Utility model content
For addressing the above problem, the utility model provides a kind of cantilever crane, and it can increase the moving range of the length direction of cantilever crane.
For achieving the above object, cantilever crane of the present utility model, comprise column, be arranged at described column upside and the revoliving arm that can rotate with respect to described column along continuous straight runs and the electric block for article hoisting, wherein, also comprise telescopic boom, described telescopic boom is installed on described revoliving arm below and can is driven and be reciprocatingly slided along the length direction of described revoliving arm by the first driver train, and described electric block is installed on described telescopic boom below and can is driven and be reciprocatingly slided along the length direction of described telescopic boom by the second driver train.
Preferably, described column upside is arranged at intervals with two back-up blocks vertical with described column, on two described back-up blocks, offer vertically relative pin-and-hole, the end of described revoliving arm is fixedly installed bearing pin, and described bearing pin two ends are rotatably installed in described pin-and-hole.
Preferably, described revoliving arm bottom is provided with slide rail, and described telescopic boom top is provided with multiple hangers that can slide along described slide rail.
Preferably, described the first driver train is for driving cylinder, and described driving cylinder is fixed on described revoliving arm below, and the top of described telescopic boom is provided with contiguous block, and the piston rod of described driving cylinder is fixedly connected with described contiguous block.
Preferably, described the first driver train is hydraulic actuating cylinder, and described hydraulic actuating cylinder is fixed on described revoliving arm below, and the top of described telescopic boom is provided with contiguous block, and the piston rod of described hydraulic actuating cylinder is fixedly connected with described contiguous block.
Cantilever crane of the present utility model, by setting up telescopic boom, and by the electric block that can reciprocatingly slide along telescopic boom length direction is installed on telescopic boom, has increased the moving range of cantilever crane at length direction, convenient operation, and article hoisting is more flexible.By position-limited lever being set on the bearing pin of revoliving arm and being undertaken spacingly by the block above column, effectively control the rotational angle of revoliving arm.Telescopic boom is by air cylinder driven, simple in structure, easy to operate.
Accompanying drawing explanation
Fig. 1 is the structural representation of cantilever crane of the present utility model.
The specific embodiment
Below, by reference to the accompanying drawings, structure of the present utility model and principle of work etc. are further described.
As shown in Figure 1, cantilever crane of the present utility model, for article hoisting, comprises column 1, is arranged at column 1 upside and the revoliving arm 2 that can rotate with respect to column 1 along continuous straight runs and for the electric block 4 of article hoisting.Can adjust at length direction for making cantilever crane, to meet the needs of small space, cantilever crane of the present utility model also comprises telescopic boom 3, telescopic boom 3 is installed on revoliving arm 2 belows and can is driven and be reciprocatingly slided along the length direction of revoliving arm 2 by the first driver train, and electric block 4 is installed on telescopic boom 3 belows and can is driven and be reciprocatingly slided along the length direction of telescopic boom 3 by the second driver train.
Column 1 can be fixedly installed on ground by base 20, to form bottom support.Rotation between revoliving arm 2 and column 1 can realize by which, column 1 upside is arranged at intervals with two back-up blocks 9 vertical with column 1, on two back-up blocks 9, offer vertically relative pin-and-hole (not indicating in figure), the end of revoliving arm 2 is fixedly installed bearing pin 5, and bearing pin 5 two ends are rotatably installed in pin-and-hole.Back-up block 9 can adopt welding etc. conventionally with being connected of column 1, and the bearing pin 5 of revoliving arm 2 ends is connected for revoliving arm 2 and column 1, after revoliving arm 2 is installed on column 1, by means of this bearing pin 5, revoliving arm 2 can be rotated.
For the rotational angle of restriction revoliving arm 2, can on column 1, cylinder be set, in the time that the piston rod of cylinder stretches out, can limit the rotational angle of revoliving arm 2.
Telescopic boom 3 can adopt all multimodes with the realization of revoliving arm 2 sliding block joints, preferred as one, and revoliving arm 2 bottoms are provided with slide rail (not indicating in figure), and telescopic boom 3 tops are provided with multiple hangers 8 that can slide along slide rail.Particularly, can be two or more.
The fore and aft motion of telescopic boom 3 can adopt all eurypalynous driver trains, preferred as one, the first driver train is for driving cylinder 6, driving cylinder 6 comprises cylinder body 601 and is positioned at the piston rod 602 of cylinder body 601, cylinder body 601 is fixed on revoliving arm 2 belows, the top of telescopic boom 3 arranges contiguous block 7, and cylinder piston rod 602 is fixedly connected with contiguous block 7.In the time driving the piston rod 602 of cylinder 6 to stretch, can drive telescopic boom 3 to move back and forth by contiguous block 7, to adjust the lifting length of the horizontal direction of cantilever crane.In addition, the first driver train can also be hydraulic actuating cylinder, and its set-up mode is consistent with driving cylinder 6.
The usual manner that is connected to of electric block 4 and telescopic boom 3, the second driver train moving along telescopic boom 3 for realizing electric block 4, can, by many conventional type of drive, can adopt scheme of the prior art, no longer description.
The integrated operation of cantilever crane, can control by control handle, is realized the unlatching of the first driver train and the second driver train and is closed by control handle, makes revoliving arm and telescopic boom move to target location.
