Description

Technical Field

[0001] This utility model belongs to the field of pipe joint testing technology, and in particular relates to a tooling for testing the water pressure of boiler pipe joints. Background Technology

[0002] According to the published patent CN220829407U, a boiler pipe joint water pressure testing fixture includes a hollow testing base and a boiler pipe joint body. A clamping assembly is connected to the interior and upper surface of the hollow testing base. A limiting seat is fixedly provided on the upper surface of the hollow testing base, and the boiler pipe joint body can be placed inside the limiting seat. A limiting sealing assembly is connected to the limiting seat. The clamping assembly includes a first rotating rod, which is rotatably connected to the interior of the hollow testing base. A gear is sleeved on the outer surface of the first rotating rod. After the above equipment is completed, the clamping assembly, in conjunction with the limiting sealing assembly, can improve the convenience of water pressure testing of the boiler pipe joint. The clamping assembly can clamp and fix the boiler pipe joint body, improving the stability of water pressure testing of the boiler pipe joint body. However, the following shortcomings still exist:

[0003] After the above equipment is completed, it only clamps and fixes the pipe joint. However, it is difficult to recycle the water in the pipe joint after the pipe joint test is completed, which wastes the water and increases the test cost. Therefore, we propose a boiler pipe joint water pressure test fixture. Utility Model Content

[0004] The purpose of this utility model is to provide a boiler pipe joint water pressure testing fixture, which solves the problem through a filtering mechanism and a clamping mechanism.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a boiler pipe joint water pressure testing fixture, including a water tank, a working plate fixedly connected to the inner wall of the water tank, a plurality of circular grooves opened on the inner wall of the working plate, a placement plate fixedly connected to the top outer wall of the working plate, a filter mechanism provided on the outer wall of the water tank, and a clamping mechanism provided on the inner wall of the working plate.

[0007] The filtration mechanism includes a controller. A first motor is fixedly connected to the outer wall of the water tank. A rotating shaft is fixedly connected to the bottom output end of the first motor via a coupling. Several cams are fixedly connected to the outer wall of the rotating shaft. Several fixed plates are fixedly connected to the inner wall of the water tank. A circular hole is opened in the inner wall of the fixed plate. A sliding rod is slidably connected to the inner wall of the circular hole. A spring is sleeved on the outer wall of the sliding rod. A filter plate is fixedly connected to the outer wall of the sliding rod near the placement plate. Several protrusions are fixedly connected to the bottom outer wall of the filter plate. A water pipe is fixedly connected to the inner wall of the water tank. A high-pressure pump is fixedly connected to the outer wall of the water pipe. A corrugated pipe is fixedly connected to the output end of the high-pressure pump.

[0008] Furthermore, the outer wall of the controller is fixedly connected to the outer wall of the water tank, the outer wall of the rotating shaft is rotatably connected to the inner wall of the water tank, and the outer wall of the high-pressure pump is fixedly connected to the outer wall of the water tank.

[0009] Furthermore, the clamping mechanism includes a second motor, the outer wall of which is fixedly connected to the inner wall of the work plate, and a roller is fixedly connected to the bottom output end of the second motor via a coupling.

[0010] Furthermore, a gear is fixedly connected to the outer wall of the roller, and several threaded rods are rotatably connected to the inner wall of the working plate. A second gear is fixedly connected to the outer wall of the threaded rod near the gear, and the outer wall of the second gear meshes with the outer wall of the gear.

[0011] Furthermore, the outer wall of the threaded rod is threadedly connected to a threaded block, and the outer wall of the threaded block is fixedly connected to several joint shafts.

[0012] Furthermore, a connecting rod is rotatably connected to the outer wall of the joint shaft, and a second joint shaft is rotatably connected to the inner wall of the end of the connecting rod away from the joint shaft. A support block is fixedly connected to the outer wall of the second joint shaft, and a circular groove is formed on the inner wall of the support block.

[0013] Furthermore, a number of mounting plates are fixedly connected to the top outer wall of the working plate, and a number of guide rods are fixedly connected to the inner wall of the mounting plates. The outer wall of the guide rods is slidably connected to the inner wall of the circular groove.

[0014] Furthermore, a sleeve is fixedly connected to the outer wall of the support block near the roller, and the inner wall of the sleeve on the left side is fixedly connected to the outer wall of the corrugated pipe. A rubber ring is fixedly connected to the inner wall of the sleeve, and a pipe joint is slidably connected to the inner wall of the rubber ring.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a filter plate and a spring. When the protrusion moves, it carries the filter plate along with it, and the filter plate carries the sliding rod. As the sliding rod moves, it compresses the spring. When the cam is no longer in contact with the protrusion, the spring compresses the sliding rod, causing it to reset. The filter plate then resets along with the sliding rod, allowing it to move up and down. This improves resource utilization, effectively filters used water, prevents impurities from entering the water, facilitates secondary water recycling, and prevents impurities from damaging the high-pressure pump.

