Spray pipe adjusting mechanism on freight van compartment cleaning robot

Abstract

The invention discloses a spray pipe adjusting mechanism on a freight van compartment cleaning robot. The spray pipe adjusting mechanism comprises an installing platform, wherein a rotary seat is arranged on the installing platform, a central shaft penetrating through the installing platform is formed on the rotary seat, a first external spline is formed on the outer wall of the central shaft, a turntable sleeves and is fixed to the lower end of the central shaft in an inserted way, an installing hole is formed in the center of the turntable, a first internal spline matched with the first external spline is formed on the inner wall of the installing hole, a reset torsion spring sleeves the central shaft in an inserted way, a first arc-shaped rack and a second arc-shaped rack which protrudeare formed on the outer side wall of the turntable, the first arc-shaped rack is in meshed connection with a sector gear, the sector gear is insert-connected and fixed to a rotary shaft of a motor, the second arc-shaped rack is in meshed connection with a second rack, and a movable seat is fixedly connected to the second rack. The spray pipe adjusting mechanism can achieve reciprocating spray pipe flushing without switching of the rotary direction of the servo motor and save the cost.

Description

Technical field: [0001] The invention relates to the technical field of robots, in particular to a nozzle adjustment mechanism 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
