It should also be noted that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0059] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0060] Please refer to Figure 1 to Figure 12 , an embodiment of the present invention provides a metal signal tower welding device, comprising:

[0061] Base frame mechanism 2;

[0062] The ring welding mechanism 3 includes a first ring body 31 and a second ring body 32 which are arranged above the base frame mechanism 2 and are coaxially arranged along a first direction. The axis of the first ring body 31 and the second ring body 32 is a central axis, and the extension direction of the central axis is the first direction. The inner diameter of the first ring body 31 is greater than the inner diameter of the second ring body 32.

[0063] The first driving assembly 4 is provided on the base frame mechanism 2 and is used to drive the first ring body 31 and the second ring body 32 to rotate with the central axis as the axis and at the same angular velocity;

[0064] Eight clamping mechanisms 5 are respectively arranged at four quadrants of the first ring body 31 and the second ring body 32, and are used to clamp the main support column 11 and assist the main support column 11 in self-rotation. Each main support column 11 has a first axis, and each first axis forms a first angle 9 with the central axis. The opening of each first angle 9 faces away from the second ring body 32.

[0065] Two second driving assemblies 8 are respectively arranged on both sides of the ring welding mechanism 3 along the second direction, and are used to drive the corresponding main support column 11 to rotate around the first axis, and the first direction and the second direction are perpendicular to each other.

[0066] like Figure 1 , Figure 2 and Figure 3 As shown, the first direction is Figure 1 The left and right directions in the second direction are Figure 1 In the front-to-back direction, the first ring body 31 or the second ring body 32 has two quadrant points in the vertical direction and two quadrant points along the front-to-back direction. With the quadrant point as the center, the vicinity of the first ring body 31 or the second ring body 32 is the quadrant point area, and the clamping mechanism 5 is installed with four quadrant point areas; the four main support columns 11 can be fixed by eight clamping mechanisms 5, the inner diameter of the first ring body 31 is larger than the inner diameter of the second ring body 32, so each first axis forms a first angle 9 with the central axis, and the four main support columns 11 form a first angle 9 as shown in FIG. Figure 1 The left opening is large and the right opening is small, which is the same as the structure of the signal tower section 1, so that workers can quickly install the reinforcing ribs 15 between the connecting plates 14 after welding is completed; further, the two second driving components 8 are respectively located on the front and rear sides of the ring welding mechanism 3, and drive the main support column 11 located in the two quadrant point areas in the front and rear directions. When the main support column 11 rotates, welding can be performed between the end cover 12 and the main support column 11, as well as welding between the connecting plate 14 and the main support column 11, and the two welding processes are distributed to the two second driving components 8, so that the two welding processes will not interfere with each other, thereby improving the welding efficiency.

[0067] In some embodiments, the ring welding mechanism 3 is installed with four main support columns 11 through four clamping mechanisms 5, and the base frame mechanism 2 is provided with station bottom plates 22 at both ends along the second direction, and a welding mechanism 6 is provided on one station bottom plate 22, and the welding mechanism 6 is used to weld the connecting piece 14 and the corresponding main support column 11, and a positioning mechanism 7 is provided on the other station bottom plate 22, and the positioning mechanism 7 is used for positioning welding of the end caps 12 at both ends of the corresponding main support column 11;

[0068] like Figure 1 , Figure 2 and Figure 3As shown, the second driving assembly 8 located at the rear side of the ring welding mechanism 3 corresponds to the welding mechanism 6, and is used to process the welding between the connecting piece 14 and the main support column 11, and the second driving assembly 8 located at the front side of the ring welding mechanism 3 corresponds to the positioning mechanism 7. After positioning the end covers 12 at both ends of the main support column 11, the second driving assembly 8 is cooperated to perform welding. The welding mechanism 6 and the positioning mechanism 7 are used to accelerate the welding efficiency of the main support column 11 and the accessories, and the welding mechanism 6 and the positioning mechanism 7 are divided into two workstations to realize synchronous processing, avoid crowding of personnel at only one workstation, and thus improve welding efficiency.

