Abstract

The invention belongs to the technical field and discloses a braking system of a pedal elevator, which includes a car and a safety gear arranged outside the car, and also includes a pedal connecting rod, one end of which is hinged with the car, and a There are pedals; the tail connecting rod, one end of the tail connecting rod is hinged with the car; the middle connecting rod, one end of the middle connecting rod is hinged with the free end of the pedal connecting rod, and the other end of the middle connecting rod is hinged with the free end of the tail connecting rod; the middle hydraulic cylinder, The cylinder body of the middle hydraulic cylinder is hinged to the car, and the piston rod of the middle hydraulic cylinder is hinged to the connecting rod at the tail; the brake hydraulic cylinder, the brake hydraulic cylinder body is set outside the car, the brake hydraulic cylinder piston rod and the safety gear The starting part is connected, the brake hydraulic cylinder and the middle hydraulic cylinder are connected to each other through the oil pipe, and the piston rod of the brake hydraulic cylinder is stretched out to drive the safety gear to clamp the guide rail. Through the above technical solution, the problems of cumbersome actions and difficult operation in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of elevator braking, and in particular relates to a pedal elevator braking system. Background technique [0002] With the increase of high-rise buildings and the increasing height of buildings, elevators are used more and more widely. At the same time, elevator users also put forward strict requirements on the safety of elevators. The braking performance of elevators directly determines the overall safety of elevators. Currently , there is a passive elevator braking system on the market, although a passive elevator braking system is installed on the elevator. However, out-of-control phenomena such as the elevator's sliding car, rushing to the top, and bottom of the pier occur from time to time, which requires an active braking system to be installed in the car. Although some active braking systems have also appeared on the market, they still have defects and the use effect is not ideal. [0003] For exampl...
