The utility model belongs to the technical field of electric hoists, and provides an electric hoist which can avoid the problem that steel wire ropes are entangled together. The electric hoist comprises a motor, a transmission mechanism, a reel, steel wire ropes and a lifting hook device, wherein the motor is in transmission connection with the reel through the transmission mechanism. The electric hoist further comprises a steel wire rope anti-entanglement device which comprises an upper body, a lower body and a shaft, wherein through holes which extend along the lifting direction of the lifting hook device and used for the shaft to penetrate through are respectively formed in the upper body and the lower body, the upper body and the lower body are hinged through the shaft and are kept on the shaft, one ends of the steel wire ropes are wound on the reel, the other ends of the steel wire ropes pass through a pulley of the lifting hook device and are connected with the lower body, and the upper body is connected with a steel wire rope head fixing part. Due to the steel wire rope anti-entanglement device, the upper body and the lower body of the steel wire rope anti-entanglement device can relatively rotate, the steel wire ropes can rotate relative to the steel wire rope head fixing part to release twisting force on the steel wire ropes, and the purpose of preventing steel wire rope entanglement can be achieved.
Description
Technical field
The utility model belongs to the technical field of electric block.
Background technology
Electric block is a kind of small lifting equipment, and it mainly is comprised of transfinite device and cargo hook gear of motor, transmission device, reel, steel rope, rope guide, safety.Because electric hoist suspension hook below 5 tons is light, length of steel rope, distance cause the winding major cause; Cause motor load to increase after the winding, increase afterwards together the steel rope load around knot, strengthen steel rope abrasion.Simultaneously, single rope is stressed during rising, and safety overload device is not protected the police, and the stressed safety overload of attachment point single wire rope device is protected alertly during decline, can not operate up and down and cause that equipment is unsettled to be hung.In the lifting working process, two steel ropes appear after together phenomenon of knot, need with the hands with two around together steel rope separately, turn motionless owing to steel rope self torsion is excessive; If misoperation simultaneously as easy as rolling off a logly causes two steel ropes counter-rotatings; Steel rope is accelerated rotation during counter-rotating, does not slightly note causing finger to crush.
Untiing in the process of knot, sometimes cause counter-rotating, rotate when too fast, then cause the distortion of steel rope serious distortion, at this moment, must be changed; Otherwise, can't marshalling in reel, even cause the rope guide extrusion fracture, cause safety misadventure.
Summary of the invention
The purpose of this utility model provides a kind of steel rope of can avoiding around knot electric block together.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of electric block, comprise motor, transmission device, reel, steel rope and cargo hook gear, motor is in transmission connection by transmission device and reel, also comprise the steel rope device for anti-knotted, this steel rope device for anti-knotted comprises the upper body, lower body and axle, be equipped with the through hole that extends and supply axle to pass along cargo hook gear lifting direction in upper body and lower body, upper body and lower body are hinged by this axle and upper body and lower body remain on this axle, one end of steel rope is wrapped on the reel, the pulley that the other end is walked around cargo hook gear is connected with lower body, and the upper body is connected with the steel wire rope head fixed part.
On the basis of such scheme and as the preferred version of such scheme: described upper body is connected with the steel wire rope head fixed part by length of cable.
On the basis of such scheme and as the preferred version of such scheme: be provided with the safety device that transfinites at described length of cable.
On the basis of such scheme and as the preferred version of such scheme: the transfinite housing of device of described upper body and described safety is structure as a whole.
On the basis of such scheme and as the preferred version of such scheme: between axle and upper body, also be provided with axle sleeve.
On the basis of such scheme and as the preferred version of such scheme: between axle and lower body, also be provided with axle sleeve.
On the basis of such scheme and as the preferred version of such scheme: the steel wire rope head fixed part is for being used for installing the frame of reel.
On the basis of such scheme and as the preferred version of such scheme: the position of steel rope device for anti-knotted is positioned near the steel wire rope head fixed part.
The utility model compared to existing technology outstanding and useful technique effect is: electric block of the present utility model has adopted the steel rope device for anti-knotted, can relatively rotate between the upper body of this steel rope device for anti-knotted and the lower body, so that the relative steel wire rope head fixed part of steel rope can relatively rotate, to discharge the twisting resistance on the steel rope, prevent that to reach steel rope is around the purpose of knot.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged drawing at A place among Fig. 1.
The specific embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-Fig. 2;
A kind of electric block comprises motor 1, transmission device 2, reel 3, steel rope 4 and cargo hook gear 5, and motor 1 is in transmission connection by transmission device 2 and reel 3.These and prior art are as good as, and repeat no more here.For reach prevent steel rope around the knot purpose, set up steel rope device for anti-knotted 6 at existing electric block.This steel rope device for anti-knotted 6 comprises upper body 61, lower body 62 and axle 63, be respectively equipped with the through hole 611 that extends and pass for axle along cargo hook gear lifting direction at upper body and lower body, upper body 61 and lower body 62 are hinged by this axle 63 and upper body 61 and lower body 62 remain on this axle 63.The pulley 51 that one end of steel rope is wrapped on the reel 3, the other end is walked around cargo hook gear 5 is connected with lower body 62, and upper body 61 is connected with steel wire rope head fixed part 8.Electric block of the present utility model has adopted the steel rope device for anti-knotted, can relatively rotate between the upper body of this steel rope device for anti-knotted and the lower body, so that the relative steel wire rope head fixed part of steel rope can relatively rotate, to discharge the twisting resistance on the steel rope, prevent that to reach steel rope is around the purpose of knot.
