Technical field
The utility model relates to a kind of winch, but is a kind of furnace of calcium carbide winch of self-locking specifically.
Background technology
Furnace of calcium carbide is mainly used in the production of industrial calcium carbide, and its keystone configuration comprises body of heater and many electrodes that are arranged in the furnace of calcium carbide, produces electric arc by after the electrifying electrodes during work, and the high temperature that forms by electric arc makes raw material generation reaction in the stove, generates calcium carbide.Wherein electric arc is mainly controlled by moving up and down of electrode.Wherein, the power that moves of electrode is provided with winch by furnace of calcium carbide.In the technique known, furnace of calcium carbide comprises electrical motor, cycloid speed reducer, drg, winch cylinder with winch at present.The power that electrical motor produces decelerates to needed revolution by cycloid speed reducer with revolution, and obtains big torque, behind drg, is reached the purpose of traveling electrode by the winch cylinder.
This furnace of calcium carbide with the shortcoming of winch is: cycloid speed reducer does not possess auto-lock function, because the weight of electrode is excessive, make electrode after braking, substantially all creeping phenomenon can take place, the shift position inaccuracy that has caused electrode, thereby influenced the work efficiency of furnace of calcium carbide, the calcium carbide nonconformity of production.
The utility model content
The technical problems to be solved in the utility model is: but a kind of furnace of calcium carbide winch of self-locking is provided, can avoid causing the electrode creeping phenomenon that takes place behind the motor braking because electrode is overweight.
But a kind of furnace of calcium carbide winch of self-locking, comprise: electrical motor, foundation brakes, winch cylinder, it is characterized in that: but also comprise the worm-gear speed reducer of a self-locking, electrical motor is connected with worm-gear speed reducer, worm-gear speed reducer is connected by coupler with the winch cylinder, and foundation brakes is positioned on the input shaft of worm-gear speed reducer.
The beneficial effects of the utility model are: but owing to adopted the worm-gear speed reducer of self-locking, make after the reductor braking, because electrode generation creeping phenomenon has been avoided in the existence of auto-lock function, thereby make that the electric arc generation of furnace of calcium carbide is more accurate, produce up-to-standard calcium carbide.
Further, consider the safety control problem, on described coupler, also be provided with brake equipment, make and have the effect of multiple braking, in the drg braking failure of the input shaft of worm-gear speed reducer or when situations such as worm-gear speed reducer mouth circuit breaks take place, can brake the safety that guarantees electrode position to the coupler place, avoid electrode unplanned motion to occur, produce up-to-standard calcium carbide.
Further again, consider the auto-lock function of worm-gear speed reducer and the problems such as simplicity of manufacturing, modulus in the described worm-gear speed reducer is 1mm, width between centers is 50mm, the diameter of worm screw is 18mm, the number of worm screw is 1, the number of teeth of worm gear is 82, and the modification coefficient of worm gear is 0, and the lead angle of worm screw is 3 ° 11 ' 38 "; the material of the worm screw of described worm-gear speed reducer is a steel; the material of the worm gear of worm-gear speed reducer is a cast iron, owing to adopted basic specification and the coupling thereof of national common worm screw, makes to manufacture than being easier to; owing to adopted steel and cast iron respectively as the material of worm and worm wheel; so the friction coefficient of worm and gear is between the 0.1-0.3, and its friction angle is greater than 5 °, can self-locking; avoided the generation of creeping phenomenon, produced up-to-standard calcium carbide.
Further again, consider that winch is to self-locking reliability requirement height, in order to guarantee safety in production, the mouth of described lifting drum also is provided with auxilliary drg, can operate the auxilliary drg of the mouth of lifting drum under the situation that any in front parts break down brakes, guarantee that motor unplanned motion can not occur, produces up-to-standard calcium carbide.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the mouth of motor 1 is provided with a foundation brakes 2, the energy output of motor 1 is transferred to worm-gear speed reducer 3 by drg 2, be provided with coupler 4 between worm-gear speed reducer 3 and the winch cylinder 5, coupler 4 is given winch cylinder 5 torque transfer that worm-gear speed reducer 3 reductions of speed increase behind the square, and 5 pairs of electrodes 7 of winch cylinder apply power and make electrode 7 reach our position of plan to produce the electric arc that we need.
Also be provided with a brake equipment on the coupler 4, when motor 1 and worm-gear speed reducer 3 or transmission lines therebetween break down, brake, prevent motor generation creeping phenomenon.
Also be provided with auxilliary drg 6 between winch cylinder 5 and the electrode 7, can operate during any parts et out of order to winch cylinder 5 between when motor 1 and assist drg 6 and brake and guarantee that electrode unplanned motion can not occur.
About the parameter of worm-gear speed reducer 3 and the selection of material, we adopt following scheme.
By the worm mechanism condition of self-locking as can be known, the relative size of the friction angle β of the friction pair that worm indexing cylinder lead angle α and worm and wormwheel are formed has determined that can mechanism self-locking.
The lead angle α of worm screw has the worm screw geometric parameter to determine that establishing a number of threads is Z1, and circular pitch is PX, and reference diameter is d1, and modulus is m, and characteristic coefficient is q, then:
tgα＝Z1PX/πd1＝Z1mπ/πmq＝Z1/q
Wherein take self-locking structure owing to us, so Z1 is 1, and, national Specification, after Z1 determined, q had corresponding respective value, therefore, modulus in the worm-gear speed reducer that we adopt is 1mm, and width between centers is 50mm, and the diameter of worm screw is 18mm, the number of worm screw is 1, the number of teeth of worm gear is 82, and the modification coefficient of worm gear is 0, and the lead angle of worm screw is 3 ° 11 ' 38 ".
Friction angle β depends on tangent direction friction power F and the ratio of normal force N, i.e. friction coefficient f, just the tg β=F/N=Nf/N=f between the two contact objects.
When β forms self-locking greater than α the time, because tgx is an increasing function, get final product greater than Z1/q so only require f, so we select steel and cast iron respectively as the material of worm and worm wheel, make that f is between 0.1 to 0.3.
As making according to coming worm-gear speed reducer is made.
Above-described only is preferred implementation of the present utility model, should be pointed out that for a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement:
Such as, influence the establishment that friction coefficient f guarantees condition of self-locking by control to the surface quality of the manufacturing materials of worm and gear;
Such as, change the establishment of guaranteeing condition of self-locking by lubricating status to the material surface of worm and gear;
Such as, by the control of squad's sliding velocity between friction pair being guaranteed the establishment of condition of self-locking;
These also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
