Description

Technical Field

[0001] The invention belongs to the technical field of residual coal cleaning, and in particular relates to a dry and wet coal cleaning operation unit. Background Art

[0002] In the modern train freight industry, in order to reduce the labor intensity of manual cleaning and improve cleaning efficiency and safety and environmental protection performance, the intelligent cleaning system of train cargo compartments has been widely used. The existing intelligent cleaning system of train cargo compartments mainly uses cleaning devices such as sweeping brushes and roller brushes to gather the residual coal on the inner wall and bottom of the compartment, and then guide the residual coal to the storage bin through the guide plate. However, this method mainly relies on gravity or simple conveying devices for material transmission, which has some significant shortcomings.

[0003] First, the existing system lacks an active conveying and unloading mechanism, resulting in low efficiency in the transmission of residual coal. Since the system mainly relies on gravity for transmission, the residual coal is easily dispersed during the transmission process, and some residual coal may even adhere to the cleaning equipment or guide plates, making it difficult to smoothly enter the storage bin. This passive transmission method greatly limits the overall efficiency of the cleaning system.

[0004] Secondly, during the unloading process, the existing system lacks auxiliary equipment such as a tipping bucket, which may cause the material transmission process to be affected by shaking and unstable factors, resulting in incomplete coal slag transmission. In this case, it will not only increase the necessity of manual intervention and reduce the degree of automation of the system, but also may cause coal slag residue and material loss.

[0005] In addition, the material transmission and unloading process during the cleaning process is not smooth enough, which can easily cause environmental pollution. For example, if the coal slag is not completely introduced into the storage bin during the transmission process, it may cause pollution inside or around the carriage, increasing the difficulty of cleaning and the cost of environmental governance.

[0006] In general, the existing intelligent cleaning system for train cargo compartments has problems such as low efficiency, large material losses, and easy environmental pollution in the transmission and processing of residual coal. It is urgent to improve the cleaning effect by improving the active transportation and unloading mechanism, and reduce manual participation and environmental impact. Summary of the invention

[0007] In view of the defects of the prior art, the present invention proposes a dry and wet coal sweeping operation unit. The dry and wet coal sweeping assembly utilizes the flexible movement and precise slide of the gantry to realize automatic cleaning and flipping unloading, thereby improving operation efficiency, ensuring equipment stability, reducing coal dust pollution, and significantly reducing the need for manual operation.

[0008] To achieve the above-mentioned purpose, the present invention provides a dry and wet coal sweeping operation unit, including a dry and wet coal sweeping assembly, a tipping bucket mechanism and a gantry assembly; the tipping bucket mechanism and the gantry assembly include a tipping bucket mechanism and a gantry, wherein the gantry is set on both sides of the coal car compartment, the dry and wet coal sweeping assembly is arranged on the top of the gantry and is located above the coal car compartment, and the tipping bucket mechanism is arranged on one side of the gantry; the dry and wet coal sweeping assembly can slide toward or away from the tipping bucket mechanism along the top slide of the gantry; a feeding port is provided at the top of the tipping bucket mechanism, and a discharging port is provided at the bottom of the dry and wet coal sweeping assembly; when the dry and wet coal sweeping assembly slides to the specified position of the tipping bucket mechanism, the discharging port of the dry and wet coal sweeping assembly is connected with the feeding port of the tipping bucket mechanism; the tipping bucket mechanism is used to receive the coal slag in the dry and wet coal sweeping assembly, and flip the collected coal slag into a collection container.

[0016] Optionally, the gantry includes a gantry body, a driving wheel arranged at the bottom of the gantry body, and a driving mechanism for driving the pulley to move.

[0017] By adopting the above technical solution, a driving wheel is installed at the bottom of the gantry body, and the movement of the driving wheel and the driving pulley is controlled by the driving mechanism, so that the gantry can move freely on the track or the specified path. This design gives the gantry efficient mobility, can quickly adapt to changes in the work site, and improves the flexibility of the operation.

[0018] Optionally, the driving mechanism includes a reduction gearbox and a motor; the motor is connected to an input shaft of the reduction gearbox via an output shaft, and the output shaft of the reduction gearbox is connected to a driving wheel via a coupling.

