Abstract
The invention relates to a steel wire rope retaining device for a portal crane. The steel wire rope retaining device is characterized by comprising a pulley cover (1), two sleeves (2) and an elbow (3), wherein the two sleeves (2) are internally arranged at two ends of the pulley cover (1) through a hinge pin (4); the elbow (3) is arranged in the pulley cover (1) between the two sleeves (2); the two sleeves (2) and the elbow (3) are positioned on the same arc surface. The steel wire rope retaining device provided by the invention is suitable for steel wire ropes in high-speed movement, improves the moving stability of the steel wire ropes, effectively prevents the steel wire ropes in the pulley from getting out of the track, increases the using safety of the crane, and reduces the maintenance frequency.
Description
Technical field
The present invention relates to a kind of span winch preventing wire rope from falling slot 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 cable slot disengaging, and this brings hidden danger to harbour production and work safety.
Before the present invention made, the way of traditional gate seat crane rope anticreep groove mainly was to increase the cornerite of steel rope on pulley when structure design, 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 again the work efficiency of hoisting crane, and the preventing wire rope from falling groove effect that obtains neither be very remarkable.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of device that can effectively prevent the span winch steel cable slot disengaging is provided.
The object of the present invention is achieved like this: a kind of high pedestal jib crane preventing wire rope from falling slot device, it comprises pulley shield, two sleeve pipes and bend pipe, described two sleeve pipes are arranged at the two ends, inside of pulley shield by bearing pin, and described bend pipe is arranged in two pulley shields between the sleeve pipe.
Described two sleeve pipes and bend pipe are on the same arc surface.
Compared with prior art, the invention has the beneficial effects as follows:
High pedestal jib crane preventing wire rope from falling slot device of the present invention, 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 use safety of hoisting crane, reduces frequency of maintenance.

The specific embodiment
Referring to Fig. 1-Fig. 2, the present invention relates to a kind of high pedestal jib crane preventing wire rope from falling slot device, mainly by pulley shield 1, two sleeve pipes 2 and bend pipe 3 form, 1 one-tenth of described pulley shield is fan-shaped, be placed on the pulley 5, the bottom of pulley shield 1 is fixed on the pulley journal stirrup 6, described two sleeve pipes 2 are arranged at the two ends, inside of pulley shield 1 by bearing pin 4, definitely be to be arranged at advancing a little and going out a little of steel rope, described bend pipe 3 is arranged in two pulley shields 1 between the sleeve pipe 2, two sleeve pipes 2 and bend pipe 3 are on the same arc surface, 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 preventing wire rope from falling slot device, it is characterized in that it comprises pulley shield (1), at least two sleeve pipes (2) and bend pipe (3), described two sleeve pipes (2) are arranged at the two ends, inside of pulley shield (1) by bearing pin (4), and described bend pipe (3) is arranged in the pulley shield (1) between two sleeve pipes (2).
