Description

A kind of progressive safety gear of anti-falling safety device
Technical field
The utility model relates to the safety guard parts that lifting machinery security fields, particularly car (cage) antistall falls.
Background technology
In jacking equipment; Like the car of elevator, the elevator cage of building operation prevents that the anti-falling safety device that its stall is fallen from mainly being after the velocity limiter action; Drive voussoir or eccentric wheel safety tongs and clamp guide rail; Or block is set at car (cage), and make car (cage) stop, prevent that falling accident from taking place.The car that running velocity is low (cage) impulsive force is less, can adopt instantaneous formula anti-falling safety device, but bigger owing to its impulsive force for the higher car of running velocity (cage), so the associated safety regulation and stipulation must adopt gradual anti-falling safety device.For how judging that anti-falling safety device is gradual or instantaneous formula, with reference to the record of correlation technique data, instantaneous formula safety clamp and gradual safety clamp there are definition very clearly, be defined as: voussoir is gone up sliding along the pincers seat when safety tongs moves; Because of ramp effect, the gap disappears very soon, makes voussoir clamp guide rail; Because pincers seats is a rigidity, voussoir is from clamping guide rail to car (cage) stop, the time compole short; Do not have obvious stopping distance, impact the Judas, be called instantaneous formula safety clamp; Progressive safety gear is claimed elastic safety pincers or sliding safety tongs again, and it and the instantaneous safety key distinction structurally is that the pincers seat is an elastic construction.This safety tongs is made up of voussoir and elastic component, when voussoir is mentioned the clamping guide rail, makes stressed the opening of pincers seat, between voussoir and pincers seat inclined-plane slippage takes place, and the slippage result is further strutted elastic component, produces braking force stop car.Owing to have slipping, the impulsive force of car when stop greatly reduced.
Traditional gradual voussoir safety tongs is when voussoir is mentioned the clamping guide rail; Voussoir back, both sides is provided with one " U " shape spring; Make stressed the opening of pincers seat that a buffering course arranged; To realize reducing impulsive force, because the elasticity of its " U " shape spring is a definite value, the safety tongs of certain model can only be fixed on certain load and responsiveness uses adaptive surface narrower.It is also higher to make requirement, and cost is bigger.
The utility model content
In order to solve above-mentioned technical matters, the purpose of the utility model provides a kind of progressive safety gear of anti-falling safety device safe and reliable, simple in structure.
The utility model solves the technical scheme that its technical matters adopted:
A kind of progressive safety gear of anti-falling safety device; Comprise the pincers seat, said pincers seat one end is installed with slipper, and the said pincers seat other end is provided with voussoir, voussoir guide rail, connecting rod, trigger mechanism, bearing seat, the tension spring that is used to clamp; Rotatable fork is installed on the said bearing seat; Said fork one end is captiveed joint with the pincers seat other end through tension spring, and the said fork other end is connected with voussoir through connecting rod, and said trigger mechanism is pressed on the fork.
Further, be provided with arc elastic leaf springs in the said voussoir guide rail as preferred embodiment.
Further, also be provided with adjustable bolt between said tension spring and the pincers seat as preferred embodiment.
Further as preferred embodiment, the contact surface of said voussoir and guide rail is provided with first pad that is used to increase friction force.
Further as preferred embodiment, the contact surface of said slipper and guide rail is provided with second pad that is used to increase friction force.
Further, be provided with pressure spring between said slipper and the pincers seat as preferred embodiment.
Further as preferred embodiment, said safety tongs is monolateral wedge shape, wedge shape guide rail clamping structure,
Or bilateral wedge shape, wedge shape guide rail clamping structure.
The beneficial effect of the utility model is: the utility model can make the car (cage) of stall tenesmus be clamped on the guide rail; Effectively prevented the safety misadventure of tenesmus; And owing to can effectively control the stop distance; Realize the elasticity stop, avoid the destructurized or gross distortion of car (cage) or guide rail bracket etc.Can effectively prevent the generation of safety misadventure, support personnel's personal safety.The utility model is simple in structure, safe and reliable, requires accuracy of manufacture not high, and cost of manufacture is low, and it is wide to adapt to range of use.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the constructional drawing front view of the utility model;
Fig. 2 is the constructional drawing birds-eye view of the utility model.
The specific embodiment
With reference to Fig. 1; A kind of progressive safety gear of anti-falling safety device; Comprise pincers seat 10, said pincers seat 10 1 ends are installed with slipper 2, and said pincers seat 10 other ends are provided with voussoir 13, voussoir guide rail 11, connecting rod 4, trigger mechanism 5, bearing seat 6, the tension spring 8 that is used to clamp; Rotatable fork 7 is installed on the said bearing seat 6; Said fork 7 one ends are captiveed joint with pincers seat 10 other ends through tension spring 8, and said fork 7 other ends are connected with voussoir 13 through connecting rod 4, and said trigger mechanism 5 is pressed on the fork 7.
Further, be provided with arc elastic leaf springs 12 in the said voussoir guide rail 11 as preferred embodiment.When car (cage) stop, arc elastic leaf springs 12 is by arc " 1 " font that just is compressed into.
Further, also be provided with adjustable bolt 9 between said tension spring 8 and the pincers seat 10 as preferred embodiment.
Further as preferred embodiment, said voussoir 13 is provided with first pad 14 that is used to increase friction force with the contact surface of guide rail.
Further as preferred embodiment, said slipper 2 is provided with second pad 3 that is used to increase friction force with the contact surface of guide rail.
Further, be provided with pressure spring 1 between said slipper 2 and the pincers seat 10 as preferred embodiment.
Further as preferred embodiment, said safety tongs is monolateral wedge shape, wedge shape guide rail clamping structure,
Or bilateral wedge shape, wedge shape guide rail clamping structure.
Design adds arc elastic leaf springs, two kinds of elastic components of pressure spring in pincers seats, and voussoir has adjustable bolt to carry out the starting force adjustment when embedding the pincers seat, leans on the size of adjustable bolt adjustment spring tension to obtain satisfied stopping distance.
Like Fig. 1, when car or cage were in normal running velocity, trigger mechanism 5 was pushed down fork 7, and voussoir 13 is in discontiguous state with the operation guide rail of slipper 2 relative cars or cage; When car or cage are in unusual stall and fall; Trigger mechanism 5 can be triggered and up move; Fork 7 is clickwise under the tension of tension spring 8; Fork 7 lifts voussoir 13 motion toward the upper left side in voussoir guide rail 11 through connecting rod 4, clamps the operation guide rail of car or cage with slipper 2, thereby reaches the function of braking.In the process of this braking, tension spring 8, arc elastic leaf springs 12, pressure spring 1 play good buffer action jointly, make anti-falling safety device can reach the technique effect that gradual elasticity clamps the operation guide rail.
More than be that preferable enforcement to the utility model specifies; But the utility model is created and is not limited to said embodiment; Those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
