[0049] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] like Figures 1 to 15 As shown, an embodiment of the present invention provides a coal leveling system, including a gantry frame 1; the coal leveling system also includes: a first drive component 33, a first transmission member 31, a second transmission member 32 and a scraper mechanism 2; the first transmission member 31 is fixed on the gantry frame 1 and extends along the first direction; the second transmission member 32 is transmission-connected to the first drive component 33, and the second transmission member 32 is also connected to the first transmission member 31; the scraper mechanism 2 is connected to the first drive component 33, and the first drive component 33 drives the second transmission member 32 to move on the first transmission member 31 along the first direction, so that the first drive component 33 and the scraper mechanism 2 can move along the first direction, and the working width of the scraper mechanism 2 can be adjusted.

[0051] The flat coal system provided in this embodiment has a gantry frame 1 as an integral supporting structure, which is erected above the train track. The gantry frame 1 includes a crossbeam and columns 11 located on both sides of the crossbeam. The first transmission member 31 is arranged on the gantry frame 1, preferably on the columns 11 of the gantry frame 1. The first transmission member 31 extends along a first direction. The first transmission member 31 is used to provide guidance and support for the second transmission member 32; the second transmission member 32 is connected to the first drive assembly 33 in transmission connection. The second transmission member 32 is also connected to the first transmission member 31. The first drive assembly 33 is used to provide power to the second transmission member 32 so that the second transmission member 32 can move on the first transmission member 31 along the first direction. Moreover, in this embodiment, when the second transmission member 32 moves along the first transmission member 31, When moving in the first direction, the first drive assembly 33 moves synchronously with the second transmission member 32 in the first direction; further, the scraper mechanism 2 for leveling coal is connected to the first drive assembly 33, so that when the first drive assembly 33 moves in the first direction, the scraper mechanism 2 moves synchronously with the first drive assembly 33 and the second transmission member 32 in the first direction; the first drive assembly 33, the first transmission member 31 and the second transmission member 32 cooperate to drive the scraper mechanism 2 to move in the first direction, so that the scraper mechanism 2 can approach the carriage for leveling coal, or the scraper mechanism 2 can be moved away from the carriage. The operating width of the scraper mechanism 2 can be adjusted. When in use, its own operating width can be adjusted according to the type of carriage to meet the width requirements of different types of carriages. Among them, the above-mentioned first direction is preferably a vertical direction.

[0052] In this embodiment, by setting a scraper mechanism 2 with an adjustable working width, compared with the prior art, it is achieved that a set of coal-leveling system can simultaneously meet the coal-leveling operations of different types of carriages, which can save space while reducing costs, and can also facilitate inspection and maintenance operations in subsequent applications, and has higher economic benefits.

[0053] Preferably, in this embodiment, the first transmission member 31 is a first rack, and correspondingly, the second transmission member 32 is a first gear matched with the first rack, and the first gear meshes with the first rack; the first driving assembly 33 is an electric motor, an internal combustion engine or a pneumatic motor, etc., and the first gear is driven to rotate by the first driving assembly 33, thereby driving the scraper mechanism 2 connected to the first driving assembly 33 to move along the extension direction of the first rack. The first gear and the first rack are used to drive the scraper mechanism 2 to move, which has high transmission efficiency, strong load capacity, and more accurate positioning.

[0054] It is understandable that, in this embodiment, the first transmission member 31 can also be a lead screw, and the second transmission member 32 can be a nut matched with the lead screw; the nut is driven to rotate by the first driving assembly 33, so that the nut moves along the extension direction of the lead screw. Although the lead screw and the nut cannot withstand a large load when they are matched, this embodiment can solve this problem well by providing a clamping assembly 34 matched with the gantry frame 1.

[0055] The coal leveling system provided by the embodiment of the present invention is as follows: Figures 1 to 10 As shown, the scraper mechanism 2 includes a fixed scraper assembly 21, a movable scraper assembly 22 and a second drive assembly 23; the second drive assembly 23 is transmission-connected to the movable scraper assembly 22, and the second drive assembly 23 drives the movable scraper assembly 22 to move in the width direction relative to the fixed scraper assembly 21 to adjust the working width of the scraper mechanism 2.

[0056] In this embodiment, the scraper mechanism 2 includes a fixed scraper assembly 21, a mobile scraper assembly 22 and a second drive assembly 23; the fixed scraper assembly 21 is fixedly arranged, and the working width of the fixed scraper assembly 21 is the minimum working width of the scraper mechanism 2; the second drive assembly 23 is transmission-connected to the mobile scraper assembly 22, and is used to drive the mobile scraper assembly 22 to move in the width direction relative to the fixed scraper assembly 21, thereby increasing the working width of the scraper mechanism 2 and realizing the adjustment of the working width of the scraper mechanism 2 to meet the width requirements of different types of carriages.

