Description

Technical Field

[0001] The present invention relates to the technical field of assisted cage trucks, and in particular to an assisted cage truck with inclination sensing and infrared anti-collision functions. Background Art

[0002] Tobacco products in a tobacco logistics warehouse need to be stored and transferred to a truck for delivery to order customers after order sorting. Currently, the tool for storage and transfer is a cage truck.

[0003] Upon retrieval, a Chinese patent with the publication number CN213138830U discloses a tobacco transportation cage truck, which includes a bottom plate. Above the bottom plate is connected a U-shaped space surrounded by a rear cage plate, a left cage plate, and a right cage plate. A front cage door capable of opening or closing the U-shaped space is connected to the front side of the U-shaped space. The rear cage plate, the left cage plate, the right cage plate, and the front cage door all include a cage plate frame and a number of cage plate rods connected within the cage plate frame. A number of adjusting sliders are slidably connected to the cage plate rods of the left cage plate and the right cage plate. A slider top screw capable of restricting the up and down sliding of the adjusting slider is threadedly connected to the adjusting slider; a partition is connected to the top surface of the adjusting slider. In this patent, the height of each layer can be adjusted according to the actual height of cigarette cartons or cigarette packs, so that neither the bottom layer will be damaged by compression nor the situation of insufficient storage and mutual collision during transportation will occur.

[0004] However, the above invention has the following deficiencies:

[0005] [[ID=,17]]When the existing cage truck transports tobacco, due to the relatively high height of the cage truck, the center of gravity of the cage truck is on the high side. A high center of gravity easily causes the cage truck to tilt when moving. If the tilt reaches a certain angle, the cage truck will roll over under the action of inertia, resulting in damage to the internal tobacco, and it is relatively inconvenient to use.

[0021] The present invention provides a powered cage truck with inclination sensing and infrared anti-collision functions through improvements. Compared with the prior art, the following improvements and advantages are achieved:

[0022] First: The present invention is provided with an adaptive braking mechanism. Tobacco is placed between the upper bottom plate and the top plate. When the device tilts during movement, the upper bottom plate tilts to one side, and the level on the upper bottom plate will turn off the drive motor through the controller. Whichever side the upper bottom plate tilts towards will squeeze the second piston rod on this side. After being squeezed, the second piston rod will move towards the inside of the second air chamber, thereby squeezing the air inside the second air chamber. After being squeezed, the air will leave the inside of the second air chamber through the air pipe and then enter the inside of the first air chamber. When the air enters the first air chamber, the first piston rod will move downward under the action of air pressure. The downward movement of the first piston rod will squeeze the pressure plate, thereby driving the transmission sleeve to move downward through the pressure plate. Since the brake rod is bent, the downward movement of the transmission sleeve will squeeze the two brake rods. After being squeezed, the two brake rods will move towards each other, thereby driving the two brake blocks to move towards the brake pads. The two brake blocks clamp the brake pads, and at this time, the power shaft will stop rotating under the action of friction, thereby stopping the movement of the device, thus achieving the effect that when the device tilts during movement, it will automatically brake.

[0023] Second: The present invention is provided with a flywheel energy storage device, an infrared distance gauge, and an alarm. The flywheel energy storage device can accelerate the rotation of the flywheel inside it through the kinetic energy generated during the movement of the device. When the movement stops, the flywheel continues to store kinetic energy due to inertia and releases the stored energy when restarting, thereby reducing the force required to push the device when the drive motor is not started, facilitating the movement of the device; the infrared distance gauge can measure the distance to the surrounding area during the movement of the device. When the device is about to collide with an external object, the infrared distance gauge will start the alarm through the controller to issue a warning.

[0024] Third: The present invention is provided with an adjustment mechanism. By rotating the adjustment rod with the first knob, since the adjustment rod is threadedly connected to the transmission plate, the transmission plate will move up and down inside the adjustment seat, thereby driving the movable plate and the bearing plate to move up and down inside the upper bottom plate, thereby changing the space size between the multiple movable plates and the bearing plate, facilitating the loading of different quantities of tobacco. At the same time, after loading, the tobacco can be clamped by moving the bearing plate to prevent the tobacco from scattering.

