Description

Technical Field

[0001] This application relates to the field of communication engineering technology, specifically to a communication transmission pipeline surveying device. Background Technology

[0002] Communication transmission is the transmission of information, which refers to the transmission and exchange of information from one place to another. When maintaining or carrying out other construction work on communication transmission pipelines, it is necessary to use surveying equipment to determine the specific location and direction of the communication transmission pipelines.

[0003] Existing communication transmission pipeline surveying equipment is used by surveyors who hold the equipment and move it around the approximate location of the pipeline to survey its location. The surveyor then adjusts the position and height of the equipment based on its display to determine the exact location of the underground pipeline. The direction is then adjusted to align with the location of another set of surveying equipment to determine the pipeline's route.

[0004] However, when surveyors use handheld surveying equipment to inspect pipelines, they need to keep the equipment at a certain height for extended periods, which can easily lead to fatigue and a heavy workload. Furthermore, the surveyor's own movements can cause slight fluctuations in the height of the equipment during the survey, affecting the accuracy of the inspection. After the equipment is moved to the designated pipeline location, its position will shift again when the direction of the equipment is adjusted. This requires re-establishing the pipeline's location after the equipment has been repositioned, resulting in a significant workload for pipeline surveying.

[0005] Therefore, it is necessary to provide a communication transmission pipeline surveying device to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0007] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is: to provide a communication transmission pipeline surveying device that can achieve the effect of positioning the height of the surveying mechanism according to the actual surveying needs, and solve the problem that the height of the surveying device fluctuates during the surveying process, affecting the surveying accuracy; at the same time, through a steering mechanism, the problem of the surveying device's position moving when adjusting the direction of the surveying device is avoided.

[0008] The technical solution adopted by this application to solve its technical problem is: a communication transmission pipeline surveying device, comprising:

[0009] The moving mechanism includes a moving base and a mounting plate mounted on the surface of the moving base. The surface of the mounting plate is provided with a first lifting groove and a second lifting groove.

[0010] The surveying mechanism is located above the mobile base. The surveying mechanism includes a surveying body and connecting blocks and a first control block located on both sides of the mounting plate. The connecting blocks are fixedly connected to the surveying body. The surface of the first control block is provided with a lifting control groove. A guide block is fixedly connected between the connecting block and the first control block. The guide block is slidably located inside the first lifting groove. Moving the position of the guide block inside the first lifting groove can change the height of the surveying body.

[0011] The steering mechanism is located below the main body of the exploration and is used to adjust the orientation of the main body of the exploration. The steering mechanism includes a positioning pin corresponding to the middle of the main body of the exploration and a connecting rod connected to the positioning pin. The connecting rod slides through the second lifting groove, and a lifting rod is fixedly connected to the end of the connecting rod away from the positioning pin.

[0012] The positioning mechanism is located on the side of the mounting plate away from the main body of the survey, and is used to fix the position of the surveying mechanism. The positioning mechanism includes a lifting plate and a positioning seat located below the lifting plate. The lifting plate and the positioning seat are fixedly connected by a connecting column.

[0013] The control mechanism includes a housing fixedly connected to the mounting plate, and a main shaft and a lifting stud disposed inside the housing. A base is fixedly installed at the bottom of the housing, and a return spring is disposed between the inner wall of the base and the lifting rod. A second control block is fixedly disposed on the surface of the main shaft, and a lifting hole and a control groove are opened on the surface of the lifting stud. The second control block is slidably disposed inside the control groove so that the lifting stud rotates synchronously when the main shaft rotates.

[0014] Furthermore, the bottom of the mobile base is equipped with multiple sets of omnidirectional wheels, and the mounting plate is fixedly connected to the mobile base. The mounting plate is set perpendicular to the mobile base and has an arc-shaped plate structure, which is used to move the position of the survey equipment during the survey.

[0015] Furthermore, the surveying mechanism is located on the side of the connecting block away from the mounting plate, and the connecting block is slidably mounted on the mounting plate.

[0016] Furthermore, the lifting control groove is located on the side of the first control block away from the mounting plate. The first control block is slidably mounted with the mounting plate. The inner wall of the lifting control groove is threaded for adjusting the lifting of the surveying mechanism.

[0017] Furthermore, a collar is fixedly connected to the end of the connecting rod. The collar is screwed to the positioning pin by threads and is used to adjust the height of the bottom end of the positioning pin from the ground.

