Description

A device for assembling and welding steel plates for lining a high-level water tank Technical Field

[0001] This utility model belongs to the field of steel plate welding technology, specifically a device for assembling and welding steel plates for the inner lining of a high-level water tank. Background Technology

[0002] Elevated water tanks are water storage structures built on high ground. They are commonly circular or rectangular in shape and are mainly constructed of reinforced concrete, making them sturdy and leak-proof.

[0003] When constructing elevated water tanks, the tank structure is typically reinforced with inner steel plates to improve structural stability and effectively prevent water from seeping out of the tank walls or bottom, ensuring normal use of the tank, reducing water waste, and lowering maintenance costs. During the construction of the inner lining of elevated water tanks, multiple steel plates need to be assembled and welded. However, the initial assembly gap between two steel plates is not easy to adjust and limit during assembly and welding. If the assembly gap is too large or too small, it will have a certain impact on the welding quality.

[0004] Therefore, this utility model provides a device for assembling and welding steel plates for the inner lining of a high-level water tank. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A high-level water tank lining steel plate assembly and welding device of this utility model includes connecting blocks; multiple connecting blocks are provided and divided into two groups; multiple suction cups are fixedly connected to the bottom of each connecting block; a connecting rod is fixedly connected between each group of connecting blocks; a connecting bolt is detachably installed in the middle of each connecting rod; a pair of connecting pipes are installed between a pair of connecting rods; a connecting rod is installed between a pair of connecting pipes; the connecting pipes and the connecting bolts are threadedly connected; through the above structure, the initial assembly gap at the start of welding can be conveniently adjusted and controlled when welding the high-level water tank lining steel plate, thereby improving the convenience and quality of welding.

[0007] Preferably, the connecting block has multiple cavities in its center; each cavity communicates with the inside of the suction cup; a piston is slidably connected to the center of each cavity; a movable rod is fixedly connected to the top of the piston; a fixed rod is fixedly connected to the top of each movable rod; an adjusting bolt is threadedly connected to the center of the fixed rod; the bottom end of the adjusting bolt is rotatably connected to the top of the connecting block; through the above structure, the adsorption force between the device and the steel plate can be increased, thereby increasing the friction between the two, reducing the occurrence of insufficient limiting effect caused by a large and heavy steel plate, and improving the use effect of the device.

[0008] Preferably, a pair of guide rods are slidably connected to the middle of the connecting rod; a spring is installed in the middle of the guide rod; a pressure plate is fixedly connected to the bottom of the pair of guide rods; a rubber pad is fixedly connected to the bottom of the pressure plate; with the above structure, the friction between the device and the steel plate can be increased after the device is installed, thereby further reducing the occurrence of relative sliding between the device and the steel plate, which would lead to a decrease in the limiting effect on the steel plate.

[0010] Preferably, a limiting plate is fixedly connected to the middle of the connecting pipe; the connecting rod is U-shaped and rotatably connected between a pair of connecting pipes; with the above structure, the position of the connecting rod can be adjusted when welding the steel plate, reducing the obstruction caused by the connecting rod to the welding of the steel plate and improving the ease of use of the device.

[0011] Preferably, a pair of first magnets are fixed to the middle of the connecting rod; there is a gap between the pair of first magnets; with the above structure, when the connecting rod is rotated to the top, it is difficult for the connecting rod to fall due to its own weight, further reducing the impact on the welding work and improving the ease of use of the device.

