Background technique
When elevator exceeds the speed limit because of unexpected, elevator car safety brakes carriage or counterweight, in elevator chinese national standard
In, it is desirable that be loaded with rated load carriage or to average retardation rate when focusing on braking be 0.2g~1.0g, but it is known that peace
The brake force of full device be not it is constant, brake force is related to coefficient of friction, normal pressure.General progressive safety device passes through bullet
Property element to braking member apply normal pressure, braking member and rail friction generate brake force, but coefficient of friction and speed phase
It closes, in general, with the reduction of speed, coefficient of friction increases.Therefore during carriage braking, as carriage is made
Dynamic, speed is smaller and smaller, and coefficient of friction is increasing, and in the case where normal pressure is constant, brake force is increasing, braking deceleration
Degree is also increasing, and maximum deceleration can achieve 2~3 times of average retardation rate sometimes.Excessive deceleration can not only be multiplied
Visitor brings discomfort, or even generates unexpected injury, and can bring difficulty to the design of safety device, to guarantee safety, sedan-chair
Compartment component and safety device must be designed according to maximum weighted, thus make the ratio of elevator design cumbersome, higher cost, together
When initially adjustment setting brake force when relationship between average retardation rate and maximum deceleration must be taken into consideration, meet in national standard
Requirement for average retardation rate, this just brings very big difficulty to designer, it is necessary to be closed by largely testing to find
Suitable setting method needs to put into a large amount of manpower and material resources.
In existing security device technology, brake body is pressed the sliding on guide rail and generates brake force, braking by elastomer
Normal pressure on body is invariable, but when causing coefficient of friction to change due to carriage or counterweight velocity variations, brake force
It can only can not be adjusted with variation.Or must be by the way of complicated when being adjusted, such as patent
A kind of method that adjustment mode uses hydraulic control disclosed in CN01139661.X, structure is complicated.
Chinese Patent Application No. CN201510537341.7 discloses a kind of adjust automatically brake force device, elastomer point
For the first elastic element and the second elastic element, the elastic force that the second elastic element generates corresponds to brake force, the first elasticity member
The elastic force that part generates corresponds to the normal pressure of brake body, the second elastic element is compressed when brake force increases, while by anti-
Reduce the deformation of the first elastic element to voussoir, that is, reduce the normal pressure of brake body, so that brake force be made to keep constant.
The difficult point of the program is that the second elastic element is necessarily designed to negative stiffness, is difficult to realize in the existing structure.
Chinese Patent Application No. 201410286334.X discloses a kind of emergency braking apparatus of elevator, and elastomer is by more
A elastomer composition, elastic force releases device can release the elasticity of necessary amount in multiple elastomers when brake force becomes larger
Pressing of the body to brake body reduces brake force by reducing pressing force.In order to smooth adjustment in a big way, it is necessary to
Elastomer is divided into multistage, otherwise the adjustment of brake force can only just carry out limited adjustment, and cannot continuously adjust.Segmentation
Elastomer also increases the complexity of processing and manufacture, and is not applied for the safety dress of disk spring, helical spring mode
It sets.

2 lower end of brake body is fixedly connected with the connector 21 visited to 6 lower section of adjusting wedge；
It is provided at the correspondence of the connector 21 adjusting wedge 6 and adjusts screw 23；
The height for adjusting 23 upper end of screw is adjustable.
