Description

Technical Field

[0001] This invention relates to the field of pipeline laying technology, specifically to a device for laying and processing urban municipal heating pipelines. Background Technology

[0002] With the continuous improvement and development of urban infrastructure, the number and scale of heating pipelines, especially underground heating pipelines, are also increasing. However, due to factors such as environmental corrosion and improper construction, pipeline leaks occur from time to time, which has a certain impact on the safe operation of power plants and normal heating work.

[0003] While environmental factors are difficult to control, pipeline leaks caused by construction quality issues require serious attention. During construction, improper operation of pipe joints can lead to displacement deviations, causing cracks at the weld joints. Over time, this can even result in breakage and leakage. Burrs on the pipe ends make the pipe openings uneven, easily attracting dirt and impurities. Direct welding during pipe connection can affect the tightness of the joints. Under the long-term influence of hot air inside the pipe, the gaps at the pipe openings can easily lead to damage and leakage at the weld joints.

[0004] Improper connection or uneven grinding of the pipe opening can greatly affect subsequent welding work and easily lead to leakage at the weld. Summary of the Invention

[0018] The present invention has the following beneficial effects: 1. The urban municipal heating pipeline laying and processing device provided by the present invention clamps and positions the fixed pipe fittings by fixing clamps. The fixed pipe fittings are used as reference parts for the connection of two pipes. Then, the alignment part is adjusted to center the pipe fittings to be fixed. Then, the grinding mechanism contacts the pipe opening of the fixed pipe fitting. The alignment part is then adjusted to push the pipe fittings to be fixed toward the grinding mechanism. The grinding mechanism grinds the pipe openings of the two pipe fittings at the same time, so that the pipe opening end faces are flat and smooth. After grinding, the grinding mechanism moves away from the two pipe fittings. The alignment part is adjusted again to move the pipe fittings to be fixed toward the fixed pipe fittings until the pipe openings are completely connected. By cooperating with the positioning mechanism and the grinding mechanism, the problems of uneven pipe opening end faces affecting the tight fit of the pipe opening end faces and improper operation affecting the centering due to manual support connection are effectively solved, thus improving the quality of subsequent welding work.

[0019] 2. The adjustment and alignment component of this invention retracts via the second hydraulic telescopic component, causing the pipe to be fixed to slide on the mating roller assembly toward the already fixed pipe. This ensures strong overall alignment. The second hydraulic telescopic component then moves the pipe to be fixed until it contacts the opening of the already fixed pipe. The centering clamping component and the mating roller assembly then move down synchronously until the mating roller assembly retracts into the square groove. Finally, the pipe to be fixed is lowered and placed on the second mounting platform to dock with the already fixed pipe. This overall coordination improves the accuracy of alignment and has a high degree of automation.

[0020] 3. The grinding mechanism of this invention drives the grinding main component to rotate circumferentially in the front and rear vertical planes through the three rotations of the motor. It can grind the pipe openings of two pipes simultaneously and comprehensively, which saves time and improves work efficiency to a certain extent. After the pipe end face is ground smooth and flat, the grinding mechanism can be moved between the two pipes without occupying the docking space, thus avoiding affecting the pipe docking and subsequent welding work.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] See Figure 1A device for laying and processing urban municipal heating pipelines includes a positioning mechanism 1 and a grinding mechanism 2, wherein the positioning mechanism 1 is equipped with the grinding mechanism 2.

[0034] See Figure 1 , Figure 3 and Figure 8 The positioning mechanism 1 includes a movable base 11, a movable wheel set 12, a telescopic support 13, a track plate 14, a fixed clamping member 15, and an adjusting alignment member 16. The movable wheel set 12 is evenly fixedly installed on the lower end of the movable base 11. The telescopic support 13 is provided on the movable base 11. The track plate 14 is fixedly installed on the upper end of the telescopic support 13. The fixed clamping member 15 is fixedly installed on the right side of the upper end of the track plate 14. A sliding track is symmetrically opened on the upper end of the track plate 14 and on the left side of the fixed clamping member 15. The adjusting alignment member 16 is connected to the sliding track in a sliding fit manner. The grinding mechanism 2 is located between the fixed clamping member 15 and the adjusting alignment member 16.

