Abstract
A novel insulating pull rod adopts the structure that an insulating rod and an insertion rod are X-shaped after being connected through a first rotating shaft, and an acute angle Alpha between the insulating rod and the insertion rod is larger than or equal to 10 degrees and less than or equal to 75 degrees; a slide block is connected with one end of a spring; an extension rod is connected with the insulating rod through a second rotating shaft and can rotate around the second rotating shaft; a stop block is connected with the insulating rod; the other end of the spring is fixedly connected with the insertion rod; the spring and the extension rod are fixedly connected; and the stop block can slide in the insulating rod up and down. The insulating rod has the benefits of simple structure, convenience in use, high safety factor, and better application prospect.
Description
Technical field
The utility model relates to a kind of power construction instrument, relates in particular to a kind of novel link rod.
Background technology
In operation of power networks maintenance, the process of the test; Suspension single test lead is very frequent action; Particularly the high-voltage terminal end of 500kV lead or primary equipment is high especially; Owing to compare spaciousness around the transmission line, can the single test line that hang up properly be blown away frequently after the height of position, bring serious potential safety hazard so just for safe operation of electric network and maintenance process.
Summary of the invention
In order to solve the not tight problem of insulating bar suspension single test line in the prior art; The utility model provides a kind of novel link rod; It is characterized in that, comprise sliding shoe, spring, insulating bar, first rotation axis, second rotation axis, inserted link, block, extension bar; Insulating bar is connected with inserted link through first rotation axis, insulating bar with present the X shape after inserted link is connected, and acute angle angle, 10
0≤α≤75
0, sliding shoe is connected with spring one end, and extension bar is connected with insulating bar through second rotation axis; And can be around the rotation of second rotation axis, block is connected with insulating bar, and the spring other end is fixedly connected with inserted link; Spring is fixedly connected with extension bar, and block can slide up and down in insulating bar.
When the utility model was in maximum angle when the acute angle angle of insulating bar and inserted link, the position of block was greater than the position of inserted link at the insulating bar direction projection.
The beneficial effect of the utility model is that simple in structure, easy to use, coefficient of safety is high, has application promise in clinical practice.
Description of drawings
Fig. 1 is a kind of novel link rod structural representation of the utility model.
Fig. 2 is a kind of novel link rod schematic diagram of the utility model.
Embodiment
Specify a kind of novel link rod of the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of novel link rod, the utility model comprise sliding shoe 1, spring 2, insulating bar 3, first rotation axis 4, second rotation axis 7, inserted link 5, block 6, extension bar 8; Insulating bar 3 is connected with inserted link 5 through first rotation axis 4, insulating bar 3 with present the X shape after inserted link 5 is connected, and acute angle angle, 10
0≤α≤75
0 Sliding shoe 1 is connected with spring 2 one ends, and extension bar 8 is connected with insulating bar 3 through second rotation axis 7, and can be around 7 rotations of second rotation axis; Block 6 is connected with insulating bar 3; Spring 2 other ends are fixedly connected with inserted link 5, and spring 2 is fixedly connected with extension bar 8, and block 6 can slide up and down in insulating bar 3.
When the utility model was in maximum angle when the acute angle angle of insulating bar 3 and inserted link 5, the position of block 6 was greater than the position of inserted link at insulating bar 3 direction projections.
When the suspension link rod, sliding shoe 1 is positioned at the top of extension bar 8, and spring 2 is in extended state, and this moment, the acute angle angle of insulating bar 3 and inserted link 5 was a maximum angle, and block 6 also is in the highest point of movement position.When taking off link rod after the off-test, promote block 6 and move downward, rotate around insulating bar 3 with inserted link 5 thereby drive extension bar 8, spring 2 shortens, and then quits work, and the acute angle angle of insulating bar 3 and inserted link 5 constantly diminishes, and finally takes off insulating bar.
As shown in Figure 2, the acute angle angle of insulating bar 3 and inserted link 5 is ∠ BAC, and inserted link 5 is the C point in the position of insulating bar 3 direction projections; Block 6 positions are the D point; The position of block 6 should be greater than the position of inserted link 5 at insulating bar 3 direction projections, i.e. AD＞AC, thereby when guaranteeing the suspension link rod; Behind the B point, the angle position of taking advantage of a situation and just getting into link rod; When taking off link rod, promote block 6 and move down, thereby extension bar 8 rotation axiss that sliding shoe 1 is connected turn clockwise, spring 2 is lax, moves down at block 6 that ∠ BAC constantly diminishes in the process, when AD >=AB, can link rod be taken off.
Claims (2)
