Abstract
The utility model discloses a kind of transfer crane curve motion mechanism, include walking carriage vehicle frame, the lower rotary flange matching with the upper rotary flange of hoisting crane cross sill bottom is installed on walking carriage vehicle frame, one side of walking carriage vehicle frame is provided with the large wheels that move along extra curvature track, the opposite side of walking carriage vehicle frame is provided with the little wheels that move along curve inner orbit, motor and speed reducer for driving large and small wheels to move is installed on walking carriage vehicle frame, and the both sides of walking carriage vehicle frame are separately installed with a plurality of flat gear wheels.The utility model manufacture is simple, with low cost, adaptation nonideality lower curve maneuverability is strong, safe and reliable, the needs of hoisting crane in specific environment, landforms situation lower railway curve motion mode have been met, and met camp site needs, reduced the construction cost of unit in charge of construction.
Description
Technical field
The utility model relates to transfer crane field, specifically a kind of transfer crane curve motion mechanism.
Background technology
Due to highway in China, railway, Infrastructure etc. are built development, some remote districts, Shou Shou camp site, mountain area landform, the impacts such as landforms, operation track for crane manufactures some landform of straight line pattern and cannot realize, what have may increase construction cost greatly, based on this kind of situation, track has to adopt curve mode, and for track non-rectilinear running condition, because camp site radius of curvature can not reach perfect condition, (radius of curvature variation differs to lay track foundation precision, be uneven, gauge error) lower, manufacturing errors impact, curve under out of reach perfect condition.
Utility model content
The purpose of this utility model is to provide a kind of transfer crane curve motion mechanism, meets hoisting crane at the needs of specific environment, landforms situation lower railway curve motion mode, and meets camp site needs, reduces the construction cost of unit in charge of construction.
The technical solution of the utility model is as follows:
A kind of transfer crane curve motion mechanism, include walking carriage vehicle frame, it is characterized in that: the lower rotary flange matching with the upper rotary flange of hoisting crane cross sill bottom is installed on described walking carriage vehicle frame, one side of walking carriage vehicle frame is provided with the large wheels that move along extra curvature track, the opposite side of walking carriage vehicle frame is provided with the little wheels that move along curve inner orbit, motor and speed reducer for driving described large and small wheels to move is installed on walking carriage vehicle frame, and the both sides of walking carriage vehicle frame are separately installed with a plurality of flat gear wheels.
Described transfer crane curve motion mechanism, it is characterized in that: between the upper rotary flange of described hoisting crane cross sill bottom and described lower rotary flange, by setting spindle, be connected, and be provided with tetrafluoro plate between the upper rotary flange bottom hoisting crane cross sill and described lower rotary flange.
Described transfer crane curve motion mechanism, is characterized in that: the wheels that described large and small wheels adopt respectively tread to widen.
The beneficial effects of the utility model:
The utility model manufacture is simple, with low cost, adaptation nonideality lower curve maneuverability is strong, safe and reliable, the needs of hoisting crane in specific environment, landforms situation lower railway curve motion mode have been met, and met camp site needs, reduced the construction cost of unit in charge of construction.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one side.
Fig. 2 is the structural representation of the utility model opposite side.
The specific embodiment
Referring to Fig. 1, 2, a kind of transfer crane curve motion mechanism, include walking carriage vehicle frame 1, the lower rotary flange 2 matching with the upper rotary flange of hoisting crane cross sill bottom is installed on walking carriage vehicle frame 1, one side of walking carriage vehicle frame 1 is provided with the large wheels 3 that move along extra curvature track, the opposite side of walking carriage vehicle frame 1 is provided with the steamboat group 4 moving along curve inner orbit, on walking carriage vehicle frame 1, be provided with for driving large, motor 5 and reductor that steamboat group moves, the both sides of walking carriage vehicle frame 1 are separately installed with a plurality of flat gear wheels 6, gauge while guaranteeing hoisting crane curve motion, prevent running wheel derailing, avoid undue wear road wheel wheel rim, meet hoisting crane moves in situation under curve track.
In the utility model, between the upper rotary flange of hoisting crane cross sill bottom and lower rotary flange 2, by setting spindle, be connected, and between the upper rotary flange of hoisting crane cross sill bottom and lower rotary flange 2, be provided with tetrafluoro plate, capable of reducing friction resistance, makes the rotation that chassis can be easily random; The wheels that large and small wheels 3,4 adopt respectively tread to widen, in the time of may there is wheel card rail, derailment occurring, compensate and revise when hoisting crane moves on curve track, make complete machine steadily operation smoothly in orbit.
When hoisting crane is during by rectilinear orbit arrival curve track, complete machine still keeps square constant, due between the upper rotary flange of hoisting crane cross sill bottom and lower rotary flange 2, by setting spindle, be connected, and in junction, be provided with tetrafluoro plate, so complete machine can be adjusted according to the track of curve automatically, and a plurality of flat gear wheels 6 are adjustable, when complete machine march trajectory moves, also there will not be running wheel derailing, the situations such as wearing and tearing road wheel wheel rim, due to the internal diameter of curve track and the arc length of external diameter different, if the large automobile-used same motor in bottom, reductor and running wheel, cause the running velocity of complete machine consistent, long outer short situation in the distance of walking occurs, will cause the operation of complete machine parallelogram, for avoiding occurring this situation, the utility model curve motion device adopts same motor, the running wheel of reductor and two kinds of different-diameters, thereby reach the consistent of running velocity.
The utility model practicality has met hoisting crane in specific environment, landforms situation in sum, and the needs of orbital curve operation scheme, and met camp site needs are a kind of easy reliable, easy and simple to handle, new structures cheaply.
