Description

Technical Field

[0001] This invention relates to the field of transportation equipment technology, specifically to a safety loading device for diethylene glycol methyl ether tank trucks. Background Technology

[0002] Diethylene glycol methyl ethyl ether (DME), a commonly used chemical raw material, is mostly stored and transported in drum form, requiring large-scale transfer by tank truck. Currently, the loading process of existing DME drums largely relies on manual handling from the factory or simple mechanical assistance, which has many technical shortcomings. (1) Manual handling is not only labor-intensive and inefficient, but also has certain chemical properties. Direct contact or improper operation can easily lead to safety risks (such as leakage, corrosion, etc.). (2) Traditional auxiliary machinery lacks a dedicated clamping structure, has poor adaptability to barrels of different specifications, and is prone to slipping and shaking during clamping, which can cause the barrels to tilt or even fall, posing a great safety hazard. (3) Existing handling equipment mostly uses force to clamp the barrel and then lift and transfer it. Since chemical products are mostly loaded in plastic barrels to prevent corrosion and reaction, the barrels have low strength and are easily deformed or broken by clamping force. In particular, larger barrels that contain more liquid are extremely difficult to clamp and lift. Summary of the Invention

A movable opening is formed in the middle of the other end of the clamping seat.

[0011] Preferably, the vehicle body is fastened to the other end of the first connecting arm or the other end of the second connecting arm via a clip, and moves by means of the first slide rail.

[0012] The beneficial effects are as follows: The diethylene glycol methyl ethyl ether tanker safety loading device proposed in this invention achieves symmetrical linear force clamping through an adjustable clamping unit. For barrels with straight sidewalls, the second clamping rod in the clamping unit rotates to form a V-shape, clamping barrels with curved walls (cylindrical barrels), thus effectively applying uniform force. Utilizing the clamping unit's fit to the barrel's sidewall for limiting movement, and with the cooperation of the swing unit and drive unit, force is applied to the barrel near the top, causing it to tilt and flip to the left. This raises the right side of the barrel's bottom, creating space where the right-side pushing unit can be driven by the first slide rail of the main structure to insert the left end of the vehicle body into the right end of the barrel. By using the swing unit to tilt and flip to the right, the bottom left end of the bucket is raised, and the bottom right end of the bucket is now on the right-side carriage. The left-side carriage is then moved to the right and inserted into the bottom left end of the bucket. The swing unit and clamping unit then straighten the bucket, placing its bottom on both carriages. Depending on the needs, the two carriages can be moved in the same direction to transfer the raised bucket to one of them. Finally, the universal wheels are used to detach the pushing unit from the main structure for hand-pushing transport. The height of the clamping unit can be adjusted according to the bucket's height; a higher clamping unit during the bucket's left-right swing requires less effort. In summary, the following effects can be achieved: 1. The clamping unit, through its adjustable design, can achieve symmetrical linear force application to fit barrels with straight side walls, and can also form a V-shaped structure through the relative flipping of the second clamping rod to adapt to barrels with curved walls, making it compatible with barrels of different shapes; at the same time, it supports adjusting the position of the clamping unit according to the height of the barrel, further expanding the scope of application, and eliminating the need to configure separate equipment for barrels of different specifications.

[0013] 2. The clamping unit, through its uniform force application and limiting design that fits the side wall of the barrel, can effectively prevent the barrel from slipping, shaking, or experiencing uneven force during operation, reducing the risk of barrel tilting, falling, and leakage. The entire process replaces direct manual contact with mechanical operation, reducing the chance of personnel coming into contact with diethylene glycol methyl ether and further ensuring operational safety.

[0014] 3. By leveraging the cooperation of the swing unit and the drive unit, the precise docking of the pushing unit and the bucket is achieved through step-by-step flipping and tilting of the bucket, allowing the bucket to smoothly transition onto the pushing unit, with smooth connections between each step; the pushing unit can be detached from the main structure and moved independently by universal wheels, adapting to the entire process from clamping to transfer, improving the flexibility and efficiency of loading operations, and thus enabling one machine to be used on multiple vehicles.

