Description

Technical Field

[0001] The present invention belongs to the technical field of unloading devices, and specifically relates to an intelligent double - screw car unloader with high - precision automatic recognition and anti - contact with the wall. Background Technique

[0002] Coal is a solid combustible organic rock and is one of the most widely distributed fossil fuels. When transporting a large amount of coal, it is usually carried out by means of a train carriage, which is a part of the train carriage specifically used for storing coal and plays an important role in the field of coal transportation, providing strong support for coal transportation.

[0003] After the coal is transported to the destination in the train carriage, it is usually necessary to use a car unloader to unload the coal. The existing car unloader mainly conducts the unloading operation by controlling the up - down and left - right movement of the double - screw unloading rod. In order to ensure that the double - screw unloading rod does not touch the inner wall of the train carriage, the moving distance is usually limited. However, the existing limit is controlled by a manual switch, which is at a relatively high position and mainly relies on the work experience of the operator to judge, and cannot be accurately controlled. In addition, the bottom of the train carriage is not flat and there are uneven situations, so that a relatively thick coal layer will remain in the train carriage after the car unloader works. At this time, it is necessary for the operator to scrape the coal manually, resulting in an increase in the workload of the operator. Therefore, it is necessary to improve this situation.

When the rangefinder measures the length of the train carriage, it will transmit the signal to the controller through the single-chip microcomputer. The controller will control the air cylinder to start, so that the triangular block moves along the inner surface of the fixed frame and squeezes the movable rod, causing the movable rod to drive the round rod, the connecting rod and the second brake pad to move and compress the spring. In this way, the unloader can be braked in time with the mutual cooperation of the second brake pad and the first brake pad, so as to ensure that the unloader can move accurately left and right inside the train carriage and prevent the double spiral discharge rod from touching the left and right inner walls of the train carriage.

Specific implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] As Figures 1 to 9As shown in the figure, an embodiment of the present invention provides a high-precision automatic recognition and wall-touching-preventing intelligent double-helix car unloader, which includes a bottom plate 1. In the middle of the top end of the bottom plate 1, a fixed box 2 is fixedly installed. On the left and right sides of the middle part of the top end of the bottom plate 1, a controller 3 and a single-chip microcomputer 4 located inside the fixed box 2 are respectively fixedly installed. In the middle of the bottom end of the bottom plate 1, a first telescopic rod 5 is fixedly installed. At the bottom end of the first telescopic rod 5, a square frame 6 is fixedly installed. Inside the bottom end of the square frame 6, an ultrasonic probe 7 is fixedly sleeved. On the left and right sides of the top end of the bottom plate 1, limiting plates 8 are respectively fixedly installed. On the outer surface of the top of the limiting plate 8, an upper cross bar 9 is movably sleeved. The number of the upper cross bars 9 is two and their shapes and sizes are the same. On the outer surface of the bottom of the limiting plate 8, a lower cross bar 10 is movably sleeved. The number of the lower cross bars 10 is two. The bottom ends of the two lower cross bars 10 are respectively movably connected to the top end of the bottom plate 1. On the left and right sides of the top ends of the two lower cross bars 10, sensors 11 are respectively fixedly installed. In the middle of the opposite surfaces of the two lower cross bars 10, inclined rods 12 are respectively hinged. The other end of the inclined rod 12 is hinged to a rectangular block 13. The bottom end of the rectangular block 13 is movably connected to the top end of the fixed box 2. At the rear side of the middle part of the top end of the fixed box 2, a power motor 14 is fixedly installed. The other end of the output shaft of the power motor 14 is fixedly sleeved with a lead screw 15. The front side of the outer surface of the lead screw 15 is threadedly sleeved with the inner surface of the rectangular block 13.

[0029] After the ultrasonic probe 7 is started, it will detect the depth of the train car cabin. Then the ultrasonic probe 7 transmits the depth signal to the single-chip microcomputer 4, and the single-chip microcomputer 4 then transmits the signal to the controller 3. The controller 3 controls the power motor 14 to start, causing the lead screw 15 to rotate. As a result, the rectangular block 13 threadedly sleeved with the lead screw 15 drives one end of the inclined rod 12 to move along the top end of the fixed box 2. Furthermore, the other end of the inclined rod 12 generates a pulling force on the lower cross bar 10, pulling the lower cross bar 10 with the sensor 11 to move along the outer surface of the limiting plate 8. At this time, when the upper cross bar 9 moves down and contacts the sensor 11, the sensor 11 will transmit the signal to the single-chip microcomputer 4 and the controller 3. Thus, through the controller 3, the upper cross bar 9 is made to stop moving down. In this way, the descending height of the car unloader can be adjusted more precisely according to the depth of the train car cabin, ensuring that the coal is unloaded more cleanly while avoiding touching the wall.