[0069] In some embodiments, the welding mechanism 6 includes a plurality of electric push rods 61 disposed on the workstation bottom plate 22, and a semi-ring support plate 62 is disposed at the top of each electric push rod 61, and the inner wall of each semi-ring support plate 62 abuts against the bottom of the outer wall of the corresponding main support column 11, and each semi-ring support plate 62 is provided with a positioning plate 63 away from the central axis end, and the positioning plate 63 is provided with a positioning groove 64 near the central end of the semi-ring support plate 62, and the connecting piece 14 can be disposed in the positioning groove 64;

[0070] like Figure 3 and Figure 8 As shown, the number of electric push rods 61 is the same as the number of connecting plates 14. The connecting plates 14 are installed in the positioning grooves 64. The electric push rods 61 are started to push the semi-ring support plate 62 and the positioning plate 63 upward. When the inner wall of the semi-ring support plate 62 abuts against the bottom of the outer wall of the main support column 11 at the rear end, the positioning plate 63 is close to the main support column 11. The worker can weld the first weld between the connecting plate 14 and the main support column 11, and then drive the main support column 11 to rotate by the second drive assembly 8, adjust the position of the main support column 11, and weld the second weld between the main support column 11 and the connecting plate 14.

[0071] In some embodiments, the welding mechanism 6 also includes a vertical plate 65 arranged on one side of the electric push rod 61, and two limit columns 66 are arranged at both ends of the top surface of the vertical plate 65 along the first axis direction of the corresponding main support column 11, and a sliding rod 67 is slidably connected between the two limit columns 66, and the extension direction of the sliding rod 67 is parallel to the first axis of the corresponding main support column 11. A welding gun collar 68 is provided in the middle of the sliding rod 67, and the welding gun collar 68 has a first baffle 69 at the end close to the main support column 11 and a second baffle 610 at the other end. A welding gun is clamped in the welding gun collar 68, and two welds parallel to the first axis are provided between a connecting piece 14 and the main support column 11. When the first baffle 69 abuts against the vertical plate 65, the welding gun welds to form a first weld, and when the second baffle 610 abuts against the vertical plate 65, the welding gun welds to form a second weld;

[0072] like Figure 3 and Figure 8As shown, the welding gun is clamped into the inside of the welding gun collar 68, and the welding gun collar 68 is rotated with the slide bar 67 as the axis to make the first baffle 69 abut against the vertical plate 65. At this time, the welding gun is in a downward tilted state. At this time, the connecting piece 14 is installed in the positioning groove 64 to achieve welding of the first weld seam between the connecting piece 14 and the main support column 11. Then, the main support column 11 is driven to rotate by the second driving assembly 8, and the position of the main support column 11 is adjusted to make the connecting piece 14 rotate with the main support column 11 until it is perpendicular to the positioning plate 63 and then stops. Then, the welding gun collar 68 is swung with the slide bar 67 as the axis to make the second baffle 610 abut against the vertical plate 65. At this time, the welding gun is in a slightly upward tilted state to weld the second weld seam. Compared with manual welding, it is necessary to grasp the two weld seam positions by yourself. The welding gun collar 68 can be used to position the first weld seam and the second weld seam more quickly, thereby improving welding efficiency.

[0073] In some embodiments, the positioning mechanism 7 includes:

[0074] The terminal positioning part includes a first positioning plate 73 provided on one side of the second ring body 32 along the extension direction of the first axis, and the end cover 12 at one end of the main support column 11 is installed on the first positioning plate 73 close to the main support column 11;

[0075] The front end positioning part includes a second positioning plate 79 provided on one side of the first ring body 31 along the extension direction of the first axis, and the end cover 12 at the other end of the main support column 11 is installed on the second positioning plate 79 close to the main support column 11;

[0076] like Figure 1 and Figure 3 As shown, because the positioning mechanism 7 is located on the front side of the ring welding mechanism 3, the two end covers 12 are positioned by the first positioning plate 73 and the second positioning plate 79. When the main support column 11 at the front end is clamped by the clamping mechanism 5, one end of the main support column 11 abuts against one end cover 12, and the other end abuts against the other end cover 12, so as to realize the positioning of the main support column 11; further, because there is a first angle 9 between the first axis and the central axis, the first positioning plate 73 and the second positioning plate 79 have an extension direction parallel to the central axis due to processing requirements. Therefore, before welding the main support column 11 and the end cover 12, workers are required to spot weld the end cover 12 and the main support column 11, and then remove the first positioning plate 73 and the second positioning plate 79, and drive the main support column 11 to rotate by the second drive assembly 8. Workers can weld the main support column 11 and the end cover 12 to form an elliptical weld.

