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 number of hydraulic continuous
The tensioning method of explicit tensioning apparatus.
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 working performance of entire distributing belt conveyer,
If initial pretightning force is excessive, the additional load generated to material distributing machine is larger, increases 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 is susceptible to when bypassing pulley reel
Slip and jitter phenomenon reduce service life of steel wire rope and transmission efficiency, influence overall work stability.When in addition with using
Between and working environment variation, the pretightning force that steel wire rope needs is also continually changing, and steel wire rope easily extends, so as to practical

1. is fixed in the parallel position setting of the extended line of the steel wire rope guide plate, the bottom of the guide plate in rack,
By the slip locating piece by its holding tank riding suit on guide plate top；
2. steel wire ropes, will by the rope end fixing device connection adjustable stud bolt attachment device and pulling force sensor
Pulling force sensor is connect with the slip locating piece；
3. hydraulic cylinder is installed to by Assembly of pin on the guide plate by, then the piston rod end of hydraulic cylinder is connected
Plug is attached with sliding the connector of locating piece by Assembly of pin；
4. hydraulic cylinders connect hydraulic control system by pipeline, start the piston rod that hydraulic control system shrinks hydraulic cylinder, hydraulic pressure
The piston rod of cylinder, which drives, slides locating piece, pulling force sensor, adjustable stud bolt attachment device, wire rope end fixing device
Steel wire rope is pulled to be moved to the direction that steel wire rope tenses together, when a retraction stroke of hydraulic cylinder closes to an end, matched simultaneously
Close observation slide location hole second and the location hole first on guide plate of locating piece to it is corresponding when be inserted into 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,
The piston rod of hydraulic cylinder is fixed on by Assembly of pin and slided on locating piece at this time, and the cylinder body of hydraulic cylinder stretches backward, extends one
The flexible stroke of a hydraulic cylinder；
6. is inserted into Assembly of pin, hydraulic cylinder is made to be fixedly connected with guide plate, remove and slide what is connected between locating piece and guide plate
Assembly of pin；
7. repeat step 4. -6., while the numerical value that the digital display device for observing sensor show is opened until steel wire rope reaches default
Force value；
If 8. by step 4. -7. do not reach pre-set tension value, but reach fine setting scope, then by adjusting adjustable double end
Bolt connecting device is finely adjusted, and the display numerical value for making pulling force sensor is consistent with preset tension values；
9. remove the Assembly of pin slided between locating piece and guide plate, by pulling force sensor and hydraulic control control system with
Line automatic control module connects, according to the numerical value of pulling force sensor come the action of on-line automatic control hydraulic cylinder so as to ensure steel wire
The tension of rope.
