Description

Technical Field

[0001] This invention relates to the field of lifting platform technology, and in particular to a lifting platform device with hoisting function and its usage method. Background Technology

[0002] In the construction and maintenance of large-span spatial structures, lifting platforms, as core aerial work equipment, are widely used in steel structure installation, formwork erection, and structural inspection due to their height adjustability. The industry's demands for their operational efficiency and functional adaptability are constantly increasing with the upgrading of construction techniques. Existing lifting platforms consist of a support platform, a lifting mechanism, and a mobile base, and can only achieve high-altitude lifting and relocation of personnel and simple tools. They lack dedicated material handling structures, and the transfer of construction materials must rely on external equipment.

[0003] Existing lifting platforms have obvious functional defects. First, they only have a single high-altitude lifting function and lack an integrated material handling structure. They cannot independently complete the vertical and horizontal transportation of materials and still need to rely on external equipment to transfer materials to the perimeter of the platform, which greatly reduces transportation efficiency. Second, a few lifting platforms equipped with simple lifting tools do not have a professional multi-dimensional adjustment structure for the lifting tools, which can only achieve simple vertical lifting and have a very small operating coverage area. Summary of the Invention

[0004] To overcome the above shortcomings, the present invention provides a lifting platform device and a method of use with hoisting function, which aims to improve the problem that the existing lifting platforms only have a single high-altitude lifting function and cannot independently complete the hoisting of materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lifting platform device with hoisting function, comprising a lifting platform assembly, a scissor lift assembly, and a chassis assembly; the scissor lift assembly is fixedly mounted on the upper surface of the lifting platform assembly, and the chassis assembly is fixedly mounted on the lower surface of the lifting platform assembly; the lifting platform assembly includes a lifting platform, a scissor lift mechanism, and a control console; the scissor lift mechanism is movably mounted on the lower surface of the lifting platform and is electrically connected to the control console; the scissor lift assembly includes a slide rail, an electric slider, a rotary box, and a support. The system includes a support column, a telescopic boom, a hydraulic cylinder, an electric reel, a steel cable, and a hook. The slide rail is fixedly installed on the upper surface of the lifting platform. The electric slider is movably installed on the outer surface of the slide rail. The rotary box is movably installed on the upper surface of the electric slider. The support column is fixedly installed on the upper surface of the rotary box. The telescopic boom is hinged to the upper end of the support column. The two ends of the hydraulic cylinder are respectively hinged to the support column and the telescopic boom. The electric reel is fixedly installed inside the support column. The steel cable is wrapped around the outer surface of the electric reel.

[0007] Preferably, a movable door is hinged to the rear outer surface of the guardrail, and a movable pin is provided on the inner outer surface of the movable door. The end of the scissor lift mechanism away from the lifting platform is fixedly installed on the upper surface of the base of the chassis assembly.

[0008] Preferably, a battery compartment and a storage compartment are fixedly installed on the upper surface of the base of the chassis assembly; a protective plate is fixedly installed on the upper surface of the battery compartment and the storage compartment, and a ladder is fixedly installed on the rear side of the storage compartment and the protective plate.

[0009] Preferably, the telescopic boom assembly further includes a sliding wheel, which is movably mounted on the front side of the telescopic boom, and the end of the steel cable away from the electric reel is wound around the sliding wheel and then fixedly connected to the hook.

[0010] Preferably, the chassis assembly includes a base, a plurality of electric wheels are fixedly mounted on the lower surface of the base, four extension arms are mounted on the upper surface of the base, and electric support legs are fixedly mounted on the end of each extension arm away from the electric wheels. The electric wheels and electric support legs are all electrically connected to the control console.

[0011] A method of using a lifting platform device with hoisting function includes the following steps:

[0012] S1. Equipment movement and positioning: The electric wheels are controlled by the control console to move the entire lifting platform to the designated construction work position of the large-span spatial structure.

[0013] S2. Platform Stability Support: Adjust the placement direction of the extension arm via the control console, then control the electric outriggers to extend downwards and touch the ground, lifting the electric wheels off the ground to achieve stable platform support.

