Description
Technical field
The present invention relates to the connecting device between a kind of electric express locomotive pantograph collector head and the pantograph link span.
Background technology
Electric locomotive obtains electric energy by the pantograph that is installed in its roof from contact system, is used to drive its operation.Pantograph be subjected to electric slide plate and contact line conducting wire surface with certain pressure direct contact and relative sliding.During the locomotive high-speed cruising, the collision that lead just fluctuates because the vibration of car body and contact system dangle, be between bow, net and impact contact, rock and the concussion state, make the state that connects when breaking in the time of may being between bow, net, so just be unfavorable for that locomotive obtains electric energy swimmingly from contact system, be unfavorable for the safety and steady operation of locomotive.Therefore, in train travelling process, require pantograph when sliding at a high speed, can remain and contact, keep the good stream mode that is subjected to the steady of contact system.
Contact between the bow net, be subjected to factors such as stream mode and pantograph collector head structure, bow net contact pressure and bow supporting (or suspension) mode relevant.The wherein supporting of bow (or hang) device to decay by the concussion that the vibration and the impact of car body and contact system causes, reduce the bow body rock and swing plays an important role.
Prior art generally adopts supporting (or the hang) device of spiral tension spring or laminated spring, promptly adopts spiral tension spring or laminated spring to be connected between bow body and pantograph link span.This connecting device is after locomotive speed surpasses 350 kilometers/hour, because the aerodynamic drag of its suspension gear is bigger, its bow body rocks and fluctuates bigger during high-speed motion, and because the damping that extension spring is hung is little, the damping capacity of bow body concussion is poor during to high-speed cruising, can not effectively weaken the impact between bow net and trembles, so that the bow net off-line often appears, cause spark, be unfavorable for that the stable of locomotive flowed, be unfavorable for the high-speed smooth operation of locomotive.
Summary of the invention
Purpose of the present invention just is to provide a kind of Packing spring box of high speed pantograph bow, can the self adaptation contact system the dangle fluctuation of lead of this device, bow with net between have good followability; The concussion that vibration and the impact by car body and contact system of decaying effectively causes; And its compact conformation, in light weight, the windward side is little, the rocking and swing little of caused bow body.What can guarantee locomotive is subjected to stream good, and safe in operation is steady.
The present invention solves its technical matters, and the technical scheme that is adopted is:
A kind of Packing spring box that is used to connect pantograph collector head and pantograph link span, its composition is:
The bow coupling seat top of spring case links to each other with bow carbon slide plate by bolt, the bottom is hinged by bearing pin and U-shaped hinged-support, U-shaped hinged-support bottom is connected with the piston rod upper end by screw, piston rod places in the piston barrel, piston barrel by screw retention in supporting cylinder, on the cylindrical shell mount pad, the cylindrical shell mount pad is installed on the bow cross bar of pantograph by bolt again by screw retention at the middle part of supporting cylinder, and the last armed lever of bow cross bar and pantograph link span is hinged;
The supporting cylinder lower end connects the cylindrical shell bottom by screw, and the lower position of cylindrical shell bottom is provided with the throttle governing screw, and there is damping hole at throttle governing screw center;
Piston rod is the tubular cavity structure, and it is disconnected that the plunger medium position is provided with tabula, is provided with spring at tabula between the disconnected and cylindrical shell bottom, and piston rod outer wall middle part is provided with position-limited trough longitudinally, and the middle part of supporting cylinder is provided with the locating dowel pin adaptive with position-limited trough.
The principle of work of apparatus of the present invention is:
One, the piston rod with the connection of bow carbon slide plate can slide up and down in piston barrel, because being coil spring, supports piston-rod lower end, upper and lower flexible under the spring force effect with the bow carbon slide plate that piston rod is bound up, the dangle fluctuation of lead of self adaptation contact system has good followability between making bow and netting; Simultaneously, because piston rod, piston barrel, seal ring and cylindrical shell bottom constitute a fully enclosed cavity, when piston rod is subjected to external force to desire to slide up and down, can be subjected to the shock damping action of airtight cavity, can decay pantograph collector head because of vibrating and impact the concussion that causes, bow is reduced to minimum because of vibrating and impact the concussion that causes, locomotive is stablized flowed.
Compared with prior art, the invention has the beneficial effects as follows:
One, because the spring damping structure of apparatus of the present invention, spring installation makes the fluctuation of its lead that can self adaptation contact system dangles, bow with net between have good followability; The existence of the air damping effect in the piston barrel simultaneously, the concussion that vibration and the impact by car body and contact system of can also decaying effectively causes; Bow is reduced to minimum because of vibrating and impact the concussion that causes, locomotive is stablized flowed.
Two, need only change different adjusting impedance screws, change the damping hole size, i.e. the shock damping action power size of scalable closed chamber body is conveniently adjusted different vehicles and road conditions, make applied range of the present invention, implement more convenient.
Three, apparatus of the present invention compact conformation is in light weight, and the windward side is little, the rocking and swing little of caused bow body.Therefore apparatus of the present invention can guarantee well being flowed of bow, guarantee the safety and steady operation of locomotive.
Above-mentioned piston rod upper end is equipped with can be with the dust boot of piston rod telescopic moving.
Dust boot can avoid foreign material to fall into piston barrel, improves the reliability and stability of device.
Above-mentioned piston barrel top is provided with dust-proof seal ring, and piston-rod lower end is provided with seal ring.
Like this, can guarantee the sealing shock damping action of piston barrel, the operation that can make piston rod again more freely, smoothly.
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
