Circular fork

Technical field

The utility model belongs to the engineering drilling field, is specifically related to a kind of circular fork.

Background technology

At present, in the engineering drilling construction, commonly used to fork.Its Main Function: the one, block drilling rod, weighted lever or drill collar when the drilling tool of rig up and down, be fixed on the brill dish of rig, the plus-minus drilling tool ensures safety; The 2nd, conveniently revolve and unload or tighten tool joint.

Existing fork is the long handle fork, and its structure is that front end is U-shaped jaw, and U-shaped jaw rear end is provided with long handle, blocks tool joint with U-shaped jaw during use, and drilling rod is fixed on the position, aperture; After drilling rod is suspended in midair by winch, can rotate long handle and realize that revolving of tool joint unload or tighten.

The use of this long handle fork has solved to a certain extent to revolve and has unloaded the needed operation requirements of drilling rod.But still there is following shortcoming in it: the one, unload or tighten the strength requirement owing to revolving, long handle must reach certain length and requirement of strength, and in practice, the length of long handle is generally 800-1500mm, requires to have simultaneously certain rugosity, this need to use great deal of steel, increases cost.The 2nd, use inconveniently, when it is used for the aperture fixedly during drilling rod, position and angle that must adjustment handle fork make the handle fork place with the aperture chock is vertical, can use; Because long handle length is long, unload or when tightening drilling rod, need larger rotation space revolving, be not easy to operation.

In view of the shortcoming and defect that exists in above-mentioned existing long handle fork, the inventor is actively studied and is innovated, and has has finally researched and developed a kind of circular fork of the present utility model.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as to restriction of the present utility model.

A kind of circular fork as shown in Figure 1 comprises U-shaped jaw, and wherein, U-shaped jaw is the U-shaped breach 2 of round turntable, and U-shaped breach 2 is used for blocking drilling rod or revolving unloading drilling rod; The edge of U-shaped breach 2 is provided with jaw reinforcing rib 31, and the periphery of round turntable 1 is provided with peripheral reinforcing rib 32, is provided with rib reinforcing rib 33 between peripheral reinforcing rib 32 and jaw reinforcing rib 31, and above-mentioned kind of reinforcing rib is used for strengthening the steadiness of fork structure; Be provided with fork handle 4 in the rear end of U-shaped breach 2, fork handle 4 is positioned on the axis of U-shaped breach 2; Be provided with handle 5 on fork handle 4, be used for convenient carrying and load and unload fork.

Embodiment 1, and circular fork comprises U-shaped jaw, and U-shaped jaw is the U-shaped breach 2 of round turntable 1.The present embodiment has solved existing fork steel using amount large by changing existing long handle fork into circular fork, uses the problems such as inconvenience because length is long.

Embodiment 2, on the basis of embodiment 1, are provided with jaw reinforcing rib 31 at the edge of U-shaped breach 2; Periphery at round turntable 1 is provided with peripheral reinforcing rib 32, and the two ends of peripheral reinforcing rib 32 and jaw reinforcing rib 31 are connected as a single entity; Be provided with rib reinforcing rib 33 between peripheral reinforcing rib 32 and jaw reinforcing rib 31.The jaw reinforcing rib 31 of the present embodiment, peripheral reinforcing rib 32 and rib reinforcing rib 33 can be located at the centre of upper surface, soffit or the round turntable of round turntable 1, also can be in higher than upper surface or soffit simultaneously.As another optimal way of the present embodiment, jaw reinforcing rib 31, peripheral reinforcing rib 32 and rib reinforcing rib 33 are located at the upper surface of round turntable 1.The present embodiment has strengthened the stability of intensity, rigidity and the structure of fork in the situation that do not increase the round turntable thickness of circular fork, has reduced simultaneously the manufacturing cost of fork.

Embodiment 3, on the basis of embodiment 2, rib reinforcing rib 33 is set to even number rib reinforcing rib 33 take the axis of U-shaped breach 2 as axis of symmetry, when rib reinforcing rib 33 is even number and symmetrically the time, can guarantee that the both sides of circular fork take U-shaped breach 2 as axis firmly evenly, are difficult for making the fork distortion.

Embodiment 4, on the basis of embodiment 3, are provided with fork handle 4 in U-shaped breach 2 rear ends, fork handle 4 can be connected to round turntable 1 inside rib reinforcing rib 33 or be directly connected to the peripheral reinforcing rib 32 of round turntable 1.As a kind of optimal way of the present embodiment, fork handle 4 is directly connected to peripheral reinforcing rib 32 places of round turntable 1, can make circular fork firm and durable more, guarantees that simultaneously circular fork is in use firmly more even.

Embodiment 5, on the basis of embodiment 4, be provided with handle 5 on the fork handle 4 of circular fork, and handle 5 are located at the upper surface of round turntable 1.Circular fork is used more convenient.

Embodiment 6, on the basis of embodiment 1-5, the front end of the U-shaped breach 2 of circular fork are bell mouth shape.In the process of using, not only can block fast drilling rod, and convenient operation personnel's operation.In use, one of operating personnel hold handle 5, and another holds U-shaped jaw 2 front ends and can be rotated, and facilitates its use and time saving and energy saving.

Circular fork of the present utility model and traditional long handle fork not only structurally exist and improve, and have improved further force mechanism and the fixed form of fork.
