Description

Technical Field

[0001] This invention relates to the field of pipe pile grinding technology, and in particular to a high-efficiency grinding equipment for the external weld seams of steel pipe piles. Background Technology

[0002] In recent years, offshore wind power has developed rapidly, and many offshore wind power equipment rely on the use of steel pipe piles. Before steel pipe piles are put into use, the external welds or the outer surface of the steel pipe piles are ground to remove contaminants such as oil and oxide scale. However, existing weld grinding equipment generally requires driving the steel pipe pile to rotate in order to facilitate the grinding of its outer circumferential seam. However, for large steel pipe piles, the rotation drive consumes a lot of energy and the grinding efficiency is low. In addition, the processing errors of the steel pipe pile itself, the unground longitudinal seam or dirt on the outside can cause the steel pipe pile to vibrate and become eccentric during rotation, thus affecting the grinding effect. Summary of the Invention

[0003] The purpose of this invention is to provide a high-efficiency steel pipe pile external weld grinding equipment, which can improve the grinding efficiency of steel pipe pile external welds and is equipped with an autonomous rotating grinding tunnel, so that the grinding components can rotate autonomously without the need for the steel pipe pile to drive the rotation, thereby improving the grinding effect.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0005] A high-efficiency steel pipe pile external weld grinding equipment includes a trolley moving tunnel and several moving trolleys. A self-rotating grinding tunnel is located directly above the trolley moving tunnel. The trolley moving tunnel has an inlet and an outlet at each end, located on the outer sides of the corresponding ends of the self-rotating grinding tunnel. The moving trolleys carry the steel pipe piles to be ground. The moving trolleys move, transporting the steel pipe piles into the self-rotating grinding tunnel. The self-rotating grinding tunnel includes a circumferentially rotating base, with several grinding components for grinding the steel pipe piles distributed around its inner circumference. The moving trolleys sequentially enter the trolley moving tunnel downwards from the inlet and finally exit the trolley moving tunnel upwards from the outlet.

[0006] Furthermore, the entrance to the trolley moving tunnel includes a descending ramp, and the trolley enters the trolley moving tunnel along the descending ramp.

[0007] Furthermore, the exit of the trolley moving tunnel includes a lifting platform and a power component that drives the lifting platform to rise and fall. The trolley enters the lifting platform along the trolley moving tunnel, and the power component drives the lifting platform to rise, allowing the trolley to leave the trolley moving tunnel and continue forward.

[0008] Furthermore, the power component includes several vertical hydraulic cylinders, the lower ends of which are connected to the lifting platform to drive the lifting platform to rise and fall.

[0009] Furthermore, the grinding assembly includes a fixed platform, on which a first radial feed member is connected. The first radial feed member is connected to the circumferential grinding member, and the first radial feed member drives the circumferential grinding member to approach or move away from the outer wall of the steel pipe pile to grind the outer circumferential joint of the steel pipe pile.

[0010] Furthermore, the grinding assembly includes a rotating table and a switching drive unit that drives the rotating table to rotate. A second radial feed unit is connected to the rotating table and is connected to the longitudinal seam grinding unit. The second radial feed unit drives the longitudinal seam grinding unit to approach or move away from the outer wall of the steel pipe pile, and grinds the outer circumferential seam or outer longitudinal seam of the steel pipe pile according to the rotation angle of the rotating table.

[0011] Furthermore, the mobile trolley is connected to several abutment rollers, with the center of each roller recessed for placing the steel pipe pile.

[0012] Furthermore, the autonomous rotating grinding tunnel includes fixed brackets at both ends, with steel pipe piles supported on the fixed brackets.

[0013] Furthermore, the autonomous rotating grinding tunnel includes fixed seats at both ends, a rotating seat rotatably connected between the two fixed seats, and an autonomous rotating drive component that drives the rotating seat to rotate is also connected in the fixed seats.

[0014] Furthermore, the autonomous rotation drive includes a tunnel rotation drive motor, the output end of which is connected to a drive gear, and the outer circumference of the rotating seat has a toothed profile, with the drive gear meshing with the toothed profile of the rotating seat.

[0015] In summary, the present invention has the following beneficial effects:

[0016] The mobile trolley carries the steel pipe piles to be ground. The trolley moves, transporting the steel pipe piles into the autonomous rotary grinding tunnel. Simultaneously, the mobile trolley sequentially enters the trolley moving tunnel from the inlet downwards and finally exits from the trolley moving tunnel upwards from the outlet, continuing to transport steel pipe piles. The autonomous rotary grinding tunnel uses grinding components to grind the outer circumferential and outer longitudinal seams of the steel pipe piles, improving the grinding efficiency of the outer weld seams of the steel pipe piles and avoiding the need for driving the steel pipe piles to rotate, thus improving the final grinding effect.

