Description

Technical Field

[0001] This invention relates to the technology of cleaning cylindrical warehouses, specifically to a cylindrical warehouse cleaning machine and its cleaning method. Background Technology

[0002] Cylindrical silos are commonly used storage facilities in industries such as cement, steel, and coal. Due to factors such as leakage, internal and external temperature differences, production processes, and the characteristics of the materials, materials can accumulate and harden on the silo walls during storage. Over time, this buildup thickens and hardens, reducing the silo's volume and decreasing its efficiency. Furthermore, as the material thickens and weighs more, it eventually breaks off after overcoming the adhesion forces, forming lumps of varying sizes and shapes. During the discharge process, this can cause partial or complete blockage of the discharge outlets, resulting in a dead silo.

[0003] Currently, there are two main methods for cleaning cylindrical warehouses: one is manual cleaning, which is inefficient, time-consuming, labor-intensive, and prone to safety accidents; the other is mechanical cleaning, which is safe and efficient.

[0004] Existing silo cleaning equipment is mostly installed on the top of the silo and suspended inside the silo via flexible or rigid connections. The cleaning tools at the ends remove the wall-mounted material. Its disadvantages include: the need for additional openings in the silo top, which damages the silo's structural integrity, significantly reducing its strength, sealing, and overall integrity, severely impacting its future use.

[0005] This invention, through the design of the central turntable structure, allows direct entry from the feed inlet after removing the central feed chute at the top of the silo, without requiring additional openings to damage the civil structure. Furthermore, through the design of the structure and operation method of the silo entry section, installation, maintenance, and dismantling can all be completed on the top of the silo without personnel needing to enter it, allowing for the cleaning of materials on the silo walls while ensuring the integrity and smoothness of the walls. Summary of the Invention

[0036] As attached Figure 1 To be continued Figure 8 As shown:

[0037] Example 1:

[0038] This invention provides a cylindrical warehouse cleaning machine and a cleaning method thereof, including a cylindrical warehouse cleaning machine comprising:

[0039] Power and control components, including a hydraulic station and a control cabinet;

[0040] The central turntable mechanism 1 is installed on the top feed inlet of the silo cleaning machine and is driven to rotate by an electric motor or a hydraulic motor. The central turntable mechanism 1 is equipped with a turntable extension section 4, a first rotating auxiliary rod 61 and a second rotating auxiliary rod 62.

[0041] The main boom body 8 enters the warehouse of the cleaning machine vertically through the maintenance door on the top of the warehouse. A control valve 86 is installed in the middle of the main boom body 8. The first telescopic arm 91 and the second telescopic arm 92 are connected to both ends of the main boom body 8. Multiple process holes 82 are opened on the main boom body 8.

[0042] Furthermore, the hydraulic station and control cabinet are placed on the top of the cylindrical silo. The hydraulic station is suspended inside the cylindrical silo via two oil pipes and connected to the control valve 86 on the main boom body 8. The control cabinet is suspended inside the cylindrical silo via a control cable and connected to the control valve 86. The control valve 86 is reinforced by an auxiliary reinforcement cover 81. The main boom body 8 is placed horizontally or inclined inside the cylindrical silo by the first winch 21 and the second winch 22 via the first wire rope 31 and the second wire rope 32.

[0043] Vertical plane 75 and support point 76, main boom flange 73 is connected to main boom body 8, multiple lifting lugs 701 are connected to main boom body 8, main boom flange 73 and main boom body 8 are reinforced by multiple lifting lugs 701, first cantilever 71 and second cantilever 72 are installed on lifting lug 701 through mounting holes 74.

[0044] Furthermore, the other ends of the first wire rope 31 and the second wire rope 32 away from the first winch 21 and the second winch 22 are fixed to the first cantilever 71 and the second cantilever 72 through the second guide rope pulley 12, the third guide rope pulley 13, the turntable extension section 4, the first guide rope pulley 5, the first rotating auxiliary rod 61 and the second rotating auxiliary rod 62.

[0045] The turntable base 16 is provided with a guide rope pulley frame 11, a second guide rope pulley 12, a third guide rope pulley 13, a motor 14, and a support bearing 15.

