Description

Technical Field

[0001] This application relates to the field of carriage cleaning technology, and in particular to a carriage cleaning device. Background Technology

[0002] Bulk materials such as coal are mainly transported by train or heavy truck. After transportation, residual material will adhere to the inner surface of the carriage, which needs to be cleaned by a carriage cleaning device. The carriage cleaning device is equipped with a horizontal brush unit and a vertical brush unit. The vertical brush unit extends vertically to clean the side walls of the carriage and the corners at the bottom of the side walls. The horizontal brush unit extends horizontally to clean the inner bottom surface of the carriage.

[0003] However, the width of different parts of the carriage may vary slightly, and due to structural fatigue, material impact or external pressure, the side walls and bottom may have local dents, twists and other deformations. In addition, the shape of the corners at the bottom of different types of carriages may vary, such as having triangular ribs or chamfers. As a result, the existing cleaning structure cannot be adapted to the different inner surfaces of the carriage, which can easily lead to gaps or excessive compression. The former will reduce the cleaning effect, while the latter will increase the running resistance or even damage the carriage. Summary of the Invention

[0004] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a carriage cleaning device in which the vertical brush unit is more adaptably fitted to the side wall and bottom corner of the carriage, and the horizontal brush unit is more adaptably fitted to the inner bottom surface of the carriage. This not only improves the cleaning effect, but also reduces running resistance, avoids damage to the carriage, and protects the carriage cleaning device itself.

[0005] According to an embodiment of this application, a vehicle cleaning device includes a mounting frame, two vertical brush assemblies, and a horizontal brush assembly. Each vertical brush assembly includes a slide, a hinged base, a vertical brush unit, a first elastic element, and a second elastic element. The two slides are slidably disposed on the mounting frame along a first direction and arranged along that direction. The hinged base is hinged to the slides about a vertical axis. The first elastic element is disposed between the hinged base and the slides. The vertical brush unit is movably disposed on the hinged base, and the second elastic element is disposed between the vertical brush unit and the hinged base.

The horizontal brush unit is movably disposed on the mounting frame, and the third elastic element is disposed between the horizontal brush unit and the mounting frame.

[0006] The carriage cleaning device according to the embodiments of this application has at least the following beneficial effects: In this application, when the carriage cleaning device enters the carriage and moves along the carriage, the side wall of the vertical brush unit cleans the inner side wall of the carriage, the bottom end of the vertical brush unit cleans the corner position at the bottom of the carriage, and the horizontal brush unit cleans the inner bottom surface of the carriage. Since the vertical brush unit is hinged to the slide seat through the hinge seat, and a first elastic member is provided between the hinge seat and the slide seat, the first elastic member can make the side wall of the vertical brush unit elastically abut against the side wall of the carriage.

[0022] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0023] The following is for reference. Figures 1 to 6 This application describes a carriage cleaning device according to an embodiment of the present application.

[0024] like Figures 1 to 6 As shown, the carriage cleaning device according to an embodiment of this application includes a mounting bracket 100, two vertical brush assemblies 200 and a horizontal brush assembly 300.

[0025] The mounting bracket 100 can be installed on the gantry assembly of the entire carriage cleaning equipment. The bottom of both sides of the gantry assembly is provided with traveling wheels. The ground on both sides of the carriage can be laid with tracks. The gantry assembly can be slidably installed on the tracks through the traveling wheels, thereby driving the carriage cleaning device to move along the length of the carriage. The gantry assembly can be provided with a lifting mechanism, a lateral movement mechanism and a rotating mechanism. The lifting mechanism drives the carriage cleaning device to lift and lower. The lateral movement mechanism drives the carriage cleaning device to move along the width of the carriage to facilitate the carriage cleaning device to enter and exit the carriage. The rotating mechanism drives the carriage cleaning device to rotate around the vertical axis to facilitate the carriage cleaning device to change the cleaning direction.

[0026] The vertical brush assembly 200 includes a slide 201, a hinge seat 202, a vertical brush unit 203, a first elastic element 204, and a second elastic element 205.

