Description

Technical Field

[0001] This invention relates to the field of production handling equipment technology, and in particular to a mobile drum tipping device. Background Technology

[0002] Before being put into production, barrelled liquid materials placed at the industrial production site must be handled by experienced personnel. Using one hand, they must hold the barrel at its top, tilting it towards their body, while the other hand supports the upper part of the barrel on its outside, continuously applying force away from their body to rotate and move the tilted barrel on the ground. Once the barrel reaches the feeding point, it is straightened and brought to a stable stop. The operator then unscrews the cap, aligns the barrel opening with the feed inlet of the feeding trough, tilts the barrel, and slowly lowers it until it is level. The liquid material inside the barrel continuously flows into the feeding trough from the opening.

[0003] This method presents the following problems: 1. The tilt angle of the bucket, the magnitude and direction of the force required for its movement are difficult to control, requiring high skill levels from the operators; 2. The speed at which the bucket moves depends on the speed of the operator's steps. Different operators have different physical strength and abilities, resulting in varying paces and bucket speeds, leading to inconsistent work efficiency and increased difficulty in managing tasks, quality, and operations; 3. During the tilting, moving, and reversing of the bucket, there is a risk of bucket tipping over and liquid splashing, posing safety and environmental hazards such as injury and site pollution.

[0004] To assist technicians in handling and pouring bottled liquids, existing technologies offer several handling aids, such as handcarts and handling robots. While handcarts can significantly reduce the physical effort required for manual handling of containers, loading and unloading still requires manual labor. For heavier containers, technicians sometimes lack the strength to lift or unload them. Handling robots, while capable of automatically performing tilting, moving, and emptying operations, are more expensive to purchase and maintain than handcarts. Furthermore, handling robots primarily rely on batteries to power their motors, and in environments with high temperatures, low temperatures, or high humidity, the stability of the batteries and motors can be compromised, significantly reducing operational safety. Summary of the Invention

[0005] To address the problems mentioned in the background section, the present invention provides a mobile bucket-tilting device.

[0014] Preferably, the pulley block includes a first take-up reel, a first pulley disc, and a first pulley cable. The first take-up reel is coaxially sleeved outside the fixed rotating shaft. The first pulley disc is closely connected to the moving block. One end of the first pulley cable is fixedly connected to the side of the hollow frame rod away from the moving block, and the other end is connected to the first take-up reel after passing around the first pulley disc.

[0015] Preferably, the push pulley block includes a second take-up reel, a second pulley disc, a second pulley cable, and a push rod.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figure 1-9 A mobile bucket-tipping device includes a frame 1, a bucket-tipping assembly 2, a drive assembly 3, a steering assembly 4, and a push-pull force-saving mechanism 5. The drive assembly 3 and the steering assembly 4 are respectively installed on the lower part of the frame 1. Technicians use the drive assembly 3 to drive the device to move and use the steering assembly 4 to control the device to change the direction of movement. The bucket-tipping assembly 2 is installed at the front of the frame 1. Technicians use the push-pull force-saving mechanism 5 to move the liquid bucket onto the bucket-tipping assembly 2 and can use the push-pull force-saving mechanism 5 to tip over the liquid bucket on the bucket-tipping assembly 2.

[0035] The frame 1 includes two bottom beams 11, two vertical beams 12, and a connecting beam 13. The vertical beams 12 are vertically fixedly installed in the middle of the bottom beams 11, and the two ends of the connecting beam 13 are fixedly connected to the two bottom beams 11 respectively. The connecting beam 13 divides the space between the two parallel bottom beams 11 into front and rear parts. The tipping bucket assembly 2 is located at the front of the connecting beam 13, and the drive assembly 3 is located at the rear of the connecting beam 13.

[0036] The drive assembly 3 includes a bent coupling 31 and a drive wheel 32. The bent coupling 31 has a pedal section 311, which is bent to form a convex and concave section in a horizontal "S" shape. A rotatable pedal 33 is attached to each of the convex and concave sections of the pedal section 311. A pair of flush connecting sections 312 are installed at both ends of the pedal section 311. The connecting sections 312 are coaxially connected to the drive wheel 32 and rotatably connected to the base beam 11. In this way, the bent coupling 31 is rotatably mounted between the base beams 11. When a technician steps on the pedals 33 with both feet, the bent coupling 31 can be driven to rotate, thereby driving the drive wheel 32 to rotate, causing the device to move forward or backward.