[0046] The winch assembly includes a winch base 221, on which a first winch 21 and a second winch 22 are fixedly mounted. The winch base 221 is fixed to the top surface of the cylindrical silo by a first expansion bolt 222 and a second expansion bolt 223. The ends of the first winch 21 and the second winch 22 are respectively connected to a first wire rope 31 and a second wire rope 32.

[0047] Working principle: The power and control components are the power source and control core of the warehouse clearing machine. The hydraulic station and control cabinet are placed on the top of the warehouse clearing machine. This layout saves space on the main boom body 8 and facilitates external monitoring and maintenance by the operator. The hydraulic station is suspended inside the warehouse through two oil pipes and connected to the control valve 86 on the main boom body 8. It delivers hydraulic oil to the control valve 86 at a certain pressure and flow rate, providing power to the hydraulic system of the entire equipment. The control cabinet is connected to the control valve 86 through the control cable. The operator can send control signals to the control valve 86 from outside the warehouse through the control cabinet to precisely regulate the flow direction, pressure and flow rate of the hydraulic oil, thereby controlling the action of various hydraulic components of the equipment, such as the lifting and lowering of the main boom, the extension and retraction of the telescopic boom, and the crushing action of the breaker hammer, so as to achieve comprehensive control over the operating status of the warehouse clearing machine.

[0048] The central turntable mechanism 1 is installed on the top feed inlet of the cylindrical silo. It is driven to rotate by an electric motor or hydraulic motor. The electric motor or hydraulic motor transmits power to the central turntable mechanism 1, causing it to rotate around the central axis. The turntable extension section 4, the first rotating auxiliary rod 61 and the second rotating auxiliary rod 62 set on the turntable not only enhance the strength and stability of the turntable, but also play a role in auxiliary guidance and balance during rotation, ensuring that the turntable rotates smoothly. The main boom body 8 is connected to the central turntable mechanism 1. As the turntable rotates, the main boom body 8 can rotate 360 ​​degrees in the horizontal direction, thereby covering various areas inside the cylindrical silo and realizing cleaning operations in different directions.

[0049] The winch assembly plays a crucial role in positioning the main boom. The winch base 221 is firmly fixed to the top surface of the cylindrical silo by the first expansion bolt 222 and the second expansion bolt 223, ensuring the stability of the winch during operation. The first winch 21 and the second winch 22 are respectively connected to the first wire rope 31 and the second wire rope 32. The other end of the wire rope is fixed to the first cantilever 71 and the second cantilever 72 by the second guide rope pulley 12, the third guide rope pulley 13, the turntable extension section 4, the first guide rope pulley 5, the first rotating auxiliary rod 61 and the second rotating auxiliary rod 62. When the winch is started, by winding and unwinding the wire rope, the main boom body 8 can be pulled, so that it is placed horizontally or inclined in the silo under the action of the first winch 21 and the second winch 22, realizing the precise adjustment and fixation of the main boom position to meet the needs of different cleaning heights and angles.

[0050] The main boom body 8 enters the silo vertically through the maintenance door on the top of the cylindrical silo. It has multiple process holes 82. The design of the process holes 82 not only reduces the weight of the main boom and the overall load of the equipment, but also facilitates the installation of other components and the layout of wiring, thereby improving the assembly efficiency and maintainability of the equipment. The control valve 86 installed in the middle of the main boom body 8 is reinforced by an auxiliary reinforcement cover 81 to prevent the control valve 86 from being damaged due to vibration or collision during equipment operation, thus ensuring the normal operation of the hydraulic system.

[0051] The main boom body 8 has a stable and reliable support structure. The main boom body 8 is connected to the main boom flange 73 and reinforced by multiple lifting lugs 701. The lifting lugs 701 are equipped with a first cantilever 71 and a second cantilever 72 through mounting holes 74. The first cantilever 71 and the second cantilever 72 are connected to the wire rope, which provides additional support for the main boom, enhances the stability of the main boom in horizontal or inclined states, prevents the main boom from shaking or deforming during operation, and ensures the safe operation of the equipment.

