Description

Technical Field

[0001] This utility model relates to the field of cast iron pipe installation technology, specifically to a self-anchoring ductile iron pipe installation tool. Background Technology

[0002] During the installation of self-anchored ductile iron pipes, placing a sealing ring inside the pipe is a crucial step, playing a vital role in preventing media leakage and ensuring the normal operation of the system. Current technology typically involves first laying a section of ductile iron pipe in a trench, cleaning the pipe socket, manually bending the sealing ring into an approximate X-shape, and then placing it into a pre-set sealing groove in the pipe socket. After the sealing ring is installed, radial force is applied to ensure it is fully inserted into the groove. However, manually bending the sealing ring into an X-shape and placing it into the pipe is difficult to precisely control, requiring manual pressing along the entire sealing ring or tamping it with a rubber mallet. Furthermore, manually bending and placing the sealing ring is time-consuming and labor-intensive, slow, and requires workers to bend over, which is unhealthy. Utility Model Content

[0026] The mounting assembly 2 further includes an adjusting plate 21, a mounting plate 22, and an adjusting cylinder 24. The mounting plate 22 is rotatably connected to the telescopic plate 45.

[0027] The support rod 23 has a notch in the middle of one end of the mounting platform 26, and an adjusting cylinder 24 is installed in the notch. The mounting platform 26 has a U-shaped structure. The telescopic end of the adjusting cylinder 24 passes through the mounting platform 26 and is rotatably connected to a clamping wheel 25. The mounting platform 26 includes side plates 261 arranged symmetrically on both sides. A fixing box 262 is fixedly installed on the upper part of the opposite side wall of the two side plates 261. A connecting block 263 is slidably installed on the opposite side of the two fixing boxes 262. One end of the connecting block 263 extends into the fixing box 262 and is connected to the inner wall of the fixing box 262 by a clamping spring. The connecting block 263 can contact the sealing ring. When the connecting block 263 is not in contact with the sealing ring, the distance between the two connecting blocks 263 is less than the width of the sealing ring. The sealing ring is connected to the mounting platform 26 on multiple support rods 23 at multiple points, so that the sealing ring is approximately circular. Under the elastic force of the clamping spring, the two The fixed box 262 can clamp the sealing ring. Adjusting the adjustment plate 21 rotates the moving block 231, which moves radially towards the center along the arc groove 211. This causes the fixed box 262 to pull the sealing ring inward, making the sealing ring roughly X-shaped. Adjusting the telescopic end of the moving cylinder 46 moves the sealing ring towards the socket of the ductile iron pipe, aligning the sealing ring with the preset sealing position inside the ductile iron pipe. Rotating the adjustment plate 21 moves the support rod 23 radially away from the center, making the sealing ring roughly circular. Adjusting the telescopic end of the adjustment cylinder 24 extends the pressure wheel 25, causing it to contact the sealing ring and separating it from the fixed box 262. This also causes the sealing ring to contact the preset sealing position. Adjusting the adjustment plate 21 rotates the four pressure wheels 25 simultaneously along the inner wall of the sealing ring, matching the sealing ring with the preset sealing position.

[0028] The operating procedure and working principle of this device are as follows:

[0029] Move the device to the vicinity of the ductile iron pipe socket, so that the frame 11 is erected on both sides of the ductile iron pipe socket. At this time, the mounting component 2 is located outside the ductile iron pipe socket.

[0030] Adjust the adjustment plate 21 to rotate, so that the support rod 23 moves radially to a suitable position, and put the sealing ring on the mounting platform 26. Adjust the fixing box 262 to clamp the sealing ring under the elastic force of the clamping spring, so that the sealing ring is roughly circular. Adjust the adjustment plate 21 to rotate in the opposite direction, so that the fixing box 262 drives the sealing ring to retract inward, so that the sealing ring is roughly X-shaped.

[0031] According to the diameter of the ductile iron pipe socket, adjust the lifting cylinder 3 to extend or shorten its telescopic end, which drives the connecting plate 41 to move. The center of the connecting plate 41 roughly coincides with the center of the ductile iron pipe socket. The positioning clamp 47 moves to a suitable position near the ductile iron pipe socket. Adjust the two positioning clamps 47 to move away from each other, so that the positioning clamps 47 move to the outside of the ductile iron pipe socket wall. Move the frame 11 and at the same time loosen the positioning clamps 47 so that the abutment groove abuts against the ductile iron pipe socket wall.

[0032] Adjusting the telescopic end of the adjusting cylinder 46 moves the sealing ring closer to the ductile iron pipe, aligning it with the preset sealing position inside the pipe. Rotating the adjusting plate 21 moves the support rod 23 radially away from the center, making the sealing ring approximately circular. Extending the telescopic end of the adjusting cylinder 24 brings the clamping wheel 25 into contact with the sealing ring, separating it from the fixed box 262 and bringing it into contact with the preset sealing position. Rotating the adjusting plate 21 causes the clamping wheel 25 to rotate along the inner wall of the sealing ring, matching it with the preset sealing position. Adjusting the device to reset and separating it from the ductile iron pipe.