[0014] S3, Lifting of working platform: Construction personnel enter the lifting platform through the ladder and movable door and lock the movable pin. They control the scissor lifting mechanism through the control console to lift the platform to the designated working height.

[0015] S4.

[0017] Preferably, in step S2, if the electric outriggers are not fully in contact with the ground and the electric wheels are not lifted off the ground, the control console will lock the lifting action of the boom assembly and the lifting action of the scissor lift mechanism; in step S3, if the movable pin is not fully locked, the control console will lock the lifting action of the scissor lift mechanism until the movable pin is locked in place.

[0018] The present invention has the following beneficial effects:

[0019] 1. This invention integrates lifting operations and material handling, giving the equipment the dual core functions of high-altitude lifting and material transfer, significantly improving construction efficiency and expanding the functional attributes of the lifting platform. The lifting platform assembly relies on a scissor lift mechanism to smoothly raise and lower the platform, accurately transporting construction personnel and equipment to designated heights in large-span spatial structures. The lifting platform, as a dedicated support platform, provides a stable working plane for construction personnel, meeting the needs of construction operations at different heights. Simultaneously, a straight boom crane assembly is integrated into the lifting platform assembly, enabling direct vertical and horizontal material transport. It can accurately lift materials from the ground, other construction platforms, or distant locations to the high-altitude work point on the lifting platform. During construction, there is no need to repeatedly control the lifting platform to transfer materials, completely changing the traditional single function of lifting platforms. This allows construction personnel to directly receive materials at the work point, effectively reducing material transfer steps and improving overall construction efficiency.

[0020] 2. The straight boom crane assembly of this invention can achieve flexible adjustment in multiple dimensions, accurately adapting to the complex hoisting needs of large-span spatial structures, and significantly expanding the coverage and accuracy of hoisting operations. The slide rail provides stable guidance and support for the electric slider. The electric slider moves along the slide rail, driving the slewing box and the upper hoisting components to complete the smooth adjustment of the lateral position, realizing flexible lateral switching of hoisting points; the slewing box moves with the electric slider and can perform horizontal rotation, driving the support column and subsequent hoisting components to adjust their direction, realizing flexible adjustment of the hoisting direction; the support column provides load-bearing support for the telescopic boom, which is hinged to the upper end of the support column and can perform telescopic movement, adjusting its own length according to construction needs, changing the horizontal extension distance of the straight boom crane assembly, and accurately reaching hoisting points at different distances; the two ends of the hydraulic cylinder are respectively hinged to the support column and the telescopic boom, and the telescopic movement of the hydraulic cylinder can control the pitch angle of the telescopic boom; the sliding wheel is movably installed on the front side of the telescopic boom, changing its position synchronously with the adjustment of the telescopic boom, providing smooth guidance for the steel cable. The components work together to achieve precise adjustment of the hoisting operation in multiple dimensions such as lateral movement, rotation, extension distance, and pitch angle. It can accurately target materials to be hoisted in different positions and adapt to the hoisting needs of multiple points in a large span space.

[0021] 3. This invention uses a control console as the overall control center, combining centralized operation with safety detection and locking functions, providing comprehensive safety assurance for equipment operation from the control level. As the core control component of the equipment, the control console can centrally control the lifting and lowering movements of the lifting platform assembly, the lifting movements of the boom crane assembly, and the movement and support movements of the chassis assembly, making construction operations more convenient. Simultaneously, the control console integrates safety detection functions, which can monitor key safety conditions during equipment operation in real time. When abnormal safety conditions such as unlocked sliding door latches, incomplete electric outrigger support, or overloaded lifting weight are detected, the corresponding moving parts will be automatically locked, stopping the lifting and lowering movements of the scissor lift mechanism or the lifting movements of the boom crane assembly. This avoids safety risks such as falls from heights, equipment overturning, and material falling caused by improper operation or abnormal equipment conditions, ensuring the safety of construction personnel and equipment.

