The utility model can complete the support processing of the inner wall of the insulated pipe body through the design of movable inner support rings, special-shaped inner support parts, receiving inner support rings, welded fins and solid circular plates, thereby avoiding the problem that the insulated pipe body is easily deformed due to pressure, and ensuring the smoothness of the medium conveyed by the insulated pipe body. Through the cooperation of the assembly plate, the first flange seat and the second flange seat, the user can install a fixed-length square cylinder between two solid circular plates for spacing the movable inner support ring. However, when the inner wall support device for installing an insulated pipe supports the insulated pipe, the diameter of the support device is relatively fixed, and it is difficult to flexibly adjust according to the insulated pipes of different inner diameters. The flexibility and practicality of use are weak, which is not conducive to universal use for different insulated pipes and has certain limitations in use.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an inner wall support device for installing an insulated pipe is proposed. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 5 As shown, an inner wall support device for installing an insulated pipe includes a covering tube 1, four through cavities 2 are evenly distributed around the outer surface of the covering tube 1, positioning grooves 3 are evenly distributed in an annular direction on the right side of the surface of the covering tube 1, a supporting mechanism 4 is arranged inside the covering tube 1, and a locking mechanism 5 is arranged on one side of the surface of the supporting mechanism 4.

[0025] By adopting the above technical solution, the support mechanism 4 can adjust the diameter of the entire support device and flexibly adjust the support diameter of the support device;

[0026] The locking mechanism 5 can lock the adjusted support size of the supporting mechanism 4 to prevent the position of the supporting mechanism 4 from becoming loose and changing due to a secondary rotation.

[0027] Furthermore, the supporting mechanism 4 includes a bidirectional screw rod 401 rotatably arranged on the inner surface of the covering tube 1 , both ends of the surface of the bidirectional screw rod 401 are connected with a movable ring 402 through threads, and the right end of the bidirectional screw rod 401 passes through the covering tube 1 and is fixedly installed with a hand wheel 405 .

[0028] By adopting the above technical solution, the hand wheel 405 can be easily manually screwed to rotate the bidirectional screw rod 401.

[0029] Furthermore, the support mechanism 4 also includes four support rods 403 evenly distributed around the surface of the moving ring 402 and rotatably arranged through a rotating shaft seat, and two upper ends of the support rods 403 corresponding to each other laterally penetrate the through cavity 2 and are rotatably arranged with support plates 404 through the same rotating shaft seat.

[0030] By adopting the above technical solution, the through cavity 2 limits the movable ring 402 through the support rod 403, so that when the bidirectional screw rod 401 rotates, the movable rings 402 on both sides can move in opposite or reverse directions by pushing with threads;

[0031] The distance between the moving rings 402 is reduced, and the upper end of the support rod 403 is pushed outward obliquely, pushing the support plate 404 to expand;

[0032] On the contrary, the moving rings 402 move away from each other, and by pulling the support rod 403 to shrink toward the inside of the covering tube 1, the support plate 404 is pulled to shrink;

[0033] Furthermore, the locking mechanism 5 includes a fixing plate 501 fixedly installed on the front side of the surface of the hand wheel 405 , and a locking pin 502 is slidably provided through the middle of the surface of the fixing plate 501 .

[0034] By adopting the above technical solution, the thickness of the fixing plate 501 is half of the thickness of the hand wheel 405 , and the protruding portion of the right end of the locking pin 502 does not exceed the right side surface of the hand wheel 405 .

[0035] Furthermore, the locking mechanism 5 also includes a ring plate 503 fixedly installed on the left side of the surface of the locking pin 502 , and a spring 504 is fixedly installed on the right side of the surface of the ring plate 503 and sleeved on the periphery of the locking pin 502 . The right end of the spring 504 is fixedly connected to the fixing plate 501 .

[0036] By adopting the above technical solution, the locking pin 502 is inserted into the positioning groove 3 at the nearest corresponding point, and the positioning groove 3 is used to limit the hand wheel 405, so that the hand wheel 405 cannot be rotated a second time, thereby locking the entire support mechanism 4.

[0037] Furthermore, a magnetic attraction plate 6 of the same size and shape is fixedly provided on the right side of the surface of the hand wheel 405 , and a metal plate 7 is fixedly installed on the left end of the bidirectional screw rod 401 passing through the covering tube 1 .

[0038] By adopting the above technical solution, the magnetic plate 6 can be adsorbed with the metal plate 7, and the supporting device can be flexibly adapted and assembled according to the length of the insulation pipe.

[0039] Furthermore, a groove 8 is provided on the left side of the surface of the metal plate 7 , and the shape, size and depth of the groove 8 match the shape, size and thickness of the magnetic attraction plate 6 .

[0040] By adopting the above technical solution, the shapes of the magnetic plate 6 and the groove 8 are nested with each other, and the support mechanisms 4 in the assembled multiple support devices can be adjusted synchronously by adjusting the support mechanism 4 of the first support device.

[0041] Working principle: When using the inner wall support device for installing the thermal insulation pipe, first, according to the specific length of the thermal insulation pipe, prepare an appropriate number of support devices, insert the magnetic suction plate 6 of the support device into the surface groove 8 of the metal plate 7 of another support device, and then remove the locking mechanism 5 on the surface of the support device that is assembled subsequently, and only retain the locking mechanism 5 of the front end support device, and then pull out the locking pin 502 in the front end support device, and turn the hand wheel 405. The hand wheel 405 limits the movable ring 402 through the support rod 403 in the through cavity 2, so that the movable ring 402 moves in the opposite or reverse direction. As the distance between the movable rings 402 is reduced, the upper end of the support rod 403 is pushed outward obliquely, pushing the support plate 404 to expand. On the contrary, the movable rings 402 move away from each other, and by pulling the support rod 403 to shrink toward the inside of the covering tube 1, the support plate 404 is pulled to shrink. According to the thermal insulation pipe The inner diameter of the channel can be adapted and adjusted so that the support plate 404 can fit the inner wall of the insulation pipe. The shapes of the magnetic suction plate 6 and the groove 8 are nested with each other. The support mechanism 4 in the assembled multiple support devices can be adjusted synchronously by adjusting the support mechanism 4 of the first support device, that is, the entire assembled multiple support devices can be adjusted at one time, and the support is expanded synchronously. After adjusting to the appropriate support size, the locking pin 502 is released. Under the driving force of the spring 504, the locking pin 502 is driven through the ring plate 503 to insert the locking pin 502 into the positioning groove 3 at the nearest point, thereby positioning the hand wheel 405 so that the hand wheel 405 cannot be rotated for the second time, which locks the entire support mechanism 4 to prevent the secondary rotation from causing the support mechanism 4 to loosen and change its position, so that the entire support device can support the insulation pipe more stably and effectively. This is the working principle of the inner wall support device for the installation of the insulation pipe.
