Description

Technical Field

[0001] The present invention relates to the technical field of pipe pile grinding, and in particular to a convenient steel pipe pile weld grinding device. Background Art

[0002] Offshore wind power has developed rapidly in recent years. Many offshore wind power equipment cannot do without the use of steel pipe piles. Before the steel pipe piles are put into use, the welds of the steel pipe piles (or pollutants such as oil and scale on their inner and outer surfaces) are polished. However, existing weld grinding equipment is mostly aimed at external welds, and the grinding of internal welds often requires manual grinding. Since it requires reaching into the interior of the steel pipe pile, the vibration during grinding often makes the grinding unstable and the grinding effect poor. Summary of the Invention

[0003] The purpose of the present invention is to provide a convenient steel pipe pile weld grinding device, which can facilitate the grinding inside the steel pipe pile, extend into the interior of the steel pipe pile, and provide support at the end, so that the grinding is more stable, and the grinding movement restriction is small and the reliability is high.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions: A convenient steel pipe pile weld grinding device includes a transverse track beam, a vertical moving vehicle, and a pipe pile moving frame. The transverse track beam is equipped with a grinding assembly that moves along the transverse track beam. The vertical moving vehicle moves in a direction perpendicular to the transverse track beam, approaching or moving away from the outer end of the transverse track beam. The vertical moving vehicle is slidingly connected to a mobile support frame, which is slidably connected to or leaves the outer end of the transverse track beam. The pipe pile moving frame is provided with a steel pipe pile to be polished, and drives it to move axially, so that the transverse track beam and the polishing assembly enter the inner side of the steel pipe pile for polishing.

[0005] Furthermore, the mobile support frame also includes a track shaft connected to the side away from the transverse track beam, and a follower support frame is connected to the track shaft. The follower support frame is sleeved on the track shaft or the end of the transverse track beam, and the outer periphery of the follower support frame is also connected to a number of telescopic parts for pressing against the inner periphery of the steel pipe pile.

[0006] Furthermore, the outer ends of the track shaft and the transverse track beam are provided with positioning holes, and the follower support frame is connected with a telescopic positioning block adapted to the positioning hole.

[0007] Furthermore, the vertical moving vehicle is connected to a positioning drive component, which drives the moving support frame to move in a direction parallel to the transverse track beam.

[0008] Furthermore, a positioning opening is provided on a side of the movable support frame close to the transverse track beam, and the positioning opening is for inserting the transverse track beam.

[0009] Furthermore, the transverse track beam is installed on a fixed rotating frame, which drives the transverse track beam to rotate around a horizontal axis. The movable support frame includes a rotating positioning block, which rotates around the horizontal axis and is connected to the movable support frame. The positioning port is opened in the rotating positioning block.

[0010] Furthermore, the grinding assembly includes a main grinding assembly, which includes a radial feed member and a grinding member. The radial feed member drives the grinding member to approach or move away from the inner wall of the steel pipe pile. The grinding assembly moves along the transverse track beam to grind the inner longitudinal seam.

[0011] Furthermore, the main grinding assembly also includes a motor turntable, and the radial feed part and the grinding part are integrally connected to the motor turntable, driving the radial feed part and the grinding part to rotate around the diameter of the steel pipe pile. The grinding part moves along the transverse track beam and grinds the inner longitudinal seam forward along it, or rotates itself 90 degrees, rotates around the horizontal axis and grinds the inner annular seam along its circumference.

[0012] Furthermore, the grinding assembly further includes one or more auxiliary grinding assemblies, and the auxiliary grinding assembly includes a radial feeding member and a grinding member.

[0013] Furthermore, a lifting abutment device is provided above the transverse track beam, and the lifting abutment device abuts against the upper end of the steel pipe pile.

