DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0043] Please refer to Figures 1-12 The present application provides a technical solution: Embodiment one

[0044] A kind of offshore wind power steel pipe pile outdoor welding operation equipment, its overall construction is on support frame 1. Support frame 1 is the basic framework of the whole equipment, it is composed of annular plate 101 and support column 102 two parts. The two parts are closely connected, and the other components of the device are provided with support platform, a plurality of key components are arranged on this support frame 1, which are first clamping assembly 2, climbing assembly 3, welding assembly 4, hoisting assembly 5 and second clamping assembly 6 respectively, they each play a unique function and cooperate with each other to realize the welding operation of steel pipe pile.

[0045] First clamping assembly 2:

[0046] AsFigure 5 As shown, the first clamping assembly 2 mainly consists of several clamping links 201, a first clamping plate 202, and a first clamping telescopic cylinder 203. The clamping links 201 are rotatably mounted on the support column 102, and one end of each link is rotatably connected to the first clamping plate 202, allowing their movement to directly affect the position of the first clamping plate 202. Similarly, the first clamping telescopic cylinder 203 is rotatably mounted on the support column 102, with one of the clamping links 201 extending outwards. This extended portion is rotatably connected to the movable end of the first clamping telescopic cylinder 203. This connection method ensures that the telescopic movement of the first clamping telescopic cylinder 203 can be converted into the rotational movement of the clamping links 201.

[0047] When the first clamping assembly 2 is needed to clamp the steel pipe pile, the first clamping telescopic cylinder 203 starts to work. If the first clamping telescopic cylinder 203 retracts, the clamping connecting rod 201 will rotate around the connection point with the support column 102 under the push of the telescopic cylinder. Since the various clamping connecting rods 201 are interconnected, the rotation of this clamping connecting rod 201 will drive the other clamping connecting rods 201 to rotate synchronously, thereby causing the first clamping plate 202 to move towards the side wall of the steel pipe pile. When the extension of the first clamping telescopic cylinder 203 reaches a certain extent, the first clamping plate 202 will fit tightly against the side wall of the steel pipe pile, thereby achieving stable clamping of the steel pipe pile by this device. Conversely, when the welding operation is completed or when it is necessary to release the clamp, the first clamping telescopic cylinder 203 extends, driving the clamping connecting rod 201 to rotate in the opposite direction, and the first clamping plate 202 will gradually disengage from the side wall of the steel pipe pile.

[0048] In this embodiment, there are three sets of first clamping components 2, which are arranged in a circumferentially equidistant array on the support frame 1. This enables the device to have good centering, and the first clamping components 2 enable the device to clamp steel pipe piles of different diameters.

[0049] Climbing Component 3:

[0050] like Figure 6 As shown, the climbing assembly 3 mainly includes several climbing connecting rods 301, climbing telescopic cylinders 302, and climbing drive assembly 303. The climbing connecting rods 301 are rotatably mounted on the support column 102, with one end connected to the climbing drive assembly 303. The climbing telescopic cylinders 302 are also rotatably mounted on the support column 102, and one of the climbing connecting rods 301 extends out and is rotatably connected to the movable end of the climbing telescopic cylinder 302. This connection method allows the extension and retraction of the climbing telescopic cylinder 302 to be converted into the rotational movement of the climbing connecting rods 301, thereby affecting the contact and disengagement state between the climbing drive assembly 303 and the sidewall of the steel pipe pile.

[0051] When the equipment needs to climb upwards along the steel pipe pile, the climbing telescopic cylinder 302 starts to work. When the climbing telescopic cylinder 302 retracts, the climbing connecting rod 301, which is rotatably connected to its movable end, rotates around the connection point with the support column 102. Due to the interrelationship between the various climbing connecting rods 301, this rotation drives the climbing drive assembly 303 to move towards the side wall of the steel pipe pile. When the climbing telescopic cylinder 302 extends to a certain extent, the climbing drive assembly 303 will be in close contact with the side wall of the steel pipe pile. At this time, activating the climbing drive assembly 303 allows it to use the friction between itself and the side wall of the steel pipe pile to drive the entire equipment to move upwards along the axial direction of the steel pipe pile. When the equipment needs to stop climbing or descending, the climbing telescopic cylinder 302 extends, causing the climbing connecting rod 301 to rotate in the opposite direction, disengaging the climbing drive assembly 303 from the side wall of the steel pipe pile.