[0035] First, the bottom of the trench at the pipe joint is flattened and compacted to form a working pit. The device is then moved into the working pit and positioned below the pipe already fixed at a designated height. Initially, all working parts of the device are clustered together, resulting in a small overall space occupied. During operation, the moving base 11 is moved by the moving wheel assembly 12. When the moving base 11 moves below the fixed pipe, the alignment member 16 moves to the left to the leftmost end of the sliding track. The telescopic support member 13 positions the device, and the track plate 14 moves upward until the fixing clamp 15 contacts the fixed pipe. The fixing clamp 15 then automatically adjusts to clamp and position the fixed pipe. At this point, the fixed pipe serves as the reference for the two pipes to be joined. Afterward, a crane is used to lift the pipe to be fixed above the trench. The device is lowered so that one end of the pipe fitting to be fixed can rest on the upper end of the adjusting and aligning component 16. Then, the adjusting and aligning component 16 is used to first center and adjust the pipe fitting to be installed. After that, the grinding mechanism 2 is unfolded and put into working position. The grinding mechanism 2 contacts the pipe opening of the fixed pipe fitting. Then, the adjusting and aligning component 16 is used to push the pipe fitting to be fixed towards the grinding mechanism 2 for contact. The grinding mechanism 2 is used to grind the pipe openings of the two pipe fittings so that the pipe opening end faces to be connected are flat and smooth. After grinding is completed, the grinding mechanism 2 is removed. The adjusting and aligning component 16 is used again to move the pipe fitting to be fixed towards the fixed pipe fitting until the pipe opening faces of the two are in contact. Then, the welding robot is used to weld the pipe seam. After welding is completed, the device is retracted again and then withdrawn from the working pit. Finally, the working pit is filled and the device is moved to the next working pit for operation.

[0036] See Figure 1 and Figure 2The telescopic support 13 includes an electric telescopic component 131, a movable receiving component 132, and a hydraulic telescopic component 133. The electric telescopic component 131 is symmetrically fixedly installed on the movable base 11. The movable receiving component 132 is fixedly installed on the upper end of the electric telescopic component 131. The movable receiving component 132 is connected to the movable base 11 by a sliding fit. The hydraulic telescopic component 133 is symmetrically fixedly installed on the upper end of the movable receiving component 132. The hydraulic telescopic component 133 is connected to the movable base 11 by a sliding fit. A track plate 14 is fixedly installed on the upper end of the hydraulic telescopic component 133. The electric telescopic component 131 drives the movable receiving component 132 downwards, ultimately causing the lower end face of the movable receiving component 132 to press against the bottom surface of the working pit. At this time, the position of the movable base 11 is fixed. The hydraulic telescopic component 133 extends upwards a certain distance, causing the fixing clamp 15 to contact the fixed pipe.

[0037] See Figure 1 , Figure 2 and Figure 6 The fixing clamp 15 includes a mounting plate 151, a mounting platform 152, a telescopic positioning component 153, a telescopic positioning component 2 154, and an arc-shaped clamp 155. The mounting plate 151 is fixedly installed on the upper right side of the track plate 14. The mounting platform 152 is fixedly installed on the upper end of the mounting plate 151. A grinding mechanism 2 is fixedly installed on the mounting platform 152. Telescopic positioning components 153 are symmetrically fixedly installed on the mounting plate 151. The telescopic positioning component 153 has a telescopic section. The upper end is fixedly installed with a telescopic positioning component 154, and the upper end of the telescopic positioning component 154 is fixedly installed with an arc-shaped clamp 155. The fixed pipe is placed on the mounting platform 152. After the telescopic positioning component 153 extends outward a certain distance, the telescopic positioning component 154 extends upward a certain distance so that the arc-shaped clamp 155 is located on both sides of the pipe. Finally, the telescopic positioning component 153 retracts inward so that the arc-shaped clamp 155 clamps and positions the fixed pipe.

[0038] See Figure 1 , Figure 2 and Figure 3 The adjustment and alignment component 16 includes an electric slider 161, a second mounting plate 162, a second hydraulic telescopic component 163, a centering clamping component 164, a second mounting platform 165, and a mating roller assembly 166. The electric sliders 161 are all connected to the sliding track in a sliding fit manner. The second mounting plate 162 is fixedly installed on the electric sliders 161. The second hydraulic telescopic component 163 is symmetrically fixedly installed on the second mounting plate 162. The centering clamping component 164 is fixedly connected to the left end of the second hydraulic telescopic component 163. The second mounting platform 165 is fixedly installed on the upper end of the second mounting plate 162. A square groove is opened on the upper end of the second mounting platform 165, and the mating roller assembly 166 is arranged in the square groove.

