Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically to a segmented automatic welding equipment for on-site connection of ground screws. Background Technology

[0002] In the field of foundation construction for photovoltaics, fences, and wooden houses, ground bolts, as shallow foundation bearing components, are often insufficient in length due to the influence of site foundation depth and construction design parameters. It is necessary to weld the extended sections to the foundation ground bolts on site to extend the overall length into the ground to meet the foundation bearing capacity requirements. Ground bolt on-site welding equipment, as a supporting welding tool for outdoor construction, is widely used in outdoor photovoltaic power stations, garden fences, light housing construction and other outdoor foundation construction sites.

[0003] Existing automatic welding equipment for ground screws typically employs a structure with a closed welding chamber and short-distance clamping seats at both ends. It mainly consists of the equipment body, the closed welding chamber, clamping blocks at both ends, and an internal welding mechanism. During operation, the main body of the ground screw to be connected and the two ends of the extended section are inserted into the closed chamber. The clamping blocks on both sides of the chamber clamp the pipe ends, and after closing the chamber door, the welding mechanism is activated to complete the fusion welding operation on the circumferential seam. This equipment can complete the butt welding operation of basic pipes and has applications in pipe welding scenarios.

[0004] However, existing equipment typically clamps the ground bolts in narrow areas at both ends. For long ground bolt extensions, the clamping support spacing is short, and there is a lack of auxiliary support points in the middle of the extension. The pipe is prone to shaking and shifting when suspended. At the same time, during the processing and transportation of ground bolts, impurities such as mud, sand, and rust debris will adhere to the outer wall of the butt weld. The impurities left around the weld will significantly reduce the welding effect, making it difficult to meet the requirements of stable and high-quality welding construction for on-site extension of ground bolts. Therefore, further improvements are needed. Summary of the Invention

A bevel gear set is provided between the first transmission rod and the spiral rod. A fastening bolt is threaded on the surface of the main body of the equipment, and the end of the fastening bolt abuts against the outer wall of the spiral rod for locking the clamping assembly.

[0010] Preferably, the cleaning mechanism includes a drive gear ring rotatably installed inside the main body of the equipment, and a sliding block is slidably installed on the outer wall of the drive gear ring. An installation rod is slidably installed at the end of the sliding block, and a cleaning head is provided at the end of the installation rod away from the sliding block. The installation rod is Z-shaped in general. A planetary gear set is provided inside the main body of the equipment, and the planetary gear set is meshed with the drive gear ring.

[0011] Preferably, the end of the cleaning head contacts the outer wall of the welded seam of the ground screw, the bottom of the spiral sleeve is rotatably mounted with a driving bevel gear, and the driving bevel gear is slidably connected to the spiral rod. The main body of the equipment is provided with a second transmission rod, and one end of the second transmission rod is provided with a driven bevel gear, and the driven bevel gear is meshed with the driving bevel gear. A bevel gear set is provided between the second transmission rod and the planetary gear set.

[0012] Preferably, the main body of the equipment is provided with a reset assembly to prevent the cleaning mechanism from obstructing the welding operation. The reset assembly includes a reset groove formed on the outer wall of the mounting rod, and the inner wall of the sliding block is provided with a reset protrusion adapted to the reset groove. A reset spring is sleeved on the outer wall of the mounting rod.

The entire clamping support, circumferential seam cleaning, and avoidance protection structure share a single screw rod transmission source, eliminating the need for separate drive components. It is suitable for various outdoor construction sites such as photovoltaic and wooden houses, reducing tooling transportation costs and extending the service life of each transmission component of the equipment.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-8 The present invention provides the following technical solution: a segmented automatic welding device for on-site mating of ground screws, comprising a device body 1, a welding cavity 101 inside the device body 1, and an automatic welding mechanism 102 installed inside the welding cavity 101; a support mechanism for auxiliary support of the extended section of the ground screw is provided on the surface of the device body 1, the support mechanism includes a lifting frame 2 slidably installed on the surface of the device body 1, a spiral rod 4 is installed at the bottom of the lifting frame 2 through a bearing, a clamping component for clamping the extended section of the ground screw is provided at the end of the lifting frame 2, and a cleaning mechanism for cleaning the outer wall of the mating seam of the ground screw is provided inside the device body 1.

