Abstract
The utility model relates to a fisher for a plastic liquid supply pipe in a freezing pipe during the mine shaft freezing construction. The upper and lower ends of counterweight round steel are articulated with upper and lower lifting rings respectively; the lower lifting ring of the counterweight round steel is fixed with the upper lifting ring of a fishing steel pipe; and barbs are fixed on the inner wall of the lower end of the fishing steel pipe. The fisher provided by the utility model has a simple structure, is convenient to use and can conveniently fish the damaged plastic liquid supply pipe in the freezing pipe.
Description
Technical field
The utility model relates to when fracture takes place the plastics feed pipe in the freezing pipe in a kind of pitshaft frozen construction, the fisher that is adopted.
Background technology
In the pitshaft frozen construction process, the plastics feed pipe of underlying often has the joint connection in the freezing pipe.In case if feed pipe connects insecure coming off, whole freezing hole is scrapped in the freezing engineering work progress, the adjacent holes spacing is strengthened, cause frost wall to delay to hand over circle, pit shaft is prone to cause out " skylight " gushing water to gush the sand accident in tunneling construction.After freezing engineering finished, the plastics feed pipe needed to reclaim, may be insecure because of connecting, and the rate of recovery that reduces feed pipe increases the construction cost of freezing engineering.The plastics feed pipe plays considerable effect in freezing engineering, must guarantee that in running it is intact, in case plastic pipe comes off or ruptures, must handle immediately, otherwise engineering is caused serious harm.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of plastics feed pipe fisher, and it is simple in structure, and is easy to use, can salvage the plastics feed pipe that in freezing pipe, has damaged easily.
The utility model solves the technical scheme that its technical problem takes: the upper and lower side of counterweight round steel is hinged upper and lower drop handle respectively, and the following drop handle of counterweight round steel is fixed with the last drop handle of salvaging steel pipe, fixing hangnail on the lower end inwall of salvaging steel pipe.
Described hangnail has 2-4 on same cross section.
Described hangnail is axially having 2-4 row.
Described hangnail is a triangle.
On the salvaging steel pipe walls of said hangnail corresponding position perforate is arranged, convenient welding hangnail.
1), can be according to the interior diameter of underlying freezing pipe and the external diameter of plastics feed pipe the utlity model has advantage:, the inside and outside footpath of adjustment fisher be so that the plastics feed pipe can be pulled out smoothly.2), the fisher steel pipe and the φ 90mm round steel that adopt be used, and increased the deadweight of fisher, in the plastic pipe entering fisher steel pipe of guaranteeing to come off, improved salvaging efficient.3), fisher falls point and adopts welding, can be according to the diameter of feed pipe, and connect feed pipe goat's horn diameter adjustment fisher and fall the angle of inclination of point.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the utility model structural representation;
Fig. 2 salvages the steel pipe partial enlarged front view for the utility model;
Fig. 3 salvages the steel pipe partial enlarged left view for the utility model.
The specific embodiment
As shown in Figure 1, the upper and lower side of counterweight round steel 3 is hinged upper and lower drop handle 2,4 respectively, and the following drop handle 4 of counterweight round steel 3 is fixing with the last drop handle of salvaging steel pipe 65, fixing hangnail 7 on the lower end inwall of salvaging steel pipe 6.
Described hangnail 7 has 2-4 on same cross section.Described hangnail 7 is axially having 2-4 row.Described hangnail 7 is a triangle.On salvaging steel pipe 6 walls of said hangnail 7 corresponding positions perforate 8 is arranged, convenient welding hangnail 7.
During use; The last drop handle of counterweight round steel 32 is fixing with the wire rope 1 of puffer, will salvage steel pipe 6 then and slowly put into and need the freezing pipe salvaged, treat counterweight round steel 3 get into fully freezing pipe interior after; Transfer fast; Utilize counterweight round steel 3 and the deadweight impact force of salvaging steel pipe 6, salvaging steel pipe 6 is entangled the plastic pipe in the freezing pipe, promote then.Can plastic pipe be caught on because salvage the hangnail of steel pipe 6, just salvaged so carry the plastic pipe of falling in the process in the freezing pipe on the winch.
