A portable construction engineering detector

Abstract

This application relates to a portable construction engineering detector, specifically in the field of petrochemical pipeline construction technology. It includes a primary ruler, a secondary ruler, and a hinge. The primary and secondary rulers are rotatably connected via the hinge. It also includes a locking component for locking the primary and secondary rulers in their extended or closed states. This application utilizes two sets of forward and reverse motors, two sets of threaded columns, and two sets of movable plates. Before testing, based on actual needs, the corresponding forward and reverse motors within the rulers are activated using a control component. The output of the forward and reverse motors drives the threaded columns to rotate. Because the movable plates are threadedly engaged with the threaded columns and slidably located inside the rulers, the rotation of the threaded columns drives the movable plates to extend or retract along the axial direction. This eliminates the need to carry multiple detectors of different lengths or perform multiple measurements by splicing them together, effectively solving the problem of poor adaptability of existing fixed-length rulers. It significantly reduces the carrying burden on workers and the frequency of tool replacements, thereby improving the efficiency of petrochemical pipeline inspection.

Description

Technical Field

[0001] This application relates to the field of petrochemical pipeline construction technology, and in particular to a portable construction engineering detector. Background Technology

[0002] Used to ensure the installation accuracy of petrochemical pipelines and avoid safety hazards or economic losses caused by pipeline installation errors. The construction of petrochemical pipelines has extremely high precision requirements, especially in the inspection of key parts such as pipeline welding joints, laying slopes, and support spacing. Precision control is directly related to the safe operation of the system.

[0003] An existing patent (publication number: CN220472639U) discloses a portable construction engineering detector, including a first ruler body, a second ruler body, and a hinge, as well as a locking component. The locking component includes a limiting plate and a return spring. A mounting rod is fixed to the outer side of the second ruler body, and a limiting plate is fixed to the extended end of the mounting rod. The return spring is sleeved on the mounting rod. A positioning short post is fixed to the outer side of the first ruler body, and a positioning hole is provided in the limiting plate for the positioning short post to pass through. This detector can be locked in both the first and second ruler bodies in the fully extended and fully closed states through the locking component, exhibiting high stability. Furthermore, a single component can achieve locking in both states of the first and second ruler bodies, resulting in low cost. Locking when the first and second ruler bodies are fully extended also improves the safety of use and portability. However, while the aforementioned patented device optimizes portability by using a hinge to close and open the ruler, and effectively improves the stability of the closed or open state with the help of a locking component, solving the problems of easy loosening when closed and easy shaking when open of traditional detectors, it still uses a fixed-length ruler structure. In practical applications in petrochemical pipeline construction inspection scenarios, facing diverse inspection needs (such as inspection of pipe bodies of different diameters, measurement of long-distance pipeline spans, and inspection of pipe interfaces in confined spaces), a fixed-length ruler is difficult to adapt to different scenarios: when inspecting large-diameter pipes, the ruler length is insufficient and may not be able to cover the inspection area; when inspecting pipe interfaces in confined spaces, an excessively long ruler is difficult to insert for operation; when measuring long-distance pipeline spans, multiple splicing measurements are required, which not only increases the risk of errors but also affects inspection efficiency. Therefore, a portable construction engineering detector is proposed. Utility Model Content

[0004] The purpose of this application is to provide a portable construction engineering detector that is adaptable to diverse testing scenarios in petrochemical pipelines and improves testing efficiency.

[0005] This application provides a portable construction engineering detector with the following technical solution: it includes a first ruler body, a second ruler body, and a hinge. The first ruler body and the second ruler body are rotatably connected by the hinge. It also includes a locking component for locking the first ruler body and the second ruler body in an open or closed state. It further includes two sets of forward and reverse motors, two sets of threaded columns, and two sets of movable plates. The two sets of forward and reverse motors are respectively installed inside the first ruler body and the second ruler body. The two sets of threaded columns are respectively connected to the output ends of the two sets of forward and reverse motors. The two sets of movable plates are respectively threadedly engaged with the two sets of threaded columns. The two sets of movable plates are respectively slidably disposed inside the first ruler body and the second ruler body. The movable plates can extend or retract into the corresponding ruler body along the axial direction of the threaded columns. By adopting the above technical solution, and by setting up two sets of forward and reverse motors, two sets of threaded columns, and two sets of movable plates, while retaining the first and second ruler bodies, hinges, and locking components, the forward and reverse motors can drive the threaded columns to rotate, causing the movable plates that are threadedly engaged with them to extend or retract into the ruler body along the axis, breaking the limitations of existing fixed-length ruler bodies. With the rotation of the hinges and the state locking of the locking components, stability can be achieved when the ruler body is unfolded for testing, and the movable plates can be extended and retracted to adapt to the diverse testing scenarios of petrochemical pipelines. There is no need to carry multiple detectors, reducing the carrying burden and improving the testing adaptability.