[0019] By adopting the above technical solution, the driving mechanism adopts a design in which the motor is connected to the input shaft of the reduction gearbox through the output shaft. Through the gear transmission of the reduction gearbox, the high-speed output of the motor is converted into a larger torque output, and the driving wheel can obtain a stronger driving force, thereby improving the overall driving efficiency of the gantry.

[0020] Optionally, a slideway is provided on each side of the top of the gantry body, and the slideway is used for sliding of the dry and wet coal sweeping assembly, and the sliding direction of the slideway is aligned with the tipping bucket mechanism on the side of the gantry.

[0021] By adopting the above technical solution, the slideways on both sides of the top of the gantry body are aligned with the tipping mechanism, ensuring that the dry and wet coal sweeping assembly can accurately dock with the feed port of the tipping mechanism during the sliding process. This design reduces the position error during the docking process and improves the overall efficiency of dry and wet coal sweeping and unloading operations.

Through the combination of multiple cleaning and collection methods, it achieves comprehensive coverage of different types of coal slag in different locations in the compartment, improving the cleaning efficiency.

[0024] Optionally, the flexible coal shoveling mechanism includes a coal storage box and a flexible bucket lifting assembly located on the inner side of the front end of the coal storage box, the coal storage box is provided with a negative pressure area, a normal pressure area and a lifting assembly accommodating cavity, and the flexible bucket lifting assembly is used to transport the scooped dry and wet residual coal into the normal pressure area of ​​the coal storage box.

[0025] By adopting the above technical solution, the flexible bucket lifting assembly can adapt to coal slag of different shapes and hardness, avoiding the problem of equipment wear caused by hard coal blocks, and flexibly shoveling the dry and wet residual coal in the coal car compartment, lifting it and transporting it to the normal pressure area of ​​the coal storage box, realizing the continuous operation process from shoveling to collection, improving the efficiency of coal shoveling and transportation, and ensuring the continuity and efficiency of the operation process. The coal storage box is equipped with a negative pressure area, a normal pressure area and a lifting assembly accommodating cavity.

[0027] By adopting the above technical solution, the vertical sweeping brush mechanism is arranged at the front end of the flexible coal shoveling mechanism, which can pre-clean the surface of the carriage before shoveling coal, effectively remove coal dust and small particles of coal slag, provide a cleaner working surface for subsequent coal shoveling operations, and improve the overall cleaning effect and efficiency. The negative suction and gravity sedimentation mechanism is arranged at the bottom and upper part of the coal storage box, which can generate negative pressure during the coal slag transportation process, adsorb and settle the coal dust in the air to the bottom of the coal storage box, effectively control the dispersion of coal dust generated during the cleaning process, reduce pollution to the working environment, and protect the health of operators. The gravity sedimentation mechanism uses gravity to settle heavier coal dust particles to the bottom of the coal storage box, while the negative suction action adsorbs and concentrates light coal dust in the negative pressure area. This dual collection method ensures efficient capture and sedimentation of coal dust, reduces the spillage of coal dust, and improves the dust removal effect of the entire system. The filtering and dust removal mechanism is installed above the negative pressure area of ​​the coal storage box, which can further filter and purify the coal dust sucked in the negative pressure area to ensure that the discharged air is clean and dust-free. This mechanism not only improves the dust removal ability of the equipment, but also plays a positive role in protecting the external environment and improving the air quality in the working area.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0048] As the instruction manual Figure 1-2The present invention records a dry and wet coal sweeping operation unit, comprising a dry and wet coal sweeping assembly 1 and a tipping bucket mechanism and a gantry assembly 2, wherein the tipping bucket mechanism and the gantry assembly 2 comprise a tipping bucket mechanism 20 and a gantry 21, wherein the gantry 21 is erected on both sides of the coal car compartment, the dry and wet coal sweeping assembly 1 is arranged on the top of the gantry 21 and is located above the coal car compartment, the tipping bucket mechanism 20 is arranged on one side of the gantry 21, the dry and wet coal sweeping assembly 1 can slide toward or away from the tipping bucket mechanism 20 along the top slide of the gantry 21, a feeding port is arranged on the top of the tipping bucket mechanism 20, and a discharging port is arranged at the bottom of the dry and wet coal sweeping assembly 1, when the dry and wet coal sweeping assembly 1 slides to the specified position of the tipping bucket mechanism 20, the discharging port of the dry and wet coal sweeping assembly 1 is docked with the feeding port of the tipping bucket mechanism 20, and the tipping bucket mechanism 20 is used to receive the coal slag in the dry and wet coal sweeping assembly 1, and flip the collected coal slag into a collection container. A driving mechanism is provided at the bottom of the gantry 21 so that the entire dry and wet coal sweeping operation unit can move along the length direction of the coal transport carriage.

