Among them, photovoltaic support products include photovoltaic spiral ground piles, photovoltaic prefabricated pipe piles, photovoltaic bored cast-in-place piles and photovoltaic cement ground piles. Among them, photovoltaic cement ground piles can bear the weight of photovoltaic brackets and photovoltaic panels, resist natural disasters such as strong winds and earthquakes, and ensure the safe and stable operation of photovoltaic power generation systems under various environmental conditions. Photovoltaic cement ground piles can be customized according to different geological conditions and project requirements. For example, in soft soil foundations, the pile length or pile diameter can be increased to increase the bearing capacity, and in rock foundations, special anchoring methods can be used for fixing. Figure 1 As shown, the photovoltaic cement ground pile has three steel bars 17 distributed in a triangle, and a plurality of triangular hoops 18 distributed at equal intervals are welded to the three steel bars 17. At the same time, a metal ground pile tube 16 is welded inside one end of the three steel bars 17.

[0003] At present, the production process of photovoltaic cement ground pile welding is mainly: placing steel bars and triangular hoops on the welding table, and multiple workers cooperate to position the triangular hoops and steel bars on the welding table one by one, and weld them one by one until a steel cage is welded; then the ground pile pipe is inserted into the three steel bars of the welded steel cage for a certain distance, and then the workers weld the section where the steel bars and the ground pile pipe are in contact, thus completing the production of photovoltaic cement ground piles.

[0004] The production process requires multiple workers to collaborate at the same time and to move materials multiple times, which is labor-intensive. Only one can be produced at a time, resulting in low production efficiency. The welding arc and smoke have a greater impact on the health of the workers, and the degree of automation is low. Summary of the invention

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0026] Various non-limiting embodiments of the present invention are described in detail below. Any number of elements in the accompanying drawings is for illustration and not for limitation, and any naming is only for distinction and does not have any limiting meaning. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0027] Example 1 like Figure 2 , Figure 3 As shown, a photovoltaic cement pile steel cage welding tool comprises a welding robot 4 and a welding positioning mechanism 1, wherein the welding positioning mechanism 1 has two welding positioning mechanisms 1 arranged at intervals, and the welding robot 4 is located between the two welding positioning mechanisms 1. The two welding positioning mechanisms 1 are symmetrically distributed on opposite sides of the welding robot 4.

[0028] The welding positioning mechanism 1 is used to place various components of the photovoltaic cement ground pile to be welded, including three steel bars 17, multiple triangular hoops 18 and a ground pile pipe 16, wherein the number of triangular hoops 18 can be determined according to the length of the steel bars 17, and the three steel bars 17 are arranged in a triangle. The welding robot 4 welds the multiple triangular hoops 18 to the three steel bars 17 at equal intervals, and then inserts one end of the ground pile pipe 16 into the three steel bars 17, and the steel bars 17 are located on the outside of the ground pile pipe 16. The welding robot 4 welds the ground pile pipe 16 and the three steel bars 17 together. In this embodiment, there are two welding positioning mechanisms 1 that are symmetrically distributed around the center. When the welding robot 4 welds the photovoltaic cement ground pile on one of the welding positioning mechanisms 1, the other welding positioning mechanism 1 is placed with the photovoltaic cement ground pile, so that the welding robot 4 alternates between the two welding positioning mechanisms 1 to perform welding operations, thereby improving the production efficiency of the welding operation.

[0029] In this embodiment, it is defined that the extending direction of the axis of the ground pile pipe 16 placed on the welding positioning mechanism 1 is the left-right direction.

[0030] In this embodiment, Figure 2-Figure 4As shown, an arc baffle 5 is provided between the welding positioning mechanism 1 and the welding robot 4. The arc baffle 5 is used to shield the welding arc. The plane where the arc baffle 5 is located is vertically extended, and the plane where the arc baffle 5 is located is facing the welding positioning mechanism 1. When the welding robot 4 welds the photovoltaic cement pile on one welding positioning mechanism 1, the worker needs to place the various components of the photovoltaic cement pile on another welding positioning mechanism 1, so that there is an arc baffle 5 between the welding position and the worker, and the arc baffle 5 can shield the welding arc generated by the welding robot 4 during welding, reducing the harm to the worker.

[0031] In this embodiment, Figure 2-Figure 4 As shown, the welding positioning mechanism 1 includes a positioner 2 and a support unit 3. The support unit 3 is arranged on the positioner 2. The positioner 2 drives the support unit 3 to rotate to change the angle of the support unit 3 toward the welding robot 4. Each positioner 2 includes two brackets 6. The two brackets 6 are provided with motors. The two motors are coaxial. A rotating frame 7 is provided on the rotating shafts of the two motors. The support unit 3 is arranged on the rotating frame 7. The rotating frame 7 is driven to rotate by the rotation of the two motors, thereby changing the angle of the support unit 3 toward the welding robot 4. The positioner 2 changes the inclination angle of the support unit 3 so that the welding robot 4 can better weld the welding parts during welding, thereby ensuring the welding quality. Because some positions are difficult to weld directly, the photovoltaic cement piles need to be rotated to a certain angle before welding.

