[0049] Train transportation boasts advantages such as high capacity, low cost, high efficiency, clean and environmentally friendly operation, and unrestricted weather conditions. It is widely used for transporting bulk materials, such as ore and coal. During bulk material transport, moisture and vibration can cause some materials to adhere firmly to the train cars. Even after unloading, some material remains trapped, often clinging to the floor or sides of the cars, resulting in uneven surfaces within the cars that are extremely difficult to clean.

[0050] In terms of cleaning methods, it usually requires manual work or cleaning equipment.

[0051] The manual cleaning method is not only inefficient and has a poor working environment, but is also unsafe and poses certain safety hazards.

[0052] The principle of the cleaning equipment is to lay moving tracks on both sides of the carriage, set a gantry trolley on the moving tracks, set a mobile trolley on the gantry trolley, the mobile trolley is provided with a lifting component, and a sweeper is provided at the bottom of the lifting component. The sweeper includes a flexible hose, a drive motor, a bottom cleaning brush and a side wall cleaning brush. The sweeper is lifted and lowered in and out of the carriage through the lifting component, and the gantry trolley walks on the moving track to achieve cleaning of the carriage and crossing the carriage.

[0053] In the related existing technologies, the mast height is fixed and cannot be adjusted, and needs to be disassembled into components for transportation and assembly, which easily causes inconvenience in transportation and long assembly time, resulting in increased assembly and transportation costs, high time and labor costs, inconvenience in transfer, and easy to be restricted when the site height is restricted. When the mast height is restricted, the lifting and lowering of the cleaning device is also restricted.

[0054] In this regard, the utility model provides a height-adjustable carriage cleaning device, which can solve many problems caused by the fixed height of the door frame.

[0055] Reference Figure 1 The utility model provides a height-adjustable cleaning device for a carriage 300 according to an embodiment of the present invention, comprising a gantry assembly 100 and a cleaning mechanism 200 mounted on the gantry assembly 100. The gantry assembly 100 can be raised and lowered to change the height of the entire device, and to adjust the vertical position of the cleaning mechanism 200. The cleaning mechanism 200 is rotatably connected to the gantry assembly 100, so that it can be flipped upward from the bottom of the gantry assembly 100. When it is necessary to clean the carriage 300, the cleaning mechanism 200 is flipped upward to leave space below the gantry assembly 100, and at the same time, the height of the gantry assembly 100 is adjusted to allow the carriage 300 to pass from below. After that, the gantry assembly 100 moves to the top of the carriage 300, and the cleaning mechanism 200 is rotated downward to enter the carriage 300, and can be moved along the length direction of the carriage 300 to perform the cleaning operation of the carriage 300.

[0056] The height-adjustable cleaning device for the carriage 300 of the present invention is provided with a gantry assembly 100 whose height can be raised and lowered. The cleaning mechanism 200 does not need to be equipped with a lifting structure and can enter and exit the carriage 300 by flipping it up and down, thereby completing the cleaning operation of the carriage 300. Therefore, the height-adjustable cleaning device for the carriage 300 of the present invention can use the lifting and adjustment of the gantry assembly 100 to change the total height of the entire device to meet the height requirements of transportation, without the need for disassembly and assembly, which can improve transportation efficiency, reduce costs, and facilitate transfer. In addition, when the site height is limited, the lifting and adjustment of the gantry assembly 100 can be used to flexibly adapt to the site, thereby increasing the scope of application.

