[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a multi-functional support device for high-altitude work safety, including a base 1, a lifting assembly on the top of the base 1, and an operating platform 10 on the top of the lifting assembly. This allows the device to meet the work requirements at different heights. Through the operation of the lifting assembly, the height of the operating platform 10 can be precisely adjusted to meet the requirements of different working heights in high-altitude work, providing a suitable working plane for workers. Two protective railings 11 are slidably connected to the top of the operating platform 10, which can effectively prevent workers from accidentally falling from the edge of the operating platform 10 when they are working at height. Two guardrails 12 are slidably connected to the top of the operating platform 10. The guardrails 12 can also slide on the top, and cooperate with the protective railings 11 to further strengthen the protection around the operating platform 10, ensuring the safety of workers in all aspects. The guardrails 12 are fixedly connected to the outside with multiple buckles 13 to ensure that the guardrails 12 will not shake or shift during use.
[0033] Fixed blocks 14 are fixedly connected to both sides of the operating table 10. A handle 17 is rotatably connected to the outside of the fixed block 14. A slide rod 15 is rotatably connected to the inner wall of the handle 17. Locks 16 are fixedly connected to both ends of the slide rod 15. The fixed blocks 14 provide an installation base for the handle 17, ensuring that the handle 17 can be stably connected to both sides of the operating table 10 and can rotate flexibly. The lock 16 can slide into or out of the buckle 13 under the drive of the slide rod 15, realizing the locking and unlocking of the fence 12 and the protective fence 11, ensuring the stability of the protective structure. The handle 17 can rotate around the fixed block 14, which is convenient for the operator to operate. By rotating the handle 17, the slide rod 15 and the lock 16 connected to it can be driven to perform corresponding actions. The slide rod 15 can move horizontally under the drive of the handle 17, thereby controlling the position of the lock 16 to achieve the purpose of connecting or separating from the buckle 13. There are support components on both sides of the base 1.
[0034] The outer wall of the latch 16 is slidably connected to the outer walls of the two buckles 13. When the operator pulls up the handle 17, the latch 16 can accurately slide into the outer wall slot of the buckle 13 under the action of the slide bar 15, so as to securely lock the fence 12 and prevent the fence 12 from being loosened accidentally. The outer wall of the buckle 13 is slidably connected to the inner wall of the operating table 10. This design allows the fence 12 to slide along the inner wall of the operating table 10, while ensuring that the buckle 13 can be stably connected to the operating table 10 when it is engaged with the latch 16.
[0035] A handle 25 is rotatably connected to the inner wall of the base 1. The handle 25 allows the operator to easily push or pull the device by rotating the handle 25, using the lever principle, when the device is moved. This facilitates the adjustment of the device's position on the construction site. Four pulleys 24 are fixedly connected to the bottom of the base 1. The pulleys 24 enable the device to move easily on the ground, reducing friction during movement, improving the device's mobility, and making it easy for operators to quickly move the device to the required work location.
[0036] Reference Figure 1 and Figure 3 The support assembly includes connecting blocks 18. Multiple connecting blocks 18 are externally fixed to both sides of the base 1. The connecting blocks 18 provide connection points for other components of the support assembly, enabling the entire support assembly to be stably installed on both sides of the base 1. Connecting plates 19 are rotatably connected to the outer walls of two connecting blocks 18. The connecting plates 19 can rotate around the connecting blocks 18. Support plates 21 are rotatably connected to the other ends of the two connecting plates 19. The support plates 21 can be unfolded or retracted under the drive of the connecting plates 19. When unfolded, they provide a larger support area for the entire device and enhance the stability of the device during operation. A pneumatic cylinder 20 is rotatably connected to the outer wall of the base 1. The pneumatic cylinder 20 serves as a power source and can provide driving force for the rotation of the connecting plates 19. By changing the air pressure, the rotation angle of the connecting plates 19 can be precisely controlled. The other end of the pneumatic cylinder 20 is rotatably connected to the inner wall of the connecting plates 19. This connection method enables the pneumatic cylinder 20 to effectively transmit power to the connecting plates 19, driving the connecting plates 19 to rotate in the expected direction and angle.
