Abstract
The invention discloses a novel rubber-tyred container gantry crane rotation cart mechanism. The mechanism comprises a jacking device 1 which jacks up a main machine gantry, the gantry is connected with a bogie frame 4 by virtue of half shafts 2, and the upper side of the bogie frame is provided with a swing drive device 3 used for driving the whole bogie frame to integrally rotate. The swing drive device has a self-locking function, the space is reserved for the jacking device by virtue of the two haft shaft designs, and the jacking device is conveniently arranged at the interior, so that the overall outer width size of a cart is further reduced; the maintaining part of the jacking device 1 is risen to the gantry part, so that the installation and maintenance of the jacking device are convenient.
Description
Technical field
The present invention relates to engineering machinery field, specifically, relate to a kind of rubbertyred container gantry crane and cart thereof and lifting-up steering gear.
Background technology
Rubbertyred container gantry crane (RTG) is a kind of specialized equipment carrying out container handling and stacking operation for container depot.Stockyard generally arranges multiple positions, when configuring RTG number of units deficiency, needs to carry out transition work between position, RTG many fields.In the process of transition, need the wheel of cart walking mechanism to carry out handling maneuver, in the process of handling maneuver, huge friction force can be produced between tire and ground, huge wearing and tearing can be caused to tire.Because the friction between tire and ground is huge, cause steering hardware needs steering effort very.The large height of current RTG design is very high, and corresponding center of gravity is also very high, and cause crank, structural weight is large.At present large vehicle steering mechanism and lifting body very complicated, with high costs.
Summary of the invention
In order to overcome defect and the deficiency of existing mechanism, the object of the present invention is to provide a kind of simple cart walking mechanism of compact steering structure of gantry container crane.This cart mechanism design is easy, and compact conformation, part is few.
The large mechanism of car of rotation of the present invention, comprises.
Bogie frame, comprises wheel group, equalizing bar vehicle frame for support wheel.
Jacking apparatus is a kind of push rod, and namely this push rod can be electronic also can be hydraulic pressure.Jacking apparatus plays complete machine jack-up to the function making the wheel of bogie frame leave ground.
Device for revolving and driving, the buying of this device entirety, can drive table vehicle frame based on revolving support around the angle of central rotation to need of work.Because jacking apparatus is complete machine jack-up, revolution friction force becomes very little, bogie frame just can be able to be made to rotate with minimum propelling thrust, reduces revolution driving power.This device for revolving and driving entirety buying, and there is auto-lock function, eliminate locating detent, swing type mechanism arrangement form complicated at present can be avoided.
Semiaxis is the vital part of connected unit vehicle frame and complete machine portal frame, is the support part of bogie frame to portal frame in working order.Being designed to the form of semiaxis, is the locus in order to dodge jacking apparatus, jacking apparatus maintenance position can be risen in portal frame space, maintain easily.
Preferably, jacking apparatus is electric pushrod.
Preferably, jacking apparatus is hydraulic actuating 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 driver train separate form.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that a kind of Novel tire type container gantry crane provided by the present invention rotates a kind of detailed description of the invention of large mechanism of car.
Wherein, the corresponding relation in Fig. 1 between Reference numeral and component names is.
1. jacking apparatus; 2. semiaxis; 3. device for revolving and driving; 4. bogie frame
detailed description of the invention.
Core purport of the present invention rotates large mechanism of car to provide a kind of Novel tire type container gantry crane, bogie frame compact conformation in large mechanism of car, device for revolving and driving power is little, compact conformation, the built-in conserve space of jacking apparatus, semiaxis design facilitates the maintenance of jacking apparatus.Sleeve mechanism compact conformation, lightweight, cost is low, and parts are few, and structure is simple and easy to realize.
Without loss of generality, be introduced with the example that is applied as of large mechanism of car at rubbertyred container gantry crane herein, it will be understood by those skilled in the art that and also do not get rid of the application of large mechanism of car provided in this article in Other Engineering machinery.
In order to make those skilled in the art better understand technical scheme of the present invention, below in conjunction with accompanying drawing and example, the present invention is described in further detail.
Please refer to Fig. 1, Fig. 1 is the schematic diagram that a kind of Novel tire type container gantry crane provided by the present invention rotates a kind of detailed description of the invention of cart.
When the transition of needs complete machine, jacking apparatus 1 works, complete machine jack-up, make the wheel of bogie frame 4 leave ground, now, device for revolving and driving 3 works, bogie frame 4 is driven to forward the operating angle of needs to, after forwarding the angle of needs to, jacking apparatus 1 is regained, and bogie frame 4 is fallen to the ground, complete machine portal frame is supported by semiaxis 2, jacking apparatus 1 continues upper receipts, and after making to leave ground certain altitude with the steel plate of earth surface, jacking apparatus 1 quits work.
Two semiaxis designs are to avoid jacking apparatus, get out of the way space to jacking apparatus.
Bogie frame integral-rotation is to save revolving support, and makes to reduce friction after disengaging between wheel and ground.
Revolving support has auto-lock function.
Rotate cart to a kind of Novel tire type container gantry crane provided by the present invention to be above described in detail.Apply specific case herein to set forth principle of the present invention and concrete enforcement, the explanation of above embodiment just understands method of the present invention and core concept for helping.It should be pointed out that to one skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improve and modify and also fall in the protection domain of the claims in the present invention.
Claims (3)
1. a Novel tire type container gantry crane rotates large mechanism of car, comprising jacking apparatus 1 withstands on main frame portal frame, connected by semiaxis 2 between portal frame and bogie frame 4, device for revolving and driving 3 is had to drive a whole set of bogie frame integral-rotation above bogie frame, device for revolving and driving has auto-lock function, two semiaxis designs are to abdicate space to jacking apparatus, jacking apparatus is facilitated to be arranged on the middle outer wide size of entirety reducing cart further, also make the maintenance position of jacking apparatus 1 rise to portal frame part, facilitate the installation and maintenance of jacking apparatus.
