Abstract
The utility model relates to the technical field of drilling rigs, in particular to a three-shaft petroleum drilling drawwork. A motor of the three-shaft petroleum drilling drawwork is connected with an input shaft, the input shaft and an intermediate shaft are connected with a drum shaft through chains, a shifting mechanism is arranged on the intermediate shaft, a low-speed clutch is arranged on the left end of the drum shaft, a high-speed clutch is arranged on the right end of the drum shaft, a hydraulic disk brake is mounted on the drum shaft, a water pipeline, a lubricating system and an air pipeline are welded on a skid, an electromagnetic eddy current brake is arranged on the drum shaft and is connected with the drum shaft through a toothed spline clutch, and fast line guard rollers are mounted on the top of the drawwork. The three-shaft petroleum drilling drawwork has a simple structure, is small and light, and is convenient to operate, maintain and transport. The three-shaft petroleum drilling drawwork overcomes the defects of the conventional 50D three-shaft petroleum drilling drawwork, i.e. complex structure, large size, heavy weight and inconvenience in operation, maintenance and transportation.
Description
Technical field:
The utility model relates to a kind of oil-well rig technical field, particularly a kind of three axle petroleum drilling winchs.
Background technology:
Existing 50D three axle petroleum drilling winchs are because following defective can not satisfy existing drilling technology to the requirement of winch.
One, winch is Split type structure, and size is larger, needs many cars to transport.
Two, winch is provided with the cat shaft part, and with dragging for husky cylinder; Because oil-well rig all adopts hydraulic catwork both at home and abroad, dragging for sand has specialized equipment; So it is meaningless that this part just seems.
Three, weight is large, and installation and transportation are all very inconvenient.The space of drilling floor surface own is very limited, because the winch size is too large, it is crowded that table top just seems.From safety, operation, safeguard that the aspect is all very inconvenient.
Four, existing 50D winch structure is too complicated, and common driller is difficult to grasp its operation and maintenance method, and correct use rig is brought very large hidden danger.
The utility model content:
The technical problems to be solved in the utility model provides a kind of three axle petroleum drilling winchs, and this device has been realized simple in structure, and volume is little, and is lightweight, operation, maintenance, convenient transportation.Overcome existing 50D three axle petroleum drilling winch complex structures, volume is large, and weight is large, operation, maintenance, the inconvenient deficiency of transportation.
Technical solution adopted in the utility model is: a kind of three axle petroleum drilling winchs, comprise drum shaft and winch, and drum shaft is installed on the winch; Motor is connected with input shaft, input shaft, tween drive shaft are connected with drum shaft by chain, tween drive shaft is provided with gearshift, the drum shaft left end is provided with low-speed clutch, right-hand member is provided with high-speed clutch, and hydraulic disc brake is installed on the drum shaft, and waterpipe, lubricating system and air duct are welded on the end sled, electromagnetic eddy current brake is located on the drum shaft and by tooth-like splined clutch and connects, and the winch top is equipped with fast line gear rod.
The beneficial effects of the utility model are: the utility model has been owing to adopted as above structure, thereby has simple in structurely, and volume is little, lightweight advantage, operation, maintenance, convenient transportation.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is front view of the present utility model.
Fig. 2 is structural representation of the present utility model.
The specific embodiment:
As shown in Figure 1 and Figure 2, a kind of three axle petroleum drilling winchs comprise drum shaft 1 and winch 6, and drum shaft 1 is installed on the winch 6; Motor 14 is connected with input shaft 2, input shaft 2, tween drive shaft 5 are connected with drum shaft 1 by chain 12, tween drive shaft 5 is provided with gearshift 3, drum shaft 1 left end is provided with low-speed clutch 10, right-hand member is provided with high-speed clutch 16, and hydraulic disc brake 4 is installed on the drum shaft 1, and waterpipe 7, lubricating system 8 and air duct 9 are welded on the end sled, electromagnetic eddy current brake 13 is located on the drum shaft 1 and by tooth-like splined clutch 15 and connects, and winch 6 tops are equipped with fast line gear rod 11.
Be understandable that, more than about specific descriptions of the present utility model, only for the utility model being described and being not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
