Description

Technical Field

[0001] The invention relates to the technical field of deviation correction of power transmission and transformation pipelines, and in particular to a pipeline laying device for power transmission and transformation projects. Background Art

[0002] Deviation correction for power transmission and transformation pipelines refers to the technical process of correcting and adjusting the pipelines when they deviate from the designed route, position or slope during laying in power transmission or transformation projects. The purpose of deviation correction is to ensure that the pipelines are laid correctly according to the design requirements, avoid potential safety hazards in subsequent operation, and ensure construction quality and project progress.

[0003] After searching, the Chinese patent with publication number CN117878779B includes a deviation correction schematic component, an adjustment deviation correction component, an insertion positioning pile, a schematic support plate and a pipeline body. The insertion positioning pile is arranged on the ground, the schematic support plate is fixed to the top of the insertion positioning pile, the deviation correction schematic component is arranged on the schematic support plate, the adjustment deviation correction component is arranged on the ground, the adjustment deviation correction component is located at the front side of the deviation correction schematic component, and the pipeline body is arranged on the adjustment deviation correction component.

[0004] In the above patent, a deviation correction indication component is used to quickly and simply indicate the deviation of the pipeline body and the direction in which it needs to be adjusted, which greatly saves the time required for pipeline correction; further, by observing the water storage situation in the indication container, the electric push rod is controlled to extend and retract accordingly, and the claw-shaped bracket and the partition baffle synchronously drive the pipeline body to rotate at a corresponding angle, thereby realizing flexible deviation correction and adjustment of the pipeline.

[0005] However, when the above patent is in use, since the device needs to be fixed on the laying pit surface of the pipeline, it can only correct the deviation of a single section of the axial pipeline, and the installation of the curved pipeline is limited. In addition, if the overall deviation of the pipeline is to be corrected, it needs to be repeatedly disassembled and assembled. The steps are cumbersome and it is also easy to destroy the stability of the laid pipeline. In addition, the above patent judges the deviation of the pipeline by observing the water storage situation in the indicator container, and further manually controls and adjusts the calibration of the correction component. The device has a low degree of automation, and it is inevitable that judgment errors will occur by observing the water storage situation in the indicator container with the naked eye, which further makes it difficult for the device to achieve the expected correction and calibration effect.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1:

[0021] See also Figures 1 to 9 The present invention provides a technical solution: a pipeline laying device for power transmission and transformation engineering, comprising a traveling component arranged on the outer contour of a pipeline body 11, a monitoring component arranged on the traveling component, and a calibration component arranged on the traveling component, characterized in that: the number of the pipeline bodies 11 arranged is greater than or equal to two and are laid in parallel at equal intervals inside a tunnel 1; The walking assembly includes a hollow rod 2, a fixing plate 21 and a buckle portion arranged in the middle section of the tunnel 1, wherein the fixing plates 21 have two and are symmetrically fixedly connected to the two ends of the middle section of the hollow rod 2 in the radial direction; The monitoring assembly includes a fixed shaft 4 that penetrates and is rotationally connected to the bottom end of the fixed plate 21 and a connecting rod group that is transmission-connected to the buckle portion of the walking assembly, and the connecting rod group is arranged on the outer contour of the axial middle section of the fixed shaft 4; The calibration assembly includes a telescopic portion arranged inside the hollow rod 2 and a cleaning portion arranged on both horizontal sides of the bottom end of the fixing plate 21, and the cleaning portion is fixedly connected to the buckle portion of the walking assembly.

[0022] The present invention is mainly applicable to the calibration scenario of multiple pipelines laid in parallel. It determines whether the pipeline main body 11 is offset during the laying process by monitoring the distance change between the pipeline main bodies 11, and performs real-time calibration on the offset pipeline main body 11 to ensure that the multiple pipeline main bodies 11 are always in a parallel position.