[0032] In this embodiment, Figure 5 As shown, the support unit 3 includes a base plate 8 fixed on the rotating frame 7, and the base plate 8 has a first positioning station and a second positioning station. The welding robot 4 is used to weld the photovoltaic cement pile into a whole at the first positioning station. After each part is welded and fixed, the worker places the photovoltaic cement pile at the second positioning station, so that the welding robot 4 welds the remaining unwelded parts of the photovoltaic cement pile that have been welded into a whole at the second positioning station, thereby completing the welding production of the photovoltaic cement pile. The first positioning station is closer to the welding robot 4 than the second positioning station.

[0033] The first positioning station is provided with a first positioning plate 10 and a second positioning plate 9 arranged at intervals. The first positioning plate 10 is a steel bar positioning component, and the second positioning plate 9 is a first ground pile pipe positioning component. The planes of the first positioning plate 10 and the second positioning plate 9 are parallel to each other and both face the left and right directions. The second positioning plate 9 and the first positioning plate 10 are both fixed on the bottom plate 8. The second positioning plate 9 is used for contacting and positioning the ground pile pipe 16, and the first positioning plate 10 is used for contacting and positioning multiple steel bars 17. Through the positioning of the two positioning plates, the ground pile pipe 16 and the steel bars 17 can be welded and fixed at a set distance.

[0034] like Figure 6 , Figure 7 As shown, the first cylinders 19 and the relatively arranged fixing plates 12 are provided on the opposite sides (i.e., the front and rear sides) of the second positioning plate 9, and the fixing plates 12 are provided movably, and the fixing plates 12 are compression parts, wherein the plane where the fixing plates 12 are located is perpendicular to the extension axis of the ground pile pipe 16. The two first cylinders 19 drive the corresponding fixing plates 12 to move relative to the ground pile pipe 16, so as to position the multiple steel bars 17 on the ground pile pipe 16 according to the set positions, thereby achieving the fixation between the multiple steel bars 17 and the ground pile pipe 16, and facilitating the subsequent welding robot 4 to weld the steel bars 17 and the ground pile pipe 16. The steel bars 17 and the ground pile pipe 16 are positioned at the first positioning station, so that the welding robot 4 can accurately find the welding position, and at the same time ensure the accuracy of the position between the steel bars 17 and the ground pile pipe 16.

[0035] like Figure 7 As shown, each fixing plate 12 is provided with a first groove 20 and a second groove 21 arranged sequentially from top to bottom, and the two fixing plates 12 move relative to each other toward the ground pile pipe 16, so that the first grooves 20 on the two fixing plates 12 simultaneously press the top steel bars 17 onto the ground pile pipe 16, and the two second grooves 21 respectively press the two steel bars 17 below onto the ground pile pipe 16, that is, the two first grooves 20 jointly fix a steel bar 17 located at the top, and the other two first grooves 20 respectively fix a steel bar 17 located at the bottom, thereby completing the fixing of the three steel bars 17 on the ground pile pipe 16. By pressing the steel bars 17 with the cooperation of the two first grooves 20 and the two second grooves 21, the three steel bars 17 are fixed at the set position of the ground pile pipe 16, thereby facilitating the welding of the welding robot 4, avoiding manual pressing and fixing of the steel bars 17, and reducing the labor intensity. At the same time, the two fixing plates 12 are also provided with an avoidance groove 22, which is located between the first groove 20 and the second groove 21. The avoidance groove 22 is used to avoid the ground pile pipe 16 to prevent the ground pile pipe 16 from affecting the top pressure fixation of the fixing plate 12 on the steel bar 17.

[0036] like Figure 5 , Figure 8As shown, the first positioning station is provided with a plurality of first support plates 13 arranged at intervals in the left and right directions and a plurality of push blocks 24 movably arranged in the left and right directions. The push blocks 24 are stirrup clamping parts. The first support plate 13 and the push blocks 24 constitute a stirrup positioning assembly. The first positioning station is also provided with a plurality of second cylinders 23. The plurality of second cylinders 23 correspond to the plurality of push blocks 24 one by one. The second cylinders 23 are used to drive the push blocks 24 to move in the left and right directions. The plurality of first support plates 13 are used to support the steel bars 17. The plurality of first support plates 13 are located between the second positioning plate 9 and the first positioning plate 10 so that the positioned steel bars 17 can be placed on the first support plate 13. The push blocks 24 correspond to the first support plates 13 one by one. The second cylinders 23 drive the push blocks 24 to move to press the triangular hoop 18 onto the first support plate 13 so that the triangular hoop 18 is positioned. At this time, the triangular hoop 18 contacts the corresponding first support plate 13. In this way, the positioning and fixing of the positions of the plurality of triangular hoops 18 are achieved, the stability of the welding robot 4 during welding is ensured, and the welding quality is improved.

