The following describes a one-time use procedure of the present invention with reference to the accompanying drawings:
the connection and adjustment of the wire rope in the off-machine state of the wire rope retractor will be described as an example.
Firstly, the base plate 1 is fixedly mounted on a bench work table through screws, then the mounting seat 2 is fixedly mounted on the base plate 1 through screws, then the steel rope tractor is placed in a groove of the mounting seat 2, the lug seat on the shell of the steel rope tractor is aligned with a screw hole above the mounting seat 2, and finally the lug seat is connected to the mounting seat 2 through screws, so that the fixing of the steel rope tractor is realized.
After the steel rope tractor is fixed, the lower fixing seat 3 and the upper fixing seat 4 are combined together and sleeved on the shell of the steel rope tractor, and then the lower fixing seat 3 and the upper fixing seat 4 are fixedly connected together by the screw, so that other parts on the upper fixing seat 4 are also installed in place at the same time.
After the preparation work is finished, the wrench 9 is inserted onto the twelve-angle spline shaft of the mandrel 7 through the twelve-angle spline hole, the wrench 9 is mounted, and the wrench 9 is detachably mounted so as to avoid mounting collision and interference. When the wrench 9 is installed, the wrench 9 can be rotated, the mandrel 7 can be driven to synchronously rotate through the wrench 9, the rotating mandrel 7 drives the swinging rod 10, the dowel bar 11 and the shifting block 12 to synchronously move, finally, the shifting block 12 generates shifting thrust to the rocker arm of the steel rope tractor, the rocker arm rotates around the swinging center line of the rocker arm by a corresponding angle, after the rocker arm swings in place, the positioning pin 8 is pushed inwards, the inner end of the positioning pin 8 is inserted into the positioning hole 13 at the corresponding position on the positioning disc 6, and finally, the positioning pin pressing screw 15 is screwed, so that the positioning pin 8 is prevented from moving again. The cable connection and adjustment work can then be performed on the cable retractor, and since the rocker arm of the cable retractor is now fully jammed by the dial block 12, the rocker arm is not likely to be suddenly reset at the reset resistance of the wrap spring, in which state the connection and the associated adjustment work of the cable can be performed safely by the staff.
After the wire rope connection and debugging work of the wire rope tractor is finished, the wrench 9 is held again, the positioning pin pressing screw 15 is loosened, the inner end of the positioning pin 8 is pulled out of the positioning hole 13 on the positioning disc 6, the wrench 9 is slowly released until the rocker arm gradually swings back to the initial position under the action of the restoring force of the coil spring, the wrench 9 is firstly detached, and finally the screw between the fixing seat 3 and the upper fixing seat 4 is loosened, so that the whole wire rope tractor is detached from the shell of the wire rope tractor, and all operations are finished.
Similarly, when the cable retractor is connected and debugged in the on-machine state, the base plate 1 and the mounting seat 2 are not needed, the cable retractor is directly fixed at the corresponding position of the aeroengine, and the lug seat on the shell of the cable retractor is connected to the aeroengine by using the screw, so that the fixation of the cable retractor is realized. When the cable retractor is fixed, the operation can be performed with reference to the cable connection and debugging process of the cable retractor in the off-machine state.
The embodiments are not intended to limit the scope of the invention, but rather are intended to cover all equivalent implementations or modifications that can be made without departing from the scope of the invention.