[0039] During operation, the electric slider 161 first slides to the left end of the sliding track, moving the mounting plate 162 to the working position and stopping for positioning. Then, the roller assembly 166 is raised and adjusted so that the upper surface of the roller assembly 166 is higher than the opening of the square groove. The crane then places the pipe to be fixed onto the upper end of the roller assembly 166. The hydraulic telescopic component 163 extends a certain distance and then the centering clamping component 164 clamps the pipe to be fixed. During the clamping process, the centering adjustment is performed simultaneously. After centering, the hydraulic telescopic component 163 drives the pipe to be fixed to move towards the fixed pipe. The pipe to be fixed first contacts the grinding mechanism 2 for grinding of the pipe end face. Then, the hydraulic telescopic component 163 drives the pipe to be fixed to move until it finally contacts the pipe opening of the fixed pipe. Then, the centering clamping component 164 and the roller assembly 166 move down synchronously to the roller assembly and retract into the square groove. Finally, the pipe to be fixed is placed on the upper end of the mounting platform 165 and docked with the fixed pipe.

[0040] See Figure 2 , Figure 4 and Figure 7 The centering clamping component 164 includes a positioning rail 1641, a first motor 1642, a bidirectional threaded rod 1643, a sliding component 1644, a telescopic positioning component 3 1645, and a special-shaped clamp 1646. The left end of the second hydraulic telescopic component 163 is fixedly connected to the positioning rail 1641. The front end of the positioning rail 1641 is fixedly mounted with the first motor 1642 via a motor mount. The bidirectional threaded rod 1643, which has two sections of threads with opposite directions on its surface, is rotatably connected in the groove of the positioning rail 1641. The front end of the bidirectional threaded rod 1643 is fixedly connected to the output shaft of the first motor 1642. The bidirectional threaded rod 1643 is symmetrically connected front and rear by threaded connections. There is a sliding component 1644, which is connected to the positioning rail 1641 by a sliding fit. The upper end of the sliding component 1644 is fixedly connected to a telescopic positioning component 1645, and the upper end of the telescopic positioning component 1645 is fixedly connected to a special-shaped clamp 1646. The side of the special-shaped clamp 1646 that contacts the pipe is a figure-eight structure with the small diameter end facing outward. The telescopic positioning component 1645 drives the special-shaped clamp 1646 to adjust its vertical position. The rotation of the motor 1642 drives the bidirectional threaded rod 1643 to rotate, so that the sliding components 1644 move closer to each other or further away from each other, so that the special-shaped clamp 1646 can clamp the pipe of a certain specification.

[0041] See Figure 2 , Figure 3 and Figure 10The mating roller assembly 166 includes a second electric telescopic component 1661, a mating concave component 1662, a fixed round rod 1663, and a roller 1664. The second electric telescopic component 1661 is uniformly fixedly installed at the bottom of the square groove. The extended ends of the second electric telescopic component 1661 are all fixedly connected to the mating concave component 1662. The mating concave component 1662 is connected to the square groove in a sliding fit. Fixed round rods 1663 are uniformly fixedly installed on the mating concave component 1662, and rollers 1664 are rotatably connected to each fixed round rod 1663. The rollers 1664 are moved upwards via the first electric telescopic component 131. Extending a certain distance causes the mating concave part 1662 to move upward, eventually exposing the square groove of the roller 1664. The pipe is first placed on the roller 1664, and then slowly retracted by the hydraulic telescopic part 2 163, causing the pipe to be fixed to slide on the roller 1664 towards the fixed pipe. The roller 1664 is used to reduce the friction of the pipe to be fixed during sliding. After the pipe ends of the two pipes are successfully connected, the telescopic positioning part 3 1645 and the electric telescopic part 2 1661 move downward synchronously, and finally the pipe to be fixed falls onto the mounting platform 2 165 and successfully connects with the fixed pipe end.

[0042] See Figure 7 The opposite ends of the mounting platform 152 and the mounting platform 165 are provided with docking grooves; the docking grooves are used to place the retracted grinding mechanism 2.

[0043] See Figure 2 , Figure 3 and Figure 5 Both mounting platform 152 and mounting platform 165 are fixedly equipped with arc-shaped anti-slip pads on their upper ends. The arc-shaped anti-slip pad on the upper end of mounting platform 165 has a square opening cut into its center to fit a square groove. (See reference...) Figure 4 and Figure 5 The irregular clamp 1646 has an anti-slip pad one fixedly installed on the end face of the contact pipe fitting, and the arc clamp 155 has an anti-slip pad two fixedly installed on the end face of the contact pipe fitting; the arc anti-slip pad, anti-slip pad one and anti-slip pad two are all used to increase the contact friction of the pipe fitting, so that it is not easy to slip after positioning.

