Abstract
The embodiment of the invention discloses a main amplitude mast of a crawler crane and belongs to the technical field of the crawler crane. The main amplitude mast of the crawler crane is arranged on a crawler crane platform. The main amplitude mast consists of an upper part module (1) and a lower part module (2). The upper part module (1) and the lower part module are connected together through a joint (3). The invention also discloses the crane. The crane comprises the main amplitude mast provided by the invention. According to the main amplitude mast of the crawler crane, through dividing the main amplitude mast into the two modules connected through the joint, not only be the length requirement of transportation met but also the optimal design requirement of the main amplitude mast can be met.
Description
Technical field
The present invention 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.
Summary of the invention
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 embodiment of the invention provides a kind of crawler crane main amplitude mast.Said technical scheme is following:
The embodiment of the invention 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 present invention 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 embodiment of the invention 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.
Description of drawings
In order to be illustrated more clearly in the technical scheme in the embodiment of the invention; The accompanying drawing of required use is done to introduce simply in will describing embodiment below; Obviously, the accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

The specific embodiment
For making the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing that embodiment of the present invention is done to describe in detail further below.
Shown in Fig. 2 (a) and Fig. 2 (b); The embodiment of the invention 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 main amplitude mast of the present invention 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 main amplitude mast provided by the invention, 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 embodiment of the invention 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 preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
