Description

Technical Field

[0001] The utility model relates to the technical field of transformer maintenance, in particular to a hoisting tool suitable for a main transformer reactor cooler. Background Art

[0002] When inspecting and repairing a large indoor transformer, it is necessary to dismantle the cooler of the reactor. Since it is located indoors and the installation location may be small, it cannot be hoisted using a crane or other lifting equipment. Usually, a lifting point is set on the roof for hoisting. However, the lifting point is usually set on the top of the factory building, and the setting of the lifting point and the installation of the lifting equipment are extremely inconvenient. In addition, there are usually six reactor coolers, which are closely arranged together. If the lifting rope is too long, the cooler is easy to shake during the hoisting process and easily collide with the adjacent cooler. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a hoisting tool suitable for a main transformer reactor cooler, a gantry is arranged on the ground for hoisting, and the coolers can be hoisted out one by one.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a lifting tool suitable for the main transformer reactor cooler, including two cross beams, both of which are arranged on the bracket, a sliding frame is provided between the two cross beams, a longitudinal beam is provided on the sliding frame, a first slider is slidably connected to the longitudinal beam, and a lifting device for lifting the cooler is connected below the first slider.

[0005] Preferably, second sliding blocks are provided at the four corners of the sliding frame, and the second sliding blocks are slidably connected to the crossbeam.

[0006] Preferably, the bracket includes a fixed part and a telescopic part, the telescopic part is sleeved in the fixed part, an adjustment hole is provided on the telescopic part, and a limiting bolt matched with the adjustment hole is provided on the fixed part.

[0007] Preferably, diagonal braces are provided on both sides of the fixing portion, and a reinforcing rod is provided between the diagonal braces and the fixing portion.

[0008] Preferably, both ends of the cross beam are provided with limit stops for preventing the second sliding block from sliding out.

[0009] Preferably, the crossbeam spans six air coolers.

[0010] The utility model provides a hoisting tool suitable for a main transformer reactor cooler. It does not require high-altitude work, and the hoisting device can be set up on the ground. During hoisting, not only can the cooler be hoisted upward, but the cooler can also be moved horizontally out after hoisting, which greatly saves time and improves safety.

[0016] like Figure 1-3 As shown, a hoisting tool suitable for a main transformer reactor cooler comprises two cross beams 1, both of which are arranged on a bracket, a sliding frame 2 is arranged between the two cross beams 1, a longitudinal beam 3 is arranged on the sliding frame 2, a first slider 4 is slidably connected to the longitudinal beam 3, and a hoisting device 5 for hoisting the cooler is connected below the first slider 4. During hoisting, the sliding frame 2 is moved to achieve lateral adjustment, and the first slider 4 is moved to achieve longitudinal adjustment.

[0017] Preferably, second sliding blocks 6 are provided at the four corners of the sliding frame 2 , and the second sliding blocks 6 are slidably connected to the crossbeam 1 .

[0018] Preferably, the bracket includes a fixed portion 7 and a telescopic portion 8, the telescopic portion 8 is sleeved in the fixed portion 7, an adjustment hole 9 is provided on the telescopic portion 8, and a limit bolt 10 matched with the adjustment hole is provided on the fixed portion 7. By adjusting the height of the bracket, it can adapt to coolers of different specifications.

[0019] Preferably, diagonal braces 11 are provided on both sides of the fixing portion 7, and a reinforcing rod 12 is provided between the diagonal braces 11 and the fixing portion 7. The diagonal braces can prevent rollover and increase the firmness of the device.

[0020] Preferably, both ends of the crossbeam 1 are provided with limit stops 13 for preventing the second sliding block 6 from sliding out.

[0021] Preferably, the crossbeam 1 spans six air coolers.

[0022] When in use, set up the bracket and beam on site, then install the longitudinal beam and lifting equipment. After installation, the lifting operation can be carried out. When lifting, first lift vertically, then slide out horizontally. Figure 4 As shown, the disassembly of a single cooler can be completed, and the disassembly of each cooler can be completed one by one.
