Description

Technical Field

[0001] This utility model belongs to the field of lighthouse technology, specifically a safety support mechanism for raising and lowering the light panel of a lighthouse. Background Technology

[0002] Currently, when installing the lifting light panel in a lighthouse, the only way to suspend it from the main body is by using a traction steel cable. However, this installation method is prone to the following problems: 1. The steel cable tractioning the light panel is under constant stress and lacks a supporting force, posing a significant safety hazard; 2. The light panel sways due to wind, and the traction of the steel cable cannot compensate for the swaying force, making it very easy for it to fall and cause a safety accident.

[0003] To address the aforementioned issues, a mounting bracket is typically installed on the main body of the lighthouse to secure the lifting light panel. However, this method requires the lifting light panel to be installed from the top of the lighthouse onto the bracket whenever it needs to be disassembled or installed, necessitating high-altitude work by the operator, which increases safety hazards and can also damage the lightning rod due to improper operation. Therefore, there is an urgent need to design a safety support mechanism for the lifting light panel of a lighthouse to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a safety support mechanism for a lighthouse lifting light panel, which solves the problems mentioned above, such as the existing lifting light panel being subjected to long-term traction by steel wire ropes, resulting in large stress on the steel wire ropes and causing significant safety hazards; the light panel lacking support and being unable to compensate for the swaying of the light panel due to excessive wind force, which easily leads to safety accidents; the difficulty in installing the lifting light panel on the mounting frame of the lighthouse body, which easily endangers personnel safety; and the easy damage to the lightning rod due to improper operation.

[0005] To solve the above-mentioned technical problems, this utility model provides a safety support mechanism for a lighthouse lifting panel, including a lifting assembly and a telescopic frame assembly mounted on the lighthouse body. The lifting end of the lifting assembly is connected to the lifting panel and pulls the lifting panel to move up and down on the outside of the lighthouse body.

[0006] The telescopic frame assembly includes a fixed frame, four supports, four telescopic brackets, a turntable, and a motor. The fixed frame is fixedly installed in the upper middle part of the lighthouse body. The four supports are respectively fixedly installed around the fixed frame. One end of each telescopic bracket passes through the corresponding support and the other end is connected to the turntable. The motor is fixedly installed on the fixed frame, and its output end extends out of the fixed frame and connects to the turntable. The fixed frame is provided with a rotation angle limiting component for limiting the rotation of the turntable. The motor drives the turntable to rotate, so that the four telescopic brackets simultaneously extend out of or retract into the supports to support or release the lifting light panel.

[0007] Furthermore, the lifting assembly includes a drive mechanism, four pulley frames, and a first pulley and a second pulley mounted on each of the pulley frames. The drive mechanism is located on the ground or the main body of the lighthouse and is a lift. The four pulley frames are symmetrically arranged on the top of the main body of the lighthouse. A steel wire rope is wound around the first pulley and the second pulley on each of the pulley frames. One end of each steel wire rope is connected to the lifting light panel, and the other end is connected to the lift.

[0008] Furthermore, the four telescopic brackets are arranged in pairs, and the two telescopic brackets in each pair are arranged perpendicularly to each other. The fixed frame is provided with two horizontal supports, and the two horizontal supports are respectively located between the two groups of horizontally arranged telescopic brackets.

[0009] Furthermore, the rotation angle limiting component includes a stop block and a first limit switch and a second limit switch respectively disposed on the two transverse supports. There are two stop blocks, each of which is disposed between the turntable and the connection point of the two telescopic brackets in each group. The contact rods of the first limit switch and the second limit switch are located on opposite sides of the two stop blocks and are used to contact the two stop blocks respectively.

[0010] Furthermore, each of the four inner corners of the lifting light panel is provided with guide wheels that can slide with the four outer corners of the fixing frame.

[0011] Furthermore, each of the telescopic brackets is formed by connecting a first connecting rod and a second connecting rod, and the second connecting rod is connected to the turntable by fasteners.

