Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection technology, and in particular to a municipal pipeline inspection device. Background Technology

[0002] Municipal pipelines are an important component of urban infrastructure. They are devices made up of pipes, pipe fittings, and valves used to transport gases, liquids, or fluids containing solid particles. Existing municipal pipelines may encounter bends in their laying patterns. These bends can generate internal stress on the pipelines. If the bends are too large or the design is inadequate, fatigue damage, leaks, or even ruptures may occur during use, leading to serious safety accidents and economic losses. Therefore, it is necessary to test the bending resistance of pipelines.

[0003] Chinese utility model patent CN221686023U discloses a municipal pipeline inspection device, including a base for support, and a pressure-applying component for pipeline inspection, the pressure-applying component being fixedly disposed on the upper surface of the base; and a support component for supporting the pipeline, the support component being fixedly disposed on the upper surface of the base and located directly below the pressure-applying component. The support component includes a bracket, with a support seat fixedly disposed at the upper end of the bracket, and support plates rotatably disposed on both sides of the support seat. Arc-shaped grooves are formed on the upper surfaces of both the support seat and the support plates. The pipeline is placed on the support seat and support plates, and then the pressure-applying component bends the pipeline.

[0004] Regarding the aforementioned technologies, the inventors believe the following drawbacks exist: When using the device, the pipe is placed within the arc-shaped groove of the support base and support plate for support and positioning. However, when bending pipes of different diameters, the positioning and limiting effect of the arc-shaped groove is insufficient, which can easily cause positional displacement of the pipe during bending, thus affecting the accuracy of bending detection. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a municipal pipeline inspection device.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a municipal pipeline inspection device, including a base plate, a column vertically arranged on the base plate, a sliding plate slidably arranged on the base plate, a mounting frame on the top of the column, a fixed shaft vertically arranged on the side of the mounting frame adjacent to the sliding plate, the center line of the fixed shaft coinciding with the surface of the column, two connecting frames rotatably arranged on the fixed shaft, a vertically arranged support plate arranged on the connecting frame, the surface of the support plate adjacent to the sliding plate being tangent to the surface of the column, a pressure plate vertically slidably arranged on the side of the support plate adjacent to the sliding plate, a sliding assembly for driving the pressure plate to slide on the support plate, a sliding seat vertically slidably arranged on the side of the sliding plate adjacent to the column, an adjusting assembly for adjusting the position of the sliding seat arranged on the sliding plate, pressure columns horizontally spaced on the sliding seat, a hydraulic cylinder horizontally arranged on the base plate, the piston rod of the hydraulic cylinder being connected to the side of the sliding plate away from the column.

[0007] By adopting the above technical solution, a sliding plate, mounting bracket, support plate, sliding assembly, and adjusting assembly are set up. The pipe is placed on the base plate, with its middle part in contact with the surface of the column and its two sides in contact with the support plate. Then, the sliding assembly drives the pressure plate to descend, so that the bottom surface of the pressure plate contacts the top of the pipe, which can restrict pipes of different diameters. Subsequently, the position of the sliding seat is adjusted by the adjusting assembly, thereby aligning the pressure column with the center line of the pipe. Then, the hydraulic cylinder pushes the sliding plate to move, which in turn moves the sliding seat and the pressure column to bend the pipe, enabling bending of pipes of different diameters. During the bending process, the support plate rotates around a fixed axis, and the bending angle of the pipe is determined by the rotation angle of the support plate.

[0008] Furthermore, the mounting bracket is provided with a fixing plate, and two fixing blocks are spaced apart at the bottom of the fixing plate. The side of the fixing block adjacent to the column is tangent to the surface of the column.

[0009] By adopting the above technical solution, a fixed plate and a fixed block are set. In the initial state, the surfaces of the two support plates are coplanar, and at the same time, the connecting frame is in contact with the corresponding fixed block.

[0010] Furthermore, a torsion spring is fitted onto the fixed shaft corresponding to the mounting bracket.

[0011] By adopting the above technical solution, a torsion spring is sleeved on the mounting bracket corresponding to the fixed shaft. The torsion spring provides elastic force to the mounting bracket so that the connecting bracket contacts the fixed block, so that after the bending operation is completed, the torsion spring pushes the connecting bracket and the support plate to reset.

[0012] Furthermore, two connecting plates are vertically spaced at one end of the pressure column away from the sliding seat, and a roller is vertically rotatably arranged between the two connecting plates.

[0013] Furthermore, the base plate is provided with several angular scale grooves spaced circumferentially around the center line of the fixed axis.

[0014] By adopting the above technical solution, setting an angle scale groove, and observing the angle scale groove pointed to by the edge of the support plate, the angle of pipe bending can be determined.

[0015] Furthermore, the support plate is provided with a plurality of first scale grooves at vertical intervals, the pressure plate is provided with a first pointer on the side adjacent to the first scale groove, the sliding plate is provided with a plurality of second scale grooves at vertical intervals, and the sliding seat is provided with a second pointer on the side adjacent to the second scale groove.