[0037] A clamping block 22 is rotatably connected to the bottom of the support plate 21. The clamping block 22 can rotate around the connection point at the bottom of the support plate 21, allowing the clamping block 22 to automatically adjust its angle according to the ground conditions when the support plate 21 contacts different ground surfaces. A pad 23 is fixedly connected to the bottom of the clamping block 22. The pad 23 increases the contact area with the ground, and due to the rotatable design of the clamping block 22, the pad 23 can better conform to ground surfaces with different slopes, providing more stable support for the device.
[0038] Reference Figures 1 to 3 The lifting assembly includes a rotating rod 2, with both ends of the rotating rod 2 slidably connected to the inner wall of the base 1. The inner wall of the base 1 has a sliding groove 5. The rotating rod 2 slides in the sliding groove 5 of the inner wall of the base 1, providing a basic moving track for the operation of the entire lifting assembly and ensuring its stability during the lifting process. A pneumatic rod 3 is fixedly connected to the outside of the rotating rod 2. The driving end of the pneumatic rod 3 is fixedly connected to a rotating rod 4. The pneumatic rod 3 serves as the power driving component of the lifting assembly. By changing the internal air pressure, it pushes the rotating rod 4 to move, thereby realizing the lifting action of the entire lifting assembly. Under the drive of the pneumatic rod 3, the rotating rod 4 can slide along the sliding groove 5 of the inner wall of the base 1 to adjust the height of the operating platform 10.
[0039] A driven plate 7 is rotatably connected to the outer wall of the rotating rod 2 4. Driven by the rotating rod 2 4, the driven plate 7 can rotate around the connection point. A follower plate 6 is rotatably connected to the outer wall of the rotating rod 2. The follower plate 6 moves with the rotation of the rotating rod 2. A driven plate 9 is rotatably connected to the other end of the follower plate 6. The follower plate 9 moves under the drive of the follower plate 6. Its other end is connected to the operating table 10. It realizes the lifting and lowering operation of the operating table 10 through its own movement. A follower plate 8 is rotatably connected to the other end of the driven plate 7. Driven by the driven plate 7, the follower plate 8 transmits the movement to the operating table 10, realizing the smooth and precise lifting and lowering control of the operating table 10. The other end of the follower plate 8 is rotatably connected to the bottom of the operating table 10. This connection method allows the follower plate 8 to directly apply force to the operating table 10, realizing the stable lifting and lowering of the operating table 10.
[0040] On the other side of the protective fence 11, there are two hinges 26 threadedly connected. The hinges 26 are threadedly connected to the protective fence 11 to ensure the stability of the connection and provide a connection basis for the rotation of the enclosure 27. The other side of the two hinges 26 is threadedly connected to the enclosure 27. The enclosure 27 is connected to the protective fence 11 through the hinges 26. The workers can easily pull open the enclosure 27 to enter the operating platform 10 by rotating the hinges 26. The enclosure 27 can be closed during operation to enhance the protective effect.
[0041] The other end of the driven plate 2 9 is slidably connected to the inner wall of the operating table 10. During the sliding process, the driven plate 2 9 can accurately control the lifting and lowering action of the operating table 10, ensuring the stability and accuracy of the operating table 10 during the lifting and lowering process.
[0042] Working principle: The device is placed on the working surface and the pneumatic cylinder 20 is activated. The connecting plate 19 is lowered and the support plate 21 falls down. The bottom clamping block 22 is connected to the pad plate 23 to adapt to different slopes and provide better support. The force on the working platform can be distributed to more support points and closely fit the ground to maintain overall stability and avoid the support device from shaking due to uneven ground.
[0043] After placing the device, align the safety railing 11 with the buckle 13 on the fence 12, insert the safety railing 11 and fence 12 into the operating platform 10, pull up the handle 17 to engage the lock 16 with the buckle 13, and secure it. Workers can then pull open the enclosure 27 and enter the operating platform 10 to work, facilitating regular and comprehensive maintenance and inspection. This allows for the timely detection and replacement of worn and aging parts, ensuring the equipment is always in good operating condition and reducing safety accidents caused by equipment malfunctions.
[0044] Finally, it should be noted that the above description is only 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.
