Description

Technical Field

[0001] This utility model belongs to the field of tower foot welding technology, and specifically relates to a tower foot welding system. Background Technology

[0002] The tower foot is the part of the iron tower where the tower body meets the foundation. It is usually buried underground and connected to the bottom of the tower to stabilize and bear the load. The tower foot involves a variety of components, including a base plate and multiple connecting plates on the upper part of the base plate. The tower foot is usually fixed using a welding platform, and then the base plate and multiple connecting plates are welded together using welding assemblies to form the tower.

[0003] For example, patent application number CN202221056508.X discloses a base assembly and a cross-shaped clamping device mounted on the base assembly. The center of the cross-shaped clamping device is fixed to the drive shaft of a rotary motor, and a welding robot is fixed on the base assembly on one side of the cross-shaped clamping device. The welding robot is fixed at one corner of the base assembly. The welding robot cannot move independently and needs to move with the base assembly. Its welding range is limited. When welding various components of the tower foot, the angle of the tower foot needs to be constantly adjusted to cooperate with the welding robot. Since different types of tower feet have different sizes and structures, especially when welding larger tower feet, the welding size exceeds the welding range of the welding robot. In order to ensure that the welding head of the welding robot can weld in place, the tower foot needs to be flipped repeatedly. This causes the tower foot to easily shift its position during the flipping process. Moreover, too many flips are not conducive to the stability of the tower foot, resulting in a decrease in welding efficiency. Utility Model Content

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0033] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0034] This utility model relates to a tower leg welding system, such as Figure 1-2 As shown, it includes:

[0035] The support assembly 1 includes a transverse track frame 11 and a longitudinal track frame 12 connected in a cross-shaped structure; a first track is provided on the transverse track frame 11 and a second track is provided on the longitudinal track frame 12; the welding assembly 15 is capable of sliding along the first track and the second track.

[0036] The support assembly, located below the bracket assembly 1, includes a base 2, a turntable 3, and a support mechanism 4. The base 2 includes a base body 21 and two frames 22 connected to the two sides above the base body 21, with the turntable 3 rotatably connected between the two frames 22. The support mechanism 4 is connected to the turntable 3. The support mechanism 4 includes a support seat 41 and a clamping assembly 42 and a fastening assembly 43 connected to the support seat 41. The support seat 41 has a first guide rail 6 and a second guide rail 7 with a cross-shaped structure. The clamping assembly 42 can slide along the first guide rail 6 to abut against the top corner of the tower foot. The fastening assembly 43 can slide along the second guide rail 7 to fasten the base plate of the tower foot.

[0037] like Figure 1 As shown, a cross-shaped transverse track frame 11 and a longitudinal track frame 12 are erected on the ground to form a support assembly 1. In application, the support assembly 1 is placed outside the support assembly, covering the top of the support assembly, so that the welding component 15 on the support assembly 1 can weld the tower feet fixed on the support assembly below. A first track is connected to the transverse track frame 11, and a second track is connected to the longitudinal track frame 12. The first track and the second track form a cross-shaped track path and are intersected. Since the welding component 15 can be moved and connected to the first track and the second track, the welding component 15 can move laterally along the first track and longitudinally along the second track, thereby covering the top surface of the tower feet set below in four positions (up, down, left, and right). This allows the welding component 15 to move in multiple positions outside the support assembly that is fixedly connected to the tower feet, thereby reducing the continuous rotation of the support assembly on the position of the tower feet, reducing the probability of positional deviation of the tower feet, and further improving the stability and efficiency of welding.

[0038] The turntable 3 in the support assembly is connected to the support mechanism 4. The turntable 3 can rotate relative to the frame 22 of the base 2. The support mechanism 4 can be connected to the fixed tower foot. Therefore, the position of the tower foot can be adjusted by adjusting the turntable 3. The welding component 15 can slide along the first track and the second track, thereby realizing the relative movement between the tower foot and the welding component 15, thereby further improving the welding efficiency.

[0039] The support mechanism 4 includes a support base 41 and a clamping assembly 42 and a fastening assembly 43 connected to the support base 41. The support base 41 has a first guide rail 6 and a second guide rail 7 with a cross-shaped structure. The clamping assembly 42 can slide along the first guide rail 6 to abut against the top corner of the tower foot. The fastening assembly 43 can slide along the second guide rail 7 to fasten the base plate of the tower foot. The fastening assembly 43 can position the tower foot to prevent it from shifting in the support mechanism 4 and prevent the tower foot from shifting during the rotation of the support mechanism 4 by the turntable 3. By abutting against the top corner of the tower foot through the clamping assembly 42, the positioning of the tower foot is further enhanced, preventing the tower foot from shifting during the welding process, achieving welding stability, and improving welding quality.

[0040] In a preferred embodiment, the transverse track frame 11 includes a first column 111, a second column 112, and a transverse support 113; the first column 111 is connected to one side of the transverse support 113, and the second column 112 is connected to the other side of the transverse support 113; a first track is provided on the transverse support 113.