[0015] 4. The height of the clamping unit is adjustable, and the higher the position, the less effort is required to operate, reducing mechanical drive energy consumption and manual intervention costs; the entire transfer process is automated and step-by-step through mechanical structure, which greatly reduces the labor intensity of manual handling and improves the comfort of operation.

Drive unit 2 includes a first pusher 21, a bearing 22, a controller 23, a hydraulic cylinder body 24, a rack 25, and a connecting rod 26. One end of the first pusher 21 is fixedly mounted on the bracket 12 and fits into the bracket 12. A sliding groove 6 is formed through the front side wall of one end of the first pusher 21. The other end of the first pusher 21 is concave. The bearing 22 is fixedly embedded in the middle of one end of the first pusher 21 and is located above the sliding groove 6. The controller 23 is fixedly mounted on the upper wall of one end of the first pusher 21. One end of the hydraulic cylinder body 24 is fixedly mounted on the front side arm of one end of the first pusher 21 and is located at the right end. The hydraulic cylinder body 24 is located above the bearing 22. The rack 25 is movably embedded in the sliding groove 6. One end of the connecting rod 26 is fixedly mounted on the... One end of the rack 25 and the other end of the connecting rod 26 are connected to the telescopic end of the hydraulic cylinder body 24. The main structure 1 is moved by the force applied by the first pusher 21. The hydraulic cylinder body 24 can be started by the controller 23. The extension and retraction of the hydraulic cylinder body 24 drives the rack 25 to move in the sliding groove 6. Then, the rack 25 and the gear 34 mesh to drive the swing unit 3 to swing back and forth. The drive unit 2 achieves stable power output through hydraulic transmission. The rack 25 and gear 34 transmission mechanism convert linear motion into rotational motion. It has the characteristics of high transmission accuracy, strong load capacity and smooth operation. It can accurately control the swing angle and speed of the swing unit 3, and provide reliable power guarantee for the tilting and subsequent transfer of the barrel.

[0022] like Figure 4 and Figure 5As shown, further, the swing unit 3 includes a rotating base 31, a shaft tube 32, a wheel axle 33, a gear 34, a second slide rail 35, and a pair of third slide rails 36. The rotating base 31 is movably disposed on the rear side of the first push frame 21. One end of the shaft tube 32 is fixedly disposed in the middle of the front side wall of the rotating base 31, and the shaft tube 32 is fixedly passed through the middle of the bearing 22. One end of the wheel axle 33 is fixedly disposed in the middle of the front side wall of the rotating base 31, and one end of the wheel axle 33 is inserted into the middle of the shaft tube 32. The other end of the wheel axle 33 is located in front of one end of the first push frame 21. The gear 34 is fixedly mounted on the wheel axle 33, and the gear 34 meshes with the rack 25. The second slide rail 35 is fixedly disposed in the middle of the rear side wall of the rotating base 31, and a relatively movable second moving seat is symmetrically disposed on the second slide rail 35. A pair of third slide rails 36 are respectively symmetrically disposed on the second slide rail 35. The second movable seat is mounted on the second slide rail 35, with the third slide rail 36 perpendicular to the second slide rail 35. The gear 34 meshes with the rack 25, and the axle 33 drives the rotating seat 31. The rotating seat 31 rotates on the bearing 22 via the shaft tube 32. The relative distance between the third slide rail 36 is adjusted via the second slide rail 35, and the height of the clamping unit 4 is adjusted via the third slide rail 36 to accommodate different bucket heights. By adjusting the second movable seat on the second slide rail 35, the distance between the pair of third slide rails 36 can be changed to accommodate buckets of different diameters or widths. By adjusting the third movable seat on the third slide rail 36, the height position of the clamping unit 4 can be changed to accommodate buckets of different heights, ensuring that the clamping point is always located in a stable force-bearing position on the bucket. When the clamping unit 4 is higher, the torque required to flip the bucket is smaller, making operation easier.

