Description

Technical Field

[0001] This utility model belongs to the field of refueling trucks, and specifically relates to a refueling truck structural assembly. Background Technology

[0002] During aviation ground support, port crane maintenance, mining transport vehicle maintenance, and large construction machinery overhaul, key components such as gearboxes and hydraulic systems need to be regularly lubricated with oil or grease.

[0003] Traditional refueling methods often involve manually handling oil drums and injecting the oil into the equipment's oil inlet by tilting or manually pumping. This method has many drawbacks:

[0004] 1. High labor intensity and high safety risks: A fully loaded 200L lubricating oil steel drum can weigh more than 200kg. Manual handling can easily cause muscle strain, slipping, crushing injuries and other safety accidents to the operators, especially in high-altitude, narrow or slippery working environments. In addition, when tilting the oil drum, if not properly controlled, the oil drum can easily roll out of control, endangering personal safety.

[0005] 2. Difficulty in refueling in low-temperature environments: In cold seasons or high-latitude regions, the viscosity of lubricating oil increases sharply as the temperature decreases, and its fluidity deteriorates, making it difficult for the oil to flow out of the oil drum naturally. External heating (such as steam purging or wrapping with an electric blanket) must be used to complete the refueling, which seriously affects maintenance efficiency and project progress. Utility Model Content

[0006] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a refueling truck structural assembly that is simple in structure, has good stability, and improves the convenience and efficiency of refueling.

[0007] The objective of this utility model can be achieved by addressing the following technical problem: proposing a refueling truck structural assembly, including: a forklift body;

[0008] A drive assembly and a clamping assembly are provided. The drive assembly is mounted on the forklift body and includes a lifting component and a rotating component. The lifting component drives the clamping assembly to reciprocate in a vertical direction, and the rotating component drives the clamping assembly to rotate relative to the forklift body. The clamping assembly is connected to the movable end of the drive assembly and includes a plurality of oil drum clamps arranged opposite to each other. The oil drum clamps are used to clamp and restrict the relative displacement of the plurality of oil drums.

[0009] A locking assembly is provided on the clamping assembly. The locking assembly extends above the oil drum clamp and is movably pressed against the oil drum to restrict the oil drum from moving relative to the oil drum clamp along its axial direction.

[0010] An oil filter assembly is installed on the forklift body. The oil filter assembly is connected to the oil tank via an oil pipe to achieve circulation filtration and heating of the oil in the oil tank.

[0011] In the above-mentioned refueling truck structural assembly, the lifting component includes:

[0012] A movable frame, the rotating component is connected to the movable frame, the movable frame is connected to a roller, the forklift body is provided with a fixed frame, the fixed frame is formed with a guide groove, and the roller is movably disposed in the guide groove;

[0013] A lifting cylinder is mounted on the forklift body, and the output end of the lifting cylinder is provided with a connecting shaft, which is connected to the movable frame;

[0014] A traction chain, one end of which is mounted on the fixed frame and the other end of which is connected to the movable frame.

[0015] In the above-mentioned refueling truck assembly, a vision camera is provided at the top of the fixed frame, and a human-machine interface panel is provided on the forklift body. The vision camera is used to transmit the status of the oil drum to the human-machine interface panel.

[0016] In the above-mentioned refueling truck structural assembly, the rotating component includes an electric rotating disk and a flange. The electric rotating disk is connected to the movable frame, and the flange is disposed on the electric rotating disk and connected to the clamping assembly.

[0017] In the above-mentioned refueling vehicle structural assembly, the clamping component further includes:

[0018] A support frame is mounted on the flange.

[0019] The driving component and the clamping plate are symmetrically arranged on the support frame. The output end of each driving component is connected to the clamping plate, and at least two oil drum clamps are installed on each clamping plate, so that when the driving component drives the clamping plates to move closer to each other, the oil drum clamps can grab the oil drum.

[0020] In the above-mentioned refueling truck structural assembly, a traction wheel is movably mounted on the fixed frame, and a locking groove is formed on the traction wheel, into which the oil pipe is movably locked.

