The invention discloses a vehicle base signal transponder lead screw horizontal pushing type displacement device which comprises a shell embedded in a groove in a trench. A mechanism support is arranged at the bottom of the shell and comprises a bottom plate and folding plates at the ends, and a lead screw capable of rotating around the folding plates is arranged between the folding plates. The threaded section of the lead screw is matched with a first sliding block with threads inside, and the smooth section of the lead screw is matched with a second sliding block with a smooth inside. Corresponding supporting sliding trolleys are arranged on the two transverse sides of the first sliding block and the two transverse sides of the second sliding block. A first sliding block and a second sliding block at the bottom of the scissor mechanism are hinged, and a signal transponder mounting seat is fixed at the top; flange plates at the two ends of the top of the machine shell are hinged to cover plates correspondingly, and pulleys are further arranged on the flange plates. A rope is tied outside the cover plate, one end of the rope is fixed with the cover plate, the other end of the rope bypasses the pulley to be tied on the corresponding supporting sliding trolley, the rope is linked with the signal transponder to open and close the cover plate when the signal transponder descends or ascends, and the signal transponder has the advantages of being simple, convenient, feasible, low in cost, reliable in performance and the like.
Description
technical field [0001] The invention belongs to the technical field of urban rail transit vehicle maintenance, and in particular relates to a lead screw horizontal push type displacement device for a vehicle base signal transponder. Background technique [0002] The urban rail transit vehicle train inspection warehouse is mainly used for urban rail vehicle inspection, maintenance, cleaning and operation guarantee. It is an important place to ensure the good technical status of urban rail vehicles and the normal operation of urban rail transit. Urban rail transit trains often need to run to the vehicle base parking and inspection depot for maintenance. In order to accurately, timely and reliably obtain information such as the exact position and speed of the train to achieve precise braking of the train, it is necessary to install a signal transponder in the trench of the parking train inspection warehouse. [0003] The signal transponder is located directly above the center ...
