Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, an embodiment of the present invention is provided.
The embodiment of the invention relates to an arrester mounting bracket, which comprises a bracket 1 and an arrester 3 inserted with the bracket 1, wherein the top center of the bracket 1 is provided with a mounting groove 2, the arrester 3 is inserted into the mounting groove 2, the brackets 1 on the left and right sides of the arrester 3 are provided with screw rods 8, the bottom of each screw rod 8 is fixedly connected with a helical gear 9, the inner cavities of the brackets 1 on the left and right sides of the mounting groove 2 are respectively provided with a guide groove 4, the inner cavity of each guide groove 4 is slidably connected with a guide rod 5, the top of each guide rod 5 is provided with a fixing groove 6, the inner cavity of each fixing groove 6 is provided with a toothed chain 7 meshed and connected with the helical gear 9, one end of the arrester 3 extending into the mounting groove 2 is provided with a limiting groove 10 along the width direction thereof, the left and right sides of the limiting groove 10 are respectively communicated with the guide grooves 4, the inner cavity of each limiting groove 10 is slidably connected with a limiting rod 11, and a telescopic spring 16 is fixedly connected between the two limiting rods 11, the lightning arrester 3 of the left and right sides of the top of the limiting groove 10 is provided with a sliding groove 12, the inner cavity of the sliding groove 12 is fixedly connected with a sliding rod 13, the sliding rod 13 is slidably connected with a sliding block 14, the sliding block 14 is fixedly connected with the limiting rod 11, and the sliding rod 13 on one side, far away from the two sliding blocks 14, is sleeved with a compression spring 15.
The horizontal interval of screw rod 8 and the opening part of guide way 4 in this embodiment is the same with the length of toothed chain 7, can just extrude guide way 4 with gag lever post 11 like this, and guide bar 5 can not get into spacing groove 10 to the doing of installation or dismantlement to arrester 3 has been reduced.
In this embodiment, the sum of the lengths of the two limiting rods 11 is smaller than the length of the limiting groove 10, so that the two limiting rods 11 can be conveniently collected in the limiting groove 10, and the lightning arrester 3 can be conveniently mounted and dismounted.
The working principle is as follows: the installation device, insert the locating column 17 on the arrester 3 aiming at the locating slot 18 on the support 1, make the arrester 3 install in the mounting groove 2, after inserting, because two gag lever posts 11 move along the spacing groove 10 in opposite directions when the reaction force that the elastic deformation of the expanding spring 16 produces, the compression spring 15 pulls the slide block 14 to keep away from each other along the slide bar 13 at the same time, the acting force that the expanding spring 16 produces with the compression spring 15 superposes each other, thus make the gag lever post 11 slide to the guide way 4 along the spacing groove 10, thus realize the locking between arrester 3 and support 1, the slide block 14 cooperates with slide bar 13 and can already play the role of guiding, can also play the spacing to the gag lever post 11 at the same time, when needing to dismantle and maintain, rotate the threaded spindle 8, under the drive of the threaded spindle 8, the helical gear 9 drives the movement of the toothed chain 7, because the toothed chain 7 is connected with the guide spindle 5, therefore the guide spindle 5 is the same with the movement trend of the toothed chain 7, utilize guide bar 5 with the ejecting guide way 4 of gag lever post 11 to realize the unblock between arrester 3 and the support 1, only need to support 1 fixed mounting on the wire pole or on the electric power tower, when the staff is dismantling the maintenance to arrester 3, just need not dismantle support 1 again, only need to dismantle arrester 3 from support 1 get off can, and when installing arrester 3 on support 1, support 1 is also more convenient operation to the fixed of arrester 3.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
