Description

Technical Field

[0001] This utility model relates to the field of pipe testing technology, and in particular to a feeding device for a pipe pressure testing machine and a pipe pressure testing machine including the device. Background Technology

[0002] Pipe pressure testing machines are used to test the strength of pipes and check for cracks, leaks, etc. Existing pipe pressure testing machines typically test multiple pipes lined up in sequence. If a defective pipe is detected, it is marked, and then during unloading, good and defective pipes are transported separately to different hoppers.

[0003] However, existing pipe pressure testing machines require pipes to be fed one by one into the feeding device after pressure testing to separate good and defective pipes and transport them to different hoppers. Furthermore, existing pipe pressure testing machines tend to feed two or more consecutive pipes into the same hopper, easily leading to confusion in the screening of good and defective pipes, requiring rework. Therefore, existing pipe pressure testing machines have low feeding efficiency, which is detrimental to improving production efficiency. Utility Model Content

[0004] The main purpose of this utility model is to propose a feeding device for a pipe pressure testing machine, which aims to solve the technical problem that the feeding efficiency of the pipe pressure testing machine in the prior art is not high enough.

[0005] To achieve the above objectives, this utility model proposes a feeding device for a pipe pressure testing machine, including a feeding frame and a first and a second hopper mounted on the feeding frame. The feeding frame includes a fixed feeding section and a movable feeding section. The fixed feeding section, the second hopper, and the first hopper are arranged sequentially. The fixed feeding section is provided with a first feeding slope, and the movable feeding section is provided with a second feeding slope. The first feeding slope, the second feeding slope, and the first hopper are connected sequentially. The movable feeding section is movably mounted on the fixed feeding section, which can disconnect the first feeding slope and the first hopper and connect the first feeding slope and the second hopper. The fixed feeding section has a baffle and a lifting device on the side near the second hopper. The lifting device is used to lift the pipe blocked by the baffle so that it passes over the baffle and moves the pipe to the first or second hopper.

[0006] The beneficial effects of this utility model are as follows: In the feeding device of this utility model, multiple pipes can be blocked by baffles and arranged in sequence. Then, the lifting device lifts the multiple pipes one by one and conveys them downwards over the baffles. When conveying good products, the second feeding slope connects the first feeding slope and the first hopper, so that the pipes that have passed the baffles can be conveyed into the first hopper through the second feeding slope. When conveying defective products, the moving feeding part moves away to connect the first feeding slope with the second hopper, so that the pipes that have passed the baffles can fall into the second hopper. With this setting, multiple pipes after pressure testing can enter the feeding rack together, which helps to shorten the feeding time and more accurately screen good and defective products, reduce rework, and improve the efficiency of feeding and screening.

[0007] Preferably, the top material device includes a top material drive device and a top material component connected by a transmission. The top material component is provided with a top material ramp. The top material drive device can drive the top material component to move upward, lift the pipe and make the pipe roll along the top material ramp, so that the pipe rolls down into the second hopper or onto the second discharge ramp, which helps to improve the discharge efficiency.

[0008] Preferably, the baffle is located on the side of the fixed feeding section via the first adjusting device. The position of the baffle can be adjusted in the extension direction of the first feeding slope via the first adjusting device so that the feeding device only lifts the pipe closest to the baffle, making the screening of good and bad products more accurate, which is conducive to improving feeding efficiency and expanding the applicability of the feeding device.

[0009] Preferably, a guide rail and a first driving device are provided on the side of the fixed feeding part. The guide rail extends along the arrangement direction of the fixed feeding part and the second hopper. The movable feeding part is locked on the guide rail and can move along the guide rail. The first driving device is connected to the movable feeding part in a transmission manner, which can drive the movable feeding part to move away from or towards the first hopper. This is beneficial to improving the automation level of the feeding device, thereby improving the feeding efficiency.

[0010] Preferably, a support column is provided between the first and second material bins, and a supporting roller is provided on the support column. The supporting roller is used to support the moving material unloading part, ensuring that the moving material unloading part can extend smoothly and maintain a stable position. It also helps to extend the service life of the moving material unloading part and reduce the maintenance frequency.

[0011] Preferably, the feeding device further includes a pushing device, which is located on the side of the fixed feeding part away from the second hopper. The pushing device includes a pushing drive device and a pushing component connected by transmission. The pushing component has a pushing surface on the side near the fixed feeding part. A limiting rod is provided on the pushing surface. When pushing, the limiting rod is located on the upper side of the pipe to prevent the pipes from stacking, which is conducive to accurately feeding defective products into the second hopper for screening.

