Description
Technical field
The utility model relates to a kind of hanging basket lifting means, the particularly hanging basket hoisting of a kind of pair of key pedal.
Background technology
Along with the development of urban construction, skyscraper is more and more.The hanging basket elevator that is used for aloft work then arises at the historic moment.
Hanging basket hoisting in the past mainly contains two kinds of Lever Blocks and electric lifts.Lever Blocks uses relatively effort, and efficient is low, and noise is big, and has only the protection of sliding cave, poor stability, and steel rope abrasion is serious.Electric lift cost height, energy dissipation is big, maintenance difficult, and operate underaction in the work.
Occurred a kind of foot pedal type hanging basket elevator for these reasons afterwards, its lifting power produces by pedal, and simple to operate, flexible, work efficiency increases, but it still has many defectives on technical performance.It is reasonable inadequately to be provided with as its transmission device, and pedal is very painstaking during work, and elevator adopts the singly-bound braking safety relatively poor.
Summary of the invention
In order to solve the problems referred to above that existing pedal elevator exists, the utility model provides a kind of pair of key pedal hanging basket hoisting, and it has improved elevating drive mechanism, and has adopted two key brake mode, and is not only simple to operate laborsaving, and has improved safety performance.
The technical solution of the utility model is as follows:
A kind of pair of key pedal hanging basket hoisting, comprise body, threaded shaft, driving gear, transmission gear and rope sheave, threaded shaft laterally is installed in body upper, stretcher is equipped with at the two ends of axle, driving gear and rope sheave are sleeved on the threaded shaft side by side, transmission gear is housed below them, and transmission gear is meshed with driving gear and rope sheave simultaneously, the centre of described threaded shaft is provided with outside thread, be provided with negative thread in the centre hole of driving gear, driving gear is sleeved on the outside thread of threaded shaft, at the engine body exterior of driving gear one side holdback is housed, and the ratchet of this holdback is fixedly mounted on the threaded shaft, the shell of holdback is by being bolted on the body, on the holdback housing, following position vertically is provided with two square holes, and a brake key and a coil tension spring respectively are housed in each hole, and nose end is equipped with fixing screw.The brake key of installing in the described check body shell is a square button, and an end of key has the oblique angle, and this oblique angle can insert in the hook tooth.
Described in the utility model pair of key pedal hanging basket hoisting compared with existing foot pedal type hanging basket hoisting, has the following advantages:
1.. adopted intermediate drive gear, increased transmitting ratio, make simple to operate laborsaving.
2. adopt two key brake mode in the braking link, increased job security.
Description of drawings
Fig. 1 is the structural representation of two key pedal hanging basket hoisting.
Fig. 2 is the rope sheave structural scheme of mechanism of two key pedal hanging basket hoisting.
The specific embodiment
With reference to Fig. 1, two key pedal hanging basket hoisting comprise body 1, threaded shaft 4, driving gear 13, transmission gear 7 and rope sheave 14.
Threaded shaft 4 laterally is installed in the top of body 1, and stretcher is equipped with at the two ends of axle, and driving gear 13 and rope sheave 14 are sleeved on the threaded shaft 4 side by side, transmission gear 7 is housed below them, and transmission gear 7 is meshed with driving gear 13 and rope sheave 14 simultaneously.
The centre of described threaded shaft 4 is provided with outside thread, be provided with negative thread in the centre hole of driving gear 13, driving gear 13 is sleeved on the outside thread of threaded shaft 4, engine body exterior in driving gear 13 1 sides is equipped with holdback 6, the ratchet 5 of holdback 6 is fixedly mounted on the threaded shaft 4, the shell of holdback 6 is by being bolted on the body 1, vertically be provided with two square holes at the upper and lower position of holdback housing, a brake key 3 and a coil tension spring 2 respectively are housed in each hole, and nose end is equipped with fixing screw.
The brake key of installing in the described holdback 6 body shells 3 is a square button, and an end of key has the oblique angle, and this oblique angle can insert in the tooth of ratchet 5.
With reference to Fig. 2, guide wheel 18 and pinch roller 16 are fixed on the body 1 by wheel carrier 17, the turnover direction of control steel rope 19, steel rope 19 is rounded in the V-shaped groove of rope sheave 14, increase the friction force of steel rope and rope sheave, prevent back skating, spring is housed on the wheel carrier 17 makes pinch roller 16 and rope sheave 18 clamp steel rope 19, increase the dynamics that pulls of 14 pairs of steel ropes 19 of rope sheave.Rope sling 20 is welded on the direction of control steel rope 19 on the body 1.
During work, anticlockwise direction is pedaled pedal, the threaded shaft anticlockwise motion and by threaded function in driving gear, move to the holdback direction the stressed back of driving gear, ratchet with holdback after being adjacent to holdback rotates counterclockwise with threaded shaft together, two keys forward slide on holdback, and this moment, hanging basket was raised.
When stopping to pedal, driving gear is subjected to the equipment action of gravity, and clockwise direction rotates, the holdback that on threaded shaft, moves right, desire drives ratchet and clockwise rotates, and this moment, two tight ratchets of knob of key limited the threaded shaft reversing, driving gear and holdback are in braking mode, and this moment, hanging basket was static.
When cw was pedaled pedal, driving gear moved right on threaded shaft and breaks away from unfilial son's device, and when moving to threaded tip and threaded shaft up time direction motion together, this moment, hanging basket descended.
The utility model is simple in structure, operates lightly, safe and reliable, is highly suitable for exterior wall brushing, cleaning and the elevator of high-rise building, the operations such as installation of curtain wall.
