Description

Technical Field

[0001] This invention relates to the field of cement silo cleaning technology, and in particular to a cement silo cleaning device and operating method. Background Technology

[0002] The cement stored in the cement silo is a powdery material. Due to factors such as excessively high temperature when the stored material enters the silo, excessive storage time, moisture, and water ingress, the cement silo walls, bottom, and discharge port become caked and arched in many places, causing a decrease in the effective storage capacity of the silo and making it impossible to load and unload materials normally. If it is not cleaned in time, the material will become thicker and thicker, causing the local diameter and volume of the cement silo to decrease. The volume of cement that the cement silo can hold will gradually shrink, and the utilization efficiency of the cement silo will decrease. Sometimes, the attached material will also fall off on its own and become blocks or flakes of different sizes mixed with the cement powder. This can cause blockage of the discharge device or, in severe cases, arch and bulge on the funnel inside the silo, preventing the material from being discharged and causing material shortages and production stoppages.

[0003] Existing technologies typically employ manual cleaning, but this method is inefficient, time-consuming, labor-intensive, and poses safety hazards. Therefore, mechanical devices are now used to replace manual labor for cleaning the inner walls of cement silos, allowing for real-time cleaning. However, the following technical problems still exist.

[0004] (1) In existing silo cleaning devices, the main beam assembly is usually connected to the winch by a wire rope. The height of the main beam assembly relative to the cement silo is controlled by controlling the length of the wire rope connected to the winch, as well as the distance that the broken parts move up and down on the inner wall of the cement silo. However, if the length of the wire rope is too long, the broken parts will swing continuously during the movement, making it difficult for the silo cleaning device to accurately control the movement of the broken parts to the position where the material is hung for cleaning.

[0005] (2) The cement powder in the cement silo contains lumps, which are easy to block the discharge port. However, it is impossible to manually crush the lumps so that the cement powder in the cement silo can flow out smoothly.

[0006] (3) In the prior art, the mechanical device for cleaning the cement silo is to install a cantilever on the main beam and install a crushing component at the front end of the cantilever. The cantilever swings to drive the crushing component to remove cement lumps on the inner wall of the cement silo. However, the cleaning range of the cantilever in this mechanical device is relatively small. Summary of the Invention

[0007] The purpose of this invention is to provide a cement silo cleaning device and operating method to solve the above-mentioned technical problems existing in the prior art. The main contents are as follows:

[0008] This application provides a cement silo cleaning device, comprising:

[0009] A lifting assembly is mounted on the top wall of the cement silo and is rotatable relative to the cement silo.

[0010] The main beam assembly is connected to the supporting assembly, and a portion of the main beam assembly extends into the cement silo; the length of the main beam assembly is adjustable.

[0011] A blasting assembly, connected to the main beam assembly, the blasting assembly including a blasting element used to clear cement lumps in the cement silo;

[0012] A wall cleaning assembly is installed inside the cement silo. The wall cleaning assembly includes a cantilever and a crushing component. One end of the cantilever is hinged to the main beam assembly, and the other end of the cantilever is connected to the crushing component. The cantilever includes a first cantilever and a second cantilever, wherein one end of the first cantilever is hinged to the main beam assembly, and the other end of the first cantilever is hinged to the second cantilever.

[0013] A drive assembly that drives the main beam assembly to swing relative to the support assembly, or the drive assembly drives the first cantilever to swing relative to the main beam assembly, and / or the drive assembly drives the second cantilever to swing relative to the first cantilever.

[0014] Furthermore, the main beam assembly includes multiple main beam units, and adjacent main beam units are detachably connected.

[0015] Furthermore, the main beam assembly is flexibly connected to the support assembly via connectors.

[0016] Furthermore, the number of cantilever arms is two, and the drive assembly drives the angle between the first cantilever arm and / or the second cantilever arm and the main beam assembly, causing the main beam assembly to swing in a preset direction.

[0017] Furthermore, the lifting assembly includes: a lifting bracket, the lifting bracket being located above the cement silo, the lifting bracket including two first support frames symmetrically arranged along the axial direction of the main beam assembly, the two sides of the two first support frames being connected by second support frames respectively; the space between the two opposing second support frames forms a swing groove, and part of the main beam assembly is located in the swing groove.