[0027] Two sliding blocks 201 are slidably mounted on the mounting frame 100 along a first direction and arranged in that direction. For example, when the cleaning device is located inside the carriage, the first direction can be the width direction of the carriage. The two sliding blocks 201 are slidably mounted on the mounting frame 100 along the width direction of the carriage and arranged in that direction. They can be driven by a hydraulic cylinder or a motor screw mechanism to slide synchronously in a direction that moves closer to or further away from each other. When the two sliding blocks 201 are located on both sides of the mounting frame 100 along the first direction, the two vertical brush units 203 clean the side walls of the carriage in the width direction. When the cleaning device moves to both ends of the carriage in the length direction, the two sliding blocks 201 can slide in a direction that moves closer to each other to drive the two vertical brush units 203 to clean the side walls of the carriage in the length direction. Of course, the first direction can also be other directions, which will not be elaborated here.

[0028] The hinge seat 202 is hinged to the slide 201 about a vertical axis, and the first elastic element 204 is disposed between the hinge seat 202 and the slide 201. For example, the top and bottom ends of the hinge seat 202 can be provided with rotating shafts, and are hinged to the slide 201 through the rotating shafts. The first elastic element 204 can be a compression spring or an elastic pressure plate, etc., and can extend in the horizontal direction. Since the hinge seat 202 can rotate about a vertical axis, the first elastic element 204 can apply a horizontal elastic force to the hinge seat 202, thereby enabling the side wall of the vertical brush unit 203 to elastically abut against the inner side wall of the carriage, thus enabling the side wall of the vertical brush unit 203 to float and fit against the inner side wall of the carriage.

[0029] The vertical brush unit 203 is movably mounted on the hinge seat 202, and the second elastic element 205 is disposed between the vertical brush unit 203 and the hinge seat 202. For example, the vertical brush unit 203 may be slidably mounted on the hinge seat 202, and two second elastic elements 205 of the same vertical brush assembly 200 may be provided and distributed vertically. The second elastic element 205 may be a compression spring or an elastic pressure plate, etc., and may extend vertically. Since the vertical brush unit 203 can move vertically, the second elastic element 205 can apply a vertical elastic force to the vertical brush unit 203, thereby enabling the bottom end of the vertical brush unit 203 to elastically abut against the corner position of the bottom of the carriage, thus enabling the bottom end of the vertical brush unit 203 to float and fit against the corner position of the bottom of the carriage.

[0030] The horizontal brush assembly 300 includes a horizontal brush unit 301 and a third elastic member 302. The horizontal brush unit 301 is movably mounted on the mounting frame 100, and the third elastic member 302 is disposed between the horizontal brush unit 301 and the mounting frame 100. For example, the horizontal brush unit 301 may be slidably mounted on the mounting frame 100, and the third elastic member 302 may be a compression spring or an elastic pressure plate, etc., and the third elastic member 302 may extend vertically. Because the horizontal brush unit 301 can move vertically, the third elastic member 302 can apply a vertical elastic force to the horizontal brush unit 301, thereby enabling the horizontal brush unit 301 to elastically abut against the inner bottom surface of the carriage, thus achieving a floating fit between the horizontal brush unit 301 and the inner bottom surface of the carriage.

[0031] In this application, when the carriage cleaning device enters the carriage and moves along the carriage, the side wall of the vertical brush unit 203 cleans the inner side wall of the carriage, the bottom end of the vertical brush unit 203 cleans the corner position at the bottom of the carriage, and the horizontal brush unit 301 cleans the inner bottom surface of the carriage. Since the vertical brush unit 203 is hinged to the slide 201 through the hinge seat 202, and a first elastic member 204 is provided between the hinge seat 202 and the slide 201, the first elastic member 204 enables the side wall of the vertical brush unit 203 to elastically abut against the side wall of the carriage. Since the vertical brush unit 203 is movably mounted on the hinge seat 202, and a second elastic member 205 is provided between the vertical brush unit 203 and the hinge seat 202, the second elastic member 205 can make the bottom end of the vertical brush unit 203 elastically abut against the corner position of the bottom end inside the carriage. Since the horizontal brush unit 301 is movably mounted on the mounting frame 100, and a third elastic member 302 is provided between the horizontal brush unit 301 and the mounting frame 100, the third elastic member 302 can make the bottom surface of the horizontal brush unit 301 elastically abut against the inner bottom surface of the carriage.

