Description

Technical Field

[0001] The invention relates to the technical field of electric power equipment manufacturing, in particular to an S-bend tool balancing hanging beam which can be used for hanging the S-bend tool during transformer winding. Background Art

[0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are primary coil, secondary coil and iron core (magnetic core). Its main functions include voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. According to its use, it can be divided into: power transformer and special transformer (furnace transformer, rectifier transformer, power frequency test transformer, voltage regulator, mining transformer, audio transformer, medium frequency transformer, high frequency transformer, impact transformer, instrument transformer, electronic transformer, reactor, mutual inductor, etc.).

[0003] In the process of transformer manufacturing, in order to reduce the eddy current loss of the transformer and improve the transformer's short-circuit resistance, large transformer coils are wound with transposed conductors, and the conductors need to be folded into S-bends during the winding process. Operators carry S-bend tools to operate. For large-sized transposed conductors, the S-bend tools are relatively heavy and require two people to operate collaboratively, which is labor-intensive and has low work efficiency. Summary of the invention

[0004] In order to solve the above technical problems, the present invention discloses an S-bend tool balance hanging beam, which can be used to hang the S-bend tool during the transformer winding process.

[0005] An S-bend tool balancing suspension beam comprises a vertical rod and a horizontal beam made of steel pipes. The vertical rod is fixed on the ground. The top of the vertical rod is connected with a shaft sleeve. A vertical shaft is arranged at the connection position between the shaft sleeve and the vertical rod. A thrust ball bearing is arranged on the vertical shaft. A horizontal beam is arranged on the shaft sleeve. The horizontal beam and the shaft sleeve extend outward vertically. A rotating bearing is arranged on the top of the shaft sleeve. A pull rod is arranged around the rotating bearing and connected to the other end of the horizontal beam. A spring balancer is slidably arranged on the horizontal beam.

[0006] In the above technical solution, the entire vertical rod is fixed to the ground with anchor bolts, the crossbeam is welded to the shaft sleeve, and rotates through the bearing. The spring balancer that slides on the crossbeam adjusts the up and down distance. It is used to suspend the coil during the transformer winding process and can be removed when not in use.

[0007] A further improvement of the present invention is that a sealing plate made of steel plate is welded at the position where the crossbeam is connected to the pull rod, round steel is vertically welded on the sealing plate, and the round steel and the pull rod are welded by cutting screws with lifting eyes; a rigging knob is arranged between the pull rod and the shaft sleeve, one end of the rigging knob is connected to the shaft sleeve, and the other end is connected to the pull rod.

[0008] A further improvement of the present invention is that baffles made of steel plates are arranged on both sides of the cross beam, the baffles are fixed on the cross beam, a roller is arranged on the upper part of the sealed space formed by the baffle and the cross beam, an axis is arranged in the middle of the roller, a sliding bearing is arranged on the outer periphery of the axis, the axis extends outward to the outside of the baffle and is fixed by hexagonal bolts, a hexagonal nut is tightened outside the hexagonal bolts, a hanging shaft is arranged at the lower part of the sealed space formed by the baffle and the cross beam, both sides of the hanging shaft are tightly fixed on the inner side of the steel plate and fixed by hexagonal bolts, and the hook at the upper part of the spring balancer is hung on the hanging shaft; a flat washer set as an upper flat washer is arranged between the axis and the steel plate at the upper part of the sealed space formed by the baffle and the cross beam, and a spring washer set as an upper spring washer is also arranged on the inner side of the upper flat washer; a flat washer set as a lower flat washer is arranged between the hanging shaft and the steel plate at the lower part of the sealed space formed by the baffle and the cross beam, and a spring washer set as a lower spring washer is also arranged on the inner side of the lower flat washer.

[0009] A further improvement of the present invention is that the part of the vertical rod that contacts the ground is provided with a bottom plate made of steel plate, and a reinforcing plate made of steel plate is welded on the bottom plate along the four sides of the vertical rod. The reinforcing plate is shaped like a right triangle, and the two right-angled sides of the reinforcing plate in the shape of a right triangle are welded one to the bottom plate and the other to the vertical rod.

[0010] In the above technical solution, deep groove ball bearings can be used for both sliding bearings and rotating bearings.

[0011] Beneficial effects of the invention: The invention is an S-bend tool used for large-size transposed conductors, which adopts a mechanical pulling method to replace manual hand-held operation, thereby reducing manual labor intensity, and one person operates instead of two people.
