Description

A kind of on-load tap changers of transformers boom hoisting
Technical field
This utility model relate to electric power system use small-sized hanging device, a kind of simple to operate, easy to use, The on-load tap changers of transformers hanging apparatus of work safety.
Background technology
Increasing along with indoor substation, the situation that main transformer uses at indoor location increases the most increasingly, transformation Device is most important electrical equipment in whole electric substation, and the load ratio bridging switch of transformator plays regulation transformer output voltage Effect, be whole transformator " heart ".Supply voltage stability and the qualification rate of electric substation are played by load ratio bridging switch Vital effect.It is to use flange to be attached that load ratio bridging switch is typically mounted at the inner barrel of transformator, and Transformer body is the highest, it is therefore desirable to use crane gear that shunting switch just can be made must to winch to ground from cylinder safely.Meanwhile, V type switch weight heavier in load ratio bridging switch has 40KG, lighter M type switch to reach 20KG, use manpower to be lifted by switch Extremely difficult to ground, and switching is precision equipment, lifts during passing if it occur that clashing and breaking are unexpected, all can make to switch performance Becoming the biggest infringement, and above transformator, working space is narrow and small, after transformer oil is unrestrained, transformer top is wet and slippery, is unfavorable for Personnel carry out operation up.Therefore, it is badly in need of a kind of boom hoisting that can the most just install and use at present, solves The problem that indoor transformer cannot use crane gear.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that one is simple to operate, easy to use, work is steady Fixed, the on-load tap changers of transformers boom hoisting of raising maintenance efficiency.
Solution of the present utility model is:
A kind of on-load tap changers of transformers boom hoisting, including base, support bar, arm, electrical hoist and suspension hook, It is characterized in that the lower end of support bar is vertically connected with base, the side of base is provided with major arc type gripper shoe, major arc type gripper shoe The through hole that on the ring flange being provided with and install on-load tap changers of transformers, connecting hole is corresponding, post upper is provided with and can revolve The sleeve turned or the upper end of bearing, sleeve or bearing are provided with horizontal arm, and the upper surface of arm is provided with chute, sets in chute Having the coaster of band pulley, suspension hook is connected with coaster through U-shaped support, and one end of arm is provided with electrical hoist;One end of drag-line Being connected with electrical hoist, the other end is connected with coaster.
Base described in the utility model is provided with arm corresponding to major arc type gripper shoe and is provided with coaster, and base opposite side sets Having pole, the upper end of pole is connected with post upper, and pole and support bar are 20-30 degree angle, to increase support bar Stability so that it is work safety.
Two arms of U-shaped support described in the utility model are respectively provided at outside arm and are connected with the pin of coaster both sides Connecing, suspension hook is connected with U-shaped support through bottle gouard moved by hands, to improve the stability of work.
Coaster described in the utility model is provided with tabular car body, is provided with the cunning matched with chute under car body through support Wheel, is provided with drag-line link before car body, car body is respectively provided on two sides with the pin being hinged mutually with U-shaped support two-arm.
When this utility model uses, first base is fixed by the connection of major arc type gripper shoe with flange, more manually On-load tap changers of transformers is hung out by calabash and suspension hook, then will move through manual rotation by electrical hoist and hang Arm, makes on-load tap changers of transformers be placed on setting position, has simple to operate, easy to use, working stability, work efficiency Advantages of higher.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is a kind of schematic diagram of base in this utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
As it is shown in figure 1, a kind of on-load tap changers of transformers boom hoisting, including base 1, support bar 2, arm 3, electronic Hoist engine 4 and suspension hook 5, the lower end of support bar 2 is vertically connected with base 1, and the side of base 1 is provided with major arc type gripper shoe 6, major arc Type gripper shoe 6 is provided with the through hole corresponding with connecting hole on the ring flange installing on-load tap changers of transformers, the described end Seat 1 is provided with arm corresponding to major arc type gripper shoe and is provided with coaster 8, and base opposite side is provided with pole 10, the upper end of pole 10 with Support bar 2 upper end is connected, and pole 10 and support bar 2 are in 20-30 degree angle, to increase the stability of support bar so that it is work Safety, support bar 2 upper end is provided with rotatable sleeve or bearing 7, and the upper end of sleeve or bearing 7 is provided with horizontal arm 3, arm The upper surface of 3 is provided with chute, is provided with the coaster 8 of band pulley in chute, and suspension hook 5 is connected with coaster 8 through U-shaped support 9, this reality It is respectively provided at outside arm with two arms of novel described U-shaped support 9 and is connected with the pin 11 of coaster both sides, suspension hook 5 Being connected with U-shaped support through bottle gouard moved by hands 12, to improve the stability of work, coaster described in the utility model is provided with tabular Car body, is provided with the pulley matched with chute through support under car body, be provided with drag-line link before car body, car body be respectively provided on two sides with The pin 11 that U-shaped support two-arm is hinged mutually, one end of arm 3 is provided with electrical hoist 4;One end of drag-line and electrical hoist 4 Being connected, the other end is connected with sliding 8 cars.When this utility model uses, first by base by major arc type gripper shoe and flange Connect fixing, more manually on-load tap changers of transformers is hung out by calabash and suspension hook, then will be moved by electrical hoist Dynamic and manually rotary suspension arm, makes on-load tap changers of transformers be placed on setting position, has simple to operate, user Just, working stability, work efficiency advantages of higher.
