Description

Technical Field

[0001] This invention belongs to the field of high-speed train cleaning technology, and specifically relates to a high-speed train washing machine. Background Technology

[0002] The maintenance and repair work of high-speed trains includes cleaning the train bodies. Currently, due to the structure of the high-speed train maintenance depot, one side of the depot has a double-layered maintenance corridor for inspecting the train bodies and overhead tracks. The distance between the maintenance corridor and the train is often less than 100cm, so most existing car wash machines only clean one side; the side closer to the maintenance corridor can only be cleaned manually or by turning the train around, which is inefficient and cumbersome. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a high-speed train washing machine that can extend into the gap between the maintenance platform and the high-speed train to clean the outer wall of the train, thereby improving the cleaning efficiency of the high-speed train and simplifying its operation.

[0004] The present invention provides a high-speed train washing machine, comprising:

[0005] Water tank;

[0006] An automated guided vehicle is installed below the water tank to move the water tank.

[0007] A telescopic arm is installed on one side of the water tank, including a vertical support arm that extends up and down and a horizontal support arm that is connected to the vertical support arm and extends into the water tank.

[0008] Multiple rollers are respectively mounted on the vertical support arm and the horizontal support arm;

[0012] In an optional embodiment, a spray pipe assembly is mounted on the vertical support arm.

[0013] In an optional embodiment, the scrubbing cloth roller belt includes at least an outer layer and an inner layer. The outer layer is one of woven fabric, non-woven fabric, or a combination of woven fabric and non-woven fabric. The outer layer is fixed with a plurality of skirts perpendicular to the drive direction of the scrubbing cloth roller belt. The inner layer is a conveyor belt with synchronous teeth to engage with the roller.

[0014] In an optional embodiment, the lateral support arm extends laterally out of the water tank or retracts laterally into the water tank, wherein the lateral support arm extends laterally out of the water tank by a predetermined first distance so that the scrubbing cloth roller is in contact with the lower part of the train.

[0015] In an optional embodiment, the roller includes at least one guide roller, and at least one set of transverse support rods are fixed to the upper part of the first set of vertical support arms. The end of the transverse support rod near the vehicle extends out of the first set of vertical support arms by a predetermined second distance so that the wiping cloth roller is in contact with the upper part of the vehicle. At least one of the guide rollers is fixed between the transverse support rods.

[0016] In an optional embodiment, the roller further includes a limiting roller for limiting the wiping cloth roller belt, the limiting roller being fixed on the side of the vertical support arm away from the train.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0032] However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention. In the following detailed description, numerous specific details are set forth to provide a thorough understanding of embodiments of the invention for ease of explanation. However, it will be apparent that one or more embodiments may be practiced without these specific details. Furthermore, descriptions of well-known techniques are omitted in the following description to avoid unnecessarily obscuring the concepts of the invention.

[0033] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "comprising" as used herein indicates the presence of features, steps, or operations, but does not exclude the presence or addition of one or more other features.

[0034] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.

[0035] Reference Figure 1 and Figure 2 The present invention provides a high-speed train washing machine, comprising:

[0036] Water tank 8 is cubic in shape and hollow inside, so as to hold water for washing the scrubbing cloth roller 1;

[0037] The Automated Guided Vehicle (AGV) is installed below the water tank 8 to move the water tank 8. It includes the AGV chassis electrical control box 7 and the AGV chassis steering wheel assembly 9. The AGV chassis steering wheel assembly 9 includes steering wheels, drive wheels, rollers, a motor, a reducer, a steering mechanism, and a braking system. The motor outputs torque and transmits it to the drive wheels through the reducer, causing the drive wheels to move forward or backward. The steering wheels are mainly used for steering the front steering wheels. The steering mechanism controls the rotation angle of the steering wheels to change the turning radius and driving direction of the entire vehicle. The rollers are used to support the weight of the AGV and reduce friction between the drive wheels and the steering wheels. The braking system is used to achieve emergency stopping or parking fixation and can be controlled by electromagnetic force or hydraulic pressure.

[0038] The telescopic arm is installed on one side of the water tank 8, including a vertical support arm that extends up and down and a horizontal support arm connected to the vertical support arm and extending into the water tank 8; the vertical support arm can be extended and retracted by means of guide rail or folding; one end of the horizontal support arm extends into the water tank 8 to allow the scrubbing cloth roller 1 to enter the water tank 8 for cleaning.

