[0041] The device is used, first of all, through the lifting tool and the lifting rope is fixed on the two top plates 5 and the two bottom plates 1, that is, the state of the supporting unit 4 can be changed through the lifting rope, initially, the supporting unit 4 is in the unlocked state, the hinge structure is arranged in the supporting unit 4, the straight plates 1301 of the supporting modules 13 are matched with each other, and are connected to form an "X-shaped" structure, the opening state of the device can be changed through the lifting rope, after the pier column 8 is constructed, the device is installed on the top or side of the upper side of the pier column 8 through the lifting tool and the lifting rope, then the workers tighten the self-locking hoop again to ensure that the device is firmly installed on the pier column 8.

[0042] The top plate 5 is used as the construction platform of the top, the bottom plate 1 is used as the temporary standing base of the workers, in addition, vertical rods are installed on the bottom plate 1 near the edge, the vertical rods and the bottom plate 1 are detachably designed, the protective nets are installed between the adjacent vertical rods, and the safety of the construction workers is further ensured.

[0043] In the preferred scheme, the half-ring clamping plate 3 is connected through the follow-up unit 9 and the limiting plate 2, one side of the follow-up unit 9 is electrically connected with the mobile power supply 11, one side of the follow-up unit 9 is provided with the locking unit 10, the locking units 10 on the two bottom plates 1 are connected through the pull rope 20;

[0044] The locking unit 10 comprises the meshed worm 1001, the worm wheel 1003 and the uniform line roller 1027, the lower side of the worm wheel 1003 is provided with the lock sleeve 1004, the uniform line roller 1027 is fixed on the opposite bottom plate 1, one side of the lock sleeve 1004 is provided with the locking rod 1010, the two sides of the pull rope 20 are respectively fixed on the lock sleeve 1004 and the locking rod 1010, the pull rope 20 is wound on the uniform line roller 1027, and the length adjustment of the pull rope 20 is completed by rotating the lock sleeve 1004.

[0045] The preferred mobile power supply 11 adopts a portable outdoor power supply, which can ensure the stability of power supply, and does not need to be externally connected to the power box on land through a cable, for water operation, greatly reduces the safety risk of power use, avoids the trouble of cable installation, and effectively controls the risk points.

[0046] In the process of construction of the pier column 8, it is difficult to ensure that the upper and lower parts are coaxial and the outer wall profile is projected to the lower end in an absolutely consistent state. In actual construction, there is a certain fluctuation within the allowable range. After positioning by the follow-up unit 9, the above problems can be overcome. The bottom plate 1 and the half-ring clamping plate 3 can be adjusted within a certain angle range, that is, the half-ring clamping plate 3 is fully attached to the pier column 8, and the two side bottom plates 1 can have a certain horizontal fluctuation. Then the locking unit 10 tightly pulls and fixes the two opposite bottom plates 1 by the pull rope, until the half-ring clamping plate 3 is stably fixed on the pier column 8 by the friction force. Since the worm 1001 and the worm gear 1003 have self-locking ability, that is, when the length of the pull rope 20 is adjusted by the worm 1001 and the worm gear 1003, the two bottom plates 1 are pulled together under the action of their own gravity during installation. In order to improve the degree of automation of the whole, a servo motor (which can bear the torque required for use) is preferably installed on one side of the worm 1001 to transmit torque to the worm 1001. If necessary, a reducer is connected between the servo motor and the worm 1001. At this time, the overall self-locking safety is higher. When the device is hoisted onto the pier column 8, part of the position of the half-ring clamping plate 3 contacts the pier column 8 under the action of gravity. At this time, the servo motor is manually controlled to work, so that the two bottom plates 1 are adjusted to the design position by the pull rope 20. Then the person approaches the device by the basket and fixes it again. After the fixing is completed, even if the servo motor is in an inactive state, the whole device has a certain safety guarantee.

[0048] The motor 902 can drive the driving sleeve 903 to rotate, so that when the upper locking plate 7 gradually approaches the pier column 8, the motor 902 can drive the support unit 4 and the bottom plate 1 to approach, thereby changing the position thereof. Since the half-ring clamping plate 3 is attached to the pier column 8, an inclination angle can be formed between the bottom plate 1 and the half-ring clamping plate 3, so that the locking plate 7 and the half-ring clamping plate 3 of different heights can be installed on the pier column 8.