[0017] 2. This utility model, by setting up a rubber ring and a sleeve, allows the joint shaft to move along with the threaded block. The joint shaft then moves the connecting rod in an arc shape. As the connecting rod moves, it moves the second joint shaft. The second joint shaft then slides the support block on the guide rod. Simultaneously, the support block moves the sleeve, and the sleeve moves along with the rubber ring. This improves test stability and effectively seals both ends of the pipe joint, preventing water leakage during testing and making the testing process more stable and efficient.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-8 As shown, this utility model is a boiler pipe joint water pressure testing fixture, including a water tank 1. A working plate 101 is fixedly connected to the inner wall of the water tank 1. Several circular grooves 102 are opened on the inner wall of the working plate 101 to store water, so that the operator can use the water to test the pipe joint 316. A placement plate 103 is fixedly connected to the top outer wall of the working plate 101. A filter mechanism 2 is provided on the outer wall of the water tank 1. A clamping mechanism 3 is provided on the inner wall of the working plate 101. The placement plate 103 positions the pipe joint 316 so that the pipe joint 316 is kept in a fixed position when placed.

[0032] The filtration mechanism 2 includes a controller 201. A first motor 202 is fixedly connected to the outer wall of the water tank 1. The operator starts the first motor 202 through the controller 201. The bottom output end of the first motor 202 is fixedly connected to a rotating shaft 203 via a coupling. Several cams 204 are fixedly connected to the outer wall of the rotating shaft 203. After the first motor 202 starts, it will rotate the rotating shaft 203, and then the rotating shaft 203 will rotate the cams 204, realizing the kinetic energy transfer process between the parts. Several fixed plates 205 are fixedly connected to the inner wall of the water tank 1. The inner wall of the fixed plate 205 has a circular hole 206. A sliding rod 207 is slidably connected to the inner wall of the circular hole 206. When the sliding rod 207 slides in the circular hole 206, the sliding rod 207 will not swing, keeping the sliding rod 207 moving horizontally. A spring 208 is sleeved on the outer wall of the sliding rod 207. When the spring 208 is squeezed on the sliding rod 207, the spring 208 will not be misaligned, so that the spring 208 can be used normally. A filter plate 209 is fixedly connected to the outer wall of the sliding rod 207 near the placement plate 103. Several protrusions 210 are fixedly connected to the bottom outer wall of the filter plate 209. When the cam 204 rotates, it will squeeze the protrusions 210, causing the protrusions 210 to move. Then, when the protrusions 210 move, they will carry the filter plate 209 to move, completing the kinetic energy transfer process between the parts. A water pipe 211 is fixedly connected to the inner wall of the water tank 1. A high-pressure pump 212 is fixedly connected to the outer wall of the water pipe 211. A bellows 213 is fixedly connected to the output end of the high-pressure pump 212. The operator starts the high-pressure pump 212 using the controller 201.

[0033] The outer wall of the controller 201 is fixedly connected to the outer wall of the water tank 1, the outer wall of the rotating shaft 203 is rotatably connected to the inner wall of the water tank 1, the outer wall of the high-pressure pump 212 is fixedly connected to the outer wall of the water tank 1, and the clamping mechanism 3 includes a second motor 301. The operator starts the second motor 301 using the controller 201. The outer wall of the second motor 301 is fixedly connected to the inner wall of the work plate 101. The bottom output end of the second motor 301 is fixedly connected to a roller 302 via a coupling, and a gear 303 is fixedly connected to the outer wall of the roller 302. After 301 is started, it will rotate the roller 302, and then the roller 302 will rotate the gear 303, completing the kinetic energy transfer between the parts. The inner wall of the working plate 101 is rotatably connected with several threaded rods 304. The outer wall of the threaded rod 304 near the gear 303 is fixedly connected to a second gear 305. The outer wall of the second gear 305 meshes with the outer wall of the gear 303. When the gear 303 rotates, it will rotate the second gear 305, and then the second gear 305 will rotate the threaded rod 304, realizing the kinetic energy transfer between the parts.

