Abstract
The utility model discloses an anti-collision device for a landing leg of a crane. The anti-collision device comprises a steel wire rope, a turnbuckle, a spring, a connecting block, an upper rigid bracket, a lower rigid bracket, an induction limiter, an induction block and a guiding wheel, wherein the steel wire rope is connected with the upper rigid bracket and the lower rigid bracket through the guiding wheel; the turnbuckle is mounted on the steel wire rope; the end part of the steel wire rope is connected with the spring through the connecting block; the induction block is fixed on the connecting block; the induction limiter is fixed on the lower rigid bracket; and the upper rigid bracket and the lower rigid bracket are both fixed on one landing leg of the crane. The anti-collision device for the landing leg of the crane is used for preventing the accident that a hung article collides with the landing leg of the crane before a trolley is in a stopping position when the edge of the hung article exceeds a hanging point by a certain distance.
Description
Technical field
The utility model relates to a kind of anticollision device, particularly relates to a kind of hoisting crane supporting leg anticollision device.
Background technology
At present hoisting crane supporting leg anticollision device all adopts the mode of control dolly position, be provided with in the land of trolley travelling usually slow down spacing, stop spacing, the limit is spacing.Reduce speed now when spacing when dolly touches to slow down, touch and stop when spacing out of servicely,, then will promptly stop if in time not out of service and touch the limit when spacing.The mode of this control dolly position only is applicable to that hoisting point position is near hanging object edge; When hanging object edge exceeds the suspension centre certain distance; Dolly does not normally stop as yet, and institute's object that hangs has just struck the hoisting crane supporting leg, thereby can't play the effect of safety guard-safeguard.
The utility model content
The utility model technical matters to be solved provides a kind of hoisting crane supporting leg anticollision device, and it prevents when hanging object edge exceeds the suspension centre certain distance, and dolly institute's object that hangs before stop position has just touched the accident of hoisting crane supporting leg.
The utility model solves above-mentioned technical matters through following technical proposals: a kind of hoisting crane supporting leg anticollision device; It is characterized in that; It comprises steel rope, turnbuckle, spring, contiguous block, go up rigid support, rigid support, induction limiting device, sensor block, track adjusting wheel down, is connected through track adjusting wheel between steel rope and last rigid support, time rigid support, and turnbuckle is installed on the steel rope; The end of steel rope is connected with spring through contiguous block; Sensor block is fixed on the contiguous block, and the induction limiting device is fixed on down on the rigid support, and last rigid support, following rigid support all are fixed on the hoisting crane supporting leg.
The positive progressive effect of the utility model is: the utility model prevents when hanging object edge exceeds the suspension centre certain distance, and dolly institute's object that hangs before stop position has just touched the accident of hoisting crane supporting leg, raising safety.
Description of drawings
The structural representation of the utility model hoisting crane supporting leg anticollision device when Fig. 1 does not touch steel rope for the object that hangs.
Fig. 2 touches the schematic diagram of the utility model hoisting crane supporting leg anticollision device behind the steel rope for the object that hangs.
Fig. 3 is the structural representation of steel rope, spring, sensor block etc. in the utility model.
The specific embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to specify the technical scheme of the utility model.
Extremely shown in Figure 3 like Fig. 1; The utility model hoisting crane supporting leg anticollision device comprises steel rope 1, turnbuckle 2, spring 3, contiguous block 4, goes up rigid support 51, following rigid support 52, induction limiting device 6, sensor block 7, track adjusting wheel 8; Steel rope 1 is with last rigid support 51, be connected through track adjusting wheel 8 between the rigid support 52 down; Turnbuckle 2 is installed on the steel rope 1, and the end of steel rope 1 is connected with spring 3 through contiguous block 4, and sensor block 7 is fixed on the contiguous block 4; Induction limiting device 6 is fixed on down on the rigid support 52, and last rigid support 51, time rigid support 52 all are fixed on the hoisting crane supporting leg 9.
Last rigid support, following rigid support all are fixed on the hoisting crane supporting leg through welding or bolt connection mode; Steel rope is suspended on the place ahead of hoisting crane supporting leg; Steel rope is regulated tensioning degree through turnbuckle, and realizes turning to through the track adjusting wheel that is fixed on the rigid support, and the end of steel rope is connected with spring through contiguous block; Sensor block is fixed by bolts on the contiguous block, and the induction limiting device is fixed on down on the rigid support.When hanging object 10 to hoisting crane supporting leg 9 near the time, touch steel rope 1 earlier, make steel rope 1 bending; Because steel rope 1 can not be elongated itself, so will elongate spring 3, sensor block 7 links together through contiguous block 4 and spring 3; When spring 3 was elongated, sensor block 7 was also along with moving together, when sensor block 7 during near induction limiting device 6; Dolly promptly stops, and institute's object that hangs 10 of dolly is also along with promptly stopping, thereby has avoided the bump of institute's object that hangs 10 and hoisting crane supporting leg 9.
The utility model prevents when hanging object edge exceeds the suspension centre certain distance, and dolly institute's object that hangs before stop position has just touched the accident of hoisting crane supporting leg, raising safety.
Those skilled in the art can carry out various remodeling and change to the utility model.Therefore, the utility model has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
