Abstract
The utility model discloses a disk spring damping power head for a rotary drilling jig, the disk spring damping power head includes a pressure disk, a reduction box, a damping device, a protective frame, a sleeve, a motor, a carriage, a disk spring set, a guide sleeve, a pressure plate, and a flange plate, and the disk spring damping power head is characterized in that the disk spring set is arranged above the guide sleeve, the pressure plate is arranged at the top surface of the disk spring set, the flange plate is arranged above the pressure plate, the sleeve is arranged under the guide sleeve, and the pressure disk is arranged under the sleeve. The disk spring damping power head adopts the disk spring to perform damping, thus, the structure is simplified, the height of the power head is reduced, good damping effects are realized and the maintenance and replacement are easier.
Description
Technical field
The utility model relates to a kind of unit head, particularly relates to a kind of dish spring damping unit head of rotary drilling rig.
Background technology
At present, China's rotary drilling rig extensive use in pile foundation construction.Unit head is the key working part of rotary drilling rig, and unit head shock-damping structure commonly used has two kinds, and a kind of is to adopt the damping of spiral dish spring, and another kind is that unit head top adds Rubber shock-absorbing pad.Use the back to find that with the damping of spiral dish spring, though damping effect is fine, the height of unit head is higher, this has brought inconvenience for the installation of drilling rod; Though and meet the demands on the unit head height of application of rubber pad damping, the Rubber shock-absorbing pad damping effect is bad, durability is also very poor, usually smashed, thereby otherwise the periodic replacement, influence drilling machine construction efficient.
Summary of the invention
It is a kind of with dish spring replacement Rubber shock-absorbing pad or cylinder dish spring that the purpose of the utility model is to provide, and reasonably selects the compound mode of dish spring and the quantity of dish spring for use.Dish spring rigidity is big, and the buffering damping capaicty is strong, can bear big load with little distortion, suitable little place, between centers space, simple in structure, easy to use, the dish spring damping unit head of reliable installation.
The technical solution of the utility model is such: a kind of dish spring damping unit head; Comprise platen, reduction box, damping device, protect frame, sleeve, motor and balladeur train, dish spring group, guide pin bushing, pressing plate and flanged plate is characterized in that above the guide pin bushing it being dish spring group; Dish spring group end face is a pressing plate; Being flanged plate above the pressing plate, is sleeve below the guide pin bushing, is platen below the sleeve.
Dish spring group has an above dish spring combination, and the flanged plate above the pressing plate is used bolt tightening.
Guide pin bushing is connected with sleeve through hexagon socket head cap screw, and dish spring group is built in the guide pin bushing, and pressing plate is pressed on the dish spring group, and flanged plate is connected with guide pin bushing through hex bolts.
The utility model has the advantages that rigidity is big with the replacement of dish spring present rubber or spiral decompression, the shock-absorbing buffer capacity is strong; Be fit to the little occasion of axial space and can want type according to reality; Rational constituency is with the compound mode of dish spring and the quantity of dish spring, and is simple in structure, reasonable in design; Easy to install, compliance is strong.
Description of drawings
It is such that the structure of the utility model constitutes:
Fig. 1 is the utility model overall structure outside drawing.
Fig. 2 is the utility model structure sectional view.
Fig. 3 is that the utility model dish spring composite member is installed enlarged drawing.
Fig. 4-Fig. 8 is the utility model dish spring combining form sketch map, and wherein, Fig. 4 is superimposed combination dish spring, and Fig. 5 is the folded spring of involutory combination, and Fig. 6 is a composite combined dish spring, and Fig. 7 is the involutory combination dish spring of different-thickness, and Fig. 8 is the composite combined dish spring of different lamination layer numbers.
Among Fig. 1～Fig. 8, platen (1), reduction box (2), balladeur train (3), damping device (4), motor (5), protect frame (6), sleeve (7) | guide pin bushing (8), dish spring group (9) pressing plate (10), flanged plate (11).
The specific embodiment
The most preferred embodiment of the utility model is such, with reference to accompanying drawing, adopts the damping of dish spring, the mounting means of dish spring.Like Fig. 2, shown in Figure 3.Guide pin bushing (8) is connected with sleeve (7) through hexagon socket head cap screw; Dish spring group (9) is built in the guide pin bushing (8); Dish spring group (9) is chosen by the GB of butterfly spring with the gap of guide pin bushing (8), and pressing plate (10) is pressed on the dish spring group (9), and flanged plate (11) is connected with guide pin bushing (2) through hex bolts.The compound mode of dish spring group (9) and dish spring specification are decided according to concrete load and bulk.When drilling rod drops, with pressing plate (10) collision, and then compact disc spring group (9), thereby the speed that drops of the drilling rod that slows down stops drilling rod impact dynamic head.
Claims (3)
1. dish spring damping unit head; Comprise platen, reduction box, damping device, protect frame, sleeve, motor and balladeur train, dish spring group, guide pin bushing, pressing plate and flanged plate is characterized in that above the guide pin bushing (8) it being dish spring group (9); Dish spring group (9) end face is pressing plate (10); Being flanged plate (11) above the pressing plate (10), is sleeve (7) below the guide pin bushing (8), is platen (1) below the sleeve (7).
2. according to the described dish spring of claim 1 damping unit head, it is characterized in that dish spring group (9) has an above spring assembly, the flanged plate (11) above the pressing plate (10) is used bolt tightening.
3. according to the described dish spring of claim 1 damping unit head; It is characterized in that guide pin bushing (8) is connected with sleeve (7) through hexagon socket head cap screw; Dish spring group (9) is built in the guide pin bushing (8), and pressing plate (10) is pressed on the dish spring group (9), and flanged plate (11) is connected with guide pin bushing (8) through hex bolts.
