Abstract
The utility model proposes a wire dropping-proof wing-shaped clamp apparatus for changing tension-resisting single chain insulator, including a front clamp (10) and a rear clamp (8) of the wing-shaped clamp apparatus, two pull-plates (5) located between the front clamp and the rear clamp and in permanent connection between both ends of the front and rear clamps, and a leading screw (4) connected between the pull-plates (5) and the rear clamp (8), which is characterized in that one side of the wing-shaped clamp apparatus is attached with a hydraulic cylinder buffer (3), the front end of the buffer (3) is connected with an insulation insurance rope (6), one end of the insulation insurance rope (6) is connected to the front clamp (10). The wire will not drop off even if clamp apparatus loosening, pull plate fracture, leading screw loosing, operate miss and the like situations take place in the procedure of insulator replacement. The wire dropping-proof wing-shaped clamp apparatus of the utility model has simple structure, low manufacturing cost, easy operation, safety and reliability.
Description
Technical field
The utility model belongs to a kind of instrument that uses in the power construction operation, what be specifically related to is a kind of wing jig that uses when changing strain insulator list insulator string on ultra-high-tension power transmission line, and particularly a kind of have a wing jig that prevents wire dropping and have reserve security insurance function.
Background technology
Since transmission line is carried out the operation of charged for replacement insulator, what use when changing the operation of the above strain insulator list of 110kV insulator string is the wing jig of a kind of special use (as shown in Figure 2) always, this wing jig one end is connected with lead, the other end is fixed on the shaft tower cross-arm, by the supporting leading screw on the rotary fixture, single insulator string is drawn in, so that implement the replacing of insulator.Although this wing jig can be finished the replacing of single insulator string, but because the tension force and the load of lead all born by wing jig in whole replacing process, jig is loosening, arm-tie ruptures, leading screw gets loose, wherein any situation of operate miss if take place, lead all can lose stressed and deviates from moment, the deviating from the impulsive force that is produced suddenly and can cause drainage thread to touch the shaft tower cross-arm to make its torsional deformation of lead, may cause the operating personnel to get an electric shock, fall in the high-altitude, object hits, even accidents such as rod disconnection can take place down.
The utility model content
The purpose of this utility model is to propose a kind of wing jig with reserve security insurance function, to ensure the accident that wire dropping can not take place in changing strain insulator list insulator string operation process.
The technical scheme that realizes above-mentioned purpose is: a kind of replacing strain insulator list insulator string is prevented the wing jig of wire dropping, comprise the preceding card, back card of wing jig, between block card and back described before and be fixedly connected on two arm-ties at front and rear card two ends, and be connected leading screw between arm-tie and the back card, it is characterized in that: set up a hydraulic cylinder type buffer in a side of described wing jig, the front end of described buffer is connected with one and thoroughly does away with the edge safety rope, an end of described safety rope and described preceding card connection.
During use, be connected on the shaft tower cross-arm fastening behind the wing jig earlier, preceding card firmly is connected with lead, then the rear end of hydraulic cylinder type buffer is fixed on by connector on the shaft tower cross-arm of wing jig one side to get final product.Jig is loosening, arm-tie ruptures, situations such as leading screw gets loose, operate miss even take place in the work progress, make lead lose the pulling force of wing jig and produce very big instant impact, but, safety rope is connected on the preceding card because being cover, so this moment, the pulling force of lead was just transferred on the safety rope fully, safety rope is delivered to the impulsive force of lead on the hydraulic cylinder type buffer, the moment momentum of the damping slowly-releasing lead by hydraulic cylinder, therefore lead just can not come off, and has just avoided the generation of secondary accident yet.
The anti-wing jig of wire dropping of the utility model only is that the side at original wing jig has installed a hydraulic cylinder type buffer additional, and by a safety rope and preceding card connection, it is simple in structure, and low cost of manufacture is easy to use, and is safe and reliable.
Description of drawings
Fig. 1 is the organigram of the anti-embodiment of the wing jig of wire dropping of the utility model.
Fig. 2 is a user mode schematic diagram embodiment illustrated in fig. 1.
Fig. 3 is a kind of wing jig organigram of the prior art.
Among the figure: 1. shaft tower cross-arm, 2. terminal adapter behind the buffer, 3. hydraulic cylinder type buffer, the 4. supporting leading screw of jig, 5. arm-tie, 6. insulation safety rope 7. has the grooved roller of rope spacing ring, 8. back card, 9. insulator, 10. before card, 11. leads.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
At present the wing jig that uses is by preceding card 10, back card 8 with between front and rear card and be fixedly connected on two arm-ties 5 at front and rear card two ends respectively, and is connected supporting leading screw 4 compositions between arm-tie 5 and the back card, as shown in Figure 3.
The anti-wing jig of wire dropping of the utility model is to have installed a hydraulic cylinder type buffer 3 additional on original wing jig shown in Figure 3, and the front end of buffer 3 is connected with one and thoroughly does away with edge safety rope 6, an end of safety rope 6 and preceding card connection.
During use, back card 8 with wing jig is fixedly connected on the shaft tower cross-arm 1 earlier, before card 10 firmly be connected with lead 11, rear end with hydraulic cylinder type buffer 3 is fixed on the shaft tower cross-arm 1 of wing jig one side by connector then, the another side that the free termination of safety rope 6 is fixed on shaft tower cross-arm 1 that will insulate again gets final product, as shown in Figure 2.
Claims (2)
1. change the anti-wing jig of wire dropping of strain insulator list insulator string for one kind, comprise the preceding card (10), back card (8) of wing jig, between block card and back described before and be fixedly connected on two arm-ties (5) at front and rear card two ends, and be connected leading screw (4) between arm-tie (5) and the back card (8), it is characterized in that: set up a hydraulic cylinder type buffer (3) in a side of described wing jig, the front end of described buffer (3) is connected with one and thoroughly does away with edge safety rope (6), and an end of described safety rope (6) is connected with described preceding card (10).
2. according to the wing jig of the described a kind of anti-wire dropping of claim 1, it is characterized in that: a grooved roller (7) that the rope spacing ring is arranged has respectively been installed in the two ends and the centre position of card (10) before the described wing jig, and the spacing ring that the free end of described safety rope (6) passes on the described grooved roller makes described buffer (3) dynamically be connected with preceding card (10) formation of wing jig.
