Description

Technical Field

[0001] The utility model relates to the technical field of cargo transportation, in particular to an intelligent unmanned control device for a dumper. Background Art

[0002] According to a tipping machine disclosed in Chinese patent number CN 212711783 U, it includes a turning wheel body, a hydraulic cylinder and an electric push rod. The middle part of the bottom end of the turning wheel body is connected to the hydraulic cylinder by bolts, the upper end of the hydraulic cylinder is connected to the support plate by bolts, the two sides of the bottom end of the turning wheel body are connected to the electric push rod by bolts, and one side of the electric push rod is connected to a hammer by bolts. The utility model is provided with an electric push rod and a hammer, when the turning wheel body drives the vehicle to turn over and unload, the electric push rod drives the hammer to continuously knock the bottom of the vehicle, so as to ensure that the material is completely discharged and reduce losses. By providing a dust cover and a fan, dust can be effectively reduced from entering. At the same time, the fan can also blow away the internal dust, so as to ensure the cleanliness of the rotating connection part of the power wheel and the turning wheel body, reduce friction resistance, and extend the service life.

[0003] The tipping machine in the prior art can effectively reduce the entry of dust, and at the same time, the internal dust can be blown away by the fan, thereby ensuring the cleanliness of the rotating connection between the power wheel and the flip wheel body, reducing friction resistance, and extending the service life. However, the following problems may exist in actual use: when flipping, most of the existing tipping machines have only one driving flipping structure, such as only motor drive or cylinder drive, which makes it difficult to flip over a heavy car body; secondly, when the existing equipment restricts the car body during the flipping process, it generally relies on a downward pressure force, but if the surface of the car body is uneven, the car body cannot be firmly restricted by this downward pressure alone, so an intelligent unmanned control device for a tipping machine is needed to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes an intelligent unmanned control device for a car tipping machine.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an intelligent unmanned control device for a tipping machine, comprising a base, a groove is provided in the middle of the base, a lower dividing cylinder is movably connected in the groove in the middle of the base, a movable interface is provided on the front of the lower dividing cylinder, an upper dividing cylinder is installed on the top of the lower dividing cylinder, the upper dividing cylinder and the lower dividing cylinder are integrated, side plates are welded on both sides of the groove of the base, a pushing cylinder group is installed on the inner side of one side of the side plate, a butt opening is provided on one side of the upper dividing cylinder, and the end of the pushing cylinder group is in contact with the butt opening and fits each other.

[0006] Preferably, a hook is welded to the top of the upper dividing cylinder, a pull rope is connected to one side of the hook, an output shaft is connected to the end of the pull rope, the pull rope is wound around the surface of the output shaft, and the end of the output shaft is transmission-connected to a winding motor group.

[0007] Preferably, rails are provided on both sides of the top of the lower sub-tube, and an infrared sensor is installed in the middle of the top of the lower sub-tube.

[0008] Preferably, a telescopic cylinder assembly is installed in the middle of the top end of the upper sub-tube, and a vibration plate is installed at the bottom end of the telescopic cylinder assembly.

[0009] Preferably, downward-pressing cylinder assemblies are installed on both sides of the top of the upper dividing cylinder, a clamp is threadedly connected to the bottom end of the downward-pressing cylinder assembly, electric push rods are installed on both sides of the clamp, and clamps are installed on the ends of the electric push rods.

[0010] Preferably, a frame is welded on the front and back sides of the bottom of one side of the upper sub-tube, a groove is provided in the middle of the frame, and a servo motor group is installed on the top of the frame.

[0011] Preferably, the bottom end of the servo motor group is transmission-connected with a driving shaft, the middle part of the driving shaft is threadedly connected with a turntable, one side of the turntable is threadedly connected with a connecting arm, and a sweeping plate is welded to the end of the connecting arm.

[0012] Beneficial Effects

[0013] In the utility model, after the infrared sensor senses that the vehicle has entered the tipping machine, it will transmit a signal to the control computer. The control computer will first transmit a command signal to the retracting motor group and the pushing cylinder group. After receiving the signal, the pushing cylinder group will control the cylinder column to extend forward. When the cylinder column extends forward, it will enter the stopper and then continue to extend forward. In the process of continuing to extend forward, the cylinder column will push the tipping machine in a clockwise direction. At the same time, after receiving the signal, the retracting motor group will control the output shaft to rotate counterclockwise. The counterclockwise rotation of the output shaft will reel in the pull rope, and the tipping machine will be pulled to one side by the pull rope. It should be noted that the movable interface on the front side of the lower sub-drum is for connecting the motor-driven flipping assembly. The device can make the tipping machine flip faster and reduce the wear of the output shaft of the motor flipping assembly by combining thrust, rotational force and pulling force.