[0044] See Figure 1 , Figure 2 , Figure 6 and Figure 9The grinding mechanism 2 includes a telescopic positioning component 21, a motor 22, a connector 23, a telescopic positioning component 24, a grinding main component 25, a motor 26, and a transmission belt 27. The telescopic positioning component 21 is fixedly installed on the fixed clamping component 15. The motor 22 is fixedly installed on the telescopic end of the telescopic positioning component 21. The output shaft of the motor 22 is fixedly connected to the connector 23. The telescopic positioning component 24 is fixedly installed on the upper end of the connector 23. The grinding main component 25 is fixedly installed on the upper end of the telescopic end of the telescopic positioning component 24. The motor 36 is fixedly installed on the telescopic end of the telescopic positioning component 24 and located below the grinding main component 25. The left end of the output shaft of the motor 36 is fixedly installed with a pulley. The pulley and the grinding main component 25 are connected by the transmission belt 27.

[0045] After one end of the fixed pipe fitting is clamped and fixed by the fixing clamp 15, the telescopic end of the telescopic positioning component 21 extends outward. The motor 22 drives the connecting component 23 to rotate upward to the 90-degree quadrant position. Then, the telescopic positioning component 24 extends upward to put the grinding main component 25 into the working position. Then, the motor 326 rotates to drive the grinding main component 25 to rotate in the front and back vertical plane circumferentially. The grinding main component 25 grinds the pipe end face that it contacts, so that the pipe end face of the two pipe fittings is smooth and flat. After grinding is completed, the grinding mechanism 2 is transferred from between the two pipe fittings in the reverse order of unfolding to avoid interfering with the subsequent welding work.

[0046] See Figure 1 , Figure 2 and Figure 9 The main grinding component 25 includes a second connecting component 251, a rotating shaft 252, a protective sleeve 253, a fourth motor 254, and a cylindrical grinding component 255. The second connecting component 251 is fixedly installed on the upper end of the telescopic positioning component 5 24. The rotating shaft 252 is rotatably connected to the second connecting component 251. A second pulley is fixedly installed on the rotating shaft 252. The second pulley and the first pulley are connected by a transmission belt 27. The protective sleeves 253 are symmetrically fixedly connected to the left and right ends of the rotating shaft 252. The fourth motor 254 is fixedly installed on the protective sleeves 253. The output shaft of motor 254 is fixedly connected to a cylindrical grinding component 255, which is rotatably connected to the protective kit 253. The height of the grinding main component 25 is adjusted by telescopic positioning component 24. When the axial height of the rotating shaft 252 is consistent with the axial height of the fixed pipe, motor 254 starts to rotate, driving the cylindrical grinding component 255 to rotate. Motor 26 rotates and drives the rotating shaft 252 to rotate circumferentially through transmission belt 27, so that the cylindrical grinding component 255 can perform comprehensive grinding on the contact pipe end face.

[0047] In specific operation: the movable base 11 is moved to directly below the fixed pipe fitting via the movable wheel set 12. The alignment adjustment piece 16 is moved to the left to the left end of the track plate 14. The movable base 11 is fixed in position via the telescopic support piece 13. The track plate 14 is pushed upward until the working end of the fixing clamp 15 contacts the fixed pipe fitting. The fixed clamp 15 then clamps and positions the fixed pipe fitting, which serves as the centering reference. The crane lifts the pipe fitting to be fixed onto the alignment adjustment piece 16, which centers the pipe fitting. The telescopic positioning piece 21 extends outward a certain length, and then... The motor 22 rotates 90 degrees, causing the connector 23 to rotate to the 90-degree quadrant position. The telescopic positioning component 5 24 moves the grinding main component 25 to the working position. The alignment component 16 is adjusted to move the pipe to be fixed towards the fixed pipe until the pipe end contacts the grinding main component 25. The motor 3 26 rotates, causing the grinding main component 25 to rotate circumferentially to grind the contacted pipe end face. After the grinding work is completed, the grinding mechanism 2 is retracted. The alignment component 16 is adjusted again to move the pipe to be fixed towards the fixed pipe until the pipe ends of the two pipes are completely fitted together, achieving docking. Then, a welding robot is used to weld the pipe joint.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
