Description

Technical Field

[0001] This utility model relates to the field of steel pipe pile welding technology, and in particular to a flipping structure for segmented splicing welding of steel pipe piles. Background Technology

[0002] Steel pipe piles are construction materials composed of steel pipes, tongue and groove joints, and tongue and groove pins. After being processed into sections, steel pipe piles are assembled by welding according to the required length. However, when welding steel pipe piles with large diameters and weights, workers cannot weld from one side due to the large diameter. Usually, it is necessary to use a hoist or manually move the steel pipe to rotate it before continuing welding. This method is relatively time-consuming, labor-intensive, and too expensive. Some have proposed using a simple support base and pulley mechanism to rotate the steel pipe pile, saving manual handling. However, large-diameter steel pipes are heavy, and without any protective measures, it is very easy for the steel pipe pile to fall when rotated. Therefore, a flipping structure for segmented splicing and welding of steel pipe piles is designed to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology, and to propose a flipping structure for segmented splicing and welding of steel pipe piles.

[0004] The technical problem to be solved by this utility model is to provide a flipping structure for segmented splicing and welding of steel pipe piles to solve the problems of existing flipping structures for segmented splicing and welding of steel pipe piles.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A flipping structure for segmented splicing and welding of steel pipe piles includes a support base, a fixing plate, and a positioning ring. Multiple fixing plates are fixedly installed on one side of the outer surface of the support base, and positioning rings are fixedly installed on the outer ends of the fixing plates. The steel pipe piles to be welded are embedded in the positioning rings. A motor is installed on the other side of the support base through a drive assembly, and a clamping assembly for clamping and fixing the steel pipe piles is installed at the output end of the motor. The positioning ring includes a rotating ring and a first hydraulic rod. The rotating ring rotates inside the positioning ring. A plurality of first hydraulic rods are fixedly arranged on the inner surface of the rotating ring. A clamp is fixedly installed at the output end of the first hydraulic rod.

[0006] Preferably, the inner side of the positioning ring is provided with an annular groove that matches the rotating ring. The rotating ring is embedded in and rotatably disposed in the annular groove, which facilitates the rotation of the rotating ring along the annular groove and ensures the stability of the rotating ring's rotation within the positioning ring.

[0007] Preferably, the number of the first hydraulic rods is not less than two, and the angle between two adjacent first hydraulic rods is the same, which facilitates the clamping plates on the multiple first hydraulic rods to clamp and fix the steel pipe pile.

[0008] Preferably, the clamping plate is arc-shaped, and the diameter of the clamping plate is equal to the outer diameter of the steel pipe pile, thereby increasing the contact area between the clamping plate and the steel pipe pile, thus increasing the friction force of the clamping plate after clamping the steel pipe pile and ensuring the stability of the steel pipe pile.

[0009] Preferably, the drive assembly includes a groove formed on the support base and a forward and reverse motor fixed to the left end of the support base. A lead screw is installed at the output end of the forward and reverse motor, and a mounting plate is threaded onto the lead screw. The motor is mounted on the mounting plate.

[0010] Preferably, the lead screw extends into the slide groove, and the right end of the lead screw is rotatably mounted on the right end of the slide groove via a bearing. The height of the mounting plate is the same as the width of the slide groove, and the inner end of the mounting plate extends into and slides within the slide groove, ensuring the stability of the mounting plate sliding within the slide groove.

[0011] Preferably, the clamping assembly includes a rotating shaft at the output end of a motor, a through slot is provided in the center of the rotating shaft, a second hydraulic rod is fixedly installed at the left end of the through slot, a slider is installed at the output end of the second hydraulic rod, a first connecting rod is rotatably arranged on both the inner and outer sides of the right end of the slider via a pin, an inverted concave frame is fixedly installed at the right end of the through slot, a second connecting rod is rotatably arranged on both the inner and outer sides of the inverted concave frame via a pin, and a clamping block is rotatably arranged between the first connecting rod and the second connecting rod on both the inner and outer sides via a pin.

[0012] Preferably, the axis of the rotating shaft is on the same straight line as the axis of the positioning ring and the steel pipe pile, so as to ensure that the rotating shaft positions the steel pipe pile in the positioning ring.

