[0022] See also Figure 1-5 The utility model provides an embodiment: a gas cutting mobile vehicle, comprising a mobile frame 1, on which a placing frame 3 is rotatably mounted; one end of the placing frame 3 is connected to an axle pin hole 12 provided on the bottom surface of the mobile frame 1 through an axle pin seat 11; after the placing frame 3 is laid down, its back side abuts against the upper end of the mobile frame 1, and a moving wheel 13 is provided on the side of the mobile frame 1 away from the placing frame 3; a hook 4 is also provided on the back of the placing frame 3, and the oxygen tube and the acetylene gas tube are fixed to the placing frame 3 through the hook 4;

[0023] In summary, after the oxygen cylinder and the acetylene cylinder are placed on the placement rack 3, the placement rack 3 is then turned down so that the back of the placement rack 3 contacts the upper end of the movable rack 1, thereby providing a stable placement position for the oxygen cylinder and the acetylene cylinder; the phenomenon that the bottle mouths of the oxygen cylinder and the acetylene cylinder swing up and down when the movable rack moves is completely eliminated;

[0024] At the same time, the movement of the mobile frame 1 can prompt the oxygen cylinder and the acetylene cylinder to move on the ground, so that the cutting torch can cut the workpiece farther away; at the same time, the setting of the hook 4 can coil the oxygen pipe and the acetylene gas pipe on the hook 4 to avoid the pipeline interfering with the normal movement of the equipment when the equipment moves, protecting the pipeline while making the movement of the equipment simple and convenient.

[0025] In particular, since the gas cylinders are tilted and placed on the placement rack 3 when the device is moved and used, the center of gravity of the device is low when the device is moved and placed, and even if there is an external force impact, the gas cylinders will not fall over.

[0026] Furthermore, since a positioning seat 8 is also provided at the upper end of the mobile rack 1, and a positioning pin 7 is also provided at the back of the display rack 3; the display rack 3 is fixed to the mobile rack 1 after the pin passes through the positioning seat 8 and the positioning pin 7, the display rack 3 can be further fixed to the mobile rack 1 by the pin, so that the display rack 3 will not swing when the mobile rack 1 moves, so as to ensure the safety of the gas cylinder.

[0027] In order to ensure that the gas cylinders are stable and reliable when being moved and used, especially to avoid the problem of collapse of the gas cylinders when the cutting torch pipeline pulls the gas cylinders; a first support seat 9 is provided above the cover plate 2 and the display rack 3 to fix the oxygen cylinders and acetylene cylinders on the display rack 3.

[0028] Furthermore, a fastener 6 is provided which passes through the cover plate 2 and is connected to the first support seat 9 so as to fasten the cover plate 2 to the oxygen cylinder and the acetylene cylinder.

[0029] In summary, when the fastener 6 passes through the cover plate 2 and is connected to the first support seat 9, the cover plate 2 can be covered on the gas cylinder. At the same time, the first support seat 9 and the cover plate 2 cooperate with each other under the action of the fastener 6 to hold the outside of the gas cylinder tightly, so that the stability of the gas cylinder can be reliably and stably guaranteed; wherein, the fastener 6 is preferably a screw, one end of which is threadedly connected to the internal threaded hole on the first support seat 9, and the other end passes through the cover plate 2 and is connected to the nut. Based on this, the above method can ensure the stability of the gas cylinder, and even if there is external traction and impact, it will not cause the gas cylinder to collapse.

[0030] On the basis of the above solution, since a support plate 14 is further provided at the bottom of the display rack 3, and a semicircular second support seat 10 is further provided on the support plate 14, the stability of the gas cylinder on the device can be further ensured.

[0031] In addition, since the mobile frame 1 is also provided with a pull rod 5, and the mobile frame 1 is moved on the ground by pulling the pull rod 5, the user does not need to bend down to operate the device when moving, so it is more convenient to use than the prior art.

[0032] Furthermore, since there are two hooks 4 and the two hooks 4 are symmetrically installed on the display rack 3, the pipeline of the cutting torch has multiple fixed points, so that after the pipeline is coiled, it can be stably and reliably located on the display rack 3. At the same time, the pipeline coil is placed on the display rack 3, so that the pipeline will not interfere with the rotation of the display rack 3, effectively solving the problem of the display rack 3 being pulled by the pipeline during the flipping process.

[0033] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments.