[0022] 4. The chassis assembly of this invention possesses flexible mobility and stable support performance, providing a reliable foundation for the overall operation of the equipment and adapting to the complex working conditions of construction sites with large spans. The base, as the fundamental load-bearing component of the chassis assembly, stably supports the entire weight of the lifting platform assembly and the boom crane assembly, providing a solid load-bearing foundation for the equipment. The electric wheels on the underside of the base can drive the entire equipment to complete flexible movement and steering, allowing for rapid adjustment to the designated construction position without additional transfer equipment, significantly improving the equipment's flexibility in relocation at the construction site and adapting to the construction needs of multiple work points in large spans. The extension arm connecting the battery compartment, storage compartment, and base can flexibly adjust its support position. Its electric outriggers can extend downwards and firmly contact the ground, lifting the electric wheels off the ground, creating a multi-point stable support structure for the equipment. This effectively counteracts the center of gravity shift caused during material lifting, preventing problems such as swaying and overturning, providing a stable working foundation for high-altitude lifting and material handling operations, and ensuring the overall operational safety of the equipment from a structural perspective.

Detailed Implementation

[0031] 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, and 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.

[0032] Example 1, refer to Figures 1-6 A lifting platform device with hoisting function includes a lifting platform assembly 1, a scissor lift assembly 2, and a chassis assembly 3. The scissor lift assembly 2 is fixedly installed on the upper surface of the lifting platform assembly 1, realizing the integration of high-altitude operation and material hoisting functions. The chassis assembly 3 is fixedly installed on the lower surface of the lifting platform assembly 1, providing a stable foundation for the movement and support of the entire device. The lifting platform assembly 1 includes a lifting platform 101, a scissor lift mechanism 106, and a control console 103. The scissor lift mechanism 106 is movably installed on the lower surface of the lifting platform 101, which can smoothly drive the lifting platform 101 to complete height adjustment. The scissor lift mechanism 106 is electrically connected to the control console 103, and the lifting action can be precisely controlled through the control console 103. The straight boom crane assembly 2 includes a slide rail 201, an electric slider 202, a slewing box 203, a support column 204, a telescopic boom 205, a hydraulic cylinder 206, an electric reel 208, a steel cable 209, and a hook 210. The slide rail 201 is fixedly installed on the upper surface of the lifting platform 101, providing guidance and support for the lateral movement of the lifting components. The electric slider 202 is movably installed on the outer surface of the slide rail 201, allowing it to smoothly slide along the slide rail 201 to adjust the lifting position. The slewing box 203 is movably installed on the upper surface of the electric slider 202, enabling the upper structure to complete horizontal turning. The support column 204 is fixedly installed on the slewing box 205. The upper surface of 03 provides stable load-bearing support for the hoisting boom. The telescopic boom 205 is hinged to the upper end of the support column 204 and can change the working coverage area by telescoping. The two ends of the hydraulic cylinder 206 are respectively hinged to the support column 204 and the telescopic boom 205 and are used to adjust the pitch angle of the telescopic boom 205. The electric reel 208 is fixedly installed inside the support column 204 and can accurately wind and unwind the steel cable 209. The steel cable 209 is wrapped around the outer surface of the electric reel 208 and is responsible for transmitting the lifting force. The hook 210 is fixedly connected to the end of the steel cable 209 away from the electric reel 208 and is used to directly hang construction materials.

[0033] Example 2, refer to Figures 1-6 Based on Embodiment 1, several guardrails 102 are fixedly installed on the upper surface of the lifting platform 101, and the control console 103 is fixedly installed on the front side of the upper surface of the guardrails 102. The control console 103 is electrically connected to the lifting platform assembly 1, the boom crane assembly 2, and the chassis assembly 3. The guardrails can protect workers working at height, and the control console can centrally control various components, making operation simpler.

[0034] A movable door 104 is hinged to the rear outer surface of the guardrail 102. A movable latch 105 is provided on the inner outer surface of the movable door 104. The end of the scissor lift mechanism 106 away from the lifting platform 101 is fixedly installed on the upper surface of the base 301 of the chassis assembly 3. The movable door facilitates personnel entry and exit, the latch can be locked for protection, and the scissor lift mechanism fixed on the base can improve the stability of the lifting process.

