Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal transportation technology, specifically to a coal leveling and compaction device. Background Technology
[0002] Due to the varying density of coal, the railway loading system sometimes fails to meet the train's rated load capacity when loading lighter coals into a single car, resulting in a shortfall in tonnage and increased transportation costs. Loading according to the train's rated load capacity would cause the material to exceed the height of the car sides, leading to loose material pollution and compromising transportation safety. Furthermore, after loading, the coal inside the train is often uneven. Therefore, coal leveling and compaction devices are frequently used to compress the coal exceeding the car side height to the same level or lower, simultaneously flattening the coal to meet railway transportation standards.
[0003] Traditional coal compaction equipment includes an electric hoist, a frame, a fixed plate, a controller, and a pressure roller. The fixed plate and one end of the frame are rotatably connected, the electric hoist is connected to the other end of the frame, and the pressure roller is rotatably connected to the frame. The worker controls the electric hoist to pull the frame through the controller, so that the frame rotates around the rotation axis of the frame and the fixed plate, and then lifts the pressure roller into the train to compact the coal.
[0004] However, since coal trains are usually operated in a mixed formation mode, the height of each train car is different. Workers need to adjust and control the depth of the pressure rollers entering the side of each train car to keep the depth of the pressure rollers entering the side of each train car consistent, which is time-consuming and labor-intensive. Utility Model Content

[0040] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0041] like Figures 1-2 As shown, one embodiment of this utility model provides a coal compaction device, including a lifting mechanism, a fixing plate and a controller, as well as a frame 1, a pressure roller 2 and a positioning mechanism 3;
[0042] A fixed plate is connected to one side of the frame 1, and a lifting mechanism is connected to the other side. The lifting mechanism is used to drive the frame 1 to rotate around the rotation axis of the frame 1 and the fixed plate.
[0043] The pressure roller 2 is rotatably connected to the frame 1, and the bottom end of the pressure roller 2 is lower than the frame 1;
[0044] The positioning mechanism 3 is used to position the depth to which the pressure roller 2 enters the side of the train;
[0045] Both the positioning mechanism 3 and the lifting mechanism are electrically connected to the controller.
[0046] In practical applications, the lifting mechanism can be an electric hoist. A controller can lock the electric hoist and control the lifting mechanism to pull the frame 1 to rotate around the rotation axis of the frame 1 and the fixed plate, thus adjusting the height of the pressure roller 2 rotatably connected to the frame 1. The controller, lifting mechanism, and fixed plate are not shown in the diagram.
[0047] When the pressure roller 2 compacts the coal, the bottom end of the pressure roller 2 is lower than the frame 1. Preferably, the pressure roller 2 is rotatably connected to the side of the frame 1 away from the rotation axis. Specifically, a drive shaft is rotatably connected to the pressure roller 2, and the axis of the drive shaft coincides with the axis of the pressure roller 2. Bearing seats are installed at the bottom of both sides of the frame 1, and a third bearing is installed in the bearing seat. The drive shaft is connected to the third bearing, thereby rotatably connecting the pressure roller 2 to the frame 1.
[0048] The positioning mechanism 3 positions the pressure roller 2 to the depth of the train car side and sends a signal to the controller. The controller controls the lifting mechanism to lock, and the pressure roller 2 is kept at the corresponding height. The train moves forward, and the pressure roller 2 compacts the coal, thus pressing down coal that exceeds the height of the train car side. When using a mixed train mode, there is no need to manually adjust the depth of the pressure roller 2 entering the side of each train car, saving time and effort.
[0049] According to one embodiment of the present invention, the positioning mechanism 3 includes a combination frame, a combination rod, and a proximity switch 301;
[0050] The combination rod is rotatably connected to the combination frame, the proximity switch 301 is connected to the combination frame, and the proximity switch 301 is located on one side of the combination rod.
[0051] During the process of lowering the pressure roller 2 by the lifting mechanism, the end of the combined rod away from the combined frame contacts the side of the train and rotates, causing the combined rod to approach the proximity switch 301 until it contacts the proximity switch 301. Then, the proximity switch 301 sends a signal to the controller, and the controller controls the lifting mechanism to lock, so that the pressure roller 2 can be kept in this position to flatten the coal.
[0052] Of course, in this embodiment, the positioning mechanism 3 can also take other forms. For example, the positioning mechanism 3 includes a connecting rod connected to one side of the frame 1, with a pressure sensor connected to the end of the connecting rod away from the frame 1. When the pressure sensor contacts the side of the train, it sends a signal to the controller, which then controls the lifting mechanism to lock, allowing the train to move forward and causing the pressure roller 2 to rotate and flatten the coal. Its purpose does not depart from the design concept of this utility model; therefore, it should be considered part of the design concept of this utility model.
[0053] According to one embodiment of the present invention, the positioning mechanism 3 further includes a limiting member;
[0054] The limiting component is located on the side of the combination rod away from the proximity switch 301;
[0055] The limiting component is used to restrict the rotation angle of the combination rod.
[0056] The limiting component is fixed on the assembly frame. By setting the limiting component, the rotation angle of the assembly rod can be restricted, preventing the assembly rod from rotating to the other side and failing to contact the proximity switch 301, thus preventing failure.
[0057] Preferably, the maximum included angle between the combined rod and the combined frame is 130°, which makes the combined rod rotate more smoothly after contacting the side of the train. After the combined rod contacts the side of the train, it continues to rotate and gradually approaches the proximity switch 301.
[0058] According to one embodiment of the present invention, the proximity switch 301 is connected to the assembly frame via an adjustment component, which is used to adjust the distance between the proximity switch 301 and the limiting member.