[0021] In one embodiment of the present invention, a spiral sleeve 401 is fixedly installed inside the main body 1 of the device, and the spiral rod 4 is threadedly connected to the spiral sleeve 401, and the spiral rod 4 is arranged perpendicular to the device. Place the entire machine above the foundation screws, adjust the position of the main body 1 of the equipment so that the center of the welding cavity 101 is aligned with the circumferential seam of the foundation screws. At this time, the lifting frame 2 is in the lowest storage position, and the segmented extended section can be sent into the welding cavity 101 to complete the initial alignment.

[0022] In one embodiment of the present invention, the clamping assembly includes a clamping block 3 slidably mounted on the end of the lifting frame 2, and a clamping roller 301 is rotatably mounted on the outer wall of the clamping block 3. A bidirectional lead screw 302 is rotatably mounted inside the lifting frame 2, and the bidirectional lead screw 302 is threadedly connected to the clamping block 3. A first transmission rod 402 is provided inside the lifting frame 2, and a helical gear set is provided between the first transmission rod 402 and the bidirectional lead screw 302. As one embodiment of the present invention, two sets of clamping blocks 3 are symmetrically arranged, and clamping rollers 301 are symmetrically arranged on the outer wall of the clamping blocks 3. After the two sets of clamping blocks 3 are closed, the whole structure is V-shaped, and the outer wall of the clamping rollers 301 is in contact with the outer wall of the extended section of the ground screw. A bevel gear set is assembled between the first transmission rod 402 and the spiral rod 4. A fastening bolt 5 is threaded on the surface of the main body 1 of the equipment. The fastening end is pressed against the outer wall of the spiral rod 4 to lock the position of the lifting frame 2. The operator pulls the lifting frame 2 upwards, and the lifting frame 2 slides upwards along the vertical track on the outer wall of the equipment. The screw rod 4 moves upwards in a straight line synchronously with the lifting frame 2. The screw rod 4 rotates due to the threaded engagement between the screw rod 4 and the screw sleeve 401. The bevel gear at the bottom of the screw rod 4 synchronously drives the first transmission rod 402 to rotate. The first transmission rod 402 drives the double-sided lead screw 302 to rotate via the helical gear set. The double-sided lead screw 302 drives the clamping blocks 3 on both sides to slide synchronously towards each other. The clamping rollers 301 fit against the outer wall of the extended section to form multi-point circumferential support, preventing the extended section from shifting or shaking.

[0023] As one embodiment of the present invention, the cleaning mechanism includes a drive gear ring 6 rotatably installed inside the equipment body 1, and a sliding block 602 is slidably assembled on the outer wall of the drive gear ring 6. An installation rod 603 is fixedly installed at the end of the sliding block 602. The overall installation has a Z-shaped structure. A planetary gear set 601 is provided inside the equipment body 1. The planetary gear set 601 meshes with the drive gear ring 6 for transmission. In one embodiment of the present invention, the cleaning head 604 is fixedly installed on the end of the mounting rod 603 away from the sliding block 602. The end face of the cleaning head 604 is in contact with the outer wall of the butt weld of the ground screw. The bottom end of the spiral sleeve 401 is rotatably equipped with the driving bevel gear 403. The driving bevel gear 403 is slidably connected with the spiral rod 4. The second transmission rod 404 is rotatably installed inside the equipment. The two ends of the second transmission rod 404 are respectively equipped with the driven cone and the planetary bevel gear. The driven cone meshes with the driving cone. During the rotation of the spiral rod 4, the bottom active cone rotates synchronously, meshing with the driven cone to drive the second transmission. The second transmission rod 404 drives the planetary gear set 601 through the bevel gear set. The planetary gear set 601 drives the drive gear ring 6 to rotate around. The drive gear ring 6 drives the sliding block 602, Z-shaped mounting rod 603, and cleaning head 604 to grind along the circumference of the butt weld to remove mud, sand, and impurities from the weld surface.