[0013] Preferably, when the second hydraulic rod is retracted to its minimum length, the two clamping blocks are fully embedded in the through groove. When the second hydraulic rod is extended to its maximum length, both clamping blocks extend out of the through groove, making it convenient for the clamping blocks to adhere to the inner surface of the steel pipe pile. The friction between the clamping blocks and the steel pipe pile is used to achieve the effect of positioning the steel pipe pile.

[0014] Preferably, the side of the clamping block facing out of the through groove is provided with a frosted rubber layer to increase the friction between the clamping block and the steel pipe pile.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects: In the above scheme, by setting positioning rings, when the steel pipe piles need to be welded in sections, the two steel pipe piles to be welded are first inserted into the two positioning rings in the center and right side of the support seat, respectively, so that the welding joint of the two steel pipe piles is between the two positioning rings in the center and right side of the support seat. Then, the first hydraulic rod in the positioning ring extends to drive the clamping plate to move towards the steel pipe pile, so that the clamping plate cooperates to clamp and fix the steel pipe pile, ensuring that the welding joint of the two steel pipe piles is aligned, which facilitates the welding of the steel pipe piles.

[0016] In the above scheme, by setting up a motor and a clamping assembly, when the welding surfaces of the two steel pipe piles facing the support seat cannot be welded after welding the outer surfaces of the two steel pipe piles, the drive assembly drives the motor to move to the right, so that the rotating shaft extends into the central through hole of the left steel pipe pile. The second hydraulic rod extends and drives the two first and second connecting rods to rotate. The first and second connecting rods drive the clamping block to extend out of the through groove and stick to the inner surface of the steel pipe pile, thereby achieving the effect of clamping the steel pipe pile. It is applicable to clamping steel pipe piles with different inner diameters. Then, the motor is turned on, and the motor drives the rotating shaft and the steel pipe pile to rotate slowly, so that the welding surface facing the support seat rotates to the surface away from the support seat, which facilitates the circumferential welding of the two steel pipe piles.

[0017] In the above scheme, a drive component is provided, and a forward and reverse motor drives the lead screw to rotate. The lead screw drives the mounting plate to slide left and right along the slide groove, thereby achieving the effect of moving the mounting plate and the motor mounted on the mounting plate left and right. This facilitates the left and right movement of the clamping component driven by the motor, making it convenient to weld steel pipe piles of different lengths. It also ensures that the welded part of the steel pipe pile is located between the center of the support base and the two positioning rings on the right side. Attached Figure Description

[0024] like Figure 1 and Figure 2 As shown, an embodiment of this utility model provides a flipping structure for segmented splicing and welding of steel pipe piles 4, including a support base 1, a fixing plate 2, and a positioning ring 3. Multiple fixing plates 2 are fixedly installed on one side of the outer surface of the support base 1, and positioning rings 3 are fixedly installed on the outer ends of the fixing plates 2. The steel pipe piles 4 to be welded are embedded in the positioning rings 3. A motor 6 is installed on the other side of the support base 1 through a drive assembly, and a clamping assembly for clamping and fixing the steel pipe piles 4 is installed at the output end of the motor 6. The positioning ring 3 includes a rotating ring 301 and a first hydraulic rod 302. The rotating ring 301 rotates inside the positioning ring 3. Multiple first hydraulic rods 302 are fixedly arranged on the inner surface of the rotating ring 301. A clamping plate 303 is fixedly installed at the output end of the first hydraulic rod 302.

[0025] In this embodiment, the inner side of the positioning ring 3 is provided with an annular groove that matches the rotating ring 301. The rotating ring 301 is embedded in and rotated in the annular groove, which facilitates the rotation of the rotating ring 301 along the annular groove and ensures the stability of the rotating ring 301 within the positioning ring 3.

[0026] In this embodiment, the number of first hydraulic rods 302 is not less than two, and the angle between two adjacent first hydraulic rods 302 is the same, which facilitates the clamping plates 303 on the first hydraulic rods 302 to clamp and fix the steel pipe piles 4.

[0027] In this embodiment, the clamping plate 303 is arc-shaped, and the diameter of the clamping plate 303 is equal to the outer diameter of the steel pipe pile 4, which increases the contact area between the clamping plate 303 and the steel pipe pile 4 and increases the friction after clamping.