[0052] In this embodiment, the number of climbing components 3 is also three sets, which are arranged in a circumferentially equidistant array on the support frame 1. The climbing components 3 and the first clamping components 2 are arranged at intervals, and their arrangement principle is the same as that of the first clamping components 2, which will not be described in detail here.

[0053] Welding component 4:

[0054] like Figure 7 As shown, the welding assembly 4 mainly consists of an annular guide rail 401, an annular drive slide 402, and a welding robot 403. The annular guide rail 401 is fixedly mounted on the support frame 1, providing an annular sliding track for the annular drive slide 402. The annular drive slide 402 is slidably mounted on the annular guide rail 401, and the cooperation between the two allows the annular drive slide 402 to slide smoothly on the annular guide rail 401. The welding robot 403 is fixedly mounted on the annular drive slide 402; this fixed connection ensures that the sliding of the annular drive slide 402 directly drives the movement of the welding robot 403. The annular drive slide 402 is equipped with components such as a drive motor, which can drive the welding assembly 4 to move on the annular guide rail 401; these details are not elaborated here.

[0055] During the welding operation, the welding robot 403 is fixed on the annular drive slide 402. When the annular drive slide 402 slides on the annular guide rail 401, the welding robot 403 moves along with it. The annular guide rail 401 is set around the steel pipe pile, so the sliding of the annular drive slide 402 will drive the welding robot 403 to make circular motion around the steel pipe pile. In this way, the welding robot 403 can perform comprehensive welding operations on the circumferential surface of the steel pipe pile, ensuring the integrity and quality of the weld.

[0056] Lifting component 5:

[0057] like Figure 8and Figure 9 As shown in the figure, the hoisting assembly 5 is composed of hoisting support column 501, hoisting beam 502, hoisting trolley 503, hoisting winch 504 and hoisting hook 506. The hoisting support column 501 is fixedly arranged on one side of the support frame 1, which provides support and rotation basis for the hoisting beam 502. The hoisting beam 502 is rotatably arranged on the hoisting support column 501, and the hoisting trolley 503 is slidably arranged on the hoisting beam 502, which can move horizontally on the hoisting beam 502. The hoisting winch 504 is fixedly connected to the hoisting trolley 503, and the hoisting cable 505 is wound around the hoisting winch 504, and the hoisting hook 506 is connected to the end of the hoisting cable 505.

[0058] A plurality of sliding wheels 511 are rotatably arranged on the hoisting trolley 503. These sliding wheels 511 are connected to the hoisting trolley 503 through shafts, so that the sliding wheels 511 can freely rotate around the shafts. They are in contact with the tracks of the hoisting beam 502, providing rolling support for the movement of the hoisting trolley 503 on the hoisting beam 502.

[0059] A first speed reducer 512 is also fixedly arranged on the hoisting trolley 503. The first speed reducer 512 is installed on the hoisting trolley 503, and a first driving motor 513 is fixedly arranged on the first speed reducer 512. The shaft of the first driving motor 513 is fixedly connected to the input end of the first speed reducer 512.

[0060] The output end of the first speed reducer 512 is fixedly connected to one of the sliding wheels 511. This connection allows the power output by the first speed reducer 512 to directly act on this particular sliding wheel 511, driving it to rotate.

[0061] When the hoisting trolley 503 needs to move linearly on the hoisting beam 502, the first driving motor 513 is first started. The first driving motor 513 begins to rotate, and since its shaft is fixedly connected to the input end of the first speed reducer 512, the power generated by the motor rotation will be transmitted to the first speed reducer 512.

[0062] After receiving the power from the first driving motor 513, the first speed reducer 512 adjusts the power, mainly adjusting the rotational speed and torque. According to its own speed reduction ratio, the first speed reducer 512 converts the high-speed low-torque power input by the first driving motor 513 into low-speed high-torque power suitable for the movement of the hoisting trolley 503. Then, the first speed reducer 512 transmits the adjusted power to the sliding wheel 511 fixedly connected to it through its output end.

