When utility model is used for plugging, a tool is fixed at both sides of a leakage part through a magnet base which can open and close, the lifting rod is lifted, the pressing block is coated with adhesive or lined with a soft rubber sheet, and the localizer is pushed so that the pressing block can plug a leak source quickly under the action of a spring. After the pressing block is fixed by the adhesive, the tool can be taken off.

Description

Clamping apparatus for quick plug

The utility model relates to a kind of quick-speed jigs that carries out repairing leakage under suspended state not, be suitable for pressure＜0.6MPa, temperature in-20～200 ℃ scope, the scene of leaking media such as oils, steam, water in pipeline within the φ 2mm of aperture or the container leak stopping of not stopping work.

Under the condition of uniform temperature and pressure, to block paroxysmal leakage position, the material that requires leak stopping at first can the media-resistant corrosion and certain intensity is arranged, next is to make the pressure of external force greater than medium, will have a device to realize at the pipeline or the external container that leak usually.Therefore at the different size of leakage position, shape, will process as required, and so not only will take measurements, process, and can't realize leak stopping because of the diameter of container is excessive sometimes with a lot of times.

At present, on-the-spot blocking method commonly used is the Furmanite technology, its equipment is by the high-pressure injection rifle, high-pressure service pump and the compositions such as annular holder that match with leakage position, anchor clamps at different position processing different size shapes, working procedure is to arrive first the scene to take measurements, the worker workshop of accompanying each other of publishing picture then, at last anchor clamps are arrived leakage position with bolt, with joint filling gun is associated on the anchor clamps, under the effect of high pressure hand-operated oil pump, constantly sealing compound is injected anchor clamps, be full of whole Seal cage, make the pressure of the pressure of sealing compound generation, make to leak to stop greater than leaking medium.A process like this is for our desired Applicable scope, and with regard to some the numerous rope that shows, the time is oversize, and labor intensity is big.

The purpose of this utility model is to provide a kind of easy to use, does not need the reprocessing of part and can effectively reach a kind of device of instantaneous leaking-stopping purpose when leak stopping.

The purpose of this utility model is achieved in that the pulling force that is used on the place's of being adsorbed Vertical direction is not less than the magnet base of 1000N, anchor clamps are fixed on easily the both sides of leakage position, then by the elastic force releasing mechanism, briquetting is got lodged on the leak source, cling briquetting with Bond, take off a whole set of anchor clamps.Therefore operating process is short, and labor intensity reduces greatly, and tool is safe and reliable.

The utility model volume pressure little, in light weight, that resist dielectric leakage be with spring by lifting arm, act on and realize on the briquetting, the area of briquetting is 4(cm) * 4(cm)=16(cm ²), the elastic force of spring is 4kg, the pressure on the unit area is 0.25kg/cm ², if the dielectric leakage aperture is 2mm, interior pressure 0.6MPa, its pressure is about 0.2kg, and external pressure＞interior pressure can be realized leak stopping.

The concrete structure of model utility is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is according to a kind of anchor clamps work plan view that is used for instantaneous leaking-stopping that the utility model proposes.

Fig. 2 is that the utility model anchor clamps crossbeam (6) rotates schematic representation around the hole that stand (7) is located.

Fig. 3 is the positioning work piece schematic representation of the utility model anchor clamps.

Fig. 4 is an A-A partial cutaway schematic among Fig. 1.

Fig. 5 is the schematic representation of the utility model anchor clamps briquetting.

Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete clamp device that the utility model proposes.

These anchor clamps comprise the permanent magnetic support (2) that has switch (1), the switch (1) that turns clockwise is connected magnetic circuit, magnetic base promptly sucks with the place of being adsorbed, otherwise cutting off magnetic circuit throws off with the place of being adsorbed, stand (3) is fixed on the magnetic support, in a guide rail (4) is arranged, can supply crossbeam (5) to slide up and down within it, crossbeam (6) can be done rotation around the hole that stand (7) are located, (shown in Fig. 2 dot and dash line), positioning work piece (8) can slide on crossbeam (6) plane, spring (9) be thrust to the right forever, locating stud on the positioning work piece (10) is through in the hole of fixed plate (11), make positioning work piece can only do horizontal rectilinear motion, when shadoof (20) handle (12) being mentioned with hand, when rising to certain position (13), shadoof is blocked at the protruding place of device endoporus position (14) that is positioned, shadoof promptly can not be axially moved, can not do radial motion, thereby be fixed, the crossbeam on shadoof (5) is to be fixed in the positioning hole on the crossbeam (5) with primary screw (15), briquetting (16) is to be screwed in the shadoof bottom with nut, compact materials is a steel, can serve as a contrast media-resistant rubber or smear Bond, and R orphan's degree coincide with the place of being blocked.

The working principle of the utility model anchor clamps is as follows:

The magnet base switch opens is fixed on the both sides of leakage point, be used to mention handle, (13 place) is stuck after putting in place, locate to illustrate around axle (7) then as dot and dash line, rotation is 90 °～170 ° from the angle that mouth (18) comes out to lifting arm (20) and stand (3), raise the lipophilic adhesion-blocker at briquetting when being convenient to block up oil, can serve as a contrast the media-resistant rubber when water blockoff or other medium, reset at last in the guide hole (4), promote (17) left with the hand level and locate, shadoof is put down rapidly, briquetting is pushed down leakage point, with Bond briquetting is bonded on the tube wall again, after Bond is fixing, unscrews retaining screw (15), turn on connecting of shadoof and briquetting, can be rotated counterclockwise switch (1), cut off magnetic circuit, take off anchor clamps.Finish whole leak stopping process.

Claims (2)

1, a kind of anchor clamps that are used for instantaneous leaking-stopping, these leak stopping anchor clamps have a fixing fast magnetic support (2), there is one can supply the directed guide rail (4) that moves of crossbeam (5) in the stand thereon (3), after it is characterized in that shadoof (20) is mentioned and blocking with positioning work piece (8), crossbeam (5) can be from axle half-twist～170 ° of outlet (18) around (7) position, be convenient to gluing or lining media-resistant rubber on the briquetting that shadoof connects, can aim at leak source after resetting.

2, anchor clamps according to claim 1 is characterized in that shadoof (20) and briquetting (16) are scyewed joint, back out shadoof after the leak stopping, so that fetch anchor clamps.
