Description

A kind of novel tire type gantry container crane rotates big mechanism of car
Technical field
The present invention relates to engineering machinery field, specifically, it is related to a kind of rubbertyred container gantry crane and its big Car and lifting-up steering gear.
Background technology
Rubbertyred container gantry crane (RTG) is that one kind carries out container handling for Container Yard and pile is made The special equipment of industry.Stockyard typically sets multiple fields position, it is necessary to many fields of RTG position in the case of the configuration RTG number of units deficiencies Between carry out transition work., it is necessary to the wheel of cart walking mechanism carries out go to action during transition, in go to action During huge frictional force can be produced between tire and ground, huge abrasion can be caused to tire.Due to tire and ground Between friction it is huge, cause steering mechanism to need unusual steering force.The big height of current RTG designs is very high, phase The center of gravity answered is also very high, causes crank, and construction weight is big.Big vehicle steering mechanism and lifting body are extremely complex at present, It is with high costs.
The content of the invention
In order to overcome the defect and deficiency of existing mechanism, it is an object of the invention to provide a kind of gantry container crane The compact simple cart walking mechanism of steering structure.This big mechanism of car design is easy, and compact conformation, part is few.
The big mechanism of car of rotation of the invention, including.
Bogie frame, including wheel group, the equalizer bar vehicle frame for supporting wheel.
Jacking apparatus, are a kind of push rods, this push rod can be it is electronic can also be hydraulic pressure.Jacking apparatus play handle Whole machine jack-up leaves the function on ground come the wheel that makes bogie frame.
Device for revolving and driving, this device is integrally purchased, and can drive bogie frame based on revolving support around central rotation To the angle of need of work.Because jacking apparatus are whole machine jack-up, revolution frictional force becomes very small, can be with minimum promotion Power just can rotate bogie frame, reduce revolution driving power.This device for revolving and driving is integrally purchased, and with self-locking work( Can, locating detent is eliminated, the slew gear arrangement form of current complexity can be avoided.
Semiaxis, is the vital part for connecting bogie frame and whole machine portal frame, is in working order bogie frame to portal frame Support part.The form of semiaxis is designed to, is, in order to avoid the locus of jacking apparatus, to make the jacking apparatus maintenance position can be with Rise in portal frame space, maintain easily.
Preferably, jacking apparatus are electric pushrod.
Preferably, jacking apparatus are hydraulic cylinder.
Preferably, device for revolving and driving is the device for revolving and driving of integral form.
Preferably, device for revolving and driving is slewing bearing and drive mechanism separate form.
Brief description of the drawings
Fig. 1 is a kind of tool that a kind of novel tire type gantry container crane provided by the present invention rotates big mechanism of car The schematic diagram of body implementation method.
Wherein, the corresponding relation in Fig. 1 between reference and component names is.
1. jacking apparatus;2. semiaxis;3. device for revolving and driving;4. bogie frame
Specific embodiment.
Core purport of the invention rotates big mechanism of car, cart to provide a kind of novel tire type gantry container crane Bogie frame compact conformation in mechanism, device for revolving and driving power is small, compact conformation, and the built-in saving space of jacking apparatus, semiaxis sets Meter facilitates the maintenance of jacking apparatus.Sleeve mechanism compact conformation, lightweight, low cost, parts are few, and simple structure is easily realized.
Without loss of generality, it is introduced as a example by the application of rubbertyred container gantry crane by big mechanism of car herein, It will be understood by those skilled in the art that being also not excluded for application of the big mechanism of car provided in this article in Other Engineering machinery.
In order that those skilled in the art is better understood from technical scheme, below in conjunction with the accompanying drawings with example pair The present invention is described in further detail.
Fig. 1 is refer to, Fig. 1 is a kind of novel tire type gantry container crane rotation cart provided by the present invention A kind of schematic diagram of specific embodiment.
When whole machine transition is needed, jacking apparatus 1 work, and whole machine jack-up, the wheel of bogie frame 4 is left ground, this When, device for revolving and driving 3 works, and drives bogie frame 4 to go to the operating angle of needs, after going to the angle of needs, jacking apparatus 1 Withdraw, fall to the ground bogie frame 4, whole machine portal frame is supported by semiaxis 2, received in the continuation of jacking apparatus 1, make to be connect with ground After tactile steel plate leaves ground certain altitude, jacking apparatus 1 are stopped.
Two semiaxis designs are, in order to avoid jacking apparatus, space to be got out of the way to jacking apparatus.
Bogie frame integral-rotation is, in order to save revolving support, and to make to be reduced friction after departing between wheel and ground.
Revolving support has auto-lock function.
A kind of novel tire type gantry container crane rotation cart provided by the present invention has been carried out in detail above Introduce.Apply specific case herein to be set forth principle of the invention and specific implementation, the explanation of above example is only It is to be used to help understand the method for the present invention and core concept.It should be pointed out that it will be apparent to those skilled in the art that not departing from On the premise of the principle of the invention, some improvement and modification can also be carried out to the present invention, these are improved and modification also falls into this hair In bright scope of the claims.
