Vibration prevention type centrifugal speed limiter and mining locomotive

Abstract

The invention discloses a vibration prevention type centrifugal speed limiter which comprises a casing, a sliding shaft and a rotating shaft, wherein the sliding shaft is arranged in the casing and parallel to the bottom end of the casing; a sliding shaft sliding outlet is formed in the side wall of the casing, one end of the rotating shaft is fixedly connected with the bottom end of the casing, and the other end is located on the outer side of the casing and connected with a drive part; a static slider and a movable slider are symmetrically distributed on the sliding shaft, springs are arranged between the movable slider and the side wall of the casing as well as between the static slider and the side wall of the casing; the vibration prevention type centrifugal speed limiter further comprises a first damper and a second damper, the first damper is connected with the movable slider through a first pull rod, and the second damper is connected with the static slider through a second pull rod. The invention further provides a mining locomotive based on the vibration prevention type centrifugal speed limiter. The vibration prevention type centrifugal speed limiter is simple in structure and high in practicability, and reduces vibration influence on a brake process.

Description

technical field [0001] The invention belongs to the field of mining mechanical equipment, in particular to an anti-vibration centrifugal speed governor and a mining locomotive. Background technique [0002] At present, the domestic man-made vehicles used by mine inclined shafts to transport workers up and down, whether they are claw type or holding rail type, are equipped with broken rope braking and manual braking protection, but there is no overspeed braking protection device. When the winch is out of control or other reasons cause people and vehicles to run with ropes, neither of these two brake protections can effectively play their role, which brings great safety hazards to mine inclined shaft operators. Therefore, a reliable limit The speed device has become the guarantee for the safe operation of mining locomotives. The existing speed limiting devices are electronic and mechanical: the structure of the electronic speed limiter is complex, the dependence on external a...
