Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically a cleaning device suitable for use after coal trains are unloaded. Background Technology

[0002] When coal trains transport coal, coal dust is easily generated during loading and transportation due to the characteristics of coal itself. During transportation, coal dust can easily be dispersed into the air, causing air pollution. At the same time, it is prone to spontaneous combustion when the ambient temperature is high, posing a safety hazard. Therefore, it is necessary to clean coal trains.

[0003] A review of the publicly disclosed (announcement) number CN209650243U reveals an automatic coal mine train cleaning device. This technology discloses a technical solution that includes "a base, a brush bracket, a frame, a cylinder, a water spraying device, a chute, a motor, a brush nozzle, and a cylindrical brush. The frame is fixedly installed on two oppositely arranged bases, and brush brackets are welded to the two columns of the frame. This device has the technical effect of cleaning the surface of the train car when it passes slowly, with high cleaning efficiency, saving time and labor; and it can also uniformly spray water on the coal inside the car while cleaning the outer surface of the car car to prevent dust and spontaneous combustion during transportation."

[0004] While the above design allows for efficient and time-saving cleaning of the car body surface as the train passes slowly, the relatively fixed cleaning mechanism makes it difficult to clean the coal accumulation on the bottom and side walls of the car body. This results in insufficient and incomplete cleaning of coal dust inside the train car, reducing the effectiveness of the equipment in cleaning coal dust inside the train car. Therefore, we propose a cleaning device suitable for use after coal trains are unloaded to solve the above-mentioned problems. Utility Model Content

[0011] The other end of the rotary three-section robotic arm is fixedly mounted with a drive motor by bolts, and the output end of the drive motor is fixedly mounted with a cleaning brush by screws.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1 As shown:

[0026] A cleaning device suitable for cleaning coal trains after unloading includes two sets of support frames 1 and mounting holes 2 opened at the bottom of the support frames 1.

[0027] In this implementation plan: The existing device {Publication (Announcement) No.}: CN209650243U discloses an automatic coal mine train cleaning device. To solve the technical problems existing in this prior art, such as the background art disclosed above, "When the above design is used, although it can clean the surface of the car body when the train passes slowly, the cleaning efficiency is high and it saves time and labor, the cleaning mechanism is relatively fixed, and the coal accumulated on the bottom side wall of the car body is not easy to clean, so the cleaning of coal dust in the train car body is not comprehensive and thorough, reducing the cleaning effect of this device on the coal dust inside the train car body." In combination with the use, this problem is obviously a real and difficult problem to solve. Therefore, in order to solve this technical problem, a flexible cleaning component 3 is added to this application. All electrical equipment involved in this product is powered by an external power source.

[0028] Furthermore:

[0029] like Figures 1-3 As shown:

[0030] A flexible cleaning component 3 is installed between the two sets of support frames 1. The flexible cleaning component 3 includes a limiting guide rod 301 fixed between the two sets of support frames 1 and arranged symmetrically, a rack 303 disposed between the two sets of support frames 1, and a movable seat 304 sliding on the surface of the two sets of limiting guide rods 301. The movable seat 304 has a through hole for the rack 303 to pass through.

[0031] A stepper motor 306 is fixedly mounted on the surface of the movable base 304 by bolts. A spur gear 305 is fixedly mounted on the output end of the stepper motor 306 by screws. The spur gear 305 and the rack 303 are meshed together.

[0032] L-shaped plates 311 are fixedly installed on both sides of the movable seat 304 by bolts. A threaded rod 312 is rotatably connected between the two sets of L-shaped plates 311 by bearings. A stepper motor 307 for driving the threaded rod 312 to rotate is installed on the movable seat 304. A sliding seat 314 is threadedly connected to the surface of the threaded rod 312.