[0023] The displacement of the pipeline main body 11 in the horizontal and vertical directions respectively corresponds to the telescopic part and the cleaning part of the calibration component. When the pipeline main body 11 is displaced horizontally, the monitoring component controls the telescopic part of the calibration component to start working, and the telescopic part further pulls the displaced pipeline main body 11 to move in the opposite direction of the displacement side to realize calibration reset: when the pipeline main body 11 is displaced vertically, there is a height difference between the two pipeline main bodies 11, indicating that there are foreign objects such as sand at the bottom of the pipeline main body 11 at a high point on the inner wall of the tunnel 1, causing the pipeline main body 11 to be abnormally lifted. At this time, the monitoring component controls the cleaning part of the calibration component to start working, and the cleaning part rotates and cleans the bottom end of the high-point pipeline main body 11 to remove foreign objects to realize calibration reset of the displaced pipeline main body 11. Embodiment 2:

[0024] See also Figure 3-Figure 4 This embodiment further illustrates the following on the basis of the first embodiment: The snap-fit ​​portion includes a limit ring 3, which is limit-clamped on the outer contour of the opposite surface of the pipe body 11. The side of the limit ring 3 close to the inner wall of the tunnel 1 is penetrated and rotatably connected with a snap ring 31. The opposite surface of the limit ring 3 is symmetrically provided with a limit groove 32 near the bottom end. The inside of the snap ring 31 is radially penetrated and rotatably connected with a walking wheel 33 driven by an external motor. The top of the snap ring 31 is axially penetrated and fixedly connected with a fixing pin 34. The snap ring 31 and the limit ring 3 are rotationally connected by the fixing pin 34. The contact surfaces of the snap ring 31 and the limit ring 3 are fixedly connected with friction pads 35 that are frictionally damped with each other.

[0025] Before using the device, the buckle part of the walking assembly needs to be installed on the outer contour of the pipe body 11 and the position is adjusted so that the hollow rod 2 and the fixing plate 21 are in the middle position between the two pipe bodies 11 and remain in a horizontal state. The installation process of the buckle part is as follows: Before the snap-on part is installed, the snap-on ring 31 is in a flipped state. At this time, the limit ring 3 is covered on the outer contours of the opposite surfaces of the two pipe bodies 11. Then the snap-on ring 31 is pressed down, and the snap-on ring 31 is flipped along the fixing pin 34 and also fits on the outer contour of the pipe body 11. During this process, the friction pads 35 on the opposite surfaces of the snap-on ring 31 and the limit ring 3 contact each other and generate damping friction. As the flipping angle of the snap-on ring 31 increases, the contact surface between the two friction pads 35 increases synchronously, that is, the friction resistance between the limit ring 3 and the snap-on ring 31 increases synchronously, to ensure that there will be no accidents such as structural detachment between the limit ring 3 and the snap-on ring 31 during walking, thereby improving the walking scanning quality of the device.

[0026] Through the structural design of the snap ring 31 and the limit ring 3, the walking component can adapt to a variety of different specifications of the pipe body 11, thereby effectively improving the use scenario of the device; on the other hand, for the parallel arranged pipe bodies 11, when the walking component moves to the bending position of the pipe body 11, the bending and extrusion of the pipe body 11 causes the flipping angle of the snap ring 31 on the limit ring 3 to be synchronously adjusted. At this time, the friction resistance provided by the friction pad 35 is synchronously adjusted to ensure that the walking wheel 33 is always in contact with the pipe body 11, thereby further improving the walking scanning quality of the device, and the device as a whole does not contact the bottom end of the pipe body 11 when the calibration operation is not performed, further ensuring the stability of the laid pipe body 11.

