Abstract

The utility model relates to a double connection train coupler, and belongs to the field of wheel transportation. and the train coupler is characterized in that a lock hole is formed on the side wall of the coupler head, and a coupler knuckle and a cavity are formed at the front end of the coupler head; a hollow cavity is formed at the bottom part of the cavity, and a spring is arranged inside the hollow cavity; an inverted T-shaped jacking block arranged in the hollow cavity is connected with a spring; a lock hole is formed on the side surface of the coupler knuckle; a groove is formed in the middle of the lock core, and an upper groove is formed in the position that one end of the lock core and the groove form an angle of 90 degrees; the groove is corresponding to the end part of the T-shaped jacking block horizontal plane; a spring is embedded in the lock core, and a groove is formed at one end head of the lock core; and the hook head and the coupler knuckle are integrated. The coupler provided by the utility model avoids unhooking and separation and has locking and closing function, and a non-professional can not unlock, thereby achieving the advantages of safety and stability in vehicle operation and high safety factor. Besides, the pulling tonnage can be increased by thousand times, automatic connection, simple and convenient operation, wear-resistance, low cost, and general use in coach and van can be realized, and the coupler type is unified.

Description

Dual link is train coupler arranged

One, technical field

It is train coupler arranged that the utility model relates to a kind of dual link, belongs to the vehicular transport field.

Two, background technology

At present, institute's use hitch on the China railways, disclosed automatic car coupler in " maintenance of railway vehicle structure and equipment " that China Railway Press publishes, that adopts on the lorry has No. two, ten No. three, what adopt on the passenger vehicle is No. one, ten No. five, along with the raising of train speed and the increase of traction tonnage, intensity to hitch is had higher requirement, No. one and No. two hitches can not adapt to requirements on transport, eliminate gradually, now ten No. three higher and ten No. five hitches of intensity that adopt, by gib head, the hook tongue, the hook body, the hook tail, lifet lever, compositions such as coupling lever, this kind hitch and hook tongue and hook tongue link together, and are unidirectional connection, and anyone needs only one and carries coupling lever, hitch will produce to break off relations and separate, dangerous, have an accident, and do not have too high tractive force, tonnage is little.

Three, summary of the invention

The purpose of this utility model is to provide the separation of can not breaking off relations naturally of a kind of hitch, the safety factor height, and the traction tonnage is big, and the dual link with dual link and locking function is train coupler arranged.

Technical solution: have lockhole on the gib head sidewall, gib head front end one side is provided with the hook tongue, opposite side is provided with and the corresponding cavity of hook tongue, the bottom, chamber is provided with cavity, be provided with spring in the cavity, the madial wall of cavity is provided with cavity, be provided with down " T " font top iron in the cavity, the vertical surface of " T " font top iron places cavity bottom and is connected with spring, hook tongue sidewall is provided with lockhole, and the gib head of two mutual connections and hook tongue are by the lock core captive joint, and the middle part of lock core is provided with groove, lock core one end and be provided with upper groove in the position at an angle of 90 with groove, groove is corresponding with " T " font top molten iron flat end, is set with spring on the lock core, and lock core one termination is established and had groove, another termination is provided with draw ring, and gib head and hook tongue are one.

Be positioned at position, lockhole outer ring on the gib head and be provided with boss.

The gib head in the hook tongue outside is provided with S. A., and axle is provided with turnover panel.

The utility model forms the dual link form because two gib heads interconnect, and gib head uses mutually by lock pin with the hook tongue and lock, so hitch can not produce the unhook separation phenomenon, the locking function is arranged, not that personnel can not untie lock in the industry, safety and stability during vehicle operating, safety factor height, and the traction tonnage can increase more than thousand times, can realize automatic engagement, simple to operation, anti-damage, cost are low, and the visitor, lorry is general, unified the hitch type.
