Description

Technical Field

[0001] This utility model relates to the field of hydraulic machinery, specifically an integrated hydraulic lifting platform. Background Technology

[0002] A hydraulic lifting platform is a multi-functional lifting and loading / unloading machine. It can achieve vertical lifting and is widely used in factories, warehouses, parking lots, and other places for handling goods and facilitating high-altitude operations. The hydraulic system is its core component, which enables the platform to lift and lower smoothly through the operation of components such as oil pumps and hydraulic cylinders.

[0003] Existing hydraulic lifting platforms have several problems and limitations. Regarding structural stability, due to the numerous equipment and congested space at aircraft production sites, mobile hydraulic lifting platforms are prone to collisions with other equipment or debris during operation. Some platforms, due to a lack of protection or material defects, are susceptible to swaying, deformation, or even structural damage when carrying heavy loads or encountering significant external forces. In terms of the hydraulic system, most use oil pipes for oil inlet, which often leads to problems such as hydraulic oil leakage and hydraulic cylinder wear. This results in unstable platform lifting speeds and may increase energy consumption and maintenance costs. Utility Model Content

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] This utility model provides an integrated hydraulic lifting platform consisting of a protective section, a loading platform, a scissor lift assembly, a drive unit, and casters. The protective section comprises a double-layer composite structure of an inner plate and an outer shell, enhancing its resistance to deformation and overall rigidity. A buffer cavity can be reserved between the inner plate and the outer shell to fill with shock-absorbing material, further absorbing impact loads. The protective section adopts a box-type structure, which has high bending and torsional resistance, effectively distributing loads, avoiding localized stress concentration, and enhancing impact resistance, making the platform less prone to damage. The scissor lift assembly is a key component for achieving the lifting function of the integrated hydraulic lifting platform. It consists of multiple sets of cross arms and connecting parts arranged in a crisscross pattern. When the drive unit is activated, the hydraulic cylinder pushes the cross arms to extend and retract, enabling the platform to lift smoothly. The structural dimensions of the scissor arms can be precisely designed according to the platform's lifting height, load-bearing capacity, and overall stability requirements, achieving precise lifting and meeting the needs of different heights. The scissor lift assembly improves the platform's stability, reduces the failure rate, and enhances the platform's safety and reliability.

[0025] This invention utilizes an integrated hydraulic press as the driving device, including an oil pump, hydraulic cylinder, and motor. Each end of the hydraulic cylinder has an oil nozzle, allowing oil to be supplied from either the lower or upper nozzle. This integrated design eliminates the need for hoses, solving the problem of oil leakage between the pump and cylinder compared to previous hydraulic cylinders, thus reducing the risk of hydraulic oil leakage. The integrated hydraulic press draws and pressurizes hydraulic oil from the tank via the oil pump, delivering it to the hydraulic cylinder. This hydraulic cylinder's piston moves, driving the scissor lift assembly, thereby achieving the platform's lifting and lowering movement. Both lifting and lowering are driven by the oil pump, solving the problem of uncontrollable speed during descent in traditional hydraulic lifting vehicles. Casters are installed at the bottom of the lower protective section, allowing for flexible platform movement.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0037] Reference Figure 1-7 This utility model proposes an integrated hydraulic lifting platform, comprising:

[0038] Upper protective section 10;

[0039] A storage platform 20 is disposed above the upper protective part 10;

[0040] Lower protective part 80, which is disposed below the upper protective part 10;

[0041] A base plate 60 is disposed below the lower protective part 80;

[0042] Two sets of scissor lift assemblies 30, each scissor lift assembly 30 including at least one set of "X"-shaped cross arms, a connecting rod 31 between the two sets of scissor lift assemblies 30, one side of each scissor lift assembly 30 being slidably connected to the storage platform 20 and the base plate 60 in the left and right directions, and the other side being hinged to the storage platform 20 and the base plate 60 respectively;

[0043] An integrated hydraulic press 40 is inclinedly disposed between two sets of scissor lift assemblies 30. The integrated hydraulic press 40 includes a motor 42, an oil pump 43, and a hydraulic cylinder 44. One end of the hydraulic cylinder 44 is movably connected to the lower protective part 80, and the other end of the hydraulic cylinder 44 is connected to the connecting rod 31 through a hinge 41. Each end of the hydraulic cylinder 44 has an oil nozzle. The motor 42 and the oil pump 43 are integrally connected and are disposed on one side of the hydraulic cylinder 44 through a fixed bracket 45. The oil pump 43 is connected to the two oil nozzles.