[0027] It should be noted that when the snap ring 31 is in contact with the surface of the pipe body 11 and the friction resistance provided by the friction pad 35 reaches the maximum, the walking wheel 33 and the snap ring 31 are also in contact with the surface of the pipe body 11. At this time, the external motor is started to drive the friction pad 35 to rotate. The rotation of the friction pad 35 further realizes the function of the walking component to scan along the laying direction of the pipe body 11. During this process, the remaining structures of the walking component pulling device move synchronously, and the overall center of gravity of the device is placed near the midline by adjusting the mass distribution of the hollow rod 2 and the fixed plate 21, thereby ensuring that the hollow rod 2 and the fixed plate 21 are always in a nearly horizontal state due to their own gravity balance during the walking process. Embodiment three:

[0028] See also Figure 5-Figure 6 This embodiment further illustrates the following on the basis of the second embodiment: The connecting rod group includes a transmission rod 43 which is rotatably connected to the inside of the limiting groove 32 through a pin shaft. The end of the transmission rod 43 away from the limiting ring 3 is fixedly connected to the piston 42. The axial sides of the piston 42 are rotatably connected to the inclined plates 41 through pin shafts. The axis center of the inclined plate 41 away from the piston 42 is penetrated and fixedly connected to the outer contour of the fixed shaft 4.

[0029] A transmission rope 44 extending toward the bottom end of the hollow rod 2 is fixedly connected at the axis of the piston 42, and the extension direction of the transmission rope 44 points to the fixed plate 21 opposite to the corresponding piston 42. The middle section of the transmission rope 44 passes through and is limitedly slidably connected to the inside of the fixed plate 21. The end of the transmission rope 44 away from the piston 42 is fixedly connected to a fixing ring 46, and the top of the fixing ring 46 is fixedly connected to a limiting shaft 45. The top of the limiting shaft 45 is rotationally limitedly connected to a driving wheel 47. The driving wheel 47 is driven by an external motor and is located inside the hollow rod 2. A locating pin 48 is laterally fixedly connected at a position near the bottom end of the middle section of the hollow rod 2 on the outer contour of the limiting shaft 45. The limiting shaft 45 and the hollow rod 2 are rotationally connected via the locating pin 48. Adjustment grooves for radial fixed axis deflection of the limiting shaft 45 and the locating pin 48 are provided on both vertical sides of the outer contour of the middle section of the hollow rod 2.

[0030] The connecting rod groups are provided with two groups and are symmetrically distributed along the axis of the driving wheel 47. The transmission rope 44 is set to an extreme relaxation state. The surface of the driving wheel 47 is provided with a pressure sensor and the pressure sensor controls the start and stop and the rotation direction of the motor.

[0031] It can be seen from the second embodiment that in the process of the travel wheel 33 driving the limit ring 3 and the buckle ring 31 to move along the laying direction of the pipeline body 11, the monitoring component is pulled and moves synchronously. When the distance between the two parallel pipeline bodies 11 changes, it indicates that the laying direction of one pipeline body 11 is offset. At this time, the monitoring component works synchronously and controls the calibration component to start the reset calibration operation. The working process of the monitoring component is as follows: When the horizontal distance between the two pipe bodies 11 changes, the limit ring 3 and the snap ring 31 on the offset side synchronize the offset change of the pipe body 11, and the transmission rod 43 and the piston 42 at the corresponding position are synchronously pulled by the limit ring 3, causing the inclined plate 41 to deflect. At this time, the inclined plate 41 synchronously pulls the transmission rope 44 and further pulls the fixing ring 46, causing the limit shaft 45 to deflect along the positioning pin 48 toward the opposite fixed axis of the pulling transmission rope 44. Furthermore, the fixed axis deflection of the limit shaft 45 causes the driving wheel 47 to contact the telescopic part of the calibration component at the corresponding position. At this time, the pressure on the surface of the driving wheel 47 increases, and the pressure sensor controls the motor to start and drive the driving wheel 47 to rotate. The rotation of the driving wheel 47 further drives the telescopic part to move synchronously to realize the calibration and reset operation of the offset pipe body 11.

[0032] Among them, the offset direction of the pipeline body 11 determines the deflection direction of the corresponding inclined plate 41, and the deflection direction of the inclined plate 41 further determines the rotation direction of the driving wheel 47. When the pipeline body 11 deviates to the outside, the inclined plate 41 is pulled to deflect it in the horizontal direction. At this time, the driving wheel 47 rotates counterclockwise to control the contraction of the telescopic part and further reset the offset pipeline body 11; when the pipeline body 11 deviates to the inside, the inclined plate 41 is pulled to deflect it in the vertical direction. At this time, the driving wheel 47 rotates clockwise to control the extension of the telescopic part to achieve pulling and resetting.

