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 simultaneously in the same batch. Before testing, technicians need to load and arrange the pipes in sequence. However, in practice, technicians usually have to wait for the previous batch of pipes to be tested before loading the next batch onto the testing device, arranging the pipes one by one. This method results in a slow pipe turnover rate on the pressure testing machine, which is detrimental to improving testing and production efficiency. Utility Model Content

[0003] 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 speed of the pipe pressure testing machine in the prior art is not fast enough.

[0004] To achieve the above objectives, this utility model proposes a feeding device for a pipe pressure testing machine, including a feeding rack, a feeding section, a fixed pipe arrangement structure, a movable pipe arrangement structure, and a first driving device. The feeding rack has at least two fixed pipe arrangement structures, each with multiple sequentially arranged first pipe placement slots, with each slot corresponding to the previous one. The feeding rack also has at least two movable pipe arrangement structures, each with multiple sequentially arranged second pipe placement slots, and the movable pipe arrangement structures are connected to the first driving device. The first driving device and the movable pipe arrangement structures can sequentially arrange the pipes from the feeding section onto the multiple first pipe placement slots of the fixed pipe arrangement structure, or simultaneously feed the pipes sequentially arranged on the multiple first pipe placement slots onto the pressure testing device of the pipe pressure testing machine.

[0005] The beneficial effects of this utility model are as follows: The feeding device of this utility model includes a fixed pipe arrangement structure with multiple first pipe placement slots, and a movable pipe arrangement structure. While the pressure testing device of the pipe pressure testing machine is testing the previous batch of pipes, the next batch of pipes to be tested can be pre-arranged on the fixed pipe arrangement structure. After the pressure testing of the previous batch of pipes is completed, the movable pipe arrangement structure then feeds the arranged pipes to be tested onto the pressure testing device. This feeding device utilizes the time of the previous batch of pipes for pre-arranging the next batch of pipes, which helps improve feeding efficiency, testing efficiency, and production efficiency.

[0006] Preferably, the feeding section includes a first feeding ramp, and a first baffle for stopping the pipe is provided between the first feeding ramp and the fixed pipe arrangement structure.

[0021] like Figures 1 to 4 As shown, a feeding device for a pipe pressure testing machine includes a feeding rack 1. The feeding rack 1 is provided with a feeding section 2, a fixed pipe arrangement structure 3, a movable pipe arrangement structure 4, and a first driving device 5. The feeding rack 1 is provided with at least two fixed pipe arrangement structures 3, and the fixed pipe arrangement structures 3 are provided with a plurality of first pipe placement slots 31 arranged in sequence, with the plurality of first pipe placement slots 31 on the two fixed pipe arrangement structures 3 corresponding one-to-one. The feeding rack 1 is provided with at least two movable pipe arrangement structures 4, and the plurality of second pipe placement slots 41 on the two movable fixed pipe arrangement structures are corresponding one-to-one. The movable pipe arrangement structures 4 and the first driving device 5 are connected in a transmission manner. The first driving device 5 and the movable pipe arrangement structures 4 can arrange the pipes on the feeding section 2 in sequence on the plurality of first pipe placement slots 31 of the fixed pipe arrangement structure 3, or can simultaneously feed the pipes arranged in the plurality of first pipe placement slots 31 to the pressure testing device 10 of the pipe pressure testing machine.

[0022] The feeding device in this embodiment includes a fixed pipe arrangement structure 3 with multiple first pipe placement slots 31, and a movable pipe arrangement structure 4. While the pressure testing device 10 of the pipe pressure testing machine is testing the previous batch of pipes, the next batch of pipes to be tested can be pre-arranged on the fixed pipe arrangement structure 3. After the previous batch of pipes has finished testing, the movable pipe arrangement structure 4 then feeds the arranged pipes to be tested onto the pressure testing device 10. This feeding device in this embodiment utilizes the time of the previous batch of pipes' pressure testing to pre-arrange the next batch of pipes, which helps improve feeding efficiency, testing efficiency, and production efficiency.

