Description

CROSS-REFERENCE TO RELATED APPLICATION

This patent application claims the benefit and priority of Chinese Patent Application No. 202211542590.1 filed with the China National Intellectual Property Administration on Dec. 2, 2022, the disclosure of which is incorporated by reference herein in its entirety as part of the present application.

TECHNICAL FIELD

The present disclosure relates to the field of buildings, and specifically to a removal-facilitated anchor sealing device for box girder construction.

BACKGROUND

A box girder is of a concrete structure, which is an important component of a bridge. In order to improve the construction efficiency of bridges, box girders are usually prefabricated first and then lifted onto piers for mounting. A box girder structure includes a bottom plate, a top surface, two side web plates, and wing plates. Prestressed tendons need to be laid in the two side web plates. Corrugated pipes are usually arranged before pouring. The corrugated pipes are fixed together with web plate bodies, and then steel strands are plugged into the corrugated pipes. Both ends of the steel strands are fixed with anchor plates. Prestressed tension is performed on the steel strands. After the tension is completed, the steel strands excessively extending out of two ends are cut off. Finally, a barrel-shaped mold is used to encircle the anchor plates and the steel strands. The mold is filled with concrete slurry. After the concrete is solidified, the mold is removed, and the anchor plates and the steel strands are wrapped and fixed by the columnar concrete. This action is referred to as anchor sealing.

In the prior art, anchor sealing is usually performed manually, and heights of anchor recesses are different, thereby resulting in high labor intensity. Moreover, an axis of each anchor recess is leveled with the ground, thereby making it difficult to fill slurry. After the concrete is solidified, it is also relatively difficult to remove the mold. Therefore, there is an urgent need for an anchor sealing device convenient for filling slurry and removing a mold.

As shown in FIG. 1 and FIG. 5, each of the anchor sealing units includes a first sliding chute 11 and a second sliding chute 12; the first sliding chute 11 and the second sliding chute 12 are both located on the top surface of the first box body 5 and are arranged in sequence from left to right; a lengthwise direction of the first sliding chute 11 and a lengthwise direction of the second sliding chute 12 are parallel to the first rotating shaft 7; the first rotating shaft 7 penetrates through the first sliding chute 11 and the second sliding chute 12 from left to right; and the first threaded section 8 is located in the first sliding chute 11, and the second threaded section 9 is located in the second sliding chute 12.

A first sliding block 13 is mounted in the first sliding chute 11; the first sliding block 13 sleeves on the first threaded section 8 and is in threaded connection with the first threaded section 8; a second sliding block 14 is mounted in the second sliding chute 12; the second sliding block 14 sleeves on the second threaded section 9 and is in threaded connection with the second threaded section 9; a top surface of the first sliding block 13 is provided with a second motor 15; an output shaft of the second motor 15 is fixedly connected with a first gear 16; a top surface of the second sliding block 14 is provided with a third motor 17; an output shaft of the third motor 17 is fixedly connected with a second gear 18; and a pipeline assembly is rotatably mounted between the first sliding block 13 and the second sliding block 14.

In this embodiment, when the first motor rotates, the first rotating shaft drives the first threaded sections and the second threaded sections to rotate, and the first threaded sections and the second threaded sections drive the first sliding block and the second sliding block to be separated and closed. The first sliding block and the second sliding block drive the pipeline assembly to be separated and closed. The second motor and the third motor drive the pipeline assembly to rotate.

As shown in FIG. 5 to FIG. 7, the pipeline assembly includes a first cylinder formed by combining a left half cylinder 19 with a right half cylinder 20; an axis of the first cylinder is parallel to the left and right side walls of the anchor sealing chamber 4; an outer circumferential wall of the left half cylinder 19 is fixedly connected with a second left half cylinder 21, and an outer circumferential wall of the right half cylinder 20 is fixedly connected with a second right half cylinder 22; the second left half cylinder 21 and the second right half cylinder 22 are combined into a second cylinder; the second cylinder communicates with the first cylinder, and an axis of the second cylinder is perpendicular to the first cylinder; a combined surface, which faces towards the right half cylinder 20, of the left half cylinder 19 is fixedly connected with a clamping block 23; a combined surface, which faces towards the left half cylinder 19, of the right half cylinder 20 is fixedly connected with a clamping slot 24; the clamping block 23 is matched with the clamping slot 24; the outer circumferential wall of the left half cylinder 19 is fixedly connected with a second rotating shaft 25; an axis of the second rotating shaft 25 is perpendicular to the left and right side walls of the anchor sealing chamber 4; the second rotating shaft 25 is rotatably mounted on the first sliding block 13 and is fixedly connected with a third gear 26; the third gear 26 is engaged with the first gear 16; the outer circumferential wall of the right half cylinder 20 is fixedly connected with a third rotating shaft 27; the third rotating shaft 27 is coaxial with the second rotating shaft 25; the third rotating shaft 27 is rotatably mounted on the second sliding block 14 and is fixedly connected with a fourth gear 28; and the fourth gear 28 is engaged with the second gear 18.

A ring slot 29 is formed in an outer circumferential wall of one end of the first cylinder; a combinable left half ring 30 and a combinable right half ring 31 are rotatably mounted in the ring slot 29; an end surface of one end of the left half ring 30 which is away from the first cylinder and an end surface of one end of the right half ring 31 which is away from the first cylinder are fixedly connected with several metal bosses 32; an end surface of one end of the left half ring 30 which is close to the first cylinder and an end surface of one end of the right half ring 31 which is close to the first cylinder are fixedly connected with a combinable left half tooth ring 33 and a combinable right half tooth ring 34 respectively; a fourth motor 35 is mounted on the outer circumferential wall of the left half cylinder 19; an output shaft of the fourth motor 35 is fixedly connected with a fifth gear 36; and the fifth gear 36 is engaged with the left half tooth ring 33 and the right half tooth ring 34.

In this embodiment, when anchor sealing is required, the second motor drives the left half cylinder to rotate through the third gear and the first gear, and the third motor drives the right half cylinder to rotate through the fourth gear and the second gear. The first cylinder rotates to the end with the left half ring and the right half ring and faces the front side and the anchor plates. In this case, the second cylinder faces down and will not work. The main box body slides forwards. The first cylinder gets close to the box girder to encircle most of the steel strands. A saw blade extends out to cut off excess steel strands. The steel strands fall into the first cylinder, drop out from a rear side of the first cylinder, and fall into a catching basket.

The main box body then continues to slide forwards until the metal bosses on the left half ring and the right half ring abut against end surfaces of the box girder. The fourth motor is started to drive the left half tooth ring and the right half tooth ring to rotate.

In this case, the second cylinder faces up and is located below the discharging end of the storage unit. The main box body slides forwards, and the first cylinder abuts against the box girder. The storage unit releases the slurry, and the slurry flows into the first cylinder via the second cylinder. The first telescopic rod extends out to drive the first disk to extend into the first cylinder. The first disk avoids the slurry from leaking out of the other side, and presses forwards and compacts the concrete, so that the concrete is formed into a concrete column. After the pouring of the concrete is completed, the left half cylinder and the right half cylinder are separated, and the first disk is withdrawn, so that the pipeline assembly is separated from the concrete column more easily. The combined surfaces of the left half ring and the right half ring are rotated to an angle that is consistent with an angle of the combined surfaces of the left half cylinder and the right half cylinder, which will not affect the opening of both the left half cylinder and the right half cylinder.

The first cylinder can be used for catching the steel strands, and the right half ring and left half ring on the first cylinder can perform roughening.
