Abstract
The utility model discloses a pitch winding mechanism of a hoist, which comprises a wire cable, a bracket, a wire press wheel, a fixed pulley, a limit device, a fixed pulley block and a girder. The pitch winding mechanism is characterized in that the wire press wheel is hinged with the fixed pulley through a pulling plate, and the wire press wheel can rotate at a fixed angle around the shaft of the fixed pulley; a stopper for preventing the rotation angle from exceeding fixed value is arranged in an upper limit position and a limit switch is arranged in a lower limit position; and the limit switch can be directly mounted in a position corresponding to the pulling plate. By adopting the mechanism, the reverse bending of the wire cable is reduced and the service life of the wire cable is prolonged; and the limit switch is directly mounted in a position corresponding to the pulling plate, thereby eliminating the limit device in the prior mechanism, simplifying the structure and improving the performances.
Description
Technical field
The utility model relates to a kind of pitch winding mechanism of crane, is specially adapted to the pitch winding mechanism of shore container crane.
Background technology
When existing shore container crane pitch winding mechanism process press rope wheel and fixed pulley, there is the bending of small distance reversing sense in steel rope, has shortened the service life of steel rope, and the inhibiting device complex structure of winding mechanism, poor performance.
Summary of the invention
Task of the present utility model is to propose a kind of steel rope that reduces to use the oppositely pitch winding mechanism of crane of bending of part, task of the present utility model is finished like this: it comprises steel rope, support, press rope wheel, fixed pulley, inhibiting device, fixed pulley group and crossbeam composition, it is characterized in that: press rope wheel employing arm-tie and fixed pulley are hinged, and press rope wheel can rotate with fixed angle around fixed pulley axis.Be provided with at upper limit position and prevent that the anglec of rotation from surpassing the block of given value, is provided with limit switch in the smallest limit position.Limit switch can directly be contained in and the corresponding position of arm-tie.The utlity model has following effect: reduced steel rope and used reverse bending partly, prolonged the service life of steel rope, inhibiting device is simple, and is safe and reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the structural representation that press rope wheel and fixed pulley are twined in existing pitching
Fig. 3 is the structural representation of press rope wheel of the present utility model and fixed pulley
The drawing explanation
1, reel 2, steel rope 3, support 4, press rope wheel 5, fixed pulley (a) (b) 6, inhibiting device 7, arm-tie 8, crossbeam
The specific embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing: press rope wheel 4 is hinged by arm-tie 7 and fixed pulley 5 (a), press rope wheel 4 can rotate with fixed angle around fixed pulley axis, establish block in the limes superiors position and prevent that the anglec of rotation from surpassing given value, the smallest limit position bit switch of limiting, when reel 1 lay winding wire ropes 2 pulling assembly pulleys 8 promptly spur crossbeam 9 and steeve, after crossbeam 9 reaches the limes superiors position, limited by the top stop location, corresponding limit switch action; When steel rope 2 puts down running block 8 and is crossbeam 9 levels, when steel rope 2 crossbeams 9 are up to the standard the position, steel rope 2 no pulling force, press rope wheel 4 and steel rope 2 are sagging under the deadweight effect, the lower position switch action.This mechanism has reduced the reversing sense bending of steel rope, because limit switch directly is contained in and the corresponding position of arm-tie, has saved the inhibiting device of former mechanism the service life of having improved steel rope, designs simplification, and performance is improved.
