Description
Technical field
The utility model belongs to gas pipeline maintenance apparatus, relates in particular to a kind of gas pipeline repairing hydraulic packer.
Background technique
At present, the repairing of domestic town gas pipe, normally adopting and first close pipeline upstream and downstream valve, residual rock gas in pipeline is rushed to repair to operation again after diffusing completely, there is following shortcoming in this operating type: one, the engineering time long, cause part area to stop the supple of gas or steam for a long time simultaneously; Two, pipe natural gas diffuses and causes the wasting of resources; Three, the region of stopping the supple of gas or steam is larger, and the user between the valve of upstream and downstream need all stop the supple of gas or steam.And current existing pipeline plug mostly is screw rod plugging device, the screw axis power producing through manpower rotary screw realizes the shutoff of gas pipeline, the volume of this plugging device is comparatively heavy, the about 60kg of weight, need two people to move, use extremely inconveniently, and shutoff process time is long, also takes manpower simultaneously.
Model utility content
The purpose of this utility model is to provide a kind of can minimizing to close upstream valve, pipeline gas and the job step such as diffuse, and promotes and rushes to repair efficiency, and the minimizing wasting of resources, dwindles the region of stopping the supple of gas or steam, simple and light, shutoff gas pipeline repairing fast hydraulic packer.
This gas pipeline repairing hydraulic packer that the utility model provides, comprise base, jack, some connecting rods, some fixed sleevings, die holder, punch holder and location card, in the bottom of described die holder, have a jack locating slot, in a side of described punch holder, one location axis is installed, described jack is arranged on base, die holder is arranged on the top of jack, insert in the jack locating slot of die holder at the top of this jack, described fixed sleeving is arranged in the bottom surrounding of described die holder uniformly, described punch holder is arranged on die holder top, described location card is rotatable to be arranged on the axis of location, on this location card, be provided with the double wedge of some different-diameters, the bottom of this double wedge is connected with the top of die holder, the bottom of described connecting rod is arranged on base, its top is through fixed sleeving, die holder and punch holder are fixed by a nut.
For guaranteeing that gas pipeline can not wear and tear in shutoff process, the upper surface of described die holder and the lower surface of punch holder all adopt two semi-circular projection structures.
For guaranteeing the utility model die holder stress balance, described jack locating slot is opened the bottom centre at die holder.
For when the non-horizontal operation, prevent jack landing, between described base and jack, be also provided with the improved mat of a rubber.
The utility model is by being placed in gas pipeline between upper and lower clamping plate, make jack from die holder bottom jack-up die holder upwards, make the bottom connection of corresponding double wedge on itself and location card, thereby realize the clamping work to gas pipeline; More manually compare, by the hydraulic coupling shutoff of jack, can complete fast the complete shutoff of gas pipeline, and saved manpower, only need be by the shutoff of repairing position upstream during repairing, between block-up position and upstream valve, user still can just commonly use gas, reduce natural gas diffusion, reduce the region of stopping the supple of gas or steam; And the design of location card also can prevent that upper and lower clamping plate from carrying out excessive compression shutoff to gas pipeline, make its damage.The utility model is simple in structure, lightweight, nearly weighs 10 kilograms of left and right, and convenient carrying can be reduced during use and be closed upstream valve, pipeline gas and the step such as diffuse, and promotes repairing efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of Fig. 1 left view.
Fig. 3 is the structural representation of Fig. 1 right elevation.
Embodiment
From Fig. 1 to Fig. 3, can find out, this gas pipeline repairing of the utility model hydraulic packer, comprise base 1, jack 2, some connecting rods 3, some fixed sleevings 4, die holder 5, punch holder 6 and location card 7, wherein in the bottom of die holder 5, have a jack locating slot 51, in a side of punch holder 6, a location axis 61 is installed, on location card 7, be provided with the double wedge 71 of some different-diameters, jack 2 is arranged on base 1, die holder 5 is arranged on the top of jack 2, insert in the jack locating slot 51 of die holder 5 at the top of this jack 2, fixed sleeving 4 is arranged in the bottom surrounding of die holder 5 uniformly, punch holder 6 is arranged on die holder 5 tops, location card 7 is arranged on the axis 61 of location and can rotates around its axle center, the bottom of double wedge 71 is connected with the top of die holder 5, the bottom of connecting rod 3 is arranged on base 1, its top is through fixed sleeving 4, die holder 5 and punch holder 6 are fixing by a nut 31.
As can be seen from Figure 2, in the utility model, the lower surface of the upper surface of die holder 5 and punch holder 6 all adopts two semi-circular projection structures.
