[0002] Prefabricated assembly technology is mainly reflected in prefabrication, standardization, and factory production. Its characteristics are high-precision components, convenient and quick installation and construction, relatively less wet work on site, and less interference with the surrounding environment of the construction site. It is particularly suitable for emergency rescue projects, municipal engineering, and offshore bridges or rail projects.

[0003] The prefabricated and assembled construction of bridge engineering is a topic currently under research. At present, in the process of assembling and constructing prefabricated bridge cap beams, they are generally suspended to a suitable position by a sling mechanism, and then manually positioned and straightened.

In addition, it is difficult to self-lock the sling when the sling is lifting. During lifting, all the force is at the hook position, and the force cannot be shared at the hook position, resulting in stress concentration and poor lifting stability.

[0018] A method for using a prefabricated assembly mechanism for bridge cap construction comprises the following steps:

[0019] S1. When assembling the cap beam, first place the base plate on the cap beam so that the positioning ring is located in the bayonet. Then, the electric push rod is controlled to extend, and the electric push rod drives the movable frame to move upward, so that the movable frame squeezes the ball through the notch, and the ball drives the positioning column to move, so that the positioning column passes through the positioning ring and extends to the outer positioning hole, and the upward movement of the movable frame drives the tooth segment and the gear to drive, and the rotation of the gear drives the flip frame to flip downward, so that the flip frame remains upright;

[0020] S2, then hang the four ends of the lifting structure on four lifting rings respectively, and then the lifting structure lifts the cap beam upwards so that the cap beam is above the two bases;

[0021] S3. After hoisting, operate the electric hydraulic rod to drive the first slider on the top to move, and the first slider drives the first telescopic frame to unfold. After the telescopic frame is unfolded, the adjustment component drives the alignment component to extend downward to the base position. When the first slider below contacts the second slider in the frame, the first slider drives the second slider to move, and the second slider drives the second telescopic frame to unfold, so that the connecting frame drives the lateral movement, so that one of the pulleys contacts the opposite side of the two bases, and the two pulleys on the opposite side of the two bases are kept in contact with the bases, so that the cap beam is positioned left and right;

[0022] S4. When the two pulleys on the opposite sides of the two substrates contact the substrates and continue to apply force, one of the piston rods is retracted, and the liquid inside the sealing cylinder enters the other sealing cylinder through the delivery pipe. At this time, the other piston rod is pushed by the hydraulic pressure to push the pulley to contact the front and back sides of the substrate, so as to achieve the front and back alignment of the substrate;

[0023] S5. After alignment, keep the cap beam member aligned with the two bases, then lower the cap beam member so that the assembly holes can be smoothly docked with the steel bars, and then the cap beam member can be smoothly assembled with the base.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The prefabricated assembly mechanism and method for bridge cap beam construction are as follows: the cap beam alignment mechanism is assembled on the cap beam member, and the driving assembly and the flip assembly are transmitted, so that the flip assembly drives the alignment assembly to remain upright after flipping, so that the alignment with the base is completed, and the electric hydraulic rod controls the first telescopic frame to unfold, so that the alignment assembly is lowered to the base position, and when the first slider below slides to squeeze the second slider, the second telescopic frame is horizontally unfolded, so that the pulleys corresponding to the opposite sides of the two bases move to contact the base, and the left and right alignment of the cap beam member is maintained. At the same time, by continuously applying a force, the piston rod inputs the liquid inside the sealing cylinder into another sealing cylinder, so that the other piston rod is driven by the hydraulic pressure to drive the pulley to contact the front and back sides of the base, so that the cap beam member can be aligned front and back, so that the cap beam member and the base can be automatically aligned and straightened, and there is no need to climb to perform the alignment operation, which can greatly improve the operation safety and increase the installation speed;

[0026] 2. The prefabricated assembly mechanism and method for bridge cap beam construction, through the extension of the electric push rod, the electric push rod controls the movable frame to rise, the movable frame drives the tooth segment to move, the tooth segment and the gear are transmitted, the gear rotation can drive the flip frame to flip, so that the flip frame flips downward and remains upright, the bottom of the flip frame supports the bottom of the cap beam, so that when the lifting structure is lifted upward, the lifting force can be applied through the lifting ring, and the lifting force of the cap beam can also be shared by the flip frame, so that the cap beam can be kept stably lifted;

