Abstract
The present invention relates to a kind of electric power system ± 660kV strain tower and change porcelain insulator suspension bracket.The present invention includes the left side be connected by fixed lever fix snap ring and the right side fix snap ring and fix snap ring respectively with a left side by left socle, right support, coaster ring frame that right fixing snap ring is connected, described coaster ring frame is provided with hanging hole.Adopt the present invention to effectively reduce the activity duration changing strain tower monolithic porcelain insulator, decrease labour intensity, improve the lsafety level of work high above the ground personnel and ground cooperation personnel.
Description
Technical field
The present invention relates to a kind of electric power system ± 660kV strain tower and change porcelain insulator suspension bracket.
Background technology
The all strain towers of ± 660kV eastern circuit of silver all adopt porcelain insulator, must change when damage and null value appear in porcelain insulator, the mode in the past changing strain tower monolithic porcelain insulator is: transmission coaster fixes by work high above the ground personnel on strain insulator porcelain insulator string, ground coordinates personnel monolithic porcelain insulator transmission rope to be passed to edge under porcelain insulator strain insulator-string, operating personnel crouch down on insulator string, are carried above porcelain insulator string by monolithic porcelain insulator with hand.The method wastes time and energy, and easily causes high-altitude article to drop.Form very big potential safety hazard.And because ± 660kV electric pressure all porcelain insulator dishes footpath is comparatively large, monolithic insulator weight is about 30 kilograms, singlely it cannot to be promoted on string at all.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of activity duration effectively reducing replacing strain tower monolithic porcelain insulator, reduce labour intensity, improve work high above the ground personnel and ground coordinate the lsafety level of personnel ± 660kV strain tower changes porcelain insulator suspension bracket.
The present invention adopts following technical scheme:
The present invention includes the left side be connected by fixed lever fix snap ring and the right side fix snap ring and fix snap ring respectively with a left side by left socle, right support, coaster ring frame that right fixing snap ring is connected, described coaster ring frame is provided with hanging hole.
A left side of the present invention is fixed two semicircular ring up and down that snap ring is hinged by one end and is formed, the other end of upper and lower two semicircular ring is provided with left pintle hook lock, the described right side is fixed two semicircular ring up and down that snap ring is hinged by one end and is formed, and the other end of upper and lower two semicircular ring is provided with right pintle hook lock.
Good effect of the present invention is as follows:
Adopt the present invention to effectively reduce the activity duration changing strain tower monolithic porcelain insulator, decrease labour intensity, improve the lsafety level of work high above the ground personnel and ground cooperation personnel.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Accompanying drawing 2 is second annulus opening figure on the left of the present invention.
In the accompanying drawings: 1 fixed lever, 2 left fixing snap rings, 3 right fixing snap ring, 4 left socles, 5 right supports, 6 coaster ring frames, 7 left pintle hook locks, 8 right pintle hook locks, 9 hanging holes.
Embodiment
As shown in Figure 1, the present invention includes the left side be connected by fixed lever 1 fix snap ring 2 and the right side fix snap ring 3 and fix snap ring 2 respectively with a left side by left socle 4, right support 5, coaster ring frame 6 that right fixing snap ring 3 is connected, described coaster ring frame 6 is provided with hanging hole 9.
A left side of the present invention is fixed two semicircular ring up and down that snap ring 2 is hinged by one end and is formed, the other end of upper and lower two semicircular ring is provided with left pintle hook lock 7, the described right side is fixed two semicircular ring up and down that snap ring 3 is hinged by one end and is formed, and the other end of upper and lower two semicircular ring is provided with right pintle hook lock 8.
The structure that the present invention relies on two insulator string arranged in parallel, make full use of equipment inherently condition, utilize insulator near porcelain insulator to be replaced, snap ring 2 is fixed by a left side of the present invention, the present invention is fixed on the steel cap between two insulators by right fixing snap ring 3, as shown in Figure 2, namely left fixing snap ring 2 is first opened, second annulus on right fixing snap ring 3, a left side is fixed snap ring 2, first annulus of right fixing snap ring 3 is stuck in after on steel cap, again left pintle hook lock 7 and right pintle hook lock 8 are screwed, by two steel cap clampings, be fixed on two insulator string by the present invention.When operating personnel carries out the operation of replacing monolithic insulator on the insulator, coaster suspension hook is hung in the hanging hole 9 on coaster ring frame 6, article are passed near work high above the ground person works position by coaster by ground staff, work high above the ground personnel to be taken Work tool and standby redundancy from setting by coaster, lift monolithic insulator.The present invention can effectively reduce work high above the ground personnel labor intensity, improves operating efficiency, as Work tool secondary protector, can decrease the risk of falling object from high altitude again simultaneously, ensure that work high above the ground personnel and ground personal safety.
