Description

Technical Field

[0001] This utility model belongs to the technical field of toothed bar processing device, specifically a toothed bar surface processing device for offshore wind turbine base. Background Technology

[0002] In the construction of offshore wind turbines, the base toothed rod is a core load-bearing component, and its surface treatment quality directly affects the long-term stability and safety performance of the entire unit in harsh marine environments. Due to the special high-salt, high-humidity, and corrosive environment at sea, international standards have imposed stringent requirements on the surface finish of the toothed rod, which must completely eliminate surface defects such as burrs and stains generated during processing. However, some toothed rods still have burrs and processing stains on their surfaces. These microscopic defects can become stress concentration points under long-term salt spray erosion, accelerating the formation of metal fatigue cracks. In particular, offshore wind power projects require toothed rods of various specifications, while traditional polishing equipment usually uses a polishing wheel design with a fixed spacing. This design cannot guarantee sufficient contact pressure for small-diameter toothed rods and is prone to over-polishing large-diameter toothed rods. Therefore, improvements are needed to address the current situation. Utility Model Content

[0003] To address the above issues and overcome the shortcomings of existing technologies, this utility model provides a surface processing device for the toothed rods of offshore wind turbine bases. This effectively solves the problem that in offshore wind turbine construction, the surface treatment quality of the toothed rods, as a core load-bearing component, directly affects the long-term stability and safety performance of the entire unit in harsh marine environments. Due to the unique high-salt, high-humidity, and corrosive environment at sea, international standards impose stringent requirements on the surface finish of the toothed rods, necessitating the complete elimination of surface defects such as burrs and stains generated during processing. However, some toothed rod surfaces still have burrs and processing stains. These microscopic defects, under long-term salt spray erosion, become stress concentration points, accelerating the formation of metal fatigue cracks. Furthermore, offshore wind power projects require toothed rods of various specifications, while traditional polishing equipment typically uses a fixed-gap polishing wheel design. This not only fails to guarantee sufficient contact pressure for small-diameter toothed rods but also easily causes over-polishing of large-diameter toothed rods.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a surface processing device for the toothed rod of an offshore wind turbine base, comprising a worktable, an electric telescopic tube, and a base. The electric telescopic tubes on both sides are connected to both sides of the inner cavity of the worktable, and the top of the electric telescopic tubes on both sides are connected to the base. A processing component is provided inside the worktable, and a conveying component is provided on the left side of the top of the worktable.

[0005] The processing assembly includes mounting shafts, both sides of which are connected to the inner cavity of the worktable. Mounting brackets are connected to the outer walls of both mounting shafts. Polishing wheels are connected to the top of both mounting brackets. A first motor is mounted on the left side of both mounting brackets and is connected to the polishing wheel. A support wheel is connected to the top of the base. Guide wheels are connected to the bottom of both mounting brackets. A control panel is connected to the front of the worktable.

[0006] Preferably, the mounting brackets on both sides are symmetrically arranged, and the distance between the polishing wheels and the support wheels on both sides is equal.

[0007] Preferably, auxiliary wheels are connected to both sides of the inner cavity of the workbench, and the mounting brackets on both sides are in contact with the auxiliary wheels on both sides.

[0008] Preferably, the top of the workbench is connected to a protective cover, which is made of transparent material.

[0009] Preferably, both sides of the inner cavity of the workbench are connected to limit rods, and both limit rods penetrate the body of the base.

[0010] Preferably, the conveying assembly includes a connecting shaft, with both connecting shafts connected to the top of the worktable on both sides. The outer walls of the connecting shafts on both sides are provided with conveyor belts, and synchronous pulleys are provided at the connection points between the conveyor belts and the connecting shafts on both sides. A second motor is installed on the front side of the worktable, and the second motor is connected to the connecting shaft on the right side. An inclined block is connected to the top of the worktable.

[0011] Preferably, the top of the workbench is provided with a storage slot, which is located in front of the conveyor belt.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When the polishing device is working, the operator inserts the toothed strip to be processed through the right side of the worktable and places it on the support wheel. The operator then activates the electric telescopic tube via the control panel to push the support wheel upward, clamping the toothed strip between the support wheel and the polishing wheels on both sides. The guide wheel stabilizes the mounting frame from below, and the motor drives the polishing wheels to rotate at high speed to polish both sides of the toothed strip simultaneously. During the processing, the toothed strip is automatically conveyed to the left until the surface treatment is completed.

[0014] 2. For machining threaded rods of different diameters, the electric telescopic tube adjusts the height of the support wheels by raising and lowering them, while simultaneously driving the guide wheels to rotate the mounting bracket, causing the polishing wheels on both sides to move towards the center. This three-way clamping structure ensures stable polishing pressure for threaded rods of different specifications, guaranteeing consistent machining quality.

[0015] 3. After processing, the toothed strip falls onto the conveyor belt under gravity, and the motor drives the conveyor belt to transport the toothed strip to the left. When the left end of the toothed strip contacts the inclined block, it automatically slides off, making it easy for workers to collect and automating the polishing process.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5A surface processing device for the toothed strip of an offshore wind turbine base includes a worktable 100, an electric telescopic tube 200, and a base 201. The electric telescopic tubes 200 on both sides are fixedly connected to the two sides of the inner cavity of the worktable 100. The top of the electric telescopic tubes 200 on both sides is fixedly connected to the base 201. A processing component is provided inside the worktable 100, and a conveying component is provided on the left side of the top of the worktable 100.