[0044] Casters 50 are located at the bottom of the base plate 60.

[0045] This utility model provides an integrated hydraulic lifting platform consisting of a protective section, a loading platform 20, a scissor lift assembly 30, a drive unit, and casters 50. The protective section serves as the supporting foundation of the entire platform, using high-strength steel as the main material to withstand significant loads and impacts, ensuring the platform's stability and safety during long-term use. The scissor lift assembly 30 is a key component for achieving the lifting function of the integrated hydraulic lifting platform. It consists of multiple sets of cross arms arranged in a crisscross pattern and connecting parts. When the drive unit is activated, the hydraulic cylinder 44 pushes the cross arms to extend and retract, enabling the platform to lift smoothly. The structural dimensions of the scissor lift assembly 30 can be precisely designed according to the platform's lifting height, load-bearing capacity, and overall stability requirements, achieving precise lifting and meeting the needs of different heights. The scissor lift assembly 30 improves the platform's stability, reduces the failure rate, and enhances the platform's safety and reliability. This utility model uses an integrated hydraulic press 40 as the driving device, which integrates an oil pump 43, a hydraulic cylinder 44, a motor 42, etc. The hydraulic cylinder 44 has an oil nozzle at each end, and the hydraulic cylinder 44 can pump oil from either the lower or upper oil nozzle. This integrated design eliminates the need for hoses, and compared with the previous hydraulic cylinder 44, it solves the problem of oil leakage from the hose between the oil pump 43 and the hydraulic cylinder 44, reducing the risk of hydraulic oil leakage.

[0046] One embodiment also includes a battery, which is connected to the motor 42 via a wire after being programmed. When power is available, the motor is used as the driving source; when power is unavailable, the battery is used. The battery allows the platform to be used in power-free scenarios, meaning it can be used even in the event of a sudden power outage using a backup battery. The integrated hydraulic press 40 draws hydraulic oil from the oil tank and pressurizes it via the oil pump 43, then delivers the hydraulic oil to the hydraulic cylinder 44, pushing the piston of the hydraulic cylinder 44 to move. The piston drives the scissor lift assembly 30, thereby achieving the lifting and lowering movement of the platform. Both lifting and lowering are driven by the oil pump 43, solving the problem of uncontrollable speed during descent in traditional hydraulic lifting vehicles. Casters 50 are installed at the bottom of the lower protective section 80, allowing the platform to move flexibly.

[0047] Furthermore, a reinforcing plate 23 and a first mounting component 24 are provided below the storage platform 20, and the bottom of the reinforcing plate 23 is symmetrically provided with a first horizontally extending slide rail 231.

[0048] The base plate 60 includes two first base plates 61 and a second base plate 62. Each of the two first base plates 61 is provided with a second slide rail 611 extending laterally, and a second mounting member 622 is provided above the second base plate 62.

[0049] The upper and lower ends of one side of the two sets of scissor lift assemblies 30 are slidably connected to the first slide rail 231 and the second slide rail 611 via sliders 32, and the upper and lower ends of the other side are hinged to the first mounting member 24 and the second mounting member 622, respectively.

[0050] The loading platform 20 is connected to the scissor lift assembly 30 via high-strength bolts. A reinforcing plate 23 is provided at the connection point to distribute stress and prevent loosening during prolonged use or under heavy loads. The slider 32 works in conjunction with the slide rail in the integrated hydraulic lifting platform, providing guidance and support. The slide rail is fixed to the reinforcing plate 23 and the first base plate 61, while the slider 32 is mounted on the scissor lift assembly 30. When the platform is raised or lowered, the slider 32 slides on the slide rail, ensuring a smooth movement trajectory for the scissor lift assembly 30 and reducing swaying and vibration. Ball bearings or rollers can be installed inside the slider 32 to reduce friction and improve movement efficiency. Lubricating grease is applied to the contact surfaces of the slide rail and the slider 32 to further reduce friction and extend service life.

