Abstract
The utility model relates to a folding hydraulic lifter used for lifting a petroleum drilling platform. The utility model is composed of an upper and a lower guide rail frames, hydraulic controllers, lifting baskets, a pulley block component, wherein an upper and a lower guide rail are connected by a connecting component to form folding guide rain frames. The bottoms of the upper and the lower guide rail frames are provided with the adjustable speed hydraulic controllers. The middle parts of the upper and the lower guide rails are provided with the pulley block component with increasable distance. The side surfaces of the upper and the lower guide rails are provided with the lifting baskets. The utility model has the advantages of novel design, reasonable and compact structure, stable running, high safety and reliability and convenient transportation and maintenance. The utility model can be widely matched with a driller to reduce workers' working intensity.
Description
The utility model is a kind of folding type hydraulic gig that promotes operation that is applicable on the petroleum drilling platform, and itself and oil machine are supporting, are used for from ground to the manned and loading operation between drilling platform.
Relevant by retrieval patent documentation still finds no the gig identical with the utility model structure.In the oil field, because the platform of part deep drilling rig apart from ground 7.5 meters-10 meters, it is extremely inconvenient to make driller carry object, sleety weather particularly, easily make driller slip and have an accident, at present the part rig uses two kinds in ramp type elevator and hydraulic up-down machine, and the former combines with winch for tilting guide rail bracket, simple in structure, volume is big, and floor area is big, installation and transportation inconvenience, and be that pure electrical control drives, braking, electromagnetic brake can not satisfy oil drilling field requirement of explosion; And the latter is a vertical type, transports object by lifting on the fluid cylinder, though volume is less relatively, its fluid cylinder is generally single-stage or multistage cylinder, and stroke is oversize, and to make very inconvenient in addition, and less stable is so progressively eliminated.
The electricity piece that the purpose of this utility model provides on a kind of complete machine adopts flame-proof type, and is safe and reliable, transportation easy-to-install folding type hydraulic gig.
Technology technical solution of the present utility model is: the folding type hydraulic gig, constitute by up and down guide rail bracket, hydraulic control device, hand basket, tractive pulley element assembling, and it is characterized in that: go up lower guideway and constitute collapsible guide rail bracket with coupling component; Hydraulic control device by load variations scalable rising or falling speed is housed in the bottom of guide rail bracket up and down; But the tractive pulley element of speedup increment is housed at last lower guideway middle part, hand basket is housed in guide rail side up and down.
In the folding attachment of guide rail bracket up and down inserted limiting stopper and orienting lug are housed, and with the bearing pin fastening connection of guide rail bracket up and down.A motor is housed in the bottom of hydraulic control device, connect with coupler and Variable plunger pump, on the guide rail bracket at an upper portion thereof fuel tank is housed, on the valve plate of guide rail bracket, balance cock, flame proof electromagnetic valve, overflow net, compression indicator are housed, interconnect with high pressure line, the defeated people of valve plate and mouth respectively with hydraulic actuating cylinder, fuel tank, stop up pump and link to each other.Idler wheel mechanism is equipped with in side at netted hand basket, in the both sides of hand basket supporting plate is housed, and steel rope is housed on the supporting plate.The fixed pulley of tractive pulley element is packed in the below of lower guideway frame, the suspension type hydraulic actuating cylinder that oscillating bearing connects is housed at the middle part of upper rail frame, movable pulley thereunder is housed, steel rope top is packed on the movable pulley, after twining the movable and fixed pulley group, be suspended on the pulley on guide rail bracket top, terminal is packed on the supporting plate of hand basket.Steel rope between the movable and fixed pulley group is established two strands of left-right symmetric.
Behind the main power source of connecting the folding type hydraulic gig, the next amount all can be controlled lifting button on hand basket, drilling platform, makes the driven by motor plunger pump, the modulated pressure device, make hydraulic actuating cylinder and the oscilaltion of rod end bonded assembly running block, drive steel rope and move, realize the lifting of hand basket.
The utility model has the advantages that modern design, compact conformation is reasonable, owing to be provided with coupling component on guide rail, makes upper and lower guide rail collapsible, and installation and transportation are convenient; Limiting stopper that is provided with in the coupling component and orienting lug operate steadily pulley up and down; Owing between the movable and fixed pulley group, be provided with left-right symmetric two strand steel wire ropes, but many times of increments, and its dipping and heaving speed improves many times, and the fluid cylinder stroke is greatly reduced, and avoids multistage fluid cylinder to make difficulty, reduces machine volume and cost; Owing in hydraulic control device, be provided with Variable plunger pump; can change running velocity; be provided with the weighing apparatus valve; make under the weight and keep steady, lock safe and reliablely, the by pass valve that is provided with has overload protective function; safe and reliable; easy to maintenance, in extensively being matched in, deep drilling rig uses, and greatly alleviates workman's operation intensity.
