[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 3This utility model provides an adjustable trapezoidal cable tray welding fixture, including a support platform 1, a placement platform 5 connected to the top of the support platform 1, and two L-shaped side plates 4. The placement platform 5 is provided with multiple placement slots 15 for placing crossbars 7, and the number of placement slots 15 is reasonably set according to the size of the trapezoidal cable tray. The placement slots 15 are connected to pressure plates 6 for positioning the crossbars 7, and the length of the pressure plates 6 is equal to the width of the placement platform 5. The pressure plates 6 are connected to a drive mechanism for driving the multiple pressure plates 6 to reciprocate. The drive mechanism includes a moving rod 13, a moving block 11, and two push-pull plates 10. The moving rod 13 is connected to the multiple pressure plates 6, and the end of the moving rod 13 is connected to the moving block 11. The moving block 11 is movably connected to the support platform 1. The two ends of the push-pull plates 10 are connected to the L-shaped side plates 4 and the moving block 11, and the push-pull plates 10 are connected to cylinders 3 for driving the push-pull plates 10 to move.

[0020] The spacing between adjacent placement slots 15 is equal. When the horizontal bar 7 is in the positioning state, the spacing between adjacent horizontal bars 7 is equal, so that the horizontal bar 7 is in a suitable position, which facilitates subsequent welding operations.

[0021] During installation of side plate 8, multiple heat dissipation holes 9 are provided on side plate 8. Bolts are used to pass through the heat dissipation holes 9 to facilitate the limiting and fixing of side plate 8, so that side plate 8 is tightly attached to the inner side of L-shaped side plate 4, improving the stability of the connection between the two. Multiple crossbars 7 are placed in their respective placement slots 15, and the placement position is not strictly required. Cylinder 3 drives L-shaped side plate 4 to move forward, so that the two side plates 8 are close to each other. L-shaped side plate 4 applies a pushing force to push-pull plate 10, which drives moving block 11 to move forward. Moving block 11 pulls moving rod 13 to move, so that multiple pressure plates 6 move forward synchronously. Until moving block 11 moves to the appropriate position, pressure plate 6 presses against crossbar 7, and the two ends of crossbar 7 are connected to side plate 8, which provides good limiting for crossbar 7 and facilitates subsequent welding operations between crossbar 7 and side plate 8.

[0022] The bottom inner side of side 8 is surface a, and the bottom surface of the placement groove 15 is aligned with surface a, that is, the bottom of the horizontal bar 7 is aligned with surface a, making it convenient for the horizontal bar 7 to be placed on surface a.

[0023] A sliding groove 17 is provided in the placement groove 15. A sliding block 16 is slidably connected to the sliding groove 17. The sliding block 16 is fixedly connected to the pressure plate 6. The sliding block 16 slides in the sliding groove 17, which guides the pressure plate 6 and improves the stability of the movement of the pressure plate 6.

[0024] The movable rod 13 is fixedly connected to a plurality of sliding blocks 16, and the movable rod 13 is slidably connected to the placement platform 5.

[0025] The drive mechanism also includes a connecting cylinder 18 and a spring 19. The connecting cylinder 18 is fixedly connected to the moving block 11, and the moving rod 13 is inserted into the connecting cylinder 18. The two ends of the spring 19 are connected to the moving rod 13 and the connecting cylinder 18. When the pressure plate 6 is connected to the crossbar 7, the two ends of the crossbar 7 are not against the inner side of the side 8. The moving block 11 continues to move forward, and the moving rod 13 slides relative to the connecting cylinder 18. The spring 19 is gradually stretched, so that the pressure applied by the pressure plate 6 to the crossbar 7 gradually increases until the two ends of the crossbar 7 are connected to the inner side of the side 8. At this time, the moving block 11 stops moving. At this time, the relative position of the crossbar 7 and the side 8 is appropriate, and the crossbar 7 is in a positioning and locking state, which improves the stability of the connection between the crossbar 7 and the side 8 and facilitates subsequent welding operations.

[0026] The top of the support platform 1 is provided with a guide groove 12, and the moving block 11 is slidably connected to the guide groove 12 to improve the stability of the movement of the moving block 11.

[0027] The two ends of the push-pull plate 10 are connected to the L-shaped side plate 4 and the moving block 11 via shafts.

[0028] The top of the support platform 1 is connected to four cylinder seats 2. The cylinder 3 is connected to the cylinder seat 2, and the power output end of the cylinder 3 is connected to the L-shaped side plate 4. The L-shaped side plate 4 is slidably connected to the top of the support platform 1.

[0029] The L-shaped side plate 4 is connected to the side edge 8 by multiple bolts. Tools are used to operate the multiple bolts to facilitate the installation of the side edge 8.

[0030] Working principle: Side 8 is placed inside L-shaped side plate 4, and bolts are used to lock and fix side 8 through heat dissipation holes 9, improving the stability of the connection between side 8 and L-shaped side plate 4. Then, multiple crossbars 7 are placed in the corresponding placement slots 15. Cylinder 3 pushes L-shaped side plate 4 forward, bringing two side 8 closer together. L-shaped side plate 4 applies a pushing force to push-pull plate 10, which pushes moving block 11 forward. Moving block 11 simultaneously drives moving rod 13 forward, realizing the forward movement of multiple pressure plates 6. When pressure plate 6 is just connected to crossbar 7, the two ends of crossbar 7 are not in contact with the inner surface of side 8. Moving block 11 continues to move forward, moving rod 13 slides relative to connecting cylinder 18, spring 19 is gradually stretched, and the tension applied to moving rod 13 gradually increases, that is, pressure plate 6 gradually presses against crossbar 7. The moving block 11 stops moving when both ends of the crossbar 7 are connected to the inner side of the side 8. At this time, the crossbar 7 is in a locked position, which facilitates the welding operation between the crossbar 7 and the side 8. After welding is completed, the bolts on the heat dissipation hole 9 are removed with a tool, so that the side 8 and the L-shaped side plate 4 are in a loosened state. The cylinder 3 drives the L-shaped side plate 4 to move backward, and the L-shaped side plate 4 separates from the side 8. The L-shaped side plate 4 applies a pulling force to the push-pull plate 10, so that the moving block 11 moves back. That is, the moving block 11 pushes the moving rod 13 back to its original position, so that the pressure plate 6 separates from the crossbar 7, thereby loosening the trapezoidal cable tray and facilitating the unloading operation.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
