Abstract
The utility model discloses an anti-twisting device for wirerope of a tower crane, characterized in that the device includes a screw rod, a connecting block connected the tag end of the screw rod, a pair of ear holders fixedly connected with the connecting block, a pin roll loaded on the ear holders, and a pulley loaded on the pin roll, wherein the screw rod is also sleeved with a centerpiece, an one-way thrust ball bearing is mounted on the screw rod in the centerpiece, the screw rod of the one-way thrust ball bearing side is provided with a locating nut, the centrepiece is arranged on a bumping part of a boom, and the tag end of the wire rope is rolled on the pulley. the utility model is capable of releasing an inverse torsion of the wirerope and preventing a hanging hook from rotating, so as to ensure no-failure operation of the tower crane.
Description
Technical field
The utility model relates to a kind of twisting-proof device of wire ropes for tower cranes.
Background technology
Steel rope is that most popular transmission is around the property part in the tower machine, and its advantage is: coiling is good, and load-carrying capacity is big, and from heavy and light, steady noiselessness during operation is suitable for the high speed transmission; Good springiness, the intensity height, overload capacity is strong, unexpected fracture can not take place during work, and is reliable, obtains widespread use.Yet in the use of tower machine, hoist rope can occur and beat the strand situation, this is to be caused by the structure that has tower machine steel rope system now, this system as shown in Figure 1, hoist rope 11 compresses the back via the steel rope wedge wedging of reel 15 or briquetting and is emitted by the reel 15 of lifting mechanism, through tower cap weight limits device pulley 17, transition segment leading sheave 12, amplitude variation trolley pulley 13, lifting hook pulley group 14, the end of steel rope 11 is fixed on the bearing pin 16 of crane arm top portion; Because many little steel rope coilings of steel rope 11 usefulness form, self there is anti-torsion, the end of steel rope 11 is to be fixed on the bearing pin 16, steel rope 11 can't discharge the anti-torsion of self, cause the lifting hook pulley group section of steel rope to be twined mutually, cause the suspension hook rotation, the serious consequence that causes the tower machine to work.
The utility model content
The purpose of this utility model is the above-mentioned deficiency at prior art, and a kind of wire ropes for tower cranes twisting-proof device is provided, and it can discharge the anti-torsion of steel rope self, avoids the suspension hook rotation, thereby guarantees the normal operation of tower machine.
For achieving the above object, wire ropes for tower cranes twisting-proof device of the present utility model, it is characterized in that comprising screw rod, a pair of folder ear that connects firmly with the terminal bonded assembly contiguous block of screw rod, with contiguous block, be loaded on this to the bearing pin on the folder ear, be loaded on the pulley on the bearing pin, on screw rod, also be set with crosshead, on the screw rod in crosshead single direction thrust ball bearing is installed, on the screw rod of single direction thrust ball bearing one side, be provided with setscrew nut, crosshead is installed in the portion of crane arm top, steel rope terminal rolling on pulley.
When steel rope was worked, the torsion that self produces drove pulley, bearing pin, folder ear, contiguous block, makes screw rod rotate in crosshead, thereby discharged the torsion that self produces, and avoided the suspension hook rotation, thereby guaranteed the normal operation of tower machine.
As further improvement of the utility model, on setscrew nut and screw rod, be provided with pin-and-hole radially, a spring cotter is loaded in the pin-and-hole; Can prevent the nut displacement, guarantee the long-time normal operation of single direction thrust ball bearing;
In sum, the utility model can discharge the anti-torsion of steel rope self, avoids the suspension hook rotation, thereby guarantees the normal operation of tower machine.
Description of drawings
Fig. 1 is the constructional drawing of existing tower machine steel rope system.
Fig. 2 is the front view of the utility model embodiment.
Fig. 3 is the birds-eye view of Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figures 2 and 3, this wire ropes for tower cranes twisting-proof device, comprise screw rod 1, a pair of folder ear 3 that connects firmly with screw rod 1 terminal bonded assembly contiguous block 2, with contiguous block 2 welding, be loaded on this to the bearing pin 4 on the folder ear 3, be loaded on the pulley 5 on the bearing pin 4, on screw rod 1, also be set with crosshead 6, on the screw rod 1 in crosshead 6 single direction thrust ball bearing 7 is installed, on the screw rod 1 of single direction thrust ball bearing 7 one sides, be provided with setscrew nut 8, be provided with pin-and-hole radially on setscrew nut 8 and screw rod 1, a spring cotter 9 is loaded in the pin-and-hole; Crosshead 6 is installed in the portion of crane arm top, steel rope 10 terminal rolling on pulley 5.
When steel rope 10 work, the torsion that self produces drives pulley 5, bearing pin 4, folder ear 3, contiguous block 2, makes screw rod 1 rotate crosshead 6 in, thereby discharges the torsion that self produces, and avoids suspension hook to rotate, thus the normal operation of assurance tower machine; Spring cotter 9 can prevent nut 8 displacements, guarantees single direction thrust ball bearing 7 long-time normal operation.
Claims (2)
1. wire ropes for tower cranes twisting-proof device, it is characterized in that comprising screw rod, a pair of folder ear that connects firmly with the terminal bonded assembly contiguous block of screw rod, with contiguous block, be loaded on this to the bearing pin on the folder ear, be loaded on the pulley on the bearing pin, on screw rod, also be set with crosshead, on the screw rod in crosshead single direction thrust ball bearing is installed, on the screw rod of single direction thrust ball bearing one side, be provided with setscrew nut, crosshead is installed in the portion of crane arm top, steel rope terminal rolling on pulley.