[0021] In the above-mentioned refueling truck structural assembly, the oil filtration component includes an oil filter and a heater. The oil filter element in the oil filter is made of nickel-titanium Monel alloy and has trapezoidal filter holes. The heater is used to circulate and heat the oil in the oil tank.

[0022] In the above-mentioned refueling truck structural assembly, the drive component further includes a telescopic arm and a shear force sensor. The telescopic arm is symmetrically arranged on both sides of the bottom of the fixed frame to support the oil drum pad. The shear force sensor is used to measure the change in the amount of oil in the oil drum during the refueling process.

[0023] In the above-mentioned refueling truck structural assembly, the locking component includes an extension plate and a locking member. The extension plate is detachably connected to the clamping plate, and the locking member is movably disposed on the extension plate and can move vertically to press against the oil drum.

[0024] In the above-mentioned refueling truck structural assembly, the oil drum clamp is composed of several planes connected together, and the two adjacent planes are arranged at an angle.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] (1) The present invention provides a refueling truck structure assembly that integrates forklift functions with oil drum handling, positioning, clamping, locking, oil filtration and heating into a single design. The lifting and rotating motion of the clamping component is achieved by the drive component, which improves the spatial adaptability and operational flexibility of the oil drum during loading, unloading, transportation and operation. The clamping component can stably clamp multiple oil drums to prevent them from colliding or slipping. The locking component further restricts the axial movement of the oil drums and improves transportation safety. The oil filtration component can circulate and heat the oil in the oil drums on site to prevent impurities from clogging the refueling system. It is suitable for cold environments or maintenance scenarios for long-term oil storage, and significantly improves the efficiency and safety of refueling operations.

[0027] (2) The refueling rate can be adjusted on-site through the human-machine interaction panel and the display, and the oil quality can be observed and corresponding parameters can be set in real time. At the same time, it effectively avoids blind spots caused by the obstruction of the fixed frame for the operator, and improves the safety performance of the refueling truck structure.

[0028] (3) The oil drum clamp adopts a multi-plane bending structure, with specific angles between each plane, so that its outline is more in line with the curved shape of the standard oil drum, increasing the contact area and improving the clamping friction and stability; at the same time, the structure has good rigidity and anti-deformation ability, and is not easy to damage the surface of the oil drum under the action of clamping force, thus improving the reliability of clamping.

[0033] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0034] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0035] like Figures 1 to 3 As shown, the present invention provides a refueling truck structural assembly, including a forklift body 1, a drive assembly 2, a clamping assembly 3, a locking assembly, and an oil filter assembly 4.

[0036] The drive assembly 2 is mounted on the forklift body 1 and includes a lifting component 20 and a rotating component 21. The lifting component 20 drives the clamping assembly 3 to reciprocate in the vertical direction, and the rotating component 21 drives the clamping assembly 3 to rotate relative to the forklift body 1. The clamping assembly 3 is connected to the movable end of the drive assembly 2 and includes several oil drum clamps 30 arranged opposite each other. The oil drum clamps 30 are used to clamp and restrict the relative displacement of several oil drums. The locking component is mounted on the clamping assembly 3 and extends above the oil drum clamps 30, and is movably pressed against the oil drums to restrict the oil drums from moving relative to the oil drum clamps 30 along their axial direction. The oil filter assembly 4 is mounted on the forklift body 1 and is connected to the oil drums through an oil pipe to achieve circulating filtration and heating of the oil in the oil drums.

