Description

Technical Field

[0001] The present application relates to the field of pipeline detection devices, and particularly to a five - unit water pressure testing device. Background Art

[0002] The water pressure test is an important quality inspection method to ensure the safe and reliable use of steel pipes in the future. In this process, water is injected into the steel pipe and maintained at a specified pressure for a period of time to observe whether the steel pipe leaks or breaks, so as to evaluate its performance. This test is not only a necessary link in the steel pipe manufacturing process, but also an indispensable step before installation and use.

[0003] Usually, when conducting a water pressure test, it is necessary to manually install the water pipes one by one, and then recycle the steel pipes after the water pressure test is completed. The operation is relatively complex and time - consuming, and the test operation efficiency is relatively low, so it needs to be improved. Content of the Utility Model

[0004] In order to improve the efficiency of pipeline testing, the present application provides a five - unit water pressure testing device.

[0005] The five - unit water pressure testing device provided by the present application adopts the following technical solutions:

[0006] A five - unit water pressure testing device includes testing machines on both sides. The two testing machines can approach each other. A collection water tank is arranged between the two testing machines. A clamping assembly is arranged above the collection water tank, and a blanking assembly is arranged above the collection water tank. The clamping assembly and the blanking assembly operate alternately to clamp the pipeline or guide the water pipe to blank.

[0007] By adopting the above - mentioned technical solution, when detecting the water pipe, the clamping assembly clamps the water pipe. One of the testing machines moves until both ends of the water pipe are inserted into the testing machines on both sides. When the detection is completed, the testing machines move away from each other, the clamping assembly releases the clamping of the water pipe, and the blanking assembly guides the water pipe to complete blanking. The use of the clamping assembly and the blanking assembly reduces the work items of the operator and improves the operation efficiency of detecting the water pipe.

[0008] Optionally, the clamping assembly includes a mounting frame, a first clamping plate and a second clamping plate. The mounting frame is installed on the top of the collection water tank. The first clamping plate and the second clamping plate are both installed on the top of the mounting frame along the width direction of the water pipe. A number of clamping grooves are sequentially formed on the top walls of the first clamping plate and the second clamping plate along the width direction of the water pipe. A clamping driving member is installed on the mounting frame, and the clamping driving member can drive the first clamping plate and / or the second clamping plate to move so that the first clamping plate and the second clamping plate approach each other.

[0009] Optionally, limiting grooves are formed in the inner side walls of the clamping grooves. The limiting grooves on the first clamping plate and the second clamping plate are arranged opposite to each other, and the opposite limiting grooves can approach each other.

[0010] Optionally, the inner side wall of the limiting groove close to the mounting frame is inclined downward and is smoothly connected to the bottom of the clamping groove.

[0011] By adopting the above technical solution, when it is necessary to detect a water pipe, an operator places the water pipe in the clamping grooves of the first clamping plate and the second clamping plate, and the clamping driving member drives the second clamping plate to move closer to the first clamping plate; at this time, the water pipe slowly moves into the limiting groove. When the water pipe is in contact with the inner wall of the limiting groove, the first clamping plate and the second clamping plate complete the limiting clamping of the water pipe. At this time, the testing machine tests the water pipe. After the test is completed, the blanking assembly performs blanking processing on the water pipe.

[0012] Optionally, the blanking assembly includes a mounting plate, a blanking plate, and a blanking driving member. The mounting plate is installed at the bottom of the collection water tank. The blanking driving member is embedded in the mounting plate. The blanking plate is installed on the blanking driving member. The blanking driving member drives the blanking plate to rise or fall; a plurality of inclined blocks are arranged on the blanking plate along the width direction of the collection water tank. The plurality of inclined blocks are arranged in the same direction, and a blanking moving area is formed between adjacent inclined blocks; an inclined surface is provided on the top wall of the first clamping plate or the second clamping plate. The inclination direction of the inclined surface is the same as the inclination direction of the inclined blocks; the lowest point of the inclined block can rise above the inclined surface, and the highest point of the inclined block can fall below the inclined surface.

