Abstract
The utility model discloses a power tong which comprises an upper casing, a middle casing and a lower casing, wherein the upper casing, the middle casing and the lower casing are integrated through the idle pulley shaft. The utility model has a simple, reliable and reasonable structure which ameliorates the structure performance of the prior power tong, further effectively elongating the working life and improving the working reliability.
Description
The utility model relates to the power tongs of using in the drilling operation of a kind of oil field.
The available dynamic tong, as the liquid gas tong of the patent No. 90102517, its housing is split type, comprises upper casing, mesochite, lower casing, wherein upper casing and mesochite are connected with idler shaft location, bolt, lower casing and mesochite with little alignment pin locate, bolt is connected.In the power tongs operation process, lower casing is because the bigger axial force that produces when being subjected to gear drive, and the little alignment pin of its connection and bolt distortion occurs or shear, and cause lower casing that the dislocation or the phenomenon that drops take place, thereby power tongs can't normally be used, and cause certain loss thus.
The purpose of this utility model is to provide the power tongs of a kind of rational in infrastructure, long service life, reliable operation.
Technical solution of the present utility model is:
A kind of power tongs comprises upper casing, mesochite, lower casing, and the difference of itself and prior art is: upper casing, mesochite, lower casing connect into integral body by idler shaft.
The utility model has born the bigger radial load that produces in the gear drive process owing to adopt the bigger idler shaft of intensity, and the connecting bolt of upper and lower shell and mesochite can not be out of shape or shear, and upper and lower shell can not misplace or drop in operation process yet.The utility model features simple structure is reliable, reasonable, has improved the structural performance of existing power tongs, and application life and the functional reliability that improves product had remarkable result.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the front view of an embodiment of the utility model.
Fig. 2 is the vertical view of Fig. 1 embodiment.
Fig. 3 is the housing partial view of Fig. 1 embodiment.
Fig. 4 is the A-A view of Fig. 3.
A kind of power tongs, gear shaft 3 is installed between mesochite and the lower casing, transmission of power is arrived gear wheel 7, gear wheel 7 and spline gear 5 are contained on the splined shaft between upper casing and the lower casing 6, spline gear 5 passes to breach gear wheel 10 with power through idle pulley 9, carries out the clamping and the spinner operation of power tongs.Idle pulley 9 is contained on the idler shaft 8, and idler shaft 8 connects into integral body with upper casing 1, mesochite 2, lower casing 4.Idle pulley, idler shaft all have two, are positioned at the both sides of housing.