[0039] Multiple rollers are respectively installed on the vertical support arm and the horizontal support arm 14, serving to support, drive, and limit the movement of the scrubbing cloth roller 1; some rollers are powered rollers with their own motors, generally located above the vertical support arm and the horizontal support arm 14; some rollers are driven rollers, with the powered rollers driving the scrubbing cloth roller 1 to rotate, thereby driving the driven rollers to rotate.

[0040] The wiping cloth roller 1 is installed on multiple rollers and extends into the water tank 8 along with the transverse support arm 14 for cleaning. Like the conveyor belt, it operates periodically under the drive of the rollers.

[0041] A drive unit that drives at least one drum to rotate can be installed inside the drum to drive the drum to rotate, or it can be installed on the water tank 8 and connected to the drum to drive the drum to rotate.

[0042] In a specific implementation, the water tank 8 may include a clean water tank and a wastewater tank, with the scrubbing cloth roller 1 installed in the wastewater tank; or the water tank 8 may include a clean water tank, a cleaning water tank, and a wastewater tank, with the scrubbing cloth roller 1 installed in the cleaning water tank. The clean water tank, the cleaning water tank, and the wastewater tank are controlled by a solenoid valve (which is connected to a control component), which automatically discharges water from the clean water tank into the cleaning water tank, automatically discharges water from the cleaning water tank into the wastewater tank, and automatically discharges wastewater from the wastewater tank into the water tank.

[0043] Furthermore, referring to Figure 3 The vertical support arm includes a first set of vertical support arms 2, a second set of vertical support arms 4, and a third set of vertical support arms 10 connected sequentially from high to low. The width of the first set of vertical support arms 2 is smaller than the width of the second set of vertical support arms 4 so that the first set of vertical support arms 2 can extend to the second set of vertical support arms 4. The width of the second set of vertical support arms 4 is smaller than the width of the third set of vertical support arms 10 so that the second set of vertical support arms 4 can extend to the third set of vertical support arms 10.

[0044] Here, as Figure 3 As shown, the first set of vertical support arms 2 has two arms, one on the left and one on the right, with a distance of 60cm between them. Similarly, the second set of vertical support arms 4 and the third set of vertical support arms 10 also have two arms, one on the left and one on the right. The distance between the two arms of the second set of vertical support arms 4 is 80cm, and the distance between the two arms of the third set of vertical support arms 10 is 100cm. The upper ends of the two arms of the third set of vertical support arms 10 are lower than the upper surface of the water tank 8. The width of the first set of vertical support arms 2 is less than the width of the second set of vertical support arms 4, and the width of the second set of vertical support arms 4 is less than the width of the third set of vertical support arms 10. This allows the three sets of support arms to retract or extend sequentially. When the vertical support arms are retracted, their height does not exceed the height of the maintenance platform (e.g., Figure 7 As shown, the second-floor platform is a maintenance platform, which facilitates movement under the maintenance platform.

[0045] Preferably, such as Figure 4 As shown, a spray pipe assembly 5 is installed on the vertical support arm. The spray pipe assembly 5 has two sets, upper and lower, each set with two nozzles. The nozzles spray water 13 to wash the cleaning agent carried to the surface of the train by the scrubbing cloth roller 1. The spray pipe assembly 5 also includes a connecting pipe and an electric valve. One end of the connecting pipe is connected to one set of nozzles, and the other end of the connecting pipe is connected to the clean water tank in the water tank. The electric valve is installed on the connecting pipe to realize the opening and closing of the connecting pipe. The electric valve can be a two-way ball valve, which is controlled by the control component.

[0046] Furthermore, the scrubbing cloth roller 1 includes at least an outer surface layer and an inner surface layer. The outer surface layer is one of woven fabric, non-woven fabric, or a combination of woven fabric and non-woven fabric. The outer surface layer is fixed with a plurality of skirts perpendicular to the transmission direction of the scrubbing cloth roller 1. The inner surface layer is a conveyor belt with synchronous teeth to engage with the roller.

