Abstract
A straight-inclined double-purpose rotary table supporting device for a rock core drilling machine comprises two supporting pieces respectively arranged on two sides of a rotary table body of the rock core drilling machine. Each supporting piece comprises an adjusting pole. The upper end and the lower end of each adjusting pole are provided with inner threads, and the screwing direction of the inner threads of the upper end is opposite to the screwing direction of the inner threads of the lower end. The upper end of the adjusting pole is connected with one end of an upper connector through threads with adjustable strokes. An upper locking nut is arranged on the outer side of the joint of the adjusting pole and the upper connector. The other end of the upper connector is connected with an upper plain radial bearing which is connected through an upper round pin with an upper supporting base fixed on a side face of the rotary table body. The lower end of the adjusting pole is connected with one end of a lower connector through threads, and the outer side of the joint of the adjusting pole and the lower connector is provided with a lower locking nut. The other end of the lower connector is connected with a lower plain radial bearing which is connected with a lower supporting base fixed on a rack through a lower round pin. According to the straight-inclined double-purpose rotary table supporting device for the rock core drilling machine, overall rigidness of working parts of the rotary table body is improved, service life of the rotary table body is prolonged, and the hole direction is stable and easy to control.
Description
Technical field
The utility model relates to rock-core borer, particularly a kind of straight oblique dual-purpose rotary case bracing or strutting arrangement that is used for rock-core borer.
Background technology
In the drilling equipment of domestic and international market, rig kind series is various at present.Large-scale rock-core borer rotary case is bulky, and is the state that suspends and connects and to be contained on the transfer case, does not have other fixed support devices.The quality of rotary case own is bigger, trembles under the duty and rocks, and unbalance stress and volume are bigger; Performance is especially obvious when beating dark inclined hole; The collar that causes being connected with transfer case is easy to generate mechanical fatigue, and causes boring direction to depart from former target easily, is unfavorable for drilling construction.
The utility model content
Tremble and rock, be prone to produce mechanical fatigue and pore volume is prone to draw inclined to one side deficiency in order to overcome the existing rotary case course of work; The utility model provides a kind of straight oblique dual-purpose rotary case bracing or strutting arrangement that is used for rock-core borer; Rotary case working portion integral rigidity was improved when it made work, and it is safer to construct, and rotary case prolongs application life; Kong Xianggeng is stable, and is easy to control.
For solving the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of straight oblique dual-purpose rotary case bracing or strutting arrangement that is used for rock-core borer; It comprises two support members that are arranged at rock-core borer rotary case both sides respectively; Each support member comprises the adjusting rod of a hollow, and the upper/lower terminal of this adjusting rod is provided with the opposite internal thread of rotation direction; And the upper end of this adjusting rod is connected through the adjustable screw thread of stroke with an end of top connection; The outside of both junctions is provided with upper locking nut; The other end of this top connection links to each other with last plain radial bearing, and plain radial bearing is connected on the upper bracket that is fixed in the rotary case side on this through last straight pin; The lower end of this adjusting rod is connected through the adjustable screw thread of stroke with an end of lower contact; The outside of both junctions is provided with lower locking nut; The other end of this lower contact links to each other with following plain radial bearing, and this time plain radial bearing is connected on the undersetting that is fixed in frame through following straight pin.
Further being improved to of the utility model, the upper end of this adjusting rod is made as right-handed thread, and the lower end is made as left hand thread; Perhaps, the upper end of this adjusting rod can be made as left hand thread, and the lower end can be made as right-handed thread.
Compared with prior art; The beneficial effect that the utility model had is: the utility model is by the opposite internal thread of rotation direction of the upper/lower terminal setting of adjusting rod; When unclamping upper and lower locking nut, the screw-threaded engagement size through between turn adjusting rod ability flexible adjusting rod and the upper and lower joint reaches the requirement of regulating the effective active length of diagonal brace; Fixation through upper and lower locking nut simultaneously; Rotary case can be fixed and hole in the optional position in positive and negative 13 °, and can effectively reach with supporting role being connected of frame and rotary case through two support members and to improve rotary case part integral rigidity, prolongs rotary case application life; Make that construction is safer, and guarantee the more accurate and stable effect of boring direction.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the assembling sketch map of the utility model.
Among the figure: 1. adjusting rod, 2. top connection, 3. upper locking nut is 4. gone up plain radial bearing, 5. goes up straight pin; 6. upper bracket, 7. lower contact, 8. lower locking nut 9. descends plain radial bearing, 10. descends straight pin; 11. undersetting, 12. rotary cases, 13. support members, 14. frames.
The specific embodiment
Like Fig. 1 and shown in Figure 2; The straight oblique dual-purpose rotary case bracing or strutting arrangement that the utility model is used for rock-core borer comprises two support members 13 that are arranged at rock-core borer rotary case 12 both sides respectively; Each support member 13 comprises the adjusting rod 1 of a hollow, and the upper/lower terminal of this adjusting rod 1 is provided with the opposite internal thread of rotation direction.And the upper end of this adjusting rod 1 is connected through the adjustable screw thread of stroke with an end of top connection 2; The outside of both junctions is provided with upper locking nut 3; The other end of this top connection 2 links to each other with last plain radial bearing 4, and plain radial bearing 4 is connected on the upper bracket 6 that is fixed in rotary case 12 sides through last straight pin 5 on this.The lower end of this adjusting rod 1 is connected through the adjustable screw thread of stroke with an end of lower contact 7; The outside of both junctions is provided with lower locking nut 8; The other end of this lower contact 2 links to each other with following plain radial bearing 9, and this time plain radial bearing 9 is connected on the undersetting 11 that is fixed in frame 14 through following straight pin 10.
When beating upright opening; At first unclamp upper locking nut 3 or lower locking nut 8,, make effective active length of two support members 13 reach consistent through turn adjusting rod 1; Lock upper locking nut 3 or lower locking nut 8 again, can play effect fixing and supporting wheel body 12.
When beating inclined hole; At first unclamp upper locking nut 3 or lower locking nut 8; Through turn adjusting rod 1, effective active length of two support members 13 is shortened and elongation according to rotary case 12 required angles respectively, finally make rotary case 12 arrive at required special angle; Locking upper locking nut 3 or lower locking nut 8 can played the effect of playing well secured and supporting wheel body 12 under the inclined hole state.
