Description

Foot clamp for perforator {clamp for exploration drill}

The present invention relates to a foot clamp for a perforator, and more particularly to a footprint lamp for a perforator for clamping a rod for perforation.

Generally, perforator is a device for excavating the deep hole penetrating from the ground to the ground for drilling work, soil inspection, groundwater development, etc.

A conventional art of a perforator is disclosed in Korean Patent Registration No. 0624233. [0002] A conventional perforator includes a main body provided with a driving device such as an engine, a leader supported by the main body, a head portion sliding on the leader and generating lift or rotation force by a drive device of the main body, And a digging unit provided at the tip of the rod and lifted or rotated together with the rod to excavate the ground.

The excavation unit consists of a bit excavated by hitting the ground, and a hammer operated by hydraulic pressure to impart a striking force to the bit. The transmission of the hydraulic pressure to the excavation unit becomes possible by installing a separate hydraulic line in the rod. In such a perforator, the bit of the drilling unit is rotated or excavated to a certain depth by striking the ground. As the ground is excavated, the excavation unit and the rod enter the ground.

 The length of the rod is extended by connecting the rod with the depth of the excavation unit and the depth at which the rod is drawn into the ground.

On the other hand, a load clamp is provided on the end of the reader near the ground to support the rod to which the digging unit is connected. The process of joining the rods comprises the step of pulling into the ground with the drilling unit to separate the head from the rod gripped by the rod clamp and then coupling the new rod to the head and coupling it to the rod gripped by the rod clamp .

The conventional rod clamp configured as described above is inserted into the ground to grasp the rods connected to each other for the punching operation, so that part of the load of the rods is supported, and the separation of the rod from the rotation axis of the rod is held so that the rod is not rotated. Particularly, when the diameters of the rods provided with the hammer are changed by the perforation, the gripping is not easy and the jaws for grasping the rod are difficult to transfer, and relatively long time is required for gripping. When the deep hole is drilled, the diameter of the rod is relatively increased. In order to compensate the structural strength of the joint portion, the diameter of the rod is larger than that of the body portion. In order to grip the rod, The gripping force according to the diameter can not be made uniform. The conventional rod clamp has a problem that the gripping force is relatively weakened when the weight of the rod becomes heavy because the gripping force is acted upon by the operation force of the actuator.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a perforator capable of improving the gripping force by allowing a part of the gripping force of the rod for puncturing to act on its own weight, To provide a foot clamp.

In order to achieve the above object, a foot clamp for a perforator is provided so as to correspond to each other and includes a first inner inclined portion inclined inwardly, a first vertical portion extending vertically from the first inclined portion, A first guide block having a first guide portion made up of a first outside inclined portion extending outwardly,

A second inner inclined portion inclined inward, a second vertical portion extending vertically from the second inner inclined portion, and a second guide portion formed of a second outer inclined portion extending outward from the first vertical portion, A guide block,

A frame supporting the first and second guide blocks in parallel with each other,

A first movable jaw that moves along the first guide portion of the first guide brock,

A second movable jaw that moves along the second guide portion of the second guide block,

A first driving shaft provided on the first driving shaft to lift and move the first movable jaw along the first guide portion, A second ridge installed on the second drive shaft for raising and lowering the second movable jaw along the second guide portion,

A connection link connecting the first and second links to rotate the first and second links in the same mutually opposite directions, and a driving unit for rotating the first rotation axis at a predetermined angle.

The foot lamp according to the present invention can improve the gripping force by the weight of the rod for perforation and can enhance the gripping force of the rod for perforations having different diameters.