[0025] Fourthly: Through the arrangement of the positioning mechanism, the other end of the bearing plate can be fixed on the positioning rod. When it is necessary to unload the tobacco, the knob two can be rotated. The knob two drives the drive shaft to rotate through the transmission bevel gear two. The rotation of the drive shaft causes the positioning block to move inside the installation groove, and then one end of the positioning block leaves the inside of the support groove. At this time, the bearing plate can be flipped. After the bearing plate is flipped downward, the tobacco on the bearing plate can slide down from the inclined surface of the bearing plate, which is convenient for unloading the tobacco.

[0039] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention are clearly and completely described. 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 belong to the scope of protection of the present invention.

[0040] The present invention provides a power-assisted cage cart with inclination sensing and infrared anti-collision functions through improvement. The technical solution of the present invention is as follows:

[0041] As Figures 1 to 8 shown, the embodiment of the present invention provides a power-assisted cage cart with inclination sensing and infrared anti-collision functions, including an upper base plate 1, a top plate 2 and a side cage 3. Both the upper base plate 1 and the top plate 2 are plates with a rectangular structure. The top plate 2 is arranged above the upper base plate 1. The side cage 3 is fixedly installed between the upper base plate 1 and the top plate 2. A lower base plate 4 is arranged below the upper base plate 1. The lower base plate 4 is a plate with a rectangular structure. A connecting mechanism is arranged between the upper base plate 1 and the lower base plate 4. Two universal wheels 5 are installed on one side of the bottom wall surface of the lower base plate 4, and two power wheels 6 are installed on the other side of the bottom of the lower base plate 4. A driving mechanism is arranged at the bottom of the lower base plate 4;

[0042] The driving mechanism includes a power box 7, a driving motor 8, a rotating shaft 9, a power shaft 10, and a first transmission bevel gear 11. The power box 7 is of a hollow rectangular structure and is fixedly installed on the bottom wall of the lower bottom plate 4 corresponding to the position of the power wheel 6. The driving motor 8 is fixedly installed inside the power box 7. The rotating shaft 9 is of a cylindrical structure and is installed between two power boxes 7, and one end of the rotating shaft 9 penetrates through the side wall of the power box 7 and is located inside the power box 7. The power shaft 10 is of a cylindrical structure and is fixedly installed on the output end of the driving motor 8. There are two first transmission bevel gears 11, and the two first transmission bevel gears 11 are respectively fixedly sleeved on the rotating shaft 9 and the power shaft 10, and the two first transmission bevel gears 11 mesh with each other. A spirit level is provided on the upper bottom plate 1, and the spirit level is electrically connected to the driving motor 8 through a controller. When the driving motor 8 is started, the driving motor 8 drives the power shaft 10 to rotate, and the power shaft 10 can drive the rotating shaft 9 to rotate through the first transmission bevel gear 11, so that the two power wheels 6 can rotate, facilitating the movement of the device. At the same time, the universal wheels 5 facilitate steering during movement;