[0077] In some embodiments, the terminal positioning part includes a first positioning column 71 disposed on the base frame mechanism 2, the top of the first positioning column 71 is threadedly connected with a second screw 72, the second screw 72 is provided with a first positioning plate 73 near the end of the main support column 11, the axis extension direction of the first positioning plate 73 and the second screw 72 is a first direction, the first positioning plate 73 is provided with a clamping rubber block 710 arranged around the edge of the first positioning plate 73 away from the end of the second screw 72, and the end cover 12 is clamped between a plurality of clamping rubber blocks 710;

[0078] like Figure 1 and Fig. 9 As shown, by rotating the second screw 72, the first positioning plate 73 can be driven to retract toward the side away from the main support column 11 through the action of the thread, and will not interfere with the self-rotation of the main support column 11; in addition, a second rotary handle 76 is provided on the side of the second screw 72 away from the first positioning plate 73, which is convenient for using to rotate the second screw 72. Further, the second screw 72 and the first positioning plate 73 are rotatably connected, and a second guide column 74 is provided at the end of the first positioning plate 73 away from the main support column 11, and the second guide column 74 passes through the first positioning column 71, and a third baffle plate 75 is provided at the end of the second guide column 74 away from the first positioning plate 73. When the third baffle plate 75 contacts the first positioning column 71, the first positioning plate 73 can no longer move toward the side of the main support column 11, thereby realizing the positioning of the first positioning plate 73 and the positioning of the end cover 12 at one end of the corresponding main support column 11.

[0079] In some embodiments, the front end positioning portion includes a second positioning column 77 disposed on the base frame mechanism 2, the second positioning column 77 is rotatably connected to the base frame mechanism 2 through an elastic shaft assembly 78, a second positioning plate 79 is disposed at the top of the second positioning column 77 close to the end of the main support column 11, the axis of the second positioning plate 79 extends in the first direction, and a clamping rubber block 710 is disposed around the edge of the second positioning plate 79 at the end of the second positioning plate 79 away from the main support column 11;

[0080] The elastic shaft assembly 78 includes two first shaft seats 781 arranged on the base frame mechanism 2, and two second shaft seats 782 arranged on the second positioning column 77. A swing shaft 783 is installed between each first shaft seat 781 and each second shaft seat 782. The axis extension direction of the swing shaft 783 is the second direction. A torsion spring 784 is provided on the outer sleeve of the swing shaft 783. One end of the torsion spring 784 is connected to the base frame mechanism 2, and the other end is connected to the second positioning column 77. The torsion spring 784 drives the second positioning column 77 to swing toward the main support column 11 side with the swing shaft 783 as the axis.

[0081] like Figure 2 , Fig.10 and Fig.11As shown, the second positioning column 77 is driven by the torsion spring 784 to swing toward the main support column 11 with the swing shaft 783 as the axis, driving the second positioning plate 79 to push the main support column 11 to move toward the first positioning plate 73, and the end cover 12 installed on the second positioning plate 79 abuts against one end of the main support column 11. After the main support column 11 moves, its other end abuts against the end cover 12 installed on the first positioning plate 73, and finally the positioning between the two end covers 12 and the main support column 11 is achieved; further, the worker spot welds the end cover 12 and the main support column 11, rotates the second screw 72 to remove the first positioning plate 73, and then swings the second positioning column 77 to make the end cover 12 disengage from the clamping rubber block 710, and then the main support column 11 can be driven to rotate by the second driving assembly 8, and the main support column 11 and the end cover 12 are welded to form an elliptical weld.