[0063] On the lifting trolley 503, a second speed reducer 514 is arranged. The second speed reducer 514 is fixed on the lifting trolley 503, and its position and mounting mode ensure stability during work. A second driving motor 515 is arranged on the second speed reducer 514, and the shaft of the second driving motor 515 is fixedly connected with the input end of the second speed reducer 514. This connection mode enables the power generated by the second driving motor 515 to be effectively transmitted to the second speed reducer 514.

[0064] The output end of the second speed reducer 514 is fixedly connected with the lifting hoist 504.

[0065] When the lifting operation of the steel pipe pile section is needed, the second driving motor 515 is started. The second driving motor 515 starts to rotate, and since its shaft is fixedly connected with the input end of the second speed reducer 514, the rotation of the motor shaft will drive the input end of the second speed reducer 514 to rotate synchronously, and then the power generated by the second driving motor 515 is transmitted to the second speed reducer 514.

[0066] After receiving the power from the second driving motor 515, the second speed reducer 514 adjusts the power according to its design parameters (such as speed reduction ratio, etc.). It converts the high-speed and low-torque power input by the second driving motor 515 into low-speed and high-torque power, which is extremely necessary for the work of the lifting hoist 504, because the lifting operation needs large torque to lift heavy objects. Subsequently, the adjusted power is output from the output end of the second speed reducer 514 to the lifting hoist 504 fixedly connected therewith.

[0067] The lifting hoist 504 starts to rotate after receiving the power from the second speed reducer 514. The lifting hoist 504 is in the form of a winding drum, and when it rotates, it drives the lifting cable 505 wound thereon to perform winding action. Since one end of the lifting cable 505 is connected with the hook 506, which is used to hook the steel pipe pile section, as the lifting cable 505 is wound, the hook 506 is lifted, thereby realizing the lifting operation of the steel pipe pile section. Embodiment Two

[0068] In this embodiment, a second clamping assembly 6 is arranged for clamping the steel pipe pile to be welded. In this embodiment, the second clamping assembly 6 is arranged in three groups, and its arrangement principle is the same as that of the first clamping assembly 2, which will not be described here.

[0069] As Figure 10As shown, the second clamping assembly 6 comprises lifting telescopic cylinders 601 and second clamping telescopic cylinders 603. The lifting telescopic cylinders 601 are fixedly arranged on the support frame 1 in a circumferentially equidistant array, and each lifting telescopic cylinder 601 has a connecting plate 602 fixedly arranged at the movable end thereof. This connection enables the telescopic movement of the lifting telescopic cylinders 601 to be directly transmitted to the connecting plate 602, thereby driving the connecting plate 602 to move up and down accordingly.

[0070] A plurality of guide columns 605 are fixedly arranged on the connecting plate 602. These guide columns 605 are fixedly connected with the connecting plate 602, for example, by welding or threaded connection, etc. Meanwhile, guide sleeves 606 are fixedly arranged on the support frame 1, and the guide columns 605 are sleeved in the guide sleeves 606. The cooperation between the guide columns 605 and the guide sleeves 606 plays a guiding and limiting role in the movement of the connecting plate 602, ensuring that the connecting plate 602 can stably move along the predetermined direction under the driving of the lifting telescopic cylinders 601, avoiding unstable conditions such as deviation or shaking.

[0071] The second clamping telescopic cylinders 603 are fixedly arranged on the connecting plate 602. This fixed connection ensures that the second clamping telescopic cylinders 603 can move with the movement of the connecting plate 602 and maintain a stable relative position during the operation. The movable end of each second clamping telescopic cylinder 603 is fixedly arranged with a second clamping plate 604, and this connection enables the telescopic movement of the second clamping telescopic cylinders 603 to drive the second clamping plate 604 to move close to or away from the side wall of the steel pipe pile accordingly.

[0072] In the initial state, the lifting telescopic cylinders 601 and the second clamping telescopic cylinders 603 are in the retracted state, and the second clamping plate 604 maintains a certain distance from the side wall of the steel pipe pile to be welded, without interfering with the hoisting and other operations of the steel pipe pile.