[0037] In other embodiments, the first cylinder 19 and the second cylinder 23 may also be replaced by electric push rods, hydraulic cylinders, etc.

[0038] like Fig. 9 As shown, the first support plate 13 has a first placement groove 27, a second placement groove 28 and a third placement groove 29 for placing the corresponding steel bars 17, the first placement groove 27 is located above the second placement groove 28 and the third placement groove 29, and the second placement groove 28 and the third placement groove 29 are respectively arranged on both sides of the first placement groove 27. The arrangement of the first placement groove 27, the second placement groove 28 and the third placement groove 29 allows the placed steel bars 17 to form a triangular structure, which is convenient for welding the photovoltaic cement piles at the first positioning station, and also convenient for taking and placing the photovoltaic cement piles.

[0039] The second positioning station is provided with a third positioning plate 11 for contacting and positioning the ground pile pipe 16. The third positioning plate 11 positions the ground pile pipe 16 so that the welding robot 4 can accurately find the welding position, thereby ensuring the welding quality.

[0040] In this embodiment, the second positioning plate 9 and the first positioning plate 10 have the same positioning orientation (the steel bars and the pile pipe are both pressed and positioned on the left side), and the positioning orientation of the third positioning plate 11 is opposite to the positioning orientation of the second positioning plate 9 and the first positioning plate 10.

[0041] When the welding robot 4 is welding the photovoltaic cement ground piles on the second positioning station, the workers can load and position the ground pile pipe 16, triangular hoop 18 and steel bar 17 at the first positioning station to ensure that the two positioning stations will not be idle. By alternately welding and loading the photovoltaic cement ground piles at the first positioning station and the second positioning station, the number of manual material handling times can be reduced, the labor intensity is reduced, and the production efficiency can also be improved.

[0042] In this embodiment, at the first positioning station, three steel bars 17 are distributed on the first support plate 13 in a triangular structure.

[0043] like Figure 8-Figure 10 As shown, a first pressing block 25 is provided on one side of the first support plate 13 close to the corresponding push block 24, and a second pressing block 26 is provided on the push block 24 corresponding to the first support plate 13. The push block 24 moves so that the second pressing block 26 presses the corresponding triangular hoop 18 onto the first pressing block 25 to complete the fixing of the triangular hoop 18. The triangular hoop 18 for the photovoltaic cement pile is fixed by the pressing fit between the first pressing block 25 and the second pressing block 26, thereby preventing the triangular hoop 18 from shaking during welding, which makes it easier for the welding robot 4 to weld the triangular hoop 18 and improves the welding quality.

[0044] In this embodiment, there are three first pressing blocks 25 and three second pressing blocks 26, wherein the three first pressing blocks 25 are distributed in a triangular structure, wherein one first pressing block 25 is located at the top, and the remaining two first pressing blocks 25 are located at the bottom. Among the three second pressing blocks 26, two second pressing blocks 26 are located at the top, and the remaining second pressing block 26 is located at the bottom. The second pressing blocks 26 move and contact the triangular hoop 18, and press the triangular hoop 18 to move onto the first pressing blocks 25, wherein each second pressing block 26 presses against one side of the triangular hoop 18, and each first pressing block 25 presses against two adjacent sides of the triangular hoop 18, that is, one second pressing block 26 presses against one side of the triangular hoop 18, and one first pressing block 25 presses against two sides of the triangular hoop 18. The pressing contact in this manner makes the fixation of the triangular hoop 18 more stable, thereby improving the welding quality.

[0045] like Figure 5 and Fig.11As shown, a plurality of second support plates 14 arranged at intervals are provided on the second positioning station, and the plurality of second support plates 14 are used to support the steel bars 17. The second support plate 14 has a fourth placement slot 30, a fifth placement slot 31 and a sixth placement slot 32 for placing the corresponding steel bars 17, the sixth placement slot 32 is located below the fourth placement slot 30 and the fifth placement slot 31, and the fourth placement slot 30 and the fifth placement slot 31 are disposed on both sides of the sixth placement slot 32. When the photovoltaic cement pile is transferred from the first positioning station to the second positioning station, the photovoltaic cement pile needs to be turned over and placed, so the fourth placement slot 30, the fifth placement slot 31 and the sixth placement slot 32 need to be arranged in such a way that the placed steel bars 17 form an inverted triangular structure, which is convenient for welding the photovoltaic cement pile at the second positioning station, and also convenient for taking and placing the photovoltaic cement pile.

