The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is elaborated.
As shown in Figure 1, oil-well rig of the present invention is to comprise housing 1 with rat hole gripping mechanism structure; Housing 1 comprises the first half and the latter half; The centre position of the first half and the latter half has concentric through hole, adopts seam to be connected between the first half and the rat hole, and the latter half adopts bolt and rat hole to descend to save flange to be connected; Parallel with the one group separately ear seat in the left and right sides of the latter half connects (being ear seat I 3 and ear seat II 4); Ear seat I 3 is connected with the latter half through a plurality of turret head head eye bolts 8 respectively with ear seat II 4 fixes, and each turret head head eye bolt 8 all is equipped with spring washer 1, and two adjacent turret head head eye bolt 8 heads are connected through stainless steel wire 7; Play locking effect, reach the purpose of reliable insurance; Be respectively arranged with a hydraulic jack 6 in vertical cavity of ear seat I 3 and ear seat II 4; Hydraulic jack 6 piston rod ends of the left and right sides inwardly are connected with a slide block assembly 2 respectively; Piston rod end is provided with hexagon thin nut 9 and cottor pin 11; Play locking effect equally, reach the purpose of reliable insurance; Slide block 12 in two slide block assemblies 2 is provided with the pincers tooth 13 towards the axle center, and its clamping drilling tool scope is that 2-7/8 "～9-3/4 " (73～248mm), install and use when being used for different drilling tool clamping, and accommodation is than the obvious expansion of existing apparatus by correspondence.
Ear seat I 3 or ear seat II 4 are provided with nameplate assembly 5.
The form that the mode of being fixed and clamped of the pincers tooth 13 in the slide block assembly 2 adopts hexagon socket cap head screw 14 and spring washer 15 thereof to cooperate also can adopt other other form to compress, such as the crimper tooth.
Oil-well rig of the present invention can be realized integral demounting with the rat hole gripping mechanism; Adopt seam to be connected between the first half and the rat hole; The latter half employing bolt and rat hole joint flange down are connected, and are fixed through nut, spring washer, and the mode of iron wire locking realizes insurance.Oil-well rig of the present invention is used the rat hole gripping mechanism, adopts the direct-push structure of left and right hydraulic jack 6, and operating principle is simpler.
Oil-well rig of the present invention with the course of work of rat hole gripping mechanism is:
Drilling tool is put into rat hole, at first contacts with housing 1, and hydraulic jack 6 begins to promote slide block assembly 2 and inwardly advances then, realizes the purpose of clamping drilling tool.The effect that connects hydraulic jack 6 and housing 1 is played in this process middle ear seat I 3, ear seat II 4, stainless steel wire 7, turret head head eye bolt 8, hexagon thin nut 9, spring washer 10, cottor pin 11 etc.
During work, save on housing 1 the first half and the rat hole and be connected through seam, housing 1 the latter half and rat hole joint down are connected through bolt, and hexagon thin nut 9 plays locking and locking effect with spring washer 10.This rat hole gripping mechanism cooperates the top to drive common clamping drilling tool, accomplishes the last shackle function of drilling tool.If when using on the iron driller shackle drilling tool, only need hydraulic jack 6 to drive slide block assemblies 2 and return the two ends initial position, make to be in the opening maximum rating between two pincers teeth 13 that the last shackle that just can not influence drilling tool is moved.When dismantling this rat hole gripping mechanism if desired, the first half firmly proposes to save on the rat hole, and the latter half is dismantled and got final product with the following bolt, hexagon thin nut 9, the spring washer 10 that are connected of saving of rat hole.
