The utility model is related to water drilling rig part, and in particular to a kind of water drilling rig gearbox.
Background technology
With social development, country increasingly focuses on town and country infrastructure construction, particularly rural safty of drinking water, and
Farmland irrigation water.And these water resources need to dig a well to realize by well sinker.
The key position of well sinker is its gearbox, and it is the key position of well-digging machine equipment.And existing well sinker
Gearbox designs are simple, no matter run into that rotating speed is unified on what stratum, it is impossible to realize gearshift adjustment during well-digging.Cause well-digging
Frequently, complicated stratum limits well-digging operation to construction problem.
Content of the invention
The purpose of this utility model is to provide a kind of water drilling rig gearbox, can carry out high and low shelves speed governing, for difference
The different speed of stratum adjustment, effectively improves well-digging engine efficiency, and prevention drilling rod is twisted off.
For achieving the above object, the utility model is employed the following technical solutions：Water drilling rig gearbox, including input
Power is passed to output shaft by splined shaft and power transmission shaft by axle, output shaft, shift fork and shift fork axle, the input shaft, and shift fork is installed
In shift fork axle, splined shaft is from top to bottom sequentially installed with the first gear that double crosslinking sliding gear is engaged with output shaft, and duplex is slided
Move gear be provided with splined shaft coordinate internal spline portion, power transmission shaft be from top to bottom disposed with second gear, the 3rd gear and
4th gear, double crosslinking sliding gear can be driven by shift fork and axially move along splined shaft, make second gear and duplex sliding tooth
The gear engagement of wheel or the 3rd gear are engaged with the lower gear of double crosslinking sliding gear, the 5th tooth on the 4th gear and output shaft
Wheel engagement.
The input of the input shaft is fixed with sprocket wheel.
The input shaft, output shaft, splined shaft and power transmission shaft are fixed in transmission case body by bearing respectively, speed changer
Lid is provided with above casing, and input shaft, output shaft, splined shaft are fixedly connected with Shang Gai by bearing respectively with power transmission shaft.
The output shaft lower end is fixed with ring flange, and the 5th gear is fixedly connected with ring flange by bolt, ring flange with
Separation sleeve is provided between the bearing of output shaft upper end.
The beneficial effects of the utility model are：Shift fork drives double crosslinking sliding gear to axially move along splined shaft so that double
Connection shifting slide gear is engaged with second gear or the 3rd gear, is realized high and low shift speed governing, is effectively prevented drilling rod from twisting off, and reduces bit grinding
Damage speed.
