Electric Winch Motor - Trucks
The present invention pertains to an electric winch for winding and unwinding cable, and specifically to a winch having an inner electric motor and to a way of raising and lowering down gap tools utilizing the winch.
The cumulative inertialmovement results in inefficiency and wasted vitality. The direct drive system of the current invention transfers power directly to the drum and is way more efficient. There are far much less moving parts and the winch is far lighter; due to this fact there may be lessenergy loss. The lighter drawworks of the present invention, having less inertial motion, makes it nicely suited to offshore drilling operations topic to heave and wave forces.
The rotor (18) rotates in regards to the stator (16) on bearings (20) discovered at every finish of the stator. Any acceptable bearing system as can be generally utilized by one expert in the artwork could also be used in the electric winch of the current inventionincluding with out limitation, roller bearings, angular contact bearings, spherical bearings, ceramic bearings, plain bearings and magnetic bearings. The bearing assembly is sealed to stop the entry of debris or overseas matter into the space betweenthe stator (16) and the rotor (18). The electric winch has inspection ports (32) for checking that the bearings are appropriately greased. Unlike standard winch programs, the electric winch of the current invention requires comparatively minimalgreasing and lubrication and additional, it requires much less maintenance than a conventional winch system. With a sealed bearing system, the system only requires greasing roughly twice a 12 months. If a magnetic bearing system is used, no such maintenanceis required.
Unlike a traditional winch system, the electric motor (19) is used for the entire braking of the drum (12) nonetheless, in the occasion of a lack of energy supply, similar to a brown out or black out, separate emergency brakes could be utilized. Anysuitable forms of brakes may be used with the drawworks of the present invention for such emergencies together with without limitation, band brakes, caliper brakes, Eaton brakes, water cooled brakes or disc brakes. FIG. 3 exhibits a winch with band brakes(28). FIG. If you have any issues with regards to where by and how to use magnetic drum, written by Court Khotol Se Gov,, you can get hold of us at the webpage. Four reveals an end view of the drum (14) with caliper brakes (30). The brakes may also be used in a parking brake kind method if desired.
When the electric winch is used as a drawworks winch for winding and unwinding drilling line to raise and lower down gap equipment, there are an a variety of benefits. The drawworks is smaller and lighter taking less space on the drilling deck. This also allows the drawworks to be placed closer to the borehole or, alternatively, further away from the bore hole. If placed additional away, this provides for magnetic drum a bigger workspace for the rig hands to work and allows the position of additionalequipment equivalent to an iron roughneck. The drill arms should not uncovered to the hazard of an exterior energy supply and the drawworks is way quieter, again creating a safer work setting. The drawworks using the electric winch of the current inventiondoes not require a lubrication system and requires comparatively less maintenance. The drawworks of the present invention is light enough to go away in the substructure when a rig is moved from well to nicely, and it small sufficient that it may be placed inpositions that typical drawworks can't be placed in, akin to between the A-legs of a rig, additional back within the rig substructure, or on matting pinned to the substructure.
The elements of the winch of the present invention may be constructed from any suitable materials together with with out limitation steel and iron and alloy mixtures of the same. Any materials used must have the ability to withstand the wear and torque thatthey can be subjected to as a part of a winch system.