Detailed Implementation

[0023] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. These embodiments do not constitute a limitation of the present invention. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0024] A high-efficiency steel pipe pile external weld grinding equipment, such as Figure 1 As shown, it includes a trolley-moving tunnel 1 and several trolleys 2. A self-rotating grinding tunnel 3 is provided directly above the trolley-moving tunnel 1 (the self-rotating grinding tunnel 3 is installed on the ground, and the trolleys 2 move along the ground or on the track on the ground. The track can extend to the trolley-moving tunnel 1 and other moving paths; the trolley-moving tunnel 1 is reinforced externally to ensure strength). The trolley-moving tunnel 1 has an entrance and an exit at both ends, and the entrance and exit are located on the outer side of the corresponding ends of the self-rotating grinding tunnel 3, so that the trolleys 2 can drive in or out.

[0025] The mobile trolley 2 carries the steel pipe pile to be ground. The mobile trolley 2 moves linearly under the drive of the internal drive device or the traction of the head tractor, and transports the steel pipe pile into the autonomous rotary grinding tunnel 3. The autonomous rotary grinding tunnel 3 includes a circumferentially rotating seat 31. Several grinding components for grinding the steel pipe pile are distributed on the inner circumference of the rotating seat 31. The steel pipe pile is transported into the center of each grinding component, so that the grinding of the outer ring seam is completed without the steel pipe pile rotating.

[0026] like Figure 1 and Figure 2As shown, the mobile trolley 2 is connected to several abutment rollers 21. The abutment rollers 21 are concave in the middle for placing steel pipe piles. They can be concave surfaces obtained by V-shaped or arc-shaped rotation. In some embodiments, only one abutment roller 21 is connected to the mobile trolley 2 to facilitate downward entry into the trolley moving tunnel 1 and reduce interference with the steel pipe piles.

[0027] The mobile trolley 2 enters the mobile tunnel 1 from the inlet downwards and finally exits the mobile tunnel 1 from the outlet upwards.

[0028] like Figure 1 As shown, the entrance of the trolley moving tunnel 1 includes a descending ramp 11, which can be transitioned by curves at both ends to improve the smoothness of the moving trolley 2. The moving trolley 2 enters the trolley moving tunnel 1 along the descending ramp 11. In some embodiments, its exit can also be a corresponding ascending ramp, so as to enable the moving trolley 2 to move around the autonomous rotating grinding tunnel 3.

[0029] In order to avoid the upper steel pipe piles interfering with the uphill movement of the mobile trolley 2, in this embodiment, the exit of the mobile tunnel 1 includes a lifting platform 12 and a power component that drives the lifting platform 12 to rise and fall. The mobile trolley 2 enters the lifting platform 12 along the mobile tunnel 1, and the power component drives the lifting platform 12 to rise, so that the mobile trolley 2 can leave the mobile tunnel 1 and continue to move forward.

[0030] The power unit includes a fixed frame and several vertical hydraulic cylinders 13 that are hinged or fixed in the fixed frame. The lifting platform 12 includes a base plate and an upper frame. A vertical rail can be connected in the fixed frame, and a matching slider can be connected to the outside of the lifting platform 12 to guide the lifting of the lifting platform 12. The lower end of the vertical hydraulic cylinders 13 is hinged or fixedly connected to the upper frame of the lifting platform 12 to drive the lifting platform 12 to lift. It can also be replaced by an existing traction device or a scissor lift or other lifting device to achieve lifting.

[0031] like Figure 1 and Figure 3 As shown, the autonomous rotating grinding tunnel 3 includes fixed seats 32 at both ends, and a rotating seat 31 is rotatably connected between the two fixed seats 32 through bearings at both ends (the inner circumference of the rotating seat 31 has several chip discharge ports to facilitate chip discharge after grinding, which can also be replaced by a collection port in the fixed seat 32 to suck the discharged chips into the collection port). An autonomous rotating drive component that drives the rotating seat 31 to rotate is fixedly connected to the outside of the fixed seat 32. In this embodiment, the autonomous rotating drive component includes a tunnel rotating drive motor 33, the output end of which is connected to components such as drive gears. Corresponding teeth are opened on the outer circumference of the rotating seat 31. The tunnel rotating drive motor 33 drives the rotating seat 31 to rotate through the meshing of the drive gear with the teeth of the rotating seat 31. The tunnel rotating drive motor 33 can be set as two symmetrical ones or more, and synchronous drive can be achieved at both ends of the rotating seat 31 to improve the stability of the rotating seat 31.

