Description
Technical field
The utility model relates to a kind of air-resistance type lift work equipment falling proof device and uses the equipment of this device.
Background technology
The flexible main body of column type overhead operation elevator, generally by folded the forming of two to nine joint aluminum alloy mast groups, every joint mast makes built mast be promoted to object height by chain or rope hoisting.When chain or the unexpected fracture of steel rope, built mast has lost pulling force and has dropped suddenly, just is easy to take place safety misadventure, jeopardizes operating personal life.The traditional solution is to strengthen conservative factor, takes double-stranded bar perhaps to add measures such as coarse-wire rope, but can not deal with problems fully.
Summary of the invention
For addressing the above problem, the utility model provides air-resistance type lift work equipment falling proof device a kind of simple in structure, safe and reliable and uses the lift work equipment of this device.
The utility model is that the technical scheme that its problem of solution is adopted is:
A kind of air-resistance type lift work equipment falling proof device, by cylinder sleeve and in cylinder sleeve the piston rod of axial motion constitute; Said cylinder sleeve one end is provided with permanent seat, and permanent seat is provided with a deflation hole and communicates with cylinder sleeve; The end that said piston rod inserts cylinder sleeve is provided with piston, and its other end is provided with fixed end; Be provided with a valve between said piston and the deflation hole.
Preferably, said piston and cylinder sleeve are interference fit.
A kind of lift work equipment; Comprise by the folded jacking system that forms of some joint mast adjacent set; Some aforementioned each described a kind of air-resistance type lift work equipment falling proof devices are installed in the said jacking system; The fixed end of said falling proof device is installed in wherein and one saves on the mast, and its permanent seat is installed on the adjacent joint mast.
The beneficial effect of the utility model is: when mast rose, piston rod slowly separated in cylinder sleeve, and valve is opened in the air push cylinder sleeve, and piston rod can easily extend; The cylinder sleeve internal pressure slowly increases when the mast normal contraction, valve closure, but also leave small gaps gas leakage, and slowly discharge through deflation hole, piston and cylinder sleeve form the gassiness space of fully enclosed, and the pressure that this space produces slowly descends piston rod; Use the lift work equipment of the utility model, when fracture takes place in its chain or connecting device, the gas in the Piston Compression cylinder sleeve, but gas can all do not extruded at once, can effectively cushion the impulse force that mast weighs down following time, ensures the safety of operating personal; In addition, when needs are fallen bench board, only need to eliminate the pulling force of chain, the gas in the cylinder sleeve is slowly discharged in deflation hole, and mast just can slowly be fallen, and need not slowly to reduce pulling force, can save resource; This apparatus structure is simple, and cost is low, and is easy for installation, and most important is to protect personal security and equipment not to be damaged by actv..
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the structural representation of the utility model falling proof device;
Fig. 2 is the lift work device structure scheme drawing that has used the utility model.
The specific embodiment
A kind of air-resistance type lift work equipment falling proof device shown in accompanying drawing 1, the piston rod 12 that reaches motion in cylinder sleeve 13 by cylinder sleeve 13 constitutes; Said cylinder sleeve 13 1 ends are provided with permanent seat 15, and permanent seat 15 is provided with a deflation hole 16 and communicates with cylinder sleeve 13, and the diameter of said deflation hole 16 is enough little, so that gas can all not be discharged away at once; The end that said piston rod 12 inserts cylinder sleeve 13 is provided with piston 14; Said piston 14 can be the rub resistance elastomeric material; And with cylinder sleeve 13 be interference fit; In cylinder sleeve 13, to form a fully enclosed space, make the gas of this interior volume be merely able to discharge from deflation hole 16, the other end of piston rod 12 also is provided with fixed end 11; Between piston 14 and deflation hole 16, be provided with a valve 17.
A kind of lift work equipment shown in accompanying drawing 2; Comprise base; Be equipped with on the base by the folded jacking system that forms of some joint mast 2 adjacent set; The described a kind of air-resistance type lift work equipment falling proof device of some the utility model is installed in said jacking system, and the fixed end 11 of said falling proof device 1 is installed in wherein and one saves on the mast 2, and its permanent seat 13 is installed on the adjacent joint mast 2.
The top of jacking system is equipped with service platform 3, and service platform 3 one sides are provided with controller 4, during work; Operating personal operation control 4 rises service platform 3; Jacking system rises, and when mast 2 rose, piston rod 12 slowly separated in cylinder sleeve 13; Valve 17 is opened in the air push cylinder sleeve 13, and piston rod 12 can easily extend; Cylinder sleeve 13 internal pressures slowly increase when mast 2 normal contraction, and valve 17 is closed, but also leave small gaps gas leakage; And pass through deflation hole 16 and slowly discharge; Piston 14 and cylinder sleeve 13 form the gassiness space of fully enclosed, and the pressure that this space produces slowly descends piston rod 12.
Use the lift work equipment of the utility model, when fracture takes place in its chain or connecting device, the gas in the Piston Compression cylinder sleeve 13, but gas can all do not extruded at once, can effectively cushion mast 2 and weigh down the impulse force in following time, ensures the safety of operating personal; In addition, when needs are fallen bench board, only need to eliminate the pulling force of chain, the gas in the cylinder sleeve 13 is slowly discharged in deflation hole 16, and mast 2 just can slowly be fallen, and need not slowly to reduce pulling force, can save resource; This apparatus structure is simple, and cost is low, and is easy for installation, and most important is to protect personal security and equipment not to be damaged by actv..Also can a plurality of falling proof devices 1 be set, to play the better protection effect on same joint mast 2 according to the actual weight of bearing of equipment.
Above specification sheets is said, is merely the principle and the embodiment of the utility model, and every essence according to the utility model is carried out any simple modification and variation, all belongs within the desired protection domain of the utility model.
