Tramcar derailing preventer for mine inclined shafts

Abstract

The invention discloses a tramcar derailing preventer for mine inclined shafts and belongs to the technical field of tramcar derailing prevention for inclined shafts. The tramcar derailing preventer for mine inclined shafts comprises a winch and an arrester. The winch is connected with a rotary encoder. The arrester driven by an oil cylinder comprises a mesh curtain and wire ropes. The rotary encoder is connected with the oil cylinder through an electric cabinet. The electric cabinet is connected with a PLC (programmable logic controller) module. Buffers are symmetrically arranged on the inner side of a rail below the oil cylinder and are connected with the arrester through the wire ropes. A car stopper is disposed on the inner side of the rail between the winch and the electric cabinet and is connected with the electric cabinet. Both the winch and the oil cylinder are driven by a motor. The tramcar derailing preventer for mine inclined shafts has the advantages that the travel of the oil cylinder is reduced, opening-closing time of the arrester is shortened, work efficiency is improved, joint locking is achieved, the arrester closes and opens automatically, blocking effect is ensured, derailing hazard is reduced, and the tramcar derailing preventer for mine inclined shafts is easy to maintain and suitable for application in production operations.

Description

technical field [0001] The invention relates to an anti-car device, in particular to an anti-car device for a mine-used inclined shaft. Background technique [0002] Inclined shaft anti-running device is an important safety equipment for the lifting and transportation of inclined shafts in coal mines. It is installed in the inclined shafts of coal mines. If the car runs due to broken ropes, decoupling and other reasons, flexible buffers can be used to achieve effective interception. [0003] Traditional anti-car devices for inclined shafts in mines mainly include pneumatic anti-car devices and electric anti-car devices. Pneumatic anti-car devices realize the opening and closing of the barrier through the expansion and contraction of cylinders. However, the air supply pipeline is long and the air source is insufficient. The pressure does not meet the requirements; the electric anti-sports device drives the winch through the positive and negative rotation of the motor to reali...

[0003] Traditional anti-car devices for inclined shafts in mines mainly include pneumatic anti-car devices and electric anti-car devices. Pneumatic anti-car devices realize the opening and closing of the barrier through the expansion and contraction of cylinders. However, the air supply pipeline is long and the air source is insufficient. The pressure does not meet the requirements; the electric anti-sports device drives the winch through the positive and negative rotation of the motor to realize the opening and closing of the barrier. However, the electric anti-sports device is bulky, heavy and inconvenient to install