[0035] A battery compartment 107 and a storage compartment 108 are fixedly mounted on the upper surface of the base 301 of the chassis assembly 3; a protective plate 109 is fixedly mounted on the upper surface of the battery compartment 107 and the storage compartment 108, and a ladder 110 is fixedly mounted on the rear side of the storage compartment 108 and the protective plate 109. The battery compartment provides independent power supply, the storage compartment can store construction tools, the protective plate prevents accidental contact by personnel, and the ladder facilitates personnel access to the lifting platform.

[0036] The telescopic boom assembly 2 also includes a pulley 207, which is movably mounted on the front outer surface of the telescopic boom 205. The end of the steel cable 209 away from the electric reel 208 is wound around the pulley 207 and then fixedly connected to the hook 210. The pulley guides the direction of the steel cable, reduces cable wear, and makes the lifting and lowering of the hook smoother.

[0037] The chassis assembly 3 includes a base 301. Several electric wheels 302 are fixedly mounted on the lower surface of the base 301. Extension arms 303 connect the battery compartment 107 and the storage compartment 108 to the base 301. Electric support legs 304 are fixedly mounted on the end of each extension arm 303 away from the base 301. The electric wheels 302 and electric support legs 304 are electrically connected to the control console 103. The electric wheels facilitate equipment movement and relocation, while the electric support legs, in conjunction with the extension arms, provide stable support for the equipment, preventing swaying during operation.

[0038] The slewing box 203 is equipped with a hydraulic motor and gear transmission device. The hydraulic motor, in conjunction with a precision slewing bearing, enables horizontal rotation from 0° to 180°. The hydraulic motor drives the slewing bearing via the gear transmission mechanism, precisely adjusting the horizontal orientation of the support column 204 and the upper lifting components. This ensures accurate slewing positioning and smooth, shock-free operation. The telescopic boom 205 features a multi-stage sleeve structure, driven by built-in multi-stage hydraulic cylinders. The extension and retraction of the hydraulic cylinders directly drive the boom sections to extend or retract synchronously. The extension stroke is controllable, and the boom's rigidity and load-bearing capacity meet the requirements of material lifting operations. The hydraulic cylinder 206 is equipped with an integrated hydraulic control system, which consists of a hydraulic pump, a solenoid directional valve, a relief valve, and a pressure sensor. After the control console 103 outputs control commands, the hydraulic pump outputs high-pressure hydraulic oil, the solenoid directional valve adjusts the direction and flow of the oil circuit, and controls the extension and retraction of the hydraulic cylinder 206 to drive the telescopic boom 205 to complete the pitching action. The system monitors the oil circuit pressure in real time through the pressure sensor. When the hoisting load exceeds the threshold, the relief valve automatically releases pressure to achieve overload protection and ensure that the pitching action is smooth and safe. The extension arm 303 is a telescopic cantilever structure with an internal electric telescopic screw and guide rail. The control console 103 controls a servo motor to drive the screw rotation, enabling radial telescopic adjustment of the arm and flexibly adjusting the support span. The end is fixedly connected to the electric outrigger 304, forming multi-point stable support after deployment, improving the equipment's anti-tipping ability during operation. The electric outrigger 304 is an electric telescopic support structure with a built-in servo motor, telescopic screw, and support foot plate. The control console 103 controls the servo motor to drive the telescopic screw to extend and retract, causing the foot plate to rise and fall, raising the equipment so that the electric wheels 302 are off the ground, ensuring stable support and preventing equipment tipping. The scissor lift mechanism 106 consists of two sets of cross-hinged scissor arms, a lifting hydraulic cylinder, a hinge shaft, and a sliding support. The scissor arms are movably connected via the hinge shaft, with the bottom sliding support cooperating with the base 301 and the upper part hinged to the lifting platform 101. The lifting hydraulic cylinder extends and retracts to drive the scissor arms to open and close, causing the lifting platform 101 to rise and fall vertically. The operation is smooth and the load is evenly distributed, allowing for precise control of the working height.

[0039] Example 3, refer to Figures 1-6 A method for using a lifting platform device with hoisting function includes the following steps:

[0040] S1. Equipment movement and positioning: The electric wheel 302 is controlled by the control console 103 to move the entire lifting platform to the designated construction work position of the large-span spatial structure, and quickly complete the work position adjustment.

