Description

Technical Field

[0001] The utility model relates to the technical field of mining equipment, in particular to a compacting device for slope surfaces. Background Art

[0002] As we all know, when coal is stored in a pile, it is very easy to spontaneously combust. In the relevant technology, measures such as spraying fire-proof extinguishing materials on the surface of the coal pile to isolate oxygen are usually taken to prevent coal spontaneous combustion. In order to improve the effect of the anti-spontaneous combustion spraying operation, the coal pile is usually leveled and compacted before spraying the fire-proof extinguishing materials.

[0003] In the prior art, slope treatment for embankment projects, concrete projects and pile foundation projects generally uses hydraulic tampers or slope rollers installed on the arm of an excavator to level and compact the slope. Due to the complex on-site environment of the coal yard, the different coal particle sizes in the coal yard, the large slope of the coal yard, the large slope fluctuation, and the large coverage area of ​​the coal yard, the arm length size of ordinary excavators is limited, the overall device of the slope roller occupies a large area, has a complex structure, and cannot efficiently change its own weight, and cannot meet the needs of coal pile slopes in different soft states. All of them are not suitable for leveling and compacting the coal pile slopes in the coal yard. Utility Model Content

By adjusting the weight of the compacting roller, it can be applied to the leveling and compacting of the slope surface of the coal pile under different working conditions, and the leveling and compacting effect of the slope surface of the coal pile is better. By adjusting the weight of the counterweight box, when the weight of the compacting roller is adjusted, the traction vehicle and the compacting roller can still be guaranteed to have a good balance. During the compaction operation, the traction vehicle will not roll over, and the weight of the compacting roller and the counterweight box can be adjusted without the need for additional measurement work, so that the weight of the compacting roller and the counterweight box can be adapted.

[0057] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0058] See also Figure 1-Figure 2 , the compaction device 200 for the slope 300 surface 301 includes a compaction roller assembly 100, a traction vehicle 201, a traction device 203 and a counterweight box 204. It should be noted that in the present application, the slope 300 surface 301 can be the slope 300 surface 301 of a coal pile in the coal storage field, or the slope 300 surface 301 of a soil pile, a concrete pile, etc. in the fields of embankment engineering, concrete engineering and pile foundation engineering. That is to say, the compaction device 200 for the slope 300 surface 301 of the embodiment of the present application can not only be used for the leveling and compaction of the slope 300 surface 301 of the coal pile, but also can be used for the leveling and compaction of the slope 300 surface 301 of the soil pile, the concrete pile, etc. In the following description of the present application, the compaction device 200 is used for the leveling and compaction of the slope 300 surface 301 of the coal pile as an example for exemplary description, but it can be understood that the present application is not limited to this.

[0059] The compaction roller assembly 100 includes a compaction roller 10 and a rotating shaft 20, the rotating shaft 20 is rotatably connected to the compaction roller 10, the traction vehicle 201 includes a vehicle body 2011 and wheels 2012, the wheels 2012 are rotatably connected to the vehicle body 2011, the wheels 2012 can be tracked wheels, that is, the traction vehicle 201 can be a tracked vehicle, and the traction device 203 is arranged on the vehicle body 2011, and the traction device 203 is connected to the rotating shaft 20 to drive the compaction roller 10 to roll up and down on the slope 300. For example, please refer to Figure 2 The traction device 203 may be a winding wire device. Specifically, the traction device 203 includes a driving motor 2031, a drum 2032 and a winding wire 2033. The winding wire 2033 is wound on the drum 2032. The free end of the winding wire 2033 is connected to the rotating shaft 20. The driving motor 2031 is connected to the drum 2032 to drive the drum 2032 to rotate, thereby driving the winding wire 2033 to be retracted and released, and then driving the compaction roller 10 to roll up and down on the slope 301.

[0060] Exemplarily, the winding strand 2033 may be a steel wire rope, which may make the winding strand 2033 have a higher structural strength and not easily break when driving the compaction roller 10. Of course, the present application is not limited thereto, and the winding strand 2033 may also be a nylon wire or the like.

[0061] Please continue reading Figure 2The drum 2032 may include two drum parts, namely a first drum part 20321 and a second drum part 20322, the winding wire 2033 may include two winding wires 2033, namely a first winding wire 20331 and a second winding wire 20332, the first winding wire 20331 is wound on the first drum part 20321, and the second winding wire 20332 is wound on the second drum part 20322, the free end of the first winding wire 20331 is connected to one axial end of the rotating shaft 20 (such as the first connecting shaft section 22 described below), and the free end of the second winding wire 20332 is connected to the other axial end of the rotating shaft 20 (such as the second connecting shaft section 23 described below). The driving motor 2031 drives the first drum portion 20321 and the second drum portion 20322 to rotate synchronously, so that the first coil 20331 and the second coil 20332 can be retracted and released synchronously, thereby driving the compacting roller 10 to roll up and down on the slope 301 .

