Description

Technical Field

[0001] The present application relates to the technical field of rail vehicle maintenance equipment, and in particular to an underbody dust collecting device of an underbody purge system of a rail vehicle. Background Art

[0002] During long-term operation, rail transit trains are prone to adsorbing or attaching dust on the roadbed. The long-term accumulation of dirt will affect the operation of the undercarriage equipment and thus affect the safety of the train.

[0003] To address the problems of high labor intensity, low efficiency, and severe environmental pollution in the work area caused by manual cleaning operations, Chinese utility model patent CN221068017U discloses an intelligent cleaning and dust removal system for urban rail trains. This system provides a dust shield, two dust removal units, and two air curtain units on the vehicle-side cleaning and dust removal robot. The dust shield and air curtain units form a movable, relatively enclosed working area between the undercarriage cleaning robot and the vehicle-side cleaning and dust removal robot to prevent dust from escaping.

[0004] However, this solution has the following drawbacks:

[0005] First, the front and rear of the undercarriage purge system remain open, allowing dust to escape. Furthermore, the dust shield clearly does not fit neatly against the vehicle's body or the ground, and the air curtain units on both sides cannot prevent dust from escaping from above or below. Therefore, this solution's effectiveness in addressing workplace pollution needs further improvement.

[0006] Second, the dust removal unit is only installed on the vehicle side cleaning and dust removal robot. During the cleaning process, some of the falling dust will be deposited on the ground under the vehicle, causing ground environmental pollution. Utility Model Content

[0007] In view of this, the utility model provides an underbody dust collection device for a rail vehicle underbody cleaning system to solve the problem that the existing technology cannot prevent dust from overflowing from the front and rear, the pollution of the working environment needs to be further improved, and some of the fallen dust will be deposited on the ground under the vehicle, causing ground environmental pollution.

[0008] The utility model provides an undercarriage dust collecting device of an undercarriage purge system for a railway vehicle, comprising an undercarriage trolley chassis, an undercarriage air compressor device being provided in the middle of the undercarriage trolley chassis, and an undercarriage dust collecting box assembly being provided on both sides of the undercarriage air compressor device along the length direction of the undercarriage track. The undercarriage dust collecting box assembly comprises:

[0009] The undercar dust collection box body is internally divided into a mutually isolated equipment chamber, a dust removal chamber, and an air curtain chamber. The top surface of the undercar dust collection box body is provided with an undercar dust suction port and a strip air curtain port at intervals. The strip air curtain port is located outside the undercar dust suction port, the undercar dust suction port is communicated with the dust removal chamber, and the strip air curtain port is communicated with the air curtain chamber;

[0012] The undercar air compressor device comprises an undercar air compressor assembly and an undercar air storage tank. The undercar air compressor assembly generates high-pressure air when in operation and stores the air in the undercar air storage tank.

[0013] The undercarriage dust collecting device of the above-mentioned undercarriage cleaning system of the railway vehicle is characterized in that the interior of the undercarriage dust collecting box body is divided into an equipment chamber, a dust removal chamber and an air curtain chamber isolated from each other. The top surface of the undercarriage dust collecting box body is provided with an undercarriage dust suction port and a strip air curtain port at intervals. The undercarriage centrifugal fan is arranged in the equipment chamber, and its air inlet is connected with the dust removal chamber, and the air outlet is connected with the air curtain chamber. Two undercarriage air curtains can be formed in the front and rear directions of the undercarriage of the railway vehicle, forming two wind walls to prevent the dust falling to the undercarriage from escaping from the front and rear and polluting the working environment.

[0014] In addition, the centrifugal fan under the vehicle can generate negative pressure in the dust removal chamber, sucking the dust falling to the ground under the vehicle into the dust collecting box under the vehicle for filtration and collection, so as to prevent the dust falling to the bottom of the vehicle from being deposited on the ground and polluting the ground environment.