[0057] Reference Figure 2 In some embodiments of the present invention, the door frame assembly 100 includes a left frame assembly 101, a right frame assembly 102 and a top frame assembly 103. The left frame assembly 101 and the right frame assembly 102 can both be raised and lowered. The top frame assembly 103 is connected between the upper ends of the left frame assembly 101 and the right frame assembly 102 and can be raised and lowered by raising and lowering the left frame assembly 101 and the right frame assembly 102. The cleaning mechanism 200 is mounted on the top frame assembly 103. It can be understood that the door frame assembly 100 in this embodiment uses the left frame assembly 101, the right frame assembly 102 and the top frame assembly 103 to form a door-like structure, allowing the carriage 300 to pass through from below. When the left frame assembly 101 and the right frame assembly 102 are raised and lowered, the height position of the top frame assembly 103 relative to the ground and the height position of the cleaning mechanism 200 relative to the ground can be changed to achieve overall height adjustment. The height of the cleaning mechanism 200 can match the internal height of the compartment 300, so that when the cleaning mechanism 200 is flipped downward, it can automatically enter the compartment 300 to clean the bottom surface, side walls, etc. of the compartment 300. It is understood that the lifting and lowering adjustment of the left frame assembly 101 and the right frame assembly 102 are preferably adjusted synchronously.

[0058] Reference Figure 2 In some embodiments of the present invention, the left frame assembly 101 and the right frame assembly 102 both include a base frame 1021 and two upright columns 1022, and the two upright columns 1022 are escalably mounted at the front and rear ends of the base. The top frame assembly 103 is provided with two crossbeams 1031, and the two crossbeams 1031 are respectively connected between the upper ends of the two upright columns 1022. At the same time, the top frame assembly 103 is provided with multiple longitudinal beams 1032 between the two crossbeams 1031 for reinforcement. The left frame assembly 101 and the right frame assembly 102 are also provided with a lifting cylinder 1023, the bottom of the lifting cylinder 1023 is hinged to the base frame 1021, and the upper end is hinged to a crossbeam 1031 to control the lifting of the top frame assembly 103. Because the lifting cylinder 1023 is connected to the top frame assembly 103, only one lifting cylinder 1023 can be provided, that is, the lifting cylinder 1023 can be provided on either the left frame assembly 101 or the right frame assembly 102. Alternatively, the lifting cylinder 1023 can be integrated with the columns 1022 and the bottom frame 1021, that is, hydraulic chambers and hydraulic oil circuits can be provided in the bottom frame 1021 corresponding to the columns 1022 to achieve lifting control, which will not be described in detail here.

[0059] Reference Figure 1 、 Figure 3 and Figure 4 In some embodiments of the present invention, the cleaning mechanism 200 includes a tilting mounting frame 201 and a tilting cylinder. The tilting mounting frame 201 is rotatably connected to the mast assembly 100, with its rotation center positioned horizontally, thereby enabling up-and-down flipping. The tilting cylinder is connected between the tilting mounting frame 201 and the mast assembly 100 and is used to drive the tilting mounting frame 201 to flip up and down relative to the mast assembly 100. It will be appreciated that during up-and-down flipping, the height position of the tilting mounting frame 201 changes, thereby enabling entry and exit from the vehicle compartment 300.

[0060] In some embodiments of the present invention, the flip mount 201 has at least a first state and a second state during the rotation process. In the first state, the flip mount 201 remains horizontal, and in the second state, the flip mount 201 flips upward. The flip angle of the flip mount 201 when rotating from the first state to the second state is greater than 90°. It can be understood that the first state is the position state of the cleaning mechanism 200 when it is in operation, at which time the flip mount 201 is horizontally located below the top frame assembly 103, and the second state is the position state of the cleaning mechanism 200 flipped upward, at which time the cleaning mechanism 200 exits the carriage 300. By setting the flip mount 201 to flip upward at an angle greater than 90°, this embodiment can lift the cleaning mechanism 200 as high as possible when exiting the carriage 300 to avoid interference.

[0061] Reference Figure 1 and Figure 4 In some embodiments of the present invention, the cleaning mechanism 200 further includes a cleaning frame 202, which is rotatably mounted on the flip mount 201, and the rotation center of the cleaning frame 202 is perpendicular to the rotation center of the flip mount 201. When the flip mount 201 is rotated to a horizontal position, the rotation center of the cleaning frame 202 is in a vertical state. Taking the flip mount 201 in the first state as an example, the cleaning frame 202 is mounted at the lower end of the flip mount 201 and is connected to the geometric center position of the flip mount 201. With the structural arrangement of this embodiment, the cleaning frame 202 can rotate relative to the flip mount 201 to perform a 180° reversal or a 90° rotation avoidance in the carriage 300, thereby facilitating the implementation of various cleaning sequences.

