Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention.

The invention will now be further described with reference to the following examples and drawings:

the utility model provides a mediation device of knapsack rig rock core pipe, includes logical pole 1 and support 2, and 1 one end of logical pole sets up top 11, and 2 upper ends of support set up stop device, and stop device is used for restricting the removal of rock core pipe 5. When the rock core pipe 5 is blocked and needs to be dredged, the rock core pipe 5 is erected on the limiting device, the limiting device limits further movement of the rock core pipe 5, the supporting and limiting effects are achieved, and the through rod 1 is used for dredging the rock core pipe 5.

The limiting device comprises a circular tube 4, and the two sides of the circular tube 4 are both hinged with the support 2. When a rock core needs to be taken, the rock core pipe 5 is inserted into the circular pipe 4, the circular pipe 4 limits the movement of the rock core pipe 5, and the through rod 1 is used for dredging the rock core pipe 5. The round pipe 4 can rotate on the bracket 2 through the hinged arrangement, and the lifting height of the round pipe 4 can be adjusted randomly during use.

The circular tube 4 is provided with an internal thread. Because both ends of the core barrel 5 are provided with external threads, when the dredging device is used, the circular tube 4 can be in threaded connection with the core barrel 5, and the function of limiting the movement of the core barrel 5 is achieved.

The round pipe 4 comprises a first round pipe 41 and a second round pipe 42, the first round pipe 41 is fixedly connected with the second round pipe 42, the inner diameter of the first round pipe 41 is matched with the outer diameter of the core barrel 5, and the inner diameter of the second round pipe 42 is matched with the inner diameter of the core barrel 5. When the support is used, the support 2 is placed on the ground, the core barrel 5 to be dredged is inserted into the circular tube 4, and the second circular tube 42 can block the core barrel 5 because the inner diameter of the second circular tube 42 is consistent with that of the core barrel 5, so that the support has the function of supporting and preventing the core barrel 5 from moving when the core barrel is dredged. When the through rod 1 is used for dredging the core pipe 5 of the backpack drilling machine, the top 11 is used as a top and impacts the core in the core pipe 5 to separate the core from the core pipe 5.

The lower end of the support 2 is provided with at least one supporting leg 3, the lower end of the supporting leg 3 is a pointed end, and the supporting leg 3 is provided with a supporting flat plate 31. When in use, the pointed supporting legs 3 can be inserted into the ground, so that higher stability is provided, meanwhile, the supporting plate 31 is fixedly connected between the supporting legs 3, when the supporting legs 3 are inserted into the bottom surface, the supporting plate 31 can be attached to the ground, and the supporting plate 31 has a large area, so that the stability is better. Meanwhile, the user may step on the support plate 31 with his foot when using the device.

The surface of the through rod 1 is provided with antiskid patterns 14. When the core barrel 5 is dredged, pushing and pulling are required, and at this time, the hand slip may occur, and the anti-slip pattern 14 is provided, so that the occurrence of the situation can be greatly reduced.

The other end of the through rod 1 is provided with an end head 12, the middle part of the through rod 1 is provided with a sheath 13, and the sheath 13 is made of rubber. The end 12 is provided to prevent the through rod 1 from being removed by sliding when pulling the core barrel 5. The sheath 13 is provided to prevent the palm of the hand from hitting the core barrel 5 and injuring the palm of the hand when the hand slips or the through rod 1 passes through the core barrel 5 during the pushing operation.

The maximum dimension of the plug 11 matches the inside diameter of the core barrel 5. The plug 11 is circular, triangular, quadrangular, pentagonal, hexagonal or other polygonal, or irregular. Regardless of the shape of the tip 11, its maximum dimension should be slightly less than the inside diameter of the core barrel 5 of the backpack drill so that it can freely impact back and forth within the core barrel 5.

The through rod 1 is made of metal. When the core barrel 5 is dredged, the through rod 1 needs to impact the core in the core barrel 5 back and forth, which requires that the body of the through rod 1 has certain strength and can bear the back and forth impact.

The device of the utility model solves the difficult problems of coring and blocking and dredging of the core barrel 5 of the backpack drilling machine, not only improves the working efficiency, but also effectively reduces the safety risk; meanwhile, the device has low cost and can be repeatedly used for a long time.

The utility model discloses a working process as follows:

in the working process of the backpack drilling machine, when the rock core in the rock core pipe 5 needs to be taken out and the rock core pipe 5 is blocked, the rock core pipe 5 and the drill bit are dismounted. Place support 2 subaerial, landing leg 3 inserts in the ground, until when ground contact support flat plate 31, just install support 2, the core barrel 5 that will dredge inserts the pipe 4 on the support 2, because the internal diameter of second pipe 42 is unanimous with the internal diameter of core barrel 5, so the core barrel 5 can be blockked to second pipe 42, has the effect of support, and core barrel 5 takes place the motion when preventing to dredge. One end of the top 11 of the through rod 1 is inserted into the core barrel 5, the support flat plate 31 is stepped by feet, and then the through rod 1 is pushed and pulled forcibly until the core is taken out or the core barrel 5 is dredged, and the operation can be continued after the completion.

While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
