Description

Technical Field

[0001] This invention relates to the field of transformer maintenance technology, and in particular to a safety belt hanging rod fixing device for the maintenance of large transformer oil tanks and its usage method. Background Technology

[0002] When overhauling large transformers (such as 35kV and 110kV transformers), the work is essentially high-altitude work due to the height of their enclosures, which can be three meters or even higher. This is especially true for the transformer oil conservator, which can be two to three meters higher than the transformer enclosure itself. Figure 1 As shown, previous maintenance work involved attaching safety belts to the transformer tank or oil tank, which no longer meets the current requirement of "high mounting and low use." To meet this requirement, scaffolding or hoisting equipment must be erected. However, in mountainous photovoltaic power generation environments, due to the high altitude and long distances, hoisting equipment is difficult to access, and the cost of erecting scaffolding is relatively high. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a safety belt hanging rod fixing device and its usage method for the maintenance of oil tanks of large transformers, so as to solve the problem that the high-altitude protection work during the maintenance of oil tanks of large transformers cannot meet the "high hanging, low use" requirement.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a safety belt hanging rod fixing device for maintenance of a large transformer oil conservator, including an oil conservator and an oil pipe connecting the oil conservator and the transformer box, the oil pipe being vertically connected to the bottom of the oil conservator, including an arc plate for fitting against the arc surface of the oil conservator, a vertically upward safety belt hanging rod provided in the middle of the arc plate, a hanging ring provided at the upper end of the safety belt hanging rod, and first connecting buckles provided at both ends of the arc plate; A clamp is installed on the oil pipe, and a second connecting buckle is installed on each side of the clamp. The first connecting buckle and the second connecting buckle are set on the same side, and the first connecting buckle and the second connecting buckle on the same side are connected and fastened by a strap.

[0005] Preferably, extension plates are provided on both sides of the arc-shaped plate.

[0006] Preferably, a first buffer pad is placed between the arc-shaped plate and the oil pillow.

[0007] Preferably, the bottom of the extension plate is provided with a second buffer pad.

[0008] Preferably, a second connecting buckle is provided on the side of the clamp via a connecting block.

[0009] Preferably, a third buffer pad is provided on the inner side of the clamp.

[0010] Preferably, the clamp is located at the upper end of the oil pipe and contacts the bottom of the oil conservator.

[0011] Preferably, the upper end of the clamp is provided with a horizontally folded platform, and a fourth buffer pad that fits against the surface of the oil pillow is provided on the platform.

[0012] The method of using the safety belt hanging pole fixing device for the maintenance of large transformer oil tank includes the following steps: Step 1: After cleaning the surface of the oil conservator of the large transformer to be overhauled, place the arc-shaped plate so that the arc-shaped plate fits against the arc surface of the oil conservator, and the safety belt hanging rod in the middle of the arc-shaped plate is kept vertically upward, and the axis of the safety belt hanging rod is aligned with the axis of the oil pipe connecting the bottom of the oil conservator and the transformer box. Step 2: Install a clamp at the upper end of the oil pipe, so that the upper end face of the clamp contacts the bottom of the oil conservator. At the same time, adjust the angle of the clamp to ensure that the first connecting buckles at both ends of the arc plate correspond one-to-one with the second connecting buckles on both sides of the clamp through the connecting blocks and are on the same side. Step 3: Use straps to connect the first connecting buckle and the second connecting buckle on the same side one by one. Tighten the straps to make the arc-shaped plate fit tightly against the surface of the oil tank and the clamp tightly clamped to the outer wall of the oil pipe, thus completing the fixation of the arc-shaped plate and the seat belt hook.

[0013] Preferably, before performing step 1, a pretreatment step is also included: laying a first buffer pad on the surface of the oil conservator so that the first buffer pad completely covers the area where the arc-shaped plate is to be placed, and the length of the first buffer pad is not less than the length of the arc-shaped plate, so as to avoid the arc-shaped plate directly contacting the surface of the oil conservator and causing wear.

