Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0028] Please refer to Figures 1-5 The utility model discloses a water conservancy pipeline bending device for building construction, which comprises a fixed base 1, and the fixed base 1 is provided with a clamping mechanism 2 and a bending mechanism 3.
[0029] The clamping mechanism 2 comprises a rotating assembly, a reset assembly and a clamping assembly. The rotating assembly comprises a fixed shell 21 fixedly connected to the top surface of the fixed base 1. The inner wall of the fixed shell 21 is rotatably connected with a rotating drum 22. The outer wall of the rotating drum 22 is provided with a plurality of sawtooth grooves 23. The inner wall of the fixed shell 21 is fixedly connected with a first motor 24. The output end of the first motor 24 is fixedly connected with a first rotating shaft 25 through a shaft coupling. The left end of the first rotating shaft 25 extends to the inner wall of the fixed shell 21. The left end of the first rotating shaft 25 is fixedly connected with a gear 26.
[0030] Among them, as Figure 2 , Figure 3 and Figure 5As shown, the reset assembly includes a first electric push rod 27 fixedly connected to the inner wall of the rotating drum 22. A push cylinder 28 is fixedly connected to the output end of the first electric push rod 27. A gear 26 meshes with a serrated groove 23 located on the lower side. Several spring grooves 29 are provided on the left side of the rotating drum 22. Limiting blocks 210 are slidably connected to the inner walls of each of the spring grooves 29. Guide rods 212 are fixedly connected to the sides of the limiting blocks 210 that are close to each other. The ends of the guide rods 212 that are close to each other are connected to the spring grooves. The inner wall of the spring groove 29 is fixedly connected, and the inner wall of the spring groove 29 is fixedly connected with a guide rod 212. The outer wall of the guide rod 212 is slidably connected to the inner wall of the limiting block 210. The clamping assembly includes clamping blocks 213 fixedly connected to the left side of the limiting blocks 210. The ends of the clamping blocks 213 extend to the inner wall of the rotating cylinder 22. The outer wall of the clamping blocks 213 is fixedly connected with a slope block 214. The outer wall of the slope block 214 is slidably connected to the inner wall of the push cylinder 28.
[0031] By setting up the clamping mechanism 2, the pipe is clamped and fixed by driving several clamping blocks 213 to move closer together using the first electric push rod 27. After the push cylinder 28 is reset, several springs 211 push the clamping blocks 213 to move away from each other and release the pipe. In conjunction with the first motor 24 driving the rotating cylinder 22 to rotate and adjust, the clamped pipe can be automatically rotated and adjusted, which is convenient for the subsequent bending mechanism 3 to bend the pipe at a specific angle and direction without the need for manual adjustment of the clamping direction. Compared with manual operation, it is time-saving, labor-saving and has a smaller error rate. It can also be used to bend relatively large pipes, which improves the practicality of the device.
[0032] Among them, such as Figure 2 , Figure 3 and Figure 4 As shown, the bending mechanism 3 includes a drive assembly, a bending assembly, and a limiting assembly. The drive assembly includes a second motor 31 fixedly connected to the inner wall of the fixed base 1. The output end of the second motor 31 is fixedly connected to a second rotating shaft 32 via a coupling. The top end of the second rotating shaft 32 extends to the top surface of the fixed base 1. A rotating plate 33 is fixedly connected to the outer wall of the second rotating shaft 32. A second electric push rod 34 is fixedly connected to the top surface of the rotating plate 33. A top block 35 is fixedly connected to the output end of the second electric push rod 34. The bending assembly includes a serrated cylinder 36 fixedly connected to the top surface of the rotating plate 33. A rotating wheel 37 is slidably connected to the outer wall of the serrated cylinder 36. The bottom surface of the rotating plate 33 is rotatably connected to the top surface of the fixed base 1. The limiting assembly includes a threaded rod 38 threadedly connected to the inner wall of the serrated cylinder 36. A limiting plate 39 is fixedly connected to the top surface of the threaded rod 38.
[0033] By setting the bending mechanism 3, the cooperation of the second electric push rod 34 and the second motor 31 is used to drive the outer wall of the pipeline clamped and fixed by the clamping mechanism 2 to slide with the inner wall of the runner 37 and the top block 35, and the pipeline is limited and bent by turning over the top block 35 through the rotating plate 33, which to some extent reduces the deviation that may occur during the bending of the pipeline, so that the personnel safety hazard caused by the ejection of the pipeline from the device is avoided, and the practicability of the device is further improved.