[0062] By making the drum 2032 include a first drum portion 20321 and a second drum portion 20322, and the twisted wire 2033 includes a first twisted wire 20331 and a second twisted wire 20332, the first twisted wire 20331 and the second twisted wire 20332 are connected to and drive the compaction roller 10 at the same time, thereby making the connection stability of the twisted wire 2033 to the compaction roller 10 higher.

[0063] For further information, please refer to Figure 2 The winding wire 2033 device also includes a guide wheel 2034 for guiding the winding wire 2033 to be retracted and released. The guide wheel 2034 includes two guide wheels 20341 and a second guide wheel 20342. The first winding wire 20331 cooperates with the first guide wheel 20341 to guide the retraction and release direction of the first winding wire 20331. The second winding wire 20332 cooperates with the second guide wheel 20342 to guide the retraction and release direction of the second winding wire 20332.

[0064] Of course, the present application is not limited thereto. In some other embodiments, the drum 2032 may include only one drum portion, so that the winding wire 2033 includes only one winding wire 2033, and the guide wheel 2034 includes only one guide wheel 2034. In this way, the two axial ends of the rotating shaft 20 need to be connected to the same winding wire 2033. In this way, please refer to Figure 3 The compaction roller assembly 100 may further include a traction rigging 30, which includes a first rigging connection portion 31, a second rigging connection portion 32 and a third rigging connection portion 33. The third rigging connection portion 33 is located between the first rigging connection portion 31 and the second rigging connection portion 32. The first rigging connection portion 31 is connected to one axial end of the rotating shaft 20, the second rigging connection portion 32 is connected to the other axial end of the rotating shaft 20, and the third rigging connection portion 33 is connected to the free end of the winding wire 2033.

[0065] Please return to Figure 1 When the compacting device 200 for the slope 301 of the slope 300 is used for leveling and compacting the slope 301 of the coal pile, the traction vehicle 201 is located at the top of the slope, and the compacting roller 10 is located at the bottom of the slope. The driving motor 2031 controls the drum 2032 to rotate the lower winding strand 2033, and connects the winding strand 2033 with the compacting roller 10. The driving motor 2031 controls the drum 2032 to rotate in the opposite direction to wind up the winding strand 2033, thereby driving the compacting roller 10 to roll upward on the slope 301. When the compacting roller 10 rolls to the top of the slope, the motor 2031 can be driven again to rotate the lower winding strand 2033, thereby driving the compacting roller 10 to roll downward on the slope 301. When the compacting roller 10 rolls at the bottom of the slope, the motor 2031 can be driven in the opposite direction again to wind up the winding strand 2033, thereby driving the compacting roller 10 The compaction roller 10 rolls upward on the slope again. The number of times the compaction roller 10 rolls up and down on the slope 301 can be arbitrarily selected as needed. When the flatness and compaction degree of the area to be rolled on the slope 301 meet the requirements, the compaction roller 10 does not need to be rolled back and forth on the area. At this time, the compaction roller 10 is moved to the bottom of the slope, and the winding wire 2033 can be continued to be lowered to preset a certain displacement length. At this time, the compaction roller 10 can be moved to the bottom of the area to be rolled by the moving device 400, and the moving device 400 is removed. At the same time, the traction vehicle 201 is controlled to run to the required position according to the position of the compaction roller 10, and then the above-mentioned process of retracting and releasing the winding wire 2033 is repeated, so that the compaction roller 10 rolls up and down on the area to be rolled to level and compact the area. Among them, the moving device 400 can be arbitrarily selected as needed, and this application does not limit this.

[0066] It is understandable that different coal piles have different coal particle sizes and different softness, and the slope surface 301 has different concave and convex degrees and different slopes. In order to improve the leveling and compacting effect of the slope surface 301, it is necessary to select a compaction roller 10 of a specific specification and weight according to factors such as the coal particle size, the softness of the coal pile, and the slope size of the slope surface 301. In this way, it is necessary to match multiple models of compaction rollers 10, which not only increases the production cost, but also causes a large load on transportation. In order to solve this technical problem, a roller liquid storage chamber 101 is provided in the compaction roller 10, and liquid can be stored in the roller liquid storage chamber 101. By adjusting the weight of the liquid stored in the roller liquid storage chamber 101, the overall weight of the compaction roller 10 can be adjusted to be suitable for the leveling and compaction operations of the slope surface 301 of the slope 300 under different working conditions.

[0067] In addition, when the compacting device 200 is actually working, the tractor 201 is located at the top of the slope, and the compacting roller 10 is located on the slope surface 301 of the slope 300. If the weight of the tractor 201 is too large, the operating load of the tractor 201 will increase. If the weight of the tractor 201 is too small, the tractor 201 will roll over under the load of the compacting roller 10. Therefore, the weight of the tractor 201 and the weight of the compacting roller 10 should be matched, and the weight of the tractor 201 can be reduced without rolling over, thereby reducing the operating load of the tractor 201.

[0068] The tractor vehicle 201 is generally a large and heavy mechanical equipment. In practical applications, it is impossible to match tractor vehicles 201 of different specifications with compaction rollers 10 of different specifications. In order to solve this technical problem, the compaction device 200 further includes a counterweight box 204, which is arranged on the vehicle body 2011 and located on the side of the tractor device 203 away from the compaction roller 10. In this way, the weight of the counterweight box 204 can be changed to change the overall weight of the tractor vehicle 201, so that it can be better adapted to compaction rollers 10 of different weights.

[0069] It is understandable that when the weight of the compacting roller 10 changes, in order to better adapt to the weight of the compacting roller 10 so that the compacting device 200 obtains better balance, the weight of the counterweight box 204 must also be adjusted accordingly. In some embodiments, the compacting device 200 can match multiple counterweight boxes 204 of different specifications and weights for selection as needed in actual applications. However, this not only has high production costs, but also creates a large load for transportation. At the same time, in actual operations, the counterweight box 204 needs to be installed and disassembled multiple times, making the entire compaction operation process very cumbersome.

[0070] In order to solve this technical problem, a counterweight liquid storage chamber 2041 is provided in the counterweight box 204, and liquid can be stored in the counterweight liquid storage chamber 2041. By adjusting the weight of the liquid stored in the counterweight liquid storage chamber 2041, the overall weight of the counterweight box 204 can be adjusted to make the weight of the counterweight box 204 match the weight of the compaction roller 10.

[0071] Optionally, the liquid stored in the roller liquid storage chamber 101 and the counterweight liquid storage chamber 2041 may be water (e.g., firefighting water at a coal site), so that it is simple and convenient to obtain the required liquid in the roller liquid storage chamber 101 and the counterweight liquid storage chamber 2041. Of course, the present application is not limited thereto, and the liquid may also be salt water or other chemical liquids.

[0072] It can be understood that for different coal piles, the required weight of the compaction roller 10 is different. In actual operation, an empty compaction roller 10 and an empty counterweight box 204 are generally first used for a rolling test, that is, when the first rolling test is performed, no liquid is stored in the roller liquid storage chamber 101 and the counterweight liquid storage chamber 2041. At this time, the weight of the compaction roller 10 and the counterweight box 204 are both in the lightest state. After the rolling test, the indentation of the area rolled by the compaction roller 10 is detected to obtain the indentation detection depth Dc. If the indentation detection depth Dc is greater than or equal to the preset depth threshold Ds, it is said that the weight of the compaction roller 10 at this time can meet the compaction operation requirements, and there is no need to adjust the weight of the compaction roller 10 and the counterweight box 204; if the indentation detection depth Dc is less than the preset depth threshold Ds, it means that the weight of the compaction roller 10 at this time is too light and cannot meet the rolling requirements. If the indentation detection depth Dc is greater than or equal to the preset depth threshold Ds, it means that the weight of the compaction roller 10 at this time can meet the compaction operation requirements, and there is no need to adjust the weight of the compaction roller 10 and the counterweight box 204; if the indentation detection depth Dc is less than the preset depth threshold Ds, it means that the weight of the compaction roller 10 at this time is still relatively light and cannot meet the compaction requirements. It is necessary to continue to transport liquid into the roller liquid storage chamber 101 and the counterweight liquid storage chamber 2041, continue to increase the weight of the compaction roller 10 and the counterweight box 204, and perform the compaction test again, and repeat this process until the weight of the compaction roller 10 and the counterweight box 204 can meet the operation requirements.

[0073] The preset depth threshold Ds can be arbitrarily selected according to actual needs. For example, the preset depth threshold Ds ranges from 30 mm to 80 mm, that is, the preset depth threshold Ds can be greater than or equal to 30 mm and less than or equal to 80 mm. For example, the preset depth threshold Ds can be 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, 55 mm, 60 mm, 65 mm, 70 mm, 75 mm or 80 mm, etc. By setting the preset depth threshold Ds range to 30 mm to 80 mm, the compaction and leveling effect of the slope 301 is good.

[0074] It can be understood that during the above-mentioned rolling test process, when it is necessary to transport liquid toward the roller liquid storage chamber 101 and the counterweight liquid storage chamber 2041, in order to achieve quantitative transportation, in some embodiments, when transporting the liquid, it is necessary to use a flow monitoring device (such as a flow meter, etc.) to monitor the liquid transported to the roller liquid storage chamber 101 and the counterweight liquid storage chamber 2041. This not only makes the overall structural components of the compaction device 200 more, but also makes the operation more cumbersome during actual operation.

