Abstract

The invention discloses a slewing support with a double slewing structure for a tower crane. The slewing support comprises a lower support, an upper support and a slewing gear. The slewing gear is fixedly connected with the lower support, and the slewing gear is rotatably connected with the upper support. The upper support comprises two decelerator installation blocks. The slewing support comprises two decelerators and two driving motors. The decelerators are connected with the decelerator installation blocks. The driving motors are connected with the decelerators. The slewing support with the double slewing structure for the tower crane disclosed by the invention has the following advantage: with two driving motors and two decelerators, the crane can still work normally if one driving motor or reducer is damaged, and an individual driving motor and decelerator have small volume.

Description

The revolution with double back rotation structure for tower crane is supported

 

Technical field

The present invention relates to a kind of revolution and support, more precisely a kind of revolution with double back rotation structure for tower crane is supported.

 

Background technology

Tower crane comprises that a revolution support is for adjusting the orientation of crane arm, but revolution of the prior art only has a drive motor and reductor in supporting, reliability is lower, revolution support in higher position, if drive motor or reductor damage, replacement cost is high, and the size of single electric motor is larger simultaneously, takies larger space.

Summary of the invention

The present invention solves the existing technical matters of prior art, thereby provide a kind of with two drive motor and dual reducer, after drive motor or retarder damage, hoisting crane still can work, and the revolution with double back rotation structure for tower crane that the volume of single drive motor and retarder is also less is simultaneously supported.

Above-mentioned technical matters of the present invention is mainly solved by following technical proposals:

A kind of revolution with double back rotation structure for tower crane is supported, comprise undersetting, upper bracket and single-revolution gear, described swiveling gear is fixedly connected with described undersetting, described swiveling gear and described upper bracket are rotationally connected, described upper bracket comprises two retarder mounting blocks, described revolution is supported and is comprised two retarders and two drive motor, and described retarder is connected with described retarder mounting blocks, and described drive motor is connected with described retarder.

As preferred embodiment of the present invention, the lower end of described retarder is provided with a driven wheel, and described driven wheel and described swiveling gear are connected with a joggle.

The advantage that the revolution with double back rotation structure for tower crane therefore of the present invention is supported is, with two drive motor and dual reducer, after drive motor or retarder damage, hoisting crane still can work, and the volume of single drive motor and retarder is also less simultaneously.

 

Accompanying drawing explanation

In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the perspective view that the revolution with double back rotation structure for tower crane of the present invention is supported;

Wherein:

1, undersetting;

2, upper bracket; 21, retarder mounting blocks;

3, swiveling gear;

4, retarder; 41, driven wheel;

5, drive motor.

 

The specific embodiment

Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention are made to more explicit defining.

The invention provides a kind of with two drive motor and dual reducer, after drive motor or retarder damage, hoisting crane still can work, and the revolution with double back rotation structure for tower crane that the volume of single drive motor and retarder is also less is simultaneously supported.

As shown in Figure 1, a kind of revolution with double back rotation structure for tower crane is supported, comprise undersetting 1, upper bracket 2 and single-revolution gear 3, this swiveling gear 3 is fixedly connected with this undersetting 1, this swiveling gear 3 is rotationally connected with this upper bracket 2, and this upper bracket 2 comprises two retarder mounting blocks 21, and this revolution is supported and comprised two retarders 4 and two drive motor 5, this retarder 4 is connected with this retarder mounting blocks 21, and this drive motor 5 is connected with this retarder 4.

The lower end of this retarder 4 is provided with a driven wheel 41, and this driven wheel 41 is connected with a joggle with this swiveling gear 3.

Below only with an embodiment, mentality of designing of the present invention is described, in the situation that system allows, the present invention can expand to external more functional module simultaneously, thereby expands to greatest extent its function.

The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