[0006] Preferably, sliders are fixedly connected to the upper and lower sides of the two sets of movable plates near the two sets of forward and reverse motors, and the inside of the first ruler and the second ruler are provided with sliding grooves, and the sliders are movably connected inside the sliding grooves.

[0007] By adopting the above technical solution, a slider is set at the end of the movable plate near the forward and reverse motors, and a groove is opened inside the first and second rulers. When the movable plate extends or retracts, the slider slides along the groove, which can limit the radial displacement of the movable plate and avoid length adjustment deviation or structural jamming caused by the displacement of the movable plate. It ensures that the movable plate always moves stably along the axis of the threaded column, ensuring the accuracy of the ruler length adjustment, which meets the high-precision detection requirements of key parts such as welding joints and support spacing in petrochemical pipelines.

[0008] Preferably, it also includes a control component, which is fixedly connected to the surface of a ruler body and electrically connected to the two sets of forward and reverse motors, for independently controlling the start, stop and rotation direction of the two sets of forward and reverse motors.

[0009] By adopting the above technical solution, and by setting a control component fixed on the surface of the first ruler body, and electrically connecting the control component to two sets of forward and reverse motors, the operator can independently control the start, stop, and rotation direction of the two sets of forward and reverse motors through the control component, without the need to manually adjust the length of the movable plate. This not only allows for the separate control of the extension and retraction states of the movable plates inside the first and second ruler bodies, adapting to the different requirements for the length of the two sets of ruler bodies in different testing scenarios, but also simplifies the operation process, reduces errors caused by manual intervention, and improves testing efficiency.

[0010] Preferably, both the first and second rulers are equipped with motor protection structures inside. The motor protection structures are wrapped around the outside of the corresponding forward and reverse motors to isolate the influence of dust or moisture inside the rulers on the forward and reverse motors.

[0011] By adopting the above technical solution, and by setting up a motor protection structure inside the No. 1 and No. 2 rulers to enclose the forward and reverse motors, dust or moisture that may enter the rulers can be isolated, preventing the forward and reverse motors from malfunctioning due to impurities. This is suitable for the complex environment of petrochemical plant areas where there is a lot of dust and moisture, ensuring the stable operation of the forward and reverse motors, extending the service life of the motors, and improving the overall durability of the device.

[0012] Preferably, both sets of movable plates have protective parts at their extended ends. The protective parts are made of elastic material and are used to prevent the ends of the movable plates from rigidly colliding with the object being tested when they extend.

[0013] By adopting the above technical solution, and by setting a protective part of elastic material at the extended end of the movable plate, the protective part can buffer the impact force when the movable plate extends and contacts the petrochemical pipeline, avoiding rigid collision between the end of the movable plate and the pipeline; this not only prevents damage to the pipeline surface from affecting subsequent use, but also avoids the deformation of the end of the movable plate due to collision, which would lead to a decrease in detection accuracy, thereby reducing safety hazards and equipment wear during the detection process.

[0014] Preferably, the outer surface of both sets of movable plates is provided with an identification structure, which is used to indicate the extension length status of the movable plate.

[0015] By adopting the above technical solution and setting a marking structure on the outer surface of the movable plate, the extension length of the movable plate can be intuitively indicated, and the staff does not need to use additional measuring tools to judge the length. This avoids detection errors caused by inaccurate length estimation. Especially when measuring the span of long-distance pipelines, the total length of the ruler can be determined without multiple splicing measurements, reducing the risk of errors and ensuring the accuracy of petrochemical pipeline inspection data.

