Abstract
The utility model relates to the technique of oil drilling and production equipment, in particular to a telescopic mechanism of a headframe which is suitable for three cased headframes which are formed by a headframe upper body, a headframe middle body and a headframe lower body, is provided with a pair of telescopic hydraulic cylinders which synchronously work and are mounted between the hearframe lower body and the headframe middle body, and is further provided with a cable wire-pulley lifting mechanism which is formed by a pulley which is mounted on the headframe middle body and cable wires which are around the rear both ends of the pulley and are respectively mounted on the headframe lower body and the headframe upper body. Since the telescopic mechanism is provided with the headframe middle body which drives the cable wire-pulley lifting mechanism to work through the protrusion and the contraction of the telescopic hydraulic cylinders, thereby simultaneously driving the headframe upper body to extend out and retract. The utility model has the advantages of simple structure, low cost and high telescopic operation cost.
Description
Technical field
The utility model relates to the oil drilling and extracting equipment technology, specifically is a kind of derrick telescoping mechanism.
Background technology
Derrick is one of important composition parts of oil-well rig, in the drilling well manufacturing process, be mainly used in erecting equipment and instruments such as laying and hang overhead traveling crane, tourist bus, hook, lay and hang mud circulation equipment and instruments such as standpipe, water tap, hose, bear make a trip, setting of casing, load that salvaging and other operations produced, the height and the space that make a trip and deposit the thribble operation are provided, handle drillng operations such as down-hole accident.
Along with improving constantly to oil-well rig boring tower requirement for height and performance requirement, truck-mounted drill rig, pull drilling derrick adopts by the derrick upper body more, body in the derrick, derrick lower body three joint suits constitute the structure of derrick main body, during transportation, the three joint derricks that are sleeved on together are placed in carrier loader or the trailer chassis and transport with car, during on-the-spot the installation, the three joint derricks that will be sleeved on earlier together by two multistage raising cylinders of double actings change spoke that are connected on carrier loader crossbeam and the derrick lower body erect, and stretch out and the stretching out with withdrawal of withdrawal and middle body of derrick upper body are all adopted independent mechanical structure or fluid pressure type structure stretch mode.This derrick stretching structure when adopting the fluid pressure type structure, needs to adopt four hydraulic cylinders, cost height, complicated operation; When adopting mechanical structure, drive hook by winch power body in derrick upper body, the derrick is pulled out respectively, two winch power need be arranged, complex structure, the cost height, the flexible operating efficiency of derrick is low.
Summary of the invention
The purpose of this utility model provide a kind of be used for three joint suit derricks simple in structure, cost is low, the flexible high derrick telescoping mechanism of operating efficiency of derrick.
Technical solutions of the utility model are: a kind of derrick telescoping mechanism, be applicable to the three joint suit derricks of forming by body, derrick lower body in derrick upper body, the derrick, it is characterized in that: have and be installed in derrick lower body and the derrick a pair of telescopic hydraulic cylinder of synchronous working between the body, have also that two ends are separately fixed at the wire rope-pulley hoisting mechanism that constitutes on derrick lower body and the derrick upper body after the pulley on the body and wire rope are walked around pulley in the derrick by being installed in.
Operating principle: three joint suit derricks are transported to behind the well site by being connected two double actings on carrier loader crossbeam and the derrick lower body and become the multistage raising cylinders of spoke and realize being sleeved on erecting of together three joint derricks, in the derrick body to stretch out with withdrawing be to realize by being installed in a pair of telescopic hydraulic cylinder of synchronousing working between the body in derrick lower body and the derrick.Stretch out and the withdrawal of derrick upper body is along with stretching out with withdrawal of body in the derrick realized simultaneously by wire rope-pulley hoisting mechanism, promptly in the process that body stretches out in derrick, drives wire rope-pulley hoisting mechanism work simultaneously, drives the derrick upper body and stretches out simultaneously; In derrick in the process of body withdrawal, deadweight and wire rope-pulley hoisting mechanism by the derrick upper body are withdrawn the derrick upper body simultaneously.
The utility model is owing to have body in the derrick and stretch out in the process with withdrawal by telescopic hydraulic cylinder, can drive wire rope-pulley hoisting mechanism work, thereby driving the derrick upper body simultaneously stretches out and the design feature of withdrawing, make the utlity model has simple in structure, cost is low, the derrick high advantage of operating efficiency of stretching.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the lateral view of Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, three joint suit derrick main bodys are made up of body 2, derrick upper body 3 in derrick lower body 1, the derrick, and load carrier 10,11 is realized the support to body 2, derrick upper body 3 in the derrick that stretches out respectively.The derrick telescoping mechanism comprises that two ends are separately fixed at a pair of telescopic hydraulic cylinder 4,5 of the synchronous working on body 2 tops in derrick lower body 1 bottom and the derrick and are symmetrical arranged and two wire rope-pulley hoisting mechanism that structure is identical, wire rope-pulley hoisting mechanism by the pulley 6 that is fixed on body 2 upper ends in the derrick, the wire rope 9 walked around on the otic placode 8 of otic placode 7 that pulley 6 two ends are separately fixed at derrick lower body 1 upper end, 3 lower ends, derrick upper body forms.
The course of work of derrick telescoping mechanism:
The stretching out of body 2, derrick upper body 3 in the derrick: refuel for telescopic hydraulic cylinder 4,5, fluid cylinder stretches out, and drives under the effect of thrust that body 2 protrudes upward in the derrick, requires to keep that body 2 slowly rises in the derrick, when approaching putting in place, slows down the speed of stretching out.Treating in the derrick that body 2 rises to is higher than on the derrick lower body 1 about the 50～100mm of carrier bar position, after the normal ejection of the carrier block of load carrier 10, stop oil circuit and refuel, body 2 is slowly transferred in the derrick, and the complete seat of carrier block that makes load carrier 10 is on the carrier bar of derrick lower body 1.Treat to close after the release oil circuit switch of hydraulic cylinder 4,5.In the process that body 2 stretches out in derrick, drive two wire rope-pulley hoisting mechanisms and work simultaneously, stretch out simultaneously thereby drive derrick upper body 3,11 pairs of derrick upper bodies of load carrier 3 realize supporting.
The withdrawal of body 2, derrick upper body 3 in the derrick: refuel for telescopic hydraulic cylinder 4,5, body 2 continues to protrude upward about 250mm in the derrick, after the carrier block for the treatment of the load carrier 10 of body 2 in the derrick is withdrawn fully, stop to refuel, and make extending cylinder 4,5 releases, body 2 is slowly transferred in the derrick, and steadily withdrawal puts in place.Drive simultaneously wire rope-pulley hoisting mechanism work in derrick in the process of body 2 withdrawals again, derrick upper body 3 continues to protrude upward about 250mm simultaneously, and after load carrier 11 carrier blocks were withdrawn fully, slowly transferred derrick upper body 3, and steadily withdrawal puts in place.