[0018] Furthermore, a control rod is fixedly installed on the surface of the lifting plate to control the lifting and lowering of the lifting plate, and two sets of washers are sleeved on the surface of the control rod.

[0019] Furthermore, a connector is fixedly installed on the surface of the housing, and a handle is fixedly connected to the end of the connector away from the housing. The handle is used to control the movement of the exploration equipment. A fourth lifting groove is opened on one side of the housing, and the control rod slides through the fourth lifting groove. Two sets of washers are respectively set on the inner and outer sides of the fourth lifting groove. A mounting hole is opened on the top surface of the housing, and the main shaft can extend and retract through the mounting hole. A through hole is opened on the bottom surface of the housing, and the connecting column can extend and retract through the through hole.

[0020] Furthermore, a top-holding spring is fitted onto the surface of the connecting column. The top-holding spring is located between the positioning seat and the housing and is used to control the descent of the positioning seat.

[0021] Furthermore, multiple extension rods are fixedly installed at the top of the spindle to control the spindle rotation.

[0022] Furthermore, the two ends of the lifting stud are rotatably connected to the inner wall of the housing through bearings. The lifting stud engages with the threaded inner wall of the lifting control groove. The lifting hole passes through both ends of the lifting stud. The lifting rod is slidably inserted into the inside of the lifting hole. The top end of the lifting rod is attached to the bottom end of the main shaft. The lifting rod is raised and lowered by controlling the main shaft. The bottom end of the lifting rod extends into the inside of the base. A third lifting groove is opened on one side of the base. The connecting rod passes through the second and third lifting grooves and is fixedly connected to the bottom end of the lifting rod. The raising and lowering of the lifting rod drives the connecting rod to rise and fall synchronously, thereby controlling the raising and lowering of the positioning pin.

[0023] The beneficial effects of this application are: the communication transmission pipeline surveying equipment provided by this application, by setting up a height-adjustable surveying mechanism and moving the surveying mechanism through a moving mechanism, ensures that the height of the surveying mechanism remains constant during the surveying work, thus avoiding the problem of reduced surveying accuracy caused by fluctuations in the height of the surveying equipment during the surveying process.

[0024] Meanwhile, by setting up a steering mechanism, after the survey equipment reaches the pipeline's designated location, the equipment is supported by a positioning pin and rotated around the positioning pin. This avoids the problem of the survey equipment's position shifting when adjusting its orientation, thus reducing the workload of the survey work.

[0025] In addition to the purposes, features, and advantages described above, this application has other purposes, features, and advantages. These will be further described in detail below with reference to figures. Attached Figure Description

[0044] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0045] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0046] Example 1: When surveyors use handheld surveying equipment to conduct pipeline surveys, they need to keep the equipment at a certain height for a long time, which can easily lead to fatigue and a heavy workload for the surveyors. In addition, due to the swaying of the surveyors themselves, the height of the surveying equipment will fluctuate slightly during the survey, affecting the survey accuracy.

[0047] To solve the above problems, such as Figures 1-4 As shown, this application proposes a communication transmission pipeline surveying device, including a moving mechanism 1. The moving mechanism 1 is used to maintain the smooth movement of the surveying device. The moving mechanism 1 includes a moving base 11 located at the bottom and multiple sets of universal wheels 12 installed at the bottom of the moving base 11, thereby facilitating the free movement of the surveying device.

[0048] Meanwhile, a mounting plate 13 is fixedly installed on the surface of the movable base 11, and the mounting plate 13 is perpendicular to the movable base 11. A first lifting groove 14 located at the upper end is formed on the surface of the mounting plate 13. An exploration mechanism 2 is slidably disposed inside the first lifting groove 14, so that the exploration mechanism 2 can slide vertically along the first lifting groove 14. Specifically:

[0049] The surveying agency 2 includes a surveying body 21 for conducting surveying operations on pipelines. This surveying body 21 is existing technology in the field and is well-known and commonly used by professionals in the field, such as the British Reddy RD8100 and RD8200 underground pipeline detectors. It is not the focus of protection in this case, so it will not be described in detail in this case.

[0050] A connecting block 22 is fixedly installed on one side of the exploration body 21, and a guide block 23 is fixedly installed at the end of the connecting block 22 away from the exploration body 21. The guide block 23 is slidably disposed inside the first lifting groove 14, thereby moving the position of the guide block 23 inside the first lifting groove 14 and changing the height of the exploration body 21.