[0059] The distance between the proximity switch 301 and the limiter is adjusted by the set adjustment component, thereby changing the size of the included angle between the combined rod and the combined frame when the combined rod and the proximity switch 301 are in contact. This adjusts the longitudinal distance from the bottom of the pressure roller 2 to the end of the combined rod away from the combined frame, and changes the depth of the pressure roller 2 into the side of the train car. This allows the pressure roller 2 to flatten the coal while pressing it to be flush with or below the side of the train car, thus improving its practicality.
[0060] According to one embodiment of the present invention, the adjusting assembly includes a strip plate 302, a first adjusting bolt 303, and a first adjusting nut;
[0061] The strip plate 302 has a strip hole 304, and the first adjusting bolt 303 passes through the strip hole 304 and is screwed with the first adjusting nut;
[0062] A proximity switch 301 is connected to the end of the first adjusting bolt 303 away from the first adjusting nut;
[0063] Strip plate 302 is connected to the assembly frame.
[0064] According to one embodiment of the present invention, the limiting member includes a second adjusting bolt 312, a limiting sleeve 313, and a second adjusting nut;
[0065] The second adjusting bolt 312 passes through the strip plate 302, the base 311 and the limiting sleeve 313 in sequence and is then screwed into the second adjusting nut.
[0066] Specifically, loosen the first adjusting nut so that the first adjusting bolt 303 can slide in the strip hole 304, thereby changing the position of the proximity switch 301 connected to the first adjusting bolt 303. After adjustment, tighten the first adjusting nut to fix the proximity switch 301.
[0067] In the initial position, the probe 305 contacts the side wall of the limiting sleeve 313 under its own weight, and the limiting sleeve 313 is annular. Along the axial direction of the first adjusting bolt 303, the probe 305 is offset from the first adjusting bolt 303, and the first adjusting bolt 303 does not interfere with the rotation of the probe 305, allowing the probe 305 to rotate and contact the proximity switch 301.
[0068] Preferably, the included angle between the combined rod and the combined frame is between 100° and 130°. When the first adjusting bolt 303 is located at the leftmost end of the strip hole 304, the included angle between the combined rod and the combined frame is 100° when the combined rod contacts the proximity switch 301. When the first adjusting bolt 303 is located at the rightmost end of the strip hole 304, the included angle between the combined rod and the combined frame is 130° when the combined rod contacts the proximity switch 301. By adjusting the position of the proximity switch 301 within the strip hole 304, the included angle between the combined rod and the combined frame when the combined rod contacts the proximity switch 301 can be changed, thereby changing the depth of the pressure roller 2 entering the train side, thus improving practicality.
[0069] Furthermore, by turning the second adjusting nut, the angle between the combined frame and the strip plate 302 can be adjusted, thereby changing the position of the proximity switch 301, so that when the combined rod contacts the proximity switch 301, the depth of the pressure roller 2 entering the train side changes.
[0070] According to one embodiment of the present invention, the combined rod includes a probe rod 305, a rotating ring 306, a mounting shaft 308, and a roller 309;
[0071] The probe rod 305 is connected to a swivel ring 306 and a mounting shaft 308 at its two ends, respectively;
[0072] The swivel ring 306 is rotatably connected to the assembly frame via the connecting shaft 307, one end of which is connected to the assembly frame;
[0073] Rollers 309 are rotatably connected to the mounting shaft 308.
[0074] The roller 309 allows one end of the combination rod to move more smoothly on the side of the vehicle.
[0075] The swivel ring 306 is rotatably connected to the connecting shaft 307 via the first bearing, and the roller 309 is rotatably connected to the mounting shaft 308 via the second bearing. The first and second bearings enable the swivel ring 306 and the roller 309 to rotate more smoothly.
[0076] According to one embodiment of the present invention, the combined frame includes a fixed bracket 310 and a base 311 connected to each other;
[0077] The end of the fixed bracket 310 away from the base 311 is connected to the frame 1;
[0078] The connecting shaft 307 is connected to the base 311;
[0079] The strip plate 302 is connected to the base 311 by a limiting member.
[0080] According to one embodiment of the present invention, a connecting block 101 is connected to one end of the frame 1 away from the rotation axis, and the connecting block 101 is provided with a hoisting hole for connecting with the lifting mechanism.
[0081] According to one embodiment of the present invention, lifting blocks are connected to both sides of the frame 1.
[0082] By installing lifting blocks, safety ropes can be attached to them to prevent damage to the lifting mechanism and improve safety performance.
[0083] The axes of the pressure roller 2, the connecting shaft 307, the rotating shaft, and the mounting shaft 308 are all parallel to each other. The axis of the pressure roller 2 is parallel to the horizontal plane.
[0084] Specifically, in the initial position, the end of frame 1 closest to connecting block 101 is higher than the other end.
[0085] When the train reaches the designated position, the lifting mechanism slowly lowers frame 1, the pressure roller 2 decreases in height, and the roller 309 in the combined rod contacts the train side. The rotating ring 306 rotates around the connecting shaft 307, and then the detection rod 305 rotates around the connecting shaft 307 until one side of the detection rod 305 contacts the proximity switch 301. The proximity switch 301 sends a signal to the controller, which controls the lifting mechanism to lock. The train moves forward, and the pressure roller 2 rotates due to the friction of the coal in the train car, pressing the coal that is above the side of the car down to be level with or below the side of the car. After compaction, the controller controls the lifting mechanism to drive frame 1 to rotate, and the pressure roller 2 rises to the initial position. When the next train car reaches the designated position, the above steps are repeated to make the pressure roller 2 compact the coal in that car car. At this time, the depth of the pressure roller 2 into the side of the current train car is the same as the depth into the side of the previous train car, without the need for manual adjustment, saving time and effort.
