Abstract

The utility model relates to the anti-tripping technology of train couplers, in particular to a coupler anti-tripping locking device. By the coupler anti-tripping locking device, the problem of the influence on train formation, detaching and attaching, overhauling and hump operation due to the reduction of coupling efficiency and separation efficiency of the train couplers in the using process of the conventional anti- tripping stop pin is solved. The coupler anti-tripping locking device comprises a lower lock pin, a lower lock pin rod connected with the lower lock pin and a lower lock pin rotating shaft connected with the lower lock pin rod, wherein a control table is arranged on the middle part of the lower lock pin rotating shaft; a sector is vertically fixed to the lateral surface of the left part of the lower lock pin rotating shaft, and a boss is fixed to the right lateral surface of the sector; a spring and a gasket are sleeved on the right part of the lower lock pin rotating shaft, and the gasket is positioned on the right side of the spring; and a pin hole is formed on the right part of the lower lock pin rotating shaft, and is positioned on the right side of the gasket. By the coupler anti-tripping locking device, the problem of the influence on train formation, detaching and attaching, overhauling and hump operation due to the reduction of coupling efficiency and separation efficiency of the train couplers in the using process of the conventional anti-tripping stop pin is solved effectively, and the coupler anti-bounce locking device is suitable for the tripping prevention of the couplers in the running process of trains.

Description

The anti-jump blocking device of hitch

Technical field

The utility model relates to the anti-jump technology of train coupler, specifically is the anti-jump blocking device of a kind of hitch.

Background technology

Train is in the operation way, and its two hitch often takes place to separate fault automatically, causes great safety failures such as train line is broken, emergency braking, wheel flat.For avoiding above-mentioned fault, be employed in usually and install anti-jump shotpin on the following lock pin of hitch additional and prevent that hitch from taking place to separate automatically.Practice shows, because anti-jump shotpin self structure is limit, can prevent that hitch from taking place to separate automatically though install anti-jump shotpin additional; The company that but reduces train coupler easily hangs and separation efficiency; Give thus train marshalling, get rid of extension, maintenance, hump operation and brought inconvenience, therefore, be necessary the structure of existing anti-jump shotpin is improved; Hang and separation efficiency to solve its company that in use reduces train coupler easily, so influence train marshalling list, get rid of extension, the problem of maintenance, hump operation.

Summary of the invention

The utility model is hung and separation efficiency for the company that solves existing anti-jump shotpin and in use reduce train coupler easily, so influence train marshalling list, get rid of extension, the problem of maintenance, hump operation, provide a kind of hitch anti-jump blocking device.

The utility model is to adopt following technical scheme to realize: the anti-jump blocking device of hitch, comprise down lock pin, with following lock pin bonded assembly lifet lever and with the lifet lever bonded assembly under lock pin rotating shaft; Following lock pin rotating shaft middle part is equipped with control desk; Following lock pin rotating shaft left part lateral vertical is fixed with covering of the fan, and the right flank of covering of the fan is fixed with boss; Following lock pin rotating shaft right part is with spring and pad, and pad is positioned at the spring right side; Following lock pin rotating shaft right part has pin-and-hole, and pin-and-hole is positioned at the pad right side.Said lock pin, lifet lever down are existing known configurations.Being connected between being connected between said down lock pin and the lifet lever, lifet lever and the following lock pin rotating shaft is existing known technology.

Concrete use is following: when two hitches of train connect when hanging, the hook tongue that promotes hitch turns to maximum position, and the coupler knuckle lock of hitch falls and promotes lifet lever and lock pin down, and then lock pin rotating shaft clockwise rotates maximum position under driving.At this moment, the boss on the covering of the fan of following lock pin rotating shaft just in time is stuck in the coupler body hole of hitch, and under the effect of spring, the boss on the covering of the fan tightly contacts with the coupler body hole, reaches the purpose that automatically locks down lock pin rotating shaft, prevents the train separation.When two hitches of train separate, to hold the hook shadoof and spur lock pin rotating shaft down left gently, the tension force that following lock pin rotating shaft overcomes spring is moved to the left, and the boss on the covering of the fan of following lock pin rotating shaft separates with the coupler body hole.At this moment, mention the hook shadoof, following lock pin rotating shaft rotates counterclockwise.Under the drive of following lock pin rotating shaft, following lock pin and lifet lever promote coupler knuckle lock and are up to maximum position, make hitch be in full open position of coupler.Simultaneously, following lock pin rotating shaft drives covering of the fan and boss rotates counterclockwise maximum position, and the coupler body plane contact of boss and hitch is prepared for hitch connects to hang to reach to automatically lock.Based on said process; Compare with existing anti-jump shotpin; The anti-jump blocking device of the described hitch of the utility model not only can prevent that through the structure of following lock pin rotating shaft is improved hitch from taking place to separate automatically, and makes company's extension of train coupler become more efficient and convenient with separating; The company of having improved train coupler thus hangs and separation efficiency, greatly facilitate train marshalling, get rid of extension, maintenance, hump operation.

The utility model is rational in infrastructure; Design ingenious; Efficiently solve the company that existing anti-jump shotpin in use reduces train coupler easily and hang and separation efficiency, so influence train marshalling list, get rid of extension, the problem of maintenance, hump operation, be applicable to that the train hitch that is in operation is anti-jump.
