Description
Technical field
The technical field of steel wire tensioning in being equipped the present invention relates to big machinery in Steel rope drive system, such as from
Distributing arm support steel wire rope telescoping mechanism in line distributing belt conveyer, more particularly to a kind of adjustable digital display type of hydraulic continuous
Tensioning apparatus and tensioning method.
Background technology
The distributing arm support telescoping mechanism of self-propelled vehicle distributing belt conveyer is mainly by hydraulic motor（Band deceleration device）、
Driving drum, passive roller, movable pulley, fixed pulley, steel wire rope and steel wire rope stretching device etc., complete the flexible expansion to arm support
Job area.The size of the initial pretightning force of steel wire rope has large effect to the service behaviour of whole distributing belt conveyer,
It is larger to additional load caused by material distributing machine if initial pretightning force is excessive, increase distributing arm support size, structure bulky, so as to
Cause to require higher to distributing belt conveyer chassis.If pretightning force is too small, steel wire rope easily occurs when bypassing pulley reel
Slip and jitter phenomenon, service life of steel wire rope and transmission efficiency are reduced, influences overall work stability.When in addition with using
Between and working environment change, the pretightning force that steel wire rope needs is also continually changing, and steel wire rope easily extends, so as to actual

Tight stroke is limited by its hydraulic cylinder its travel, can also be used for the steel wire tensioning of small size, if applied to big
The steel wire tensioning of distributing arm support in the tensioning of the steel wire rope of size, such as vehicular distributing belt conveyer, its hydraulic cylinder
Stroke with regard to not enough, in general thinking is to change the hydraulic cylinder of bigger stroke, but the hydraulic cylinder of big stroke necessarily brings peace
Fill that size is big, and weight is big, install that the increased impost of machine tool is big to it, influence the self structure intensity and stably of its machine tool
Property, and not necessarily possess the space of installation on some machine tools, it is full of contradictions, and the hydraulic pressure system that large-sized hydraulic cylinder needs

Close observation slide positioning hole second and the positioning hole first on guide plate of locating piece to it is corresponding when insert Assembly of pin, by slip positioning
Block is fixed together with guide plate；
5. removes the Assembly of pin connected between hydraulic cylinder and guide plate, start the cylinder body that hydraulic control system stretchs out hydraulic cylinder,
Now the piston rod of hydraulic cylinder is fixed on by Assembly of pin and slided on locating piece, and the cylinder body of hydraulic cylinder stretches backward, extends one
The flexible stroke of individual hydraulic cylinder；
6. inserts Assembly of pin, hydraulic cylinder is fixedly connected with guide plate, remove and slide what is connected between locating piece and guide plate
Assembly of pin；
7. repeat steps 4. -6., while the numerical value that the digital display device for observing sensor is shown, until steel wire rope reaches default
Force value；
If 8. by step 4.-be 7. not reaching to pre-set tension value, but reach fine setting scope, then by adjusting adjustable double end
Bolt connecting device is finely adjusted, and makes the display numerical value of pulling force sensor consistent with default tension values；
Remove the Assembly of pin slided between locating piece and guide plate, by pulling force sensor and hydraulic control control system with
The connection of on-line automatic control module, the on-line automatic action for controlling hydraulic cylinder is come according to the numerical value of pulling force sensor so as to ensure steel
The tension force of cord.
