Abstract
The utility model discloses a steel wire rope torsion-proof tail section for a tower crane. The steel wire rope torsion-proof tail section for tower crane comprises a tail section frame and a torsion-proof device, wherein the end portion of a tail section frame comprises a cross bar, and the torsion-proof device is fixedly connected with the cross bar. The steel wire rope torsion-proof tail section for the tower crane has the advantages that the torsion-proof device can rapidly release a stress of a steel wire rope, and thus the service life of the steel wire rope can be prolonged and the degree of reliability of the tower crane can be improved.
Description
Technical field
The utility model relates to a kind of anti-minor details of turning round, more precisely the anti-minor details of turning round of a kind of steel rope for tower crane.
Background technology
Tower crane uses the steel rope hoisting heavy when work, but on the crane arm minor details of tower crane of the prior art anti-twisting equipment is not set, steel rope in use, there is larger stress to discharge, steel rope is easily by this stress damage, affect the reliability of hoisting crane, the life-span of steel rope is also shorter simultaneously.
The utility model content
The utility model mainly is to solve the existing technical matters of prior art, thereby provide a kind of with anti-twisting equipment, can discharge fast the stress in the steel rope, can prolong the life-span of steel rope, improve the anti-minor details of turning round of the steel rope that is used for tower crane of the fiduciary level of hoisting crane.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
A kind of steel rope for tower crane is anti-turns round minor details, comprises a minor details framework, and the end of described minor details framework comprises a cross bar, describedly anti-ly turns round minor details and also comprises an anti-twisting equipment, and described anti-twisting equipment is captiveed joint with described cross bar.
As the utility model preferred embodiment, described anti-twisting equipment comprises that one connects channel-section steel and an anti-wheel of turning round, and the described anti-wheel of turning round is rotationally connected with the described channel-section steel that is connected, and described connection channel-section steel and described cross bar are welded to connect.
As the utility model preferred embodiment, the described anti-wheel of turning round comprises a shaft clevis, a roller and a bearing, and described roller and described shaft clevis are rotationally connected, and described shaft clevis is rotationally connected with the described channel-section steel that is connected by described bearing.
Therefore the anti-advantage of turning round minor details of the steel rope for tower crane of the present utility model is, with anti-twisting equipment, can discharge fast the stress in the steel rope, can prolong the life-span of steel rope, improves the fiduciary level of hoisting crane.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Wherein:
1, minor details framework; 11, cross bar;
2, anti-twisting equipment; 21, connect channel-section steel; 22, the anti-wheel of turning round;
221, shaft clevis; 222, roller; 223, bearing.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
It is a kind of with anti-twisting equipment that the utility model provides, and can discharge fast the stress in the steel rope, can prolong the life-span of steel rope, improves the anti-minor details of turning round of the steel rope that is used for tower crane of the fiduciary level of hoisting crane.
As shown in Figure 1 and Figure 2, a kind of steel rope for tower crane is anti-turns round minor details, comprises a minor details framework 1, and the end of this minor details framework 1 comprises a cross bar 11, and this prevents that turning round minor details also comprises an anti-twisting equipment 2, and this anti-twisting equipment 2 is captiveed joint with this cross bar 11.
Such as Fig. 2, shown in Figure 3, this anti-twisting equipment 2 comprises that one connects channel-section steel 21 and an anti-wheel 22 of turning round, and this is anti-turns round wheel 22 and be connected channel-section steel 21 with this and be rotationally connected, and this connection channel-section steel 21 and this cross bar 11 are welded to connect.
Such as Fig. 2, shown in Figure 4, this anti-wheel 22 of turning round comprises a shaft clevis 221, a roller 222 and a bearing 223, and this roller 222 is rotationally connected with this shaft clevis 221, and this shaft clevis 221 is connected channel-section steel 21 by this bearing 223 and is rotationally connected with this.
Below only with an embodiment mentality of designing of the present utility model is described, in the situation that system allows, the utility model can expand to simultaneously external more functional module, thereby expands to greatest extent its function.
The above only be the specific embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