[0032] In this way, the sidewalls of the vertical brush unit 203 can float and adhere to the inner sidewalls of the carriage, the bottom of the vertical brush unit 203 can float and adhere to the corner of the bottom of the carriage, and the horizontal brush unit 301 can float and adhere to the inner bottom surface of the carriage. Even if there are slight differences in the width of different parts of the carriage, or if the sidewalls and bottom surfaces may have local dents, twists, or other deformations due to structural fatigue, material impact, or external pressure, or if the shape of the corner of the bottom of different types of carriages may be different, such as having triangular ribs or chamfers, the vertical brush unit 203 can still fit fitably against the inner surface of the carriage, especially the corner of the bottom of the carriage. The horizontal brush unit 301 can fit fitably against the inner bottom surface of the carriage, avoiding gaps or excessive compression. This not only improves the cleaning effect but also reduces running resistance, avoids damage to the carriage, and protects the carriage cleaning device itself.

[0033] refer to Figure 3As shown, in some embodiments of this application, the hinge seat 202 is provided with two sliding grooves 206, which are arranged vertically and extend. The vertical brush unit 203 is provided with two sliders 207, which are slidably installed in the two sliding grooves 206 respectively. Each of the two sliding grooves 206 is provided with a second elastic member 205 extending vertically. In the same hinge seat 202, the opposite ends of the two second elastic members 205 abut against the two sliders 207 respectively, and the adjacent ends of the two second elastic members 205 abut against the adjacent sides of the two sliding grooves 206 respectively.

[0034] In this embodiment, two second elastic elements 205 and two sliders 207 are symmetrically arranged. One of the second elastic elements 205 can provide a downward elastic force, and the other second elastic element 205 can provide an upward elastic force. In this way, the bottom end of the vertical brush unit 203 can better elastically abut against the corner of the bottom of the carriage. It is not only suitable for situations where the corner of the bottom of the carriage is concave, but also suitable for situations where the corner of the bottom of the carriage has triangular ribs or chamfers. The floating cleaning effect on the corner of the bottom of the carriage is better.

[0035] refer to Figure 3 As shown, in some embodiments of this application, the hinge seat 202 is provided with two guide grooves 208, which are respectively connected to two sliding grooves 206. The slider 207 is provided with a detachable limiting member 209, which passes through the guide groove 208. At least one side of the sliding groove 206 is provided through the limiting member 209. When the limiting member 209 is removed, the slider 207 can be moved out from one side of the sliding groove 206. For example, the limiting member 209 can be a bolt, which is threadedly connected to the slider 207. The outer end of the bolt passes through the guide groove 208 and is threadedly connected to a nut. The nut is located outside the guide groove 208 for locking and limiting. Of course, the limiting member 209 can also be snapped onto the slider 207.

[0036] In this embodiment, when the vertical brush unit 203 needs to be installed, the slider 207 is inserted into the slide groove 206 from one side, and then the limiting member 209 is installed. When the vertical brush unit 203 needs to be removed, the limiting member 209 is removed, and then the slider 207 is moved out from one side of the slide groove 206. The installation and removal of the vertical brush unit 203 are more convenient.

[0037] refer to Figures 1 to 3As shown, in some embodiments of this application, the vertical brush unit 203 includes a vertical brush frame 210, a side wall roller brush 211, and an oblique sweeping roller brush 212. The side wall roller brush 211 is rotatably mounted on the vertical brush frame 210 and extends vertically. The side wall roller brush 211 is used to clean the side wall of the carriage. The oblique sweeping roller brush 212 is swayably connected to the bottom end of the side wall roller brush 211 and is used to clean the corner position at the bottom end of the side wall of the carriage. For example, a hydraulic motor can be provided on the upright brush holder 210. The hydraulic motor is connected to the side wall roller brush 211 to drive the side wall roller brush 211 and the oblique sweeping roller brush 212 to rotate synchronously. The bristles of the side wall roller brush 211 can extend approximately along the radial direction of the side wall roller brush 211. The bristles of the side wall roller brush 211 are used to clean the side walls of the carriage. The bristles of the oblique sweeping roller brush 212 can extend downward along the radial direction of the oblique sweeping roller brush 212. The bristles of the oblique sweeping roller brush 212 are used to clean the corner positions at the bottom of the carriage.

