Embodiment 1

[0013] Embodiment 1: In this embodiment, the telescopic piston is a hydraulic telescopic piston 4, and the pressure pipe and the power system correspond to the hydraulic oil pipe 5 and the hydraulic power system 7 respectively. In other embodiments, the telescopic piston can be a pneumatic telescopic piston, and the pressure tube and the power system correspond to the pneumatic tube and the pneumatic power system respectively. The front end of the fixed seat 3 is connected with the vehicle stop frame 2, and the rear end of the fixed seat 3 is connected with the telescopic piston.

[0014] The front end of the fixed seat 3 is rotatably connected to the frame 2, and the rear end of the fixed seat 3 is rotatably connected to the piston seat of the hydraulic telescopic piston 4. The piston rod of the hydraulic telescopic piston 4 is rotatably connected to the body of the frame 2. Other embodiments The rear end of the middle fixed seat 3 is rotatably connected to the piston rod of ...

Abstract

A normally closed cart stop for the slope shaft in mine or tunnel has a fixed base connected to top end of slope shaft, a stop frame connected to one end of said fixed base, a telescopic piston with one end linked to said fixed base and another end linked to the stop frame, a hydraulic or pneumatic power system and a control system. The lift of stop frame is controlled by said telescopic piston. Its advantage is high sensitivity and stability.

Description

technical field [0001] The invention relates to the technical field of safety devices in mines or tunnels, in particular to a normally closed car stopper for inclined mine shafts with a hydraulic telescopic control car stopper. Background technique [0002] At present, the structure of the domestic mine inclined shaft mechanical car stop is mainly connected by the car stop frame, the pulley and the hoisting winch wire rope. The pulley of the device wears a lot, and the wire rope connecting the frame is long, insensitive, and has a high failure rate, especially during the whole process of ascent or descent of the transport vehicle, the frame is in an open state, which cannot play a role in safety control; Although the prior art has been improved, such as the normally closed structure design, the application number 96228423, the title of invention is "Incline Lane Winch Interlock Normally Closed Automatic Car Barrier Device", which consists of winch interlock controller, suppo...
