[0002] The trestle of the water bridge is used as a temporary working channel to facilitate the construction of the bridge. Generally speaking, the trestle is welded by multiple I-beams and large flat steel plates. The I-beams are located at the bottom of the large flat steel plates and supported by Bailey frames, while the large flat steel plates are used for people and vehicles to pass. Obviously, in order to avoid the deviation of the trestle, multiple I-beams need to be welded to the trestle. At present, the welding method is mainly to open a through hole in the large flat steel plate so that the welding gun can pass through the large flat steel plate downward and operate at the welding location. Although this method is conducive to workers working face down, the welding efficiency is low. Summary of the invention

[0034] Figure 1-Figure 9 A welding device for a trestle deck according to a preferred embodiment of the present invention is shown, comprising a support frame 1 and a welding tool 2.

[0035] See also Figure 1 and Figure 5 The support frame 1 includes a plurality of first horizontal I-beams 11 (see Figure 5 ), multiple second horizontal I-beams 12, multiple vertical I-beams 13, and vertical positioning plates 14. Multiple first horizontal I-beams 11 are arranged parallel to each other and at intervals, the second horizontal I-beams 12 are perpendicular to the first horizontal I-beams 11, and multiple second horizontal I-beams 12 are arranged parallel to each other and at intervals, and each second horizontal I-beam 12 is supported by multiple first horizontal I-beams 11. Multiple vertical I-beams 13 are divided into two groups of equal quantity, and the vertical I-beams 13 of the two groups are respectively arranged at both ends of the second horizontal I-beams 12, and the multiple vertical I-beams 13 belonging to the same group are arranged alternately with the multiple second horizontal I-beams 12 to form a supporting groove 15 between two adjacent vertical I-beams 13, and the supporting groove 15 is used to accommodate the third horizontal I-beam 3 of the trestle (see Figure 6 ). See Figure 1 , Figure 5 and Fig. 9 The vertical positioning plate 14 is fixedly connected to one end of all the second horizontal I-beams 12, and the horizontal height of the top of the vertical positioning plate 14 is higher than the horizontal height of the top of the vertical I-beam 13. Obviously, in this configuration, the support frame 1 is mainly assembled with I-beams to serve as a support pedestal for the trestle deck 4, and the parts are easy to obtain and the cost performance is high.

[0036] See also Figure 1The welding device includes two horizontal guide rails 21, a mobile tool 22, and a plurality of welding robots 23. The two horizontal guide rails 21 are respectively arranged on opposite sides of the support frame 1, and the extension direction of the horizontal guide rails 21 is consistent with the extension direction of the second horizontal I-beam 12. Figure 4 , the two ends of the movable tooling 22 are respectively connected to one of the horizontal guide rails 21 for sliding connection, see Figure 6 and Figure 8 , multiple welding robots 23 are installed on the mobile tooling 22, and each welding robot 23 is used to weld the position to be welded between one of the third horizontal I-beams 3 and the panel 4. In this way, by positioning the panel 4 and multiple third horizontal I-beams 3 at the same time, that is, positioning the workpiece, and then moving the welding robot 23 on the horizontal guide rail 21 to simultaneously complete the position to be welded between multiple third horizontal I-beams 3 and one of the panels 4, not only the welding efficiency is improved, but also the welding stripes are consistent and the welding quality is the same.

[0037] It should be noted that after the welded panel 4 and the third horizontal I-beam 3 are turned over, that is, when the panel 4 is located on the top of the third horizontal I-beam 3, the third horizontal I-beam 3 can be placed on the Bailey frame. In this way, the entire workpiece is prefabricated and then hoisted to the Bailey frame, thereby solving the problem of workers working face down and having low welding efficiency.

[0038] Obviously, by using I-beams as the main parts of the support frame 1, and by accommodating and positioning the workpieces through the supporting grooves 15 and the vertical positioning plates 14, the prerequisite for the mechanized welding of the workpieces by the welding robot 23 is provided. Therefore, the welding device for the trestle panel can complete the welding downward, and then turn the trestle panel 4 over and install it on the Bailey frame, thereby solving the problem of low welding efficiency.

[0039] Preferably, the plurality of vertical I-beams 13 are arranged in a staggered manner so that the top heights of two adjacent vertical I-beams 13 belonging to the same group are different. This arrangement facilitates workers to identify which supporting slot 15 the third horizontal I-beam 3 is specifically placed in, thereby improving the placement efficiency of the third horizontal I-beam 3.

[0040] Preferably, the welding gun 231 of the welding robot 23 is fixed on the mobile tooling 22. This arrangement can avoid the phenomenon of the welding gun 231 being offset. At this time, the welding gun 231 thus starts and stops to achieve the operation of the segmented welding stripes.

[0041] Preferably, welding guns 231 are provided on opposite sides of the movable tooling 22, and two welding guns 231 located on opposite sides of the movable tooling 22 jointly weld the same third horizontal I-beam 3. In this way, the welding efficiency can be greatly improved.

[0042] Preferably, in order to complete the mechanized welding work more automatically, the movable tooling 22 is provided with a motor and a roller connected to the motor drive, and the roller is supported by the horizontal guide rail 21 .

[0043] Preferably, in order to improve the stability of the movement of the movable tooling 22, the cross section of the horizontal guide rail 21 is an I-shaped structure.

[0044] The invention also discloses a welding method of a welding device for a trestle panel, including the welding device for the trestle panel, and further comprising the following steps: a placing step and a welding step.

[0045] Placing steps: first lay the panel 4 in the area between the two groups of vertical I-beams 13, and the panel 4 is located on the top of the second horizontal I-beam 12 and supported by the second horizontal I-beam 12, and then the side of the panel 4 is abutted against multiple vertical I-beams 13. Then, multiple third horizontal I-beams 3 of the trestle are placed on the top of the panel 4 and supported by the panel 4, and the two ends of each third horizontal I-beam 3 are respectively accommodated in two opposing supporting grooves 15; move the third horizontal I-beam 3 until it abuts against the vertical positioning plate 14.

[0046] Welding step: driving the movable tooling 22 to move from one end of the horizontal guide rail 21 to the other end, so that the multiple welding guns 231 synchronously complete the welding of the third horizontal I-beam 3 and the panel 4.

[0047] In this way, the welding of the third horizontal I-beam 3 and the panel 4 is completed in a mechanized manner, and then the third horizontal I-beam 3 and the panel 4 can be installed upside down, thereby solving the problem of difficulty in welding the panel 4.

[0048] In order to save welding points and improve welding efficiency, preferably, the welding gun 231 welds the points to be welded by interval welding, so that a plurality of welding lines are arranged at intervals along the length direction of the third horizontal I-beam 3 .

[0049] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