[0012] Preferably, a limiting plate is provided above the fixed feeding part, and the extending direction of the limiting plate is the same as the extending direction of the first feeding slope. When feeding, the pipe passes between the limiting plate and the first feeding slope. The limiting plate can prevent the pipe from stacking and further improve the accuracy of pipe screening.

[0013] Preferably, the feeding device further includes a mounting frame, and the limiting plate is mounted on the mounting frame via a second adjusting device. The second adjusting device includes an adjusting screw rotatably connected to the mounting frame and an adjusting screw block connected to the limiting plate. The adjusting screw block is provided with an adjusting screw hole, and the adjusting screw is spirally connected to the adjusting screw hole. This allows the limiting plate to move away from or closer to the first feeding slope, enabling the feeding device to adapt to feeding pipes of different diameters and thus expanding the applicability of the feeding device.

[0014] Preferably, the feeding device further includes a feeding rod communicating with the first feeding slope. The feeding rod is provided with a hinged section connecting the fixed feeding part and a movable end connecting the pressure measuring device of the pipe pressure measuring machine. The hinged section is hinged to the fixed feeding part through a rotating shaft. The feeding frame is provided with a rotary drive cylinder that is connected to the rotating shaft. The rotary drive cylinder can drive the rotating shaft to rotate, thereby driving the movable end of the feeding rod to move up and down, which can form a pedestrian passage between the pressure measuring device and the fixed feeding part for technicians to pass through, facilitating the maintenance of the pipe feeding machine.

[0015] This utility model also discloses a pipe pressure testing machine, including the feeding device of the above-mentioned pipe pressure testing machine. Attached Figure Description

[0023] like Figures 1 to 5As shown, a feeding device for a pipe pressure testing machine includes a feeding frame 1 and a first hopper 2 and a second hopper 3 disposed on the feeding frame 1. The feeding frame 1 includes a fixed feeding section 11 and a movable feeding section 12. The fixed feeding section 11, the second hopper 3, and the first hopper 2 are arranged sequentially. The fixed feeding section 11 is provided with a first feeding slope 111, and the movable feeding section 12 is provided with a second feeding slope 121. The first feeding slope 111, the second feeding slope 121, and the first hopper 2... The movable feeding section 12 is movably mounted on the fixed feeding section 11, which can disconnect the first feeding slope 111 and the first hopper 2 and connect the first feeding slope 111 and the second hopper 3. The fixed feeding section 11 is provided with a baffle 4 and a lifting device 5 on the side near the second hopper 3. The lifting device 5 is used to lift the pipe 30 blocked by the baffle 4 so that it passes over the baffle 4 and moves the pipe 30 to the first hopper 2 or the second hopper 3.

[0024] In this embodiment, the feeding device allows multiple pipes 30 to be blocked by baffles 4 and arranged sequentially. Then, the lifting device 5 lifts the pipes 30 one by one and transports them downwards past the baffles 4. When conveying good products, the second feeding ramp 121 connects the first feeding ramp 111 and the first hopper 2, allowing the pipes 30 that have passed the baffles 4 to be transported into the first hopper 2 via the second feeding ramp 121. When conveying defective products, the moving feeding part 12 moves away, connecting the first feeding ramp 111 with the second hopper 3, allowing the pipes 30 that have passed the baffles 4 to fall into the second hopper 3. This configuration allows multiple pipes 30 after pressure testing to enter the feeding rack 1 together, which helps shorten feeding time and allows for more accurate screening of good and defective products, reducing rework and improving feeding and screening efficiency.

[0025] In some specific embodiments, reference is made to Figure 1 and Figure 2 The top material device 5 includes a top material drive device and a top material component 51 connected by a transmission. The top material component 51 is provided with a top material ramp 511. The top material drive device can drive the top material component 51 to move upward, lift the pipe 30 and make the pipe 30 roll along the top material ramp 511, so that the pipe 30 rolls down into the second hopper 3 or onto the second discharge ramp 121.

[0026] In this embodiment, a top material ramp 511 is provided on the top material component 51, so that the pipe 30 being pushed up stays close to the baffle 4 during the upward process. After just passing the baffle 4, it can be conveyed downward under the action of gravity, without the need to set up an additional pipe pushing device to push the pipe 30 down, which helps to improve the material feeding efficiency.

