Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connectors, in particular to a settlement universal telescopic compensation joint assembly. Background Art

[0002] Pipe connectors are parts used in construction and industrial production to connect and fix pipeline systems to ensure that fluids or gases can be transmitted smoothly in the pipeline. The universal telescopic compensation joint is one of the important components of pipe connectors. It is a special pipe connector that can provide compensation when the pipeline system settles, thereby avoiding bending damage caused by settlement.

[0003] A Chinese patent discloses a settlement universal telescopic compensation joint (authorization announcement number CN219841217U). The patented technology includes two universal joints, which include a spherical shell, a universal ball and a flange. The universal ball is installed inside the spherical shell, and the flange is fixed to the connecting end of the spherical shell. When settlement occurs and causes angular deflection, one end of the pipeline sinks and deforms, the first universal ball performs angular deflection, and the second universal ball performs reverse angular deflection at the same time, which can be quickly adapted to compensate for the settlement deformation and avoid bending damage caused by settlement of the pipeline. When settlement occurs and causes the pipeline to be stretched, when one end settles, the product structure can be lengthened, and the limiting telescopic tube is lengthened in the telescopic shell to compensate for the deformation of the pipeline. By setting a limiting structure, it is ensured that the limiting telescopic tube will not separate from the telescopic shell during lengthening.

[0004] However, most existing universal telescopic compensating joints utilize a universal ball that rotates within a flange to achieve adjustment. This rotation can cause wear to the internal packing, impacting performance. For example, the aforementioned reference document utilizes a universal ball that rotates within a flange. In practice, this rotation wears the packing, requiring the flange and universal ball to be disassembled for refilling, impacting efficiency. Therefore, those skilled in the art have provided a subsidence universal telescopic compensating joint assembly to address the issues raised in the aforementioned background art.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-4 The utility model provides a technical solution for a subsidence universal telescopic compensation joint assembly, which includes: a flange 1, a universal ball 2 rotatably arranged at one end of the flange 1, a connecting piece 21 installed at one end of the universal ball 2, and a first connecting pipe 3 connected to one end of the connecting piece 21. A second connecting pipe 4 is arranged on the outside of the first connecting pipe 3, an oil cylinder 5 is installed on the outer surface of the second connecting pipe 4, a motor 51 is installed at the middle position of the upper surface of the oil cylinder 5, an inner cylinder 54 is arranged inside the oil cylinder 5, and the driving end of the motor 51 is connected to a rotating shaft 51 inside the inner cylinder 54. 1. A rotating rod 512 is symmetrically arranged on the outside of the rotating shaft 511. A heating tube 56 is symmetrically arranged on the outside of the inner tube 54 inside the oil cylinder 5. A first feed tube 53 is also installed on the outside of the oil cylinder 5. A liquid outlet pipe 52 is installed on the lower surface of the oil cylinder 5. This arrangement utilizes the inner tube 54 inside the oil cylinder 5 to store lubricating oil, and the lubricating oil can be discharged to the sealing rubber 7 through the liquid outlet pipe 52. The sealing rubber 7 is provided with micropores for the entry of lubricating oil. In this way, lubrication between the sealing rubber 7 and the first connecting tube 3 and the second connecting tube 4 can be achieved, thereby reducing wear.

[0024] A packing cylinder 6 is installed on the outer surface of the flange 1, and an inner packing 63 is provided inside the packing cylinder 6. An electric telescopic rod 62 is installed on the upper surface of the packing cylinder 6. The telescopic end of the electric telescopic rod 62 is connected to a pressure plate 621 inside the packing cylinder 6. This setting utilizes the operation of the electric telescopic rod 62 to cause the pressure plate 621 to move downward inside the packing cylinder 6, and then the inner packing 63 inside it can be squeezed into the built-in packing 11 inside the flange 1, thereby achieving the purpose of timely replenishment.

[0025] like Figure 2 As shown, a second feed pipe 64 is installed on the outside of the filling cylinder 6, and a sealing cover is threadedly connected to the outer end of the second feed pipe 64. This arrangement can seal the second feed pipe 64 using the sealing cover to facilitate the purpose of sealing the filling cylinder 6.

[0026] like Figure 2 As shown, a discharge pipe 61 is fixed to the lower surface of the stuffing cylinder 6, and the lower end of the discharge pipe 61 is connected to the upper surface of the flange 1. The radius of the pressure plate 621 is smaller than the radius of the discharge pipe 61, and the lower surface of the pressure plate 621 is in contact with the stuffing 63 in the cylinder. This arrangement utilizes the discharge pipe 61 to squeeze the stuffing 63 inside the stuffing cylinder 6 into the interior of the built-in stuffing 11.

[0027] like Figure 4 As shown, the inner side of the flange 1 is filled with a built-in filler 11 outside the universal ball 2, and the outer wall of the universal ball 2 is in contact with the built-in filler 11. This setting utilizes the built-in filler 11 to achieve contact with the universal ball 2, thereby achieving the purpose of rotating sealing of the universal ball 2 inside the flange 1.

[0028] like Figure 4As shown, a sealing rubber 7 is provided on the inner side of the second connecting pipe 4 , and the outer surface of the first connecting pipe 3 contacts the inner side of the sealing rubber 7 .

[0029] like Figure 3 As shown, a heat insulating layer 55 is also provided on the inner side of the oil cylinder 5, and at least six heating tubes 56 are symmetrically provided inside the oil cylinder 5. This arrangement utilizes the heating tubes 56 to heat the inside of the oil cylinder 5, so as to heat the oil inside the inner cylinder 54 to prevent it from solidifying and affecting its use.

[0030] The working principle of the present invention is as follows: when the built-in stuffing 11 inside the flange 1 needs to be supplemented, the filler to be filled is first fed into the interior of the stuffing cylinder 6 from the second feed pipe 64, and the second feed pipe 64 is sealed by the sealing cover after entering. When filling, the electric telescopic rod 62 is activated to move the pressure plate 621 inside the stuffing cylinder 6, so that the stuffing 63 in the cylinder can be fed downward through the discharge pipe 61 to supplement the built-in stuffing 11. When supplementing, the universal ball 2 can be shaken to supplement the stuffing 63 in the cylinder to the missing position, without the need to disassemble the flange 1 and the universal ball 2 to supplement the built-in stuffing 11.

[0031] At the same time, in order to avoid the first connecting tube 3 and the second connecting tube 4 from causing wear on the inner side of the sealing rubber 7 when they move, the lubricating oil inside the inner cylinder 54 can be passed into the sealing rubber 7 through the liquid outlet pipe 52, thereby achieving the purpose of lubrication and sealing, and improving the service life of the sealing rubber 7. In addition, the motor 51 can be used to rotate the rotating rod 512 outside the rotating shaft 511 to stir the lubricating oil inside it, and the heating tube 56 can be used for heating to prevent the lubricating oil from solidifying and affecting the subsequent use. The structure is simple and practical.

[0032] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention.