[0037] The steering assembly 4 includes a steering link 41, a steering handle 42, a steering swing arm 43, a driven swing arm 44, and two sets of steering wheel sets 45. The steering link 41 is vertically mounted on the connecting beam 13 and can be axially rotatably mounted. The steering handle 42 is mounted on the upper end of the steering link 41. When the technician steps on the pedal 33 with both feet, he can hold the steering handle 42 with both hands to drive the steering link 41 to rotate axially.

[0038] Two sets of steering wheel assemblies 45 are respectively fixedly mounted on two base beams 11. Each steering wheel assembly 45 includes a fixed base 451, a mounting wheel 452, and a pusher 453. The fixed base 451 is fixedly connected to the base beam 11. The mounting wheel 452 is pivotally connected to the lower part of the fixed base 451. The pusher 453 is mounted on the outside of the mounting wheel 452. The two ends of the driven swing arm 44 are respectively connected to the pivots of the pushers 453 of the two sets of steering wheel assemblies 45. One end of the steering swing arm 43 is fixedly connected to the steering linkage 41, and the other end is pivotally connected to the middle position of the driven swing arm 44. When the technician drives the steering linkage 41 to rotate axially, the steering swing arm 43 will also drive the driven swing arm 44 to swing. When the driven swing arm 44 swings, it can push the mounting wheel 452 to deflect, thereby changing the orientation of the mounting wheel 452 and thus adjusting the movement direction of the device.

[0039] It is worth mentioning that the length of the steering arm 43 can be changed to adaptively adjust its length according to the swing amplitude of itself and the driven arm 44, thereby driving the frame wheel 452 to turn smoothly.

[0040] The tipping assembly 2 includes a guide ramp 21, a placement plate 22, and a tipping device 23. The guide ramp 21 and the placement plate 22 are fixedly installed at the front of the connecting beam 13. The front of the guide ramp 21 has an inclined slope, with the front end of the slope extending downward and close to the ground. The rear end of the guide ramp 21 is transitionally connected to the upper surface of the placement plate 22 so that the front of the guide ramp 21 can scoop up the bottom of the liquid bucket. Technicians can use the push-pull force-saving mechanism 5 to pull the liquid bucket along the guide ramp 21 toward the placement plate 22 and finally pull the liquid bucket onto the upper surface of the placement plate 22 for subsequent transportation operations.

[0041] The upper surface of the placement plate 22 has at least two symmetrically arranged placement grooves 201, which extend from the connecting beam 13 toward the guide slope block 21. Each placement groove 201 is equipped with a bucket-tilting device 23. The bucket-tilting device 23 includes a tilting plate 231 and a damper 232. The damper 232 is pivotally connected to one end of the tilting plate 231 facing the guide slope block 21 and is fixedly installed inside the placement groove 201. The tilting plate 231 can be axially tilted to tilt the liquid bucket placed on the placement plate 22. During the tilting process, the damper 232 provides a certain resistance to the tilting plate 231 to prevent the tilting plate 231 from tilting too fast and throwing the liquid bucket off.

[0042] At least two limiting rods 6 are detachably installed on the side of the vertical beam 12. Each limiting rod 6 includes a main rod body 61, a positioning element 62, a movable limiting block 63, and a locking screw 64. The upper part of the main rod body 61 has a vertically extending adjusting rail 601. The adjusting rail 601 is recessed into the limiting rod 6 and has a bottom wall 602 and a side wall 603. The bottom wall 602 has a plurality of axial limiting slots 604 arranged at equal intervals in the setting direction. The side wall 603 has a limiting screw hole 605 through each axial limiting slot 604.

[0043] The movable limiting block 63 includes an outer protrusion 631 and a docking plug 632. The docking plug 632 can be inserted into the axial limiting socket 604. The outer protrusion 631 can be inserted into the adjusting rail 601 with the docking plug 632 facing the axial limiting socket 604. After the docking plug 632 is inserted into the limiting socket 604, the outer protrusion 631 partially protrudes out of the adjusting rail 601. The outer protrusion 631 is provided with a screw insertion hole 6301. The locking screw 64 can pass through the limiting screw hole 605 and the screw insertion hole 6301 in sequence and be threaded onto the main rod body 61, thereby positioning the movable limiting block 63.