[0082] In some embodiments, the first ring body 31 and the second ring body 32 have four quadrant points respectively, and the clamping mechanism 5 includes a first fixing plate 51 and a second fixing plate 52 arranged on both sides of a quadrant point, and the first fixing plate 51 and the second fixing plate 52 are connected to the inner wall of the first ring body 31 or the inner wall of the second ring body 32 at ends away from the central axis, and a guide component 56 is provided at the end of the first fixing plate 51 facing the second fixing plate 52, and a first screw rod 53 is threadedly connected to the middle of the second fixing plate 52, and the first screw rod 53 is rotatably connected to the guide component 56 at the end close to the first fixing plate 51;

[0083] The two guide assemblies 56 each include two rotatable clamping rollers 564 at their respective ends, the main support column 11 is placed between the four clamping rollers 564, and the axis extension direction of the four clamping rollers 564 is parallel to the first axis of the corresponding main support column 11;

[0084] like Figure 1 , Figure 5 and Figure 7 As shown, since the clamping mechanism 5 is arranged in the first ring body 31 and the second ring body 32 in the same manner, the first ring body 31 is used as the basis for the introduction. The center point of the first ring body 31 is connected with the quadrant point to form four radius lines, and the first fixed plate 51 and the second fixed plate 52 are respectively located on both sides of the corresponding radius lines. During installation, the main support column 11 is installed between the two corresponding clamping rollers 564 on the first fixed plate 51, and then the first screw 53 is rotated to make the two corresponding clamping rollers 564 on the second fixed plate 52 move toward the first fixed plate 51 side, and finally the four clamping rollers 564 are formed to clamp the main support column 11. Since the four clamping rollers 564 can rotate by themselves, after the main support column 11 is fixed, the main support column 11 is restricted from moving along the first axis direction of itself, so that it can only rotate by itself.

[0085] Furthermore, the guide assembly 56 also includes a mounting shaft 563 disposed in the middle of the clamping roller 564, and both ends of the mounting shaft 563 are fitted with connecting plates 562, one end of the connecting plate 562 is connected to a base plate 561, and the end of the base plate 561 away from the connecting plate 562 is connected to the first fixed plate 51 or the second fixed plate 52, so as to ensure that the mounting shaft 563 remains stable and the clamping roller 564 rotates around the mounting shaft 563 as the axis; further, as Figure 7 As shown, the first screw 53 is rotatably connected to the base plate 561, and a plurality of first guide pillars 55 are provided on the base plate 561 connected to the second fixed plate 52. Each first guide pillar 55 passes through the second fixed plate 52 to limit the rotation of the base plate 561, thereby ensuring that the base plate 561 drives the base plate 561 and the clamping roller 564 to move stably toward the first fixed plate 51 side. In addition, a first rotating handle 54 is installed at one end of the first screw 53, and the user can conveniently rotate the first screw 53 through the first rotating handle 54.

[0086] In some embodiments, the first drive assembly 4 includes:

[0087] A driving part, comprising a first driving wheel 41 and a first driven wheel 42 disposed at the bottom of the first ring body 31 and located on both sides of the central axis along the second direction, and a first motor 44 disposed on the base frame mechanism 2, wherein the axis extension directions of the first driving wheel 41 and the first driven wheel 42 are both in the first direction, and the outer walls of the first driving wheel 41 and the first driven wheel 42 are both in contact with the outer wall of the first ring body 31, and the first motor 44 drives the first driving wheel 41 to rotate, thereby driving the first ring body 31 and the first driven wheel 42 to rotate;

[0088] A second drive unit, a second driving wheel 410 and a second driven wheel 411, which are arranged at the bottom of the second ring body 32 and located on both sides of the central axis along the second direction, and a second motor 412, which is arranged on the base frame mechanism 2. The axis extension directions of the second driving wheel 410 and the second driven wheel 411 are both in the first direction, and the outer walls of the second driving wheel 410 and the second driven wheel 411 are both in contact with the outer wall of the second ring body 32. The second motor 412 drives the second driving wheel 410 to rotate, thereby driving the second ring body 32 and the second driven wheel 411 to rotate;

