This embodiment provides a ground transportation device for the oxygen gun 400, including at least two trolleys 100, the trolley 100 includes a bottom plate 110, wheels 120 arranged below the bottom plate 110, support side plates 130 arranged above the bottom plate 110, a support base 140 connected to the support side plates 130, and a clamping block 150 for cooperating with the support base 140 to clamp the oxygen gun 400 on the support base 140, the support base 140 has a mounting groove 141, the mounting groove 141 is a V-shaped opening facing upward, and the clamping block 150 has a structural groove 151, and the structural groove 151 is an inverted V-shaped opening facing downward.

[0028] Since the ground transport device for the oxygen lance 400 includes at least two trolleys 100, the trolley 100 includes a bottom plate 110, wheels 120 arranged below the bottom plate 110, a support side plate 130 arranged above the bottom plate 110, a support base 140 connected to the support side plate 130, and a clamping block 150 for clamping the oxygen lance 400 on the support base 140 in cooperation with the support base 140, the oxygen lance 400 can be supported by the support base 140 and transported, and the oxygen lance 400 can be clamped on the support base 140 by the clamping block 150, so that the shaking of the oxygen lance 400 can be avoided, and the safety of ground transport of the oxygen lance 400 is improved. Since the support base 140 and the clamping block 150 are both V-shaped, oxygen lances 400 of different sizes can be clamped, which can improve the applicability of the ground transport device for the oxygen lance 400.

[0029] The support base 140 is rotatably connected to the support side plate 130 , and a rotation axis of the support base 140 is perpendicular to an axis of the oxygen lance 400 .

[0030] The number of the trolleys 100 is two.

[0031] Preferably, the distances between the rotation axis of the supporting base 140 and the bottom plate 110 in the two carts 100 are not equal, and the cart 100 with the smaller distance is provided with a baffle 160 in the direction away from the other cart 100, so that the transportation of the oxygen gun 400 can be facilitated while preventing the oxygen gun 400 from moving.

[0032] The support base 140 is provided with a stud 171 , and the stud 171 passes through the clamping block 150 and is connected to a nut 172 to lock the clamping block 150 on the support base 140 .

[0033] The number of the studs 171 is two, and the two studs 171 are respectively disposed on both sides of the mounting slot 141 .

[0034] The bottom plate 110 has an axle 180 , on which the wheel 120 is mounted. The axle 180 is perpendicular to the axis of the oxygen lance 400 .

[0038] The traction assembly includes a driving drum 310, a fixed pulley 320, a steel wire rope 330, and a driving member 340 for driving the driving drum 310 to rotate. The driving drum 310 and the fixed pulley 320 are respectively arranged at the front end and the rear end of the track 200. The steel wire rope 330 is wound around the driving drum 310, one end of which is connected to the front end of the trolley 100, and the other end passes through the fixed pulley 320 and is connected to the rear end of the trolley 100. In this way, the driving drum 310 can be driven to rotate by the driving member 340, thereby tightening the steel wire rope 330 and pulling the trolley 100 to move forward or backward.

[0039] The traction assembly further includes a speed reducer 350 , and the driving member 340 drives the driving roller 310 to rotate via the speed reducer 350 .

[0040] The working process of the oxygen lance 400 ground transport device in this example is as follows:
