Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the plan structure scheme drawing of Fig. 1;
Among the figure be: torque motor 1, bell-jar 2, wet friction sheet drg 3, reductor 4, winch 6, cylinder 5, steel rope 7, frame 8.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done further explanation:
Like Fig. 1, shown in Figure 2; The extension band type conveyor kinetic control system; Comprise PLC controller, frequency converter, torque motor 1, coder; It is characterized in that: the PLC controller is fixed on the torque motor 1 on the frame 8 through Frequency Converter Control, and the output shaft of torque motor 1 is connected with wet friction sheet drg 3 through coupler; Wet friction sheet drg 3 is connected with the reductor 4 that is fixed on the frame 8, and reductor 4 is connected with the winch 6 that is fixed on the frame 8;
Described torque motor 1 is connected with frame 8 through bolt;
Be covered with the bell-jar 2 that is fixed on the frame 8 on the junction of described torque motor 1 and wet friction sheet drg 3;
Described reductor 4 is rigidly connected through bolt and winch 6;
Described wet friction sheet drg 3 becomes one with reductor 4, and through being bolted on the frame 8;
Described winch 6 is provided with cylinder 5, is wound with the steel rope 7 that twines according to layer rule on the cylinder 5, and steel wire 7 is connected with the sliding machine of tensioning load-transfer device, and sliding machine is with the load-transfer device tensioning;
Described cylinder 5 is provided with coder, and coder is connected with the PLC controller.Coder is given the PLC controller with the signal feedback that collects, and the PLC controller is regulated the frequency converter output parameter according to feedack again, again by Frequency Converter Control torque motor output parameter.
Electric energy flows to torque motor by frequency converter, the outside output torque of torque motor, and torque motor passes torque to winch through reductor, drives the winch cylinder and rotates, and the steel rope on the cylinder is outwards exported tensile force, the dynamic tension long belt conveyor.Because the long belt conveyor fed distance is long more; The tensile force that needs is big more; This device can be according to the correlation parameter in the variation change PLC director demon of fed distance, so that control frequency converter output parameter finally makes the required tensile force of winch output; And in the storage distance of 600m; The acting force arm of the steel rope tensile force on the cylinder of winch diminishes along with the elongation of steel rope; Suppose that the variation range of (600m) tensile force is little in the memory range, the moment that then acts on this moment on the cylinder of winch is more and more littler; This device can be regulated the motor output parameter according to the variation of the steel rope number of plies on the winch cylinder.Coder through being arranged on the cylinder flows to the PLC controller with number of plies variable signal through handling, and then regulates the motor output torque, realizes dynamically control thus.
The utility model is not provided with extra configuration pumping plant, and is simple in structure and compact, overcome some security hidden troubles of present technology, and do not adopt the novel telescopic belt conveyer kinetic control system of tension detecting device.This patent is used for the load-transfer device of dynamic tension long belt conveyor, and for anxious stop etc. of belt feeder the safety guard-safeguard effect is arranged.
