Lift car buffering device for elevator shaft

Abstract

The invention discloses a lift car buffering device for an elevator shaft. The lift car buffering device for the elevator shaft comprises a first mounting plate, wherein two sides of the bottom end ofthe first mounting plate are movably connected with the top ends of telescopic rods welded at the upper end and the lower end of a deep well close to two sides of the middle portion; the middle portion of the upper end of the first mounting plate is in threaded connection with a mounting frame through a connecting rod; the middle portion of the top of the mounting frame is penetratingly connectedwith a first thrust plate through a vertical rod; the middle portion of the upper end of a second mounting plate is in threaded connection with a damping frame; a shell is arranged in the middle of the inner bottom end of the damping frame; a piston rod is movably connected to the upper end of the shell and extends into an oil cavity arranged in the middle of the inner portion of the shell; a second thrust plate is fixedly connected to the upper end of the piston rod; and a damping spring sleeves outside the piston rod. By arranging a first infrared distance measuring sensor, a second infrared distance measuring sensor, a buffering spring, the damping spring, the oil cavity, the piston rod and a telescopic rod structure, the lift car buffering device for the elevator shaft has advantagesof improving the buffering performance of a lift car body and being convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of elevator equipment, in particular to a car buffer device for an elevator shaft. Background technique [0002] The elevator is a vertical lifting mechanism powered by a motor, and is equipped with a box-like gondola. The car runs on at least two rows of rigid rails that are perpendicular to the horizontal plane or have an inclination angle of less than 15° from the plumb line. Permanent transportation The equipment also has a step type. The tread plate is installed on the crawler belt and runs continuously. It is commonly known as an escalator or moving walk. It serves as a fixed lifting equipment for a specified floor. A buffer device is installed inside the well, which will effectively reduce casualties. [0003] But there is following deficiency in prior art: [0004] 1. During the operation of the car, there is no buffer device installed inside the elevator shaft, or the effect of the buffer device i...
