Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering equipment maintenance technology, specifically to an in-situ repair technology for the anti-corrosion coating of dam gates. Background Technology

[0002] As a core control component of water conservancy projects, dam gates are in underwater or alternating wet and dry environments for a long time, facing multiple corrosion factors such as electrochemical corrosion (chloride ions destroying the oxide film, dissolved oxygen / carbon dioxide reaction), physical wear (silt impact), and biological corrosion (microbial acid production).

[0003] Traditional anti-corrosion technologies mainly rely on coating protection (such as epoxy zinc-rich paint, which fails in 3-5 years), thermal spraying of zinc / aluminum (requires sandblasting pretreatment, which is costly), and cathodic protection (dependent on continuous power supply). However, these technologies have the following drawbacks when used for repair:

[0004] 1. Manual repair requires the erection of scaffolding, which poses risks of falls from heights and poisoning. The work cycle is long (e.g., 27 days for a certain reservoir) and inefficient. Especially when the gate is wide, the scaffolding needs to be moved, making the erection even more inconvenient.

[0005] 2. Traditional robot repair relies on electromagnetic adsorption (requires continuous power supply) or permanent magnet adsorption (adsorption force is not adjustable) to fix the robot and prevent it from falling. It cannot adapt to complex curved gates such as arcs and streamlines, and is prone to insufficient repair accuracy due to shaking. Utility Model Content

[0006] The purpose of this invention is to solve the problems of high risk, low efficiency and inability to adapt to complex curved gates in traditional repair technologies, and to provide an in-situ repair technology for anti-corrosion coatings of dam gates based on dual positioning of magnetic adsorption and rope system.

[0007] To achieve the above objectives, this utility model provides an in-situ repair device for the anti-corrosion coating of a gate, with the width direction of the gate as the left and right direction. It includes a suspension walking mechanism and a wall-attaching repair mechanism. The suspension walking mechanism is connected to the dam on both sides of the top of the gate and is used to suspend and adjust the left and right position of the wall-attaching repair mechanism. The wall-attaching repair mechanism is used to repair the corroded areas on the surface of the gate.

[0008] The suspended traveling mechanism includes a traveling frame with a horizontal steel wire rope passing through it. The horizontal steel wire rope extends in the left and right direction and its two ends are anchored to the dam on both sides of the top of the gate during operation.

[0009] The traveling frame is equipped with an upper traveling wheel set and a lower traveling wheel set relative to the horizontal steel wire rope. The upper and lower traveling wheel sets are symmetrically arranged and each includes at least two traveling wheels. The traveling wheels of the upper traveling wheel set correspond one-to-one with the traveling wheels of the lower traveling wheel set, and the two corresponding traveling wheels clamp the horizontal steel wire rope in the vertical direction.

[0010] One of the traveling wheels is an active traveling wheel. One end of the axle of the active traveling wheel is connected to the traveling frame via a bearing, and the other end of the axle of the active traveling wheel is connected to a remote-controlled geared motor via a coupling. The remote-controlled geared motor is equipped with a first remote controller. The remote-controlled geared motor is fixed on the traveling frame.

[0011] The other traveling wheels are passive traveling wheels, and both ends of the axle of the passive traveling wheels are connected to the traveling frame through bearings; the traveling frame is connected downwards to a suspension steel wire rope, which is connected downwards to the wall-adhering repair mechanism.

[0012] The walking frame is also equipped with an upper battery, which is connected to and powers the remote-controlled geared motor.

[0013] The wall-mounted repair mechanism includes a housing, with an electric winch mounted on the top of the housing. The wire rope of the electric winch extends upward and connects to the bottom of the traveling frame, serving as the suspension wire rope. The wall-mounted repair mechanism is suspended from the traveling frame via the suspension wire rope. Inside the housing are a lower battery and an electronic control device. The lower battery is connected to and powers both the electric winch and the electronic control device. The electronic control device connects to and controls the electric winch. The electronic control device is connected to a wireless communication module, which communicates with the BLYNK display terminal. The wireless communication module is connected to and powered by the lower battery.