[0033] It should be noted that since the transmission rope 44 is set to an extreme relaxation state, when one of the transmission ropes 44 pulls the fixed ring 46 to cause the limit shaft 45 to deflect, the other transmission rope 44 is synchronously pulled by the fixed ring 46 but its tension is less than the transmission rope 44 pulled by the inclined plate 41. Therefore, the resistance generated on the fixed ring 46 has a negligible effect on the overall structural transmission of the monitoring component.

[0034] On the other hand, along with the rotation of the driving wheel 47, the offset pipe body 11 is gradually reset. At this time, the inclined plate 41 is synchronously reset under the action of the corresponding piston 42, the transmission rod 43 and the limit ring 3, resulting in the end of the pulling of the transmission rope 44 by the inclined plate 41. The driving wheel 47 and the limit shaft 45 rotate to the initial position again and the contact between the driving wheel 47 and the telescopic part is disengaged. After the disengagement, the surface pressure sensor of the driving wheel 47 shows zero, so that it controls the driving wheel 47 to stop rotating, thereby completing the automatic calibration and reset process of the device.

[0035] When the driving wheel 47 rotates, since the deflection direction of the pipeline body 11 cannot be known, the initial rotation direction of the driving wheel 47 is set to be clockwise. As the driving wheel 47 rotates clockwise, if the indication of the pressure sensor on the surface of the driving wheel 47 becomes smaller, it means that the offset pipeline body 11 is gradually reset. The driving wheel 47 continues to rotate clockwise until the driving wheel 47 is out of contact with the telescopic part. If the indication of the pressure sensor on the surface of the driving wheel 47 becomes larger, it means that the offset degree of the offset pipeline body 11 is further increased. At this time, the pressure sensor of the driving wheel 47 controls the driving wheel 47 to rotate counterclockwise, thereby realizing the calibration and reset of the offset pipeline body 11. Embodiment 4:

[0036] See also Figure 7-Figure 8 This embodiment further illustrates the following on the basis of the third embodiment: The telescopic part includes a rack 5 that is limitedly slidably arranged on both sides of the axial direction of the inner contour of the hollow rod 2, and the rack 5 is intermittently transmission connected to the driving wheel 47. The end of the rack 5 extending out of the hollow rod 2 is fixedly connected to a telescopic plate 51, and the other end of the telescopic plate 51 is penetrated and sleeved with a lifting rod 52, and the bottom end of the lifting rod 52 is fixedly connected to the center of the top of the limiting ring 3.

[0037] The cleaning part includes a fixed seat 58 fixedly connected to the radial sides of the bottom end of the opposite surface of the fixed plate 21, and a telescopic shaft 57 extending toward the limiting ring 3 is penetrated and slidably connected at the center of the fixed seat 58. The telescopic shaft 57 is connected to a fixed disk 55 for limited rotation at one end away from the fixed seat 58. A cleaning roller 56 in the same direction as the pipeline body 11 is fixedly connected to the outer contour of the fixed disk 55. A threaded shaft 54 ​​is penetrated and transmission-connected at the axial center of the fixed disk 55. A positioning rod 53 is fixedly connected to the top end of the threaded shaft 54, and the other end of the positioning rod 53 is fixedly connected to the outer contour of the lifting rod 52.

[0038] The helix angle of the threaded shaft 54 ​​is greater than forty-five degrees and the contact surface between the threaded shaft 54 ​​and the fixed plate 55 is a smooth surface, and there is no contact between the bottom end of the cleaning roller 56 and the inner wall of the tunnel 1.

