Description

Technical Field

[0001] The utility model relates to the technical field of sand lifting devices, and more specifically, it relates to a sand lifting device for the production of grooved pipe fittings. Background Art

[0002] In the existing technology, the existing device cannot quickly release the clamping of the pipeline used for sand lifting. During the sand lifting process, the clamping and releasing of the pipeline are common operations, especially when the pipeline needs to be replaced or cleaned. However, this point has not been fully considered in the design of the existing device, resulting in the process of pipeline clamping and releasing may be more cumbersome and time-consuming, affecting production efficiency and equipment maintenance efficiency.

[0003] Secondly, the existing device lacks the clamping and fixing process for sand lifting. Clamping and fixing are important steps to ensure the stable connection of the sand lifting pipeline, which can prevent the pipeline from falling off or leaking during the transportation process. However, the insufficient design of the existing device in clamping and fixing may lead to unstable connection of the sand lifting pipeline, affecting the smooth progress of the sand lifting process.

[0004] Finally, the existing device lacks the process of recycling sand. During the production process of grooved pipe fittings, sand is a valuable resource, and its recycling can reduce production costs and resource waste. However, this point has not been fully considered in the design of the existing device, resulting in possible waste of sand during the transportation and use process, affecting the economy and environmental protection of production.

[0030] Please refer to Figures 1-5, A sand lifting device for the production of grooved pipe fittings, including a circulation cylinder 1. An unlocking component is provided on the circulation cylinder 1. The unlocking component includes an insertion pipe 2, a fixed pipe 3, a sliding sleeve 4, an unlocking block 5, a clamping groove 6 and an insertion block 7. The insertion pipe 2 is arranged at the top of the circulation cylinder 1. The fixed pipe 3 is slidably connected to the outside of the insertion pipe 2. The sliding sleeve 4 is slidably connected to the outside of the fixed pipe 3. The unlocking blocks 5 are evenly arranged on one side of the sliding sleeve 4. The clamping groove 6 is opened on the insertion pipe 2. The insertion block 7 is slidably connected to the fixed pipe 3. The insertion block 7 is adapted to the clamping groove 6. A sealing component is arranged between the fixed pipe 3 and the insertion pipe 2. The sealing component includes a pressing block 8, an insertion groove 9 and a corrugated pipe 10. The pressing block 8 is connected to the insertion pipe 2. The insertion groove 9 is opened on the fixed pipe 3. The pressing block 8 is adapted to the insertion groove 9.

[0031] A sliding block 11 is connected to the bottom of the insertion block 7. The sliding block 11 is slidably connected to the unlocking block 5. There are four insertion blocks 7.

[0032] Pulling springs 12 are connected between both ends of the insertion block 7 and the fixed pipe 3.

[0033] A threaded pipe 13 is threadedly connected to the outside of the fixed pipe 3.

[0034] A sliding piece 14 is slidably connected to the fixed pipe 3.

[0035] In this embodiment, when it is necessary to release the clamping between the insertion tube 2 and the fixing tube 3, the sliding sleeve 4 is manually slid along the fixing tube 3, so that the unlocking block 5 at one end of the sliding sleeve 4 abuts against the sliding block 11. During the sliding movement, the sliding block 11 is pushed out. When the sliding block 11 moves, the insertion block 7 is taken out from the clamping groove 6 of the insertion tube 2. During the pushing process of the sliding sleeve 4, the tension springs 12 at both ends of the insertion block 7 are stretched. When the fixing tube 3 and the insertion tube 2 are fixedly clamped, the fixing tube 3 is manually slid and inserted along the insertion tube 2. When the insertion groove 9 of the fixing tube 3 abuts against the abutting block 8 of the insertion tube 2, the sliding sleeve 4 is manually slid in the reverse direction to restore it to the initial position, so as to drive the unlocking block 5 to move and release the restriction on the sliding block 11, release the stretching process of the tension springs 12, and under the action of the elastic potential energy of the tension springs 12, the insertion block 7 is restored to the initial position and inserted into the insertion tube 2, thus completing the clamping and fixing process between the insertion tube 2 and the fixing tube 3. And by manually rotating the threaded tube 13, the threaded tube 13 rotates along the fixing tube 3 in a threaded manner, so as to drive the sliding piece 14 to slide along the fixing tube 3, so that the sliding piece 14 moves to abut against one end of the insertion block 7, so that the insertion block 7 will not be driven to move due to mistakes during use.

[0036] Please refer to Figures 4-5 , as an implementation mode of a sand lifting device for the production of grooved pipe fittings of a circulating component: The circulating component includes a circulating pipe 15, an installation cylinder 16 and a climbing ladder 17. The circulating pipe 15 is connected to the bottom of the circulating cylinder 1, the installation cylinder 16 is connected to the bottom of the circulating pipe 15, and the climbing ladder 17 is arranged on one side of the installation cylinder 16.

