Description

Iron residue tapping machine

The specific equipment of putting the molten iron mouth was dug in residual iron pond before the utility model belonged to steelmaking furnace.

Over a long time, residual iron pond is dug and to be put the molten iron mouth and manually carry out mostly, manually digs under high temperature, narrow environment, and the speed of not only digging is slow, and labour intensity is big, particularly during the broiling summer, more allows the people be difficult to stand.

The purpose of this utility model is to produce actual needs, and a kind of artificial new exclusive equipment---residual iron taphole drilling machine that molten iron is put in residual iron pond of digging that substitutes is provided.

Reaching of the utility model above-mentioned purpose, implemented following scheme:

This equipment is supporting body with guide rail 9, and fuel tank 3 is welded on the back upper place of guide rail 9; Hydro-pump 6 and electric motor 8 are installed in the two ends of coupling flange 19 respectively, middle link by shaft coupling, coupling flange 19 be welded on guide rail 9 above; Fuel tank 3 communicates with the oil-in of hydro-pump 6; Integrated operating valve 7 is erected at a side of guide rail 9; Rig balladeur train 4 is installed in the downside of guide rail 9, molten iron mouth rig 5(molten iron mouth rig 5 is installed on the balladeur train 4 is comprised having rotary fluid motor M1 and the knocker I that makes its revolution and impact function), the front end of drilling rod 11 is equipped with drill bit 13, the bit shank of its rear end and molten iron mouth rig 5 links, and passes through carriage 12 with its picking-up; Advancing hydraulic pressure motor 1 is installed in the rear end of guide rail 9, links with rig balladeur train 4 by sprocket wheel 20 and the chain 21 that links with it.

Be further described below in conjunction with accompanying drawing:

Fig. 1---the residual iron taphole drilling machine of the utility model front view;

Fig. 2---the residual iron taphole drilling machine of the utility model mansion view;

Fig. 3---the residual iron taphole drilling machine of the utility model hydraulic system principle figure.

Fig. 1 and Fig. 2 have described the complete machine structure of residual iron taphole drilling machine.This machine is a supporting body with guide rail 9, and its rear end is pressed on the rear support 2 that is fixed in the ground, and connects fixing with it with latch 18; Front end is supported on the preceding bearing 15 that is fixed on the residual iron pool wall 17 by adjusting handwheel 14, and handwheel is adjusted in rotation can make guide rail 9 be horizontal; Fuel tank 3 is welded on the back upper place of guide rail 9; Hydro-pump 6 and electric motor 8 are installed in the two ends of coupling flange 19 respectively, middle link by shaft coupling, coupling flange 19 be welded on guide rail 9 above; Fuel tank 3 communicates with the oil-in of hydro-pump 6; Integrated operating valve 7 is erected at a side of guide rail 9, manually operated directional valve F1 has been installed on it, F3, F5 and one-way throttle F2, F4, and one-way relief valve F6, realize operation and adjusting control to this equipment work, rig balladeur train 4 is installed in the downside of guide rail 9, molten iron mouth rig 5(molten iron mouth rig 5 is installed on the balladeur train 4 comprises having rotary fluid motor M1 and the knocker I that makes its revolution and impact function), balladeur train 4 can move forward and backward along guide rail 9 together with rig 5; Advancing hydraulic pressure motor 1 is installed in the rear end of guide rail 9, links with rig balladeur train 4 by sprocket wheel 20 and the chain 21 that links with it, and propulsion motor 1 revolution, drive sprocket 20 and chain 21 drag rig balladeur train 4 and advance, retreat along guide rail 9 together with molten iron mouth rig 5; Chain 21 front ends are provided with chain tension screw rod 10, regulate the tensioning degree that it then can adjust chain 21; The front end of drilling rod 11 is equipped with drill bit 13, and the bit shank of its rear end and molten iron mouth rig 5 links, and by carriage 12 it is held up, and makes it to keep the direction parallel with guide rail 9 to move, thereby guarantees the accurate drilling direction of molten iron mouth.

It is full hydraulic drive that Fig. 3 has described this residual iron taphole drilling machine, it is to produce high-pressure oil by motor-driven hydraulic pumps, carries out work by the handle of operating integrated operating valve 7.

(1) propelling of molten iron mouth rig 5 and rollback motion

The handle of manually operated directional valve F5 on the integrated operating valve 7 is pushed " the next " among Fig. 3, high-pressure oil is sent out F6 through reducing valve and is entered advancing hydraulic pressure motor M2 and make its revolution, by sprocket wheel 20 and chain 21 transmissions, molten iron mouth rig 5 advances along guide rail 9, make drill bit 13 convergence working faces, its propulsive force can be adjusted by reducing valve F6; This handle is pushed " upper " among Fig. 3, high-pressure oil enters advancing hydraulic pressure motor M2 through throttling valve F4 again, and in like manner, molten iron mouth rig 5 is return along guide rail, makes drill bit 13 away from working face, and its speed of returning can be adjusted by throttling valve F4.

(2) turning motion of drilling rod 11 and drill bit 13

The handle of manually operated directional valve F3 on the integrated operating valve 7 is pushed " upper " among Fig. 3, high-pressure oil enters the oil motor M1 that is contained on the molten iron mouth rig 5 by throttling valve F2, make its revolution, driving drilling rod 11 and drill bit 13 is just changeing, its positive rotary speed can be adjusted by throttling valve F2, otherwise, this handle is pushed " the next " among Fig. 3, oil motor M1 drives drilling rod 11, drill bit 13 counter-rotatings.

(3) control of hydraulic pressure molten iron mouth rig 5

The handle of manually operated directional valve F1 on the integrated operating valve 7 is pushed " upper " among Fig. 3, because the logical oil return of the control oil circuit (dotted line among the figure) of rig 5, little pressure oil enters rig 5, through being loaded on the flat valve on the rig 5, make rig 5 piston back cavities replace into pressure oil, rig 5 is in light impact conditions; Again its handle is pushed " meta ", at this moment, the control oil circuit of rig 5 (dotted line among the figure) leads to high-pressure oil, makes a large amount of pressure oils enter rig, and in like manner, rig 5 is in the state of beating again; Again its handle is pushed " the next ", rig 5 is in halted state.

The residual iron tapping machine of the utility model has shown following advantage in trial-production is used:

This equipment replacement artificial cutting operation, greatly improved cutting speed, improved workman's operating condition, improved the Mechanization Level that the stokehold produces; This residual iron tapping machine is reasonable in design, simple and compact for structure, easy to operate, stable work in work.
