Elevator provided with safety loop detecting system and manual rescuing device

Abstract

The invention relates to an elevator provided with a safety loop detecting system and a manual rescuing device. The elevator overcomes the defects in the prior art. According to the key points of thetechnology, the elevator comprises the manual rescuing device. The end portion of a traction rope is wound around the manual rescuing device. When rescuing is needed, the wound traction rope can be released to achieve the elevator level. The safety loop detecting system comprises a safety loop and a plurality of switch detecting modules, wherein the safety loop comprises main switches, a pluralityof limiting switches and a plurality of safety switches, a power source is connected with a main safety contact coil through the safety loop, and each switch detecting module corresponds to one mainswitch, one limiting switch or one safety switch. The output ends of the switch detecting modules are in communicating connection with a host control system through a safety bus. The first detecting ends of the switch detecting modules are connected with movable contacts of the main switches, the limiting switches or the safety switches. The second detecting ends of the switch detecting modules are connected with static contacts of the main switches, the limiting switches or the safety switches.

Description

technical field [0001] The invention relates to a traction device, in particular to an elevator equipped with a safety circuit detection system and a manual rescue device. Background technique [0002] In high-rise buildings, in order to adapt to the needs of height changes, lifting devices are a necessary supporting equipment, such as elevators, which can bring great convenience to users. [0003] An elevator is a vertical elevator powered by a motor, also known as a vertical elevator. The vertical elevator is equipped with a box-shaped gondola, which is used for multi-storey buildings to take people or carry goods. From the earliest first-step safety elevator to the modern automatic control elevator, although it has been developed for hundreds of years, most of the elevators are driven by a traction drive mechanism, including a traction machine set on the top of the hoistway. The traction machine is connected to the traction wheel, and there is a traction rope on the tra...

AI Technical Summary

Problems solved by technology

[0007] The present invention solves the defects that the existing elevator performs emergency braking through the brake, and the car cannot be braked quickly due to the insufficient holding force of the brake, the braking reliability is low, and the safety of the elevator is not high. It provides a An elevator equipped with a safety circuit detection system and a manual rescue device, which can quickly brake when the elevator system fails, and directly locks and brakes through a traction wheel locking method, with high braking reliability and energy Effectively avoid safety accidents where the car jumps to the top or squats to the bottom

[0008] The present invention also solves the defects that the existing elevator cannot save itself and needs an external professional rescue team to rescue, the waiting time in the car is long, and it is easy to lose the first rescue time. It provides a safety loop detection system and manual rescue. The elevator with the device has a manual rescue device, which can be rescued by passengers in the car, winning the first rescue time and improving the safety of the elevator
