Specific embodiments
[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0027] All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0028] Next, in conjunction with the attached Figure 1-6 The present utility model will be further described. In order to solve the problems existing in the background technology, the present application proposes a pneumatic flap mechanism for a maintenance platform. In the specific technical solution, it includes a limit seat body 1, a flap body 2, and a flap driving assembly 3.
[0029] Such as Figure 1-3As shown, a lower rotating shaft 4 penetrates through the side wall of the limit seat body 1. The lower rotating shaft 4 can connect the limit seat body 1 and the support frame 302. The flap driving assembly 3 is installed at the bottom of the limit seat body 1 and the flap body 2. The flap driving assembly 3 is used to flip the flap body 2. The flap driving assembly 3 includes a flap cylinder 301 and a support frame 302 fixedly installed at the bottom of the flap body 2. The flap cylinder 301 can push the first connecting rod 303. The support frame 302 can support the bottom of the flap body 2. The support frame 302 is sleeved outside the lower rotating shaft 4 and is clamped in the limit seat body 1. The telescopic end of the flap cylinder 301 is fixedly installed with the first connecting rod 303. The first connecting rod 303 can connect the flap cylinder 301 and the second connecting rod 304. The end of the first connecting rod 303 away from the flap cylinder 301 is rotatably installed with the second connecting rod 304 fixedly connected to the support frame 302. The second connecting rod 304 can connect the first connecting rod 303 and the support frame 302. After the flap cylinder 301 extends, it can push the first connecting rod 303. The first connecting rod 303 can push the second connecting rod 304. The second connecting rod 304 can push the support frame 302. The support frame 302 can rotate upward. The support frame 302 can drive the flap body 2 to flip upward. The fixed end of the flap cylinder 301 is fixedly installed with an upper rotating shaft 305. The upper rotating shaft 305 can connect the flap cylinder 301 and the cylinder support 306. The outside of the upper rotating shaft 305 is sleeved with the cylinder support 306. The cylinder support 306 can facilitate the limitation of the flap cylinder 301 through the upper rotating shaft 305.
[0030] The cylinder support 306 can fixedly limit the upper rotating shaft 305. The upper rotating shaft 305 can limit the fixed end of the flap cylinder 301. The fixed end of the flap cylinder 301 can only rotate around the upper rotating shaft 305. By starting the flap cylinder 301, the flap cylinder 301 extends to give a thrust to the first connecting rod 303. The first connecting rod 303 gives a thrust to the second connecting rod 304. The second connecting rod 304 is arranged obliquely downward. The end of the second connecting rod 304 connected to the first connecting rod 304 rotates downward. The second connecting rod 304 gives a thrust to the support frame 302. The support frame 302 is limited by the lower rotating shaft 4. After the support frame 302 receives the thrust, it rotates upward around the central axis of the lower rotating shaft 4. The support frame 302 drives the flap body 2 to flip upward, enabling the flap body 2 to stand upright and ensuring the safety of construction workers.
[0031] As Figure 2-4As shown in the figure, a buffer assembly 5 is installed at the bottom of the support frame 302. The buffer assembly 5 is used to reduce the impact force when the flap body 2 falls. The buffer assembly 5 includes a spring 501, a fixed plate 502 fixedly installed at the bottom of the support frame 302, and a buffer plate 503 located below the support frame 302. The spring 501 can buffer the force transmitted by the buffer plate 503. The fixed plate 502 can fix the spring 501. The buffer plate 503 can transmit the impact force. A first limiting cylinder 504 is fixedly installed on the side wall of the fixed plate 502 facing the buffer plate 503. A second limiting cylinder 505 fixedly installed on the side wall of the buffer plate 503 is inserted into the first limiting cylinder 504. The first limiting cylinder 504 and the second limiting cylinder 505 can prevent the spring 501 from tilting. The spring 501 is fixedly installed between the fixed plate 502 and the buffer plate 503 and is located inside the second limiting cylinder 505.
[0032] When the flap body 2 falls, the flap body 2 drives the support frame 302 to rotate downward. The support frame 302 drives the fixed plate 502 to rotate downward. The fixed plate 502 drives the spring 501 and the first limiting cylinder 504 to rotate downward. The spring 501 and the first limiting cylinder 504 drive the buffer plate 503 and the second limiting cylinder 505 to rotate downward respectively. The buffer plate 503 hits the side wall of the bottom support 7. After the buffer plate 503 receives the impact force, it is transmitted to the spring 501. After the spring 501 receives the impact force, it contracts. The contraction of the spring 501 can weaken the received impact force. The spring 501 transmits the weakened force to the fixed plate 502. The fixed plate 502 receives a smaller force. The fixed plate 502 transmits the smaller force to the flap body 2 through the support frame 302. The flap body 2 will not directly receive a large impact force, which can protect the flap body 2.
[0033] As Figure 6 shown in the figure, a fixed frame 6 is fixedly installed above the cylinder support 306. The fixed frame 6 can support the limit seat body 1, the cylinder support 306 and the bottom support 7. The limit seat body 1 is fixedly connected to the fixed frame 6.
[0034] As Figure 6 shown in the figure, the bottom support 7 is fixedly installed on the side wall of the fixed frame 6. The bottom support 7 can support the bottom of the limit seat body 1, which is convenient for increasing the stability of the limit seat body 1. The bottom support 7 is fixedly installed below the limit seat body 1. The first connecting rod 303 and the second connecting rod 304 are located inside the limit seat body 1.
[0035] As Figure 6 shown in the figure, a through hole 8 aligned with the bottom support 7 is opened on the side wall of the fixed frame 6. The through hole 8 can connect the two sides of the fixed frame 6, which is convenient for the flap cylinder 301 to pass through the side wall of the fixed frame 6 and be connected to the first connecting rod 303. The telescopic end of the flap cylinder 301 is inserted into the through hole 8.
[0036] As Figure 3As shown in the figure, a reinforcing plate 9 fixedly connected to the fixing frame 6 is fixedly installed on the top of the limit seat body 1. The reinforcing plate 9 can strengthen the strength of the limit seat body 1 and increase the compressive resistance of the limit seat body 1.
[0037] As Figure 3 shown in the figure, the flap cylinder 301 conveys the air source through the air pipe as the power source for startup. The air source conveys the power gas to the flap cylinder 301 through the air pipe, which can facilitate the startup of the flap cylinder 301.
[0038] As Figure 6 shown in the figure, the fixing frame 6 is used to support the limit seat body 1, the cylinder support 306 and the bottom support 7, which can increase the stability of the turning plate mechanism.
[0039] As Figure 6 shown in the figure, the through hole 8 is used for connecting the flap cylinder 301 and the first connecting rod 303, which is convenient for the flap cylinder 301 to push the first connecting rod 303.
