Description

Technical Field

[0001] This utility model relates to the field of hydraulic gate technology, specifically an automatic welding device for hydraulic gates. Background Technology

[0002] Hydraulic gates are hydraulic structures used to regulate water levels and control flow. They are low-head hydraulic structures built on rivers and canals to control flow and regulate water levels. By opening and closing the gates, functions such as water storage and flood discharge are achieved, and they are widely used in water conservancy projects.

[0003] Currently, water conservancy gates require welding and assembly during the production process. However, due to the considerable height of the gates, manual welding often requires climbing up and down to adjust the welding position, making it difficult to quickly weld the highest points of the gates and easily leading to reduced welding efficiency.

[0004] To address these issues, we have developed an automatic welding device for hydraulic gates. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an automatic welding device for hydraulic gates.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic welding device for a hydraulic gate, comprising a base plate, a welding mechanism disposed above the base plate, the welding mechanism comprising a fixing plate, a control panel fixedly connected to the upper surface of the base plate, a sliding groove formed on one side of the fixing plate, a hydraulic telescopic rod fixedly connected to the inner wall of the sliding groove, a sliding block fixedly connected to the telescopic end of the hydraulic telescopic rod, a fixing rod fixedly connected to one side of the sliding block, a connecting block fixedly connected to the end of the fixing rod away from the sliding block, a welding head fixedly connected to one side of the connecting block, and an industrial camera fixedly connected to the upper surface of the connecting block.

[0007] Furthermore, a reinforcing frame is fixedly connected to the outer surface of the control panel, and the bottom surface of the reinforcing frame is fixedly connected to the upper surface of the base plate.

[0008] Furthermore, four brake wheels are fixedly connected to the bottom surface of the base plate, and two fixing rings are fixedly connected to the outer surface of each set of brake wheels. The top of each set of fixing rings is fixedly connected to the bottom surface of the base plate.

[0009] Furthermore, a reinforcing plate is fixedly connected to the outer surface of the fixing rod, and one side of the reinforcing plate is fixedly connected to one side of the sliding block.

[0010] Furthermore, the inner wall of the reinforcing plate is threaded with four fixing bolts, and the outer surface of each set of fixing bolts is threadedly connected to the inner wall of the sliding block.

[0011] Furthermore, a push handle is fixedly connected to the upper surface of the base plate, and a protective seat is fixedly connected to the outer surface of the hydraulic telescopic rod. The bottom surface of the protective seat is fixedly connected to the inner wall of the slide groove.

[0012] Compared with existing technologies, this automatic welding device for hydraulic gates has the following advantages:

[0013] 1. This utility model, by setting up a welding mechanism in combination with a hydraulic telescopic rod and a sliding block, forms a welding execution system with flexible height adjustment. The hydraulic telescopic rod can drive the sliding block to rise and fall stably along the groove of the fixed plate, thereby driving the fixed rod, connecting block and welding head to adjust their height synchronously. This design completely gets rid of the traditional operation mode of "manual climbing to adjust the welding position". There is no need for workers to repeatedly go up and down. It can quickly cover the full range of welding needs of the gate from low to high, and avoid the risk of falling during the climbing process. It significantly improves the efficiency and safety of welding operations, and is especially suitable for welding scenarios of large water conservancy gates with high height.

[0014] 2. This utility model provides visual monitoring support for the welding process by setting an industrial camera fixed on the upper surface of the connecting block. Workers can observe the alignment of the welding head and the weld in real time through the control panel without close-range visual observation, avoiding the harm to personnel caused by high welding temperature and strong light. It can also accurately control the welding trajectory and fusion effect. Compared with the method of judging the welding position by human experience, this design effectively reduces quality problems such as "alignment deviation", "missed weld" and "false weld", ensuring the sealing performance and structural strength of the weld of the hydraulic gate.

[0021] This embodiment provides an automatic welding device for hydraulic gates. This device facilitates welding work at high points on the gate, effectively improves welding efficiency, prevents workers from climbing up and down, saving time and effort, and enhances the practicality of the device.

The reinforcing frame 4 can reinforce the control panel 203 and enhance the stability of the device.

