Abstract

The utility model relates to a steel wire rope anti-loosening device for a gantry crane. The device is characterized by comprising a pulley cover (1), two sleeves (2) and a bent pipe (3), wherein the two sleeves (2) are arranged at two inner ends of the pulley cover (1) through a pin shaft (4); the bent pipe (3) is arranged in the pulley cover (1) between the two sleeves (2); and the two sleeves (2) and the bent pipe (3) are positioned on the same arc surface. The steel wire rope anti-loosening device for the gantry crane can be suitable for steel wire ropes which move at a high speed, so that the stability of the steel wire ropes in the moving process is improved, the steel wire ropes can be effectively prevented from being loosened from a pulley, the using safety of the crane is improved, and the maintenance frequency is reduced.

Description

High pedestal jib crane steel rope groove separation preventing device
Technical field
The utility model relates to a kind of span winch steel rope groove separation preventing device.Belong to the elevator machinery technical field.
Background technology
Span winch as port logistics, build the major equipment of ship enterprise, have higher frequency of utilization and and worker's production efficiency, what stand in the breach so is that each operating mechanism of span winch also will have faster speed.Because speed is fast, steel rope stability in pulley in the process of "---static---motion of moving " has reduced, and is easy to cause steel rope to take off groove, and this brings hidden danger to harbour production and work safety.
Before the utility model was made, the way of traditional gate seat crane rope anticreep groove mainly was when structure design, to increase the cornerite of steel rope on pulley, suitably reduces the steel rope kinematic velocity.Owing to increase the structural shape that the steel rope cornerite might increase complete machine during design, reduce the steel rope kinematic velocity, reduced the work efficiency of hoisting crane again, and the steel rope anticreep groove effect that obtains neither be very remarkable.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of and can prevent effectively that the span winch steel rope from taking off the device of groove.
The purpose of the utility model is achieved in that a kind of high pedestal jib crane steel rope groove separation preventing device; It comprises pulley cover, two sleeve pipes and bend pipe; Said two sleeve pipes are arranged at the two ends, inside of pulley cover through bearing pin, and said bend pipe is arranged in two pulley covers between the sleeve pipe.
Said two sleeve pipes and bend pipe are on the same arc surface.
Compared with prior art, the beneficial effect of the utility model is:
The utility model high pedestal jib crane steel rope groove separation preventing device, applicable to the steel rope of high-speed motion, the stability when having improved the steel rope motion prevents that effectively steel rope from taking off groove from pulley, has increased the safe in utilization of hoisting crane, reduces frequency of maintenance.

The specific embodiment
Referring to Fig. 1-Fig. 2, the utility model relates to a kind of high pedestal jib crane steel rope groove separation preventing device, mainly is made up of pulley cover 1, two sleeve pipes 2 and bend pipe 3; 1 one-tenth on said pulley cover is fan-shaped; Be placed on the pulley 5, the bottom of pulley cover 1 is fixed on the pulley journal stirrup 6, and said two sleeve pipes 2 are arranged at the two ends, inside of pulley cover 1 through bearing pin 4; Definitely be to be arranged at advancing a little and going out a little of steel rope; Said bend pipe 3 is arranged in two pulley covers 1 between the sleeve pipe 2, and two sleeve pipes 2 are on the same arc surface with bend pipe 3, and radian is identical with the radian of pulley 5; The groove of pulley 5, two sleeve pipes 2 and bend pipe 3 define the motion space of steel rope 7, prevent that effectively steel rope from taking off groove from pulley.

Claims (2)

1. high pedestal jib crane steel rope groove separation preventing device; It is characterized in that it comprises pulley cover (1), at least two sleeve pipes (2) and bend pipe (3); Said two sleeve pipes (2) are arranged at the two ends, inside of pulley cover (1) through bearing pin (4), and said bend pipe (3) is arranged in the pulley cover (1) between two sleeve pipes (2).