[0033] A three-section rotary robotic arm 315 with multi-directional angle adjustment is fixed to the lower surface of the sliding seat 314;

[0034] The other end of the rotary three-section robotic arm 315 is fixedly mounted with a drive motor 316 by bolts, and the output end of the drive motor 316 is fixedly mounted with a cleaning brush 317 by screws.

[0035] The surface of the movable base 304 is provided with a through hole that is adapted to the limiting guide rod 301, and the movable base 304 and the limiting guide rod 301 are slidably connected through this through hole;

[0036] A rotating rod 308 is fixedly installed at the output end of the stepper motor 307. A spur gear 309 is fixedly installed at the other end of the rotating rod 308 by screws. One end of the threaded rod 312 passes through the interior of the L-shaped plate 311 and extends to the exterior of the L-shaped plate 311. It is fixedly connected to the spur gear 310 located on the outside of the L-shaped plate 311 by screws. The spur gear 310 and the spur gear 309 are meshed together. A support block is fixed on the upper surface of a set of L-shaped plates 311 near the rotating rod 308. The support block and the rotating rod 308 are rotatably connected by bearings.

[0037] In this implementation plan: This cleaning device is applicable to coal trains after unloading. In use, the support frame 1 is first fixed to the railway track ground by bolts through the mounting holes 2 of the support frame 1. When the train moves the car frame between the two sets of support frames 1, the motor (not shown in the figure) at the joint of the rotary three-section robotic arm 315 is controlled by the automatic controller to drive a certain joint to adjust to a certain angle, so that the cleaning brush 317 on the drive motor 316 is in contact with the side wall of the train car. Then, the drive motor 316 is started to run, thereby driving the cleaning brush 317 to rotate. As the cleaning brush 317 rotates continuously, it cleans the coal dust on the side wall of the train car. Through the setting of the rotary three-section robotic arm 315, the cleaning brush 317 can be flexibly moved to any surface of the train car.

[0038] Simultaneously, stepper motor 306 is started to run, which drives spur gear 305 to rotate. Since spur gear 305 and rack 303 are meshed, while spur gear 305 is running, the moving seat 304 slides on the surface of the two sets of limit guide rods 301. Then, the moving seat 304 drives the rotary three-section robotic arm 315, drive motor 316 and cleaning brush 317 to move synchronously, thereby realizing the movement of the cleaning brush 317 in the X-axis direction.

[0039] By starting the stepper motor 307, the rotating rod 308 is driven to rotate, which in turn drives the spur gear 309 to rotate. Since the spur gear 309 and the spur gear 310 are meshed, the spur gear 310 is driven to rotate, which in turn drives the threaded rod 312 to rotate. Since the threaded rod 312 is threadedly connected to the sliding seat 314, the sliding seat 314 is driven to move. The sliding seat 314 drives the rotary three-section robotic arm 315, the drive motor 316, and the cleaning brush 317 to move synchronously, thereby realizing the movement of the cleaning brush 317 in the Y-axis direction.

[0040] This structure, through the setting of a rotating three-section robotic arm 315, can drive the cleaning brush 317 to fit against any surface of the inner wall of the train car. At the same time, it can realize the movement of the cleaning brush 317 in the X and Y directions relative to the plane, thus enabling flexible cleaning operations. This allows for a more comprehensive and thorough cleaning of coal dust inside the train car, improving the cleaning effect of this equipment on the coal dust inside the train car.

[0041] It should be noted that the rotary three-section robotic arm 315 consists of a rotary disk, three sets of segments, and a servo motor. The servo motor drives the angular rotation at the joints of every two sets of segments, while the rotary disk is equipped with a rotary motor, which in turn drives the three sets of segments to rotate flexibly.

[0042] The automatic control system uses an integrated microcontroller to automatically start the rotary three-section robotic arm 315, drive motor 316, stepper motor 306, and stepper motor 307. The operator can send operation commands through a remote transmitter. The remote receiver receives these commands and transmits them to the microcontroller. After receiving the commands, the microcontroller processes these signals through programming logic and outputs corresponding control signals to the drive module. The drive module then drives the corresponding motors to rotate according to the control signals, thereby achieving precise position control. This automatic control system can be set up according to existing technology, which will not be described in detail.

