Detailed implementation manner

[0021] In order to better understand the purpose, structure and function of the present invention, the following further describes in detail a bent pipe detection device for air conditioner equipment installation according to the present invention with reference to the accompanying drawings.

[0022] As Figures 1 to 6 shown, a bent pipe detection device for air conditioner equipment installation according to the present invention includes a water tank 1, a telescopic device provided on the water tank 1 through a bracket 2, a frame 4 provided on the telescopic end of the telescopic device, and a support plate 5 provided inside the frame 4. A detection component for detecting the bent pipe and a clamping component for fixing the bent pipe are provided on the support plate 5. The bent pipe to be detected is fixed through the clamping component, and then the frame 4 and the bent pipe fixed on the clamping component are driven by the telescopic device to extend into the water tank 1, and the bent pipe is detected through the detection component. Among them, the detection component is rotatably arranged with the support plate 5 to facilitate the adjustment of the detection component on the support plate 5.

[0023] Specifically, the bracket 2 is ∩-shaped, the telescopic device is located on the inner top surface of the bracket 2, and the telescopic device is preferably an electric push rod 3 connected to an external power supply. The telescopic end of the electric push rod 3 is arranged downward, and the frame 4 is arranged on the telescopic end of the electric push rod 3. The frame 4 is composed of a ∩-shaped frame body and two extension plates arranged at the bottom end of the ∩-shaped frame body, and the two extension plates are arranged oppositely. The support plate 5 is arranged between the two extension plates and is used to connect the two extension plates. It should be noted that in order to prevent the frame 4 from shifting, the frame 4 is slidably arranged with the water tank 1, so that the water tank 1 can limit the frame 4.

[0024] The clamping component for fixing the bent pipe includes a placing table 6 provided on the support plate 5, a first cylinder 7 provided on the inner top surface of the frame 4. The first cylinder 7 is connected to an external air pump, and the air pump is arranged on the outer wall of the water tank 1. At the same time, a pressing plate 8 is provided at the telescopic end of the first cylinder 7. The bent pipe to be detected can be placed on the placing table 6, and then the first cylinder 7 is started. The first cylinder 7 will clamp and fix the bent pipe placed on the placing table 6 through the pressing plate 8, so that the detection component can perform a sealing detection on the fixed bent pipe.

[0025] There are two detection components for detecting the sealing performance of bent pipes. Each detection component includes a slider 9 slidably disposed on a support disk 5, a boss 11 rotatably disposed on the slider 9, and a fixing ring 10 disposed on the slider 9. The boss 11 is located within the fixing ring 10 and is rotatably arranged therewith. The boss 11 and the fixing ring 10 are connected by a locking portion. A second cylinder 13 connected to an external air pump is provided on the boss 11 through a support seat 12, and a top disk 14 is provided at the telescopic end of the second cylinder 13. An air hole is formed in the top disk 14 of one of the detection components, and a nozzle 15 is communicated with one end of the air hole in the top disk 14, and the other end of the air hole is communicated with a connecting pipe 16. The connecting pipe 16 is communicated with the external air pump, and a limiting member cooperating with the support disk 5 is provided on the slider 9.

[0026] After the bent pipe is fixed between the placing table 6 and the pressing plate 8, according to the bending angle of the bent pipe, the slider 9 is rotated to rotate the corresponding detection component to an appropriate position on the support disk 5, and the slider 9 is fixed in position on the support disk 5 by using the limiting member. Then, the locking portion is used to adjust the angle of the boss 11 in the fixing ring 10 so that the top disk 14 corresponds to the port of the bent pipe. Then, the second cylinder 13 is started, and the second cylinder 13 pushes the top disk 14 to move towards the port of the bent pipe, so that the top disk 14 abuts against the bent pipe and seals it, and the nozzle 15 inserted into the bent pipe blows the gas in the external air pump into the bent pipe. Then, the first electric push rod 3 is started, and the first electric push rod 3 extends the components on the support disk 5 and the bent pipe fixed on the clamping component into the water in the water tank 1 through the frame 4, and it is determined whether the bent pipe is damaged by observing whether there are bubbles emerging in the water. It should be noted that a rubber pad is provided on the top disk 14, and the nozzle 15 penetrates through the rubber pad, and the sealing performance between the top disk 14 and the bent pipe can be improved through the rubber pad.

[0027] Specifically, an annular groove is formed on the support disk 5, and the slider 9 is arc-shaped corresponding to the annular groove (i.e., the slider 9 can rotate around the center of the support disk 5 on the support disk 5). And in order to facilitate the disassembly and assembly of the slider 9 on the support disk 5, the support disk 5 is composed of a tray 51 and two cover plates 52, and the tray 51 and the cover plates 52 are connected by bolts. Among them, the annular groove is formed on the tray 51. After the slider 9 is placed in the annular groove, the two cover plates 52 are respectively installed on the tray 51 and fixed with bolts.

