Problems solved by technology

At present, thrust tapered roller bearings are used in the faucets of oil drilling rigs. This type of bearing has limited load capacity and limited service life. Usually, the main bearing must be replaced every certain time. The specific replacement cycle depends on the manufacturer. It is related to the type of the main bearing and the carrying capacity of the faucet, which causes the faucet device to be overhauled at regular intervals, reduces the utilization rate of the equipment, and causes economic waste

Embodiment Construction

[0025] The present invention will be further described below in conjunction with accompanying drawing:

[0026] Such as figure 1 As shown, the new faucet device of the oil drilling rig mainly includes a hydraulic station device 11, a motor device 1, a gooseneck device 2, a lifting ring 3, a packing device 4, a center pipe 10, a casing upper cover 5, a casing 6, and a sliding bearing 8 And the bearing seat 9, the bearing seat 9 is installed on the outside of the center pipe 10 at the lower end of the shell 6.

[0027] The upper end of the lifting ring 3 is hung on the main hook of the hook, and the lower end is connected to the shell 6 by the lifting ring pin. The motor device 1 is installed on the top of the housing loam cake 5, and it drives the rotation of the central tube 10 by a pair of external gears. The casing upper cover 5 is connected with the casing 6 through screws, and the casing 6 is connected with the oil tank 11 through a pipeline. The gooseneck device 2 is in...

Abstract

The invention relates to a water tap device for an oil rig. The water tap device comprises a motor device, a gooseneck tube device, a packing device, a center tube and a casing, wherein the lower end of the gooseneck tube device is connected with the upper end of the packing device; the lower end of the packing device is connected with the center tube; the upper part of the center tube is connected with the motor device; the middle of the center tube is arranged in the casing; and a sliding bearing connected with the center tube is also arranged in the casing. A main load is born by the sliding bearing comprising a thrust disc and a thrust pad; the bearing capacity of the sliding bearing is strong; the service life of the sliding bearing is prolonged by multiple times compared with that of a thrust tapered roller bearing; the overhaul cycle of the water tap device is prolonged; the safe reliability of the water tap device is enhanced; and the operation performance of the oil rig is improved.

Description

technical field [0001] The invention relates to the technical field of oil drilling rigs, in particular to a faucet device for an oil drilling rig. Background technique [0002] The faucet device is one of the key components of the oil drilling rig. In addition to the function of conveying high-pressure mud, it also needs to increase the load of the drill string. The motor device can be used to drive the rotation of the center pipe and complete the auxiliary work of lifting the drill floor. . Specifically, the faucet device is used to bear the weight of the drill string (i.e. the main load) and the central pipe of the faucet is a hollow structure, which is used as a drilling fluid channel (i.e. mud), and the mud pumped from the mud tank by the mud pump passes through the hose The device, the gooseneck device, the central pipe of the faucet, and the central hole of the drill string reach the borehole and the well wall, and are used to cool the drill bit, protect the well wal...
