Abstract
The embodiment of the utility model discloses a main amplitude-variance mast of a crawler crane, belonging to the technical field of crawler cranes. The main amplitude-variance mast is arranged on a crawler crane platform and comprises an upper module (1) and a lower module (2) which are connected together through a joint (3). The utility model also discloses the crane which comprises the main amplitude-variance mast. As the main amplitude-variance mast is divided into the two modules which are connected with each other by the joint, the length requirement of transportation is satisfied, and the optimal design requirement of the main amplitude-variance mast can also be satisfied.
Description
Technical field
The utility model relates to the crawler crane technical field, particularly a kind of crawler crane main amplitude mast and comprise the hoisting crane of this mast.
Background technology
At present, the main amplitude mast 11 that crawler crane is used is arranged at crawler crane platform 12, referring to Fig. 1, is the important component part of hoisting crane.For the large-tonnage crawler crane, because the requirement that jib plays the arm requirement and hangs hoisting moment when carrying, the length of main amplitude mast and weight all can significantly increase, and particularly length can exceed the length requirement in the transportation request usually.If, reduce the length dimension of main amplitude mast in order to satisfy requirements on transport, at this moment often can not satisfy an arm requirement of long principal arm again, can not reach optimum strained condition.
The utility model content
Can not satisfy length requirement and the limited problem of scantling of structure in the transportation in order to solve the prior art main amplitude mast, the utility model embodiment provides a kind of crawler crane main amplitude mast.Said technical scheme is following:
The utility model embodiment provides a kind of main amplitude mast that is used for crawler crane; Said main amplitude mast; Be arranged at the crawler crane platform; Wherein, said main amplitude mast is made up of upper module and lower module two parts, and said upper module and said lower module link together through joint.
Preferably, said joint connects through bearing pin.
Concrete, said main amplitude mast bottom is provided with the twisted point hole, and the top is equipped with support.
Preferably, the end that said upper module is relative with said joint is provided with luffing assembly pulley and leading sheave group.
Preferably, be provided with telescopic rod between said lower module end relative and the host platform with said joint.
Concrete, said luffing assembly pulley and leading sheave group are hinged on the said support through bearing pin.
The utility model also provides a kind of hoisting crane, and this hoisting crane has comprised above-mentioned main amplitude mast.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is: through main amplitude mast being divided into joint bonded assembly two parts module, not only satisfied the length requirement of transportation, also can satisfy the optimum designing requirement of main amplitude mast.

The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer, will combine accompanying drawing that the utility model embodiment is done to describe in detail further below.
Shown in Fig. 2 (a) and Fig. 2 (b); The utility model embodiment provides a kind of main amplitude mast that is used for crawler crane; This main amplitude mast is arranged at the crawler crane platform, wherein; Main amplitude mast is made up of upper module 1 and lower module 2 two parts, and upper module 1 links together through joint 3 with lower module 2.Preferably, joint connects through bearing pin.Shown in Fig. 3 (a) and Fig. 3 (b), in when transportation joint 3 to be taken apart, upper module transports with platform, and lower module 2 is transported with hoisting mechanism, can satisfy transportation request easily, has practiced thrift traffic cost.
Simultaneously, the main amplitude mast bottom is provided with twisted point hole 10, is hingedly mounted on host platform, and the top is provided with support 9.Be provided with luffing assembly pulley 4 and leading sheave group 5 at upper module 1 end relative with joint.Luffing assembly pulley 4 connects luffing steel rope 6, and two of luffing steel rope 6 is connected with the luffing elevator at last in the same way.Leading sheave group 5 connects hoist rope 7, and an end of hoist rope 7 connects lifting elevator, an end connecting shackle.Be provided with telescopic rod 8 between end that lower module 2 and joint are relative and the host platform, telescopic rod 8 is with main amplitude mast motion telescopic variation.Wherein, luffing assembly pulley 4 is hingedly mounted on the support 9 through bearing pin with leading sheave group 5.
As shown in Figure 4, when the crawler crane mode of operation, through bearing pin upper module 1 and lower module 2 being assembled together forms a whole, and has satisfied the work operating needs.It should be noted that to be connected between two modules of the utility model main amplitude mast to be rigidly connected that the bearing pin that is not limited to present embodiment connects, arbitrary satisfactory connection all meets the demands.
The invention also discloses a kind of hoisting crane, this hoisting crane comprises the main amplitude mast that the utility model provides, and those skilled in the art can understand the structure of other parts except that above-mentioned main amplitude mast in this hoisting crane, do not repeat them here.
The main amplitude mast of the utility model embodiment splits into two modules through modular design, utilizes bearing pin conveniently to link together again; Can not receive the restriction of transportation request; Can design optimum structure, satisfy long principal arm and played the arm requirement, and carry a state bigger hoisting moment is provided hanging; The main amplitude mast structure is strengthened, and the rigidity reliability is further promoted.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