[0014] Preferably, the arc-shaped plate in step 1 is an arc-shaped plate with extension plates on both sides. When placing the arc-shaped plate, the second buffer pad provided at the bottom of the extension plate is made to completely fit with the surface of the oil pillow to limit the tendency of the arc-shaped plate to tilt in the left and right directions.

[0015] Preferably, when installing the clamp in step 2, the third buffer pad provided on the inner side of the clamp is made to fit tightly against the outer wall of the oil pipe to avoid rigid contact between the clamp and the oil pipe, which could cause damage to the surface of the oil pipe.

[0016] Preferably, the clamp in step 2 is a clamp with a horizontally folded platform at the top. When installing the clamp, the angle of the platform is adjusted so that the fourth buffer pad on the platform fits tightly against the bottom surface of the oil tank, so as to disperse the force of the clamp on the bottom of the oil tank when the strap is tightened.

[0017] This invention provides a safety belt hanging rod fixing device and its usage method for the maintenance of large transformer oil conservator. It enables the installation of safety belt hanging rods during the maintenance of large transformer oil conservatores, solving the problem of "high hanging, low use" in existing technologies and ensuring the safety of maintenance personnel. The device combines flexible and rigid connections, using oil pipes as fixing points to secure the safety belt hanging rods. It can effectively fix safety belt hanging rods on oil conservatores with diameters of one or even two meters, solving the problem of not being able to use clamps due to the large diameter of the oil conservator. Furthermore, this device is applicable to various shapes and locations of circular oil conservatores, making it widely applicable. Attached Figure Description

Detailed Implementation

[0019] like Figure 2-3 As shown, a safety belt hanging rod fixing device for maintenance of a large transformer oil conservator includes an oil conservator 1 and an oil pipe 2 connecting the oil conservator 1 and the transformer housing. The oil pipe 2 is vertically connected to the bottom of the oil conservator 1 and includes an arc plate 3 for fitting against the arc surface of the oil conservator 1. A vertically upward safety belt hanging rod 4 is provided in the middle of the arc plate 3. A hanging ring 5 is provided at the upper end of the safety belt hanging rod 4. First connecting buckles 5 are provided at both ends of the arc plate 3. A clamp 6 is provided on the oil pipe 2, and a second connecting buckle 7 is provided on both sides of the clamp 6. The first connecting buckle 5 and the second connecting buckle 7 are set on the same side, and the first connecting buckle 5 and the second connecting buckle 7 on the same side are connected and fastened by a strap 8.

[0020] Preferred, such as Figure 4 As shown, extension plates 9 are also provided on both sides of the arc-shaped plate 3.

[0021] The straps secure the curved plate in the front-to-back direction, while the extension plate 9 prevents the curved plate from tipping over in the left-to-right direction, thus keeping the seat belt hook vertical.

[0022] Preferably, a first buffer pad 10 is also placed between the arc-shaped plate 3 and the oil pillow 1.

[0023] Preferably, the bottom of the extension plate 9 is provided with a second buffer pad 11. The buffer pads are all made of rubber, which serves to isolate, buffer, and prevent slippage.

[0024] Preferred, such as Figure 5 As shown, the side of the clamp 6 is provided with a second connecting buckle 7 via a connecting block 12.

[0025] Preferably, a third buffer pad 13 is provided on the inner side of the clamp 6.

[0026] Preferably, the clamp 6 is located at the upper end of the oil pipe 2 and contacts the bottom of the oil reservoir 1.

[0027] Preferably, the upper end of the clamp 6 is provided with a horizontally folded platform 14, and a fourth buffer pad 15 is provided on the platform 14 to fit against the surface of the oil reservoir 1. When the strap 8 is tightened, the clamp 6 will exert a force on the oil reservoir 1, and the fourth buffer pad increases the contact area and reduces the force.

