Description

Technical Field

[0001] The invention relates to the technical field of iron tower rod welding, in particular to a welding mechanism for self-stabilizing iron tower surface rods. Background Art

[0002] The tower surface rods mainly include main materials, diagonal materials, cross partitions and auxiliary materials. These rods play different roles in the tower structure. Generally, the main materials are assembled and welded to form the main structure of the tower, while the diagonal materials and cross partitions enhance the strength of the iron scaffolding. At the same time, some auxiliary materials are welded to facilitate the installation and bearing of power transmission equipment. Different auxiliary materials need to be welded to the surface rods before installation to avoid the progress affected by on-site construction. Due to differences in diameter and length, the stability of such rods needs to be ensured during welding operations to avoid dislocation during the welding process.

[0003] The invention with announcement number CN115533398B discloses an automated welding device for the feet of a power transmission line tower, which can automatically adjust the various angles of the welding head to achieve welding of tower feet of different models. During the angle adjustment process, stability is achieved. At the same time, with the use of inert gas, the welding quality is improved.

[0004] The utility model with announcement number CN206912557U discloses a new welding device for iron tower iron accessories. By rotating the two fourth gears between the two support columns, the sawtooth bar can be moved up and down, thereby driving the ventilation pipe and the welding head thereon to move up and down. By rotating the third gear, the second gear and the welding head fixedly connected thereto can be rotatable. In this way, the movement of the welding head in three-dimensional space and the rotation of the welding head can be realized, which can meet the welding needs of different workstations.

[0005] However, the above-mentioned welding device for tower rods still has the following problems during actual use: although the welding of the rods is achieved through a welding gun head with an adjustable angle, the rods welded by this type of welding device have different diameters and lengths, and most of them are columnar structures. Therefore, the rods cannot be locked and positioned during the welding process, which easily causes the rods to be offset and misaligned during welding. At the same time, the welding position cannot be adjusted, which reduces the efficiency of the welding operation.

[0006] Therefore, we proposed a self-stabilizing tower surface rod welding mechanism to solve the above-mentioned problems. Summary of the invention

[0007] The purpose of the present invention is to provide a self-stabilizing tower surface rod welding mechanism to solve the problem that the existing welding work of the rods is achieved by using a welding gun head with an adjustable angle. However, the rods welded by this type of welding device have different diameters and lengths, and most of them are columnar structures. Therefore, the rods cannot be locked and positioned during the welding process, which easily causes the rods to be offset and misaligned during welding. At the same time, the welding direction cannot be adjusted, which reduces the efficiency of the welding operation.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a self-stabilizing tower surface rod welding mechanism, comprising a bearing base, and support linings fixedly installed on the left and right sides of the rear of the top surface of the bearing base, and the top ends of the symmetrically arranged support linings slide through the interior of the positioning ring body; and further comprising:

[0009] A positioning mechanism is arranged inside the bearing base, and the positioning mechanism includes a driving bevel gear ring, and a transmission bevel gear is arranged on the outer side of the driving bevel gear ring in an equiangular meshing manner;

[0010] Among them, a distance adjustment mechanism is arranged above the bearing base, and the distance adjustment mechanism includes a cross bracket, and an anti-dropout slider is fixedly arranged on the bottom surface of the outer end of the cross bracket, and the anti-dropout slider is slidably engaged with the inside of the positioning ring body.

[0011] Preferably, the positioning mechanism includes a positioning sleeve, and the positioning sleeve is fixedly installed inside the transmission bevel gears arranged at equal angles, and the insides of the positioning sleeves arranged at equal angles are all threadedly connected to the outer ends of the positioning screws.

[0012] Preferably, the outer end of the positioning screw included in the positioning mechanism slides through the inner outside of the supporting base, and the inner end horizontal height of the positioning screw arranged at equal angles is higher than the top surface horizontal height of the supporting base, so that the positioning screw can slide inward and outward directions.

[0013] Preferably, the positioning mechanism includes a guide slider, and the guide slider is fixedly mounted on the inner end of a positioning screw arranged at an equal angle, and the inner part of the guide slider elastically slides on the outer end of the top surface of the floating locator, and the bottom surface of the floating locator slides in contact with the bottom surface of the supporting base.