[0018] Furthermore, the blasting assembly is located between the two cantilever arms, and the blasting assembly also includes a mounting base connected to the lower end of the main beam assembly, and the mounting base is provided with a clamping channel, in which the blasting component is installed.

[0019] Furthermore, the length of either the first cantilever or the second cantilever is less than the radius of the cement silo.

[0020] Furthermore, the first cantilever and the second cantilever are hollow structures, and the cross-sections of the first cantilever and the second cantilever are inverted triangles.

[0021] Furthermore, the cantilever also includes a first reinforcing member disposed in the first cantilever and a second reinforcing member disposed in the second cantilever; and the first reinforcing member and the second reinforcing member are disposed adjacent to each other.

[0022] This application also provides an operating method for a cement silo cleaning device, which includes the following steps:

[0023] The positions of the first cement block and the second cement block in the cement silo are obtained, wherein the first cement block is a cement block in the cement in the cement silo, and the second cement block is a cement block on the inner wall of the cement silo.

[0024] Based on the position of the first cement block, the length of the main beam assembly is adjusted to move the blasting assembly along the axial direction of the cement silo; the lifting assembly is adjusted to drive the blasting assembly to rotate circumferentially along the cement silo; the drive assembly is controlled to drive the main beam assembly to swing the blasting assembly radially along the cement silo; thereby enabling the blasting assembly to reach the position of the first cement block and blast the first cement block.

[0025] Based on the position of the second cement block, the lifting assembly is adjusted to drive the wall-cleaning assembly to rotate circumferentially along the cement silo; the length of the main beam assembly is adjusted to move the wall-cleaning assembly axially along the cement silo; thereby enabling the wall-cleaning assembly to reach the position of the second cement block and break it up.

[0026] Compared with the prior art, the present invention has at least the following technical effects:

[0027] (1) The lifting assembly can rotate relative to the cement silo, allowing the blasting assembly and the wall-cleaning assembly to rotate circumferentially along the cement silo; the length of the main beam assembly can be adjusted, allowing the blasting assembly and the wall-cleaning assembly to move axially along the cement silo; the wall-cleaning assembly is designed as a foldable structure, allowing it to move radially along the cement silo. By adjusting the positions of the blasting assembly and the wall-cleaning assembly in the axial, radial, and axial directions using the silo-cleaning device, all-round cleaning of cement clumps in the cement silo can be achieved, allowing cement powder to flow smoothly out of the cement silo.

[0028] (2) The length of the main beam assembly is adjustable, while the distance between the main beam assembly and the support assembly remains constant. This allows the wall cleaning assembly and the blasting assembly to move along the axial direction of the cement silo, while the distance between the main beam assembly and the support assembly remains constant. This avoids the main beam assembly from shaking significantly when the distance between the main beam assembly and the support assembly is adjusted too much. At the same time, it can clean cement clumps on the inner wall of the cement silo at different depths. Attached Figure Description

[0049] like Figures 1-14 As shown, this application provides a cement silo cleaning device, comprising:

[0050] The lifting assembly 10 is disposed on the top wall of the cement silo 100 and is rotatable relative to the cement silo 100.

[0051] The main beam assembly 20 is connected to the supporting assembly 10, and a portion of the main beam assembly 20 extends into the cement silo 100. The length of the main beam assembly 20 is adjustable.

[0052] A blasting assembly 40 is connected to the main beam assembly 20. The blasting assembly 40 includes a blasting element 41, which is used to clear cement lumps in the cement silo 100.

[0053] A wall cleaning assembly 30 is disposed within the cement silo 100. The wall cleaning assembly 30 includes a cantilever 31 and a crushing component 32. One end of the cantilever 31 is hinged to the main beam assembly 20, and the other end of the cantilever 31 is connected to the crushing component 32. The cantilever 31 includes a first cantilever 311 and a second cantilever 312, wherein one end of the first cantilever 311 is hinged to the main beam assembly 20, and the other end of the first cantilever 311 is hinged to the second cantilever 312.

[0054] A drive assembly that drives the main beam assembly 20 to swing relative to the support assembly 10, or the drive assembly drives the first cantilever 311 to swing relative to the main beam assembly 20, and / or the drive assembly drives the second cantilever 312 to swing relative to the first cantilever 311.