[0038] In this embodiment, the vertical brush unit 203 includes a side wall roller brush 211 and an oblique sweeping roller brush 212, which have a clear division of cleaning functions and better cleaning effect. Moreover, the oblique sweeping roller brush 212 is oscillatingly connected to the bottom end of the side wall roller brush 211. In this way, the oblique sweeping roller brush 212 can swing at a certain angle relative to the side wall roller brush 211, which makes it more suitable for the corner positions at the bottom of the carriage, resulting in a better cleaning effect.

[0039] It should be noted that the horizontal brush unit 301 may also include a horizontal brush frame and a horizontal brush. The horizontal brush frame is movably mounted on the mounting frame 100, and the horizontal brush is mounted on the horizontal brush frame.

[0040] refer to Figure 1 , Figure 2 , Figures 4 to 6 As shown, in some embodiments of this application, the carriage cleaning device further includes a suction assembly 400, which includes a plurality of moving frames 401, a plurality of suction pipes 402 and a plurality of first driving members 403.

[0041] Multiple transfer frames 401 are mounted on the mounting frame 100 and arranged along a first direction. The transfer frames 401 can be moved and adjusted along the first direction. For example, the mounting frame 100 may be equipped with a guide rail that extends along the first direction, and the transfer frames 401 may be equipped with pulleys and slidably mounted on the guide rail via the pulleys. When the mounting frame 100 is located inside the carriage, the mounting frame 100 can extend along the width direction of the carriage. The first direction can be the width direction of the carriage, meaning that the multiple transfer frames 401 can be arranged along the width direction of the carriage and can be moved and adjusted along the width direction of the carriage. The feeding ends of multiple suction tubes 402 are respectively connected to the multiple transfer frames 401, and the discharging ends of the multiple suction tubes 402 can be connected to the same negative pressure mechanism or to multiple negative pressure mechanisms respectively. The negative pressure mechanism sucks away the cleaned residue through the suction tubes 402. When the suction tube 402 is used to absorb the residue on the inner bottom surface of the carriage, the bottom end of the suction tube 402 is the feeding end. The negative pressure mechanism can generate negative pressure using a negative pressure fan or vacuum pump to suck up residual material. Multiple first driving components 403 are used to drive multiple moving frames 401 to move. It should be noted that the number of moving frames 401, suction pipes 402, and first driving components 403 are the same and correspond one-to-one. Each of the moving frames 401, suction pipes 402, and first driving components 403 can be provided in two or more forms; for example, each of the moving frames 401, suction pipes 402, and first driving components 403 can be provided in two forms.

[0042] Ideally, the remaining material should be evenly distributed on the bottom of the truck bed after unloading. However, this is rare in reality. After unloading by a tipper, the remaining material often accumulates on one side. The working conditions after unloading by a grab bucket or screw unloader are more complex and variable.

[0043] To address the irregular and uneven distribution of residual material inside the vehicle compartment, this application employs a system where the feeding ends of multiple suction tubes 402 are individually driven by corresponding first driving components 403. Each feeding end of the multiple suction tubes 402 can independently plan its movement trajectory and execute alternating, synchronous, or complementary cleaning strategies. For example, in areas with relatively uniform residual material distribution, the feeding ends of nearby suction tubes 402 can be moved back and forth by the corresponding first driving component 403 for uniform adsorption. Conversely, in areas with a large accumulation of residual material, the feeding ends of nearby suction tubes 402 can be moved to the accumulation area and then stopped for concentrated adsorption. Thus, compared to the prior art method of driving all suction tubes 402 synchronously using a single driving mechanism, this application uses multiple first driving components 403 to drive the feeding ends of multiple suction tubes 402 individually, which is more adaptable to the complex and ever-changing internal environment of the vehicle compartment and effectively improves the cleaning effect and efficiency of residual material removal.