[0041] S2. Platform stability support: Adjust the placement direction of the extension arm 303 through the control console 103, and then control the electric outrigger 304 to extend downward and touch the ground, lifting the electric wheel 302 off the ground, eliminating the swaying hazard caused by the moving wheel, and achieving stable support for the platform.

[0042] S3. Lifting of the work platform: Construction personnel enter the lifting platform 101 through the ladder 110 and the movable door 104 and lock the movable pin 105. They control the scissor lift mechanism 106 through the control console 103 to lift the lifting platform 101 to the specified working height to meet the construction needs of different heights.

[0043] S4. Material hoisting operation: The movement of the straight boom crane assembly 2 is controlled by the control console 103. The electric slider 202, slewing box 203, telescopic boom 205 and hydraulic cylinder 206 are adjusted in sequence to move the hook 210 directly above the material to be hoisted. The electric reel 208 is controlled to release the steel cable 209 to lower the hook 210 and hook the material. Then the electric reel 208 is controlled to rewind the steel cable 209 to lift the material. The components of the straight boom crane assembly 2 are adjusted again to hoist the material to the working area of ​​the lifting platform 101, completing the material transfer. Efficient material transportation can be achieved without repeatedly raising and lowering the platform.

[0044] In step S4, the electric slider 202 reciprocates linearly along the slide rail 201, adjusting the lateral position of the boom assembly 2; the rotary box 203 rotates horizontally, adjusting the horizontal direction of the boom assembly 2; the telescopic boom 205 extends and retracts, adjusting the horizontal extension distance of the boom assembly 2; and the hydraulic cylinder 206 extends and retracts, causing the telescopic boom 205 to pitch around the hinge point with the support column 204, adjusting the lifting height. This multi-dimensional adjustment allows for precise alignment of materials and adapts to various lifting points in large-span spaces.

[0045] In step S3, if the movable pin 105 fails to lock, the control panel 103 will lock the lifting action of the scissor lift mechanism 106 until the movable pin 105 is locked in place. In step S2, if the electric outrigger 304 does not fully contact the ground and the electric wheel 302 is not lifted off the ground, the control panel 103 will lock the lifting action of the boom assembly 2 and the lifting action of the scissor lift mechanism 106. The linkage locking design can avoid safety risks and ensure safe and reliable operation.

[0046] The battery pack in battery compartment 107 powers all components. During operation, control console 103 monitors the remaining battery power and the lifting weight of the boom crane assembly 2 in real time. If the lifting weight exceeds a preset threshold or the remaining battery power falls below a preset threshold, control console 103 will issue an alarm and lock the lifting action of boom crane assembly 2. Real-time monitoring and alarm locking prevent overload lifting and power failure, ensuring continuous and stable operation.

[0047] As the core control hub of the entire device, the control console 103 works by establishing real-time electrical connections with various functional components through its built-in control module. It continuously collects various real-time data on equipment operation, performs precise calculations and analyses through its built-in program, and finally outputs corresponding control commands to achieve closed-loop control of the equipment. The control console 103 receives feedback signals from various components in real time, including the remaining battery power data in the battery compartment 107, sensor feedback data on the lifting weight of the straight boom assembly 2, the locking status signal of the movable pin 105, the grounding support signal of the electric outrigger 304, and the operating status data of moving parts such as the electric slider 202, slewing box 203, telescopic boom 205, hydraulic cylinder 206, electric reel 208, scissor lift mechanism 106, and electric wheel 302. All collected data is transmitted to the calculation module of the control console 103. The calculation module compares the real-time data with preset safety thresholds and operating parameters to accurately determine whether the equipment is in normal operating condition. If safety hazards such as the movable pin 105 not being locked or the electric outrigger 304 not being fully grounded are detected, the calculation module will quickly determine it as an abnormal state and immediately output a locking command to stop the relevant actions of the scissor lift mechanism 106 or the boom assembly 2. If the lifting weight exceeds the preset threshold or the remaining battery power is lower than the preset threshold, the calculation module will simultaneously output an alarm command and a locking command, locking the lifting action of the boom assembly 2 while issuing an alarm. If the real-time data meets the preset requirements, the calculation module will accurately allocate control signals according to the instructions input by the operator and the real-time status of each component, driving the corresponding components such as the electric wheel 302, electric outrigger 304, and scissor lift mechanism 106 to complete a series of actions such as movement, support, lifting, and hoisting, ensuring that each component operates in coordination, thus ensuring operational safety and improving operational accuracy and efficiency.

