Abstract
The utility model provides a locking device that moves of bolt type damper, it includes check washer and a plurality of heliciform preformed armor rods, the upper portion of check washer is the crotch form, and the top of crotch sets up two preformed armor rods installation locator protrusionss, and the substructure of check washer has the slot, and kong kuanyu bolt type damper fastening bolt's hexagon nut width suits, during the use, directly reinforces on operating bolt type damper, and is easy and simple to handle, and non -maintaining, can greatly reduce transmission line's operation maintenance cost, and economic benefits and social are showing. The preformed armor rods mounted position has not only been made clear to two preformed armor rods installation locator protrusionss that its check washer upper portion crotch top set up, still can prevent preformed armor rods landing from the check washer, and it is with the fixed check washer of preformed armor rods, not only can avoid the gold utensil to lead, the ground wire produces the stress concentration point, but also can realize maximum protection to the winding wire of preformed armor rods.
Description
Technical field
The utility model relates to a kind of antihunting device annex, on the screw bolt-type stockbridge damper that particularly a kind of direct reinforcing is in operation, prevents the device of screw bolt-type stockbridge damper bolt looseness, stockbridge damper slippage.
Background technology
Often there is aeolian vibration phenomenon in transmission line, the reason of transmission line aeolian vibration is caused to be when stable breeze winnowing overhead wire, one is formed by certain frequency change and air-flow vortex alternatively up and down at overhead wire lee face, this air-flow vortex makes overhead wire be subject to the impulsive force of the upper and lower alternation of same frequency, when the frequency of this impulsive force is equal with the natural frequency of overhead wire, overhead wire will be made in vertical plane to produce resonance, i.e. aeolian vibration.Aeolian vibration is a kind of high-frequency, guidewire movement by a small margin, and aeolian vibration ripple is smooth sea, and namely node is motionless, and antinode changes alternatively up and down, and it may cause the consequences such as wire strand breakage, gold utensil and shaft tower component damage, even causes disconnected stock to develop into line-outage contingency.
Screw bolt-type stockbridge damper is the vibration-proof equipment generally adopted in overhead transmission line, after its Long-Time Service, easily occurs bolt looseness, cause stockbridge damper slippage, not only do not have the effect of weakening, can wear and tear wire on the contrary, brings potential safety hazard to the safe operation of transmission line.Therefore, on the screw bolt-type stockbridge damper that technically urgently a kind of direct reinforcing is in operation, the device of screw bolt-type stockbridge damper bolt looseness, stockbridge damper slippage is prevented, i.e. a kind of screw bolt-type stockbridge damper loosing-proof device.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency overcoming above-mentioned screw bolt-type stockbridge damper, and on the screw bolt-type stockbridge damper providing a kind of direct reinforcing to be in operation, prevent the device of screw bolt-type stockbridge damper bolt looseness, stockbridge damper slippage, i.e. a kind of screw bolt-type stockbridge damper loosing-proof device.
The technical scheme in the invention for solving the technical problem is: on the screw bolt-type stockbridge damper that this direct reinforcing is in operation, prevent screw bolt-type stockbridge damper bolt looseness, the device of stockbridge damper slippage, i.e. a kind of screw bolt-type stockbridge damper loosing-proof device, it comprises check washer and some helical form preformed armor rodses, the top of described check washer is hook solid, the top of crotch arranges two preformed armor rodses and installs locator protrusions, the substructure of check washer is with slot, the hex nut width of Kong Kuanyu screw bolt-type stockbridge damper fastening bolt adapts, during use, by top crotch being hung on the wire clamp of screw bolt-type stockbridge damper, and make check washer substructure entangle the hex nut of screw bolt-type stockbridge damper fastening bolt with slot, then by by be placed in the middle part of preformed armor rods crotch top arrange two projections between, the cable of two ends respectively to crotch both sides is wound around, to end, check washer is reinforced on the wire clamp of screw bolt-type stockbridge damper.
This screw bolt-type stockbridge damper loosing-proof device provided by the utility model, during use, directly reinforces on the screw bolt-type stockbridge damper be in operation, easy and simple to handle, and non-maintaining, greatly can reduce the operating maintenance cost of transmission line, economic benefit and social benefit remarkable.Two preformed armor rodses that its crotch top, check washer top is arranged install locator protrusions, not only specify that preformed armor rods installation site, preformed armor rods also can be prevented from landing check washer; And it fixes check washer with preformed armor rods, gold utensil not only can be avoided leading, ground wire produces stress concentration point, but also the wire that can be wound around preformed armor rods realizes farthest protection.

The schematic diagram that the check washer of the screw bolt-type stockbridge damper loosing-proof device that Fig. 3 provides for the utility model embodiment is combined with screw bolt-type shockproof hammer thread clip;
Mark in figure: 1, preformed armor rods installs locator protrusions, 2, check washer, 3, slot, 4, the hex nut of fastening bolt.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail, but do not limit protection range of the present utility model.
With reference to accompanying drawing, on the screw bolt-type stockbridge damper that the utility model embodiment provides a kind of direct reinforcing to be in operation, prevent the device of screw bolt-type stockbridge damper bolt looseness, stockbridge damper slippage, i.e. a kind of screw bolt-type stockbridge damper loosing-proof device, it comprises check washer 2 and some helical form preformed armor rodses, the top of described check washer 2 is hook solid, the top of crotch arranges two preformed armor rodses and installs locator protrusions 1, the substructure of check washer 2 adapts with hex nut 4 width of slot 3, Kong Kuanyu screw bolt-type stockbridge damper fastening bolt.
During use, by top crotch being hung on the wire clamp of screw bolt-type stockbridge damper, and make check washer 2 substructure entangle the hex nut 4 of screw bolt-type stockbridge damper fastening bolt with slot 3, then by by be placed in the middle part of preformed armor rods crotch top arrange two projections between, the cable of two ends respectively to crotch both sides is wound around, to end, check washer 2 is reinforced on the wire clamp of screw bolt-type stockbridge damper.