[0012] Preferably, a plurality of second magnets are fixedly connected to the top of the pressure plate; through the above structure, the squeezing force of the pressure plate on the side wall of the steel plate can be increased, thereby further increasing the friction between the rubber pad and the steel plate, and further reducing the occurrence of relative sliding between the steel plate and the device, which leads to a decrease in the limiting effect.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As shown in Figures 1 to 4, an embodiment of the present invention provides a steel plate assembly and welding device for a high-level water tank lining, comprising connecting blocks 1; multiple connecting blocks 1 are provided and divided into two groups; multiple suction cups 12 are fixedly connected to the bottom of the connecting blocks 1; connecting rods 13 are fixedly connected between each group of connecting blocks 1; connecting bolts 14 are detachably installed in the middle of the connecting rods 13; a pair of connecting pipes 15 are installed between a pair of connecting rods 13; a connecting rod 16 is installed between a pair of connecting pipes 15; the connecting pipes 15 and the connecting bolts 14 are threadedly connected; during operation, after bringing the edges of a pair of steel plates to be welded together, the two groups of connecting blocks 1 are respectively connected by the suction cups 12. The suction cups adhere to the surfaces of two steel plates, and then a pair of connecting tubes 15 are placed between a pair of connecting rods 13. A connecting bolt 14 is then passed through the middle of the connecting rod 13 and screwed into the connecting tube 15. By continuously tightening the connecting bolt 14, the pair of connecting rods 13 are subjected to force and brought closer together. Then, multiple suction cups 12 apply a force to bring the pair of steel plates closer together, so that the assembly gap between the pair of steel plates maintains a suitable initial welding width. With the above structure, when welding the inner lining steel plates of the high-level water tank, the initial assembly gap at the start of welding can be easily adjusted and controlled, thereby improving the convenience and quality of welding.

[0024] As shown in Figures 1 to 4, the connecting block 1 has multiple cavities 2 in its middle; the cavities 2 are connected to the inside of the suction cups 12; a piston 21 is slidably connected to the middle of the cavity 2; a movable rod 22 is fixedly connected to the top of the piston 21; a fixed rod 23 is fixedly connected to the top of the multiple movable rods 22; an adjusting bolt 24 is threadedly connected to the middle of the fixed rod 23; the bottom end of the adjusting bolt 24 is rotatably connected to the top of the connecting block 1; during operation, after the multiple suction cups 12 are attached to the surface of the steel plate, the adjusting bolt 24 can be rotated to move the fixed rod 23, thereby moving the multiple movable rods 22 through the fixed rod 23, causing the multiple pistons 21 to rise. The rise of the pistons 21 increases the space at the bottom of the pistons 21 and increases the negative pressure intensity, increasing the adsorption force between the suction cups 12 and the side wall of the steel plate. Through the above structure, the adsorption force between the device and the steel plate can be improved, thereby increasing the friction between the two, reducing the occurrence of insufficient limiting effect caused by the large and heavy steel plate, and improving the use effect of the device.

[0025] As shown in Figures 1 and 2, a pair of guide rods 3 are slidably connected to the middle of the connecting rod 13; a spring 31 is installed in the middle of the guide rod 3; a pressure plate 32 is fixedly connected to the bottom of the pair of guide rods 3; a rubber pad 33 is fixedly connected to the bottom of the pressure plate 32; during operation, after the device is installed on the side wall of the steel plate, the pressure plate 32 will be pressed against the side wall of the steel plate under the elastic force of the pair of springs 31, so that the rubber pad 33 is tightly attached to the side wall of the steel plate, and a certain frictional force is generated between the rubber pad 33 and the side wall of the steel plate. Through the above structure, the frictional force between the device and the steel plate can be increased after the device is installed, thereby further reducing the occurrence of relative sliding between the device and the steel plate, which leads to a decrease in the limiting effect on the steel plate.

[0026] As shown in Figures 1 to 4, a collar 4 is rotatably connected to the middle of the adjusting bolt 24; a limiting rod 41 is fixedly connected to the bottom of the collar 4; the bottom end of the limiting rod 41 is fixedly connected to the top of the connecting block 1; a fixing rod 23 is slidably connected to the middle of the limiting rod 41; elastic membrane sleeves 42 are fixedly connected to both the top and bottom of the fixing rod 23; the other ends of a pair of elastic membrane sleeves 42 are respectively fixed to the bottom of the collar 4 and the top of the connecting block 1; the elastic membrane sleeves 42 surround the adjusting bolt 24 internally; during operation, some debris will splash when welding the steel plate. When the debris falls on the thread in the middle of the adjusting bolt 24, it will affect the subsequent rotation adjustment of the adjusting bolt 24. By setting the elastic membrane sleeves 42, the splashed debris will be blocked by the elastic membrane sleeves 42 and will be difficult to fall on the middle of the adjusting bolt 24, thereby reducing the obstruction caused by debris adhering to the middle of the adjusting bolt 24 when adjusting the position of multiple pistons 21 by rotating the adjusting bolt 24.