[0048] Working Principle: This device relies on the coordinated operation of the lifting platform assembly and chassis assembly to achieve equipment movement, stable support, and working height adjustment. The control console 103 serves as the control core of the entire device, establishing electrical connections with all electrical and hydraulic components to achieve centralized control of the entire process. Before operation, the electric wheels 302 of the chassis assembly 3 can be driven by the control console 103. The electric wheels 302 drive the base 301 and the lifting platform assembly 1 and the straight boom assembly 2 above it to the designated construction position. After reaching the position, the control console 103 adjusts the placement direction of the extension arm 303, and then drives the electric outriggers 304 to extend downwards and firmly contact the ground. The electric outriggers 304 lift the base 301 as a whole, causing the electric wheels 302 to leave the ground, providing a stable working support foundation for the device. Construction workers can ascend to the lifting platform 101 via the ladder 110. After closing the movable door 104 behind the guardrail 102 and locking the movable latch 105, they can issue a command through the control console 103 to drive the scissor lift mechanism 106 to extend and retract. One end of the scissor lift mechanism 106 is fixed to the upper surface of the base 301, and the other end is movably connected to the lower surface of the lifting platform 101. Its extension and retraction can drive the lifting platform 101 to rise and fall smoothly to the preset working height. The guardrail 102 provides safety protection for construction workers on the lifting platform 101. The battery pack in the battery compartment 107 provides independent and continuous power to all electrical components of the entire device. The storage compartment 108 can store construction tools and small materials. The protective plate 109 can effectively prevent personnel from accidentally touching the active area of ​​the scissor lift mechanism 106, ensuring personnel safety during operation.

[0049] The hoisting function of this device is achieved independently by the straight boom crane assembly 2, and is adapted to the working height of the lifting platform assembly 1, which can complete the precise transfer of materials from the ground or external area to the working area of ​​the lifting platform 101. After the control console 103 issues a hoisting command, the electric slider 202 can move linearly back and forth along the slide rail 201 fixed on the upper surface of the lifting platform 101, realizing the lateral position adjustment of the entire boom crane assembly 2; the rotary box 203 moves synchronously with the electric slider 202, and can make horizontal rotation, driving the upper support column 204 and subsequent hoisting components to adjust the horizontal direction and accurately align with the material to be hoisted; the support column 204 provides load-bearing support for the hoisting components of the entire boom crane assembly 2, and the control console 103 can drive the telescopic arm 205 to make telescopic movements, changing the horizontal extension distance of the boom crane assembly 2. At the same time, the two ends of the hydraulic cylinder 206 are respectively hinged to the support column 204 and the telescopic arm 205. When the hydraulic cylinder 206 makes telescopic movements, it can drive the telescopic arm 205 to make pitch movements around the hinge point with the support column 204; Once the hook 210 is positioned directly above the material to be lifted, the control console 103 drives the electric reel 208 inside the support column 204 to rotate forward, releasing the steel cable 209 wound around its outer surface. The steel cable 209 changes direction by passing around the sliding wheel 207 movably mounted on the outer surface of the front of the telescopic boom 205, causing the hook 210 to descend smoothly and hook the material. Subsequently, the electric reel 208 rotates in the reverse direction, winding up the steel cable 209 and lifting the material vertically. The control console 103 then adjusts the coordinated actions of the electric slider 202, the rotary box 203, the telescopic boom 205, and the hydraulic cylinder 206 to precisely lift the material to the working area of ​​the lifting platform 101, completing the entire material transfer process. The motion accuracy of the entire lifting process can be precisely controlled by the control console 103, adapting to the lifting needs of materials in different positions and of different specifications.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention 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 invention should be included within the protection scope of the present invention.