[0014] Preferably, the distance adjustment mechanism includes a telescopic slide rod, and the connection of the telescopic slide rod is a concave-convex structure to achieve sliding and engaging rotation, and the top end of the telescopic slide rod is rotated to the anti-slip slider arranged on the bottom surface of the cross bracket, and the top ends of the symmetrically arranged telescopic slide rods are engaged with each other through a sprocket mechanism.

[0015] Preferably, the distance adjusting mechanism includes a guide gear, and the guide gear is fixedly installed on the bottom ends of the telescopic slide rods on the left and right sides, and the distance adjusting mechanism includes a guide tooth block, and the guide tooth block is fixedly installed inside the supporting base, and the guide gear and the guide tooth block are meshingly connected.

[0016] Preferably, the distance adjusting mechanism includes a lifting threaded rod, and the bottom end of the lifting threaded rod is rotatably arranged behind the top surface of the supporting base, and the top thread of the lifting threaded rod passes through the rear interior of the positioning ring body, and a lifting slide rod is arranged behind the supporting base, and the top end of the lifting slide rod is connected to the lifting threaded rod.

[0017] Preferably, a welding mechanism is provided on the bottom surface of the cross bracket, and the welding mechanism includes a bidirectional screw and a guide screw, and the bidirectional screw and the guide screw are rotatably arranged on the bottom surface of the cross bracket through bearings, and the middle part of the bidirectional screw is meshed and connected to the inner end of the bidirectional screw through a bevel gear group.

[0018] Preferably, the welding mechanism includes a welder body, and the welder body is threadedly connected to the outer walls of the guide screws on the left and right sides of the bottom surface of the cross bracket, and the front and rear sides of the bidirectional screws on the bottom surface of the cross bracket are threadedly connected to the smoke collector, and the welder body and the smoke collector are driven to move synchronously in opposite directions through the guide screw and the bidirectional screw.

[0019] Preferably, the positioning ring and cross bracket included in the distance adjustment mechanism drive the welding mechanism to adjust the welding angle and height, and the guide screw and bidirectional screw included in the welding mechanism drive the welder body and the smoke collector to adjust and adapt to the welding of rods of different specifications.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: the self-stabilizing tower surface rod welding mechanism can position rods of different shapes and specifications through the positioning mechanism inside the bearing base and the slidable floating positioner. At the same time, the distance adjustment mechanism drives the welding machine body to rise and fall and rotate, and the moving welding machine body drives the smoke collector to collect the smoke during the welding operation to avoid affecting the welding work. The specific contents are as follows:

[0021] 1. The driving bevel gear ring of the positioning mechanism meshes with the transmission bevel gear and the positioning sleeve to rotate, and the positioning screw threadedly connected to the positioning sleeve is limited by the guide slider and the floating locator at the inner end, so that the threaded positioning screw drives the guide slider and the floating locator to slide inside and outside, so as to adapt to different specifications of rods for positioning.

[0022] When positioning rods of different shapes and specifications, the floating locators will contact the rods in sequence. When some floating locators contact the rods first, the floating locators elastically connected by the guide sliders are resisted and move backwards, while the floating locators that have not contacted the rods continue to move and limit the rods after contact, thereby ensuring the stability of the rods during subsequent welding.

[0023] 2. The telescopic slide rod at the outer end of the cross bracket is meshed with each other through a sprocket mechanism, and drives the guide gear to mesh with the guide tooth block during rotation, thereby driving the telescopic slide rod and the cross bracket to rotate above the positioning ring body. At the same time, the bottom surface of the cross bracket is slidably arranged inside the positioning ring body through a fixedly connected anti-dropping slider, thereby ensuring that the cross bracket drives the welding mechanism to not be misaligned when rotating to adjust the angle.

[0024] 3. The lifting threaded rod drives the positioning ring body to be threadedly connected. At the same time, support lining plates are slidably arranged on the left and right sides of the rear of the positioning ring body, so that the lifting threaded rod drives the positioning ring body to adjust the height according to rods of different specifications. At the same time, the positioning ring body drives the welding machine mechanism to synchronously descend the welding device body and the smoke collector to the required welding height.

[0025] The bevel gear group in the middle of the bidirectional screw engages with the guide screws on the left and right sides, so that the rotating guide screw and the bidirectional screw respectively drive the welder body and the smoke collector to slide inward synchronously, and then adjust the required welding distance according to the rod. The smoke collector absorbs the smoke during the welding process to prevent dust and smoke from affecting the welding work. BRIEF DESCRIPTION OF THE DRAWINGS
