Description

Be used for abluent reciprocal wiper mechanism of locomotive

Technical Field

The utility model relates to the technical field of maintenance of rail transit equipment, in particular to a reciprocating cleaning mechanism used in the field of locomotive cleaning.

Background

In the field of rail transit, according to the car body maintenance requirement of a C6 maintenance flow of the HXD1 alternating current electric locomotive, all parts on the car body are removed before maintenance, and then the car body is cleaned so as to facilitate polishing and paint spraying in the next working procedure. The surface of the vehicle body is generally initially cleaned by an automatic cleaning machine, and six surfaces outside the vehicle body are all required to be covered during cleaning.

For cleaning the side of locomotives, there are currently a variety of types of automatic cleaning mechanisms, such as automatic spray cleaning mechanisms: the automatic spraying type cleaning mechanism is used for cleaning a locomotive through a spraying system, and a nozzle or a spray head is arranged in the system to spray cleaning liquid or clean water. Such mechanisms are commonly used for rapid wetting and flushing of the entire locomotive car or large area. Automatic spray cleaning mechanisms generally have the advantage of being efficient and time-saving. However, in the conventional automatic spray type cleaning mechanism, a plurality of groups of fixed spray heads are generally used for cleaning by covering the whole side surface height range. The mode needs a plurality of nozzles to be densely arranged to cover the cleaning range of the side face, more spray heads have high requirements on flow parameters required by the water pump, the pressure of the nozzles can be reduced, the water consumption during cleaning is high, and the cleaning effect is difficult to ensure. At present, development of a locomotive surface cleaning mechanism which is efficient, saves resources and can ensure cleaning effect is urgently needed.

Disclosure of utility model

The utility model aims to provide a reciprocating cleaning mechanism for locomotive cleaning, which solves the problems of large coverage area of a spray head, high water pressure requirement on a water pump and huge water consumption in the conventional locomotive side surface cleaning, and can realize the coverage cleaning of a side surface range by only using fewer nozzles to reciprocate up and down when the locomotive side surface cleaning is realized. The utility model adopts the reciprocating cleaning structure with the spray heads vertically arranged and driven by the actuator device, can clean the side surface of the whole locomotive with fewer spray heads, has low requirement on the flow of the water pump, and can improve the cleaning pressure. Greatly reduces the water consumption, has better cleaning effect, saves energy and protects environment.

In order to achieve the above object, the present utility model provides the following technical solutions:

A reciprocating cleaning mechanism for cleaning locomotive is composed of actuator, nozzle tube set, and guide mechanism. The actuator device is vertically fixed on the side surface of the automatic cleaning machine. The speed regulating valve is arranged at an oil inlet and an oil outlet of the actuator device, the nozzle pipe group is connected with a piston rod of the actuator device, the guide mechanism is fixed on the side surface of the automatic cleaning machine and is connected with the nozzle pipe group, and the output end of the actuator device drives the nozzle pipe group to lift along the guide mechanism.

For the nozzle pipe group of the technical scheme, the nozzle pipe group mainly comprises a plurality of nozzles and a pipeline, wherein the nozzles are vertically arranged on the pipeline. This design ensures that the nozzle can cover the entire side area of the locomotive for cleaning during reciprocation without the need for an additional number of spray heads.

The guiding mechanism of the technical scheme mainly comprises a guide rail, a wheel shaft, a roller, a cotter pin and a connecting device. The guide rail is fixed on the automatic cleaning machine, one end of the connecting device is installed on a pipeline of the spray nozzle pipe group, the other end of the connecting device is fixed on the wheel shaft, the wheel shaft is connected with the roller through the cotter pin, and the roller rolls in the guide rail long groove.

The speed regulating valve can be adjusted according to actual needs to control the movement speed and the movement force of the actuator device, so that the speed regulating valve is suitable for different cleaning work requirements and is an adjustable proportional valve. Therefore, in the cleaning process, the nozzle tube group can reciprocate at proper speed and strength, and the optimal cleaning effect is achieved.

The design of the guide rail and the wheel axle of the guide mechanism can ensure that the nozzle pipe group has stable guiding and supporting functions in the reciprocating motion. The rolling of the roller enables the nozzle tube group to stably move along the long groove of the guide rail, thereby ensuring the accurate alignment of the nozzle and repeated cleaning in the cleaning process.

For actuator devices in the form of hydraulic cylinders, air cylinders or electric pushrods, a suitable driving mode can be selected according to actual requirements. Therefore, the automatic control device is flexibly applicable to different cleaning mechanisms and realizes automatic control of the cleaning mechanisms.

Instead of a roller-type guide, other types of guide such as linear slides may be selected. In this way, different guiding mechanisms can be selected according to the actual situation so as to meet the specific requirements and operating conditions of the cleaning mechanism.

Compared with the existing cleaning mode that a plurality of groups of fixed spray heads cover the whole side surface height, the utility model uses fewer spray heads to lift reciprocally, reduces the flow requirement on the water pump, and is beneficial to increasing the cleaning pressure. The water consumption is reduced, and the environment is protected. Higher cleaning pressure and more cleaning times are beneficial to improving the cleaning effect. Through the improvement, the reciprocating cleaning mechanism for locomotive cleaning can provide a more efficient, water-saving and energy-saving cleaning scheme, meets the requirement of cleaning the side surface of the locomotive, and has better cleaning effect and environmental protection performance.

As shown in fig. 1, which is a frame structure diagram of an automatic cleaner, a plurality of pairs of reciprocating cleaning mechanisms are symmetrically arranged on the automatic cleaner, and the reciprocating cleaning mechanisms reciprocate up and down on the cleaner. The action process is as follows: as shown in fig. 2, the actuator device 1 extends out, and the piston rod of the actuator device 1 drives the nozzle pipe group 3 positioned below to descend, so that the nozzle of the nozzle pipe group 3 is lower than the lowest point of the side surface of the vehicle body; the actuator device 1 is retracted, and the piston rod of the actuator device 1 drives the nozzle pipe group 3 positioned below to ascend, so that the nozzle of the nozzle pipe group 3 is higher than the highest point of the side surface of the vehicle body. The guide mechanism 4 is connected with the nozzle pipe group 3 and provides vertical guide for the nozzle pipe group 3. The speed control valve 2 is adjusted to control the expansion and contraction speed of the actuator device 1. In the forward process of the gantry cleaning machine, the nozzle pipe group 3 is lifted up and down to clean and cover the whole side surface of the locomotive body.

The actuator device 1 can realize telescopic action by connecting a hydraulic system. The hydraulic system may include hydraulic pumps, hydraulic oil lines, hydraulic control valves, and the like to provide the desired pressure and flow. The telescopic speed of the actuator device 1 can be realized by adjusting the valve opening of the speed regulating valve 2, so that different cleaning requirements and working conditions can be met.
