Abstract
The invention relates to a construction machinery, in particular to a flexible attachment of a tower crane. The flexible attachment of the tower crane comprises a tower body and is characterized in that a ring beam is arranged out of the tower body; four corners of the ring beam 1 are respectively provided with cantilever arms which extend outwards; upper and lower adjacent cantilever arms are crossly connected by a flexible drawing piece II; the cantilever arms on the same vertical direction are successively connected by a flexible drawing piece III; the upper end of the flexible drawing piece III is connected with the flexible drawing piece I; the lower end is connected and arranged on a tension device 8 on the ground; the upper end of the flexible drawing piece I1 and the upper end of the flexible drawing piece II are connected to the tower body; and the cantilever arms on the same horizontal plane are successively connected by a flexible connecting piece IV and a flexible connecting piece V. The invention has the beneficial effects that the scheme has simple structure and convenient construction and can satisfy the requirement of independent attachment by separating from wall dependence when the tower crane exceeds independent height.
Description
Technical field
What the present invention relates to is a kind of vehicle for construction, in particular a kind of Upon Flexible Adhesion of tower crane.
Background technology
Constantly intensive along with skyscraper adheres to tower crane and uses more and more widely, when the aspect ratio of tower machine is higher; Must rely on attachment to bear moment of torsion and bending load, guarantee intensity, rigidity and the stability of body of the tower, general tower machine need be attached on the very strong building of rigidity; Yet do not have the condition of adhering under some occasion; When for example building electricity and building cooling tower, the tower wall is very thin, can not make the tower machine attached to it.
Summary of the invention
The present invention provides a kind of Upon Flexible Adhesion that can when not having the rigid attachment body, guarantee the normal tower crane that uses of tower machine in order to remedy the limitation of prior art.
The present invention realizes through following technical scheme:
A kind of Upon Flexible Adhesion of tower crane; Comprise body of the tower, it is characterized in that: said body of the tower is provided with ring beam outward, and four angles of ring beam are respectively equipped with the cantilever beam of outside stretching, extension; Intersect neighbouring cantilever beam continuous with flexible draw piece II; The far-end of the cantilever beam on the same vertical direction links to each other with flexible draw piece III successively, and the upper end of flexible draw piece III links to each other with flexible draw piece I, and the lower end is connected and is arranged on the ground tightening device; Terminate on the body of the tower on the flexible draw piece I, the cantilever beam of same horizontal surface links to each other with flexible connecting member V with flexible connecting member IV successively.
The flexible draw piece that the present invention links to each other through intersection reduces the influence of moment of torsion to the tower machine, and the flexible draw piece that is provided with through vertical direction reduces the influence of moment of flexure to the tower machine, thus the normal operation of assurance tower machine.
In order to reduce horizontal surface side force that cantilever beam receives, the far-end of cantilever beam is fixed on two adjacent angles of ring beam through flexible draw piece IV to its stable influence.
According to the structure needs, cantilever beam can be four or eight.
Beneficial effect of the present invention: this scenario-frame is simple, and easy construction can be satisfied the requirement that can break away from the building dependence when tower crane surpasses unattached height and independently adhere to.

The specific embodiment
Below in conjunction with embodiment the present invention is done further explanation, following each embodiment only is used to explain technical scheme of the present invention, but to not restriction of the present invention,
The present invention links to each other the end portions cross of cantilever beam 5 through flexible draw piece II2; Moment of torsion from the body of the tower upper end passes to the earth through draw piece 2 like this, thereby has guaranteed the torsional stiffness of body of the tower, satisfies the requirement that breaks away from the wall dependence and independently adhere to; The moment of flexure and the moment of torsion that utilize the pulling force balance body of the tower 6 of flexible draw piece I1 and flexible draw piece II2 to receive; Improved intensity, rigidity and the stability of body of the tower 6, this scenario-frame is simple, easy construction; Can satisfy the requirement that can break away from the wall dependence when tower crane surpasses unattached height and independently adhere to, adhere to thereby derive a kind of later-model tower machine.
Accompanying drawing 4 another embodiment of the invention; Arrange cantilever beam when cantilever beam 5 adopts the mode of Fig. 4,5, two cantilever beams 5 of two cantilever beams that are provided with respectively on 4 jiaos of ring beams are the distribution that meets at right angles; Shown in (Fig. 5, Fig. 6); The flexible draw piece II2 intersection of neighbouring cantilever beam 5 usefulness is linked to each other, and the far-end of the cantilever beam 5 on the same vertical direction links to each other with flexible draw piece III3 successively, and the upper end of flexible draw piece III3 links to each other with flexible draw piece I1; The lower end is connected and is arranged on the ground tightening device 8; Terminate on the body of the tower 6 on the flexible draw piece I1, the cantilever beam 5 usefulness flexible connecting member IV7 of same horizontal surface link to each other with flexible connecting member V9 successively, and said flexible draw piece I1, flexible draw piece II2, flexible draw piece III3, flexible connecting member IV7 and flexible connecting member V9 are steel rope.
