The insulator on the top of the motor train unit serves as a main insulating device on the top of the motor train unit, and the reliability of the insulator directly influences the normal operation of the motor train unit. The roof insulator can receive the influence of factors such as granule dust under natural environment, makes the insulator surface deposit filth to increase the probability that the insulator takes place the pollution flashover, and then bring very big hidden danger for the operation safety of EMUs. Therefore, in the first-level overhaul range of the motor train unit, the cleaning work of all types of insulators on the roof of the motor train unit is included.

The traditional working mode of cleaning the insulator is manual cleaning, the cleaning effect is poor, and the cleaning efficiency is low.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

As shown in fig. 1 and 2, fig. 1 is a view of an application scenario of the insulation column cleaning and positioning system in the present embodiment, and fig. 2 is a partially enlarged view of a point a in fig. 1, in the figure, a locomotive 100 is located at a station to be cleaned, a guide rail 200 and a cleaning arm 300 sliding on the guide rail 200 are arranged above both sides of the locomotive 100, and the cleaning arm 300 can realize initial positioning by moving to a specific position along the guide rail 200 to correspond to an insulation column 110 on the top of the locomotive 100.

When the mounting seat 301 of the cleaning arm 300 moves to the position corresponding to the proximity switch, the driving of the mounting seat 301 is cut off and stopped, so that the cleaning arm 300 stays at the position corresponding to the insulation column 110, by mounting the proximity switch on the guide rail 200 and making the proximity switch correspond to the position of the insulation column 110.

Optionally, in this embodiment, the proximity switch needs to use an active proximity switch, such as an eddy current proximity switch, a hall proximity switch, or an electro-optical proximity switch. As shown in fig. 3, the proximity switch is selected as an eddy current type proximity switch, when a conductive object approaches the proximity switch, an eddy current is generated inside the object, and the eddy current reacts on the proximity switch to change circuit parameters inside the switch, so that whether the conductive object moves close is identified, and the on or off of the switch is controlled. The vortex proximity switch is installed on an installation seat 301, a plurality of locators 302 are installed at equal intervals in the length direction of the guide rail 200, the locators 302 are controllable on-off conductors capable of being matched with the vortex proximity switch, a control part of the locators 302 are conducted (see filling parts in fig. 3), and when the installation seat 301 moves to the conducting locators 302, the locators 302 enable the vortex proximity switch to generate a vortex to achieve on-off control when approaching the vortex proximity switch. When the conductive retainer 302 corresponds to the insulation column 110, only the portion of the retainer 302 can generate an eddy current with the eddy current type proximity switch and generate a detection signal, and the detection signal is converted into a driving signal for the mounting base 301, so that the mounting base 301 can be controlled to stop at a predetermined position to realize positioning.

Optionally, as shown in fig. 4, the insulation column cleaning and positioning system of this embodiment further includes a positioning detection module 401, an adder 402, a PLC control module 403, and a power supply module 404, where the positioning detection module 401 is configured to detect a position of the locomotive 100, assist the locomotive 100 in positioning and stopping, and output a detection signal, the adder 402 counts and accumulates the detection signal output by the positioning detection module 401 once when receiving the detection signal, and generates a numerical signal, a default value of the adder 402 is 0, the PLC control module 403 obtains the numerical signal to generate a control signal, and the power supply module 404 receives the control signal to control the positioners 302 to form an on-off state according to a specified arrangement.

When the locomotive 100 enters a cleaning area and a first carriage enters a designated position, the positioning detection module 401 detects that a feedback signal is sent to confirm that the first carriage enters the designated position, for example, the feedback can be realized by adopting a sound-light alarm and the like, so as to assist in positioning the locomotive 100, and meanwhile, the positioning detection module 401 can also generate a corresponding detection signal, because the default value of the adder 402 is 0, when the detection signal of the first carriage enters the adder 402, the output numerical signal becomes "1", and the PLC control module 403 receives the numerical signal "1" and executes a user program preset in the PLC control module 403 to output a control signal, wherein the control signal corresponds to the numerical signal "1" to control the on-off of the positioner 302, such as the positioners 302 with the numbers "a and f" are opened, and the rest are all closed; after the first car is cleaned, the locomotive 100 moves to make the second car enter a designated position, at this time, the positioning detection module 401 repeats the positioning detection operation, the numerical signal output by the adder 402 becomes "2", the control signal output by the PLC control module 403 corresponds to the numerical signal "2" to control the on/off of the positioner 302, for example, the positioners 302 with the numbers "d and k" are opened, and the rest are all closed. Self-locating cleaning of the insulator posts 110 at the tops of all cars of the locomotive 100 can be accomplished by simply loading into the PLC control module 403 the user control program stored with locators 302 corresponding to different car section numbers of the locomotive 100.

The specific control method of the insulating column cleaning and positioning system comprises the following steps:

step 1), controlling the locomotive 100 to enter a cleaning area and slowly approach a positioning detection module 401;

step 2), the positioning detection module 401 detects that the locomotive 100 enters a fixed point position, generates a feedback signal and a detection signal, outputs the feedback signal to the audible and visual alarm to trigger audible and visual alarm, and stops positioning the locomotive 100;

step 3), after receiving the detection signal, the adder 402 counts and accumulates the signal, generates a numerical value signal and outputs the numerical value signal, wherein the numerical value of the numerical value signal is the registered numerical value plus 1, the default value of the registered numerical value is 0, and the numerical value signal generated each time covers the previous registered numerical value;

step 4), the PLC control module 403 executes a corresponding user program and outputs a control signal after acquiring the numerical signal;

step 5), the power supply module 404 receives the control signal and then controls different on-off states of the positioner 302, so that the positioner 302 in the open state corresponds to the positioned insulating column 110 at the top of the locomotive 100 carriage;

step 6), controlling the mounting seat 301 to travel along the guide rail 200 until the mounting seat 301 approaches the first opened locator 302, and then driving the cleaning arm 300 to start cleaning; the installation seat 301 is controlled to start to travel along the guide rail 200 again after the cleaning arm 300 finishes cleaning work through delay setting until the cleaning work of the carriage is finished;

and 7), controlling the locomotive 100 to slowly move to enable the cleaned carriage to move out of the cleaning area, and repeating the steps 2) to 6) until the locomotive 100 finishes cleaning.
