Description

Bucket patch device is pressed in pipeline band temperate zone

The utility model relates to a kind of pipeline band temperate zone pressure bucket patch device that leakage is handled in the pipeline internal medium circulation that do not stop.

At present, the way of lay-by temperature, pressure sealing is not to adopt the special mould clamp leak stopping, is exactly the what is called son of checking card.Its structure is by the impregnation pad of being close to the pipe leakage hole, again steel plate, fixing frame and screw are formed outward.Such problem is arranged on the technology in use, during the every place of leak stopping Leak hole, all need to process a cover jig, jig can not be pulled down from leakage pipe behind the leak-stopping, after producing parking in the future, just can pull down jig and thoroughly carry out the repair welding leak stopping, and the pipeline of leak stopping different shape is relatively more difficult, such as elbow, threeway, jar and pipe joint place etc.Even the Leak hole that has is because the leak position is special and can't handle, and in operating process because with the fixing outer steel plate again of hand to Leak hole, so not too safe.Main feature is after leak stopping finishes, not weld." adjustable screw rod roof pressure is answered the steel plate leak-stopping outward " of the research of research institute of Lan Hua company of China Petroleum Chemicals Corporation is exactly that above special use ends the tool leak stopping.

The purpose of this utility model provides a kind of pipeline under band temperature band pressure leakage state, and the leakage pipe of energy mending-leakage different shape can once be finished mending-leakage, and not needing interim machining fixture, it is simple in structure, and is safe and reliable, time saving and energy saving, use bucket patch device easy to carry.

The purpose of this utility model is achieved in that this bucket patch device mainly is made up of four parts such as compactor, mould, mending-leakage plate, wire rope.The mending-leakage plate is made up of mending-leakage cover and elastic caoutchouc, elastic caoutchouc sticks with glue agent and sticks in the mending-leakage cover and protrude the mending-leakage cover, mould is connected with bolt with the mending-leakage plate, the other end of mould is installed on the compactor, fix with jackscrew, the mending-leakage plate is pressed on the Leak hole, and wire rope encloses leakage pipe one circle and hangs on the compactor, and compactor comprises: mechanical compaction device, hand-hydraulic device and electric hydaulic device.

The utility model is because used compactor, mould, mending-leakage plate, wire rope etc., so, simple in structure, time saving and energy saving, use easy to carryly, can once finish mending-leakage, do not need interim machining fixture, particularly used the mending-leakage plate, so the pipeline of energy mending-leakage different shape is connected with bolt with the mending-leakage plate owing to mould in addition, in the operating process hand not direct control mending-leakage plate to Leak hole, so handling safety is reliable.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is that the utility model compactor adopts the pipeline band temperate zone of hand-hydraulic device to press the plan view of bucket patch device, and wherein the part is broken away;

Fig. 2 is that the utility model compactor adopts the pipeline band temperate zone of mechanical compaction device to press second embodiment's of bucket patch device plan view, and wherein the part is broken away;

Fig. 3 is that the utility model compactor adopts band temperate zone, electric hydaulic organ pipe road to press the 3rd embodiment's of bucket patch device plan view, and wherein the part is broken away;

Fig. 4 is that the utility model compactor adopts the pipeline band temperate zone of the electric hydaulic device that has tightener to press the 4th embodiment's of bucket patch device plan view, and wherein the part is broken away;

Fig. 5 is the structural front view of mending-leakage plate in the utility model, adopts and partly cuts open;

Fig. 6 is the plan view of mending-leakage plate shown in Figure 5;

Fig. 7 is the left view of mending-leakage plate shown in Figure 5;

Fig. 8 is the plan view of mould in the utility model;

Fig. 9 is the plan view of mould shown in Figure 8;

Figure 10 is the left view of mould shown in Figure 8.

Referring to Fig. 1-Fig. 4, therefrom as can be seen, pipeline band temperate zone presses bucket patch device mainly to be made up of four parts such as compactor 7, mould 4, mending-leakage plate 6, wire rope 8.Hydraulic pressure device and mechanical compaction device are a kind of extremely common Hydraulic power tools and machining, and its structure and principle and processing method no longer illustrate at this.Mending-leakage plate 6 is made up of mending-leakage cover 1 and elastic caoutchouc 2, and elastic caoutchouc 2 sticks with glue agent 3 and sticks in the mending-leakage cover 1 and protrude mending-leakage cover 1 (referring to Fig. 5).Referring to Fig. 1, mould 4 is connected with mending-leakage plate 6 usefulness bolts 9; The other end of mould 4 is installed on the hydraulic pressure device 7, fixing with jackscrew 5, mending-leakage plate 6 is pressed on the Leak hole 11, wire rope 8 encloses leakage pipe 10 1 circles and hangs on the hydraulic pressure device 7, and 2 compressions of pressure effect elastic caoutchouc are also tight with Leak hole 11 sealings, till medium does not leak, four limits of the cover of mending-leakage simultaneously 1 just in time are attached on the leakage pipe 10, material according to leakage pipe 10 is selected welding rod, welds both contacting points, and final mending-leakage plate 6 has been stayed on the leakage pipe 10.

Referring to embodiment illustrated in fig. 2, compactor 7 is to adopt the mechanical compaction device, and it is to be cooperated by nut and screw rod, and screw thread can adopt trapezoidal thread, other structure, and Placement and position relation etc. are identical with Fig. 1 embodiment.

Referring to embodiment illustrated in fig. 3, compactor 7 is to adopt the electric hydaulic device, and other structure, connection and position relation etc. are identical with Fig. 1 embodiment.

Referring to embodiment illustrated in fig. 4, compactor 7 is the electric hydaulic devices that adopt the band tightener, this embodiment adopts reverse side mending-leakage mode to carry out mending-leakage, reverse side mending-leakage mode is meant that bucket patch device is when carrying out mending-leakage, compactor 7 and mould 4 are in a side of leakage pipe 10, and mending-leakage plate 6 is at the opposite side of leakage pipe 10.Mending-leakage plate 6 and wire rope 8 usefulness bolts 9 and clamp ring 12 are fixing, and present embodiment is when using operation, the using method difference, and other structure, Placement and position relation etc. are identical with Fig. 1 embodiment.

Compactor of the present utility model comprises mechanical compaction device, hand-hydraulic device and electric hydaulic device, and all can use tightener.