[0016] Preferably, the openings of the receiving cavities of the first and second rulers are provided with sealing elements. The sealing elements are sleeved on the outside of the corresponding movable plates and slide against the movable plates to prevent external dust or liquid from entering the receiving cavity.

[0017] By adopting the above technical solution, by setting a sealing element on the outside of the movable plate at the opening of the receiving cavity of the first and second rulers, and by having the sealing element slide and fit with the movable plate, external dust, oil or liquid can be blocked from entering the receiving cavity; impurities are prevented from adhering to the threaded column or the sliding mating surface of the movable plate, preventing structural jamming or wear, further adapting to the complex environment of the petrochemical plant area, and extending the service life of the internal structure of the device.

[0018] Preferably, the surface of the second ruler is provided with a handle.

[0019] By adopting the above technical solution and setting a handle on the surface of the second ruler, the staff can easily lift the device when carrying it. In particular, after the device is closed by the hinge and the movable plate is retracted into the ruler, the overall size is compact, and the handle can improve the convenience of carrying it. It is suitable for the needs of mobile inspection in multiple areas of petrochemical plants, reduces the inconvenience during carrying, and improves the flexibility of operation.

[0020] In summary, this application includes at least one of the following beneficial technical effects: This portable construction engineering detector features two sets of forward and reverse motors, two sets of threaded columns, and two sets of movable plates. Before testing, the corresponding forward and reverse motors within the ruler are activated using the control components, based on actual needs. The outputs of the forward and reverse motors drive the threaded columns to rotate. Because the movable plates are threadedly engaged with the threaded columns and slidably located inside the ruler, the rotation of the threaded columns drives the movable plates to extend or retract along the axial direction. This eliminates the need to carry multiple detectors of different lengths or to perform multiple splicing measurements, effectively solving the problem of poor adaptability of existing fixed-length rulers. It significantly reduces the carrying burden on staff and the frequency of tool replacements, thereby improving the efficiency of petrochemical pipeline inspection. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0024] Example 1: A portable construction project detector, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a first ruler body 1, a second ruler body 2, and a hinge 3. The first ruler body 1 and the second ruler body 2 are rotatably connected via the hinge 3. It also includes a locking assembly 4 for locking the first ruler body 1 and the second ruler body 2 in their open or closed states. Furthermore, it includes two sets of forward and reverse motors 5, two sets of threaded posts 6, and two sets of movable plates 7. The two sets of forward and reverse motors 5 are respectively installed inside the first ruler body 1 and the second ruler body 2. The two sets of threaded posts 6 are respectively connected to the output ends of the two sets of forward and reverse motors 5. The two sets of movable plates 7 are threadedly engaged with the two sets of threaded posts 6, and the two sets of movable plates 7 are slidably disposed inside the first ruler body 1 and the second ruler body 2. The movable plates 7 can move along the threaded posts 6. Extending or retracting along the axis into the corresponding ruler body, the device is equipped with two sets of forward and reverse motors 5, two sets of threaded columns 6, and two sets of movable plates 7. It retains ruler body 1, ruler body 2, hinge 3, and locking assembly 4. The forward and reverse motors 5 can drive the threaded columns 6 to rotate, causing the movable plates 7, which are threadedly engaged with them, to extend or retract along the axis into the ruler body, breaking the limitations of existing fixed-length ruler bodies. With the rotation of hinge 3 and the state locking of locking assembly 4, it can achieve stability when the ruler body is unfolded for testing, and can also adapt to the diverse testing scenarios of petrochemical pipelines through the extension and retraction of movable plates 7. It eliminates the need to carry multiple detectors, reduces the carrying burden, and improves testing adaptability.

