Abstract

The utility model provides a cantilever type lifter for lifting materials in industrial enterprises and delivered dishes and tableware in catering industry. A steel wire rope rotary plate and a steel wire rope wound on the rotary plate are arranged on a transmission shaft driven by a worm-gear reducer, the end of the steel wire rope is fixed with a cantilever type carrying box, and the carrying box is movably connected with a track through an upper roller set and a lower roller set. The cantilever type lifter achieves reliable self-lock brake through worm gear, the steel wire rope is smoothly taken-up and paid-off by the steel wire rope rotary plate to ensure that rollers in the roller sets of the cantilever type carrying box are organically matched with the track, so that the cantilever type carrying box has strong self-adaptability when operating on the track. The cantilever type lifter improves the safety performance of the product and greatly reduces equipment noise, and not only can stably lift articles, but also can effectively brake, stably runs with uniform acceleration or deceleration and reliably achieves the rope woolding without using a rope guiding device. The cantilever type lifter has the advantages of simple and reasonable structure, convenient installation and use, reliable operating performance, low cost and good effect, and is suitable for generalization.

Description

The cantilevered gig

Technical field

The utility model relates in a kind of mechanical manufacturing field the lifting means of delivery weight, relates in particular to a kind of lifting means of light and low noise.

Background technology

At present, the gig of known employing rope hoisting weight generally is made up of control apparatus, motor, gear reduction unit, circle tube, steel rope, basket, track.Driven gear reductor behind the electrical power, and then drive the rotation of circle tube, circle tube lay winding wire ropes, steel rope pulling basket promotes the realization elevating function to weight.Its complex structure, cost are higher.And the track of existing gig is difficult to guarantee parallelism and straightness accuracy in the running length scope, easy jam or loosening when causing the basket operation, make equipment discontinuity, operation not steady, and send big noise, add that the noise that gear reduction unit produces will make noise bigger.Also because existing gig does not have rope-arranging mechanism mostly, in the process of lay winding wire ropes, be easy to disorder cable, cause equipment operation steadily with to the wearing and tearing aggravation of steel rope, even rope-arranging mechanism is arranged, steel rope also can swing, and the pulling force of basket is presented periodically variable force, and the pulling force size direction that basket is subjected to becomes cyclical variation, not only influence the basket smooth running, also can bring bigger potential safety hazard.

Summary of the invention

Task of the present utility model is to provide a kind of cantilevered gig, and purpose is an easy jam or loosening when solving the operation that known gig exists, and the operation of equipment unbalance stress is not steady, and the poor stability noise is big, the problem that the complex structure cost is high.

The purpose of this utility model is achieved in that the cantilevered gig comprises motor controller, electrical motor, worm-gear speed reducer, transmission shaft, steel rope rotating disk, steel rope, basket, track and roller, mainly be on the transmission shaft that worm-gear speed reducer drives, the steel rope that twines on steel rope rotating disk and the rotating disk to be set, steel cord ends and cantilevered basket are fixed, again with two roller set and the track flexible connection up and down of basket warp.

Described roller set is the coupling assembling that is made of roller that is provided with on symmetrical two stands and the two stands and bearing pin, and the roller position opposite in two roller set places track two respective side respectively up and down.

The cantilevered gig is compared with known gig and is had the following advantages and good effect: because the cantilevered gig has been taked described technical scheme, make worm and gear realize the failure-free self-locking and braking, the steel rope rotating disk is to the smooth-going folding and unfolding of steel rope, the roller of guaranteeing the set roller set of basket cooperates with the organic of track, very strong adaptivity when being orbited, the cantilevered basket is arranged, significantly strengthened the security of products energy, obviously reduced the equipment noise, it can not only steadily promote article, and can effectively brake, the even steady light operation of (subtracting) speed, the reliable rope woolding under no rope-arranging mechanism situation of adding.And has low effective, a suitable advantage such as promote of simple and reasonable, easy to install, reliable working performance, cost.

The specific embodiment

Cantilevered gig by Fig. 1, Fig. 2 signal is made up of for primary member motor controller, electrical motor 1, worm-gear speed reducer 2, transmission shaft 3, steel rope rotating disk 4, steel rope 5, basket 6, track 7, roller 8.At first form actuating unit, on the transmission shaft 3 that the worm-gear speed reducer 2 of this actuating unit drives, steel rope rotating disk 4 is set and the steel rope 5 that is wrapped on the steel rope rotating disk 4 constitutes transmission device of the present utility model by motor controller, electrical motor 1, worm-gear speed reducer 2, transmission shaft 3.And be fixed on track 7 tops.Steel rope 5 is single-row row's rope, and captive joint with cantilevered basket 6 rear lowers in the end, basket 6 is moved up and down along with the folding and unfolding of steel rope 5.Be arranged with two roller set up and down on the basket 6, described roller set is the coupling assembling that is made of roller 8 that is provided with on symmetrical two stands and the two stands and bearing pin.Roller 8 position opposite in two roller set up and down, roller 8 in two roller set places 7 liang of respective side of track respectively, since the center of gravity of basket 6 not in two parallel orbits 7 in the heart, make cantilevered basket 6 move up and down in the process track 7 produced respectively and push away, draw application force at track 7.Parallelism and straightness accuracy to track 7 in operational process have certain comformability.Gu and effectively avoided jam or loosening phenomenon, make operation more steadily light, and reduce noise.This gig is by the rotating at motor controller control motor 1, and worm-gear speed reducer 2 is reliably realized transmission self-locking and brakings.Thereby the purpose that reliable realization carries cargo.