[0043] A brake pad 12 is fixedly sleeved on the power shaft 10. The brake pad 12 is of a disc-shaped structure. An adaptive braking mechanism is provided between the lower bottom plate 4 and the power box 7. The adaptive braking mechanism includes a brake rod 13, a brake block 14, a transmission sleeve 15, a pressing plate 16, a first air chamber 17, a first piston rod 18, and a mounting spring 19. There are two brake rods 13 and two brake blocks 14. The two brake rods 13 are both movably installed on the bottom of the lower bottom plate 4 corresponding to the position of the brake pad 12. The brake rod 13 is provided with a crank structure. The brake block 14 is a rectangular block. The two brake blocks 14 are respectively arranged on both sides of the brake pad 12, and the two brake blocks 14 are respectively movably connected to the two brake rods 13 through torsion spring shafts. The transmission sleeve 15 is of a hollow rectangular structure and is movably sleeved above the two brake rods 13. The pressing plate 16 is a rectangular plate and is fixedly installed on the side wall surfaces of the transmission sleeve 15. There are two first air chambers 17, two first piston rods 18, and two mounting springs 19. The first air chamber 17 is of a hollow cylindrical structure and is embedded in the lower bottom plate 4. The first piston rod 18 is movably installed inside the first air chamber 17, and the bottom of the first piston rod 18 penetrates downward through the bottom of the first air chamber 17 and is in contact with the pressing plate 16. The mounting spring 19 is located inside the first air chamber 17 and is sleeved on the first piston rod 18;

[0044] The adaptive braking mechanism further includes a second air chamber 20, a second piston rod 21, an air pipe 22, a pneumatic valve 23 and a check valve 24. The second air chamber 20 is of a hollow cylindrical structure. There are two second air chambers 20 and two second piston rods 21. Both of the two second air chambers 20 are embedded and installed on the lower bottom plate 4. The second piston rod 21 is of a cylindrical structure. The second piston rod 21 is movably installed inside the second air chamber 20 and penetrates upward through the top of the second air chamber 20. The top of the second piston rod 21 is in contact with the bottom of the upper bottom plate 1. The air pipe 22 is of a tubular structure. The air pipe 22 is fixedly installed on the side wall of the second air chamber 20 and communicates with the inside of the second air chamber 20. The other ends of the air pipe 22 communicate with the inside of the two first air chambers 17 respectively. There are multiple pneumatic valves 23. The pneumatic valves 23 are fixedly installed at one end of the air pipe 22 corresponding to the first air chamber 17. The check valve 24 is embedded and installed at the bottom of the second air chamber 20. The check valve 24 allows external air to enter the inside of the second air chamber 20, and the air inside the second air chamber 20 cannot leave the inside of the second air chamber 20. Through the setting of the adaptive braking mechanism, the tobacco is placed between the upper bottom plate 1 and the top plate 2. When the device tilts during movement, the upper bottom plate 1 tilts to one side. The level on the upper bottom plate 1 will close the drive motor 8 through the controller. The upper bottom plate 1 will squeeze the second piston rod 21 on this side when it tilts to which side. After being squeezed, the second piston rod 21 will move towards the inside of the second air chamber 20, and then the air inside the second air chamber 20 can be squeezed. After the air is squeezed, it will leave the inside of the second air chamber 20 through the air pipe 22 and then enter the inside of the first air chamber 17. When the air enters the inside of the first air chamber 17, the first piston rod 18 will move downward under the action of air pressure. The downward movement of the first piston rod 18 will squeeze the pressing plate 16, so that the transmission sleeve 15 can be driven to move downward through the pressing plate 16. Since the brake rod 13 is bent, the downward movement of the transmission sleeve 15 will squeeze the two brake rods 13. After being squeezed, the two brake rods 13 will move towards each other, and then the two brake blocks 14 can be driven to move towards the brake pads 12. The two brake blocks 14 clamp the brake pads 12. At this time, the power shaft 10 will stop rotating under the action of friction, and then the device will stop moving, thus achieving the effect that the device will automatically brake when it tilts during movement.

[0045] A chute 25 is formed on the lower bottom plate 4. The chute 25 is a groove with a rectangular structure. The tops of the two brake rods 13 are both located inside the chute 25. A slide bar 26 is horizontally and fixedly installed inside the chute 25. The slide bar 26 is of a cylindrical structure. Both of the two brake rods 13 are slidably sleeved on the slide bar 26. An installation spring two 27 is sleeved on the slide bar 26. After being squeezed by the transmission sleeve 15, the brake rod 13 will move on the slide bar 26 and squeeze the installation spring two 27 at the same time. When the braking is completed, the installation spring two 27 will release elastic force to drive the brake rod 13 to reset.

