Description
Technical field
The utility model relates to containers to store up place lifting equipment field, be to be related to one kind for collecting more specifically
The mixed wheel construction of two kinds of wheels of yard crane cart in vanning stockyard.
Background technique
General Container Yard place operation mostly uses rubber tired gantry crane (hereinafter referred to as RTG) and track gate-type to rise
Heavy-duty machine (hereinafter referred to as RMG) two ways, most of Container Yard places carry out operation using RTG.Compared with RMG, RTG makees
Industry flexibility with higher, but since RTG large vehicle walking uses rubber tyre, cause it to control difficulty ratio RMG bigger.One side
Face, in cart positioning, because being easy sideslip in cart driving process without track, there are difficulty for the confirmation of the position RTG, rise
Rubber tyre flexible deformation during rising, increases the positioning difficulty of container lockhole and tapered end, it is fast to constrain RTG remote control
The paces of speed development.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides one kind and is used for
The place cart of Container Yard mixes wheel construction.
A kind of yard crane cart for Container Yard of the utility model mixes wheel construction, passes through following technical proposals
It is achieved, bogie frame is equipped with steel wheel and is offset to the rubber tyre of steel wheel center line, and rubber tyre is mounted on
On tire dolly, the telescopic rod of tire dolly top and lifting device is fixed, and lifting device is made of fixed frame and telescopic rod two parts,
The fixed frame of lifting device is fixed by pivot pin and bogie frame, the fixed revolving support in tire dolly top, and revolving support is by inner ring, outer
Circle, rolling element three parts composition, inner ring and the telescopic rod lower part of revolving support are fixed, the outer ring of revolving support and tire dolly
Top is fixed, and tire dolly top is equipped with driving device, and driving device drives the outer ring of revolving support to realize under tire dolly
The rotation in portion.Driving device is used hydraulic or is driven by electricity.
Compared with prior art, the utility model has the beneficial effects that
By the utility model, flexibility height, the mobility that existing RTG has in the operation process of place can be comprehensively utilized
Stability good advantage when strong advantage and RMG operation, eliminates that traditional RTG shaking volume in operation process is big, positioning control
Make difficult problem.
Detailed description of the invention
Fig. 1 is the utility model structure diagram；
Fig. 2 is the structural front view of the utility model tire dolly part；
Fig. 3 is the structural side view of the utility model tire dolly part.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
As shown in Figure 1-3, a kind of place cart for Container Yard of the utility model mixes wheel construction, place cart
Bogie frame 1 is fixed at saddle beam both ends respectively, and the both ends of the bogie frame are separately connected steel wheel 2, and steel wheel is driven by motor；
The centre of bogie frame is provided with the rubber tyre 3 of the liftable and rotation that are offset to steel wheel center line, rubber tyre installation
On tire dolly 4, the telescopic rod 5 of tire dolly top and lifting device is fixed, and lifting device is by fixed frame 6 and telescopic rod 5 two
Be grouped as, the fixed frame of lifting device is fixed by pivot pin and bogie frame, the fixed revolving support in tire dolly top, revolving support by
Inner ring 7, outer ring 8,9 three parts of rolling element composition, inner ring and the telescopic rod lower part of revolving support are fixed, outside revolving support
Circle is fixed with tire dolly top, and tire dolly top is equipped with driving device, and driving device drives the outer ring of revolving support real
The rotation of existing tire dolly lower part.Driving device is used hydraulic or is driven by electricity.
Specific work process is as follows:
Realize that the mixed wheel corresponding stockyard of place crane operation needs track of mating formation, track tyre tread and existing place horizontal plane are neat
It is flat.In place when operation, big car state is that the steel wheel of bogie frame is contacted with track tyre tread, and driving large vehicle walking carries out
Positioning；When transition, driving steel wheel first drives large vehicle walking to the place end nearest from transition area；Then, rubber tyre
It synchronizes and drops to ground and locking, support complete machine (contains suspender), and steel wheel is hanging at this time, and driving rubber tyre drives big garage
It sails to steering Board position；Then after driving revolving support is rotated by 90 °, rubber tyre is travelled to working space, goes back to 0 °；Finally
Driving rubber tyre frame is promoted after traveling enters place end Lead-In Area, and steel wheel is entered the orbit, and transition operation is completed.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