[0030] Among them, vertical rods 16 are respectively fixedly sleeved inside the left and right ends of the two upper cross bars 9. The bottom ends of the vertical rods 16 penetrate through the bottom plate 1 and extend to the bottom of the bottom plate 1. On the left and right sides of the top end of the bottom plate 1, second telescopic rods 17 located inside the fixed box 2 are respectively fixedly installed. The bottom ends of the second telescopic rods 17 penetrate through the bottom plate 1 and extend to the bottom of the bottom plate 1 and are fixedly installed with lifting frames 18. The number of the lifting frames 18 is two. The top ends of the two lifting frames 18 are respectively movably connected to the left and right sides of the bottom end of the bottom plate 1. The front and rear sides of the top ends of the two lifting frames 18 are respectively fixedly connected to the bottom ends of the vertical rods 16.

[0031] After the second telescopic rod 17 is activated, the lifting frame 18 will drive the vertical rod 16 and the upper cross bar 9 to move downward. At the same time, the controller 3 can control the start and stop of the second telescopic rod 17, so as to facilitate the control of the lifting of the lifting frame 18 through the controller 3.

[0032] Among them, fixing plates 19 are respectively fixedly sleeved in the middle parts of the bottoms of the two lifting frames 18. At the top of the left end of the fixing plate 19, a driving motor 20 is fixedly installed. The other end of the output shaft of the driving motor 20 is fixedly sleeved with a driving shaft 21. The other end of the driving shaft 21 penetrates through the fixing plate 19 and extends to the right side of the fixing plate 19. An active wheel 22 is fixedly sleeved on the outer surface of the driving shaft 21. The outer surface of the active wheel 22 is movably sleeved with the inner surface of the fixing plate 19.

[0033] After the driving motor 20 is activated, the driving shaft 21 will drive the active wheel 22 to rotate. At the same time, the start and stop of the driving motor 20 can be controlled by the controller 3.

[0034] Among them, a driven wheel 23 is movably sleeved at the bottom end inside the fixing plate 19. The driven wheel 23 is connected to the active wheel 22 through a transmission belt 24. A double spiral discharge rod 25 is fixedly sleeved inside the driven wheel 23. The left and right ends of the double spiral discharge rod 25 respectively penetrate through the fixing plate 19 and extend to the outside of the fixing plate 19.

[0035] When the active wheel 22 rotates, since the active wheel 22 is connected to the driven wheel 23 through the transmission belt 24, under the action of the active wheel 22 and the transmission belt 24, the driven wheel 23 will drive the double spiral discharge rod 25 to rotate. At the same time, spiral blades are arranged on the outer surface of the double spiral discharge rod 25, so that the unloading of coal inside the train car cabin can be realized through the double spiral discharge rod 25.

[0036] Among them, first bearings 26 are respectively fixedly installed at the front and rear ends on the right side of the bottom end of the bottom plate 1. A round shaft 27 is movably sleeved inside the first bearing 26. Roller wheels 28 are respectively fixedly sleeved on the front and rear sides of the outer surface of the round shaft 27. The bottom of the outer surface of the roller wheel 28 is movably sleeved with a guide rail 29. First brake pads 30 are respectively fixedly connected to the inner walls on the front and rear sides of the guide rail 29.

[0037] Due to the existence of the guide rail 29, it will play a role in guiding and limiting the rotation and movement of the roller wheel 28. And due to the existence of the first bearing 26, it ensures that the round shaft 27 can rotate stably along the inner surface of the first bearing 26.

[0038] Among them, a dual-axis motor 31 is fixedly installed on the left side of the bottom end of the bottom plate 1. The other end of the output shaft of the dual-axis motor 31 is fixedly sleeved with a rotating shaft 32. The outer surface of the rotating shaft 32 is fixedly sleeved with a driving wheel 33. The outer surface of the driving wheel 33 is movably sleeved with the inner surface of the guide rail 29. The outer surface of the rotating shaft 32 is movably sleeved with a second bearing 34. The top end of the second bearing 34 is fixedly connected to the bottom end of the bottom plate 1.

[0039] After the dual-axis motor 31 is started, it will cause the rotating shaft 32 to drive the driving wheel 33 to rotate along the inner surface of the second bearing 34. Since the driving wheel 33 is movably sleeved inside the guide rail 29, as the driving wheel 33 rotates, the bottom plate 1 will move. At the same time, the controller 3 can control the start and stop of the dual-axis motor 31.

[0040] Among them, a rangefinder 35 is fixedly sleeved inside the top end of the square frame 6. A fixed frame 36 is fixedly installed at the left end of the bottom plate 1. An air cylinder 37 is fixedly installed at the bottom of the left end of the fixed box 2. The bottom end of the air cylinder 37 is fixedly installed with a triangular block 38. The outer surface of the triangular block 38 is movably sleeved with the inner surface of the fixed frame 36.

[0041] After the rangefinder 35 is started, it will accurately measure the length of the train carriage. Then the rangefinder 35 transmits the signal to the single-chip microcomputer 4, and the single-chip microcomputer 4 transmits the signal to the controller 3. Finally, the controller 3 controls the start and stop of the air cylinder 37, thereby controlling the up and down movement of the triangular block 38.

[0042] Among them, limiting rods 39 are fixedly installed at the bottoms of the inner walls on the left and right sides of the fixed frame 36. The left and right sides of the middle part of the outer surface of the limiting rod 39 are respectively movably sleeved with movable rods 40. The number of the movable rods 40 is two. The outer surfaces of the two movable rods 40 are respectively movably sleeved with the inner surface of the fixed frame 36. The tops of the opposite surfaces of the two movable rods 40 are respectively movably connected to the left and right sides of the triangular block 38.

