Automatic traction device of coal charging train

Abstract

The invention discloses an automatic traction device of a coal charging train. The automatic traction device comprises the coal charging train and a coal loader located in a coal charging area; a variable-frequency traction winch used for pulling the coal charging train, a control module of the variable-frequency traction winch, a control signal module of the variable-frequency traction winch, a coal charging area detection module used for detecting whether the coal charging train is located in the coal charging area or not, and a weight measuring module of the coal charging train are included; the signal output end of the coal charging area detection module is connected with the signal input end of the control module; the signal output end of the control module is connected with the signal input ends of the variable-frequency traction winch and the coal loader through the control signal module, the variable-frequency traction winch is fixedly connected with the coal charging train through a twisted rope, and the weight measuring module is arranged at the bottom, located in the coal charging area, of the coal charging train; and the signal output end of the weight measuring module is connected with the signal input end of the control module, and the power input ends of the control module and the control signal module are both connected with a power source. According to the scheme, coal charging automation is achieved, and economic benefits and safety are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of coal transportation in coal mines, and more specifically, the invention relates to an automatic traction device for a coal-loading train. Background technique [0002] Nowadays, in the coal bunker loading system on the ground, it uses a single-point loading dustpan loading under the belt under the bunker, and each dispatching winch can be rated to pull 26 sections of train skins. With the continuous improvement of coal blending and loading standards for truck loading, premature fatigue damage occurred in the steel wire rope, and the replacement and reconstruction process was also complicated. The traction speed fluctuated from fast to slow, and it was difficult to control. The limit switch of the traction winch does not have a real locking effect, and there are many safety hazards in the counterweight of the tensioning device and the iron tower. And non-frequency conversion traction winch traction, the s...

Problems solved by technology

With the continuous improvement of coal blending and loading standards for truck loading, the steel wire rope has premature fatigue damage, and the replacement and reconstruction process is also complicated. The traction speed is fast and slow, and it is not easy to control.

The limit switch of the traction winch does not have a real locking effect, and there are many safety hazards in the counterweight of the tensioning device and the iron tower

And non-frequency conversion traction winch traction, the speed is not easy to control, frequent start and stop will cause great damage to the traction winch, and also have a great impact on the power grid