[0039] It can be seen from the third embodiment that, for the horizontal deviation of the pipeline body 11, the monitoring component controls the telescopic part of the calibration component to work synchronously to achieve the reset calibration of the deviated pipeline body 11. The specific working process of the telescopic part is as follows: When the driving wheel 47 rotates clockwise, the driving wheel 47 has been deflected by the fixed axis under the action of the limiting shaft 45 and meshed with the rack 5 on the corresponding side. At this time, the clockwise rotation of the driving wheel 47 drives the rack 5 and the telescopic plate 51 to gradually extend from the inside of the hollow rod 2. The telescopic plate 51 further controls the synchronous movement of the lifting rod 52 and the limiting ring 3. At this time, the limiting ring 3 begins to squeeze the pipeline body 11 on the offset side and causes the pipeline body 11 to be displaced. The displacement of the pipeline body 11 is further transmitted through the structure of the monitoring component and is finally reflected in the change of the indication of the pressure sensor on the surface of the driving wheel 47. If the pressure sensor reading on the surface of the driving wheel 47 becomes larger, it means that the offset degree of the offset pipeline body 11 is further increased. At this time, the driving wheel 47 can rotate counterclockwise to achieve the calibration and reset of the pipeline body 11; if the pressure sensor reading on the surface of the driving wheel 47 becomes smaller, it means that the offset pipeline body 11 is gradually reset. At this time, the driving wheel 47 can continue to rotate clockwise.

[0040] On the other hand, when the pipeline body 11 is offset in the vertical direction, that is, there is a height difference between the two parallel pipeline bodies 11, indicating that one of the pipeline bodies 11 is abnormally raised by some gravel retained during the excavation of the tunnel 1. At this time, the cleaning part of the calibration component works synchronously to sweep away the gravel at the bottom of the abnormally raised pipeline body 11 to achieve reset calibration of the offset pipeline body 11. The specific working process of the cleaning part is as follows: When a height difference occurs between the pipeline bodies 11, the lifting rod 52 corresponding to the offset side pipeline body 11 rises synchronously, while the telescopic plate 51 is still in a nearly horizontal state under the gravity balance distribution of the hollow rod 2 and the fixed plate 21, that is, the lifting rod 52 retracts back into the telescopic plate 51 and the lifting rod 52 drives the positioning rod 53 and the threaded shaft 54 ​​to rise accordingly, while the fixed seat 58 also remains stationary under the gravity balance distribution of the fixed plate 21 and the hollow rod 2, that is, the vertical heights of the fixed seat 58, the telescopic shaft 57, the fixed plate 55 and the cleaning roller 56 remain unchanged. At this time, relative movement occurs between the threaded shaft 54 ​​and the fixed plate 55. Due to the transmission connection between the threaded shaft 54 ​​and the fixed plate 55, the lifting and lowering of the threaded shaft 54 ​​further causes the fixed plate 55 to rotate, and the fixed plate 55 drives the cleaning roller 56 to rotate synchronously to achieve the sand and gravel cleaning operation at the bottom end of the offset pipeline body 11.

[0041] On the other hand, due to the limiting sliding connection between the fixed seat 58 and the telescopic shaft 57, when the pipeline body 11 is offset in the horizontal direction, the pipeline body 11 drives the limiting ring 3, the positioning rod 53 and the cleaning part as a whole to be synchronously offset horizontally. At this time, the fixed seat 58 is fixed under the action of the hollow rod 2 and the fixed plate 21, that is, there is relative movement between the fixed seat 58 and the telescopic shaft 57, so as to maintain the horizontal offset of the pipeline body 11 without affecting the structural movement of the cleaning part, thereby causing the device to misjudge the offset direction of the pipeline body 11 and affect the calibration effect.

[0042] It should be noted that since the helix angle of the threaded shaft 54 ​​is greater than forty-five degrees and the contact surface between the threaded shaft 54 ​​and the fixed disk 55 is a smooth surface, that is, the friction resistance between the threaded shaft 54 ​​and the fixed disk 55 is set to the minimum, and there is no self-locking between the threaded shaft 54 ​​and the fixed disk 55, the sensitivity of the device during the vertical offset calibration of the pipeline body 11 is further guaranteed.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