[0023] Reference Figure 1 , Figure 2 and Figure 4 A sliding groove 202 is provided on one side of the fixed plate 201. A hydraulic telescopic rod 204 is fixedly connected to the inner wall of the sliding groove 202. Four brake wheels 8 are fixedly connected to the bottom surface of the base plate 1. Two fixing rings 9 are fixedly connected to the outer surface of each set of brake wheels 8. The top of each set of fixing rings 9 is fixedly connected to the bottom surface of the base plate 1. Through the brake wheels 8 and fixing rings 9, the overall position of the device can be adjusted and moved, thereby enhancing the applicability of the device.

[0024] Reference Figure 2 and Figure 3 The telescopic end of the hydraulic telescopic rod 204 is fixedly connected to a sliding block 205. A fixed rod 207 is fixedly connected to one side of the sliding block 205. A reinforcing plate 6 is fixedly connected to the outer surface of the fixed rod 207. One side of the reinforcing plate 6 is fixedly connected to one side of the sliding block 205. The reinforcing plate 6 can reinforce the fixed rod 207 and the sliding block 205 to prevent them from swaying during use.

[0025] Reference Figure 3A connecting block 206 is fixedly connected to the end of the fixing rod 207 away from the sliding block 205. A welding head 209 is fixedly connected to one side of the connecting block 206. Four fixing bolts 7 are threadedly connected to the inner wall of the reinforcing plate 6. The outer surface of each set of fixing bolts 7 is threadedly connected to the inner wall of the sliding block 205. The position of the reinforcing plate 6 can be fixed by the fixing bolts 7, which plays the role of fixing and limiting.

[0026] Reference Figure 1 , Figure 2 and Figure 3 An industrial camera 208 is fixedly connected to the upper surface of the connecting block 206, a push handle 3 is fixedly connected to the upper surface of the base plate 1, a protective seat 5 is fixedly connected to the outer surface of the hydraulic telescopic rod 204, and the bottom surface of the protective seat 5 is fixedly connected to the inner wall of the slide groove 202. The protective seat 5 can protect the hydraulic telescopic rod 204 and prevent it from being damaged by the outside during use.

[0027] Working principle: When in use, first push the push handle 3 on the base plate 1, and use the brake wheel 8 to move the device to the front of the area to be welded on the hydraulic gate. Then, step on the brake pedal of the brake wheel 8 to lock the brake wheel 8 and prevent the device from shifting due to vibration during operation. If the gate weld is longitudinal, it is necessary to ensure that the vertical distance between the device and the gate is consistent. This can be observed through the screen of the industrial camera 208. The operator observes the real-time screen transmitted by the industrial camera 208 in front of the control panel 203 and clicks the "lifting adjustment" button to start the hydraulic telescopic rod 204. The hydraulic telescopic rod 204 drives the sliding block 205 to slowly rise and fall along the slide groove 202. The sliding block 205 synchronously drives the fixed rod 207, the connecting block 206 and the welding head 209 to move until the nozzle of the welding head 209 is aligned with the starting position of the weld. This can be precisely controlled through the "fine adjustment" function of the control panel 203. After the alignment is completed, the position of the hydraulic telescopic rod 204 is locked through the control panel 203 to prevent height deviation during the welding process.

[0028] Click the "Start Welding" button on the control panel 203. The welding head 209 will begin preheating according to the preset parameters, which will be adjusted according to the thickness of the plate. After preheating, the arc and welding wire will be automatically output. If it is gas metal arc welding, the "automatic lifting" function will be activated. The hydraulic telescopic rod 204 will drive the welding head 209 to rise or fall at a uniform speed along the weld seam according to the preset speed. The industrial camera 208 will capture the welding area in real time. The molten pool shape, welding wire feeding position and weld formation can be clearly observed in the picture. If the weld seam deviates during the welding process, such as the molten pool deviating from the weld seam centerline in the camera picture, the operator can adjust the lifting direction of the hydraulic telescopic rod 204 by making a lateral fine adjustment through the "emergency fine adjustment" button on the control panel 203, or pause welding and move the device slightly to ensure that the weld seam is continuous and uniform. When the welding head 209 reaches the top or bottom of the weld seam, the control panel 203 will automatically trigger the "arc termination program". The welding head 209 will gradually reduce the current and voltage to complete the crater filling and avoid crater cracks. Then the welding will automatically stop.