[0046] As Figure 7As shown, the connecting mechanism includes a mounting base 28, a mounting rod 29, a connecting seat 30, a support rod 31 and a support spring 32.

The mounting rod 29 is of a cylindrical structure and is movably installed between the two mounting bases 28. There are two connecting seats 30, and the two connecting seats 30 are respectively fixedly installed on both sides of the bottom of the upper bottom plate 1. The two connecting seats 30 are both movably sleeved on the mounting rod 29. The support rod 31 is of a cylindrical structure, and there are multiple support rods 31. The multiple support rods 31 are all inlaid and movably installed on the lower bottom plate 4. The top of the support rod 31 is in contact with the upper bottom plate 1. The support spring 32 is sleeved on the support rod 31. The upper bottom plate 1 and the lower bottom plate 4 are movably connected through the connecting mechanism. When the upper bottom plate 1 tilts, the upper bottom plate 1 will squeeze a certain side of the support rod 31, and the support rod 31 will move on the lower bottom plate 4. At the same time, the upper bottom plate 1 will also squeeze the support spring 32 sleeved on the support rod 31. Under normal circumstances, the multiple support springs 32 support the upper bottom plate 1, making the upper bottom plate 1 in a horizontal state.

[0047] A flywheel energy storage device 33 is arranged at the bottom of the lower bottom plate 4. The flywheel energy storage device 33 is electrically connected to the drive motor 8. The flywheel energy storage device 33 can accelerate the rotation of the flywheel inside it through the kinetic energy generated when the device moves. When the movement stops, the flywheel continues to store kinetic energy due to inertia and releases the stored energy when restarted. Therefore, when the drive motor 8 is not started, the force required to push the device can be reduced, facilitating the movement of the device.

[0048] A plurality of infrared distance sensors 37 and alarms are installed on the side walls of the upper bottom plate 1 and the top plate 2. The infrared distance sensors 37 and the alarms are electrically connected through a controller. The infrared distance sensors 37 can measure the distance to the surrounding area when the device moves. When the device is about to collide with an external object, the infrared distance sensors 37 will activate the alarms through the controller to give a warning.

A plurality of movable plates 38 are arranged on the adjusting seat 39. The movable plates 38 are rectangular plates. A sliding sleeve 43 is installed on the movable plate 38. The sliding sleeve 43 is a hollow structure. The sliding sleeve 43 is movably sleeved on the side cage 3. A bearing plate 44 is movably installed on the movable plate 38 through a torsion spring shaft. The bearing plate 44 is a rectangular plate. Tobacco can be placed between the plurality of bearing plates 44. An adjusting mechanism is arranged inside the adjusting seat 39. The adjusting mechanism includes a transmission plate 40, an adjusting rod 41 and a first knob 42. The transmission plate 40 is a rectangular plate. The number of the transmission plates 40 and the adjusting rods 41 is the same as the number of the movable plates 38. The transmission plate 40 is arranged inside the adjusting seat 39. A plurality of transmission plates 40 are fixedly connected to a plurality of movable plates 38 respectively. The adjusting rod 41 is a cylindrical structure with threads. The adjusting rod 41 is movably installed inside the adjusting seat 39. And a plurality of adjusting rods 41 respectively penetrate through the upper and lower wall surfaces of a plurality of transmission plates 40 and are threadedly connected thereto. The first knob 42 is fixedly installed on the tops of the plurality of adjusting rods 41. By rotating the first knob 42 to adjust the adjusting rod 41, and the adjusting rod 41 is threadedly connected to the transmission plate 40, the transmission plate 40 will move up and down inside the adjusting seat 39, thereby driving the movable plate 38 and the bearing plate 44 to move up and down inside the upper bottom plate 1, and thus the space size between the plurality of movable plates 38 and the bearing plates 44 can be changed, which is convenient for loading different quantities of tobacco. At the same time, after loading, the tobacco can be clamped by moving the bearing plate 44 to prevent the tobacco from scattering.