[0052] With the above technical solution, the hydraulic station and control cabinet in the power and control components are placed on the top of the cylindrical silo. This layout design is ingenious and reasonable. The hydraulic station is connected to the control valve 86 on the main boom body 8 through two oil pipes hanging inside the silo. It can stably provide power to the hydraulic components of the silo cleaning machine, ensuring that the equipment has sufficient and continuous power during operation. The control cabinet is connected to the control valve 86 through a control cable. The operator can accurately control the equipment outside the silo, realize real-time monitoring and flexible adjustment of the silo cleaning machine's operating status, greatly improve the convenience and accuracy of operation, and effectively avoid the problems of low work efficiency or equipment damage caused by inconvenient operation or inaccurate control.

[0053] The central turntable mechanism 1 is installed on the top feed inlet of the cylindrical silo. It is driven to rotate by an electric motor or hydraulic motor, which allows the main arm body 8 to rotate flexibly 360 degrees around the center. The turntable extension section 4, the first rotation auxiliary rod 61 and the second rotation auxiliary rod 62 set on the turntable further enhance the stability and smoothness of the turntable. In the silo cleaning operation, this flexible rotation function enables the equipment to clean all directions inside the cylindrical silo, avoiding the occurrence of cleaning dead corners, greatly improving the comprehensiveness and thoroughness of the cleaning, and ensuring that the materials and attachments inside the cylindrical silo are efficiently removed.

[0054] The main boom 8 enters the silo vertically through the maintenance door on the top of the cylindrical silo. The control valve 86 installed in the middle is reinforced by an auxiliary reinforcement cover 81, ensuring the stability and safety of the control valve 86 during operation and reducing the risk of damage to the control valve 86 due to vibration or collision. The multiple process holes 82 opened on the main boom 8 not only reduce the weight of the main boom and the overall load of the equipment, but also facilitate the installation of other components and the layout of wiring, improving the assembly efficiency and maintainability of the equipment. The main boom 8 is placed horizontally or inclined in the silo by the first winch 21 and the second winch 22 through the first wire rope 31 and the second wire rope 32. This arrangement allows the main boom to be flexibly adjusted according to different silo cleaning needs and the silo environment, enhancing the adaptability of the equipment to various complex working conditions.

[0055] The main boom flange 73 connected to the main boom body 8 is reinforced with the main boom by multiple lifting lugs 701. The first cantilever 71 and the second cantilever 72 installed on the lifting lugs 701 through the mounting holes 74 provide a stable support structure for the main boom. During the cleaning operation, this stable support can effectively withstand the weight of the main boom and the working tools and the impact force generated during the operation, prevent the main boom from shaking or deforming, ensure the stability and safety of the equipment during operation, greatly reduce the probability of safety accidents, and protect the personal safety of the operators.

[0056] The guide rope pulley frame 11, the second guide rope pulley 12, the third guide rope pulley 13, the motor 14, and the support bearing 15 installed on the turntable base 16 together constitute a precise guiding and transmission system. The guide rope pulley can accurately guide the movement direction of the first wire rope 31 and the second wire rope 32, ensuring that the wire rope does not deviate or entangle during transmission, thus ensuring the smoothness and reliability of transmission. The motor 14 provides power to the entire transmission system, while the support bearing 15 reduces the friction when the turntable rotates, further improving the operating efficiency and stability of the equipment, enabling the equipment to complete the warehouse cleaning operation efficiently and stably.

[0057] The winch base 221 in the winch assembly is firmly fixed to the top surface of the cylindrical silo by the first expansion bolt 222 and the second expansion bolt 223, ensuring the stability of the winch during operation. The first winch 21 and the second winch 22 are connected to the main boom by the first wire rope 31 and the second wire rope 32, which can precisely control the lifting and lowering and position adjustment of the main boom. The operator can conveniently adjust the running speed and force of the winch according to the actual needs of the silo cleaning operation, so as to achieve precise positioning of the main boom and enable the working tools to accurately reach the position to be cleaned, thereby improving the accuracy and efficiency of the silo cleaning operation.