[0075] In order to solve the above technical problems, in some embodiments of the present application, please refer to Figure 4-Figure 7 A plurality of roller liquid storage cavities 101 are provided in the compacting roller 10, each of which has a roller liquid filling port 102, and a plurality of counterweight liquid storage cavities 2041 are provided in the counterweight box 204, each of which has a counterweight liquid filling port 2042, wherein the plurality of roller liquid storage cavities 101 and the plurality of counterweight liquid storage cavities 2041 correspond one to one.

[0076] That is to say, the compaction roller 10 has a plurality of roller liquid storage chambers 101, each roller liquid storage chamber 101 has a roller liquid injection port 102, and the roller liquid injection port 102 is used to transport liquid toward the corresponding roller liquid storage chamber 101. The compaction roller 10 also includes a roller switch member 102a for opening and closing the roller liquid injection port 102. When liquid needs to be transported toward the roller liquid storage chamber 101, the roller switch member 102a is opened to open the roller liquid injection port 102, and liquid can be transported toward the roller liquid storage chamber 101 through the roller liquid injection port 102. When the liquid is transported, the roller switch member 102a is closed to close the roller liquid injection port 102, and the rolling work can be carried out at this time.

[0077] The counterweight box 204 has a plurality of counterweight liquid storage chambers 2041, each counterweight liquid storage chamber 2041 has a counterweight liquid filling port 2042, and the counterweight liquid filling port 2042 is used to transport liquid toward the corresponding counterweight liquid storage chamber 2041. The compacting device 200 also includes a counterweight switch 2042a for opening or closing the counterweight liquid filling port 2042. When liquid needs to be transported toward the counterweight liquid storage chamber 2041, the counterweight switch 2042a is opened to open the counterweight liquid filling port 2042, and liquid can be transported toward the counterweight liquid storage chamber 2041 through the counterweight liquid filling port 2042. When the liquid is transported, the counterweight switch 2042a is closed to close the counterweight liquid filling port 2042.

[0078] The roller switch element 102a can be selected as needed. For example, the roller switch element 102a can be a control valve, such as a ball valve. In some other examples, see Figure 4 The roller switch member 102a can also be a sealing cover, which cooperates with the roller injection port 102 to block the roller injection port 102, thereby closing the roller injection port 102; the roller injection port 102 is opened by removing the sealing cover from the roller injection port 102.

[0079] Similarly, the counterweight switch element 2042a can be selected as needed. For example, see Figure 2, the counterweight switch element 2042a can be a control valve, such as a ball valve, etc. In some other embodiments, the counterweight switch element 2042a can also be a sealing cover, and the sealing cover cooperates with the counterweight liquid injection port 2042 to block the counterweight liquid injection port 2042, thereby making the counterweight liquid injection port 2042 in a closed state; by removing the sealing cover from the counterweight liquid injection port 2042, the counterweight liquid injection port 2042 is opened, thereby making the counterweight liquid injection port 2042 in an open state.

[0080] It should be noted that in the present application, "one-to-one correspondence between multiple roller liquid storage chambers 101 and multiple counterweight liquid storage chambers 2041" means that the number of roller liquid storage chambers 101 possessed by the compacting roller 10 is equal to the number of counterweight liquid storage chambers 2041 possessed by the counterweight box 204, and one roller liquid storage chamber 101 corresponds to one counterweight liquid storage chamber 2041, and there is also a specific corresponding relationship between the volumes of the corresponding roller liquid storage chambers 101 and the counterweight liquid storage chambers 2041. In the corresponding roller liquid storage chambers 101 and the counterweight liquid storage chambers 2041, if the roller liquid storage chamber 101 is full of liquid, the counterweight liquid storage chamber 2041 must also be full of liquid, thereby ensuring that the traction vehicle 201 and the compacting roller 10 have a better balance at this time. It can be understood that, in the roller liquid storage chamber 101 and the counterweight liquid storage chamber 2041 that correspond to each other, if no liquid is stored in the roller liquid storage chamber 101 , no liquid is stored in the counterweight liquid storage chamber 2041 either.

[0081] When the compaction roller 10 and the counterweight box 204 need to be weighted, it is only necessary to fill the corresponding roller liquid storage chamber 101 and the counterweight liquid storage chamber 2041 with liquid to ensure that the traction vehicle 201 and the compaction roller 10 have good stability while increasing the weight.

