Abstract

The utility model belongs to a hoisting device, mainly relating to a hoister for deep wells, and the utility model comprises a machine frame, a winding machine, a pulley block and a wire rope for connecting. The utility model is characterized in that a movable pulley in the pulley block is hinged with the elevating beam of an elevator, and the elevating beam forms a shape like the Chinese character 'ba'. The utility model can be widely used for elevating and hoisting diving pumps, deepwell pumps and drilling machinery, cleaning sludge for the deep wells, stabilizing foundation, etc. The utility model has high work efficiency, reliable braking performance and reliable and flexible hoisting process.

Description

Gig

The utility model belongs to lifting means, relates generally to the deep-well gig.

Prior art is to lifting, the lifting of diving pump, deep well pump and drilling machinery, the deep-well desilting, operations such as foundation stabilization are all adopted bottle gouard moved by hands, electric block, line mill etc. to carry to draw equipment, inefficiency, labour intensity height, particularly in lifting process, carried thing and often come off poor safety performance from lifting means.

The purpose of this utility model provides a kind of high efficiency, labour intensity is low, lifting process is safe and reliable deep-well gig.

The utility model comprises frame, winch and assembly pulley and connection steel rope, it is characterized in that the bale handle of movable pulley and elevator is hinged in the assembly pulley, and bale handle is splayed.

The two side arms of the bale handle of the utility model elevator is provided with symmetrical holes, U type or circular ring type move about the ring with the bale handle two side arms on the hole hinged.The bale handle two ends all connect the ring that moves about, and the ring that moves about connects with middle round-meshed clamping plate.The two ends of clamping plate are fluted, and the ring that moves about at bale handle two ends snaps in the groove of clamping plate.

The utlity model has compact conformation, easy to assemble, in light weight, convenient transportation, lifting is steady, high efficiency; Adopted the two brake measures of self-locking type reductor and electromagnetic brake, winch was stopped operating in moment, deceleration and stopping performance is reliable; Use elevator, can move about by adjusting and encircle and clamping plate, the well class that adapts to different size promotes, and can prevent that the lifting thing in the lifting process from coming off, and carries and draws process safety, flexible.A 150QJ-96/16 type diving pump is installed, the utility model needs 3 humans to finish erection work in 4 hours, saves about 10 hours man-hours than bottle gouard moved by hands, saves about 4 hours than electric block, compare with strand mill and to save about 8 hours man-hours, and greatly reduce labour intensity.

The utility model is described in further detail below in conjunction with accompanying drawing:

Accompanying drawing is the structural representation of the utility model embodiment;

Among the figure, be the fixing fixed pulley in top of the frame 1 of A type, winch 2 is fixed on the chassis of frame 1, and the fixed pulley on the winch 2 is formed assembly pulley 3 with the fixed pulley on frame 1 top and by the movable pulley that steel rope 4 is connected in series.Elevator 5 is hinged by the axle that moves about with movable pulley.During work, earlier promoting in the circular hole that well casing is placed on clamping plate 8, by the bolt on the clamping plate well casing is fixed, and handle is hinged on, and the moving about ring 7 in the circular hole is placed in the groove of clamping plate 8 on the bale handle 6, start double-speed motor, by electromagnetic brake, reductor, the rotation of drive reel, drive elevator 5 by the movable pulley in the assembly pulley 3 and rise, thereby can elevate the well casing pulsation-free.The circular hole of symmetry is set on the two side arms of bale handle 6, can be 2,4,6 or above even number, to adapt to the distance of regulating between the clamping plate.

In use of the present utility model, if the machine room height deficiency can reduce bracket height, strengthen the chassis of frame, frame is placed on the roof, working process is with above-mentioned embodiment.
