Description

Technical Field

[0001] The invention relates to the technical field of off-line busbar fixing, and in particular to an off-line busbar anti-displacement and anti-deformation welding fixing device. Background Art

[0002] In power transmission systems, busbars are widely used as important conductive elements. Especially in high-voltage and high-current applications, the connection quality of the busbar directly affects the safety and stability of the power system. When welding traditional offline busbars, due to the lack of effective fixing measures at the welding parts, it is easy to cause displacement or deformation at the connection, thus affecting the welding quality. In addition, once the phase-separated busbar is welded and put into use, if the welding parts are not well supported, the welding points may gradually loosen or deform over time and under the action of external forces, thus causing safety hazards.

[0003] Therefore, there is an urgent need for a device that can ensure the stability of the connection parts during the offline busbar welding process and can still provide stable support for the welding points after the busbar is put into use. In response to this demand, the present invention proposes an offline busbar anti-displacement and anti-deformation welding fixing device, which aims to solve the problems existing in the prior art. Summary of the invention

[0004] The present invention aims to provide an off-line busbar anti-displacement and anti-deformation welding fixing device to solve the problem that the connection of the existing off-phase busbar is unstable and displaced during welding, and the welding is not firm enough, which makes the off-phase busbar easily deformed.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a welding fixing device for preventing displacement and deformation of an offline busbar, comprising a first fixing ring and a second fixing ring, the first fixing ring and the second fixing ring are both open, one side of the first fixing ring is connected to a welding ring, a plurality of through grooves are provided on the welding ring, and fixing blocks are provided between adjacent through grooves, and one side of the second fixing ring is connected to a mating block detachably connected to the fixing block.

[0006] The working principle of the present invention is as follows: the two ends of the two isolated phase busbars to be welded are respectively sleeved with the first fixing ring and the second fixing ring. After the first fixing ring and the second fixing ring are fixed, a crane is used to move the isolated phase busbar connected to the second fixing ring close to the first fixing ring. After the two isolated phase busbars are aligned, a plurality of matching blocks are connected to the fixing blocks. At this time, the two isolated phase busbars to be welded are located on the same horizontal line, and the connection to be welded is located at the through groove. A welding device is used to start welding from the through groove. After most of the welding is completed, the matching blocks and the fixing blocks are separated, and the remaining unwelded parts are continued to be completed.

[0007] Furthermore, the fixing block is a plurality of fixing rods, the welding ring is provided with a plurality of recessed blocks, the recessed blocks are located between adjacent through grooves, a plurality of fixing rods are connected in the recessed blocks, the matching block is a rotating plate, one end of the rotating plate is connected to the second fixing ring, the other end of the rotating plate is connected to an inclined block, a circular groove corresponding to the position of the fixing rod is provided on the rotating plate, and a plurality of inclined grooves are provided on the outer wall of the second fixing ring, the shape of the inclined grooves is consistent with the inclined block. During operation, the rotating plate passes through the bottom of the recessed block, and after passing through, the rotating plate is rotated clockwise so that the circular groove fits tightly with the fixing rod, and the inclined block is inserted into the inclined groove at this time, and the fixing is completed and welding can be started.

[0008] Furthermore, the openings of the first fixing ring and the second fixing ring are connected with connecting pieces, and the connecting pieces are connected to the first fixing ring and the second fixing ring by screws. The first fixing ring and the second fixing ring can be fixed on the phase-isolated busbar by setting the screws.

[0009] Furthermore, the bottom end of the second fixing ring is connected with an alignment plate. Through the arrangement of the alignment plate, when the second fixing ring corresponds to the first fixing ring, the alignment plate can be quickly aligned with the welding ring.

[0010] Furthermore, the width of the through slot is greater than the diameter of the welding gun head. By setting the width of the through slot, welding operations can be performed at the through slot.

[0011] Furthermore, the diameter of the welding ring is larger than that of the first fixing ring. By setting the diameter of the welding ring, the welding ring can block a small part of the flying sparks during welding operation.

[0012] The beneficial effects of the present invention are as follows: 1. During the welding process, the design of the fixing ring and the welding ring ensures the stability of the phase-isolated busbar during welding, effectively preventing the phase-isolated busbar from being displaced or deformed during welding, thereby improving the quality and reliability of welding; 2. The detachable connection method of the rotating plate and the fixing rod not only facilitates the installation and disassembly of the device, but also allows the welding operation to be carried out smoothly at the through groove, thereby improving the welding efficiency; 3. The design that the welding ring has a larger diameter than the first fixing ring helps to block some of the flying sparks during the welding operation, thereby protecting the equipment or materials near the welding area from damage.

After the first fixing ring 1 and the second fixing ring 6 are fixed, a crane is used to move the phase-separated busbar connected to the second fixing ring 6 close to the first fixing ring 1. After the two phase-separated busbars are aligned, the rotating plate 5 is passed through the bottom of the concave block.
