Detailed description of the invention
Embodiment 1
See that Fig. 1 to Fig. 3, the present embodiment have main rope pulley group 1, secondary rope pulley group 2 and framework 3.Framework 3 can be a general frame, and the present embodiment uses two frameworks, two frameworks to support main rope pulley group 1 and secondary rope pulley group 2 respectively.Main rope pulley group 1 has main rope movable pulley 1-1 and two main rope fixed pulley 1-2, and the main rope of pull rope 7 passes through between the main rope fixed pulley 1-2 of main rope movable pulley 1-1 and two, and main rope movable pulley 1-1 has link (not shown).Secondary rope pulley group 2 has secondary rope movable pulley 2-1 and two secondary rope fixed pulley 2-2, and pull rope pair rope 8 passes through between pair rope movable pulley 2-1 and two secondary rope fixed pulley 2-2, and secondary rope movable pulley 2-1 has link 2-5.The top of framework 3 is provided with main rope reverse wheel 1-3, secondary rope reverse wheel 2-3, the bottom of framework 3 and be in and be respectively provided on two sides with main rope hydraulic cylinder 4 and secondary rope hydraulic cylinder 5.It is fixed with main regulation pulley 1-4 on the piston rod of main rope hydraulic cylinder 4, the piston rod of secondary rope hydraulic cylinder 5 is fixed with secondary adjustable pulley 2-4.Major and minor regulation rope 1-6,2-6 it is respectively equipped with between main regulation pulley 1-4 and main rope movable pulley 1-1, between secondary adjustable pulley 2-4 and secondary rope movable pulley 2-1.The main regulation rope 1-6 one end being arranged between main regulation pulley 1-4 and main rope movable pulley 1-1 is connected on the main support 1-7 of frame roof, main regulation rope 1-6 passes through the chute of main regulation pulley 1-4, the chute of main rope reverse wheel 1-3, and its other end is fixed on the link of main rope movable pulley 1-1.The secondary regulation rope 2-6 one end being arranged between secondary adjustable pulley 2-4 and secondary rope movable pulley 2-1 is connected on the assistant support 2-7 of frame roof, secondary regulation rope 2-6 is fixed on the link 2-5 of secondary rope movable pulley 2-1 by the chute of secondary adjustable pulley 2-4, the chute 2-3 of secondary rope reverse wheel, its other end.The length of major and minor regulation rope is all fixing, when pair rope hydraulic cylinder moves downward, secondary rope movable pulley will move upward, thus tensioning pull rope pair rope.When needing also exist for pine pull rope pair rope, secondary rope hydraulic cylinder i.e. moves upward.The tensioning of the main rope of pull rope and the operating principle unclamped are identical with pull rope pair rope.
Major and minor rope hydraulic cylinder is controlled by controlling assembly 6, and the corresponding oilhole between major and minor rope hydraulic cylinder is connected by going here and there liquid pipe 9.
Described control assembly 6 includes accumulator 6-1, oil pump 6-2, fuel tank 6-3, oil pump 6-2 passes through check valve 6-4 to accumulator 6-1 fuel feeding, accumulator 6-1 communicates with the fuel feed hole of main rope hydraulic cylinder 4, secondary rope hydraulic cylinder 5, accumulator 6-1 is connected on the pipeline of fuel tank 6-3 connect overflow valve 6-5, the P mouth of overflow valve 6-5 connects the T mouth of pressure controller 6-6, overflow valve 6-5 and connects with fuel tank 6-3.Being provided with quick return line between accumulator 6-1 and fuel tank 6-3, connecting in quick return line has stop valve 6-7.
If pull rope main rope 7 traction drive in system operation, at this moment the main rope of pull rope 7 is in tight rope state, pull rope pair rope 8 is in slack rope state, in order to make the main rope of pull rope 7 can produce driving frictional force, pull rope pair rope 8 must be tightened up, now secondary rope hydraulic cylinder 5 shrinks, and increases the tension force to pull rope pair rope 8, and Tensity size controls by controlling the valve of assembly.When the pressure of hydraulic system is less than when setting tensioning force value, and secondary rope hydraulic cylinder 5 shrinks, and tensile force increases；When the pressure of hydraulic system is more than when setting tensioning force value, and secondary rope hydraulic cylinder 5 stretches out, and tensile force is decreased to setting value.Equally, if when wire saws secondary in system operation drives, and the most main rope hydraulic cylinder 4 shrinks, and increases the tension force of rope 7 main to pull rope, when the pressure of hydraulic system is less than when setting tensioning force value, and main rope hydraulic cylinder 4 shrinks, and tensile force increases；When the pressure of hydraulic system is more than when setting tensioning force value, and main rope hydraulic cylinder 4 stretches out, and tensile force is decreased to setting value.
For ensureing that the main rope of pull rope 7 and pull rope pair are restricted being switched fast of 8 tensionings, main rope hydraulic cylinder 4 and secondary rope hydraulic cylinder 5 gang up connection by two string liquid pipes 9, thus ensure between interconnective two hydraulic cylinders quick string liquid and adapt to being switched fast and tensioning to pull rope between major-minor rope with the shortest response time, whole process is carried out fluid infusion by accumulator 6-1.When system pressure is less than the setting low pressure of pressure controller 6-6, oil pump 6-2 starts, to accumulator 6-1 and by connecting tube to major and minor rope hydraulic cylinder topping up, if system pressure value reaches the upper limit set value of pressure controller 6-6, oil pump is shut down.The maximum tension power of whole system is set by overflow valve 6-5, and hydraulic system can manually be unloaded by stop valve 6-7, and check valve 6-4 is to set to prevent tensioner hypertonia from damaging the motor of oil pump.