[0012] Furthermore, a third limit switch is provided on the outer wall of the main body of the lighthouse, which is used to limit the movement position of the lifting light panel.

[0013] Furthermore, the motor is a speed-regulating motor.

[0014] The beneficial effects of this utility model are as follows: The safety support mechanism of this utility model provides stable and reliable support with strong wind resistance. It supports or removes the lifting light panel through the telescopic frame assembly, so that the lifting light panel can be installed on the lighthouse body or lowered by the lifting assembly to remove the lifting light panel. This gives the safety support mechanism two functions, thereby improving the service life of the lifting light panel and the lighthouse body. It solves the problem that the existing lifting light panel is subjected to long-term traction by the steel wire rope, resulting in large stress on the steel wire rope and causing great safety hazards. It also solves the problem that the lifting light panel lacks support and cannot compensate for the sway of the lifting light panel when the wind is too strong, which can easily cause safety accidents.

[0015] The lifting assembly is designed so that the steel wire rope can slide on four pulley frames via a drive mechanism, thereby raising or lowering the lifting light panel to facilitate its installation and removal.

[0016] The rotation angle limiting component can effectively control the rotation angle and range of the turntable by setting a stop block between the turntable and the connection point of each set of two telescopic brackets, as well as a first limit switch and a second limit switch. This ensures that the telescopic bracket will not break as the turntable rotates after completing linear extension and retraction, thereby improving the service life and stability of the telescopic bracket assembly.

[0017] The four corner guide wheels inside the lifting light panel change the static friction between the lifting light panel and the fixed frame to dynamic friction, which can effectively reduce the wear rate between the lifting light panel and the fixed frame. At the same time, it can also guide the lifting light panel. In the event of strong winds, the guide wheels of the fixed frame and the lifting light panel can effectively compensate for the sway of the lifting light panel, allowing it to move up and down smoothly on the outside of the fixed frame, thereby improving the stability of the lifting light panel.

[0018] The third limit switch on the outer wall of the lighthouse body can effectively limit the highest position of the lifting light panel. When the lifting light panel reaches the lifting position, it sends a signal to the control unit. Upon receiving the signal, the control unit controls the lifting machine to stop working and then controls the motor to rotate so that the four telescopic brackets of the telescopic frame assembly extend to support the lifting light panel.

[0019] The variable speed motor allows for effective control of the turntable's rotation speed, thus effectively preventing the telescopic bracket from breaking due to inaccurate control of rotation speed and angle during bracket extension and retraction. Attached Figure Description

Detailed Implementation

[0024] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] The following will describe a specific embodiment of this utility model and its appendix. Figure 1-2 To explain in detail, a safety support mechanism for a lighthouse lifting panel is disclosed, including a lifting assembly 2 and a telescopic frame assembly 3 installed on the lighthouse body 1. The lifting end of the lifting assembly 2 is connected to the lifting panel 4 and pulls the lifting panel 4 to move up and down on the outside of the lighthouse body 1.

[0026] The telescopic frame assembly 3 includes a fixed frame 31, four supports 32, four telescopic brackets 33, a turntable 34, and a motor 35. The fixed frame 31 is fixedly installed in the upper middle part of the lighthouse body 1. The four supports 32 are respectively fixedly installed around the fixed frame 31. One end of each telescopic bracket 33 passes through the corresponding support 32, and the other end is connected to the turntable 34. The motor 35 is fixedly installed on the fixed frame 31, and its output end extends out of the fixed frame 31 and connects to the turntable 34. The fixed frame 31 is provided with a rotation angle limiting component 36 for limiting the rotation of the turntable 34. The motor 35 drives the turntable 34 to rotate, so that the four telescopic brackets 33 can simultaneously extend out of the support 32 or retract into the support 32 to support or release the support of the lifting light plate 4.

