Abstract
The utility model provides a propeller strut supporting legs, including the base, it is provided with the articulated ear that is used for connecting propeller strut supporting legs to slide on the base, be provided with on articulated ear can lock the locking device of dying on the base with articulated ear, be provided with on the base and drive articulated ear on the base gliding auto-lock jack, there is manual oil pump through hose connection on the auto-lock jack, adopt this technical scheme because articulated ear slides to set up on the base, can realize articulated ear removal through auto-lock jack, thereby can remote control carries out propeller strut's angular adjustment, only need lock articulated ear after the angular adjustment can, therefore adjust convenient operation is swift.
Description
Technical Field
The utility model relates to the field of petroleum equipment, in particular to a support leg of a propeller strut.
Background
The drilling machine derrick relies on the propeller strut to support the derrick in the lifting and erecting process, the angle of the propeller strut influences the vertical angle of the derrick, the supporting position of the propeller strut in the traditional structure is fixed and not adjustable, the derrick is far away from or near the propeller strut through the expansion and contraction of jackscrews at the top of the artificial high-air-conditioning propeller strut, and therefore the adjustment of the perpendicularity of the derrick is realized, the operation is inconvenient, the adjustment is time-consuming and labor-consuming, and more because the adjustment work is high-altitude operation and faces danger.
Disclosure of Invention
In order to solve the defects in the prior art, the device is convenient to operate and can accurately adjust the supporting angle of the support leg of the propeller strut.
The technical scheme adopted by the utility model is as follows: the utility model provides a propeller strut supporting legs, includes the base on slide and be provided with the articulated ear that is used for connecting propeller strut supporting legs the articulated ear on be provided with the locking device that can lock articulated ear on the base on be provided with the self-locking jack that can drive articulated ear and slide on the base the self-locking jack have manual oil pump through hose connection.
Preferably, the base is provided with a limit screw rod which can adjust the length and is used for jacking the hinge lug relative to one end of the self-locking jack.
Preferably, the locking device is a bolt.
The utility model has the beneficial effects that: by adopting the technical scheme, the hinged lugs are arranged on the base in a sliding manner, and can move through the self-locking jack, so that the angle adjustment of the propeller strut can be remotely controlled, and the hinged lugs are only required to be locked after the angle adjustment, so that the adjustment operation is convenient and quick.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
FIG. 2 is a practical state diagram of the present utility model;
in the figure, 1 is a base, 2 is a hinged lug, 3 is a locking device, 4 is a self-locking jack, 5 is a hose, 6 is a manual oil pump, 7 is a limit screw, 11 is a derrick, 12 is a derrick drilling floor, 13 is a propeller strut and a is a propeller strut supporting leg.
Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
The technical scheme of the utility model is as follows: the bracket supporting leg shown in fig. 1 comprises a base 1, a hinge lug 2 is slidably arranged on the base 1, a self-locking jack 4 capable of driving the hinge lug 2 to move is further arranged on the base 1, the self-locking jack 4 is connected with a manual oil pump 6 through a hose 5, the hinge lug 2 is made to slide on the base 1 by pressurizing or depressurizing the manual oil pump 6 when the base 1 needs to be adjusted, so that the position of the hinge lug 2 is adjusted, after the position of the hinge lug 2 is adjusted, the position of the hinge lug 2 needs to be locked to avoid the movement of the hinge lug 2, and therefore a locking device 3 is further arranged on the hinge lug 2, and the locking device 3 in the embodiment is a bolt. In order to avoid the hinge lug 2 to move the transition, cause the derrick angle to change too big and empty, still be provided with spacing screw rod 7 on base 1, spacing screw rod 7 can adjust length for limit hinge lug 2's extreme position, after hinge lug 2 moved the assigned position, still can be through spacing screw rod 7 and auto-lock jack 4 cooperation to hinge lug 2 further consolidate the locking.
As shown in fig. 2, the base 1 is fixed on a derrick drilling floor 12, and when the angle of the propeller strut 13 needs to be changed, the locking device 3 is only required to be loosened, and the self-locking jack 4 is driven by the manual oil pump 6 to adjust the hinge lug 2. From the figure, it can be seen that the self-locking jack 4 can only push the hinge lug 2 to move to one side of the derrick 11, and when the hinge lug 2 is required to be retracted, the hinge lug 2 is driven to retract by the action force of the dead weight of the supporting leg of the self-locking propeller strut 13 in the horizontal direction after the pressure is relieved through the manual oil pump 6.
The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model are included in the protection scope of the present utility model.
