Abstract
The utility model relates to a two pneumatic cylinders play to rise rig, it includes derrick and base, be equipped with the derrick lug on the derrick, the upper strata of base is equipped with base lug, first derrick supporting seat and second derrick supporting seat, and be equipped with in the lower floor of base and risen the hydro -cylinder, play to rise the hydro -cylinder and link to each other through the lower floor of pivot with the base, be equipped with the bracing piece between the upper strata of base and lower floor, the both ends of bracing piece articulate respectively and between the upper strata of base and the lower floor. The utility model discloses the simplification derrick structure that more traditional oil -well rig can be great, simple to operate improves the installation effectiveness, and traditional rig is playing when rising must be by the driller's operation that possess corresponding qualification, and the driller takes to carve and is paying close attention to hook load, and hook hoist speed isoparametric is professional higher. Furthermore, the utility model discloses simple structure, simple to operate, it is easy to rise, improves the effect and is showing.
Description
Technical field
This utility model belongs to petroleum gas drilling industry, hoists rig particularly to a kind of simple in construction, double hydraulic cylinder easy for installation.
Background technology
In oil-well rig, hoisting system is one of important ingredient, it is necessary to can be only achieved vertical duty by hoisting system. As shown in Figure 1, conventional petroleum rig hoisting system is made up of the freely-supported pulley 5 connected on otic placode 2, man-like shelf 3, big lifting rope 4, derrick on winch 1, base, the boom sheave 6 on derrick, traveling system 7, the big rope 8 of derrick drilling well, when conventional petroleum rig hoists, power is provided to pull the big rope 8 of derrick drilling well to shrink by winch 1, fast line shortening drives traveling system 7 to up simultaneously, traveling system 7 is because linking together with big lifting rope 4, so big lifting rope 4 also can draw high therewith. So by the big rope 8 of derrick drilling well and the big lifting rope 4 pulling force to derrick, make derrick lifting. After derrick lifting completes, derrick can be limited and immovable. Winch 1 continues the big rope 8 of derrick drilling well is applied pulling force, and on the connection otic placode 2 that big lifting rope 4 one sections is connected on base, therefore base can hoist.
By the above step that hoists, it has been found that tradition hoists drill configuration complexity, structure very complicated, installing and dismounting difficulty, the manual work of demand measures greatly. And big lifting rope belongs to consumable goods, must change after certain number of times that hoists, virtually add drilling cost; Additionally conventional petroleum rig must be operated by the driller having corresponding qualification in the process of hoisting, and must note hook load, hook speed and the safe distance bottom hoist last hook and crownblock beam in the process the moment. The process that hoists is higher to the professional requirement of driller. Therefore, when guaranteeing normally to hoist, simplifying structure, easy to operate, increase work efficiency, saving manpower becomes the emphasis of design new petroleum drill machine.
Summary of the invention
For prior art Problems existing, this utility model provides a kind of double hydraulic cylinder to hoist rig, it is possible to simplifies device structure, simplify procedures, improves work efficiency.
For achieving the above object, this utility model is by the following technical solutions:
A kind of double hydraulic cylinder hoists rig, it includes derrick and base, described derrick is provided with derrick hanger, the upper strata of described base is provided with base hanger, the first derrick supporting seat and the second derrick supporting seat, lower floor at base is provided with lift oil tank, described lift oil tank is connected with the lower floor of base by rotating shaft, is provided with support bar between the upper and lower of base, and the two ends of described support bar are respectively and hinged between the upper and lower of base.
Described support bar is at least two support bars arranged in parallel.
It is provided with expansion link between the upper and lower of described base.
Compared with prior art, the beneficial effects of the utility model are: 1. simplify the structure that hoists, and alleviate weight of equipment, easier for installation; 2. save human resources, reduce production cost; 3. simple to operate, improve work efficiency.
Work process of the present utility model is:
Derrick uphill process: lift oil tank is connected with derrick hanger when derrick is in level, when lift oil tank is started to stretch out by Hydraulic Station effect, derrick is slowly boosted, drive derrick half-twist to make derrick be erectility, then derrick is connected with between the first derrick supporting seat and the second derrick supporting seat respectively; Base uphill process: being regained by lift oil tank, be connected with base hanger by lift oil tank, when lift oil tank is started to stretch out by Hydraulic Station effect, base is slowly boosted by support bar and expansion link, drives the rotation of base, makes base complete to rise.
Accompanying drawing explanation
Fig. 1 is that tradition hoists the structural representation of rig.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the structural representation after this utility model derrick rises.
Accompanying drawing labelling: the freely-supported pulley connected on otic placode, 3-man-like shelf, 4-big lifting rope, 5-derrick on 1-winch, 2-base, the boom sheave on 6-derrick, 7-traveling system, the big rope of 8-derrick drilling well, 9-derrick, 10-base, 11-derrick hanger, 12-base hanger, 13-the first derrick supporting seat, 14-the second derrick supporting seat, 15-lift oil tank, 16-support bar, 17-expansion link.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, this utility model hoisting system is further elaborated, but protection domain of the present utility model can not be limited with this.
As shown in Figures 2 and 3, the present embodiment double hydraulic cylinder hoists rig, it includes derrick 9 and base 10, described derrick 9 is provided with derrick hanger 11, the upper strata of described base 10 is provided with base hanger the 12, first derrick supporting seat 13 and the second derrick supporting seat 14, lower floor at base 10 is provided with lift oil tank 15, described lift oil tank 15 is connected with the lower floor of base 10 by rotating shaft, being provided with support bar 16 between the upper and lower of base 10, the two ends of described support bar 16 are respectively and hinged between the upper and lower of base 10.
As preferably, support bar 8 described in the present embodiment is at least two support bars arranged in parallel, in order to provides support force in the process that base rises, strengthens the stability of whole system.
As it is preferred that, the present embodiment is provided with expansion link 17 between the upper and lower of described base 10, strengthens balance and the stability of whole system.
