During SQ-1200 endless rope series tractor no-load running, the pressure of HYDRAULIC CONTROL SYSTEM is set to maximum tension force value, if main
Restrict 6 load runnings, during in tension, pair rope 61 is then in relaxed state, to ensure between driving wheel 7 and haulage cable
It is tractive force with enough frictional force, secondary rope 61 must be tensioned, under the control of hydraulic system, has bar to secondary hydraulic cylinder 40 of restricting
Chamber hydraulic fluid port fuel feeding, the piston rod of pair rope hydraulic cylinder 40 is inwardly indented in the presence of oil pressure in secondary rope hydraulic cylinder 40, the secondary rope of dragging
Mobile support 201 is moved rearwards by, so that pair rope 61 be tensioned；When the pressure of hydraulic system is more than setting Zhang Jinzhan power, pair rope
The piston rod of hydraulic cylinder 40 stretches out, and tensile force is decreased to setting value.Similarly, if 61 load runnings of secondary rope, during in tension,
Main rope 6 is then in relaxed state, to ensure between driving wheel 7 and haulage cable to there is enough frictional force to be tractive force, palpus
The main rope 6 of tensioning, under the control of hydraulic system, to the rod chamber hydraulic fluid port fuel feeding of main rope hydraulic cylinder 4, the piston of main rope hydraulic cylinder 4
Bar is inwardly indented in the presence of oil pressure in main rope hydraulic cylinder 4, is dragged the main mobile support 21 of rope and is moved rearwards by, so that by main rope 6
Tensioning；When the pressure of hydraulic control system is more than setting Zhang Jinzhan power, the piston rod of main rope hydraulic cylinder 4 stretches out, and tensile force subtracts
As low as setting value.
The main rope hydraulic cylinder 4 of hydraulic control system control and secondary rope hydraulic cylinder 40, so as to realize pressure oil in main rope hydraulic cylinder 4
Quick liquid leakage is carried out between pair rope hydraulic cylinder 40, and can be with the quick of the most short main rope 6 of reaction time adaptation and secondary rope 61
Switching, is tensioned to pull rope.Tensile force size is to be controlled to realize by hydraulic control system, the output pressure of oil pump 10
Oil, enters choke valve 15, after choke valve 15 and hydraulic control one-way valve 16 after adjusting pressure through overflow valve 11 by magnetic valve 12
To accumulator 18 and main rope hydraulic cylinder 4 or the secondary rope rod chamber fuel feeding of hydraulic cylinder 40, the piston rod of main rope hydraulic cylinder 4 or secondary rope hydraulic pressure
The piston rod back shrinkage of cylinder 40 realizes the tensioning of main rope 6 or secondary rope 61.17 pairs of pressure transmitter at the oil inlet of accumulator 18
Oil pressure is detected.When pressure at pressure transmitter 17 is less than setting value, the motor and magnetic valve 12 of control oil pump 10 lead to
Electricity, hydraulic oil is supplemented to accumulator 18, and pressure is worked as in the piston rod retraction of the piston rod of main rope hydraulic cylinder 4 or secondary rope hydraulic cylinder 40
When the pressure of transmitter 17 exceedes setup pressure value, the motor power-off of control magnetic valve 12 and oil pump 10 stops to accumulator 18