[0058] Example 2:

[0059] This embodiment is basically the same as the previous embodiment, except that the telescopic section operation tool assembly includes a carrier flange 95, a breaker arm 100 is mounted on the carrier flange 95, a second breaker hammer 909 is mounted on the breaker arm 100, an extension chisel 910 is connected to the second breaker hammer 909, a breaker arm cylinder 99 is provided on the breaker arm 100, a connecting rod 908 is provided on the breaker arm cylinder 99, the angle of the breaker hammer is adjusted by the breaker arm cylinder 99 and the connecting rod 908, and lifting ring bodies 903 are provided at both ends of the breaker arm 100.

[0060] Furthermore, the outer and inner walls of the first telescopic arm 91 and the second telescopic arm 92 are respectively provided with an inner telescopic tube 98 and an outer telescopic tube 97. A carrier flange 95 is installed at the front end of the inner telescopic tube 98, and the tail end of the inner telescopic tube 98 is reinforced by welding a main arm flange 73 and reinforcing plate 93. A milling head body 101 is provided at one end of the first telescopic arm 91. The milling head body 101 is connected to the carrier flange 95 through a milling head main arm 911. A milling lifting ring 913 is provided on the milling head main arm 911. A roller 912 is installed at the end of the milling head body 101. A first breaker hammer 102 is provided at the end of the second telescopic arm 92. A limit tube 906 is provided inside the inner telescopic tube 98. A limit sleeve 905 is provided on the limit tube 906. A limit cap 907 is provided at the end of the limit tube 906. A reinforcing hole 94 is opened on the reinforcing plate 93, and a flange bolt 96 is connected to the carrier flange 95.

[0061] Working principle: The first telescopic boom 91 and the second telescopic boom 92 achieve telescopic function through the cooperation of the inner tube 98 and the outer tube 97 of the telescopic section. The inner tube 98 can slide inside the outer tube 97 of the telescopic section. The telescopic movement of the inner tube 98 is controlled by the hydraulic system. The front end of the inner tube 98 is equipped with a carrier flange 95 for connecting various working tools, such as the breaker arm 100 and the milling head body 101. The tail end of the inner tube 98 is reinforced by welding the main boom flange 73 and reinforcing plate 93. The reinforcing plate 93 has reinforcing holes 94, which further enhances the connection strength between the telescopic boom and the main boom, ensuring that the connection between the telescopic boom and the main boom is stable during telescopic and working processes and can withstand the huge force generated by the working tools.

[0062] The limiting tube 906, the limiting sleeve 905 and the limiting cap 907 installed inside the inner tube 98 of the telescopic section form a limiting device. When the telescopic arm extends or retracts, the limiting sleeve 905 slides on the limiting tube 906, which plays a guiding and limiting role, preventing the telescopic arm from extending or retracting excessively or coming off, and ensuring the safety and reliability of the telescopic arm's extension and retraction.

[0063] The breaker arm 100 in the telescopic section operation tool assembly is mounted on the carrier flange 95. A second breaker hammer 909 is mounted on the breaker arm 100, and an extension chisel 910 is connected to the second breaker hammer 909. A breaker arm cylinder 99 is set on the breaker arm 100, and a connecting rod 908 is set on the breaker arm cylinder 99. By controlling the extension and retraction of the breaker arm cylinder 99, the connecting rod 908 can be driven to move, thereby adjusting the angle of the breaker hammer so that the breaker hammer can perform breaker operation on hard materials in the cylindrical silo at the optimal angle. The lifting ring body 903 set at both ends of the breaker arm 100 facilitates the lifting and handling of the equipment. The first breaker hammer 102 is set at the end of the second telescopic arm 92, which can crush materials at different positions, improving the efficiency and flexibility of the breaker operation.

[0064] The milling head body 101 at one end of the first telescopic arm 91 is connected to the carrier flange 95 through the milling head main arm 911. The milling head main arm 911 is equipped with a milling lifting ring 913 to facilitate the installation and disassembly of the milling head. A roller 912 is installed at the end of the milling head body 101. When the equipment is running, the roller 912 rotates at high speed to perform milling operations on the inner wall of the cylindrical silo, remove the attached materials on the inner wall, and restore the inner wall of the silo to a flat and clean state.

