As shown in fig. 2, the engineering machine in this embodiment is a rotary drilling rig, and suspended walkways 3 are installed on left and right sides of the upper rotating platform 2 and left and front sides of the cab. The suspended walkway 3 is composed of one or more walkway pedals arranged in sequence.

As shown in fig. 3, the walkway treadle 3 is mainly composed of treadles 5 and pedestals 4, the treadles 5 are mainly composed of arm beams 51 which are positioned at both ends and are parallel to each other and a flat plate 52 fixedly connected with the two arm beams 51, and the end parts of the arm beams 51 are rotatably connected with the pedestals 4.

As shown in fig. 4, the support 4 includes a fixed mounting plate 41, two hinge plates 43 vertically and fixedly connected to the fixed mounting plate 41, and the two hinge plates 43 are provided with coaxial hinge holes. A pin shaft 6 is provided in the hinge hole, the arm beam 51 is hinged to the hinge plate 43 via the pin shaft 6, and a cotter pin 61 for preventing the pin shaft from falling off is mounted at the end of the pin shaft 6.

As shown in fig. 5, the arm beam 51 and the flat plate 52 of the pedal 5 are fixed by bolts, and a hinge long hole 512 is provided at an end portion of the arm beam 51, and a longitudinal direction of the hinge long hole 512 is the same as a longitudinal direction of the arm beam 51. Mounting lugs 513 for fixedly connecting with the flat plate 52 are arranged on both sides of the arm beam 51. Mounting lugs 513 are provided on both sides of the arm beam 51 so that the adjacent ends of the flat plates of two adjacent treadboards can be fixed to the same arm beam, thereby making the two adjacent walkway treadboards an integral treadboard. In addition, the arm beam 51 may be provided with a mounting lug 513 on one side for fixedly connecting with the flat plate 52, so that two adjacent walkway pallets are independent from each other, as shown in fig. 3, and the arm beam may be used at the end of the suspended walkway.

As shown in fig. 3. The end of the arm beam 51 of the pedal 3 is positioned between the two hinged plates 43 of the support 4, the pin shaft 6 passes through the hinged holes of the hinged plates 43 and the hinged long hole 512 on the arm beam 51, and the pin shaft 6 is limited by the cotter pin 61.

As shown in fig. 4 and 5, the fixed mounting plate 41 is provided with a stopper. The fixed mounting plate 41 is welded with a limiting block 45, and two ends of the limiting block 45 are respectively welded with the two hinge plates 43.
