Abstract

This invention discloses a measuring device for architectural engineering design, comprising a base on which a storage box is mounted, and an instrument rotatably connected to the storage box; and an unfolding assembly, which includes a positioning rod disposed below and fixedly connected to the base. The positioning rod is a hollow triangular rhomboid rod with multiple sliding grooves at its top and an insertion shaft fixedly connected to its bottom. The bottom end of the insertion shaft is conical. This measuring device for architectural engineering design, through the setting of the unfolding assembly, solves the problem that the original installation process generally required manual alignment from the center groove at the top of the mounting base downwards, followed by gradual position adjustment, which was time-consuming and labor-intensive. The unfolding assembly also facilitates subsequent handling of the entire device.

Description

Technical Field

[0001] This invention relates to the field of engineering surveying technology, specifically to a measuring device for architectural engineering design. Background Technology

[0002] The construction industry is a pillar industry of the national economy and plays an important role in promoting economic development. The vast construction system requires a large number of jobs and positions, which will solve the employment problem for a large number of professionals. my country is entering a stage of accelerated urbanization. The investment growth brought about by urbanization will drive the continuous growth of demand for engineering construction services. The in-depth implementation of the new urbanization strategy will inject long-term growth momentum into construction vocational education. Construction engineering surveying serves every stage of construction engineering and runs through the entire construction project. From site leveling, building positioning, foundation construction to the installation of building components, construction surveying is required to ensure that the dimensions and positions of the building and structure meet the design requirements.

[0003] Currently, after architectural engineering designs are completed, measurement points are determined at the construction site using blueprints. A surveying instrument is then installed, and the measurements taken by the instrument are compared with the pre-made blueprints to determine the specific construction location. When using the surveying instrument, the tripod is first fixed at the measurement point, ensuring the instrument is perpendicular to the marked measurement point on the ground. Finally, the instrument is mounted on top of the tripod. However, this installation process typically requires manual alignment from the center groove at the top of the mounting base downwards, followed by gradual position adjustments, which is time-consuming and labor-intensive. Therefore, we propose a surveying device for architectural engineering design. Summary of the Invention

[0004] The purpose of this invention is to provide a measuring device for architectural engineering design to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a measuring device for architectural engineering design, comprising a base, a storage box mounted on the base, and an instrument rotatably connected to the storage box; an unfolding assembly, comprising a positioning rod disposed below and fixedly connected to the base, the positioning rod being a hollow triangular rhomboid rod with multiple sets of sliding grooves at its top end and an insertion shaft fixedly connected to its bottom end, the insertion shaft having a tapered bottom end; the unfolding assembly being disposed below the base for quickly positioning the entire device at a measuring point; and a limiting assembly, disposed in the storage box and cooperating with the unfolding assembly for limiting the free rotation of the instrument on the storage box when measurement work is stopped.

[0006] Preferably, the unfolding assembly further includes multiple sets of connecting frames disposed below and fixedly connected to the base. The multiple sets of connecting frames are distributed in a circumferential and proportional manner below the base. Each connecting frame is rotatably connected to a rotating shaft. An unfolding rod is disposed on the rotating shaft, and a half-stroke gear is fixedly connected to the rotating shaft. The multiple sets of half-stroke gears are meshed with toothed plates. The base has multiple sets of communicating grooves adapted to the toothed plates. A sliding plate adapted to the sliding groove is fixedly connected to the rear side of the toothed plate. The multiple sets of sliding plates are fixedly connected to a lifting shaft disposed inside the positioning rod. A stabilizing mechanism is disposed at the bottom end of the lifting shaft.

[0007] Preferably, the stabilizing mechanism includes multiple sets of gripping shafts disposed inside the insertion shaft. The multiple sets of gripping shafts are arranged in a circumferential shape and at equal intervals inside the insertion shaft. The insertion shaft has an inclined groove adapted to the gripping shaft. A ball is fixedly connected to the top of the gripping shaft, and a spring is sleeved on the gripping shaft and fixedly connected to the ball and the inner wall of the insertion shaft. An extension shaft is fixedly connected to the bottom of the lifting shaft. The extension shaft is located above the multiple sets of balls, and the bottom of the extension shaft is tapered.