[0015] In the above technical solution, preferably, the air curtain chamber is located in the upper portion of the undercar dust box housing, and the equipment chamber and the dust removal chamber are arranged side by side in the lower portion of the undercar dust box housing. A strip-shaped air curtain opening is formed on the top wall of the air curtain chamber, located outside the undercar dust suction port. The air curtain chamber is connected to the air outlet of the undercar centrifugal fan via a duct. This implementation simplifies the internal design of the undercar dust box housing, rationally utilizes space, and has a compact structure.

[0016] In the above technical solution, preferably, an underbody backflush nozzle is provided above each underbody air filter cartridge, connected to the underbody air tank, for backflush cleaning the underbody air filter cartridge. This solution enables backflush cleaning of the underbody air filter cartridge, thereby improving filtration efficiency and service life.

[0017] In the above technical solution, a pull-out undercar dust collection drawer is provided below the dust removal chamber, and the pull-out undercar dust collection drawer is slidably mounted on the undercar dust collection box body. This solution allows for easy removal of accumulated dust and dirt through the pull-out undercar dust collection drawer.

[0018] In the above technical solution, preferably, the underbody air filter cartridge is provided in plurality.

[0019] In the above technical solution, preferably, a guide plate is further provided within the dust removal chamber, the guide plate being located below the undercar dust suction port, with the lower end of the guide plate tilted toward the equipment chamber. This guide plate can guide dust sucked in from the undercar dust suction port toward the undercar air filter cartridge, thereby improving filtration efficiency and preventing dust from accumulating in the corners of the dust removal chamber.

[0020] As can be seen from the above technical solution, the undercarriage dust collection device of the undercarriage purge system provided by the present invention solves the problem that the existing technology cannot prevent dust from overflowing from the front and rear, which leaves the working environment pollution in need of further improvement, and that some of the fallen dust will be deposited on the ground under the vehicle, causing ground environmental pollution. Compared with the existing technology, the present invention has the following beneficial effects:

[0021] The dust removal chamber draws dust that falls to the ground beneath the vehicle into the undercarriage air filter cartridge for filtration and collection, preventing it from settling on the ground and polluting the ground environment. Furthermore, the strip-shaped air curtain openings create two undercarriage air curtains in the front and rear directions of the rail vehicle's undercarriage, forming two wind walls to prevent dust from escaping from the front and rear and polluting the working environment.

Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0031] In order to more clearly explain and illustrate the technical solution and implementation of the present invention, several preferred specific embodiments for implementing the technical solution of the present invention are introduced below.

[0032] It should be noted that the directional words such as "inside, outside", "front, back" and "left, right" in this article are expressed based on the product usage status. Obviously, the use of the corresponding directional words does not constitute a limitation on the scope of protection of this scheme.

[0033] like Figure 1 As shown, the present invention provides an undercarriage dust collection device 600 for a rail vehicle undercarriage cleaning system, comprising an undercarriage trolley chassis 610, which is mounted on and movable along the undercarriage tracks of the rail vehicle undercarriage cleaning system. An undercarriage air compressor assembly 620 is installed in the middle of the undercarriage trolley chassis 610, and undercarriage dust collection box assemblies 630 are installed on both sides of the undercarriage air compressor assembly 620 along the length of the undercarriage tracks.

[0034] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown, the undercar dust box assembly 630 includes an undercar dust box body 631, the interior of the undercar dust box body 631 is divided into a mutually isolated equipment chamber 6301, a dust removal chamber 6302 and an air curtain chamber 6303. Figure 5Filled in various linear forms. The air curtain chamber 6303 is located above the undercar dust box housing 631, while the equipment chamber 6301 and the dust removal chamber 6302 are arranged side by side at the bottom of the undercar dust box housing 631. The top surface of the undercar dust box housing 631 is spaced apart by an undercar dust suction port 634 and a strip-shaped air curtain port 635. The strip-shaped air curtain port 635 is located outside the undercar dust suction port 634, away from the undercar air compressor device 620. The undercar dust suction port 634 communicates with the dust removal chamber 6302, while the strip-shaped air curtain port 635 communicates with the air curtain chamber 6303.

