Embodiment
As shown in figure 1, the present invention has the elevator 10 of elevator emergency brake device, including car 1, car 1 passes through rope 4
It is connected with the drive mechanism for being arranged on building top；T-shaped guide rail 2, sedan-chair are fixedly installed in the operation passage 20 of car 1
Railway carriage or compartment 1 is movably set in T-shaped guide rail 2, and car 1 can be run along T-shaped guide rail about 2；The upper and lower part of car 1
It is respectively arranged with guide 1a and 1b；
The bottom of car 1 is fixedly installed emergency braking apparatus 3, from emergency braking apparatus 3 is used for when the stall of car 1 is fallen
Braking action.
As shown in Fig. 2 emergency braking apparatus 3 includes braking voussoir 31, the back side of braking voussoir 31 is provided with guide 34,
The connection clamp block 35 of guide 34, pincers block 35 is fixedly connected with support frame 37 by elastomer 36；Support frame 37 and car 1
It is fixedly connected；Brake the lower end connection lifting rod 32 of voussoir 31；Guide 34 is used for the direction of motion for limiting braking voussoir 31；
Lifting rod 32 is used to promote braking voussoir 31 to move upwards relative to guide 34；Elastomer 36 can produce braking voussoir 31
The raw thrust to guide rail 2；
Braking voussoir 31 is arranged at the side of guide rail 2, brakes the braking surface (i.e. close to the front of guide rail 2) of voussoir 31 with leading
Had angle to shape between face (i.e. the back side away from guide rail 2), so that braking voussoir 31 is wedge shaped (to brake voussoir 31
Spigot surface is inclined-plane)；The braking surface for braking voussoir 31 is parallel with the side of guide rail 2, brakes the spigot surface and guide rail 2 of voussoir 31
Side between shape have angle；
Guide 34 is made up of the rolling element being arranged above and below, and the side of rolling element is contacted with pincers block 35, the opposite side of rolling element with
Braking voussoir 31 is contacted；
The contact surface for clamping block 35 and guide 34 is inclined-plane, and the angle of inclination on the inclined-plane is engaged with braking the spigot surface of voussoir 31,
To ensure that the braking surface of braking voussoir 31 is parallel with the side of guide rail 2.
Each side that emergency braking apparatus 3, i.e. guide rail 2 can be respectively arranged with the both sides of guide rail 2 is correspondingly arranged one respectively
Brake voussoir 31；One of side of emergency braking apparatus 3, i.e. guide rail 2 can also be only set to set in the side of guide rail 2
Brake voussoir 31.
The operation principle of emergency braking apparatus 3 is as follows：
Fig. 2 is schematic diagram of the emergency braking apparatus 3 under not operating state, now brake voussoir 31 braking surface and guide rail 2 it
Between there is gap；
When the speed that car 1 declines exceedes setting speed, the emergency braking apparatus 3 being fixedly connected with car 1 therewith it is quick to
Lower motion；I.e. support frame 37, pincers block 35 and braking voussoir 31 are relative to the sharp downward movement of guide rail 2；
Emergency braking apparatus 3 is triggered, and lifting rod 32 drives braking voussoir 31 along guide 34 relative to support frame 37
Motion (braking voussoir 31 still keeps down motion relative to guide rail 2), makes the gap between braking voussoir 31 and guide rail 2 upwards
It is progressively smaller until that braking voussoir 31 contacts with guide rail 2 and produces force of sliding friction；
Because braking voussoir 31 is moved downward relative to guide rail 2, the sliding friction force direction between braking voussoir 31 and guide rail 2
Upwards, the force of sliding friction continues up braking voussoir 31, until braking voussoir 31 touches framework upper plate 37a；
During this, force of sliding friction gradually increases, until the friction plate assembly 31b of the braking braking surface of voussoir 31 compresses guide rail 2, shape
Into brake force；The brake force passes to car 1 by the framework upper plate 37a of support frame 37, slows down so as to be realized to car 1
Braking.
Brake the brake force size that voussoir 31 produces depend on elastic force and braking voussoir 31 and guide rail 2 that elastomer 36 applies it
Between coefficient of friction.It is because the rigidity and decrement of elastomer 36 are easy to one of accurate adjustment, therefore factor of braking force fluctuation
Due to the fluctuation of the coefficient of friction between braking voussoir 31 and guide rail 2.The car 1 of high-speed cruising can be produced greatly in braking procedure
The heat of amount, forming stable temperature field between the friction plate 31b1 of braking voussoir 31 and the contact surface of guide rail 2 contributes to friction
The stabilization of coefficient.
As shown in figure 3, braking voussoir 31 includes voussoir support member 31a, voussoir support member 31a braking surface be fixedly installed to
A few friction plate assembly 31b.
As shown in figure 4, friction plate assembly 31b is fixedly connected with voussoir support member 31a by multiple machanical fastener 31c.
As shown in figure 5, friction plate assembly 31b includes being fixedly installed a friction plate on installing plate 31b1, installing plate 31b1
31b2.Friction plate 31b2 is resistant to elevated temperatures ceramic material, and friction plate 31b2 is fixed to installing plate 31b1 in the way of mechanically or chemically
Surface, to ensure the fixing assembling of ceramic material and metal material.
As shown in fig. 6, two friction plate 31b2 can also be fixedly installed on installing plate 31b1.
As shown in fig. 7, multiple friction plate 31b2 can also be fixedly installed on installing plate 31b1；Multiple friction plate 31b2 length
Degree and width can be different.
As shown in figure 8, friction plate 31b2 and the contact area S1 (S1=c × d) and installing plate 31b1 of guide rail 2 area S0
The ratio between (S0=a × b) is more than or equal to 0.55, and area is more conducive to the stabilization of coefficient of friction than bigger.
Preferably, the ratio between friction plate 31b2 and contact area S1 and installing plate 31b1 area S0 of guide rail 2 is more than or equal to
0.65。
The present embodiment is the situation for setting a friction plate 31b2 on installing plate 31b1 to the explanation of area, if installing plate
Multiple friction plate 31b2 are set on 31b1, then friction plate 31b2 and guide rail 2 contact area S1 refer to multiple friction plate 31b2
With the contact area sum of guide rail 2.
Preferably, two friction plates 31b2, each friction plate 31b2 are set on each friction plate assembly 31b installing plate 31b1
It is more than or equal to 0.325 with the ratio between contact area S1 and installing plate 31b1 the area S0 of guide rail 2.
After 3 trigger action of emergency braking apparatus, during the surface of ceramic friction plate 31b2 and guide rail 2 rubs,
In friction surface formation surface high-temp area, ceramic friction plate can bear 1000 DEG C of high temperature without failing, friction plate 31b2
Coefficient of friction between guide rail 2 is more stable, so as to reduce the fluctuation of deceleration in braking procedure.Further, since ceramic
Material has very high mechanical performance, friction plate 31b2 material property is ensure that in heavy duty braking, as a result of reasonable
Structure and assembling form, ensure that the integral stop performance of a whole set of braking equipment.