[0008] Preferably, the limiting component includes an abutment plate disposed inside the storage box, the bottom end of the abutment plate being fixedly connected to multiple sets of tension springs fixedly connected to the base, and the top end of the abutment plate being fixedly connected to multiple sets of rubber blocks located below the instrument.

[0009] Preferably, a bubble level is installed on the base outside the storage box, which is convenient for checking whether the whole structure is tilted at any time during installation and ensuring the horizontal state during measurement.

[0010] Preferably, the bottom ends of all sets of the unfolding rods are provided with rollers, which facilitates unfolding the unfolding rods on the ground during installation.

[0011] Preferably, a rubber pad is provided at the top of the toothed plate, which helps to protect the contact plate during the process of the toothed plate being pushed into the storage box.

[0012] Preferably, the diameter of the tapered end of the extension rod is smaller than the distance between the multiple sets of spheres, which facilitates the displacement of the extension rod into the insertion shaft to compress the spheres.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention solves the problem of time-consuming and labor-intensive manual alignment from the center groove at the top of the mounting base to the bottom during the original installation process, which involved gradually adjusting the position. The restrictive component also facilitates subsequent handling. Upon reaching the measurement point, the insertion shaft at the bottom of the positioning rod is directly inserted into the marked measurement point. Then, any of the unfolding rods is unfolded, activating the unfolding component and fixing the support frame to the measurement point. The instrument is then installed. During this process, the bubble level should be constantly monitored to ensure the entire structure is level and prevent measurement errors. After measurement is stopped, the unfolding rods are retracted. The restrictive component prevents the instrument from rotating freely on the storage box during transport, saving time and effort associated with manual visual adjustments.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Please see Figure 1-8 This invention provides a technical solution: a measuring device for architectural engineering design, comprising a base 1, a storage box 2 mounted on the base 1, an instrument 3 rotatably connected to the storage box 2; an unfolding assembly 4, comprising a positioning rod 5 disposed below and fixedly connected to the base 1, the positioning rod 5 being a hollow triangular rhomboid rod, the top of the positioning rod 5 having multiple sets of sliding grooves 6, and the bottom of the positioning rod 5 being fixedly connected to an insertion shaft 7, the bottom of the insertion shaft 7 being conical; the unfolding assembly 4 being disposed below the base 1 for quickly positioning the entire device at the measuring point; and a limiting assembly 8, disposed in the storage box 2 and cooperating with the unfolding assembly 4, for limiting the free rotation of the instrument 3 on the storage box 2 when the measuring work is stopped; in addition, to facilitate easy inspection of whether the entire device is tilted during installation, a bubble level 26 is installed on the base 1 outside the storage box 2.