[0023] like Figure 6As shown, further, the clamping unit 4 includes a clamping base 41, an adjusting screw 42, an adjusting seat 43, a first clamping rod 44, a second clamping rod 45, and a pair of third clamping rods 46; the clamping base 41 is L-shaped, with one end of the clamping base 41 fixedly mounted on the third slide rail 36, and the other end of the clamping base 41 being longer than one end of the clamping base 41. A movable opening 7 is provided in the middle of the other end of the clamping base 41, and the two ends of the adjusting screw 42 respectively movably penetrate the front and rear side walls of the movable opening 7 and are located in the middle of the movable opening 7. The adjusting seat... One end of the adjusting seat 43 is movably inserted into the movable port 7, and one end of the adjusting seat 43 is movably screwed onto the adjusting screw 42. The other end of the adjusting seat 43 corresponds to one end of the clamp 41, and the upper wall of the other end of the adjusting seat 43 is on the same horizontal plane as the upper wall of one end of the clamp 41. One end of the first clamping rod 44 is fixedly set on the other end of the adjusting seat 43, and one end of the second clamping rod 45 is fixedly set on the upper wall of one end of the clamp 41, and the second clamping rod 45 is opposite to the first clamping rod 44, and the second clamping rod 45 is located at the first clamping rod 44. At the other end, one end of a pair of third clamping rods 46 is movably mounted on the lower wall of the other end of the first clamping rod 44 and the upper wall of the other end of the second clamping rod 45, respectively. The other ends of the pair of third clamping rods 46 are staggered vertically and are movably connected relative to each other. By rotating the adjusting screw 42, the adjusting seat 43 is moved within the moving port 7, causing the first clamping rod 44 to move relative to the second clamping rod 45 and adjust the spacing. As the spacing between the first clamping rod 44 and the second clamping rod 45 changes, the third clamping rod 46 is horizontally connected to the first clamping rod 44 and the second clamping rod 45, forming a straight splice or a V-shape, to fit the clamping of barrels with different side walls. The clamping unit 4 achieves adjustable spacing through thread adjustment, forming a multi-form clamping structure with the foldable third clamping rod 46. It can adapt to barrels with straight side walls and is compatible with round barrels with curved walls. The clamping force is uniform and the stability is high during the clamping process, providing a reliable guarantee for the safe transfer of barrels of different specifications.

[0024] like Figure 7As shown, further, the pushing unit 5 includes a vehicle body 51, two pairs of omnidirectional wheels 52, a pair of second handrails 53, and a bracket 54; the vehicle body 51 can be positioned above both ends of the wheel seat 11, the two pairs of omnidirectional wheels 52 are symmetrically arranged on the lower wall of the vehicle body 51 and located at the four corners, one end of each pair of second handrails 53 is fixedly installed on the upper wall of one end of the vehicle body 51 and they are symmetrical to each other, both of the second handrails 53 are L-shaped, and the bracket 54 is fixedly installed on the lower wall of one end of the vehicle body 51; by applying force through the second handrails 53 to push the vehicle body 51, the vehicle body 51 moves using the omnidirectional wheels 52, and by the movement of the vehicle body 51, it is positioned laterally above one end of the wheel seat 11, and the bracket 54 is fitted onto the first joint. When the boom 16 reaches its upper limit, the first connecting boom 16 can be driven by the first slide rail 15 to move the pushing unit 5. The vehicle body 51 is fastened to the other end of the first connecting boom 16 or the other end of the second connecting boom 17 via the bracket 54, and moves with the help of the first slide rail 15. This is designed to meet the linkage requirements and achieve detachable operation. The pushing unit 5 achieves flexible cooperation with the main structure 1 through modular design. The universal wheels 52 ensure the flexibility of movement, and the bracket 54 structure ensures a stable connection with the connecting boom. This not only meets the collaborative requirements of automated loading, but also retains the convenience of manual operation, effectively improving the adaptability and efficiency of the loading process.

