Abstract

The utility model discloses a hydraulic pipe-clamping leak stopper, comprising a hydraulic oil pump (1), a hydraulic cylinder (2), a piston (3), a piston head (4), an upper clamp (5), a lower clamp (7) and a hydraulic-pliers moving hoop (8), wherein the hydraulic oil pump is connected at an inlet end of the hydraulic cylinder; the upper clamp is fixedly connected on the piston head of the piston in the hydraulic cylinder; the lower clamp is fixed in the hydraulic-pliers moving hoop which is arranged below the hydraulic cylinder; and one side edge of the hydraulic-pliers moving hoop and the hydraulic cylinder are in a hinged structure, and the other side edge of the hydraulic-pliers moving hoop is of a movable connecting structure. According to the hydraulic pipe-clamping leak stopper, the leak stopping can be carried out on a leaking pipeline under the operating state of equipment, so that the normal conduction of production can be further ensured. The hydraulic pipe-clamping leak stopper has the characteristics of simple and reasonable structure, safe and reliable operation and convenience in operation.

Description

A kind of hydraulic pressure clamp leak stopping apparatus
Technical field
The utility model relates to a kind of small pipeline pressure sealing device technique field, relates to a kind of hydraulic pressure clamp leak stopping apparatus specifically.
Background technique
Known 210MW cogeneration units, all kinds of hydrophobic and row's atmosphere duct is numerous, because of multiple reason, cause hydrophobic and row's atmosphere valves leakage phenomenon commonplace.In normal productive process, because of pipeline belongs to HTHP, can't change valve more, and under the band pressure condition, also can't weld stifled pipeline.Long-term run, drip, leak cause great amount of heat energy and demineralized water loss, make manufacturing efficiency receive very big influence, have increased cost of production simultaneously, and can form potential safety hazard.For solving this type of problem, the professional anchor clamps of many at present employings are squeezed into blocking agent and are carried out shutoff, but expense is higher, and leak stopping company is far away apart from my company's distance, and the discovery leak source can not in time be handled.
Summary of the invention
A kind of hydraulic pressure clamp leak stopping apparatus that the purpose of the utility model provides to existing deficiency in the above-mentioned existing technology just.This device can carry out leak stopping to leakage pipe under equipment running status, ensured normally carrying out of producing, have simple in structure, safe and reliable to operation,, convenience operation.
The purpose of the utility model can realize through following measure: a kind of hydraulic pressure clamp leak stopping apparatus; Comprise hydraulic-pressure pump, oil hydraulic cylinder, piston, piston head, go up the movable clip of anchor clamps, lower clamp and hydraulic tongs; Said hydraulic-pressure pump is connected the entrance point of oil hydraulic cylinder; Last clamps is connected on the piston head of piston in hydraulic cylinder, and lower clamp is fixed in the movable clip of hydraulic tongs, the movable clip of said hydraulic tongs be arranged on oil hydraulic cylinder below; One of which side and oil hydraulic cylinder are the structure that is articulated and connected, and another side is a movable connection structure.
Described upward anchor clamps of the utility model and lower clamp are the trapezoid body structure.
The movable clip of the described hydraulic tongs of the utility model is the tetragonal body structure, and its side that is articulated and connected is articulated and connected, flexibly connects side by movable position limit pin socket connection by fixator pins.
The utility model can carry out leak stopping to leakage pipe under equipment running status, ensured normally carrying out of producing.Effectively reduce maintenance cost.Have simple and reasonable, safe and reliable to operation, convenience operation.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model work schematic representation.
Among the figure: 1, hydraulic-pressure pump, 2, oil hydraulic cylinder, 3, piston, 4, piston head, 5, go up anchor clamps, 6, movable position limit pin, 7, lower clamp, 8, the movable clip of hydraulic tongs, 9, fixator pins.
Embodiment
To combine to implement illustration (accompanying drawing) below the utility model further describes.
Combine shown in Figure 2ly like Fig. 1, the described hydraulic pressure clamp of present embodiment leak stopping apparatus comprises hydraulic-pressure pump 1, oil hydraulic cylinder 2, piston 3, piston head 4, goes up anchor clamps 5, movable position limit pin 6, lower clamp 7, the movable clip 8 of hydraulic tongs and fixator pins 9 are formed.Said hydraulic-pressure pump 1 is a manually operated type, and its import is communicated with hydraulic oil container, outlet is communicated with oil hydraulic cylinder 2, and the hydraulic pressure outlet of oil hydraulic cylinder 2 is communicated with hydraulic oil container.Last anchor clamps 5 process by the thick steel plate of 20mm with lower clamp 7, are the trapezoid body structure, and last anchor clamps 5 are fixedly connected on the piston head 4 of piston 3, and said piston 3 is the pot type piston of diameter 30mm.Lower clamp 7 is fixed on the movable clip 8 of hydraulic tongs.The movable clip 8 of said hydraulic tongs be arranged on oil hydraulic cylinder 2 below; Processed by the thick general steel plate of 40mm, be tetragonal body, a side wherein is articulated and connected by fixator pins 9; Opposite side is by movable position limit pin 6 socket connections, and lower clamp 7 is fixed in the movable clip 8 of hydraulic tongs.Fixator pins 9 is processed by the round steel of 12mm.Movable position limit pin 6 is that the round steel by 16mm processes.
When the utility model uses, at first pull out movable position limit pin 6, open the movable clip 8 of hydraulic tongs; Place anchor clamps 5 middle with lower clamp 7 leakage pipe, the movable clip 8 of the hydraulic tongs that closes is plugged movable position limit pin 6; Primer fluid oil-pressing pump 1, the hydraulic oil that is come by hydraulic fluid tank enters into oil hydraulic cylinder 2 through hydraulic-pressure pump 1, promotes piston 3 and moves downward; Thereby driving piston head 4 moves downward; At this moment the last anchor clamps 5 that are fixed on the piston head 4 will compress leakage pipe jointly at the downward effect of piston head 4 and the lower clamp 7 that is fixed in the movable clip 8 of hydraulic tongs, and extrusion pipe is to limit position, make tube wall generation plastic deformation after; Unclamp the movable clip 8 of hydraulic tongs, accomplish leak stopping.
