Abstract

The utility model relates to a light lift which relates to the light-duty labour lift machine, specially suitable for rapid escaping of the inhabitant when the high building is firing, climbing up and down the aperture of the mine, erecting the pipeline of the altitude electric wire, overhauling the altitude device, exploring on the mountain and the cliff, etc. One end of a rope is hung on the hook with a buffer, and the other end is winded on a drum. The hook is hung on one fixture capable of bearing stress, and the user with the lift descends. A speed controller limits the maximum descending speed to ensure safely descending, and a stopper realizes exact positioning. The user turns a handle, so the lift and the user can rise together. So the light lift can completely descend, rise and position.

Description

Light lift

The utility model relates to a kind of light decline, the machinery that rises, be particularly suitable for skyscraper the fleeing from rapidly of resident when catching fire, from bank to bank the cave, set up electric overhead line pipeline, maintenance eminence equipment, high mountains and steep cliffs exploration etc.

At present, when skyscraper catches fire,, often cause resident's injures and deaths owing to there is not lifesaving appliance; Well or mine are to adopt traditional instrument---winch about the people, both need a plurality of personnel operation, use again inconvenient; Set up the electric overhead line pipeline, when maintenance eminence equipment and crag were explored, people generally were bundled in oneself an end of rope, the other end is handled control by others and is realized, not only bother but also can not accurately locate, and tying body because of rope, the staff is also uncomfortable.

Task of the present utility model provides a kind of safe ready, by the light lifter tool of the own one man operation control of worker.

This task has been solved by the following characteristics technology: the worker puts on work clothes, and work clothes is hung on the lifter, and the hook that will have energy disperser hangs on the stressed fixture of a certain energy.The end of restricting lies in hook, and the other end is on reel.Ratchet interlock on ratchet and the reel stops reel to rotate towards putting the rope direction.Handle the handle of control ratchet, the interlock of ratchet and ratchet is broken away from.Under people and lifter action of gravity, reel just rotates towards putting the rope direction, and people and lifter descend together.(lifter is positioned at the front), reel is started the arbor high speed revolution through speed increasing gear train regiment commander, the circular cone dish of the speed controller on this and the friction force that is fixed between the circular cone dish on the frame hinder the increase of drum speed, thereby reach the purpose of control descending speed.The pulling force of governing speed controller upper spring has just been determined the maximum speed that people and lifter descend in advance.If want to be parked in aerial a certain position, only need the handle of operation control ratchet, make ratchet and ratchet interlock, reel just stops operating, and people and lifter are parked in desired location.Under ratchet and ratchet interlock condition, turning handle drives reel and rotates towards the serving direction, and then people and lifter are done upward movement.

The utlity model has following characteristics:

1, operation and control are independently carried out by worker one people fully.

2, the descending speed controller performance is good, and is safe and reliable.

3, the worker wears work clothes rather than is tying body with rope.

4, equipment package adopts light material, and is in light weight, is easy to carry.

5, use the preceding dead work time short.

6, revolute pair adopts antifriction-bearing box, the mechanical efficiency height, and the time human-saving rises.

Feature details of the present utility model will further be set forth by means of drawings and Examples, should not be interpreted as the embodiment that this is limited to utility model certainly.

The people puts on work clothes 4, with being hooked on the frame 8 on the work clothes.Having on the stressed fixed object of a certain energy of being hooked on of energy disperser 1.Operating handle 5, eccentric wheel 23 are thrown off the ratchet 7 and the interlock of ratchet 9, and the people is being with lifter to leave areal of support.Under the action of gravity of people and lifter, reel 10 rotates towards putting the rope direction, and people and lifter descend together, and reel 10 makes axle 21 high speed rotating through the speedup of

gear

22,11,12,13,14.The circular cone dish 19 of the centrifugal speed controller 17 on (at this moment, handle 16 is on the screw 15, and axle 21 does not drive handle 16 rotation) axle 21 and be fixed on the unlimited increase that friction force between the circular cone dish 20 on the frame 8 has hindered drum speed.The pulling force of regulating spring 18 has just been determined the maximum speed that people and lifter descend in advance.Operating handle 5, the thrust of 23 pairs of ratchets 7 of eccentric wheel reduces, and compression spring 6 makes ratchet 7 and ratchet 9 interlocks, and reel promptly stops operating, and people and lifter are parked in desired location.Under ratchet 7 and ratchet 9 interlock conditions, turning handle 16, reel rotates towards the serving direction, and the lifter band the people and is risen.

Claims

Light lifter, it is characterized in that the people puts on work clothes (4), with being hooked on the frame (8) on the work clothes, having being hooked on the stressed fixed object of a certain energy of energy disperser (1), operating handle (5), eccentric wheel (23) is thrown off the ratchet (7) and the interlock of ratchet (9), the people is being with lifter to leave areal of support, under the action of gravity of people and lifter, reel (10) rotates towards putting the rope direction, people and lifter descend together, reel (10) makes axle (21) high speed rotating through the speedup of gear, the speed controller of axle (21) has been controlled the maximum speed that reel descends, operating handle (5), eccentric wheel (23) reduces the thrust of ratchet (7), compression spring (6) makes ratchet (7) and ratchet (9) interlock, reel stops operating, people and lifter are parked in desired location, under ratchet (7) and ratchet (9) interlock condition, turning handle (16), reel (10) rotates towards the serving direction, and the lifter band the people and is risen, the effect of support (3) is the exit position of tricing line (2), makes rope be in the centre of lifter all the time to the pulling force of lifter.