[0026] The processing components include mounting shafts 202, with both sides of the mounting shafts 202 rotatably connected to the two sides of the inner cavity of the worktable 100. Mounting brackets 203 are fixedly connected to the outer walls of both mounting shafts 202. Polishing wheels 204 are rotatably connected to the top of both mounting brackets 203. A first motor 205 is fixedly mounted on the left side of both mounting brackets 203, and the first motor 205 is connected to the polishing wheel 204. A support wheel 206 is rotatably connected to the top of the base 201, and guide wheels 207 are rotatably connected to the bottom of both mounting brackets 203. A control panel 208 is fixedly connected to the front of the worktable 100, and the control panel 208 is electrically connected to the two electric telescopic tubes 200. First, the threaded rod to be processed is inserted from the right side of the worktable 100 into the support wheel 206. The two electric telescopic tubes 200 are activated via the control panel 208, pushing the base 201 and support wheel 206 upwards, causing the threaded rod to... Clamped between the support wheel 206 and the polishing wheels 204 on both sides, and with the guide wheel 207 providing stable support for the mounting brackets 203 on both sides from below, the first motor 205 drives the polishing wheel 204 to rotate at high speed, simultaneously polishing the surfaces on both sides of the toothed strip. During the polishing process, the toothed strip is automatically conveyed to the left until it reaches the outer side of the worktable 100, thus completing the polishing of burrs and stains on the outer wall of the toothed strip. When processing toothed strips of different diameters, the extension of the electric telescopic tubes 200 on both sides drives the base 201 and the support wheel 206 to rise. During the rise of the base 201, the guide wheels 207 on both sides rotate along the outer wall of the base 201, causing the mounting brackets 203 on both sides to rotate, and the polishing wheels 204 on both sides to move towards the center. This ensures that toothed strips of different diameters are subjected to clamping forces in three directions: obliquely upwards and downwards, ensuring that toothed strips of different diameters receive consistent polishing pressure and making the polishing process of the toothed strip more stable.

[0027] The mounting brackets 203 on both sides are symmetrically arranged, and the distance between the polishing wheels 204 and the support wheels 206 on both sides is equal. The symmetrical layout ensures that the toothed strip is subjected to balanced force during polishing, avoiding deformation or uneven surface due to excessive pressure on one side, and improving processing accuracy and consistency.

[0028] Auxiliary wheels 209 are rotatably connected to both sides of the inner cavity of the workbench 100, and the mounting brackets 203 on both sides are in contact with the auxiliary wheels 209, so that the mounting brackets 203 on both sides can rotate more stably.

[0029] The top of the workbench 100 is rotatably connected to a protective cover 210. The protective cover 210 is made of transparent material, and metal shavings or dust generated during the polishing process will be blocked by the protective cover 210 to avoid injury to the operator.

[0030] Limiting rods 211 are fixedly connected to both sides of the inner cavity of the workbench 100. Both limiting rods 211 penetrate the body of the base 201, thereby making the up-and-down movement of the base 201 more stable.

[0031] The conveying assembly includes connecting shafts 300, with both sides of the connecting shafts 300 rotatably connected to the top of the workbench 100. Conveyor belts 301 are sleeved on the outer walls of the connecting shafts 300 on both sides. Synchronous pulleys are provided at the connection points between the conveyor belts 301 and the connecting shafts 300 on both sides. A second motor 302 is fixedly installed on the front side of the workbench 100 and is connected to the right connecting shaft 300. An inclined block 303 is fixedly connected to the top of the workbench 100. By starting the second motor 302, the right connecting shaft 300 is driven to rotate, causing the conveyor belt 301 to circulate on the connecting shafts 300 on both sides. When the toothed strip is processed, it falls to the top of the conveyor belt 301 under the action of gravity. As the second motor 302 continues to run, the conveyor belt 301 conveys the processed toothed strip to the left at a constant speed. During the conveying process, the left end of the toothed strip contacts the inclined block 303, causing it to automatically slide off the conveyor belt 301, thus facilitating the collection of the processed toothed strip by the workers.

[0032] The top of the workbench 100 is provided with a storage groove 304, which is located in front of the conveyor belt 301, so that the finished toothed strips can roll directly into the storage groove 304 for easy access by the workers.

[0033] Working principle: First, the toothed rod to be processed is inserted from the right side of the worktable 100 into the support wheel 206. The electric telescopic tubes 200 on both sides are activated via the control panel 208, pushing the base 201 and support wheel 206 upwards, clamping the toothed rod between the support wheel 206 and the polishing wheels 204 on both sides. Simultaneously, the guide wheel 207 stably supports the mounting brackets 203 on both sides from below. The first motor 205 drives the polishing wheels 204 to rotate at high speed, simultaneously polishing the surfaces of both sides of the toothed rod. During polishing, the toothed rod is automatically conveyed to the left until it reaches the outer side of the worktable 100, thus completing the polishing of burrs and stains on the outer wall of the toothed rod. When processing toothed rods of different diameters, the extension of the electric telescopic tubes 200 on both sides drives the base 201 and support wheel 206 upwards. During the upward movement of the base 201, the guide wheels 207... Guide rollers 207 rotate along the outer wall of base 201, causing the mounting brackets 203 on both sides to rotate. This moves the polishing wheels 204 on both sides towards the center, subjecting the toothed strips of different diameters to clamping forces from three directions: the upper sides, the bottom, and the sides. This ensures that toothed strips of different diameters receive consistent polishing pressure, making the polishing process more stable. By starting the second motor 302, the right connecting shaft 300 is driven to rotate, causing the conveyor belt 301 to circulate on the connecting shafts 300 on both sides. After the toothed strip is processed, it falls to the top of the conveyor belt 301 under the action of gravity. As the second motor 302 continues to run, the conveyor belt 301 transports the processed toothed strip to the left at a constant speed. During the transport process, the left end of the toothed strip contacts the inclined block 303, causing it to automatically slide off the conveyor belt 301, making it easier for workers to collect the processed toothed strip.