[0028] With the positioning rings 3 in place, when the steel pipe piles 4 need to be welded in sections, the two steel pipe piles 4 to be welded are first inserted into the two positioning rings 3 in the center and right side of the support base 1, respectively, so that the welding point of the two steel pipe piles 4 is between the two positioning rings 3 in the center and right side of the support base 1. Then, the first hydraulic rod 302 in the positioning ring 3 extends and drives the clamping plate 303 to move towards the steel pipe pile 4, so that the clamping plate 303 cooperates to clamp and fix the steel pipe pile 4, ensuring that the welding point of the two steel pipe piles 4 is aligned, which facilitates the welding of the steel pipe piles 4.

[0029] like Figure 3 As shown, in this embodiment, the drive assembly includes a slide groove 101 formed on the support base 1 and a forward and reverse motor 5 fixed to the left end of the support base 1. A lead screw 501 is installed at the output end of the forward and reverse motor 5, and a mounting plate 502 is threaded onto the lead screw 501. The motor 6 is mounted on the mounting plate 502.

[0030] In this embodiment, the lead screw 501 extends into the slide groove 101, and the right end of the lead screw 501 is rotatably mounted on the right end of the slide groove 101 via a bearing. The height of the mounting plate 502 is the same as the width of the slide groove 101, and the inner end of the mounting plate 502 extends into and slides within the slide groove 101 to ensure the stability of the mounting plate 502 sliding within the slide groove 101.

[0031] With the drive assembly, the forward and reverse motor 5 drives the lead screw 501 to rotate, and the lead screw 501 drives the mounting plate 502 to slide left and right along the slide groove 101, thereby achieving the effect of moving the mounting plate 502 and the motor 6 mounted on the mounting plate 502 left and right. This facilitates the left and right movement of the clamping assembly driven by the motor 6, making it convenient to weld steel pipe piles 4 of different lengths, and ensuring that the welded part of the steel pipe pile 4 is located between the center of the support base 1 and the two positioning rings 3 on the right side.

[0032] like Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the clamping assembly includes a rotating shaft 7 at the output end of the motor 6. A through groove 701 is provided in the center of the rotating shaft 7. A second hydraulic rod 702 is fixedly installed at the left end of the through groove 701. A slider 703 is installed at the output end of the second hydraulic rod 702. A first connecting rod 704 is rotatably provided on both the inner and outer sides of the right end of the slider 703 via a pin. An inverted concave frame 705 is fixedly provided at the right end of the through groove 701. A second connecting rod 706 is rotatably provided on both the inner and outer sides of the inverted concave frame 705 via a pin. A clamping block 707 is rotatably provided between the first connecting rod 704 and the second connecting rod 706 on both the inner and outer sides via a pin.

[0033] In this embodiment, the axis of the rotating shaft 7 is on the same straight line as the axis of the positioning ring 3 and the steel pipe pile 4, ensuring that the rotating shaft 7 positions the steel pipe pile 4 within the positioning ring 3.

[0034] In this embodiment, when the second hydraulic rod 702 is retracted to its minimum length, the two clamping blocks 707 are fully embedded in the through groove 701. When the second hydraulic rod 702 is extended to its maximum length, the two clamping blocks 707 extend out of the through groove 701, making it convenient for the clamping blocks 707 to adhere to the inner surface of the steel pipe pile 4. The friction between the clamping blocks 707 and the steel pipe pile 4 is used to achieve the effect of positioning the steel pipe pile 4.

[0035] In this embodiment, the side of the clamping block 707 facing outward from the through groove 701 is provided with a frosted rubber layer to increase the friction between the clamping block 707 and the steel pipe pile 4.

[0036] By incorporating a motor 6 and a clamping assembly, when the outer surfaces of two steel pipe piles 4 are welded and the welding surfaces of the two steel pipe piles 4 facing the support seat 1 cannot be welded, the motor 6 is driven to the right by the drive assembly, causing the rotating shaft 7 to extend into the central through hole of the left steel pipe pile 4. The second hydraulic rod 702 extends, causing the two first connecting rods 704 and the second connecting rod 706 to rotate. The first connecting rods 704 and the second connecting rod 706 cause the clamping block 707 to extend out of the through groove 701 and adhere to the inner surface of the steel pipe pile 4, thereby achieving the effect of clamping the steel pipe pile 4. This method is applicable to clamping steel pipe piles 4 with different inner diameters. Then, the motor 6 is turned on, and the motor 6 drives the rotating shaft 7 and the steel pipe pile 4 to rotate slowly, causing the welding surfaces facing the support seat 1 to rotate to the surface away from the support seat 1, which facilitates the circumferential welding of the two steel pipe piles 4.
