[0002] Ductile iron pipes refer to pipes that are centrifugally cast at high speed by a centrifugal ductile iron casting machine after adding a spheroidizing agent to molten cast iron numbered 18 or above. Ductile iron pipes, with the essence of iron and the properties of steel, as well as excellent anti-corrosion and ductility properties, are widely used in water supply, gas transmission and other systems.

[0003] One end of an existing single-section ductile iron pipe is a socket end, and the other end is a spigot end that mates with the socket end. Currently, when installing ductile iron pipes, mechanical equipment such as excavators is often used to insert the spigot end of the next section of ductile iron pipe into the socket end of the previously installed ductile iron pipe.

[0004] However, this installation method has the following problems: 1. The operation of mechanical equipment requires professional skills and rich experience, and the operation is complex. Non-professional personnel may cause low installation efficiency or even safety accidents; 2. Improper operation of mechanical equipment or inaccurate equipment accuracy may cause damage to the surface of ductile iron pipes, such as bumps and scratches. These damages not only affect the appearance of the pipes, but may also shorten their service life and reduce the sealing performance; 3. Mechanical equipment may have limitations in fine adjustment and precision control, which may lead to inaccurate pipe docking, thereby affecting the stability and reliability of the entire pipe system; 4. Mechanical equipment requires regular maintenance to ensure its performance and service life, which not only increases the economic cost, but also increases the time cost.

[0040] See Figure 1, a ductile iron pipe installation device provided by an embodiment of the present application includes a bearing seat 11 for contacting the end face of the first socket end 101 of the first pipe 10. The bearing seat 11 is supported on the first pipe 10 through a support member 12. Two hoists 13 are connected to the bearing seat 11. The two hoists 13 are respectively arranged on both sides of the first socket end 101. The two hoists 13 are respectively connected to a binding member 15 through steel wires 14. The binding member 15 is used to connect to the second pipe 16 adjacent to the first pipe 10.

[0041] See Figure 1 , the first pipe 10 refers to one section of the ductile iron pipe. The two ends of the first pipe 10 are respectively a first socket end 101 and a first insertion end. Among them, the external dimension of the first socket end 101 is larger than that of the first insertion end. The bearing seat 11 is used to contact the end face of the first socket end 101 to bear the load transmitted from the hoist 13 and transmit the load to the first pipe 10. The support member 12 is supported on the first pipe 10 and connected to the bearing seat 11, so as to keep the bearing seat 11 at a certain height. The hoist 13 is connected to the bearing seat 11 and is used to provide tension during the installation process. Among them, the hoist 13 can include an electric hoist or a manual hoist. When in use, the retraction and extension of the chain of the hoist 13 are controlled by an electric drive device or manually. Exemplarily, the installation height of the hoist 13 is roughly consistent with the height of the center line of the first pipe 10. The two hoists 13 are symmetrically arranged on both sides of the first socket end 101 along the center line of the first pipe 10. The two hoists 13 are respectively connected to a binding member 15 through steel wires 14. The binding member 15 is used to bind on the second pipe 16. Exemplarily, the binding member 15 can include a pipe clamp, a noose or a rope. The second pipe 16 refers to another section of the ductile iron pipe adjacent to the first pipe 10. The two ends of the second pipe 16 are respectively a second socket end 161 and a second insertion end. Among them, the external dimension of the second socket end 161 is larger than that of the second insertion end. When the binding member 15 is bound on the second pipe 16, the second socket end 161 can be used for limiting to prevent the binding member 15 from detaching from the second pipe 16.

[0042] The ductile iron pipe installation device provided by the embodiment of the present application is used to install two adjacent sections of ductile iron pipes together. The specific installation process is as follows:

[0043] The load-bearing seat 11 is supported on the first pipe 10 through the support member 12 and contacts the end face of the first socket end 101. The bundling member 15 is bundled on the second pipe 16. Two hoists 13 are respectively arranged on both sides of the first socket end 101 and connected to the load-bearing seat 11. Then each hoist 13 is connected to the bundling member 15 through a steel wire rope 14, wherein the two steel wire ropes 14 are respectively located on both sides of the first pipe 10. Then, control the retraction and release of the chains of the two hoists 13 to move the second pipe 16 towards the first pipe 10 until the first insertion end of the first pipe 10 is completely inserted into the second socket end 161 of the second pipe 16.

