Hereinafter, a tool for disassembling and transferring a low-voltage bushing of a large transformer according to an embodiment of the present application will be described in detail with reference to fig. 1 to 8. It is noted that the following examples are merely for explaining the present application and are not to be construed as limiting the present application.
Example 1:
as shown in fig. 1, a tool for disassembling and transferring a low-voltage bushing of a large-sized transformer includes: the frame is arranged around the low-voltage sleeve and fixedly connected with the flange of the low-voltage sleeve; the screw rod component penetrates through the frame, and the low-voltage sleeve can be lifted and transported through the screw rod component.
The metal frames are assembled together through bolts, and are stressed through threaded holes and bolt holes on the low-pressure sleeve flange; meanwhile, a screw rod is arranged on the metal frame, and a caster wheel is arranged below the screw rod. The metal frame on the periphery of the sleeve not only can protect the sleeve, but also can bear the load of the sleeve in the installation and transportation processes.
Referring to fig. 2-4, the frame includes square metal frame 1 and side metal frame 2, square metal frame is trapezoidal and has two, sets up in low pressure sleeve pipe both sides respectively, side metal frame has 4, connects the upper and lower both sides of two square metal frames respectively and forms a whole frame, the top of side metal frame is equipped with 4 eye bolts. They are assembled around the low-voltage bushing 12 by means of metal frame fixing bolts 5, eye bolts 6. The middle position of the bottom of the square metal frame is provided with a bolt hole which is fixed with the low-pressure sleeve flange through a sleeve bearing bolt.
In some embodiments, the frame further comprises: the device comprises a pull plate A8, a pull plate B9 and a bolt tensioner 7, wherein the pull plate A and the pull plate B are fixed with a flange of a low-voltage sleeve through pull plate fixing bolts; the bottom of the lateral metal frame at the lower side is provided with an open-pore pulling plate which is connected with the pulling plate A through a bolt tensioner. The two ends of the bolt tensioner are locked by the pin 7-1.
In some embodiments, the screw rod component comprises a screw rod 3, a hexagonal head metal block, a screw rod nut and a universal castor 4, wherein the screw rod is provided with four screw rods which respectively penetrate through the lateral metal frames, the bottom of the screw rod is fixedly connected with a rotating plate on the universal castor, the screw rod nut is in threaded connection with the screw rod, the screw rod nut is respectively arranged on the lateral metal frames, and the hexagonal head metal block is arranged at the top of the screw rod.
The working process is as follows, as shown in fig. 5, by installing the square metal frame 1 and the side metal frame 2 around the low-voltage sleeve 12, the sleeve bearing bolt 11 and the bolt tensioner 7 are utilized, and the pull plate A8 and the pull plate B9 are used for hanging the low-voltage sleeve 12 in the vertical direction. The hexagonal head metal block 3-1 at the top of the screw rod 3 is rotated by a wrench, so that the displacement of the low-voltage sleeve 12 in the vertical direction can be realized; the low-voltage bushing 12 can be lifted by means of four eye bolts 6.
