[0026] The automatic transmission and intelligent early warning rotating bridge support device 6 comprises an upper barrel ring plate 7, an intermediate plate 8 and a lower barrel ring plate 9, wherein an intermediate plate 8 is provided between the upper barrel ring plate 7 and the lower barrel ring plate 9, a lower barrel ring plate sealing plate 10 is provided at the bottom end of the lower barrel ring plate 9, a pressure sensor 11 is welded at the bottom end of the lower barrel ring plate 9, a slide plate 12 is provided at the bottom end of the pressure sensor 11, the slide plate 12 is welded to the bottom end of the pressure sensor 11 and reinforcing angle plates 13 are provided at the four corners.

A switch wireless transmitter 16 is installed in the gap between the web 14 and the lower barrel ring plate 9. The switch wireless transmitter 16 is connected to the pressure sensor 11 by cable.

[0028] By setting a slide plate 12 at the bottom of each set of automatic transmission and intelligent early warning rotating bridge support device 6, each set of pressure sensors 11 is connected to the switch wireless transmitter 16 (model: H170-1U-8LAN) cable, and the data is projected and read on the mobile phone or each large display screen according to the code through the transmitter. The data is set according to the early warning and alarm limit, and the stress state is reflected by the size of the displayed value, and different representative colors and different audios are used for early warning / alarm prompts. When the limit is reached, the system automatically transmits information to the person in charge, and effective measures are taken in time. At the same time, in the process of box beam casting, prestressed construction of beam body, bracket system or hanging basket unloading / dropping, etc., the stress fluctuations can be automatically transmitted and automatically warned, which can timely reflect the stress state of the automatic transmission and intelligent early warning rotating bridge support device 6, and effectively improve the risk prevention and control capabilities of bridge rotation.

[0029] C55 slightly expanded epoxy concrete 15 is poured into the upper barrel ring plate 7 and the lower barrel ring plate 9.

[0030] By pouring C55 micro-expanding epoxy concrete 15 into the upper barrel ring plate 7 and the lower barrel ring plate 9, the C55 micro-expanding epoxy concrete 15 can make the concrete expand during the hardening process, thereby densely filling the upper barrel ring plate 7 and the lower barrel ring plate 9 to enhance the overall rigidity.

[0031] An external jack reaction seat 5 is provided on one side of the automatic transmission and intelligent early warning rotating bridge support device 6, and an internal jack reaction seat 4 is provided on the other side of the automatic transmission and intelligent early warning rotating bridge support device 6.

[0032] The top surface of the lower turntable 1 is provided with a slideway 17 , which is matched with the slide plate 12 .

[0033] By matching the slideway 17 with the skateboard 12, the skateboard 12 and the slideway 17 are dense before the weighing test node. When the beam is unevenly stressed during construction, the rotating bridge support device 6 is supported and balanced through automatic transmission and intelligent early warning to prevent the beam from overturning; when the rotating beam rotates, a gap is left between the skateboard 12 and the slideway 17, and the gap is filled with polytetrafluoroethylene skateboard and butter. When the beam rotates with balanced force, the skateboard 12 drags the polytetrafluoroethylene skateboard to rotate to the designed position; when the beam rotates with slight force, the polytetrafluoroethylene skateboard and butter are used to reduce friction between the skateboard 12 and the slideway 17, and the beam is rotated to the designed position; when the beam rotates with severe force, it is also supported and balanced to prevent the beam from overturning.

[0034] Working principle: The automatic transmission and intelligent early warning rotating bridge support device 6 is arranged along the circumferential direction of the slideway 17, the upper barrel ring plate 7 is arranged at the bottom of the upper turntable 2, the middle plate 8 is placed at the bottom plate of the upper turntable 2, the bottom of the lower barrel ring plate 9 is sealed with a steel plate, the upper barrel ring plate 7 and the lower barrel ring plate 9 are poured with C55 micro-expanding epoxy concrete 15, the lower barrel ring plate 9 is welded to the outer wall of the pressure sensor 11, every two automatic transmission and intelligent early warning rotating bridge support devices 6 are a group, each group of middle webs 14 are reinforced, each group of automatic transmission and intelligent early warning rotating bridge support devices 6 is provided with a slide plate 12 at the bottom, each group of pressure sensors 11 is connected to the wireless transmitter 16 of the switch by cable, and the data is projected and read on the mobile phone or each large display screen according to the code through the transmitter, and the data is set according to the early warning and alarm limit value, and the stress state is reflected by the size of the displayed value, and different representative colors and different audios are used for early warning / alarm prompts. When the limit value is reached, the system automatically transmits the information to the person in charge, and effective measures are taken in time. At the same time, during the pouring of the box beam, the construction of the prestressed beam, the unloading / dropping of the support system or the hanging basket, etc., the force fluctuations can be automatically transmitted and automatically warned, which can timely respond to the force state of the rotating bridge support device 6 with automatic transmission and intelligent warning, and effectively improve the risk prevention and control capabilities of the bridge rotation. Always carry out leveling while construction to ensure that the beam body is balanced at all times, thereby reducing the weighing test process of the rotating bridge body. The switch wireless transmitter 16 and the connecting cable are set on the inner side of the web 14 reinforcement plate, isolated from the construction surface, reducing the frequency of cable damage and ensuring the effective operation of the equipment.