[0044] refer to Figures 4 to 6As shown, in some embodiments of this application, the feeding end of the straw 402 is oscillatingly connected to the transfer frame 401. The suction assembly 400 also includes a plurality of second driving members 404, which are respectively disposed on the plurality of transfer frames 401 to drive the feeding ends of the plurality of straws 402 to oscillate. For example, the oscillation axis of the feeding end of the straw 402 may extend in a horizontal direction.

[0045] Compared to the fixed orientation of the suction nozzle of the suction tube 402 in the prior art, in this embodiment, each suction tube 402 is individually equipped with a second driving member 404. The second driving member 404 can drive the feeding end of the corresponding suction tube 402 to swing independently, so that the suction nozzle of the suction tube 402 can actively adjust its orientation and always be aligned with the thicker part of the residual material. In this way, the problem of dispersed suction force and reduced efficiency caused by the poor orientation of the suction nozzle of the suction tube 402 in the prior art can be solved. This maximizes the utilization of the power of the negative pressure mechanism, resulting in a larger suction volume per unit time, a lower energy consumption ratio, and an effective improvement in cleaning speed. In addition, by independently swinging and moving the feeding end of the suction tube 402, the suction range of the suction tube 402 can be greatly increased, effectively reducing the occurrence of blind spots and the occurrence of material leakage, and improving the cleaning effect of residual material in the truck compartment. In addition, the feeding end of the suction tube 402 can swing, making it more suitable for situations where there are pits or protrusions on the inner bottom surface of the carriage. This not only improves the suction effect of residual material in the pits, but also avoids interference with the protrusions.

[0046] In this application, the independent movement and oscillation of the suction end of the suction tube 402 allows for better adaptation to the vertical brush unit 203 and the horizontal brush unit 301, resulting in better residual material adsorption. This reduces material scattering and secondary dust generation during the cleaning process, improves final cleanliness, and ensures no residue or contamination in the vehicle compartment, meeting the high hygiene standards required for subsequent transportation of different materials. Furthermore, the entire device can flexibly handle various residual material distribution states caused by different unloading methods, effectively eliminating cleaning blind spots and achieving effective adaptation to complex and changing operating scenarios.

[0047] refer to Figures 4 to 6 As shown, in some embodiments of this application, the suction assembly 400 further includes a plurality of angle encoders 405, which are respectively disposed on a plurality of shift frames 401 to detect the angle of the oscillation of the suction end of a plurality of suction tubes 402.

[0048] In this embodiment, each transfer frame 401 is equipped with an angle encoder 405. The angle encoder 405 can detect the swing angle of the suction end of multiple suction tubes 402. The angle encoder 405 converts the detected result into an electrical signal and sends it to the controller of the truck bed cleaning equipment in real time. The controller controls the second drive unit 404 to drive the suction end of the suction tube 402 to swing to the required angle according to the received electrical signal. In this way, the swing direction and swing angle of the suction tube 402 can be programmably controlled and predicted, thereby making the cleaning efficiency of the truck bed more efficient and the cleaning effect better.

[0049] It should be noted that the angle encoder 405 is a common type of encoder, and its working principle will not be elaborated here.

[0050] refer to Figures 4 to 6 As shown, in some embodiments of this application, the feeding end of the straw 402 is provided with a mounting shaft 406, which is rotatably mounted on the transfer frame 401. The second driving member 404 includes a telescopic part 407, a first connecting rod 408, and a second connecting rod 410. The telescopic part 407 is provided on the transfer frame 401. One end of the first connecting rod 408 is provided with a hinge shaft 409 between it and the telescopic part 407, and the other end is connected to the mounting shaft 406. When the telescopic part 407 extends or retracts, it drives the mounting shaft 406 to rotate through the first connecting rod 408. The second connecting rod 410 is sleeved on the hinge shaft 409. The second connecting rod 410 is provided with a transmission groove 411 extending radially along the hinge shaft 409. The angle encoder 405 is provided with an input shaft 412, which passes through the transmission groove 411. The input shaft 412 and the second connecting rod 410 are fixed relative to each other in the circumferential direction of the input shaft 412.

