The working principle is as follows: when the protective belt needs to be wound on a petroleum pipeline, a worker firstly screws the locking nut 402 from the rotary screw 401, places the coiled protective belt on the rotary screw 401, and then screws the locking nut 402 back to the rotary screw 401 to limit the coiled protective belt; the worker then places the petroleum pipe into the mounting plate 306 and allows the left end of the petroleum pipe to contact the two drive wheels 505, and then the worker wraps one end of the protective tape around the petroleum pipe. Since the position of the locking nut 402 on the rotary screw 401 is adjustable, it is possible to place guard bands of different widths on the rotary screw 401.
The worker also needs to rotate the lifting screw 607 to make the two guide blocks 601 drive the connecting frame 602 and the two supporting rollers 603 to move upwards, and when the two supporting rollers 603 move upwards to support the petroleum pipeline, the worker can stop rotating the lifting screw 607. Because the height of the two supporting rollers 603 is adjustable, the two supporting rollers 603 can support petroleum pipelines with different sizes.
After all preparation work is done, a worker starts the driving motor 302, the driving motor 302 can drive one of the transmission gears 304 and one of the bevel gears 501 to rotate through one of the power shafts 303, one of the transmission gears 304 can drive the hollow gear 311, the other transmission gear 304, the other power shaft 303 and the other bevel gear 501 to rotate, the hollow gear 311 can drive the mounting plate 306 and the annular slide block 305 to rotate, the mounting plate 306 can drive the two sliding sleeves 307 and the sliding rod 308 to rotate, the sliding rod 308 can drive the whole unreeling mechanism 4 to rotate along the periphery of the petroleum pipeline, and at the moment, the protective belt can be continuously wound on the petroleum pipeline. Because the two clamping rods 404 can play a role in increasing frictional resistance on the rotary screw 401, the rotary screw 401 can be prevented from rotating too fast in the winding process of the protective belt, and the protective belt can be tensioned all the time in the winding process, so that the protective belt is favorably and tightly wound on a petroleum pipeline. The first two bevel gears 501 drive the two rotating shafts 503 and the two driving wheels 505 to rotate through the second two bevel gears 504, and at the moment, the two driving wheels 505 drive the petroleum pipeline to move leftwards, so that the outer wall of the whole petroleum pipeline is wound with the protective belt.
One of the support rollers 603 moves upward to drive the two bevel gears three 604 to move upward, and because the bevel gears four 605 are arranged on the spline shaft 608, and the spline shaft 608 is slidably arranged on the rotating shaft 503, the two bevel gears three 604 move upward against the two bevel gears four 605, so that the two bevel gears three 604 can be always meshed with the two bevel gears four 605. The two rotating shafts 503 can drive the two bevel gears four 605 to rotate through the two spline shafts 608, the two bevel gears four 605 can drive one of the supporting rollers 603 to rotate through the two bevel gears three 604, and at the moment, the two supporting rollers 603 can also transmit the pipelines, so that the winding requirements of the protective belts of petroleum pipelines with different sizes can be met.
When protective belt winding operation needs to be performed on petroleum pipelines with small diameters, workers can rotate the adjusting screw 310 to enable the fixing nut 309 to drive the sliding rod 308 to move downwards, the sliding rod 308 can drive the whole unreeling mechanism 4 to move downwards, the rotary screw 401 can drive the protective belt winding drum to move downwards to be close to the petroleum pipelines, and therefore the situation that the protective belt is too long in length when being pulled out in the winding process can be avoided, and the protective belt can also be tightly wound on the petroleum pipelines with small diameters. After the wrapping operation of the petroleum pipeline protective tape is completed, the worker turns off the driving motor 302.
