Abstract
The invention discloses a suspension clamp with an automatic limiting mechanism. The suspension clamp comprises a trough-shaped shell, wherein a trough-shaped pinch plate matched with the trough-shaped shell is arranged in the trough-shaped shell; guide ridges are distributed on two outer side surfaces of the trough-shaped pinch plate; guide grooves matched with the guide ridges are distributed in the inner side surface, matched with the guide ridges, of the trough-shaped shell; fixed lugs are arranged at two ends of the trough-shaped shell respectively; a pressing plate is hinged with each fixed lug; an eccentric wheel is rotationally arranged at the bottom end part of each pressing plate; the longest wheel edge of each eccentric wheel is attached to the upper end of the trough-shaped pinch plate; two pressing plates are linked through a connection plate; the middle part of the connection plate is hinged with the trough-shaped shell through a reinforcing plate; the upper end parts of the front end surfaces of the two pressing plates are hinged with two pull rods; and a chuck is arranged at the end part of one pull rod and the other pull rod is connected with a rotating shaft of the corresponding eccentric wheel. The suspension clamp can be automatically adjusted to move a certain amount of displacement, thereby distributing loads on a power transmission line, the condition that the power transmission line is pulled off due to the fact that adjustment and self-locking cannot be carried out is avoided and the loss is reduced.
Description
Technical field：
The present invention relates to cable gold utensil field, relates generally to a kind of suspension clamp with automatic limiting mechanism.
Background technology：
The equipment that is directly connected to that wire is arranged on steel tower in power delivery circuit mainly adopts suspension clamp and strain clamp, current
Suspension clamp is made up of wire clamp hull, connecting bolt, U-bolt, tension disc, pin etc., and such suspension clamp can only be played and be carried
The effect of wire is taken, the effect of self-locking, such as runs into special circumstances or heavy snow weather, high pressure after not reaching adjustment tension force and adjusting
High-tension electricity transmission tower, so as to increased the load of power transmission line, can be caused by power transmission line due to external force or the gravity of frost on power transmission line
Break, cause huge loss.
The content of the invention：
The object of the invention is exactly for the defect for making up prior art, there is provided a kind of suspension clamp with automatic limiting mechanism, solution
Determined power transmission line load it is big, high-tension electricity transmission tower is broken by power transmission line, and the problem for bringing about great losses.
The present invention is achieved by the following technical solutions：
A kind of suspension clamp with automatic limiting mechanism, is included trough-shaped housing, is provided with and is coordinated with which in the trough-shaped housing
Flute profile buckle, be distributed with two lateral surface of the flute profile buckle and lead rib, on the medial surface that the trough-shaped housing is coordinated with which
The guide groove of rib cooperation is distributed with and leads, and the trough-shaped housing is respectively arranged at two ends with fixed ear, pressure is hinged with the fixed ear
Tight plate, the bottom of the pressure strip are rotatablely equipped with an eccentric, and the most long wheel side of the eccentric is upper with flute profile buckle
Face end fits, and is linked by connecting plate between two pressure strip, and the connection between the connecting plate and pressure strip is hinge
Connect, the middle part of the connecting plate is articulated and connected with trough-shaped housing by reinforcing plate, the upper part of the two pressure strips front end face
Two pull bars are not hinged with, the end of one pull bar is provided with chuck, and another pull bar is connected with the rotating shaft of eccentric, institute
The upper end for stating pressure strip is provided with for installing fixed installing hole.
The section of described trough-shaped housing groove is U-lag, and the section of the flute profile buckle groove is arcuate groove.
Described chuck includes U-shaped clip, and the U-shaped clip includes flexible arc plate, the flexible arc plate
Both sides have been respectively articulated with two fix bars, and it is the circular bar structure of two halves that two fix bar is respectively section, and two halves are circular
Body of rod pairing after rounded structure, its outer surface is distributed with the screw thread of mutual pairing, and is combined with locking nut.
By being provided with the flute profile buckle coordinated with which in trough-shaped housing, clamp wire can be facilitated, by pressure strip
The structure of eccentric, can carry out a certain degree of compression and conveying to flute profile buckle, and the eccentric can be with the stress of pull bar
And rotated, so as to adjust the fastening distance between flute profile buckle and trough-shaped housing, so that wire can be carried out to a certain degree
Regulation, and by when pull bar run to need adjust amount after, the bottom of eccentric is reached when holding out against state again, you can
Voluntarily lock.So as to the effect of self-locking after there is adjustment tension force and adjusting, can be affected by external force according to wire, voluntarily can be adjusted
The certain displacement of section movement, so as to the load distributed on power transmission line, it is to avoid cannot adjust and self-locking, and be pulled off, reduce
Loss.
It is an advantage of the invention that：
The present invention has the effect of self-locking after adjustment tension force and regulation, can be affected by external force according to wire, voluntarily can be adjusted
The certain displacement of movement, so as to the load distributed on power transmission line, it is to avoid cannot adjust and self-locking, and be pulled off, reduce damage
Lose.
