Air cylinder clamping mechanism and air cylinder air volume sensor using the same

Abstract

The invention relates to an air cylinder clamping mechanism and an air cylinder air volume sensor using the same. The air cylinder clamping mechanism comprises two clamping bodies cooperating with a tested air cylinder. The two clamping bodies hinged to each other are used for respectively carrying a magnetic driving detecting assembly and a permanent magnet assembly; pitching type adjusting basesare arranged on the two clamping bodies to install the magnetic driving detecting assembly and the permanent magnet assembly respectively; pitching swinging axes of the adjusting bases are parallel with or overlapped with hinging axes of the two clamping bodies. Locking assemblies are arranged between the adjusting bases and the corresponding clamping bodies. The magnetic driving detecting assembly and the permanent magnet assembly are arranged at the corresponding clamping bodies by the adjusting bases; and the initial positions of the magnetic driving detecting assembly and the permanent magnet assembly on the clamping bodies can be adjusted, so that the adjustable range of the initial distance between the magnetic driving detecting assembly and the permanent magnet assembly is large. Therefore, the cylinder dimension range of the adaptive air cylinder is large.

Description

technical field [0001] The invention relates to an air duct clamping mechanism and an air duct air volume sensor using the same. Background technique [0002] The air duct air volume sensor, also known as the air duct status sensor, is a sensor used to monitor the working status of the colloidal air duct in the coal mine tunneling face. The air duct air flow sensor is usually composed of three parts: a magnetic drive detection assembly (including a reed switch assembly or a Hall unit), a permanent magnet assembly, and an air duct clamping mechanism. Wherein the main components of the blower clamping mechanism include a first clamping body and a second clamping body which are hinged to each other. When in use, the assembled magnetic drive detection component is connected to the first clip body, the permanent magnet assembly is connected to the second clip body, and the two clip bodies clamp the air duct. [0003] When the local fan stops running or there is no wind in the a...