[0041] The first column 111 is vertically distributed on one side of the horizontal support 113, and the second column 112 is vertically distributed on the other side of the horizontal support 113. The first column 111 and the second column 112 can adopt a telescopic structure, and the height of the first column 111 and the second column 112 can be adjusted according to the actual project needs.

The third column 121 and the fourth column 122 can adopt a telescopic structure, and their heights can be adjusted according to actual engineering needs. A second track is provided at the bottom of the longitudinal support 123.

[0044] The first and second tracks form a cross-shaped guide rail. The welding assembly 15 is connected to the cross-shaped guide rail and can slide along the first and second tracks respectively, enabling welding to the four sides (left, right, front, and back) of the tower foot below.

[0045] In a preferred embodiment, the base body 21 has a square structure, and the base body 21 is connected to the periphery of the base body 21 with a foot connector. The foot connector has a threaded hole, and the base body 21 is fastened to the ground by the foot bolts inserted into the threaded hole. The frame 22 is vertically connected to the base body 21, and the frame 22 has a drive device connected inside to rotate the turntable 3.

[0046] The frame 22 is located on both sides of the base body 21 along its length. The frame 22 is vertically connected to the base 2 and has a certain height to facilitate the placement of the tower feet and subsequent welding operations. The two sides of the turntable 3 are rotatably connected to the frame 22. Therefore, the drive device is installed inside the frame 22, which facilitates the rotation of the turntable 3 and saves space.

[0047] Furthermore, the drive device includes a drive motor, a gear assembly, and a rotating shaft; the rotating shaft is rotatably connected to the frame 22 via a bearing assembly, one side of the rotating shaft extends out of the frame 22 and is connected to the turntable 3, and the drive motor is connected to the rotating shaft via the gear assembly to drive the rotating shaft so that the turntable 3 rotates by a preset angle.

[0048] The drive motor is connected inside the frame 22. The gear assembly includes a large gear and a small gear. The small gear is fixedly connected to the output shaft of the drive motor, and the large gear is fixedly connected to the rotating shaft. The rotating shaft is rotatably connected to the frame 22 through a bearing assembly. The large gear and the small gear mesh and drive each other. When the drive motor starts, it drives the small gear and the large gear to rotate, thereby driving the rotating shaft to rotate. By controlling the rotation angle of the small gear and the large gear, the rotation angle of the rotating shaft is controlled, thereby controlling the rotation angle of the turntable 3, so as to adjust the rotation angle of the tower foot relative to the welding assembly 15, so as to facilitate the welding assembly 15 to weld the tower foot.

[0049] Furthermore, the turntable 3 includes a turntable body 31 and a turntable support 32; the turntable body 31 has a U-shaped structure, and both sides of the turntable body 31 are connected to the rotation shaft respectively; the bottom of the turntable body 31 is connected to the turntable support 32; the support mechanism 4 is rotatably connected to the turntable body 31 above the turntable support 32 via the rotating disk assembly 5.

[0050] like Figure 2 As shown, the turntable body 31 has a U-shaped structure. The two sides of the turntable body 31 are rotatably connected to the frame 22 through rotating shafts. The bottom of the turntable body 31 is connected to the turntable support base 32. The upper middle part of the turntable body 31 is connected to the rotating disk assembly 5. The upper part of the rotating disk assembly 5 is connected to the support mechanism 4. The rotating disk assembly 5 can rotate relative to the turntable body 31 in the horizontal direction, so the support mechanism 4 can be rotated in the horizontal direction, thereby realizing the adjustment of the horizontal angle of the tower foot.

[0051] Furthermore, the rotating disk assembly 5 includes a slewing bearing and a drive mechanism; the support mechanism 4 is rotatably connected to the turntable body 31 via the slewing bearing; the drive mechanism is connected within the turntable support base 32 and can drive the slewing bearing to rotate so as to drive the support mechanism 4 to rotate relative to the turntable body 31.

[0052] The rotary support of the rotating disk assembly 5 is rotatably connected to the middle of the turntable body 31. The rotary support includes an inner ring and an outer ring that are rotatably connected to each other, and there are rotating rolling elements between the inner ring and the outer ring. The outer ring is connected to the bottom of the support mechanism 4, the inner ring is connected to the turntable body 31, and the outer ring can be connected to the drive mechanism provided in the turntable support seat 32. The drive mechanism drives the outer ring to rotate relative to the inner ring, thereby realizing the rotation of the support mechanism 4 connected to the outer ring relative to the turntable body 31.

[0053] The drive mechanism can be a drive motor, which is installed inside the turntable support 32. The drive motor's drive shaft is connected to a drive gear, which meshes with the outer gear ring on the outer ring of the slewing bearing. The rotation of the drive motor's drive shaft and the drive gear drives the outer ring to rotate relative to the inner ring.

[0054] In a preferred embodiment, the first guide rail 6 has a first sliding cavity and a first sliding groove 8; the first sliding cavity is disposed inside the first guide rail 6, the first sliding groove 8 is connected to the first sliding cavity and extends along the length direction of the top surface of the first guide rail 6; the first lead screw is rotatably connected to the first sliding cavity corresponding to the first sliding groove 8; the clamping assembly can slide along the first lead screw;

[0055] The second guide rail 7 has a second sliding cavity and a second sliding groove 9; the second sliding cavity is disposed inside the second guide rail 7, the second sliding groove 9 is connected to the second sliding cavity and extends along the length direction of the top surface of the second guide rail 7; a second lead screw is rotatably connected inside the second sliding cavity, and the second lead screw corresponds to the second sliding groove 9; the fastening assembly 43 can slide along the second lead screw.

