Benefits of technology

[0014] 1. This utility model, by setting up a drive motor, a double-threaded screw, a rotating rod, a lifting plate, and clamping plates, allows the double-threaded screw to rotate during operation, causing the two T-shaped plates to move towards each other. This, in turn, causes the two rotating rods to rotate, moving the lifting plate upward. Consequently, the two L-shaped plates retract into the interior of the lifting plate and move the two clamping plates upward to clamp, fix, and precisely position the spiral blades. This facilitates the operator in initially welding the spiral blades onto the outer surface of the ground pile. After the spiral blades are initially welded and fixed, the drive motor is restarted, and the double-threaded screw rotates again, causing the two T-shaped plates to move away from each other. This, in turn, causes the two rotating rods to rotate, pulling the lifting plate downward. This allows the two L-shaped plates to extend to the outside of the lifting plate and move the two clamping plates downward, thus not hindering the subsequent welding of the spiral blades.

Description

Technical Field

[0001] This utility model belongs to the technical field of welding auxiliary equipment, specifically a welding auxiliary device for the spiral blades of a spiral ground pile. Background Technology

[0002] Helical piles are prefabricated foundation components used in construction, photovoltaics, municipal engineering, and other fields. They mainly consist of a central metal rod and helical blades welded to the rod. They are screwed into the soil using specialized equipment to provide support and fixation for the superstructure.

[0003] When welding the helical blades of helical piles, welding auxiliary devices are often used. While existing welding auxiliary devices can provide basic support and fixation for the helical piles, they lack the function of fixing and positioning the helical blades. This forces operators to manually fix the helical blades to prevent them from moving during welding, and only after the initial welding of the blades can they be loosened before the full welding is completed. This method not only easily leads to inaccurate positioning of the helical blades but also increases the workload of the operators. Therefore, improvements are needed. Utility Model Content

[0006] As a preferred embodiment of this utility model, a fixing block is movably sleeved on the outer surface of the left side of the double threaded screw, and the top of the fixing block is fixedly connected to the top of the inner cavity of the base.

[0007] As a preferred technical solution of this utility model, the top of the inner cavity of the base is fixedly connected with a limiting rod, and there are two limiting rods. The outer surfaces of the two limiting rods are movably sleeved with the inner surface of the T-shaped plate.

[0008] As a preferred embodiment of this utility model, a mounting plate is fixedly connected to the right side of the top of the base, a circular block is movably sleeved inside the mounting plate, a disc is fixedly connected to the left side of the circular block, and the right side of the disc is movably connected to the outer surface of the mounting plate.

[0009] As a preferred embodiment of this utility model, a fixing clamp is fixedly connected to the outer surface of the disc, and a rectangular plate located directly above the fixing clamp is fixedly connected to the outer surface of the disc. A threaded rod is threadedly connected to the inside of the rectangular plate, and a movable clamp is movably sleeved on the outer surface of the threaded rod. The right side of the movable clamp is movably connected to the outer side of the disc.

[0010] As a preferred embodiment of this utility model, the inside of the disc is provided with a sliding groove, and a limiting block is movably connected to the inner surface of the sliding groove. The left side of the limiting block is fixedly connected to the outer surface of the movable clamp.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up a drive motor, a double-threaded screw, a rotating rod, a lifting plate, and clamping plates, allows the double-threaded screw to rotate during operation, causing the two T-shaped plates to move towards each other. This, in turn, causes the two rotating rods to rotate, moving the lifting plate upward. Consequently, the two L-shaped plates retract into the interior of the lifting plate and move the two clamping plates upward to clamp, fix, and precisely position the spiral blades. This facilitates the operator in initially welding the spiral blades onto the outer surface of the ground pile. After the spiral blades are initially welded and fixed, the drive motor is restarted, and the double-threaded screw rotates again, causing the two T-shaped plates to move away from each other. This, in turn, causes the two rotating rods to rotate, pulling the lifting plate downward. This allows the two L-shaped plates to extend to the outside of the lifting plate and move the two clamping plates downward, thus not hindering the subsequent welding of the spiral blades.

[0015] 2. This utility model, by setting up a disc, a transmission motor, a gear, and a gear ring, will cause the transmission shaft to drive the gear to rotate when the transmission motor is running. This will cause the gear and gear ring to mesh and drive the disc to rotate slowly, thereby driving the ground pile and the spiral blade to rotate slowly. This makes it convenient for operators to weld along the spiral edge of the spiral blade, thus improving the convenience of the device. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 6As shown, this utility model provides a welding auxiliary device for the spiral blades of a spiral ground pile, including a base 1, a support plate 2 fixedly connected to the left side of the top of the base 1, a ground pile 3 movably connected to the outer surface of the top of the support plate 2, a spiral blade 4 movably sleeved on the outer surface of the ground pile 3, a drive motor 5 fixedly connected to the top of the inner cavity of the base 1, a double threaded screw 6 fixedly sleeved at the other end of the output shaft of the drive motor 5, a T-shaped plate 7 threadedly sleeved on the outer surface of the double threaded screw 6, two T-shaped plates 7, the outer surfaces of the two T-shaped plates 7 are movably connected to the inner surface of the top of the base 1, a rotating rod 8 is hinged to the inner side of the two T-shaped plates 7, a lifting plate 9 is hinged to the other end of the rotating rod 8, an L-shaped plate 10 is movably sleeved inside the lifting plate 9, a clamping plate 11 is fixedly connected to the outer side of the L-shaped plate 10, and the outer surface of the clamping plate 11 is movably sleeved with the inner surface of the T-shaped plate 7.

