Abstract
The utility model discloses an electrified rail connecting net steel tube rigid cross beam overhanging base, in order to improve the reliability and the stability of suspending installation, and in addition, the construction is simple and convenient and the cost is effectively reduced. The electrified rail connecting net steel tube rigid cross beam overhanging base comprises an overhanging base body (10), a fixed hoop (11) and a U-shaped screw rod (20), wherein the upper part of the U-shaped screw rod (20) upwards penetrates through the fixed loop (11) and a mounting hole in the overhanging base body (11), an upper adjusting nut (21) and a lower adjusting nut (22) are respectively arranged on screw sections above the overhanging base body (10) and below the fixed hoop (11); the bottom of the U-shaped screw rod (20) is sleeved with a ball eye (30).
Description
Technical field
The utility model relates to electrification railway contact net, particularly the hard crossbeam suspention of a kind of electrification railway contact net steel pipe base.
Background technology
Along with the construction of the develop rapidly of China's electrified railway, particularly high-speed electric railway and the requirement of station landscape, in electrification railway contact net, the hard cross beam type headspan suspension of steel pipe is more and more adopted.Headspan suspension is the lateral support equipment of field, station, multiply road contact suspension, by the pillar of electric railway both sides with hang over the horizontal catenary on pillar, their part composition of upper and lower part static line and support and connection.
At present, the suspention link of parts is installed on the hard crossbeam of electrification railway contact net steel pipe, to adopt on angle steel to weld round steel, its mounting means is to adopt two straight bolts on angle steel, to weld the upper and lower body of round steel, after stepping up, be fixed on the hard crossbeam of steel pipe, by the ears suspension insulator of bottom.Because the hitch point of this suspention link is fixed, often need increase tension adjustment part to adapt to actual requirement in the bottom of insulator, therefore not only construct loaded down with trivial details, and cause cost to increase.
Utility model content
Technical problem to be solved in the utility model is to provide the hard crossbeam suspention of a kind of electrification railway contact net steel pipe base, to improve, hangs the reliability and stability of installing, and easy construction, and effectively reduces costs.
It is as follows that the utility model solves this technical problem adopted technical scheme:
The hard crossbeam suspention of electrification railway contact net steel pipe of the present utility model base, it is characterized in that: it comprises suspention base body, fixing anchor ear and U-shaped screw rod, the top of U-shaped screw rod is upward through the mounting hole on fixing anchor ear, suspention base body, and on the thread segment more than suspention base body, below fixing anchor ear, setting nut, lower setting nut is set respectively; The bottom suit ball-eye of U-shaped screw rod.
The beneficial effects of the utility model are, have improved and have hung the reliability and stability of installing, and easy construction, and can effectively reduce costs, rational in infrastructure, can be widely used in during electrified railway that Speed Increased Reformed and landscape have relatively high expectations builds.
Accompanying drawing explanation
This specification sheets comprises following four width accompanying drawings:

Member shown in figure and corresponding mark: suspention base body 10, fixing anchor ear 11, U-shaped screw rod 20, upper setting nut 21, lower setting nut 22, ball-eye 30, pestle head suspension insulator 31, earrings suspended insulator 32, link plate 33, band ear steady ring wire clamp 34, the hard crossbeam steel pipe 40 of contact system.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
With reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the hard crossbeam suspention of electrification railway contact net steel pipe of the present utility model base comprises suspention base body 10, fixing anchor ear 11 and U-shaped screw rod 20, the top of U-shaped screw rod 20 is upward through the mounting hole on fixing anchor ear 11, suspention base body 10, and at suspention base body more than 10, setting nut 21, lower setting nut 22 are set respectively on the thread segment of fixing anchor ear below 11.Tightening setting nut 21, lower setting nut 22 can be fixedly mounted in suspention base body 10 on the hard crossbeam steel pipe 40 of contact system.Because suspention base bottom is connected with the hard crossbeam steel pipe 40 of contact system by fixing anchor ear 11, increased area of contact, can effectively prevent that the load such as wind, vibration from making to suspend in midair base and collecting together along crossbeam.
With reference to Fig. 1, by changing the locked position of upper setting nut 21, lower setting nut 22, can adjust within the specific limits setting height(from bottom), without increasing tension adjustment part, therefore easy construction, and can effectively reduce costs; Suspention base can be along the hard crossbeam horizontal adjustment of steel pipe installation site, makes each hitch point height of top positioning rope of contact system headspan suspension consistent, and constructability is installed, safe and reliable.
With reference to Fig. 1 and Fig. 4, the bottom suit ball-eye 30 of described U-shaped screw rod 20, ball-eye 30 is connected with pestle seat insulator, can eliminate bottom torque load and make to suspend in midair torsion, the dislocation that base produces.With reference to Fig. 4, pestle seat insulator comprises the pestle head suspension insulator 31 and the earrings suspended insulator 32 that are fixedly connected with, and link plate 33, mounting strap ear steady ring wire clamp 34 on link plate 33 are installed in earrings suspended insulator 32 lower ends.Pestle seat insulator is by link plate 33 and the top positioning rope with ear steady ring wire clamp 34 fixing contact system headspan suspensions.By adjusting the upper setting nut 21 on U-bolt, the locked position of lower setting nut 22, can adjust the height of pestle seat insulator, and the bottom of pestle seat insulator can be connected to tensioning.
Some principles of the hard crossbeam suspention of the above the utility model electrification railway contact net steel pipe that just explains through diagrams base, be not the utility model to be confined to shown in and in described concrete structure and Applicable scope, therefore the corresponding modify being likely utilized every and equivalent, all belong to the scope of the claims that the utility model is applied for.