[0047] Specifically, in this embodiment, the outer layer of the scrubbing cloth roller 1 is made of cotton cloth, with its skirt evenly fixed to the outer surface in a straight or wavy shape. The skirt extends perpendicularly to the direction of movement (axial direction) of the scrubbing cloth roller 1. Furthermore, the outer and inner layers are sewn together with abrasion-resistant thread. In this embodiment, the scrubbing cloth roller 1 can mimic the scrubbing effect of a rag, extending into the gap between the maintenance platform and the train under the drive of the vertical support arm to clean the outer wall of the train. The lower surface of the inner layer is the same as a regular conveyor belt, and the outer surface of this conveyor belt is provided with a full-face synchronous tooth. The synchronous tooth meshes with the roller, causing the roller to drive the conveyor belt, thereby allowing the skirted cotton cloth of the outer layer to scrub the outer surface of the train.

[0048] In alternative implementations, such as Figure 5 As shown, the lateral support arm 14 extends laterally out of the water tank 8 or retracts laterally into the water tank 8, wherein the lateral support arm 14 extends laterally out of the water tank 8 by a predetermined first distance so that the wiping cloth roller 1 fits against the lower part of the train.

[0049] Here, the internal support frame 11 is fixed inside the water tank 8, and multiple guide rollers 15 are installed on the internal support frame 11 to change the transmission direction of the cleaning cloth roller 1. The transverse support arm 14 is installed on the internal support frame 11 and is horizontally (i.e., laterally) extendable. The transverse support arm 14 extends out of the water tank 8 by a predetermined first distance so that the side of the cleaning cloth roller 1 closest to the vehicle is in contact with the vehicle, thereby achieving effective cleaning of the vehicle's outer surface. The transverse support arm 14 generally extends out of the water tank 8 at a fixed height and position; in one possible embodiment, the highest point of the transverse support arm 14 is 4200mm from the ground.

[0050] In alternative implementations, such as Figure 5 As shown, the roller includes at least one guide roller 15, and at least one set of transverse support rods 16 are fixed on the upper part of the first set of vertical support arms 2. The end of the transverse support rod 16 near the train extends out of the first set of vertical support arms 2 by a predetermined second distance so that the wiping cloth roller 1 fits against the upper part of the train. At least one of the guide rollers 15 is fixed between the transverse support rods 16.

[0051] Specifically, the transverse support rod 16 also includes two support rods. The left transverse support rod 16 is installed on the first set of vertical support arms 2 on the left, and the right transverse support rod 16 is installed on the first set of vertical support arms 2 on the right. The guide roller 15 is installed between the left transverse support rod 16 and the right transverse support rod 16. There are also two guide rollers 15, such as... Figure 5 As shown, the guide rollers are installed at the ends of the transverse support rod 16 closest to the train and at the ends furthest from the train. In this embodiment, the guide roller 15 is a powered roller, and the motor controlling the guide roller 15 is located at one end of the guide roller 15 along its axial direction.

[0052] Preferably, in one possible embodiment, an automatic rebound structure is installed inside the transverse support rod 16 or between the transverse support rod 16 and the first set of vertical support arms 2. This structure, also known as a gravity-tension automatic rebound structure, includes a torsion spring and a limiter. When the vertical support arm is in the retracted state, the transverse support rod 16 is in a vertically retracted state; when the vertical support arm extends to a certain height, the transverse support rod 16 is laterally opened and leveled under the action of the scrubbing cloth roller 1. Since the length of the scrubbing cloth roller 1 is constant, and as... Figure 5 As shown, both the transverse telescopic arm 14 and the transverse support rod 16 extend a certain distance towards the train, so the wiping cloth roller 1 has a certain arc. This arc can automatically conform to the curved shape of the train. When the wiping cloth roller 1 wipes the train counterclockwise, the transverse support rod 16 and the transverse telescopic arm 14 can also make the wiping cloth roller 1 have a certain tension and pressure, thereby ensuring adaptive wiping of the curved outer wall of the train and improving the cleaning effect.

[0053] In alternative implementations, such as Figure 5 As shown, the roller also includes a limiting roller 3 that limits the wiping cloth roller 1, and the limiting roller 8 is fixed on the side of the vertical support arm away from the train.

[0054] Here, the limiting roller 3 limits the wiping cloth roller 1 so that the wiping cloth roller 1 can smoothly enter the water tank 8 along the set direction. In addition, the limiting roller 3 also guides the wiping cloth roller 1 and controls the tension of the wiping cloth roller 1.

