Description

Technical Field

[0001] This invention relates to the technical field of pipeline laying, specifically to a tool for aligning and installing underground direct-buried heating pipelines and its usage method. Background Technology

[0002] With the rapid development of urbanization in my country, centralized heating has gradually become the main way to solve the heating problems of industrial production and residential life, leading to an increasing number of municipal heating pipeline networks. When heating pipelines are laid directly underground, seamless steel pipes, arc-welded or high-frequency-welded steel pipes are used. During the pipeline welding process, the quality of pipe alignment is the primary core link in welding quality control. Pipe alignment installation typically employs alignment tools, alignment frames, and lifting machinery in conjunction with manual alignment. These alignment methods are easily constrained by factors such as site conditions, climate, and pipe material type, resulting in slow construction speed, low work efficiency, and difficulty in quality control. These problems have become common challenges in the alignment installation of underground directly buried heating pipelines, affecting not only the quality control of the pipe alignment process but also the overall project schedule. Summary of the Invention

[0003] This invention addresses the shortcomings of existing tools, devices, and methods for aligning underground direct-buried heating pipelines, and proposes a tool for aligning underground direct-buried heating pipelines and its usage method.

[0004] To solve the above-mentioned technical problems, the inventors, through practice and summarization, derived the technical solution of this invention, which adopts the following technical solution:

[0005] A tool for aligning and installing underground direct-buried heating pipelines, comprising:

[0006] The frame consists of telescopic beam one and telescopic beam two, which are U-shaped structures. The two ends of telescopic beam one and telescopic beam two are spliced ​​together to form a rectangular frame.

[0007] Lifting outriggers are installed at the four corners of the rectangular frame to adjust the height of the frame.

[0008] The gripping assembly has at least two sets along the length of the frame. The gripping assembly includes a winch and a mechanical claw. The winch is installed on the frame and a steel wire rope is installed on the winch. A traveling component is installed on the top of the mechanical claw. The end of the steel wire rope is connected to the traveling component. The traveling component is used to adjust the left and right position of the mechanical claw relative to the frame. The mechanical claw is used for gripping and releasing actions.

[0009] Preferably, the telescopic beam includes an L-shaped rod one and an L-shaped rod two;

[0010] One end of the L-shaped rod is provided with a socket two, which is used to receive and fix the connecting rod, and the other end is a socket end;

[0011] The L-shaped rod has a socket at each end, one socket for receiving the connecting rod and the other socket for receiving the socket end.

[0012] The telescopic beam two includes L-shaped rod three and L-shaped rod four. One end of L-shaped rod three and L-shaped rod four are fixedly installed with a socket rod, and the socket rod and socket one / socket two are fixedly inserted.

[0013] The other end of the L-shaped rod three is provided with a socket end two, and the other end of the L-shaped rod four is provided with a socket port three that is compatible with the socket end two.

[0014] Restriction bolts are provided on socket 1, socket 2, and socket 3.

[0015] Preferably, the walking component includes a U-shaped structural plate, with two rotating shafts installed inside the U-shaped structural plate. A torsion spring is provided between the rotating shafts and the U-shaped structural plate, and a gear is installed on the rotating shaft. A mechanical claw is installed at the bottom of the U-shaped structural plate, and a transmission gear that meshes with the gear is installed on the mechanical claw. The rotating shaft, through the cooperation of the gear and the transmission gear, completes the left and right movement of the mechanical claw relative to the frame.

[0016] Preferably, a vertical rod is installed on the U-shaped structural plate, and a limiting plate is installed on the frame. The limiting plate is provided with a rectangular guide hole arranged in the horizontal direction. The top of the vertical rod is movably installed in the rectangular guide hole, and a limiting block is fitted on the vertical rod. The top and bottom of the limiting block are provided with limiting pieces. The two limiting pieces are located on the upper and lower sides of the limiting plate, and the vertical and horizontal positions of the vertical rod relative to the limiting plate are adjustable.

[0017] Preferably, one set of the gripping components is longitudinally slidable relative to the frame, and the corresponding limiting plate and winch are movably mounted on the frame;

[0018] The frame is equipped with a second winch, which has a first traction rope and a second traction rope. The ends of the first traction rope and the second traction rope are installed on corresponding limit plates. The first traction rope is used to pull the limit plate closer to another set of limit plates, and the second traction rope is used to pull the limit plate away from another set of limit plates.

[0019] The mechanical claw of the sliding gripping component holds and fixes the pipe, while the inner wall of the mechanical claw of the fixed gripping component is provided with rollers.

[0020] The two winches, with traction ropes one and two working simultaneously, are used to adjust the spacing of the mechanical claws. The vertical rod and the limit plate control the mechanical claws to maintain a horizontal state during the spacing adjustment process.

[0021] Preferably, the limiting plate includes a plate body one and a plate body two, which are laterally fitted together and whose tops are in the same plane.

[0022] A method for using a tool for aligning and installing underground direct-buried heating pipelines, the steps of which are as follows:

[0023] Step 1: Assemble the frame

[0024] Set up the alignment tool above the two sections of thermal pipes that need to be aligned during installation;

[0025] The socket rod is adapted to the corresponding socket one, the socket end two and the socket three are adapted to each other, and the socket end one and the socket one are adapted to each other.

