Description

Wood plug gun

Technical Field

The utility model relates to the technical field of plugging, in particular to a wood plug gun.

Background

The wood plug gun is an emergency plugging auxiliary tool for the leakage and remote treatment of a metal pressure container. In daily leakage emergency rescue, a wood plug plugging method is often used for emergency leakage rescue, but under the conditions that a plugging person cannot approach due to narrow space, obstacles block the leakage point, the leakage point distance is far, the leakage quantity is large, and the leakage matter has toxicity or corrosiveness, the person cannot directly hold the wood plug for operation, for example, in a plurality of groups of pipelines assumed in high altitude, when the pipelines in the middle are leaked, due to the narrow space among the pipelines, when the wood plug is utilized for plugging, the wood plug cannot be knocked by a hammer, so that the wood plug enters the leakage point. At this time, it is inconvenient to perform plugging by using a wooden plug. Therefore, a tool capable of realizing remote nailing and plugging is needed to achieve the purpose of emergency leakage prevention.

The patent document with the application number of CN201320469580.X and the name of an oil stealing point plugging device for an oil pipeline discloses a plugging device capable of solving the plugging problem after the oil stealing point of a crude oil output pipeline is plugged. The plugging effect and the success rate of the oil stealing point after leakage can be safely and effectively improved. The oil delivery pipeline comprises a conical plug, wherein the conical plug is inserted with a lead screw of a bracket, and the bracket is fixed on the oil delivery pipeline through a fixing belt. Under the support of the support, the conical plug is pressed into an oil stealing point of oil pipeline leakage through the screw rod. The device needs to be provided with a large operation space setting bracket. The method is not suitable for temporarily plugging the leakage points by using the wooden plugs in a narrow space.

The patent document with the application number of CN200720159335.3 entitled quick plugging device for oil pipeline discloses a quick plugging device for improving the convenience of plugging a stolen hole. The upper part of the cylinder body is fixed with a sealer, the outer surface of the lower part of the cylinder body is provided with threads, an inner hollow pipe is arranged in the cylinder body and is installed with the sealer through the threads on the outer surface of the cylinder body, the uppermost end of the inner hollow pipe is fixed with another sealer, the lower end of the hollow pipe is fixed with a conical wood plug, a throwing rod penetrates through the other sealer and the inner hollow pipe, the lower end of the throwing rod is positioned above the conical wood plug, and a vent valve is arranged on a pipe communicated with one side of the cylinder body. When the plugging operation is carried out, all the components are assembled, the inner hollow pipe is rotated, and the conical wood plug is retracted into the cylinder. The cylinder is arranged on a valve (the valve is provided with internal threads) at a theft hole of an oil pipeline by an external thread at the lower part of the cylinder, and the gate is opened. And then the hollow pipe is rotated to drive the conical wooden plug into the valve. And opening the vent valve, further rotating the hollow pipe, and judging whether the conical wood plug enters the theft hole by observing the change of the pressure of the crude oil flowing out of the vent valve. After the conical wood plug enters the theft hole, the rotation of the inner hollow pipe is stopped, the conical wood plug is impacted downwards by a throwing rod, so that the conical wood plug is separated from the inner hollow pipe, and the conical wood plug is impacted continuously until the hollow pipe is not leaked. And cleaning the adhesive on the periphery of the adhesive iron plate by using a fire welding gun, welding a steel plate, and screwing the hollow pipe back. And (3) observing the oil outlet condition of the emptying valve, when oil is not discharged at all, detaching the valve at the theft hole, sleeving a steel pipe slightly larger than the conical wooden plug on the outer surface of the valve, welding the steel pipe on a steel plate, sealing the steel pipe, and thus completing the plugging operation. The device needs to possess the space that can place pipe and relief valve when carrying out the leaking stoppage operation, though can support the wooden plug through the hollow tube, but the length of hollow tube can not change, and the suitability is not high.
