Description
Technical field
The present invention relates to a kind of current transformer installation auxiliary devices.
Background technology
The installation site of current transformer is located at the rear lower of switchgear in 35KV switchgears, and current transformer is when mounted
It does not move and support device, typically by being manually carried in switchgear corresponding installation site and being lifted, due to electricity
The dead weight of current transformer is larger, at least needs two people's cooperations that could complete assembly, labor intensity is larger.And due to by installation position
It sets and the limitation in inside switch cabinet space, more increases the difficulty of installment work, make the installation of current transformer extremely not
Just, if in assembling process mismate, installation personnel or current transformer can also be damaged or damaged.
Invention content
The purpose of the present invention is to provide a kind of current transformer installation auxiliary devices, mutual to solve electric current in the prior art
The inconvenient problem of sensor installation.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme that：
A kind of current transformer installation auxiliary device, including lift cart and for frame in switchgear corresponding mounting plate and
Guide rail between lift cart, guide rail are equipped with for rolling cooperation so that current transformer slides into switch with current transformer
Rolling element in cabinet.
Guide rail is hinged with lift cart.
The lift cart is scissors type elevating trolley.
Scissors type elevating trolley includes chassis and the interior scissor arms being hinged and connected on chassis and outer scissor arms, interior,
Outer scissor arms are in " entering " font, and interior scissor arms bottom has slide construction, and outer scissor arms bottom and chassis are hinged, the guide rail with
It is hinged at the top of interior scissor arms.
The rolling element is ball.
One end far from lift cart has the lapping plate for being overlapped on the mounting plate on the guide rail.
The beneficial effects of the present invention are：Installation auxiliary device includes lift cart and accordingly pacifies in switchgear for frame
Guide rail between loading board and lift cart, by the adjusting of lift cart height, make guide rail bracket mounting plate and lift cart it
Between form a suitable installation supporting surface, be no longer needed for manually lifting in this way, reduce labor intensity, and be arranged on guide rail
Have and current transformer is facilitated to slide into the rolling element in switchgear, thus can current transformer be placed on guide rail in advance
On, manually slightly strength can slide into switchgear, facilitate the movement of current transformer, which makes current transformer
Installation become simple and convenient.

Specific implementation mode
The implementation of current transformer installation auxiliary device is for example shown in Fig. 1 ~ Fig. 4, including lift cart, lift cart and opens
Close corresponding mounting plate in cabinet（It is not shown in figure）Between be provided with guide rail 2, lift cart includes chassis 1, and chassis 1 is equipped with and leads
The hinged crane of rail 2, crane include top and the hinged interior scissor arms 4 of guide rail 2 and the outer scissor hinged with interior scissor arms 4
Arm 3, inside and outside scissor arms are in " entering " font, and the bottom of outer scissor arms 3 is hinged with chassis 1, and 4 bottom of interior scissor arms is equipped with lifting and rolls
Wheel 5, chassis 1 are equipped with the guide groove 6 rolled for lifting idler wheel 5, the hydraulic thrust for controlling crane lifting are additionally provided on chassis 1
Bar 7, hydraulic push rod 7 are equipped with handle 8, and the bottom on chassis 1 is equipped with Moving caster 9.Guide rail 2 is by passing through fixing axle 23 fixed two
Block bearing mounting plate 21 forms, and one end of bearing mounting plate 21 and interior scissor arms 4 are hinged, and bearing mounting plate 21 is separate with interior scissor
The hinged other end of arm 4 is extended with one section of lapping plate 24 for being overlapped on the mounting plate, and bearing mounting plate 21 is equipped with
Two row Universal caster bearings 22, Universal caster bearing 22 include ball 221 and are used for and 21 fixed mounting hole of bearing mounting plate
222。
The operation principle of the device is：In use, turning on the switch the back door of cabinet, current transformer is made by Moving caster 9
Installation auxiliary device is moved to the suitable position outside switchgear, and lapping plate 24 is overlapped on current transformer in switch cabinet
On mounting plate, the height that hydraulic push rod 7 adjusts crane is controlled by handle 8, so that guide rail 2 is in suitable heeling condition, so
Current transformer is placed on guide rail 2 afterwards, manually slightly exerting a force makes current transformer slide into switchgear installs accordingly
Position can carry out installation fixation to current transformer at this time.
Current transformer installation auxiliary device includes lift cart, installation can be made auxiliary by the adjusting of lift cart height
Device is helped to be suitable for the switchgear of different model.Guide rail is hinged with lift cart, thus one end of guide rail can be made first to overlap
On a mounting board, so that guide rail is in suitable heeling condition by the adjusting of other end lift cart, current transformer is made more to hold
It easily slides in switchgear, facilitates the adjusting of guide rail and the movement of current transformer, and when without using installation auxiliary device,
Guide rail one end can be positioned on ground, when avoiding guide rail and being fixedly connected with lift cart, guide rail is in overhanging state and deposits
It is being easy to scrape the danger hurted sb.'s feelings.Inside and outside scissor arms are in " entering " font, and guide rail need to only be hinged at the top of interior scissor arms, compare
Traditional crane, outer scissor arms top no longer play a supportive role, also no longer need that slide construction is arranged at the top of interior scissor arms, this
Sample conveniently could make guide rail be adjusted to heeling condition, to facilitate the movement of current transformer, while simplify the knot of crane
Structure makes setting and the operation is more convenient.
In the other embodiment of current transformer installation auxiliary device：Rolling element can also be multiple rollers being mutually parallel
Wheel；Inside and outside scissor arms can also be in " X " type, and guide rail is still hinged at the top of interior scissor arms；Lift cart can not be scissor-type
, the hydraulic cylinder of push rod upward that can be provided on chassis, guide rail and push rod are hinged at this time；Guide rail also may be used with lift cart
To be to be fixedly connected, guide rail is not rotatable.
