Furthermore, the cable protection pipe on the mechanism box comprises a fixed protection pipe part and a movable protection pipe part in a segmented design, the diameter of the fixed protection pipe is larger than that of the movable protection pipe, the fixed protection pipe is welded and fixed on the mechanism box, the upper end of the lower movable protection pipe is movably inserted into the upper fixed protection pipe, and the joint of the upper fixed protection pipe and the lower movable protection pipe forms long-section superposition.
Furthermore, an inclined support frame is arranged between the horizontal part of the galvanized round steel and the equipment foundation, and the inclined support frame, the galvanized round steel and the equipment foundation form a triangular support.
Further, be equipped with the annular of concave yield on the cable protection pipe, the head end of galvanized round steel be equipped with an staple bolt, this staple bolt cover is in the annular, blocks cable protection pipe and prevents it and sink.
The bottom of the buried pipe of the cable protection pipe is fixed through the foundation buried part, so that the influence of field settlement on the buried pipe of the equipment is effectively prevented, and meanwhile, the damage of a secondary line in the buried pipe is avoided through the matching of the buried pipe of the lower opening of the mechanism box and the sheath, and the safe operation of the equipment can be guaranteed.
Drawings
FIG. 1 is a schematic view of the present invention;
fig. 2 is a schematic structural view of an embodiment of the cable protection tube in the present solution;
the device comprises a mechanism box 1, a stand column 2, an equipment foundation 3, a cross frame 4, an isolating switch 5, a cable protection tube 6, a galvanized steel plate 7, galvanized round steel 8, a fixed protection tube 9, a movable protection tube 10, a support frame 11 and a hoop 12.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1-2, the utility model provides a protection architecture is prevented subsiding by isolator mechanism case, mechanism case 1 install on stand 2, stand 2 installs on pre-buried equipment foundation 3, the top of stand 2 is provided with crossbearer 4, isolator 5 group installs on crossbearer 4, isolator 5 is controlled to every operating device case 1, operating device case 1 bottom be provided with many steel cable protection pipe 6, this cable protection pipe 6 buries the underground, the galvanized steel sheet 7 of a pre-buried vertical setting in equipment foundation 3 draws forth a galvanized round steel that has the level setting of length from galvanized steel sheet 7, this galvanized round steel and 6 welded fastening of cable protection pipe.
200x200mm galvanized steel sheets 7 are pre-buried in the construction of an equipment foundation 3 on site, after the assembly of 5 equipment of the isolating switch is completed, a cable protection sleeve and a cable fixing piece of a wire hole of the operating mechanism box 1 are additionally arranged at the bottom of the operating mechanism box 1, the cable protection pipe 6 is fixed with the operating mechanism box 1, and phi 12 hot galvanized round steel 8 is welded on the pre-buried piece and used for fixing the cable protection pipe 6. The round steel is fixed with the equipment foundation 3 in a matched mode, the cable protection pipe 6 is fixed, and sinking of the cable protection pipe is prevented.
As the improvement of the scheme, the cable protection pipe 6 on the mechanism box 1 comprises a fixed protection pipe 9 part and a movable protection pipe 10 part in a sectional design, the diameter of the fixed protection pipe 9 is larger than that of the movable protection pipe 10, the fixed protection pipe 9 is welded and fixed on the structure box, the upper end of the lower movable protection pipe 10 is movably inserted into the upper fixed protection pipe 9, and the joint of the upper fixed protection pipe and the lower movable protection pipe forms long-section superposition.
