Detailed Implementation

[0021] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0022] An innovative feature of a simple, movable box girder assembly device is that it includes a gantry moving unit, a conveying unit 1, an assembly unit, and a welding unit 9. The gantry moving unit includes a slide rail 2 and a gantry assembly 17 that is slidably mounted on the slide rail. A conveying unit is provided between the two slide rails, and the assembly unit and welding unit are installed on the gantry assembly.

[0023] The gantry assembly is mainly welded from square tubing, offering advantages such as high strength and light weight. It includes a first gantry 8, a second gantry 6, an installation platform 7, and connecting beams. The first and second gantry frames are arranged opposite each other. An installation platform is horizontally welded between the first and second gantry frames, near the top. A welding unit is installed on this installation platform. Connecting beams are horizontally welded to the legs of the first and second gantry frames below the installation platform. The assembly unit is installed on the first gantry frame. Lockable rollers are installed at the bottom of the four legs of the gantry assembly for moving and fixing the assembly, ensuring the assembly of box girders of different lengths (a movable gantry assembly is used to fully utilize the box girder production line).

[0024] The conveying unit includes a frame 3, conveying rollers 19 and a conveying geared motor. Conveying rollers are arranged at intervals on the frame, and sprockets are installed at the ends of each conveying roller. A chain is wound around each sprocket. The conveying rollers located at the ends of the frame are driven by the chain of the conveying geared motor.

[0025] The assembly unit includes a side assembly mechanism and a top assembly mechanism. The side assembly mechanism has two driving methods: one side is controlled by an electric lead screw, and the other side is controlled by a hydraulic cylinder. Because hydraulic pressure can leak, one side uses an electric lead screw, while the clamping is controlled by hydraulic pressure. Specifically, the side assembly mechanism includes a mounting plate 14, a side hydraulic cylinder 16, a side electric lead screw 15, and a side clamping wheel 13. Mounting plates are welded on both sides between the first gantry and the second gantry. A side clamping wheel driven by the side hydraulic cylinder is installed on one mounting plate, and a side clamping wheel driven by the side electric lead screw is installed on the other mounting plate.

[0026] The top assembly mechanism includes a top hydraulic cylinder 10, a lifting beam 11, side slide rails, and top pressure rollers 12. A top hydraulic cylinder is installed on the top of the first gantry frame, and a lifting beam is installed on the cylinder rod of the top hydraulic cylinder. The two ends of the lifting beam slide on the side slide rails provided on the legs of the first gantry frame. Two top pressure rollers are installed at intervals at the bottom of the lifting beam.

[0027] The bottom side of the lifting beam is a plate with several evenly spaced mounting holes. The top pressure roller is connected to the lifting beam through the holes and screws at the four corners of the wheel seat. In use, the position of the top pressure roller can be adjusted according to the width of the box girder to be assembled.

[0028] The welding unit is a carbon dioxide shielded welding machine, which performs electric welding during assembly.

[0029] Working principle:

[0030] During the alignment process, the assembly equipment uses the extension of the hydraulic cylinder rod and the rotation of the electric lead screw to clamp and press the web plate 4 of the box girder 18, so that it meets the dimensions of the box girder. The conveying unit drives the box girder forward, and fixed welding is performed while it is moving forward to complete the assembly and splicing.

[0031] Work process:

[0032] 1. Determine the position of the gantry assembly based on the length of the box girder to be assembled, and lock the rollers and slide rails on the gantry assembly to prevent the gantry assembly from moving;

[0033] 2. Place the base plate on the conveyor rollers and install the middle partition plate 5 of the box beam;

[0034] 3. Next, install the web plates on both sides of the box girder, control the conveyor rollers to drive the box girder forward, and control the hydraulic cylinder and electric screw to accurately clamp and compact the profile to prevent positional deviation during the assembly process and ensure the assembly dimensions of the box girder;

[0035] 4. Use MIG welding to fix the box girder with spot welding, connect the various components of the box girder together, and complete the assembly of the box girder.

[0036] Although embodiments and drawings of the present invention have been disclosed for illustrative purposes, those skilled in the art will understand that various substitutions, variations and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
