According to the top-drive split type gear case, the output shaft of the motor and the top-drive main shaft are coaxially arrangement, therefore, limitation of the size of the motor is little, the whole size of top drive is reduced, the load-bearing effect of a top-drive gear case is improved, the machining cost is reduced, and difficulties of daily maintenance work are reduced.
Description
Technical field
The utility model relates to the oil electromechanical engineering, and the detachable gear wheel case is driven on especially a kind of top.
Background technique
As shown in Figure 1, domestic and international at present each model top is driven and is all adopted single gear-box 1 to realize double reduction.Because gearbox output shaft (main shaft is driven on the top) must be put middle layout, make the slurry channel assembly (washing pipe mechanism) that is connected with this also must put middle installation, two, single motors can only be installed in the left and right sides of washing pipe mechanism center line and back partially (deflection guide rail one side), it is bigger that this causes the top to drive on length, width both direction size, makes that this not spacious derrick inner space is narrower.
In some occasions of shallow well probing, need to use little tonnage top to drive, this class top is driven and is adopted single motor driving, at this moment because the weight of motor is bigger, the problem that the biasing of motor has also brought gear-box seriously to lay particular stress on, normal go up shackle, round trip are driven in the influence top.Some producers are also arranged abroad, in order to satisfy motor demand of placing placed in the middle, with the structure complicated of motor, the output shaft of motor is made hollow, slurry channel is positioned at wherein.But invisible like this having increased pushes up the research and development and the processing cost of driving, and brings difficulty for simultaneously daily maintenance work.
The model utility content
At the problem that prior art exists, the purpose of this utility model is to provide a kind of structure through improving, and pushes up the overall dimensions that drives thereby dwindle, and the improvement top is driven the top of gear-box load-bearing effect and driven the detachable gear wheel case.
For achieving the above object, the detachable gear wheel case is driven on the utility model top, the upper gear box and the lower tooth roller box that comprise the double reduction transmission, upper gear box, lower tooth roller box are respectively realized the one-level deceleration, upper gear box links to each other with motor output shaft, is connected by the major axis that compound gear is set between upper gear box and the lower tooth roller box, and the lower tooth roller box drives main shaft with the top and is connected, main motor drives main shaft with transmission of power to the top by the two-stage gear-box, drives the drilling tool rotation and finishes drillng operation.
Further, the main shaft arranged concentric is driven on described motor output shaft and top.
Further, the space between described upper gear box and the lower tooth roller box is provided with slurry channel.
Further, described compound gear comprises the gearwheel that is arranged on major axis top, the small gear of major axis bottom.
Further, described upper gear box comprises three pinions that match: described gearwheel, idle pulley and motor output shaft gear, under the situation that does not change velocity ratio, in order to piece together central moment, idle pulley is arranged between gearwheel and the motor output shaft gear, and the motor output shaft gear is arranged on the described motor output shaft.
Further, described lower gear case comprises two pinions that cooperatively interact: described small gear and main shaft gearwheel, the main shaft gearwheel is installed in described top and drives on the main shaft.
The utility model drives the main shaft arranged concentric with motor output shaft and top, makes motor size limited less, and dwindles the overall dimensions that drive on the top, and improves the top and drive gear-box load-bearing effect, has reduced processing cost, has reduced the difficulty of maintenance work.

Embodiment
Below, with reference to the accompanying drawings, the utility model is more fully illustrated, exemplary embodiment of the present utility model has been shown in the accompanying drawing.Yet the utility model can be presented as multiple multi-form, and should not be construed as the exemplary embodiment that is confined to narrate here.But, these embodiments are provided, thereby make the utility model, and scope of the present utility model is fully conveyed to those of ordinary skill in the art comprehensively with complete.
In order to be easy to explanation, here can use such as " on ", D score " left side " space relative terms such as " right sides ", be used for element shown in the explanatory drawing or feature relation with respect to another element or feature.It should be understood that except the orientation shown in the figure spatial terminology is intended to comprise the different azimuth of device in using or operating.For example, if the device among the figure is squeezed, be stated as the element that is positioned at other elements or feature D score will be positioned at other elements or feature " on ".Therefore, the exemplary term D score can comprise upper and lower orientation both.Device can otherwise be located (revolve turn 90 degrees or be positioned at other orientation), and the relative explanation in used here space can correspondingly be explained.
To shown in Figure 5, the detachable gear wheel case is driven on the utility model top, comprises the upper gear box 2 and the lower tooth roller box 3 of double reduction transmission as Fig. 2, is connected by the major axis 4 that compound gear is set between upper gear box 2 and the lower tooth roller box 3.Compound gear comprises the gearwheel 9 that is arranged on major axis 4 tops, the small gear 5 of major axis 4 bottoms.
In the utility model, motor power passes to the top via motor output shaft 13, motor output shaft gear 12, idle pulley 10, major axis top gearwheel 9, major axis 4, major axis lower pinion 5, main shaft gearwheel 11 successively and drives main shaft 6, finishes drillng operation thereby drive the drilling tool rotation.
And motor output shaft 7 drives main shaft 6 arranged concentric with the top in the utility model, makes motor size limited less, and dwindles the overall dimensions that drive on the top, and gear-box load-bearing effect is driven on the improvement top.Owing to adopt the design of detachable gear wheel case, the upper gear box 2 of double reduction transmission is scattered in up-down structure with lower tooth roller box 3, slurry channel 8(washing pipe mechanism is just given in the space of reserving between upper gear box 2 and the lower tooth roller box 3) be provided with installing space, like this, under the prerequisite that does not influence slurry channel, it is concentric to have realized that main shaft is driven on motor output shaft and top, has saved the top and has driven overall dimensions, avoided the biasing of motor, improved and pushed up the stressing conditions that drives gear-box.And then reduced processing cost, reduced the difficulty of maintenance work.
