Abstract
The utility model discloses a rotary support with a double-rotary structure for a tower crane. The rotary support with the double-rotary structure for tower crane comprises a lower support, an upper support and a rotary gear, wherein the rotary gear is fixedly connected with the lower support, and the rotary gear is connected with the upper support in rotation mode. The upper support comprises two reducer mounting blocks, and the rotary support comprises two reducers and two drive motors. The reducers are connected with the reducer mounting blocks, and the drive motors are connected with the reducers. The rotary support with the double-rotary structure for the tower crane has the advantages of being provided with double drive motors and double reducers, thus the tower crane can work normally when one drive motor or one reduce is damaged. Meanwhile, the volume of a single drive motor or a single reducer is smaller.
Description
Technical field
The utility model relates to a kind of revolution to be supported, and more precisely a kind of revolution of the two revolving structures of band for tower crane is supported.
Background technology
Comprise in the tower crane that a revolution support is used 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 is supported and is positioned at the 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.
The utility model content
The utility model mainly is to solve 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 of the two revolving structures of the band that is used 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 utility model is mainly solved by following technical proposals:
The revolution of the two revolving structures of a kind of band for tower crane is supported, comprise undersetting, upper bracket and single-revolution gear, described swiveling gear is captiveed joint 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 the utility model preferred embodiment, 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.
Therefore the advantage that supports of the revolution of the two revolving structures of band for tower crane of the present utility model is, with two drive motor and dual reducer, after drive motor or retarder damaged, hoisting crane still can work, and the volume of single drive motor and retarder is also less simultaneously.
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.
Fig. 1 is the perspective view that the revolution of the two revolving structures of the band for tower crane of the present utility model 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 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 two drive motor and dual reducer that the utility model provides, after drive motor or retarder damage, hoisting crane still can work, and the revolution of the two revolving structures of the band that is used for tower crane that the volume of single drive motor and retarder is also less is simultaneously supported.
As shown in Figure 1, the revolution of the two revolving structures of a kind of band for tower crane is supported, comprise undersetting 1, upper bracket 2 and single-revolution gear 3, this swiveling gear 3 is captiveed joint 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 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.