[0051] For example, the mounting shaft 406 can be located on opposite sides of the suction tube 402, and the mounting shaft 406 and the suction tube 402 are fixed relative to each other. The telescopic part 407 can be a hydraulic cylinder or an electric push rod, etc. The first connecting rod 408 and the mounting shaft 406 are fixed relative to each other along the circumference of the mounting shaft 406. The axis of the hinge shaft 409 between the telescopic part 407 and the first connecting rod 408 can be parallel to the axis of the mounting shaft 406. The second connecting rod 410 can extend radially along the hinge shaft 409. The axis of the input shaft 412 of the angle encoder 405 can be parallel to the axis of the mounting shaft 406. The outer diameter of the input shaft 412 itself can be larger than the width of the transmission groove 411. The outer peripheral wall of the input shaft 412 can be provided with a mating groove. The shaft segment of the input shaft 412 forming the mating groove passes through the transmission groove 411. The surface of the mating groove can fit against the surface of the transmission groove 411 to restrict the relative rotation of the input shaft 412 and the second connecting rod 410.

[0052] In this embodiment, when the telescopic part 407 is activated, the first connecting rod 408 drives the mounting shaft 406 to rotate by a certain angle during the telescopic process, thereby causing the suction end of the suction tube 402 to swing. This design is simple in structure, easy to operate, and provides a better effect in driving the suction end of the suction tube 402 to swing. Furthermore, when the telescopic part 407 drives the mounting shaft 406 to rotate via the first connecting rod 408, the second connecting rod 410 correspondingly drives the input shaft 412 of the angle encoder 405 to rotate. The angle encoder 405 can then obtain the rotation angle of the mounting shaft 406 in real time based on the rotation angle of the input shaft 412, thus obtaining the swing angle of the suction end of the suction tube 402. Through the linkage of the first connecting rod 408 and the second connecting rod 410, the angle encoder 405 can perform detection more conveniently and more accurately. In addition, the second link 410 is provided with a transmission groove 411 extending radially along the hinge shaft 409, and the input shaft 412 passes through the transmission groove 411. The input shaft 412 can slide relative to the second link 410, thereby avoiding interference between the second link 410 and the input shaft 412 of the angle encoder 405.

[0053] It should be noted that in some other embodiments of this application, the second driving member 404 can also be other structures, for example, it can be a hydraulic cylinder directly connected to the outer peripheral wall of the suction end of the suction pipe 402. In addition, the input shaft 412 of the angle encoder 405 can also be directly connected to the mounting shaft 406.

[0054] refer to Figure 5 and Figure 6 As shown, in some embodiments of this application, the centerline of the mounting shaft 406 extends along a second direction, which is perpendicular to the first direction.

[0055] When the mounting bracket 100 moves the suction tube 402 along the length of the carriage, the first direction is generally the width direction of the carriage. In this embodiment, the axis of the mounting shaft 406 extends along the second direction, which is perpendicular to the first direction. Thus, when the two outermost suction tubes 402 move to the two sides of the carriage width direction, the suction ends of the two outermost suction tubes 402 swing, making it easier for the suction nozzles of the two outermost suction tubes 402 to face the corner of the inner bottom surface and side wall of the carriage. This results in better cleaning of residual material at the corner and a cleaner cleaning. Moreover, it can effectively prevent interference between the suction ends of the suction tubes 402 and the reinforcing ribs or chamfers at the corner.

[0056] refer to Figures 4 to 6As shown, in some embodiments of this application, the mounting frame 100 is provided with a rack 101 extending along a first direction. The first driving member 403 includes a driving gear 415 and a driving part 416. The driving gear 415 is disposed on the transfer frame 401 and meshes with the rack 101. The driving part 416 is disposed on the transfer frame 401 and connected to the driving gear 415 to drive the driving gear 415 to rotate. The transfer frame 401 is provided with a detection gear 413 that meshes with the rack 101. The suction assembly 400 also includes multiple displacement encoders 414, which are respectively disposed on multiple transfer frames 401. On the same transfer frame 401, the displacement encoder 414 is connected to the detection gear 413 to detect the displacement of the transfer frame 401 according to the number of rotations of the detection gear 413. For example, the driving part 416 can be a hydraulic motor or a drive motor. The output end of the driving part 416 can be directly connected to the driving gear 415 or connected to the driving gear 415 through a reducer or the like.

