The invention belongs to the technical field of electric power construction, and particularly relates to a rotary welding platform for electric power construction.
Background
The tower tube or lightning rod in the power infrastructure is formed by connecting a plurality of sections of steel tubes, and the plurality of sections of steel tubes are welded together section by section in a manual welding mode at present. When welding steel pipes, in order to ensure the alignment of the steel pipes, workers mostly place the steel pipes on the ground, and the steel pipes are required to be continuously rolled in the welding process so as to be welded by 360 degrees along the circumferential direction. Therefore, the multi-person cooperation operation is needed, a welder also needs to bend over to weld, the labor intensity is high, and the welding is inconvenient. If the components influencing rolling on the steel pipe or the steel pipe has large weight and volume and is difficult to roll, the circumferential welding is difficult to be carried out in a mode of rolling on the ground. Therefore, a way to lift the steel pipe and drive the steel pipe to rotate is needed, which is convenient for the worker to perform circumferential welding.
For example, patent document CN214161964U proposes a rotatable steel tube welding support, which includes a support body, the support body includes a first support frame and a second support frame symmetrically disposed, the first support frame and the second support frame are connected by at least one transverse connecting rod, and the transverse connecting rod is provided with at least one rolling component capable of rotating relative to the transverse connecting rod; the lower ends of the first support frame and the second support frame are both provided with a support leg rod, and the first support frame and the second support frame are both of arc-shaped structures with upward openings. This patent can realize the supplementary welding to the steel pipe, is convenient for overturn it when the pipeline welds, and the adjustment steel pipe angle welds the different positions of steel pipe.
For another example, patent document CN106363339A proposes a fixed-distance moving rotary power tower-pipe welding system, which includes a rotary clamping device, a fixed-distance moving device, a track and a welding device; the rotary clamping device comprises a rotary power mechanism, a clamping mechanism, a synchronous rotary transmission mechanism, a rear clamping rotary mounting mechanism and a rotary fixing frame; the welding device is positioned on one side of a gap between the rotary power mechanism and the rear clamping rotary mounting mechanism; the distance moving driving mechanism can move along the track and is arranged on the track behind the rotary clamping device. The control system clamps and fixes the front and rear sections of tower pipes through the front clamping mechanism and the rear clamping mechanism, and adjusts the distance of a welding seam between the welding gun mechanism and the front and rear sections of tower pipes through the welding height adjusting mechanism; after the welding distance is adjusted properly, a welding gun is started, and a rotary driving motor is started, so that the rotary clamping device drives the front tower tube and the rear tower tube to synchronously rotate, and the welding gun can completely weld the gap between the front tower tube and the rear tower tube in the rotating process.
The above patent documents are applicable to welding of steel pipes of the same diameter, but for steel pipes of different diameters, the alignment of the central axes of the two is ensured before welding, but with the above patent documents, the alignment of the central axes of the steel pipes of different diameters cannot be achieved.

The lifting driving mechanism comprises a motor bin, a lifting driving motor, a lifting speed reducing mechanism, a lead screw and a control button;
the motor bin is arranged at the bottom of the supporting rod;
the lifting driving motor and the lifting speed reducing mechanism are both arranged in the motor bin, the lifting speed reducing mechanism is connected with the lifting driving motor, and an output shaft is vertically upward;
the screw rod is vertically arranged, the bottom end of the screw rod is fixedly connected with an output shaft of the lifting speed reducing mechanism, and the upper part of the screw rod extends into the supporting rod and then is in threaded connection with the lifting rod;
the control button is used for controlling the forward rotation, the reverse rotation and the stop of the lifting driving motor;
the lifting driving motor and the control button are electrically connected with the control box.
Further, the measuring device also comprises a scale mechanism, wherein the scale mechanism comprises a graduated scale and a measuring rod;
the graduated scale is a cylindrical rod and is vertically arranged, and the bottom end of the graduated scale is fixedly connected with the sliding block;
the measuring rod is horizontally arranged, one end of the measuring rod is movably connected with the graduated scale, and the measuring rod can slide and rotate up and down along the graduated scale;
and scale marks for marking the diameter of the cylindrical rod in the object placing groove are arranged on the rod body of the graduated scale.
Further, a distance measuring circuit is arranged in the scale mechanism and electrically connected with the control box and used for acquiring the diameter of the cylindrical rod in the object placing groove.
Furthermore, two groups of rotary welding platforms are arranged and used for continuously welding the two cylindrical rods.
