Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As shown in Figure 1, the utility model embodiment provides a kind of fishing spear device, and fishing spear device comprises: mobile jib 10, grasping mechanism 20, driving mechanism 30 and bindiny mechanism 40.Wherein, grasping mechanism 20 is arranged on swingably on mobile jib 10, and driving mechanism 30 is also arranged on mobile jib 10, the first end of bindiny mechanism 40 and the output of driving mechanism 30 hinged, the second end and the grasping mechanism 20 of bindiny mechanism 40 are hinged.Driving mechanism 30 operationally can make output stretch out or shrink, and moves to make bindiny mechanism 40 drive grasping mechanism 20 to swing on mobile jib 10 by output, and then can adjust the angle that grasping mechanism 20 opens.The size of its open angle and tubing string is suitable, so can adapt to the tubing string of different tube diameters.Wherein, the optional electric control hydraulic device of driving mechanism 30 drives, and driving mechanism 30 is provided with cable 50, is controlled by cable 50 pairs of driving mechanisms 30.
Application the technical solution of the utility model, mobile jib 10 arranges grasping mechanism 20 swingably, bindiny mechanism 40 connects driving mechanism 30 and grasping mechanism 20 respectively, driving mechanism 30 moves by driving bindiny mechanism 40, swing to drive grasping mechanism 20, so can when fishing string, make grasping mechanism 20 capture tubing string by operation driving mechanism 30, with by tubing string from casing program design out.Different tubing string can be salvaged by this device, without the need to more exchange device, while being convenient to salvage, reduce salvaging cost.Further, this device is simple to operate, is convenient to user and operates fishing string.
Wherein, in the present embodiment, adopt the first fork 21 to swing on mobile jib 10, this structure is simple, is convenient to install and operation.
Alternatively, this bindiny mechanism 40 comprises connecting rod 41, and one end and the output of connecting rod 41 are hinged, and the other end and the grasping mechanism 20 of connecting rod 41 are hinged.Also can be the combining structure of connecting rod 41 and sleeve 42, wherein, sleeve 42 be set on mobile jib 10, and the output of driving mechanism 30 is connected with sleeve 42, and one end and the sleeve 42 of connecting rod 41 are hinged, and the other end and the grasping mechanism 20 of connecting rod 41 are hinged.Sleeve 42 moves on mobile jib 10, and then drives connecting rod 41 to move, and connecting rod can regulate the pendulum angle of the first fork 21 in moving process.By the structure that connecting rod 41 and sleeve 42 combine, device can be made more firm, and so can exerting all one's strength, it is more stable to transmit.
Particularly, in order to increase the stability of device entirety.This grasping mechanism 20 comprises two the first forks 21, and bindiny mechanism 40 comprises two connecting rods, 41, two the first forks 21 and is connected correspondingly with two connecting rods 41.One of them the first fork 21 and a connecting rod 41 combine, and another first fork 21 combines with another connecting rod 41.Further, alternatively, with mobile jib 10 for symmetrical centre is symmetricly set on mobile jib 10 both sides.
In order to simplification device structure, particularly, the pin joint of one of them the first fork 21 on mobile jib 10 is identical with the pin joint of another the first fork 21 on mobile jib 10.In the present embodiment, on two the first forks 21, the hinged end hinged with mobile jib 10 overlaps on mobile jib 10.Wherein, this hinged end can be arranged on the inside of mobile jib 10, such as, on mobile jib 10, arrange through hole, arranges rotating shaft and rotate around the axis to make two the first forks 21 in through hole; Also can be set directly on the surface of mobile jib 10.
Alternatively, arrange identical with two the first forks 21, the hinged end hinged with sleeve 42 of two connecting rods 41 also can be on the sleeve 42 stacked.
In the present embodiment, one end that this grasping mechanism 20 also comprises crawl section 22, first fork 21 is arranged on mobile jib 10, and crawl section 22 is arranged on the other end of the first fork 21.By being arranged on crawl section 22, so that mount with tubing string.
Alternatively, this crawl section 22 can be set to mill teeth structure.
In concrete salvaging process, because disconnected de-tubing string mostly is hollow section, without the structure that namely step is connected with fishing spear device, and quality comparatively greatly, and therefore, often can grab and drag for not firm, tubing string easily drops in salvaging process.The utility model mainly have employed slider-crank mechanism, driven by driving mechanism 30, open in tubing string inside to make the first fork 21, then rotate this device, and then by the mill teeth installed on the first fork 21, the step of certain depth can be milled out in tubing string inside or mill out indenture in tubing string inside, coordinated with step or indenture by mill teeth, to make tubing string be articulated on this fishing spear device, then promote disconnected de-tubing string, can salvage be completed.Specifically, device is stretched into disconnected de-tubing string inner, start electric control hydraulic device, this device controls sleeve 42 and moves down, sleeve 42 drives connecting rod 41 to move down, connecting rod 41 makes the first fork 21 launch in disconnected de-tubing string inside, mill teeth contacts with disconnected de-pipe string internal wall, rotate this device, make mill teeth mill out a step in disconnected de-tubing string inside, or mill out indenture in tubing string inside, then on carry fishing spear device, make crawl section 22 clamp tubing string by disconnected de-tubing string deadweight, complete salvaging task.To tubing string be carried to ground, startup electric control hydraulic device moves sleeve 42 and just device can be taken out in tubing string.The fishing spear device that application the present embodiment provides, as long as in the strength range of this device, the deadweight of tubing string is larger, then capture tighter, so can prevent disconnected de-tubing string from dropping in salvaging process further.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