[0051] Meanwhile, the side of the mounting plate 13 on which the surveying mechanism 2 is installed is arc-shaped, and the position where the connecting block 22 contacts the mounting plate 13 is also arc-shaped, so that the surveying mechanism 2 can slide smoothly up and down on the mounting plate 13.

[0052] Furthermore, a first control block 24 is fixedly installed at the end of the guide block 23 away from the connecting block 22. A lifting control groove 25 is provided on the first control block 24 along the vertical direction. A first thread is provided on the inner wall of the lifting control groove 25. A control mechanism 5 is provided above the lifting control groove 25. The control mechanism 5 has a lifting stud 59. The lifting stud 59 is installed in conjunction with the first thread. Thus, by the cooperation of the lifting stud 59 and the first thread, the surveying mechanism 2 can be controlled to stay at any height.

[0053] like Figure 3 , Figures 5-6 ,and Figure 9-10 As shown, the control mechanism 5 also includes a housing 51 fixedly mounted to the mounting plate 13, and a main shaft 58 with bearings installed inside the housing 51. Meanwhile, a mounting hole 56 is provided on the top surface of the housing 51, through which the main shaft 58 passes, and a second control block 581 is fixedly provided on the surface of the main shaft 58.

[0054] A lifting hole 591 and a control groove 592 are provided on the surface of the lifting stud 59. At the same time, the second control block 581 is slidably disposed inside the control groove 592. Thus, when the main shaft 58 rotates, the lifting stud 59 can rotate synchronously through the cooperation of the second control block 581 and the control groove 592. In addition, multiple sets of extension rods 582 are fixedly installed at the top of the main shaft 58 to control the rotation of the main shaft 58.

[0055] In summary, by rotating the lifting stud 59, the first control block 24 rises or falls along the lifting control groove 25 via the lifting stud 59, which in turn moves the guide block 23 inside the first lifting groove 14, thereby achieving the rise or fall of the survey body 21. After adjusting the position of the survey body 21 to the specified height according to the survey needs, the survey body 21 is controlled to move and conduct surveys via the movable base 11 and the universal wheels 12. During the movement, the height of the survey body 21 remains constant, avoiding fluctuations in the height of the survey body 21 during the survey process, which would lead to a decrease in survey accuracy.

[0056] Furthermore, by setting the mounting plate 13 as an arc-shaped plate structure, the verticality of the connecting block 22 and the first control block 24 when sliding against the mounting plate 13 is ensured, thereby making the vertical accuracy of the survey body 21 higher when it is raised and lowered.

[0057] Example 2: When the survey equipment is moved to the pipeline location, the position of the survey equipment will move again when the direction of the survey equipment is adjusted. The pipeline location needs to be determined again after the direction of the survey equipment is adjusted, which results in a large workload for pipeline survey work.

[0058] To solve the above problems, such as Figure 1 and Figure 4 As shown, a second lifting groove 15 is provided on the mounting plate 13 below the first lifting groove 14. A steering mechanism 3 is slidably disposed in the second lifting groove 15 along the vertical direction. The steering mechanism 3 is used to adjust the direction of the surveying mechanism 2. Specifically:

[0059] like Figures 5-8 As shown, the steering mechanism 3 includes a positioning pin 34 corresponding to the center position of the survey body 21, and a connecting rod 32 connected to the positioning pin 34. The connecting rod 32 slides through the second lifting groove 15 to facilitate the up and down movement of the steering mechanism 3. The end of the connecting rod 32 is fixedly connected to a collar 33, which is threaded to the positioning pin 34 to adjust the height of the bottom end of the positioning pin 34 from the ground.

[0060] By rotating the positioning pin 34, the positioning pin 34 can rise or fall inside the collar 33, thereby adjusting the height of the bottom of the positioning pin 34 from the ground. When the ground at the survey site is relatively soft, the positioning pin 34 can be adjusted so that the bottom of the positioning pin 34 is close to the ground, so as to avoid the positioning pin 34 sinking too much into the ground and thus failing to support the survey equipment.

[0061] like Figure 3 and Figure 8 As shown, a lifting hole 591 is provided through the interior of the lifting stud 59, and a lifting rod 31 is fixedly connected to the end of the connecting rod 32 away from the positioning pin 34. The lifting rod 31 is slidably inserted into the interior of the lifting hole 591, so that the lifting rod 31 can move up and down within the lifting hole 591.