[0089] like Figure 1 , Figure 2 and Figure 4As shown, the first motor 44 drives the first driving wheel 41 to make the first ring body 31 rotate above the first driving wheel 41 and the first driven wheel 42, and the second motor 412 and the second driving wheel 410 make the second ring body 32 rotate above the second driving wheel 410 and the second driven wheel 411. Since the diameters of the first ring body 31 and the second ring body 32 are different, the outer diameters of the first driving wheel 41 and the second driving wheel 410 are different, so the rotation speeds of the first motor 44 and the second motor 412 are different, which can ensure that the first ring body 31 and the second ring body 32 rotate at the same angular velocity; optionally, a main mounting column 43 is provided on the base frame mechanism 2, and the first driven wheel 42 and the second driven wheel 411 can be rotatably mounted on the main mounting column 43. Although the rotation speeds of the two are different, they both rotate and will not interfere with each other.

[0090] In some embodiments, the first driving assembly 4 further includes a limiting portion, which includes a first connecting column 45 and a second connecting column 46 disposed in the middle of the base frame mechanism 2, and the top ends of the first connecting column 45 and the second connecting column 46 are rotatably connected with an auxiliary pressing cylinder 47, and the outer wall of the auxiliary pressing cylinder 47 disposed on the first connecting column 45 abuts against the inner wall edge of the first ring body 31, and the auxiliary pressing cylinder 47 disposed on the second connecting column 46 abuts against the inner wall edge of the second ring body 32;

[0091] The limiting part also includes two rubber washers 49 sleeved on the outer walls of the first ring body 31 and the second ring body 32. The first driving wheel 41, the first driven wheel 42, the second driving wheel 410 and the second driven wheel 411 are sleeved with limiting edge rings 48 at both ends along the first direction. The outer walls of the first driving wheel 41 and the first driven wheel 42 are both in contact with the outer wall of the first ring body 31 through the rubber washers 49. The outer walls of the second driving wheel 410 and the second driven wheel 411 are both in contact with the outer wall of the second ring body 32 through the rubber washers 49. The two end surfaces of the rubber washers 49 along the first direction are respectively in contact with the corresponding limiting edge rings 48.

[0092] like Figure 4 , Figure 5 and Figure 6 As shown, the first ring body 31 and the second ring body 32 are limited by the limiting portion to improve the stability of the two during rotation. Taking the first ring body 31 as an example, when the first driving wheel 41 and the first driven wheel 42 are lifted upward, the auxiliary pressure cylinder 47 abuts against the first ring body 31 downward and rotates, thereby ensuring the stable rotation of the first ring body 31. Furthermore, the rubber gasket 49 of the first ring body 31 can provide a higher static friction force, so that the first driving wheel 41 can drive the first ring body 31 more stably and reduce slipping. Furthermore, the limiting edge ring 48 limits the left and right deviation of the rubber gasket 49, thereby limiting the deviation of the first ring body 31 and realizing the stable rotation of the first ring body 31.

[0093] In some embodiments, two second drive assemblies 8 are respectively arranged on two workstation bottom plates 22, and the second drive assembly 8 includes a secondary support column 81 arranged on the workstation bottom plate 22, a third mounting plate 82 is arranged on the top of the secondary support column 81, a third motor 83 is arranged on the top of the third mounting plate 82, and a third drive wheel 84 is sleeved on the output shafts of the two third motors 83. The two third motors 83 drive the corresponding third drive wheels 84 to rotate, thereby driving the main support column 11 at the corresponding position to rotate;

[0094] like Figure 2 and Figure 3 As shown, the surface of the third driving wheel 84 is made of rubber material. The third driving wheel 84 rotates to drive the main support column 11 at the corresponding position to rotate, thereby achieving the purpose of the second driving component 8 driving the corresponding main support column 11 to rotate. In addition, there are four secondary support columns 81, which are respectively arranged at the four corners of the bottom end of the third mounting plate 82 to ensure the stability of the third mounting plate 82 and the third motor 83.