[0024] As one embodiment of the present invention, the device body 1 is provided with a reset assembly. The reset assembly includes a reset groove 701 formed on the outer wall of the mounting rod 603, a reset protrusion 7 adapted to the reset groove 701 fixedly installed on the inner wall of the sliding block 602, a reset spring 702 sleeved on the outer wall of the mounting rod 603, and a reset rod 8 slidably installed inside the device body 1. One end of the reset rod 8 abuts against the end of the mounting rod 603, and the other end of the reset rod 8 is threadedly connected to the fastening bolt 5. As one embodiment of the present invention, multiple sets of limiting protrusions 9 are fixedly installed on the inner wall of the welding cavity 101. The limiting protrusions 9 are distributed at equal angles along the circumference of the welding cavity 101, and the upper and lower layers of limiting protrusions are staggered. The inner wall of the limiting protrusions 9 is in contact with the rod body of the mounting rod 603. As the drive gear ring 6 rotates the mounting rod 603, the rod body continuously and alternately abuts against the staggered limiting protrusions 9, forcing the mounting rod 603 to move the cleaning head 604 slightly up and down, achieving full-circumference grinding of the weld seam without dead angles; when the fastening bolt 5 is tightened upwards, the fastening bolt 5 pulls the reset rod 8 into the welding cavity 101, the reset rod 8 presses against the end of the mounting rod 603, the reset protrusion 7 slides along the reset slide groove 701, the mounting rod 603 compresses the reset spring 702 and simultaneously undergoes circumferential deflection, shifting the cleaning to the outside of the welding needle's travel trajectory, completely avoiding the welding area, and preventing the welding needle from scraping and interfering with the cleaning head 604; when the fastening bolt 5 is tightened inwards, the lifting frame 2 and the spiral rod 4 are locked, the support clamping structure remains in a state of holding the extended section, the cleaning mechanism simultaneously avoids the welding station, at this time the built-in automatic welding mechanism 102 of the equipment is activated, and the welding needle rotates at a uniform speed along the butt joint to complete the argon arc automatic welding; After the single-bolt extension section is welded, the outer fastener 5 is loosened in the reverse direction. The reset rod 8 releases the pushing constraint on the mounting rod 603. The reset spring 702 pushes the mounting rod 603 to rotate and reset. The cleaning head 604 returns to the corresponding position of the weld. The lifting frame 2 is released downwards. The spiral rod 4 rotates in the reverse direction. The bidirectional screw 302 drives the clamping blocks 3 on both sides to separate and release the extension section. The planetary gear set 601 and the drive gear ring 6 rotate in the reverse direction synchronously. All support and cleaning components are automatically stored and reset. The single segmented butt welding operation can be completed by opening the welding cavity 101 shell.

