Abstract
The utility model provides a fast plugging guide rail for the top drive device of a petroleum drilling machine, including a frame plate (1), a lock pin (2), a lower joint assembly, a fixed pin (4), a hook plate (5), a guide rail pin (6), and an upper joint assembly (7), with the lower joint assembly (3), the hook plate (5) and the upper joint assembly (7) being connected in turn, the hook plate (5) being arranged inside the frame plate (1), the guide rail pin (6) being connected to the frame plate (1) through the lock pin (2), and the hook plate (5) being arranged with the fixed pin (4). Because the load on the front, back and lateral bends of the guide rail is borne by the frame plate of the plugging structure, the stress on the guide rail pin is improved to prevent it from breaking or loosening, thereby greatly enhancing the safety and reliability of the entire top drive system. The utility model is advantageous to spread the top drive device on a wide scale.
Description
Technical field
The utility model belongs to petroleum and natural gas drilling equipment field, is the single-rail assembly of oil-well rig top-drive drilling, specifically, is the fast-spliced guide rail of a kind of top driving device of oil rig.
Background technology
Top-drive drilling is suspended on the tourist bus or hook of rig, slides up and down along guide rail in when work, and guide rail is born shackle and the reaction torque when creeping into, and therefore, guide rail is one of vitals of top driving device.
At present the guide rail that uses adopt a kind of single ears joint butt joint syndeton it form by critical pieces such as monaural joint, back pin, preceding pin, lock pin, ears joints.When installing at the scene, needing will go up earlier the joint guide rail vertically slings, following joint guide rail lies against on the offshore boring island, connect this moment and upward save the monaural joint of guide rail and the ears joint of following joint guide rail, penetrate preceding pin, after carrying tourist bus to two joint guide rail on then and all being positioned at vertical position, align the back pin-and-hole, penetrate the back pin, and lock pin is installed with fixing back pin.
Former guide rail exists some problems in installing and using process: 1. manually align pin-and-hole when installing and the plug-in mounting lock pin is very difficult, made guide rail install to have taken the top to drive 1/3 even longer time of installation.2. owing to adopt double-pin to connect, make guide rail when the bending of front and back, guide pins is directly born shearing force, so easy disconnected the taking off of guide pins, and has fixing difficult problem simultaneously, takes off and will jeopardize the safety of top drive system in case break.
Summary of the invention
The purpose of this utility model is to provide a kind of top driving device of oil rig fast-spliced guide rail, single ears of having cancelled two ends connect, newly designed a kind of in light weight, fast-spliced connected mode convenient and swift, simple to operate of pegging graft, the guide rail auxiliary connection has automatic hanging mechanisms, does not need manual intervention can finish the grafting of two joint guide rails.Only need the fixedly connected pair of pin after the grafting.
The utility model is achieved in that and comprises frame plate, lock pin, lower contact assembly, steady pin, hook plate, guide pins, top connection assembly, lower contact assembly, hook plate, top connection assembly connect successively, hook plate places in the frame plate, guide pins is connected with frame plate by lock pin, and hook plate is provided with steady pin.
Auxiliary connection mainly comprises lock pin, lower contact assembly (comprising frame plate, hook plate etc.) and guide pins, top connection assembly (comprising steady pin etc.) etc.Auxiliary connection has hanging mechanisms, and a last joint guide rail can save next the grafting that two joint guide rails were hung up and finished to guide rail.
After pegging graft, auxiliary connection only need a pin to fix.
Plug-in connection comprises a tower structure, the crooked and perverted load in front and back during guide rail work, and major part is born by frame plate, and guide pins does not stress.
The utility model distinguishing feature is: 1. in light weight, peg graft convenient and swiftly, simple to operate, safe in utilization, easy to process, and can significantly reduce manually-operated at the scene in the installation process, shorten the set-up time, improve field erected operating efficiency.2. in use, crooked and perverted load before and after the guide rail, frame plate 1 by connected structure bears, improved the stressing conditions of guide pins 6, avoid it to produce disconnected danger of taking off, the safety and the reliability of whole top drive system have been improved to a great extent, for the popularization on a large scale of top driving device provides convenience.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
As shown in drawings, comprise frame plate 1, lock pin 2, lower contact assembly 3, steady pin 4, hook plate 5, guide pins 6, top connection assembly 7, lower contact assembly 3, hook plate 5, top connection assembly 7 connect successively, hook plate 5 places in the frame plate 1, guide pins 6 is connected with frame plate 1 by lock pin 2, and hook plate 5 is provided with steady pin 4.
Auxiliary connection by the guide rail rapid plug-in mechanism mainly is made up of lock pin 2, lower contact assembly 3 (comprising frame plate 1, hook plate 5 etc.) and guide pins 6, top connection assembly 7 (comprising steady pin 4 etc.).Lower contact assembly 3 and top connection assembly 7 constitute the core of guide rail auxiliary connection, are welded on the two ends of single-unit guide rail respectively.During on-the-spot the installation, needing will go up earlier the joint guide rail vertically slings, following joint guide rail lies against on the offshore boring island, align joint guide rail lower contact assembly 3 and following joint guide rail top connection assembly 7, connection hook plate 5 and steady pin 4 are also sling, be promoted to and transfer tourist bus after two joint guide rails all are positioned at vertical position, because deadweight, lower contact assembly 3 will be packed in the top connection assembly 7 that has frame construction automatically, do not need manual intervention promptly to finish autopatching, this moment, up and down the pin-and-hole of adapter assembly can align automatically, and guide pins 6 is inserted pin-and-holes just can fixedly connected pair, inserts lock pin 2 fixed guide pins 6 then.
Auxiliary connection has hanging mechanisms, and a last joint guide rail can save next the grafting that two joint guide rails were hung up and finished to guide rail.
After pegging graft, auxiliary connection only need a pin to fix.
Plug-in connection comprises a tower structure, the crooked and perverted load in front and back during guide rail work, and major part is born by frame plate 1, and guide pins 6 does not stress.
