Abstract
The invention relates to an anti-twisting rope winding device, comprising a shell, a first support, a second support, a hub and a motor, and further comprising a press plate and a tension spring, wherein a rope is wound around the hub; the motor is used for driving the hub to rotate; the back part of the press plate can swing up and down and is supported between the first support and the second support, and the lower end surface of the press plate is pressed on the rope wound around the hub; the lower end of the tension spring is fixed on a connection shaft at a middle part between the first support and the second support, and the upper end of the tension spring is fixed on the press plate so that the press plate keeps a trend of pressing the rope wound around the hub downwards. When the rope begins a sign of irregular superposition in a rope winding process, the press plate presses down the rope to be level with an upper stage so as to prevent the rope from scattering, reduce abrasion of a steel wire rope caused by scattered rope, simultaneously ensure that the rope is uniformly and orderly wound around the hub and effectively avoid a situation that the rope is badly wound and is clamped due to alternative superposition in the rope winding process.
Description
Technical field
The present invention relates to a kind of rope wrap-up, relate in particular to a kind of antiwind rope wrap-up, this device is suitable for drawing on drafting tools such as cucurbit and the various winder.
Background technology
Electric block is mainly used in and promotes or the traction object; Mainly comprise electrical motor, be arranged on the operation reductor on the service meter, be arranged on the cucurbit outer cover of service meter below; Be arranged on the reel in the cucurbit outer cover; The suspension hook group that is arranged on cucurbit outer cover below constitutes, and is installed with electrical motor on the cucurbit outer cover, is provided with reductor in the cucurbit outer cover.Like the patent No. is the Chinese utility model patent " a kind of electric block " of ZL201020629621.3 (notification number is CN201882839U); Reaching the patent No. is the Chinese utility model patent " a kind of electric cucurbit " of ZL200920296981.3 (notification number is CN201605125U), and they have all disclosed the structure of electric block.The prior electric cucurbit is generally used as large-scale lifting appliance; And be fixed on certain eminence and use, generally only use as upwards drawing object, however a lot of occasion; As needing the traction object in the factory building or on the road, the prior electric cucurbit has been used with regard to being inconvenient to so.
To the deficiency of aforementioned present situation, the applicant has invented a kind of portable hand-held electric block, comprises the shell with handle, and the rear end of shell is equipped with aft hook; First support and second support, they are parallel to each other and are spaced apart and arranged in the shell; Wheel hub rotatably is supported between said first support and second support, is wound with rope on the said wheel hub, and the front end that the free end of rope passes shell links to each other with front hook; Motor is supported between said first support and second support, and the axially spaced-apart certain distance of this motor and said wheel hub, and the output shaft of this motor is in transmission connection through reduction gearing mechanism and said wheel hub and rotates with drive hub.
But aforementioned electric block is not owing to there is antiwind structure; Steel wire cable in the existing wheel hub is freely to arrange in turning course; Steel wire cable is rambling arranges and can cause in the electric block steel wire cable to be overlapping and at random, causes producing very big friction drag between the steel wire cable, causes the wearing and tearing of steel wire cable; Also easily because of twining confusion, the inhomogeneous steel wire cable stuck phenomenon that produces; Cause steel wire cable revolution not smooth, use inconveniently, and arrange owing to steel wire cable is disorderly and unsystematic and to reduce the length that wheel hub holds steel wire cable.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of rope that can drive to be wrapped in the antiwind rope wrap-up on the wheel hub to above-mentioned prior art present situation uniform sequentially; Rope in this device is not easy to wear in wrapup procedure, and card rope phenomenon can not occur.
