Description

Technical Field

[0001] This application relates to the field of pipeline construction surveying, and in particular to a surveying instrument for pipeline layout during construction. Background Technology

[0002] In building construction, pipeline layout is crucial, as its rationality and accuracy directly affect project quality and performance. With the continuous development of the construction industry, the requirements for the accuracy and efficiency of pipeline layout are becoming increasingly stringent. In actual construction, it is sometimes necessary to lay pipelines at an angle on slopes with significant height differences. Therefore, developing high-precision, high-efficiency measuring instruments for pipeline layout is of significant practical importance.

[0003] In traditional construction pipeline layout surveying, levels and theodolites are often used to determine the position and level of individual pipes. Construction workers perform multiple operations at different locations to determine the approximate position and level of the pipeline. The string method is also used, which involves pulling a thin string to determine the direction and level of the pipeline.

[0004] However, traditional measurement methods have significant drawbacks. Levels and theodolites are cumbersome to operate and have low measurement efficiency; while the string method is simple, it is difficult to guarantee the accuracy of pipe layout. More importantly, when pipes need to be laid at an angle on a slope with height differences, these methods cannot quickly and accurately simulate the layout axes of multiple pipes. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this application provides a measuring instrument for pipeline layout in construction. For pipelines arranged on an inclined slope, it can emit light while ensuring the positioning accuracy of the pipeline, and simulate the position of multiple pipeline axes at one time, thereby improving the pipeline layout efficiency.

[0006] This application is achieved through the following technical solution: A measuring instrument for construction pipeline layout includes: A bidirectional leveling assembly includes a connecting plate. At least three spherical limiting grooves are evenly distributed circumferentially on the lower end face of the connecting plate. An adjusting member abuts in the spherical limiting groove and the adjusting member is used to drive the connecting plate to keep it horizontal. A pipe positioning component is mounted on a connecting plate and is capable of emitting light and adjusting the emission angle of the light to drive the light to simulate the axis of the pipe. A height adjustment device is used to adjust the bidirectional leveling component to a set height.

[0007] By adopting the above technical solution, the lower end face of the connecting plate is provided with at least three spherical limiting grooves, and an adjusting component abuts in the spherical limiting groove. The end of the adjusting component that abuts in the spherical limiting groove is also spherical, which can provide floating support and positioning for the connecting plate. By adjusting the extension length of the adjusting component, the tilt angle of the connecting plate can be adjusted, realizing rapid bidirectional leveling of the connecting plate on different slopes. The pipe positioning component can emit light to locate the axis of multiple pipes. For pipes laid on slopes, the axis of the laid pipes can be simulated by adjusting the emission angle, reducing the frequency of manual measurement and improving construction efficiency. The height adjustment device can adjust the bidirectional leveling component to a set height to achieve a wide range of height adjustment.

[0008] Optionally, the adjusting element is a threaded rod, which is threadedly connected to the height adjusting device.

[0009] By adopting the above technical solution, the adjusting component uses a threaded rod, which can keep the connecting plate horizontal by adjusting the extension length of the threaded rod. At the same time, the threaded rod has a simple structure, low cost, and facilitates the function of adjusting the extension length of the adjusting component.

[0010] Optionally, the adjusting component is an electric telescopic rod, the fixed end of which is fixed on the height adjusting device, and the free end abuts against the spherical limiting groove.

[0011] By adopting the above technical solution, the electric telescopic rod can keep the connecting plate horizontal by adjusting the extension length. The electric telescopic rod is easy to automate and can more conveniently adjust the horizontal state of the connecting plate. The fixed end of the electric telescopic rod is fixed on the height adjustment device to ensure stable connection, and the free end abuts in the spherical limiting groove, which can flexibly adapt to the angle change of the connecting plate.

[0012] Optionally, the pipe positioning assembly includes a rotating plate and a positioning rod fixed on the connecting plate. The positioning rod is provided with a groove and a scale for marking the rotation position of the rotating plate. A support rod is fixed on the connecting plate. One end of the rotating plate is hinged to the support rod, and the other end is slidably connected in the groove.

[0013] By adopting the above technical solution, one end of the rotating plate is hinged to the support rod, and the other end is slidably connected in the groove, so that the rotating plate can flexibly adjust the angle and ensure that the axis of the rotating plate is parallel to the slope. The scale on the positioning rod can mark the rotation position of the rotating plate, which makes it easy for the operator to accurately control the rotation angle of the rotating plate.

[0014] Optionally, the groove has an arc-shaped structure, and the scale is an angle scale with an arc-shaped structure.

[0015] By adopting the above technical solution, using an arc-shaped angle ruler as a scale, and in conjunction with an arc-shaped sliding groove, the rotation angle of the rotating plate can be displayed intuitively, making it easier for construction personnel to accurately adjust the light emission angle to simulate the pipeline axis and improve measurement efficiency.

