For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of chain pipe plugging fixture, comprise for blocking pipe leak source rubber plate, for compress the steel plate of rubber plate, hold-down mechanism and along rubber plate length direction uniform at least two for by hold-down mechanism and the fixing ring chain of pipeline to be repaired.
Described hold-down mechanism comprise arc plate and arcuately plate length direction uniform at least two cover nuts, the axis being parallel of described arc plate axis and described pipeline to be repaired, described nut to be fixedly installed on arc plate outer side wall and to install hold-down bolt with nut screw connection.
Described ring chain to be hung on arc plate and to form enclosed construction by means of chain tensioner in the middle part of described ring chain.
Described chain tensioner comprises the hinged rectangular frame of the hinged screw rod of tail end and chain one end and tail end and the other one end of chain, described rectangular frame end face is provided with through hole, screw rod is arranged through described through hole, and screw rod is provided with the locking nut with its screw-thread fit through one end of through hole.
The beneficial effect adopting technique scheme to produce is: by arranging ring chain and hold-down mechanism with rubber plate is supporting, when rotating forward hold-down bolt, hold-down bolt lower end contacts with upper surface of steel plate, the nut be rotated through on arc plate of hold-down bolt is converted into the radial motion of arc plate, because the ring chain length forming closed ring structure is constant, therefore, the radial motion of arc plate is subject to the restriction of ring chain, the hold-down bolt rotated progressively can only compress steel plate, cause rubber plate plastic deformation, rubber plate contacts with pipeline external surface to be repaired, reach the object of seal leakage point, be applicable to the leak stopping of unlike material and different occasion pipeline, not only be applicable to low pressure pipeline, also be applicable to the interim leak stopping of high pressure pipe line, improve Security and overhaul efficiency, guarantee normal production.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Pipeline is with pipe, pipe fitting and valve etc. be connected into for carrying gas, the system of the fluid of liquid or band solid particle, usually, fluid is through blower, compressor, after the supercharging of the device such as pump or boiler, low pressure place is flowed to from the high pressure of pipeline, also pressure or the gravity transfer of fluid self can be utilized, having many uses of pipeline is general, mainly be used in feedwater, draining, heat supply, give gas, long distance delivery oil and natural gas, agricultural irrigation, in hydraulic engineering and various commercial plant, pipeline can simply be divided into high pressure pipe line and low pressure pipeline according to the height of conveying hydrodynamic pressure, because pipe-line system uses pipe and pipe fitting combination to install, pipe and pipe fitting are because of manufacturing deficiency or life-span restriction, in use may because of collision or manufacturing deficiency, easy generation leak source, run or pipe-line system less to Influence of production after stopping for can intermittently stopping, after appearance is revealed, pipeline operation can be stopped to carry out pipe or pipe fitting replacing and leak stopping at once, but for the pipe-line system of some crucial production sites, if rashly stop operation, heavy economic losses will be caused, therefore, in pipe-line system area of maintenance, pipe-line system interim leak stopping with pressure is a key job, current domestic conventional pressurized leaking stoppage method mostly is seam leakage blinding method, plug leak stopping method, sealing case leak stopping etc., seam leakage blinding method is for be down to minimum rear repair welding by pipeline pressure, plug leak stopping method is at pipe leakage point place welded nut, bolt is twisted after being wound around sealer, sealing strip and stop dielectric leakage on nut, sealing case leak stopping is make sealing case according to leakage point size shape, and sealing case welds after using metal-to-metal adhesive sealing by leak source.Above method exists that poor safety performance, operating efficiency are low, impact is normally produced, operating personnel requires high, and is only applicable to the very low pipeline of pressure, cannot timely process with pressure for the higher pipe leakage fault of pressure; For this reason, the utility model provides a kind of chain pipe plugging fixture as shown in Figure 1-2, comprise for blocking pipe leak source 9 rubber plate 4, for compress the steel plate 3 of rubber plate 4, hold-down mechanism and along rubber plate 4 length direction uniform at least two for by hold-down mechanism and the fixing ring chain 6 of pipeline to be repaired; Described hold-down mechanism comprise arc plate 5 and arcuately plate 5 length direction uniform at least two cover nuts 2, the axis being parallel of described arc plate 5 axis and described pipeline to be repaired, described nut 2 is fixedly installed on to coordinate on arc plate 5 outer side wall and with nut 2 installs hold-down bolt 1; Described ring chain 6 to be hung on arc plate 5 and to form enclosed construction by means of chain tensioner 7 in the middle part of described ring chain 6; Described chain tensioner 7(is see accompanying drawing 3) comprise the hinged rectangular frame of the hinged screw rod of tail end and chain one end and tail end and the other one end of chain, described rectangular frame end face is provided with through hole, screw rod is arranged through described through hole, and screw rod is provided with the locking nut with its screw-thread fit through one end of through hole.
In embody rule process, when pipeline a part to be repaired occurs revealing fault, first rubber plate and the steel plate of certain length and width is selected according to the situation of Pipeline Leakage Point, select the length of ring chain according to the diameter of pipeline to be repaired simultaneously, then two covers or the above ring chain of two covers are walked around pipeline to be repaired, and chain two ends chain tensioner is connected into the ring chain be centered around in pipe circumference to be repaired, then rubber plate and steel plate are covered Pipeline Leakage Point place, arc plate is located in ring chain simultaneously, and be positioned at directly over steel plate, finally tighten hold-down bolt to compress steel plate, nut quantity on arc plate can be selected according to the length of steel plate, it can be two, also can be two or more, nut can directly be welded on arc plate, also tapped hole can be set on arc plate, hold-down bolt directly coordinates with tapped hole, hold-down bolt compresses steel plate to Pipeline Leakage Point to be stopped revealing.
The utility model is by arranging ring chain and hold-down mechanism with rubber plate is supporting, when rotating forward hold-down bolt, hold-down bolt lower end contacts with upper surface of steel plate, the nut be rotated through on arc plate of hold-down bolt is converted into the radial motion of arc plate, because the ring chain length forming closed ring structure is constant, therefore, the radial motion of arc plate is subject to the restriction of ring chain, the hold-down bolt rotated progressively can only compress steel plate, cause rubber plate plastic deformation, rubber plate contacts with outer surface of steel tube to be repaired, reach the object of seal leakage point, not only be applicable to low pressure pipeline, also be applicable to the interim leak stopping of high pressure pipe line, improve Security and overhaul efficiency, guarantee normal production.