Furthermore, the control boxes of the two groups of rotary welding platforms are electrically connected;
the rotary welding platform has a height calibration function and is used for aligning the central axes of two cylindrical rods to be welded;
the rotary welding platform has a rotating speed synchronization function and is used for enabling two cylindrical rods to be welded to have the same rotating speed.
The continuous connection of the cylindrical rods in the power construction often adopts a welding mode, and the central axes of two cylindrical rods to be welded must be aligned during welding. The two cylindrical rods with the same diameter can be conveniently welded on the ground by adopting an auxiliary welding means such as patent documents CN214161964U and CN 106363339A.
However, it is difficult to align the central axes of two cylindrical rods with different diameters. For example, when the welding machine is placed on the ground for welding, a thin cylindrical rod support needs to be fixed to a proper height, so that a support with a proper height needs to be selected, and errors are easily caused during manual alignment, and the quality of a finished product is affected.
In order to align two cylindrical rods, two concentric circular clamps are provided, and the clamps can fix the cylindrical rods at the central axes thereof, as in patent documents CN113210997A and CN112824010A, a similar method is adopted. However, the welded cylindrical rod of this method needs to be extracted from the clamp, for example, some longer or heavier cylindrical rods, are difficult to extract, and are easy to collide with the clamp during extraction to cause damage to the two.
It is convenient if the welded cylindrical rod can be directly lifted off the welding platform, but the method is rarely adopted in the prior art. On one hand, the method requires that the upper part of the cylindrical rod is free of blocking, so that the cylindrical rod can be supported only in a bottom supporting mode, and meanwhile, in order to realize the alignment of the cylindrical rods with different diameters, the horizontal height of the cylindrical rod needs to be adjusted.
On the other hand, the cylindrical rods need to rotate to carry out circumferential welding, and the rotating speeds of the two cylindrical rods need to be consistent; in the case of the supported cylindrical rods, the force (friction force) for driving the rotation is applied to the lower surface only when the supported cylindrical rods are driven to rotate, and if the diameters of the two cylindrical rods are different, the rotation speed of the rotation source for driving the cylindrical rods to rotate cannot be the same in order to make the rotation speeds of the two cylindrical rods consistent. Although there are patent documents CN212918300U and CN208322590U, etc. which use spot welding to primarily weld and fix two cylindrical rods, and then drive one cylindrical rod to rotate, i.e. drive the other cylindrical rod to rotate synchronously, such discontinuous welding mode will affect the welding quality.
Under the circumstances, the inventor of the present invention has studied and found that the height adjusted for aligning the cylindrical rod and the rotational speed of the power source for aligning the rotational speed of the cylindrical rod are directly related to the diameter of the cylindrical rod, and therefore, the present invention first automatically obtains the diameter of the cylindrical rod, automatically performs height calibration based on the diameter to align the central axes of the cylindrical rods, and automatically performs rotational speed synchronization to bring the cylindrical rods to have the same rotational speed.
Compared with the prior art, the invention has the following beneficial effects:
the invention can drive the cylindrical rod to rotate, thereby facilitating the circumferential welding of workers; when the welding device is arranged independently, the welding device can be suitable for welding objects such as cylindrical rods, flange plates and the like, and when the welding device is arranged in groups, the welding device can be suitable for continuously welding two cylindrical rods.
According to the invention, the cylindrical rod to be welded is driven to rotate in an electric mode, and the pedal switch is arranged, so that a worker can control the rotation and the rotating speed of the cylindrical rod in a pedal mode, and the welding operation can be conveniently performed by liberating two hands; the invention is also provided with a speed regulation knob, and the rotating speed of the cylindrical rod can be conveniently regulated and set. The invention is provided with the lifting frame, the height of the lifting frame can be adjusted manually or electrically, and the lifting frame is also provided with the sliding rail and the sliding block, so that the position of the object to be welded can be adjusted leftwards and rightwards, therefore, the lifting frame can adjust the object to be welded to a proper welding position, and is convenient for workers to weld.
The invention can be suitable for continuous welding of cylindrical rods with different diameters, when the height of one group of welding platforms is adjusted, the other group of welding platforms can automatically and synchronously adjust the height, and the two cylindrical rods after the height adjustment can automatically align to the central axis; when one group of welding platforms is controlled to rotate the cylindrical rods for welding, the other group of welding platforms can synchronously realize the rotation of the other cylindrical rods, the rotating speeds of the two cylindrical rods can be kept consistent, and the dislocation of the welding position is ensured not to occur.
The welding operation can be completed by a single person, the bending operation is not needed in the welding process, and the cylindrical rod does not need to be manually rotated, so that the labor intensity can be greatly reduced, and the working efficiency is improved.
