Summary of the invention
For overcoming the deficiencies in the prior art, solve the problem that ruptures suddenly when steel rope, the invention provides a kind of wire cable rupture protection system.Can in time avoid under unexpected situation, in a single day wire cable rupture taking place, guarantee suspended object safety, and can under the operating mode of various danger, use, avoid serious accident to take place when steel rope.
For achieving the above object, the present invention adopts following technical scheme:
Described wire cable rupture protection system, has the safety pole device that is used for anchor clamps beam or hanging beam synchronization lifting, be used to clamp or decontrol the catch gear of safety pole device, be used to control the control setup that clamps or decontrol, be used for providing the sensing device of wire cable rupture signal to control setup; Be engraved in the locking scope of catch gear during the safety pole device of described lifting; Described catch gear is positioned on the fixing bench board; Described sensing device is monitored the situation of wire cable rupture constantly, works as wire cable rupture, and sensing device is transferred to control setup with break signal, reset attachment work, and catch gear pins the safety pole device, and weight is not fallen downwards, plays the effect of safety guard-safeguard.
Described wire cable rupture protection system, safety pole device are a cylindrical safety pole, have annular boss from level to level around it, and each boss cross section is trapezoidal; The safety pole lower end is arranged on the anchor clamps beam hanging beam, and safety pole is with upper guide bush outward, and upper guide bush is the open circles cover, and upper guide bush is fixed on the bench board by bolt B 1 by the upper guide bush backing plate.
Described wire cable rupture protection system, catch gear are by a pair of clamp that is provided with on the bench board clamp base and a pair of arm-tie is hinged constitutes; On the clamp base, the arm-tie other end is hinged on the electromagnet by connecing button the clamp other end by bolted splice, and electromagnet is fixed on the bench board by the electromagnet base.
Described wire cable rupture protection system, sensing device are pressure sensor, and pressure sensor is arranged on cylinder and steel rope position contacting.
Described wire cable rupture protection system, reset attachment is made of retracing spring, push rod, permanent seat, and permanent seat is provided with movably push rod, is with retracing spring on the push rod, and an end of push rod connects electromagnet, and the permanent seat of push rod is arranged on the bench board.
Because adopt aforesaid technical scheme, the present invention has following preceence:
This wire cable rupture protection system can in time be avoided under unexpected situation in a single day wire cable rupture taking place when steel rope, adopts clamp to block safety pole, makes by hoisting heavy and does not fall downwards, plays the effect that guarantees the suspended object safety guard-safeguard.The present invention is particularly useful for solving the problem that wire cable rupture appears in the less driving of lifting altitude.The present invention can also play the protection steel rope, prolongs the effect of rope service-life.And can under the operating mode of various danger, use, avoid serious accident to take place.

The specific embodiment
As shown in Fig. 1,2: this wire cable rupture protection system, has the safety pole device that is used for anchor clamps beam or hanging beam synchronization lifting, be used to clamp or decontrol the catch gear of safety pole device, be used to control the control setup that clamps or decontrol, be used for providing the sensing device of wire cable rupture signal to control setup; The safety pole device of described lifting is a cylindrical safety pole 10, has annular boss from level to level around it, and each boss cross section is trapezoidal; The safety pole lower end is fixed on anchor clamps beam or the hanging beam, and safety pole is with upper guide bush 7 outward, and upper guide bush is exactly a columniform open circles cover, and it is enclosed within on the safety pole all the time, guarantees that by it safety pole vertically moves up and down all the time.Upper guide bush is fixed on the bench board 13 by bolt B 1, nut B2, packing ring B3 by the upper guide bush backing plate.Be engraved in during the safety pole device in the locking scope of catch gear; Described catch gear constitutes by a pair of clamp 2 that is provided with on the bench board clamp base 6 and a pair of arm- tie 3,4 are hinged; Clamp 2 other ends on clamp base 6, and guarantee that clamp 2 can rotate around bolt by bolted splice.Arm- tie 3,4 other ends are hinged on the electromagnet 8 by connecing button 5, and electromagnet is fixed on the bench board 13 by the bolt and nut packing ring by electromagnet base 9.8 other ends of electromagnet link to each other with the push rod of reset attachment 12.Catch gear is positioned on the fixing bench board 13; Described sensing device is that pressure sensor is arranged on cylinder and steel rope position contacting.Sensing device is monitored the situation of wire cable rupture constantly, works as wire cable rupture, and sensing device is transferred to control setup with break signal, reset attachment 12 work, and reset attachment pins the safety pole device by catch gear.Described reset attachment 12 is made of retracing spring, push rod, permanent seat, and permanent seat is provided with movably push rod, is with retracing spring on the push rod, and an end of push rod connects electromagnet, and the permanent seat of push rod is arranged on the bench board 13.
During use, when weight hoists, drive the safety pole be fixed on anchor clamps beam or the hanging beam 10 with hanging object to rising, allow electromagnet charged simultaneously, clamp 2 opens, and weight is hoisted smoothly.When wire cable rupture, the electromagnet outage, push rod makes a pair of arm- tie 3,4 drive clamp 2 closures by retracing spring, makes clamp 2 block safety pole 10, and the lifted weight thing is not fallen downwards, plays the effect of safety guard-safeguard.The upper guide bush 7 of cover is fixed near the bench board of fixing the lifting mechanism 13 on the safety pole 10.
The present invention can also play protection and prolong rope service-life, when weight will remain on certain altitude, can allow the electromagnet outage, and it is stressed that clamp 2 closures reduce steel rope, thereby prolongs steel rope service life.