[0055] In some possible embodiments, such as Figure 9 As shown, a pair of rollers for adjusting the dryness and humidity of the scrubbing cloth roller 1 are also installed in the water tank 8. The scrubbing cloth roller 1 rotates counterclockwise. When the scrubbing cloth roller 1 exits the water tank 8 after being washed with water, the dryness and humidity adjusting roller 17 is installed at the corresponding water outlet position and clamps or squeezes the scrubbing cloth roller 1. The dryness and humidity of the squeezed scrubbing cloth roller 1 are controlled by the distance between these two rollers. This dryness and humidity adjusting roller 17 can be controlled by the control component 6.

[0056] Preferably, the water tank 8 is equipped with a cleaning agent spraying assembly and a pulsator rotating cleaning assembly.

[0057] The impeller-driven cleaning assembly cleans the wiping cloth roller 1, which enters the water tank 8. A cleaning agent spraying assembly, installed beside the wiping cloth roller 1 inside the water tank 8, sprays cleaning agent onto the portion of the wiping cloth roller 1 that has been cleaned in the water tank 8, thus allowing the wiping cloth roller 1 to carry the cleaning agent and clean the outer surface of the train. In one possible embodiment, the cleaning agent spraying assembly is installed above the water tank 8; that is, when the wiping cloth roller 1 is squeezed by the humidity-regulating roller 17, the cleaning agent spraying assembly sprays cleaning agent onto the wiping cloth roller 1, and the wiping cloth roller 1 carries this cleaning agent to clean the outer surface of the train.

[0058] The impeller rotating cleaning assembly is a set of rollers with bristles. The impeller rotating cleaning assembly can be installed at the bottom of the water tank. When the scrubbing cloth roller 1 rotates to the bottom of the water tank, the impeller rotating cleaning assembly at the bottom contacts the scrubbing cloth roller 1 above and scrubs the scrubbing cloth roller 1 to remove the stains on the surface of the scrubbing cloth roller 1.

[0059] In an optional embodiment, a control component 6 is installed on the water tank 8. The control component 6 is electrically connected to the automatic guide vehicle, the cleaning agent spraying component, the impeller rotating cleaning component, and the spray pipe assembly 5, respectively, so as to control the operation of the cleaning agent spraying component, the impeller rotating cleaning component, and the spray pipe assembly 5.

[0060] In this embodiment, the scrubbing cloth roller 1 can be extended using a narrow telescopic arm. A guide roller 15 and a transverse support arm 14 are provided above the telescopic arm, and a transverse support arm 14 is also provided on the transverse guide rail below the equipment. When both the upper and lower sections extend simultaneously, a cloth wall composed of the scrubbing cloth roller 1 is formed. Figure 8 As shown. This embodiment adopts an upper-middle-lower structure. The lower layer is the AGV trolley and equipment power system; the middle layer is the water tank 8 and the scrubbing cloth roller 1 system and the scrubbing cloth roller 1 circulation system; the upper layer is the telescopic arm and spray system. In one possible embodiment, the width of the lateral support arm 14 is 80mm.

[0061] In this embodiment, during use, the entire device is moved horizontally towards the direction of the train until the cleaning cloth roller 1 is completely in contact with the train surface. The cleaning cloth roller 1 then slides downwards from the train surface (similar to the movement of a treadmill belt). The water tank 8 in the abdomen removes dirt from the train surface through the rotating impeller of the water tank 8, which then rolls it out. After passing the area where the cleaning agent is sprayed, it rolls upwards, and the train surface is cleaned again from top to bottom in a continuous cycle. During this process, the humidity and rolling speed of the cleaning cloth roller 1 can be adjusted as needed. Figure 8As shown, this embodiment is equipped with a clean water spray system, which can rinse away excess cleaning solution during the scrubbing process. When not in use, or when passing through the maintenance platform, the telescopic arm can be retracted. Figure 6 As shown.

[0062] The application diagram of this embodiment is as follows: Figure 7 and Figure 8 As shown, the wiping cloth roller 1 in this embodiment can mimic the wiping effect of a rag. Through the narrow telescopic arm structure, it can be inserted into the gap between the maintenance platform and the train to clean the outer wall of the train. This embodiment is a fully automatic cleaning machine that can automatically avoid obstacles.