[0026] Based on the diameter and length of the heating pipe, the expansion beam 1 and expansion beam 2 are fixed to form a frame by the limiting bolts at socket 1, socket 2 and socket 3;

[0027] Two limiting plates are installed on the frame. One limiting plate is fixed to the frame, and the other is slidably installed along the length of the frame. A fixed pulley is installed on the side of the sliding limiting plate away from the fixed limiting plate. A second winch is installed on the frame. The second winch has two winch areas. The rope winding and unwinding directions of the two winch areas are opposite. The second traction rope is connected to the side of the sliding limiting plate away from the fixed limiting plate via the fixed pulley. The first traction rope is directly connected to the side of the sliding limiting plate close to the fixed limiting plate.

[0028] Install limiting blocks in the rectangular guide holes of the two limiting plates, and install limiting pieces at the bottom and top for horizontal guidance;

[0029] A vertical rod is inserted into the limiting block, and the bottom of the vertical rod is fixed to the U-shaped structural plate. A rotating shaft and a gear are installed inside the U-shaped structural plate, and a torsion spring is installed at the rotating node of the rotating shaft.

[0030] The mechanical gripper is rotatably mounted on the U-shaped structural plate and is engaged by transmission gears and gear meshing;

[0031] Four winches are installed on the frame. The wire ropes on the four winches are connected to the corresponding rotating shafts. The two rotating shafts located on the same U-shaped structural plate rotate in opposite directions. Two of the winches are fixedly installed on the frame and correspond to the positions of the fixed limiting plates. The other two winches are slidably installed on the frame and correspond to the positions of the sliding limiting plates. These two winches can be directly installed on the rotating shafts of the sliding limiting plates.

[0032] Install corresponding lifting outriggers at the four corners of the frame. The lifting outriggers are telescopic hydraulic cylinders and have pads at the bottom.

[0033] Step 2: Grab

[0034] Four winches simultaneously release steel wire ropes, and the mechanical claws descend. After the mechanical claws descend to a height where they can clamp the heat pipes, they maintain the height of the top of the vertical rod, and the steel wire ropes are retracted. The mechanical claws are then driven to clamp and fix the heat pipes by the rotating shaft via gears and transmission gears.

[0035] Step 3: Assembly

[0036] By controlling the winding and unwinding actions and the amount of winding and unwinding of the corresponding winch, the axes of the two thermal pipes are aligned.

[0037] By adjusting the direction and rotation amount of winch two, the thermal pipeline is axially adjusted to complete the alignment of the pipeline ports.

[0038] Step 4: Separate tools and pipes

[0039] After the thermal pipeline has been aligned, the pipe ends are welded and supports are installed at the bottom.

[0040] All winches are simultaneously lowered until the mechanical claw separates from the outer ring of the pipe. The mechanical claw is then actively moved to the top of the pipe, and the vertical rod is temporarily fixed relative to the limit block. The steel wire rope is then tightened to complete the separation operation between the pipe and the mechanical claw.

[0041] Move the alignment tool to the next pipe laying location along the pipe laying direction;

[0042] Step 5: Continue laying the heating pipes in the same direction.

[0043] Repeat steps two and three until all heating pipes are laid.

[0044] Compared with the prior art, the present invention has the following beneficial effects:

[0045] The frame of this invention, formed by a combination of telescopic elements to create a rectangular frame structure, can be adaptively adjusted in size according to the length and diameter of the heating pipe, making it highly adaptable and usable. It also includes a winch and a mechanical gripper. The traction of a steel wire rope rotates the rotating shaft on the traveling component. Through gears and transmission gears, the mechanical gripper clamps the heating pipe inwards. During pipe clamping, the height of the mechanical gripper must remain constant; it only rotates without actually moving. The steel wire rope is wound around the rotating shaft and located below it, ensuring the mechanical gripper remains in a clamping state even after the pipe is lifted. Upon separation, since the pipe's position remains unchanged due to the bottom support, the steel wire rope is released, and the mechanical gripper resets under the action of a torsion spring, separating from the pipe. The mechanical gripper then actively moves upwards to detach from the pipe, and the vertical rod and limit block are temporarily fixed. The steel wire rope is then retrieved to complete the separation of the mechanical gripper and the pipe. The limit plate controls the vertical rod to slide only in the left and right and up and down directions, thereby preventing the pipeline from tilting due to the influence of the center of gravity. Secondly, it can be used in conjunction with the winch machine to perform axial alignment operations. Attached Figure Description

The lifting outriggers (30) are telescopic cylinders and have pads at the bottom. Step 2: Grab Four winches (41) simultaneously release steel wire ropes, and mechanical claws (42) descend. After the mechanical claws (42) descend to a height that can clamp the heat pipe, the height of the top of the vertical rod is maintained, the steel wire rope is retracted, and the mechanical claws (42) are driven by the rotating shaft (432) through the gear (433) and the transmission gear (422) to clamp and fix the heat pipe. Step 3: Assembly By controlling the winding and unwinding actions and the amount of winding and unwinding of the corresponding winch (41), the axes of the two thermal pipes are aligned. By adjusting the direction and rotation amount of winch two (50), the thermal pipeline is axially adjusted to complete the alignment operation of the pipeline port; Step 4: Separate tools and pipes After the thermal pipeline has been aligned, the pipe ends are welded and supports are installed at the bottom. All winches (41) are simultaneously extended until the mechanical claw (42) separates from the outer ring of the pipe. The mechanical claw (42) is actively moved to the top of the pipe. The vertical rod (44) is temporarily fixed relative to the limiting block (46). The steel wire rope is tightened to complete the separation operation between the pipe and the mechanical claw (42). Move the alignment tool to the next pipe laying location along the pipe laying direction; Step 5: Continue laying the heating pipes in the same direction. Repeat steps two and three until all the heating pipes are laid.
