[0002] Spring hangers are an important industrial support equipment, widely used in supporting various heavy equipment such as pipelines, valves, pumps and thermal equipment. Due to its unique adjustability and adaptability, variable spring hangers play a key role in industrial production and facilities. The spring hangers are mainly composed of springs, connecting rods, brackets and control systems. Its working principle is to change the height of the hangers by adjusting the compression of the springs to meet the needs of different equipment and pipelines.

[0003] When the spring hanger is actually used, the compression of the spring inside it is used to support the pipeline. When the variable force spring hanger is used, the spring inside it will shrink and change all the time. However, a certain amount of dust will enter the existing spring hanger when it is used. When the dust inside the spring hanger reaches a certain amount, it will cause wear to the spring and affect the spring performance.

[0027] A lifting screw 3 is movably provided inside the hanger shell 1, wherein the upper half of the lifting screw 3 is a telescopic rod to adjust the support height of the lifting screw 3. The telescopic rod is a prior art that can be clamped and fixed at multiple distances, which will not be described here.

[0028] A driving shell 7 is fixedly arranged on the outer side of the lifting screw 3, a conical ring 8 is fixedly arranged on the upper end of the baffle 4, the lower end of the driving shell 7 abuts against the upper end of the conical ring 8, two circular holes 9 are provided on the corresponding ends of the two baffles 4, and an expansion spring 10 is fixedly arranged on the corresponding side of the two circular holes 9;

[0029] Two guide grooves 501 are formed at the upper end of the guide plate 5 , and two guide rods 6 are fixedly disposed at the lower end of the baffle plate 4 . The guide rods 6 slide inside the corresponding guide grooves 501 .

[0030] The driving shell 7 is driven downward by the lifting screw 3, so that the lower end of the driving shell 7 contacts 8, and then when the upgrading screw 3 needs to work and descend, the two baffles 4 are squeezed close to each other, thereby completing the sealing of the hanger shell 1 to prevent wind, sand and rain from entering.

[0031] The cross section of the guide rod 6 is arranged in a right-angled trapezoid, and the guide groove 501 is also arranged in a right-angled trapezoid, so as to facilitate the clamping of the guide rod 6 .

[0032] A connecting plate 2 is movably provided inside the hanger shell 1 , and a lifting screw 3 is threadedly connected to the connecting plate 2 . A supporting spring 14 is fixedly provided at the lower end of the connecting plate 2 , and one end of the supporting spring 14 is fixedly connected to the inner wall of the hanger shell 1 .

[0033] Two extension blocks 11 are fixedly provided on the outer side of the connecting plate 2, and a baffle 13 is fixedly provided on the outer side of the extension block 11. Two travel grooves 12 for the extension blocks 11 to pass through are opened in the middle of the hanger shell 1. The extension blocks 11 are used to ensure that the connecting plate 2 can only slide up and down to prevent it from rotating with the lifting screw 3, and the baffle 13 is used to block dust and rainwater from entering from the travel groove 12. Through the setting of the baffle, the position of the connecting plate can also be observed to know the force condition of the support spring 14.

[0034] The lower end of the driving housing 7 is provided with a rounded corner, and the rounded corner reduces the contact area and friction when the driving housing 7 contacts the conical ring 8.

[0035] A drainage hole 15 is provided at one end of the conical ring 8, so that when it rains, the driving shell 7 blocks most of the rainwater from entering between the conical rings 8, and the drainage hole 15 is provided to discharge the rainwater accumulated between the conical rings 8, thereby preventing the rainwater from entering the interior of the hanger shell 1.

[0037] Working principle: The operator installs the hanger shell 1 at the required position, rotates the lifting screw 3, and adjusts the telescopic length of the telescopic rod to reach a suitable height, so as to adjust the height of the lifting screw 3 and the height of the driving shell 7, so that the lower end of the driving shell 7 contacts the conical ring 8, and then the conical ring 8 is squeezed and moved by the driving shell 7 through its own shape, so that the two conical rings 8 drive the two baffles 4 to approach each other, and then the two baffles 4 are merged, and then the baffle 4 seals the upper end of the hanger shell 1 to prevent dust and rainwater from entering the hanger shell 1;

[0038] When the hanger shell 1 is working, its lifting screw 3 is stressed, which in turn makes the connecting plate 2 stressed, so that it transmits the force to the supporting spring 14 to support the object. When the connecting plate 2 moves up and down, it drives the extension block 11 to move, so that the blocking piece 13 seals the travel groove 12.

[0039] When the hanger shell 1 needs to be inspected, the hanger shell 1 is removed, and then the lifting screw 3 is turned, so that the lifting screw 3 drives the driving shell 7 away from the conical ring 8, and then the baffle 4 is squeezed by the expansion spring 10, so that the two baffles 4 are squeezed apart, and then the dust and other impurities in the hanger shell 1 are cleaned to maintain the support spring 14 and other structures. When the baffle 4 moves, the baffle 4 is set by the guide rod 6, and the guide rod 6 slides inside the guide groove 501 on the guide plate 5 to limit the moving direction of the baffle 4.