Preferably, as shown in Figure 1 and Figure 6, when 2 original state of brake body (elevator car safety is not operating), adjusting wedge 6
It is contacted and can be horizontally slipped on adjusting screw 23 with adjusting screw 23 by gravity or other external force such as spring force, adjust wedge
The adjusting vertical plane 6a of block 6 has gap between guide way 3.Action process is as follows: carriage 92 or 93 downlink of counterweight are because of unexpected speed
Degree increase, more than limiter of speed 94 setting value when, limiter of speed 94 act, lift wirerope 95, and then by actuating strut 96 and even
Extension bar 97 lifts brake body 2, and brake body 2 rises, and the working face of braking vertical plane 2a contact guide rail 91, brake body 2 is due to friction
The effect of power continues up, and due to wedge shape, makes guide way 3 to the first elastomer of long-range guided missile trackside motion compresses 4, the
Elastic force gradually increases after one elastomer 4 is pressurized, so brake body 2 and the pressure of guide rail 91 are also continuously increased, to make to brake
Power increases；When brake body 2 rises, adjusting wedge 6 is moved upwardly together, since the angle beta of 6 adjustable inclined surface apparatus 6b of adjusting wedge is big
The angle [alpha] of inclined-plane 2b, when rising same distance, lateral distance ratio of the adjusting wedge 6 far from guide rail are braked in brake body 2
Lateral distance of the guide way 3 far from guide rail is big, and the gap between adjusting vertical plane 6a and the guide way 3 of adjusting wedge 3 is got over
Next smaller, when gap is 0, brake force is exactly setting value, and is kept constant, and the movement of brake body 2 stops.Hereafter if braking
Power increases for some reason, and brake body 2 moves upwards, and adjusting screw 23 will push adjusting wedge 6 to move upwardly together, thus
First makes the normal pressure of elastomer 4 be transmitted to frame 1 by adjusting wedge 6, limit voussoir 5, between brake body 2 and guide rail 91
Normal pressure disappears, and is pushed under the active force for adjusting screw 23 in adjusting wedge 6, and brake body 2 is again back to contacting with guide rail 91
State generates suitable brake force.
Preferably, 6 upper end of adjusting wedge is suspended on described by the second elastomer 40 as shown in Fig. 1 and Fig. 4, Fig. 5
The top frame of frame 1, and the pulling force provided by the second elastomer 40, make the adjustable inclined surface apparatus 6b of adjusting wedge 6 be tightly attached to institute always
The limit inclined-plane for stating limit voussoir 5, is attached to the adjusting vertical plane 6a of adjusting wedge 6 on guide way 3, and at the beginning of brake body 2
When beginning state (elevator car safety is not operating), adjusting wedge 6 is not contacted with screw 23 is adjusted.Action process is as follows: carriage 92
Or 93 downlink of counterweight increases because of unexpected speed, more than limiter of speed 94 setting value when, limiter of speed 94 acts, lift wirerope 95,
And then brake body 2 is lifted by actuating strut 96 and connecting rod 97, brake body 2 rises, the work of braking vertical plane 2a contact guide rail 91
Make face, brake body 2 is since the effect of frictional force continues up, and due to wedge shape, transports guide way 3 to long-range guided missile trackside
Dynamic pressure the first elastomer 4 of contracting, elastic force gradually increases after the first elastomer 4 is pressurized, so the pressure of brake body 2 and guide rail 91
It is continuously increased, so that brake force be made to increase, adjusting wedge 6 is mobile to long-range guided missile trackside due to guide way 3, in the second elastomer 40
Under the action of move up, but always be close to guide way 2 and limit voussoir 5.Since the angle beta of 6 adjustable inclined surface apparatus 6b of adjusting wedge is greater than
Brake body 2 brakes the angle [alpha] of inclined-plane 2b, so brake body 2 is upward in the case where generating the lateral displacement of identical separate guide rail
Mobile displacement is big, and the upward displacement of adjusting wedge 6 is small, so adjusting the distance between screw 23 and adjusting wedge 6 increasingly
It is small.When adjusting the distance between screw 23 and adjusting wedge 6 is 0, brake force reaches setting value, and keeps constant, brake body 2
Movement stop.Hereafter if brake force increases for some reason, brake body 2 is moved upwards, and tune will be pushed by adjusting screw 23
Section voussoir 6 moves upwardly together, so that the normal pressure of the first elastomer 4 be made to be transmitted to frame by adjusting wedge 6, limit voussoir 5
Frame 1, the normal pressure between brake body 2 and guide rail 91 disappear, and are pushed under the active force for adjusting screw 23 in adjusting wedge 6, braking
Body 2 back to the state contacted with guide rail 91, generates suitable brake force again.Adjusting wedge 6 and adjust screw 23 between away from
From that can be adjusted by adjusting screw 23, different distances can correspond to different setting power, change this distance
The climb for controlling brake body 2, to control the size of brake force and braking deceleration.
