The rocking handle is connected with an axle sleeve on a middle core axle, two pinion wheels arranged on the axle sleeve can be respectively meshed with two gearwheels, so one hand rocking device can be used for respectively driving two objects to lift. The utility model has the advantages of simple and novel structure, small size, strong self locking capability, safety, etc. The utility model can also be used for lifting type airing clothing suspension brackets with double rods, etc.
Description
The utility model relates to a kind of hand rope coiler that makes object up-down.
Make the object rising or descend very common in daily life with the rope coiler.Generally speaking, rope coiler can only be controlled the lifting of an object.A kind of hand rope coiler of being made up of bull wheel, uni-directional brake, jiggle bar etc. is disclosed as Chinese patent ZL9521680.1.This rope coiler for need distinguish lifting at same place if any two objects the time, just must be installed two hand rope coilers.
The purpose of this utility model is to overcome the weak point of existing rope coiler, design a kind of hand rope coiler of doubly-linked of novel structure, can handle two rope reels respectively with a wind, realize to drive respectively the lifting action of two objects with a hand rope coiler.
The utility model comprises frame, jiggle bar and rope wind2.Frame is made up of back plate, header board and several pillars that supports forward and backward plate.Frame inside is provided with two cover rope wind2s.Every cover rope wind2 is made of the reel and the uni-directional brake that are loaded on the same mandrel.Uni-directional brake is made up of the big gear wheel of the reel of the band screw rod that is arranged in order, friction lining, brake wheel, band nut and the braking spring that is set in the brake wheel outer ring.Braking spring one end is fixed on the pillar, and the other end is a free end.Two cover rope wind2s are installed on header board and the back plate by mandrel respectively, but direction is opposite each other.Middle mandrel has the axle sleeve of a band miniature gears outward, and the inner of middle mandrel is installed on the plate of back, and the other end penetrates the inside of axle sleeve, and axle sleeve is connected with jiggle bar by pin after passing header board, and two miniature gearss on the axle sleeve can mesh with two big gear wheels respectively.Middle mandrel is provided with the retainer spring steel ball, and there are two grooves that cooperate with positioning ball axle sleeve inside.
The utility model, have novel structure, simple, volume is little, self-lock ability is strong, advantage such as safe and reliable.Regulate drum diameter, the number of teeth of big miniature gears and the length of jiggle bar connecting rod, just can adapt to the requirement of various lifting dynamics.Can be applicable to as two bar lifting mode airers etc.
Following embodiment further specifies structure of the present utility model and principle of work in conjunction with the accompanying drawings.
Fig. 1 and Fig. 2 are the structure principle chart of present embodiment, and wherein Fig. 2 is A-A cutaway view of Fig. 1.
The hand rope coiler of this doubly-linked is made up of frame, two reels, two groups of uni-directional brakes and a jiggle bar.
With reference to accompanying drawing, frame by frame after plate 3, frame header board 8, several pillars 4 form.Two ends of pillar 4 are shaped on step, can be through in the corresponding hole of the forward and backward plate of frame, two ends of pillar 4 are stretched out the termination riveted joint of the forward and backward plate of frame after, just formed frame.The bottom of the back plate of frame is shaped on for the hole 18 that usefulness is installed.Three axles are arranged on the frame, and wherein middle one is mandrel 13 in the jiggle bar, and two on next door is respectively the mandrel 11 of 1# reel and 2# reel.
Reel 5 and uni-directional brake are contained on the same mandrel 11.Uni-directional brake is made up of the reel 5 of braking spring 6, brake wheel 7, friction lining 10, band screw rod and the big gear wheel 9 of band nut.The big gear wheel of the reel of band screw rod and band nut is formed screw pair.Uni-directional brake and reel constitute the rope wind2.Two cover rope wind2s are installed on the frame by mandrel 11 respectively, but direction is opposite each other, and for example, the reel of 1# rope wind2 is in header board 8 one sides, and the reel of 2# rope wind2 is in back plate 3 one sides.The principle of work of uni-directional brake is as follows: braking spring 6 limits freely turning to of brake wheels 7, and an end of braking spring 6 is fixed on the pillar, and the other end is a free end.From the front of Fig. 1, two brake wheels 7 can only freely rotate by anticlockwise direction.The weight of the 1# object that promotes and 2# object draw two rope reel 5 clickwises respectively by 1 # halliard 1 and 2# halliard 2.The rotary orientation of screw pair is arranged like this: when the rope reel is drawn by rope, big gear wheel is drawn close to reel.Present embodiment be dextrorotation with 1#, and 2# is left-handed.Thereby big gear wheel 9 and reel 5 clamp brake wheel 7, friction lining 10, and rope can not be eased out voluntarily.
Jiggle bar 15 is connected by the axle sleeve 13 of pin 14 with the band miniature gears, thereby drives its rotation and translation.When current post-tensioning pushed away jiggle bar 15, two miniature gearss on the axle sleeve 13 meshed with two big gear wheels 9 respectively, and when pulling out forward (position shown in Figure 2), jiggle bar 15 links to each other with the big gear wheel of 2# reel.Be example with the 2# reel now, its principle of work is described: with reference to Fig. 1, cw shakes jiggle bar 15, drives big gear wheel 9 inhour rotations, because of the 2# screw pair is left-handed, so big gear wheel 9 meetings and reel 5 hold brake wheel 7, friction lining 10 tighter.But owing to 2# braking spring 6 does not limit brake wheel 7 inhour rotations, so reel 5 can follow big gear wheel 9 together with brake wheel 7 inhour rotations, thereby rolling 2# halliard 2 drives the 2# object and rises.When inhour is shaken jiggle bar 15, drive big gear wheel 9 clickwises.Because of the 2# screw pair is left-handed, thus big gear wheel 9 can separate with reel 5, thereby loosen the brake drum 7, friction lining 10.The 2# halliard is under the effect of weight of object, and traction reel 5 is followed big gear wheel 9 clickwises, till reel 5 and big gear wheel 9 clamp brake wheel 7, friction lining 10.If the 2# halliard is provided with load, when then back-up ring 12 is run in (Fig. 2) motion to the right during big gear wheel 9 clickwises, also can drives reel 5 rotations, thereby ease out 2# halliard 2.The principle of work of 1# reel is identical with the 2# reel, and jiggle bar is pushed backward, makes the miniature gears and the engagement of the big gear wheel on the 1# reel of axle sleeve 13 rear ends, and operation is with the 2# reel.