[0027] The lifting assembly 2 includes a drive mechanism, four pulley frames 22, and a first pulley 23 and a second pulley 24 mounted on each pulley frame 22. The drive mechanism is located on the ground or on the main body of the lighthouse 1 and is a lift. The four pulley frames 22 are symmetrically arranged on the top of the main body of the lighthouse 1. A steel wire rope 25 is wound around the first pulley 23 and the second pulley 24 on each pulley frame 22. One end of each steel wire rope 25 is connected to the lifting light panel 4, and the other end is connected to the lift.

[0028] The lifting assembly 2 is designed so that the steel wire rope 25 can slide on the four pulley frames 22 via the drive mechanism, thereby raising or lowering the lifting light panel 4 to facilitate the installation and maintenance of the lifting light panel 4.

[0029] The four telescopic brackets 33 are arranged in pairs, and the two telescopic brackets 33 in each pair are arranged perpendicularly to each other. The fixed frame 31 is provided with two horizontal supports 311, and the two horizontal supports 311 are respectively located between the two sets of horizontally arranged telescopic brackets 33.

[0030] The rotation angle limiting component 36 includes a stop block 361 and a first limit switch 362 and a second limit switch 363 respectively disposed on two transverse supports 311. There are two stop blocks 361, and each stop block 361 is disposed between the turntable 34 and the connection point of each set of two telescopic brackets 33. The contact rods of the first limit switch 362 and the second limit switch 363 are located on opposite sides of the two stop blocks 361 and are used to contact the two stop blocks 361 respectively.

[0031] The rotation angle limiting component 36 can effectively control the rotation angle and range of the turntable 34 by setting the stop block 361 between the turntable 34 and the connection point of each group of two telescopic brackets 33, as well as the first limit switch 362 and the second limit switch 363. This ensures that the telescopic brackets 33 will not break as the turntable 34 rotates after completing linear extension and retraction, thereby improving the service life and stability of the telescopic bracket assembly 3.

[0032] The outer dimensions of the fixed frame 31 are smaller than the inner dimensions of the lifting light panel 4. The four inner corners of the lifting light panel 4 are provided with guide wheels 41 that can slide with the four outer corners of the fixed frame 31. The setting of the guide wheels 41 at the four inner corners of the lifting light panel 4 changes the static friction between the lifting light panel 4 and the fixed frame 31 into dynamic friction, which can effectively reduce the wear rate between the lifting light panel 4 and the fixed frame 31. At the same time, it can also play a guiding role for the lifting light panel 4. In addition, when the wind is strong, the guide wheels 41 of the fixed frame and the lifting light panel 4 can effectively compensate for the sway of the lifting light panel 4, so that it can move up and down smoothly on the outside of the fixed frame 31, thereby improving the stability of the lifting light panel 4.

[0033] Each telescopic bracket 33 is formed by connecting a first connecting rod 331 and a second connecting rod 332, and the second connecting rod 332 is connected to the turntable 34 by fasteners.

[0034] A third limit switch 5 is provided on the outer wall of the lighthouse body 1. The third limit switch 5 is used to limit the movement position of the lifting light panel 4. The setting of the third limit switch 5 on the outer wall of the lighthouse body 1 can effectively limit the highest position of the lifting light panel 4. When the lifting light panel 4 reaches the lifting position, it sends a signal to the control unit. When the control unit receives the signal, it controls the lifting machine to stop working and then controls the motor 35 to rotate so that the four telescopic brackets 33 of the telescopic frame assembly 3 extend to support the lifting light panel 4.

[0035] Motor 35 is a speed-regulating motor. The speed-regulating motor is designed to effectively control the rotation speed of turntable 34, thereby effectively preventing the telescopic bracket 33 from breaking due to inaccurate control of rotation speed and rotation angle when the support 32 extends or retracts.

