Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings and embodiments, and it is to be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 3: a drill stem pulling device comprises a tube pulling seat 1 and a tube pulling fork 2; the tube drawing fork 2 comprises a handle 21, fork rods 23 are arranged on two sides of one end of the handle 21, and a pressing part 27 is arranged on the other end of the handle; one end of the fork rod 23, which is far away from the handle 21, is provided with a mortise 22; the middle parts of the two fork rods 23 are connected through bolts 25, and a pressing sleeve 24 is sleeved on each bolt 25;
the tube drawing seat 1 comprises a tube drawing seat body 11, and clamping tenons 12 matched with the clamping tenon grooves 22 are arranged on two sides of the tube drawing seat body 11; and the tube drawing seat body 11 is also provided with a tube drawing groove 13 for installing the impact drill rod 3.
According to the invention, the pipe drawing seat 1 and the pipe drawing fork 2 are sleeved on the outer side of the impact drill rod 3 in a matching manner, so that when the impact drill rod 3 is drawn up, the top end of the impact drill rod 3 is in an open state, and a hose or a cable in the impact drill rod 3 can move at the top end of the impact drill rod 3 conveniently; and tube drawing seat 1 and tube drawing fork 2 all set up the side of strikeing drilling rod 3 can be divided into the multistage with the pull-out height degree of overlength and pull out, reduces the requirement to pulling out equipment, guarantees better pulling out effect.
By pressing the pressing part 27 downwards, the tube drawing fork 2 is driven to rotate around the tenon 12, and the clamping of the tube drawing groove 13 and the pressing sleeve 24 on the percussion drill rod 3 is completed.
The tube drawing fork 2 is driven to rotate around the tenon 12 by lifting the pressing part 27, and the tube drawing groove 13 and the pressing sleeve 24 are loosened on the percussion drill rod 3.
Further, the pressing sleeve 24 is provided with an arc-shaped recess 26 for fitting the percussion drill rod 3.
The contact area between the pressing sleeve 24 and the impact drill rod 3 can be increased through the arc surface depression 26, the friction force between the pressing sleeve 24 and the impact drill rod 3 is increased, a good pulling effect is guaranteed, and anti-skid grains are further arranged in the arc surface depression 26 in the specific implementation process.
Further, the tube drawing groove 13 is V-shaped in cross section.
The section of the tube drawing groove 13 is V-shaped, so that the contact surface between the tube drawing groove 13 and the impact drill rod 3 can be increased, the friction force between the tube drawing seat body 11 and the impact drill rod 3 is increased, and a better drawing effect is ensured.
Further, slips 131 are arranged on two side surfaces in the pipe drawing groove 13.
Through slips 131 better increase the frictional force between the tube drawing seat body 11 and the impact drill rod 3, better pulling effect is guaranteed.
Further, the mortise and tenon groove 22 is an inclined U-shaped groove.
The mortise slot 22 is a U-shaped slot, that is, the tube drawing seat 1 and the tube drawing fork 2 are convenient to disassemble, and the pulling device does not need to be sleeved from the top end of the impact drill rod 3 when being installed, so that the pulling device can be more conveniently assembled at a proper position; and the inclined U-shaped groove is adopted, so that the tube drawing seat 1 is not easy to fall off from the tube drawing fork 2 when the tube drawing seat 1 and the tube drawing fork 2 are assembled, and the tube drawing seat 1 can better drive the tube drawing fork 2 and the impact drill rod 3 to move upwards when the pulling device holds the impact drill rod 3, and a better pulling effect is ensured.
Further, one side of the pipe drawing seat body 11, which is far away from the impact drill rod 3, is connected with a lifting device.
The working principle of the invention is as follows:
the pipe drawing seat 1 is stopped at a proper position, so that the impact drill pipe 3 is positioned in a V-shaped space formed by slips 131; aligning the mortise 22 of the fork rod 23 with the tenon 12 of the pipe drawing seat body 11, and the impact drill rod 3 is positioned between the slips 131 and the pressing sleeve 24; aligning the cambered surface recess 26 on the pressing sleeve 24 with the outer surface of the percussion drill rod 3, and pressing the pressing part 27 of the handle 21;
the impact drill rod 3 is pushed to cling to the slips 131 through the cambered surface recess 26 on the pressing sleeve 24, and the slips 131 and the pressing sleeve 24 hold the impact drill rod 3 tightly; the tube drawing seat 1 is driven to move upwards through the lifting device, and the impact drill rod 3 is drawn upwards; after the impact drill rod 3 is pulled out for a certain distance, the handle 21 is lifted upwards, and then the impact drill rod 3 is loosened with the slips 131 and the pressing sleeve 24; at the moment, the pipe drawing seat 1 is moved downwards until the pipe drawing seat is at a proper position, the handle 21 is pressed downwards, the slip 131 and the pressing sleeve 24 tightly hold the impact drill pipe 3 again, the pipe drawing seat 1 is moved upwards, and the impact drill pipe 3 is drawn out upwards for a certain distance again; this is repeated until the percussion drill rod 3 is completely extracted.
