[0034] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0035] Embodiment 1:

[0036] See Figures 2 to 3 , a screw rod protection tooling. This embodiment is applied to the protection of the extension screw rod of the transformer oil tank elevation seat.

[0037] A screw rod protection tooling includes a first casing 1, a first partition board 2, a second partition board 3, and a fixed nut 4 for connecting the screw rod 7. The first partition board 2 and the second partition board 3 are arranged along the axial direction of the first casing 1. The plate surface of the first partition board 2 is parallel to the plate surface of the second partition board 3. Through holes for inserting the screw rod 7 are provided on both the first partition board 2 and the second partition board 3. Since the number of screw rods 7 on the transformer oil tank 8 is six, six through holes are provided on both the first partition board 2 and the second partition board 3, and the positions correspond one by one to the positions of the screw rods 7 to be protected. The first casing 1, the first partition board 2, and the second partition board 3 form a protection space for the screw rod 7. The fixed nut 4 is locked at the free end of the screw rod 7 to prevent the protection tooling from falling off, so that the protection tooling protects the screw rod 7. As Figure 3 shown, the protection tooling can be assembled on the extension screw rod 7 of the transformer oil tank 8 to protect the screw rod 7 from being deformed or damaged due to external force during transportation and production. In this embodiment, the first partition board 2 is fixedly connected to the bottom end of the first casing 1. The second partition board 3 is arranged inside the first casing 1 and can move along the axial direction of the first casing 1 to adjust the distance between the first partition board 2 and the second partition board 3, so as to realize the protection of screw rods 7 with different lengths.

[0038] See Figure 2 , slide rails 1.2 are provided on the inner wall of the first casing 1, and grooves 3.2 corresponding to the slide rails 1.2 are provided on the second partition board 3. The slide rails 1.2 are arranged along the axial direction of the first casing 1, which can realize the relative sliding between the second partition board 3 and the first casing 1, so as to adjust the distance between the first partition board 2 and the second partition board 3 and protect screw rods 7 with different lengths.

[0039] The first partition 2 is connected to the second partition 3 by a telescopic member 5. The telescopic member 5 can be a mechanism or part that can drive the second partition 3 to make a linear motion along the axial direction of the first casing 1, such as a hydraulic cylinder, a pneumatic cylinder, etc. In the present embodiment, the telescopic member 5 is a pneumatic cylinder. When the position of the second partition 3 is adjusted to a suitable position (the free end of the screw rod 7 extends out of the second partition 3 to a length that can install the fixing nut 4 and leave a margin of 5 to 10 mm), the second partition 3 can be supported by maintaining pressure through the cylinder to prevent the second partition 3 from sliding downward and causing the protective tooling to loosen. Preferably, the telescopic members 5 are evenly distributed at the bottom of the second partition 3 to ensure that the second partition 3 is evenly stressed.

[0040] The length of the first casing 1 along the axial direction thereof is greater than the length of the screw 7 to be protected, and is used to form a protective ring around the periphery of the screw 7 to prevent the screw 7 from being damaged by external factors.

[0041] The outer wall of the first casing 1 is provided with anti-slip patterns or handrails 1.3 to facilitate construction workers in carrying protective work clothes and prevent the protective work clothes from slipping from the hands of construction workers during transportation and causing safety accidents. In this embodiment, a handrail 1.3 is provided on the outer wall of the first casing 1.

[0042] The first casing 1, the first partition 2, and the second partition 3 are made of aluminum alloy or steel. When aluminum alloy is used to manufacture the protective tooling, the overall weight of the protective tooling can be reduced, and the labor intensity of workers during transportation can be reduced; when steel is used to manufacture the protective tooling, the manufacturing cost of the protective tooling can be reduced.

[0043] The method of using the above-mentioned screw protection tooling is: bring the first partition 2 into contact with the flange plate on which the screw 7 is installed on the transformer oil tank 8, so that the screw 7 passes through the first partition 2 and the second partition 3 in turn, and adjust the position of the second partition 3 manually or by sliding the telescopic member 5, so that the distance between the first partition 2 and the second partition 3 matches the length of the screw, and the free end of the screw 7 extends out of the second partition 3 by a length that can install the fixing nut 4 and leave a margin of 5 to 10 mm, and finally install the fixing nut 4 on the screw 7 to complete the connection between the protection tooling and the screw 7, and the protection tooling can protect the screw 7.

[0044] Embodiment 2:

[0045] The difference between this embodiment and embodiment 1 is that a slide groove 1.1 is provided on the inner wall of the first casing 1, and a slide tooth 3.1 corresponding to the slide groove 1.1 is provided on the second partition plate 3. Figure 4 shown.

[0046] Embodiment 3:

[0047] The difference between this embodiment and Embodiment 1 is that no sliding mechanisms such as a chute 1.1, a sliding tooth 3.1, a slide rail 1.2, and a groove 3.2 are provided between the second partition plate 3 and the first casing 1, and no telescopic member 5 is provided between the first partition plate 2 and the second partition plate 3. The screw protection tooling in this embodiment further includes a second casing 6, and the top end of the second casing 6 is connected to the second partition plate 3; the second casing 6 is movably connected to the first partition plate 2 and can move axially along the first partition plate 2 to adjust the distance between the first partition plate 2 and the second partition plate 3, so as to realize the protection of screws 7 of different lengths. At the same time, the bottom end of the second casing 6 extends into the riser of the transformer oil tank 8, and can transfer the external force received by the protection tooling to the box body of the transformer oil tank.

[0048] External threads are provided on the outer wall of the second casing 6, and internal threads corresponding to the external threads are provided on the first partition plate 2. By adjusting the threaded connection position between the second casing 6 and the first partition plate 2, the relative distance between the first partition plate 2 and the second partition plate 3 can be changed, as Figures 5 to 6 shown.

[0049] In this embodiment, relative rotation can occur between the second partition plate 3 and the first casing 1. To ensure that the through-hole positions on the first partition plate 2 and the second partition plate 3 correspond one by one, positioning members are provided on both the second partition plate 3 and the first casing 1. The positioning member can be a scale line or a groove with positioning function, etc.

[0050] The material of the second casing 6 is aluminum alloy or steel.

[0051] The using method of the screw protection tooling in Embodiment 3 is as follows: Adjust the relative distance between the first partition plate 2 and the second partition plate 3 according to the length of the screw 7, so that the length of the free end of the screw 7 extending out of the second partition plate 3 can install and fix the nut 4 with a margin of 5-10 mm. At the same time, attention should be paid to aligning the positioning members on the second partition plate 3 and the first casing 1 to ensure that the through-hole positions on the first partition plate 2 and the second partition plate 3 correspond one by one; then pass the screw 7 through the first partition plate 2 and the second partition plate 3 in sequence, and fix the free end of the screw 7 with the fixing nut 4.

[0052] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