[0014] In summary, the present invention has the following beneficial effects: The steel pipe pile to be ground is placed on the pile moving frame, which drives it to move axially, allowing the grinding assembly to enter the inner side of the steel pipe pile for grinding. The vertical moving vehicle approaches the transverse track beam and is positioned and connected to the outer end of the transverse track beam through the mobile support frame. The grinding assembly then moves along the transverse track beam to achieve full-section grinding of the steel pipe pile, improving the degree of automation of grinding the weld seams inside the steel pipe pile. In response to the situation where the length of the steel pipe pile is longer than the transverse track beam, a follow-up support frame is also set up. The follow-up support frame moves from the mobile support frame to the steel pipe pile, supports and positions it, and then positions it on the transverse track beam. After the support is released, it moves into the steel pipe pile and resumes support to facilitate the grinding of that end. This allows the long steel pipe pile to be ground at the corresponding end twice, thereby improving the adaptability to the size of the steel pipe pile. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. This embodiment does not constitute a limitation of the present invention. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0018] A convenient steel pipe pile weld grinding equipment, such as Figure 1 As shown, it includes a transverse track beam 1, a vertical moving vehicle 2 and a pipe pile moving frame 3. A grinding assembly that moves along the transverse track beam 1 is installed on the transverse track beam 1. The transverse track beam 1 can be set as a linear module, or it can be driven to move linearly by a screw nut, rack and pinion, etc. The vertical moving vehicle 2 moves in a direction perpendicular to the transverse track beam 1, approaching or moving away from the outer end of the transverse track beam. A mobile support frame 21 is slidably connected to the vertical moving vehicle 2. The sliding direction of the mobile support frame 21 is parallel to the transverse track beam 1. By slidably connecting or leaving the outer end of the transverse track beam 1, support is provided at the outer end of the transverse track beam 1 to improve the stability of the grinding and movement of the grinding assembly. The steel pipe piles to be polished are placed on the pipe pile moving frame 3, which drives the steel pipe piles to move axially, so that the transverse track beam 1 and the polishing assembly enter the inner side of the steel pipe piles for polishing.

[0019] like Figure 1 and Figure 2As shown, in order to realize the sliding of the mobile support frame 21, the vertical moving vehicle 2 is connected with a positioning drive member 22 and a parallel track. The positioning drive member 22 drives the mobile support frame 21 to move in a direction parallel to the transverse track beam 1, and the parallel track guides its sliding. In this embodiment, the positioning drive member 22 is a linear module, which can also be replaced by a linear drive component such as a linear motor.

[0020] like Figure 2 As shown, a positioning opening 212 is provided on one side of the mobile support frame 21 close to the transverse track beam 1, and the positioning opening 212 is for the transverse track beam 1 to be inserted. Rolling wheels can be connected to the upper and lower sides of the positioning opening 212 to facilitate guided insertion; a guide block can be fixedly connected to the outer end of the transverse track beam 1, and the cross-section of the guide block gradually becomes smaller toward the outer end to realize the connection between the mobile support frame 21 and the transverse track beam 1.

[0021] like Figure 1 and Figure 2 As shown, in order to realize the rotation of the grinding assembly to adjust the grinding position of the inner longitudinal seam or to grind the inner circumferential seam, the transverse track beam 1 is installed on the fixed rotating frame 11. The fixed rotating frame 11 is driven to rotate by a motor and gears and other structures. Its rotating shaft is horizontal, driving the transverse track beam 1 to rotate around the horizontal axis; Correspondingly, the mobile support frame 21 includes a rotating positioning block 211 close to one side of the transverse track beam 1. The rotating positioning block 211 is connected to the mobile support frame 21 through a bearing and rotates around a horizontal axis. A positioning port 212 is provided in the rotating positioning block 211 for the mobile track beam to be inserted and drive the rotating positioning block 211 to rotate together. The rotating positioning block 211 can be set with a certain rotation damping so that it does not rotate autonomously under normal conditions. The rotating positioning block 211 can also be actively driven to rotate by a driving structure such as a motor.

