Description

Technical Field

[0001] This utility model belongs to the field of lighthouse equipment technology, specifically relating to a lighthouse lifting device. Background Technology

[0002] Solar-powered lighthouses, as core equipment for new energy outdoor lighting, convert solar energy into electricity through photovoltaic panels and store it in batteries to provide continuous nighttime illumination. They are widely used in various scenarios. During the installation, maintenance, and component replacement of lighthouses, lifting devices are crucial for the precise hoisting of heavy components.

[0003] A lifting device with announcement number CN220664631U, although improving lifting balance by optimizing the center of gravity of the lifting device components, still has significant defects: its lifting device components are only connected to the top of the motor unit housing at a single point through the connecting bracket, resulting in concentrated stress points and insufficient structural rigidity, causing significant shaking of the device when lifting large loads; moreover, it lacks multi-dimensional reinforcement measures, which can easily lead to fatigue cracking at the connection points after long-term use, making it difficult to guarantee lifting accuracy and seriously affecting the safety and efficiency of lighthouse installation. Utility Model Content

[0004] The purpose of this invention is to provide a lighthouse lifting device to solve the technical defects of existing lighthouse lifting devices, which are prone to insufficient structural rigidity due to concentrated force at a single point and pose safety hazards when lifting heavy loads.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A lighthouse lifting device includes a lifting assembly, a housing, and a support assembly. The lifting assembly is mounted on the housing, and the housing is mounted on the support assembly.

[0007] The lifting assembly includes a support frame, a connecting frame, and a lifting connector. The bottom end of the support frame passes through the inner cavity of the box and is fixed. The connecting frame is fixed to the top of the outer surface of the support frame. The bottom of the connecting frame fits against the top of the box. The lifting connector is located at the top of the connecting frame.

[0008] Both the support frame and the connecting frame are L-shaped, and the two sides of the support frame are attached to the right angle of the inner wall of the box. The three are welded together to form a triangular support structure.

[0009] As a further embodiment of this utility model, a support plate is fixedly connected to the top of the connecting frame and is arranged perpendicularly to it, and a lifting connector is located on the top of the support plate.

[0010] As a further embodiment of this utility model, the lifting connector includes a base plate fixed to the top of the pallet, a support plate welded to the top of the base plate and arranged perpendicularly to it, and a lifting hole opened on the surface of the support plate for connecting external lifting equipment.

[0011] As a further embodiment of this utility model, a first reinforcing plate is welded together between the base plate and the support plate, and two first reinforcing plates are symmetrically arranged on both sides of the support plate.

[0012] As a further embodiment of this utility model, at least two second reinforcing plates are horizontally fixed on the inner wall surfaces of the support frame and the connecting frame in the vertical direction, and a third reinforcing plate is vertically fixed between the inner wall of the connecting frame and the bottom of the support plate.

[0013] As a further embodiment of this utility model, the top and bottom of the box are provided with through holes for the support frame to pass through. The shape of the through holes is adapted to the cross-section of the support frame and is in the form of an L-shape. The L-shaped opening direction of the through holes is consistent with the bending direction of the support frame to accommodate its through installation.

[0014] As a further preferred embodiment of this utility model, the support component includes a support platform fixedly connected to the bottom of the box, and a base fixedly connected to the bottom of the support platform.

[0015] Compared with existing technologies, the lighthouse lifting device provided by this utility model has the following advantages:

[0016] This device, through the integrated design of the lifting components and the housing, utilizes the triangular support structure formed by the L-shaped support frame and the inner wall of the housing to transform the traditional single-point force-bearing mode into three-dimensional surface load transmission, solving the swaying and displacement problems caused by single-point connection of lifting components in existing technologies. This structural design improves the device's anti-overturning performance during lifting operations, effectively avoiding structural deformation caused by uneven force distribution and ensuring the safety of the lifting process. The L-shaped support frame's fixation method through the housing and the stepped layout of the connecting frame form a short-path, low-loss force transmission system. The load is directly distributed to the right-angled wall of the housing through the transmission path of the lifting connectors, pallets, connecting frames, and support frames. Compared with the indirect force transmission method through the motor housing in existing technologies, stress concentration is reduced, ensuring load balance during the lifting of heavy components of the lighthouse.

Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0028] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, an integral connection, or a detachable connection; they can refer to the internal connection of two components; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0029] See appendix Figures 1-4As shown, the lighthouse lifting device of this utility model embodiment includes a lifting assembly 100, a housing 200, and a support assembly 300. The lifting assembly 100 is mounted on the housing 200, and the housing 200 is mounted on the support assembly 300. The lifting assembly 100 includes a support frame 110, a connecting frame 120, and a lifting connector 130. The bottom end of the support frame 110 penetrates through the inner cavity of the housing 200 and is fixed thereto. The connecting frame 120 is fixed to the top end of the outer surface of the support frame 110, and the bottom end of the connecting frame 120 is fitted against the top end of the housing 200. The lifting connector 130... Located at the top of the connecting frame 120; both the support frame 110 and the connecting frame 120 are L-shaped structures, and the two sides of the support frame 110 are attached to the right angle of the inner wall of the box 200. The three are welded together to form a triangular support structure. The lifting load is distributed to the wall of the box 200 through the triangular support structure. The overall structural strength is significantly improved by utilizing the principle of geometric stability. Compared with the traditional single-point connection method, it effectively reduces swaying and displacement during lifting. The close welding design of the L-shaped structure and the box 200 optimizes the load transfer path and reduces stress concentration.

