Above-mentioned explanation only is the general introduction of technical solution of the present invention, for can clearer understanding technological means of the present invention, and can be implemented according to the content of specification, below with preferred embodiment of the present invention and cooperate accompanying drawing to be described in detail as follows.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is the structural representation of embodiment of the invention when bolt is heated.
Fig. 2 is that the embodiment of the invention is at the prefiring structural representation of burner.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail.
As shown in Figure 1, this flame heating tool for bolt in deep hole comprises a sleeve 3, be fixedly connected with an outer-hexagonal head 2 on sleeve 3 upper surfaces, the lower surface of sleeve 3 also is fixedly connected with a connection piece 11, and connector 11 is provided with an endoporus corresponding with the cover cap nut shape.Also be provided with a circular cylinder 1 in the sleeve 3, circular cylinder 1 is fixed on the outer-hexagonal head 2, and the bottom of sleeve 3 also is provided with several steam vents 13.Be provided with a riser 6 in sleeve 3, riser 6 is connected with the piston rod of circular cylinder 1 by connecting rod 4, and circular cylinder 1 can drive riser 6 and move up and down in the inner chamber of sleeve 3.Riser 6 is provided with a burner 7, and burner 7 is provided with nozzle 16.One group of air inlet pipe of burner 7 is stretched out in sleeve 3 by the cavity of circular cylinder 1, and air inlet pipe is provided with magnetic valve, and magnetic valve is connected (not shown) with a controller.
Also be provided with one in the sleeve 3 and cut off part 9, cut off part 9 and be fixedly connected with sleeve 3, cut off the below that part 9 is positioned at riser 6, cut off part 9 and be provided with a High Temperature Gas conduit 12, High Temperature Gas conduit 12 is corresponding with the position of burner 7 top nozzles 16.Also be provided with an electronic ignition device 8 on partition part 9, electronic ignition device 8 is fixed on the partition part 9 corresponding with the position of burner 7, and an end of electronic ignition device 8 passes riser 6 and is slidingly connected with this riser 6.The cavity of the wire of electronic ignition device 8 by circular cylinder 1 stretches out with controller in the sleeve 3 and is connected (not shown).
