Description

Technical Field

[0002] Water pipes are mainly divided into three types according to their manufacturing materials: plastic pipes, metal pipes and composite pipes. Municipal building materials usually use metal pipes due to their high frequency of use and relatively harsh working environment. Since building water pipes are usually constructed by buried wall, in order to ensure their service life, strict quality inspection is required before landfill, and comprehensive consideration is given to factors such as materials, pressure, corrosion resistance, etc. to ensure the reliability and durability of the system.

Then, a rubber ring sealing cover is provided on the outer side of the bottom end of the pipe to be tested to prevent water seepage. After completing the above operations, the water pump provided in the water tank is started to make the water pump suck out the water in the water tank and introduce it to the liquid outlet through the liquid pipeline, and then discharge it into the pipe from the liquid outlet until the pipe is filled. The free end of the pipe is sealed. After a certain test time, check whether there is any sign of water seepage near the equipment to determine the sealing of the pipe. After completing the sealing test, the hydraulic rod is driven to shorten, and the water sealed in the pipe will flow back into the water tank from the liquid outlet opened on the outside of the control cylinder. After the water completely returns to the water tank, the liquid components in the water tank are sampled and tested to determine whether there is oil stain, preparation residue and other pollution inside the pipe.

[0038] The specific usage and function of this embodiment are as follows:

[0039] The support assembly provided in the present invention can enable the device to support and fix special-shaped pipes of different shapes. After the fixing is completed, a test ball is put in through an inlet at a higher position of the pipeline. The defect position in the pipe can be roughly determined by combining a distance measuring rope and a test ball of a corresponding size. When it is necessary to support and fix the special-shaped pipe, the longer end of the straight pipe part of the special-shaped pipe is selected, and the free end of the special-shaped pipe is kept in an upward direction, and the longer end of the straight pipe part of the special-shaped pipe is horizontally placed between the fixed clamp 33 and the movable clamp 8, and then the first telescopic rod 10 is shortened. At this time, the first telescopic rod 10 will drive the movable clamp 8 where the side plate 9 is located to move downward, so that the movable clamp 8 and the fixed clamp 33 clamp the pipe to be tested together;

[0040] After the clamping is completed, the positions of the movable frame 6 and the rotating frame 1 are adjusted according to the position of the free end of the pipe until the rotating frame 1 and the free end of the pipe are in the same plane. At this time, the position of the movable plate 23 on the rotating frame 1 is adjusted by the traction assembly, so that the movable plate 23 and the clamping sleeve 24 set on the movable plate 23 drive the sliding rod 28 connected to the second telescopic rod 22 to move until the fixed assembly moves to the outside of the free end of the pipe, and then the position of the clamp 21 in the fixed assembly needs to be manually adjusted, and the first screw 1816 and the second screw 1916 are driven to rotate by rotating the knob 25, so that the two clamps 21 are close to each other and clamp the free end of the pipe to complete the overall fixation of the pipe. At this time, the ball connected to the moving frame 6 by the ranging rope is released. When the ball directly hits the baffle 12 set on one side of the vertical plate 14, it indicates that the test is passed; if the ball stops halfway, the position of the ball jam can be calculated according to the position of the ball sent back by the sensor and the release length of the ranging rope.

[0041] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