[0030] When the lighthouse lifting device of the above technical solution is used, the external lifting equipment applies the load through the lifting hole 133, the support plate 132 transmits the force to the base plate 131, the support plate 121 is connected to the connecting frame 120, the L-shaped support frame 110 and the connecting frame 120 decompose the load into vertical and horizontal components, and the triangular support structure disperses the force to the wall of the box 200. By utilizing the principle of triangle stability, the single-point load is transformed into a surface load, which improves the structure's anti-overturning ability. The bending angle of the L-shaped structure is reasonably designed to ensure that the force line is consistent with the direction of the material fiber, reducing shear stress. The high-strength alloy material ensures safety redundancy under rated load. The reasonable selection of welding process and bolt connection eliminates assembly gaps, avoids fretting wear, and ensures connection strength. The layout of each reinforcing plate is optimized to avoid the resonance frequency during lifting, reduce vibration amplitude, and ensure lifting safety.

[0031] The top of the connecting frame 120 is fixedly connected to a support plate 121 that is perpendicular to it. The lifting connector 130 is located on the top of the support plate 121. The support plate 121 provides a horizontal mounting reference surface for the lifting connector 300, ensuring the verticality of the lifting hole 133, preventing the device from tilting due to eccentric load during lifting, and improving the stability of the lifting operation.

[0032] The lifting connector 130 includes a base plate 131 fixed to the top of the support plate 121. A support plate 132 is welded to the top of the base plate 131 and is perpendicular to it. The surface of the support plate 132 is provided with a lifting hole 133 for connecting external lifting equipment. The vertical structure of the base plate 131 and the support plate 132 forms a rigid connection. The lifting hole 133 can be directly adapted to mainstream hooks on the market, which facilitates connection with external lifting equipment and improves work efficiency.

[0033] Specifically, in this embodiment: a first reinforcing plate 134 is welded together between the base plate 131 and the support plate 132. Two first reinforcing plates 134 are symmetrically arranged on both sides of the support plate 132. The first reinforcing plates form a triangular reinforcing rib structure, which enhances the deformation resistance of the lifting connector 300, reduces stress concentration, and extends the service life of the component.

[0034] At least two second reinforcing plates 140 are horizontally fixed to the inner wall surfaces of the support frame 110 and the connecting frame 120 in the vertical direction. A third reinforcing plate 150 is vertically fixed between the inner wall of the connecting frame 120 and the bottom of the support plate 121. The central axis of the third reinforcing plate 150 coincides with the central axis of the support plate 121. The multi-layered second reinforcing plates 140 and the third reinforcing plates 150 cooperate to form a three-dimensional support network, which improves the overall rigidity of the device and ensures the structural safety of each component under lifting load.

[0035] Both the top and bottom of the housing 200 are provided with through holes 210 for the support frame 110 to pass through. The shape of the through hole 210 is adapted to the cross-section of the support frame 110, and is in the form of an L-shape. The L-shaped opening direction of the through hole 210 is consistent with the bending direction of the support frame 110 to accommodate its through installation. The L-shaped through hole 210 is precisely adapted to the support frame 110, reducing installation errors, reducing vibration and noise caused by assembly gaps, and enhancing the sealing performance of the housing 200.

[0036] The support assembly 300 includes a support platform 310 fixedly connected to the bottom of the housing 200, and a base 320 fixedly connected to the bottom of the support platform 310. The design of the support platform 320 and the base 310 evenly distributes the load of the housing 200. The base can be installed on the upper tractor to facilitate the movement of the device and meet the requirements of rapid deployment.

[0037] This utility model embodiment of the lighthouse lifting device, through the integrated design of the lifting component 100 and the housing 200, utilizes the triangular support structure formed by the L-shaped support frame 110 and the inner wall of the housing 200 to transform the traditional single-point force-bearing mode into three-dimensional surface load transmission, solving the swaying and displacement problems caused by the single-point connection of the lifting components in the prior art; it improves the anti-overturning performance during lifting operations, effectively avoids structural deformation caused by uneven force, and ensures the safety of the lifting process; the L-shaped support frame 110 penetrates the housing 200 through the fixed method and the stepped layout of the connecting frame, forming a short-path, low-loss force transmission system; the load is directly distributed to the right-angled wall of the housing 200 through the transmission path of the lifting connector 130, the pallet 121, the connecting frame 120, and the support frame 110, compared with the indirect force transmission method through the motor housing in the prior art, stress concentration is reduced, ensuring the load balance during the lifting of heavy lighthouse components.
