Abstract
The invention relates to a device for locking a drill rod based on the self-weight of the drill rod during drill rod clamping in the drilling construction process. Clamping plates are arranged on a base at intervals; a left rotating shaft and a right rotating shaft are rotated between the clamping plates; the left rotating shaft is fixedly provided with a left eccentric seat and a left cam; the right rotating shaft is fixedly provided with a right eccentric seat and a right cam; the left end of a connecting rod is hinged with a left crank; the right end of the connecting rod is hinged with a right crank; the rotating direction of the left rotating shaft is opposite to that of the right rotating shaft; a left slip and a right slip are arranged in a middle groove between the two clamping plates in a sliding way; the left cam is pressed against the left slip; and the right cam is pressed against the right slip. The device has a simple and compact structure, is safe and reliable, is easy to operate and convenient to maintain, is durable in use, and cannot damage a clamped drill rod; and the opening and closing actions of the slips can be realized on the basis of a stepping action and a releasing action of a pedal plate, so that a clamping function is realized after the drill rod is lifted and lowered on the basis of the self-weight.
Description
Technical field
The present invention relates to a kind of core drilling construction equipment, especially a kind of in the drilling operation process during clamping drilling rod by the device of drilling rod deadweight locking.
Background technology
In the core drilling work progress, need clamp at any time and unclamp drilling rod, and unclamp and the process that clamps is wanted rapidly, it is reliable that action is wanted, and will finish under the situation that does not increase the aperture operating personnel.
The working environment in aperture is very abominable, to the part of all mechanisms and structure all should with simple, practical and reliable be final design principles; Require to install and convenient disassembly, and for ease of maintenaince, be fit to open-air area and use.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of simple in structure, be fit to open-airly to use, easy to operate, deadweight type drill pipe clamp that security performance is good.
According to technical scheme provided by the invention, described deadweight type drill pipe clamp, be included in two grip blocks that internal and external partition is installed on the base, between two grip blocks, be rotatablely equipped with left rotary shaft and right spindle, left rotary shaft between two grip blocks fixedly has left eccentric mounting and left cam, right spindle between two grip blocks fixedly has right eccentric mounting and right cam, fixedly there is left crank outer end in left rotary shaft, fixedly there is right crank outer end at right spindle, the left end of connecting rod and left crank are hinged, the right-hand member of connecting rod and right crank are hinged, the direction of rotation of left rotary shaft and right spindle; Be slidingly fitted with left slips and right slips in the medial launder of two grip blocks, left cam and left slips offset, and right cam and right slips offset.
Between two grip blocks above the left slips, be plugged with left safety pin; Between two grip blocks above the right slips, be plugged with right safety pin.
The present invention is simple and compact for structure, and is safe and reliable, and processing ease is easy to maintenance, durable in use and can not cause damage to folded drilling rod; Slips is built in left and right sides eccentric mounting and the grip block, thus by under the foot pedal, decontrol that two actions can realize that slips opens, closed action realize drilling rod promote by deadweight and descend after the clamping function, applying on the suitable multiple drilling rod series.
Description of drawings
Fig. 1 is front view of the present invention.
Fig. 2 is vertical view of the present invention.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure, the present invention mainly is made of parts such as left eccentric mounting 1, left cam 2, left slips 3, connecting rod 4, grip block 5, right cam 6, left crank 7, right crank 8, right eccentric mounting 9, base 10, left rotary shaft 11, left safety pin 12, right spindle 13, right slips 14 and right safety pins 15.
This deadweight type drill pipe clamp, be included in two grip blocks 5 that internal and external partition is installed on the base 10, between two grip blocks 5, be rotatablely equipped with left rotary shaft 11 and right spindle 13, left rotary shaft 11 between two grip blocks 5 fixedly has left eccentric mounting 1 and left cam 2, right spindle 13 between two grip blocks 5 fixedly has right eccentric mounting 9 and right cam 6, in the outer end of left rotary shaft 11 left crank 7 is arranged fixedly, in the outer end of right spindle 13 right crank 8 is arranged fixedly, the left end of connecting rod 4 and left crank 7 are hinged, the right-hand member of connecting rod 4 and right crank 8 are hinged, the direction of rotation of left rotary shaft 11 and right spindle 13; Be slidingly fitted with left slips 3 and right slips 14 in the medial launder of two grip blocks 5, left cam 2 offsets with left slips 3, and right cam 6 offsets with right slips 14.
Between two grip blocks 5 above the left slips 3, be plugged with left safety pin 12; Between two grip blocks 5 above the right slips 14, be plugged with right safety pin 15.
Unclamp: when operating personnel depress the pedal of right eccentric mounting 9 with pin, right spindle 13 can clockwise rotate, by right crank 8 drivening rods 4, connecting rod 4 drives left rotary shaft 11 and rotates counterclockwise, final left cam 2 gets out of the way to the left, and right cam 6 gets out of the way to the right, thereby left slips 3 can be to the both sides branch with right slips 14, middle through hole increases, and drilling rod can be released.
When operating personnel's pin unclamps, be subjected to gravity effect, middle clamping partly can be fallen voluntarily, from and drilling rod clamped, finally namely: the foot-operated drilling rod that namely unclamps, pin is decontroled drilling rod and is clamped automatically again.