[0055] It should be noted that: the cement lumps in the cement silo 100 are the first cement lumps, and the cement lumps on the inner wall of the cement silo 100 are the second cement lumps. The blasting component 40 is used to blast the first cement lumps in the cement silo 100, and the wall clearing component 30 is used to crush the second cement lumps in the cement silo 100.

[0056] In the above scheme, this application installs the lifting assembly 10 above the top wall of the cement silo 100, such as... Figure 1 As shown, the top wall of the cement silo 100 is the outer surface of the top, and the lifting assembly 10 is used to provide tension to the main beam assembly 20. The lifting assembly 10 is a frame structure, which facilitates processing and manufacturing and reduces the weight of the lifting assembly 10 itself. Specifically, the lower end of the lifting assembly 10 is installed on the top wall of the cement silo 100, and the lifting assembly 10 can rotate relative to the cement silo 100, thereby driving the main beam assembly 20 to rotate, so that the wall cleaning assembly 30 can rotate in all directions to break up and clean the second cement block in the cement silo 100, and the blasting assembly 40 can rotate in all directions to blast the first cement block in the cement silo 100.

[0057] The main beam assembly 20 provides an installation foundation for the wall cleaning assembly 30 and the blasting assembly 40. One end of the main beam assembly 20 is connected to the support assembly 10, and the other end is connected to the wall cleaning assembly 30 and the blasting assembly 40. Specifically, a first mounting seat 11 is provided on the top inner wall of the support assembly 10, and one end of the main beam assembly 20 is connected to the first mounting seat 11. By providing the first mounting seat 11 on the top inner wall of the support assembly 10, the main beam assembly 20 can be quickly installed in a preset position on the support assembly 10. The other end of the main beam assembly 20 is connected to the wall cleaning assembly 30 and the blasting assembly 40.

[0058] The length of the main beam assembly 20 in this application can be dynamically adjusted according to the position of the cement lumps on the inner wall of the cement silo 100. For example, if the first and second cement lumps on the inner wall of the cement silo 100 are at the top, the main beam assembly 20 is adjusted to its shortest length; if the first and second cement lumps on the inner wall of the cement silo 100 are at the bottom, the main beam assembly 20 is adjusted to its maximum length. By adjusting the length of the main beam assembly 20, the wall cleaning assembly 30 and the blasting assembly 40 are moved up and down in the axial direction of the cement silo 100 to the positions of the first and second cement lumps that need to be removed. During this process, it is not necessary to adjust the distance between the main beam assembly 20 and the first mounting seat 11 of the supporting assembly 10.

[0059] The blasting assembly 40 in this application is detachably connected to the main beam assembly 20, facilitating inspection and replacement of the blasting assembly 40. The detachable connection method includes, for example, nut and screw connections, snap-fit ​​connections, etc., and is not limited here. The blasting element 41 in the blasting assembly 40 is typically connected to the lower end of the main beam assembly 20 and coaxially mounted with it, ensuring that the blasting element 41 can swing at the same angle as the main beam assembly 20. The drive assembly can drive the main beam assembly 20 to swing relative to the supporting assembly 10 in a preset direction to the location of the first cement block and blast it.

[0060] It should be noted that the blasting component 41 in this application is a carbon dioxide fracturing device. If it is still impossible to blast the hard material, a pneumatic drill bit kit can be installed on the carbon dioxide fracturing device to drive the carbon dioxide fracturing device to penetrate the hard material.

[0061] The wall-cleaning assembly 30 is located inside the cement silo 100, facilitating the cleaning of cement clumps within the silo. The wall-cleaning assembly 30 includes a cantilever 31 and a crushing component 32. The cantilever 31 includes a first cantilever 311 and a second cantilever 312. Furthermore, the cantilever 31 may also include a third, fourth, fifth, etc., without limitation. By configuring the cantilever 31 to consist of the first cantilever 311 and the second cantilever 312, the cleaning range of the cantilever 31 driving the crushing component 32 can be expanded by allowing the first and second cantilever 311 to fold and extend through rotation. One end of the first cantilever 311 is hinged to the lower end / side of the main beam assembly 20. The drive assembly drives the first cantilever 311 to swing relative to the main beam assembly 20. The other end of the first cantilever 311 is hinged to one end of the second cantilever 312. The drive assembly can drive the second cantilever 312 to swing relative to the first cantilever 311. The other end of the second cantilever 312 is connected to the crushing component 32. The drive assembly can drive the first cantilever 311 and the second cantilever 312 respectively, or it can drive the first cantilever 311 and the second cantilever 312 simultaneously.

