Description

Technical Field

[0001] The utility model belongs to the field of pressure pipelines, and in particular relates to a pressure pipeline detection device. Background Art

[0002] Pressure pipes are used to withstand high pressures and must have good sealing properties after production. Pressure pipes need to be tested for sealing properties after production. Currently, when testing the air tightness of pressure pipes, both ends of the pressure pipes are sealed with a pressure plate, and then gas is injected into the pressure pipe. The pressure gauge is used to observe whether the gas in the pressure pipe is reduced to test the air tightness of the pressure pipe. This method does not seal the pressure light tightly at both ends through the pressure plate, which affects the air tightness test effect. At the same time, the replacement of the pressure pipe is manual operation, which reduces work efficiency. Utility Model Content

[0019] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a pressure pipeline detection device of the utility model in conjunction with the accompanying drawings.

[0020] like Figures 1 to 4 As shown, a pressure pipeline detection device of the utility model includes a base 1, a bracket 2 and a pool 3 are arranged on the base 1, and the bracket 2 is ∩-shaped, and the pool 3 is located inside the bracket 2. A support block 4 is symmetrically arranged at its center in the bracket 2, that is, the support block 4 is arranged on two columns of the bracket 2, and a first electric push rod 5 with a telescopic end facing the support block 4 is arranged, and the first electric push rod 5 is connected to an external power supply for power supply. At the same time, a clamping assembly for clamping the pipeline is provided at the telescopic end of the first electric push rod 5, and a connecting pipe 8 connected to the air pump 22 on the base 1 is provided on the clamping assembly. After the pressure pipeline is clamped and fixed by the clamping assembly, the first electric push rod 5 is started, and the first electric push rod 5 drives the clamping assembly and the pressure pipeline fixed thereon to move toward the pool 3 until the pressure pipeline is immersed in the liquid of the pool 3 as a whole, and the air pump 22 inflates the pressure pipeline through the connecting pipe 8. If there is a leak in the pressure pipeline, bubbles will be generated in the pool 3. After the detection is completed, the pressure pipe on the clamping assembly is driven by the first electric push rod 5 to move upward to the initial position.

[0021] Specifically, the clamping assembly includes a hydraulic cylinder 6 disposed at the telescopic end of the first electric push rod 5, the hydraulic cylinder 6 is connected to a hydraulic pump 21 disposed on the base 1, and a top plate 7 is provided at the telescopic end of the hydraulic cylinder 6, a connecting pipe 8 is disposed on the top plate 7, and is coaxially disposed with the top plate 7, and a rubber pad is disposed on the inner wall of the top plate 7, so that when clamping the pressure pipe, the sealing between the top plate 7 and the pressure pipe can be increased. Preferably, a connecting ring 9 is further disposed at the free end of the top plate 7, and an air bag 91 is disposed on the inner wall of the connecting ring 9, and an air pipe 10 connected to the air bag 91 is connected to the outer wall of the connecting ring 9, and the air pipe 10 is connected to the air pump 22 disposed on the base 1. When the pressure pipe is clamped by the clamping assembly, the two ends of the pressure pipe will be inserted into the connecting ring 9 and contact the rubber pad on the top plate 7. Then, the air pump 22 is used to inflate the airbag 91, so that the airbag 91 can seal the two ends of the connecting pipe 8, so that a seal is formed between the airbag 91 and the pressure pipe to prevent the internal gas from leaking from both ends during the pressure pipe inspection. When the pressure pipe in the clamping assembly needs to be lowered, the telescopic end of the hydraulic cylinder 6 drives the top plate 7 to be retracted, so that the pressure pipe can be removed from the connecting ring 9.

[0022] In order to facilitate the installation of the pressure pipe on the clamping assembly, the bottom end of the hydraulic cylinder 6 is connected through a connecting plate 11, and a positioning plate 12 is provided on the connecting plate 11. The positioning plate 12 has an arc-shaped groove arranged along its length direction, which is convenient for the placement of the pressure pipe on the positioning plate 12. Of course, the arc-shaped groove on the positioning plate 12 can also be set as a V-shaped groove, which is also feasible, and no excessive restrictions are made here. In addition, the setting of the positioning plate 12 can increase the spacing between the pressure pipe placed on the positioning plate 12 and the connecting plate 11, making it convenient for the pressure pipe to enter the connecting ring 9.

[0023] As another preferred embodiment, a first support plate 17 and a second support plate 19 are inclined on the side wall of the pool 3, and the first support plate 17 is inclined downward toward the position away from the pool 3, while the second support plate 19 is inclined downward toward the side close to the pool 3, and a first baffle 18 is provided at the end of the first support plate 17 away from the pool 3, and a second baffle 20 is provided at the end of the second support plate 19 close to the pool 3. The pressure pipe to be tested can be placed on the second support plate 19, and the pressure pipe after the test is completed can be placed on the first support plate 17. In order to facilitate the replacement of the pressure pipe in the clamping assembly, a pick-up assembly 13 for lifting the pressure pipe in the clamping assembly is provided on the bracket 2, and a mounting frame 14 is provided on the bracket 2, and an adjustment device 15 cooperating with the pick-up assembly 13 is provided on the mounting frame 14.

