The invention discloses an adjustable installation support for a drop-out fuse, and solves a problem that the angle of the drop-out fuse is difficult. The lower part of a support (15) shaped like a bowl pipe is a cam-shaped box body (4), and the cam-shaped box body (4) is movably disposed on a bottom plate (2). The top of the support (15) shaped like a bowl pipe is fixedly connected with a connecting plate (16) of a drop-out fuse clamping hoop (17). The bottom plate (2) is fixedly provided with two fixed supports (3), and a connecting hinge pin (6) between the two fixed supports (3) is movably connected to the center of the cam-shaped box body (4) in a passing-through manner. The center of the connecting hinge pin (6) is fixedly provided with a gear (5), and the central part of a lifting lever (7) is hinged to a hinge pin (8). A lifting hook at the top of the lifting lever (7) abuts against teeth of the gear (5). The support is firm in installation, and can achieve the convenient and flexible adjustment of the angle of the drop-out fuse.
Description
Technical field
The present invention relates to disclosure satisfy that in-site installation angle requirement in a kind of newly-built and maintenance of distribution network line at the scene
Flexibly adjustable fuse switch mounting bracket.
Background technology
A kind of short-circuit protection that fuse switch is the most frequently used on 10kv distribution line branch line and distribution transformer is opened
Close, there is after fusing an obvious cut-off point, possess the function of disconnecting switch.Fuse switch can be reliable and effective
Fuse and fall, the protection for equipment and circuit plays a very important role.When fuse switch is installed, should ensure that
Solid and reliable it is impossible to have any rock and rock, fusion tube should have certain downward inclination angle it is ensured that after fuse failure, melting
Pipe can rely on the weight of itself to come off rapidly and disengagement failure.At present, the model of fuse switch and producer are different, voltage
Grade is not high, and mounting process is uneven, and setting angle is also unreasonable, adds running environment also each not phase of erecting bed
With the phenomenon such as aging corrosion of longtime running happens occasionally, and leads to many fuse switches effective after fuse failure
Fall with disengagement failure, cause accident expanded range, the loss causing also increases therewith.Therefore, ensureing fuse switch
On the premise of working properly, scene is badly in need of developing a kind of general mounting bracket, both can guarantee that solid and reliable by drop type
Fuse is fixed on cross-arm, and setting angle is flexibly adjustable simultaneously, meets the convenient purpose adjusting during maintenance.
Content of the invention
The invention provides a kind of adjustable fuse switch mounting bracket, solve fuse switch angle adjustment
Difficult technical problem.
The present invention is to solve above technical problem by the following technical programs:
A kind of adjustable fuse switch mounting bracket, including cross-arm, fuse switch and bowl of a pipe shape support,
Base plate is fixedly installed on cross-arm, the bottom of bowl of a pipe shape support is cam-like box body, and cam-like box body is movably arranged on base plate
On, the top of bowl of a pipe shape support and the connecting plate of fuse switch clip are fixed together, in fuse switch
It is formed with angle α and plumb line between, two fixed supports are fixedly installed on base plate, it is solid that cam-like box body is movably arranged on two
Between fixed rack, the connection bearing pin between two fixed supports is that activity wears the center being connected on cam-like box body, in connecting pin
The center of axle is fixedly installed gear, and the bowl of a pipe shape support above gear is fixedly installed bearing pin, the middle part of driving lever
It is hinged on bearing pin, the hook of dialling on driving lever top is connected together with the tooth top on gear.
Regulation button spindle upper end support ring is respectively arranged with bowl of a pipe shape support and adjusts button spindle lower end support ring,
Regulation button spindle activity is worn and is connected on regulation button spindle upper end support ring and adjusts between the support ring of button spindle lower end, is adjusting button
Stage clip is provided with bar, the regulation button spindle below ring washer on stage clip is provided with ring washer on stage clip, adjust the bottom of button spindle
End is hinged with driving lever tail end by connects hinge.
Gear has 720 teeth, often rotates 0.5 ° of a tooth scalable.
The present invention firmly installs, can in new clothes or maintenance the convenient, flexible angular adjustment realizing fuse switch,
Disclosure satisfy that the job requirement at scene.
Brief description
Fig. 1 is the structural representation of the present invention.
Specific embodiment
The present invention is described in detail below in conjunction with the accompanying drawings:
