[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.

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 compacting device 200 for the slope 300 surface 301 includes a compacting roller assembly 100, a traction vehicle 201 and a traction device 203. 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 compacting 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 compacting 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 30, the rotating shaft 30 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 2012, 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 30 to drive the compaction roller 10 to roll up and down on the slope 301 of 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 30. 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 30 (such as the first connecting shaft section 32 described below), and the free end of the second winding wire 20332 is connected to the other axial end of the rotating shaft 30 (such as the second connecting shaft section 33 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 30 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 80, which includes a first rigging connection portion 81, a second rigging connection portion 82 and a third rigging connection portion 83. The third rigging connection portion 83 is located between the first rigging connection portion 81 and the second rigging connection portion 82. The first rigging connection portion 81 is connected to one axial end of the rotating shaft 30, the second rigging connection portion 82 is connected to the other axial end of the rotating shaft 30, and the third rigging connection portion 83 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 softness, and the slope 301 has different degrees of unevenness and slopes. In order to improve the flatness and compaction effect of the slope 301, it is necessary to select a compaction roller 10 of a specific specification and weight based on factors such as the coal particle size, the softness of the coal pile, and the slope of the slope 301. In this way, it is necessary to match multiple models of compaction rollers 10, which not only increases the production cost, but also creates a heavy load on transportation.

[0067] To solve the above technical problems, please refer to Figure 4-Figure 6The present application discloses a compaction roller assembly 100, which includes a compaction roller 10, an infusion tube 20 and a rotating shaft 30. The rotating shaft 30 is rotatably connected to the compaction roller 10. A liquid storage chamber 101 is defined in the compaction roller 10. The compaction roller 10 is provided with a liquid injection port 102, which is connected to the liquid storage chamber 101. The liquid injection port 102 has an open state and a closed state. An opening and closing member 60 for opening and closing the liquid injection port 102 can be provided at the liquid injection port 102. When the opening and closing member 60 opens the liquid injection port 102, the liquid injection port 102 is in an open state. When the opening and closing member 60 closes the liquid injection port 102, the liquid injection port 102 is in a closed state.

[0068] It should be noted that the opening and closing member 60 can be selected as needed. For example, the opening and closing member 60 can be a control valve, such as a ball valve. Figure 4 The opening and closing member 60 can also be a sealing cover, which cooperates with the liquid injection port 102 to block the liquid injection port 102, thereby making the liquid injection port 102 in a closed state; the sealing cover is removed from the liquid injection port 102 to open the liquid injection port 102, thereby making the liquid injection port 102 in an open state. The infusion tube 20 has a first port 21 and a second port 22, the second port 22 is suitable for connecting to a liquid source, and when the liquid injection port 102 is in an open state, the first port 21 is suitable for communicating with the liquid injection port 102.

[0069] The liquid infusion tube 20 is used to transport liquid into the liquid storage chamber 101. For example, the liquid can be water, and the second port 22 is suitable for connecting to a water source, such as a fire-fighting water source at a coal site, so that it is simple and convenient to obtain the required liquid in the liquid storage chamber 101. Of course, the present application is not limited thereto, and the liquid can also be salt water or other chemical liquids.

[0070] When the liquid injection port 102 is in an open state, liquid can be delivered to the liquid storage chamber 101 through the liquid delivery pipe 20 to increase the rolling weight of the compaction roller 10. In practical applications, the amount of liquid delivered to the liquid storage chamber 101 can be determined according to factors such as the size of coal particles, the softness of the coal pile, and the slope of the slope 301. It can be understood that after the liquid delivery is completed, the liquid delivery pipe 20 is separated from the liquid injection port 102, and then the opening and closing member 60 is used to close the liquid injection port 102. At this time, the compaction roller 10 can be used for the compaction operation of the slope 301.

[0071] The first port 21 of the infusion tube 20 and the injection port 102 may be plug-connected, so that the infusion tube 20 can be more convenient to disassemble and assemble. Figure 4As shown in the figure, the first port 21 of the infusion tube 20 is directly inserted into the injection port 102, thereby realizing the connection between the first port 21 and the injection port 102; of course, the present application is not limited to this. In some other embodiments, the first port 21 of the infusion tube 20 can also be covered on the injection port 102.

[0072] During the compaction operation, liquid may not be delivered into the liquid storage chamber 101 first, that is, an empty compaction roller 10 is first used to perform a rolling test on the slope surface 301. According to the depth of the indentation on the slope surface 301, the compaction roller 10 is weighted, that is, the liquid injection port 102 is opened, and the liquid is quantitatively delivered into the liquid storage chamber 101 through the infusion tube 20. Different working conditions can be tested multiple times until the indentation depth meets the construction requirements.

[0073] It is understandable that when the weight of the compacting roller 10 needs to be increased, liquid can be transported into the liquid storage chamber 101 through the liquid infusion tube 20; when the weight of the compacting roller 10 needs to be reduced, the liquid injection port 102 can be directly opened, and the water in the compacting roller 10 can flow out through the liquid injection port 102, thereby reducing the weight of the compacting roller 10. Of course, a discharge port for discharging the liquid in the liquid storage chamber 101 can also be provided separately, the liquid injection port 102 is only used to add water to the liquid storage chamber 101, and the discharge port is only used to discharge the liquid in the liquid storage chamber 101. By providing the liquid injection port 102 and the discharge port, the structure and position of the liquid injection port 102 and the discharge port can be flexibly selected as needed, so that the effects of water injection and drainage are better.

[0074] In some embodiments, the compaction roller 10 may also include a discharge pipe and a discharge pump. When the liquid in the liquid storage chamber 101 needs to be discharged, the injection port 102 can be opened, the discharge pipe can be inserted into the liquid storage chamber 101, and the liquid in the liquid storage chamber 101 can be pumped out by the discharge pump.

[0075] In the above-mentioned process of water injection and drainage, there is no need to move the compacting roller 10, which is convenient and labor-saving to operate.

[0076] In summary, according to the compaction roller assembly 100 of the embodiment of the utility model, by setting the liquid storage chamber 101 in the compaction roller 10, the weight of the compaction roller 10 can be adjusted by conveying and discharging liquid into the liquid storage chamber 101, so as to be applicable to the leveling and compaction of the slope surface 301 of the coal pile slope 300 under different working conditions, and the leveling and compaction effect of the slope surface 301 of the coal pile slope 300 is better. In addition, the compaction roller assembly 100 has a simple structure, and the weight adjustment operation of the compaction roller 10 is convenient.

[0077] In some embodiments of the application, see Figure 4-Figure 5The compaction roller assembly 100 further includes a measuring device 40, which is disposed on the infusion tube 20 to measure the flow rate of the liquid delivered to the liquid storage chamber 101 through the infusion tube 20. Exemplarily, the measuring device 40 may be a water meter or a flow meter. By arranging the measuring device 40 on the infusion tube 20, the flow rate of the liquid delivered to the liquid storage chamber 101 through the infusion tube 20 may be measured, and then the weight of the liquid stored in the liquid storage chamber 101 may be obtained, thereby facilitating the control of the counterweight of the compaction roller 10.

[0078] For further information, see Figure 4-Figure 5 The compaction roller assembly 100 further includes a switch member 50, which is disposed on the infusion tube 20 to control the circulation of the liquid in the infusion tube 20, and the switch member 50 is located on the upstream side of the measuring device 40. It should be noted that the "upstream side" described in the present application is based on the direction of the liquid flow in the infusion tube 20. By locating the switch member 50 on the upstream side of the measuring device 40, when the switch member 50 is in an open state, the fluid in the infusion tube 20 can pass through the switch member 50 and the measuring device 40 in sequence, and then enter the liquid storage chamber 101; when the switch member 50 is in a closed state, the fluid in the infusion tube 20 is cut off at the position of the switch member 50, and the fluid can no longer pass through the infusion tube 20 into the liquid storage chamber 101. When the compaction roller 10 is weighted, the flow rate measured by the measuring device 40 can be observed. When the measured flow rate value meets the requirement, the switch 50 is closed to cut off the fluid in the infusion tube 20, and then the infusion tube 20 is separated from the injection port 102, and the opening and closing member 60 closes the injection port 102.

The second connecting shaft section 33 is located on the side of the second end plate 14 away from the first end plate 13. A through-shaft cavity 103 is defined between the first end plate 13, the second end plate 14 and the inner ring 12. A liquid storage cavity 101 is defined between the first end plate 13, the second end plate 14, the inner ring 12 and the outer ring 11. The liquid injection port 102 is arranged on the portion of the first end plate 13 located between the inner ring 12 and the outer ring 11. In this way, the compaction roller 10 has a simple internal structure and is convenient for production and manufacturing.

[0081] Please return to Figure 4-Figure 5 The liquid injection port 102 is provided on the first end plate 13, and the liquid injection port 102 may include a plurality of liquid injection ports 102, which may be spaced apart and distributed along the circumferential direction. By providing a plurality of liquid injection ports 102, when discharging the liquid in the liquid storage chamber 101, the plurality of liquid injection ports 102 may all be opened, thereby improving the discharge efficiency; of course, only the liquid injection port 102 closest to the ground may be opened, which may make it easier for the liquid in the liquid storage chamber 101 to flow out. For example, please refer to Figure 4 , there may be four injection ports 102. Of course, the present application is not limited thereto, and the number of injection ports 102 may be arbitrarily selected as required. For example, there may be one, two, three, five or more injection ports 102.

[0082] In addition, it should be noted that the injection port 102 of the present application can also be set on the second end plate 14, or when the injection port 102 includes multiple ones, a part of the multiple injection ports 102 are set on the first end plate 13, and another part of the multiple injection ports 102 are set on the second end plate 14.

[0083] In other embodiments of the present application, please refer to Figure 7The insertion shaft segment 31 includes a first insertion shaft segment 311 and a second insertion shaft segment 312 spaced apart from each other, the insertion shaft cavity 103 includes a first insertion shaft cavity 1031 and a second insertion shaft cavity 1032 spaced apart from each other, the first insertion shaft segment 311 is accommodated in the first insertion shaft cavity 1031, the second insertion shaft segment 312 is accommodated in the second insertion shaft cavity 1032, the first insertion shaft segment 311 is connected to the first connecting shaft segment 32, the second penetration shaft segment 312 is connected to the second connecting shaft segment 33, the inner ring 12 includes a first inner ring 121 and a second inner ring 122 spaced apart from each other, one axial end of the first inner ring 121 is connected to the first inner ring 122, and the inner ring 122 is connected to the first inner ring 122. The first inner ring 121 is connected to the second end plate 13, and the first inner end plate 15 is provided at the other axial end of the first inner ring 121. A first through-shaft cavity 1031 is defined between the first end plate 13, the first inner ring 121 and the first inner end plate 15. An axial end of the second inner ring 122 is connected to the second end plate 14, and a second inner end plate 16 is provided at the other axial end of the second inner ring 122. A second through-shaft cavity 1032 is defined between the second end plate 14, the second inner ring 122 and the second inner end plate 16. A liquid storage cavity 101 is defined between the outer ring 11, the inner ring 12, the first end plate 13, the second end plate 14, the first inner end plate 15 and the second inner end plate 16. In this way, the volume of the liquid storage cavity 101 can be increased without changing the overall volume of the compacting device 200, thereby increasing the weight that can be allocated by the compacting roller 10.

[0084] In some embodiments of this application, please refer to Figure 4-Figure 7 The outer ring 11 includes a main body ring portion 111 and a first extension ring portion 112 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 liquid storage chamber 101 is defined between the first end plate 13, the second end plate 14, the inner ring 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 segment 32 is accommodated in the protective chamber 104, and the opening and closing member 60 at the above-mentioned liquid injection port 102 can also be accommodated in the protective chamber 104.

[0085] In this way, the first extension ring portion 112 can protect the rotating shaft 30 and the opening and closing member 60, prevent the protruding hard objects on the slope 301 from damaging the rotating shaft 30 and the opening and closing member 60, and also prevent the rotating shaft 30 and the opening and closing member 60 from scratching the staff. In addition, by providing the first extension ring portion 112, the length of the rotating shaft 30 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 30.

[0086] Likewise, see Figure 6-Figure 7The outer ring 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 herein.