[0022] like Figure 3 As shown, in order to adapt to the grinding of steel pipe piles of different specifications, a hydraulic or electric control lifting platform 31 is connected to the pipe pile moving frame 3, and a number of V-shaped frames are fixed above the lifting platform 31. The steel pipe piles are placed on the V-shaped frames. The lifting and lowering of the lifting platform 31 controls the axis of the steel pipe piles of different sizes to be collinear with the axis of the transverse track beam 1. They can also be directly transported by the pipe pile moving frames 3 of different heights to ensure that the center height of the steel pipe piles is consistent; In some embodiments, a distance measuring device can be fixed on the transverse track beam 1 to measure the height of the highest point and the lowest end of the inner wall of the steel pipe pile, or the height to which the lifting platform 31 needs to be lifted can be measured based on one of its parameters and the size of the steel pipe pile, so that the steel pipe pile and the transverse track beam 1 are centered or reach a position that is convenient for processing. The height can also be adjusted in advance by manual measurement.

[0023] like Figure 3As shown, the grinding assembly includes a main grinding assembly 4, which includes a motor turntable 43, a radial feed member 41 and a grinding member 42. The radial feed member 41 and the grinding member 42 are integrally connected to the motor turntable 43, driving the radial feed member 41 and the grinding member 42 to rotate around the diameter of the steel pipe pile. The grinding member 42 moves along the transverse track beam 1 and grinds the inner longitudinal seam forward along it, or after rotating 90 degrees, drives the grinding assembly as a whole to rotate around the horizontal axis through the fixed rotating frame 11, and grinds the inner annular seam along the circumference of the steel pipe pile. The grinding can be performed by pre-manual setting or visual sensing and other identification methods to grind the weld position; Among them, the motor turntable 43 is a turntable base driven by a motor and gears, or other existing self-rotating structures. The radial feed member 41 is an electric telescopic cylinder. The grinding member 42 is connected to the output end of the radial feed member 41. The grinding member 42 includes a motor and a grinding wheel driven by the motor. The radial feed member 41 drives the grinding member 42 to approach or move away from the inner wall of the steel pipe pile. Finally, the grinding assembly moves along the transverse track beam 1 or rotates circumferentially to grind the inner longitudinal seam or the inner circumferential seam. In this embodiment, the grinding assembly further includes one or more auxiliary grinding assemblies 5, which only include radial feed members 41 and grinding members 42, and the grinding direction is tangential, and is only used for grinding the inner annular seam to speed up the grinding efficiency of the inner annular seam; the main grinding assembly 4 and the auxiliary grinding assembly 5 can be connected to the same moving block to move along the transverse track beam 1, In some embodiments, the transverse track beam 1 includes a lead screw and a guide rod, and is connected to the movable plate to guide and drive its sliding. The upper and lower side surfaces of the movable plate are connected to corresponding movable blocks, so that the two movable blocks move along the slide rails on the upper and lower side surfaces of the transverse track beam 1. Under the drive of the lead screw, the upper and lower movable blocks achieve synchronous movement and are connected to the corresponding main grinding assembly 4 and auxiliary grinding assembly 5 to achieve their synchronous movement. In some other embodiments, the main grinding component 4 and the auxiliary grinding component 5 are driven to move by two sets of linear modules, so that the main grinding component 4 grinds the inner longitudinal seam and the inner annular seam, and the auxiliary grinding component 5 only grinds the inner annular seam, so that the inner annular seam can be synchronously ground at different positions or at different angles at the same position, thereby improving the annular seam grinding efficiency.

[0024] like Figure 3 As shown, in order to improve the stability during grinding and further reduce vibration, a lifting abutment device 6 is further provided above the transverse track beam 1. The lifting abutment device 6 abuts against the upper side of the steel pipe pile. The lifting abutment device 6 includes an electric cylinder and an abutment wheel connected to the output end of the electric cylinder. The abutment wheel can be single or two symmetrical wheels, and can also be replaced by structures such as a V-frame or a symmetrical roller.