[0062] It should be noted that the drive component can be installed on the lifting component 10 or on the main beam component 20. There are no restrictions, as long as it can drive the wall cleaning component 30 and the blasting component 40.

[0063] Therefore, with the cement silo cleaning device provided in this application, the lifting assembly 10 can rotate relative to the cement silo 100, allowing the blasting assembly 40 and the wall-cleaning assembly 30 to rotate circumferentially along the cement silo 100; the length of the main beam assembly 20 can be adjusted, allowing the blasting assembly 40 and the wall-cleaning assembly 30 to move axially along the cement silo 100; and the wall-cleaning assembly 30 is configured as a foldable structure, allowing it to move radially along the cement silo 100. By adjusting the positions of the blasting assembly 40 and the wall-cleaning assembly 30 in the axial, radial, and circumferential directions, the cleaning of cement clumps in the cement silo 100 can be achieved from all directions.

[0064] Furthermore, Figures 1-6 As shown, the main beam assembly 20 includes a connecting plate 21, with a second mounting base 22 provided on the upper surface of the connecting plate 21. One end of the connector 60 is connected to the second mounting base 22, and the other end of the connector 60 is connected to the first mounting base 11. Through the second mounting base 22, the connector 60 can be quickly connected to the main beam assembly 20. It also includes multiple main beam units 23, which are detachably connected to each other. One end of the main beam unit 23 adjacent to the connecting plate 21 is fixedly connected to the connecting plate 21.

[0065] In the above scheme, the main beam assembly 20 is a frame structure, and the top of the main beam assembly 20 is a connecting plate 21, which facilitates the connection of the connector 60 to the main beam assembly 20. If the top of the main beam assembly 20 does not have a connecting plate 21, the connector 60 needs to be directly connected to any frame of the main beam assembly 20.

[0066] In this application, the length of the main beam assembly 20 is adjustable, specifically by increasing or decreasing the number of main beam units 23. Adjacent main beam units 23 are directly connected in a detachable manner to facilitate quick assembly and disassembly, such as through snap-fit ​​or threaded connections. Since the uppermost main beam unit 23 only needs to be connected to other main beam units 23 at one end and fixed at the other, the other end of the uppermost main beam unit 23 is fixedly connected to the connecting plate 21, for example, through welding or gluing.

[0067] Furthermore, adjacent main beam units 23 are nested together. The main beam unit 23 is made of aluminum alloy.

[0068] In the above scheme, adjacent main beam units 23 need to be connected to adjust the length of the main beam assembly 20. To facilitate connection, adjacent main beam units 23 are nested, allowing for quick connection. Figure 6As shown, each main beam unit 23 is a cuboid composed of one to four pipe columns. The diameter of the lower end of the pipe column used for connection in the upper main beam unit 23 is smaller than / greater than the diameter of the upper end of the pipe column used for connection in the lower main beam unit 23. They are connected in a nested manner. At the connection between two pipe columns, they can be fixed and positioned by setting concave and convex fits on the inner and outer walls, or by using internal and external threads, or by using pins.

[0069] In this application, it is preferable to open positioning holes 231 on the corresponding pipe columns. After the two pipe columns are nested and the two positioning holes 231 are aligned, the pin is inserted into the positioning hole 231 to realize the connection between the two adjacent main beam units. The connection is quick and convenient. Similarly, the disassembly between the two adjacent main beam units 23 is also quick and convenient. The pipe columns are provided with protrusions 232 to facilitate the nesting length of the two pipe columns to be too long.

[0070] Furthermore, the main beam assembly 20 is flexibly connected to the support assembly 10 via a connector 60.

[0071] In the above scheme, the main beam assembly 20 is flexibly connected to the first mounting base 11 through the connector 60. This allows the main beam assembly 20 to swing relative to the supporting assembly 10, thereby driving the blasting assembly 40 to swing radially along the cement silo 100 to reach the position of the first cement block. This avoids the risk of breakage when the main beam assembly 20 and the first mounting base 11 are rigidly connected, or the main beam assembly 20 not having a large swing range relative to the first mounting base 11.