[0057] When the drive unit 416 is activated, it drives the drive gear 415 to rotate. The drive gear 415, through meshing with the rack 101, pushes the transfer frame 401 to move along the first direction, thereby driving the suction end of the corresponding suction pipe 402 to move along the first direction. The structure is simple and easy to operate. Moreover, it can precisely control the displacement of the suction end of the suction pipe 402 by controlling the number of rotations of the drive gear 415 according to the actual distribution of residual material, thereby making the cleaning effect of residual material in the carriage better. Furthermore, the input end of the displacement encoder 414 can be coaxially connected to the detection gear 413, which meshes with the rack 101. Thus, when the shift frame 401 moves the suction end of the suction pipe 402 along the first direction, the detection gear 413 will rotate accordingly. The displacement encoder 414 can convert the number of rotations of the detection gear 413 into a corresponding pulse signal and send it to the controller. The controller can calculate the displacement of the shift frame 401 based on the number of received pulses, and thus obtain the displacement of the suction end of the suction pipe 402, thereby forming a closed-loop position control system. This achieves automated and precise positioning of the suction end of the suction pipe 402, effectively improving the cleaning effect and efficiency of the residual material in the carriage. In addition, both the drive gear 415 and the detection gear 413 mesh with the rack 101. Through the linkage between the drive gear 415 and the detection gear 413, the displacement encoder 414 can perform detection more conveniently and accurately.

[0058] It should be noted that in some other embodiments of this application, the transmission method of the first driving member 403 may also be a lead screw drive or other suitable transmission method, which will not be described in detail here. Furthermore, the displacement encoder 414 is a common type of encoder, and its working principle will not be described in detail here.

[0059] refer to Figure 4As shown, in some embodiments of this application, at least one of the sides of the mounting bracket 100 along the first direction that is close to the adjacent movable bracket 401 is provided with a limit switch 417, and at least one of the sides of two adjacent movable brackets 401 that are close to each other is provided with a limit switch 417. For example, the limit switch 417 may be provided at the end of the mounting bracket 100 along the first direction, or the limit switch 417 may be provided on one of the sides of two adjacent movable brackets 401 that are close to each other.

[0060] In this embodiment, a limit switch 417 is provided. When the outermost movable bracket 401 moves to the point of touching the end of the mounting bracket 100 along the first direction, or when two adjacent movable brackets 401 move to the point of touching each other, the limit switch 417 is triggered to generate an emergency stop signal. The emergency stop signal is sent to the controller, which controls the corresponding movable bracket 401 to stop moving, thus avoiding safety accidents and improving safety. It should be noted that the limit switch 417 can be a contact switch or an inductive switch, which will not be elaborated here.

[0061] refer to Figure 1 and Figure 4 As shown, in some embodiments of this application, the vehicle compartment cleaning device further includes two scrapers 500, which are respectively hinged to both sides of the mounting frame 100 along a first direction around a vertical axis. The scrapers 500 can rotate to an unfolded state abutting against the side wall of the vehicle compartment, and to a retracted state separated from the side wall of the vehicle compartment. A third driving member 501 is provided between the scraper 500 and the mounting frame 100, and the third driving member 501 is used to drive the scraper 500 to rotate. For example, the third driving member 501 can be a hydraulic cylinder or an electric push rod, etc.

[0062] In this embodiment, when the vertical brush unit 203 is working, the scraper 500 is driven to rotate to an unfolded state abutting against the side wall of the carriage by the third driving member 501. In this way, the scraper 500 can scrape off the residual material in the areas missed by the vertical brush unit 203, making the cleaning more thorough. After cleaning, when it is necessary to remove the carriage cleaning device of this application, or when it is necessary to rotate the carriage cleaning device to change the cleaning direction, the scraper 500 is driven to rotate to a retracted state separated from the side wall of the carriage by the third driving member 501. This avoids interference between the scraper 500 and the side wall of the carriage when removing the carriage cleaning device of this application or rotating the carriage cleaning device, making it more convenient to use.