[0014] The left end of the housing of the wall-mounted repair mechanism is equipped with an electric grinder, with the grinding head of the electric grinder facing the gate surface; an electric dust gun is installed in the housing adjacent to the electric grinder, with the air outlet of the electric dust gun facing the grinding area of ​​the electric grinder and used to blow away the debris generated during grinding.

[0015] The shell has an anti-corrosion coating tank and an electric spray gun connected to the anti-corrosion coating tank in the middle. The anti-corrosion coating tank is used to store anti-corrosion coating, and the electric spray gun faces the gate surface and is used to spray anti-corrosion coating onto the gate surface after grinding and blowing.

[0016] The lower battery connects to and powers the electric grinder, electric blow gun, and electric spray gun, while the electronic control device connects to and controls the electric grinder, electric blow gun, and electric spray gun.

[0017] The upper right side of the housing of the wall-mounted repair mechanism is equipped with an upper roller, and the lower right side of the housing is equipped with a lower roller. Both the upper roller and the lower roller are used to form a rolling fit with the gate surface. The upper roller is located above the spraying range of the electric spray gun, and the lower roller is located below the spraying range of the electric spray gun.

[0018] An auxiliary wire rope is installed above and below the horizontal wire rope, and the auxiliary wire ropes are parallel to the horizontal wire rope;

[0019] The traveling frame is equipped with two upper and lower sliding sleeves that correspond one-to-one with the auxiliary steel wire ropes. The auxiliary steel wire ropes pass through the sliding sleeves accordingly. The two ends of the auxiliary steel wire ropes extend in the left and right directions and are anchored to the dam on both sides of the top of the gate during operation.

[0020] The left side of the wall-mounted repair mechanism is equipped with two electromagnets spaced apart vertically. The two electromagnets are used to press the grinding head of the electric grinder against the gate surface through magnetic attraction.

[0021] This utility model has the following advantages:

[0022] This invention eliminates the need for scaffolding for repair work, resulting in high efficiency and low cost. It also eliminates the reliance on the magnetic attraction of the repair mechanism itself for support, overcoming the risks of falling and inability to adapt to curved gate surfaces inherent in previous magnetic support methods. Furthermore, it eliminates the need for manual climbing, thus avoiding the personal safety risks associated with such work.

[0023] The suspended traveling mechanism is easy to install and use. During installation, simply anchor both ends of the horizontal steel wire rope to the dam on both sides of the top of the gate. During use, operators do not need to approach the suspended traveling mechanism; they can control the active traveling wheel to rotate forward or backward via a remote control, thus moving it left or right along the steel wire rope.

[0024] The BLYNK display terminal can control the forward, reverse, locking, and unlocking operations of the electric winch, thereby controlling the vertical height of the wall-mounted repair mechanism and providing a basis for repairing the gate at different heights.

[0025] The specific structure of the wall-mounted repair mechanism allows staff to remotely control it via the BLYNK display terminal, enabling integrated operations of grinding, blowing cleaning, and electric spraying. This improves the repair efficiency of the gate surface while ensuring repair quality.

[0026] The upper and lower rollers facilitate the movement of the wall-mounted repair mechanism along the gate surface while avoiding damage to the freshly sprayed anti-corrosion coating.

[0027] Two auxiliary steel wire ropes significantly improve the stability of this utility model during operation, preventing abnormal posture of the walking frame during operation.

[0028] When the electromagnet is activated, the electric grinder on the left is subjected to high pressure, thus ensuring the grinding quality; the roller on the right is subjected to low pressure, reducing the resistance to movement. Attached Figure Description

[0034] The suspended traveling mechanism includes a traveling frame 1, through which a horizontal steel wire rope 2 passes. The horizontal steel wire rope 2 extends in the left and right direction and its two ends are anchored to the dam on both sides of the top of the gate during operation.

[0037] The other traveling wheels are passive traveling wheels 4, and both ends of the axle of the passive traveling wheels 4 are connected to the traveling frame 1 through bearings 5;

[0038] The traveling frame 1 is connected downwards to a suspension steel cable 8, which in turn is connected downwards to the wall-adhering repair mechanism, thereby adjusting the left and right positions of the wall-adhering repair mechanism. The traveling frame 1 also contains an upper battery 9, which is connected to and powers the remote-controlled reduction motor 7.