[0072] The connector 60 can be a chain or a wire rope, etc. This application prefers a chain, which has a large pulling force on the main beam assembly 20; and the chain has a large contact area with the main beam assembly 20, so the main beam assembly 20 sways less during the extension and retraction process; at the same time, the chain is ring-shaped, which can be connected to the main beam assembly 20 and the first mounting base 11 by a snap-fit ​​method, which is simple and firm.

[0073] Furthermore, there are two cantilever arms 31, which are symmetrically arranged on both sides of the main beam assembly 20. The blasting assembly 40 is connected to the lower end of the main beam assembly 20 and is located between the two cantilever arms 31. The driving assembly drives the angle between the first cantilever arm 311 and / or the second cantilever arm 312 and the main beam assembly 20, causing the main beam assembly 20 to swing in a preset direction.

[0074] Furthermore, the drive assembly includes a first drive unit and a second drive unit. The first drive unit is connected to the first cantilever 311 to drive the first cantilever 311 to swing relative to the main beam assembly 20. The second drive unit is connected to the second cantilever 312 to drive the second cantilever 312 to swing relative to the first cantilever 311. In the above scheme, the first cantilever 311 and the second cantilever 312 are driven by two drive units respectively, which facilitates timely control of the first cantilever 311 and the second cantilever 312 and avoids operational control errors.

[0075] Furthermore, both the first drive unit and the second drive unit include a traction device 70 and a traction rope 50. One end of the traction rope 50 is connected to the traction device 70, and the other end is connected to the first cantilever 311 or the second cantilever 312. The traction device 70 drives the traction rope 50 to make the first cantilever 311 or the second cantilever 312 swing.

[0076] In the above scheme, the traction device 70 includes a first traction device 71 and a second traction device 72, and the traction rope 50 includes a first traction rope 51 and a second traction rope 52. The first traction device 71 and the second traction device 72 can be installed on the main beam assembly 20 or the support assembly 10. The first traction device 71 is connected to the first cantilever 311 through the first traction rope 51, and the first traction device 71 drives the first cantilever 311 to swing relative to the main beam assembly 20 by pulling the first traction rope 51. The second traction device 72 is connected to the second cantilever 312 through the second traction rope 52, and the second traction device 72 drives the second cantilever 312 to swing relative to the first cantilever 311 by pulling the second traction rope 52.

[0077] In this application, the first traction device 71 can also drive the first cantilever 311 to swing relative to the main beam assembly 20 by pulling the first traction rope 51, and / or, the second traction device 72 can be connected to the second cantilever 312 via the second traction rope 52, thereby changing the angle between the two cantilever 31s relative to the main beam assembly 20, causing the center of gravity of the main beam assembly 20 to shift, and driving the blasting component 40 to swing to a preset position. The swinging of the cantilever 31 drives the blasting component 40 to swing radially along the cement silo 100, blasting the first cement lumps in the cement silo 100, avoiding blockage of the discharge port of the cement silo 100. The two cantilever 31s set on the main beam assembly 20 enable the blasting component 40 to more accurately and quickly control the main beam assembly 20 to swing in a preset direction.

[0078] The cantilever 31 is hinged to the main beam assembly 20, and the cantilever 31 is controlled to swing to both sides of the main beam assembly 20 and fit into the main beam assembly 20, so that the cantilever 31 can easily enter and exit the cement silo.

[0079] Furthermore, the supporting assembly 10 includes a supporting bracket 12, which is located above the cement silo 100. The supporting bracket 12 includes two first support frames 24 symmetrically arranged along the axial direction of the main beam assembly 20. The two sides of the two first support frames 24 are respectively connected by second support frames 25. The space between the two opposing second support frames 25 forms a swing groove 26, and part of the main beam assembly 20 is located in the swing groove 26.

[0080] In the above scheme, such as Figure 8 As shown, the supporting assembly 10 includes a supporting bracket 12, which is a frame structure, and part of the main beam assembly 20 is located within the supporting bracket 12. The axial direction of the main beam assembly 20 is vertical. The supporting assembly 10 is a rectangular frame, including two first support frames 24 symmetrically arranged along the axial direction of the main beam assembly 20, and the two first support frames 24 are parallel. The two first support frames 24 are connected by a second support frame 25, and a gap is formed between the two opposing second support frames 25. This gap is a swing groove 26, in which the main beam assembly 20 can swing. The swing amplitude of the main beam assembly 20 in the width direction of the swing groove 26 is limited, while the main beam assembly 20 swings along the length direction of the swing groove 26.