[0037] A material leakage plate 18 is installed inside the installation cylinder 16, a material leakage hopper 19 is installed at the bottom of the material leakage plate 18, a conveying cylinder 20 is installed at the bottom of the installation cylinder 16, a screw rod 21 is rotatably connected inside the conveying cylinder 20, a screw blade 22 is sleeved outside the screw rod 21, a discharge port 23 is opened on one side of the conveying cylinder 20, a collection bin 24 is arranged on one side of the installation cylinder 16, the discharge port 23 connects the collection bin 24 and the conveying cylinder 20, one end of the screw rod 21 is rotatably connected to the collection bin 24, and a conveying motor 25 is installed at the top side end of the collection bin 24.

[0038] The output end of the conveying motor 25 is connected with a driving gear 26. A transmission rod 27 is rotatably connected inside the collection bin 24. One end of the transmission rod 27 is rotatably connected with a driven gear 28. A transmission chain 29 is provided for driving connection between the driven gear 28 and the driving gear 26. A conveying sprocket 30 is installed on the screw rod 21 and the transmission rod 27 inside the collection bin 24. A conveying chain 31 is drivingly connected to the conveying sprocket 30. A tipping bucket 32 is installed on the conveying chain 31, and multiple tipping buckets 32 are provided.

[0039] More specifically, during use, the material is manually put into the installation cylinder 16. During the process of processing the trench pipe fittings in the installation cylinder 16, after the sand is used, it leaks out along the leakage plate 18 and finally leaks out along the leakage hopper 19, so that it leaks into the conveying cylinder 20. The conveying motor 25 is manually started to drive the driving gear 26 to rotate. Then, under the action of the transmission chain 29, the driven gear 28 is driven to rotate, and then the transmission rod 27 is driven to rotate, thereby driving the conveying sprocket 30 to rotate. Then, under the drive of the conveying chain 31, the screw rod 21 is driven to rotate. Thus, under the action of the spiral blade 22, the sand drives the material to be sent into the collection bin 24 along the discharge port 23. And under the action of the conveying chain 31 of the conveying sprocket 30, the sand in the collection bin 24 is sent to the top of the collection bin 24 and finally sent into the fixed pipe 3 along the corrugated pipe 10, and finally injected into the circulation cylinder 1 along the insertion pipe 2, thus completing the circulation process of the sand. Moreover, after the sand is used for a period of time and needs to be replaced, the fixing of the fixed pipe 3 and the insertion pipe 2 is released, so that the fixed pipe 3 is introduced to the other end, and the sand is taken out, thus completing the replacement process of the sand.

[0040] In summary, when the overall device is in use or operation: when it is necessary to release the clamping between the insertion tube 2 and the fixed tube 3, the sliding sleeve 4 is manually slid along the fixed tube 3, so that the unlocking block 5 at one end of the sliding sleeve 4 abuts against the sliding block 11. During the sliding movement, the sliding block 11 is pushed out. When the sliding block 11 moves, the insertion block 7 is driven to be taken out from the clamping groove 6 of the insertion tube 2. During the pushing process of the sliding sleeve 4, the tension springs 12 at both ends of the insertion block 7 are stretched. When the fixed tube 3 and the insertion tube 2 are fixedly clamped, the fixed tube 3 is manually slid and inserted along the insertion tube 2. When the insertion groove 9 of the fixed tube 3 abuts against the abutting block 8 of the insertion tube 2, the sliding sleeve 4 is manually slid in the reverse direction to return it to the initial position, so that the unlocking block 5 is driven to move, releasing the restriction on the sliding block 11, releasing the stretching of the tension spring 12. Under the action of the elastic potential energy of the tension spring 12, the insertion block 7 is restored to the initial position and inserted into the insertion tube 2, thus completing the clamping and fixing process between the insertion tube 2 and the fixed tube 3. And by manually rotating the threaded tube 13, the threaded tube 13 rotates along the fixed tube 3 in a threaded manner, so that the sliding piece 14 is driven to slide along the fixed tube 3, driving the sliding piece 14 to move to abut against one end of the insertion block 7, so that the insertion block 7 will not be driven to move due to mistakes during use.

[0041] During use, the material is manually placed into the installation cylinder 16, and the grooved pipe fittings are processed in the installation cylinder 16. After the sand is used, it leaks out along the leakage plate 18 and finally leaks out along the leakage hopper 19, falling into the conveying cylinder 20. By manually turning on the conveying motor 25, it drives the driving gear 26 to rotate. Then, under the action of the transmission chain 29, the driven gear 28 is driven to rotate, driving the transmission rod 27 to rotate, thereby driving the conveying sprocket 30 to rotate. Then, under the drive of the conveying chain 31, the screw rod 21 is driven to rotate. Under the action of the spiral blade 22, the sand is driven to send the material along the discharge port 23 into the collection bin 24. And under the action of the conveying chain 31 of the conveying sprocket 30, the sand in the collection bin 24 is sent to the top of the collection bin 24 and finally sent to the fixed tube 3 along the corrugated pipe 10, and finally injected into the circulation cylinder 1 along the insertion tube 2, thus completing the circulation process of the sand. Moreover, after the sand is used for a period of time and needs to be replaced, the fixed tube 3 and the insertion tube 2 are released from fixation, so that the fixed tube 3 is introduced to the other end to take out the sand, thus completing the sand replacement process.

[0042] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded.