[0049] Example 1

[0050] As the instruction manual Figure 3 The tipping mechanism 20 includes a tipping box 200, a telescopic rod 201, a connecting rod 202 and a discharge door 203. A mounting platform for the tipping mechanism 20 is provided on one side of the gantry 21. The tipping box 200 is the core component of the tipping mechanism, and its structure is a rectangular container. One side and the top of the tipping box 200 are set as openings. The top opening is a feed port, and the side opening is a discharge port. The discharge door 203 is arranged at the discharge port, and the feed port is connected to the discharge port of the dry and wet coal sweeping assembly 1. When the dry and wet coal sweeping assembly 1 is unloading, the coal ash falls directly into the tipping box 200 through the discharge port of the dry and wet coal sweeping assembly 1. The upper and lower edges of both sides of the tipping box 200 are symmetrically provided with support ears, which are used to connect the telescopic rod 201 and the gantry 21 to realize the flipping and positioning of the tipping bucket.

[0051] It should be noted that the discharge port of the dump box 200 is located at the front end of the dump box 200 .

[0052] The telescopic rod 201 adopts a hydraulic or pneumatic structure, and is used to provide turning power for the dump box 200. There are two telescopic rods 201, and the two telescopic rods 201 are respectively arranged on both sides of the dump box 200. The push rods of the telescopic rods 201 are connected to the upper edge ears on both sides of the dump box 200. The shell of the telescopic rod 201 is connected to the gantry 21, and is used to push or pull the rear end of the dump box 200 to be lifted or lowered through the piston movement of the push rod, thereby realizing the tilting or resetting of the dump box. The lower edge ears on both sides of the dump box 200 are hingedly connected to the gantry 21 to provide stable support and rotation axis points.

[0053] The discharge door 203 is arranged at the discharge port at the front end of the dump box 200, and is a rotatable door panel used to control the discharge of materials. The discharge door 203 is connected to the front edge of the dump box 200 by a hinge, and a bracket is extended from each of the top two sides of the discharge door 203 along the rear end direction of the dump box 200. There are two connecting rods 202 for stabilizing the rotation angle of the discharge door. One end of each connecting rod 202 is hingedly connected to the bracket on one side of the discharge door 203, and the other end is hingedly connected to the bottom of the same side of the dump box 200, so as to open or close the door panel when the dump is tilted, so as to realize the controllable discharge of materials.

[0054] Instructions attached Figure 1 The figure shows the closed state of the discharge door 203 of the dump mechanism 20. Figure 2 The figure shows the open state of the discharge door 203 of the bucket mechanism 20. When the bucket box 200 is in a horizontal position, the dry and wet coal sweeping assembly 1 discharges the coal ash into the bucket box after completing the cleaning task. After starting the bucket mechanism 20, the push rod of the telescopic rod 201 extends to push the rear end of the bucket box to lift up, forming an inclined angle. As the rear end of the bucket box 200 is lifted, the discharge door 203 at the front end of the box starts to move. The opening process of the discharge door 203 is determined by the hinge connection and the fixed length of the connecting rod 202. When the bucket box 200 is tilted, the fixed length of the connecting rod 202 and the position of the hinge point make the discharge door 203 rotate smoothly. The discharge door 203 automatically rotates downward due to gravity to open, thereby opening the discharge port and realizing the natural discharge of materials without the need for an additional drive device. After the discharge is completed, the telescopic rod 201 retracts, and the push rod pulls the rear end of the bucket box 200 to fall and return to the horizontal position. During this process, the discharge door 203 is automatically closed due to the effect of gravity and the limitation of the hinge point, ensuring that the dump box is completely sealed when resetting to prevent residual materials from leaking. After the dump box 200 is reset, the dry and wet coal sweeping assembly 1 can restart the next round of cleaning operations and continue to transport coal ash into the dump box.

