Description

Technical Field

[0001] This utility model relates to the field of socket steel pipe technology, and in particular to a device for assisting in the installation of socket steel pipe sealing rings. Background Technology

[0002] Socket pipes are pipe fittings that connect pipes by nesting a socket and a spigot. They form stable joints using welding, threading, or rubber ring sealing methods. Their structural types include tees, elbows, and reducers. According to the connection method, they can be divided into socket welding, butt welding, threaded connection, and flexible double-fusion socket connection. Socket pipe fittings are made of materials such as carbon steel, stainless steel, alloy steel, and PPR plastic.

[0003] Currently, when connecting socket steel pipes, a sealing ring needs to be fitted onto one end of the steel pipe to achieve a sealing effect at the joint of the two socket steel pipes. However, the installation of the sealing ring is mostly done manually by the workers, who fit it onto the outer surface of the socket steel pipe, which results in low efficiency in fitting the sealing ring onto the steel pipe. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the prior art: the installation of sealing rings is mostly done manually by workers, who put them on the outer surface of the socket steel pipe, which results in low efficiency of sealing ring fitting onto the steel pipe and reduces efficiency. Therefore, the proposed auxiliary installation device for socket steel pipe sealing rings is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An auxiliary device for installing a socket steel pipe sealing ring includes a ring and hinge plates, wherein multiple hinge plates are arranged in a ring array and hinged to one side of the ring; A support rod is fixedly connected to the ring, and multiple hydraulic rods are arranged in a ring array on the support rod. The end of each hydraulic rod away from the support rod is slidably connected to the inner wall of the hinge plate. The ring is equipped with multiple cleaning components, including an arc-shaped box and an airbag. The airbag is fixedly connected to one of the hinge plates. One end of the arc-shaped box is fixedly connected to one side of the ring. The end of the airbag away from the hinge plate is connected to the arc-shaped box. An exhaust port is provided on the side wall of the arc-shaped box away from the ring.

[0006] Preferably, a cylinder is fixedly connected to the end of the support rod away from the ring, and square boxes are fixedly connected to both ends of the cylinder. A piston plate is slidably connected to the end of the square box away from the cylinder.

[0007] Preferably, the piston plate has an arc-shaped plate at the end away from the cylinder, and a spring is fixedly connected between the arc-shaped plate and the outer wall of the square box.

[0008] Preferably, an elliptical cylinder is fixedly connected to the outer wall of the support rod, an extrusion plate is slidably connected inside the elliptical cylinder, and a connecting pipe is fixedly connected between the elliptical cylinder and the cylindrical cylinder.

[0009] Preferably, a rotating shaft is rotatably connected to the side wall of the annulus, one end of the rotating shaft is rotatably connected inside the elliptical cylinder, and the outer surface of the rotating shaft inside the elliptical cylinder is threaded, and the rotating shaft is threadedly connected to the extrusion plate.

[0010] Preferably, a handle is fixedly connected to the end of the rotating shaft away from the elliptical cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The shaft is rotated by the handle. When the shaft rotates, it can drive the extrusion plate to move inside the elliptical cylinder and push the gas inside the elliptical cylinder into the cylindrical cylinder through the connecting pipe. The gas then enters the square boxes on both sides of the cylindrical cylinder. The gas in the square boxes pushes the piston plate to move. When the two piston plates move away from each other, they are respectively squeezed onto the inner wall of the socket steel pipe, thus achieving the stability between the device and the socket steel pipe.

[0012] 2. Simultaneously drive multiple hydraulic rods, which extend and push the connected hinge plates to rotate around the hinge point with the ring as the fulcrum. During the rotation of the hinge plates, the air bladder is squeezed, and the gas in the air bladder enters the arc-shaped box and is discharged to the outer surface of the socket steel pipe through the exhaust port, blowing off the dust and dirt attached to the socket steel pipe.

[0013] 3. When the diameter of the end of the multiple hinge plates away from the ring is the same as the outer diameter of the socket steel pipe, the hinge plates are in contact with the end of the socket steel pipe. Then, push the sealing ring on the ring. The sealing ring slides down the hinge plates to the cleaned outer surface of the socket steel pipe to facilitate the connection of multiple socket steel pipes. Attached Figure Description

[0019] Reference Figures 1-2 , Figure 4 A support rod 12 is fixedly connected to the ring 1. Multiple hydraulic rods 6 are arranged in a ring on the support rod 12. The end of the hydraulic rod 6 away from the support rod 12 is slidably connected to the inner wall of the hinge plate 11. The extension of the hydraulic rod 6 can push the hydraulic rod 6 to rotate with the hinge point of the ring 1 as the fulcrum. Multiple cleaning components are installed on the ring 1. The cleaning components include an arc-shaped box 2 and an airbag 13. The airbag 13 is fixedly connected to one of the hinge plates 11. One end of the arc-shaped box 2 is fixedly connected to one side of the ring 1. Multiple arc-shaped boxes 2 are arranged in a ring on the ring 1 and are respectively located on one side of the hinge plate 11. The end of the airbag 13 away from the hinge plate 11 is connected to the arc-shaped box 2. An exhaust port is opened on the side wall of the arc-shaped box 2 away from the ring 1.

[0020] Reference Figures 1-2 The end of the support rod 12 away from the ring 1 is fixedly connected to a cylinder 10. The two ends of the cylinder 10 are respectively fixedly connected to a square box 7. The end of the square box 7 away from the cylinder 10 is slidably connected to a piston plate 8. The end of the piston plate 8 away from the cylinder 10 is provided with an arc plate. A spring 9 is fixedly connected between the arc plate and the outer wall of the square box 7. The outer surface of the arc plate can fit against the inner wall of the receiving steel pipe.

[0021] Reference Figures 2-3An elliptical cylinder 4 is fixedly connected to the outer wall of the support rod 12. An extrusion plate 15 is slidably connected inside the elliptical cylinder 4. A connecting pipe 5 is fixedly connected between the elliptical cylinder 4 and the cylinder 10. A rotating shaft 3 is rotatably connected to the side wall of the ring 1. One end of the rotating shaft 3 is rotatably connected inside the elliptical cylinder 4. The outer surface of the rotating shaft 3 inside the elliptical cylinder 4 is threaded. The rotating shaft 3 is threadedly connected to the extrusion plate 15. A handle 14 is fixedly connected to the end of the rotating shaft 3 away from the elliptical cylinder 4. The connection method between the rotating shaft 3 and the extrusion plate 15 is similar to the connection relationship between the lead screw and the slider in the prior art.

[0022] In this utility model, as shown in the appendix Figure 1 As shown, firstly, the sealing ring is fitted onto the outer surface of the ring 1, and then the cylinder 10 is placed inside the socket steel pipe. The handle 14 drives the rotating shaft 3 to rotate. When the rotating shaft 3 rotates, it can drive the extrusion plate 15 to move inside the elliptical cylinder 4, and push the gas inside the elliptical cylinder 4 into the cylinder 10 through the connecting pipe 5. The gas then enters the square boxes 7 on both sides through the cylinder 10. The gas in the square boxes 7 pushes the piston plate 8 to move.