[0025] Reference Figure 1 , Figure 2 and Figure 4Two sets of movable plates 7 are fixedly connected to sliders 8 on both the upper and lower sides of the end near the two sets of forward and reverse motors 5. Slide grooves 9 are opened inside the first ruler body 1 and the second ruler body 2, and the sliders 8 are movably connected inside the slide grooves 9. A control component 10 is also included, which is fixedly connected to the surface of the first ruler body 1 and electrically connected to the two sets of forward and reverse motors 5. The control component 10 is used to independently control the start, stop, and rotation direction of the two sets of forward and reverse motors 5. By setting sliders 8 at the end of the movable plate 7 near the forward and reverse motors 5 and opening slide grooves 9 inside the first ruler body 1 and the second ruler body 2, the sliders 8 slide along the slide grooves 9 when the movable plate 7 extends or retracts, which can limit the radial displacement of the movable plate 7 and prevent length adjustment deviation or structural jamming caused by the displacement of the movable plate 7. To ensure the stable movement of the movable plate 7 along the axis of the threaded column 6, the accuracy of the ruler length adjustment is guaranteed, meeting the high-precision inspection requirements of key parts such as welded joints and support spacing in petrochemical pipelines. By setting a control component 10 fixed on the surface of the first ruler 1, and electrically connecting the control component 10 to two sets of forward and reverse motors 5, the operator can independently control the start, stop, and rotation direction of the two sets of forward and reverse motors 5 through the control component 10, without the need to manually adjust the length of the movable plate 7. It can control the extension and retraction state of the movable plate 7 in the first ruler 1 and the second ruler 2 respectively, adapting to the different requirements of the length of the two sets of rulers in different inspection scenarios, simplifying the operation process, reducing errors caused by manual intervention, and improving inspection efficiency.

[0026] Reference Figure 1 , Figure 2 and Figure 5 Both ruler body 1 and ruler body 2 are equipped with motor protection structures 11 inside. These structures 11 enclose the corresponding forward and reverse motors 5, isolating them from the influence of dust or moisture inside the ruler body. The extended ends of both sets of movable plates 7 are equipped with protective parts 12, which are made of elastic material to prevent rigid collisions between the ends of the movable plates 7 and the object being detected when they extend. By providing motor protection structures 11 inside ruler body 1 and ruler body 2 to enclose the forward and reverse motors 5, dust or moisture that may enter the ruler body can be isolated, preventing damage to the forward and reverse motors 5. Impurities can cause malfunctions; adaptable to the complex environment of petrochemical plants where there is a lot of dust and moisture, ensuring the stable operation of the forward and reverse motors 5, extending the service life of the motors, and improving the overall durability of the device. By setting a protective part 12 of elastic material at the extended end of the movable plate 7, when the movable plate 7 extends and contacts the petrochemical pipeline, the protective part 12 can buffer the impact force and avoid rigid collision between the end of the movable plate 7 and the pipeline; it not only prevents damage to the pipeline surface from affecting subsequent use, but also avoids the deformation of the end of the movable plate 7 due to collision, which would lead to a decrease in detection accuracy, thereby reducing safety hazards and device wear during the detection process.

[0027] Reference Figure 1 , Figure 2 and Figure 3Both sets of movable plates 7 have marking structures 13 on their outer surfaces. These marking structures 13 indicate the extension length of the movable plates 7. The openings of the receiving cavities of both ruler body 1 and ruler body 2 are equipped with sealing elements 14. These sealing elements 14 are fitted onto the outer side of the corresponding movable plates 7 and slide against them, preventing external dust or liquid from entering the receiving cavity. Ruler body 2 has a handle 15 on its surface. By using the marking structures 13 on the outer surfaces of the movable plates 7, the extension length of the movable plates 7 can be clearly indicated, eliminating the need for additional measuring tools to determine the length. This avoids detection errors caused by inaccurate length estimation, especially in long-distance pipeline span measurements. The total length of the ruler can be determined without multiple measurements, reducing error risks and ensuring the accuracy of petrochemical pipeline inspection data. By installing a sealing element 14 on the outside of the movable plate 7 at the opening of the receiving cavity of the first ruler body 1 and the second ruler body 2, and by slidingly fitting the sealing element 14 with the movable plate 7, external dust, oil, or liquid can be prevented from entering the receiving cavity; this prevents impurities from adhering to the threaded column 6 or the sliding mating surface of the movable plate 7, preventing structural jamming or wear, further adapting to the complex environment of the petrochemical plant area, and extending the service life of the internal structure of the device. By installing a handle 15 on the surface of the second ruler body 2, the staff can easily lift the device when carrying it. Especially after the device is closed by the hinge 3 and the movable plate 7 is retracted into the ruler body, the overall volume is compact, and the handle 15 can improve the convenience of carrying it; this adapts to the needs of multi-area mobile detection in the petrochemical plant area, reduces the inconvenience during carrying, and improves the flexibility of operation.

