Abstract
The utility model discloses a gravity balancing device of a brake bar of a gate. The gravity balancing device comprises a motor, a motor main shaft, a motor main shaft iron ring, the brake bar, a brake, an electromagnet and a brake pad, wherein the motor main shaft is connected with the motor main shaft iron ring; the surface of the brake pad is contacted with the surface of the motor main shaft iron ring; the brake can control the electromagnet; and after the electromagnet is electrified, push force can be generated to the brake pad. According to the gravity balancing device disclosed by the utility model, the defects of the existing gravity balancing device of the brake bar of the gate can be overcome so that the structure is more compact and the work is more reliable; and a transmission mechanism detection block of the brake can simulate a movement track of the brake bar and push force can be generated to the brake pad by the electromagnet, so that a direct proportion can be formed by a friction moment generated by contacting the brake pad with the motor main shaft iron ring, and an inverted moment generated by the gravity of the brake bar. Therefore, rebound force caused by that the brake bar falls down to a lower stopping point can be effectively prevented and the brake bar is more stable when being ascended and descended to a vertical position and a horizontal position.
Description
Technical field
The utility model relates to a kind of parking lot banister, and is particularly a kind of more steady when making restrictor bar be elevated to vertical position and horizontal level, thus the gravity balance device of shake when preventing that restrictor bar from falling.
Background technology
At present in the occasion that automobile is managed or charges, locate to be equipped with banister as parking lot, access, residential quarters etc., banister is let pass by the control vehicle that rises and falls of restrictor bar, the rising and falling then by driving mechanisms control of restrictor bar.Existing restrictor bar driving mechanism all is to reach the restrictor bar that links to each other with reducer output shaft by motor and the worm reducer that is attached thereto to constitute basically, and in the existing mechanism, on the restrictor bar axle, be connected with two tension springs usually, be used for the active force of restrictor bar is cushioned and balance.Though tension spring can play balanced action, need just can work than long tension spring, thereby it is bigger to take up room, and extension spring is easy to generate fatigue and pulling force is weakened.When reducing gear was gear mechanism, restrictor bar can produce a bounce that makes progress when lower dead center, made restrictor bar occur beating.Existing restrictor bar mechanism must unclamp arrangement of clutch earlier under power-off condition in addition, the lifting of ability manual operation restrictor bar, so troublesome poeration.
Summary of the invention
The utility model is intended to address the above problem, and more steadily reliable gravity balance device of a kind of compact conformation, work is provided.
Dismantled and assembled structure of the present utility model realizes by following scheme:
A kind of gravity balance device of restrictor bar, comprise motor, electric machine main shaft, electric machine main shaft iron ring, restrictor bar, brake, electromagnet and brake block, it is characterized in that, be connected with the electric machine main shaft iron ring on the described electric machine main shaft, the brake block surface contacts with electric machine main shaft iron ring surface, brake can be controlled electromagnet, can produce thrust to brake block after the electromagnet energising, rotates thereby hinder motor.
Described brake comprises that transmission mechanism, transmission mechanism main shaft, transmission mechanism main shaft detect piece and sense switch.
Described transmission mechanism detects piece and is installed on the transmission mechanism main shaft, and transmission mechanism detects the movement locus of piece and the movement locus of restrictor bar keeps synchronously.
Described sense switch can detect the movement position that transmission mechanism detects piece, and gathers signal and give brake.
Described brake block contacts the moment of friction that produces and is directly proportional with the opposing torque that the gravity of described restrictor bar produces with the electric machine main shaft iron ring.
The utility model has overcome the defective of existing restrictor bar balanced controls, make structure compacter, it is more reliable to work, detect the movement locus of piece simulation restrictor bar by the transmission mechanism of brake, make electromagnet produce a thrust to brake block, thereby the moment of friction that makes brake block contact generation with the electric machine main shaft iron ring is directly proportional with the opposing torque that the gravity of described restrictor bar produces.Thereby can effectively prevent the bounce of restrictor bar when dropping to lower dead center, more steady when making it be elevated to vertical position and horizontal level.

The structure enlarged drawing of the brake of the gravity balance device that Fig. 3 provides for the utility model.
The specific embodiment
Referring to Fig. 1, Fig. 2, this utility model comprises motor 1, electric machine main shaft 2, electric machine main shaft iron ring 3, restrictor bar 4, brake 5, electromagnet 6 and brake block 7, it is characterized in that, be connected with electric machine main shaft iron ring 3 on the described electric machine main shaft 2, brake block 7 surfaces contact with electric machine main shaft iron ring 3 surfaces, brake 5 can be controlled electromagnet 6, can produce thrust to brake block 7 after electromagnet 6 energisings.
This utility model is in the middle of specific implementation process, the rotational frequency of the transmission mechanism main shaft 52 of brake 5 is directly proportional with the rotational frequency of the electric machine main shaft 2 of motor 1, and the transmission mechanism main shaft on the transmission mechanism main shaft 52 detects the movement locus that piece 53 can be used to simulate the restrictor bar 4 on the transmission mechanism main shaft 52.Sense switch 54 gathers the positional information that detected transmission mechanism main shaft detects piece 53 to brake 5, and whether whether brake 5 realize controlling electromagnet 6 to brake block 7 generation thrusts by the energising of control electromagnet 6.Thereby the moment of friction that makes brake block 7 contact generation with electric machine main shaft iron ring 3 is directly proportional with the opposing torque that the gravity of restrictor bar 4 produces.The restrictor bar 4 of having offset after the gravity torque just can normal lifting under the normal operation of motor 1, and bounce-back and shake can not take place, and makes operation more steadily and reliable.
The utility model has overcome the defective of existing restrictor bar balanced controls, make structure compacter, it is more reliable to work, detect the movement locus of piece simulation restrictor bar by the transmission mechanism of brake, make electromagnet produce a thrust to brake block, thereby the moment of friction that makes brake block contact generation with the electric machine main shaft iron ring is directly proportional with the opposing torque that the gravity of described restrictor bar produces.Thereby can effectively prevent the bounce of restrictor bar when dropping to lower dead center, more steady when making it be elevated to vertical position and horizontal level.
The utility model is not limited to above-described embodiment; on the basis of the disclosed technical scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in protection domain of the present utility model.
