Abstract

The invention discloses a rail grasping device of a catenary vehicle ladder. The rail grasping device comprises a base, and clamping claws mounted on the base in a hinged manner, wherein the base comprises two parallel side plates which are arranged at intervals, and a top plate mounted between two side edges; the clamping claws are mounted between the two side plates, and a pull rod is movably mounted on the top plate; a push plate which can be applied on the clamping claws is arranged at the bottom of the pull rod; a cam is mounted at the top of the pull rod and can rotate relative to the pull rod; a transmission sleeve is mounted on the pull rod between the cam and the base in a sleeving manner; a spring sleeve is arranged on an inner end surface close to one side of the push plate, of the transmission sleeve; a bracket is also mounted on each side plate of the base, and a hold hoop with a fastening and fixing function is mounted at the tail end of each bracket. The rail grasping device of a catenary vehicle ladder, provided by the invention, is simple in structure, and can effectively prevent the catenary vehicle ladder from overturning; through the rail grasping device, the operation time is shortened, the labor strength of workers is reduced, and the rail grasping device is easy to repair and maintain, so that the defects that a conventional contact-line vehicle ladder is poor in stability, low in safety and inconvenient to use are overcome.

Description

technical field [0001] The invention relates to the technical field of an electrified railway catenary maintenance car ladder, in particular to a catenary car ladder rail grabber. Background technique [0002] The catenary is the main frame of the railway electrification project, and it is a special form of transmission line erected along the railway line to supply power to the electric locomotive. The catenary vehicle ladder is the main tool for catenary construction and maintenance and climbing operations. It mainly consists of ladders on both sides to form a frame part. The top of the frame is equipped with a top seat and a protective fence. [0003] As we all know, the faster the train travels, the greater the centrifugal force generated when passing through the curve. In order to ensure the safety of the train operation, the outer rail in the curve section has a super-high design, such as the radius of the curve is 1200m, and the outer rail is super high. Possibly up t...
