Abstract
The utility model discloses a rotatable elevator. The rotatable elevator comprises a lifting ring, a nut, a gasket, a barrel, a hand wheel and bearings. The lifting ring comprises a ring body and a U-shaped rod, wherein the ring body and the U-shaped rod are mutually connected, the outer circle of the barrel is sleeved with the ring body, and two sets of bearings are arranged between the ring body and the barrel. The nut is screwed up and fixed to the top of the barrel, and the gasket is arranged between the nut and the ring body. The part, not provided with the lifting ring, of the outer circle of the barrel is connected with the hand wheel around the circumference of the barrel. The rotatable elevator is simple, ingenious and reasonable in structure, the barrel and the lifting ring of the elevator can relatively rotate on the basis of the guarantee of the structural strength of the elevator, even though the lifting ring on the upper portion is lifted, the barrel on the lower portion can still rotate to be connected with a drill rod, and then buckling and unbuckling of the drill rod are finished. The rotatable elevator is low in cost, convenient to manufacture, and suitable for being widely popularized and applied.
Description
Technical field
The utility model belongs to drilling project apparatus field, particularly a kind of for the device at drilling machine construction fast lifting drilling rod.
Background technology
Elevator is used for carrying a kind of instrument of hanging drilling tool while being geological core drilling lifting drilling tool.Elevator, progressively by manually developing into self-action and auto-manual system, does not need artificial dislodging on tower just can be connected or throw off with tool joint.Elevator has ball-jamming type, tiltedly asks formula and spring etc. multiple.Elevator mainly comprise top drop handle and the cylindrical shell of below, when engineering drilling lifting drilling tool, elevator cylindrical shell be rotatably connected with drill rod end joint and upper padlock tight, thereby make drilling rod be carried and drawing smoothly by elevator.Being fixed as one of the drop handle of existing elevator and cylindrical shell, when drop handle is when slinging state, the cylindrical shell of below is non-rotatable.Therefore each drilling rod is detained up and down, all drop handle must be unloaded down just and can be carried out from the state of slinging, and it is very inconvenient to operate.
Utility model content
For the existing above-mentioned defect of existing non-rotatable formula elevator, applicant is through Improvement, and a kind of simple in structure, easy to operate, rotary type elevator that operating efficiency is high is provided.
The technical solution of the utility model is as follows:
A kind of rotary type elevator, comprises drop handle, nut, packing ring, cylindrical shell, handwheel and bearing; Described drop handle comprises interconnective ring body and U-shaped bar, and described ring body is sleeved on the cylindrical of cylindrical shell, is provided with two groups of bearings between ring body and cylindrical shell; Nut screwing clamping is fixed on cylindrical shell top, between nut and ring body, is provided with packing ring; The position that drop handle is not installed on cylindrical shell cylindrical is connected with around the handwheel of cylindrical shell circumference.
Useful technique effect of the present utility model is:
The utility model is simple in structure, ingenious, reasonable, is guaranteeing, on the basis of elevator structural strength, to make rotate relative with drop handle of cylindrical shell of elevator, even if the drop handle of top is lifted, thereby the cylindrical shell of below also can rotate with drilling rod and be connected, and completes drilling rod and detains up and down.The utility model is with low cost, easily manufactured, is suitable for large application scope.
Advantage of the present utility model will provide in the description of specific embodiment part below, and part will become obviously from the following description, or recognize by practice of the present utility model.
Accompanying drawing explanation
Fig. 1 is stereogram of the present utility model.
Fig. 2 is sectional view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further.
As shown in Figure 1 and Figure 2, structure composition of the present utility model comprises drop handle 1, nut 2, packing ring 3, cylindrical shell 4, handwheel 5 and bearing 6.Drop handle 1 comprises interconnective ring body and U-shaped bar, and ring body is sleeved on the cylindrical of cylindrical shell 4, is provided with upper and lower two groups of bearings 6 between ring body and cylindrical shell 4.Nut 2 is tightened and is fixed on cylindrical shell 4 tops, and the cylindrical shell 4 between nut 2 and ring body is provided with packing ring 3, and packing ring 3 is fixed between nut 2 and ring body.The position that drop handle 1 is not installed on cylindrical shell 4 cylindricals was connected with handwheel 5, and handwheel 5 is ring-type, around cylindrical shell 4 one weeks.The utility model makes the cylindrical shell 4 can rotation relative to drop handle 1 by the effect of bearing 6, even if drop handle 1 is lifted, also can promotes handwheel 5 cylindrical shell 4 is rotated, and the screw thread of rotation rear cylinder body 4 belows is connected with tool joint, and then has locked the button up and down of drilling rod.Nut 2 and packing ring 3 guarantee that drop handle 1 can not deviate from from cylindrical shell 4 tops.
Above-described is only preferred embodiment of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate under the prerequisite that does not depart from basic conception of the present utility model, within all should thinking and being included in protection domain of the present utility model.
