A kind ofly be used for the latching device that railway train tail wind pressure alarm moves trunking

Technical field

The present invention relates to a kind of latching device that railway train tail wind pressure alarm moves trunking that is used for, relate in particular to a kind of railway wireless data communication field train tail wind pressure alarm that is used for and move relay host and the fixing latching device of train.

Background technology

The railway freight traffic train is behind cancellation guard's van (vehicle commander), for grasping last vehicle of train compartment situation 800MHz row tail wind pressure alarm equipment has been installed, but there is feeble field in 800MHz row tail pressure warning device in the tunnel, therefore need a trunking to be installed, guarantee the normal transmission of wind pressure alarm signal at the train middle part; In the existing railway freight traffic train, row tail wind pressure alarm moves trunking and is contained on the equipment such as flat truck, spacious box car, truck tanker, the latching device that original row tail wind pressure alarm moves trunking comprises hook, tooth piece and metal semi arch box, the connection mode of its latching device and goods transport train is: hook is hung on the staircase of lorry, by the tooth piece metal semi arch box of embracing the staircase stull is blocked, realize the locking of itself and lorry; But this kind locking mode only is suitable for and has staircase and the staircase stull is the part vehicle of pipe shape, existing railway freight traffic train has tens of kinds, resemble in flat truck, special purpose vehicle etc. and this kind latching device can not be installed on not with the vehicle of staircase, and staircase also divides band iron type, angle iron-type, tubular type good several, size is disunity also, the latching device compatibility that makes original row tail wind pressure alarm move trunking is very poor, can not be fit to various lorries; In addition, the staircase on the railway truck generally is installed in the rear and front end face of lorry, has influence on the acceptance and the transmission of mid-category devices signal.

Summary of the invention

The objective of the invention is to develop a kind of compactness rational in infrastructure, easy to loading and unloading, latching device that train tail wind pressure alarm that be fit to various lorries moves trunking.

Technical scheme of the present invention is: a kind ofly be used for the latching device that railway train tail wind pressure alarm moves trunking, comprise catch gear and anti-actuation mechanism, it is characterized in that: row tail wind pressure alarm moves relay host one side anti-actuation mechanism is housed, and opposite side is equipped with catch gear; Anti-actuation mechanism is provided with manual briquetting, and manually briquetting is clamped on by screw and draws the post upper end, draws post and is contained in the guide pin bushing by locking mother, and guide pin bushing is connected with main frame, and stage clip is housed in the guide pin bushing, and grab is fixed on the bottom of drawing post; The catch gear of main frame opposite side is connected with relay host, catch gear is provided with pressing plate, key hole is positioned at the front middle part of pressing plate, pressing plate with withhold hook and be connected by hinge axis, withhold that hook is inboard uses the rivet shell fragment, the inside of pressing plate is fixed with the sliding sleeve group by nut, in the lock core group is arranged, spring is equipped with in both sides, and dead bolt group rear portion is connected with the lock core group.

The catch gear that the present invention adopts moves row tail wind pressure alarm on the foot of ladder that relay host is locked at various freight train middle part, and the anti-actuation mechanism of main frame lower-left side then rotatablely moves up and down by drawing a post, finishes and being connected or disengaging of train foot of ladder; The present invention's compactness rational in infrastructure, sturdy and durable, the train tail wind pressure alarm device can be clamped on the various lorries easily.
