Technical Field

[0001] The invention relates to the technical field of pipeline installation, in particular to a pipeline installation device. Background Art

[0002] Large-diameter socket-and-spigot pipes are generally very heavy and bulky, and their movement and installation require mechanical assistance, making them difficult to move using only manpower.

[0003] There are three main methods for installing existing spigot-and-socket pipes. The first is to use an excavator to directly push the pipe spigot into the socket. The traditional method of using an excavator to install pipes is suitable for medium and large diameter pipes. The installation quality cannot be guaranteed and the pipe structure will be damaged. The second is to use a hand chain hoist for installation. The existing hand chain hoist pipe installation method can easily cause the pipe to be eccentrically stressed, and the pipe structure and anti-corrosion layer may be easily damaged. The rubber ring may be misaligned and fall off, and the pipe sealing may be affected. The third is to use a crowbar to install the pipe. The existing crowbar installation method is only suitable for small diameter pipes, which have a small mass and volume.

[0004] When installing large-diameter pipelines, traditional construction equipment takes up a lot of space, and the cumbersome construction steps make the construction time-consuming and laborious. In addition, the pipeline cannot be well protected during the construction process, which may cause damage to the pipeline itself or misalignment and falling of the rubber ring, affecting the sealing of the pipeline.

Then the limiting cylinder is driven downward by the grip rod so that the first clamping block is separated from the second clamping block, and the guide block slides in the first guide groove until the guide block enters the second guide groove from the first guide groove. Then the limiting cylinder is rotated so that the guide block slides from the second guide groove into the third guide groove. The grip rod is released, so that the guide block and the third guide groove cooperate to limit the limiting cylinder, and the first rotation limiting block is separated from the second rotation limiting block to cancel the rotation limit of the winding drum, so that the length of the wire rope can be adjusted by the winding knob to adapt to the installation of pipes of different lengths.

[0027] The limit cylinder is driven to move by the grip rod, so that the guide block enters the first guide groove through the third guide groove and the second guide groove. At this time, the grip rod is released, and the holding spring holds the limit cylinder to move outward, so that the first clamping block is engaged with the second clamping block, and the first rotation limit block is engaged with the second rotation limit block. The first rotation limit block and the second rotation limit block cooperate to limit the rotation of the winding drum, thereby preventing the length of the wire rope from changing when the jack is working, and the first clamping block and the second clamping block cooperate to transfer the rotation pressure of the limit cylinder part to the movable ring, thereby ensuring the limitation of the winding drum by the limit cylinder, and improving the service life of the limit cylinder and the winding drum, and the handle drives the connecting rod to move, so that the limiting ring is sleeved on the end of the grip rod, further limiting the limit cylinder, and the connecting rod is limited by multiple limit blocks, thereby dispersing the pressure on the limit cylinder again, ensuring the limitation of the winding drum by the limit cylinder, and improving the service life of the limit cylinder and the winding drum.

Until the guide block 15 enters the second guide groove 1602 from the first guide groove 1601, and then rotate the limit cylinder 14 so that the guide block 15 slides from the second guide groove 1602 into the third guide groove 1603, release the grip 20, and the guide block 15 and the third guide groove 1603 cooperate to limit the limit cylinder 14, and the first rotation limit block 30 and the second rotation limit block 31 are disengaged to cancel the rotation limit on the winding drum 17, so that the length of the wire rope 2 can be adjusted by the winding knob 12 to adapt to the installation of pipes of different lengths.

[0060] The specific solution is as follows: by placing the adjusting shell 4 in front of the pipe to be installed, adjusting the height of the adjusting shell 4 through the lifting platform 7, so that the jack 3 is just aligned with the pipe wall of the pipe, and then the socket of the previous pipe is covered with the wire rope 2, and the jack 3 is started. Then, the socket of the pipe to be installed is slowly inserted into the socket of the previous pipe under the action of the jack 3 until it is inserted to the specified depth.

[0061] Through the cooperation of the wire rope 2 and the jack 3, the installation and construction process is greatly simplified, saving time and labor, and the pipeline is installed simply and efficiently. The quality of the interface installation is guaranteed, and no damage is caused to the pipe itself. In addition, the jack 3 exerts force to push the pipeline forward, and the pushing depth of the jack 3 can be adjusted according to the actual situation during the pushing process, thereby ensuring that the rubber ring at the pipeline connection will not fall off or be misplaced during the pushing process, thereby ensuring the sealing of the pipeline connection.

At this time, the connecting rod 22 is in a vertical state and is limited by the two limiting blocks 24. Then, the limiting cylinder 14 is driven downward by the grip 20, so that the first block 18 is separated from the second block 19, and the guide block 15 is in the first guide groove 1 601 until the guide block 15 enters the second guide groove 1602 from the first guide groove 1601, and then the limit cylinder 14 is rotated to make the guide block 15 slide from the second guide groove 1602 into the third guide groove 1603, and the grip 20 is released, so that the guide block 15 cooperates with the third guide groove 1603 to limit the limit cylinder 14, and the first rotation limit block 30 and the second rotation limit block 31 are disengaged to cancel the rotation limit on the winding drum 17, so that the length of the wire rope 2 can be adjusted by the winding knob 12 to adapt to the installation of pipes of different lengths.

[0064] After the adjustment is completed, the limit cylinder 14 is driven to move by the grip 20, so that the guide block 15 enters the first guide groove 1601 through the third guide groove 1603 and the second guide groove 1602. At this time, the grip 20 is released, and the holding spring 33 holds the limit cylinder 14 to move outward, so that the first clamping block 18 is engaged with the second clamping block 19, and the first rotation limit block 30 is engaged with the second rotation limit block 31. The first rotation limit block 30 and the second rotation limit block 31 cooperate to limit the rotation of the winding drum 17, thereby preventing the length of the wire rope 2 from changing when the jack 3 is working, and the first clamping block 1 8 cooperates with the second clamping block 19 to transfer the rotational pressure of the limit cylinder 14 to the movable ring 5, ensuring that the limit cylinder 14 limits the winding drum 17 and improves the service life of the limit cylinder 14 and the winding drum 17, and drives the connecting rod 22 to move through the handle 23, so that the limit ring 21 is sleeved on the end of the grip rod 20, further limiting the limit cylinder 14, and limiting the connecting rod 22 through multiple limit blocks 24, so as to disperse the pressure on the limit cylinder 14 again, ensuring the limit cylinder 14 limits the winding drum 17 and improving the service life of the limit cylinder 14 and the winding drum 17.