[0013] Optionally, the height of the clamping plate with the inclined surface is higher than the height of the other clamping plate.

[0014] By adopting the above technical solution, after the detection is completed, the clamping driving member drives the second clamping plate away from the first clamping plate. At this time, the water pipe rolls down along the inclined wall of the limiting groove to the bottom wall of the clamping groove under the action of gravity; at this time, the blanking driving member drives the blanking plate to rise, and the water pipe rises from the limiting groove until it escapes from the limiting groove. At this time, the lowest point of the inclined block rises above the inclined surface, and the water pipe rolls along the inclination direction of the inclined block under the action of gravity. When the water pipe rolls and is in contact with the end wall of the adjacent inclined block, it stops rolling. At this time, the blanking driving member drives the blanking plate to descend. When the water pipe is placed on the inclined surface of the second clamping plate, the blanking plate continues to descend until the highest point of the inclined block falls below the inclined surface, and the water pipe rolls down along the inclined surface and rolls into the clamping groove under the action of gravity. Repeat the above actions to move the water pipe in the inclined direction.

[0015] Optionally, the blanking assembly further includes a collection belt. The collection belt is installed on the rack. The collection belt is recessed and is arranged lower than the blanking plate.

[0016] Optionally, a guide plate is provided between the collecting belt and the blanking plate, and the guide plate guides the pipe from the blanking plate to the collecting belt.

[0017] By adopting the above technical solution, the water pipe rolls down from the inclined block, rolls along the guide plate to the collecting belt and is collected.

[0018] To sum up, the present application includes at least one of the following beneficial technical effects:

[0019] 1. When detecting the water pipe, the clamping assembly clamps the water pipe, and one of the detectors moves until both ends of the water pipe are inserted into the detectors on both sides; when the detection is completed, the detectors move away from each other, the clamping assembly releases the clamping of the water pipe, and the blanking assembly guides the water pipe to complete blanking. The use of the clamping assembly and the blanking assembly reduces the work items of the operator and improves the operation efficiency of detecting the water pipe;

[0020] 2. When the detection is completed, the clamping driving member drives the second clamping plate away from the first clamping plate. At this time, the water pipe rolls down along the inclined wall of the limiting groove to the bottom wall of the clamping groove under the action of gravity; at this time, the blanking driving member drives the blanking plate to rise, and the water pipe rises from the limiting groove until it escapes from the limiting groove. At this time, the lowest point of the inclined block rises above the inclined surface, and the water pipe rolls along the inclined direction of the inclined block under the action of gravity. When the water pipe rolls and abuts against the end wall of the adjacent inclined block, it stops rolling. At this time, the blanking driving member drives the blanking plate to descend. When the water pipe is placed on the inclined surface of the second clamping plate, the blanking plate continues to descend until the highest point of the inclined block drops below the inclined surface, and the water pipe rolls and rolls into the clamping groove along the inclined surface under the action of gravity. Repeat the above actions so that the water pipe moves in the inclined direction. Description of the Drawings

[0025] The following further describes this application in detail with reference to the accompanying Figures 1-3 drawings.

[0026] An embodiment of this application discloses a five - unit water pressure testing device. Referring to Figure 1 , the five - unit water pressure testing device includes testing machines 1 on both sides, where one testing machine 1 is fixedly arranged, and the other testing machine 1 is movably arranged to move closer to or away from the fixed testing machine 1. A collection water tank 2 is arranged between the two testing machines 1, and the collection water tank 2 is installed on the ground. Above the collection water tank 2, a plurality of clamping components 3 and a plurality of blanking components 4 are installed. In this implementation, the plurality of clamping components 3 and the plurality of blanking components 4 are installed alternately, and the clamping components 3 and the blanking components 4 operate alternately to clamp the pipeline or guide the water pipe for blanking. On one side of the collection water tank 2 away from the blanking component 4, a loading rack 5 is arranged.