[0028] The limiting member for fixing the slider 9 includes a threaded rod 17 threadedly connected to the slider 9, and the threaded rod 17 is arranged along the axis of the support disc 5. A threaded hole adapted to the threaded rod 17 is provided in the slider 9, and the threaded hole in the slider 9 is a through hole. A first handwheel 18 is provided at the top end of the threaded rod 17. When the first handwheel 18 is rotated, the first handwheel 18 will drive the threaded rod 17 to rotate, so that the bottom surface of the threaded rod 17 abuts against the annular groove of the support disc 5 to form a frictional force, so as to achieve the fixing effect of the slider 9 on the support disc 5. When the first handwheel 18 is rotated in the reverse direction, the threaded rod 17 will be disengaged from the contact with the support disc 5, so as to push the slider 9 to rotate on the support disc 5.

[0029] The locking part for adjusting the rib includes a connecting plate 19 provided on the circumference of the fixed ring 10, support columns 20 provided at both ends of the top surface of the connecting plate 19, and a worm 21 rotatably provided between the two support columns 20. And a second handwheel 22 is provided at one end of the worm 21. At the same time, a worm gear 23 is sleeved on the boss 11, and the worm 21 and the worm gear 23 are rotatably arranged. When the second handwheel 22 is rotated, the second handwheel 22 will drive the worm 21 to rotate, the rotation of the worm 21 will drive the worm gear 23 meshed with it to rotate, and the rotation of the worm gear 23 will drive the boss 11 connected to it to rotate, and the second cylinder 13 on the boss 11 will also rotate under the action of the support seat 12, and finally the pressing disc on the second cylinder 13 will be aligned with the port of the bent pipe.

[0030] Preferably, in order to facilitate the positioning of bent pipes with different bending angles on the placing table 6. A plurality of mounting holes 25 are rectangularly distributed on the placing table 6, and a stud 27 and a spring 26 are provided in the mounting hole 25. The spring 26 is located below the stud 27, and the stud 27 is slidably arranged in the mounting hole 25. And a cover 24 is detachably mounted on the placing table 6 through a connecting member (bolt or screw), and through holes are provided in the cover 24 corresponding to the positions of the studs 27, and the studs 27 and the through holes are slidably arranged. When the bent pipe is placed on the placing table 6, the bent pipe can be pressed down, and the stud 27 in contact with the bent pipe will move downward and compress the spring 26, so as to form a pipe groove adapted to the bent pipe in each stud 27 on the placing table 6.

[0031] In order to fix the position of the pipe groove formed on the stud 27, jack holes 28 are provided on both sides of the side-by-side mounting holes 25 on the placing table 6, and plug rods 29 are inserted into the jack holes 28. The plug rods 29 cooperate with the stud 27, and the outer ends of the plug rods 29 are connected by a strip plate 30. For easy understanding, the stud 27 is divided into a rod 271 and a cap 272. The jack holes 28 on the placing table 6 are specifically located outside the rod 271, and the dimension between the inner walls of the jack holes 28 on both sides of the mounting hole 25 is smaller than the diameter dimension of the rod 271. At the same time, rubber pads are provided on the inner walls of the plug rods 29 on both sides of the mounting hole 25. After the stud 27 is pressed down and inserted into the plug rod 29, friction will be generated between the rubber pad on the inner wall of the plug rod 29 and the rod 271 of the stud 27. When the pressed-down stud 27 is released, the stud 27 will be limited by the plug rod 29.

[0032] As Figure 4 and Figure 6 shown, a limiting member is provided on the side wall of the placing table 6, and the limiting member includes a clamping block 31 rotatably arranged on the side wall of the placing table 6 through a rotating shaft. The clamping block 31 cooperates with the strip plate 30. By pushing the clamping block 31, the clamping block 31 rotates through the rotating shaft, so that the limiting of the strip plate 30 by the clamping block 31 is released, and the plug rod 29 on the strip plate 30 can be taken out of the jack hole 28. When it is necessary to fix the plug rod 29, the clamping block 31 can be rotated in the reverse direction, and the clamping block 31 is rotated downward so that the clamping block 31 contacts the strip plate 30, and the limiting of the strip plate 30 by the clamping block 31 can be realized.

[0033] Usage method: Place the elbow pipe to be detected on each stud 27, and press down the elbow pipe. The stud 27 in contact with the elbow pipe will descend. Insert the plug rod 29 into the jack hole 28 to contact the descended stud 27 and generate frictional force, so that the stud 27 on the placing table 6 forms a pipe groove adapted to the elbow pipe. Then start the first cylinder 7, and the first cylinder 7 drives the pressing plate 8 to descend to clamp and fix the elbow pipe placed on the stud 27. Then rotate the slider 9 on the support disk 5 to an appropriate position, and use the locking part to align the top disk 14 on the second cylinder 13 with the port of the elbow pipe. Start the second cylinder 13, and the second cylinder 13 drives the top disk 14 to seal the elbow pipe. Then the air nozzle 15 injects high-pressure gas into the spray pipe. Finally, start the electric push rod 3, and the electric push rod 3 enters the water tank 1 through the components on the frame 4 and the elbow pipe to be detected. Whether the elbow pipe leaks can be judged by observing whether bubbles are ejected from the elbow pipe.