[0036] The safety support mechanism of this utility model provides stable and reliable support, strong wind resistance, and other properties. Furthermore, the telescopic frame assembly 3 supports or removes the support for the lifting light panel 4, allowing it to be installed on the lighthouse body 1 or lowered via the lifting assembly 2 for removal. This dual function of the safety support mechanism improves the service life of both the lifting light panel 4 and the lighthouse body 1. It solves the problem of existing lifting light panels 4 being subjected to long-term traction by steel wire ropes, resulting in significant safety hazards due to the high stress on the steel wire ropes. It also addresses the issues of insufficient support for the lifting light panel 4 and the inability to compensate for its swaying under strong winds, which can easily lead to safety accidents.

[0037] The working process of this utility model is as follows:

[0038] When the lifting light panel 4 needs to be installed, the lifting light panel 4 is placed on the outside of the lighthouse body 1, and the four sides of the lifting light panel 4 and the fixing frame 31 are placed opposite each other. One end of the four steel wire ropes 25 is evenly fixed on the periphery of the lifting light panel 4, and the other end is fixed to the drive mechanism. The control unit controls the motor 35 to rotate forward, so as to drive the turntable 34 to rotate. At the same time, the four telescopic brackets 33 of the telescopic frame assembly 3 are driven to retract into the support 32 until the first limit switch 362 contacts the stop block 361. After the control unit receives the position signal sent by the first limit switch 362, it controls the turntable 34 to stop rotating, and at this time the ends of the four telescopic brackets 33 are retracted into the support 32.

[0039] After the telescopic frame assembly 3 is adjusted, the drive mechanism drives the connected steel wire rope 25 to wind up, pulling the lifting lamp plate 4 at the other end of the steel wire rope 25 upward. When it rises to the fixed frame 31, the lifting lamp plate 4 moves upward from the outside of the fixed frame 31, and at the same time, the guide wheels 41 at the four inner corners of the lifting lamp plate 4 roll upward along the outer walls of the four outer corners of the fixed frame 31 to correct the position of the lifting lamp plate 4 and reduce friction between them. When the guide wheels 41 of the lifting lamp plate 4 roll away from the fixed frame 31, it continues to rise until the third limit switch 5. At this point, the third limit switch 5 sends a positioning signal to the control unit, which then controls the drive mechanism to stop running. The system sends a signal to control the motor 35 to start. The motor 35 reverses to drive the turntable 34 to reverse. The rotational force of the turntable 34 drives the four telescopic brackets 33 of the telescopic frame assembly 3 to extend from the support 32 until the stop block 361 contacts the second limit switch 363. After the control unit receives the positioning signal sent by the second limit switch 363, it controls the turntable 34 to stop rotating. At this time, the ends of the four telescopic brackets 33 extend out of the support 32. The lifting mechanism of the lifting assembly 2 then drives the wire rope 25 to release the rope so that the lifting lamp plate 4 falls onto the four telescopic brackets 33 to support the lifting lamp plate 4 and realize the installation of the lifting lamp plate 4.

[0040] When the lifting light panel 4 needs to be removed, the motor 35 is controlled to rotate forward by the control unit, so that the turntable 34 rotates accordingly. At the same time, the four telescopic brackets 33 of the telescopic frame assembly 3 retract into the support 32 until the first limit switch 362 contacts the stop block 361. After the control unit receives the positioning signal sent by the first limit switch 362, it controls the turntable 34 to stop rotating, and at this time the ends of the four telescopic brackets 33 retract into the support 32.

[0041] After the telescopic frame assembly 3 is adjusted, the drive mechanism drives the connected steel wire rope 25 to release the rope, so that the lifting light panel 4 at the other end of the steel wire rope 25 slowly descends. When it descends to the fixed frame 31, the lifting light panel 4 moves downward from the outside of the fixed frame 31. At the same time, the guide wheels 41 at the four corners of the inner part of the lifting light panel 4 roll downward along the outer wall of the four corners of the outer part of the fixed frame 31 to correct the position of the lifting light panel 4 and reduce the friction between them. When the lifting light panel 4 descends to the ground or a designated position, the control unit issues a command to stop the drive mechanism of the lifting assembly 2, so that the lifting light panel 4 can be stopped and repaired.

[0042] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
