Description
Technical field
The utility model is related to the technical field of elevator, especially a kind of elevators using unidirectional progressive safety gear.
Background technology
An important safety component of the elevator safety gear as elevator, is the indispensable important component of elevator.Elevator
Safety tongs is divided into instantaneous formula and gradual two types.
The action of safety tongs device is so that rope-clamping pliers is clamped governor rope by limiter of speed action, as car is transported downwards
Row, governor rope lift safety tongs link mechanism, and the action of safety tongs link mechanism drives safety tongs braking member to be connect with guide rail
It touches, so that the safety tongs on guide rail both sides is simultaneously clamped on guide rail, reach car stop.
When elevator speed is more than 1.15 times of normal speeds, elevator governor action is pulled by speed limiter wire rope
Safety tongs pulling apparatus on car makes the safety tongs of car both sides act, and safety tongs tightly vises guide rail, to make sedan-chair
It brakes in compartment.Safety tongs is a brake apparatus, is mounted on lift car or elevator counterweight bottom.It include shift mechanism and
Arrestment mechanism two parts.The effect of shift mechanism is that the mechanical action of limiter of speed is transmitted to arrestment mechanism and arrestment mechanism is made to move
Make, elevator can be stuck on guide rail by its internal wedge block after arrestment mechanism action avoids elevator from further falling.
Safety tongs is typically mounted on car bottom girder or two heel posts, current progressive safety gear, is symmetrical mostly
, it needs two symmetrical branches of voussoir, and acts simultaneously, and main problem is existing for this structure, complicated, volume compared with
Greatly, cumbersome for installation, cost is higher, and active force can not accomplish complete equipilibrium.Since safe wrench structure is complex, lead to its warp
It often is easy to happen failure, failure cause is complicated and changeable, and the factor for inspiring its malfunction is also more, therefore there are certain safety
Hidden danger, it is possible to have serious consequences to elevator and passenger.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of simple in structure, uses that can prevent lift car from falling
The elevator of unidirectional progressive safety gear.
In order to solve the above technical problems, the elevator provided by the utility model using unidirectional progressive safety gear, this is unidirectional
Progressive safety gear includes：Caliper equipped with breaker slot, which is set to the front end face of the caliper, by the top surface of the caliper
It is obliquely extended to the bottom surface of caliper, the both sides of breaker slot are divided into left caliper, right caliper body, so that on the left caliper under width
Narrow, the described up-narrow and down-wide setting of right caliper body, the side wall of the right caliper body are fixedly connected with the friction plate being vertically arranged, the friction plate
Damping spring is arranged in top, to carry out damping to friction plate；Further include and the matched voussoir of the left caliper, the voussoir band
Bevelled side contacts and is slidably matched with the oblique side wall of left caliper, and the oblique side wall setting guiding of the left caliper is convex
Guiding groove compatible with the guiding projection is arranged in block, the inclined-plane side of the voussoir, so that voussoir and left caliper is oblique
It is oriented to when snug engagement, avoids crooked in voussoir sliding process, influence braking effect；The inclined-plane of the voussoir is led
Polytetrafluorethylecoatings coatings are coated to the surface of groove, the oblique sidewall surfaces of the right caliper body, guiding projection surface, to increase wedge
Lubricity between block and right caliper body；The top of the voussoir is hinged a pull rod, which is connected with the pulling apparatus of elevator, uses
In pulling voussoir upward sliding；When assembly, elevator brake guide rail is placed in breaker slot, and the speed that lift car declines is more than setting
When value, pulling apparatus action pulls pull rod, voussoir upward sliding simultaneously to elevator brake guide rail displacement, until voussoir and elevator
Braking guide rail contact is simultaneously stuck, and lift car is static.
Further, the guiding projection is in semi-cylindrical, and the guiding groove is to be adapted with semi-cylindrical guiding projection
Arcuate guide groove, so as to guiding projection and be oriented to groove and obtain better sliding effect.
Further, the friction plate is connected through bolt with the right caliper body, convenient for according to the width pair of elevator brake guide rail
Friction plate is adjusted, to adapt to the demand of different elevator brake guide rails.
The technique effect of utility model：（1）The unidirectional progressive safety gear that the elevator of the utility model uses, relative to existing
There is technology, is matched and braked using voussoir and breaker slot, it is simple in structure；（2）By guiding projection and it is oriented to recess
It closes, the sliding of voussoir is guided, occur in avoiding voussoir from sliding crooked；（3）The inclined-plane of voussoir, the oblique side wall of left caliper
Surface coats polytetrafluorethylecoatings coatings, increases lubricity, while antirust, prolongs the service life.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings of the specification：
Fig. 1 is the dimensional structure diagram of the utility model；