[0025] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0026] First, the main structure 1 serves as the basic load-bearing unit. The equipment is moved as a whole by applying force through the first pusher 21 in the drive unit 2 and the rollers 13 at the bottom of the wheel seat 11. The wheel seat 11 is positioned at the bucket, and the bucket is positioned between the two ends of the wheel seat 11. The battery box 14 provides power to the entire device (such as hydraulic cylinders, slide rail drive components, etc.). Secondly, the clamping unit 4 is adapted to clamp the barrel: Clamping configuration adjustment: Based on the shape of the barrel side wall (straight or curved), rotate the adjusting screw 42 of the clamping unit 4 to drive the adjusting seat 43 to move along the moving port 7 of the clamping seat 41, thereby causing the first clamping rod 44 to move closer to or further away from the second clamping rod 45. For barrel components with straight side walls: the distance between the first clamping rod 44 and the second clamping rod 45 is adjusted to a suitable width, and a pair of third clamping rods 46 unfold under the action of tension, forming a "one-line" planar clamping structure with the first clamping rod 44 and the second clamping rod 45, which fits against the straight side wall to achieve uniform force application; For cylindrical barrels with curved walls: reduce the distance between the first clamping rod 44 and the second clamping rod 45, and the third clamping rod 46 flips relative to each other under the action of thrust to form a "V" angle. The symmetrical arrangement achieves four-point positioning to fit the curved wall, ensuring stable clamping.

[0027] Adapt to the height and spacing of the barrels: The relative spacing of a pair of third slide rails 36 is adjusted by the second slide rail 35 of the swing unit 3 to adapt to barrels of different widths / diameters; The height of the clamping unit 4 is adjusted by the third slide rail 36 so that the clamping point is located in a stable force-bearing position of the barrel (the higher the position, the less effort is required for subsequent flipping).

[0028] After clamping and adjustment are completed, the first clamping rod 44, the second clamping rod 45 and the third clamping rod 46 of the clamping unit 4 work together to fix the barrel. Before the barrel is flipped, the barrel is placed on the ground. At this time, the clamping unit 4 can have a certain reserved space with the side wall of the barrel, which is convenient for the barrel to be flipped. Then, the swing unit 3 is activated and the barrel tilt is adjusted; Swinging power transmission: Drive unit 2 starts hydraulic cylinder body 24 through controller 23 above bracket 12 and located on first push frame 21. The piston rod of hydraulic cylinder body 24 extends and retracts, and drives rack 25 to reciprocate along sliding groove 6 of first push frame 21 through linkage rod 26. Rack 25 meshes with gear 34 of swing unit 3, driving gear 34 and wheel axle 33 to rotate, thereby driving rotary seat 31 to rotate around bearing 22 as the center, and using shaft tube 32 connected to bearing 22 to achieve reciprocating swing. The details explain how the barrel is raised onto the pushing unit 5 through the cooperation of the main structure 1, the drive unit 2, and the swing unit 3; Step 1: The rotating seat 31 drives the clamping unit 4 and the barrel to tilt to the left, raising the right side of the bottom of the barrel to form an operating space; at this time, the right push unit 5 is fastened to the second linkage arm 17 of the main structure 1 through the card holder 54, and the second linkage arm 17 is driven to move by the first slide rail 15, so that the left end of the push unit 5's body 51 is accurately inserted into the right side of the bottom of the barrel, and the visual recognition camera 18 on the right side is used to image and determine whether the insertion is stable, that is, the body 51 moves through the universal wheel 52; Step 2: The rotating seat 31 drives the barrel to flip and tilt to the right, raising the bottom left side of the barrel. At this time, the right end of the barrel is on the right side of the vehicle body 51. The left push unit 5 is driven by the first connecting arm 16 and the first slide rail 15 to insert into the bottom left side of the barrel in the same way. At the same time, the left visual recognition camera 18 is used to determine whether the load has been completed. Step 3: The rotating seat 31 returns to its original position, which drives the clamping unit 4 to straighten the barrel, so that the bottom of the barrel falls steadily on the vehicle body 51 of the two pushing units 5. The fourth step is to transfer the barrel. According to the transfer requirements, the two pushing units 5 are driven to move in the same direction by the first slide rail 15. The barrel is moved onto one of the vehicle bodies 51 by the limiting of the clamping unit 4. The operator holds the second handle 53 of the pushing unit 5 and uses the universal wheel 52 to push the vehicle body 51. The card holder 54 is moved to the other end of the first connecting arm 16 or the second connecting arm 17 to the disengaged state, so that it can be separated from the main structure 1 and pushed to the side of the tank truck.