[0044] The positioning component 62 includes a linkage plate 621, a pressing protrusion 622, a positioning block 623, and a spring 624. The pressing protrusion 622 and the positioning block 623 are respectively installed at the upper and lower ends of the linkage plate 621. The lower end of the main rod body 61 has a setting cavity 606. The upper and lower ends of the setting cavity 606 have openings leading to the outside. The positioning component 62 is vertically installed in the setting cavity 606, and the pressing protrusion 622 and the positioning block 623 extend out of the openings of the setting cavity 606. The spring 624 is installed in the setting cavity 606 and pushes the linkage plate 621 away from the outside of the setting cavity 606 under normal conditions.

[0045] An insertion groove 2301 is provided on the upper surface of the flip plate 231 near the guide slope block 21. After the liquid tank is placed on the placement plate 22, the technician can remove the limiting rod 6 and squeeze the pressing protrusion 622 so that the pressing protrusion 622 and the positioning block 623 are retracted into the setting cavity 606. At this time, the lower end of the limiting rod 6 is inserted into the insertion groove 2301. The inner wall of the insertion groove 2301 has a positioning slot 2302 that allows the positioning block 623 to be inserted. After the lower end of the limiting rod 6 is inserted into the insertion groove 2301, the technician no longer squeezes the pressing protrusion 622. The spring 624 pushes the positioning block 623 into the positioning slot 2302 so that the limiting rod 6 is vertically positioned and installed on the flip plate 231.

[0046] After the limiting rod 6 is installed on the flipping plate 231, it can flip together with the flipping plate 231. At this time, the liquid tank is located behind the limiting rod 6. When the flipping plate 231 tilts the liquid tank to a certain angle, the liquid tank will tip over. When the liquid tank tip over, it can push the limiting rod 6 and rotate the flipping plate 231 until it flattens itself. During this process, the resistance provided by the damper 232 to the flipping plate 231 can be transmitted to the limiting rod 6, thereby preventing the liquid tank from tipping over too quickly and detaching from the device, causing an accident.

[0047] It is worth mentioning that after the limiting rod 6 is fixedly installed on the flip plate 231, the technician can install the movable limiting block 63 facing the liquid tank at a suitable height so that the bottom of the movable limiting block 63 is above the top surface of the liquid tank. After the liquid tank is laid down horizontally, it will continue to move horizontally under the action of inertia. The movable limiting block 63 can effectively block the liquid tank and prevent the liquid tank from moving horizontally and falling off the device, causing an accident.

[0048] The push-pull force-saving mechanism 5 includes a hollow frame rod 51, a moving block 52, a rotating component 53, a pulling pulley block 54, and a pushing pulley block 55. A hollow frame rod 51 is horizontally mounted on each of the two vertical beams 12. The front end of each hollow frame rod 51 is open to allow the moving block 52 to be inserted precisely into it. The rotating component 53 is mounted on the hollow frame rod 51 and allows technicians to rotate it simultaneously with both hands. The pulling pulley block 54 and the pushing pulley block 55 are respectively installed inside the hollow frame rod 51 and connected to the moving block 52. The rotating component 53 can drive the pulling pulley block 54 and the pushing pulley block 55 to rotate, thereby driving the moving block 52 to move horizontally.

[0049] Specifically, the rotating assembly 53 includes a rotating handle 531, a fixed rotating shaft 532, a switching device 533, and a docking head 534. The fixed rotating shaft 532 passes through the upper plate of the hollow frame rod 51 and extends into the interior of the hollow frame rod 51. The docking head 534 is installed on the outer peripheral wall of the portion of the fixed rotating shaft 532 that extends into the hollow frame rod 51.

[0050] The upper end of the fixed rotating shaft 532 passes through the upper plate of the hollow frame rod 51 and is coaxially connected to the rotating handle 531. Technicians use the rotating handle 531 to drive the fixed rotating shaft 532 to rotate axially. The switching device 533 is fixedly installed on the upper plate of the hollow frame rod 51 and is sleeved on the outside of the fixed rotating shaft 532.

