Abstract
The utility model relates to a stroke conversion device for an iron notch drilling machine for blast furnaces, which comprises an outer casing. The outer casing is provided with a first worm and a second worm inside. A tension steel wire with one end fixedly connected with the first worm is wound on the first worm. The other end of the tension steel wire penetrates through the outer casing and exposes out of the outer casing. The first worm is provided with a reset spring and is in mesh transmission with the second worm through a speed-variable gear. A shaft of the second worm extends out of the outer casing to form an output end. The stroke conversion device can be mounted in a safety area distant from the blast furnaces and can be connected with detection equipment, action stroke of an action device of the iron notch drilling machine is converted into angular displacement by the stroke conversion device, and automation and standardization of control of the iron notch drilling machine are realized beneficially.
Description
Technical field
The utility model relates to a kind of stroke transfer equipment, and especially a kind of stroke transfer equipment that is used for blast furnace open hole machine belongs to blast furnace automatic control technology field.
Background technology
Blast furnace open hole machine is a kind of equipment that is used for opening the blast furnace stifled iron notch, and its course of action and principle are similar to rock drill, and the function that realizes at last is the rotation through oil motor, makes drill steel chisel the stemming of blast furnace stifled iron notch, and molten iron is flowed out.
In common technology, the mode of iron perforater is adopted two kinds: 1, each process of electrical control iron perforater, promptly operate electric button by job order, realize that the hydraulic buttery valve of respectively controlling of iron perforater gets electronic work.Can be extended out thus through wireless remote mode, stand in the blast furnace iron notch next door, seeing on-the-spot actual state by the workman; Remote controller; This method on control degree than more directly perceived in operation room operation, but have potential safety hazard, also exist the concrete operation steps can not stdn simultaneously; All processes all lean on workman's experience to grasp, and do not meet the requirement of the preceding operational standardization of State of Blast Furnace.2, manually control SV valve platform by the workman in that remote control is indoor, through with the cooperation of field worker, realize the course of action of iron perforater, this operating method relies on workman's experience and cooperation fully, can not realize stdn.Because the blast furnace taphole temperature is very high; Test set (for example: position feedback near switch; The electronic products such as photoelectric encoder that rotation detects) thus can at high temperature burn the scene that can't be applied to, so prior art all is confined to manual control, hindered standardized realization.
The utility model content
The purpose of the utility model is: to the problem of above-mentioned prior art existence; A kind of stroke transfer equipment that is used for blast furnace open hole machine is proposed; Can convert the actuating length of blast furnace open hole machine into angular travel, help the robotization and the stdn of iron perforater control.
In order to reach above purpose, the technical scheme of the utility model is following:
A kind of stroke transfer equipment that is used for blast furnace open hole machine; Comprise shell; It is characterized in that, be provided with first, second worm screw in the said shell, be wound with the tractive steel wire that an end is fixedly connected with it on said first worm screw; The other end of said tractive steel wire passes shell and exposes the termination, also is provided with return spring on said first worm screw; Said first worm screw forms engaged transmission through the variable gear and second worm screw; The shaft extension of said second worm screw the hull shape of going out becomes output terminal.
During use, the tractive steel wire is connected with the movement device (like forearm, drill steel) of iron perforater, and output terminal is connected with test set (as detecting scrambler etc.).When iron perforater moves, will affect the tractive steel wire like this, and then drive the rotation of first worm screw, and make return spring produce restoring force, can after iron perforater resets, the tractive steel wire be regained; First worm screw can drive the rotation of second worm screw through variable gear when rotated, and the test set that is connected with output terminal is rotated, and makes test set obtain the angular travel data, and is sent to automatic control system, realizes monitoring and control.
The further perfect technical scheme of the utility model is following:
1. the termination of said tractive steel wire is fixedly connected with wireline, and said wireline is fixedly connected with the movement device of iron perforater after the fixed pulley break-in.
The utility model can be installed in the safety zone away from blast furnace, can link to each other with test set, and convert the actuating length of iron perforater movement device into angular travel, helps realizing the robotization and the stdn of iron perforater control.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Embodiment
The stroke transfer equipment substruction that is used for blast furnace open hole machine of present embodiment is as shown in Figure 1; Comprise shell 1; Be provided with first, second worm screw 2,3 in the shell 1; Be wound with the tractive steel wire 21 that an end is fixedly connected with it on first worm screw 2, the other end of tractive steel wire 21 passes shell and exposes on 23, the first worm screws 2 of termination and also be provided with return spring 22; First worm screw 2 forms engaged transmission through the variable gear 4 and second worm screw 3; The shaft extension of second worm screw 3 hull shape of going out becomes output terminal 31.The termination 23 of tractive steel wire 22 is fixedly connected with wireline, and wireline is fixedly connected (not shown) with the movement device of iron perforater after the fixed pulley break-in.
The action of iron perforater has three: big arm changes that into commentaries on classics is moved back, forearm mention depress, the drill steel forward-reverse.Wherein big arm is in avoids the pyritous position, directly installation and measuring equipment; And the action of other two equipment all is in the naked light; Direct installation and measuring equipment; Need on forearm and drill steel, be fixedly connected with a resistant to elevated temperatures wireline respectively, and each wireline is connected with the tractive steel wire of corresponding present embodiment device after the fixed pulley break-in.
Affect the wireline action during action of iron perforater forearm or drill steel, the tractive steel wire also can be affected, and drives first worm screw and rotate, simultaneously the return spring generation restoring force that is opened; First worm screw drives second worm screw through variable gear and rotates, and the proofing unit that be connected with output shaft this moment also can rotate, and obtains the angular travel data, and imports automatic control system into, reflects actuating length.
After iron perforater forearm or drill steel action are accomplished, lift when getting back to zero position, return spring discharges restoring force makes first worm screw reply rotation, regains tractive steel wire and wireline; First worm screw drives second worm screw through variable gear and replys rotation, and the proofing unit data that are connected with output shaft are made zero.
Present embodiment can also increase external returning spring at the back at haulage cable, guarantees to affect wireline to reply, and reduces the dependence to return spring.
Present embodiment has changed the direction of iron perforater course of action with fixed pulley, thus can be installed in the suitable environment, and can detect the concrete stroke of iron perforater device action, and then realizing stdn in the control automatically.
Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