[0014] In the utility model, after the control computer transmits signals to the pushing cylinder group and the winding motor group, it then transmits signals to the downward pressing cylinder assembly. The cylinder downward pressing assembly includes a cylinder body and a telescopic rod. After receiving the signals, the cylinder downward pressing assemblies on both sides will control the telescopic rod at the bottom to descend, and the bottom clamp will continue to descend to the state shown in the figure, and will be attached to the two sides of the top of the car body. The control computer then continues to transmit signals to the output ends of the electric push rods on both sides of the clamp. The output ends of the electric push rods control the push rods to push forward. When the electric push rods push forward, they will drive the clamps on both sides to get closer inward until the top of the car body is clamped. A pressure sensor is installed in the clamp. When the pressure sensor senses that the resistance and extrusion pressure of the car body wall reaches a limited value, it will transmit a stop signal to the output end of the electric push rod through the built-in MCU, and then the output end will control the electric push rod to stop extending forward, so that it can be ensured that the clamp can firmly clamp the car body. The weight of the clamp itself is large, and it contacts the top of the car body when pressed down, and pressure is applied. The car body can be well limited by cooperating with the clamping force of the clamp. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0024] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:

[0026] Reference Figure 1-6 The intelligent unmanned control device of the tipping machine includes a base 1, a groove is opened in the middle of the base 1, a lower dividing cylinder 17 is movably connected in the groove in the middle of the base 1, a movable interface 16 is opened on the front of the lower dividing cylinder 17, an upper dividing cylinder 3 is installed on the top of the lower dividing cylinder 17, the upper dividing cylinder 3 and the lower dividing cylinder 17 are integrated, side plates 4 are welded on both sides of the groove of the base 1, a pushing cylinder group 2 is installed on the inner side of one side plate 4, a butt opening 20 is opened on one side of the upper dividing cylinder 3, the end of the pushing cylinder group 2 is in contact with the butt opening 20, and they are adapted to each other, and the pushing cylinder group here includes a cylinder body and a cylinder column.

[0027] In this equipment, the entire tipping machine is mainly composed of an upper sub-cylinder 3 and a lower sub-cylinder 17. The lower sub-cylinder 17 is buried in a groove in the middle of the base 1. When the entire tipping machine assembly is turned over, the internal materials will be poured into the groove, and the transport vehicle will enter the tipping machine assembly along the track 11. It should be noted that the weight of the lower sub-cylinder 17 is heavier than that of the upper sub-cylinder 3, so the entire tipping machine assembly will not shake easily.

[0028] A hook 5 is welded to the top of the upper dividing cylinder 3, a pull rope 7 is connected to one side of the hook 5, an output shaft 9 is connected to the end of the pull rope 7, the pull rope 7 is wound around the surface of the output shaft 9, and a winding motor group 8 is transmission-connected to the end of the output shaft 9.

[0029] Tracks 11 are provided on both sides of the top of the lower sub-drum 17, and an infrared sensor 6 is installed in the middle of the top of the lower sub-drum 17. When a vehicle enters the dumper, the truck will block the infrared sensor 6, and the infrared sensor 6 will sense it quickly.

[0030] Downward-pressing cylinder assemblies 12 are installed on both sides of the top of the upper dividing cylinder 3, and the bottom end of the downward-pressing cylinder assembly 12 is threadedly connected with a clamp 13. Electric push rods 14 are installed on both sides of the clamp 13, and clamps 15 are installed at the ends of the electric push rods 14.

[0031] After the infrared sensor 6 senses that the vehicle has entered the tipping machine, it will transmit a signal to the control computer. The control computer will first transmit a command signal to the retracting motor group 8 and the pushing cylinder group 2. After receiving the signal, the pushing cylinder group 2 will control the cylinder column to extend forward. When the cylinder column extends forward, it will enter the stop 20 and then continue to extend forward. In the process of continuing to extend forward, the cylinder column will push the tipping machine in a clockwise direction. At the same time, after receiving the signal, the retracting motor group 8 will control the output shaft 9 to rotate counterclockwise. The counterclockwise rotation of the output shaft 9 will reel in the pull rope 7, and the tipping machine will be pulled to one side through the pull rope 7. It should be noted that the movable interface 16 on the front side of the lower sub-cylinder 17 is for connecting the motor-driven flipping assembly. This is an existing commonly used flipping drive method, which will not be explained in detail here. Through thrust, rotational force and pulling force, the tipping machine can be flipped faster, and the wear of the output shaft of the motor flipping assembly can be reduced.

[0032] An opening is provided on the side of the upper dividing cylinder 3, which is used for dumping materials. In the present device, when the car tipper drives the car to turn over, it only rotates between 45° and 60°, and the car will remain in an inclined state. Specific embodiment 2:

[0034] Reference Figure 1-6 A telescopic cylinder assembly 18 is installed in the middle of the top end of the upper sub-tube 3, and a vibration plate 19 is installed at the bottom end of the telescopic cylinder assembly 18.

[0035] The front and back sides of the bottom of one side of the upper dividing cylinder 3 are welded with embedded frames 10 , a groove is provided in the middle of the embedded frame 10 , and a servo motor group 21 is installed at the top of the embedded frame 10 .

