Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a steel pipe pile docking and positioning device. Background Art

[0002] In the complex and delicate engineering of bridge construction, steel pipe piles, as key construction structures, play a vital role. They not only bear the weight of the bridge but also ensure the stability and safety of the entire structure. Butt welding technology is crucial in the butt-jointing of steel pipe piles, directly impacting the strength of the connection and the overall quality of the bridge.

[0003] Traditional steel pipe pile butt welding processes typically utilize support rollers as a support structure during the welding process. This design ensures the steel pipe pile remains stable on a horizontal surface, facilitating welder operation. Furthermore, a motor is installed on the support rollers, which rotates the steel pipe pile to achieve circular welding at the joint.

[0004] However, weld displacement not only reduces the connection strength between steel pipe piles but also increases safety risks during bridge operation. Existing butt-welded structures suffer from a significant flaw during welding: the lack of necessary positioning structures around the welds. Because steel pipe piles are held in position by supporting rollers during welding, even the slightest movement or deformation around the welds can cause the welds to shift, compromising welding quality and effectiveness. Therefore, it is necessary to develop a butt-weld positioning device for steel pipe piles. Utility Model Content

[0008] Furthermore, positioning holes and positioning rods are provided on the docking plates, and the positioning holes and positioning rods on the docking plates on both sides correspond to each other.

[0009] Furthermore, the side shift seat includes a fixed seat, an adjusting rod and a movable seat.

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0026] Example 1. This embodiment aims to provide a steel pipe pile docking and positioning device, which is mainly used for performing circular welding on steel pipe piles. In view of the current steel pipe pile welding structure, the steel pipe pile is generally rotated, and the welding machine is in a relatively fixed state under working conditions, thereby realizing the circular weld welding of the steel pipe pile. However, during the implementation process, the rotational stability of the steel pipe pile plays a vital role, otherwise it will cause the weld to deform and shift, and the flatness and firmness of the weld will not meet the requirements. Based on this, this embodiment provides a steel pipe pile docking and positioning device.

[0027] like Figure 1 As shown in, a steel pipe pile docking positioning device includes a supporting roller 2, a first positioning assembly 4, a second positioning assembly 5 and a welding assembly 3; the welding assembly 3 includes a bracket 33, a welding machine and a welding head 34, wherein the bracket 33 is fixed with a welding machine, the welding machine is connected to the welding head, the welding head 34 faces the center of the bracket, and forms a welding station; in implementation, the welding assembly 3 is a prior art, which can be an adjustable structure, such as front and rear translation and up and down adjustment, wherein the front and rear translation can be configured with a slide bar, one side of the slide bar 32 is rotated and configured on the bracket 33 to realize the swing function, and the welding seat body 33 is slidably set on the slide bar 32 to realize the sliding of the welding seat body 33, so that the welding seat body moves to the corresponding position, and the up and down adjustment can be a telescopic sleeve rod structure, such as a screw lift, which uses a motor to drive the screw rod to rotate, and is limited by the configured side rod to make the lifting seat move up and down to adjust the welding gap. The prior art can refer to Patent No. 201320322913.6 A utility model patent discloses a welding device for the outer ring weld of a steel pipe pile.

[0028] In the overall layout, the welding assembly 3 is configured in the middle area, the supporting rollers 2 are arranged on the left and right sides of the welding station to form a supporting station, and the first positioning assembly 4 and the second positioning assembly 5 are distributed on the front and back sides of the welding station for positioning at the end of the steel pipe pile; the welding assembly 3 is swung to the left and right sides through the sliding rod structure to open the upper space, which facilitates the loading and unloading of the steel pipe piles.

[0029] In order to ensure the stability of the steel pipe piles, the first positioning assembly 4 and the second positioning assembly 5 both include a positioning frame 41, a docking plate 25, a side shift seat 42, a side shift rail 43, a driving member and a positioning wheel 44; the side shift rail 43 is arranged on the front and rear sides of the welding station, the side shift seat 42 is slidably set on the side shift rail 43, the driving member is connected to the side shift seat 42, and can drive the side shift seat 42 to slide on the side shift rail 43, thereby completing the opening and closing of the first positioning assembly 4 and the second positioning assembly 5.

[0030] During implementation, the driving member is used to translate the side shift seat 42, which can be a telescopic cylinder, an electric push rod, or a screw drive structure; in order to ensure the synchronization of the two sides, a reverse threaded screw can be preferably used, and the reverse threaded screw can be arranged on the side shift seat 42. By utilizing the limit of the side shift seat 42 and the side shift track 43, the reverse threaded screw is driven by a motor, so that the side shift seats 42 on both sides can move inward synchronously.