[0073] When the steel pipe pile to be welded is hoisted to the designated position by the hoisting assembly 5, the operation of the second clamping assembly 6 is started. First, the lifting telescopic cylinders 601 are extended by a specified length. Since the bottom of the lifting telescopic cylinders 601 is fixed to the support frame 1 and the movable end is connected with the connecting plate 602, the extension of the lifting telescopic cylinders 601 will drive the connecting plate 602 to move upwards. In this process, the sliding of the guide columns 605 in the guide sleeves 606 plays a guiding role in the movement of the connecting plate 602, ensuring that the connecting plate 602 can accurately move upwards.

[0074] Then, after the connecting plate 602 is moved to the appropriate position, the second clamping telescopic cylinder 603 is extended. The second clamping plate 604 is pushed to approach the side wall of the steel pipe pile to be welded. When the second clamping telescopic cylinder 603 is extended to a certain extent, the second clamping plate 604 will fit the side wall of the steel pipe pile to be welded, thereby fixing it. In this way, through the cooperation of the lifting telescopic cylinder 601 and the second clamping telescopic cylinder 603, the stable clamping of the second clamping assembly 6 to the steel pipe pile to be welded is realized, which provides a stable basis for the subsequent welding operation. Embodiment three

[0075] On the basis of the above-mentioned embodiments, the climbing drive assembly 303 is further described in this embodiment, please refer to Figure 6 The core structure of the climbing drive assembly 303 is the climbing fixed frame 3031, and the climbing wheel 3032 is rotatably arranged on the climbing fixed frame 3031.

[0076] The climbing track 3033 is sleeved on the climbing wheel 3032. The climbing track 3033 is closely sleeved on the outer periphery of the climbing wheel 3032, and there is enough friction between the climbing track 3033 and the climbing wheel 3032, so that the climbing wheel 3032 can drive the climbing track 3033 to move synchronously when rotating. The inner surface shape of the climbing track 3033 matches the outer contour of the climbing wheel 3032, so that the climbing track 3033 can be well matched with the climbing wheel 3032 under various working conditions, and the situation of slipping or falling off will not occur.

[0077] One end of the climbing fixed frame 3031 is fixedly provided with a climbing speed reducer 3034. The climbing drive motor 3035 is fixedly arranged at one end of the climbing speed reducer 3034. The input end of the climbing speed reducer 3034 is fixedly connected with the shaft of the climbing drive motor 3035, and the output end of the climbing speed reducer 3034 is fixedly connected with one of the climbing wheels 3032.

[0078] When the device needs to climb, the climbing telescopic cylinder 302 in the climbing assembly 3 is first driven to operate. The action of the climbing telescopic cylinder 302 drives the climbing connecting rod 301 to move, and since the climbing connecting rod 301 is connected with the climbing drive assembly 303, this movement eventually causes the climbing drive assembly 303 to approach the side wall of the steel pipe pile. When the telescopic cylinder 302 reaches a certain extent, the climbing track 3033 in the climbing drive assembly 303 will fit the steel pipe pile. In this process, the climbing telescopic cylinder 302 plays a role in adjusting the position of the climbing drive assembly 303, ensuring that the climbing drive assembly 303 can accurately establish a contact relationship with the steel pipe pile.

[0079] When the climbing driving assembly 303 is attached to the steel pipe pile, the first clamping telescopic cylinder 203 starts to work to drive the first clamping assembly 2 to be separated from the steel pipe pile. This is because if the first clamping assembly 2 still clamps the steel pipe pile during the climbing process, the climbing movement of the device will be hindered. The action of the first clamping telescopic cylinder 203 drives the clamping connecting rod 201 to rotate reversely, so that the first clamping plate 202 is separated from the side wall of the steel pipe pile, thereby providing the necessary conditions for the climbing of the device.

