Abstract
The utility model relates to an auxiliary hoister which is one of key components of a rock machining drill for ground engineering. The auxiliary hoister comprises a shaft, a wound roll and a sun gear, wherein the wound roll is positioned on the shaft by a shaft sleeve, a bearing and a gland bush, and the sun gear is installed on the shaft and is connected by a key. The utility model is characterized in that the auxiliary hoister also comprises a ratchet wheel plate, a planetary gear and a planetary rack; a pressing plate is installed on the ratchet wheel plate, and then, the ratchet wheel plate is fixed to the wound roll; the planetary gear is assembled on the planetary rack by a pin shaft. The utility model uses a planetary mechanism to enhance lifting power and to enable the structure thereof to be simplified and reliable; besides, the utility model uses a ratchet wheel device to lock the wound roll, and then, heavy can be hung in the air.
Description
Technical field
The utility model relates to the secondary winch of one of critical component of Geotechnical Engineering Drilling rig.
Background technology
The rotating disc type engineering driller is applicable to that priming concrete pile holes such as skyscraper, harbour, dam, bridge, foundation work creep into.As one of critical component of engineering driller, secondary winch is mainly used in the loading, unloading drilling tool and uses.The transmission of secondary winch employing friction disc in the prior art, the brake band structure is adopted in braking, owing to be that the manual machine lever is controlled, so its complicated operating process, pulling pin and step on, span of control limit of control is big, use is frequent, and labour intensity is big; Secondly, former friction-type structure winch hoisting capacity is less than normal, can not satisfy the requirement of modern construction.
The utility model content
The purpose of this utility model is at existing deficiency, proposes a kind of application planetary mechanism increasing hoisting force and to make designs simplification reliable, and uses the secondary winch of the engineering driller of escapement locking reel.
In order to realize above-mentioned utility model purpose, the secondary winch of a kind of engineering driller that the utility model proposes comprises axle, reel and sun gear, reel is positioned on the axle by axle sleeve, bearing and gland, sun gear is contained in axle and goes up by key connecting, and its innovative point is also to comprise ratchet plate, planetary wheel and pinion carrier; Pressing plate is housed on the ratchet plate and is fixed on the reel, planetary wheel is assemblied on the pinion carrier by bearing pin.
On reel of above-mentioned secondary winch of the present utility model the same side and the pinion carrier cylindrical mechanical hatching gate brake strap is housed respectively.
With respect to prior art, the utility model is at first used planetary mechanism principle design planetary system to increase hoisting force, makes designs simplification reliable, be convenient to improve assembly precision and easy to operate, next is to use escapement locking reel, and weight is suspended in the air, and site safety is protected.Secondary winch compact conformation of the present utility model, the assembly precision height, hoisting capacity increases by 50%, satisfies the user and can directly adopt it to promote drilling tool in use, saves non-cutting time 20%, and the site safety coefficient improves greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein: 1 is left axle head supporting; 2 is bolt; 3 is packing ring; 4 is reel; 5 is bearing pin; 6 is bearing; 7 is back-up ring; 8 is planetary wheel; 9 is the band-type brake brake strap; 10 is internally toothed annulus; 11 is screw; 12 is pinion carrier; 13 is baffle plate; 14 is bolt; 15 is lubricating cup; 16 is right axle head supporting; 17 is input media; 18 is bolt; 19 is packing ring; 20 is gland; 21 is axle sleeve; 22 is bearing; 23 is sun gear; 24 is key; 25 is bearing; 26 is oil sealing; 27 is bearing; 28 is axle sleeve; 29 is axle; 30 is the ratchet plate; 31 is pressing plate; 32 is packing ring; 33 is bolt.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Be the secondary winch that the utility model one preferred embodiment is proposed as shown in Figure 1, right-hand member at axle 29 is equipped with input media 17, both sides are equipped with left axle head supporting 1 and right axle head supporting 16 respectively, axle 29 shoulders are equipped with bearing 27 and axle sleeve 28 on reel 4, left end gland and axle sleeve 28 are fixing with reel 4 by bolt 2 and packing ring 3, pressing plate 31 is housed to compress steel rope on the ratchet plate 30, ratchet plate 30 is fixing by bolt 33 and packing ring 32 with reel 4, axle 29 is equipped with bearing 22 and bearing 25 with pinion carrier 12 at shaft shoulder place, pinion carrier 12 is the two fulcrum pinion carriers of protruding formula, gland 20, axle sleeve 21 is fixing with pinion carrier 12 by bolt 18 and packing ring 19.Sun gear 23 is contained on the axle 29 and is connected by key 24, planetary wheel 8, bearing 6 and back-up ring 7 are assemblied on the pinion carrier 12 and by baffle plate 13 and bolt 14 by bearing pin 5 and fix, lubricating cup 15 is housed on the bearing pin 5, internally toothed annulus 10 and reel 4 close-fittings and fixing by screw 11 are equipped with mechanical hatching gate brake strap 9 respectively on reel 4 and pinion carrier 12 cylindricals.
Below in conjunction with description of drawings course of action of the present utility model.
As shown in Figure 1, when pinion carrier 12 glancing impacts, planetary wheel 8 is fixing, and sun gear 23 makes reel 4 work with planetary wheel 8 engagements and drive internally toothed annulus 10.When reel 4 glancing impacts, planetary wheel 8 moves around sun gear 23 and internally toothed annulus 10, and by the aerial weight of ratchet plate 30 lockings, plays safety effect.Realize secondary elevator lifting, transfer and brake all and realize by mechanical hatching gate braking planetary mechanism and reel.
