Abstract
The utility model relates to a kelly bushing aligning device which comprises a U-shaped groove and a T-shaped handle. The T-shaped handle is connected with the side wall of the U-shaped groove, and threads are arranged on the end portion of the T-shaped handle. The kelly bushing aligning device has the advantages of being simple in structure, low in manufacturing cost, easy to operate, and time-saving and labor-saving.
Description
Technical field
The utility model relates to a kind of oil drilling and repairing machine drilling well aid, relates in particular to a kind of master bushing aligning device.
Background technology
The oil drilling and repairing machine carries and whenever adds drilling rod in the drilling process and just need align master bushing again and bore Pan Kou.Master bushing is the device that TORQ is passed to kelly bar, when adding drilling rod, all kelly bar must be mentioned, because master bushing is installed on the kelly bar, so also master bushing is mentioned when mentioning kelly bar at every turn.The master bushing outside be square corresponding with the brill dish, brill dish excessive velocities, so operate the brill dish with master bushing and brill dish to what waste time and energy very much just, in order to align, the continuous folding switch of operating personnel comes centering, has wasted a large amount of working times.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model provides a kind of master bushing aligning device, and is time saving and energy saving, simple to operate.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of master bushing aligning device comprises U-lag, T shape handle, and T shape handle is connected with the U-lag sidewall, and described T shape handle end is provided with screw thread.
Compared with prior art, the beneficial effects of the utility model are:
Simple in structure, cost of manufacture is low, and is simple to operate, time saving and energy saving.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a upward view of the present utility model.
Among the figure: 1-U shape groove 2-kelly bar 3-T shape handle.
The specific embodiment
Below in conjunction with Figure of description the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 1, Fig. 2, a kind of master bushing aligning device comprises U-lag 1, T shape handle 3, and T shape handle 3 is connected with U-lag 1 sidewall, and described T shape handle 3 ends are provided with screw thread.
Embodiment:
U-lag 1 adopts the steel plate of thickening to make, and the U-shaped mouth is of a size of 80mm * 150mm.At the boring of a side center of U-lag 1, tapping; T shape handle 3, pushing end mantle fiber, consistent with the screwed hole on the U-lag 1.Reach is greater than 130mm.T shape handle 3 is screwed in the U-lag 1, determines headspace, utilize this device to clamp kelly bar 2 then, push away T shape handle 3 and make kelly bar 2 rotate, master bushing and brill dish are aligned, transfer drilling rod according to different drilling rods., manpower drives the slow control easily of hydraulic pressure puffer speed if can't promoting the available hydraulic puffer.
The utility model is simple in structure, and cost of manufacture is low, and is simple to operate, time saving and energy saving.