[0023] In some specific embodiments, reference is made to Figure 1 and Figure 2The feeding section 2 includes a first feeding ramp 21. A first baffle 11 for stopping the pipes is provided between the first feeding ramp 21 and the fixed pipe arrangement structure 3. The loading rack 1 is provided with an initial pipe placement position 321, a first pipe placement position 322, and a second pipe placement position 323. The initial pipe placement position 321 is located behind the first baffle 11. The first pipe placement position 322 is located on the first first pipe placement groove 31 closest to the first baffle 11. The second pipe placement position 323 is located on the second first pipe placement groove 31 closest to the first baffle 11. The movable pipe arrangement structure 4 is provided with a plurality of second pipe placement grooves 41 arranged in sequence. The arrangement method is consistent with the arrangement method of multiple first pipe placement slots 31 on the fixed pipe arrangement structure 3. The movable pipe arrangement structure 4 is provided with a first pipe moving position 421 and a second pipe moving position 422. The first pipe moving position 421 and the second pipe moving position 422 are respectively located on the first second pipe placement slot 41 and the second second pipe placement slot 41 on the last side of the movable pipe arrangement structure 4, so that: when laying pipes, the first driving device 5 can drive the movable pipe arrangement structure 4 to move the pipe located on the initial pipe placement position 321 to the first pipe placement position 322 through the first pipe moving position 421, and at the same time move the pipe located on the first pipe placement position 322 to the second pipe placement position 323 through the second pipe moving position 422.

[0024] Specifically, the number of first pipe placement slots 31 on the fixed pipe arrangement structure 3 is the same as the number of second pipe placement slots 41 on the movable pipe arrangement structure 4. In this embodiment, the fixed pipe arrangement structure 3 is provided with eight first pipe placement slots 31, and the movable pipe arrangement structure 4 is provided with eight second pipe placement slots 41. Correspondingly, the feeding rack 1 is also provided with a third pipe placement position, a fourth pipe placement position, a fifth pipe placement position, a sixth pipe placement position, a seventh pipe placement position, and an eighth pipe placement position, which are respectively located on the third to eighth first pipe placement slots 31 closest to the first material blocking part 11; the movable pipe arrangement structure 4 is also provided with a third pipe moving position, a fourth pipe moving position, a fifth pipe moving position, a sixth pipe moving position, a seventh pipe moving position, and an eighth pipe moving position, which are respectively located on the third to eighth second pipe placement slots 41 on the rear side of the movable pipe arrangement structure 4.

[0025] During pipe laying, eight identical pipe-moving actions of the movable pipe laying structure 4 are required to sequentially place eight pipes onto the eight first pipe placement slots 31 of the fixed pipe laying structure 3. In the first pipe-moving action, the first driving device 5 drives the movable pipe laying structure 4 to move, so that the first pipe-moving position 421 is directly below the pipe at the initial placement position 321. Then, the first driving device 5 drives the movable pipe laying structure 4 to move upward, so that the first pipe-moving position 421 lifts the pipe at the initial placement position 321 and makes it higher than the first stop part 11. Finally, the first driving device 5 drives the movable pipe laying structure 4 to move forward and downward sequentially, placing the pipe at the first pipe-moving position 421 onto the first placement position 322. In the second pipe-moving action, the first driving device 5 drives the movable pipe laying structure 4 to move, so that the first pipe-moving position 421 and the second pipe-moving position 322 are positioned at the first placement position 322. 2. The pipes are located directly below the initial pipe placement position 321 and the first pipe placement position 322 respectively. Finally, the first driving device 5 drives the moving pipe arrangement structure 4 to move upward, so that the first pipe placement position 421 and the second pipe placement position 422 respectively lift the pipes on the initial pipe placement position 321 and the first pipe placement position 322 and make them higher than the first baffle part 11. Finally, the first driving device 5 drives the moving pipe arrangement structure 4 to move forward and downward in sequence, placing the pipes on the first pipe placement position 421 and the second pipe placement position 422 on the first pipe placement position 322 and the second pipe placement position 323 respectively; ... and so on, until the pipes are placed on all eight first pipe placement slots 31 of the fixed pipe arrangement structure 3.

[0026] In this embodiment, as long as the feeding rack 1 has at least an initial tube placement position 321, a first tube placement position 322, and a second tube placement position 323, and the movable tube arrangement structure 4 has at least a first tube transfer position 421 and a second tube transfer position 422, regardless of how many first tube placement slots 31 are on the fixed tube arrangement structure 3, the movable tube arrangement structure 4 can arrange the tubes sequentially on the fixed tube arrangement structure 3. This makes the feeding device suitable for pressure measuring devices 10 with different numbers of pressure measuring stations, which helps to expand the applicability of the feeding device. Moreover, during tube arrangement, the forward and backward movement of the movable tube arrangement structure 4 is small, making the feeding device compact, small in size, and occupying less space, which is beneficial for the assembly and transportation of the feeding device.