[0087] In some embodiments of this application, please refer to Figure 4-Figure 7 The compaction roller 10 further includes a connection assembly 70, the connection assembly 70 includes a first connection member 71 and a second connection member 72, the first connection member 71 includes a first connection segment 711, a second connection segment 712 and a third connection segment 713 connected in sequence, the end of the first connection segment 711 away from the second connection segment 712 is connected to the first connection shaft segment 32, the end of the third connection segment 713 away from the second connection segment 712 is suitable for connecting the traction device 203 (such as connecting the free end of the winding strand 2033 mentioned above), wherein the second connection segment 712 is away from the first connection segment 71 1 extends in the direction away from the first end plate 13; the second connecting member 72 includes a fourth connecting segment 721, a fifth connecting segment 722 and a sixth connecting segment 723 connected in sequence, an end of the fourth connecting segment 721 away from the fifth connecting segment 722 is connected to the second connecting shaft segment 33, and an end of the sixth connecting segment 723 away from the fifth connecting segment 722 is suitable for connecting to the traction device 203 (such as connecting to the free end of the coiled wire 2033 mentioned above), wherein the fifth connecting segment 722 extends in the direction away from the fourth connecting segment 721 towards the direction away from the second end plate 14.

[0088] By setting the above-mentioned first connecting member 71 and second connecting member 72, the first connecting shaft segment 32 can be connected to the traction device 203 through the first connecting member 71, and the second connecting shaft segment 33 can be connected to the traction device 203 through the second connecting member 72, thereby making the connection between the first connecting shaft segment 32 and the traction device 203, and the connection between the second connecting shaft segment 33 and the traction device 203 more flexible.

[0089] In addition, the second connecting section 712 of the first connecting member 71 extends in a direction away from the first connecting section 711 toward a direction away from the first end plate 13, and the fifth connecting section 722 of the second connecting member 72 extends in a direction away from the fourth connecting section 721 toward a direction away from the second end plate 14. In this way, the first connecting member 71 and the second connecting member 72 both form a bending structure, which can avoid interference between the first connecting member 71, the second connecting member 72 and the compacting roller 10 when the compacting roller 10 rolls.

[0090] In addition, it can be understood that in actual operation, the compaction roller 10 will not only rotate relative to the rotating shaft 30, but also have a certain degree of shaking in its axial direction. By forming a bending structure of the first connecting member 71 and the second connecting member 72, the first connecting member 71 and the second connecting member 72 have a movable margin in the axial direction of the compaction roller 10, thereby improving the structural strength of the first connecting member 71 and the second connecting member 72 and avoiding the first connecting member 71 and the second connecting member 72 from breaking.

[0091] For further information, please refer to Figure 6-Figure 7 The connecting assembly 70 further includes a third connecting member 73, which extends along the axial direction of the compacting roller 10, one end of which is connected to the third connecting segment 713, and the other end of which is connected to the sixth connecting segment 723. By providing the third connecting member 73, the first connecting member 71 and the second connecting member 72 can be connected together, and when the compacting roller 10 is in operation, the overall rolling balance of the compacting roller 10 is better.

[0092] It can be understood that when the compaction device 200 is actually working, the tractor 201 is located at the top of the slope, and the compaction 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 compaction roller 10. Therefore, the weight of the tractor 201 and the weight of the compaction 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.

[0093] See also Figure 2 and Figure 8 The compacting device 200 further includes a counterweight box 204, in which a counterweight liquid storage chamber is provided. The counterweight box 204 is provided on the vehicle body 2011 and is located on the side of the traction device 203 away from the compacting roller 10. By providing the counterweight liquid storage chamber in the counterweight box 204, liquid (such as water, etc.) can be stored in the counterweight liquid storage chamber, so that the weight of the liquid stored in the counterweight liquid storage chamber can be adjusted according to actual needs, thereby adjusting the overall weight of the traction vehicle 201, so as to balance the weight between the traction vehicle 201 and the compacting roller 10, and prevent the traction vehicle 201 from rolling over at the top of the slope.

[0094] For further information, see Figure 8The counterweight box 204 is provided with a counterweight liquid injection port 2041, through which liquid can be transported into the counterweight box 204 to adjust the overall weight of the tractor 201. The counterweight liquid injection port 2041 can also be used to discharge the liquid in the counterweight box 204. It can be understood that in transporting liquid into the counterweight box 204, the above-mentioned liquid infusion tube 20 for transporting liquid into the compacting roller 10 can be used, and another liquid infusion tube can also be used, which is not limited in the present application.

[0095] like Figure 8 As shown in , the compacting device 200 further includes a power generation device 205 and an electric control box 202. The power generation device 205 and the electric control box 202 are both arranged on the vehicle body 2011. The power generation device 205 can 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 electric control box 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.

[0096] 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.