[0019] like Figures 5-8As shown, the unfolding assembly 4 also includes multiple sets of connecting frames 9 disposed below and fixedly connected to the base 1. The multiple sets of connecting frames 9 are distributed in a circumferential and proportional manner below the base 1. The connecting frames 9 are rotatably connected to a rotating shaft 10. An unfolding rod 11 is disposed on the rotating shaft 10 and fixedly connected to it at one end. Half-stroke gears 12 are fixedly connected to the rotating shaft 10. The multiple sets of half-stroke gears 12 are meshed with toothed plates 13. The base 1 has multiple sets of communicating grooves 14 adapted to the toothed plates 13. A sliding plate 15 adapted to the sliding groove 6 is fixedly connected to the rear side of the toothed plate 13. The multiple sets of sliding plates 15 are fixedly connected to a lifting shaft 16 disposed inside the positioning rod 5. The top of the sliding plate 15 is at the same height as the top of the lifting shaft 16, while the top of the toothed plate 13 is higher than the top of the lifting shaft 16, so that the toothed plate 13 can enter the storage box 2 through the communicating groove 14. A stabilizing mechanism 17 is disposed at the bottom of the lifting shaft 16. The stabilizing mechanism 17 includes multiple sets of connecting frames 14. The insertion shaft 7 contains multiple gripping shafts 18 arranged in a circular pattern with equal spacing. The insertion shaft 7 has inclined grooves 19 that are adapted to the gripping shafts 18. A ball 20 is fixedly connected to the top of the gripping shaft 18, and a spring 21 is fitted on the gripping shaft 18 and fixedly connected to the ball 20 and the inner wall of the insertion shaft 7. The bottom of the lifting shaft 16 is fixedly connected to an extension shaft 22, which is located above the multiple balls 20 and has a tapered bottom. To facilitate the unfolding of the unfolding rods 11 during installation, rollers 27 are provided at the bottom of each unfolding rod 11. When the toothed plate 13 moves into the storage box 2 after the measurement work stops and pushes the contact plate 23, a rubber pad is provided at the top of the toothed plate 13 for protection. In addition, to facilitate the extension rod moving into the insertion shaft 7 and squeezing the ball 20, the diameter of the tapered bottom of the extension rod is smaller than the distance between the multiple balls 20.

[0020] like Figure 3 , Figure 4 As shown, the limiting component 8 includes a contact plate 23 disposed inside the storage box 2. The bottom end of the contact plate 23 is fixedly connected to multiple sets of tension springs 24 that are fixedly connected to the base 1, and the top end of the contact plate 23 is fixedly connected to multiple sets of rubber blocks 25 located below the instrument 3.

[0021] In a specific implementation, after reaching the measurement point, the insertion shaft 7 at the bottom of the positioning rod 5 is directly inserted into the marked measurement point. Then, any one of the unfolding rods 11 is unfolded outward. The roller 27 at the bottom of the current unfolding rod 11 rolls on the ground, while the rotating shaft 10 at the top of the unfolding rod 11 rotates on the connecting frame 9 and simultaneously drives the half-stroke gear 12 to rotate. Through the meshing connection between the half-stroke gear 12 and the toothed plate 13, the half-stroke gear 12 drives the toothed plate 13 to move downward in the connecting groove 14 when it rotates. The sliding plate 15 on the rear side of the toothed plate 13 slides in the sliding groove 6, while the lifting shaft 16 moves downward in the positioning rod 5. At this time, the other toothed plate 13 is simultaneously driven to move downward, so that multiple sets of unfolding rods 11 are unfolded at the same time for support. When the lifting shaft 16 moves downward, its bottom extension shaft 22 moves downward simultaneously until the tapered end of the extension shaft 22 contacts multiple sets of balls 20. As it continues to move downward, it squeezes the multiple sets of balls 20, causing the balls 20 to drive the gripping shaft 18 to move along the inclined groove 19 to the outside of the insertion shaft 7. At the same time, the spring 21 is squeezed, and the multiple sets of gripping shafts 18 are inserted into the ground synchronously, improving the overall stability. During this process, pay attention to the bubble level 26 set on the base 1 to ensure the horizontality of the instrument 3 during measurement and improve accuracy. When the measurement work at the current measurement point is completed, it is necessary to change the measurement point. The instrument 3 will not be removed from the storage box 2. To prevent the instrument 3 from rotating freely on the storage box 2, the unfolding rod 11 is retracted. At this time, the half-stroke gear 12 drives the toothed plate 13 to move upward again. The toothed plate 13 moves to the initial position, and the top end is located inside the storage box 2 through the connecting groove 14, which contacts the bottom surface of the contact plate 23 and pushes it upward. The tension spring 24 cooperates to stretch it. The rubber block 25 at the top of the contact plate 23 contacts the bottom end of the instrument 3. The rubber block 25 increases the friction, making it difficult for the instrument 3 to rotate easily. Overall, it saves the operation and time of manual visual adjustment of the measurement.