[0024] like Figure 3 As shown, the adjusting device 15 includes a slide groove 152 opened along the length direction of the installation frame 14, and a slider 151 is slidably arranged in the slide groove 152, and a third electric push rod 16 is arranged at the bottom end of the slider 151 with a telescopic end facing downward, and the third electric push rod 16 is connected to an external power supply for power supply. At the same time, a screw rod 153 is also rotatably arranged in the slide groove 152, and the screw rod 153 is threadedly connected to the slider 151, and one end of the screw rod 153 penetrates the installation frame 14 and extends outward, and a motor 154 connected to the extended end of the screw rod 153 is arranged on one side of the installation frame 14. The screw rod 153 and the slider 151 are threadedly connected, so that a self-locking function can be generated between the screw rod 153 and the slider 151, so that when the screw rod 153 drives the components on the slider 151 to move, the load of the motor 154 when starting and stopping is reduced, and the service life of the motor 154 is increased. Specifically, the motor 154 is started, the motor 154 drives the screw 153 to rotate, the slider 151 threadedly connected to the screw 153 moves along the slide 152, and the components connected to the slider 151 move with the slider 151. Similarly, when the slider 151 needs to move toward the initial position, the motor 154 is controlled to rotate in the opposite direction, and the screw 153 rotates in the opposite direction with the motor 154. At this time, the slider 151 threadedly connected to the slider 151 will move toward the initial position, thereby realizing the reciprocating movement of the components on the slider 151 in the slide 152. Among them, the adjustment component can also be replaced with a push rod to meet the use requirements.

[0025] The pick-up assembly 13 for lifting and lowering the pressure pipe in the clamping assembly is arranged on the telescopic end of the third electric push rod 16. The pick-up assembly 13 includes a fixed plate 131 arranged at the telescopic end of the second electric push rod 136, and a support plate 132 is distributed on the periphery of the fixed plate 131. The two support plates 132 arranged along the length direction of the pressure pipe are symmetrically arranged. The support plates 132 are specifically H-shaped. Clamps 134 are slidably arranged at both ends of the support plates 132. There is a clamping gap between the clamps 134, and a friction plate 135 that can increase friction is arranged on the inner wall of the clamps 134. The arrangement of the friction plate 135 can also prevent the clamps 134 from damaging the surface of the pressure pipe. A fixing block 133 is also provided at the top of the support plate 132, and a second electric push rod 136 is symmetrically provided at the center of the fixing block 133. The second electric push rod 136 is connected to an external power supply, and the second electric push rod 136 is connected to the corresponding clamping plate 134. The second electric push rods 136 on the same group of support plates 132 are connected and used through a controller. For the convenience of subsequent understanding, the components on the two support plates 132 symmetrically provided on the fixing plate 131 are referred to as a group, and Figure 1 The support plate 132 located above the clamping pressure pipe in the clamping assembly is the first group of clamping parts, and the support plate 132 on the other side is the second group of clamping parts. Specifically, when the pressure pipe in the clamping assembly needs to be replaced, the third electric push rod 16 can be used to drive the picking assembly 13 to move downward, and when the picking assembly 13 moves downward, the pressure pipe fixed in the clamping assembly will enter the clamping gap of the clamping plate 134 of the first group of clamping parts. The pressure pipe to be tested on the second support plate 19 near the pool 3 is located in the gap of the clamping plate 134 of the second group of clamping parts, and then the second electric push rod 136 is controlled, and the second electric push rod 136 drives the two clamping plates 134 on the same support plate 132 to move closer to each other, and clamps the corresponding pressure pipe. After that, the third electric push rod 16 is started to lift the picking assembly 13 upward, and then the adjusting device 15 is started to drive the picking assembly 13 to move toward the first supporting plate 17 through the third electric push rod 16. When the pressure pipe to be tested on the second group of clamping parts is located above the positioning plate 12, it stops. Then the third electric push rod 16 drives the picking assembly 13 to move downward, and then the second electric push rod 136 is controlled to work, so that the two clamping plates 134 move away from each other. The pressure pipe on the first group of clamping parts falls on the first supporting plate 17, and the pressure pipe on the second group of clamping parts falls on the positioning plate 12. Then, the picking assembly 13 is raised upward by the third electric push rod 16, and then the third electric push rod 16 and the picking assembly 13 are driven to move to the initial position through the adjusting device 15. In this reciprocating manner, the replacement of the pressure pipe after the inspection is completed can be completed. The operation is simple and convenient to use, and the work efficiency is improved.

[0026] Method of use: place the pressure pipe to be inspected on the second support plate 19 and block it with the second baffle 20, then use the third electric push rod 16 to drive the picking assembly 13 to clamp the pressure pipe to be inspected on the second support plate 19, and clamp the pressure pipe placed on the positioning plate 12 at the same time, then start the third electric push rod 16 to drive the picking assembly 13 to move upward, and under the action of the adjusting device 15, the picking assembly 13 is driven by the third electric push rod 16 to move toward the first support plate 17, then the picking assembly 13 is driven by the third electric push rod 16 to move downward, and then the picking assembly 13 releases the clamped pressure pipe, and the pressure pipe to be inspected will fall on the positioning plate 12, and the pressure pipe after inspection will fall directly on the first support plate 17, and then the third electric push rod 16 drives the picking assembly 13 to rise, and then the adjusting device 15 drives the third electric push rod 16 and the picking assembly 13 to move to the initial position.
