Spraying pipe adjusting mechanism for freight compartment cleaning robot

Abstract

The invention discloses a spraying pipe adjusting mechanism for a freight compartment cleaning robot. The spraying pipe adjusting mechanism for the freight compartment cleaning robot includes a mounting platform, a rotary base is inserted in the mounting platform, a central shaft penetrating out of the lower end face of the mounting platform is shaped on the rotary base, the lower end of the central shaft is fixed to a rotary disc in an inserted and sleeved mode, the central shaft is inserted in and sleeved with a restoration spring, the two ends of the restoration spring are fixed to the rotary disc and the mounting platform respectively, a first arc rack and a second arc rack are shaped on the rotary disc, the first arc rack mesh with a first rack in a meshing mode, an insertion groove is formed in one end of the first rack, a piston rod of a drive cylinder is inserted into the insertion groove, the piston rod of the drive cylinder and the first rack are inserted into and sleeved with pressure springs, the two ends of the pressure springs are fixed to the outer wall of the piston rod of the drive cylinder and the outer wall of the first rack respectively, the second arc rack meshes with the second rack, and a movable base is fixed to the second rack. By the adoption of the praying pipe adjusting mechanism for the freight compartment cleaning robot, washing of a spraying pipecan be conducted repeatedly without switching the rotation direction of a servo motor, the cost is saved, and the working efficiency is high.

Description

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

Problems solved by technology

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