[0027] 3. The prefabricated assembly mechanism and method for the construction of the bridge cap beam drive the movable frame to move downward by retracting the electric push rod, so that the middle notch of the notch corresponds to the ball. At this time, the first spring drives the positioning column to retract and disengage from the positioning ring. At the same time, the movable frame moves downward, and also drives the tooth segment and the gear transmission, so that the gear drives the flip frame to flip upward, and then the flip frame is separated from the cap beam component. At this time, it is lifted upward by the lifting structure, so that the cap beam alignment mechanism can successfully complete the separation from the cap beam component, thereby automatically releasing the lock between the cap beam component, which is convenient for quick removal and prevents the subsequent high-altitude removal from causing operational inconvenience and greater safety hazards.

A gear 3021 is fixedly connected to the rotating shaft 3022. The gear 3021 is meshed with the tooth segment 3064. A flip frame 3024 is fixedly connected to one side of the gear 3021. The flip frame 3024 is L-shaped. After the flip frame 3024 is flipped and erected, its bottom contacts the bottom of the cover beam 100.

[0058] In this embodiment: the electric push rod 3061 retracts to drive the movable frame 3062 to move downward, so that the middle notch of the notch 3063 corresponds to the ball 3071. At this time, the first spring 3073 drives the positioning column 3072 to retract and disengage from the positioning ring 102. At the same time, the movable frame 3062 moves downward, and also drives the tooth segment 3064 and the gear 3021 to transmit, so that the gear 3021 drives the flip frame 3024 to flip upward, and then the flip frame 3024 is separated from the cap beam member 100.

[0059] A method for using a prefabricated assembly mechanism for bridge cap construction comprises the following steps:

[0060] S1. When assembling the cap beam 100, first place the base plate 301 on the cap beam 100 so that the positioning ring 102 is located in the bayonet 310. Then, the electric push rod 3061 is controlled to extend, and the electric push rod 3061 drives the movable frame 3062 to move upward, so that the movable frame 3062 squeezes the ball 3071 through the notch 3063. The ball 3071 drives the positioning column 3072 to move, so that the positioning column 3072 passes through the positioning ring 102 and extends to the outer positioning opening 305. The movable frame 3062 moves upward to drive the tooth segment 3064 and the gear 3021 to transmit. The gear 3021 rotates to drive the flip frame 3024 to flip downward, so that the flip frame 3024 remains upright.

[0061] S2, then hang the four ends of the hoisting structure 400 on the four hoisting rings 304 respectively, and then the hoisting structure 400 lifts the cap beam 100 upwards, so that the cap beam 100 is above the two bases 200;

[0062] S3. After hoisting, operate the electric hydraulic rod 3082 to drive the first slider 3083 above to move, and the first slider 3083 drives the first telescopic frame 3084 to unfold. After the telescopic frame is unfolded, the adjustment component 311 drives the alignment component 309 to extend downward to the position of the base 200. When the first slider 3083 below contacts the second slider 3112 in the frame 3081, the first slider 3083 drives the second slider 3112 to move, and the second slider 3112 drives the second telescopic frame 3111 to unfold, so that the connecting frame 3114 drives the lateral movement, so that one of the pulleys contacts the opposite side of the two bases 200, and the two pulleys on the opposite side of the two bases 200 are kept in contact with the base 200, so that the cap beam 100 is positioned left and right;

[0063] S4, when the two pulleys on the opposite sides of the two substrates 200 contact the substrate 200 and continue to apply force, one of the piston rods 3094 retracts, and the liquid inside the sealing cylinder 3091 enters the other sealing cylinder 3091 through the delivery pipe 3092. At this time, the other piston rod 3094 pushes the pulley to contact the front and back sides of the substrate 200 through hydraulic pressure, so as to achieve the front and back alignment of the substrate 200;

[0064] S5. After alignment, keep the cap beam 100 aligned with the two bases 200, then lower the cap beam 100 so that the assembly hole 101 can be smoothly docked with the steel bar 201, and then the cap beam 100 can be smoothly assembled with the base 200.
