Abstract
The utility model provides a lifting device applicable to oil field well drilling and repairing, in particular to a counting ground sheave pulley. The counting ground sheave pulley comprises a pulley, a pulley shaft, lateral plates and a lifting ring, wherein two lateral plates are connected into a frame through fastening bolts, the lifting ring is installed on the top of the frame, the pulley is fixedly installed on the middle portion of the pulley shaft, two ends of the pulley shaft are installed in shaft holes in the middle portions of the two lateral plates through bearings, and one end of the pulley shaft is provided with a counter. The counting ground sheave pulley has rational structure, the length of a cable passing through the pulley, namely the lifting or descendent height of workpieces can be conveniently and accurately measured through the pulley shaft rotation circles recorded by the counter, and the counting ground sheave pulley is particularly applicable to lifting operation of underground equipment.
Description
Technical field
The utility model relates to a kind of jacking system that is used for oil drilling, well workover, particularly a kind of counting ground coaster.
Background technology
In oil drilling, well workover process, because the lift work number of times is comparatively frequent, adjustable height height, equipment weigh, and in order to reduce labor intensity, to increase work efficiency, adopt the ground coaster usually.The ground coaster that uses is made up of pulley, sheave shaft, side plate and enhancing ring usually at present; Biside plate constitutes framework by tie bolt, and enhancing ring is equipped with at the top of framework; Pulley sleeve places on the wheel shaft and is loaded in the framework.During use, the ground coaster hangs on the workpiece by enhancing ring, twines cable on pulley, and an end of cable links to each other with the workpiece of required lifting, and its other end draws by manpower or motor, thereby workpiece is carried out lift work.Existing ground coaster, though tool is laborsaving, improve work efficiency, change the function of power thrusts, can not calculate cable the length by pulley be the height that workpiece is raised or descends, especially be unfavorable for the lifting operation of underground equipment.
The utility model content
For overcoming the deficiencies in the prior art part, the utility model provides a kind of counting rational in infrastructure electricity coaster, can calculate the height that workpiece is raised or descends easily and accurately, is specially adapted to the lift work of underground equipment.
The technical scheme that its technical matters that solves the utility model adopts is: it comprises pulley, sheave shaft, side plate and enhancing ring; Biside plate connects into framework by binding bolt, and enhancing ring is loaded on the top dress of framework; It is characterized in that: pulley is loaded on the middle part of sheave shaft regularly, and the two ends of sheave shaft are loaded in the axis hole at biside plate middle part by bearing; End at sheave shaft is equipped with counting machine.
The beneficial effects of the utility model are: it is rational in infrastructure, sheave shaft by the counting machine record rotates the number of turns, can calculate the length of cable by pulley easily and accurately, i.e. the workpiece height that is raised or descends is specially adapted to the lift work of underground equipment.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 is that enhancing ring, 2 is that side plate, 3 is that pulley, 4 is that sheave shaft, 5 is that end cap, 6 is that binding bolt, 7 is that counting machine, 8 is that bearing, 9 is a spline.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The utility model comprises pulley 3, sheave shaft 4, side plate 2 and enhancing ring 1; Biside plate 2 connects into framework by several binding bolts 6, and enhancing ring 1 is loaded on the top of framework; Pulley 3 is loaded on the middle part of sheave shaft 4 regularly by spline 9, and the two ends of sheave shaft 4 are loaded in the axis hole at biside plate 2 middle parts by bearing 8, and adopts end cap 5 sealings; End at sheave shaft 4 is equipped with counting machine 7.
During work, the utility model hangs on the workpiece of required lifting by enhancing ring 1, on pulley 3, twine cable, one end of cable links to each other with workpiece, its other end draws by manpower or motor, thereby workpiece is carried out lift work. and the sheave shaft 4 by counting machine 7 records rotates the number of turns, can calculate the length of cable by pulley 3 easily and accurately, be the height that workpiece is raised or descends, be specially adapted to the lift work of underground equipment.