[0046] like Figure 5 As shown, both the first positioning station and the second positioning station have a support seat 15 for supporting the ground pile pipe 16. The support seat 15 supports the corresponding ground pile pipe 16, so that the ground pile pipe 16 can be stably placed on the first positioning station and the second positioning station, so that the welding quality of the photovoltaic cement ground pile is improved.

[0047] The support seat 15 has an upwardly open V-shaped groove, in which the ground pile pipe 16 is placed. The structure of the V-shaped groove enables the support seat 15 to be suitable for ground pile pipes 16 of various diameters, and also improves the stability of the placement of the ground pile pipe 16.

[0048] The working process of the present invention is as follows: The welding robot 4 in this embodiment performs welding operations alternately between the two welding positioning mechanisms 1 .

[0049] An unwelded photovoltaic cement pile is placed on the first positioning station of one of the welding positioning mechanisms 1, and another photovoltaic cement pile is placed on the second positioning station. One side of the photovoltaic cement pile has been welded, and the other side is facing upward, so that the welding robot 4 can weld the unwelded position. After that, the welding robot 4 can be started to weld the two photovoltaic cement piles on the first positioning station and the second positioning station of the welding positioning mechanism 1.

[0050] While the welding robot 4 is welding the two photovoltaic cement ground piles on the first positioning station and the second positioning station of the previous welding positioning mechanism 1, the worker goes to another welding positioning mechanism 1 and places the photovoltaic cement ground piles on its first positioning station and the second positioning station. The placement process and method are consistent with the placement process and method of the two photovoltaic cement ground piles on the previous welding positioning mechanism 1.

[0051] After the welding robot 4 completes the welding of the two photovoltaic cement piles on the previous welding positioning mechanism 1 , it starts to weld the two photovoltaic cement piles on the next welding positioning mechanism 1 .

[0052] During the process of the welding robot 4 welding the two photovoltaic cement ground piles on the rear welding positioning mechanism 1, the worker takes the photovoltaic cement ground piles that have been welded on the second positioning station of the previous welding positioning mechanism 1 away and puts them into storage, then turns over the photovoltaic cement ground pile on the first positioning station and places it on the second positioning station, and replaces a new unwelded photovoltaic cement ground pile on the first positioning station.

[0053] After the welding robot 4 completes the welding operation on the two photovoltaic cement piles on the rear welding positioning mechanism 1 , the welding robot 4 starts to weld the two photovoltaic cement piles on the front welding positioning mechanism 1 .

[0054] The welding robot 4 circulates back and forth between the two welding positioning mechanisms 1 to alternately weld the photovoltaic cement piles.

[0055] Example 2 The difference between this embodiment and embodiment 1 is that there are two welding positioning mechanisms 1 in embodiment 1, while there is only one welding positioning mechanism 1 in this embodiment, and the welding robot 4 operates alternately between the first positioning station and the second positioning station on one welding positioning mechanism 1.

[0056] Example 3 The difference between this embodiment and embodiment 1 is that the number of welding positioning mechanisms 1 in embodiment 1 is two, while the number of welding positioning mechanisms 1 in this embodiment is more than three. These welding positioning mechanisms 1 are distributed in a circular array with the welding robot 4 as the center, and the welding robot 4 performs welding operations in sequence along these welding positioning mechanisms 1.

[0057] Example 4 The difference between this embodiment and embodiment 1 is that in embodiment 1, there are three first pressing blocks 25 and three second pressing blocks 26, while in this embodiment, there is only one first pressing block 25 and one second pressing block 26. One first pressing block 25 and one second pressing block 26 can press the three sides of the triangular hoop 18 at the same time to achieve the pressing, positioning and fixing of the triangular hoop 18.

[0058] Example 5 The difference between this embodiment and embodiment 1 is that the third positioning plate 11 in embodiment 1 is used to abut against the positioning ground pile pipe 16, while the third positioning plate 11 in this embodiment is used to position the steel bar 17, and one end of the steel bar 17 of the unwelded ground pile pipe 16 abuts against the third positioning plate 11, thereby realizing the positioning of the photovoltaic cement ground pile at the second positioning station.

[0059] Example 6 The difference between this embodiment and embodiment 1 is that the third positioning plate 11 in embodiment 1 is used to abut against the positioning pile pipe 16, while the third positioning plate 11 in this embodiment is used to position the triangular hoop 18. When performing welding operations on photovoltaic cement piles of the same specification, the position order of the triangular hoop 18 on the positioned photovoltaic cement piles is fixed. During positioning, the third positioning plate 11 abuts against the triangular hoop 18 to press against it, so as to realize the positioning of the photovoltaic cement pile at the second positioning station.
