Description

Technical Field

[0001] The utility model relates to the field of transformer production and manufacturing, in particular to a sandblasting and painting workstation for a transformer oil tank. Background Art

[0002] The transformer oil tank is a vital component of the transformer. Its functions include: containing transformer oil, providing insulation and cooling for the transformer's core and windings; protecting internal components from foreign matter and moisture that could affect normal operation; and helping to dissipate heat generated by the transformer during operation, maintaining a suitable operating temperature. Therefore, the design and manufacturing quality of the transformer oil tank have a significant impact on the transformer's performance and safe operation.

[0003] Existing transformer fuel tank production typically involves cutting, assembly, welding, sandblasting, painting, and inspection. Cutting involves cutting materials according to the dimensions and materials specified in the drawings. Assembly involves assembling and assembling the tanks according to the dimensions in the drawings. Welding involves welding the assembled tanks together. The welds must be uniform and full, with no sand holes. After welding, the tanks must be polished cleanly. Sandblasting involves treating the tank surface to improve adhesion for the subsequent painting process. Painting involves applying functional paint, such as anti-corrosion paint, to the tank surface. However, in actual manufacturing, sandblasting and painting are performed at different locations within the workstation. After sandblasting, the tanks must be transported to the paint booth, and then to the drying room. Existing workstations often rely on manual transport, but large transformer fuel tanks are large and heavy, making manual transport labor-intensive and inefficient.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Summary of the Invention

[0005] To improve or resolve the technical issues of high labor intensity and low transfer efficiency in the prior art manual transfer, the present invention provides a sandblasting and painting workstation for transformer oil tanks. The sandblasting and painting workstation for transformer oil tanks comprises: a plurality of processing chambers arranged side by side; a track comprising a conveyor track connected to the plurality of processing chambers and a transfer track connected to the conveyor track; each conveyor track is connected to a corresponding processing chamber; a track vehicle movably arranged on the track; the track vehicle comprises a frame, a conveyor running device compatible with the conveyor track, and a transfer running device compatible with the transfer track; a lifting device is provided between the transfer running device and the frame, the lifting device being configured to drive the transfer running device up and down to disengage or engage with the transfer track.

[0006] The utility model discloses a sandblasting and painting workstation for transformer oil tanks, comprising a processing chamber, tracks, and a railcar. The processing chamber is used for painting, sandblasting, and drying the transformer oil tanks. The tracks include a conveyor track and a transfer track. The conveyor track is connected to the processing chamber and is used to transport the transformer oil tanks into the processing chamber. The transfer track is connected to the conveyor track and is used to transfer the transformer oil tanks from one conveyor track to another conveyor track, thereby enabling the transfer of the transformer oil tanks. The railcar is arranged on the tracks in a movable manner and includes a frame, a conveyor running device, a transfer running device, and a lifting device. The frame supports the transformer oil tanks. The conveyor running device is compatible with the conveyor track and can travel on the conveyor track. The transfer running device is compatible with the transfer track and can travel on the transfer track. The lifting device is arranged between the frame and the transfer running device and can drive the frame up and down. The transfer running device cooperates with the transfer track. When it is necessary to switch to the conveyor running track, the lifting device drives the frame down, and the conveyor running device then descends and cooperates with the conveyor running track until the transfer running device is suspended in the air. Through the above-mentioned arrangement, the utility model is used for the sandblasting and painting workstation of the transformer oil tank. By setting tracks and rail cars, the transformer oil tank can be more conveniently transported in the processes of sandblasting, painting, drying, etc., thereby improving the transport efficiency and reducing the labor intensity of workers.

Through the above arrangement, the motor drives the wheels to rotate, which can more conveniently drive the motor to rotate.

[0009] In the preferred technical solution of the sandblasting and painting workstation for transformer tanks, the conveyor track and the transfer track are arranged in a cross configuration. A bracket suitable for supporting the transformer tank is provided at the end of the conveyor track away from the processing chamber. This arrangement allows the bracket to be pre-positioned at one end of the conveyor track to support the transformer tank, thereby facilitating loading and unloading of the railcar and the transformer tank.

[0010] In the preferred technical solution of the sandblasting and painting workstation for transformer tanks, the bracket includes a frame suitable for supporting the transformer tank and legs mounted at the bottom of the frame. The above arrangement of the legs facilitates the movement of the railcar to the bottom of the frame.

[0011] In the preferred technical solution of the sandblasting and painting workstation for transformer tanks, a cushion is provided on the frame. This cushion is provided on the frame to support the transformer tank, increasing the contact area between the transformer tank and the bracket, and preventing the protruding structure below the transformer tank from deforming and damaging the bracket.

[0012] In the preferred technical solution of the sandblasting and painting workstation for transformer oil tanks, a lifting device for lifting the bracket is provided on the top of the frame. Through the above arrangement, the lifting device is used to lift the bracket, thereby driving the bracket to move.

[0013] In the preferred technical solution of the sandblasting and painting workstation for transformer oil tanks, a positioning device is arranged on the railcar. Through the above arrangement, the positioning device is used to locate the position of the railcar, thereby facilitating the control of the railcar's movement and track changing.

[0014] The preferred technical solution of the sandblasting and painting workstation for transformer oil tanks further includes a collision prevention device comprising a photoelectric transmitter mounted on the railcar and a reflector mounted at the end of the track. The photoelectric transmitter is configured to emit and receive light, and when the light is blocked, it stops the railcar and generates an alarm. This arrangement prevents the railcar from colliding with obstacles or pedestrians. BRIEF DESCRIPTION OF THE DRAWINGS
