Abstract

The high-safety mechanical speed-limiting elevator safety tongs comprise a top plate, side plates, connecting plates, a square plate, a tongs body and fixing nails, the two side plates arranged side by side are installed at the bottom of the top plate, the connecting plates are installed on the outer walls of the adjacent sides of the two side plates, and vertical plates are installed on the outer walls of the adjacent sides of the two connecting plates; a distance sensor is installed on the front face of the vertical plate, and an alarm is installed on the top of the top plate. Square plates are installed on the outer walls of the adjacent sides of the two sets of side plates. By arranging the distance monitoring device, when the distance between the guide rail and the distance sensor exceeds a set range, the alarm can make a set sound, distance data of the distance sensor can be transmitted to an elevator master control room, a tooth groove plate in the device has the disassembling and assembling functions, replacement is convenient, meanwhile, material resources can be saved, and when the device is braked, the device is convenient to disassemble and assemble. Impact can be relieved through the spring, the device has the movable dust blowing function, and it can be ensured that no dust is accumulated on the tooth groove plate.

Description

technical field [0001] The invention relates to the technical field of safety gears, in particular to a mechanical speed-limiting elevator safety gear with high safety. Background technique [0002] Elevators are commonly used transportation equipment, especially car elevators used in high-rise buildings, and the safety of elevators is becoming more and more important. Safety gear is an important part of the elevator safety system. The elevator safety gear device is in the speed limiter. Under control, when the elevator speed exceeds the speed limit set by the speed governor, or when the suspension rope breaks and loosens, it is a safety device that stops the car in an emergency and clamps it on the guide rail. [0003] The defects of the existing safety gear are: [0004] 1. The patent document CN207258947U discloses a two-way speed-limiting safety gear for an elevator, which "comprises a fixed guide rail, a frame body, an upper braking unit, a lower braking unit, a brakin...
