Abstract
Present invention discloses a oil well port hydraulic lifting device. It includes overhead I-section steel slideway, travelling crab and hanger, hanger having slinger assembly and steel wire rope, symmetric installed hydraulic cylinders on hanger, a hydraulic cabinet with oil inlet and oil return port and control handle, hydraulic pipeline connected between hydraulic cabinet and hydraulic cylinder and behavioral between hydraulic cabinet and travelling crab driving wheel, speeding-up pulley block, slinger assembly, and brake valve for controlling hydraulic cylinder. Said invention has simple structure, compactness, safety and reliable.
Description
Technical field
The present invention relates to promote particularly a kind of cellar hydraulic lifting apparatus that mobile operating is used when being adapted at carrying out in the oil field development preventer and installing.
Background technology
At present, when the oil well mouth carried out the preventer installation exercise, in order to guarantee safety, its power of used lifting appliance all adopted fire-proof motor.Therefore, the structure of this lifting appliance is to be furnished with sport car and suspension bracket on an i iron slideway, and suspension bracket is provided with suspension ring assembly and wire rope, lifting and horizontal drive sport car all are fire-proof motors.The shortcoming that this device exists is that volume is big, manipulation is complicated, cost is high.
Summary of the invention
The objective of the invention is to design a kind of safe and reliable, volume is little, manoeuvrable, cellar hydraulic lifting apparatus that cost is low.
Task of the present invention is finished as follows, it includes built on stilts i iron slideway, sport car and suspension bracket, suspension ring assembly and wire rope are arranged on the suspension bracket, it is characterized in that: parallelly on suspension bracket be symmetrically installed with two hydraulic cylinders, have a hydraulic cabinet at suspension bracket, the oil-in and oil return opening and the control crank that are communicated with Hydraulic Station are arranged on the hydraulic cabinet, between hydraulic cabinet and each hydraulic cylinder, between hydraulic cabinet and sport car driving wheel, be connected with fluid pressure line respectively, the drive rod front end of each hydraulic cylinder is connected on the movable pulley of a speedup assembly pulley, the wire rope other end that the suspension ring assembly connects is later walked around a breast wheel through fixed pulley and movable pulley and is fixed on the movable pulley through transition wheel, is respectively equipped with the brake valve of control hydraulic cylinder action on the fluid pressure line of hydraulic cylinder.
The advantage that the present invention has is simple in structure, volume is little, work is flexible, safe and reliable.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a lateral view of the present invention.
The specific embodiment
The present invention includes a built on stilts i iron slideway 6 and sport car and suspension bracket 11, on the suspension bracket to having suspension ring assembly 1 and wire rope 4, improvements are that parallel symmetry is equipped with two hydraulic cylinders 12 side by side on suspension bracket, be provided with a hydraulic cabinet 16 in next side of suspension bracket, the oil-in 17 and the oil return opening 18 that are communicated with Hydraulic Station are arranged on the hydraulic cabinet, and control crank 15, between hydraulic cabinet and each hydraulic cylinder, between the driving wheel of hydraulic cabinet and sport car, be connected with fluid pressure line 13 respectively.On each hydraulic cylinder, be respectively equipped with hydraulic manifold block 14, each Driven by Hydraulic Cylinder bar front end is connected on the movable pulley 5 of a speedup assembly pulley, the wire rope other end that is connected with the suspension ring assembly is later walked around a breast wheel 3 again through fixed pulley 2 and movable pulley upside, is fixed on the movable pulley through transition wheel 7.Between hydraulic cylinder and fluid pressure line, be respectively equipped with the brake valve 10 of control hydraulic cylinder action, when hydraulic oil disconnects, can make the former lifting of resting on of weight safety position.
When on the oil well mouth, carrying out installation exercise, as long as preventer is installed on the derrick track, advance and retreat by the operating hydraulically operated control sport car of control crank driving wheel 8 and driven pulley 9, the flexible movable pulley that drives in the speedup assembly pulley of operating hydraulically operated control Driven by Hydraulic Cylinder bar moves forward and backward simultaneously, make wire rope drive when each pulley rotates hang object and move up and down certain height, reach the purpose of safety lifting moving heavy object.Because of its power all adopts all-hydraulic control, can reach the fireproof purpose fully; Adopt the assembly pulley of three multiplication speed, the effect of speedup in the time that lifting can being reached.That this device has is simple in structure, volume is little, manoeuvrable, safe in utilization, advantage that cost is low.