[0082] It can be understood that the number of roller liquid storage chambers 101 of the compacting roller 10 and the number of counterweight liquid storage chambers 2041 of the counterweight box 204, as well as the volumes of the roller liquid storage chambers 101 and the counterweight liquid storage chambers 2041 corresponding to each other, can be set according to actual needs and experimental tests, so that they can be suitable for the compaction and leveling of the slope surface 301 of the coal pile slope 300 under different working conditions. In this way, the weight of the compacting roller 10 can be quantitatively adjusted by controlling the number of roller liquid storage chambers 101 storing liquid, and the storage of liquid in the counterweight liquid storage chamber 2041 corresponding to the roller liquid storage chamber 101 can ensure that the traction vehicle 201 and the compacting roller 10 have a good balance. Therefore, when it is necessary to adjust the weight of the compaction roller 10 and the counterweight box 204, there is no need to use an additional flow monitoring device (such as a flow meter, etc.) to monitor the liquid delivered to the roller liquid storage chamber 101 and the counterweight liquid storage chamber 2041, which not only simplifies the overall structure of the compaction device 200, but also makes the compaction operation process simpler.

[0083] In summary, according to the compaction device 200 for the slope surface 301 of the slope 300 of the embodiment of the utility model, by setting the roller liquid storage chamber 101 in the compaction roller 10, the weight of the compaction roller 10 can be adjusted by conveying liquid into the roller liquid storage chamber 101, and thus the compaction device 200 is suitable for leveling and compacting the slope surface 301 of the coal pile slope 300 in different working conditions, and the leveling and compaction effect of the slope surface 301 of the coal pile slope 300 is better. By setting the counterweight liquid storage chamber 2041 in the counterweight box 204, the weight of the counterweight box 204 can be adjusted by conveying liquid into the counterweight liquid storage chamber 2041, so that when the weight of the compaction roller 10 is adjusted, the traction vehicle 201 and the compaction roller 10 can still be ensured to have a good balance, and the traction vehicle 201 will not roll over during the compaction operation. In addition, by making the compaction roller 10 include multiple roller liquid storage chambers 101, and the counterweight box 204 include multiple counterweight liquid storage chambers 2041, the multiple roller liquid storage chambers 101 and the multiple counterweight liquid storage chambers 2041 correspond one to one. In this way, the weight of the compaction roller 10 and the counterweight box 204 can be adjusted without the aid of additional measuring tools, thereby achieving quantitative adjustment of the weight of the compaction roller 10 and making the weight of the compaction roller 10 and the weight of the counterweight box 204 match each other, thereby ensuring a good balance between the traction vehicle 201 and the compaction roller 10.

[0084] In some embodiments of this application, please refer to Figure 4-Figure 6, multiple roller liquid storage chambers 101 are sequentially arranged from the inside to the outside, and the roller liquid injection port 102 is arranged at the axial end of the corresponding roller liquid storage chamber 101. By making multiple roller liquid storage chambers 101 sequentially arranged from the inside to the outside, the overall balance of the compaction roller 10 is better, and the leveling and compaction effect of the slope 300 is better during the compaction operation. In addition, by making the roller liquid injection port 102 be arranged at the axial end of the corresponding roller liquid storage chamber 101, when the compaction roller 10 rolls on the slope surface 301 of the slope 300, the roller switch member 102a arranged at the roller liquid injection port 102 will not contact the slope surface 301, thereby not only ensuring the flatness of the slope surface 301, but also preventing the roller switch member 102a from loosening or being damaged.

[0085] Optionally, see Figure 4 Each roller liquid storage cavity 101 may include a plurality of roller liquid injection ports 102 , and the plurality of roller liquid storage cavities 101 are spaced apart from each other in the circumferential direction.

[0086] In some embodiments of this application, please refer to Figure 5 The rotating shaft 20 includes a penetration shaft section 21 located in the compacting roller 10, a first connecting shaft section 22 and a second connecting shaft section 23 located outside the compacting roller 10. A penetration shaft cavity 103 is provided in the compacting roller 10. The penetration shaft section 21 is located in the penetration shaft cavity 103. The innermost roller liquid storage cavity 101 among the plurality of roller liquid storage cavities 101 is covered with the penetration shaft cavity 103 and is not connected with the penetration shaft cavity 103. By providing the penetration shaft cavity 103 not connected with the roller liquid storage cavity 101 in the compacting roller 10, the penetration shaft cavity 103 is used to accommodate the penetration shaft section 21 of the rotating shaft 20, so that the sealing performance of the roller liquid storage cavity 101 can be improved.

