The second rotating body 83 is engaged with the first rotating body 82, so that the rotating head 81 at the bottom end of the supporting rod 8 is prevented from being removed from the rotating groove 821, and the supporting rod 8 and the supporting platform 1 are stably connected.

In one embodiment, α is 30-45 °, such as 32 °, 35 °, 38 °, 40 ° and 42 °, to facilitate the separation rail cylinder 13 to hook the rail on the ground for separation when telescoping.

In one embodiment, β is 30-45 °, such as 32 °, 35 °, 38 °, 40 ° and 42 °, so that the traveling cylinder 2 can push the cross beam of the track on the ground to slide the sliding wheel 15 forward when extending or retracting.

As shown in fig. 1, in one embodiment, the rail conveying process of the rail conveying device of the present invention is as follows:

(1) dismounting rail bolt

Providing wind pressure to the pneumatic drill 16 by using a compressed air pipeline 17, taking the pneumatic drill 16 down from the supporting platform 1, and disassembling bolts of the track on the ground by using a bolt sleeve sleeved on a drill bit of the pneumatic drill 16;

(2) separation track

Operating a separation button on the operation valve group 3, and controlling the separation track oil cylinder 13 to extend a first hook 18 arranged at the top end of a piston rod of the separation track oil cylinder and hook a track with bolts removed on the ground so as to separate the track;

(3) machine for grabbing and lifting rail to adhesive tape

Operating a swing button on the operation valve group 3 to control the swing oil cylinder 6 to stretch and retract so as to drive the rotary operating rod 7 to horizontally move and further drive the supporting rod 8 to horizontally rotate and further drive the mechanical arm 10 to horizontally rotate and further drive the grabbing oil cylinder 12 and the grabbing hand 11 to horizontally swing to the upper part of the track on the ground;

operating a height-adjusting button on the operating valve group 3 to control the height-adjusting oil cylinder 9 to stretch and retract, so as to drive the mechanical arm 10 to swing up and down, and further drive the grabbing and lifting oil cylinder 12 and the grabbing and lifting hand 11 to swing up and down to a proper height;

operating a grabbing and lifting button on the operation valve group 3, and controlling the grabbing and lifting oil cylinder 12 to stretch and retract so as to drive the grabbing and lifting hand 11 to open and close to grab and lift the separated tracks on the ground;

then operating the swing button, the height-adjusting button and the grabbing and lifting button in sequence as described above, controlling the grabbing and lifting hand 11 to swing horizontally and swing up and down to the position of the adhesive tape machine in sequence and then open, and placing the grabbed and lifted track on the adhesive tape machine;

(4) track on dragging adhesive tape machine

Operating a dragging button on the operating valve group 3, controlling the dragging oil cylinder 4 to stretch, and extending out a second hook 20 arranged at the top end of a piston rod of the dragging oil cylinder and hooking the second hook to a track on the adhesive tape machine so as to drag the second hook to a proper position;

(5) walk

Operating a walking button on the operating valve group 3, controlling the walking oil cylinder 2 to stretch and retract, extending a pushing block 19 arranged at the top end of a piston rod of the walking oil cylinder and pushing a track on the ground to enable the sliding wheel 15 to slide forwards, so as to walk forwards;

(6) in the foregoing steps (1) - (5), the anti-toppling leg 14 is supported on both sides of the ground rail to prevent the support platform 1 from toppling;

(7) and (4) repeating the steps (1) to (6), carrying the next section of track until all the tracks are carried, and starting the adhesive tape machine to convey the tracks to the designated positions.

The track carrying device is simple in structure and convenient to use; the track bolts do not need to be disassembled manually, the tracks do not need to be separated manually, and the tracks do not need to be carried to the adhesive tape manually, so that time and labor are saved; the rail conveying efficiency is high, and the safety is good.