[0037] This embodiment primarily addresses the problems of inconsistent fuel quality and low refueling efficiency caused by the current practice of relying entirely on manual intervention in refueling. Specifically, for example... Figures 1 to 3As shown, the operator drives the forklift body 1 to the oil drum storage area, aligns it with the multiple standard oil drums to be transported, and activates the clamping assembly 3 through the control system on the forklift body 1 (not shown in the figure), thereby driving the oil drum clamps 30 arranged opposite each other to synchronously close and clamp the required oil drums; then, the locking assembly moves down from above and presses against the top edge of the oil drum (drum lid area) to form an axial limit constraint, ensuring that the oil drum will not move axially or fall off due to gravity or inertia during subsequent lifting and tilting; after clamping and locking are completed, the lifting component 20 drives the clamping assembly 3 and the clamped oil drum to rise smoothly in the vertical direction to the set height (usually a safe height to avoid ground obstacles and ensure smooth rotation of the oil drum); as the rotating component 21 drives the entire clamping assembly 3 and the oil drum to slowly tilt, the oil drum can smoothly transition from an upright state to an inclined or inverted state, and the oil can flow out naturally by gravity. It is worth noting that in low-temperature environments, because the oil drum is connected to the oil filter assembly 4, the tilted oil drum allows the oil to complete the filtering and / or heating functions. After circulating through the oil filter assembly 4, the oil meets the cleanliness and temperature requirements. Therefore, this structure integrates forklift functionality with oil drum handling, positioning, clamping, locking, filtering, and heating, forming a multi-functional refueling truck assembly. This not only improves the spatial adaptability and operational flexibility of the oil drums during loading, unloading, transportation, and operation, but also effectively prevents oil drums from colliding or slipping. The locking assembly further restricts axial movement of the oil drums, enhancing transportation safety. Simultaneously, the oil filter assembly 4 allows for on-site circulating filtration and heating of the oil in the drums, preventing impurities from clogging the refueling system and improving fuel quality and fluidity. This is particularly suitable for cold environments or long-term oil storage maintenance scenarios, significantly improving refueling efficiency and safety.

[0038] The lifting component 20 includes: a movable frame 200, a rotating component 21 connected to the movable frame 200, a roller 201 connected to the movable frame 200, a fixed frame 10 provided on the forklift body 1, a guide groove 100 formed on the fixed frame 10, and the roller 201 movably disposed in the guide groove 100; a lifting cylinder 202 provided on the forklift body 1, the output end of the lifting cylinder 202 provided with a connecting shaft, the connecting shaft being connected to the movable frame 200; and a traction chain 203, one end of which is provided on the fixed frame 10, and the other end of which is connected to the movable frame 200.

[0039] When the refueling truck is in standby or driving mode, the movable frame 200 is located at the lower limit position of the fixed frame 10. At this time, the lifting cylinder 202 is in the retracted state, the traction chain 203 is pre-tensioned but unloaded, and the movable frame 200 is embedded in the vertical guide groove 100 on the fixed frame 10 through the rollers 201 connected on both sides, forming a sliding fit to limit the lateral displacement of the movable frame 200 during the lifting process. During the lifting operation, the control system drives the piston rod of the lifting cylinder 202 to extend, and its output end is connected to the movable frame 200 through the connecting shaft, thereby pushing the movable frame 200. The 00 moves back and forth in the vertical direction synchronously. During this process, the roller 201 rolls in the guide groove 100 to achieve low-friction and high-stability linear motion. At the same time, one end of the traction chain 203 is fixed to the top of the fixed frame 10, and the other end is connected to the middle or lower part of the moving frame 200. Since the length of the traction chain 203 is fixed, during the upward movement of the moving frame 200, the traction chain 203 gradually changes from a slack state to a tension state, playing a dual role of auxiliary guidance and anti-fall. It not only prevents the moving frame 200 from suddenly falling due to cylinder failure, but also balances the off-center load torque during the lifting process.

[0040] The rotating component 21 includes an electric rotating disk 210 and a flange 211. The electric rotating disk 210 is connected to the movable frame 200, and the flange 211 is disposed on the electric rotating disk 210 and connected to the clamping assembly 3.

