Abstract

The invention discloses a catenary crossing device for an underground overhead-line locomotive in a coal mine and belongs to the technical field of catenaries for underground overhead-line locomotivesin coal mines. The invention aims to solve the technical problem of providing the catenary crossing device capable of allowing the underground overhead-line locomotive to run smoothly in a crossing manner at intersections. The technical solution adopted to solve the technical problem comprises a fixed frame, a rotating frame, a crossing frame, an executive mechanism, a circuit breaker box and a controller, wherein the output end of the controller is connected to a circuit breaker in the circuit breaker box; the controller is used for controlling the executive mechanism to rotate the rotatingframe and for controlling the opening and closing of the circuit breaker; and the rotating frame and the crossing frame realize the cross-switching of two guide rails through the rotation of the rotating frame. The catenary crossing device for the underground overhead-line locomotive in the coal mine can be widely applied to the field of underground catenaries.

Description

technical field [0001] The invention relates to a catenary crosser device for a wire trolley in a coal mine, belonging to the technical field of catenary for a trolley trolley in a coal mine. Background technique [0002] When the trackless rubber-tyred wire trolley was introduced into the coal mine, in order to meet the operation requirements of the wire trolley, a catenary with a track was used. The catenary is installed in the auxiliary transportation single-track roadway of the coal mine, which realizes the smooth operation of the single-track trolley. However, in the cross roadway, the free crossing operation of the trolley cannot be realized. At present, there are two crossover technologies, which are respectively applied in the field of trolley bus wiring and rail transit. Since the trolleybus splitting and merging device adopts no track wires, and interrupts the power supply to the trolley through the crossover area, it does not meet the operating requirements of t...