[0057] The coal leveling system provided by the embodiment of the present invention is as follows: Figure 7 As shown, the fixed scraper assembly 21 is provided with a receiving space 24 , and the movable scraper assembly 22 can be received in the receiving space 24 .

[0058] In the present embodiment, a receiving space 24 is provided in the fixed scraper assembly 21, and the above-mentioned mobile scraper assembly 22 can be accommodated in the receiving space 24, so as to protect the mobile scraper assembly 22 when the mobile scraper assembly 22 is not in use, and to prevent coal particles from getting stuck in the mobile scraper assembly 22 and causing the mobile scraper assembly 22 to get stuck during movement. Preferably, the above-mentioned second drive assembly 23 is also arranged in the receiving space 24, so as to prevent coal particles from affecting the second drive assembly 23. At least one end of the receiving space 24 in the width direction is open, so that the mobile scraper assembly 22 can extend or retract into the receiving space 24. The mobile scraper assembly 22 moves in the width direction relative to the fixed scraper assembly 21, so that the overall height of the scraper mechanism 2 can be reduced, and the arrangement of the mobile scraper assembly 22 is convenient. When in use, the above-mentioned width direction and height direction are Figure 6 It has been shown in Figure 6 The direction perpendicular to the paper plane is the front-to-back direction.

[0059] Optionally, in this embodiment, the fixed scraper assembly 21 includes a front scraper 211 and a rear scraper 212, and the front scraper 211 and the rear scraper 212 are arranged at intervals along the front-to-back direction; the front scraper 211 and the rear scraper 212 cooperate to achieve multi-level leveling, which can improve the efficiency and uniformity of leveling. The above-mentioned accommodating space 24 is arranged between the front scraper 211 and the rear scraper 212, which can maximize the use of the internal space of the scraper mechanism 2, thereby reducing the space occupied by the scraper mechanism 2, facilitating the arrangement of the mobile scraper assembly 22 without affecting the operation of the fixed scraper assembly 21, and the equipment has strong integrity. Since the accommodating space 24 is located between the front scraper 211 and the rear scraper 212, both ends of the accommodating space 24 in the width direction are open, and then the mobile scraper assembly 22 can be extended from any end of the accommodating space 24 in the width direction or retracted into the accommodating space 24.

[0060] It is understandable that, in this embodiment, the above-mentioned accommodating space 24 can also be formed by providing a hollow box on the scraper mechanism 2, which can also achieve the purpose of accommodating the moving scraper assembly 22 and the second driving assembly 23 in this embodiment.

[0061] The coal leveling system provided by the embodiment of the present invention is as follows: Figures 3 to 5 As shown, the movable scraper assembly 22 includes two movable scrapers 221; the second driving assembly 23 includes a driving motor 231, a second gear 233 and a second rack 232 corresponding to the movable scraper 221; the two second racks 232 are both slidably arranged in the accommodating space 24 and are connected to the corresponding movable scrapers 221; the second gear 233 is arranged at the output end of the driving motor 231, and the driving motor 231 drives the second gear 233 to rotate; the two second racks 232 are both meshed with the second gear 233, and the tooth surfaces of the two second racks 232 are arranged opposite to each other.

[0062] In this embodiment, the above-mentioned mobile scraper assembly 22 includes two mobile scrapers 221, and the two mobile scrapers 221 are both connected to the second drive assembly 23. The second drive assembly 23 simultaneously drives the two mobile scrapers 221 to move in the width direction relative to the fixed scraper assembly 21, and the two mobile scraper assemblies 22 move toward or away from each other during movement, that is, the mobile scrapers 221 are extended or retracted at both ends of the width direction of the accommodating space 24. By setting two mobile scrapers 221, the adjustment efficiency can be improved. At the same time, compared with setting one mobile scraper 221, when two mobile scrapers 221 are set at the same working width of the scraper mechanism 2, the width dimension of the mobile scraper 221 is lower, so that the structural strength is higher, and damage during flat coal operation is avoided.