[0087] In some optional embodiments of this application, please continue to refer to Figure 5The compaction roller 10 includes an outer ring tube 11, an inner ring tube 12, at least one separating ring tube 17, a first end plate 13 and a second end plate 14. The inner ring tube 12 is sleeved in the outer ring tube 11 at intervals. The separating ring tube 17 is sleeved between the outer ring tube 11 and the inner ring tube 12 at intervals. When the separating ring tube 17 includes multiple separating ring tubes, the multiple separating ring tubes 17 are sleeved in sequence at intervals in the direction from the inner ring tube 12 to the outer ring tube 11. The first end plate 13 and the second end plate 14 are respectively arranged at the axial ends of the inner ring tube 12, and are connected to the inner ring tube 12, the separating ring tube 17 and the outer ring tube 11. The first connecting shaft section 22 is located at On the side of the first end plate 13 away from the second end plate 14, the second connecting shaft section 23 is located on the side of the second end plate 14 away from the first end plate 13, the first end plate 13, the second end plate 14 and the inner ring tube 12 define a through-shaft cavity 103, the first end plate 13, the second end plate 14, the inner ring tube 12 and the outer ring tube 11 define a roller liquid storage cavity assembly 101a, the roller liquid storage cavity assembly 101a is divided by at least one separation ring tube 17 to form a plurality of roller liquid storage cavities 101, and the roller liquid injection port 102 is provided on the portion of the first end plate 13 located between the inner ring tube 12 and the outer ring tube 11. In this way, the internal structure of the compaction roller 10 is simple, and it is convenient for production and manufacturing.

[0088] In other embodiments of the present application, please refer to Figure 6 The inserted shaft segment 21 includes a first inserted shaft segment 211 and a second inserted shaft segment 212 spaced apart from each other, the inserted shaft cavity 103 includes a first inserted shaft cavity 1031 and a second inserted shaft cavity 1032 spaced apart from each other, the first inserted shaft segment 211 is accommodated in the first inserted shaft cavity 1031, the second inserted shaft segment 212 is accommodated in the second inserted shaft cavity 1032, the first inserted shaft segment 211 is connected to the first connecting shaft segment 22, the second inserted shaft segment 212 is connected to the second connecting shaft segment 23, the inner ring tube 12 includes a first inner ring tube 121 and a second inner ring tube 122 spaced apart from each other, one axial end of the first inner ring tube 121 is connected to the first end plate 13 The first inner ring tube 121 is connected to the second end plate 14, the first inner end plate 15 is provided at the other axial end of the first inner ring tube 121, and the first end plate 13, the first inner ring tube 121 and the first inner end plate 15 define a first shaft-penetrating cavity 1031, the second inner ring tube 122 is connected to the second end plate 14 at one axial end, the second inner ring tube 122 is provided with a second inner end plate 16 at the other axial end, and the second end plate 14, the second inner ring tube 122 and the second inner end plate 16 define a second shaft-penetrating cavity 1032, and the outer ring tube 11, the inner ring tube 12, the first end plate 13, the second end plate 14, the first inner end plate 15 and the second inner end plate 16 define a roller liquid storage cavity assembly 101a. In this way, the volume of the roller liquid storage cavity assembly 101a can be increased under the premise that the overall volume of the compaction roller 10 remains unchanged, thereby expanding the weight that can be allocated by the compaction roller 10.

[0089] In some embodiments of this application, please refer to Figure 4-Figure 6 The outer ring tube 11 includes a main body ring portion 111 and a first extension ring portion 112 which are connected axially. One axial end of the first extension ring portion 112 is connected to the main body ring portion 111, and the other axial end of the first extension ring portion 112 extends in a direction away from the first end plate 13. A roller liquid storage chamber assembly 101a is defined between the first end plate 13, the second end plate 14, the inner ring tube 12 and the main body ring portion 111. A protective chamber 104 is defined between the first extension ring portion 112 and the first end plate 13. The first connecting shaft section 22 is accommodated in the protective chamber 104, and the roller switch member 102a at the above-mentioned roller injection port 102 can also be accommodated in the protective chamber 104.

[0090] In this way, the first extension ring portion 112 can protect the rotating shaft 20 and the roller switch member 102a, prevent the protruding hard objects on the slope 301 from damaging the rotating shaft 20 and the roller switch member 102a, and also prevent the rotating shaft 20 and the roller switch member 102a from scratching the staff. In addition, by providing the first extension ring portion 112, the length of the rotating shaft 20 can be reduced while protecting the rolling area of ​​the compaction roller 10, thereby not only reducing the production cost, but also improving the structural strength of the rotating shaft 20.

[0091] Likewise, see Figure 5-Figure 6 The outer ring tube 11 may further include a second extension ring portion 113, which is connected to an end of the main ring portion 111 away from the first extension ring portion 112. The structure and function of the second extension ring portion 113 are similar to those of the first extension ring portion 112, and are not described in detail here.

