[0033] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0034] According to the specific embodiments of the present invention, Figure 1-4 As shown, the present invention provides a high bridge pier rapid assembly protection operation platform device, the platform device comprises:

[0035] The cross beams 2 are arranged in parallel with each other, and the cross beams 2 span the top of the pier body 1 .

[0036] Vertical rods 3: Both ends of each cross beam 2 are connected with a vertical rod 3, and the vertical rod 3 extends in the vertical direction.

[0037] The annular platform 4 surrounds the outer periphery of the pier body 1 , and the bottom end of each vertical rod 3 is connected to the outer side of the annular platform 4 .

[0038] The anti-falling support mechanism 5 , wherein a plurality of anti-falling support mechanisms 5 are evenly distributed on the inner side of the annular platform 4 , and the anti-falling support mechanism 5 is located between the annular platform 4 and the pier body 1 .

[0039] In the platform device, by arranging the cross beam 2 on the top of the pier body 1 and using the pier body 1 to support the platform device, it is possible to simplify the structure of the platform device more conveniently, and vertical rods 3 are installed at both ends of the cross beam 2, and the bottom ends of the vertical rods 3 are connected to the outer side of the annular platform, so that the platform device can be quickly assembled, which is convenient for improving the installation efficiency of the platform device; and a plurality of anti-fall support mechanisms 5 are arranged on the inner side of the annular platform 4, and the anti-fall support mechanisms 5 are abutted between the annular platform 4 and the pier body 1, so as to support the annular platform and prevent the annular platform from falling quickly, so that the platform device can be used more stably and reliably, and the platform device has better safety.

[0040] The anti-fall support mechanism 5 includes an upper support rod 51 and a lower support rod 52. One end of the upper support rod 51 is hinged to the inner top surface of the annular platform 4, and the other end is against the pier body 1; one end of the lower support rod 52 is hinged to the inner bottom surface of the annular platform 4, and the other end is against the pier body 1.

[0041] A tension spring 53 is provided between the upper support rod 51 and the lower support rod 52. In one embodiment of the present application, under the action of the tension spring 53, one end of the upper support rod 51 and one end of the lower support rod 52 are firmly pressed against the pier body 1, thereby increasing the friction force between the upper support rod 51, the lower support rod 52 and the pier body 1. On the one hand, the anti-falling support mechanism 5 can play a certain supporting role on the annular platform 4 by pressing against the pier body 1; on the other hand, when the cross beam 2 is damaged and the annular platform 4 falls, a large friction force is generated between the upper support rod 51, the lower support rod 52 and the pier body 1, thereby slowing down the speed and trend of the annular platform 4 falling, and playing a better role in preventing the annular platform 4 from falling.

[0042] A first limiting rod 54 is provided between the upper support rod 51 and the lower support rod 52, one end of the first limiting rod 54 is hinged to the upper support rod 51, and the other end is hinged to the lower support rod 52. In one embodiment of the present application, the first limiting rod 54 is used to limit the opening angle between the upper support rod 51 and the lower support rod 52 to prevent the opening angle between the upper support rod 51 and the lower support rod 52 from being too large, thereby preventing the tension spring 53 from being deformed by pulling and exceeding its own elastic travel to cause damage.

[0043] A second limiting rod 55 is provided between the lower support rod 52 and the bottom of the annular platform, one end of the second limiting rod 55 is hinged to the lower support rod 52, and the other end is hinged to the bottom of the annular platform 4. In one embodiment of the present application, a triangular stable structure is formed between the second limiting rod 55, the annular platform, and the lower support rod 52, and a triangular stable structure is formed between the upper support rod 51, the lower support rod 52, and the first limiting rod 54, which strengthens the overall stability of the anti-falling support mechanism 5, so that one end of the upper support rod 51 and the lower support rod 52 can be more stably pressed against the pier body 1, thereby ensuring that there is sufficient friction between the anti-falling support mechanism 5 and the pier body 1.

[0044] The first limiting rod 54 and the second limiting rod 55 are both hydraulic damping rods. In one embodiment of the present application, the first limiting rod 54 and the second limiting rod 55 are both configured as hydraulic damping rods, so that the upper support rod 51 and the lower support rod 52 can be fine-tuned with each other during the falling process, so that one end of the upper support rod 51 and the lower support rod 52 can better fit against the pier body 1.

[0045] The platform device also includes a pressure equalizing mechanism 6, and a plurality of pressure equalizing mechanisms 6 are evenly distributed on the inner side of the annular platform 4, and the pressure equalizing mechanism 6 is located between the annular platform 4 and the pier body 1; and the pressure equalizing mechanism 6 and the anti-falling support mechanism 5 are alternately arranged. In one embodiment of the present application, the pressure equalizing mechanism 6 and the anti-falling support mechanism 5 are alternately arranged between the annular platform 4 and the pier body 1, and by arranging the pressure equalizing mechanism 6, the annular spacing between the annular platform 4 and the pier body 1 is made as uniform as possible, so that the stress state of each anti-falling support mechanism 5 is kept as consistent as possible, thereby ensuring that the overall stress of the platform device is more uniform, and the use state is more stable and reliable.

[0046] The pressure equalizing mechanism 6 includes a guide cylinder 61, the bottom plate of which is fixed on the inner side of the annular platform 4; a guide rod 63 is provided inside the guide cylinder 61 for guiding movement, a compression spring 62 is provided between the bottom end of the guide rod 63 and the bottom plate of the guide cylinder 61, and a roller 64 is rotatably provided at the front section of the guide rod 63, and the roller 64 rests on the pier body 1.

[0047] In one embodiment of the present application, under the action of the compression spring 62, the guide rod 63 pushes the roller 64 forward so that the roller 64 is pressed tightly against the pier body 1, so that the pressure equalizing mechanism 6 can be suitable for pier bodies 1 of different radial sizes; and multiple pressure equalizing mechanisms 6 are evenly arranged around the pier body 1 on the inner side of the annular platform 4, so that the distance between each position on the inner side of the annular platform 4 and the pier body 1 can be kept as consistent as possible, thereby ensuring that the force on the entire platform device is more uniform and stable during use.

[0048] The upper support rod 51 and the lower support rod 52 are both hinged with a support seat at one end close to the pier body 1. In one embodiment of the present application, the ends of the upper support rod 51 and the lower support rod 52 are hinged with the support seat, which not only makes the platform device applicable to pier bodies 1 of different sizes, but also when the platform device falls, the support seats on the upper support rod 51 and the lower support rod 52 can fit well on the pier body 1.

[0049] The annular platform 4 is a frame structure 41, and a plurality of platform plates 42 are laid inside the frame structure 41. In one embodiment of the present application, when installing the annular platform 4, the frame structure 41 is first assembled on the periphery of the pier body 1, and then the outer side of the frame structure 41 is connected and fixed to the bottom end of the vertical rod 3, and finally the platform plates 42 are laid on the frame structure 41 to form the annular platform 4, which facilitates the rapid installation and construction of the platform device to improve the construction efficiency.

[0050] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