[0063] In this embodiment, the working width of the fixed scraper assembly 21 is set to L1, and the working width of the mobile scraper assembly 22 is set to L2. At this time, the working width adjustment range L of the scraper mechanism 2 is L1≤L≤L1+2*L2. The above is the working width range of the scraper mechanism 2 when the mobile scraper 221 moves along the width direction of the fixed scraper assembly 21. When the mobile scraper 221 moves along the height direction of the scraper mechanism 2, the working width range L of the scraper mechanism 2 is L1 and L1+2*L2, or L1 and L1+L2. The former is that the mobile scraper assembly 22 is only provided with one mobile scraper 221, and the latter is that the mobile scraper assembly 22 is provided with two mobile scrapers 221. When the mobile scraper 221 moves along the height direction of the scraper mechanism 2, the mobile scraper 221 can be driven to move by a telescopic cylinder such as an air cylinder or an oil cylinder, or by a gear and a rack. At the same time, a limit track or other structure can be set on the frame of the scraper mechanism 2 to limit the mobile scraper 221. The mobile scraper 221 and the telescopic cylinder are both arranged on the equipment frame.

[0064] Further, the second driving assembly 23 includes a driving motor 231, a second gear 233 and a second rack 232. As mentioned above, two movable scrapers 221 are provided. Accordingly, two second racks 232 are also provided in this embodiment, and the two second racks 232 correspond to the two movable scrapers 221. The movable scrapers 221 are fixed on the corresponding second racks 232. The fixed scraper assembly 21 also includes an equipment frame, the front scraper 211 and the rear scraper 212 are fixed on the equipment frame, the driving motor 231 is also fixed on the equipment frame, and at least the output shaft of the driving motor 231 is located in the accommodating space 24, the second gear 233 is provided on the output shaft of the driving motor 231, the two second racks 232 are meshed with the second gear 233, and the tooth surfaces of the two second racks 232 are arranged oppositely, and the two second racks 232 can be driven to move toward or away from each other by the rotation of the driving motor 231, thereby achieving the purpose of the second driving assembly 23 driving the two movable scrapers 221 to move toward or away from each other. The driving motor 231 cooperates with the second gear 233 and the second rack 232, which has a simple structure, low cost and high reliability. At the same time, it can also drive the two moving scrapers 221 to move synchronously at the same time, and has high adjustment efficiency.

[0065] It is understandable that in this embodiment, the second driving assembly 23 may also use a telescopic cylinder such as a pneumatic cylinder or an oil cylinder, and each movable scraper 221 is provided with a corresponding telescopic cylinder or a double-headed telescopic cylinder, and the telescopic cylinder can also achieve the purpose of driving the movable scraper 221 to move along the width direction of the fixed scraper assembly 21 in this embodiment. Moreover, the telescopic cylinders of the two movable scrapers 221 can be controlled synchronously or individually, which can be set according to the actual use situation.

[0066] The coal leveling system provided by the embodiment of the present invention is as follows: Figure 5 , Figure 7 and Fig. 9 As shown, the scraper mechanism 2 also includes a guide assembly, which is arranged in the accommodating space 24; the guide assembly is used to limit the second rack 232, and / or the guide assembly is used to limit the movable scraper 221.

[0067] In this embodiment, in order to ensure the stability of the moving scraper 221 during movement, the scraper mechanism 2 is also provided with a guide assembly, which is used to limit at least one of the second rack 232 and the moving scraper 221. In this embodiment, the guide assembly is preferably used to limit the second rack 232 and the moving scraper 221 at the same time to improve the stability of the moving scraper 221 during movement.

[0068] Optionally, the coal-leveling system provided in this embodiment is as follows: Figure 5 , Figure 7 and Fig. 9 As shown, the guide assembly includes a guide slide 251 corresponding to the second rack 232; the guide slide 251 is fixed in the accommodating space 24 and extends along the width direction of the fixed scraper assembly 21, and the second rack 232 is slidably arranged in the corresponding guide slide 251.

[0069] In this embodiment, the guide slide 251 is used to limit the second rack 232. The second rack 232 is slidably arranged in the guide slide 251. The guide slide 251 is located in the accommodating space 24 and is fixedly connected to the above-mentioned equipment frame. The guide slide 251 extends along the width direction of the fixed scraper assembly 21. By setting the guide slide 251 to limit the second rack 232, the stability of the second rack 232 when sliding in the accommodating space 24 can be ensured, and the scraper mechanism 2 can be prevented from malfunctioning due to the heavy load on the moving scraper 221 during the coal leveling operation.