[0025] like Figure 2 and Figure 4As shown, in order to improve the versatility of long steel pipe piles, the mobile support frame 21 also includes a track shaft 213 connected to the side away from the transverse track beam 1, and a follower support frame 7 is connected to the track shaft 213 (the track shaft 213 can also be connected to a distance measuring device, etc.), and one side of the follower support frame 7 is sleeved on the track shaft 213 or the end of the transverse track beam 1 (the follower support frame 7 is connected to a turntable on the side close to the transverse track beam 1, and an opening of the same size as the positioning opening 212 is provided in the turntable to facilitate insertion and rotation), and the outer periphery of the other side of the follower support frame 7 is further connected to a plurality of telescopic members for pressing against the inner periphery of the steel pipe pile, and the telescopic members are telescopic blocks driven to move by the telescopic pressing cylinder 71; Among them, in order to position the follower support frame 7 on the track shaft 213 or the end of the transverse track beam 1, the track shaft 213 and the outer end of the transverse track beam 1 are provided with radial positioning holes, and a telescopic positioning block 72 adapted to the positioning hole is connected to the follower support frame 7. The telescopic positioning block 72 is driven to retract by an electric cylinder. In an embodiment in which part of the transverse track beam 1 needs to be rotated, the electric cylinder and the telescopic positioning block 72 can be fixed in the turntable of the follower support frame 7, or fixed in the non-turntable position outside the follower support frame 7, and the track shaft 213 or the transverse track beam 1 is only inserted for positioning during non-rotating operation.

[0026] Working principle: For short steel pipe piles (shorter than transverse track beam 1), like Figure 5 As shown, the steel pipe pile to be polished is placed on the pipe pile moving frame 3, and it is driven to move axially, so that the transverse track beam 1 and the polishing assembly enter the inner side of the steel pipe pile for polishing. The vertical moving vehicle 2 approaches the transverse track beam 1 and is positioned and plugged into the outer end of the transverse track beam 1 through the movement of the mobile support frame 21; Then, the grinding assembly moves along the transverse track beam 1 to achieve full-section grinding of the axial weld inside the steel pipe pile. At the same time, when it moves to the inner circumferential seam position, the fixed rotating frame 11 drives the transverse track beam 1 to rotate around the horizontal axis to achieve grinding of the circumferential weld inside the steel pipe pile. After completion, the vertical moving vehicle 2 and the mobile support frame 21 are reset. For long steel pipe piles (longer than the transverse track beam 1), grind the left and right ends separately. like Figure 6 and Figure 7 As shown, the vertical moving vehicle 2 first moves to the outer end of the horizontal track beam 1, and the steel pipe pile to be polished is placed on the pipe pile moving frame 3, and drives its corresponding end to move forward, so that the follower support frame 7 can enter the steel pipe pile; The follower support frame 7 is pressed against the inner periphery of the steel pipe pile by extending the telescopic pressing cylinder 71, and the insertion and positioning of the telescopic positioning block 72 and the track shaft 213 are released; The mobile support frame 21 moves, causing the track shaft 213 to leave the follower support frame 7, and the vertical moving vehicle 2 leaves as a whole; then the pipe pile moving frame 3 continues to move forward, causing the transverse track beam 1 to be inserted into the follower support frame 7, and is inserted and positioned with the transverse track beam 1 through the telescopic positioning block 72, and then the follower support frame 7 releases the tight contact with the inner circumference of the steel pipe pile by retracting the telescopic abutting cylinder 71; The pipe pile moving frame 3 continues to move forward until the end of the steel pipe pile reaches the inner end of the transverse track beam 1. The follower support frame 7 extends the telescopic abutment cylinder 71 and abuts against the inner periphery of the steel pipe pile. After maintaining or releasing the insertion and positioning of the telescopic positioning block 72 and the track shaft 213 as needed, the support preparation work is completed and it is ready for grinding. Finally, the inner weld of the left or right half of the steel pipe pile is ground by the grinding assembly; the follower support frame 7 is reset in reverse according to the above steps, waiting for the next steel pipe pile reversal or the next steel pipe pile grinding work.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions should also be deemed to fall within the protection scope of the technical solution of the present invention.
