one end of the handle bar 350 is rotatably connected with the base 360, the other end of the handle bar is wrapped with an anti-slip rubber sleeve 370 made of rubber or silica gel, one end of the connecting rod 340 is rotatably connected with the middle position of the pressure lever 330, and the other end of the connecting rod is rotatably connected with the middle position of the handle bar 350;
when the pressing rod 330 drives the pressing block 320 to reach a position where the pressing block and the limiting groove 310 clamp the cable together, two ends of the connecting rod 340 are respectively collinear with three points of a first connecting point 301 and a second connecting point 302 which are rotationally connected with the pressing rod 330 and the handle rod 350, and a third connecting point 303 which is rotationally connected with the handle rod 350 and the base 360, and a straight line formed by two points of the first connecting point 301 and a straight line formed by two points of the fourth connecting point 304 and the first connecting point 301 which are rotationally connected with the base 360 and the connecting rod 340, and the pressing rod 330 are perpendicular to a straight line formed by two points of the first connecting point.
The fixing clamp 300 with the structure does not need to lock the pressing block 320 and the limiting groove 310 through bolts, so that tools such as a spanner and the like are not needed when the pressing block 320 and the limiting groove 310 are adjusted to be opened and closed to clamp or loosen the bypass cable in the limiting groove, the opening and closing can be directly controlled by hands, and the fixing speed of the cable is accelerated. The principle is that when the pressing rod 330 drives the pressing block 320 to reach the position where the pressing block and the limiting groove 310 clamp the bypass cable together, as shown in fig. 3 and 4, three points of the first connection point 301, the second connection point 302 and the third connection point 303 are collinear, a straight line formed by the three points is parallel to the Y-axis direction, and a straight line formed by the first connection point 301 and the fourth connection point 304 is parallel to the X-axis direction.
The force analysis was as follows: when the bypass cable clamped by the pressing block 320 and the limiting groove 310 together shakes, the pressing block 320 tends to be loosened, a force in the positive direction of the Y axis is applied to the pressing rod 330, the pressing rod 330 applies the force in the positive direction of the Y axis to the pressing rod 330 through the first connecting point 301, the connecting rod 340 applies the force in the positive direction of the Y axis to the handle bar 350 through the second connecting point 302, and the base 360 applies the force in the negative direction of the Y axis to the handle bar 350 through the third connecting point 303 to counteract the force in the positive direction of the Y axis applied to the handle bar 350 by the connecting rod 340 through the second connecting point 302; at this time, the positive and negative forces along the Y-axis on the handle lever 350 and the connecting rod 340 keep a balanced state, so as to ensure that the bypass line is stably fixed in the pressing block 320 and the limiting groove 310.
When an operator needs to loosen the bypass cable, the operator holds the anti-slip rubber sleeve 370 of the handle bar 350 by hand to apply a force to the handle bar 350 deviating from the Y-axis direction, so as to break the stress balance of the handle bar 350 and change the state of the handle bar 350, the handle bar 350 applies a force to the connecting rod 340 deviating from the Y-axis direction through the second connecting point 302, so as to break the stress balance on the connecting rod 340 and change the state of the connecting rod 340, and the connecting rod 340 pulls the pressure rod 330 through the first connecting point 301 so as to drive the pressure block 320 to loosen the bypass cable.
Consequently, this fixation clamp 300 structure avoids the bypass cable because rock and causes the pine to take off, can pass through manual quick fixed cable again, has promoted security performance and assembly efficiency.
As shown in fig. 1, in the above embodiment, the surface of the support rod 410 and/or the main body rod 100 is coated with a hydrophobic material. In rainy days, the rainwater may creep between the bypass cable and the phase conductor crossed by the isolation fork 420 along the main body rod 100 and the support rod 410, and the hydrophobic material can effectively prevent the rainwater from attaching to the main body rod 100 and the support rod 410, thereby improving the safety performance.
As shown in fig. 1, in addition to the above embodiment, the number of the hooks 200 is two or more, and two or more hooks 200 are arranged in parallel at the tip of the main body lever 100. In order to increase the stability of the main body pole 100 hanging on the wire, the number of the hooks 200 is two or more, and the sway of the bypass cable is reduced.
The working principle of the temporary fixing bracket for high-voltage cables is illustrated as follows:
when the bypass cable needs to be electrically connected to the upper phase conductor, the bypass cable is fixed in the fixing clip 300, then the hook 200 is hung on the upper phase conductor, the isolation fork 420 is clamped to the middle phase conductor or the lower phase conductor, and then the bypass cable is electrically connected to the upper phase conductor.
When the bypass cable needs to be electrically connected with the middle phase conductor, the bypass cable is fixed in the fixing clip 300, then the hook 200 is hung on the middle phase conductor, the isolation fork 420 is used for forking the lower phase conductor, and then the bypass cable is electrically connected with the middle phase conductor.
When the bypass cable needs to be electrically connected to the lower phase conductor, the bypass cable is fixed in the fixing clip 300, and then the hook 200 is hung on the lower phase conductor, and the isolation fork 420 may be omitted.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