[0070] In this embodiment, the guide slide 251 can be a U-shaped structure, which can cover the three sides of the second rack 232 where no teeth are set; but since the second rack 232 also needs to be connected to the movable scraper 221, in order to increase the connection area between the second rack 232 and the movable scraper 221, thereby increasing the connection strength between the second rack 232 and the scraper, the guide slide 251 in this embodiment is preferably an L-shaped structure, which cooperates with the upper side of the second rack 232 and the side away from the teeth to limit the second rack 232, and the lower side of the second rack 232 is connected to the movable scraper 221.

[0071] Optionally, the coal-leveling system provided in this embodiment is as follows: Figure 5 , Figure 7 and Fig. 9As shown, the guide assembly includes a first guide rail 252 and a first guide wheel group 254 corresponding to the second rack 232; the first guide wheel group 254 is arranged on the corresponding second rack 232; the first guide rail 252 is fixed in the accommodating space 24 and extends along the width direction of the fixed scraper assembly 21, and the first guide wheel group 254 is slidably connected to the first guide rail 252.

[0072] In this embodiment, the guide assembly includes a first guide rail 252 and a first guide wheel group 254. The first guide wheel group 254 is connected to the corresponding second rack 232. The upper end of the first guide wheel group 254 is connected to the lower side of the second rack 232 to avoid affecting the cooperation between the second rack 232 and the guide slide 251. The lower end of the first guide wheel group 254 is connected to the moving scraper 221. The first guide wheel group 254 is slidably connected to the first guide rail 252. Through the cooperation between the first guide wheel group 254 and the first guide rail 252, the stability of the second rack 232 when sliding in the accommodating space 24 can be ensured, and the scraper mechanism 2 can be prevented from malfunctioning due to the large load on the moving scraper 221 during the coal leveling operation.

[0073] In this embodiment, the first guide rail 252 is preferably an H-shaped steel, so that the first guide rail 252 has two grooves arranged opposite to each other. The first guide rail 252 is located in the accommodating space 24, and the upper end surface of the first guide rail 252 is fixedly connected to the equipment frame. The first guide wheel group 254 includes a first wheel frame and a plurality of first guide wheels. The first guide wheels are arranged in two rows along the height direction of the first wheel frame, and each row has a plurality of first guide wheels. The first guide wheels of each row are arranged along the width direction of the first wheel frame, and all the first guide wheels are rotatably arranged on the first wheel frame. One row of the first guide wheels is located in the above-mentioned groove, and the other row of the first guide wheels cooperates with the lower end surface of the first guide rail 252.

[0074] In this embodiment, since two second racks 232 are provided, two groups of first guide wheel groups 254 directly connected to the second racks 232 can share one first guide rail 252, thereby reducing costs and facilitating layout. Preferably, in this embodiment, in order to further improve the stability of the second racks 232, two groups of first guide wheel groups 254 are provided corresponding to each second rack 232, wherein one group of first guide wheel groups 254 is directly connected to the second rack 232, and the other group of first guide wheel groups 254 is connected to the moving scraper 221, and the two groups of guide wheel groups are arranged oppositely and both cooperate with the first guide rail 252. By limiting the second rack 232 with two groups of first guide wheel groups 254, the stability of the second rack 232 can be greatly improved.

[0075] It can be understood that in this embodiment, the first guide rail 252 can also be a steel section such as a channel steel or an angle steel; when the first guide rail 252 is a channel steel or an angle steel, although it can also achieve the purpose of limiting the second rack 232 in cooperation with the first guide wheel group 254 in this embodiment, each group of first guide wheel groups 254 must be separately configured with a first guide rail 252.

[0076] Optionally, the coal-leveling system provided in this embodiment is as follows: Figure 5 , Figure 7 and Fig. 9 As shown, the guide assembly includes a second guide rail 253 and a second guide wheel group 255 corresponding to the movable scraper 221; the second guide wheel group 255 is arranged on the corresponding movable scraper 221; the second guide rail 253 is fixed in the accommodating space 24 and extends along the width direction of the fixed scraper assembly 21, and the second guide wheel group 255 is slidably connected to the second guide rail 253.

[0077] In this embodiment, the second guide rail 253 cooperates with the second guide wheel group 255 to guide and limit the movable scraper 221, thereby ensuring the stability of the movable scraper 221 when sliding in the accommodating space 24, and avoiding the scraper mechanism 2 from malfunctioning due to the large load on the movable scraper 221 during the coal leveling operation. The second guide wheel group 255 includes a second wheel frame and a plurality of second guide wheels, and the second guide wheels are rotatably arranged on the second wheel frame and arranged along the width direction of the second wheel frame. The second guide wheel group 255 is provided on both sides of the movable scraper 221 in the front and rear directions.