[0043] The rotary three-section robotic arm 315, drive motor 316, stepper motor 1 306 and stepper motor 2 307 are all powered by an external power source.

[0044] Furthermore;

[0045] In an optional embodiment, two sets of L-shaped plates 311 are fixed with symmetrically arranged limiting rods 313, and the sliding seat 314 slides on the surface of the two sets of limiting rods 313 through the opening limiting hole, so that the sliding seat 314 can be limited to move by the limiting rods 313.

[0046] In this embodiment, the sliding seat 314 slides on the surface of the two sets of limiting rods 313. By setting the limiting rods 313, the sliding seat 314 can be limited, making the sliding seat 314 more stable during movement.

[0047] Furthermore;

[0048] In an optional embodiment, a support plate 302 is fixed between the two sets of support frames 1, and a rack 303 is fixedly installed on the upper surface of the support plate 302, with the support plate 302 used to fix and support the rack 303.

[0049] In this embodiment, the support plate 302 can support the rack 303, which can effectively prevent the rack 303 from bending and affecting the meshing effect with the spur gear 305.

[0050] Furthermore;

[0051] In an optional embodiment, a protective cover 318 is fixedly mounted on the upper surface of the movable base 304 to protect the spur gear 305 and the stepper motor 307. The protective cover 318 and the rotating rod 308 are rotatably connected by bearings.

[0052] In this embodiment, the protective cover 318 provides better protection for the spur gear 305 and the stepper motor 307 during startup, thus extending their service life.

[0053] The working principle and usage process of this utility model: This cleaning device is applicable to coal trains after unloading. In use, the support frame 1 is first fixed to the railway track surface by bolts through the mounting holes 2. When the train moves the car body between the two sets of support frames 1, the automatic controller controls the motor (not shown in the figure) at the joint of the rotary three-section robotic arm 315, thereby driving a joint to adjust to a certain angle. This causes the cleaning brush 317 on the drive motor 316 to adhere to the side wall of the train car surface. Then, by starting the drive motor 316, the cleaning process is completed. The cleaning brush 317 is driven to rotate, and as it rotates, it cleans the coal dust from the side walls of the train car. The rotary three-section robotic arm 315 allows the cleaning brush 317 to move flexibly to any surface of the train car. Simultaneously, the stepper motor 306 is started, driving the spur gear 305 to rotate. Since the spur gear 305 meshes with the rack 303, the moving seat 304 slides on the surfaces of the two sets of limit guide rods 301 as the spur gear 305 rotates. Subsequently, the moving seat 304... The rotating three-section robotic arm 315, drive motor 316, and cleaning brush 317 move synchronously, thereby achieving movement of the cleaning brush 317 along the X-axis. Stepper motor 307 is activated, which in turn drives rotating rod 308 to rotate. Rotating rod 308 drives spur gear 309 to rotate. Since spur gear 309 and spur gear 310 are meshed, spur gear 310 is driven to rotate. Spur gear 310 drives threaded rod 312 to rotate. Since threaded rod 312 is threadedly connected to sliding seat 314, it drives sliding seat 314 to rotate. 4. Movement: The sliding seat 314 drives the rotary three-section robotic arm 315, drive motor 316, and cleaning brush 317 to move synchronously, thereby enabling the cleaning brush 317 to move in the Y-axis direction. This structure, through the setting of the rotary three-section robotic arm 315, can drive the cleaning brush 317 to fit against any surface of the inner wall of the train car, and at the same time enable the cleaning brush 317 to move in the X and Y directions relative to the plane, thus enabling flexible cleaning operations and more comprehensive and thorough cleaning of coal dust inside the train car, improving the cleaning effect of this equipment on the coal dust inside the train car.
