Figure 4 Schematic diagram of the lengthening operation of the lengthening device of the shore container crane beam according to the embodiment of the present invention Figure 1 The technical solution of this embodiment is basically the same as that of the second embodiment, except that the embodiment further includes the step of arranging the process support 5 along the first direction A on both sides of the cutting line L before cutting the beam along the cutting line L to form the beam rear section 11 and the beam front section 12. This can prevent the beam bodies at both ends, i.e., the beam front section 12 and the beam rear section 11, from shrinking or expanding after the beam is cut.

[0095] The technical solution of this embodiment is basically the same as that of the second embodiment, and the only difference is that the embodiment further includes a step of moving the front section 12 of the beam in the second direction B and fixing it, including: setting a pull ear and a wire rope in the second direction B, which are used to move the front section 12 of the beam arranged on the second bracket trolley 32.

[0098] Figure 6 Schematic diagram of the lengthening operation of the lengthening device of the shore container crane beam according to the embodiment of the present invention Figure 3 The technical solution of this embodiment is basically the same as that of the second embodiment, except that the embodiment further includes the step of moving the beam extension section 41 between the beam rear section 11 and the beam front section 12 and aligning them with each other, including: moving the beam extension section 41 disposed on the first bracket trolley 31 along the first direction A to between the beam rear section 11 and the beam front section 12; moving the beam extension section 41 along the third direction C and aligning them with the beam rear section 11 along the second direction B. Specifically, before moving the beam extension section 41, ensure that the beam extension section 41 is slightly shorter than the beam rear section, and then adjust the height of the beam extension section 41 in the third direction C by using the jack 6 and sleepers placed on the first bracket trolley 31. The beam extension section 41 is based on the beam rear section 11 and is first docked with the beam rear section 11. Because the beam rear section 11 is more stable as a whole, the accuracy after docking is higher. Subsequently, it is necessary to fine-tune the beam front section 12. After the beam extension section 41 is moved into place along the first direction, the height of the beam extension section 41 in the third direction C is adjusted by using the jack 6.

Specifically, the first bracket trolley 31, the second bracket trolley 32, the process support 5, and the extended beam section 41 are hoisted onto the vehicle frame 22 using a truck crane and fixed to prevent the elongated trolley tooling from sliding off after being moved.

[0101] The technical solution of this embodiment is basically the same as that of the second embodiment, except that the embodiment further includes, after the step of moving the extension trolley fixture 2 to below the front section 12 of the beam, the step of: releasing the connection between the bridge crane trolley and the extension trolley fixture 2. Specifically, the connecting rod between the bridge crane trolley and the extension trolley fixture is released, the bridge crane trolley moves to the parking position, stops and anchors, and then the trolley traction wire rope is removed.

[0102] The technical solution of this embodiment is basically the same as that of the second embodiment, except that the embodiment further includes the step of controlling the butt joint flatness and the shrinkage of the joint seam welding of the port before connecting the beam extension section 41 with the beam rear section 11 and the beam front section 12. Specifically, before connecting the beam extension section 41 with the beam rear section 11 and the beam front section 12, the connection may be welding, and a card code is used to fix the port splicing position to control the butt joint flatness and the shrinkage of the joint weld. After the staff confirms that the docking size is correct, spot welding is carried out to complete the docking of the extended section of the beam and the rear section of the beam; then the docking of the front section of the beam and the extended section of the beam is completed according to the above steps. After all the spot welding work is completed, welding is started; after welding is completed, the weld quality is checked, as well as subsequent work such as grinding and painting; the tooling parts are removed, and the connection of the wire rope and accessories is restored; the functions required for the lengthening operation are restored or extended, mainly referring to the displacement of the deceleration limit and parking limit on the beam, and the lengthening of the anti-collision system.