[0081] The length direction of the swing groove 26 is parallel to the second support frame 25, and the width direction of the swing groove 26 is perpendicular to the length direction. The length 'a' of the swing groove 26 is the same as the length of the second support frame 25, and the width 'b' of the swing groove 26 is slightly larger than the width of the main beam assembly 20 in that direction. This results in a smaller swing amplitude of the main beam assembly 20 in the width direction of the swing groove 26, allowing the main beam assembly 20 to swing in a preset direction accurately to the location requiring blasting. The longer the length 'a' of the swing groove 26, the more accurately the main beam assembly 20 can swing in the preset direction, avoiding swinging in other directions.

[0082] It should be noted that the number of second support frames 25 can be two, four, eight, etc., and there is no limitation here; the direction of the second support frame 25 can be perpendicular to the axis of the main beam assembly 20, or it can be at an angle to the axis of the main beam assembly 20, and there is no limitation here.

[0083] Furthermore, the supporting assembly 10 has a receiving cavity 13, in which the main beam assembly 20 is partially located; and a turntable 14, which is installed at the lower end of the supporting bracket 12 and can drive the supporting bracket 12 to rotate relative to the cement silo 100.

[0084] In the above scheme, the supporting assembly 10 includes a supporting bracket 12, which is a frame structure. The internal space of the supporting bracket 12 forms a receiving cavity 13. Part of the main beam assembly 20 is located in the receiving cavity 13. When the main beam assembly 20 swings / shakes, it can only be in the receiving cavity 13, which makes the main beam assembly 20 easy to control. Without the receiving cavity 13, the main beam assembly 20 would easily swing to a large extent, causing the broken pieces 32 to have a strong impact on the inner wall of the cement silo 100.

[0085] A turntable 14 is fixedly installed at the lower end of the support bracket 12. A support base is provided at the lower end of the turntable 14, which is mounted on the top wall of the cement silo 100 via the support base. The turntable 14 can be driven to rotate by a gear transmission mechanism driven by a motor. The turntable 14 can also be driven to rotate by other driving components, and the type of driving component is not limited. In order to enable the crushing component 32 and the blasting component 41 to clean the cement lumps in the cement silo 100 from all directions, the turntable 14 is rotated to drive the support bracket 12 to rotate, which in turn drives the main beam assembly 20 to rotate, so that the crushing component 32 and the blasting component 41 rotate to different positions along the circumference of the cement silo 100 and clean those positions.

[0086] Furthermore, the blasting assembly 40 is located between the two cantilever 31, and the blasting assembly 40 also includes a mounting base 42, which is connected to the lower end of the main beam assembly 20, and the mounting base 42 is provided with a clamping channel 421, in which the blasting component 41 is installed.

[0087] In the above scheme, such as Figure 2 As shown, a mounting base 42 is provided at the lower end of the main beam assembly 20, and the mounting base 42 is detachably connected to the main beam assembly 20. The mounting base 42 has a hollow structure, and a clamping channel 421 is located in the middle of the mounting base 42. The diameter of the clamping channel 421 is adjustable, and one end of the explosive component 41 is inserted into the clamping channel 421. Through the mounting base 42, the explosive component 41 can be quickly connected to the lower end of the main beam assembly 20. When the explosive component 41 has various diameters, all can be inserted into the clamping channel 421, making this application applicable to various explosive components 41 for explosive treatment of different second cement lumps.

[0088] Furthermore, the length of either the first cantilever 311 or the second cantilever 312 is less than the radius of the cement silo 100.

[0089] In the above scheme, the length of the first cantilever 311 is set to be less than the radius of the cement silo 100, and the length of the second cantilever 312 is set to be less than the radius of the cement silo 100, so that the cantilever 31 can swing smoothly in the cement silo 100 and avoid getting stuck with the inner wall of the cement silo 100.

[0090] Furthermore, the first cantilever 311 and the second cantilever 312 are hollow structures, and the cross-sections of the first cantilever 311 and the second cantilever 312 are inverted triangles.