[0027] As shown in Figure 1, a limiting plate 5 is fixedly connected to the middle of the connecting pipe 15; the connecting rod 16 is U-shaped and rotatably connected between a pair of connecting pipes 15; during operation, after the two sets of connecting blocks 1 are adsorbed onto a pair of steel plates by the suction cup 12, the connecting rod 16 will be positioned between the pair of steel plates. When welding is required at the gap of the connecting rod 16, the connecting rod 16 can be rotated to move it to another location, reducing the obstruction to welding. The setting of the limiting plate 5 makes it difficult for the connecting pipe 15 to rotate relative to the steel plate, thereby reducing the situation where the connecting rod 16 drives the connecting pipe 15 to rotate, which reduces the limiting effect of the device on the steel plate. With the above structure, the position of the connecting rod 16 can be adjusted when welding the steel plate, reducing the obstruction caused by the connecting rod 16 to the welding of the steel plate and improving the ease of use of the device.

[0028] As shown in Figure 1, a pair of first magnets 6 are fixed to the middle of the connecting rod 16; there is a gap between the pair of first magnets 6; after the connecting rod 16 is rotated from the bottom to the top, the first magnets 6 will be attracted to the steel plate, making it difficult for the connecting rod 16 to rotate and fall. With the above structure, when the connecting rod 16 is rotated to the top, it is difficult for the connecting rod 16 to fall due to its own weight, further reducing the impact on the welding work and improving the ease of use of the device.

[0029] As shown in Figure 2, multiple second magnets 7 are fixed to the top of the pressure plate 32. Through the above structure, the squeezing force of the pressure plate 32 on the side wall of the steel plate can be increased, thereby further increasing the friction between the rubber pad 33 and the steel plate, and further reducing the occurrence of relative sliding between the steel plate and the device, which leads to a decrease in the limiting effect.

[0030] During operation, after bringing the edges of a pair of steel plates to be welded together, two sets of connecting blocks 1 are respectively attached to the surfaces of the two steel plates using suction cups 12. Then, a pair of connecting tubes 15 are placed between a pair of connecting rods 13. A connecting bolt 14 is then passed through the middle of the connecting rod 13 and screwed into the connecting tube 15. By continuously tightening the connecting bolt 14, the pair of connecting rods 13 are subjected to force and brought closer together. Subsequently, multiple suction cups 12 apply a force to bring the pair of steel plates closer together, maintaining a proper assembly gap between the pair of steel plates. With an appropriate initial welding width, after attaching multiple suction cups 12 to the surface of the steel plate, the adjusting bolt 24 can be rotated to move the fixing rod 23, which in turn moves multiple movable rods 22, causing multiple pistons 21 to rise. The rise of the pistons 21 increases the space at their bottom and enhances the negative pressure, increasing the adhesion between the suction cups 12 and the sidewall of the steel plate. After the device is installed on the sidewall of the steel plate, the pressure plate 32 is pressed against the sidewall of the steel plate by the elastic force of a pair of springs 31, thus tightening the rubber pad 33. The rubber pad 33 is attached to the side wall of the steel plate, creating friction between it and the side wall. During welding, some debris will fly off. When this debris lands on the threaded part of the adjusting bolt 24, it can affect subsequent rotation. The elastic diaphragm sleeve 42 prevents the flying debris from landing on the center of the adjusting bolt 24. After the two sets of connecting blocks 1 are attached to a pair of steel plates using the suction cup 12, the connecting rod 16 will be positioned between the two steel plates. When welding the gap at the connecting rod 16, the connecting rod 16 can be rotated to move it to another location, reducing the obstruction to the welding. The setting of the limiting plate 5 makes it difficult for the connecting tube 15 to rotate relative to the steel plate. Thus, when the connecting rod 16 is rotated, the situation where the connecting rod 16 drives the connecting tube 15 to rotate and the limiting effect of the device on the steel plate decreases is reduced. After the connecting rod 16 is rotated from the bottom to the top, the first magnet 6 will be attracted to the steel plate, making it difficult for the connecting rod 16 to rotate and fall.