[0025] Working Principle: When the segmented automatic welding equipment for on-site bolt connection is working, the entire machine is first placed on top of the foundation bolt that has been driven into the soil. The position of the equipment is adjusted so that the welding needle of the automatic welding mechanism 102 inside the welding chamber 101 is aligned with the butt weld between the foundation bolt and the extended section. The equipment shell is closed to complete the cavity sealing and locking. The foundation clamping structure inside the shell first provides initial limit to both ends of the bolt. Then, the operator manually lifts the lifting frame 2 upwards. The lifting frame 2 slides upwards along the vertical track on the outer wall of the main body 1. The bottom of the lifting frame 2 is equipped with a screw rod 4, which rises with the frame. The screw rod 4 engages with the screw sleeve 401 inside the equipment, and the linear motion of lifting is converted into the rotation of the screw rod 4. The screw rod 4 synchronously drives two transmission structures to operate synchronously. The upper end of one screw rod 4 transmits the first transmission rod 402 through a bevel gear set. The first transmission rod 402 transmits the torque to the bidirectional lead screw 302 inside the lifting frame 2. 02 The forward rotation drives two sets of symmetrical clamping blocks 3 to move closer together. The clamping rollers 301 on the outer side of the clamping blocks 3 fit against the outer wall of the extended section, forming multi-point auxiliary support to prevent the extended section from shifting. The active bevel gear 403 at the bottom of the second spiral rod 4 rotates synchronously with the rod body and meshes with the driven bevel gear 405 at the end of the second transmission rod 404. The second transmission rod 404 transmits power to the planetary gear set 601. The planetary gear set 601 meshes and drives the gear ring 6 to rotate in a circle. The sliding block 602 on the outer wall of the gear ring 6 drives the Z-shaped mounting rod 603 and the front cleaning head 604 to rotate around the butt weld. The cleaning head 604 fits against the outer wall of the weld to grind and remove surface mud and impurities. The inner wall of the welding cavity 101 is arranged with staggered limit protrusions 9 at equal angles. During the rotation of the mounting rod 603, the rod body continuously and alternately abuts against the limit protrusions 9, forcing the mounting rod 603 to drive the cleaning head 604 to float up and down slightly, so as to achieve grinding and cleaning of the weld without dead angles. As the lifting frame 2 continues to rise until the clamping roller 301 fully grips the extended section and the lifting stroke reaches its upper limit, the extended section completes its multi-point support positioning. Simultaneously, the drive gear ring 6 drives the cleaning head 604 to automatically rotate and reset to its initial standby position. The operator rotates the outer fastening bolt 5 inwards, causing the end of the fastening bolt 5 to press against the outer wall of the spiral rod 4, locking the spiral rod 4 and the lifting frame 2 together to prevent the support mechanism from slipping under pressure. During the inward rotation of the fastening bolt 5, the threaded engagement pulls the reset rod 8 to slide outwards from the equipment. As the reset rod 8 moves, the end of the reset rod 8 disengages from the end limit constraint of the Z-shaped mounting rod 603. The reset spring 702 on the outer wall of the mounting rod 603 releases its elastic force, pushing the rod body outward. At the same time, the reset groove 701 on the outer wall of the mounting rod 603 slides relative to the reset protrusion 7 inside the sliding block 602. The Z-shaped mounting assembly rotates 90° circumferentially under the guidance of the inclined surface of the groove, causing the front cleaning head 604 to shift to the outside of the horizontal plane of the welding needle. The cleaning assembly completely avoids the welding trajectory, preventing the cleaning head 604 from interfering with or rubbing against the welding needle and molten pool during subsequent welding. After the cleaning components complete the avoidance, the built-in automatic welding mechanism 102 of the equipment is activated. The equipment adopts a track-type pipe-to-pipe TIG circumferential welding structure. The digital welding power supply is pre-loaded with the corresponding steel welding process parameters. The tungsten electrode of the welding needle is aligned with the butt weld and a stable arc is ignited. The welding drive track drives the welding needle to move around the 360° circumferential weld at a uniform speed. The molten pool shape is stably controlled throughout the process to complete the automatic welding. The automatic welding mechanism 102 is a conventional technical structure known in the field. Its specific composition, assembly relationship and working principle are all within the scope of existing technology and will not be described in detail here. After the complete circumferential welding process is completed, the operator loosens the outer fastener 5 by rotating it in the opposite direction. The fastener 5 disengages from the outer wall of the spiral rod 4 and unlocks the support mechanism. At the same time, the reset rod 8 pushes the Z-shaped mounting rod 603 into the equipment through the threaded transmission, compressing the reset spring 702. The reset protrusion 7 slides along the reset groove 701, causing the installation to rotate 90° in the opposite direction. The cleaning head 604 returns to the corresponding position of the weld. The external force pulling the lifting frame 2 upward is released, and the lifting frame 2 slides down the track. The spiral rod 4 rotates in the opposite direction, and the bidirectional screw 302 reverses to separate the clamping blocks 3 on both sides and release the extended section. The planetary gear set 601 and the drive gear ring 6 rotate in the opposite direction synchronously. All support and cleaning transmission mechanisms are reset and stored. The equipment shell is opened to take out the welded integrated floor screw, completing the entire process of single-segment butt welding. The complete set of segmented automatic welding equipment for on-site ground bolt connection relies on a single lifting and pulling action to simultaneously complete the middle support of the pipe and the pre-weld cleaning. The locking operation linkage cleaning component automatically avoids the welding area. There is no need to provide large clamping tools for field construction. It simultaneously solves the pain points of extended section offset and weld impurities, and improves the efficiency of outdoor ground bolt extension connection construction.