[0080] After the first clamping assembly 2 is separated from the steel pipe pile, the climbing driving assembly 303 is started. The climbing driving motor 3035 starts to rotate. Since the shaft of the climbing driving motor 3035 is fixedly connected with the input end of the climbing speed reducer 3034, the power generated by the rotation of the motor is transmitted to the climbing speed reducer 3034. The climbing speed reducer 3034 adjusts the power according to its own speed reduction ratio and other parameters, converts the high-speed low-torque power input by the climbing driving motor 3035 into low-speed high-torque power suitable for climbing, and then outputs the adjusted power to the climbing wheel 3032 fixedly connected therewith. After receiving the power, the specific climbing wheel 3032 starts to rotate. Since the climbing wheel 3032 is in close connection with the climbing track 3033, the rotation of the climbing wheel 3032 drives the climbing track 3033 to move. Since the climbing track 3033 is attached to the steel pipe pile and there is a friction force between the climbing track 3033 and the steel pipe pile, the movement of the climbing track 3033 drives the whole device to climb upward along the axial direction of the steel pipe pile. Embodiment Four

[0081] On the basis of the above-mentioned embodiments, in this embodiment, the rotation of the hoisting cross beam 502 is driven by the steering driving motor 510 and other components.

[0082] Referring to Figure 8 , the reinforcing plate 507 is fixedly arranged on the hoisting cross beam 502. The wheel frame 508 is fixedly arranged on the reinforcing plate 507. The wheel frame 508 is installed on the reinforcing plate 507 in a fixed connection manner. The steering wheel 509 is rotatably arranged on the wheel frame 508. The steering wheel 509 is connected with the wheel frame 508 through a shaft. A bearing structure is adopted between the shaft and the wheel frame 508, so that the steering wheel 509 can freely rotate on the wheel frame 508. The steering wheel 509 is in contact with the hoisting support column 501. When the steering wheel 509 rotates, the hoisting cross beam 502 can be driven to rotate through the friction force and rolling action between the steering wheel 509 and the hoisting support column 501.

[0083] The steering driving motor 510 is fixedly arranged on the wheel frame 508. The steering driving motor 510 is installed on the wheel frame 508 in a fixed connection manner. The shaft of the steering driving motor 510 is fixedly connected with the steering wheel 509.

[0084] When the direction of the hoisting cross beam 502 needs to be adjusted, the steering drive motor 510 is started. Since the shaft of the steering drive motor 510 is fixedly connected with the steering wheel 509, when the steering drive motor 510 starts to rotate, the power generated by the motor is directly transmitted to the steering wheel 509.

[0085] When the steering wheel 509 rotates, it will roll on the hoisting support pile. Thus, the hoisting cross beam 502 is driven to rotate on the hoisting stand column. The hoisting cross beam 502 can be accurately adjusted to the required direction to meet the hoisting needs of different positions. Embodiment five

[0086] On the basis of the above-mentioned embodiments, in this embodiment, the annular plate 101 is provided as two arc-shaped plates that can be disassembled to meet the transportation and disassembly of the device.

[0087] The annular plate 101 is composed of a first arc-shaped plate 1011 and a second arc-shaped plate 1012 to form a complete annular structure.

[0088] The first arc-shaped plate 1011 and the second arc-shaped plate 1012 are both provided with a connecting portion 1013 at both ends. A connecting hole 1014 is formed at the position of the connecting portion 1013, and the first arc-shaped plate 1011 and the second arc-shaped plate 1012 are fixedly connected through a connecting pin 1015. The connecting pin 1015 passes through the connecting holes 1014 of the connecting portions 1013 of the two arc-shaped plates to fix the first arc-shaped plate 1011 and the second arc-shaped plate 1012 together.

[0089] The first clamping plate 202 and the second clamping plate 604 are both rotatably provided with a symmetrically arranged auxiliary clamping plate 7. The auxiliary clamping plate 7 and the first clamping plate 202 or the second clamping plate 604 are connected in a rotatable manner, which allows the auxiliary clamping plate 7 to rotate at a certain angle relative to the first clamping plate 202 or the second clamping plate 604. When the clamping plate moves close to the position of the steel pipe pile, the rotation of the auxiliary clamping plate 7 can better fit the side wall of the steel pipe pile, so that the device can be more stably fixed on the steel pipe pile.