[0051] A positioning mechanism is provided between the bearing plate 44 and the side cage 3. The positioning mechanism includes a positioning rod 45, a positioning block 48, a second knob 50, a drive shaft 51, and a second transmission bevel gear 52. The positioning rod 45 is a long rod with a rectangular structure. There are two positioning rods 45, and the two positioning rods 45 are respectively fixedly installed on both sides inside the side cage 3. A plurality of support grooves 46 are formed in the positioning rod 45. The support grooves 46 are grooves with a rectangular structure. Installation grooves 47 are formed in the bearing plate 44 at positions corresponding to the support grooves 46. The positioning block 48 is a rod with a rectangular structure. The positioning block 48 is movably installed inside the installation groove 47. One end of the positioning block 48 is located inside the support groove 46. A transmission groove 49 is formed in the middle position inside the bearing plate 44. The transmission groove 49 is a cylindrical groove. The second knob 50 is movably installed inside the transmission groove 49. The drive shaft 51 is a cylindrical structure with threads. The drive shaft 51 is movably installed between the installation groove 47 and the transmission groove 49, and one end of the drive shaft 51 is located inside the positioning block 48 and is threadedly connected to the positioning block 48. There are a plurality of second transmission bevel gears 52. The plurality of second transmission bevel gears 52 are respectively fixedly sleeved on the second knob 50 and the drive shaft 51. The second transmission bevel gear 52 on the second knob 50 meshes and drives with the second transmission bevel gear 52 on the drive shaft 51. Through the setting of the positioning mechanism, the other end of the bearing plate 44 can be fixed on the positioning rod 45. When it is necessary to unload tobacco, the second knob 50 can be rotated. The second knob 50 drives the drive shaft 51 to rotate through the second transmission bevel gear 52. The rotation of the drive shaft 51 causes the positioning block 48 to move inside the installation groove 47, and then one end of the positioning block 48 leaves the inside of the support groove 46. At this time, the bearing plate 44 can be flipped. After the bearing plate 44 is flipped downward, the tobacco on the bearing plate 44 can slide down from the inclined surface of the bearing plate 44, which is convenient for unloading the tobacco.

[0052] Specific implementation steps: Start the drive motor 8. The drive motor 8 drives the power shaft 10 to rotate. The power shaft 10 can drive the rotating shaft 9 to rotate through the first transmission bevel gear 11, and then the two power wheels 6 can be rotated, which is convenient for moving the device. At the same time, the universal wheels 5 are convenient for steering during movement.

[0053] An adaptive braking mechanism is also provided. The tobacco is placed between the upper bottom plate 1 and the top plate 2. When the device tilts during movement, the upper bottom plate 1 tilts to one side. The level on the upper bottom plate 1 will turn off the drive motor 8 through the controller. Whichever side the upper bottom plate 1 tilts to, the piston rod two 21 on this side will be squeezed. After being squeezed, the piston rod two 21 will move towards the inside of the air chamber two 20, and then the air inside the air chamber two 20 can be squeezed. After the air is squeezed, it will leave the inside of the air chamber two 20 through the air pipe 22 and then enter the inside of the air chamber one 17. When the air enters the inside of the air chamber one 17, the piston rod one 18 will move downward under the action of air pressure. The downward movement of the piston rod one 18 will squeeze the pressure plate 16, so that the transmission sleeve 15 can be driven downward by the pressure plate 16. Since the brake rod 13 is bent, the downward movement of the transmission sleeve 15 will squeeze the two brake rods 13. After being squeezed, the two brake rods 13 will move towards each other, and then the two brake pads 14 can be driven to move towards the brake disc 12. The two brake pads 14 clamp the brake disc 12. At this time, the power shaft 10 will stop rotating under the action of friction, and then the device will stop moving, thus achieving the effect that the device will automatically brake when it tilts during movement.
