Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment for fire fighting, and specifically to a mobile high-temperature metal flame cutting equipment. Background Art

[0002] In the field of fire fighting or other fields, flame cutting equipment is required for cutting operations. Existing flame cutting equipment often requires personnel (such as firefighters) to carry oxygen cylinders and cutting components (such as oxygen melting rods) for on-site cutting operations. The flame cutting equipment with this structural design is bulky, inconvenient for operators to use, and brings great physical energy consumption to the operators. In addition, the cutting components of existing flame cutting equipment often cannot be connected to the host that controls the cutting components on-site. Instead, the cutting components are carried into the site by the operator, and the host is placed at a place far from the site so that the host can communicate with the communication terminal. Such an arrangement brings inconvenience to on-site cutting operations, especially for the fire rescue site where it needs to be completed quickly and timely under command. Although the commander can issue operation instructions to the host and command the operator through the communication interruption, due to the long distance between the host and the cutting components, a long cable needs to be laid, and this cable is used for physical (mechanical) and electrical connection between the host and the cutting components. Summary of the Invention

Specific embodiments

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods:

[0031] As Figures 1-7 shown, a mobile high-temperature metal flame cutting device includes a cutting rod 100, a cutting torch 200, a first composite cable 300, an alligator clip 400, an arc striking plate 500, a magnetic element 600, a second composite cable 700, a control host 800, an oxygen gas source vehicle 900, and an oxygen filling tube 110. One end of the first composite cable 300 is electrically connected to the control host 800. The first composite cable 300 includes an oxygen supply line tube for oxygen supply and a power supply cable for power supply. The oxygen supply line tube and the power supply cable are integrated into one cable by wrapping, thereby forming the first composite cable 300.

[0032] The other end of the first composite cable 300 is connected to the cutting torch 200. The cutting rod 100 is connected to the cutting torch 200. The cutting torch 200 is used to enable the cutting rod 100 to generate combustion under power supply and oxygen supply, thereby performing flame cutting on the target object. It is a prior art that the cutting torch 200 enables the cutting plate to generate combustion, so the specific structure of the cutting torch 200 will not be described in detail here.

[0033] One end of the second composite cable 700 is connected to the control host 800. The second composite cable 700 is electrically connected to the first composite cable 300 through the internal circuit of the control host 800. The other end of the second composite cable 700 is used to connect to the target component. When the target component is in contact with the target object, the cutting rod 100, the cutting torch 200, the first composite cable 300, the second composite cable 700, and the target component form an electrical circuit. Among them, the first composite cable 300 serves as the positive electrode, and the second composite cable 700 serves as the negative electrode.

[0034] The target component includes an alligator clip 400, an arc striking plate 500, and a magnetic element 600, that is, the second composite cable 700 is connected to one of the alligator clip 400, the arc striking plate 500, and the magnetic element 600. The target component is used as the ignition negative electrode, and one of the alligator clip 400, the arc striking plate 500, and the magnetic element 600 can be selected according to the actual situation on site.

[0035] Exemplarily, a male connector is connected to the other end of the second composite cable 700, and a female connector adapted to the male connector is provided on the target component, so that the target component can be detachably connected to the second composite cable 700, and different target components can be switched as needed. For example, external thread joints are provided at one ends of the alligator clip 400, the arc striking plate 500, and the magnetic element 600, and an internal thread joint is provided at the other end of the second composite cable 700, so that any one of the alligator clip 400, the arc striking plate 500, and the magnetic element 600 can be quickly and detachably connected to the second composite cable 700 through the threaded connection between the internal thread joint and the external thread joint.

[0036] The control host 800 is used to control the oxygen supply and power supply to the cutting torch 200, including whether to supply power (supply power and stop supplying power) and whether to supply oxygen. Whether to supply oxygen includes supplying oxygen, stopping oxygen supply, and adjusting the oxygen supply amount. The power supply for power supply comes from an external power supply. For example, an external commercial power supply is first connected to the control host 800 and then supplies power to the cutting torch 200 through the internal circuit of the control host 800. The internal circuit of the control host 800 can implement functions of overcharge protection, over-discharge protection, short-circuit protection, and over-current protection.

[0037] Exemplarily, the control host 800 includes a video recording device, a positioning device, and a communication device. The video recording device has a night vision video recording function. The video recording device can be connected to the outside in real time through the communication device, and the current location of the control host 800 can be determined in real time through the positioning information sent by the positioning device.

