Abstract
The invention discloses an elevator speed limiting device mounted on an elevator car. The elevator speed limiting device mounted on the elevator car comprises two rope wheels. One rope wheel is provided with a centrifugal limiting device which is formed by connecting two centrifugal blocks and a steering device. The other rope wheel is used for guiding a rope. The two rope wheels are arranged on a supporting frame and fastened to a star-shaped piece provided with several claws, and the claws have a brake function and used for braking the centrifugal blocks when the actual speed exceeds a speed threshold value. An encoder is mounted on a wheel shaft of the rope wheels and used for tracing the position of the elevator car all the time, and position information of the elevator car cannot be lost even under the braked condition. The speed limiting device is mounted on the elevator car and transmits wedging force upwards and downwards, and before the rope slides to the position in front of the rope wheels, the braking action is executed while a wedging signal is transmitted to a safety device through an auxiliary rod. The elevator speed limiting device has the beneficial effects that space occupation is avoided, vibration is restrained, and the position information of the elevator car can be traced at any time.
Description
Technical field
The present invention relates to a kind of elevator speed governor, be specifically related to a kind of mounted elevator speed governor on the elevator car.
Background technology
Up to the present, commercially available elevator speed governor is all not mounted within lift car, and is mounted in elevator(lift) machine room, and this means that needs take up room.It addition, speed-limiting device is positioned at machine room so that the distance between speed-limiting device and safety device increases, needing to make at the other end of elevator hoistways to use guide block, the problem presented is to vibrate when upwards operating device, in addition also takes up hoistway space.Speed-limiting device is not connected with car, and owing to transmission is responsible for by rope itself, so not having actuating device between speed-limiting device and safety device, after only rope slides into rope sheave, safety device is the most wedged.Additionally, the wedging force of safety device is transmitted by rope self, once there is the situation of fracture in rope, and wedge shoe system does not receive signal, and can not wedge car, it will bring significant damage.
Summary of the invention
The technical problem to be solved in the present invention is to be arranged on car by speed-limiting device, it is to avoid use guide block, it is to avoid takies too much space, suppression vibration, follows the trail of car location information all the time.
In order to solve above-mentioned technical problem, the present invention uses the technical scheme to be: a kind of mounted elevator speed governor on the elevator car.
A kind of mounted elevator speed governor on the elevator car, including: two rope sheaves, wherein a rope sheave has centrifugal restriction device, two centrifugal-blocks connect and compose with transfer；Another rope sheave is used for guide cords；Two rope sheaves are placed on the support frame, and it fastens with the star-like part with some pawls, and pawl plays the effect of brake, for braking centrifugal-block when threshold velocity is exceeded.Installing an encoder on the wheel shaft of rope sheave, it follows the trail of the position of car all the time, even if the most not losing car location information in the case of braking.Described speed-limiting device is arranged on car, transmits wedging force in direction up and down, and before rope slides into rope sheave, while wedging signal passes to safety device by an auxiliary rod, restriction action occurs.
Described centrifugal-block is outward displacement when speed exceedes maximum threshold velocity, and one of them clashes into one of them pawl of star-like part, thus check band wheel rotates.
Installing an encoder on the wheel shaft of described rope sheave, it follows the trail of car position always, does not vibrates owing to the characteristic of rope sheave self neither rebounds, and improves the reliability of encoder reading.
The advantage that the invention solves the problems that and providing the benefit that: avoid speed-limiting device is arranged on machine room, avoid taking up room, avoid using guide block, wedging force is transmitted to safety device not in use by rope self, vibration is suppressed, and follows the trail of car location information all the time no matter being moved by encoder car or braking.

2a, rope sheave wheel shaft 5a, star-like part pawl.
Detailed description of the invention
The present invention will be further described below in conjunction with the accompanying drawings: a kind of mounted elevator speed governor on the elevator car, including: two rope sheaves (1,2), wherein a rope sheave (1) has centrifugal restriction device, two centrifugal-blocks (3) connect and compose with transfer；Another rope sheave (2) is used for guide cords；Two rope sheaves (1,2) are positioned in support frame (4), and it fastens with the star-like part (5) with some pawls (5a), and pawl (5a) plays the effect of brake, for braking centrifugal-block (3) when threshold velocity is exceeded.The wheel shaft (2a) of rope sheave (2) is upper installs an encoder, and it follows the trail of the position of car all the time, even if the most not losing car location information in the case of braking.Described speed-limiting device is arranged on car, transmits wedging force in direction up and down, and before rope slides into rope sheave, while wedging signal passes to safety device by an auxiliary rod, restriction action occurs.
Claims (3)
1. a mounted elevator speed governor on the elevator car, including: two rope sheaves (1,2), wherein a rope sheave (1) has centrifugal restriction device, two centrifugal-blocks (3) connect and compose with transfer；Another rope sheave (2) is used for guide cords；Two rope sheaves (1, 2) it is positioned in support frame (4), it fastens with the star-like part (5) with some pawls (5a), pawl (5a) plays the effect of brake, for braking centrifugal-block (3) when threshold velocity is exceeded, the wheel shaft (2a) of rope sheave (2) is upper installs an encoder, it follows the trail of the position of car all the time, even if the most not losing car location information in the case of braking, described speed-limiting device is arranged on car, wedging force is transmitted in direction up and down, before rope slides into rope sheave, while wedging signal passes to safety device by an auxiliary rod, restriction action occurs.
Mounted elevator speed governor on the elevator car the most according to claim 1, it is characterized in that: when speed exceedes maximum threshold velocity, centrifugal-block (3) outward displacement, one of them clashes into one of them pawl (5a) of star-like part (5), thus check band wheel rotates.
Mounted elevator speed governor on the elevator car the most according to claim 1, it is characterized in that: the wheel shaft (2a) of rope sheave (2) is upper installs an encoder, it follows the trail of car position always, do not vibrate owing to the characteristic of rope sheave (2) self neither rebounds, improve the reliability of encoder reading.
