Abstract
The utility model discloses a mining crane, which is very convenient to use. The crane comprises a base and a workbench, wherein a steering device for rotating the workbench is arranged between the base and the workbench, and comprises a bearing pedestal mounted on the base and a rotating shaft mounted on the bottom surface of the workbench; the rotating shaft is matched with the bearing pedestal in a rotating manner; and the crane further includes at least two pulleys mounted on the base, and the pulleys are uniformly distributed along the circumference of the bearing pedestal and are matched with the bottom surface of the workbench in a rolling manner. Through the crane, a heavy object can be conveyed in a mine not only in the extension direction of a rail, but also from one side of the rail to the other side of the rail, so as to realize multidirectional conveyance of the heavy object.
Description
Technical field
The utility model relates to a kind of crane that is used for hoisting heavy under the coal mine.
Background technology
At present, the crane that is used for coal mine generally comprises base and is positioned at bench board on the base, and the roller that rolls and cooperate with the track of coal mine is installed on the base, and the winch, chevron pointing support arm and the clump weight that are used to coil wire sling are installed on the bench board.This crane in use since bench board be set directly on the base, so bench board base rotation relatively, make that weight is sling after, the weight change of direction can only can't be transported weight along the track bearing of trend, cause the use of this kind crane very inconvenient.
The utility model content
The technical matters that the utility model solves provides a kind of mining crane easy to use.
The technical scheme that its technical matters that solves the utility model adopts is: mining crane, comprise base and bench board, and be provided with the steering hardware that is used for rotary table between described base and the bench board.
Further be: described steering hardware comprises the bearing seat that is installed on the base, also comprises the rotating shaft that is installed on the bench board bottom surface, described rotating shaft and described bearing seat normal-running fit.
Further be: also comprise at least two pulleys that are installed on the base, described pulley is circumferentially uniform and roll with the bottom surface of bench board and to cooperate along bearing seat.
The beneficial effects of the utility model are: by steering hardware, bench board is rotated according to actual needs, and then can makes the weight that is lifted by crane send to the destination by the rotation of bench board, use very convenient.In addition, by several pulleys are set, it is more level and smooth on the one hand bench board to be rotated, and helps bench board on the other hand and keep balance in rotary course.
Description of drawings
Fig. 1 is the scheme drawing of mining crane of the present utility model.
Be labeled as among the figure: 1-bench board, 2-base, 3-pulley, 4-bearing seat, 5-rotating shaft, 6-winch, 7-wire sling.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
As shown in Figure 1, mining crane comprises base 2 and bench board 1, is provided with the steering hardware that is used for rotary table 1 between described base 2 and the bench board 1.Above-mentioned steering hardware can for: rotatable rotating disk is set on base, on the bottom surface of bench board support platform is installed, support platform and rotating disk contact matching can make the relative base of bench board be rotated like this.Preferred implementation is: described steering hardware comprises the bearing seat 4 that is installed on the base 2, also comprises the rotating shaft 5 that is installed on bench board 1 bottom surface, described rotating shaft 5 and described bearing seat 4 normal-running fiies.
During use, by winch 6 weight that hangs on the wire sling 7 is sling earlier, by artificial push work platform 1 bench board 1 relative base 2 is rotated then, after rotating to the destination, by winch 6 weight is unloaded again.Because bench board can rotate relative to base, not only weight can be transported along the track bearing of trend, weight can also be transported to opposite side from track one side, weight is multi-aspect transports in realization, uses very convenient.
Keep balance in order to help bench board in rotary course, also comprise at least two pulleys 3 that are installed on the base 2, described pulley 3 is circumferentially uniform and roll with the bottom surface of bench board 1 and to cooperate along bearing seat 4.Adopt said structure,, make bench board in rotary course, can keep balance preferably, and it is more smoothly smooth and easy that bench board is rotated because bench board is subjected to the rolling supporting role of a plurality of pulleys in rotary course.Above-mentioned pulley can be 2,3, and 4 or other quantity.
