Abstract
A well bushing salvage device is primarily used to resolve the problem that the current salvage devices have bad effectiveness and easiness for the bushing to pull-out. The utility model characterized in that the middle of the cylinder body (1) is provided with two connection shafts (2) with thread on the two ends. The several longitudinal rectangle mouths (3) are evenly opened on the upper and the lower parts of the body (1) and the inner of the mouth (3) is jointed with the geared fastened block through the pin that fixed on the body (1). The fender board (5) is fixed between the fastened block (4) and the connection shaft (2). The well bushing fishing device has a good efficiency for the fishing bushing and is highly efficient.
Description
Technical field:
The utility model relates to the used fishing tool of well, especially well tubing socket.
Background technology:
The water that people drink divides surface water and underground water, underground water be by well from underground taking-up, sleeve pipe is arranged in the well, water pump is arranged in the sleeve pipe, by water pump water is extracted out.Sleeve pipe is for a long time abominable underground of environment, very easily corrosion, must regularly keep in repair like this sleeve pipe, and when the maintenance sleeve pipe, will be from underground taking-up sleeve pipe, taking single hooking structure to collude at present gets, this structure is salvaged the sleeve pipe weak effect, efficient is low, is difficult for sleeve pipe is taken out, and also easily sleeve pipe is colluded open-minded, from then on roll up workload and expense again, influence enterprise's cost of production and have potential safety hazard.
The utility model content:
Salvage the sleeve pipe weak effect, easily sleeve pipe colluded open-minded deficiency in order to overcome existing fishing tool, the utility model provides a kind of well tubing socket, and this well tubing socket has the characteristics that sleeve pipe is effective, efficient is high of salvaging.
The technical solution adopted in the utility model is: this well tubing socket comprises main body and connecting rod, be fixed with the connecting rod of TBE (threaded both ends) in the tubing string shape main body between two parties, the main body top and the bottom radially evenly have some axial oblong openings, be hinged with the fixture block of being with tooth by the pin that is fixed on the main body in the opening, be fixed with baffle plate on the main body between fixture block and the connecting rod.
Above-mentioned opening is 6.
The beneficial effect that the utlity model has is: because the well tubing socket is fixed with the connecting rod of TBE (threaded both ends) in tubing string shape main body, the main body top and the bottom radially evenly have some axial oblong openings, are hinged with the fixture block of band tooth in the opening by pin.When fisher under well, because of between fixture block and the opening free gap being arranged, fixture block can indentation in main body, and fisher can be lowered in the sleeve pipe smoothly, when on when carrying fixture block rely on self gravitation and angle of slope outwards to stretch, because of multi-point and wide-ranging,, sleeve pipe can be pulled out so firmly block sleeve pipe, so promptly do not damage sleeve pipe, it is good again to salvage effect, saves time, laborsaving the efficient height.
Description of drawings:
Accompanying drawing 1 is the utility model structure sectional view.
1-main body among the figure, 2-connecting rod, 3-opening, 4-fixture block, 5-baffle plate.
The specific embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
By shown in Figure 1, this well tubing socket comprises main body 1 and connecting rod 2, is fixed with connecting rod 2 between two parties in the tubing string shape main body 1, and 2 liang of epitaxial ends of connecting rod are threaded, by the connecting rod 2 upper ends salvaging master connecting-rod that is threaded, by connecting rod 2 lower ends another fisher that is threaded; Main body 1 top and the bottom radially evenly interlock and have 6 axial oblong openings 3, be hinged with the fixture block 4 of being with tooth by the pin that is fixed on the main body 1 in the opening 3, when fisher under well, because of between fixture block and the opening free gap being arranged, fixture block can indentation in main body, fisher can be lowered in the sleeve pipe smoothly, when on when carrying fixture block rely on self gravitation and angle of slope outwards to stretch, because of multi-point and wide-ranging, so firmly block sleeve pipe, sleeve pipe can be pulled out, so promptly not damage sleeve pipe, the salvaging effect is good again, save time, laborsaving, the efficient height is fixed with baffle plate 5 on the main body 1 between fixture block 4 and the connecting rod 2, the indentation amount of control fixture block 4.
During actual the use, with the connecting rod 2 upper ends salvaging drilling rod that is threaded, connecting rod 2 lower ends separate screen casing by drilling rod and connect another fisher, and two fishers are together under the lower going-into-well, on carry just and sleeve pipe can be salvaged.
Claims (2)
1, a kind of well tubing socket, comprise main body (1) and connecting rod (2), it is characterized in that: the connecting rod (2) that is fixed with TBE (threaded both ends) in the tubing string shape main body (1) between two parties, main body (1) top and the bottom radially evenly have some axial oblong openings (3), be hinged with the fixture block (4) of being with tooth by the pin that is fixed on the main body (1) in the opening (3), be fixed with baffle plate (5) on the main body (1) between fixture block (4) and the connecting rod (2).
2, well tubing socket according to claim 1 is characterized in that: opening (3) is 6.
