Nozzle reciprocating device on cleaning robot of freight car

Abstract

The invention discloses a nozzle reciprocating device on a cleaning robot of a freight car. The device comprises a mounting platform where a rotating seat is inserted; a central shaft that goes through a lower end surface of the mounting platform is formed on the rotating seat; a lower end of the central shaft is fixed by a rotating disk in a sleeved mode; the central shaft is sleeved by a reset torsional spring; a first fixing hole is formed in the rotating disk; a second fixing hole is formed in a lower end surface of the mounting platform; two ends of the reset torsion spring are fixed on inner walls of the first fixing hole and the second fixing hole; a first arc rack and a second arc rack which are projecting are formed on an outer side wall of the rotating disk; the first arc rack ismeshed and connected with a sector gear which is inserted and fixed on a rotating shaft of a motor; the second arc rack is meshed and connected with a second rack which is fixedly connected with a moving seat. The invention can realize the reciprocating flushing of the nozzle without the rotation direction switch of the servo motor, saves the cost and has high working efficiency.

Description

Technical field: [0001] The invention relates to the technical field of robots, in particular to a nozzle reciprocating device on a freight car cleaning robot. Background technique: [0002] A robot is a machine device that performs work automatically. At present, a large number of long-distance cargo transportation in my country is mainly undertaken by railway transportation, and the annual cargo turnover of railways accounts for 55% of the total cargo turnover of the whole society. In the past, the cleaning work of freight train carriages has been done manually, which is relatively labor-intensive for workers, and the use of some chemicals for disinfection will cause harm to the human body, so now the carriage cleaning work is gradually replaced by cleaning robots Manual work. The cleaning robot is generally provided with a nozzle, and the use of the nozzle for flushing requires that the nozzle on the cleaning robot be provided with a reciprocating structure, including l...

In the past, the cleaning work of freight train carriages has been done manually, which is relatively labor-intensive for workers, and the use of some chemicals for disinfection will cause harm to the human body, so now the carriage cleaning work is gradually replaced by cleaning robots manual work

The cleaning robot is generally provided with a nozzle, and the use of the nozzle for flushing requires that the nozzle on the cleaning robot be provided with a reciprocating structure, including linear reciprocation and rotary reciprocation. The rotary reciprocation is generally controlled by a servo motor, and the servo motor itself The cost is high. At the same time, the servo motor needs to be switched in the forward and reverse directions, which is easy to be damaged. It is necessary to improve it
