Description

Technical Field

[0001] The utility model relates to the technical field of pipeline transportation, in particular to a pipe body transportation structure for a pipe jacking machine. Background Art

[0002] As the pace of urban construction continues to accelerate, municipal pipeline construction is becoming more and more frequent. In order to avoid excavating roads to bury pipes, pipe jacking machines are usually used for construction. Pipe jacking construction is a trenchless construction method, a pipeline burial construction technology that does not involve excavation or less excavation. Pipe jacking construction is to use the jacking force generated by the jacking equipment in the working pit to overcome the friction between the pipeline and the surrounding soil, push the pipeline into the soil according to the designed slope, and transport the soil away. After one section of the pipe is pushed into the soil layer, the second section of the pipe is lowered to continue pushing. The principle is to use the thrust of the main jacking cylinder and the pipeline room, relay room, etc. to push the tool pipe or tunneling machine from the working pit through the soil layer and lift it into the receiving pit. The pipeline follows the tool pipe or tunneling machine and is buried between the two pits;

[0003] After the pipe jacking machine pushes the pipe into place during operation, the pipe jacking machine is reset again. At the same time, the construction workers need to use a crane to lift the pipe from the ground and transport it to the working end of the pipe jacking machine. The crane is located on the ground, and the pipe jacking machine is located inside the working pit. The crane driver needs to use a walkie-talkie to communicate with the construction workers in the working pit to adjust the height of the pipe. Continuous debugging and communication are required to transport the pipe to the working end of the pipe jacking machine, which consumes a lot of time and reduces work efficiency. At the same time, when the crane lifts the pipe, the construction workers need to use strapping to fix the pipe. If the strapping is loose, the pipe may fall, which poses a certain safety risk.

[0010] Preferably, a partition is fixedly connected to the inner wall of one end of the slide rail, and a through hole is opened on the side surface of the partition.

[0011] Preferably, one end of the forward and reverse screw rod passes through the through hole on the side surface of the partition and is fixedly connected to the power output end of the second servo motor, one side of the second servo motor is fixedly connected to the inner wall of the slide rail, and the other end of the forward and reverse screw rod is rotatably connected to the inner wall of the slide rail.

[0013] Compared with the related art, the pipe conveying structure for the pipe jacking machine provided by the utility model has the following beneficial effects:

[0014] By providing a lifting structure, the rotation of the power output end of the first servo motor drives the driving gear to rotate, and the rotation of the driving gear drives the driven gear to rotate, and the rotation of the driven gear drives the two ends of the rotating rod to rotate inside the through holes on the upper side surface of the mounting plate. When the rotating rod rotates, the traction rope is wrapped around the outer surfaces of the two ends of the rotating rod to raise the height of the pipe body under the slide rail. If the height of the pipe body is high, the power output end of the first servo motor is controlled to reverse, so that the height of the pipe body can be lowered, which is convenient for construction personnel to tow the supporting frame to adjust the position of the supporting frame. When the pipe body corresponds to the top end of the pipe jacking machine, the pipe body can be placed on the top end of the pipe jacking machine, which effectively reduces the lifting time and improves work efficiency.

[0015] By providing a sliding rail and a clamping structure, the power output of the second servo motor drives the rotation of the forward and reverse screws. Since the threaded holes on the upper ends of the two sets of sliding plates are respectively located at the forward and reverse teeth of the forward and reverse screws, the two sets of sliding plates move away from each other when the forward and reverse screws rotate, so that the clamping plates can be separated from the outer surface of the pipe body. When the pipe body is lifted, the power output end of the second servo motor is controlled to reverse, so that the clamping plates can be brought close to each other and clamp the pipe body, thereby avoiding the pipe falling due to loosening of the strapping belt, and effectively reducing the safety risk.

A pipe body 14 is arranged below the two groups of slide rails 9.

[0023] In the specific implementation process, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a group of lifting ears 15 are fixedly connected to the upper surfaces of both ends of the support frame 1, and the lifting ears 15 are convenient for connecting to a crane.

[0024] Among them, two groups of mounting frames 16 are fixedly connected to the upper surfaces of both ends of the supporting plate 2, and a mounting groove is opened on one side of each group of mounting frames 16. A pulley 17 is rotatably connected to the inner wall of the mounting groove on one side of each group of mounting frames 16. The bottom of the first servo motor 4 is fixedly connected to the upper surface of the supporting plate 2, and the pulley 17 starts the auxiliary function.

[0026] Among them, the traction ropes 8 at both ends of the rotating rods 7 in the two groups of lifting structures 3 are respectively attached to the outer surfaces of the two groups of pulleys 17 at both ends of the supporting plate 2, and the two groups of traction ropes 8 at the ends of the rotating rods 7 in the two groups of lifting structures 3 away from the rotating rods 7 are respectively fixedly connected to the upper surfaces of the two groups of slide rails 9, and the pulleys 17 play an auxiliary role in the process of winding the traction ropes 8.

[0028] Among them, one end of the positive and negative threaded rod 12 passes through the through hole on the side surface of the partition 19 and is fixedly connected to the power output end of the second servo motor 13.

The two groups of clamping plates 20 have arc grooves on opposite sides, and the two groups of clamping plates 20 are attached to the outer surface of the pipe body 14 on opposite sides. Since the threaded holes on the upper ends of the two groups of sliding plates 11 are respectively located at the positive and negative threads of the positive and negative threaded rods 12, when the positive and negative threaded rods 12 rotate, the two groups of sliding plates 11 move away from each other, so that the clamping plates 20 can be separated from the outer surface of the pipe body 14.

When the rotating rod 7 rotates, the traction rope 8 is wrapped around the outer surface of the two ends of the rotating rod 7 to raise the height of the pipeline body 14 under the slide rail 9. If the height of the pipeline body 14 is high, the power output end of the first servo motor 4 is controlled to reverse, and the height of the pipeline body 14 can be lowered, which is convenient for construction personnel to tow the carrier frame 1 to adjust the carrier frame 1, when the pipe body 14 corresponds to the top end of the pipe jacking machine, the pipe body 14 can be placed on the top end of the pipe jacking machine. When the pipe body 14 is placed on the top end of the pipe jacking machine, the construction personnel can start the second servo motor 13, and the power output rotation of the second servo motor 13 drives the positive and negative thread screw 12 to rotate. Since the threaded holes on the upper ends of the two groups of sliding plates 11 are respectively located at the positive and negative threads of the positive and negative thread screws 12, when the positive and negative thread screws 12 rotate, the two groups of sliding plates 11 are moved away from each other, so that the clamping plate 20 can be separated from the outer surface of the pipe body 14. When the pipe body 14 is lifted, the power output end of the second servo motor 13 is controlled to reverse, so that the clamping plates 20 can be close to each other and clamp the pipe body 14.