[0063] In some embodiments of this application, a fourth elastic element may be provided between the scraper 500 and the mounting bracket 100, and the vertical brush unit 203 may be provided with a pushing part. When the two slides 201 slide in a direction away from each other, the pushing part pushes the scraper 500 to rotate to the unfolded state. When the two slides 201 slide in a direction away from each other to the point where the two vertical brush units 203 are in the working state of cleaning the side wall in the width direction of the carriage, the pushing part on the vertical brush unit 203, such as the pushing part on the vertical brush frame 210, can also push the scraper 500 to rotate to the unfolded state to facilitate the scraping of residual material. When cleaning is completed or the carriage cleaning device needs to be rotated, the two slides 201 move in a direction closer to each other to avoid interference between the vertical brush unit 203 and the side wall of the carriage. In this case, the scraper 500 rotates to the retracted state under the elastic restoring force of the fourth elastic element to avoid interference between the scraper 500 and the side wall of the carriage, making it more convenient to use.

[0064] In some embodiments of this application, the first elastic element 204, the second elastic element 205, and the third elastic element 302 are all configured as compression springs. All three elastic elements are in a compressed state, and their minimum compression relative to their natural state is adjustable. When the hinge seat 202 rotates at different angles, the degree of compression of the first elastic element 204 relative to its natural state varies. When the vertical brush unit 203 moves up and down to different positions, the degree of compression of the second elastic element 205 relative to its natural state varies. When the horizontal brush unit 301 moves up and down to different positions, the degree of compression of the third elastic element 302 relative to its natural state varies. The minimum compression mentioned in this embodiment refers to the minimum deformation of the first elastic element 204, the second elastic element 205, and the third elastic element 302 relative to their natural state when they undergo elastic compression. When the first elastic element 204, the second elastic element 205, and the third elastic element 302 are in the state of minimum compression, the pressure applied to the side wall and bottom of the vertical brush unit 203 and the bottom of the horizontal brush unit 301 is minimal, respectively.

[0065] In this embodiment, the first elastic element 204, the second elastic element 205, and the third elastic element 302 are all in a compressed state, and their minimum compression relative to their natural state is adjustable. This allows for adjustment of the minimum pressure applied by the first elastic element 204, the second elastic element 205, and the third elastic element 302 to the side wall and bottom end of the vertical brush unit 203, and the bottom end of the horizontal brush unit 301, respectively. For example, when the material inside the carriage is compacted, the pressure applied by the first elastic element 204, the second elastic element 205, and the third elastic element 302 relative to their natural state can be increased. The minimum compression amount in its natural state can increase the minimum pressure applied to the side wall and bottom of the upright brush unit 203 and the bottom of the horizontal brush unit 301, thereby increasing the cleaning effect. When the material in the carriage is in powder form, the minimum compression amount of the first elastic member 204, the second elastic member 205 and the third elastic member 302 relative to their natural state can be reduced, thereby reducing the minimum pressure applied to the side wall and bottom of the upright brush unit 203 and the bottom of the horizontal brush unit 301, avoiding excessive pressure that could damage the carriage, and reducing dust.

[0066] It should be noted that the first elastic element 204, the second elastic element 205, and the third elastic element 302 can be adjusted in various ways relative to their minimum compression in their natural state. Taking the first elastic element 204 as an example, for instance, referring to... Figure 3 As shown, the slide 201 may have a first connecting portion 213, and the hinge seat 202 may have a second connecting portion 214. The second connecting portion 214 may be hinged to a guide rod 215. The first connecting portion 213 may have a through hole, through which the guide rod 215 passes. A first elastic member 204 is sleeved on the guide rod 215 and located between the first connecting portion 213 and the second connecting portion 214. The guide rod 215 may have multiple limiting holes, which may be arranged along the length of the guide rod 215. The guide rod 215 extends out of the first connecting portion 213 at different positions on the side opposite to the second connecting portion 214, and limiting pins are inserted into different limiting holes, so that the limiting pins abut against the side of the first connecting portion 213 opposite to the second connecting portion 214. Alternatively, different numbers of washers may be sleeved on the guide rod 215, with the washers located between one end of the first elastic member 204 and the first connecting portion 213. Similarly, the adjustment method for the minimum compression of the second elastic element 205 and the third elastic element 302 can refer to that of the first elastic element 204.

[0067] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
