Description

Technical Field

[0001] This utility model belongs to the field of ductile iron pipe technology, and relates to the butt joint installation of ductile iron pipes, especially a butt joint installation device for ductile iron pipes. Background Technology

[0002] Ductile iron pipe is a type of cast iron pipe. Through a specific process, graphite is distributed in a spherical shape, thereby improving the mechanical properties of the cast iron, such as strength, toughness, and wear resistance. When connecting adjacent ductile iron pipes, a hoisting tool is needed to lift a set of pipes. Workers then work together to insert one end of one pipe into the flared end of the other to complete the connection. Due to the poor stability of the hoisting tool, shaking frequently occurs during the connection process. Manual alignment and pipe insertion are time-consuming and labor-intensive, resulting in low connection efficiency.

[0003] To address this issue, we propose a butt-fitting installation device for ductile iron pipes. Utility Model Content

[0019] The support ring has a mounting groove in the middle, in which several rollers are rotatably mounted, suitable for installing adjacent ductile iron pipes.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This docking installation device includes a fixing component, a support component, and an expansion joint. The fixing component is fitted onto one end of the ductile iron pipe to fix the ductile iron pipe.

[0028] Example 1:

[0029] A butt-fitting installation device for ductile iron pipes, such as Figures 1 to 3 As shown, a flared end 11 is fixedly installed on one side of the ductile iron pipe 1; the docking installation device includes a fixing component 2 and a support component 3. The fixing component 2 is fitted on the outside of the ductile iron pipe 1, and the support component 3 is located on the side of the flared end 11 of the ductile iron pipe 1, which is suitable for installing adjacent ductile iron pipes 1; the fixing component 2 and the support component 3 are connected together by a pair of symmetrically arranged telescopic members 4, which can adjust the distance between the fixing component 2 and the support component 3, and is suitable for ductile iron pipes 1 of different sizes.

[0030] The fixing component 2 includes an upper fixing ring 21, a pressure ring 22, and a lower fixing ring 23. The upper fixing ring 21, the pressure ring 22, and the lower fixing ring 23 are all semi-circular structures and correspond to the arc shape of the outer surface of the ductile iron pipe 1. The upper fixing ring 21 and the lower fixing ring 23 are fitted at the connection position between the ductile iron pipe 1 and the flared mouth 11. An upper fixing ring 21 is arranged around the upper end of the ductile iron pipe 1. Several tightening screws 211 are installed on the upper fixing ring 21 at intervals. When the upper fixing ring 21 is installed on the ductile iron pipe 1, the tightening screws 211 are tightened so that the lower end of the tightening screw 211 abuts against the ductile iron pipe 1, thus fixing the ductile iron pipe 1 to the lower fixing ring 23. One end of the mounting plate 212 is respectively made at one end of the two ends of the upper fixing ring 21. The other ends of the two mounting plates 212 are respectively installed at the two ends of the pressure ring 22. The mounting plate 212 has a rectangular structure. Several bolt holes 2121 are made at intervals on the mounting plate 212 located at one end of the upper fixing ring 21 for connecting the lower fixing ring 23. The mounting plate 212 has a rectangular structure. The pressure ring 22 is located on the flared mouth 11. The two ends of the pressure ring 22 are respectively made of flat plate structure. One of them is fitted with the first lifting rod 221, and the bottom end of the first lifting rod 221 is fixedly installed on the mounting plate 212. The other is threaded with the first adjusting rod 222, and the bottom end of the first adjusting rod 222 is rotatably installed on the mounting plate 212. When the first adjusting rod 222 is rotated, the pressure ring 22 can move up and down along the first lifting rod 221. After the adjacent ductile iron pipe 1 is inserted into the flared mouth 11, the first adjusting rod 222 is rotated so that the pressure ring 22 presses the flared mouth 11 tightly, thereby increasing the friction between the flared mouth 11 and the adjacent ductile iron pipe 1 and ensuring a firm installation. The lower fixing ring 23 is arranged around the lower end of the ductile iron pipe 1. The two ends of the lower fixing ring 23 are respectively provided with mounting plates 212. The mounting plates 212 are provided with a number of bolt holes 2121 at intervals. The number and installation position of the bolt holes 2121 of the two corresponding mounting plates 212 are corresponding, which is suitable for connecting the upper fixing ring 21 and the lower fixing ring 23 together. The inner wall of the lower fixing ring 23 is provided with raised textures. The textures are perpendicular to the axial direction of the ductile iron pipe 1, which is suitable for increasing the friction between the lower fixing ring 23 and the ductile iron pipe 1, improving the installation stability, and preventing the lower fixing ring 23 from moving along the axial direction of the ductile iron pipe 1.

[0031] like Figure 1, Figure 3 As shown, the support assembly 3 includes a support ring 31 and a support platform 32. The support ring 31 is movably mounted on the support platform 32. Both the support platform 32 and the support ring 31 have a recessed semi-circular structure in the middle, and the semi-circular structure corresponds to the arc shape of the outer surface of the ductile iron pipe 1. The two ends of the support ring 31 and the two ends of the support platform 32 are movably mounted together by three second lifting rods 311 and second adjusting rods 312, so that the distance between the support ring 31 and the support platform 32 is adjustable until the top surface of the support ring 31 is at the same height as the inner surface of the flared mouth 11. The support ring 31 is adapted to support adjacent ductile iron pipes 1. Three second lifting rods 311 and one second adjusting rod 312 are located at the four corners of the support ring 31. All three second lifting rods 311 are inserted into the support ring 31, and their bottom ends are fixedly mounted on the support platform 32. The second adjusting rod 312 is threaded into the support ring 31, and its bottom end is rotatably mounted on the support platform 32, allowing the support ring 31 to move up and down along the second lifting rods 311 when the second adjusting rod 312 is rotated. A mounting groove 313 is also formed in the center of the inner side of the support ring 31. Several rollers 314 are rotatably mounted in the mounting groove 313. All rollers 314 are cylindrical in shape, facilitating the installation of adjacent ductile iron pipes 1.

[0032] like Figure 1 , Figure 2 As shown, the telescopic component 4 includes a sleeve 41, a moving rod 42, and an adjusting block 421. One end of the sleeve 41 is fixedly mounted on the side of the lower fixing ring 23. The moving rod 42 passes through the sleeve 41. The other end of the sleeve 41 has an inwardly protruding limiting ring 43 to prevent the moving rod 42 from slipping off. The sleeve 41 has a cylindrical structure, and the inner wall of the sleeve 41 is threaded. One end of the moving rod 42 is rotatably mounted on the side of the support platform 32. The other end of the moving rod 42 is located inside the sleeve 41 and is fixedly mounted with the adjusting block 421. The diameter of 1 is larger than the diameter of the moving rod 42, which is suitable for cooperating with the limiting ring 43; the outer end face of the adjusting block 421 is threaded, and the thread of the adjusting block 421 corresponds to the thread of the sleeve 41, so that when the moving rod 42 rotates, the adjusting block 421 moves inside the sleeve 41, thereby adjusting the installation length between the moving rod 42 and the sleeve 41, and finally completing the adjustment of the distance between the fixing component 2 and the support component 3. It is suitable for ductile iron pipes 1 of different sizes, or adjusting the installation position of the support component 3, so that the support component 3 can be placed on a relatively flat ground.
