Description
Technical field
The utility model relates to a kind of crane, particularly a kind of crane runway backing plate levelling gear.
Background technology
At present, the crane that stationary track runs, has certain requirement to the levelness after track installation.Existing track installation, directly pre-embedded bolt is arranged in concrete, then backing plate is penetrated bolt and stretch out concrete external part, be laid on concrete upper surface, although such mounting means is feasible, it is the levelness that cannot ensure backing plate, therefore, directly affects the levelness of track, the security of operation of crane is served and causes impact.
Utility model content
The purpose of this utility model is just to provide a kind of crane runway backing plate levelling gear that can regulate track pad.
The purpose of this utility model is realized by such technical scheme, a kind of crane runway backing plate levelling gear, comprise concrete and the backing plate being positioned at concrete upper surface, vertically pre-embedded bolt is provided with in described concrete, one end of described pre-embedded bolt passes concrete and backing plate, the upper surface of described backing plate is provided with track, described pre-embedded bolt is provided with the adjusting device for spacer plate level.
Wherein, described adjusting device is adjusting nut, and described adjusting nut is positioned on described pre-embedded bolt, and is positioned at the below of backing plate.
Owing to have employed technique scheme, the utility model has structure advantage simple, easy to operate, with low cost, adopts it can regulate the levelness of backing plate, meets the levelness of crane runway, improve the security of operation of crane.
Accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail; but the utility model is not limited to these embodiments; any improvement or alternative on the present embodiment essence spirit, still belongs to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, a kind of crane runway backing plate levelling gear, comprise concrete 1 and the backing plate 2 being positioned at concrete 1 upper surface, pre-embedded bolt 3 is vertically provided with in described concrete 1, one end of described pre-embedded bolt 3 passes concrete 1 and backing plate 2, the upper surface of described backing plate 2 is provided with track 4, described pre-embedded bolt 3 is provided with the adjusting device for regulating backing plate 2 level.
Further, described adjusting device is adjusting nut 5, and described adjusting nut 5 is positioned on described pre-embedded bolt 3, and is positioned at the below of backing plate 2.
In the utility model, by the adjustment of spanner to adjusting nut 5, serve the leveling of the levelness to backing plate 2, ensure that the levelness of track 4.
