Abstract
The utility model discloses an independent driving rotary table apparatus for petroleum drilling machine comprising a rotary table, a sprocket wheel coupling, a brake disc, a motor, and a base, wherein the rotary table is mounted on the base, an input shaft of the rotary table is connected to one end of the sprocket wheel coupling, the other end of the sprocket wheel coupling being connected to the motor through the brake disc, the motor being fixed to the base, the periphery of the sprocket wheel coupling being also provided with a protective cover. Compared with prior art technology, the utility model can realize stepless speed control, and has the advantages of simple structure, convenient dismounting, less middle transmission pair, high transmission efficiency, large brake moment, reliable brake, simple lubrication, and less maintenance.
Description
One, technical field
The utility model relates to oil-well rig turntable actuation techniques field, is specifically related to a kind of drive rotating-table apparatus that is used for oil-well rig.
Two, background technology
Hydraulic pressure drive rotating-table apparatus is the ground slewing of rig deceleration drilling rod rotary drilling, provides power by fluid pressure drive device and sprocket wheel shaft joint for rotating disk.It mainly act as: drilling tool in the deceleration well, and enough big moment of torsion and necessary rotating speed is provided; Setting of casing and when making a trip, whole weight of sleeve pipes and drill string in the support well; Finish the drill bit of unloading, back-off during the processing accident, advance back works such as button.
Traditional in the past rotating disk drive device generally adopts motor to pass through gear reduction box, universal drive shaft is given rotating disk with power transmission, drive disk operation, this kind of drive complex structure, middle transmission is more, transmission efficiency is low, bulk is big, and the cost height, can not realize helicopter integral hoisting etc.
Three, utility model content
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of drive rotating-table apparatus that is used for oil-well rig is provided.
Its technical scheme is: the utility model comprises rotating disk, sprocket wheel shaft joint, brake disc, motor and base, and rotating disk is installed on the base.The power shaft of described rotating disk is connected with an end of sprocket wheel shaft joint, and the other end of sprocket wheel shaft joint is connected with motor by brake disc; Motor is fixed on the base.
Wherein, the periphery of described sprocket wheel shaft joint also is provided with protective cover.
The utility model has following advantage compared with prior art: 1, simple in structure, convenient disassembly 2, can realize stepless speed regulation; 3, middle transmission is few, the transmission efficiency height; 4, brake torque is big, and braking is reliable; 5, lubricated simple, safeguard few.
Four, description of drawings
Accompanying drawing is the structural representation of a kind of embodiment of the utility model.
Five, the specific embodiment
With reference to accompanying drawing, a kind of drive rotating-table apparatus that is used for oil-well rig comprises rotating disk 2, sprocket wheel shaft joint 4, brake disc 5, motor 6 and base 1, and rotating disk 2 is installed on the base 1.The power shaft of described rotating disk 2 is connected with an end of sprocket wheel shaft joint 4, and the other end of sprocket wheel shaft joint 4 is connected with motor 6 by brake disc 5; Motor 6 is fixed on the base 1.The periphery of sprocket wheel shaft joint 4 also is provided with protective cover 3.
During operation, sprocket wheel shaft joint 2 can guarantee higher axiality, and chain gear transmission is steady, and lubricated employing grease lubrication is simple and convenient, splashes for preventing grease, increases protective cover 3 outside sprocket wheel shaft joint 4.
The utility model adopts sprocket wheel shaft joint 4 to connect, and advantage is to safeguard simple, and convenient disassembly only needs during dismounting shaft joint protective cover 3 is pulled down, and can be lubricated or change chain.Brake disc 5 is stopped for pneumatic dish, and brake torque is big, and braking is reliable, changes simple and convenient.Adopt flange to be connected between brake disc 5 and sprocket wheel shaft joint 4 and the motor 6, simple in structure, compactness.
The above is a preferred implementation of the present utility model; should be noted that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
