Abstract

The invention provides an electrical system controlling dynamic compactor full-release winding braking and a working method of the electrical system controlling dynamic compactor full-release winding braking. The electrical system controlling dynamic compactor full-release winding braking comprises a height collecting mechanism, a tension collecting mechanism, a hand-operated control switch, a programmable logic controller, an order output device, a display device, an actuator and a power supply unit. The electrical system controlling dynamic compactor full-release winding braking and the working method of the electrical system controlling dynamic compactor full-release winding braking have the advantages that the programmable logic controller is selected to serve as the core of a control system, existing devices on a dynamic compactor are used for effectively controlling braking opportunities of winding of the dynamic compactor under the condition that the cost of hardware of the electrical system is not increased, thus the purposes that the efficiency of a single time of ramming is improved, ropes are prevented from disorder during winding, and the working life of winding is prolonged are achieved, by means of cooperation between the programmable logic controller and a moment limiter when the programmable logic controller and the moment limiter are in use, timely and accurate braking of full-release winding can be ensured, cost can be reduced, and time needed by debugging is shortened.

Description

technical field [0001] The invention belongs to the technical field of construction machinery, and in particular relates to an electrical system and a working method for controlling the full-release winch brake of a dynamic compaction machine. Background technique [0002] In order to improve the work efficiency of the dynamic compaction machine, the full release winch is usually selected as the main lifting winch. The full release winch realizes the connection between the drum and the winch motor through the clutch. During normal lifting, the power of the output end of the winch motor acts on the reel through the clutch, and the reel provides traction for the wire rope wound on it to lift the heavy object. In the process of lowering the tamper, in order to improve the working efficiency of the dynamic tamping machine, the clutch separates the reel from the hoisting motor, and the reel freely lowers the wire rope under the action of the gravity of the rammer. [0003] The ...
