Description
Technical field
The present invention relates to a kind of cat road of oil-well rig, particularly relate to a kind of drilling rod from the oil-well rig cat road promoted.
Background technology
China's rig, in drilling process, to upper and lower drilling rod, by manual operation, need be coordinated the compressed air hoist on rig floor and cat road, has been come from the ground rack for rods of Mao Dao side by the mode of drawing, dragging.For the benefit of operate, cat road and rack for rods are designed to equal height, are placed in ground, and drilling rod is advanced cat road from rack for rods by workman, and drilling rod pushes back rack for rods after finishing using again.The domestic afterwards technology (see patent CN201220712048) also researching and developing " a kind of fortune upper and lower Mao Dao mechanism of drilling tool ", this technology solves the unartificial mode in conventional individual well cat road drilling rod upper and lower cat road, but the problem in drilling rod upper and lower cat road when can not solve petroleum drilling machine drill cluster well.Rig, when boring cluster well, has often bored a bite well, can continue to creep into by bulk migration to neighbouring next well location nearby, can carry out follow-up work to the wellhead assembly of high about about 600mm or 1.2 meter of the well head installation of having bored in order to oil production equipment simultaneously.In order to the wellhead assembly just installed can not be encountered when being beneficial to rig whole translation, cluster well cat road is generally designed to gate-type overhead type, to get out of the way wellhead assembly, the cat road height that its aspect ratio bores individual well wants high, the ground rack for rods of the both sides, problem Shi Mao road of bringing like this will the height of a low wellhead assembly compared with cat road work plane, calculate with drilling rod long 9m, a 22kg/m, at this moment upper and lower drilling rod is very difficult by a dead lift, wastes time and energy.Therefore need to design a kind of novel cat road, realize by drilling rod automatic lifting to cat road work plane, automatically drilling rod can be transferred to again the function on rack for rods.
Summary of the invention
The object of the present invention is to provide a kind of Hoisting System by being made up of pulley system, risen to by drilling rod on rack for rods lower than cat road work plane on cat road, the oil-well rig cat road of oneself lifting of drilling rod that rack for rods gets on put back to again by drilling rod by this system after finishing using.
Technical scheme of the present invention is: it comprises cat road main body and is fixedly connected on the Hoisting System of main body both sides, cat road, described cat road main body is by the support system below cat road main body, cat road work plane, the winch one that cat road work plane is arranged, winch two, buffer and peripheral components ladder, railing assembly is formed, described Hoisting System comprises fixed pulley, otic placode, wire rope, lifting truck, running block and lift rail and dolly locking device, lift rail and dolly locking device, fixed pulley is symmetricly set on main body both sides, cat road, wire rope one end is walked around running block and is fixed on otic placode, the other end is fixed on winch one, on winch two cylinder, described lifting truck is drawn by winch one or winch two and slides up and down along lift rail.
Described support system by supporting horse, link, strut, hound formed by pinned connection.
Described cat road work plane is in aggregates by engaging lug plate, pinned connection by slideway one, slideway two.
Described cat road also comprises air-channel system, this air-channel system includes compressed air hoist, foot valve, stroke valve, two-position three-way and the gate shuttle valve of being with break brake function, described stroke valve is arranged in running block pull bar both sides, pull bar is fixed with slide block, and described foot valve is arranged on winch one, winch two base.
The Hoisting System of the present invention by being made up of pulley system, rises to the drilling rod on the rack for rods lower than cat road work plane on cat road, and drilling rod is put back to rack for rods by this system again after finishing using and got on.Structure of the present invention is simple, time saving and energy saving, working stability, safe and reliable.

Detailed description of the invention
Drilling rod is from the oil-well rig cat road promoted, and it comprises cat road main body and is fixedly connected on the Hoisting System 14 of main body both sides, cat road, and described cat road main body is by the support system below cat road main body, cat road work plane, the winch 1 that cat road work plane is arranged, winch 2 10, buffer 11 and peripheral components ladder 5, railing assembly 6 is formed, the tower structure of described cat road body design component block assembling, and each piecemeal is connected by bearing pin 13, described winch 1, winch 2 10, wherein one adds the compressed air hoist of service brake for parking brake, and one adds air-cut-off break compressed air hoist for parking brake, and described Hoisting System 14 comprises fixed pulley 16, otic placode 17, wire rope 18, lifting truck, running block 19 and lift rail and dolly locking device 20, lift rail and dolly locking device 20, fixed pulley 16 is symmetricly set on main body both sides, cat road, and wire rope 18 one end is walked around running block 19 and is fixed on otic placode 17, and the other end is fixed on winch 1, on winch 2 10 cylinder, described lifting truck is slided up and down along lift rail by winch 1 or winch 2 10 traction.
Described support system by supporting horse, link, strut 7, hound 8 be formed by connecting by bearing pin 13.
Described cat road work plane connects in aggregates by slideway 1, slideway 2 15 by connection otic placode 3, bearing pin 13.
Operate to prevent crossing in lifting process, namely after drilling rod is promoted to work plane, winch still does enhancing action damage lift rail and cat road main body, and devise a kind of by installing the air-channel system of stroke valve as stopping means, crossing when preventing drilling rod from promoting operates.Described cat road also comprises air-channel system, this air-channel system includes compressed air hoist, foot valve 25, stroke valve 28, two-position three-way 26 and the gate shuttle valve 29 of being with break brake function, described stroke valve 28 is arranged in running block 19 pull bar both sides, pull bar is fixed with slide block, and described foot valve 25 is arranged on winch 1, winch 2 10 base.When lifting truck arrive the peak, the drilling rod that arrange be promoted to cat road work plane complete the lifting of drilling rod time, slide block touches stroke valve, and winch 1 or the main gas circuit of winch 2 10 are cut off, winch brake and quitting work.When needs drilling rod is transferred, only need to step on the foot valve 25 be arranged on winch 1 or winch 2 10 base, then operate winch 1 or work transferred by winch 2 10.
The drilling rod improvement stage: first non-lifting side lifting truck is locked before use, winch 1 or winch 2 10 do lifting work, the pulling force that winch provides converts the pulling force of lifting truck in lift rail to by the pulley system be arranged in below cat road work plane, lifting truck vertically rises along lift rail, thus promotes drilling rod; Transfer the stage: when drilling rod finish the work to put back to rack for rods time, transfer work by winch, lifting truck declines along lift rail, and the drilling rod be placed on dolly completes transfers action.
