Abstract
The utility model discloses a kind of unit head locking device of rock-core borer, the first side of power is provided with axis of rotation, and axis of rotation overcoat has the interior eccentric adjusting sleeve with handle, and interior eccentric adjusting sleeve overcoat has the sleeve pipe with connecting rod; On the sliding sleeve of rock-core borer, establish U-shaped mouthful of clamp, the connecting rod other end of sleeve pipe can be connected with U-shaped mouthful of clamp clamping.The connecting rod other end of sleeve pipe is provided with adjusting nut, and connecting rod can be connected with U-shaped mouthful of clamp clamping by adjusting nut.Unit head locking device of the present utility model, can be simple and quick unit head be locked and unclamps upset, effectively increases work efficiency.
Description
Technical field
The utility model belongs to drilling equipment accessory fastening devices, is specifically related to a kind of unit head locking device of rock-core borer.
Background technology
The work of rock-core borer is mainly divided into boring and two steps of coring, during boring, by hydraulic cylinder, drive the unit head being fixed on sliding sleeve to slide, and by the bit bore on unit head, after boring finishes, unit head need to be overturn, by hoist engine, the basket of coring be sent in the hole of having bored to coring.Therefore, unit head need to time be completely fixed in boring, realizes upset during coring, for the device of coring gives way.The first side of existing power is connected with sliding sleeve bearing pin, and opposite side adopts the fixing mode of full bolt, during upset, need to successively many bolts be unclamped, and realizes upset.Such fixed form, dismounting and installation are all inconvenient, and waste time and energy.
Utility model content
The purpose of this utility model is: for the unit head of the rock-core borer inconvenient problem of overturning, provide a kind of unit head locking device of rock-core borer, can realize the quick upset of unit head and fixing.
To achieve these goals, the technical solution adopted in the utility model is:
A unit head locking device for rock-core borer, the first side of power is provided with axis of rotation, and axis of rotation overcoat has the interior eccentric adjusting sleeve with handle, and interior eccentric adjusting sleeve overcoat has the sleeve pipe with connecting rod; On the sliding sleeve of rock-core borer, establish U-shaped mouthful of clamp, the connecting rod other end of sleeve pipe can be connected with U-shaped mouthful of clamp clamping.
Preferably, the connecting rod other end of sleeve pipe is provided with adjusting nut, and connecting rod can be connected with U-shaped mouthful of clamp clamping by adjusting nut.
Preferably, the eccentric throw of interior eccentric adjusting sleeve is 1.3-1.7mm.
Owing to having adopted technique scheme, the beneficial effects of the utility model are:
The unit head locking device of a kind of rock-core borer of the present utility model, between the first side of power and the sliding sleeve of rock-core borer, adopt the buckle-type locking mechanism of axis of rotation, interior eccentric adjusting sleeve, sleeve pipe, connecting rod and U-shaped mouthful of clamp composition to be connected and fixed, in the time of fixedly, only connecting rod need be snapped in to U-shaped mouthful of clamp, then the handle on interior eccentric adjusting sleeve is pressed downwards, can be fixed; During upset, only need upwards stir handle, can unclamp retaining mechanism, then unit head be overturn; Fixing and the upset of unit head can both complete fast, time saving and energy saving, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is front view of the present utility model.
Fig. 3 is the A-A sectional view of Fig. 2.
Mark in figure: 1-sliding sleeve, 2-unit head, 3-axis of rotation, 4-sleeve pipe, eccentric adjusting sleeve in 5-, 6-connecting rod, 7-handle, 8-adjusting nut, 9-U type mouth clamp, 10-bearing pin.
The specific embodiment
With reference to Fig. 1-3, unit head 2 locking devices of a kind of rock-core borer of the utility model, unit head 2 one sides are connected by bearing pin 10 turnably with the sliding sleeve 1 of rock-core borer.The opposite side of unit head 2 is provided with axis of rotation 3, and axis of rotation 3 overcoats have the interior eccentric adjusting sleeve 5 with handle 7, and interior eccentric adjusting sleeve 5 overcoats have the sleeve pipe 4 with connecting rod 6.On the sliding sleeve 1 of rock-core borer, establish U-shaped mouthful of clamp 9, connecting rod 6 other ends of sleeve pipe 4 can be connected with U-shaped mouthful of clamp 9 clampings.The eccentric throw of interior eccentric adjusting sleeve 5 is 1.3-1.7mm, and the present embodiment is preferably 1.5mm.
During unit head 2 locking, only connecting rod 6 need be stuck on U-shaped mouthful of clamp 9, the handle of interior eccentric adjusting sleeve 57 is pressed downwards, interior eccentric adjusting sleeve 5 rotates around axis of rotation 3, a sidespin thicker in interior eccentric adjusting sleeve 5 forwards top position to, by sleeve pipe 4 jack-up upwards, thereby by connecting rod 6 tensions, realize being locked to unit head 2; In the time of need to overturning unit head 2, only the handle on interior eccentric bushing 7 upwards need be stirred, be made the sidespin that interior eccentric adjusting sleeve 5 is thicker forward lower position to, unclamp sleeve pipe 4, thereby unclamp connecting rod 6, at this moment turning unit head 2.
A kind of preferred version of the present utility model, connecting rod 6 other ends at sleeve pipe 4 are provided with adjusting nut 8, connecting rod 6 can be connected with U-shaped mouthful of clamp 9 clampings by adjusting nut 8, like this can be by regulating adjusting nut 8 to regulate the tension degree of connecting rod 6, prevent that connecting rod 6 from occurring loosening, the fixing not firm situation of unit head 2 occurs.
