The present utility model is described in further detail below with reference to examples.

The device relies on a project of south-to-north water transfer matched engineering east line, and has high pipeline specification and great self-weight. The pipe joint cannot be manually selected to adjust the installation angle of the punching hole in the pipe installation process, the pipe is easily damaged through the adjustment of the excavator, and meanwhile, the potential safety hazard is large.

The utility model provides a concrete embodiment of an auxiliary rotating device for a PCCP pipeline on a construction site, which comprises the following steps:

referring to fig. 1-5, the PCCP pipeline auxiliary rotating device for a construction site comprises a base 7, wherein two rotating rollers 1 and two indicating rods 2 are arranged on the upper side of the base 7, and in the embodiment, the base 7 is of a plate-shaped structure; in other embodiments, the base 7 may be a frame structure, so as to support the rotating roller 1 and the indication rod 2.

The two rotating rollers 1 can rotate and are supported on the lower side of the PCCP pipe 18, and the two rotating rollers 1 are arranged in parallel; the two ends of the rotating roller 1 are respectively provided with a first support 8 for supporting the rotating roller 1 to rotate, a first bolt 9 is arranged on the lower part of the first support 8 in a penetrating way, and a plurality of first threaded holes 10 matched with the first bolts 9 are formed in the upper side of the base 7; the first bolt 9 is matched with first threaded holes 10 at different positions to fix the first support 8 and the rotating roller 1 at different positions, so that the adjustment of the distance between the two rotating rollers 1 is realized; the angle of the rotating roller 1 is adjustable, so that the rotating roller can be suitable for supporting PCCP pipelines 18 with different specifications.

The upper side of the base 7 is provided with a gear motor 6, the gear motor 6 is connected with a belt transmission mechanism 5 and drives the belt transmission mechanism 5, and the belt transmission mechanism 5 is connected with the end part of one rotating roller 1. The belt transmission mechanism 5 and the gear motor 6 are driven to enable the rotation of the rotating roller 1.

The gear motor 6 downside is equipped with the second support 11 that supports gear motor 6, and second bolt 12 is worn to be equipped with in second support 11 lower part, and base 7 upside is equipped with a plurality of second screw holes 13 with second bolt 12 complex. The second bolt 12 is matched with a second threaded hole 13 at a different position, so that the position of the gear motor 6 can be adjusted to adapt to the change of the position of the rotating roller 1.

The outer diameter of the middle part of the rotating roller 1 is smaller than the outer diameters of the two ends; the outer diameter of the middle part is smaller, so that the lifting belt is convenient to be matched with the lifting belt, and the influence of the lifting belt on the rotation of the PCCP pipeline 18 is avoided.

Rubber sleeves 4 are sleeved outside the two ends of the rotating roller 1. A rubber belt is wound on the outer side of the end part of the rotating roller 1 to form a rubber sleeve 4. The rubber sleeve 4 can reduce slipping phenomenon, ensure stable rotation of the PCCP pipe 18 and avoid damage to an outer anti-corrosion layer of the PCCP pipe 18.

Both the indicating rods 2 are vertically arranged outside the end part of the PCCP pipe 18 with the pressing hole 19 and are symmetrical to two sides of a vertical surface where the center line of the PCCP pipe 18 is positioned. As shown in fig. 3, without the indication rod 2, a worker can only rotate two of the pressing holes 19 to the uppermost end and the lowermost end as much as possible, so that the efficiency is low, and with the indication rod 2, the worker can know whether the pressing holes 19 are in a reasonable position interval, thereby improving the efficiency.

The base 7 upside is equipped with two fixed blocks 14, and fixed mounting has guide bar 15 between two fixed blocks 14, and the rotation is installed lead screw 16, and guide bar 15 is parallel with lead screw 16, and all passes pilot rod 2, and lead screw 16 divide into two parts, and the two parts of lead screw 16 have the screw thread that revolves opposite direction, and pass through threaded connection with two pilot rods 2 respectively, and the center of lead screw 16 corresponds with the center of PCCP pipeline 18, and lead screw 16 one end passes fixed block 14 to be connected with hand wheel 17. The screw rod 16 is driven to rotate by rotating the hand wheel 17, and the screw rod 16 enables the two indicating rods 2 to synchronously approach or separate along the guide rod 15, so that the adjustment of the distance between the two indicating rods 2 is realized. The flexibility of the position of the indication rod 2 is improved, and the position of the punching hole 19 is conveniently controlled; and can also be applied to PCCP pipelines 18 of different specifications.

The laser 3 is installed to the indicator beam 2 towards the PCCP pipe 18 side, and in this embodiment, the laser 3 adopts the laser 3 for the level gauge in the prior art, and can project two green light rays corresponding vertically to the upper and lower inner walls of the PCCP pipe 18. The laser 3 projects light on the inner wall of the PCCP pipeline 18, so that whether the punching hole 19 is positioned in a reasonable position interval or not can be observed conveniently; without the laser 3, the worker can only observe the edge of the indicator bar 2 with his eyes, which is time-consuming and subject to deviations.

It should be noted that; the ends of the indication rod 2 and the PCCP pipe 18 with the punching holes 19 are preferably positioned on the illuminated side of the device, so that the influence of sunlight can be reduced, and the green light rays projected by the laser 3 are more obvious and better.

The using method comprises the following steps: when the punching hole 19 is not in a reasonable position interval, as shown in fig. 3, the PCCP pipe 18 is firstly hoisted to the upper side of the rotating roller 1; the gear motor 6 works to drive one rotating roller 1 to rotate through the belt transmission mechanism 5 so as to enable the PCCP pipeline 18 to rotate, and the other rotating roller 1 is assisted to rotate;

the worker can stand outside the indication rod 2 to observe the opposite side of the indication rod 2 toward the inner wall of the PCCP pipe 18 or directly observe the light projected by the laser 3. When the pressing hole 19 moves between the two indication rods 2 or between the green lights of the inner wall of the pipeline, the rotation of the PCCP pipeline 18 is completed.
