FIG. 2 is a schematic structural view of a ball nut, wherein A is a plan view and B is a side view;
FIG. 3 is a schematic diagram of an embodiment.
Detailed Description
The technical solutions of the present invention will be described in further detail with reference to the accompanying drawings and the detailed description.
Referring to fig. 1, the overhauling and hoisting device for the modules in the electric cabinet comprises a C-shaped rail 1, a ball nut 2 and a hoisting device 3, wherein the C-shaped rail 1 is fixed at the top of the electric cabinet through a bolt, the ball nut 2 is clamped in a groove of the C-shaped rail 1, and the hoisting device 3 is in threaded connection with the ball nut 2.
The hanging device 3 can be a hook or a hanging ring according to the field requirement.
As shown in fig. 2, the ball nut 2 is composed of a nut body 4, a ball 5 and a thread 6, wherein the ball 5 is connected with the nut body 4, and the thread 6 is matched with the hanging device 3.
The nut body 4 is made of high-strength steel.
The operation method of the overhauling and hoisting device for the module in the electric control cabinet comprises the following steps:
and 6, moving up and down, and realizing up-and-down displacement movement through a chain block or a hanging strip.
Referring to fig. 3, this embodiment is an application of the shield tunneling machine up-conversion system, and is used for the maintenance and repair of the frequency converter. Because the inner space of the shield machine is limited, the frequency converter can only be assembled and disassembled from the front. The space in the cabinet is very narrow, and the high-power frequency converter is heavy, so that the operation is difficult only by manpower. The invention solves the problem well.
Firstly, the hoisting device 7 is fixed on the top of the electrical cabinet 10 through a nut, then two ends of the hanging strip 8 are hung at the hoisting position of the frequency converter 9, the middle end of the hanging strip 8 is hung on a chain block of the hoisting device 7, and the vertical displacement of the frequency converter 9 is controlled through the chain block. The front and back displacement is realized by dragging the frequency converter 9 or the hanging strip. The ball nut greatly reduces the front and back displacement friction, so that the ball nut can be smoothly pulled out of the electric cabinet.
The above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, and any simple modifications or equivalent substitutions of the technical solutions that can be obviously obtained by those skilled in the art within the technical scope of the present invention are within the scope of the present invention.