[0041] like Figure 2 As shown, after the refueling truck arrives near the target equipment and completes positioning, the control system issues a flipping command. The electric rotary disk 210 (such as a slewing bearing device driven by a servo motor) starts working. The motor drives the internal gear ring or external gear to rotate through the reduction mechanism, which in turn drives the integrated flange 211 to rotate synchronously. The rotational motion of the flange 211 is directly transmitted to the clamping assembly 3, causing the entire clamping frame to slowly tilt around its rotation center axis. Preferably, the flipping angle in this embodiment is 0°~90°~180°, ensuring that the bottom of the oil drum is raised and the top is tilted down. Gravity is used to allow the oil to flow out naturally from the lower oil outlet of the oil drum, thereby completing a series of operations such as filtration, heating, and refueling. Therefore, this rotating structure achieves high-precision, high-torque rotary motion output, allowing the clamping assembly 3 to rotate flexibly within a horizontal plane of 30°. This facilitates adjusting the orientation of the oil drum to connect with refueling interfaces or stacking areas in different directions. The overall structure is stable and reliable, with fast start-stop response and high positioning accuracy, enhancing the spatial adaptability and automation potential of the entire machine.

[0042] The clamping assembly 3 also includes: a support frame 31, which is mounted on the flange 211; a drive member 32 and a clamping plate 33, which are symmetrically mounted on the support frame 31. The output end of each drive member 32 is connected to a clamping plate 33, and at least two oil drum clamps 30 are installed on each clamping plate 33, so that when the drive member 32 drives the clamping plates 33 to move closer to each other, the oil drum clamps 30 can grab the oil drum.

[0043] like Figure 2 As shown, in this embodiment, the clamping plates 33 are all movably hinged to both ends of the support frame 31. When the control system activates the drive component 32, the clamping plates 33 rotate relative to the support frame 31 through the synchronous extension or retraction of the piston rod. This allows the oil drum clamps 30 to clamp the oil drum. Preferably, the drive component 32 in this embodiment can be hydraulically driven, pneumatically driven, or electrically driven. The cooperation between the clamping plates 33 and the drive component 32 achieves bidirectional clamping action, resulting in uniform clamping force distribution, adaptability to oil drums of different sizes, and good clamping stability. Furthermore, multiple oil drum clamps 30 are provided on each side of the clamping plate 33, allowing for the simultaneous and secure clamping of multiple oil drums, increasing the capacity for a single operation.

[0044] like Figure 2 As shown, the presence of the fixed frame 10, lifting cylinder 202, and traction chain 203 can obstruct the worker's view during operation. Therefore, in this embodiment, a vision camera (such as an industrial high-definition camera or an intelligent vision module with supplementary lighting, not shown in the figure) is installed at the top of the fixed frame 10. A camera located on the forklift body 1 is also provided. Figure 1 The human-machine interface panel (such as a touch screen operating terminal, not shown in the figure) on the control console 11 is connected to the control console 11 via an internal communication bus (such as a CAN bus or Ethernet), forming an intelligent human-machine collaborative system that integrates status monitoring, information display, and operation control. This enables real-time monitoring and visual display of the oil drum's status (such as placement, tilting status, and liquid level), facilitating operators to accurately judge the working environment remotely or at close range and reducing the risk of human error. Especially in complex working conditions, it can assist in automatic alignment and safety warnings, improving the level of operational intelligence and work safety, and reducing the accident rate.

[0045] The fixed frame 10 is also equipped with a traction wheel, and a locking groove is formed on the traction wheel, into which the oil pipe is movably locked.

[0046] In this embodiment, since the oil in the oil drum needs to be filtered and heated, an oil pipe is connected between the two. The oil pipe passes through the fixing frame 10 and connects to the oil filter assembly 4. Because the oil drum needs to be tilted, the overall structure of the oil pipe is relatively long, providing sufficient space for the oil drum to tilt. The design of the traction wheel (located near the top of the fixing frame 10, not shown in the figure) and its locking groove in this embodiment can guide and store the oil pipe connecting the oil filter assembly 4 and the oil drum in an orderly manner, preventing the oil pipe from getting tangled, squeezed or worn during lifting or rotation, ensuring smooth oil flow; at the same time, it reduces the amount of manual work for cleaning the oil pipe, extends the service life of the oil pipe, and improves the reliability of system operation and the cleanliness of the site.

[0047] The oil filtration assembly 4 includes an oil filter and a heater. The oil filter element in the oil filter is made of nickel-titanium Monel alloy and has trapezoidal filter holes. The heater is used to circulate and heat the oil in the oil tank.