[0016] By adopting the above technical solution, a first scale groove, a first pointer, a second scale groove, and a second pointer are set. After the pressure plate contacts the top of the pipe, the diameter of the pipe is obtained according to the first scale groove pointed to by the first pointer. Then, when adjusting the height of the sliding seat, the reading of the second scale groove pointed to by the second pointer is half of the reading of the first scale groove pointed to by the first pointer. At this time, the pressure column is aligned with the center line of the pipe.

[0017] Furthermore, the support plate is provided with three sliding grooves, and a sliding block connected to the pressure plate is slidably disposed in the sliding groove.

[0018] Furthermore, the sliding assembly includes a first threaded rod that is vertically rotatably disposed in one of the grooves, and a sliding block in the groove is helically connected to the first threaded rod through a threaded hole. The upper end of the first threaded rod passes through a support plate and is provided with a control handle.

[0019] By adopting the above technical solution, a first threaded rod and a control handle are set. Rotating the control handle drives the first threaded rod to rotate, thereby driving the sliding block connected to it to move, and in turn driving the pressure plate to move.

[0020] Furthermore, an installation groove is provided on the surface of the sliding plate near the column, and the sliding seat is vertically slidably disposed in the installation groove.

[0021] Furthermore, the adjustment assembly includes a second threaded rod that is vertically rotatably disposed in the mounting groove, the sliding seat is helically connected to the second threaded rod through a threaded hole, and the upper end of the second threaded rod passes through the sliding plate and is provided with an adjustment handle.

[0022] By adopting the above technical solution, an adjustment handle and a second threaded rod are set. Rotating the adjustment handle drives the second threaded rod to rotate, thereby causing the sliding seat to slide, and then driving the pressure column to move.

[0023] In summary, this utility model has the following beneficial effects: It includes a sliding plate, mounting bracket, support plate, sliding assembly, and adjusting assembly. The pipe is placed on the base plate, with its center contacting the surface of the column and both sides contacting the support plate. The sliding assembly drives the pressure plate to descend, bringing its bottom surface into contact with the top of the pipe, thus restricting pipes of different diameters. The adjusting assembly then adjusts the position of the sliding seat, aligning the pressure column with the centerline of the pipe. A hydraulic cylinder then moves the sliding plate, causing the sliding seat and pressure column to move and bend the pipe, enabling bending of pipes of different diameters. During the bending process, the support plate rotates around a fixed axis, and the bending angle of the pipe is determined by the angle of rotation of the support plate. Attached Figure Description

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] like Figure 1-4As shown in the illustration, this application discloses a municipal pipeline inspection device, including a base plate 10, a sliding plate 30, a sliding assembly 50, and an adjusting assembly 60. A column 20 is vertically mounted on the base plate 10. The sliding plate 30 is slidably mounted on the base plate 10. A mounting bracket 21 is mounted on the top of the column 20. A fixed shaft 22 is vertically mounted on the side of the mounting bracket 21 adjacent to the sliding plate 30, and the center line of the fixed shaft 22 coincides with the surface of the column 20. Two connecting brackets 23 are rotatably mounted on the fixed shaft 22. A vertically arranged support plate 40 is mounted on the connecting bracket 23, and the surface of the support plate 40 adjacent to the sliding plate 30 is tangent to the surface of the column 20. A pressure plate 41 is vertically slidably mounted on the side of the support plate 40 adjacent to the sliding plate 30. The sliding assembly 50 is mounted on the support plate 40 and is used to drive the pressure plate 41 to slide. The pipe is placed on the base plate 10, with its middle part contacting the surface of the column 20 and its two sides contacting the support plates 40 respectively. The sliding assembly 50 then drives the pressure plate 41 to descend, so that the bottom surface of the pressure plate 41 contacts the top of the pipe, thus restricting pipes of different diameters. A sliding seat 31 is vertically slidably mounted on the side of the sliding plate 30 adjacent to the column 20. An adjustment assembly 60 is mounted on the sliding plate 30 to adjust the position of the sliding seat 31. Pressure columns 32 are horizontally spaced on the sliding seat 31, with two pressure columns 32 corresponding to two support plates 40 respectively. The position of the sliding seat 31 is adjusted by the adjustment assembly 60, thereby aligning the pressure columns 32 with the centerline of the pipe. This allows for bending tests on pipes of different diameters. A hydraulic cylinder 11 is horizontally mounted on the base plate 10. The piston rod of the hydraulic cylinder 11 is connected to the side of the sliding plate 30 away from the column 20. The hydraulic cylinder 11 pushes the sliding plate 30 to move, causing the sliding seat 31 and pressure columns 32 to move and bend the pipe. During the subsequent bending process, the support plate 40 rotates around the fixed axis 22. The bending angle of the pipe is determined based on the rotation angle of the support plate 40. This test assesses the pipe's bending resistance to prevent fatigue damage, leaks, or even ruptures caused by bending during pipe laying, thus avoiding serious safety accidents and economic losses.

