Description

Intelligent adjusting device for pantograph Technical Field The utility model relates to the technical field of pantographs, in particular to an intelligent pantograph adjusting device. Background The pantograph is an electric device arranged on the top of a rail vehicle such as an electric locomotive and a motor train unit, and is used for receiving electric energy through contact with a contact net so as to provide power for running the vehicle. When the existing intelligent pantograph adjusting device is used, the pantograph arm is pushed through the elasticity of the spring, however, strong wind force is generated when a vehicle runs to push the pantograph arm, so that the spring is compressed, meanwhile, the problem that the pantograph arm and the top lapping line cannot be lapped due to the compression of the pantograph arm can be solved, and meanwhile, the graphite plate needs to be replaced after being used for a long time, and the replacing method is very troublesome. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides the intelligent pantograph adjusting device which has the advantages of spring force adjustment and convenience in replacing a graphite plate, and solves the problems proposed by the background art. The intelligent pantograph adjusting device comprises a base, wherein a first connecting rod is rotationally connected to the top of the base, a second connecting rod is rotationally connected to the top of the first connecting rod, an arch wall is rotationally connected to the top of the second connecting rod, a motor is fixedly arranged on the outer wall of the base, a sliding groove is fixedly arranged on the top of the base, a sliding frame is slidingly connected to the top of the sliding groove, a spring seat is fixedly arranged on the outer wall of the sliding frame, a thrust spring is fixedly arranged on the outer wall of the spring seat, a threaded rod is fixedly arranged on an output shaft of the motor, a limit rod is fixedly arranged on the inner wall of the base, a fixing shell is fixedly arranged on the outer wall of the arch wall, a graphite plate is arranged on the top of the fixing shell, a mounting plate is fixedly arranged at the bottom of the graphite plate, an insert block is slidingly connected to the inner wall of the fixing shell, a threaded column is rotationally connected to the outer wall of the insert block, a slot is formed in the outer wall of the mounting plate, and a rotating head is fixedly arranged on the outer wall of the threaded column.