[0065] Through the above technical solution, the carrier flange 95 of the telescopic section operation tool assembly is equipped with a variety of operation tools to meet the cleaning needs of different types of materials and attachments. The second breaker hammer 909 and the extended chisel 910 installed on the breaker arm 100 can powerfully crush relatively hard materials in the cylindrical silo. The cooperation between the arm cylinder 99 and the connecting rod 908 can flexibly adjust the angle of the breaker hammer to adapt to crushing operations at different angles, improving the flexibility and efficiency of the crushing operation. The milling head body 101 set at one end of the first telescopic arm 91 connects with the carrier flange 911 through the milling head main arm 911. With flange 95 connection, the roller 912 installed at the end of the milling head body 101 can efficiently mill the inner wall of the cylindrical silo and remove the attached materials; the first breaker 102 set at the end of the second telescopic arm 92 can be used to crush general materials. The design of the inner tube 98 and the outer tube 97 of the telescopic section allows the telescopic arm to be extended and adjusted according to the operation needs, expanding the working range. The internal limit tube 906, limit sleeve 905 and limit cap 907 ensure the stability and safety of the telescopic arm during the extension and retraction process, prevent the telescopic arm from being overextended or dislodged, and ensure the normal operation of the equipment.

[0066] Example 3:

[0067] This embodiment is basically the same as the previous embodiment, except that the lighting monitoring component includes a lighting cover 901, the interior of the lighting cover 901 is provided with a lighting cover mounting hole 902, and a monitoring camera 904 is installed on the top of the lighting cover 901.

[0068] Working principle: The lighting monitoring component provides excellent visual conditions and safety assurance for warehouse cleaning operations. The lighting lamp cover 901 is equipped with lighting fixtures. The lighting lamp cover 901 can be installed in a suitable position through the lamp cover hoisting hole 902, providing sufficient light to the warehouse work area. This allows operators to clearly observe the work situation in a bright environment, improving the accuracy and safety of the operation. The monitoring camera 904 installed on the top of the lighting lamp cover 901 can monitor the warehouse operation in real time and transmit the image to the control cabinet or external display screen. Operators can view the monitoring screen to understand the work progress, equipment operating status, and changes in the warehouse environment in a timely manner. Once an abnormality is detected, measures can be taken quickly to deal with it, effectively avoiding the occurrence of safety accidents and ensuring the smooth progress of warehouse cleaning operations.

[0069] Through the above technical solution, the lighting cover 901 in the lighting monitoring component provides sufficient light for the warehouse cleaning operation area, enabling operators to work in a bright environment, improving the clarity and accuracy of the operation. The monitoring camera 904 installed on the top of the lighting cover 901 can monitor the operation inside the warehouse in real time and transmit the image to the control cabinet or external display screen. Operators can view the monitoring screen to understand the progress of the operation, the operating status of the equipment, and changes in the warehouse environment in a timely manner. Once an abnormality is found, measures can be taken quickly to deal with it, effectively avoiding the occurrence of safety accidents and ensuring the safe and smooth progress of the warehouse cleaning operation.

[0079] For the installation of the lighting monitoring components, the lighting cover 901 is installed in a suitable position through the lamp cover mounting hole 902, the lighting fixture is installed inside the lighting cover 901, the monitoring camera 904 is installed on the top of the lighting cover 901, and the relevant lines are connected to ensure that the lighting and monitoring functions are normal.

[0080] For overall commissioning, start the hydraulic station and control cabinet, and check if the hydraulic system pressure is normal and if the control signals can accurately control the actions of each hydraulic component, such as the lifting and lowering of the main boom and the extension and retraction of the telescopic boom. Start the electric motor or hydraulic motor to drive the central turntable mechanism 1 to rotate, and check if the rotation is smooth and if there is any abnormal noise. Start the winch and check if the wire rope winding and unwinding is smooth, and whether the main boom body 8 can be placed horizontally or inclined inside the cylindrical silo under the action of the first winch 21 and the second winch 22. Check if the lighting and monitoring systems are working properly.