[0051] Furthermore, the storage platform 20 includes a storage frame 21 and an anti-slip storage board 22 placed inside the storage frame 21, and the reinforcing plate 23 is located below the anti-slip storage board 22;

[0052] The upper protective part 10 includes an upper inner layer plate 11 and an upper outer shell 12.

[0053] The storage platform 20 is located above the upper protective part 10, and its surface is covered with anti-slip storage board 22 to increase the coefficient of friction and prevent the goods from sliding during the lifting and lowering of the platform.

[0054] Furthermore, the lower protective part 80 includes a lower inner plate 81 and a lower outer shell 82, and the bottom plate 60 is disposed at the bottom of the lower inner plate 81.

[0055] The protective section consists of a double-layer composite structure of an inner plate and an outer shell, enhancing its resistance to deformation and overall rigidity. A buffer cavity can be reserved between the inner plate and the outer shell to be filled with shock-absorbing material, further absorbing impact loads. The protective section adopts a box-shaped structure, which has high bending and torsional resistance, effectively distributing loads, avoiding localized stress concentration, enhancing impact resistance, and making the platform less prone to damage.

[0056] Furthermore, the caster 50 includes two fixed wheels 51 and two swivel wheels 52.

[0057] The casters 50 of the integrated hydraulic lifting platform come in various types, including swivel wheels 52 and fixed wheels 51. The swivel wheels 52 can rotate freely, facilitating platform turning; the fixed wheels 51 can only move in a fixed direction, providing stable support. The platform is typically equipped with four casters 50, with the first two being swivel wheels 52 and the last two being fixed wheels 51. The swivel wheels 52 in front facilitate flexible platform turning; the fixed wheels 51 in the rear provide stable support, preventing the platform from tipping over during movement. In this embodiment, the fixed wheels 51 are located below the first base plate 61, and the swivel wheels 52 are located below the second base plate 62. The four casters 50 are evenly distributed at the four corners of the platform, ensuring stability during movement. The casters 50 are made of materials such as nylon and polyurethane, offering good wear resistance and adaptability to different ground conditions. In another embodiment, the casters 50 are also equipped with brake devices to fix the platform position at any time, ensuring operational safety. The platform is equipped with directional wheels 51 and omnidirectional wheels 52, which enable it to move flexibly and operate stably, meeting the needs of different scenarios.

[0058] Furthermore, a limiting member 53 is provided on the base plate 60, and the limiting member 53 is located at one end of the second slide rail 611 near the second mounting member 622.

[0059] By setting the limiting component 53, the bending resistance of the platform is increased, ensuring that it will not deform when bearing heavy objects, and the slider 32 is prevented from sliding out of the second slide rail 611.

[0060] Furthermore, a power plug 70 is provided below the lower protective part 80, and a control button 13 is provided on the outside of the upper protective part 10.

[0061] In this embodiment, the power supply plug 70 is compatible with both mains power and backup power, ensuring the platform can be safely reset in the event of a power outage. The control buttons 13 include three buttons: an up button, a down button, and an emergency stop button. The up button controls the platform's ascent, the down button controls its descent, and the stop button quickly stops the platform's movement in an emergency. The emergency stop function is typically set to a red button, clearly distinguishable from other function buttons. In case of an emergency, the operator can quickly press the emergency stop button to immediately stop the platform. Currently, most lifting platforms require a control box for start / stop and operation settings. During operation, lifting and lowering operations can only be performed by personnel on the ground at the control box, requiring at least two people working together. However, in this integrated hydraulic lifting platform, since the upper protective unit 10 rises and falls with the operator during operation, by placing the control buttons 13 on the upper protective unit 10, the operator can complete the work independently on the integrated hydraulic lifting platform, saving labor costs and improving work efficiency.

[0062] Furthermore, it also includes support legs 90, which are disposed on both sides of the lower protective part 80. The support legs 90 can be existing lifting support legs, which will not be described in detail here. When the lifting platform moves to the required position, the telescopic ends of the support legs 90 are lowered to abut against the ground to support the platform and further ensure the stability of the lifting platform. When it is necessary to move or when it is not necessary to support, the telescopic ends of the support legs 90 can be retracted away from the ground.

[0063] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
