Abstract
The utility model discloses a lever-type assistor for a shaft frill jumbo. The main body is non-circle eccentric gear group, which comprises a first non-circle eccentric gear (8), a second non-circle eccentric gear (7) and a third non-circle gear (6) by engaging orderly. The first non-circle eccentric gear is correspondent with the two-open type speed-reducing gears (2) and (3) and a dynamic motor belt wheel (1) by a double-direction engaged clutch (13), while the non-circle eccentric gear is provided with a crank (5), which connects with a connecting rod (4), with the rocker actuator connecting outside. The utility model is very efficient and easy to operate, and has less environmental pollution.
Description
Technical field
The utility model relates to a kind of and the matching used lever assistor of drilling machinery.
Background technology
Trepan generally is made of frame, hoisting equipment, impact device, gear, engine etc., it has more and more given play to important function in the drought resisting of rural area, but existing percussive open-well machine exists mating power bigger, fuel consumption is bigger, the cost height, inefficiency, and air caused serious deficiencies such as pollution.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model provides a kind of energy conservation, reduces the lever assistor that is used for trepan that pollutes, improves the trepan operating efficiency.
The technical scheme in the invention for solving the above technical problem is: it is based on a non-garden eccentric gear group, this non-garden eccentric gear group is made of the non-round eccentric gear 8 in intermeshing successively first road, three roads, non-garden, second road eccentric gear 7, the 3rd road non-circular gear 6, wherein non-garden, first road eccentric gear 8 is corresponding with two-opening type reduction gearing 2,3 and engine belt pulley 1 by two-way engaged clutch 13, non-garden, the 3rd road eccentric gear 6 is fitted with crank 5, be connected with connecting rod 4 on the crank 5, connecting rod 4 external rocking arms.
The above-mentioned lever assistor that is used for trepan, the center of non-garden, described first road eccentric gear 8, non-garden, second road eccentric gear 7, non-garden, eccentric gear 6 three roads, non-garden, the 3rd road eccentric gear axle point-blank, and non-garden, three roads eccentric gear is identical, the modulus unanimity.
The technological progress that the utility model is obtained is: the utility model adopts the non-circular eccentric gear in three roads to be meshing with each other and realizes afterburning structure, and the hoisting velocity of well awl is slowed down, and has prolonged the working life of parts; The impact velocity that the sinking speed of awl is promptly bored is accelerated, and improved the vertical impact power of awl to ground greatly, but the number of times of its impact is constant, thereby has shortened the time of whole work, has improved operating efficiency.
Description of drawings
Fig. 1 is the structural representation that the utility model is used for the lever assistor of trepan;
Among Fig. 1,1-engine belt pulley, 2-open type reduction gearing, 3-open type reduction gearing, 4-connecting rod, 5-crank, the non-circular eccentric gear in 6-the 3rd road, the non-circular eccentric gear in 7-second road, the non-circular eccentric gear in 8-first road, the 9-winding gear, the 10-winding gear, 11-hoist engine cylinder, 12-hoist engine braked wheel, the two-way engaged clutch of 13-, the 14-frame.
The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples.
As shown in Figure 1, the utility model is based on a non-garden eccentric gear group, this non-garden eccentric gear group is made of the non-round eccentric gear 8 in intermeshing successively first road, three roads, non-garden, second road eccentric gear 7, the 3rd road non-circular gear 6, the center of non-garden, first road eccentric gear 8, non-garden, second road eccentric gear 7, non-garden, eccentric gear 6 three roads, non-garden, the 3rd road eccentric gear axle point-blank, and non-garden, three roads eccentric gear is identical, the modulus unanimity; Wherein non-garden, first road eccentric gear 8 is corresponding with two-opening type reduction gearing 2,3 and engine belt pulley 1 by two-way engaged clutch 13, and non-garden, the 3rd road eccentric gear 6 is fitted with crank 5, is connected with connecting rod 4 on the crank 5, connecting rod 4 external rocking arms;
Its operating principle is as follows: by engine through a belt pulley transmission and an opposite opened reduction gearing transmission, to move through two-way engaged clutch again and pass to non-garden, first road eccentric gear of non-garden eccentric gear group with power, the long radius engagement of the non-garden of the small radius and second road eccentric gear of non-garden, first road eccentric gear, at this moment play partial reinforcing, in reinforcing, crank drives rocking arm by connecting rod and by wire rope awl is mentioned, when crank turns over after bottom dead center, because the variable-speed motion of non-garden eccentric gear and the gravity of awl itself, awl descends fast, finishes a working cycles.In addition, this device can also be applied to bar cropper etc. mechanically.
Claims (2)
1, the lever assistor that is used for trepan, it is characterized in that: it is based on a non-garden eccentric gear group, this non-garden eccentric gear group is by the three roads non-round eccentric gears in intermeshing successively first road (8), non-garden, second road eccentric gear (7), the non-round eccentric gear in the 3rd road (6) constitutes, wherein non-garden, first road eccentric gear (8) is by two-way engaged clutch (13) and two-opening type reduction gearing (2), (3) and engine belt pulley (1) corresponding, non-garden, the 3rd road eccentric gear (6) is fitted with crank (5), be connected with connecting rod (4) on the crank (5), the external rocking arm of connecting rod (4).
