The sliding mounting plate 322 set.And mounting plate floor is connected between sliding support plate 321 and sliding 322 lateral wall of mounting plate
323, to reinforce the structure of sliding component 32.The both ends of mounting plate 33 are respectively corresponded afterwards connect with two sliding support plates 321.It is sliding
The bottom wall for moving mounting plate 322 forms the 4th sliding slot.
Actuator 30 can use Driven by Hydraulic Cylinder part, and the front end of the piston rod of Driven by Hydraulic Cylinder part and rear mounting plate 33 connect
It connects, the hydraulic cylinder of Driven by Hydraulic Cylinder part is fixed on rock-core borer.Sliding mounting plate 322 can be slided by the 4th of its bottom
Slot is adapted to the track on rock-core borer and is slidably connected, and sliding mounting plate 322 is enable to move horizontally along track.
The present invention starts before clamping unloading work, the piston rod of Driven by Hydraulic Cylinder part stretches out drive after mounting plate 33 to Forward
It is dynamic, to drive rock-core borer clamping unloading device to move forward close to the aperture that drilling rod is worn and be located at and be capable of holding drill pipe
Position；Rock-core borer clamps unloading device and completes after clamping unloading work, and the piston rod withdrawal of Driven by Hydraulic Cylinder part is pacified after driving
Loading board 33 moves backward, to drive rock-core borer clamping unloading device to be moved rearwardly away from the aperture that drilling rod is worn, to mention
The utilization rate in high aperture space.
Optionally embodiment, lower clamping part 4 include lower actuator 41, lower clamping moving member 42, lower grip slipper group
Part 43 and two symmetrically arranged lower clamping pieces 44.The both ends of lower actuator 41 respectively correspond and lower clamping moving member 42 and lower folder
The connection of holder assembly 43 is held, to drive lower clamping moving member 42 to be moved forward and backward along lower clamping holder assembly 43.Two lower clamping pieces 44 with
Lower clamping moving member 42 is moved forward and backward and separate, close holding drill pipe direction is slidably embedded in lower clamping moving member 42 and lower folder
It holds in holder assembly 43.Lower clamping holder assembly 43 is installed on mounting base 3.
Specifically, as shown in Figures 1 to 4, lower clamping part 4 is symmetrically arranged in mounting base 3 with upper clamping part 1, lower clamping
The structure in portion 4 is identical as the structure of upper clamping part 1, and is bilateral symmetry, and has described in the above embodiments clear
Chu, therefore make a brief description at this.
Lower clamping moving member 42 includes lower moving member 421 and lower guide part 422.Lower moving member 421 connects with lower guide part 422
It connects.It is clamped in holder assembly 43 under the insertion capable of sliding back and forth of upper guide part 122.One end of lower actuator 41 is to drive lower moving member
421 back-and-forth motions are connect with lower moving member 421.
Lower clamping holder assembly 43 includes lower grip slipper 431 and lower mounting flange 432.The lower part of lower grip slipper 431 and lower peace
Fill the top connection of flange 432.Lower clamping piece 44 is slidably embedded in lower clamping moving member 42 and lower grip slipper 431, lower drive
The other end of moving part 41 is connect with lower grip slipper 431.Lower mounting flange 432 is rotatably installed on unloading portion 2.
Lower clamping piece 44 includes lower clamping guide holder 441 and the lower slips 442 for holding drill pipe.Lower clamping moving member 42
On lower limit pin 4211 is installed.Lower clamping guide holder 441 is connect with lower slips 442, and the slidably lower clamping movement of insertion
In part 42 and lower clamping holder assembly 43.The upper end of lower limit pin 4211 is slidingly nested in lower clamping guide holder 441 and is formed by tiltedly
Into the lower guide groove 4411 of setting.
Lower clamping holder assembly 43 can be connected by screw bolts with mounting base 3.
In holding drill pipe, lower actuator 41 and upper actuator 11 are synchronous respectively or are corresponding in turn to that driving is lower to clamp moving member
42 and upper clamping moving member 12 moved backward respectively along lower clamping holder assembly 43 and upper clamping holder assembly 13, to make to press from both sides under two
Gripping member 44 and two upper clamping pieces 14 are protruding, to move close to the translation of holding drill pipe direction to drill-rod clamping to center.
When the present invention completes work, upper actuator 11 and lower actuator 41 are synchronous respectively or are corresponding in turn to drive and clamp
Moving member 12 and lower clamping moving member 42 are moved forward along upper clamping holder assembly 13 and lower clamping holder assembly 43 respectively, to make two
A upper clamping piece 14 and two lower clamping pieces 44 are withdrawn, with mobile far from center, far from the translation of holding drill pipe direction to drilling rod pine
It opens.
Further, lower clamping 42 inner wall of moving member of close fitting fitting under drilling rod gravity is formed on lower clamping piece 44
Lower wedge surface 4412.
Specifically, as shown in Figure 5 and Figure 6, in order to guarantee lower clamping piece 44, that is, the clamping force of lower slips 442, especially
The clamping force of lower slips 442 when being hydraulic system exception when drill rod abrasion or lower actuator 41 use Driven by Hydraulic Cylinder part.Under
Clamping piece 44 and lower clamping moving member 42, that is, clamp guide holder 441 under two and respectively correspond the left and right with lower moving member 421
Two sides adaptation fitting inner wall is formed as wedge shape.It is formed on i.e. lower clamping guide holder 441 and is adapted under fitting with lower moving member 421
Wedge surface 4412.When the lower slips 442 of two sides clamp drilling rod, the left and right sides inner wall of lower moving member 421 is respectively corresponded and two
The corresponding lower wedge surface 4412 of lower clamping guide holder 441 fits closely.The self gravity of drilling rod is pressed on lower slips 442, so that under
Slips 442 has the tendency that moving downward, so that lower clamping guide holder 441 is driven to fit closely with lower moving member 421, downward weight
Power fits closely more greatly tighter.The upper thickness of lower wedge surface 4412 is smaller than lower part thickness, is made by the self gravity of drilling rod
Lower moving member 421 can play support and guiding role to lower slips 442, guarantee lower slips 442 to the reliable retention of drilling rod.
The upper of 12 inner wall of moving member is clamped in close fitting fitting likewise, being formed under drilling rod gravity on upper clamping piece 14
Wedge surface 1412.Wedge surface 1412 is formed on namely upper clamping guide holder 142.Upper wedge surface 1412 and lower wedge surface 4412 are upper and lower
Symmetrical structure, it is all that upper clamping guide holder 142 can be made to fit closely under drilling rod gravity to move up that it is identical, which to do role,
Moving part 121, and can be fitted closely with the increase of drilling rod gravity it is tighter, thus make upper slips 142 clamp drilling rod.