[0091] In the above scheme, such as Figure 3 , Figure 4 As shown, in this application, the first cantilever 311 and the second cantilever 312 are generally triangular prisms and are both hollow structures. The radial cross-sectional shape of the first cantilever 311 and the second cantilever 312 is an inverted triangle. Figure 3 As shown, the side of the first cantilever 311 and the second cantilever 312 facing the bottom of the cement silo 100 is an edge, while the side facing the top wall of the cement silo 100 is a plane. The advantage of this arrangement is that when the drive assembly drives the first cantilever 311 and the second cantilever 312 to swing, the side of the first cantilever 311 and the second cantilever 312 facing the top wall of the cement silo 100 is a plane, resulting in a large force-bearing area and making it less prone to bending under external forces. Furthermore, because the side of the first cantilever 311 and the second cantilever 312 facing the top wall of the cement silo 100 is a plane, such as... Figure 9 As shown, sensors for detecting the internal condition of the cement silo 100 can also be installed on this plane, and a fixing ring 94 can be installed on this plane to facilitate the fixing of the first traction rope 51 and the second traction rope 52 to the fixing ring 94 so as to pull the cantilever.

[0092] Furthermore, the cantilever 31 also includes a first reinforcing member 81 disposed in the first cantilever 311 and a second reinforcing member 82 disposed in the second cantilever 312; and the first reinforcing member 81 and the second reinforcing member 82 are disposed adjacent to each other.

[0093] In the above scheme, such as Figure 13 As shown, both the first cantilever 311 and the second cantilever 312 are hollow structures. When the first cantilever 311 and the second cantilever 312 are hinged together, they are prone to breakage when their connecting ends rotate relative to each other. Therefore, a first reinforcing member 81 is provided at the end where the first cantilever 311 connects to the second cantilever 312, and a second reinforcing member 82 is provided at the end where the second cantilever 312 connects to the first cantilever 311. This increases the strength of the two connecting ends through the reinforcing members, making them less prone to breakage and increasing their service life.

[0094] Furthermore, such as Figures 10-14 As shown, a wire hole 34 is formed between the inner wall of the first reinforcing member 81 and the inner wall of the first cantilever 311, and between the inner wall of the second reinforcing member 82 and the second cantilever 312.

[0095] In the above scheme, a first reinforcing member 81 is provided at the end where the first cantilever 311 connects to the second cantilever 312, and a second reinforcing member 82 is provided at the end where the second cantilever 312 connects to the first cantilever 311. This can strengthen the connection between the first cantilever 311 and the second cantilever 312. At the same time, it is also necessary to consider the need to arrange electrical connection wires in the first cantilever 311 and the second cantilever 312 to facilitate the control of each component by the whole device. Therefore, when the first reinforcing member 81 is arranged in the first cantilever 311, a wire hole 34 is reserved between it and the inner wall of the first cantilever 311. Similarly, when the first reinforcing member 82 is arranged in the second cantilever 312, a wire hole 34 is reserved between it and the inner wall of the second cantilever 312. The number and position of the wire holes on the adjacent end faces of the first cantilever 311 and the second cantilever 312 correspond to each other. This makes it easy for the electrical connection wires to pass through the wire hole 34 in the first cantilever 311 and enter the wire hole 34 in the second cantilever 312, and then connect to other components. Meanwhile, the wire-passing holes 34 provided in the first cantilever 311 and the second cantilever 312 not only facilitate the passage of electrical connection wires, but also protect the electrical connection wires, preventing them from being exposed on the outside of the first cantilever 311 and the second cantilever 312 and being damaged by cement, etc.; they also play a certain limiting role for the electrical connection wires, preventing multiple electrical connection wires from getting tangled in the first cantilever 311 and the second cantilever 312.

[0096] It should be noted that the number of threading holes 34 can be one, two, three, four, etc., and there is no restriction here.

[0097] Furthermore, such as Figures 9-14 As shown, one of the first cantilever 311 and the second cantilever 312 is provided with a protrusion 91, and the other is provided with a connecting seat 92 that mates with the protrusion 91. The protrusion 91 and the connecting seat 92 are hinged together.