[0036] The bottom end of the servo motor group 21 is drivingly connected to a driving shaft 22 , a turntable 23 is threadedly connected to the middle of the driving shaft 22 , a connecting arm 24 is threadedly connected to one side of the turntable 23 , and a sweeping plate 25 is welded to the end of the connecting arm 24 .

[0037] After the control computer transmits a signal to the push cylinder group 2 and the retracting motor group 8, it then transmits a signal to the downward pressing cylinder assembly 12. The cylinder downward pressing assembly 12 includes a cylinder body and a telescopic rod. After receiving the signal, the cylinder downward pressing assemblies 12 on both sides will control the telescopic rod at the bottom to descend, and the bottom clamp 13 will continue to descend to and Figure 6When the push rod 14 is pushed forward, it will drive the two side clamps 15 to move closer inward until the top of the car body is clamped. A pressure sensor is installed in the clamp 15. When the pressure sensor senses that the contact and extrusion pressure of the car body wall reaches a limit value, it will transmit a stop signal to the output end of the push rod 14 through the built-in MCU. Then the output end will control the push rod 14 to stop extending, so as to ensure that the clamp 15 can firmly clamp the car body. The weight of the clamp 13 itself is large, and when it is pressed down, it contacts the top of the car body and applies pressure. By cooperating with the clamping force of the clamp 15, the car body can be well limited.

[0038] After the tipping machine drives the car to rotate half of the groove on the base 1, it will stop rotating. At this time, the material in the car will flow out from the discharge port on the side of the upper dividing cylinder 3. After the car is tilted, the control computer will transmit a signal to the telescopic cylinder assembly 18. After receiving the signal, the telescopic cylinder assembly 18 will control the bottom cylinder shaft to descend and drive the vibration plate 19 to descend. A proximity sensor is also installed in the vibration plate 19. When it contacts the side wall of the car, it will quickly sense it. After sensing, it will transmit a signal to the power source of the vibration plate 19 through the built-in MCU. The vibration plate 19 here is the vibration device in the prior art. The power source will control the vibration of the vibration plate 19, and the high-frequency vibration can drive the vibration of the car surface wall. After the vibration, the speed of emptying the material inside will be faster.

[0039] Finally, the control computer will transmit a signal to the servo motor group 21. After receiving the signal, the servo motor group 21 will control the drive shaft 22 to drive the turntable 23. During the rotation of the turntable 23, the sweeping plate 5 at one end will sweep the goods in the compartment outward to prevent any residue on the box wall. Here, the rotation angle of the turntable 23 is limited, and it will only drive the sweeping plate 25 to swing left and right.

[0040] It should be noted that the control computer here is a control system. It is only the control end that sends commands and receives signals. It is not the core of this device, so it will not be explained in detail here.

[0041] In summary:

[0042] 1. After the infrared sensor 6 senses that the vehicle has entered the tipping machine, it will transmit a signal to the control computer. The control computer will first transmit a command signal to the retracting motor group 8 and the pushing cylinder group 2. After receiving the signal, the pushing cylinder group 2 will control the cylinder column to extend forward. When the cylinder column extends forward, it will enter the stop 20 and then continue to extend forward. In the process of continuing to extend forward, the cylinder column will push the tipping machine in the clockwise direction. At the same time, after receiving the signal, the retracting motor group 8 will control the output shaft 9 to rotate counterclockwise. The counterclockwise rotation of the output shaft 9 will reel in the pull rope 7, and the tipping machine will be pulled to one side by the pull rope 7. It should be noted that the movable interface 16 on the front side of the lower sub-cylinder 17 is for connecting the motor-driven flipping assembly. This is an existing commonly used flipping drive method, which will not be explained in detail here. Through thrust, rotational force and pulling force, the tipping machine can be flipped faster, and the wear of the output shaft of the motor flipping assembly can be reduced.

[0043] 2. After the control computer transmits a signal to the push cylinder group 2 and the retracting motor group 8, it then transmits a signal to the downward pressing cylinder assembly 12. The cylinder downward pressing assembly 12 includes a cylinder body and a telescopic rod. After receiving the signal, the cylinder downward pressing assemblies 12 on both sides will control the telescopic rod at the bottom to descend, and the bottom clamp 13 will continue to descend to and Figure 6 When the push rod 14 is pushed forward, it will drive the two side clamps 15 to move closer inward until the top of the car body is clamped. A pressure sensor is installed in the clamp 15. When the pressure sensor senses that the contact and extrusion pressure of the car body wall reaches a limit value, it will transmit a stop signal to the output end of the push rod 14 through the built-in MCU. Then the output end will control the push rod 14 to stop extending, so as to ensure that the clamp 15 can firmly clamp the car body. The weight of the clamp 13 itself is large, and when it is pressed down, it contacts the top of the car body and applies pressure. By cooperating with the clamping force of the clamp 15, the car body can be well limited.
