Abstract
The utility model relates to the front and back vehicle turntable linking device for a crawler crane; the crawler crane comprises a front vehicle and a back vehicle, wherein independent walking mechanisms are arranged on the front vehicle and the back vehicle; a front vehicle turntable is arranged on the front vehicle; a back vehicle turntable is arranged on the back vehicle; and the front and back vehicle turntable linking device further comprises a connecting beam for connecting the front vehicle turntable and the back vehicle turntable. According to the utility model, through the adoption of the connecting beam, the connection between the front and back vehicles of the crawler crane is achieved; through the walking of the front vehicle and the back vehicle, the walking and rotation of the whole crane is finished, so that the walking and rotating actions of the front vehicle and the back vehicle can be synchronous; and according to the utility model, the stability of the whole crane is also guaranteed; moreover, as independent rotating mechanisms are not needed by the front vehicle and the back vehicle, the manufacturing cost is effectively saved.
Description
Technical field
The utility model relates to a kind of mechanical connection mechanism and hoisting crane, particularly relates to a kind of front and back car turntable linkage and crawler crane for crawler crane.
Background technology
Crawler crane is the truss-type cantilever crane structure hoisting crane that adopts caterpillar band traveling chassis.Current, along with the hoisting capacity of crawler crane constantly increases, the crawler crane of traditional bicycle form can not satisfy the designing requirement of present engineering, so, just produced two car formula crawler cranes.
Two car formula crawler cranes mainly comprise front truck and two parts of rear car, and forward and backward car all contains turntable, and turntable is the stage apparatus of placing power system, power hydraulic system on the crawler crane.The important component part that front truck turntable and rear car turntable also are super-tonnage crawler cranes, forward and backward car turntable also all is main primary structure member, and connects each other between the forward and backward car.
The utility model content
The purpose of this utility model be propose a kind of simple in structure, be easy to realize, need not swing type mechanism independently, the front and back car turntable linkage and the crawler crane that are used for crawler crane that cost is lower.
For achieving the above object, the utility model provides a kind of front and back car turntable linkage for crawler crane, described crawler crane comprises front truck, rear car, shown in be equipped with independently traveling gear on front truck and the rear car, described front truck is provided with the front truck turntable, described rear car is provided with rear car turntable, and described front and back car turntable linkage also comprises the tie-beam that connects described front truck turntable and rear car turntable.
Preferably, described tie-beam is metal framework structure.
More preferably, during described front truck revolution, described rear car is walked around front truck by tie-beam.
Preferably, during described rear car revolution, described front truck is walked around rear garage by tie-beam.
Preferably, during described crawler crane revolution, described front car and rear car is walked around the other side respectively by tie-beam.
Another purpose of the present utility model is to provide a kind of crawler crane, and this crawler crane comprises above-mentioned front and back car turntable linkage.
Based on technique scheme, the utility model has the advantages that:
The utility model has been realized connection between the forward and backward car of crawler crane by tie-beam, and finish walking and the revolution of car load by the walking of front truck and rear car, making front truck and rear garage walk and turn round action can realize synchronously, the utility model has also guaranteed the stability of car load, and the front and back car all need not independently swing type mechanism, effectively saved manufacturing cost.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, consists of the application's a part, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is use view of the present utility model.
The specific embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Referring to Fig. 1 and Fig. 2, the preferred embodiment of a kind of front and back car turntable linkage for crawler crane of the utility model shown in it, described crawler crane comprises front truck 1, rear car 2, shown in be equipped with independently traveling gear on front truck 1 and the rear car 2, as depicted in figs. 1 and 2; Wherein, described front truck 1 is provided with front truck turntable 3, and described rear car 2 is provided with rear car turntable 4, and described front and back car turntable linkage also comprises the tie-beam 5 that connects described front truck turntable 3 and rear car turntable 4, preferably, tie-beam 5 described in the utility model is metal framework structure.
Forward and backward car of the present utility model all need not independently swing type mechanism (before and after the existing crawler crane on the car, be equipped with independently swing type mechanism, its weight is larger, and cost is higher), when front truck 1 revolution of the present utility model, described rear car 2 is walked around front truck 1 by tie-beam 5.
And when rear car 2 revolution of the present utility model, described front truck 1 is walked around rear car 2 by tie-beam 5.
Further, when the complete machine of described crawler crane need to turn round, then can walk around the other side respectively by tie-beam 5 for front truck 1 and rear car 2, thereby realize the car load rotation.
Another purpose of the present utility model is to provide a kind of crawler crane, this crawler crane has comprised above-mentioned front and back car turntable linkage, certainly, this crawler crane need not swing type mechanism is being set, and traveling gear gets final product and only need to be provided with separately on the front car and rear car independently.
Should be noted that at last: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