[0048] In this embodiment, the oil filter element is made of titanium-nickel Monel alloy using a trapezoidal pore design and a leading international sintering process. This type of filter element features a filtration accuracy of up to ≤1μm, stable filtration accuracy unaffected by oil temperature and pressure, consistent high accuracy in oil sample testing, corrosion resistance (can be cleaned with 5%-10% sulfuric acid and alkaline solutions), and a long service life (it can be used for its entire lifespan without replacement). By working in conjunction with the heater, the oil temperature can be raised by ≥30℃ in low-temperature environments (such as winter or cold regions), significantly reducing oil viscosity. The circulating heating method avoids localized overheating, preventing lubricant oxidation or additive decomposition. Heating enhances oil fluidity, increasing flow rate by over 40%, shortening refueling time. Therefore, the overall structure of this filter assembly effectively intercepts fine particulate impurities while being less prone to clogging, exhibiting strong flow capacity and high filtration efficiency. The heater achieves circulating oil heating, rapidly improving the fluidity of low-temperature oils and ensuring smooth refueling, making it particularly suitable for winter or high-viscosity oil applications, comprehensively improving refueling quality and efficiency. It should be noted that the structure and working principle of the filter and heater in this embodiment are the same as those of the prior art, and will not be described in detail here.

[0049] The drive assembly 2 also includes a telescopic arm 22 and a shear force sensor. The telescopic arm 22 is symmetrically arranged on both sides of the bottom of the fixed frame 10 to support the oil drum pad 220. The shear force sensor is used to measure the change in the amount of oil in the oil drum during the refueling process.

[0050] Once the forklift reaches the oil drum storage area and completes its positioning, the clamping plate 33 drives the oil drum clamp 30 to clamp the oil drums. Simultaneously, the control system activates the telescopic arm 22 (which can be a hydraulic cylinder, electric push rod, or pneumatic cylinder) to extend it horizontally until it provides stable support for the oil drum pad 220. This ensures that multiple oil drums are stably fixed under the combined action of the oil drum pad 220 and the locking components, preventing swaying or displacement during flipping. Furthermore, the forklift can adapt to oil drum pallets or pads of different sizes when the two telescopic arms 22 move closer or further apart, enhancing the equipment's versatility. The shear force sensor integrated into the clamping plate 33 can monitor changes in oil drum weight in real time, accurately calculate the amount of oil added or consumed, and achieve digital metering management. This avoids the risks of overfilling or underfilling, contributing to fuel consumption statistics, cost control, and the construction of an automated refueling control system, thus improving the level of intelligent management.

[0051] The locking assembly includes an extension plate and a locking element. The extension plate is detachably connected to the clamping plate 33, and the locking element is movably mounted on the extension plate and can move vertically to press against the oil drum.

[0052] In this embodiment, the extension plate (not shown in the figure) extends above the clamping plate 33, allowing the locking component (not shown in the figure) to be detachably connected to the top of the extension plate while simultaneously enabling the locking component to stably lock the oil drum during downward movement. Therefore, this embodiment achieves one-time automatic clamping and axial locking of multiple oil drums (e.g., four drums) through the dual fixing mechanism of the oil drum clamp 30 and the locking component, completely replacing manual handling and manual support. The locking component effectively prevents the oil drums from axially slipping during lifting, transportation, and tilting, avoiding the risk of falling from heights. The fully mechanized operation reduces the opportunity for personnel to come into close contact with heavy oil drums, significantly reducing the probability of workplace accidents. Preferably, the locking component in this embodiment can be replaced by other fastening components such as double-ended bolts or locking pins.

[0053] Preferably, the oil drum clamp 30 in this embodiment adopts a multi-plane 300-degree bending structure, with each plane 300 forming a specific angle, making its outline more closely fit the curved shape of the standard oil drum, increasing the contact area, and improving clamping friction and stability; at the same time, this structure has good rigidity and anti-deformation ability, and is not easily damaged on the surface of the oil drum under clamping force; the angle design can also be adjusted according to different oil drum shapes to achieve customized matching, taking into account both protection and clamping reliability.