[0062] like Figures 5-6 As shown, a base 35 is fixedly installed at the bottom of the housing 51. A return spring 37 is provided between the inner wall of the base 35 and the lifting rod 31. The top end of the lifting rod 31 is attached to the bottom end of the main shaft 58, so that the lifting rod 31 can be raised and lowered by moving the main shaft 58 up and down.

[0063] Furthermore, the bottom end of the lifting rod 31 extends into the interior of the base 35. A third lifting groove 36 is opened on one side of the base 35. After the connecting rod 32 passes through the second lifting groove 15 and the third lifting groove 36, it is fixedly connected to the bottom end of the lifting rod 31. Thus, the lifting rod 31 can drive the connecting rod 32 to rise and fall synchronously, thereby controlling the rise and fall of the positioning pin 34.

[0064] In summary, by pressing the main shaft 58 to compress the lifting rod 31, the lifting rod 31 compresses the return spring 37. During the descent, the lifting rod 31 drives the connecting rod 32 to move closer to the ground, causing the bottom end of the positioning pin 34 to contact the ground, thus supporting the entire exploration equipment. The exploration equipment is then rotated around the positioning pin 34 to adjust the orientation of the exploration body 21. Since the positioning pin 34 corresponds to the middle of the exploration body 21, the position of the exploration body 21 will not change when the exploration equipment is rotated, thus avoiding the problem of the exploration equipment moving when adjusting its orientation.

[0065] Example 3: After the location of the exploration equipment is adjusted, it is necessary to position the equipment. This example specifically illustrates the structure and principle of how to position the exploration equipment. Specifically:

[0066] like Figure 1 As shown, a positioning mechanism 4 is provided on the side of the mounting plate 13 away from the survey body 21. The positioning mechanism 4 is used to fix the position of the survey body 2.

[0067] like Figures 5-11 As shown, the positioning mechanism 4 includes a lifting plate 41 slidably disposed inside the housing 51, and a positioning seat 45 disposed below the lifting plate 41. A connecting column 44 is fixedly installed between the lifting plate 41 and the positioning seat 45. A control rod 42 is fixedly installed on the surface of the lifting plate 41. The control rod 42 is used to control the lifting of the lifting plate 41, and a washer 43 is sleeved on the surface of the control rod 42.

[0068] A connector 52 is fixedly installed on the surface of the housing 51. A handle 53 is fixedly connected to the end of the connector 52 away from the housing 51. The handle 53 is used to control the movement of the exploration equipment. At the same time, a fourth lifting groove 54 is opened on one side of the housing 51. The control rod 42 slides through the fourth lifting groove 54.

[0069] The bottom surface of the housing 51 has a through hole 55, the connecting post 44 passes through the through hole 55, and a top holding spring 46 is sleeved on the surface of the connecting post 44. The top holding spring 46 is located between the positioning seat 45 and the housing 51 and is used to control the positioning seat 45 to descend.

[0070] When moving the surveying equipment, simultaneously grip the connector 52 and the control lever 42, causing the control lever 42 to move closer to the connector 52, thus separating the positioning seat 45 from the ground. At this point, the surveying equipment can be moved by pushing the handle 53. After moving the surveying equipment to the designated position, release the control lever 42. Under the action of the rebound force of the top holding spring 46, the positioning seat 45 will adhere to the ground, preventing the surveying equipment from moving on its own.

[0071] Working principle:

[0072] When using the communication transmission pipeline surveying equipment described in this case to survey communication transmission pipelines, by simultaneously gripping the control lever 42 and the connector 52, the positioning seat 45 is separated from the ground. At this time, the surveying equipment is moved by pushing the handle 53. Then, according to the display of the surveying body 21, the main shaft 58 is rotated by the extension rod 582 to adjust the surveying body 21 to the specified height. At this time, when moving the surveying equipment for surveying, the height of the surveying body 21 remains unchanged, which improves the accuracy of the survey. When the surveying equipment reaches the pipeline fixed position, the control lever 42 is released to make the positioning seat 45 fit with the ground to prevent the surveying equipment from moving on its own. Then, the extension rod 582 and the connector 52 are gripped at the same time to make the positioning nail 34 support the surveying equipment. The surveying equipment is rotated around the positioning nail 34 to adjust the orientation of the surveying body 21 to determine the direction of the pipeline.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