[0039] The suspended traveling mechanism is easy to install and use. During installation, simply anchor both ends of the horizontal steel wire rope 2 to the dam on both sides of the top of the gate. During use, operators do not need to approach the suspended traveling mechanism; they can control the active traveling wheel 3 to rotate forward or backward via a remote control, thereby moving it left or right along the steel wire rope.

[0040] The wall-mounted repair mechanism includes a housing 10, with an electric winch 11 mounted on the top of the housing 10. The wire rope of the electric winch 11 extends upward and connects to the bottom of the traveling frame 1. The wire rope of the electric winch 11 serves as the suspension wire rope 8.

[0041] The wall-mounted repair mechanism is suspended on the suspension travel mechanism by a suspension steel wire rope 8; the housing 10 is equipped with a lower battery 12 and an electronic control device 13. The lower battery 12 is connected to and supplies power to the electric winch 11 and the electronic control device 13. The electronic control device 13 is connected to and controls the electric winch 11. The electronic control device 13 is connected to a wireless communication module 14. The electronic control device 13 communicates with the BLYNK display terminal through the wireless communication module 14. The wireless communication module 14 is connected to the lower battery 12 and is powered by the lower battery 12.

[0042] The electronic control device 13 preferably uses an Arduino Uno development board with a built-in BLYNK library, but other Arduino microcontrollers with BLYNK libraries can also be used. The BLYNK display terminal is preferably a smartphone with the BLYNK application (APP) installed. The wireless communication module 14 is preferably a 4G or 5G module. The wireless communication module 14 can be powered directly by a battery or by the Arduino Uno development board.

[0043] The BLYNK display terminal can control the forward, reverse, locking, and unlocking operations of the electric winch 11, thereby controlling the vertical height of the wall-mounted repair mechanism and providing a basis for repairing the gate at different heights.

[0044] An electric grinder 15 is provided at the left end of the housing 10 of the wall-mounted repair mechanism. The grinding head 16 of the electric grinder 15 faces the gate surface. An electric dust gun 17 is installed in the housing 10 adjacent to the electric grinder 15.

[0045] The housing 10 has an anti-corrosion coating tank 18 and an electric spray gun 19 connected to the anti-corrosion coating tank 18 in the middle.

[0046] The lower battery 12 connects to and powers the electric grinder 15, the electric blow gun 17, and the electric spray gun 19. The electronic control device 13 connects to and controls the electric grinder 15, the electric blow gun 17, and the electric spray gun 19.

[0047] The specific structure of the wall-mounted repair mechanism allows staff to remotely control it via the BLYNK display terminal, enabling integrated operations of grinding, blowing cleaning, and electric spraying. This improves the repair efficiency of the gate surface while ensuring repair quality.

[0048] The upper right side of the housing 10 of the wall-mounted repair mechanism is provided with an upper roller 20, and the lower right side of the housing 10 is provided with a lower roller 21.

[0049] The upper roller 20 and the lower roller 21 can facilitate the movement of the wall-mounted repair mechanism along the gate surface, while avoiding damage to the newly sprayed anti-corrosion coating.

[0050] An auxiliary wire rope 22 is provided above and below the horizontal wire rope 2, and the auxiliary wire rope 22 is parallel to the horizontal wire rope 2.

[0051] The traveling frame 1 is equipped with two upper and lower sliding sleeves 23 corresponding to the auxiliary steel wire rope 22. The auxiliary steel wire rope 22 passes through the sliding sleeves 23. The two ends of the auxiliary steel wire rope 22 extend in the left and right direction and are anchored to the dam on both sides of the top of the gate during operation.

[0052] The two auxiliary steel wire ropes 22 significantly improve the stability of this utility model during operation, preventing abnormal posture of the traveling frame 1 during operation. After the work is completed, the anchoring structures at both ends of each steel wire rope can be disassembled. The two auxiliary steel wire ropes 22 and the horizontal steel wire rope 2 do not need to be removed from the traveling frame 1, but can be coiled up and stored together with the traveling frame 1 for convenient use next time.

