Abstract
The utility model relates to a portable torch-cutting machine, comprising a cutting torch 1, a gas combusting rubber hose 2, an oxygen rubber hose 3, an oxygen pressure reducer 4, a micro high tension oxygen bottle 5, a micro gas combusting bottle 6, a work-position device 7 and a toolbox 9. The utility model has the advantages of portability, complete matched tools and high efficiency, and the whole operating time is only 15 minutes. Various fuel gas, such as liquefied petroleum gas, acetylene, butane, natural gas, etc. can be used by the utility model. The utility model is suitable for the first-aid repair of lines and the repair welding work of rails, tongue rails and track switches in each work areas, such as labour and electricity.
Description
The utility model belongs to the improvement of flame-type cutting machine.
The portable flame cutting machine is suitable for needing promptly to cut steel in work high above the ground, field work and the various rescue, uses during as rail, steel pipe.Be particularly suitable for the on-the-spot rail that breaks that takes place suddenly of railway, use when needing the rush repair circuit.
At present, the interim processing of disconnected rail on the rail track is generally adopted by " first aid device ".But first aid device poor reliability can not guarantee traffic safety.Especially the rail level " is taken off lid " or rail crack more powerless.Existing flame cutting machine, because of volume is big, heavy, inconvenience is used for the repairing of rail track.
The purpose of this utility model provides a kind of portable flame cutting machine.This machine only needs a people can transport to the scene, has shortened the repairing time greatly.The not only small volume and less weight of this machine, suitable bicycle carries, and supporting apparatus is complete, the cutting efficiency height.Only 15 minutes synthetic job time.Can guarantee traffic safety.This machine also is suitable for soldering work and other repair work that the worker is engaged in, rail, tongue, track switch abrasion are carried out in each work area of electricity affair.If change torch head into soldering tip, then can make welding machine and use.
The mechanism of flame-type cutting machine:
The flame-type cutting machine is by the suction effect of penetrating of cutting torch, the heat that makes fuel gas such as liquefied petroleum gas, propane, butane, acetylene and combustion-supporting gas such as oxygen fully mix after-combustion to be produced is to being cut material, as rail, be heated to ignition temperature, and the inject high pressure Oxygen Flow, impel the incision steel in fierce oxidizing process, to aggravate spontaneous combustion.Meanwhile, under the impact of hyperbaric oxygen jet, metal oxide slag is disposed, rail is disconnected.
The portable flame cutting machine can use multiple fuel gas.As liquefied petroleum gas, propane, butane, acetylene and natural gas etc.
Below in conjunction with accompanying drawing the utility model is described in detail as follows:
Fig. 1 is a portable flame cutting machine structure schematic diagram
Fig. 2 is the strong and weak cutting torch emitter construction figure of adjustable solar term stream
Fig. 3 is a double-layer flame cutting torch structure chart
The utility model is made up of cutting torch 1, gas hose 2, oxygen hose 3, oxygen pressure reducer 4, high-pressure mini oxygen cylinder 5, miniature gas bottle 6, station device 7 and tool box 9.
One end of gas hose 2 is connected with the gas joint of cutting torch 1, and the other end is connected with the out splice going splice of miniature gas bottle 6. By black gas hose 2 to cutting torch 1 transportation work combustion gas. One end of gas hose 3 is connected with the oxygen connection of cutting torch 1, and the other end is connected with the out splice going splice of oxygen pressure reducer 4. Carry combustion-supporting gas oxygen by red rubber oxygen hose 3 to cutting torch 1. Oxygen pressure reducer 4 is the oxygen pressure regulators that are contained on the high-pressure mini oxygen cylinder. Control to the flow of the oxygen of cutting torch 1 conveying by it. In high-pressure mini oxygen cylinder 5, filled 14.71MPa, i.e. 150Kgf/cm2Oxygen. It is to cut with combustion-supporting gas holder. Miniature gas bottle 6 is Cutting Gases holders, can fill the fuel gas such as liquefied petroleum gas, propane, butane and natural gas in the bottle. Or the safety that connects miniature dissolved acetylene bottle supplies acetylene gas. Station device 7 is used for placing high-pressure mini oxygen cylinder 5 and miniature gas bottle 6. Above-mentioned whole utensil can be placed in the portable toolbox 9. For working conveniently, placed an industrial oxygen in the tool box 9 and filled canister 8, in order to the oxygen in the big oxygen cylinder is filled with in the high-pressure mini oxygen cylinder 5.
The strong and weak cutting torch injector of adjustable solar term stream is made up of De Laval noz(zle) 10, adjustable needle valve 11, unsteady flow mouth 12 and valve body 13.
The double-layer flame cutting torch is made up of mouth 15, cutting oxygen airway 16 and rifle headstock 17 in the outer mouth 14 of cutting torch, the cutting torch.
Embodiment:
The oxygen cylinder diameter is φ 140mm, long 400mm, and heavy 7Kg, 4 liters of volumes, acetylene cylinder, diameter are φ 140mm, long 400mm, heavy 10Kg, 4 liters of volumes.The long 480mm in tool box, wide 140mm, high 420mm, heavy 8.5Kg.
The utility model compared with prior art has the following advantages:
1, preheat flame can adopt oxygen-liquefied petroleum gas mixing flame, oxy-acetylene mixing flame, oxygen-natural gas mixing flame, oxygen-propane mixing flame and oxygen-various gas flames such as butane mixing flame. This greatly facilitates the user.
2, the cutting torch on the cutting torch has adopted channel structure, has formed double-layer flame, i.e. annular flame and reinforcement flame. This double-layer flame has following three advantages:
(1) because of the fuel gases calorific value difference, can make various gas give full play to fuel factor.
(2) adopt annular flame and strengthen flame, heating and cutting are almost carried out synchronously, increased the thermal efficiency of cutting torch 1, shortened preheating clipping time.
(3) dual flame directly around high pressure cutting oxygen jet, has been protected the purity of oxygen jet in cutting process, has strengthened vigorous oxidation and the hypergolic reaction of oxygen jet to the steel otch, has promoted to have saved to the speed of deep layer cutting the consumption of gas.
(4) simplified connected mode between cutting torch and the rifle headstock, not only easy to use and reliable, and saved fee of material and processing charges.
Claims (1)
1, a kind of flame cutting machine that constitutes by cutting torch, fuel gas bottle, oxygen cylinder, combustion gas sebific duct and oxygen hose etc., it is characterized in that: the injector in the cutting torch is made up of De Laval noz(zle), adjustable needle valve, unsteady flow mouth and valve body; This injector can be used to regulate the air-flow power; Cutting torch on the cutting torch has adopted channel structure, can form double-layer flame, the double-layer flame cutting torch is made up of mouth, cutting oxygen airway and rifle headstock in the outer mouth of cutting torch, the cutting torch, fuel gas bottle adopts the miniature gas bottle, oxygen cylinder adopts the high-pressure mini oxygen cylinder, cutting machine all is contained in the portable toolbox, has oxygen in the case and fills canister.