[0055] Through the cooperation of the dry and wet coal sweeping assembly 1 and the tipping mechanism 20, a continuous process of automatic collection, transmission and unloading of coal ash is realized. The unloading door 203 in the tipping mechanism 20 uses its own gravity and hinged structure to realize automatic rotation opening and closing, which simplifies the mechanical design and improves the reliability and working efficiency of the device. While realizing efficient coal ash treatment, the device reduces the dependence on complex control systems and is suitable for various applications requiring efficient cleaning and treatment of coal ash.

[0056] Example 2

[0057] As the instruction manual Figure 4 This embodiment includes all the structures of embodiment 1, and the gantry 21 includes a gantry body, a driving wheel 210 arranged at the bottom of the gantry body, and a driving mechanism for driving the pulley to move.

[0058] The main body of the gantry adopts a rectangular frame structure, which is composed of vertical pillars and horizontal beams to ensure the stability and solidity of the entire frame. High-strength connections such as welding or bolting are used between the pillars and beams to improve the overall rigidity and load-bearing capacity. The frame material is steel or aluminum alloy, which not only has high strength and durability, but also can effectively resist deformation and vibration under load conditions to ensure sufficient strength and durability to withstand the weight of the dry and wet coal sweeping assembly 1 and its dynamic load when sliding. According to specific needs, surface coatings (such as anti-rust paint or anodizing treatment) can be selected to enhance corrosion resistance.

[0059] The bottom of the gantry is equipped with four driving wheels 210, which are installed at the four corners of the frame. Each driving wheel is made of highly wear-resistant material and has an anti-skid texture to ensure smooth operation on the ground rail. The driving wheels 210 move along the ground rails on both sides of the coal car carriage to ensure that the gantry 21 can slide linearly along the length of the carriage.

[0060] A slideway is provided on each side of the top of the gantry body for sliding of the dry and wet coal sweeping assembly 1. The slideway is a track made of wear-resistant material, such as steel or aluminum alloy, and the track surface is treated to reduce friction and wear. The cross-sectional shape of the slideway is designed to be U-shaped or V-shaped to adapt to the operation of the pulley. The shape of the track can effectively guide the movement direction of the pulley and provide lateral support to prevent the pulley from falling off the track.

[0061] The sliding direction of the slide is aligned with the tipping mechanism 20 on the side of the gantry body. When the dry and wet coal sweeping assembly 1 slides to the specified position of the tipping mechanism, it can be accurately docked to ensure that the coal slag can be smoothly unloaded into the feed port of the tipping mechanism 20.

[0062] The driving mechanism includes a reduction box 211 and a motor 212. The motor 212 is connected to the input shaft of the reduction box 211 through an output shaft. The high-speed rotation provided by the motor 212 is decelerated by the reduction box 211. The motor 212 can adopt a servo motor or a stepper motor to achieve precise control. The gear set inside the reduction box 211 has been precisely designed to effectively reduce the motor speed while greatly increasing the torque output to meet the needs of the drive wheel. The housing of the reduction box 211 is fixed to the main body of the gantry. Through precise installation and calibration, the coaxiality and stability of the transmission are guaranteed to prevent vibration and noise from affecting the system. The output shaft of the reduction box 211 is connected to the drive wheel 210 through a coupling to ensure smooth power transmission and reduce mechanical wear and reduced transmission efficiency due to axis deviation.

[0063] Example 3

[0064] Based on Example 2, pulleys are installed on both sides of the bottom of the dry and wet coal sweeping assembly 1. The pulleys are made of high-strength materials such as steel or engineering plastics, and their rims are designed to be V-shaped or U-shaped to match the shape of the slideway, ensuring that they can adapt to the path of the slideway during sliding and reduce lateral deviation.

[0065] Specifically, the pulley is fixed to the bottom support structure of the dry and wet coal sweeping assembly 1 through a bearing seat and a bracket. Multiple pulleys are arranged on both sides of the dry and wet coal sweeping assembly 1 to evenly distribute the load. The bracket is precisely positioned and calibrated to ensure that the pulley runs smoothly on the slide. Ball bearings or roller bearings are installed inside the pulley to reduce sliding friction and improve sliding efficiency, ensuring that the dry and wet coal sweeping assembly 1 slides smoothly on the slide.

[0066] The dry and wet coal sweeping assembly 1 adopts the same drive structure as the gantry 21, and the reducer uses a planetary reducer or a worm gear reducer, and the specific selection depends on the reduction ratio and torque requirements required by the system. The reducer converts the high speed of the motor into the low speed and high torque required by the pulley to ensure the smooth sliding of the dry and wet coal sweeping assembly 1. The output shaft of the reducer is connected to the pulley through a coupling, and the output shaft of the drive motor is connected to the input shaft of the reducer. The same drive form helps to achieve better synchronous control and overall coordination, and improve the operating efficiency and stability of the system.

The two rotary buffer components 101 are provided with a connecting rod arm 1010 extending away from the front end of the coal storage box 110, and a vertical sweeping brush is installed on the connecting rod arm 1010 of each rotary buffer component 101. The vertical sweeping brush mechanism 10 is used to adjust the width of the two vertical sweeping brushes to adapt to the width of the coal car compartment, gather the coal cleaned on the compartment wall and the ground to the front end of the shovel plate, and buffer the cleaning process of the vertical sweeping brush; the two vertical sweeping brushes and the two rotary buffer components 101 move closer to or farther away from each other along the adjustment trajectory line of the width adjustment component 10.

[0071] The negative suction and gravity sedimentation mechanism 12 includes a negative suction lifting assembly 120 arranged at the bottom of the coal storage box 110 and a gravity sedimentation chamber 121 arranged above the negative pressure area 1100 of the coal storage box 110. The negative suction lifting assembly 120 includes a front roller brush assembly 1200 located between the flexible shovel plate 1100 and two vertical sweeping brushes, a rear roller brush assembly 1201 located at the front end of the discharge port of the coal storage box 110, and a negative suction port located at the front end of the rear roller brush assembly 1201. The negative suction port is connected to the gravity sedimentation chamber 121 through a pipeline. The negative suction and gravity sedimentation mechanism 13 is used to sweep the dry and wet residual coal gathered by the vertical sweeping brush into the flexible shovel plate 1100 by the front roller brush assembly 1200, and send the dry and wet residual coal that has not been cleaned on the ground into the gravity sedimentation chamber 121 by the rear roller brush assembly 1201 and the negative suction port for coal and gas separation.

[0072] The filtering and dust removal mechanism 13 is installed at the upper end of the negative pressure zone 1100 of the coal storage box 110, and is used to filter and purify the gas mixed with a very small amount of coal powder separated by the gravity sedimentation chamber 121 and discharge it into the atmosphere, and to regularly pulse dust removal of the coal powder attached to the filter toward the bottom of the negative pressure zone 1100 of the coal storage box 110.

[0073] The dry and wet coal sweeping operation unit of the present invention combines the flexible movement of the gantry with the automatic flipping and unloading design. Through the slideway set on the top of the gantry, the dry and wet coal sweeping assembly can slide accurately and dock with the tipping bucket mechanism to realize the automatic cleaning and transportation of coal slag. The tipping bucket mechanism adopts a top and side opening structure, with connecting rods and telescopic rods to ensure that the unloading process is stable and efficient, and avoid material blockage and loss. The entire system integrates multiple functional modules such as vertical sweeping brushes, flexible coal shovels, negative suction and gravity sedimentation, and filtering and dust removal, which not only improves the cleaning efficiency and operation flexibility, but also effectively controls the diffusion of coal dust and environmental pollution. This design significantly improves the degree of automation and overall operating efficiency of the equipment, reduces manual intervention, ensures the stability and safety of equipment operation, and adapts to a variety of complex working conditions.
