Description

A transformer bushing hoisting tool

technical field

The utility model relates to a hoisting tool, in particular to a transformer bushing hoisting tool, which belongs to the technical field of hoisting tool design and manufacture.

Background technique

The 500kV main transformer bushing is a slender porcelain piece, which is usually installed vertically on the transformer. Since there is no special spreader in the hoisting operation of the 500kV bushing, there are two main problems in the hoisting process of the bushing: first, the bushing needs to be changed from a horizontal state to a vertical state when installing the bushing, so that the The installation of the casing is successfully completed, so the casing needs to be fixed with a waist hoop rope to prevent the slender casing from toppling over. The quality of the waist hoop rope is directly related to the safety of the casing hoisting and the smooth installation, otherwise it will be repeated many times, but only a few professionals can skillfully fasten the waist hoop rope in actual work; When the waist hoop rope is changed from a horizontal state to a vertical state, because the casing oil pillow is larger than the part where the waist hoop rope is tied, the main hanging rope is blocked by the oil pillow, causing a certain inclination of the casing and cannot be directly installed in place. A second adjustment is required. The above problems will affect work efficiency and progress, and cause safety risks in expensive bushings, resulting in delays in work cycles, delays in main transformer power transmission, and reduced reliability of equipment power supply and safe and stable operation of the power grid. Therefore it is necessary to improve the prior art.

Contents of the invention

In order to solve the problem that the existing transformer bushing has no special tools for hoisting and can only be hoisted with cables, which is very easy to cause damage to the bushing during the hoisting process, thus affecting the safe operation of the power grid, the utility model provides a transformer bushing Lifting tools.

The utility model is completed through the following technical solutions: a transformer bushing hoisting tool, which is characterized in that it includes a convex-shaped suspension rod and a suspension rope, the upper part of the convex-shaped suspension rod is provided with a suspension ring, and the two sides of the lower part are respectively provided with fixed through-holes. The slings include two parallel longitudinal slings and a horizontal fixed rope arranged between the longitudinal slings. The upper ends of the two longitudinal slings pass through shackles and fixed passages on both sides of the lower part of the protruding boom respectively. The lower end is connected to the bottom end of the casing, so as to be hung on the main hook through the lifting ring, and then the shackles at the upper ends of the two longitudinal lifting ropes are respectively buckled in the fixed through holes at different positions, and at the same time, the shackles at the upper ends of the two longitudinal lifting ropes The horizontal fixed rope is connected to the upper part of the casing, and the lower ends of the two longitudinal lifting ropes are respectively connected to the flanges of the lower part of the casing, so that the horizontal lifting of the casing can be completed with the cooperation of the auxiliary hook, and the horizontal position can be transformed into Vertical variable hoisting, and the vertical casing and oil conservator are placed between two longitudinal lifting ropes without inclination, and the casing hoisting can be completed at one time without adjustment, which effectively improves the lifting speed.

The fixed through-holes on both sides of the lower part of the convex-shaped suspender are arranged at intervals and symmetrically, so as to adapt to lifting casings of different sizes, and the symmetrical arrangement can ensure the balance during hoisting.

Six fixed through-holes on both sides of the lower part of the protruding suspender are arranged at intervals and symmetrically, so as to adapt to lifting casings of different sizes, and the symmetrical setting can ensure the balance during hoisting.

The slings are arranged in multiples with different lengths, so as to adapt to lifting casings of different sizes.

The utility model has the following advantages and effects: by adopting the above scheme, the problems of easy damage and low work efficiency of the 500kV bushing during hoisting are solved. And in the process of hoisting the casing, according to the size of the casing, buckle the shackle in the fixed through holes on both sides of the lower part of the corresponding convex boom, and choose the appropriate length of the lifting rope at the same time, then the main hook and the auxiliary hook can be matched. Next, complete the horizontal lifting of the casing, the variable lifting from the horizontal position to the vertical position, and place the vertical casing and oil conservator between the two longitudinal lifting ropes without tilting, and the casing can be completed at one time The hoisting without adjustment can effectively improve the hoisting speed. It not only avoids unnecessary damage to the bushing, but also has high hoisting efficiency, which ensures the safe operation of the power grid. It is actually an ideal spreader.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

The transformer bushing hoisting tool provided by the utility model includes a convex-shaped suspender 4 and a suspension rope 2. The upper part of the convex-shaped suspender 4 is provided with a suspension ring 7, and the suspension ring 7 is matched with the main suspension hook. Fix the through hole 3, and the sling 2 includes two parallel longitudinal slings, and a horizontal fixed rope 5 arranged between the two longitudinal slings 2, and the upper ends of the two longitudinal slings 2 are fixed to the suspender 4 through a shackle The through holes 3 are connected, and the lower end is connected with the flange plate 6 at the bottom end of the casing 1. The fixed through holes 3 on both sides of the lower part of the protruding suspender 4 are spaced and arranged six symmetrically. It is suitable for lifting casings of different sizes.

During work, the suspension ring 7 is hung on the main suspension hook 9, and then the two shackles on the upper end of the suspension rope 2 are respectively buckled in the fixed through holes 3 at different positions, and the horizontal fixed rope 5 between the suspension ropes 2 is connected. On the upper part of the casing 1, the lower end of the sling 2 is buckled on the flange 6 of the casing 1 through two shackles respectively, so that the casing 1 can be hoisted horizontally and shifted from the horizontal position with the cooperation of the auxiliary hook 8 It is a variable hoisting in the vertical position, and the casing 1 and the oil conservator in the vertical position are placed between the two longitudinal suspension ropes 2 without inclination, and the hoisting of the casing is completed at one time without adjustment, which effectively improves the hoisting speed.
