Background technology

Along with progress and the development of society, elevator utilization in house property industry is more aobvious generally.But the problem of the safe operation of elevator is also especially aobvious prominent.Analyzing according to statistics, the probability that all kinds of elevator accidents occur is respectively;Door system accident accounts for 75%；Rush to summit or slip ladder etc. accident account for 20%；Other accidents account for about 5%.And often result in personnel injury major break down in, 40% by rush to summit or slip ladder etc. accident cause.

Currently in order to prevent elevator from rushing to summit or slip ladder etc. accident, in lift car, hoist ropes guide wheel, guide rail relevant position, limiter of speed and the overspeed protection safety device such as safety tongs or rope brake are installed.In these hypervelocity safety guards, limiter of speed is driven by lift car, hoist ropes, is arranged on the centrifugal switch in limiter of speed, when hoist ropes rope speed reaches setting value, touches electric contact and makes the overspeed protection safety device action such as safety tongs or rope brake.Traction sheave is hung under one, steel wire rope car, hangs counterweight under the pile warp guide wheel of steel wire rope other end, traction sheave main shaft is provided with encoder, provide signal for the properly functioning control system CPU central processing unit of elevator.To above-mentioned hypervelocity safety guard without direct correlation.

Prevent elevator from rushing to summit at present or slip ladder etc. accident hypervelocity safeguard protection there is serious defect.It is no matter rush to summit or slip ladder; all all adopt: when elevator speed reaches the normal speed 1.25 times of national regulation; the safety tongs installed in lift car, hoist ropes guide wheel, guide rail relevant position, limiter of speed, or the mode that the overspeed protection safety device such as rope brake just works.At this moment due to the effect of acceleration, kinetic energy produced by car is relatively big, because car is on the basis of gait of march, adds again the effect of acceleration, produces the superposition of inertia, then make above-mentioned safety device operationally braking kinetic energy strengthen, and safety arrestment is very easily malfunctioning.There is potential safety hazard.During above-mentioned overspeed protection safety device braking simultaneously, due to spot speed sudden change when car is braked, cause jerk inertial impact force to ladder personnel, be also easily caused personal injury event.And, during current Elevator landing, due to the fault such as elevator machine and control, or loading capacity is uprushed or anticlimax, and leveling opening can be caused to slip ladder.It is no matter rush to summit or slip ladder; all all adopt: when elevator travel line speed reaches 1.15-1.25 times of nominal linear speed (certain definite value being generally within the scope of 60 ms/min-120 ms/min) (speed of service reaches 69 ms/min-150 ms/min); the limiter of speed installed in lift car, hoist ropes guide wheel, guide rail relevant position and safety tongs, or the mode that the overspeed protection safety device such as rope brake just works.Except limiter of speed, above-mentioned overspeed protective device all can not work, and this set is then easily caused the human casualty accident of turnover personnel during flat bed.

Current traction machine is except above-mentioned overspeed protective device; also has a kind of brake auxiliary device introduced in patent documentation application number 200680000338.0; rotatable roller is brought pressure to bear on by means of electric magnet; roller is pressed against on the rotation rope sheave hanging with main rope, it is suppressed that the skidding when brake hard of the main rope.

A kind of non-skid braking auxiliary device introduced in patent documentation application number 200680000338.0, is a kind of with electromagnetic force for brake positive pressure, acts on the mode of braking in rope sheave rope face.And electromagnetic braking, its braking distance is can not to be determine value.Because the traction sheave of traction machine and steel wire rope, after certain work timing, it is uncertain that the diameter of the wear condition of traction sheave race and steel wire rope deformation reduces situation, thus braking distance is uncertain.When adopting electromagnetic braking, between electromagnetism conducting magnet core and movable block, it is necessary to leave sufficient safe distance, thus make air strengthen every magnetic space.Have a strong impact on the brake force of electromagnetism.Directly result in the minimizing of brake positive pressure.The rotatable brake roller that document is discussed, contacting with the longitudinal direction of the main rope in rope sheave upper surface braking point is linear contact lay, because of regardless of whether adopt which kind of brake positive pressure, through rotatable roller press main rope surface on the upside of traction sheave, for vertical line action by contact power.On the downside of corresponding main rope and the increase of frictional force between race, but the region that local is only small, it is bordering on linear contact lay.Thus the increase of good frictional force can not be obtained.And traction sheave has many independent steel wire ropes, after certain work timing, the diameter minimizing of the abrasion of traction sheave race and steel wire rope deformation is and differs.Therefore along traction sheave longitudinally same cross section on the upside of each steel wire rope, will not at same straight line.Then rotatable auxiliary roller described in document, can only brake two in several steel wire ropes.Also the steel wire rope after braking, the bigger frictional force of corresponding traction sheave race can not just more be produced.Thus this mode of braking is a conception of species.Can not normally implement.Also it is impracticable main cause after this patent disclosure.