[0053] The housing 10 of the wall-mounted repair mechanism has two electromagnets 24 spaced vertically on its left side. The two electromagnets 24 are used to press the grinding head 16 of the electric grinder 15 against the gate surface through magnetic attraction. When the electromagnets 24 are activated, the electric grinder 15 on the left side is subjected to greater pressure, thereby ensuring the grinding quality; the roller on the right side is subjected to less pressure, reducing the resistance to movement.

[0054] The working process of this utility model for repairing the anti-corrosion coating of dam gates is as follows:

[0055] I. Equipment Installation Phase

[0056] Installation of the suspended traveling mechanism: Extend the horizontal steel wire rope 2 along the width direction (left and right direction) of the gate and anchor both ends to the dam on both sides of the top of the gate; add a parallel auxiliary steel wire rope 22 above and below the horizontal steel wire rope 2, and anchor both ends of the auxiliary steel wire rope 22 to the dam to make the posture of the suspended traveling mechanism more stable during operation.

[0057] The traveling frame 1 is pre-mounted on the horizontal steel wire rope 2, and the horizontal steel wire rope 2 is clamped by the upper and lower traveling wheel sets (multiple traveling wheels arranged symmetrically) inside the traveling frame 1; at the same time, the upper and lower sliding sleeves 23 inside the traveling frame 1 pass through two auxiliary steel wire ropes 22 respectively to improve stability.

[0058] Wall-adhering repair mechanism connection: Connect the wall-adhering repair mechanism to the bottom of the walking frame 1 via the suspension steel wire rope 8 to complete the overall assembly of the suspended walking mechanism and the wall-adhering repair mechanism.

[0059] II. Repair Operation Phase

[0060] Position initialization operation: The remote control of the remote control reduction motor 7 (forward and reverse motor) of the suspension walking mechanism is controlled by the first remote control to drive the active walking wheel 3 to move along the horizontal steel wire rope 2, and adjust the wall-attached repair mechanism to the starting repair position on the right side of the area to be repaired on the gate surface.

[0061] Vertical height adjustment operation: Send instructions to the electrical control device 13 (such as Arduino Uno development board) of the wall-mounted repair mechanism via the BLYNK display terminal (such as a mobile APP) to control the electric winch 11 to raise and lower the suspension steel wire rope and adjust the wall-mounted repair mechanism to the target repair height.

[0062] Polishing and cleaning:

[0063] The electromagnets 24 (two on the left side, one above the other) of the wall-mounted repair mechanism are activated by the BLYNK display terminal and the electronic control device 13, and the grinding head 16 of the electric grinder 15 is pressed tightly against the gate surface by magnetic attraction.

[0064] The electric grinder 15 is started by controlling the BLYNK display terminal and the electronic control device 13 to grind the corroded area.

[0065] Simultaneously start the electric blower 17 and the electric spray gun 19. The electric blower 17 blows airflow into the grinding area to remove the debris generated during grinding. After the electric spray gun 19 is started, it evenly sprays the anti-corrosion coating in the anti-corrosion coating tank 18 onto the surface of the gate after grinding and cleaning.

[0066] The remote-controlled reduction motor 7 drives the entire utility model to move slowly to the left. During the movement, grinding, blowing cleaning and anti-corrosion spraying are continuously carried out until it reaches the left end of the area to be repaired on the gate surface, and the repair work of the current height area is completed.

[0067] 3. Repeat step 2 after changing the working height.

[0068] Changing the working height is:

[0069] By shutting off the electromagnet 24, electric blow gun 17, and electric spray gun 19 via the BLYNK display terminal and electronic control device 13, the aforementioned position initialization and vertical height adjustment operations are performed again, adjusting the wall-mounted repair mechanism to the right-hand starting repair position of the new target repair height. Then, the second step is repeated.

[0070] Repeat steps two and three until all areas on the gate surface to be repaired have been repaired.

[0071] IV. End of Operation: Finally, disassemble the anchoring structure of each wire rope, coil the wire rope and store it together with the walking frame 1 for easy use next time.

[0072] The above embodiments are only used to illustrate and not limit the technical solutions of this utility model. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the utility model without departing from the spirit and scope of the utility model.
