The connecting device is provided with a locking drum and a horizontal channel of a positioner positioning device with a supporting structure for contact lines. The limiting device which is hinged with the connecting device vertically rotates. The positioning device is composed of the fixedly connection of a hinged arm, a positioning tube, and a positioning elbow; the positioning device which is hinged with the limiting device can horizontally rotate. An adjustable positioning device controls the anticlockwise rotating angle of the limiting device and controls the lifting quantity of the utility model. The utility model is characterized in that the utility model can adjust and change the lifting quantity according to different operating requirements. The loop resistance of the connecting part between the utility model and the positioning device of the utility model is small; the connecting part is not easy to sinter or burn out due to the short circuit of a loop. The phenomenon of the eccentric abrasion of a contact conductor and impact between the pantograph of a locomotive and a limiting positioning device is not easy to take place, with even springiness of the contact conductor and no hard points.
Description
The utility model relates to the device of a kind of electrification railway contact net with qualification contact wire level attitude.
At present China's electrification railway contact net steady arm of being used to limit the contact wire level attitude use more a kind of be by location hook, have the registration arm of certain bending angle and the steady arm that the location elbow of wire clamp constitutes be housed, the steady arm location hook is hooked on the steady ring on the supporting construction of contact system during use, and the wire clamp on the elbow of location is clamped in the contact wire.Steady arm and supporting construction adopt the shackle connection mode, and its area of contact is little, and loop resistance is big, in case system is short-circuited and easily blows with the junction sintering or with location hook and accidents caused.Steady arm does not have the lifting inhibiting device, dynamically amplitude is big, contact wire is subjected to the effect of dynamic lifting power of motorcycle pantograph or other reasons causes that vibration makes contact wire transition lifting and take place the service life that the eccentric wear phenomenon has a strong impact on contact wire when locomotive is run at high speed, when serious even steady arm wire clamp and pantograph percussion phenomenon take place and cause train operation accident.The steady arm of this structural shape generally only is used for the locomotive speed per hour at the contact system below 140 kilometers/hour for above-mentioned reasons.
Along with the development of China's electrified railway and improving constantly of motor supply shop's vehicle speed, the steady arm of this structural shape is difficult to adapt to the operating needs that improves constantly.
The purpose of this utility model provides a kind of simple in structure, the spacing steady arm of electrification railway contact net that the uplift of steady arm amount can regulate, change according to operating needs.
Electrification railway contact net with spacing steady arm by have the ancient adaptor union of contact system supporting construction steady arm registration device hugging and locking, with the adaptor union end hinged vertically rotating have the steady arm articulated jib and with articulated jib accompany the limiting bracket of certain angle limiting device, constitute with the hinged steady arm that is formed by fixedly connecting by articulated jib, the registration arm that has certain bending angle, location elbow that horizontally rotates of limiting device, the adjustable pushing tow head of screw-on is housed on the check bracket, the pushing tow head cooperate with adaptor union edge face pushing tow limiting device is rotated counterclockwise spacing.Screw adjustable pushing tow head scalable and change the angle that limiting device rotates counterclockwise, and then regulate, change the lifting amount of steady arm.On the location elbow of steady arm the wire clamp locating dowel pin is housed, wire clamp is loaded on the elbow of location by locating dowel pin.
Electrification railway contact net is that the adjustable pushing tow head of screw-on of limiting device has the locking positioning device with further improving of spacing steady arm, with the lifting amount that prevents that the pushing tow head is loosening, displacement changes spacing steady arm voluntarily.
The electrification railway contact net that the utility model provides is simple with spacing locator structure, and cost is low, is convenient to extensive employing.Can regulate the lifting amount that changes steady arm according to different operatings needs, so can satisfy the operating needs of different speed of a motor vehicle contact systems.Adopt folder to hold connection mode between the steady arm registration device of spacing steady arm and contact system supporting construction, the junction area of contact is big, and loop resistance is little, and connecting portion was difficult for sintering taking place or blowing when loop was short-circuited.Reduced the eccentric wear phenomenon of or too small generation excessive because of the uplift of steady arm amount.The generation of motorcycle pantograph percussion steady arm wire clamp phenomenon, or produce hard spot to contact wire adverse effect in service life because of destroying the contact wire uniform elastic.
Accompanying drawing is embodiment of the present utility model, further specifies the utility model below in conjunction with embodiment.
