The operation principle of the utility model：
During SQ-1200 endless rope series tractor no-load running, the pressure of HYDRAULIC CONTROL SYSTEM is arranged to maximum tension force value, if main
Restrict 6 load runnings, during in tension, pair rope 61 then be in relaxed state, between guarantee driving wheel 7 and haulage cable
With enough frictional force, that is, tractive force, secondary rope 61 must be tensioned, under the control of hydraulic system, has bar to secondary rope hydraulic cylinder 40
Chamber hydraulic fluid port fuel feeding, the piston rod of pair rope hydraulic cylinder 40 are inwardly indented under the action of oil pressure in secondary rope hydraulic cylinder 40, drag secondary rope
Mobile stent 201 is moved rearwards, 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 there is enough frictional force, that is, tractive force, palpus between driving wheel 7 and haulage cable
Main rope 6 is tensioned, 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 under the action of oil pressure in main rope hydraulic cylinder 4, is dragged the main mobile stent 21 of rope and is moved rearwards, 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 fulfill pressure oil in main rope hydraulic cylinder 4
Restrict pair and carry out quick liquid leakage between hydraulic cylinder 40, and the quick of main rope 6 and secondary rope 61 can be adapted to the shortest reaction time
Switching, is tensioned traction rope.Tensile force size is to control realization, 10 output pressure of oil pump by hydraulic control system
Oil, enters throttle valve 15, after throttle valve 15 and hydraulic control one-way valve 16 after overflow valve 11 adjusts pressure by solenoid valve 12
To accumulator 18 and main rope hydraulic cylinder 4 or secondary rope 40 rod chamber fuel feeding of hydraulic cylinder, 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.Pressure transmitter 17 at 18 oil inlet of accumulator is right
Oil pressure is detected.When pressure at pressure transmitter 17 is less than setting value, the motor and solenoid valve 12 of control oil pump 10 are logical
Electricity, supplements hydraulic oil, the piston rod retraction of the piston rod of main rope hydraulic cylinder 4 or secondary rope hydraulic cylinder 40, works as pressure to accumulator 18
When the pressure of transmitter 17 exceedes setup pressure value, the power-off of the motor of solenoid valve 12 and oil pump 10 is controlled, is stopped to accumulator 18
And main rope hydraulic cylinder 4 or secondary rope hydraulic cylinder 40 supplement hydraulic oil, so as to keep the constant pressure in hydraulic cylinder and then realize main rope 6
With the constant-tension of secondary rope 61.