[0027] A plurality of water pipes are pre - placed on the loading rack 5, and the water pipes roll down to the clamping components 3 of the collection water tank 2 under the guidance of the loading rack 5; when detecting the water pipes, the clamping components 3 clamp the water pipes, and one of the testing machines moves until both ends of the water pipe are inserted into the testing machines on both sides; when the detection is completed, the testing machines move away from each other, the clamping components 3 release the clamping of the water pipes, and the blanking components 4 guide the water pipes to complete blanking; during the process of guiding blanking by the blanking components 4, the water pipes on the loading rack 5 roll down to the clamping components 3 of the collection water tank 2. The use of the clamping components 3 and the blanking components 4 reduces the work items of the operator and improves the operation efficiency of detecting the water pipes.

[0028] Referring to Figure 2 and Figure 3 , the clamping component 3 includes a mounting frame 31, the mounting frame 31 is installed on the top of the collection water tank 2, the length direction of the mounting frame 31 is parallel to the width direction of the water pipe, a first clamping plate 32 and a second clamping plate 33 are installed on the mounting frame 31, and the length directions of the first clamping plate 32 and the second clamping plate 33 are both consistent with the length direction of the mounting frame 31; on the top walls of the first clamping plate 32 and the second clamping plate 33, a plurality of clamping grooves 35 are sequentially formed along the width direction of the water pipe, and the clamping grooves 35 of the first clamping plate 32 and the clamping grooves 35 of the second clamping plate 33 are partially staggered.

[0029] A clamping driving member 34 is installed on the mounting frame 31, the clamping driving member 34 is a cylinder, and the clamping driving member 34 can drive the first clamping plate 32 and / or the second clamping plate 33 to move so that the first clamping plate 32 and the second clamping plate 33 approach each other; in this implementation, the clamping driving member 34 is connected to the second clamping plate 33. At this time, the first clamping plate 32 is fixed on the mounting frame 31, and the clamping driving member 34 is started to control the second clamping plate 33 to approach or move away from the first clamping plate 32.

[0030] Limiting grooves 36 are formed in the inner side walls of the clamping grooves 35. The limiting grooves 36 on the first clamping plate 32 are arranged opposite to the limiting grooves 36 on the second clamping plate 33, and the opposite limiting grooves 36 can approach each other. The limiting grooves 36 are inclined downwardly towards the inner side wall of the mounting frame 31 and are smoothly connected to the bottom of the clamping groove 35; in this embodiment, the limiting grooves 36 are triangular grooves.

[0031] In this embodiment, the height of the second clamping plate 33 is higher than that of the first clamping plate 32, and the top wall of the second clamping plate 33 is provided as an inclined surface 37.

[0032] When it is necessary to detect the water pipe, the operator places the water pipe in the clamping grooves 35 of the first clamping plate 32 and the second clamping plate 33, and the clamping driving member 34 drives the second clamping plate 33 to move closer to the first clamping plate 32; at this time, the water pipe slowly moves into the limiting groove 36. When the water pipe is in contact with the inner wall of the limiting groove 36, the first clamping plate 32 and the second clamping plate 33 complete the limiting clamping of the water pipe. At this time, the testing machine 1 tests the water pipe. After the test is completed, the blanking assembly 4 performs blanking processing on the water pipe.

[0033] Refer to Figure 2 and Figure 3 As shown in FIGS. and, the blanking assembly 4 includes a mounting plate 41. The mounting plate 41 is mounted on the top wall of the collection water tank 2 by bolts. The length direction of the mounting plate 41 is the same as the length direction of the mounting frame 31, and the mounting plate 41 is mounted on one side of the mounting frame 31; a blanking driving member 43 is mounted on the mounting plate 41. The blanking driving member 43 is a cylinder in this embodiment. The cylinder block of the blanking driving member 43 is mounted at the bottom of the mounting plate 41, and the piston rod of the blanking driving member 43 passes through the mounting plate 41 and is connected to a blanking plate 42. The blanking driving member 43 drives the blanking plate 42 to rise or fall.