[0095] In some embodiments, the base frame mechanism 2 includes a rectangular frame 21, which serves as the basis for the entire device to contact the ground. Two groups of motor mounting plates are provided in the middle of the rectangular frame 21, and each group of motor mounting plates includes two first mounting plates 24 distributed along the first direction and extending along the second direction. One group of two first mounting plates 24 is used to install the first motor 44, and the other group of two first mounting plates 24 is used to install the second motor 412, thereby realizing the installation of two motors. Furthermore, a pressing cylinder support plate 23 extending in the first direction is provided in the middle of the rectangular frame 21, and the bottom ends of the first connecting column 45 and the second connecting column 46 are both connected to the pressing cylinder support plate 23. If the entire plate is used to lay on the rectangular frame 21, the first driving wheel 41 or the second driving wheel 410 will interfere with it. Therefore, when designing, the entire plate is divided into the middle pressing cylinder support plate 23 and the workstation bottom plates 22 at the front and rear ends.

[0097] Step 1: Preparation stage: rotate the second screw 72, when the third baffle 75 abuts against the first positioning column 71, the first positioning plate 73 is positioned, and one end cover 12 is installed on the first positioning plate 73, and then the second positioning column 77 is swung to make the second positioning plate 79 away from the first ring body 31, and the second positioning column 77 is manually held and fixed, and then the other end cover 12 is installed on the second positioning plate 79;

[0098] Step 2: Install the main support column 11. Install the main support column 11 to the quadrant point area located at the front end of the first ring body 31 and the second ring body 32.

[0099] Step 3, loosen the second positioning column 77, and the torsion spring 784 drives the second positioning column 77 to swing toward the main support column 11 side with the swing shaft 783 as the axis, driving the second positioning plate 79 to push the main support column 11 to move toward the first positioning plate 73, and the end cover 12 installed on the second positioning plate 79 abuts against one end of the main support column 11. After the main support column 11 moves, its other end abuts against the end cover 12 installed on the first positioning plate 73, and finally realizes the positioning between the two end covers 12 and the main support column 11, and then uses the clamping mechanism 5 to complete the stable clamping of the main support column 11;

[0100] Step 4: Manually spot weld the end cover 12 and the main support column 11, then remove the first positioning plate 73 and the second positioning plate 79, that is, rotate the second screw 72 to remove the first positioning plate 73, and then swing the second positioning column 77 to make the end cover 12 separate from the clamping rubber block 710, and then the main support column 11 can be driven by the second driving assembly 8 to rotate, and the main support column 11 and the end cover 12 are welded to form an elliptical weld;

[0101] Step 5: Drive the first ring body 31 and the second ring body 32 to rotate through the first driving assembly 4, so as to drive the main support column 11 that has been spot-welded to rotate to the top of the entire device, and then repeat steps 1 to 4 to complete the fixing of the four main support columns 11;

[0102] Step 6: The second driving assembly 8 at the front end drives the main support column 11 at the front end, and the user can weld between the end cover 12 and the main support column 11 to form an elliptical weld. The second driving assembly 8 at the rear end drives the main support column 11 at the rear end, and the user can weld between the connecting piece 14 and the main support column 11 to form a first weld and a second weld. After all the end covers 12 and the connecting piece 14 are welded, the rotation angle of the main support column 11 can be adjusted by the second driving assembly 8 to weld the rib plate 13 between the end cover 12 and the main support column 11.

[0103] Step seven, adjust the position of the connecting piece 14 corresponding to the main support column 11 through the second drive component 8, and then drive the first ring body 31 and the second ring body 32 to rotate through the first drive component 4, adjust the remaining main support columns 11 to the position of the second drive component 8, and adjust the position of the connecting piece 14 again by the second drive component 8, and finally realize the position of all the connecting pieces 14 of the four main support columns 11, so as to facilitate the assembly of the reinforcing ribs 15 with the corresponding connecting pieces 14, and then complete the welding and assembly of the entire signal tower section 1.
