Abstract
The utility model provides a novel opening mechanism, composed of an axis, a spring, a steel tube, a bit cover, a barrel, two connecting plates, a bolt, a nut, a gasket, a support plate, a hook, a baffle plate, a basal hook, a mechanism at the bottom of the barrel, a rectangular steel tube, a drilling rod and a cylindrical pin. The steel tube is welded on the bit cover, and the support plate is welded on the barrel; the upper part of the axis is connected with the axis through the spring by passing through the hole of the bit cover, and the lower part of the axis is connected with the two connecting plates by connecting pieces. The lower parts of the two connecting plates are connected with the upper part of the hook by the connecting piece, and the middle part of the hook is connected with the support plate by the connecting piece. The novel opening mechanism has the advantages of high speed, high efficiency, convenient operation, simple structure, convenient maintenance, etc. during opening.
Description
When technical field the utility model relates to the work of the used drill bit of a kind of rotary drilling rig, be used for the opening mechanism of drill bit, when the drill bit that is adapted to rotary drilling rig especially repeatedly often uses.
Background technology is present, and the form of rotary drilling rig drill bit has several, when the work of rotary drilling rig, a kind of opening mechanism of opening soon will be arranged on the drill bit that it was equipped with, and can make things convenient for the loading and unloading of sand.It is connectors such as the axle composition of boring with spring, leaf chain, spring fixed seat, chain holder, band that the opening mechanism of the used drill bit of existing rotary drilling rig adopts, drill bit is when work, the drill bit bottom takes place often to be not closed completely, cause the sand in the drill bit to drain back in the hole, not only reduce drilling efficiency, but also influenced the use of the normal efficiency of cleannes at the bottom of the hole and machine.
The summary of the invention the purpose of this utility model provides a kind of easy to loading and unloading, opens easily safe and reliable a kind of novel opening mechanism.
The purpose of this utility model is achieved in that this novel opening mechanism is by axle, spring, steel pipe, the drill bit lid, cylindrical shell, junction plate, bolt, nut, packing ring, base plate, hook, plate washer, the bottom crotch, cylindrical shell bottom mechanism, rectangular steel tube, drilling rod, straight pin is formed, steel pipe is welded on drill bit and covers, base plate is welded on the cylindrical shell, the hole of drill bit lid is passed on the top of axle earlier, link with spring and axle, the bottom of axle links with connector and two junction plates, the bottom of two junction plates and the top of hook link with connector, and the middle part of hook links with connector and base plate.
The cross sectional shape of described axle is an open circles, and bottom perforate and junction plate, connector link.
The end of described spring is also not tight, polishes.
Described base plate cross sectional shape is a rectangle, and top drilling links with axle.
The cross sectional shape of described hook is the J hook-type, the top perforate of hook links with axle, connector, the middle part perforate and the connector of hook link, the bottom of hook when drill bit creeps into and crotch mating face, bottom link, the bottom of hook when drill bit does not creep into and the bottom crotch throw off.
The cross sectional shape of described bottom crotch is a F shape, the top of bottom crotch when drill bit creeps into and the lower engagement face of hook link the welding of the bottom of bottom crotch and cylindrical shell bottom mechanism.
Because having adopted steel pipe to be welded on drill bit covers, base plate is welded on the cylindrical shell, the hole of drill bit lid is passed on the top of axle earlier, link with spring and axle, the bottom of axle links with connector and two junction plates, and the bottom of two junction plates and the top of hook link with connector, and the middle part of hook links with connector and base plate, the utility model is installed with maintenance very convenient, and can repeatedly often use.
Be described further below in conjunction with drawings and Examples.
Description of drawings Fig. 1 is a section of structure of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
Among the figure: 1. spool; 2. spring; 3. steel pipe; 4. drill bit covers; 5. cylindrical shell; 6. junction plate; 7. bolt; 8. nut; 9. packing ring; 10. base plate; 11. hook; 12. plate washer; 13. bottom crotch; 14. cylindrical shell bottom mechanism; 15. rectangular steel tube; 16. drilling rod; 17. straight pin; Gland 18
Specific embodiment steel pipe (3) is welded on drill bit lid (4), fix spring (2), base plate (10) is welded on cylindrical shell (5), after the hole and spring (2) of drill bit lid (4) passed on the top of axle (1), the bottom of axle (1) bolt (7), nut (8), packing ring (9) links with two junction plates (6), the top of the bottom of two junction plates (6) and hook (11) bolt (7), nut (8), packing ring (9) links, the middle part of hook (11) bolt (7), nut (8), packing ring (9) links with base plate (10), after regulating the contact surface of bottom crotch (13) and hook (11), again plate washer (12) is welded on the hook (11),, install very convenient like this.By above installation, finish present embodiment.
The course of work of the present utility model is: steel pipe (3) is welded on drill bit lid (4), fixing spring (2), base plate (10) is welded on the cylindrical shell (15), the top of axle (1) is placed in the hole and spring (9) of drill bit lid (4), the bottom of axle (1) and the top of two junction plates (6) link with connector, the top of the bottom of two junction plates (6) and hook (11) links with connector, the middle part of hook (11) links with the base plate (10) on connector and the cylindrical shell (5), drilling rod (16) links by the rectangular steel tube (15) of straight pin (17) with drill bit, when drill bit rotates in construction, whole opening mechanism seals, after drill bit is filled sand, with gland (18) impacting shaft (1), cylindrical shell bottom mechanism (14) and hook (11) are thrown off, sand in the drill bit is discharged at the outside in hole, thereby finishes the course of work of novel opening mechanism.