[0032] In some embodiments, the self-rotating grinding tunnel 3 also includes fixed brackets 6 at both ends, with fixed seat 32 and rotating seat 31 located between the two fixed brackets 6, and the steel pipe pile supported on the fixed brackets 6; in this embodiment, the fixed bracket 6 includes two sets of rollers, the same as the abutment roller 21, which abut against the upper and lower sides of the steel pipe pile respectively, thereby improving the stability of the steel pipe pile during transportation within the self-rotating grinding tunnel 3.

[0033] like Figure 3 As shown, the grinding assembly inside the rotating seat 31 includes several fixed platforms 4. The fixed platforms 4 are connected to a first radial feed member 41 (linear module or linear motor or other linear drive). The output end of the first radial feed member 41 is connected to the circumferential grinding member 42 (grinding wheel or other grinding machine). The first radial feed member 41 drives the circumferential grinding member 42 to approach or move away from the outer wall of the steel pipe pile, and grinds the outer circumferential joint of the steel pipe pile in the circumferential direction.

[0034] In some embodiments, the grinding assembly includes a rotating table 5 and a switching drive unit that drives the rotating table 5 to rotate. A fixed table 4 and multiple rotating tables 5 together form the grinding assembly, which are evenly distributed on the inner circumference of the rotating seat 31. The switching drive unit includes a switching motor 53. The output end of the switching motor 53 drives the rotating table 5 to rotate through belt drive or gear drive, etc. The rotating table 5 is rotatably connected to the rotating seat 31 through a rotating shaft. A second radial feed member 51 (linear module or linear motor, etc.) is fixedly connected to the inner side of the rotating table 5. The output end of the second radial feed member 51 is connected to the longitudinal seam grinding member 52 (grinding wheel, etc.). The second radial feed member 51 drives the longitudinal seam grinding member 52 to approach or move away from the outer wall of the steel pipe pile. The outer circumferential seam or outer longitudinal seam of the steel pipe pile is ground along the circumferential or axial direction according to the rotation angle of the rotating table 5. It can automatically identify or monitor the manually identified weld seam for grinding through a visual recognition device, or it can perform grinding work according to the preset angle.

[0035] Working principle:

[0036] like Figure 4 As shown, the steel pipe piles to be ground are supported on multiple mobile trolleys 2. The mobile trolleys 2 move forward and transport the steel pipe piles into the autonomous rotating grinding tunnel 3. At the same time, the mobile trolleys 2 enter the trolley moving tunnel 1 from the inlet along the falling slope 11 under their own weight.

[0037] The steel pipe pile continues to move forward under the action of the rear moving trolley 2, entering the autonomous rotary grinding tunnel 3. At the longitudinal joint position, the tunnel rotation drive motor 33 drives the rotating seat 31 to rotate, and the switching motor 53 drives the longitudinal joint grinding component 52 to rotate, so that the longitudinal joint grinding component 52 is aligned with the longitudinal joint position. The second radial feed component 51 drives the longitudinal joint grinding component 52 to approach the outer wall of the steel pipe pile, and grinds the outer longitudinal joint in conjunction with the forward movement of the steel pipe pile. At the circumferential joint position, the switching motor 53 drives the longitudinal joint grinding component 52 to rotate 90 degrees, so that each circumferential joint grinding component 42 and the longitudinal joint grinding component 52 are aligned with the circumferential joint position. The first radial feed component 41 and the second radial feed component 51 simultaneously drive them to approach the outer wall of the steel pipe pile, and in conjunction with the tunnel rotation drive motor 33 driving the rotating seat 31 to rotate, the outer circumferential joint is ground. The grinding can be automatically controlled by visual sensing or manually controlled by monitoring devices in the autonomous rotary grinding tunnel 3.

[0038] like Figure 5 As shown, during the continuous grinding process, the mobile trolley 2 also moves to the front end of the trolley moving tunnel 1 in sequence and enters the lifting platform 12. The vertical hydraulic cylinder 13 drives the lifting platform 12 to rise, lifting the mobile trolley 2 until it abuts against the bottom of the steel pipe pile. After the mobile trolley 2 is driven forward and leaves with the steel pipe pile, the lifting platform 12 returns to its original position, waiting for the next mobile trolley 2 to enter, until the last mobile trolley 2 leaves with the steel pipe pile, completing the grinding work of the steel pipe pile.

Those skilled in the art can make various modifications or equivalent substitutions to the present invention within the scope of its essence and protection. Such modifications or equivalent substitutions should also be considered to fall within the protection scope of the present invention.
