Description

A multi-functional dust removal gun suitable for rail work vehicles Technical Field

[0001] This utility model belongs to the technical field of rail work vehicles, specifically relating to a multi-functional dust removal gun suitable for rail work vehicles. Background Technology

[0002] The cleaning of air filters on current railway track maintenance vehicles does indeed face a series of technical challenges and limitations. Traditional dust removal methods, such as manual brushing, while relatively straightforward, have a significant drawback: they are time-consuming, often requiring more than 30 minutes for a single cleaning session. This is undoubtedly a heavy burden for railway maintenance teams that prioritize efficiency. Furthermore, manual brushing necessitates frequent replacement of consumables, such as brushes, which further increases operating costs.

[0003] On the other hand, while using an external high-pressure blower as a relatively portable dust removal solution reduces manpower to some extent, it also presents significant problems. Firstly, the high-pressure blower, as an additional piece of equipment, occupies valuable space on the work vehicle, posing a challenge given the already limited space available. Secondly, the maintenance of the high-pressure blower is a considerable expense, increasing overall operating costs. More importantly, limited by the high-pressure blower's typically lower output pressure (usually not exceeding 300 kPa), this blowing method often fails to effectively remove fine particles adhering to the filter, especially stubborn dirt deeply embedded in the filter fibers, resulting in poor dust removal performance.

[0004] Besides the aforementioned equipment dependence and insufficient air pressure issues, the incompatibility between existing dust blowers and the brake main pipe interface is also a significant factor restricting dust removal efficiency. Due to the interface mismatch, operators must rely on complex adapters to achieve the connection, which not only increases the complexity of the operation but also potentially poses safety hazards due to the instability of the adapters. This incompatibility problem not only affects the efficiency of dust removal operations but also places higher demands on the operators' skills and patience.

[0005] In summary, the current air filter cleaning work for railway track maintenance vehicles faces multiple technical challenges, including long processing times, high material consumption, strong equipment dependence, insufficient air pressure, and interface incompatibility. To address these issues, the industry urgently needs to develop more efficient, convenient, and economical dust removal solutions to improve the overall maintenance efficiency and operational safety of railway track maintenance vehicles. Summary of the Invention

[0006] The purpose of this invention is to overcome the problems of existing dust removal equipment that uses an external high-pressure machine for dust removal, resulting in large space occupation and insufficient air pressure, and to provide a multi-functional dust removal gun suitable for rail work vehicles.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A multi-functional dust removal gun suitable for rail work vehicles includes a power source device, which is connected to the dust removal gun via a connecting pipe. The dust removal gun is positioned to align with the filter element. The power source device uses high-pressure air from the main air cylinder of the rail work vehicle, and the pressure of the high-pressure air is greater than 500 kPa.

[0009] A brake main pipe is provided between the power source device and the connecting pipe.

[0010] The brake main pipe is connected in sequence to the brake main pipe connector and the air duct connector.

[0011] The interface standards of the brake main connector and the air duct connector are consistent.

[0012] The interface between the brake main connector and the air duct connector is sealed with a rubber ring.

[0013] The duct connector has a through hole at its end, and a first quick connector is installed in the through hole. The first quick connector is connected to one end of the connecting pipe.

[0014] The other end of the connecting pipe is connected to the dust removal gun via a second quick connector.

[0015] The dust removal gun has a nozzle at the front end, and the diameter of the nozzle is adjustable.

[0016] The dust removal gun is equipped with a pressure regulating valve.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model provides a multi-functional dust removal gun suitable for rail work vehicles, including a power source device. The power source device is connected to the dust removal gun through a connecting pipe. The dust removal gun is positioned to be aligned with the filter element. It uses high-pressure air from the main air cylinder of the rail work vehicle as the power source, eliminating dependence on external air sources and realizing direct utilization of high-pressure air, thereby improving dust removal efficiency and convenience.

[0019] Furthermore, the quick-connect coupling enables rapid connection to the brake main pipe, significantly improving connection efficiency and ensuring that the airflow path can be quickly opened when needed and instantly opened and closed when not needed, thus greatly simplifying the overall workflow. This innovation not only optimizes the operating process but also enhances the system's flexibility and responsiveness, providing users with a more convenient and efficient user experience.

[0020] Furthermore, the power source device outputs a pressure of over 500 kPa, enhancing its ability to remove stubborn dust and dirt. Attached Figure Description

[0035] As shown in Figure 1, a multi-functional dust removal gun suitable for rail work vehicles includes a power source device 1. The power source device 1 uses high-pressure air from the main air cylinder of the rail work vehicle. The power source device 1 is connected in sequence to a brake main pipe 2, a brake main pipe connector 3, and an air duct connector 4. A through hole is opened at the bottom of the air duct connector 4. One end of a first quick connector 5 is inserted into the through hole, and the other end is connected to one end of a connecting pipe 6. The other end of the connecting pipe 6 is connected to a second quick connector 7. The second quick connector 7 is connected to a dust removal gun 8, and the dust removal gun 8 is aligned with the filter element 9.

[0036] Preferably, the first quick connector 5 and the second quick connector 7 include male and female connectors, the two ends of the connecting pipe 6 are male connectors, and the female connector of the first quick connector 5 is welded to the through hole to ensure the airtightness of the device.

[0037] Preferably, the brake main connector 3 and the air duct connector 4 have the same interface standard, and the interface is sealed with a rubber ring.

[0038] Preferably, the connecting pipe 6 is made of double-layer steel wire braid and is made of flexible hose material, so that the length can be adjusted according to the working needs.

[0039] Preferably, the dust removal gun 8 has an adjustable nozzle at the front end of its body, with a diameter of 3~5mm adjustable and a maximum airflow velocity of ≥200m / s.

[0040] Preferably, the dust removal gun 8 has a built-in pressure regulating valve (range 0~850kPa) to prevent overpressure from damaging the filter element.

[0041] Example 2

[0042] A multi-functional dust removal gun suitable for rail-mounted work vehicles, its working method is as follows:

[0043] Confirm that the power source device 1 has been started and the output high-pressure air pressure is greater than 500 kPa. Check that the interfaces of the brake main pipe 2, brake main pipe connector 3, and air duct connector 4 are free from deformation or corrosion and that the rubber sealing rings are intact.
