[0025] The following embodiments can be understood as a part of the local structure or method of the present invention, or as a combination of embodiments to explain the connotation of a larger range of structures or methods of the present invention.

[0026] A galvanized steel pipe grooved auxiliary support device, such as Figure 1 As shown, the system includes a base 1, supporting legs 2, a telescopic mechanism 3, a platform 4, and a lateral support mechanism. The base 1 has supporting legs 2 at its bottom end. The base 1 is connected to the platform 4 via the telescopic mechanism 3. The platform 4 has a first roller assembly at its top and lateral support mechanisms on both sides, each with a second roller assembly. The first roller assembly constrains and supports the steel pipe 13 from the bottom, while the second roller assembly constrains and supports the steel pipe 13 from the sides, thus ensuring the stability of the steel pipe during the grooving process.

[0027] like Figures 1-3 As shown, the first roller assembly and the second roller assembly are each provided in two sets along the front-to-back direction, and the two sets of the first roller assembly or the second roller assembly in the front-to-back direction are at the same height. When the platform is horizontal, the outer wall of the steel pipe is in contact with the top of both the first roller assembly and the second roller assembly. At this time, the axis of the steel pipe is also in a horizontal state. This arrangement ensures that the support height provided is appropriate and the axis of the steel pipe is horizontal when connecting the steel pipe to the grooving machine, ensuring that the steel pipe is subjected to uniform force, thereby improving the grooving quality.

[0028] like Figure 1As shown, the base bottom end is uniformly distributed with 3 or 4 support legs, the support leg is an adjustable height support leg, and the base top end is also provided with a level. When encountering uneven construction ground, the base can be leveled by adjusting the length of the support leg, and the platform is also leveled when the base is leveled, that is, the base and the platform are parallel to each other.

[0029] As shown in Figure 1 , the telescopic mechanism is a first electric control telescopic device, the fixed end of the first electric control telescopic device penetrates the base 1 and is fixedly connected with the base 1, and the telescopic end is fixedly connected with the center position of the bottom of the platform 4. The first electric control telescopic device is used to realize platform height adjustment.

[0030] As shown in Figure 1 , the first electric control telescopic device is an electric cylinder or a hydraulic cylinder or a pneumatic cylinder.

[0031] As shown in Figure 1 , 2 , and 3, the top end of the platform 4 is provided with two groups of through strip grooves A in the front-rear direction, each group of strip grooves A includes left-right symmetrical strip groove one 41 and strip groove two 42, the first roller assembly includes roller base one 11 arranged at the strip groove one 41 and the strip groove two 41 respectively, the top end of the roller base one 11 is provided with a first roller 12, and the bottom end of the roller base one 11 is provided with a threaded hole one, which is fixedly connected with the strip groove one 41 or the strip groove two 42 through a positioning bolt one 14. That is, the first roller can move left and right along the strip groove one or the strip groove two, and when adjusted to the appropriate position, it is fixed through the positioning bolt one, so as to adapt to steel pipe supports of different outer diameters.

[0032] As shown in Figure 1 , the left-right ends of the platform 4 are symmetrically provided with inclined support plates 5, and the lateral support mechanism is connected with the inclined support plates 5.

[0033] As shown in Figure 1 , 2 , and 3, the lateral support mechanism includes two groups of through strip grooves B opened on the inclined support plates 5 in the front-rear direction, each group of strip grooves B includes one strip groove three 51, the front-rear ends of the inclined support plates 5 are also provided with strip groove fours 8 penetrating the strip groove three 51 respectively, each strip groove three 51 is provided with a second roller 10, the second roller 10 is connected with a roller base two 9 through a roller support, the roller base two 9 is connected with the strip groove three 51 through a second electric control telescopic device 6, the fixed end of the second electric control telescopic device is slidingly connected with the strip groove three 51, the outer wall of the fixed end is provided with a threaded hole two, and the strip groove four 8 is provided with a positioning bolt two 7 penetrating the strip groove four and screwing with the threaded hole two. Similarly, the second roller can move along the strip groove three, and is fixed through the positioning bolt two after reaching the appropriate position.

[0034] As Figure 1 shown, the second electric control telescopic device 6 is an electric cylinder or a hydraulic cylinder or a pneumatic cylinder.

[0035] The working principle of the new type is as follows: Figure 1 As shown in the figure, one end of the steel pipe is connected with the press groove machine, and the new type is used to support the other end of the steel pipe. The height-adjustable supporting legs are used to level the base, and the platform is in a horizontal posture after the base is leveled. The spacing of the first rollers and the spacing of the second rollers are adjusted to adapt to steel pipes of different outer diameters. The front and rear groups of first rollers and second rollers are in contact with the wall of the steel pipe to ensure that the supporting height matches the axial height of the steel pipe. The stability of the steel pipe processing process is realized through the support and constraint of the first rollers on the bottom of the steel pipe and the support and constraint of the second rollers on the side of the steel pipe, thereby ensuring the quality of the press groove.
