Description
technical field:
The utility model relates to a kind of multi-functional lower fork, belongs to drilling equipment technical field.
background technology:
At present, in some large-scale water drilling rigs, exploratory drilling rig, be provided with lower fork, in order to installation, dismounting drilling rod, function singleness, operation inconvenience.Rig needs to change backing plate, fork and well head plate, complicated operation in installation, work, unloading process, and the labour intensity of workman is large, inefficiency.
summary of the invention:
The purpose of this utility model is the deficiency in order to overcome existing lower fork, provides a kind of function many, easy to operate, the multi-functional lower fork of safety and stability.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of multi-functional lower fork, comprise fork body, described fork body is processed by rectangle steel plate, is provided with rectangle boss at the middle part of fork body, increases intensity and the support force of fork body further.Be provided with a circular hole at the middle part of rectangle boss, the center of circle along circular hole is provided with bar shaped patchhole with the line of fork body front end mid point, and the rear end of bar shaped patchhole communicates with circular hole, bar shaped patchhole be designed to "eight" shape foremost, be convenient to insertion drilling rod.Circular hole just after boss in be provided with the removal hole just right with bar shaped patchhole, the rear end of removal hole is semicircle, the front end of removal hole communicates with circular hole, one piece of non-slipping block is respectively provided with on the boss of the both sides of the front end of removal hole, when installation, dismounting drilling rod, can drilling steel slip be prevented, avoid drilling rod to fall in drilling well from circular hole.Fork handle is provided with in the rear end of fork body.
The rear end of described fork handle is welded with a pushing hands, and pushing hands is 30-60 ° with the angle of fork body soffit, is convenient to fork under push-and-pull, easy to operate.
Described non-slipping block is wedge shape, and front end is low, and rear end is high, has both been convenient to pitch into drilling rod, can prevent drilling steel slip again.
The diameter of described circular hole is greater than the diameter of drilling rod, and during work, drilling rod is placed in circular hole, and restriction drilling rod, prevents drilling rod run-off the straight phenomenon.
The beneficial effects of the utility model are, structure is simple, is easy to processing and manufacturing, flexible and convenient operation, safe and reliable, achieve well head plate, design concept that backing plate, fork function are integrated in one, the stroke not only alleviate weight, also need not pull out completely, advance along guide rail, pulling out is short.Alleviate the labour intensity of workman, improve operating efficiency.
accompanying drawing illustrates:
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1 fork body, 2 fork handles, 3 pushing hands, 4 boss, 5 non-slipping blocks, 6 circular holes, 7 bar shaped patchholes, 8 removal holes in figure.
detailed description of the invention:
As shown in Figure 1, a kind of multi-functional lower fork, comprise fork body (1), described fork body (1) is processed by rectangle steel plate, is provided with rectangle boss (4) at the middle part of fork body (1), increases intensity and the support force of fork body (1) further.Be provided with a circular hole (6) at the middle part of rectangle boss (4), the diameter of circular hole (6) is greater than the diameter of drilling rod, and during work, drilling rod is placed in circular hole (6), and restriction drilling rod, prevents drilling rod run-off the straight phenomenon.The center of circle along circular hole (6) is provided with bar shaped patchhole (7) with the line of fork body (1) front end mid point, and the rear end of bar shaped patchhole (7) communicates with circular hole (6), bar shaped patchhole (7) be designed to "eight" shape foremost, be convenient to insertion drilling rod.Circular hole (6) just after boss (4) in be provided with the removal hole (8) just right with bar shaped patchhole (7), the rear end of removal hole (8) is semicircle, the front end of removal hole (8) communicates with circular hole (6), one piece of non-slipping block (5) is respectively provided with on the boss (4) of the both sides of the front end of removal hole (8), when installation, dismounting drilling rod, can drilling steel slip be prevented, avoid drilling rod to fall in drilling well from circular hole (6).Fork is provided with (2) in the rear end of fork body (1).Fork is welded with a pushing hands (3) the rear end of (2), and pushing hands (3) is 30-60 ° with the angle of fork body (1) soffit, is convenient to fork under push-and-pull, easy to operate.Non-slipping block (5) is wedge shape, and front end is low, and rear end is high, has both been convenient to pitch into drilling rod, can prevent drilling steel slip again.
Operating principle and operating process: be provided with rectangle boss (4) at the middle part of fork body (1), increase intensity and the support force of fork body (1) further.Fork body (1) is provided with circular hole (6), bar shaped patchhole (7) and removal hole (8), and three holes are all to pitch the axis of symmetry of body (1) for axis of symmetry, achieve well head plate, design concept that backing plate, fork function are integrated in one, not only alleviate weight, also the stroke need not pull out completely, advance along guide rail, pulling out is short.Alleviate the labour intensity of workman, improve operating efficiency.When carrying brill, when the lower end bayonet socket of first drilling rod is carried to upper cover plate place, push the bayonet socket of the upper end of multi-functional lower fork to the second drilling rod along guide rail, block second drilling rod, non-slipping block (5) holds out against drilling rod, prevents drilling steel slip.After unloading first drilling rod, when elevator hooks second drilling rod top, pull out multi-functional lower fork, make drilling rod slide into circular hole (6), elevator is proposed.During work, drilling rod is placed in circular hole (6), and drilling rod is placed in circular hole (6), and restriction drilling rod, prevents drilling rod run-off the straight phenomenon.