[0035] The dust removal chamber 6302 is provided with a bottom air filter cartridge 633, and a plurality of bottom air filter cartridges 633 can be provided. A pull-out bottom dust collection drawer 636 is provided below the dust removal chamber 6302, and the bottom dust collection drawer 636 is slidably arranged on the bottom dust collection box body 631.

[0036] An undercarriage centrifugal fan 632 is housed within the equipment chamber 6301, with its air inlet communicating with the dust removal chamber 6302 and its air outlet communicating with the air curtain chamber 6303. Operation of the undercarriage centrifugal fan 632 creates a negative pressure in the dust removal chamber 6302, drawing dust that falls to the floor beneath the vehicle into the undercarriage dust collection box 631. The dust is then filtered through the undercarriage air filter cartridge 633, where it adheres to the filter element.

[0037] See also Figure 1 As shown, two undercarriage dust collection box assemblies 630, located on either side of the undercarriage air compressor assembly 620, form two undercarriage air curtains in the front-to-rear direction of the rail vehicle's undercarriage, creating two wind walls. This prevents dust that falls under the undercarriage from escaping from the front and rear, potentially polluting the working environment. Simultaneously, two undercarriage dust suction ports 634, located within the air curtains, draw dust within this area into the dust removal chamber 6302 for filtration and collection, preventing dust that falls under the undercarriage from settling on the ground and polluting the ground environment.

[0038] like Figure 7 As shown, the undercarriage air compressor device 620 includes an undercarriage air compressor assembly 621 and an undercarriage air tank 622. The undercarriage air compressor assembly 621 generates high-pressure air, which is stored in the undercarriage air tank 622. Each undercarriage air filter cartridge 633 is provided with an undercarriage backflush nozzle 637 above it. The undercarriage backflush nozzle 637 is connected to the undercarriage air tank 622 and can use the high-pressure air stored in the undercarriage air tank 622 to backflush and clean the undercarriage air filter cartridge 633. The dust and dirt blown away by the backflush fall into the undercarriage dust collection drawer 636. When the dust and dirt in the undercarriage dust collection drawer 636 accumulates to a certain amount, the undercarriage dust collection drawer 636 can be pulled out and emptied.

[0039] See also Figure 3 、 Figure 5 、 Figure 6A guide plate 638 is also provided in the dust removal chamber 6302. The guide plate 638 is located below the dust suction port 634 under the vehicle, and its lower end is inclined toward the equipment chamber 6301. In this way, the dust sucked in from the dust suction port 634 under the vehicle can be guided to the air filter cartridge 633 under the vehicle, thereby improving the filtration efficiency and preventing the dust from being deposited in the corners of the dust removal chamber 6302.

[0040] Based on the description of the above specific embodiments, the undercarriage dust collecting device of the undercarriage cleaning system of a railway vehicle provided by the present invention has the following advantages compared with the prior art:

[0041] First, the undercarriage dust box assembly is set in the ditch below the rail vehicle. The dust removal chamber is equipped with an undercarriage centrifugal fan, which can generate negative pressure in the dust removal chamber, and suck the dust falling to the ground under the vehicle into the undercarriage dust box for filtration and collection, so as to prevent the dust falling to the bottom of the vehicle from being deposited on the ground and polluting the ground environment.

[0042] Second, an air curtain cavity is provided inside the dust collecting box body, which is connected to the air outlet of the centrifugal fan under the vehicle. A strip air curtain opening is provided on the top surface of the dust collecting box body, which can form two air curtains under the vehicle in the front and rear directions of the bottom of the rail vehicle, forming two wind walls to prevent the dust falling to the bottom of the vehicle from escaping from the front and rear and polluting the working environment.

[0043] Finally, it should be noted that the terms "comprise," "include," or any other variations thereof, as used herein, are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus comprising the element.

[0044] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone should be aware of the structural changes made under the inspiration of the present invention. Any structural changes with the same or similar technical solutions as the present invention fall within the scope of protection of the present invention.
