DETAILED DESCRIPTION

[0032] In order to more clearly illustrate the technical scheme of the present application, the following will briefly introduce the drawings needed to be used in the embodiment description. Obviously, the drawings described in the following description are some embodiments of the present application, and for those skilled in the art, other drawings can also be obtained without creative labor.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0034] Example:

[0035] like Figs. 1-3 As shown, this embodiment provides an auxiliary device for grinding the welded joints of pipe piles, including a guide rail, a rotating seat, a fixed support 6, an adjusting rod assembly, and an angle grinder 12;

[0036] The guide rail component is sleeved on the outer wall surface of the pipe pile welding joint 1 and fixed to the pipe pile welding joint 1. The guide rail component is provided with a guide rail part 17 arranged in the radial direction of the pipe pile welding joint 1.

[0037] The rotating seat includes two semi-annular rotating seat bodies 3. One end of the two semi-annular rotating seat bodies 3 is hinged together, and the other end is provided with a locking device. The two semi-annular rotating seat bodies 3 are connected by the locking device to form an annular rotating seat. The rotating seat is sleeved on the outer wall surface of the guide rail and slides in cooperation with the guide rail.

[0038] The adjusting rod assembly is located on the rotating seat, and one end of the adjusting rod assembly is connected to the angle grinder 12.

[0039] In order to overcome the shortcomings of manually operated angle grinder 12 for grinding pipe pile welded joints 1 mentioned in the background art, the auxiliary device of this embodiment is provided with a guide rail sleeved on the outer wall of the pipe pile welded joint 1 and a rotating seat that slides with the guide rail. This allows the angle grinder 12 to move radially relative to the pipe pile welded joint 1 through the rotating seat, thereby achieving 360° rotation around the axis of the pipe pile welded joint 1 for grinding operations. This ensures grinding stability. The adjustable rod assembly reduces the need for workers to manually support the angle grinder 12, thereby reducing safety hazards and labor intensity.

[0040] The specific structure of the guide rail component in this embodiment is as follows:

[0041] The guide rail component includes two semi-annular clamp guide rail bodies 2. The guide rail part is located on the outer wall surface of the semi-annular clamp guide rail body 2, and the inner wall surface of the semi-annular rotating seat body 3 is provided with a guide groove part 18 that cooperates with the guide rail part.

[0042] Specifically, a number of ball bearings 15 are provided between the guide rail and the guide groove.

[0043] Specifically, the guide rail is provided with a placement groove 16 for placing the ball bearing 15. The opening size of the placement groove 16 is smaller than the diameter of the ball bearing 15. This structure can prevent the ball bearing from falling out of the placement groove 16.

[0044] Specifically, the inner wall surface of the semi-annular clamp rail body 2 is provided with a rubber anti-skid piece.

[0045] Meanwhile, the specific structure of the locking device is as follows:

[0046] One end of the semi-annular rotating seat body 3 is provided with a rotating seat, and the other end of the semi-annular rotating seat body 3 is provided with a rotating shaft 13, which is rotationally matched with the rotating seat to realize hinging. The locking device comprises a connecting seat 4 and a connecting piece. The connecting seat 4 is arranged at the other end of the two semi-annular rotating seat bodies 3, and the connecting piece is connected with the two connecting seats 4 to realize that the two semi-annular rotating seat bodies 3 form a rotating seat.

[0047] Specifically, the connecting seat 4 is provided with a threaded hole, and the connecting piece is a connecting bolt piece, one end of which is provided with a connecting nut piece.

[0048] In the above structure, first, the semi-annular clamp rail body 2 is matched with the semi-annular rotating seat body 3, and then the two semi-annular rotating seat bodies 3 are connected through the locking device, that is, through the locking of the connecting nut piece on the connecting bolt piece. According to the diameter size of the pipe pile welding joint 1, the position of the connecting nut piece on the connecting bolt piece is adjusted to realize the adjustment of the distance between the two connecting seats 4. The semi-annular rotating seat body 3 acts on the semi-annular clamp rail body 2, so that the semi-annular clamp rail body 2 is tightly attached to the outer wall surface of the pipe pile welding joint 1.

[0049] In order to prevent the effect of the acting force between the semi-annular rotating seat body 3 and the semi-annular clamp rail body 2 from causing the sliding effect between the guide rail part and the guide groove part, the structure of the ball piece 15 is arranged to realize the rolling sliding effect between the guide rail part and the guide groove part, so as to ensure the smoothness of the relative sliding between the two.

[0050] Meanwhile, the above rubber anti-skid piece can increase the friction between the semi-annular clamp rail body 2 and the pipe pile welding joint 1, so as to ensure that the semi-annular clamp rail body 2 can be stably fixed to the outer wall surface of the pipe pile welding joint 1.

[0051] The adjusting rod assembly of the embodiment comprises a first adjusting rod 7, a second adjusting rod 9, a first adjusting bolt piece 5, a second adjusting bolt piece 8, a third adjusting bolt piece 14 and a fixed clamp 10.

[0052] The first adjusting bolt piece 5 is arranged at one end of the first adjusting rod 7 and penetrates through the fixed support 6. One end of the first adjusting bolt piece 5 is provided with a first adjusting nut piece.

[0053] The second adjusting bolt piece 8 is arranged at the other end of the first adjusting rod 7 and penetrates through one end of the second adjusting rod 9. One end of the second adjusting bolt piece 8 is provided with a second adjusting nut piece.

[0054] The third adjusting screw member 14 is arranged at the other end of the second adjusting rod 9, and the third adjusting screw member 14 passes through the fixing clamp 10, and one end of the third adjusting screw member 14 is provided with a third adjusting nut member.

[0055] Specifically, the angle grinder 12 is provided with a fastening screw member 11, and the fastening screw member 11 is connected with the fixing clamp 10.

[0056] The adjusting rod assembly can further adjust the position of the angle grinder 12 relative to the fixed support 6 according to the polishing angle, and the adjusting rod assembly cooperates with the structure of the guide rail member to adjust the position of the angle grinder 12 relative to the outer wall surface of the pipe pile welding joint 1, and the annular end surface of the pipe pile welding joint 1 can be uniformly polished.

[0057] In summary, the auxiliary device is suitable for polishing the end surface of the concrete pipe pile joint, and can be quickly fixed on the pipe pile body and uniformly polished.

[0058] The above is only a preferred embodiment of the present application, and does not limit the present application in any form, so any modification, equivalent change and modification of the above embodiment according to the technical essence of the present application, which does not deviate from the technical solution content of the present application, still belongs to the scope of the technical solution of the present application.
