Description

The contact system multifunctional localizer

Technical field

The utility model relates to the registration device on the electrification railway contact net, particularly relates to a kind of contact system multifunctional localizer.

Background technology

Steady arm is the registration device that is used for fixing the contact wire position on the electrification railway contact net, and the quality of steady arm directly influences normally getting of locomotive and flows and operation.The patent No. is that 00261391.3 utility model patent specification sheets discloses a kind of contact system steady arm, it comprises clevis bolt, locating rack, bogie truck, swing pipe and wire clamp, locating rack wherein is hinged by vertical shaft and bogie truck, swing pipe is connected on the bogie truck by pin, also is provided with leaf spring and installs by way of compensation.This locator structure complexity, volume are big, can not satisfy at present fast, the high-speed electric railway contact system is to the requirement of steady arm.In addition, existing steady arm base is to adopt steel casting, registration arm is many to be made by aluminum alloy materials or common A3 steel pipe, adopt riveted joint or hexagonal compacting welding manner between registration arm and two attaching parts, the steady arm of this material is corroded easily, oxidation and cause the mechanicalness obstacle, and riveted joint or hexagonal compacting welding connecting mode easily at the riveted joint position of aluminum alloy or the weld of steel pipe produce the metal fatigue fracture or snap, steel pipe is easily taken out and is taken off.Therefore how a kind of delicate structure multifunctional localizer attractive in appearance, well behaved is provided is that people wish the problem that solves.

The utility model content

For overcoming the existing defective of contact system multifunctional localizer in the above-mentioned prior art, the purpose of this utility model is to provide a kind of delicate structure multifunctional localizer attractive in appearance, well behaved.

Another purpose of the present utility model is that attempt provides a kind of new connection mode that makes registration arm be difficult for taking out to take off.

For realizing above-mentioned purpose of the present utility model, this steady arm is by perpendicular section stainless steel precision casting pedestal in obtuse angle, be positioned at the pedestal angle and cast compensating device with pedestal vertical edge pivotally attached stainless steel precision, be installed in the inhibiting device in the compensating device upper hole, wire clamp assembly, the corrosion-resistant steel registration arm between compensating device and wire clamp assembly and the clevis bolt formation that is installed in the pedestal top.

Have 3 crimping pits between the attaching parts at described registration arm and two, take off to prevent that registration arm from taking out from the attaching parts at two.

Described compensating device comprises: respectively with the pedestal vertical edge on two bearing pin pivotally attached spring pull bars and connecting shaft, be the stage clip of 40-50 ° of angle with the pedestal vertical edge, be positioned at the elastic force setting nut on stage clip top, the axle that is used for being connected with registration arm, top is used to install the hole of inhibiting device.

Described inhibiting device comprises: be screwed into spacing jackscrew and spacing setting nut in the hole, and the corresponding with it positive stop lug boss that is arranged on bottom, pedestal top.

Technique scheme of the present utility model compared with prior art has the following advantages:

1, because the foundation design of this steady arm becomes obtuse angle frame shape, leaning angle on it between arm of angle and the lateral axis and inhibiting device prevent that degree of raising is relevant, its vertical edge and compensating device are hinged, two arms of angle of pedestal have been made full use of, make the whole pedestal angle that is positioned at of compensating device and inhibiting device, structure design is ingenious attractive in appearance, has dwindled the steady arm volume and weight greatly.

2, because the compensating device of this steady arm adopts the coil spring mode, and and pedestal between have two hinge-points, so flexible movements are steady, fully played elastic compensating and damping effect, alleviated the contact system that locomotive operation caused and vibrated.

3, the anti-inhibiting device of raising of this steady arm adopts boss and jackscrew mode, and is simple in structure, easily adjusts.

4, adopt 3 crimping connection modes between the attaching parts at the registration arm of this steady arm and two, because of the crimping pit is arranged,, needn't weld again so be connected firmly than hexaplanar crimping mode, thereby having overcome the disadvantage that welding is brought, registration arm is difficult for taking out and takes off.

5, because pedestal, the compensating device of this steady arm adopt whole stainless steel precision casting process, registration arm adopts corrosion-resistant steel, the defective of overcome the easy oxidation of steel casting in the past, getting rusty, rupturing, and the while has also reduced the size and the weight of steady arm.

For the easier quilt of content of the present utility model is clearly understood, describe the utility model in detail with specific embodiment with reference to the accompanying drawings.