[0044] The ductile iron pipe installation device provided by the embodiment of the present application is simple to operate, reduces the requirements for operators, and helps improve the construction efficiency. During the installation process, the magnitude of the pulling force, the direction of the pulling force, and the moving speed of the pipe can be flexibly controlled according to the specific installation scenario and requirements, which helps improve the installation accuracy of the pipe. It is applicable to various site conditions and can play a role whether in a spacious construction area or a relatively narrow space. It does not require regular maintenance and upkeep, reduces the economic cost, and avoids affecting the project progress due to maintenance.

[0045] The load-bearing seat 11 can be a frame structure welded by steel sections. The frame structure contacts the end face of the first socket end 101 and is supported on the first pipe 10 through the support member 12 to bear the load transmitted from the hoist 13.

[0046] In some embodiments, referring to Figure 2 , the load-bearing seat 11 includes a cross beam 111 that is horizontally arranged and connected to the support member 12. The cross beam 111 is used to contact the end face of the first socket end 101. Exemplarily, the cross beam 111 is horizontally arranged and connected to the support member 12, and then the cross beam 111 is supported on the first pipe 10 through the support member 12. The cross beam 111 also contacts the end face of the first socket end 101, and both ends of it are respectively connected to the two hoists 13, and then the cross beam 111 is used to bear the load transmitted from the hoist 13. For example, the cross beam 111 can be made of steel sections such as square pipes and I-beams. The installation height of the cross beam 111 is generally consistent with the height of the center line of the first pipe 10.

[0047] The cross beam 111 can directly contact the end face of the first socket end 101. However, during the installation process of the cross beam 111, if the cross beam 111 collides with the end face of the first socket end 101, the end face of the first socket end 101 may be damaged. In order to avoid damaging the end face of the first socket end 101, in some embodiments, referring to Figure 2, the crossbeam 111 is used to contact the end face of the first socket end 101 through the crossbeam buffer pad 112. By providing the crossbeam buffer pad 112, it is used to protect the end face of the first socket end 101 to prevent the crossbeam 111 from directly contacting the end face of the first socket end 101 and damaging the end face of the first socket end 101. Exemplarily, the crossbeam buffer pad 112 may include a wooden cushion block or a rubber pad.

[0048] The crossbeam 111 can be directly connected to the hoist 13 through fasteners such as bolts. In some embodiments, refer to Figure 2 , both ends of the crossbeam 111 are respectively connected to the hoist 13 through the ear plates 113. Exemplarily, the ear plates 113 can be made of steel plates, which can be welded to the crossbeam 111 or connected through fasteners such as bolts. Through holes are provided on the ear plates 113, and the hoist 13 can be connected to the through holes of the ear plates 113 through hooks.

[0049] In some embodiments, refer to Figure 2 , the support member 12 includes a support portion 121 for supporting on the top of the first socket end 101 and a connecting portion 122 connected between the support portion 121 and the load-bearing seat 11. Exemplarily, the support portion 121 is connected to the crossbeam 111 of the load-bearing seat 11 through the connecting portion 122, and the support portion 121 and the connecting portion 122 are substantially in an L-shaped structure after being connected. When installing the load-bearing seat 11, only need to make the crossbeam 111 contact the end face of the first socket end 101 and make the support portion 121 support on the top of the first socket end 101. For example, both the support portion 121 and the connecting portion 122 can be made of section steels such as channel steels, angle steels or I-beams.

[0050] In order to improve the reliability and stability of the support of the support member 12, in some embodiments, refer to Figure 2 , there are two support portions 121, and the two support portions 121 are used to be respectively arranged on both sides of the center line of the first pipeline 10. Among them, the two support portions 121 can be connected to the crossbeam 111 through the same connecting portion 122, or can be respectively connected to the crossbeam 111 through a connecting portion 122.

[0051] The support portion 121 can directly support on the top of the first socket end 101, but during the installation of the ductile iron pipeline, if the support portion 121 shakes on the top of the first socket end 101, it may damage the top of the first socket end 101. In order to avoid damaging the top of the first socket end 101, in some embodiments, refer to Figure 2 , the support portion 121 is used to support on the top of the first socket end 101 through the support buffer member 123. Exemplarily, the support buffer member 123 may include a wooden cushion block or a rubber pad.

[0052] In some embodiments, a protective rubber hose is sleeved on the wire rope 14. By providing the protective rubber hose on the wire rope 14, during the installation process of the ductile iron pipe, it can prevent the wire rope 14 from contacting the surface of the pipe and damaging the pipe surface.

[0053] As mentioned above, the above are only the preferred embodiments of the present application, and there is no limitation in any form to the present application. According to the technical essence of the present application, within the spirit and principle of the present application, any simple modification, equivalent replacement, and improvement made to the above embodiments still fall within the protection scope of the technical solution of the present application.
