The specific embodiment
Dynamometry oil cylinder (11) is by common single action piston cylinder repacking, and the rodless cavity oil inlet is stopped up, and aie escape valve is housed above rodless cavity, and the aie escape valve of a band pressure gauge joint then is housed above rod chamber.
Shutoff valve (5) is connected with the rod chamber oil inlet of dynamometry oil cylinder (11) through pressure sensor (6), and compression indicator (13) is connected on the relief port of dynamometry cylinder rod chamber.In the permanent tension force operational process of adhesive tape tensioning and conveyer, tension monitor provides in real time, conveyor belt tension value accurately, and feeds back to electrical controller, comes modulated pressure device and hydraulic wireline winch to realize accurate adjusting to the adhesive tape tensile force by control program.
The oil outlet of Hydraulic Pump (2) through by pass valve (3), check valve (4) respectively with tension monitor, the rod chamber of hydraulic wireline winch locking cylinder (7) and hydraulic wireline winch drive this three part of loop and link to each other.Drive on the loop at hydraulic wireline winch, connecting solenoid directional control valve (27) and hand change over valve (26), A mouth serial connection hydraulic control one-way valve (25), electromagnetic proportion relief valve (24) and the check valve (23) and the flow regulating valve (22) in parallel of hand change over valve (26), the A mouth with hydraulic wireline winch motor (21) is connected again.The B mouth of hand change over valve (26) is linked on the B mouth of hydraulic wireline winch motor (21) by one-way throttle valve (20).
The present invention can select automatically and manual two kinds of mode of operation.
Automatic mode of operation:, set the size of adhesive tape starting tensile force, normal tensile force by initial parameter according to the requirement of conveyer tensile force.Wait for the conveyer main signal, receive the signal that allows starting after, under the control of control program, finish starting section, normal target phase to the control of the permanent tension force of adhesive tape and by the starting tensile force to the flexible control that changes of normal operation tensile force.After its detailed process is the pump starting, the solenoid directional control valve commutation, the pressure of control output signal control electromagnetic proportional valve able to programme, make adhesive tape reach the starting tensile force, after the starting of time-delay conveyer such as a period of time, the tension force the when pressure of Controlled by Programmable Controller electromagnetic proportional valve makes adhesive tape reach conveyer normally to move.When reaching the normal operating condition of adhesive tape, hydraulic wireline winch is implemented braking, to keep the tension force of adhesive tape.Hydraulic Station quits work subsequently, and whole hydraulic efficiency gear is in passive state.After this when measuring tensile force, the tension force control monitor unit descends, then reset hydraulic efficiency gear, drive hydraulic wireline winch tensioning adhesive tape and do not exceed the error allowed band, and enter the tension force monitor state until tensile force, send adhesive tape signal out of service up to conveyer, whole device quits work.
Manual work mode: when electrical controller of the present invention breaks down or in order to safeguard, overhaul the belt conveyer complete machine, in the time of can being transformed into manual state to the mode of operation knob, control adhesive tape tensioning or lax artificially, and regulate the adhesive tape tensile force according to the display data of tension force control monitor unit.