[0016] Optionally, the slide has a linear structure, and the scale is a linear scale.

[0017] By adopting the above technical solution, the linear scale on the positioning rod can display the displacement of the rotating plate in the vertical direction, and the linear scale is easy to manufacture and install.

[0018] Optionally, the rotating plate is equipped with a laser emitter for emitting light to position the pipeline.

[0019] By adopting the above technical solution, a laser emitter is set on the rotating plate to emit light for positioning the pipe positions, which can simulate the positions of multiple pipe axes at one time, thereby improving the efficiency of pipe layout.

[0020] Optionally, the rotating plate is equipped with a communication positioning module for measuring the elevation of the laser emitter.

[0021] By adopting the above technical solution, the communication positioning module on the rotating plate can easily read the elevation of the laser emitter, thereby determining the angle at which the rotating plate needs to be rotated, and improving the accuracy of the laser emitted by the laser emitter in simulating the axis of the pipeline.

[0022] Optionally, the height adjustment device is a scissor lift platform, and the adjustment component is set on the movable platform of the scissor lift platform.

[0023] By adopting the above technical solutions, the scissor lift platform has strong anti-overturning ability, can provide stable support for the upper components, achieve stable height adjustment, and facilitates the measurement of pipeline layout at different depths.

[0024] Optionally, a bubble level is provided on the connecting plate.

[0025] By adopting the above technical solution, the bubble level can intuitively display whether the connecting plate is in a horizontal state, assisting construction personnel to perform leveling operations more accurately and improving the accuracy of the axis layout.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The bidirectional leveling component in this application keeps the connecting plate horizontal by adjusting the extension length of the adjusting component, providing a reference surface for the pipe positioning component to adjust the emission angle of the light, realizing the positioning of multiple pipe axes at one time, and improving the positioning accuracy; 2. This application achieves the adjustment of the light angle by arranging pipe positioning components to adapt to the positioning of pipe axes on different slopes, thereby improving the versatility of the device; 3. This application improves the accuracy of the instrument by setting a communication positioning module on the rotating plate to facilitate reading the elevation of the laser emitter and ensure that the laser emitter is at the set height to emit light.

[0029] The technical solutions of various 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. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Example 1 Reference Figures 1-2 This application discloses a measuring instrument for construction pipeline layout, comprising: The bidirectional leveling component 1 includes a connecting plate 11. At least three spherical limiting grooves 12 are evenly distributed along the circumference on the lower end surface of the connecting plate 11. An adjusting member 13 is abutted in the spherical limiting groove 12. The adjusting member 13 is used to drive the connecting plate 11 to keep it horizontal. Pipe positioning component 2 is mounted on connecting plate 11 and can emit light and adjust the emission angle of the light to drive the light to simulate the axis of the pipeline. Height adjustment device 3 is used to adjust the bidirectional leveling component 1 to a set height.

[0031] Specifically, refer to Figure 1 The height adjustment device 3 is used to adjust the bidirectional leveling component 1 to a set height. The height adjustment device 3 is a scissor lift platform. The scissor lift platform can be an electric scissor lift platform with advantages such as smooth lifting and strong load-bearing capacity. The bidirectional leveling component 1 is installed on the scissor lift platform, and the bidirectional leveling component 1 is adjusted to a suitable measuring height by adjusting the height of the lift platform.

[0032] Reference Figures 1-2 The bidirectional leveling assembly 1 includes a connecting plate 11 and at least three adjusting members 13. In this embodiment, four adjusting components 13 are selected, all of which are threaded rods 131. The four threaded rods 131 are threadedly connected to the four corners of the top plate 31 of the height adjusting device 3, and the top of the threaded rod 131 has a spherical structure, specifically a ball head, the diameter of which is smaller than the diameter of the spherical limiting groove 12. The bidirectional leveling component 1 can drive the connecting plate 11 to deflect by adjusting the extension length of the threaded rods 131. The adjusting component 13 and the connecting plate 11 are connected by a floating spherical surface, so that the connecting plate 11 can rotate freely within a certain range, making it easy to keep the connecting plate 11 horizontal by adjusting the extension length of the adjusting component 13. The four threaded rods 131 can not only provide stable support for the connecting plate 11, but also realize the bidirectional leveling of the connecting plate 11 in the lateral and longitudinal directions. The threaded rods 131 can be ordinary metal threaded rods 131. The installation and adjustment of the threaded rods 131 are realized by setting an internal thread on the height adjusting device 3 that is compatible with the threaded rods 131. A bubble level 6 is provided on the connecting plate 11. The bubble level 6 adopts a bar level and is arranged in the horizontal and vertical directions of the connecting plate 11 respectively. It can intuitively display the horizontal level of the connecting plate 11 in the horizontal and vertical directions, thereby improving the accuracy of horizontal and vertical leveling of the connecting plate 11.

