DETAILED DESCRIPTION

[0015] The utility model will be further described in the non-restrictive embodiment and in conjunction with the drawings:

[0016] ​​​​As shown in the drawings, a protection platform device of a bridge tower construction hydraulic climbing formwork device comprises telescopic platforms 1 arranged on each layer of construction platforms of the hydraulic climbing formwork device 5 and hydraulic oil cylinders 2. The hydraulic climbing formwork device 5 is prior art, and the hydraulic climbing formwork device 5 is provided with a top layer platform 5.1, a formwork construction platform 5.2, a hydraulic construction platform 5.3 and a bottom layer construction platform 5.4. The telescopic platform 1 is a rectangular platform structure, which can be formed by using a section steel as a framework and welding a steel plate on the upper part. The length of the telescopic platform 1 is basically the same as that of the construction platform, and the width of the telescopic platform 1 is greater than the gap between the construction platform and the concrete side. At least two hydraulic oil cylinders 2 are arranged on each layer of construction platforms in parallel. The hydraulic oil cylinders 2 are fixedly connected to the front part of the construction platform through their mounting seats, and the axis of the hydraulic oil cylinder 2 is perpendicular to the construction surface. The telescopic platform 1 is movably arranged above the hydraulic oil cylinder 2 in a horizontal direction. The front end of the telescopic platform 1 is connected with a front support frame 3 at the lower part. The front end of the telescopic platform 1 is connected with the oil cylinder rod of each hydraulic oil cylinder 2 through the front support frame 3. The front end of the telescopic platform is supported through the front support frame 3. The rear end of the telescopic platform 1 is provided with a rear support frame 4 at the lower part. The rear support frame 4 is a support leg structure. The upper end of the rear support frame 4 is fixedly connected with the rear end of the telescopic platform 1. The lower end of the rear support frame 4 is in sliding contact with the upper surface of the construction platform. The rear end of the telescopic platform 1 is slidingly supported on the construction platform through the rear support frame 4. The height of the rear support frame 4 should be greater than the height of the hydraulic oil cylinder 2, so as to prevent the telescopic platform from rubbing against the hydraulic oil cylinder 2 when the telescopic platform moves.

[0017] The hydraulic oil cylinders 2 arranged on each layer of construction platforms are controlled by a hydraulic system. The telescopic platform 1 is driven by the hydraulic oil cylinder 2 to automatically extend or retract through the hydraulic control system. The hydraulic control system is prior art.

The telescopic platform 1 is initially in a retracted state. After the hydraulic climbing formwork is positioned, the telescopic platform 1 is extended to the concrete side by controlling the hydraulic oil cylinder 2 through the control system. The gap between the construction platform and the concrete side can be sealed by the telescopic platform 1, so as to prevent personnel and objects from falling during construction. After the telescopic platforms of all the hydraulic climbing formwork devices arranged around the bridge tower are extended, the telescopic platforms of the same layer surround the outer contour of the concrete, which can effectively prevent personnel, objects and the like from falling and ensure construction safety. During normal pouring construction, the telescopic platform 1 is in an extended state, which can prevent personnel, objects and the like from falling. When the hydraulic climbing formwork device 5 climbs, the telescopic platform 1 is retracted, so as to ensure the climbing safety of the hydraulic climbing formwork device 5 and prevent the telescopic platform 1 from damaging the poured concrete.

[0019] In order to ensure the safety of the hydraulic climbing formwork device and prevent the telescopic platform from not being retracted when the hydraulic climbing formwork device climbs, a detection device and an alarm device (not shown in the drawing) for detecting whether the telescopic platform is retracted to the position are arranged on the construction platform of the hydraulic climbing formwork device, the detection device can adopt a photoelectric switch, when the photoelectric switch detects that the telescopic platform is not retracted to the position, the photoelectric switch can send a signal to the control device, and the alarm device can alarm, at this time, the hydraulic climbing formwork device cannot climb, and the safety of the hydraulic climbing formwork device can be improved.