[0081] Step 2: Position and adjust the main boom body 8. Operate the control cabinet and control the first winch 21 and the second winch 22 to start via control signals. Unwind the first wire rope 31 and the second wire rope 32 to pull the main boom body 8, so that the main boom body 8 is placed horizontally or inclined inside the cylindrical silo under the action of the first winch 21 and the second winch 22. Adjust the main boom body 8 to a suitable position and angle according to the silo cleaning operation requirements.

[0082] During the adjustment process, observe the stability of the main boom body 8 to ensure that the connection between the main boom body 8 and the wire rope through the first cantilever 71 and the second cantilever 72 is stable, and that the main boom flange 73 and the main boom body 8 are reliably reinforced through the lifting lug plate 701 to prevent the main boom body 8 from shaking or deforming during operation.

[0083] Step 3: Perform inventory clearance.

[0084] Rotation to cover the work area: Start the electric motor or hydraulic motor to drive the central turntable mechanism 1 to rotate. The central turntable mechanism 1 drives the main boom body 8 to make a circular motion around the central axis, so that the main boom body 8 can rotate 360 ​​degrees in the horizontal direction, thereby covering all areas inside the cylindrical warehouse.

[0085] Telescopic boom operation: Based on the location and condition of materials and attachments within the storage area, the extension and retraction of the first telescopic boom 91 and the second telescopic boom 92 are controlled via a hydraulic system. The inner tube 98 of the telescopic section slides within the outer tube 97 of the telescopic section, enabling the extension and retraction of the telescopic boom and delivering work tools (such as breakers, milling heads, etc.) to the location requiring cleaning. During the extension and retraction process, the limiting sleeve 905 slides on the limiting tube 906, serving as a guide and limiter to prevent the telescopic boom from over-extending or disengaging.

[0086] Crushing operation: If the second breaker 909 on the breaker arm 100 or the first breaker 102 at the end of the second telescopic arm 92 is used for crushing, the extension and retraction of the arm cylinder 99 is controlled to drive the connecting rod 908 to move, adjusting the angle of the breaker so that the breaker can crush the hard material in the cylindrical silo at the optimal angle. For deeper areas, the extended chisel 910 is used for crushing.

[0087] Milling operation: If the milling head body 101 at one end of the first telescopic arm 91 is used for milling operation, start the roller 912 at the end of the milling head body 101 to make the roller 912 rotate at high speed to mill the inner wall of the cylindrical warehouse and remove the attached materials from the inner wall.

[0088] Step 4: Monitor and adjust the warehouse cleaning operation. Operators can monitor the warehouse operation in real time by viewing the images transmitted from the 904 monitoring camera to the control cabinet or external display screen, including the operation progress, equipment operating status and changes in the warehouse environment.

[0089] Based on the monitoring footage, once any abnormalities are detected, such as equipment malfunctions or abnormal material accumulation, immediate measures are taken to address them. For example, adjusting the position and angle of the main boom 8, changing the telescopic boom's extension length, and adjusting the working parameters of the tools are all done to ensure the smooth progress of the warehouse clearing operation.

[0090] Step 5: After the warehouse cleaning operation is completed, stop the operation of all tools (breaker hammer, milling head, etc.), and retract the first telescopic arm 91 and the second telescopic arm 92 through the hydraulic system, so that the inner tube 98 of the telescopic section returns to the appropriate position inside the outer tube 97 of the telescopic section.

[0091] Operate the control cabinet to control the first winch 21 and the second winch 22 to rotate in opposite directions, and to wind up and unwind the first wire rope 31 and the second wire rope 32. Slowly pull back the main boom body 8 and adjust it to a vertical position. Take the main boom body 8 out of the silo through the maintenance door on the top of the silo.

[0092] Shut down the hydraulic station and control cabinet, disconnect the power supply, clean and maintain the equipment, and prepare it for the next use.