[0034] A plurality of inclined blocks 421 are integrally formed on the blanking plate 42 along the width direction of the collection water tank 2. In this embodiment, the inclined blocks 421 are triangular in cross-section. The plurality of inclined blocks 421 are arranged in the same direction, and a blanking moving area is formed between adjacent inclined blocks 421. In this embodiment, the inclination direction of the inclined blocks 421 is the same as the inclination direction of the inclined surface 37 on the second clamping plate 33. The lowest point of the inclined blocks 421 can rise above the inclined surface 37, and the highest point of the inclined blocks 421 can fall below the inclined surface 37. And the inclined position of the inclined blocks 421 is staggered with the inclined surface 37 of the second clamping surface.

[0035] After the detection is completed, the clamping driving member 34 drives the second clamping plate 33 away from the first clamping plate 32. At this time, the water pipe rolls down along the inclined wall of the limiting groove 36 to the bottom wall of the clamping groove 35 under the action of gravity. At this time, the blanking driving member 43 drives the blanking plate 42 to rise, and the water pipe rises from the limiting groove 36 until it disengages from the limiting groove 36. At this time, the lowest point of the inclined block 421 rises above the inclined surface 37, and the water pipe rolls along the inclined direction of the inclined block 421 under the action of gravity. When the water pipe rolls and abuts against the end wall of the adjacent inclined block 421, it stops rolling. At this time, the blanking driving member 43 drives the blanking plate 42 to descend. When the water pipe is placed on the inclined surface 37 of the second clamping plate 33, the blanking plate 42 continues to descend until the highest point of the inclined block 421 drops below the inclined surface 37. The water pipe rolls along the inclined surface 37 and rolls into the clamping groove 35 under the action of gravity. Repeat the above actions to move the water pipe in the inclined direction. When the blanking plate 42 moves up and down, the detected water pipes are discharged, and at the same time, the water pipes to be detected on the loading rack 5 are sequentially moved into the clamping groove 35 of the second clamping plate 33.

[0036] Refer to Figure 1 , the blanking assembly 4 further includes a collecting belt 44. The collecting belt 44 is installed on the rack. The collecting belt 44 is recessed and is arranged lower than the blanking plate 42. A guiding plate 45 is arranged between the collecting belt 44 and the blanking plate 42. The guiding plate 45 is welded to the rack on one side of the collecting water tank 2. The guiding plate 45 guides the pipeline from the blanking plate 42 to the collecting belt 44.

[0037] The implementation principle of a five - joint water pressure testing device according to an embodiment of the present application is as follows: After the detection is completed, the clamping driving member 34 drives the second clamping plate 33 away from the first clamping plate 32. At this time, the water pipe rolls down along the inclined wall of the limiting groove 36 to the bottom wall of the clamping groove 35 under the action of gravity. At this time, the blanking driving member 43 drives the blanking plate 42 to rise, and the water pipe rises from the limiting groove 36 until it disengages from the limiting groove 36. At this time, the lowest point of the inclined block 421 rises above the inclined surface 37, and the water pipe rolls along the inclined direction of the inclined block 421 under the action of gravity. When the water pipe rolls and abuts against the end wall of the adjacent inclined block 421, it stops rolling. At this time, the blanking driving member 43 drives the blanking plate 42 to descend. When the water pipe is placed on the inclined surface 37 of the second clamping plate 33, the blanking plate 42 continues to descend until the highest point of the inclined block 421 drops below the inclined surface 37. The water pipe rolls along the inclined surface 37 and rolls into the clamping groove 35 under the action of gravity. Repeat the above actions to move the water pipe in the inclined direction. Finally, the water pipe rolls off the inclined block 421, rolls along the guiding plate 45 and is collected on the collecting belt 44. During the process of discharging the water pipe, the operator prepares the water pipes to be detected in the next round. Using the clamping assembly 3 and the blanking assembly 4 reduces the work items of the operator and improves the operation efficiency of detecting the water pipes.