[0029] In summary, this solution achieves safe and efficient transfer of barrels of different specifications through a series of actions including clamping and fitting, swinging and tilting, pushing and docking, and transfer and loading. Combined with the adjustability of each unit (clamping shape, height, and spacing), the entire process is mechanical, reducing manual intervention, safety risks, and labor intensity.

[0030] The core advantages of this solution lie in its adaptability to various container types, automated mechanical operation, and safe and efficient transfer. Its structural design has strong versatility, and in addition to diethylene glycol methyl ether drums, it can be widely used for handling and transfer needs in the following scenarios: In chemical production, large quantities of liquid raw materials (such as organic solvents like methanol, ethanol, and acetone, acid and alkali solutions like sulfuric acid and sodium hydroxide, as well as resins and coating intermediates) are typically packaged in metal drums, plastic drums, or medium-sized storage tanks. These containers present the following challenges in transportation: they are made of diverse materials, have varying shapes (cylindrical, square), and some are corrosive or toxic, making manual handling prone to risks such as leaks and contact injuries.

[0031] The universal wheel design and detachable docking function of the push unit in this solution enable the entire transfer from the warehouse shelf to the tank truck / reactor inlet, reducing direct contact between humans and chemicals and lowering the risk of corrosion and poisoning. This solution can also be used for the storage and transportation of oil and fuel products. Oil products such as gasoline, diesel, lubricating oil, and hydraulic oil are mostly stored in sealed metal drums (to prevent leakage) or plastic drums.

[0032] When the third clamping rod of the clamping unit of this solution forms a "V-shape" clamping, the contact area with the arc-shaped wall of the metal bucket is large. Combined with the anti-slip rubber pad (which can be added), it can prevent slippage and ensure stable clamping of the heavy bucket. The swing unit is driven by a hydraulic cylinder to achieve slow tilting, which can precisely control the angle of the barrel, making it easy to pour oil from the barrel into the storage tank or equipment.

[0033] This solution can also be used for raw material / finished product transfer in the food and pharmaceutical industries. In the food industry, edible oils, syrups, sauces, etc., are often transported in stainless steel containers or food-grade plastic containers; in the pharmaceutical industry, pharmaceutical alcohol, pharmaceutical intermediates, etc., are mostly transported in sealed glass jars or corrosion-resistant plastic containers. The core requirements for transfer in these scenarios are hygiene and cleanliness (to avoid contamination) and no violent collisions (to prevent container breakage).

[0034] This solution can also be used for the transportation of coatings / adhesives in the construction and building materials industry. In construction, latex paint, waterproof coatings, structural adhesives, etc., are often transported in round iron drums or square plastic drums. These containers often have viscous residues, the sides are slippery, and some coatings contain volatile harmful components (such as formaldehyde and benzene compounds). Manual handling not only makes them easy to slip from the hands, but may also affect health due to inhalation of volatile substances.

[0035] Therefore, this solution can realize the handling and transfer of barrels in different fields; and for lighter goods, the visual recognition camera 18 can be used to image and determine the position for direct clamping, lifting and placing on the vehicle body of the pushing unit, and the stacking of goods can be achieved by using the height adjustment and visual recognition camera 18 to determine the position.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