[0051] The switching device 533 includes a ring sleeve 5331, a limiting post 5332, an outer rotating sleeve 5333, and a linkage bearing 5334. The linkage bearing 5334 is sleeved on the outside of the fixed rotating shaft 532, and the inner wall of the linkage bearing 5334 is integrally connected to the outer circumferential surface of the fixed rotating shaft 532. The ring sleeve 5331 is fixedly installed on the outside of the fixed rotating shaft 532. The limiting post 5332 is fixedly installed on the ring sleeve 5331 and passes through the outer ring of the linkage bearing 5334 to prevent the outer ring of the linkage bearing 5334 from rotating. The outer rotating sleeve 5333 meshes with the threaded outer ring of the linkage bearing 5334. Technicians can adjust the vertical position of the linkage bearing 5334 by rotating the outer rotating sleeve 5333 and using the meshing of the linkage bearing 5334 with the outer rotating sleeve 5333, thereby adjusting the vertical position of the fixed rotating shaft 532 and the docking head 534.

[0052] The pulley assembly 54 includes a first take-up reel 541, a first pulley disc 542, and a first pulley cable 543. The first take-up reel 541 is coaxially sleeved outside a fixed rotating shaft 532, which confines the first take-up reel 541 to a specified vertical position. The first take-up reel 541 can rotate freely axially outside the fixed rotating shaft 532. The first pulley disc 542 is closely connected to a movable block 52. One end of the first pulley cable 543 is fixedly connected to the side of the hollow frame rod 51 away from the movable block 52, and the other end is connected to the first take-up reel 541 after passing over the first pulley disc 542, thus forming a movable pulley structure. The push pulley assembly 55 includes a second take-up reel 551, a second pulley disc 552, a second pulley cable 553, and a push rod 554. The second take-up reel 551... 51 is coaxially sleeved outside the fixed rotating shaft 532. The fixed rotating shaft 532 limits the second take-up reel 551 to a specified vertical position. The second take-up reel 551 can rotate freely axially outside the fixed rotating shaft 532. The second pulley 552 is located on the side of the fixed rotating shaft 532 away from the moving block 52. The push rod 554 avoids the fixed rotating shaft 532 and connects the moving block 52 and the second pulley 552 so that when the second pulley 552 moves toward the moving block 52, it can push the moving block 52 out of the hollow frame rod 51. A positioning plate 56 is installed on the side of the fixed rotating shaft 532 away from the moving block 52. One end of the second pulley cable 553 is fixedly connected to the positioning plate 56. After passing around the second pulley 552, the other end is connected to the second take-up reel 551 to form a movable pulley structure.

[0053] Both the first take-up reel 541 and the second take-up reel 551 have mating grooves 501 on their opposite sides. The mating head 534 can be engaged into the mating grooves 501 of the first take-up reel 541 and the second take-up reel 551, thereby driving the first take-up reel 541 and the second take-up reel 551 to rotate when the fixed shaft 532 rotates. Technicians can adjust the vertical position of the fixed shaft 532 as needed using the switching device 533, so that the mating head 534 can be engaged into the first take-up reel 541 or the second take-up reel 551.

[0054] Understandably, the rotation of the first take-up reel 541 can drive the first pulley 542 to move toward the fixed pivot 532, thereby making it easier to pull the moving block 52 into the hollow frame rod 51; if the rotation of the second take-up reel 551 can drive the second pulley 552 to move toward the moving block 52, thereby making it easier to push the moving block 52 out of the hollow frame rod 51.

[0055] Reference Figure 10 and Figure 11The portion of the movable block 52 extending out of the hollow frame rod 51 has an opening. After the guide ramp 21 scoops up the liquid tank, the technician can use the opening of the movable block 52 to attach the two ends of the strap to the protruding ends of the two movable blocks 52. At this time, the operator adjusts the rotating component 53 to make the docking head 534 drive the first take-up reel 541 to rotate, which can drive the movable block 52 to pull the strap towards the placement plate 22 until the liquid tank is pulled onto the placement plate 22. When it is necessary to tip the tank for unloading, the strap is reversed to the side of the liquid tank away from the guide ramp 21. At this time, the operator adjusts the rotating component 53 to make the docking head 534 drive the second take-up reel 551 to rotate, which can drive the movable block 52 to push the strap towards the guide ramp 21, thereby tipping the liquid tank over.