[0034] A threaded block 306 is threadedly connected to the outer wall of the threaded rod 304. Several joint shafts 307 are fixedly connected to the outer wall of the threaded block 306. A connecting rod 308 is rotatably connected to the outer wall of the joint shaft 307. When the threaded rod 304 rotates, the threaded block 306 moves, and the movement of the threaded block 306 moves the joint shaft 307. At the same time, the joint shaft 307 moves the connecting rod 308 in an arc motion, realizing the kinetic energy transfer process between the parts. A second joint shaft 309 is rotatably connected to the inner wall of the end of the connecting rod 308 away from the joint shaft 307. A support block 310 is fixedly connected to the outer wall of the second joint shaft 309. A circular groove 311 is opened on the inner wall of the support block 310. When the connecting rod 308 moves, it moves the second joint shaft 309, and the second joint shaft 309 moves the support block 310, realizing the kinetic energy transfer between the parts. Several mounting plates 312 are fixedly connected to the top outer wall of the work plate 101. The inner wall of the mounting plate 312 is fixedly connected with several guide rods 313. The outer wall of the guide rods 313 is slidably connected to the inner wall of the circular groove 311. When the support block 310 moves, it slides on the guide rods 313. The guide rods 313 limit the support block 310 to prevent it from swinging when it moves. The outer wall of the support block 310 near the roller 302 is fixedly connected with a sleeve 314. The inner wall of the sleeve 314 on the left side is fixedly connected to the outer wall of the corrugated pipe 213. The inner wall of the sleeve 314 is fixedly connected with a rubber ring 315. The inner wall of the rubber ring 315 is slidably connected with a pipe joint 316. When the support block 310 moves, it will move the sleeve 314 with it. Then the sleeve 314 will move the rubber ring 315 with it. When the rubber ring 315 moves, it will clamp the pipe joint 316. The rubber ring 315 seals both ends of the pipe joint 316 to prevent leakage during subsequent testing.

[0035] One specific application of this embodiment is:

[0036] When the operator needs to use the equipment, first place the pipe connector 316 on the placement plate 103. After the pipe connector 316 is placed, the operator uses the controller 201 to start the second motor 301. After the second motor 301 starts, it will rotate the roller 302. When the roller 302 rotates, it will rotate the gear 303. Then, when the gear 303 rotates, it will rotate the second gear 305. When the second gear 305 rotates, the threaded rod 304 will rotate with the second gear 305. Then, when the threaded rod 304 rotates, it will cause the threaded block 306 to move. When the threaded block 306 moves, it will cause the joint shaft 307 to move. Then, the joint shaft 307 will cause the connecting rod 308 to move in an arc. When the connecting rod 308 moves, it will cause the second joint shaft to move. 309 moves, and then the joint shaft 309, along with the support block 310, slides on the guide rod 313. Simultaneously, the support block 310 moves the sleeve 314, which in turn moves the rubber ring 315. As the rubber ring 315 moves, it clamps the pipe joint 316, preventing it from shaking during testing. The rubber ring 315 also seals both ends of the pipe joint 316, preventing water leakage during testing. After the pipe joint 316 is clamped, the operator uses the controller 201 to start the high-pressure pump 212. After the high-pressure pump 212 starts, it draws water from the water tank 1 through the water pipe 211. The water is then pumped by the high-pressure pump 212 into the bellows 213, and finally... Water from pipe 213 is delivered to pipe joint 316, and a water pressure test is performed on pipe joint 316 through continuous water supply. After the test is completed, the operator can use controller 201 to start the second motor 301, causing the second motor 301 to reverse. After the second motor 301 reverses, the rubber ring 315 and sleeve 314 will be removed from the surface of pipe joint 316 through the cooperation of multiple parts. After the rubber ring 315 and sleeve 314 are removed, both ends of pipe joint 316 will open, and the water in pipe joint 316 will flow back to water tank 1. At the same time, when both ends of pipe joint 316 are open, the first motor 202 can be started using controller 201. After the first motor 202 is started, The rotating shaft 203 rotates, which in turn rotates the cam 204. As the cam 204 rotates, it presses against the protrusion 210, causing the protrusion 210 to move. This movement of the protrusion 210 then moves the filter plate 209, which in turn moves the sliding rod 207. As the sliding rod 207 moves, it compresses the spring 208. When the cam 204 is no longer in contact with the protrusion 210, the spring 208 compresses the sliding rod 207, causing it to reset. The filter plate 209 then resets along with the sliding rod 207, causing it to move up and down. During this movement, the filter plate 209 filters the used water, preventing impurities from entering. The filtered water then flows to the bottom of the water tank 1.This facilitates the recycling of water resources.