[0031] Specifically, the support plate 40 has three grooves 44, and a sliding block 45 connected to the pressure plate 41 is slidably disposed in the groove 44 to ensure the stability of the sliding of the pressure plate 41. The sliding assembly 50 includes a first threaded rod 51 that is vertically rotatably disposed in one of the grooves 44. The sliding block 45 in the groove 44 is helically connected to the first threaded rod 51 through a threaded hole. The upper end of the first threaded rod 51 passes through the support plate 40 and is provided with a control handle 52. Rotating the control handle 52 drives the first threaded rod 51 to rotate, thereby driving the sliding block 45 connected to it to move, and thus driving the pressure plate 41 to move.

[0032] A mounting groove 37 is provided on the surface of the sliding plate 30 near the column 20, and the sliding seat 31 is vertically slidably disposed in the mounting groove 37. The adjusting assembly 60 includes a second threaded rod 61 that is vertically rotatably disposed in the mounting groove 37. The sliding seat 31 is screwed to the second threaded rod 61 through a threaded hole. The upper end of the second threaded rod 61 passes through the sliding plate 30 and is provided with an adjusting handle 62. Rotating the adjusting handle 62 drives the second threaded rod 61 to rotate, thereby driving the sliding seat 31 to slide, and in turn driving the pressure column 32 to move.

[0033] During setup, the base plate 10 has several angle scale grooves 12 spaced circumferentially around the center line of the fixed shaft 22. By observing the angle scale grooves 12 pointed to by the edge of the support plate 40, the bending angle of the pipe can be determined. The support plate 40 has several first scale grooves 42 spaced vertically. A first pointer 43 is provided on the side of the pressure plate 41 near the first scale groove 42. The first scale groove 42 and the first pointer 43 cooperate. The reading of the first scale groove 42 is the distance from the bottom surface of the pressure plate 41 to the top surface of the base plate 10. After the pressure plate 41 contacts the top of the pipe, the diameter of the pipe can be obtained according to the first scale groove 42 pointed to by the first pointer 43. The sliding plate 30 has several vertically spaced second scale grooves 35. A second pointer 36 is located on the side of the sliding seat 31 adjacent to the second scale groove 35. The second scale groove 35 and the second pointer 36 cooperate. The reading of the second scale groove 35 is the distance from the center line of the pressure column 32 to the top surface of the bottom plate 10. Adjusting the height of the sliding seat 31 until the reading of the second pointer 36 pointing to the second scale groove 35 is half the reading of the first pointer 43 pointing to the first scale groove 42, the pressure column 32 is aligned with the center line of the pipe. When aligned, the center line of the pressure column 32 is coplanar with the center line of the pipe.

[0034] In the specific setup, a fixing plate 24 is provided on the mounting bracket 21, and two fixing blocks 25 are spaced apart at the bottom of the fixing plate 24. The side of the fixing block 25 adjacent to the column 20 is tangent to the surface of the column 20. In the initial state, the surfaces of the two support plates 40 are coplanar, and the connecting bracket 23 is in contact with the corresponding fixing block 25. A torsion spring is sleeved on the fixing shaft 22 corresponding to the mounting bracket 21. The torsion spring provides elasticity to the mounting bracket 21, causing the connecting bracket 23 to contact the fixing block 25. After the bending operation is completed, the torsion spring pushes the connecting bracket 23 and the support plate 40 to return to their original positions. Two connecting plates 33 are vertically spaced apart at the end of the pressure column 32 away from the sliding seat 31, and a roller 34 is vertically rotatably arranged between the two connecting plates 33.

[0035] The operating principle of a municipal pipeline inspection device in this embodiment is as follows: The pipeline is placed on the base plate 10, with its middle part in contact with the surface of the column 20 and its two sides in contact with the support plate 40. Then, the control handle 52 is rotated to drive the first threaded rod 51 to rotate, thereby moving the sliding block 45 and the pressure plate 41, so that the bottom surface of the pressure plate 41 contacts the top of the pipeline, thus restricting the pipeline. The diameter of the pipeline is obtained from the first scale groove 42 pointed to by the first pointer 43. Then, the adjustment handle 62 is rotated to drive the second threaded rod 61 to rotate, thereby moving the sliding seat 31 and the pressure column 32 until the reading of the second pointer 36 pointing to the second scale groove 35 is half the reading of the first pointer 43 pointing to the first scale groove 42. Next, the hydraulic cylinder 11 is activated to push the sliding plate 30 to move, causing the sliding seat 31 and the pressure column 32 to move and bend the pipeline. During the bending process, the support plate 40 rotates around the fixed axis 22, and the bending angle of the pipeline is determined from the rotation angle of the support plate 40.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
