[0036] Working principle:

[0037] When it is necessary to transport the adjustable gauge pull rod, the operator pulls out the sealing plug 18 by hand, and then rotates the hand wheel 16 through the T-shaped slot 17. The hand wheel 16 can drive the two-way wire lever 3 to rotate. Since the two-way wire lever 3 and the two sets of screw sleeves 4 threads cooperate with each other, the rotating two-way wire lever 3 can push the two sets of screw sleeves 4 to move towards each other. The two sets of screw sleeves 4 respectively drive the two sets of sealing covers 10 to move towards each other through the two sets of socket plates 5 and the two sets of insulating rods 6. When the two sets of sealing covers 10 are respectively inserted into the openings at both ends of the storage square tube 1, the sealing plug 18 is reset. At this time, multiple storage square tubes 1 can be stacked and stored, which is convenient for later transportation. When it is necessary to use the adjustable gauge pull rod, Pull out the sealing plug 18 again, and then rotate the handwheel 16 in the opposite direction. The handwheel 16 rotating in the opposite direction can drive the two-way wire lever 3 to rotate, and the two-way wire lever 3 rotating in the opposite direction can push the two sets of screw sleeves 4 to move away from each other. The two sets of screw sleeves respectively drive the two sets of sealing covers 10 to move away from each other through the two sets of socket plates 5 and the two sets of insulating rods 6. When the two sets of sealing covers 10 are moved to the appropriate positions, the two sets of first slot plates 12 and the two sets of second slot plates 13 can be moved to the side of the track, and then the four sets of fastening bolts 14 are rotated clockwise, and then the four sets of mounting bolts 15 are rotated clockwise. When the four sets of mounting bolts 15 are in contact with the track, the installation work is completed, and the cross bar 19 can ensure the stability of the lateral movement of the two sets of socket plates 5. Qualitatively, the partition plate 2 and the sealing cover 10 are arranged, and the use position of the clamping device can be stored and adjusted, thereby improving the safety of the transportation of the adjustable-distance railway gauge pull rod. At the same time, when the adjustable-distance railway gauge pull rod needs to be moved and used, the operator moves the four sets of lifting plates 8 by hand, and the four sets of lifting plates 8 respectively drive the four sets of universal wheels 9 to move synchronously. When the four sets of universal wheels 9 are respectively moved out of the interior of the four sets of mounting shells 7, the eight sets of positioning screws 20 and the sixteen sets of positioning nuts 21 are used to cooperate with each other, and the operator rotates the sixteen sets of positioning nuts 21 clockwise and counterclockwise by hand. When the sixteen sets of positioning nuts 21 are respectively in close contact with the four sets of lifting plates 8, the use position of the four sets of lifting plates 8 is adjusted. The storage square tube 1 is fixed. At this time, the storage square tube 1 can be lifted and the four sets of universal wheels 9 can be placed on the ground. At this time, the four sets of universal wheels 9 can be used to move the storage square tube 1. When the storage square tube 1 is moved to a suitable position, the sixteen sets of positioning nuts 21 are rotated in the opposite direction. Then, the four sets of universal wheels 9 can be moved into the interior of the four sets of mounting shells 7 respectively through the four sets of lifting plates 8. Then, the sixteen sets of positioning nuts 21 are rotated again. When the sixteen sets of positioning nuts 21 are in close contact with the four sets of lifting plates 8 again, the four sets of universal wheels 9 are fixed in the interior of the four sets of mounting shells 7 respectively. By setting the mounting shell 7, lifting plate 8 and universal wheels 9, the gauge rod can be moved and used labor-savingly and conveniently, which brings convenience to the transportation of the adjustable gauge rod of the railway.