[0027] Furthermore, the rear side of the ejector component 51 intersects with the ejector ramp 511 to form an ejector tip 512. During ejection, if, due to errors or operational mistakes, the ejector tip 512 hits the second pipe 30 closest to the baffle 4, the contact area between the ejector tip 512 and the pipe 30 is too small, causing the pipe 30 to quickly fall back onto the first discharge ramp 111. This avoids the situation where the pipe 30 is ejected too high and then falls, damaging the first discharge ramp 111 and subsequent pipes 30, or causing the pipes 30 to stack. Therefore, the ejector tip 512 also helps to improve discharge efficiency.

[0028] In some specific embodiments, reference is made to Figure 1 and Figure 2 The baffle 4 is located on the side of the fixed feeding part 11 via the first adjusting device 41. The position of the baffle 4 can be adjusted in the extension direction of the first feeding slope 111 by the first adjusting device 41 so that the top material device 5 only lifts the pipe 30 closest to the baffle 4.

[0029] Specifically, the first adjustment device 41 can be a cylinder, a "motor + lead screw and nut" or other forms, as long as it can adjust the position of the baffle 4 in the extension direction of the first feeding slope 111 and fix the position of the baffle 4 after adjustment.

[0030] In this embodiment, since the top material 51 only moves up and down, the first adjustment device 41 can adjust the distance between the rear side of the top material 51 and the baffle 4, thereby adapting to the feeding of pipes 30 of different diameters. This ensures that the top material device 5 will only lift the pipe 30 closest to the baffle 4 each time, making the screening of good and bad products more accurate, which is beneficial to improving feeding efficiency and expanding the applicability of the feeding device.

[0031] In some specific embodiments, reference is made to Figure 1 The fixed feeding part 11 is provided with a guide rail 7 and a first driving device 6 on its side. The guide rail 7 extends along the arrangement direction of the fixed feeding part 11 and the second hopper 3. The movable feeding part 12 is mounted on the guide rail 7 and can move along the guide rail 7. The first driving device 6 is connected to the movable feeding part 12 in a transmission manner, and can drive the movable feeding part 12 to move away from or towards the first hopper 2.

[0032] Specifically, the first drive device 6 employs a cylinder. When feeding good products, the cylinder of the first drive device 6 keeps the piston rod extended, so that the second feeding ramp 121 connects the first feeding ramp 111 and the first hopper 2. When feeding defective products, the cylinder of the first drive device 6 retracts, causing the moving feeding part 12 to retract and exit the second hopper 3—preferably retracting the moving feeding part 12 to the rear side of the baffle 4, so that the first feeding ramp 111 and the second hopper 3 are connected. However, due to the retraction of the moving feeding part 12, the first hopper 2 cannot connect to the first feeding ramp 111, so the pipe 30 cannot be fed into the first hopper 2. By driving the extension and retraction of the moving feeding part 12 through the first drive device 6, the feeding of the pipe 30 into the first hopper 2 or the second hopper 3 is controlled, thereby screening good and defective products, which helps to improve the automation level of the feeding device and thus improve the feeding efficiency.

[0033] In some specific embodiments, reference is made to Figure 1 A support column 13 is provided between the first hopper 2 and the second hopper 3. The support column 13 is provided with a supporting roller 122, which is used to support the moving unloading part 12.

[0034] The supporting roller 122 is used to support the front end of the moving unloading part 12 when it extends, so that the moving unloading part 12 can remain stable in position when it is subjected to falling pipe 30. The roller is set as a supporting structure so that even if the front end of the moving unloading part 12 is slightly lower than the upper side of the supporting roller 122 during the forward movement, it can still move smoothly to the upper side of the supporting roller 122 by the rolling action of the supporting roller 122. This ensures that the moving unloading part 12 can extend smoothly and maintain a stable position, and also helps to extend the service life of the moving unloading part 12 and reduce the maintenance frequency.

[0035] In some specific embodiments, reference is made to Figure 3 and Figure 5 The feeding device also includes a pushing device 8, which is located on the side of the fixed feeding part 11 away from the second hopper 3. The pushing device 8 includes a pushing drive device and a pushing component 81 connected by transmission. The pushing component 81 has a pushing surface 811 on the side close to the fixed feeding part 11. A limiting rod 82 is provided on the pushing surface 811. When pushing, the limiting rod 82 is located on the upper side of the pipe 30 to prevent the pipes 30 from being stacked.