[0090] The fitting position of the auxiliary clamping plate 7 and the steel pipe pile is fixedly provided with an anti-skid layer 701. A plurality of anti-skid strips 30331 are fixedly provided on the climbing crawler 3033. The anti-skid layer 701 and the anti-skid strips 30331 can better fit the device with the steel pipe pile. The material of the anti-skid layer 701 and the anti-skid strips 30331 is not limited here, and the operator can set the material and the texture of the anti-skid layer 701 and the anti-skid strips 30331 according to the actual situation.

[0091] A reinforcing rib 8 is fixedly arranged between the annular plate 101 and the support stand column 102. The two ends of the reinforcing rib 8 are connected with the annular plate 101 and the support stand column 102, respectively, to enhance the connection strength between the annular plate 101 and the support stand column 102.

[0092] The bottom of the support column 102 is fixedly provided with a support leg 9. The main role of the support leg 9 is to provide a stable support foundation for the entire device. In the outdoor welding operation environment of the offshore wind power steel pipe pile, the support leg 9 needs to be able to adapt to different ground conditions.

[0093] Working principle: in the process of use, first, the device is installed on the steel pipe pile base, which is the starting point of the entire operation and provides a basic platform for subsequent operations.

[0094] The device is clamped on the fixed steel pipe pile by the first clamping assembly 2. The first clamping assembly 2 drives the clamping connecting rod 201 to rotate through the extension and retraction of the first clamping telescopic cylinder 203, so that the first clamping plate 202 is attached to or separated from the side wall of the steel pipe pile, and stable clamping is realized, thereby providing a stable support foundation for subsequent lifting and welding operations.

[0095] When it is necessary to install and weld the next section of the steel pipe pile, as shown in Figure 11 , the lifting assembly 5 lifts the steel pipe pile to be welded from one side, and then the lifting cross beam 502 rotates on the lifting support column 501 to adjust the direction. The lifting trolley 503 slides on the lifting cross beam 502 to adjust the horizontal position, the lifting winch 504 controls the extension and retraction of the lifting cable 505 through rotation, and the lifting hook 506 is connected to the lifting cable 505, as shown in Figure 12 , so as to lift the steel pipe pile section above the steel pipe pile base.

[0096] When the steel pipe pile section is lifted to the specified position, the second clamping assembly 6 starts to work. The lifting telescopic cylinders 601 extend to a specified length, drive the connecting plate 602 to rise, and then the second clamping telescopic cylinder 603 extends, so that the second clamping plate 604 is attached to the side wall of the steel pipe pile to be welded, and the fixing of the steel pipe pile section is completed, thereby preparing for the welding operation.

[0097] The annular guide rail 401 in the welding assembly 4 is fixed on the support frame 1, the annular driving slide 402 can slide on the annular guide rail 401, and the welding robot 403 is fixed on the annular driving slide 402. The sliding of the annular driving slide 402 drives the welding robot 403 to make a circular motion around the steel pipe pile, so as to weld the steel pipe pile section.

[0098] After welding, the climbing assembly 3 starts to work. The climbing telescopic cylinder 302 first drives the climbing connecting rod 301, so that the climbing driving assembly 303 is attached to the steel pipe pile. Then the first clamping telescopic cylinder 203 drives the first clamping assembly 2 to separate from the steel pipe pile to avoid interference with the climbing. The climbing driving motor 3035 in the climbing driving assembly 303 drives the climbing wheel 3032 to rotate through the climbing speed reducer 3034, and the climbing track 3033 on the climbing wheel 3032 moves, thereby driving the device to climb along the steel pipe pile in the axial direction.

[0099] After climbing to the next welding position, the first clamping telescopic cylinder 203 drives the first clamping assembly 2 to contact the steel pipe pile again, and the device is clamped on the steel pipe pile by the first clamping assembly 2 again. Then the hoisting assembly 5 hoists the next section of steel pipe pile section above the steel pipe pile base again, and the steps of fixing, welding, device climbing, etc. of the steel pipe pile section are repeated, and the cycle is continued until the whole wind power steel pipe pile welding work is completed.

[0100] Although embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
