[0002] Galvanized pipe is a kind of corrosion-resistant pipe, which has been widely used in the fields of construction, machinery, etc. However, during the production, transportation and use of galvanized pipe, external forces may cause the surface of galvanized pipe to deform (i.e., produce depressions).

However, when resetting the depressed part of the galvanized pipe, the lifting device can usually only lift up the depressed part of the galvanized pipe, and the deformation reset effect is poor. Even multiple bumps and depressions may be generated at the original depressed part of the galvanized pipe, which will be more prone to deformation during subsequent use. Utility Model Content

[0034] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the specification of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0035] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0036] See also Figure 1-Figure 4 The first aspect of the utility model provides a lifting mechanism, comprising: a shell 1, a main arm 2 arranged on the shell 1, and a roller 3 connected to the main arm 2; wherein the main arm 2 is arranged to be inclined to the axis of the pipe to be reset, and when the shell 1 rotates, the roller 3 will follow the rotation of the main arm 2 and move on the inner wall of the pipe to be reset, and the roller 3 abuts against the inner wall of the pipe to be reset, so as to utilize the movement of the roller 3 to lift the recessed part of the pipe to be reset and realize the reset process of the pipe to be reset. In the utility model, the axial direction refers to the direction of the central axis of rotation of the galvanized pipe, that is, the direction common to the central axis, and the pipe to be reset refers to the galvanized pipe that needs to be reset by deformation.

[0037] In some embodiments, the lifting mechanism also includes: a pushing component 4, which is connected to the main arm 2 and is used to adjust the inclination angle between the main arm 2 and the axial direction of the tube to be reset, thereby adjusting the contact angle between the roller 3 and the inner wall of the tube to be reset.

[0038] Specifically, the pushing component 4 includes an outer shell 41, a pushing member 42 arranged on the outer shell 41, and a bridging assembly 43 connected to the pushing member 42; further, the lifting mechanism also includes: a fixed seat 5, and an adjusting arm 6 connected to the fixed seat 5, wherein the adjusting arm 6 is connected to the bridging assembly 43, and the fixed seat 5 is connected to the end of the main arm 2 away from the roller 3.

[0039] Furthermore, the bridging assembly 43 includes: a bridge ring 431, a connecting seat 432 connected to the bridge ring 431, and a connecting fin 433 connected to the connecting seat 432. The housing 1 is also provided with a slide groove 11 adapted to the connecting fin 433.

[0040] In some embodiments, the connecting fin 433 is slidably connected to the slide slot 11. When the housing 1 rotates, the connecting fin 433 can be driven to rotate through the slide slot 11, thereby driving the connecting seat 432 connected to the connecting fin 433 to rotate. Furthermore, the connecting seat 432 is connected to the bridge ring 431 via a bearing, so that the connecting seat 432 can rotate in the bridge ring 431. At the same time, when the bridge ring 431 moves along the axial direction of the tube to be reset, the connecting seat 432 can be driven to move synchronously along the axial direction.

[0041] In some embodiments, the pushing member 42 is used to push the end of the adjusting arm 6 connected to the bridging assembly 43 to move along the axial direction of the tube to be reset by pushing the bridging assembly 43. Exemplarily, the pushing member 42 can be an electric push rod. When the electric push rod is extended, it pushes the connecting seat 432 and the connecting fin 433 to slide in the slide groove 11 through the bridge ring 431, thereby realizing the displacement process of the connecting seat 432.

[0042] Furthermore, one end of the main arm 2 away from the roller 3 is connected to the fixed seat 5, one end of the fixed seat 5 is hinged to the shell 41, and the other end is hinged to the adjusting arm 6, and one end of the adjusting arm 6 away from the fixed seat 5 is hinged to the connecting seat 432. By hingedly connecting the two ends of the adjusting arm 6 to the connecting seat 432 and the fixed seat 5 respectively, when the connecting seat 432 moves along the axial direction of the tube to be reset, the fixed seat 5 will rotate around the hinge with the shell 1 as the axis, thereby adjusting the angle between the fixed seat 5 and the axial direction of the tube to be reset, and then adjusting the angle between the roller 3 and the axial direction of the tube to be reset.

[0043] In some embodiments, an infrared heater 434 is further provided on the bridge ring 431. The infrared heater 434 heats the recess of the tube to be reset by radiating heat, so that the recess is more easily lifted by the lifting mechanism to improve the reset effect.

[0044] Embodiment 2

[0045] See also Figure 3 The second aspect of the utility model provides a galvanized pipe deformation restoring device, including the jacking mechanism described in the first embodiment, and also includes a power component 7, the power component 7 is connected to the shell 1, and is used to drive the shell 1 to rotate.

[0046] In some preferred embodiments, the main arm 2 and the rollers 3 connected to the main arm 2 are distributed circumferentially on the housing 1 .

[0047] It should be noted here that by adjusting the angle between the roller 3 and the axial direction of the tube to be reset, the running speed of the galvanized pipe deformation reset device in the tube to be reset can be adjusted. Specifically, when the angle between the roller 3 and the axial direction of the tube to be reset is closer to vertical, the roller 3 rotates with the shell 1, and the running speed of the galvanized pipe deformation reset device in the tube to be reset is slower. When resetting the recess of the galvanized pipe, the axial movement of the galvanized pipe deformation reset device in the tube to be reset is reduced, and the roller 3 is used to squeeze the recess multiple times to achieve the reset process. At the same time, the multiple squeezing of the roller 3 can also effectively improve the reset effect. Of course, when the galvanized pipe deformation reset device moves to the reset position in the tube to be reset, the running speed of the galvanized pipe deformation reset device in the tube to be reset can be increased by reducing the angle between the roller 3 and the axial direction, so that the galvanized pipe deformation reset device can move quickly to the reset position.

[0048] Finally, it should be noted that the embodiments of the present invention disclose only preferred embodiments of the present invention, which are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