[0033] Reference Figures 1-3The pipe positioning assembly 2 is mounted on the connecting plate 11 and includes a rotating plate 21 and a positioning rod 22 fixed on the connecting plate 11. The positioning rod 22 is provided with a slide groove 221 and a scale 222 for marking the rotation position of the rotating plate 21. The slide groove 221 has a linear structure, and the scale 222 is a linear scale. The linear scale 222 can rotate the rotating plate 21 in the linear slide groove 221, reflecting the displacement of the rotating plate 21 in the vertical direction. The displacement of the rotating plate 21 in the vertical direction is calculated by the tilt angle given in the engineering, and then the rotating plate 21 is adjusted to the set position. After the rotating plate 21 is rotated to the set position, it can be fixed by the pin 24. In addition, the linear scale 222 is easy to manufacture and install. The linear scale 222 can be made of metal or plastic, and the scale is evenly distributed. A support rod 23 is fixed on the connecting plate 11. One end of the rotating plate 21 is hinged to the support rod 23, and the other end is slidably connected in the slide groove 221. This connection method of the rotating plate 21 allows it to rotate around the support rod 23 and slide in the groove 221, thereby adjusting the angle of the laser emitter 4 mounted on the rotating plate 21. The laser emitter 4 emits light to locate the position of the pipeline. The laser emitter 4 is generally composed of a laser diode, optical lens, etc., and can emit high-intensity, highly collimated light. For example, a red or green laser emitter 4 can be used, and its emitted light is clearly visible at the construction site. The rotating plate 21 is also equipped with a communication positioning module 5 for measuring the elevation of the laser emitter 4. The communication positioning module 5 can use a GPS module or other high-precision positioning sensors to accurately measure the elevation information of the laser emitter 4 in real time, ensuring that the laser emitter 4 is in the set position, so that the light emitted by the laser emitter 4 can more accurately simulate the pipeline axis. By rotating the rotating plate 21 and adjusting the emission angle of the laser emitter 4, combined with the elevation measurement of the communication positioning module 5, the accuracy of the pipeline axis simulation can be improved.

[0034] The implementation principle of this embodiment is as follows: The measuring instrument adjusts the bidirectional leveling component 1 to a set height using the height adjustment device 3, and then adjusts the levelness of the connecting plate 11 using the adjusting component 13 in the bidirectional leveling component 1. Next, the emission angle of the laser emitter 4 is adjusted by the rotating plate 21 in the pipeline positioning component 2, so that the emitted light can simulate the axis of the pipeline layout. At the same time, the elevation of the laser emitter 4 is measured using the communication positioning module 5, thereby improving the accuracy of the pipeline layout.

[0035] Example 2 The difference between this embodiment and the above embodiments is that: (Refer to...) Figures 4-5The adjusting component 13 adopts an electric telescopic rod 132. The fixed end of the electric telescopic rod 132 is fixed on the height adjusting device 3, and the free end is provided with a ball head 14. The ball head 14 abuts against the spherical limiting groove 12 of the connecting plate 11. The electric telescopic rod 132 is generally composed of a motor, a lead screw, a nut, etc. The motor drives the lead screw to rotate, causing the nut to move on the lead screw, thereby realizing the extension and retraction of the telescopic rod. By adjusting the extension length of different adjusting components 13, the tilt state of the connecting plate 11 is changed, and finally the connecting plate 11 reaches a horizontal state.

[0036] Reference Figures 4-6 The slide 221 adopts an arc-shaped slide 221 that is adapted to the rotation trajectory of the rotating plate 21, and the scale 222 adopts an angle scale with an arc structure; the center point of the angle scale is located at the hinge point of the rotating plate 21 and the support plate; the angle scale can directly display the angle, which not only improves the measurement efficiency, but also makes it easy for the operator to directly read the deflection angle of the connecting plate 11; the angle scale can be made of plastic or metal, and the surface is marked with clear angle scales; the bubble level 6 provided on the connecting plate 11 adopts an all-metal T-type level circular level, which can simultaneously reflect the levelness in the horizontal and vertical directions, saving layout space.

[0037] The implementation principle of this embodiment is as follows: The measuring instrument adjusts the bidirectional leveling component 1 to the set height through the height adjustment device 3, and adjusts the level of the connecting plate 11 by using the adjusting component 13 of the electric telescopic rod 132, thereby improving the automation of adjusting the connecting plate 11; the slide 221, in conjunction with the angle ruler, facilitates the direct adjustment of the rotation angle of the rotating plate 21, thereby improving the measurement efficiency; the bubble level 6 adopts an all-metal T-type level circular level, which can not only simultaneously observe the level of the rotating plate 21 in both horizontal and vertical directions, but also saves arrangement space.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of this application.