[0038] Exemplarily, the control host 800 is internally provided with a power supply. The rated output voltage of the power supply is 12V (volt).

Each oxygen cylinder 13 is vertically fixed or detachably installed in the cavity, and each oxygen cylinder 13 can be in contact with each other or arranged separately. For example, four oxygen cylinders 13 are provided, and the four oxygen cylinders 13 are all vertically arranged in parallel at intervals.

[0040] The oxygen outlet end of the oxygen cylinder 13 is connected to the input end of the pressure reducer assembly 15, so that the oxygen in the oxygen cylinder 13 flows out through the outlet end and then into the pressure reducer assembly 15. The pressure reducer assembly 15 includes an output end 16, and the output end 16 of the pressure reducer is used to be connected to the input end of the long tube 9 to output oxygen to the long tube 9. The gas outlet end of the long tube 9 is used to be connected to an external device, so as to supply oxygen to the external device. For example, by connecting the gas outlet end of the long tube 9 to a cutting torch, oxygen is supplied to the cutting torch.

When the cylinder valve is closed, the oxygen delivery amount is 0, that is, no oxygen can be delivered to the pressure reducer assembly 15. When the cylinder valve is fully closed, the oxygen is delivered at the maximum oxygen delivery speed. When the cylinder valve is partially opened, the oxygen delivery amount is between 0 and the maximum oxygen delivery speed.

[0044] The long tube 9 is wound and installed on a hose reel 10, and the hose reel 10 is movably installed in the cavity of the vehicle body 1, so as to facilitate moving the hose reel 10 out of or into the cavity, thereby facilitating the maintenance and replacement of the long tube 9 reel.

[0045] Exemplarily, a hand crank 5 is further included. The hand crank 5 is in transmission connection with the hose reel 10. The hand crank 5 is used to drive the hose reel 10 to rotate forward and backward to wind up the long tube 9 around the hose reel 10 and to unwind the long tube 9 wound around the hose reel 10.

[0046] Exemplarily, a support frame (not shown in the figure) is further included. The support frame includes a cross beam plate 4 and a handle 2. The cross beam plate 4 is fixedly installed at one end of the hose reel 10, and both ends of the cross beam plate 4 are also fixedly connected to the handle 2. The hose reel 10 is installed on the support frame through the cross beam plate 4. The hand crank 5 passes through the cross beam plate 4 and is in transmission connection with the hose reel 10.

[0047] Exemplarily, a slide rail 7 assembly is further included. The slide rail 7 assembly is installed on the vehicle floor 12 of the cavity of the vehicle body 1, and the support frame is installed on the slide rail 7 assembly.

[0048] The slide rail 7 assembly includes a slide rail 7 and a slide rail groove 8. The slide rail groove 8 is fixedly installed on the vehicle floor 12, and the slide rail 7 is slidably installed on the slide rail groove 8, enabling the slide rail 7 to slide along the slide rail groove 8 and slide out of the slide rail groove 8. The support frame is fixedly connected to the slide rail 7, thereby installing the support frame on the slide rail 7 assembly.

[0049] Through the slide rail 7 assembly, the operation convenience is increased, facilitating the movement of the hose reel 10 and the long hose 9 on the hose reel 10.

[0050] Exemplarily, it further includes a positioning ball 11, and the positioning ball 11 is fixedly installed at the end of the long hose 9. Through the positioning ball 11, the hose can be well protected from being damaged.

[0052] Exemplarily, it further includes a vehicle handle 3, and the vehicle handle 3 is movably connected to the front end of the vehicle body 1. The vehicle handle 3 can be flipped relative to the vehicle body 1, enabling the vehicle handle 3 to approach or move away from the vehicle body 1. The vehicle handle 3 can be close enough to completely fit the vehicle body 1, thus saving occupied space.

[0053] Exemplarily, it further includes a high-pressure gauge 19 and a medium-pressure gauge 20. The high-pressure gauge 19 and the medium-pressure gauge 20 are installed at the rear end of the vehicle body 1. The high-pressure gauge 19 is connected in communication with the pressure reducer assembly 15 through a high-pressure hose 17, and the medium-pressure gauge 20 is connected in communication with the pressure reducer assembly 15 through a medium-pressure hose 18. The high-pressure gauge 19 measures the oxygen pressure output by the pressure reducer at high pressure currently, and the medium-pressure gauge 20 measures the oxygen pressure output by the pressure reducer at medium pressure currently.
