Abstract
The utility model provides a worm drive lifting scaffold which aims at solving the technical problems that an existing scaffold hoisting device is instable in work and safety accidents are prone to generation. The worm drive lifting scaffold is fixed to a wall and provided with a guide rail. A hoisting device is installed along the guide rail. A lower hoisting point connecting rod is fixed to the hoisting device. A worm drive lifting mechanism is fixed to the lower hoisting point connecting rod. By the adoption of the worm drive lifting mechanism, hoisting operation of the hoisting device is achieved through climbing of a worm gear on a screw, so that according to the structure, connection is firm, ascent and descent are stable, large vibration is avoided, and safety accidents can be avoided.
Description
Technical field
The utility model relates to a kind of scaffold, is specifically related to a kind of worm-drive lifting false work.
Background technology
Tradition scaffold is generally to drive boom hoisting by electric block, and electric block is by being flexible coupling to drive boom hoisting, for example, drive boom hoisting to complete lifting up and down by chain or belt.This lifting method being flexible coupling, easily occurring is flexible coupling comes off, ruptures, and causes security incident, and buffering is larger owing to being flexible coupling, usually cause in lifting process boom hoisting operation not steady, easily cause article on boom hoisting to be shaken off, the same security incident that causes, also affects operating efficiency.
Summary of the invention
The technical problems to be solved in the utility model is existing scaffold boom hoisting job insecurity, easily causes security incident, for addressing the above problem, provides a kind of worm-drive lifting false work.
The purpose of this utility model realizes in the following manner:
Worm-drive lifting false work, scaffold is fixed on body of wall, and guide rail is set on scaffold, along orbit of guide rail, boom hoisting is installed, and on described boom hoisting, fixing lower suspension centre connecting rod, fixes worm-drive elevating mechanism on lower suspension centre connecting rod.
Described worm-drive elevating mechanism comprises worm gear, establishes screwed hole in worm gear, and the leading screw matching is set in screwed hole, and leading screw one end is fixed on body of wall; Worm gear periphery arranges worm screw, and worm screw is connected with motor.
Described leading screw one end is fixed on suspension centre connecting rod, and upper suspension centre connecting rod is fixed on body of wall.
Described upper suspension centre connecting rod is also connected with body of wall by diagonal member with guide rail.
Described worm gear and worm screw are all arranged in casing, and casing is bolted on lower suspension centre connecting rod; Worm screw one end connects gear wheel, and electric machine main shaft connects pinion, and gear wheel matches with pinion.
Described motor is fixed on cabinet exterior, and electric machine main shaft stretches in casing.
Difference fixed flange on described cabinet base and top cover, and flange is enclosed within on leading screw.
The screw thread of described leading screw is square thread.
With respect to prior art, the utility model adopts worm-drive elevating mechanism, utilizes worm gear climbing on leading screw to realize the lifting of boom hoisting, this structure, connect fastening, stable when oscilaltion, can there is not larger shake, can avoid the generation of security incident.

Detailed description of the invention
As shown in Figure 1, worm-drive lifting false work, scaffold is fixed on body of wall 8, and guide rail 1 is set on scaffold, along orbit of guide rail, boom hoisting 2 is installed, and on boom hoisting, fixing lower suspension centre connecting rod 3, fixes worm-drive elevating mechanism on lower suspension centre connecting rod 3.Described worm-drive elevating mechanism, adopts the transmission between worm and wheel exactly, drives boom hoisting lifting.
As shown in Figures 2 and 3, the worm-drive elevating mechanism that the utility model adopts comprises worm gear 5, establishes screwed hole 6 in worm gear 5, the leading screw 7 that the interior setting of screwed hole 6 matches, and leading screw 7 one end are fixed on body of wall 8; Worm gear 5 peripheries arrange worm screw 9, and worm screw is connected with motor 10.Driven by motor worm screw is rotated, and worm screw drives worm gear to rotate, and worm gear matches with leading screw by screwed hole, because leading screw one end is fixed on body of wall, worm gear rotates will be along leading screw lifting, and worm gear is relative with boom hoisting fixing, will drive like this boom hoisting oscilaltion.
Fixing employing leading screw one end between leading screw 7 and body of wall is fixed on suspension centre connecting rod 4, and upper suspension centre connecting rod 4 is fixed on body of wall.And upper suspension centre connecting rod can be fixed on the height on body of wall along with the height of boom hoisting lifting regulates it.
In order to increase the stability of guide rail and upper suspension centre connecting rod, upper suspension centre connecting rod 4 is also connected with body of wall by diagonal member 11 with guide rail 1.Diagonal member can increase the pulling force upwards to guide rail and upper suspension centre connecting rod, can be because boom hoisting be overweight stretch bending guide rail and upper suspension centre connecting rod.
In order to increase the stability of transmission and the sealing of working environment between worm and gear, worm gear 5 and worm screw 9 are all arranged in casing 12, casing 12 is bolted on lower suspension centre connecting rod 3; Being connected between worm screw and motor can directly be connected worm screw with electric machine main shaft; Also worm screw one end can be connected to gear wheel 13, electric machine main shaft connects pinion 14, and gear wheel matches with pinion, and drive mechanism can reduce the power of the work of motor like this, reduce power consumption, and Multi-stage transmission can increase the stability of work.Motor 10 is fixed on cabinet exterior, and electric machine main shaft stretches in casing.
Difference fixed flange 15 on cabinet base and top cover, and flange is enclosed within on leading screw 7.Threads of lead screw directly contacts with flange inner hole wall, flange can play position-limiting action to leading screw, and leading screw matches with the screwed hole of worm gear, can play the position-limiting action to worm gear, like this as long as worm screw is fixed on casing relatively, just can ensure worm gear work time, there will not be movement, do not need to increase other structures, just can meet the stable work of Worm Wheel System, make simple in structurely, assembling is simple.As shown in Figure 4, the screw thread of leading screw 7 is square thread, can increase the contact area of threads of lead screw and flange inner hole wall, makes it spacing more stable.