[0092] In some embodiments of this application, please refer to Figure 4-Figure 6 , the roller liquid storage chamber assembly 101a includes a first roller liquid storage chamber 1011, a second roller liquid storage chamber 1012 and a third roller liquid storage chamber 1013, and the first roller liquid storage chamber 1011, the second roller liquid storage chamber 1012 and the third roller liquid storage chamber 1013 are sequentially arranged from the inside to the outside. In other words, the compaction roller 10 has three roller liquid storage chambers 101, and the three roller liquid storage chambers 101 are respectively the first roller liquid storage chamber 1011, the second roller liquid storage chamber 1012 and the third roller liquid storage chamber 1013 sequentially arranged from the inside to the outside. By making the number of roller liquid storage chambers 101 of the compaction roller 10 three, the compaction operation requirements of the slope 301 of the coal pile slope 300 under different working conditions can be met, and the overall structure of the compaction roller 10 is simple and easy to manufacture.

[0093] Of course, the present application is not limited thereto. In some other embodiments, the number of roller liquid storage cavities 101 of the compacting roller 10 can also be two, four, five or six.

[0094] For further information, please refer to Figure 5-Figure 6 The separation ring tube 17 includes a first separation ring tube 171 and a second separation ring tube 172. The inner ring tube 12, the first separation ring tube 171, the second separation ring tube 172 and the outer ring tube 11 are sequentially spaced from the inside to the outside. The first roller liquid storage chamber 1011 is formed between the inner ring tube 12 and the first separation ring tube 171, the second roller liquid storage chamber 1012 is formed between the first separation ring tube 171 and the second separation ring tube 172, and the third roller liquid storage chamber 1013 is formed between the second separation ring tube 172 and the outer ring tube 11. The compaction roller 10 has a simple structure and is easy to manufacture.

[0095] For further information, see Figure 7 , multiple counterweight liquid storage chambers 2041 are stacked from bottom to top. By stacking multiple counterweight liquid storage chambers 2041 from bottom to top, the overall structure of the counterweight box 204 is simple and convenient for production and manufacturing. Of course, the present application is not limited to this. In some examples, multiple counterweight liquid storage chambers 2041 can also be arranged in sequence along the left-right direction or the front-back direction; in other examples, multiple counterweight liquid storage chambers 2041 can also be arranged in sequence from inside to outside.

[0096] For further information, please refer to Figure 7 The counterweight box 204 includes a box body 2043 and at least one partition plate 2044. The box body 2043 defines a counterweight liquid storage chamber assembly 2041a. At least one partition plate 2044 is disposed in the counterweight liquid storage chamber assembly 2041a to separate the counterweight liquid storage chamber assembly 2041a into a plurality of counterweight liquid storage chambers 2041. The overall structure of the counterweight box 204 is simple and convenient for production and processing.

[0097] For further information, please refer to Figure 7The counterweight liquid storage chamber assembly 2041a includes a first counterweight liquid storage chamber 20411, a second counterweight liquid storage chamber 20412 and a third counterweight liquid storage chamber 20413 stacked from bottom to top, the partition plate 2044 includes a first partition plate 20441 and a second partition plate 20442 spaced above the first partition plate 20441, the first counterweight liquid storage chamber 20411 is formed between the bottom wall 20431 of the box body 2043 and the first partition plate 20441, the second counterweight liquid storage chamber 20412 is formed between the first partition plate 20441 and the second partition plate 20442, and the third counterweight liquid storage chamber 20413 is formed between the second partition plate 20442 and the top wall 20432 of the box body 2043. That is to say, the counterweight box 204 also has three counterweight liquid storage chambers 2041, which correspond one-to-one to the above-mentioned three roller liquid storage chambers 101. Specifically, the first counterweight liquid storage chamber 20411 corresponds to the above-mentioned first roller liquid storage chamber 1011. When the first roller liquid storage chamber 1011 is full of liquid, the first counterweight liquid storage chamber 20411 must also be filled with liquid; the second counterweight liquid storage chamber 20412 corresponds to the above-mentioned second roller liquid storage chamber 1012. When the second roller liquid storage chamber 1012 is full of liquid, the second counterweight liquid storage chamber 20412 must also be filled with liquid; the third counterweight liquid storage chamber 20413 corresponds to the above-mentioned third roller liquid storage chamber 1013. When the third roller liquid storage chamber 1013 is full of liquid, the third counterweight liquid storage chamber 20413 must also be filled with liquid.

[0098] It can be understood that the number of the counterweight liquid storage chambers 2041 of the counterweight box 204 is not limited to three, and the number of the counterweight liquid storage chambers 2041 should be equal to the number of the roller liquid storage chambers 101.

