Elevator intercepting device

Abstract

The invention discloses an elevator intercepting device, which comprises a buffer assembly and a mandatory braking assembly; the buffer assembly is arranged at the bottom end of the car; The forced braking mechanism on the upper body, the forced braking mechanism includes a brake seat, a brake claw, a strong spring and an electromagnetic control valve. The brake claw is set corresponding to the position of the buffer component. One of the bottom corners is hingedly connected to the brake seat, and the other bottom corner is provided with a spring seat. The brake claw is also equipped with a buckle mechanism. One end of the strong spring is fixed on the brake seat, and the other end is against the On the spring seat of the brake dog, the solenoid-operated valve includes a solenoid-controlled telescoping bolt. The elevator intercepting device can effectively protect the lifting and lowering of the elevator when the elevator breaks a rope or runs out of speed, and can also play a protective role when the elevator is powered off.

Description

technical field [0001] The invention relates to an elevator intercepting device, in particular to a device suitable for intercepting an elevator in a broken rope or speeding state, and belongs to the field of elevator safety protection. Background technique [0002] With the development of society, the use of elevators has become more and more common. It has been used only in commercial buildings and hotels, and has been used in office buildings, residential buildings and other places. Vertical elevators are the most common. Popularity has brought convenience to people's lives, but the accompanying elevator accidents have gradually increased, and people have begun to pay more and more attention to the safety protection measures of vertical elevators. [0003] Vertical elevators generally include four spaces and eight systems. The four spaces include machine room, shaft and pit, car and landing. The eight systems generally include traction system, guidance system, car system,...

AI Technical Summary

Problems solved by technology

[0005] 1. The speed limiter of the traditional overspeed protection device is usually installed on the ground of the elevator machine room or the sound insulation layer, the tension wheel of the speed limiter rope is installed in the pit of the shaft, and the speed limiter rope is wound around the speed limiter wheel and the tension wheel It forms a fully closed loop, and its two ends are installed on the car frame through the rope end connecting frame to operate the lever system of the safety gear. , speed limiter rope broken or excessive slack so that the tensioning device loses its effect, etc.

[0006] 2. The traditional safety protection device can only function when there is mains power. Once the elevator is powered off, the device usually does not work. For example, the traditional broken rope and broken belt protection device is used in the transmission of the speed limiter steel wire rope and the tachogenerator. The belt and the steel belt of the layer selection and signal feedback device are equipped with broken rope and broken belt switch. Once the broken rope or broken belt occurs, the switch will act immediately, which can cut off the safety control circuit and force the elevator to stop running. In the case of broken rope and broken belt switch is usually unable to operate