[0027] In some specific embodiments, reference is made to Figure 2 A limiting rod 45 protrudes from the front side of the movable pipe structure 4, and the limiting rod 45 is spaced apart from the bottom of the movable pipe structure 4.

[0028] Specifically, the front end of the movable pipe arrangement structure 4 is provided with a pushing surface 46, and a limiting rod 45 protrudes from the pushing surface 46. The pushing surface 46 allows the movable pipe arrangement structure 4 to simultaneously feed the pre-sorted next batch of pipes to be tested onto the pressure testing device 10, and push the previous batch of pipes already tested onto the unloading device 20. This improves the flow rate of the pipes on the pipe pressure testing machine and increases production efficiency. While the movable pipe arrangement structure 4 pushes the pipes, the limiting rod 45 is located above the already tested pipes. The distance between the limiting rod 45 and the supporting structure of the pressure testing device 10 is only large enough for one pipe. Therefore, the limiting rod 45 prevents pipes from stacking during pushing, thus avoiding disordered pipe order and errors in the screening of good and bad products.

[0029] In some specific embodiments, reference is made to Figure 2 The movable pipe structure 4 has a cavity 43 inside, and a limit drive device 44 is provided in the cavity 43. The limit drive device 44 is connected to the limit rod 45 to drive the limit rod 45 to move back and forth.

[0030] Specifically, the limiting drive device 44 includes a limiting drive cylinder, and a limiting rod 45 is mounted on the piston rod of the limiting drive cylinder. During pipe laying, the piston rod of the limiting drive cylinder and the limiting rod 45 are in a retracted state to prevent the pipes on the pressure measuring device 10 from being affected by the vertical and horizontal movement of the moving pipe laying structure 4; during loading, the piston rod of the limiting drive cylinder and the limiting rod 45 are in an extended state to prevent the pipes from being stacked. This configuration makes the loading device more compatible with the pressure measuring device 10, and makes it easier for technicians to install and assemble.

[0031] In some specific embodiments, reference is made to Figure 1 and Figure 3 The first driving device 5 includes a movable frame 51 and a front and rear drive motor 52 and an up and down drive cylinder 53 mounted on the movable frame 51. The movable pipe arrangement structure 4 is mounted on the movable frame 51. The rear side of the movable frame 51 is provided with a material-lifting drive device 61 and a material-lifting component 62 connected by transmission. The feeding section 2 includes a second feeding ramp 22. The second feeding ramp 22, the first feeding ramp 21 and the fixed pipe arrangement structure 3 are arranged in sequence. A second baffle 14 is provided between the second feeding ramp 22 and the first feeding ramp 21. The first driving device 5 can adjust the front and rear positions of the material-lifting drive device 61 and the material-lifting component 62 so that the material-lifting component 62 lifts the pipe closest to the second baffle 14 on the second feeding ramp 22 and transports it to the first feeding ramp 21.

[0032] In this embodiment, multiple pipes can be placed on the second feeding ramp 22 at once during loading. The first driving device 5 can adjust the front and rear position of the top material member 62, thereby adjusting the front and rear relative positions of the top material member 62 and the second baffle part 14, so that when the top material member 62 is loading, it only lifts the pipe closest to the second baffle part 14 on the second feeding ramp 22, which greatly increases the probability that only one pipe will be delivered to the first feeding ramp 21 at a time. Similarly, the first driving device 5 can also adjust the front and rear position of the movable pipe arrangement structure 4, thereby adjusting the front and rear relative position of the rear side of the movable pipe arrangement structure 4 and the first baffle part 11, so that the first pipe moving position 421 of the movable pipe arrangement structure 4 can only lift the pipe closest to the first baffle part 11 on the first feeding ramp 21 at a time. If the top material component 62 accidentally feeds two or more pipes onto the first feeding ramp 21 at once, the moving pipe arrangement structure 4 can correct this error, ensuring that each pipe movement by the moving pipe arrangement structure 4 removes only one pipe from the first feeding ramp 21. This design improves the orderliness of pipe feeding and more efficiently arranges the pipes sequentially on the fixed pipe arrangement structure 3.

[0033] The front and rear positions of the top material component 62 and the movable pipe arrangement structure 4 are relatively fixed. Furthermore, the front and rear distance between the top material component 62 and the movable pipe arrangement structure 4 is matched with the length of the first feeding ramp 21 in the front and rear direction. This ensures that when the first pipe moving position 421 is directly below the pipe at the initial pipe position 321, the top material component 62 is directly below the pipe closest to the second stop part 14 on the second feeding ramp 22. This allows the first pipe moving position 421 and the top material component 62 to simultaneously lift the corresponding pipe, which is beneficial to further improve the feeding efficiency.