[0028] In this embodiment, by setting up two sets of forward and reverse motors 5, two sets of threaded columns 6, and two sets of movable plates 7, before testing, the forward and reverse motors 5 in the corresponding ruler body are started by the control component 10 according to actual needs. The output end of the forward and reverse motors 5 drives the threaded columns 6 to rotate. Since the movable plates 7 are threadedly engaged with the threaded columns 6 and are slidably located inside the ruler body, the rotation of the threaded columns 6 can drive the movable plates 7 to extend or retract along the axial direction. There is no need to carry multiple detectors of different lengths, nor is it necessary to splice and measure multiple times. This effectively solves the problem of poor adaptability of existing fixed-length rulers, significantly reduces the burden on workers and the frequency of tool replacement, and improves the efficiency of petrochemical pipeline inspection.

[0029] The implementation principle of this application embodiment is as follows: According to the requirements of the testing scenario, the operator rotates ruler 1 and ruler 2 via hinge 3. If testing is required, both are rotated to fully unfold or a specific testing angle, and locking component 4 is used to lock the relative positions of ruler 1 and ruler 2, preventing the rulers from shaking during testing. If storage and carrying are required, both are rotated to a fully closed state and fixed again by locking component 4, ensuring that the rulers are tight and secure after closing, laying a stable foundation for subsequent carrying or length adjustment. When the testing scenario requires adaptation to different sizes, a command is issued through control component 10 on the surface of ruler 1. If the ruler length needs to be extended, control component 10 is activated. Corresponding to the forward and reverse motors 5 inside the ruler body, the output end of the forward and reverse motors 5 drives the threaded column 6 to rotate in the forward direction; because the movable plate 7 is threadedly engaged with the threaded column 6, and the slider 8 of the movable plate 7 near the forward and reverse motor 5 is embedded in the slide groove 9 inside the ruler body, the forward rotation of the threaded column 6 drives the movable plate 7 to extend out of the ruler body receiving cavity along the axis of the threaded column 6 until it reaches the length required for testing; if it is necessary to shorten the length of the ruler body, the control component 10 controls the forward and reverse motors 5 to rotate in the reverse direction, and the reverse rotation of the threaded column 6 drives the movable plate 7 to retract along the slide groove 9 into the ruler body receiving cavity, reducing the overall space occupied by the ruler body and making it easier to operate in narrow areas; throughout the entire adjustment process, the marking structure 13 on the outer surface of the movable plate 7 The system provides real-time indication of the extended length, allowing staff to visually determine if the length is suitable without additional measurement. The motor protection structure 11 always surrounds the outside of the reversible motor 5, isolating any dust or moisture that may remain inside the ruler during startup, shutdown, and operation, preventing impurities from affecting the motor's operational stability. When the movable plate 7 extends or retracts, the seals 14 at the openings of the receiving cavities of ruler 1 and ruler 2 always slide against the outside of the movable plate 7, preventing external dust, oil, or liquids from entering the receiving cavity and protecting the sliding fit between the threaded column 6 and the movable plate 7, preventing jamming or wear caused by impurities. When the device extends to contact the object being inspected, the elastic protective part 12 at its extended end first contacts the pipe surface. Through its own elasticity, it buffers the impact force and avoids a rigid collision between the metal end of the movable plate 7 and the pipe. This protects the pipe surface from damage and prevents deformation of the end of the movable plate 7 from affecting the inspection accuracy. When the inspection is completed or the inspection area needs to be moved, the movable plate 7 is first completely retracted into the first ruler body 1 and the second ruler body 2 through the control component 10. Then, the two sets of ruler bodies are closed by the hinge 3 and fixed by the locking component 4. The staff can easily lift the device through the handle 15 on the surface of the second ruler body 2, reducing the burden on the hands when carrying it. This is suitable for the needs of multi-area mobile inspection in petrochemical plant areas.
