DETAILED DESCRIPTION

[0022] The utility model will be further explained in connection with the drawings and examples, and the mode of the utility model includes but is not limited to the following examples.

[0023] The steel structure movable threshold protective airtight door frame is mainly made of steel plates cut to specific sizes as raw materials and welded together by welders. During welding, the welder usually operates on the ground, or two wooden blocks are placed parallel to each other on the ground to support the welding raw materials. The inventor found that although this method does not affect the welding process, the self-weight of the welded door frame is relatively large, and it is difficult to find slings or hooks to apply force during hoisting, making it inconvenient to transport. If there is a welding platform for the door frame that can be easily lifted by a lifting device after the door frame is welded, it will greatly facilitate the transportation of the door frame and help shorten the overall production time of the protective door.

[0024] First embodiment:

[0025] like Figures 1-2 As shown, the steel structure movable threshold protective airtight door frame processing device provided by this utility model includes: a processing bed 10, the overall shape of which is as follows: Figure 1 As shown, specifically, the processing bed 10 includes a rectangular frame 11 for supporting the raw materials used to make the door frame. Four support legs 12 are welded to the lower end of the frame 11 to support its weight. The lower ends of the support legs 12 contact the ground. The upper end of the processing bed 10 has bolt through holes, and corresponding bolt through holes are also provided on the sleepers 20 of the same specifications. A tie bolt is installed in both bolt through holes to fix the relative position of the sleepers 20 and the processing bed 10. On the other hand, as... Figure 2 As shown, the sleeper 20 includes end sleepers 21 symmetrically arranged at both ends of the processing bed 10 and an intermediate sleeper 22 located between the two end sleepers 21. The area between the adjacent ends of the end sleepers 21 and the intermediate sleeper 22 is a reserved gap 23, as shown. Figure 1 As shown, the reserved slot 23 is used for the forklift boom's front fork to enter. During operation, the cut steel plate materials are first placed on the end rest 21 and the middle rest 22. Then, the welder welds and fixes the steel plates together to form a rectangular door frame. Finally, the forklift boom's front fork is inserted into the reserved slot 23 on both sides of the processing bed 10. At this time, the forklift boom's front fork is located at the lower end of the rectangular door frame. After the forklift's lifting system is started and the front fork is slowly moved upward, the rectangular door frame is lifted by the front fork. Similarly, this device is also suitable for cranes to lift the door frame. First, a sling is passed through the reserved slot 23 on both sides of the processing bed 10. Then, the two ends of the sling are hung on the crane hook. Finally, the crane is started so that the sling applies an upward pulling force to the door frame. The door frame is then lifted and moved to another manufacturing site.

[0026] By setting a reserved gap 23, it is convenient for one of the devices to lift and transfer the door frame located on the processing bed 10.

[0027] Second embodiment:

[0028] like Figure 1As shown, the edge of the end pillow 21 has a protrusion 211, which is a thin edge along the outer edge of the end pillow 21, which has two functions, one is to limit the steel plate used to make the door frame to the horizontal plane it surrounds, and the other is to provide a standard line to help the workers align the ends of the steel plate on both sides of the door frame.

[0029] Third embodiment:

[0030] As shown in the Figures 2-3 As shown in the, the processing bed 10 is also provided with an alignment piece 30 for aligning the welding raw materials of the door frame, specifically, the alignment piece 30 includes a stop bar 36 located at the upper end of the frame 11 and a drive assembly for sliding the stop bar 36 on the upper end of the frame 11, the drive assembly includes a motor 31 installed on one side of the frame 11, a support 35 is installed at the front end of the rotating shaft of the motor 31 at the lower end of the frame 11, a screw rod 32 is rotatably installed on the support 35, the other end of the screw rod 32 is also installed with a support 35, which is fixed on the lower end of the frame 11 through a lock bolt, the screw rod 32 passes through the threaded hole on the sliding block 33 which is matched with it, on the other hand, a sliding rod 34 is arranged in the same plane as the screw rod 32 and parallel to it at the lower end of the frame 11, the two ends of the sliding rod 34 are fixed on the frame 11 using supports 35, the sliding block 33 is slidably installed on the sliding rod 34, and the sliding block 33 on the sliding rod 34 and the sliding block 33 on the screw rod 32 are jointly welded with an arc-shaped connecting frame 351, the upper end of the connecting frame 351 is welded and fixed with the stop bar 36, the motor 31 and the parts connected thereto such as the screw rod 32 constitute a screw rod mechanism, that is, when the motor 31 rotates, it drives the screw rod 32 to rotate, the screw rod 32 pushes the sliding block 33 on it to move, thereby driving the sliding rod 34 on it to slide along the upper end of the end pillow 21.

[0031] By setting the sliding rod 34, the steel plate placed on the end pillow 21 can be clamped between the protrusions 211 on the upper ends of the two end pillows 21 to fix its position, preventing the steel plate from being inadvertently pushed during welding, resulting in welding errors.

[0032] Fourth embodiment:

[0033] As shown in the Figure 2 The lower end of the support leg 12 is provided with a foot pad 13, which is a circular rubber pad, and a screw rod is fixed on it using glue, the lower end of the support leg 12 is provided with a threaded hole matched with the screw rod, and the foot pad 13 is threadedly connected with the support leg 12.

[0034] By setting the screw rod in threaded connection with the support leg 12, the length of the screw rod entering the threaded hole of the support leg 12 can be adjusted, thereby changing the length of the threaded rod exposed outside the threaded hole, and further changing the height of the lower end of the support leg 12 from the ground, and the lower end of each of the four support legs 12 is provided with an adjustable foot pad 13, so that the device can be stably supported and kept horizontal on uneven ground.

[0035] Working principle: the forklift's lifting arm front fork is inserted into the reserved slot 23 on both sides of the processing bed 10, at this time, the lifting arm front fork is located at the lower end of the rectangular door frame, after the forklift's lifting system is started to control the front fork to slowly move up, the rectangular door frame is lifted up by the front fork.

[0036] The above embodiment is only one of the preferred embodiments of the present application, and should not be used to limit the protection scope of the present application, but any insignificant modification or polishing made in the main design idea and spirit of the present application, the technical problems solved are still consistent with the present application, and should be included in the protection scope of the present application.
