Heavy-duty double-track crane travel mechanism support meanss.
Background technology
In recent years, with the high speed development of domestic shipbuilding industry, build large ship or maritime platform demand is more and more, sea
Foreign engineer equipment also progressively to deep water, maximizes, multifunction direction is developed.At present, the ultra-large type for carrying running mechanism rises
The mobile propulsion system of heavy-duty machine is mainly made up of operation supporting arrangement and gear rack actuating device, and this operation support meanss are led to
Cross roller vehicle to realize, ground bearing requirements are met in the form of similar uniform load the characteristics of roller vehicle.
The problem of prior art is present is mainly the guidance quality control of walking, multigroup because roller vehicle has certain width
String is when moving together, with the force of rolling friction on ground can not synchronously overcome, the component of different directions, each group roller will be produced
Car will produce the trend towards different directions deflection, and the deviation trend synthesis of all roller vehicles can cause whole rigid leg or soft again
Property leg the direction of motion change, and the pedestal of concrete structure whether can about beam deflection and bear thus produce extruding and
Friction can not be assessed, and this roller vehicle either purchases imported product or oneself processing and manufacturing, can not all avoid cost
The problem of costliness, difficult maintenance.
Utility model content
The purpose of this utility model is a kind of heavy-duty double-track crane travel mechanism designed for prior art deficiency
Support meanss, the supporting construction connected using hinged-support, crane can rotate into the automatic tune of row in movement so that direction along ng a path is micro-
It is whole, by crane from heavy load and lift heavy load it is relatively uniform, be smoothly delivered to track foundation, it is ensured that wheel compressive load it is in-orbit
Evenly distribute, preferably solve the guidance quality control problem of ultra-large type crane walking, with large carrying capacity, operation is flat
Surely, have a safety feature, simple in construction, manufacturing cost is low, the advantages of installing and be easy to maintenance.
What the purpose of this utility model was realized in：A kind of heavy-duty double-track crane travel mechanism support meanss, including
The gantry crane being made up of girder and rigid leg and flexible leg, gantry crane is by the platform that is arranged on rigid leg and flexible leg
Car operation is in orbit, is characterized in that the rigid leg and flexible leg of gantry crane are arranged on platform by some groups of operation support meanss
Che Shang, operation support meanss are hinged with rigid leg, flexible leg and chassis respectively by upper and lower hinged-support, the operation support meanss
Set by big equalizer bar with two small equalizer bars with simple beam structure, big equalizer bar is hinged by hinge with small equalizer bar；The upper hinge
Bearing is arranged on big equalizer bar and is fixedly connected respectively with rigid leg, flexible leg and big equalizer bar；The lower hinge support is set
It is fixedly connected on chassis and respectively with small equalizer bar and chassis.
The axis hole of long waist shaped is provided with the small equalizer bar.
The utility model has Self-balancing compared with prior art, can be along crane runway and perpendicular to lifting
Machine track both direction is automatically adjusted, it is ensured that wheel load uniform load is distributed, and can be by configuring the operation machine of varying number
Structure support meanss, to adapt to the ultra-large type gantry crane demand of different technologies parameter, large carrying capacity can carry 1000t
Vertical load, operates steadily, simple in construction, and manufacturing cost is low, the advantages of installing and be easy to maintenance.

Embodiment
Refering to accompanying drawing 1, the utility model includes the gantry crane being made up of girder 1 and rigid leg 2 and flexible leg 3, door
Formula crane is arranged on chassis 11 by some groups of operation support meanss 5 being arranged on rigid leg 2 and flexible leg 3, and gate-type rises
Heavy-duty machine is run by chassis 11 on track 4.The operation support meanss 5 are set by big equalizer bar 7 with two small equalizer bars 9 with simply supported beam
The self-balance structure put, big equalizer bar 7 is connected with small equalizer bar 9 using bearing pin 8, small equalizer bar 9, chassis 11 and lower hinge support 10
A part is assembled into, middle heart septum 2m is arranged on two spacing 1.5m parallel orbit 4, and is assembled into big equalizer bar 7
The operation support meanss 5 of 1000t vertical load travelling mechanisms can be carried to be a set of, and pass through the firm of upper hinge support 6 and top
Property leg 2 and the structure of flexible leg 3 connection.
When gantry crane is moved, if track 4 is along crane traffic direction out-of-flatness, each part can be around upper hinged
The hinge of seat 6 and lower hinge support 10 is automatically adjusted for micro- turn along the direction of track 4；If two tracks 4 of crane homonymy have
There is difference of height, to cause big equalizer bar 7 and bearing pin 8 not to produce extra stress, the axis hole 12 on small equalizer bar 9 is processed as length
Kidney-shaped, the constraint of release herein so that the assembly parts of small equalizer bar 9, chassis 11 and lower hinge support 10 are perpendicular to the direction of track 4
It is automatically adjusted, is adjusted by the fine motion along the direction of track 4 and perpendicular to the direction of track 4, it is ensured that wheel load uniform load point
Match somebody with somebody.
