An emergency drive device for vehicle-mounted oil drilling rig

Abstract

The invention discloses an emergency drive device for a vehicle-mounted oil drilling rig, comprising a motor reducer, an input sprocket is installed at the output end of the motor reducer through a flat key, and the input sprocket is connected to the output sprocket through a chain. Transmission connection, the outside of the input sprocket and the output sprocket is closed and installed with a chain box, the upper side of the chain box is installed with a lubricating oil path arrangement, the output sprocket is installed on the corner box sprocket through a bearing, so A hanging sleeve is installed on the spline sleeve at the shaft end, and the angle box sprocket is connected to the winch through a chain drive. High transmission efficiency and long service life of components; ensure the rigidity of the chain box hooking position, and the splash lubrication of the sprocket ensures that the hooking mechanism is very easy and smooth even if it is not used for a long time; it does not occupy the aisle, which is convenient for people on both sides of the car To the opposite aisle; it can extend the life of the output shaft bearing to a great extent; this can reduce the space in the axial direction and make it easier to arrange on the truck-mounted oil rig.

Description

technical field [0001] The invention relates to the field of oil drilling rigs, in particular to an emergency driving device for a vehicle-mounted oil drilling rig. Background technique [0002] The winter in Russia is relatively cold, the surface temperature is relatively low, and the environment is relatively harsh. When the engine fails, the drill pipe cannot be driven to rotate or lift. Under extremely low temperature, if the drill pipe stops moving for a long time, it will cause ice to freeze on the mud, and the drill pipe will be frozen and cannot move. The drilling rig standard requires that the drilling rig must be equipped with an emergency drive device. When a fault occurs and the engine needs to be shut down for maintenance, the emergency drive can drive the drill pipe to move up and down at a low speed through the winch, thereby avoiding the risk of the drill pipe being frozen. [0003] The traditional emergency power source is an open gear transmission mechanis...

AI Technical Summary

Problems solved by technology

[0003] The traditional emergency power source is an open gear transmission mechanism, and the lubrication is grease lubrication. The gears cannot be continuously and effectively lubricated, the gears wear quickly, the noise is high, the maintenance cost is high, and the running time is limited. It is very difficult to engage after long-term non-use

The traditional emergency power source is arranged at the input end of the corner box. The corner box needs to run when in use, and it cannot work when the corner box fails.

The traditional emergency power source is located in the middle of the car, and the motor reducer is arranged horizontally, which blocks the aisles on both sides of the car drilling rig, which is very inconvenient

The last gear of the transmission box cantilever is arranged on the input shaft of the corner box. When the emergency drive is running, the radial force of the gear acting on the shaft is relatively large, which will greatly reduce the life of the input bearing of the corner box.
