framework 1 and is meshed with one of them driving wheel 21, for power is provided; Driven shaft 3 two ends one are fixed with column-shaped projection 31, and this column-shaped projection 31 is positioned at square framework 1 outside and flower wheel 32 is installed, and flower wheel 32 can rotate on column-shaped projection 31; The axial line of the axial line of driven shaft 3 and two ends column-shaped projection 31 thereof parallels but mutually not on same straight line, therefore can effectively overcome walking dolly in up " three the leg " phenomenon walking to occur of twin beams, when twin beams walking dolly is walked on beam, do not worry twin beams not steadily and cause the situation of walking dolly unbalance stress, extend its service life.
In the present embodiment, as shown in Figure 1, the axial line of the axial line of driven shaft 3 and the column-shaped projection at its two ends 31 in same plane and distance equate, their distance is preferably 0.5 ~ 2 millimeter, has avoided the excessive or asymmetric flexural deformation that causes driven shaft 3 of the axial line of driven shaft 3 and the axial line spacing of column-shaped projection 31.Imput shaft 2 is connected with square framework 1 by bearing 5 with driven shaft 3, makes them interior rotatable in square framework 1; Column-shaped projection 31 is connected with flower wheel 32 by bearing assembly 6, wherein bearing assembly 6 is socketed to form from inside to outside successively by clutch shaft bearing 61, spacing sleeve 62, the second bearing 63, the smooth running that can guarantee twin beams walking dolly, reduces friction, and saves electric energy.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and implement according to this; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