[0034] In some specific embodiments, reference is made to Figure 1 and Figure 3 The movable frame 51 includes a movable plate 511 and a movable frame 512. The movable plate 511 is slidably connected to the loading rack 1 via a locking block 5111 and a guide rail 5112. The front and rear drive motors 52 and the up and down drive cylinders 53 are mounted on the movable plate 511. The movable pipe structure 4 is mounted on the movable frame 512. A gear 521 is mounted on the shaft of the front and rear drive motors 52, and a rack 522 is mounted on the loading rack 1. The gear 521 and the rack 522 are meshed together. The guide rail 5112 and the rack 522 are both along the front and rear... Extending in the direction, both ends of the movable plate 511 are provided with upwardly extending connecting plates 513. The connecting plates 513 are provided with rollers 5131. The two sides of the movable frame 512 are provided with side frames 5121. The two side frames 5121 correspond one-to-one with the two connecting plates 513. The side frames 5121 are provided with vertically extending sliding grooves 5122. The rollers 5131 are locked in the sliding grooves 5122. The movable end 2322 of the vertical drive electric cylinder 53 is connected to the movable frame 512 to drive the movable frame 512 to move up and down.

[0035] In this embodiment, the movable pipe structure 4 and the top material component 62, which need to move in the vertical and horizontal directions, are structurally integrated by the movable frame 51. The forward and backward movement and the vertical movement are carried out by the front and rear drive motors 52 and the up and down drive cylinders 53, respectively. This makes the structure of the feeding device more compact, further reduces the space occupied by the feeding device, and also helps to reduce the use of motors, cylinders and other drives, which helps to reduce manufacturing costs.

[0036] In some specific embodiments, reference is made to Figure 1 , Figure 3 and Figure 4 The feeding device also includes two pipe storage racks 7 located on both sides of the feeding rack 1. The pipe storage rack 7 is provided with a support surface 71 for supporting the pipe material. A pipe baffle 12 is provided on the rear side of the feeding rack 1. The pipe baffle 12 is used to restrict the pipe material on the pipe storage rack 7 from moving backward. The feeding part 2 includes a swing feeding device 23. The swing feeding device 23 includes a swing drive device 231 and a swing frame 232 connected by transmission. The swing frame 232 is connected to the second feeding ramp 22. The front end and rear end of the swing frame 232 are respectively provided with a hinge end 2321 and a movable end 2322. The hinge end 2321 is located on the upper side of the support surface 71 and is rotatably connected to the feeding rack 1. The swing drive device 231 can drive the movable end 2322 to swing from the lower side of the support surface 71 to the upper side of the hinge end 2321 to transport the pipe material to the second feeding ramp 22.

[0037] Specifically, a support frame 13 is provided on the front side of the pipe baffle 12. During the swinging motion of the swing frame 232, from below the support surface 71 to being flush with the hinged end 2321, the movable end 2322 remains inside the support frame 13, preventing the pipe from falling between the swing frame 232 and the pipe baffle 12. During loading, technicians place multiple pipes on the storage rack 7, and the swing feeding device 23 transports the pipes to the second feeding ramp 22, further improving the automation of the loading device, reducing the workload of technicians, and increasing loading efficiency.

[0038] This embodiment also discloses a pipe pressure testing machine, see reference. Figure 5 This includes the feeding device for the aforementioned pipe pressure testing machine.

[0039] In some specific embodiments, reference is made to Figure 5 The pipe pressure testing machine also includes a pressure testing device 10 and a feeding device 20. The feeding device, pressure testing device 10 and feeding device 20 are arranged from back to front. The front end of the movable pipe arrangement structure 4 is provided with a pushing surface 46, so that when the movable pipe arrangement structure 4 feeds the pipe to the pressure testing device 10, the pushing surface 46 pushes the pipe that has completed the pressure test on the pressure testing device 10 to the feeding device 20.

[0040] In this embodiment, the distance between adjacent first pipe placement slots 31 on the fixed pipe arrangement structure 3, the distance between adjacent second pipe placement slots 41 on the movable pipe arrangement structure 4, and the distance between adjacent pressure testing stations on the pressure testing device 10 are the same, so that the pipes fed by the movable pipe arrangement structure 4 can be quickly aligned with the corresponding pressure testing stations to complete the feeding.

[0041] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. 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.
