Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of machine room pipeline jacking, and particularly relates to a large U-shaped lightweight fabricated machine room pipeline jacking structure. BACKGROUND

[0002] The large U-shaped lightweight fabricated machine room is widely used in various heavy steel structure buildings due to high space utilization rate and controllable construction period. The mechanical and electrical pipelines (especially steel pipe pipelines) in the machine room need to be installed at a height of more than 13 m, and the single steel pipe is heavy in weight, and the pipeline length is usually long, so the stability and accuracy of the installation process are required.

[0003] At present, the industry generally uses a curved arm elevator to cooperate with a traditional clamping device to complete the jacking and butt joint installation of the steel pipe, but there are significant defects. On the one hand, the traditional clamping device lacks center positioning adjustment function. Because the steel pipe itself is heavy in weight, the left and right centers are unbalanced due to uneven force distribution during clamping, the steel pipe shakes violently during jacking, which not only increases the safety risk of high-altitude operation, but also may cause damage to the pipeline surface due to imbalance. On the other hand, in the butt joint link of the steel pipe end and the installed pipeline, the positioning accuracy of the clamping device is insufficient and the weight of the steel pipe is affected, and the butt joint is easily skewed. The weight characteristics of the steel pipe make it difficult for the operator to conveniently adjust its position in the air, and it is necessary to repeatedly move the elevator or use additional auxiliary tools for correction, which not only seriously affects the construction efficiency, but also may cause the sealing performance of the butt joint to decrease due to repeated adjustment, leaving hidden dangers in later use.

[0021] The specific working process is as follows: the large U-shaped steel pipe to be jacked up is placed on the two arc-shaped support frames 9 at the top end of the support table 4, the extruded rubber pads in the support frames 9 can buffer the hard contact between the pipe and the support table 4, avoid the surface wear of the pipe and increase the friction.

[0022] In this process, in each group of arc-shaped locking blocks 7, the positioning block 7-2 of one locking block is inserted into the positioning hole 7-1 of another locking block to ensure accurate docking; after the inner arc wall of the arc-shaped locking block 7 is attached to the outer wall of the steel pipe, the locking screw on the locking plate is inserted through the corresponding locking hole and tightened to achieve rigid clamping of the two sides of the steel pipe; the rolling balls 7-3 on the inner arc wall of the arc-shaped locking block 7 reduce friction with the steel pipe during clamping, avoid scratching the surface of the pipe, and provide a certain sliding allowance for subsequent angle adjustment.

[0023] After the pipe is fixed, two pressure sensors 8-2 respectively detect the pressure values on both sides of the steel pipe in real time and transmit the data to the control system.

[0024] When there is a difference in pressure on both sides, the control system triggers the electric telescopic rods 2-1 on both sides of the guide rail 2 to start: the electric telescopic rods 2-1 push the U-shaped pipe 2-2 to move horizontally, and the U-shaped pipe 2-2 drives the adjusting rod 6 to move synchronously; since the adjusting rod 6 is connected to the arc-shaped locking block 7 through the sliding sleeve 6-1 and the sliding rod 6-5, and the arc-shaped locking block 7 is suspended with the counterweight block 7-5 through the hanger 7-4, the displacement of the adjusting rod 6 changes the distance between the counterweight block 7-5 and the center of gravity of the steel pipe, dynamically adjusts the stress of the counterweight on both sides of the steel pipe by using the principle of leverage, and moves the counterweight block 7-5 on the side with smaller pressure away from the steel pipe until the pressure values detected by the two pressure sensors 8-2 tend to be consistent, achieving stress balance before the steel pipe is jacked up.

[0025] Meanwhile, after installation is completed, the bearing cylinder 7-8 on the connecting frame 7-6 and the supporting rod 7-7 on the side wall of the mounting frame 1 slide together to bear part of the weight of the counterweight block 7-5, avoiding additional stress on the steel pipe due to the gravity of the counterweight block 7-5 during the initial fixing stage, and further ensuring the accuracy of balance adjustment.

[0026] When the steel pipe is jacked up to the docking height with the already installed pipe on the side, the hoisting part on the steel beam is preliminarily matched with the steel pipe without being locked to facilitate the fine adjustment of the end docking angle. At this time, the locking pin 8-3 on the rotating adjusting cylinder 8 is rotated, and the pressure sensor 8-2 is lowered and separated from the bottom of the steel pipe by the top rod 8-1, avoiding the participation of the pressure sensor 8-2 in the subsequent angle adjustment and eliminating its interference with the posture of the steel pipe.

[0027] The operator holds the remote controller to control the three-phase asynchronous motor 2-4 to start: the three-phase asynchronous motor 2-4 drives the gear column 2-5 to rotate through the connecting shaft, the gear column 2-5 is engaged with the driving gear 2-7 to transmit power, the first lead screw 2-6 rotates and moves axially along the fixed plate 2-3, and then pushes the adjusting rod 6 to make a slight displacement. The fine adjustment of the adjusting rod 6 is transmitted to the arc-shaped locking block 7 through the sliding sleeve 6-1 and the sliding rod 6-5, and the lever action of the counterweight block 7-5 makes the end of the steel pipe rise or sink slightly to achieve accurate alignment with the end of the pipe on the side.

[0028] After alignment, the welding work is completed, and then the lifting member on the steel beam is locked and fixed with the steel pipe to complete the pipeline installation.

[0029] The preferred embodiments of the present application are shown and described above, the present application is not limited by the above-mentioned embodiments, the above-mentioned embodiments are only to illustrate the principles of the present application, various changes and improvements without departing from the spirit and scope of the present application fall within the scope of the claimed present application.