[0031] The positioning frame 41 is a semi-annular structure fixed to the side shifting seat 42. Docking plates 25 are provided at both ends of the positioning frame 41. At least two sets of positioning wheels 44 are provided and distributed along the circumference of the positioning frame 41. In a specific embodiment, the positioning frame 41 includes a left half-ring and a right half-ring, which are connected by a connecting rod and fixed to the side shifting seat 42. The positioning wheels 44 are arranged along the circumference of the left and right half-rings to respectively position the ends of the steel pipe piles on both sides.

[0032] In order to ensure the positioning effect, this embodiment is provided with positioning holes and positioning rods on the docking plates 25. The positioning holes and positioning rods on the docking plates 25 on both sides correspond to each other, and a mutually interlaced structure is adopted to realize the docking of the left half ring and the right half ring into a ring. The ring structure is large and is concentrically arranged with the steel pipe column.

[0033] The supporting roller 2 includes a supporting roller and a power roller. The power roller and the supporting roller are rotatably arranged on a support. The power roller is connected to a drive motor. The drive motor drives the power roller to rotate. During the rotation, the steel pipe pile is slowly rotated by means of friction, and the welding head is in a relatively fixed state to realize the circular welding of the steel pipe pile. In order to receive impurities generated by welding, a material receiving box can be provided at the bottom of the welding station.

[0034] During implementation, this embodiment incorporates a first positioning assembly 4 and a second positioning assembly 5, creating a clamping, stabilizing structure on either side of the weld. This design effectively limits the movement of the steel pipe piles during welding, thereby ensuring the accuracy and uniformity of the weld. The provision of positioning wheels 44 further enhances the stability around the weld, allowing the steel pipe piles on either side to maintain a stable docking position and centered rotation during the weld formation process, thereby improving the strength and durability of the weld. Through the precise clamping and stabilizing action of the positioning assemblies, this device improves welding efficiency and reduces the rework rate caused by weld displacement, thereby saving time and costs.

[0035] Example 2: This example is basically the same as Example 1, except that Example 1 is mainly applicable to steel pipe piles of fixed sizes, while this example can be applicable to steel pipe pile structures of different sizes.

[0036] In this embodiment, the side shift seat 42 includes a fixed seat 424, an adjusting rod and a movable seat 421. The upper part of the movable seat 421 is fixedly provided with an adjusting rod, and the upper part of the adjusting rod is fixed with a movable seat. The positioning frame 41 is fixed on the fixed seat 424. The adjusting rod includes a sleeve rod, a sleeve and a top screw. The sleeve rod 423 is fixed in the sleeve 422 and locked by the top screw. The sleeve rod 423 and the sleeve 422 are fixedly connected to the fixed seat 424 and the movable seat 421 respectively.

[0037] like Figure 6 As shown in FIG, the positioning wheel 44 is oriented toward a specific center 7, i.e., radially along the large ring, i.e., in the direction of the radial line 9, and is adjustable in length along the radial line 9. This embodiment provides two specific adjustment methods. First, the positioning wheel 44 includes an adjustment seat 442, an adjustment rod 443, and a top wheel 441. The adjustment rod slides within the adjustment seat 442 and can be locked with a top screw. The top wheel is fixed to the end of the adjustment rod. Second, the positioning wheel 44 includes an adjustment rod 444, an adjustment seat 443, an adjustment cap 447, and a limit seat 446. The adjustment rod slides within the adjustment seat, and a limit seat is provided on the adjustment rod. The adjustment cap rotates within the limit seat, and its end is threadedly connected to the outer side of the adjustment seat. Specifically, the connection can be made via a threaded structure 449. As the thread advances, the length is adjusted. For ease of operation, an operating lever 448 is provided on the adjustment cap 447.

[0038] In this embodiment, the height is adjusted by an adjusting rod, that is, the height of the center of the circle is adjusted. During implementation, since the supporting roller 2 is in a fixed state, it basically constitutes an isosceles trapezoidal support structure, and the center of the steel pipe pile is on the center line 8. As the pipe diameter changes, the center of the circle 7 is at different positions on the center line, and the position is adapted by the adjusting rod.

[0039] In order to ensure the clamping effect, the positioning wheel 44 is used for telescopic adjustment to achieve clamping of different outer surfaces, and the clamping wheel in the structure is a rotating structure that can fit and roll with the surface of the steel pipe pile.

[0040] The design of the support rollers 2 and positioning wheels 44 allows the device to accommodate steel pipe piles of varying diameters. The combined effect of the upper opening of the support rollers 2 and the retractable structure of the positioning wheels 44 allows the device to accommodate steel pipe piles of varying sizes to a certain extent, thereby enhancing its versatility and flexibility.

[0041] The above-described embodiments of the present invention do not limit the scope of protection of the present invention. The basic concept of the present invention is to form a clamping and stabilizing structure on both sides of the weld by introducing a first positioning assembly and a second positioning assembly. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
