On contact bow mounting bracket 2, it is that buffer unit 3 and two is slow that the left and right sides of contact bow mounting bracket 2, which is respectively symmetrically provided with one,
Flushing device 4, as shown in figure 3, described one be buffer unit 3 be compression spring buffer, including bearing pin 7, split pin 8 and compression
Spring 9, the top of the bearing pin 7 is fixedly connected with contacting bow mounting bracket 2, and the bottom of bearing pin 7 is arranged in split pin 8, compression
Spring 9 is set on the bearing pin 7 inside split pin 8, and the upper end of compression spring 9 is fixedly connected with bearing pin 7, under compression spring 9
End is fixedly connected with split pin 8；Described two be that buffer unit 4 includes four-bar linkage structure 10 and extension spring buffer 11, described
Extension spring buffer 11 is horizontally set on the diagonal position of four-bar linkage structure 10, and the top of four-bar linkage structure 10 passes through bolt
It is that the split pin 8 of buffer unit 3 is connected with one, the bottom of four-bar linkage structure 10 is connected by bolt with porcelain insulator 5, insulation porcelain
Bottle 5 is connected by bolt with lowering or hoisting gear 6.
As shown in figure 4, of the present utility model two be that the articulated structure up and down of the four-bar linkage structure of buffer unit is designed as class
Gear engagement structure, the structure can be moved forward and backward to pantograph and upper and lower displacement is while play position-limiting action, pantograph
Displacement is limited within the limits prescribed, can effectively prevent the excess of pantograph from bowing and swinging back, and is buffering by this two
Device and one is that this flexibility of buffer unit+stiff assembly structure ensure that pantograph is contacted with the benign of contact net, prevent by
Pantograph causes to damage in the process of running to bow net, it is ensured that its safety and reliability.
Buffer unit main function is to prevent frizing bow from being impacted during rising bow to contact net, simultaneously because contact
Net has certain altitude changing value in vertical direction, and the device can play certain cushioning effect, its pre-pressing force to contact net
It can ensure that frizing bow is in flexible contact all the time with contact net during work is advanced, it is to avoid rigid contact occur, touch firmly
The situation of serious infringement contact net such as hit.
The lowering or hoisting gear 6 is controlled using jacking system, as shown in figure 5, the jacking system includes blast main 12, cock
13rd, pressure-reducing valve 14, safety valve 15, solenoid directional control valve 16, one-way throttle valve 17 and frizing bow reservoir 18, blast main 12 and pressure-reducing valve
