For solving the technical problem, the utility model discloses an automatically regulated safety passageway for open caisson includes the open caisson and locates the steel stair in the open caisson outside still include anchor assembly, guide rail, gyro wheel and passageway base, anchor assembly pre-buried in the open caisson top, the guide rail interval is laid in the half space of steel stair, the gyro wheel is located the guide rail slides and along the guide rail, passageway base front end articulate through the round pin axle in anchor assembly, passageway base rear end articulate through the round pin axle in the gyro wheel.

Furthermore, this escape way still includes anti-skidding decorative pattern steel sheet, anti-skidding decorative pattern steel sheet is laid in passageway base surface.

Furthermore, this escape way still includes the guardrail, the guardrail is located passageway base both sides, and the guardrail top surface is equipped with the hand protector.

Furthermore, this safe passageway still includes the connecting block, the connecting block is located the wheel carrier top surface of gyro wheel, passageway base rear end through the round pin axle articulate in the connecting block.

Furthermore, the channel base is made into a rectangular frame by adopting square tube welding, and reinforcing ribs are arranged in the rectangular frame at intervals along the longitudinal direction and the transverse direction.

Furthermore, the anchoring piece comprises a steel pipe vertically embedded at the top end of the open caisson and a connecting rod horizontally welded on the steel pipe, and the front end of the channel base is hinged to the connecting rod through a pin shaft.

Because the utility model discloses an automatically regulated escape way for open caisson has adopted above-mentioned technical scheme, this escape way includes the open caisson and locates the steel stair in the open caisson outside promptly, still includes anchor assembly, guide rail, gyro wheel and passageway base, and anchor assembly is pre-buried in the open caisson top, and the rest platform of steel stair is laid to the guide rail interval, and the guide rail is located to the gyro wheel and slides along the guide rail, and passageway base front end articulates in anchor assembly through the round pin axle, and passageway base rear end articulates in the gyro wheel through the round pin axle. This safe passageway overcomes the defect of frequent dismouting passageway in traditional open caisson construction, ensures the safe handling of passageway, and the material resources of using manpower sparingly improve the efficiency of construction of open caisson, saves open caisson construction cost.

Drawings

The invention will be described in further detail with reference to the following drawings and embodiments:

fig. 1 is a schematic elevation view of the automatically adjustable safety passage for an open caisson of the present invention;

fig. 2 is a schematic plan view of the safety channel.

Detailed Description

Embodiment is shown in fig. 1 and 2, the utility model discloses an automatically regulated safety passageway for open caisson includes open caisson 1 and locates the steel stair 2 in the open caisson 1 outside still includes anchor assembly 3, guide rail 4, gyro wheel 5 and passageway base 6, anchor assembly 3 pre-buried in 1 top of open caisson, guide rail 4 interval is laid in the half space of steel stair 2, gyro wheel 5 is located guide rail 4 slides along

guide rail

4, 6 front ends of passageway base articulate in anchor assembly 3 through

round pin axle

61, 6 rear ends of passageway base articulate in gyro wheel 5 through round pin axle 62.

Preferably, this safe passageway still includes anti-skidding decorative pattern steel sheet 63, anti-skidding decorative pattern steel sheet 63 lays in the passageway base 6 surface. The antiskid patterned steel plate is laid to improve safety and prevent surface slip.

Preferably, the safe channel further comprises guard rails 64, the guard rails 64 are arranged on two sides of the channel base 6, and hand guards 65 are arranged on the top surfaces of the guard rails 64. The guard bar and the hand guard are protection measures of the safety channel, and falling is avoided.

Preferably, the safety channel further comprises a connecting block 7, the connecting block 7 is arranged on the top surface of the wheel carrier of the roller 5, and the rear end of the channel base 6 is hinged to the connecting block 7 through a pin shaft 62. The connecting block is arranged to facilitate the connection between the channel base and the roller.

Preferably, the channel base 6 is a rectangular frame made of square tubes by welding, and reinforcing ribs are arranged in the rectangular frame at intervals along the longitudinal direction and the transverse direction. To improve the overall rigidity of the channel base

Preferably, the anchoring member 3 comprises a steel pipe 31 vertically pre-buried in the top end of the open caisson 1, and a connecting rod 32 horizontally welded to the steel pipe 31, and the front end of the channel base 6 is hinged to the connecting rod 32 through a pin 61.

During open caisson construction, the channel base drives the rear end of the channel base to slide along the rail through the roller by taking a hinge joint of the front end of the channel base and the anchoring piece as a fulcrum along with the sinking of the open caisson, so that the front end of the channel base sinks along with the open caisson, and the automatic adjustment of the safety channel for sinking along with the open caisson is realized.
