[0020] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1 As shown, a typical embodiment of the present invention provides an adjustable interval maintenance platform, including a platform pedal 1, a transverse support 2, a longitudinal support 3, an oblique support 4 and a strip hole 5. The longitudinal support 3 is used to be fixed on the shield section. A transverse support 2 is fixedly installed on both sides of the bottom of the platform pedal 1. The top end of the longitudinal support 3 is rotatably connected to one end of the transverse support 2, and the bottom end of the oblique support 4 is rotatably connected to the bottom end of the longitudinal support 3. The strip hole 5 is opened on the side of the transverse support 2 away from the top end of the longitudinal support 3. A fastener is movably installed in the strip hole 5, and the top end of the oblique support 4 is rotatably connected to the fastener.

[0022] The transverse supports 2, longitudinal supports 3, and diagonal supports 4 are all angle steel. When applying this embodiment, the longitudinal supports 3 are fixed to the shield section. Then, the transverse supports 2 and diagonal supports 4 swing on the longitudinal supports 3 to adjust the inclination angle of the platform pedal 1, ultimately making the platform pedal 1 parallel to the ground.

[0023] At least two expansion bolts 6 are provided on the longitudinal support 3 for fixing the longitudinal support 3 on the shield section.

[0024] The transverse support 2 and the longitudinal support 3, as well as the longitudinal support 3 and the diagonal support 4, are connected by first bolts 7 and first nuts 8. When adjusting the platform pedal 1, the first nuts 8 and first bolts 7 are rotated to make the transverse support 2 and the longitudinal support 3, and the diagonal support 4 and the longitudinal support 3 relatively loose. After the platform pedal 1 is adjusted, the first bolts 7 and first nuts 8 are rotated to tighten the transverse support 2 and the longitudinal support 3, and the diagonal support 4 and the longitudinal support 3, to improve the stability of the platform pedal 1.

[0025] The fastener includes a second bolt 9 and a second nut 10 . The second bolt 9 passes through the strip hole 5 and the longitudinal support 3 and is connected to the second nut 10 .

[0026] Use the second bolt 9 to connect the top of the diagonal support 4 with the transverse support 2. At the same time, during the adjustment of the platform pedal 1, the second bolt 9 is displaced in the strip hole 5. After the adjustment of the platform pedal 1 is completed, the second bolt 9 and the second nut 10 are tightened to fasten the transverse support 2 and the diagonal support 4. In this way, the diagonal support 4 cooperates with the longitudinal support 3 to support the platform pedal 1, further improving the stability of the platform pedal 1.

[0027] like Figure 2 and Figure 3 As shown, in a typical embodiment 2 of the present invention, the outer top of the longitudinal support 3 is fitted with the inner side of the transverse support 2, and the outer bottom of the oblique support 4 is fitted with the inner bottom of the longitudinal support 3. The fastener also includes a pad 11 arranged on the inner side of the transverse support 2, and the top of the outer side of the oblique support 4 is fitted with the inner side of the pad 11. A through groove 12 adapted to the strip hole 5 is provided on the pad 11, and the second bolt 9 passes through the through groove 12.

[0028] The backing plate 11 blocks the gap between the transverse support 2 and the oblique support 4 so that after tightening the second bolt 9 and the second nut 10 , the transverse support 2 and the oblique support 4 are both pressed against the backing plate 11 to improve stability.

[0029] The outer thread sleeve of the second nut 10 is provided with a sliding sleeve 13, the outer diameter of the sliding sleeve 13 is set to match the width of the strip hole 5, and the two ends of the sliding sleeve 13 are respectively abutted against the nut end of the second bolt 9 and the opposite surface of the oblique support 4.

[0030] When the platform pedal 1 is adjusted, the sliding sleeve 13 is displaced in the strip hole 5, which can prevent the thread of the second bolt 9 from directly rubbing in the strip hole 5, thereby preventing the second bolt 9 from wearing, thereby improving its service life and stability.

[0031] The outer portion of the sliding sleeve 13 is provided with a gear ring 14 , and the gear ring 14 is located in the through groove 12 . The inner top wall of the through groove 12 is provided with a row of tooth grooves 15 engaged with the gear ring 14 . When the second bolt 9 displaces in the strip hole 5 , the gear ring 14 rolls in the through groove 12 .

[0032] By providing the toothed ring 14 and the toothed groove 15, during the adjustment of the platform pedal 1, the toothed ring 14 rolls on the toothed groove 15, thereby causing the second bolt 9 and the second nut 10 to rotate. After the platform pedal 1 is adjusted, the second bolt 9 and the second nut 10 are tightened, and the toothed ring 14 cooperates with the toothed groove 15 to lock the second bolt 9 and the second nut 10 in the circumferential direction. Therefore, when the second nut 10 is directly rotated to loosen it without other external force, the second bolt 9 and the second nut 10 cannot be loosened directly by axial displacement due to their own threaded cooperation. In this way, a more stable locking effect is achieved, thereby improving the stability and safety of the support of the platform pedal 1.

[0033] The inner ring of the gear ring 14 is provided with a plurality of retaining grooves 16 arranged in a circular array. The surface of the sliding sleeve 13 located within the through slot 12 is provided with retaining blocks 17 corresponding one-to-one with the retaining grooves 16. The retaining grooves 16 are fitted over the retaining blocks 17. The cooperation between the retaining grooves 16 and the retaining blocks 17 allows the gear ring 14 to be directly fitted over the sliding sleeve 13, forming a circumferentially fixed position relative to the sliding sleeve 13. This arrangement facilitates installation and removal.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