[0036] Specifically, in the pipe pressure testing machine, the pressure testing device 20 is located on the side of the fixed feeding section 11 away from the second hopper 3. Before the pressure testing device 20 completes the pressure testing process, the pushing device 8 is located on the side of the pressure testing device 20 away from the fixed feeding section 11; after the pressure testing device 20 completes the pressure testing process, the pushing device 8 moves forward and pushes multiple pipes 30 on the pressure testing device 20 onto the fixed feeding section 11. When the pushing device 8 moves forward, the limiting rod 82 is located on the upper side of the pipe 30. In this embodiment, the distance between the limiting rod 82 and the pipe support surface of the pressure testing device 20 can only accommodate one pipe 30. Therefore, the setting of the limiting rod 82 can prevent the pipes 30 from stacking during the pushing process, thereby ensuring that the order of defective products among multiple pipes 30 remains unchanged during the feeding process, and enabling the defective products to be accurately fed into the second hopper 3 for screening.

[0037] In some specific embodiments, reference is made to Figure 4 and Figure 5 A limiting plate 9 is provided above the fixed feeding part 11. The extension direction of the limiting plate 9 is the same as the extension direction of the first feeding slope 111. When feeding, the pipe 30 passes between the limiting plate 9 and the first feeding slope 111. The limiting plate 9 can prevent the pipe 30 from being stacked.

[0038] A limiting plate 9 is also provided above the first discharge slope 111. When the pipe 30 enters the first discharge slope 111, due to its high speed, it is easy for the pipe 30 to stack after being blocked by the baffle 4. Therefore, the limiting plate 9 is provided. The distance between the limiting plate 9 and the first discharge slope 111 can only accommodate one pipe 30, to prevent the pipe 30 from stacking on the first discharge slope 111, and to further improve the accuracy of the screening of the pipe 30.

[0039] In some specific embodiments, reference is made to Figure 4 and Figure 5 The feeding device also includes a mounting frame 92. The limiting plate 9 is mounted on the mounting frame 92 via a second adjusting device 91. The second adjusting device 91 includes an adjusting screw 911 rotatably connected to the mounting frame 92 and an adjusting screw block 912 connected to the limiting plate 9. The adjusting screw block 912 is provided with an adjusting screw hole, and the adjusting screw 911 is spirally connected to the adjusting screw hole, which can drive the limiting plate 9 away from or closer to the first feeding slope 111.

[0040] The second adjustment device 91 can adjust the distance between the limiting plate 9 and the first feeding slope 111, thereby accommodating the feeding of pipes 30 of different diameters and expanding the applicability of the feeding device.

[0041] In some specific embodiments, reference is made to Figure 4The feeding device also includes a feeding rod 10 connected to the first feeding slope 111. The feeding rod 10 is provided with a hinged section that connects to the fixed feeding part 11 and a movable end 102 that connects to the pressure testing device 20 of the pipe pressure testing machine. The hinged section is hinged to the fixed feeding part 11 through a rotating shaft 103. The feeding frame 1 is provided with a rotary drive cylinder 104 that is connected to the rotating shaft 103. The rotary drive cylinder 104 can drive the rotating shaft 103 to rotate, thereby driving the movable end 102 of the feeding rod 10 to move up and down.

[0042] The feeding rod 10 is a structure used to connect the pressure measuring device 20 and the fixed feeding part 11, ensuring that the pipe 30 can move smoothly onto the first feeding slope 111. The limiting plate 9 is located on the upper side of the feeding rod 10 and the first feeding slope 111. The feeding device includes at least two feeding racks 1, with both ends of the rotating shaft 103 rotatably connected to the two feeding racks 1. The bottom of the rotating drive cylinder 104 is hinged to the feeding rack 1. The piston rod of the rotating drive cylinder 104 is connected to the rotating shaft 103 through a connecting rod 1041. One end of the connecting rod 1041 is rotatably connected to the piston rod of the rotating drive cylinder 104, and the other end is fixedly connected to the rotating shaft 103. When the piston rod of the rotating drive cylinder 104 extends, it drives the rotating shaft 103 to rotate, thereby causing the movable end 102 of the feeding rod 10 to rise, forming a passageway between the pressure measuring device 20 and the fixed feeding part 11 for technicians to pass through and facilitate maintenance of the pipe feeding machine.

[0043] This embodiment also discloses a pipe pressure testing machine, see reference. Figure 5 This includes the feeding device of the aforementioned pipe pressure testing machine.

All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