[0043] The tops of the opposite surfaces of the two movable rods 40 are arc surfaces, and the left and right sides of the triangular block 38 are inclined surfaces. When the triangular block 38 moves downward along the inner surface of the fixed frame 36, it will squeeze the arc surfaces of the movable rods 40, so that the two movable rods 40 move away from each other along the outer surface of the limiting rod 39.

[0044] Wherein, springs 41 are respectively and fixedly installed at the bottom parts of the opposite sides of the two movable rods 40, the other ends of the springs 41 are fixedly connected to the inner surface of the fixed frame 36, round rods 42 are respectively and fixedly installed at the bottom parts of the opposite sides of the two movable rods 40, the other ends of the round rods 42 penetrate through the fixed frame 36 and extend to the outside of the fixed frame 36 and are fixedly installed with connecting rods 43, the number of the connecting rods 43 is two, the opposite surfaces of the two connecting rods 43 are respectively movably connected to the left and right sides of the fixed frame 36, and second brake pads 44 are respectively and fixedly installed on the opposite surfaces of the two connecting rods 43.

[0045] When the two movable rods 40 move away from each other, they will drive the round rods 42, the connecting rods 43 and the second brake pads 44 to move together and compress the springs 41. Under the restoring action of the springs 41, the movable rods 40 will be forced to return to their original positions. In this way, through the mutual cooperation of the second brake pads 44 and the first brake pads 30, the unloader can be timely braked and stopped.

[0046] Working principle and usage process:

[0047] During unloading, the controller 3 will control the first telescopic rod 5 to start first, so that the box 6 moves downward with the ultrasonic probe 7 and the rangefinder 35, and then accurately measures the depth and length of the train compartment. The ultrasonic probe 7 will emit an ultrasonic wave of a specific frequency. This part of the ultrasonic wave will pass through the coal layer accumulated in the train compartment, and then be reflected back after contacting the bottom of the train compartment. After receiving the reflected ultrasonic wave, the ultrasonic probe 7 will calculate the depth of the train compartment based on the round-trip time and the propagation speed of the ultrasonic wave. Then the ultrasonic probe 7 will transmit the measured depth signal to the single-chip microcomputer 4, and the single-chip microcomputer 4 will transmit the signal to the controller 3. At this time, the controller 3 will control the power motor 14 to start, so that the screw 15 rotates, so that the rectangular block 13 threadedly connected to the screw 15 moves with one end of the inclined rod 12, so that the other end of the inclined rod 12 generates a pulling force on the lower cross bar 10, pulling the lower cross bar 10 with the sensor 11 along the limit plate 8 The outer surface of the upper cross bar 9 moves upward until the spacing between the lower cross bar 10 and the upper cross bar 9 is consistent with the depth of the train compartment. Then the controller 3 controls the power motor 14 to stop and start the drive motor 20, so that the drive shaft 21 rotates with the driving wheel 22. Since the driving wheel 22 is connected to the driven wheel 23 through the transmission belt 24, the driven wheel 23 will rotate with the double-helical unloading rod 25, thereby unloading the coal through the double-helical unloading rod 25. Then the controller 3 controls the second telescopic rod 17 to start, so that the lifting frame 18 moves downward with the upper cross bar 9 through the vertical rod 16. When the upper cross bar 9 contacts the sensor 11, the sensor 11 will send a signal to the single-chip microcomputer 4, and the single-chip microcomputer 4 will then transmit the signal to the controller 3. The controller 3 will control the second telescopic rod 17 to stop, so that the descending height of the unloading machine can be more accurately adjusted according to the depth of the train compartment, so that the coal can be unloaded more cleanly while ensuring that it does not touch the bottom of the train compartment, thereby reducing the workload of the operator.

[0048] Meanwhile, the rangefinder 35 will transmit the measured length signal to the single-chip microcomputer 4, and the single-chip microcomputer 4 will then transmit the signal to the controller 3. After receiving the signal transmitted by the single-chip microcomputer 4, the controller 3 will control the dual-axis motor 31 to start, so that the rotating shaft 32 drives the driving wheel 33 to rotate, and then the unloader moves left and right along the guide rail 29 within the range measured by the rangefinder 35. When the unloader moves to the boundary of the length range, the controller 3 will control the air cylinder 37 to start, so that the triangular block 38 moves downward and squeezes the movable rod 40. At this time, the two movable rods 40 will respectively drive the round rod 42, the connecting rod 43 and the second brake pad 44 to move away from each other along the outer surface of the limiting rod 39 and compress the spring 41, so as to stop the unloader in time in cooperation with the second brake pad 44 and the first brake pad 30. After the unloader stops, the controller 3 will control the air cylinder 37 to reset and control the dual-axis motor 31 to reverse, so that the unloader moves to the other side, and by repeating this cycle, the precise movement of the unloader in the left and right directions inside the train car body can be realized, thus preventing the double-helix discharge rod 25 from touching the left and right inner walls of the train car body.