[0056] like Figure 2 As shown, the first guide rail 6 and the second guide rail 7 form a cross-shaped intersecting structure. The first guide rail 6 is located on both sides perpendicular to the extension direction of the second guide rail 7. Each end of the first guide rail 6 has a clamping assembly, which can move relative to each other to abut against the top corner of the tower foot, thus positioning the tower foot. Each end of the second guide rail 7 has a fastening assembly 43, which can move relative to each other to bolt the base plate of the tower foot. Specifically,

[0057] The first guide rail 6 has a first sliding cavity extending along its length inside, and a first sliding groove 8 is formed on the top surface of the first guide rail 6. The first sliding groove 8 is connected to the first sliding cavity. The first lead screw is set in the first sliding cavity, and the axial direction of the first lead screw is along the length direction of the first guide rail 6. The first lead screw is rotatably connected to the first guide rail 6.

[0058] Regarding the driving method of the first leadscrew, there are two possible implementation methods:

[0059] Implementation method 1: One end of the first lead screw can be connected to the first handwheel at the end of the first guide rail 6, and the first lead screw is driven to rotate by the first handwheel;

[0060] Implementation method 2: One end of the first lead screw can be connected to a motor, and the motor drives the first lead screw to rotate;

[0061] When the first lead screw is driven by a motor to rotate, the clamping assembly can move relative to the first lead screw. At this time, a sensor can be installed in the clamping assembly to detect the distance between the clamping assembly and the tower foot. When it is determined that the clamping assembly can contact and abut against the tower foot, the sensor uploads the data to the controller, and the controller controls the motor to stop rotating, so that the clamping assembly can automatically clamp the top corner of the tower foot.

[0062] The clamping assembly includes a clamping block and a first slider. The first slider is slidably connected to a first lead screw, and the clamping block is connected above the first slider. The first slider can partially extend out of a first groove 8 and connect with the clamping block. The first groove 8 limits the movement of the first slider, enhances the movement stability of the first slider, and further enhances the movement stability of the clamping block connected to the first slider.

[0063] The clamping block has a V-shaped groove 13 on the inner end face facing the tower foot. The bottom of the V-shaped groove 13 has an avoidance groove. The two side walls of the V-shaped groove 13 can abut against the side of the top corner of the tower foot. The avoidance groove can prevent the top edge of the top corner from interfering with the bottom of the V-shaped groove 13 when the top corner is placed in the V-shaped groove 13, so as to prevent the bottom of the V-shaped groove 13 from wearing down the top corner of the tower foot.

[0064] The second guide rail 7 has a second sliding cavity extending along its length inside, and a second sliding groove 9 is formed on the top surface of the second guide rail 7. The second sliding groove 9 is connected to the second sliding cavity. The second lead screw is set in the second sliding cavity, and the axial direction of the second lead screw is along the length direction of the second guide rail 7. The second lead screw is rotatably connected to the second guide rail 7.

[0065] The driving method for the second lead screw can be the same as that for the first guide rail 6:

[0066] A second handwheel can be connected to one end of the second lead screw, and the second lead screw can be driven by manually rotating the second handwheel to adjust the spacing of the fastening components 43 on both sides of the second lead screw;

[0067] Alternatively, a motor can be connected to one end of the second lead screw, which automatically drives the second lead screw to rotate, thereby automatically adjusting the distance between the fastening components 43 on both sides. When it is necessary to automatically adjust the distance between the fastening components 43, a displacement sensor can be connected to the fastening component 43 to detect the degree of connection between the fastening component 43 and the tower foot. When the connection hole 10 of the fastening component 43 is aligned with the threaded hole of the base plate of the tower foot, the displacement sensor can transmit a signal to the controller, which controls the motor to stop rotating. Then, the bolt is passed through the threaded hole of the base plate and the connection hole 10 in the fastening block of the fastening component 43 to achieve the connection between the base plate and the fastening component 43, that is, to achieve the fixed installation of the tower foot in the support mechanism 4.

[0068] Furthermore, the fastening assembly 43 includes a second slider and a fastening block; the second slider is threaded to both sides of the second lead screw, and the fastening block is connected above the second slider, and the fastening block does not extend beyond the top of the second slide groove 9; the fastening block has a connection hole 10 on the side facing the opening of the second slide groove 9 for connecting with the base plate of the tower foot.

[0069] In a preferred embodiment, the base 2 is also connected to a support platform 14, which is connected outside the frame and used to store the tower legs. For example... Figure 2 As shown, a support platform 14 is also connected to one side of the base 2. The support platform 14 is independent of the outside of the frame 22 and is used to place the next tower leg to be welded or to temporarily place the previous completed tower leg, so as to achieve the function of temporary placement.