[0062] Reference Figure 4 In some embodiments of the present invention, a scraper assembly 2023 is provided on the cleaning frame 202. The scraper assembly 2023 is located at one end of the cleaning frame 202 away from the flip mount 201 and is movable along the width of the cleaning frame 202 to displace material along the width of the cleaning frame 202. For example, when the flip mount 201 is in the first state, the scraper assembly 2023 is located at the bottom of the cleaning frame 202. Since the compartment 300 has discharge openings on both sides, the scraper assembly 2023 can scrape material from the bottom surface of the compartment 300 through the discharge openings. In actual operation, the cleaning mechanism 200 can be first controlled to move from one end of the compartment 300 to the other, discharging material within the cleaning area of ​​the scraper assembly 2023 from one side of the compartment 300. The cleaning mechanism 200 can then be controlled to flip 180° and reverse direction, moving back to its original end to clean and discharge material from the other side of the compartment 300. The specific structural form of the scraper assembly 2023 can be set with reference to relevant existing technologies and will not be described in detail here.

[0063] Reference Figure 4 In some embodiments of the present invention, the cleaning frame 202 is provided with side brush assemblies. The side brush assemblies are located at the left and right ends of the cleaning frame 202 and extend along the height direction of the cleaning frame 202 to clean the side walls of the vehicle compartment 300. Specifically, the side brush assemblies include a front brush assembly 2021 and a rear brush assembly 2022, which are located at the front and rear ends of the cleaning frame, respectively. The front brush assembly 2021 extends vertically to a certain height and is used to clean the bottom surface and side walls of the vehicle compartment 300 simultaneously. The rear brush assembly 2022 is mainly used to clean the bottom surface of the vehicle compartment 300, ensuring a good cleaning effect on the corners on both sides of the vehicle compartment 300.

[0064] Furthermore, the front brush assembly 2021 and the rear brush assembly 2022 can be adjusted along the width direction of the cleaning frame to avoid interference when the cleaning mechanism 200 is flipped up and down to enter and exit the carriage 300, or to adjust to accommodate carriages 300 of different widths. The specific adjustment method can be adjustment by translation or by left and right swing.

[0065] Reference Figure 4 In some embodiments of the present invention, a bottom brush assembly 2024 is provided on the cleaning frame 202. The bottom brush assembly 2024 is located at the end of the cleaning frame 202 away from the tilt mounting frame 201 and is used to clean the bottom surface of the vehicle compartment 300. For example, when the tilt mounting frame 201 is in the first position, the bottom brush assembly 2024 is located at the bottom of the cleaning frame 202 to clean the bottom surface of the vehicle compartment 300. Specifically, the bottom brush assembly 2024 can be a cleaning roller structure. The bottom brush assembly 2024 and the scraper assembly 2023 are arranged in a front-to-rear arrangement to prevent interference.

[0066] Reference Figure 3 In some embodiments of the present invention, a top brush assembly 2011 is provided on the flip mount 201. The top brush assembly 2011 is used to clean the upper end of the side walls of the compartment 300. Specifically, the top brush assemblies 2011 are provided at the four top corners of the flip mount 201, and the top brush assembly 2011 is provided with an L-shaped brush structure. When the flip mount 201 is horizontal, the brush structure abuts the upper end surface and inner side wall of the upper end of the side wall of the compartment 300, cleaning the upper end of the compartment 300 as the door frame assembly 100 moves. In the vertical direction, the cleaning area of ​​the top brush assembly 2011 connects with or intersects with the cleaning area of ​​the front brush assembly 2021 to ensure that the side walls of the compartment 300 are completely cleaned and covered. It is understood that when the flip mount 201 is flipped upward, the top brush assembly 2011 will separate from the side walls of the compartment 300.

[0067] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention.
