Abstract
The invention discloses a drill rod clamp. The drill rod clamp comprises a base (1), a U-shaped fixing block (2), a pressing plate (3), a sliding block (4), an eccentric wheel (5), a handle (6) and a wheel shaft (7). The U-shaped fixing block (2) is fixedly installed on the base (1). The sliding block (4) is arranged in a U-shaped groove of the U-shaped fixing block (2) and can horizontally slide along the U-shaped groove, and the face, facing the arc bottom of the U-shaped fixing block (2), of the sliding block (4) is in a C shape. The pressing plate (3) is arranged on the U-shaped fixing block (2), fixedly connected with the base (1) and used for limiting vertical moving of the sliding block (4). The wheel shaft (7) is erected at the open end of the U-shaped fixing block (2), and the eccentric wheel (5) and the handle (6) are arranged on the wheel shaft (7). The eccentric wheel (5) is in surface contact with the sliding block (4). The drill rod clamp is simple in structure, convenient to install and use, and capable of increasing clamping force on a drill rod and preventing slipping when the drill rod is detached to eradicate perils.
Description
Technical field
The present invention relates to a kind of drill rod grip device, belong to rig field.
Background technology
Need during rig punching, along with the continuous extension arm of the increase of drilling depth, to want a joint one to save land after punching completion and pull down drilling rod.Punch in vertical direction, when tearing drilling rod open, first have to the drilling rod clamping in boring, the most again that a part of drilling rod outside dismounting boring.For preventing drilling rod from gliding under self gravitation effect, prior art is to use oild chuck to carry out drilling rod clamping work, but it is as the needs of scientific research and engineering, the degree of depth of boring is more and more deeper, drilling rod constantly lengthens, weight even to reach several tons overweight, during mounting or dismounting drilling rod, drilling rod skidding in clamper often occur, meeting the most out of control causes major accident.
Summary of the invention
Present invention aim at providing a kind of drill pipe clamp, it is to avoid drilling rod skidding in clamper occurs during dismounting drilling rod.
For achieving the above object, one drill pipe clamp of the present invention, 1. a drill pipe clamp, it is characterised in that include pedestal (1), U-shaped fixed block (2), pressing plate (3), slide block (4), eccentric (5), handle (6) and wheel shaft (7)；The first through hole (11) is offered in pedestal (1) centre, and U fixed block (2) is fixedly mounted on pedestal (1)；Slide block (4) is arranged in the U-type groove of U-shaped fixed block (2), can slide along U-type groove level, is to form the second through hole (12) at the bottom of C-shaped, with the arc of U-shaped fixed block (2) towards the one side at the bottom of U-shaped fixed block (2) arc；Pressing plate (3) is arranged on U fixed block (2) above, fixes with pedestal (1) and is connected, and limits slide block (4) vertical direction and moves, is provided with third through-hole (13)；Described first through hole (11), the second through hole (12) and third through-hole (13) are concentric；Wheel shaft (7) is erected at the opening of U-shaped fixed block (2), eccentric (5) and handle (6) and is arranged on wheel shaft (7)；Eccentric (5) contacts with slide block (4) face.
Present configuration is simple, installs, easy to use, and the auxiliary device as oild chuck uses, can strengthen and drilling rod is added holding force, it is to avoid occur during dismounting drilling rod that skidding eliminates danger accident generation.
Accompanying drawing explanation
Fig. 1 is the front front view of the present invention；
Fig. 2 is the upward view of Fig. 1.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of drill pipe clamp, including pedestal 1, U-shaped fixed block 2, pressing plate 3, slide block 4, eccentric 5, handle 6 and wheel shaft 7；The first through hole 11 is offered in pedestal 1 centre；U fixed block 2 is fixedly mounted on pedestal 1；Slide block 4 is arranged in the U-type groove of U-shaped fixed block 2, can slide along U-type groove level, is C-shaped towards the one side at the bottom of U-shaped fixed block 2 arc, forms the second through hole 12 at the bottom of the arc of U-shaped fixed block 2；Pressing plate 3 is arranged on above U fixed block 2, fixes with pedestal 1 and is connected, limits slide block 4 vertical direction and move, be provided with third through-hole 13；Described first through hole the 11, second through hole 12 and third through-hole 13 are concentric；Wheel shaft 7 is erected at the opening of U-shaped fixed block 2, eccentric 5 and handle 6 and is arranged on wheel shaft 7；Eccentric 5 contacts with slide block 4.
During use, being fixed on by drill pipe clamp on the safe sleeve pipe in aperture, drilling rod is through the first through hole the 11, second through hole 12 and third through-hole 13 successively.During work, handle 7 band movable eccentric wheel 5 rotates, and makes slide 5 slide to direction level at the bottom of the arc of U-shaped fixed block 2, and the second through hole 12 reduces and holding drill pipe.Rotating backward handle 6, slide 5 unclamps under drilling rod effect automatically.
Present configuration is simple, installs, easy to use, and the auxiliary device as oild chuck uses, can strengthen and drilling rod is added holding force, it is to avoid occur during dismounting drilling rod that skidding eliminates danger accident generation.
Further, it is respectively provided with frictional layer in the inner side cambered surface of described U-shaped fixed block (2) and on the C-shaped face of slide block (4), coefficient of friction can be increased, improve skidproof effect.
Preferably, slide block (4) and pressing plate (3) are connected with pedestal (1) by bolt respectively, it is simple to dismounting.