[0028] The method of using the safety belt hanging pole fixing device for the maintenance of large transformer oil tank includes the following steps: Step 1: After cleaning the surface of the oil conservator 1 of the large transformer to be overhauled, place the arc plate 3 so that the arc plate 3 fits against the arc surface of the oil conservator 1, and the safety belt hanging rod 4 provided in the middle of the arc plate 3 is kept vertically upward, and the axis of the safety belt hanging rod 4 is aligned with the axis of the oil pipe 2 connecting the bottom of the oil conservator 1 and the transformer box. Step 2: Install clamp 6 at the upper end of the oil pipe 2, so that the upper end face of clamp 6 contacts the bottom of oil conservator 1. At the same time, adjust the angle of clamp 6 to ensure that the first connecting buckle 5 at both ends of the arc plate 3 corresponds one-to-one with the second connecting buckle 7 set on both sides of clamp 6 through connecting block 12 and is on the same side. Step 3: Use straps 8 to connect the first connecting buckle 5 and the second connecting buckle 7 on the same side one by one. Tighten the straps 8 to make the arc plate 3 fit tightly against the surface of the oil pillow 1 and the clamp 6 tightly clamped to the outer wall of the oil pipe 2, thus completing the fixation of the arc plate 3 and the safety belt hanging rod 4.

[0029] Preferably, before performing step 1, a pretreatment step is also included: laying a first buffer pad 10 on the surface of the oil conservator 1, so that the first buffer pad 10 completely covers the area where the arc plate 3 is to be placed, and the length of the first buffer pad 10 is not less than the length of the arc plate 3, so as to avoid the arc plate 3 directly contacting the surface of the oil conservator 1 and causing wear.

[0030] Preferably, the arc-shaped plate 3 in step 1 is an arc-shaped plate 3 with extension plates 9 on both sides. When placing the arc-shaped plate 3, the second buffer pad 11 provided at the bottom of the extension plate 9 is made to completely fit with the surface of the oil pillow 1 to limit the tendency of the arc-shaped plate 3 to tilt in the left and right directions.

[0031] Preferably, when installing the clamp 6 in step 2, the third buffer pad 13 provided on the inner side of the clamp 6 is made to fit tightly against the outer wall of the oil pipe 2, so as to avoid rigid contact between the clamp 6 and the oil pipe 2, which would cause damage to the surface of the oil pipe 2.

[0032] Preferably, the clamp 6 in step 2 is a clamp 6 with a horizontally folded platform 14 at the upper end. When installing the clamp 6, the angle of the platform 14 is adjusted so that the fourth buffer pad 15 on the platform 14 fits tightly with the bottom surface of the oil pillow 1, so as to disperse the force of the clamp 6 on the bottom of the oil pillow 1 when the strap 8 is tightened.

[0033] This invention patent addresses the challenges of "high-hanging, low-use" operation during high-altitude maintenance of large transformer oil conservators and the difficulty in securing safety belt hanging poles due to the large diameter of the oil conservator. It innovatively designs a fixing device consisting of an arc-shaped plate conforming to the curved surface of the oil conservator, clamps on the oil pipes, and straps. The arc-shaped plate has a vertically upward-pointing safety belt hanging pole in the middle with first connecting buckles at both ends. The clamps have second connecting buckles on both sides. The straps connect the first and second connecting buckles on the same side, achieving a combination of rigid and flexible fixing. Simultaneously, first, second, third, and fourth buffer pads are provided to protect the contact points between the oil conservator and the arc-shaped plate, the extension plate and the oil conservator, the clamps and the oil pipes, and the bottom of the oil conservator, respectively. The extension plates on both sides of the arc-shaped plate prevent it from tipping over. This device and its corresponding usage method are adaptable to various forms and positions of circular oil conservators, are easy to install, and effectively fill the gap in "high-hanging, low-use" protection for high-altitude maintenance of large transformer oil conservators, ensuring the safety of maintenance personnel.

The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