[0099] In some embodiments of this application, please refer to Figure 5-Figure 6 The compacting device 200 also includes a first connecting member 40 and a second connecting member 50. The first connecting member 40 includes a first connecting segment 41, a second connecting segment 42 and a third connecting segment 43 connected in sequence. The end of the first connecting segment 41 away from the second connecting segment 42 is connected to the first connecting shaft segment 22. The end of the third connecting segment 43 away from the second connecting segment 42 is suitable for connecting the traction device 203 (such as connecting the free end of the winding strand 2033 mentioned above). The second connecting segment 42 is directed toward the first connecting segment 41 in a direction away from the first connecting segment 41. Extending in the direction away from the first end plate 13; the second connecting member 50 includes a fourth connecting segment 51, a fifth connecting segment 52 and a sixth connecting segment 53 connected in sequence, an end of the fourth connecting segment 51 away from the fifth connecting segment 52 is connected to the second connecting shaft segment 23, and an end of the sixth connecting segment 53 away from the fifth connecting segment 52 is suitable for connecting to the traction device 203 (such as connecting the free end of the coiled wire 2033 mentioned above), wherein the fifth connecting segment 52 extends in the direction away from the fourth connecting segment 51 toward the direction away from the second end plate 14.

[0100] By setting the above-mentioned first connecting member 40 and second connecting member 50, the first connecting shaft segment 22 can be connected to the traction device 203 through the first connecting member 40, and the second connecting shaft segment 23 can be connected to the traction device 203 through the second connecting member 50, thereby making the connection between the first connecting shaft segment 22 and the traction device 203, and the connection between the second connecting shaft segment 23 and the traction device 203 more flexible.

[0101] In addition, the second connecting section 42 of the first connecting member 40 extends in a direction away from the first connecting section 41 toward a direction away from the first end plate 13, and the fifth connecting section 52 of the second connecting member 50 extends in a direction away from the fourth connecting section 51 toward a direction away from the second end plate 14. In this way, the first connecting member 40 and the second connecting member 50 both form a bending structure, which can avoid interference between the first connecting member 40, the second connecting member 50 and the compacting roller 10 when the compacting roller 10 rolls.

[0102] In addition, it can be understood that in actual operation, the compaction roller 10 will not only rotate relative to the rotating shaft 20, but also have a certain degree of shaking in its axial direction. By forming a bending structure between the first connecting member 40 and the second connecting member 50, the first connecting member 40 and the second connecting member 50 have a movable margin in the axial direction of the compaction roller 10, thereby improving the structural strength of the first connecting member 40 and the second connecting member 50 and avoiding the first connecting member 40 and the second connecting member 50 from breaking.

[0103] For further information, please refer to Figure 5-Figure 6 The compacting device 200 further includes a third connecting member 60, which extends along the axial direction of the compacting roller 10, one end of the third connecting member 60 is connected to the third connecting section 43, and the other end of the third connecting member 60 is connected to the sixth connecting section 53. By providing the third connecting member 60, the first connecting member 40 and the second connecting member 50 can be connected together, and when the compacting roller 10 is working, the overall rolling balance of the compacting roller 10 is better.

[0104] like Figure 2 As shown in , the compacting device 200 further includes a power generation device 205, which is arranged on the vehicle body 2011. The power generation device 205 may be a diesel power generation device, a gasoline power generation device, a solar power generation device or a natural gas power generation device. By arranging the power generation device 205, power can be supplied to the traction device 203. The control device 202 is electrically connected to the power generation device 205 and the traction device 203, and is used to control the power generation of the power generation device 205 and the operation of the traction device 203.

[0105] In some embodiments of the present application, the traction vehicle 201 is connected to the compaction roller 10 through a double-leg chain, so that the compaction roller 10 can be towed to the area to be operated by the traction vehicle 201. After the compaction roller 10 is towed to the area to be operated, the double-leg chain is removed, and the traction vehicle 201 and the compaction roller 10 are separated. At this time, the traction vehicle 201 can run to the area to be operated at the top of the slope. The traction vehicle 201 is connected to the compaction roller 10 through a double-leg chain, so that the connection and separation operations between the compaction roller 10 and the traction vehicle 201 are simple, convenient, and labor-saving.

[0106] The compaction device 200 of the present application can use wireless remote control to implement various functions. Construction personnel can control the equipment remotely to avoid personal injury to construction personnel due to improper operation of the equipment during the construction process. At the same time, the control of the equipment is more convenient and quick. For example, the compaction device 200 includes a remote control connected to the control device 202 by radio. The operation and travel direction of the traction vehicle 201 can be controlled by controlling the remote control, so that the traction vehicle 201 can be controlled by the remote control to move to the compaction roller 10 or the operation area at the top of the slope. The traction device 203 can also be controlled by the remote control to drive the compaction roller 10 to roll on the slope 301.
