Abstract
The utility model relates to a chain box of an independent rotating disk driving device on an oil rig. The chain box comprises an input shaft assembly, an output shaft assembly, a chain, a gearshift, a box body, a forced lubrication mechanism and a brake device, wherein the box body is internally provided with the chain, the input shaft assembly and the output shaft assembly are connected through the chain, the output shaft assembly is connected with a rotating disk, the output shaft assembly is provided with the gearshift, and the chain is lubricated through the forced lubrication mechanism. The chain box disclosed by the utility model has the advantages that the chain box is of an integrated structure, and the assembling and the disassembling are convenient; lubrication is carried out by adopting a forced spraying lubrication mode, and thus the service life of the chain is greatly prolonged; the speed is changed through two gears of the gearshift, and the speed regulation range is increased.
Description
Technical field
The utility model relates to a kind of oil-well rig top rotary table independent driving device drive chain case.
Background technology
During oil-well rig work, the power of rotating disk is to be provided by motor or diesel engine, through transmission device, passes to rotating disk.At present, use chain gearing transmission, this chain gearing gear is few, and rotating disk speed adjustable range is little, separately the inertia brake device of fitting rotary disk.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of oil-well rig top rotary table independent driving device drive chain case, increases speed adjustable range.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of oil-well rig top rotary table independent driving device drive chain case, comprise power shaft assembly, output shaft assembly, chain, gearshift, casing, forced feed lubrication mechanism, brake gear, in casing, be provided with chain, power shaft assembly is connected by chain with output shaft assembly, output shaft assembly is connected with rotating disk, output shaft assembly is provided with gearshift, and chain is lubricated by forced feed lubrication mechanism.
Forced feed lubrication mechanism is provided with lubrication hole, and lubrication hole is corresponding with chain, and lubrication oil flows on chain by lubrication hole.

Fig. 3 is gearshift top view.
In figure: the 1-power shaft assembly 2-casing 3-forced feed lubrication 4-of mechanism output shaft assembly 5-brake gear 6-gearshift 7-ring 8-shift fork 9-connecting rod 10-shift handle 11-lubrication hole 12-chain.
The specific embodiment
Below in conjunction with Figure of description, the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 1, a kind of oil-well rig top rotary table independent driving device drive chain case, comprise power shaft assembly 1, output shaft assembly 4, chain 12, gearshift 6, casing 2, forced feed lubrication mechanism 3, brake gear 5, in casing 2, be provided with chain 12, power shaft assembly 1 is connected by chain 12 with output shaft assembly 4, output shaft assembly 4 is connected with rotating disk, and output shaft assembly 4 is provided with gearshift 6, and chain 12 is lubricated by forced feed lubrication mechanism 3.
Forced feed lubrication mechanism 3 is provided with lubrication hole 11, and lubrication hole 11 is corresponding with chain 12, and lubrication oil flows on chain 12 by lubrication hole 11.
Gearshift 6 comprises that shift fork 8, ring 7, connecting rod 9, shift handle 10, shift fork 8 two ends are connected with ring 7, and shift fork 8 bottoms are connected with connecting rod 9, and connecting rod 9 ends connect shift handle 10, and ring 7 is connected with output shaft assembly 4.
Power source is inputted by power shaft assembly 1 spindle nose, and 1 rotation of band driven input shaft assembly, passes to output shaft assembly 4 by driving chain 12, by output shaft assembly 4, gives rotating disk transferring power.All oil sites in casing 2 all can carry out forced feed lubrication by forced feed lubrication mechanism 3, and chain 12 is corresponding with lubrication hole 11, and lubrication oil flows on chain 12 by lubrication hole 11, are chain greasisng.By pulling the shift handle 10 of gearshift 6, realize the gearshift speed governing of casing.When the inertia brake of needs rotating disk, by gas control, operate to 5 one gas signals of inertia brake device, 5 work of inertia brake device, realize the inertia brake of rotating disk.
The utility model is integral type structure, easy installation and removal; Adopt and force spray lubrication mode lubricated, chain is increased application life greatly; By two grades of speed changes of gearshift, increase speed adjustable range, increase the inertia brake device of rotating disk simultaneously, facilitate the urgency of emergency to stop.