[0034] One specific application of the embodiment is that by setting the clamping mechanism 2, the worker can place the pipeline on one side of the plurality of clamping blocks 213 close to each other, and extend one end of the pipeline into the inner wall of the rotating drum 22. At this time, the first electric push rod 27 is driven to drive the push drum 28 to move horizontally to the left in the rotating drum 22, and the inner wall of the push drum 28 contacts the outer wall of the plurality of inclined blocks 214, so that the plurality of inclined blocks 214 are driven to approach each other along the inclined surface under the action of the push drum 28, and the plurality of clamping blocks 213 are driven to approach each other, clamping and fixing the pipeline. At this time, the plurality of clamping blocks 213 approach each other, driving the plurality of limiting blocks 210 on them to slide in the spring groove 29 and compress the spring 211. The plurality of guide rods 212 set in the spring groove 29 limit the sliding of the plurality of limiting blocks 210 in the spring groove 29. When the pipeline needs to be released, the first electric push rod 27 is driven to drive the push drum 28 to reset, so that the plurality of clamping blocks 213 are driven to move away from each other under the elastic force of the plurality of springs 211 through the limiting blocks 210, and the pipeline is released. When the pipeline is clamped in the plurality of clamping blocks 213, the first motor 24 is driven to rotate the gear 26 in the fixed housing 21 through the first rotating shaft 25. Since the gear 26 is engaged with the sawtooth groove 23, the rotation of the gear 26 drives the rotating drum 22 to rotate in the fixed housing 21 through the plurality of sawtooth grooves 23, and the pipeline clamped thereon needs to be bent towards the runner 37 in the bending mechanism 3. At this time, the bending mechanism 3 is used to limit and bend the bent end of the pipeline, which realizes the use of the first electric push rod 27 to drive the plurality of clamping blocks 213 to approach each other to clamp and fix the pipeline, and the plurality of springs 211 to push the plurality of clamping blocks 213 to move away from each other to release the pipeline after the push drum 28 is reset. The first motor 24 drives the rotating drum 22 to rotate and adjust, so that the clamped pipeline can be automatically rotated and adjusted, which is convenient for the subsequent bending mechanism 3 to bend the pipeline at a specific angle, and manual adjustment is not needed. Compared with manual operation, it is time-saving and labor-saving, has less mistakes, and can be used for bending relatively large pipelines, which improves the practicability of the device.
[0035] By setting the bending mechanism 3, the clamping mechanism 2 is matched to complete the clamping and fixing of the pipeline and the rotation adjustment, the second electric push rod 34 is driven to drive the top block 35 to slide backward, the pipeline left end is limited between the top block 35 and the rotating wheel 37, the second motor 31 is driven to drive the rotating plate 33 to rotate through the second rotating shaft 32, the rotating plate 33 drives the rotating wheel 37 on the limiting sawn tooth cylinder 36 to rotate around the second rotating shaft 32 through the sawn tooth cylinder 36, so that the pipeline limited between the rotating wheel 37 and the top block 35 is clamped and fixed by the clamping mechanism 2, the pipeline left end extends along the inner wall of the rotating wheel 37 and the top block 35 to be bent around the second rotating shaft 32, at this time, the second electric push rod 34 continuously drives the top block 35 to resist the internal stress of the bent pipeline, wherein the outer wall of the pipeline left end is in a sliding state between the rotating wheel 37 and the top block 35 during the pipeline bending, personnel can also take out the threaded rod 38 from the sawn tooth cylinder 36 by grabbing the limiting disc 39 to drive the threaded rod 38 to rotate along the internal thread of the sawn tooth cylinder 36, the limiting of the limiting disc 39 to the rotating wheel 37 is released, the rotating wheel 37 is conveniently taken off from the sawn tooth cylinder 36 to replace the limiting hole diameter of the rotating wheel 37 to the pipeline, wherein the top block 35 and the output end of the second electric push rod 34 are bolted and connected, the cylinder rotating wheel 37 can also replace the relevant pipeline hole diameter, the second electric push rod 34 and the second motor 31 are driven in cooperation to slide the outer wall of the pipeline clamped and fixed by the clamping mechanism 2 along the inner wall of the rotating wheel 37 and the top block 35, the pipeline is limited and bent by the rotating plate 33 overturning the top block 35, to a certain extent, the deviation of the pipeline during the bending process is reduced, the situation that the pipeline pops out of the device to endanger the safety of personnel is avoided, and the practicability of the device is further improved.