[0098] In the above scheme, the first cantilever 311 and the second cantilever 312 are hinged together. Specifically, the hinged connection structure involves a protrusion 91 at one end of either the first cantilever 311 or the second cantilever 312, and a connecting seat 92 that mates with the protrusion 91 is provided on the adjacent end of the other cantilever. The two are hinged together by a pin 93. For example, the connecting seat 92 can be a U-shaped seat, or it could be a connecting block, etc., without limitation.

[0099] Furthermore, such as Figure 13 , Figure 14 As shown, both the first reinforcing member 81 and the second reinforcing member 82 include a reinforcing column 811 and a reinforcing plate 812. The reinforcing plate 812 is fixedly connected to the inner wall of the first cantilever 311 and the inner wall of the second cantilever 312, respectively. The reinforcing column 811 is installed in the reinforcing plate 812.

[0100] In the above scheme, the first reinforcing member 81 and the second reinforcing member 82 have the same structure, both including a reinforcing column 811 and a reinforcing plate 812. The reinforcing plate 812 is arranged along the direction away from the adjacent ends of the first cantilever 311 and the second cantilever 312. Multiple reinforcing plates 812 are provided, with adjacent pairs spaced apart. The reinforcing plates 812 are fixedly connected to the inner walls of the first cantilever 311 and the second cantilever 312, such as by adhesive or nuts. A through hole is provided in the middle of the reinforcing plate 812, through which the reinforcing column 811 can be installed and connected to the reinforcing plate 812, thereby strengthening the first cantilever 311 and the second cantilever 312 and increasing their strength.

[0101] At the same time, the reinforcing post 811 can also fix the lower end of the fixing ring 94 installed on the first cantilever 311 and the second cantilever 312 in the reinforcing post 811, and the reinforcing post 811 increases the firmness of the fixing ring 94 on the first cantilever 311 and the second cantilever 312.

[0102] Furthermore, such as Figure 1 As shown, the wall-cleaning assembly 30 also includes a driving component 33. One end of the driving component 33 is connected to the cantilever 31, and the other end is connected to the crushing component 32. The driving component 33 can drive the crushing component 32 to swing relative to the cantilever 31. By using the driving component 33, the cleaning device can control the swing of the crushing component 32 to remove the second cement clumps by controlling the driving component 33 alone. Once the main beam assembly 20 is adjusted to a suitable position, the cement clumps can be removed simply by adjusting the swing positions of the cantilever 31 and the crushing component 32, without needing to continuously adjust the height of the main beam assembly 20.

[0103] This application also provides an operating method for a cement silo cleaning device, which includes the following steps:

[0104] The positions of the first cement block and the second cement block in the cement silo 100 are obtained. The first cement block is a cement block in the cement of the cement silo 100, and the second cement block is a cement block on the inner wall of the cement silo 100. The positions of the first cement block and the second cement block can be obtained by sensors installed in the cement silo 100.

[0105] Based on the position of the first cement block, the length of the main beam assembly 20 is adjusted to move the blasting assembly 40 axially along the cement silo 100; the lifting assembly 10 is adjusted to drive the blasting assembly 40 to rotate circumferentially along the cement silo 100; the drive assembly is controlled to drive the main beam assembly 20 to swing the blasting assembly 40 radially along the cement silo 100; thereby enabling the blasting assembly 40 to reach the position of the first cement block and blast it. After the blasting assembly 40 blasts and clears the first cement block, the cement in the cement silo 100 can be smoothly discharged from the outlet. At this time, the second cement block, which was covered by cement on the inner wall of the cement silo 100, will also be exposed, facilitating the subsequent cleaning of the second cement block.

[0106] Based on the position of the second cement block, the lifting assembly 10 is adjusted to drive the wall cleaning assembly 30 to rotate circumferentially along the cement silo 100; the length of the main beam assembly 20 is adjusted to move the wall cleaning assembly 30 axially along the cement silo 100; thereby enabling the wall cleaning assembly 30 to reach the position of the second cement block and break it up.

[0107] In the above scheme, there is no order restriction for first using the blasting component 40 to blast the first cement block and then using the wall-cleaning component 30 to break the second cement block. The cleaning process can be controlled and started according to actual needs. For example, if there is no first cement block in the cement silo 100, the wall-cleaning component 30 can be used to break the second cement block first. The broken second cement block will fall into the cement in the cement silo 100 to form the first cement block, and then the blasting component 40 can be used to blast the first cement block.
