Detailed Implementation

[0021] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1-3 The retractable bridge railing construction device shown includes two construction units and a hinge device 15 that connects the two construction units. If needed, more construction units can be installed, with each pair connected by the hinge device 15, allowing for adjustable angles between the construction units. This device is suitable for constructing curved bridge railings. The hinge device 15 uses existing structures, such as hinges or latches.

[0023] Taking a construction unit as an example, the construction unit in this embodiment includes a construction frame 1, a counterweight frame 2, a sliding device, and a monitoring device 16.

[0024] The construction frame 1 includes a base plate 10, a telescopic assembly, a protective assembly, connecting rods, a limiting assembly, a triangular connecting frame, and a pressure sensor 11; wherein, the telescopic assembly includes a horizontal telescopic component 6 and a vertical telescopic component 5; the protective assembly includes a retaining rod 9 and a connecting rod 13.

[0025] The counterweight frame 2 includes a flat plate 7, a telescopic rod, and a diagonal brace 8.

[0026] In this embodiment, the horizontal telescopic member 6, the vertical telescopic member 5, and the telescopic rod can all adopt the same type of telescopic structure, for example, using... Figure 4 The telescopic structure shown includes an outer steel pipe 12, an inner steel pipe 14, and a locking pin. Multiple pin holes are spaced apart on the outer steel pipe 12 and the inner steel pipe 14. The inner steel pipe 14 is inserted into the outer steel pipe 12, and the locking pin is inserted into the aligned pin holes of the outer steel pipe 12 and the inner steel pipe 14, thus locking and limiting their movement. When the locking pin is removed, both can extend and retract. The telescopic structure includes a fixed section and a telescopic section that are relatively telescopically coordinated. The outer steel pipe 12 is the fixed section, and the inner steel pipe 14 is the telescopic section. The retaining rod 9 and the connecting rod 13 are connected to the fixed section of the telescopic structure. The telescopic section of the telescopic rod is hinged to the top of the diagonal brace 8, and the bottom of the diagonal brace 8 is hinged to the plate 7. The telescopic rod is vertically positioned, and the diagonal brace 8 is inclined. The telescopic rod and diagonal brace 8 of the counterweight frame 2 form a stable triangular structure with the plate 7. The plate 7 of the counterweight frame 2 is used to support the counterweight. Sliding devices are distributed at the four corners of the lower end of the plate 7.

[0027] The sliding device of the embodiment all adopts a pulley block. The sliding device greatly reduces the friction, and when the next area is constructed, the device can be manually pushed along the guardrail 4 to the next area.

[0028] The triangular connecting frame is welded and fixed at the top of the telescopic section of the vertical telescopic member 5, the fixed section of the vertical telescopic member 5 is connected with the fixed section of the horizontal telescopic member 6, and the telescopic section of the horizontal telescopic member 6 is connected with the bottom plate 10, so that the horizontal displacement and height adjustment of the bottom plate 10 are realized.

The surrounding rod 9 can be directly welded and fixed with the bottom plate 10, or can be welded and fixed with the horizontal telescopic member 6.

[0030] The connecting rod 13 is arranged above the surrounding rod 9 and is used as a crawling ladder of the construction frame 1, so as to facilitate the construction personnel to enter the bottom plate 10 in the construction frame 1 from the bridge.

[0031] The limiting assembly is clamped on both sides of the guardrail 4, and the limiting assembly comprises two clamping blocks, the clamping blocks are distributed on both sides of the guardrail 4, the clamping blocks are connected with the connecting rod member of the construction frame 1 and are suspended below the connecting rod member. The clamping blocks can keep a distance from the guardrail 4, so as to facilitate the adjustment of the angle of the construction frame 1.

[0032] The pressure sensor 11 prevents the construction frame 1 from being overloaded, so as to protect the safety of the construction personnel. The pressure sensor 11 is connected with an alarm, and the alarm is arranged at the top of the construction frame 1. When the bottom plate 10 is subjected to a pressure reaching a preset value, the alarm gives an audible and visual alarm.