[0025] When the drive motor 5 is running, it will drive the double threaded screw 6 to rotate, which in turn drives the two T-shaped plates 7 to move towards each other. This process causes the two rotating rods 8 to rotate accordingly, driving the lifting plate 9 to move upward, thereby causing the two L-shaped plates 10 to retract into the lifting plate 9, and driving the two clamping plates 11 to move upward, realizing the clamping, fixing and precise positioning of the spiral blade 4. In this way, the operator can easily weld the spiral blade 4 to the outer surface of the ground pile 3. After the spiral blade 4 is initially fixed, the drive motor 5 is started again, and the double threaded screw 6 will rotate again, driving the two T-shaped plates 7 to move away from each other. At this time, the two rotating rods 8 rotate and pull the lifting plate 9 downward, causing the two L-shaped plates 10 to extend to the outside of the lifting plate 9, and driving the two clamping plates 11 to move downward, so as not to hinder the subsequent welding work of the spiral blade 4.

[0026] Among them, a fixing block 12 is movably sleeved on the outer surface of the left side of the double threaded screw 6, and the top of the fixing block 12 is fixedly connected to the top of the inner cavity of the base 1.

[0027] The design of the fixing block 12 serves to support the double threaded screw 6 and ensure the stability of the double threaded screw 6 during rotation.

[0028] Among them, the top of the inner cavity of the base 1 is fixedly connected with a limiting rod 13. There are two limiting rods 13, and the outer surfaces of the two limiting rods 13 are movably sleeved with the inner surface of the T-shaped plate 7.

[0029] The design of the two limit rods 13 serves to limit the movement of the two T-shaped plates 7, ensuring the stability of the horizontal movement of the T-shaped plates 7.

[0030] The base 1 has a mounting plate 14 fixedly connected to the right side of its top. A ring block 15 is movably fitted inside the mounting plate 14. A disc 16 is fixedly connected to the left side of the ring block 15. The right side of the disc 16 is movably connected to the outer surface of the mounting plate 14.

[0031] This design allows the disc 16 and the ring block 15 to rotate around the center of the mounting plate 14.

[0032] The outer surface of the disc 16 is fixedly connected to a fixing clamp 17, and the outer surface of the disc 16 is fixedly connected to a rectangular plate 18 located directly above the fixing clamp 17. The rectangular plate 18 is internally threaded with a threaded rod 19, and the outer surface of the threaded rod 19 is movably sleeved with a movable clamp 20. The right side of the movable clamp 20 is movably connected to the outer side of the disc 16.

[0033] The downward movement of the rotating threaded rod 19 will cause the movable clamp 20 to move downward. With the cooperation of the fixed clamp 17 and the movable clamp 20, the purpose of clamping and fixing the ground pile 3 is achieved.

[0034] The disc 16 has a groove 21 inside, and a limit block 22 is movably connected to the inner surface of the groove 21. The left side of the limit block 22 is fixedly connected to the outer surface of the movable clamp 20.

[0035] The design of the slide 21 and the limiting block 22 serves to limit the movement of the movable clamp 20, enabling the movable clamp 20 to move downward stably.

[0036] The base 1 is fixedly connected to a drive motor 23 located behind the mounting plate 14. The other end of the output shaft of the drive motor 23 is fixedly sleeved with a drive shaft 24. A gear 25 is fixedly sleeved on the outer surface of the drive shaft 24. A gear ring 26 is meshed on the outer surface of the gear 25. The inner surface of the gear ring 26 is fixedly sleeved with the outer surface of the disc 16.

[0037] When the drive motor 23 is running, the drive shaft 24 will drive the gear 25 to rotate, which in turn will cause the gear 25 to mesh with the gear ring 26 and drive the disk 16 to rotate slowly as a whole, thereby driving the ground pile 3 and the spiral blade 4 to rotate slowly, making it convenient for the operator to weld along the spiral edge of the spiral blade 4, thus improving the convenience of the device.

[0038] The base 1 has a round rod 27 fixedly connected to its top, and the outer surface of the round rod 27 is movably connected to the inner surface of the lifting plate 9.

[0039] The design of the round rod 27 serves to limit the lifting of the lifting plate 9, ensuring the stability of the lifting movement of the lifting plate 9.

[0040] Working principle and usage process of this utility model:

[0041] When the spiral blade 4 needs to be welded to the outer surface of the ground pile 3, first, the spiral blade 4 is sleeved onto the outer surface of the ground pile 3. Then, the ground pile 3 is placed above the support plate 2 and the fixing clamp 17. Subsequently, the threaded rod 19 is rotated downwards, which will drive the movable clamp 20 to move downwards to clamp and fix the ground pile 3. At this time, the drive motor 5 is started, which will cause the double threaded screw 6 to rotate, driving the two T-shaped plates 7 to move towards each other. This will cause the two rotating rods 8 to rotate, driving the lifting plate 9 to move upwards, thereby causing the two L-shaped plates 10 to retract into the lifting plate 9. The two clamping plates 11 move upward to clamp and fix the spiral blade 4, and accurately position it. This allows the operator to easily weld the spiral blade 4 onto the outer surface of the ground pile 3. After the spiral blade 4 is initially fixed, the drive motor 5 is started again. The double threaded screw 6 will rotate again and drive the two T-shaped plates 7 to move in opposite directions. This will cause the two rotating rods 8 to rotate and pull the lifting plate 9 downward. This will cause the two L-shaped plates 10 to extend to the outside of the lifting plate 9 and drive the two clamping plates 11 to move downward, thus not hindering the subsequent welding of the spiral blade 4.

[0042] When the drive motor 23 is started, the drive shaft 24 will drive the gear 25 to rotate, which will cause the gear 25 to mesh with the gear ring 26 and drive the disk 16 to rotate slowly as a whole. This will cause the ground pile 3 and the spiral blade 4 to rotate slowly, making it easier for the operator to weld along the spiral edge of the spiral blade 4, thus improving the convenience of the device.
