Description

Technical Field

[0001] This utility model relates to the technical field of engineering surveying, specifically a multi-functional level for engineering surveying. Background Technology

[0002] In engineering surveying, a level is generally used for surveying. A level is an instrument used to establish a horizontal line of sight and determine the height difference between two points on the ground. The principle is to measure the height difference between ground points based on the principle of leveling. However, the existing level used in engineering surveying still has certain defects. In the process of use, most existing level instruments are installed on tripods for measurement. Due to different ground conditions, the level needs to be adjusted multiple times after being supported by a tripod, which reduces the overall measurement efficiency.

[0003] To overcome the aforementioned deficiencies, existing technology (Chinese Patent No. CN210833506U, Publication Date: June 23, 2020) provides a multifunctional measuring device for civil engineering construction, comprising, from top to bottom, a level, a horizontal adjustment and positioning device, a data recording device, an angle measuring mechanism, and a dual-purpose adjustable support device. The angle measuring mechanism is installed at the upper end of the dual-purpose adjustable support device and is arranged parallel to the dual-purpose adjustable support device below the data recording device, thus providing vertical support for the data recording device through the dual-purpose adjustable support device. The dual-purpose adjustable support device features a novel support leg design, with a U-shaped leg between the telescopic rod and the anchor pin. The anchor pin can be folded and stored inside the U-shaped leg, allowing it to be used on complex construction sites or smooth surfaces. The data recording device facilitates the input and recording of measured data, meeting the measurement needs of various road conditions and suitable for widespread application.

[0004] While existing technologies have improved overall surveying efficiency, the leveling instrument is adjusted via a horizontal adjustment and positioning device during operation. This complex structure makes the assembly and maintenance of the device inconvenient. The horizontal adjustment and positioning device requires manual fine-tuning, which not only increases the operator's workload but also makes it difficult to guarantee the accuracy of each adjustment, thus affecting the accuracy of the measurement results.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing multi-functional level instrument for engineering surveying. Therefore, we proposed that the multi-functional level instrument for engineering surveying can effectively solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a multi-functional level for engineering surveying, in order to solve the problem mentioned in the background art that the level instruments currently set on the market are adjusted by a horizontal adjustment and positioning device, which has a relatively complex overall structure and is prone to causing inconvenience in the assembly and maintenance of the device. The horizontal adjustment and positioning device requires manual fine-tuning, which not only increases the labor intensity of the operator, but also makes it difficult to guarantee the accuracy of each adjustment by manual adjustment, thus affecting the accuracy of the measurement results.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional level for engineering surveying, comprising a level body, a storage box connected to the lower part of the level body via a lifting assembly, the lifting assembly including a motor installed inside the storage box, a rotating shaft connected to the output end of the motor, a first sleeve connected to the top end of the rotating shaft, a lifting screw threadedly connected inside the first sleeve, the top end of the lifting screw connected to the bottom of the level body, a limit block provided on the side end of the lifting screw, a guide rod penetrating through the limit block, and the guide rod located on the storage box.

[0008] Preferably, the level instrument body is provided with an observation mirror, and the level instrument body is equipped with a laser component for emitting laser light, and the first sleeve is connected through the support base.

[0009] Preferably, the storage box is provided with a conveying component, which includes an air supply component installed inside the storage box. The output end of the air supply component is connected to an air bladder through a pipe, and the air bladder is disposed on the inner wall of the storage box.

[0010] Preferably, the airbag output end is connected to a nozzle through a first pipe, the nozzle is mounted on a bracket, and the bracket spans the outside of the observation mirror.

[0011] Preferably, an eccentric wheel is provided on the outer side of the rotating shaft, and the eccentric wheel comes into contact with the airbag after rotating.

[0012] Preferably, the support base is mounted on the storage box via a buffer assembly, and a lifting rod is installed at the bottom of the support base, the lifting rod being slidably connected inside the second sleeve.

[0013] Preferably, the second sleeve is fixed inside the storage box by a support block, and the lifting rod and the outside of the second sleeve are provided with springs for cushioning.

[0014] Preferably, a U-shaped bladder is provided inside the second sleeve, the U-shaped bladder is located at the bottom of the lifting rod, and the U-shaped bladder is connected to the airbag through a second pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This multi-functional level for engineering surveying uses a lifting component to precisely adjust the height of the level body, enabling it to quickly adapt to different terrains and measurement needs. This greatly improves the efficiency of engineering surveying, reduces the inaccuracy caused by manual adjustment, and improves the accuracy of subsequent monitoring results, thus significantly increasing the efficiency of engineering surveying. The specific details are as follows:

[0016] (1) The level instrument body is precisely adjusted by the lifting component, which enables the level instrument body to quickly adapt to different terrains and measurement needs, greatly improves the work efficiency of engineering surveying, reduces the problem of poor accuracy caused by manual adjustment, improves the accuracy of subsequent monitoring results, and the level instrument body is convenient to use the observation mirror for observation, which expands the application scenarios of the level instrument body and improves the accuracy and range of measurement.

[0017] (2) The gas supply outlet delivers gas to the gas bag through a pipe, which facilitates the gas bag to deliver gas to the nozzle through the first pipe. Since the nozzle is set on the outside of the observation mirror through a bracket, it is convenient to clean the observation mirror, avoiding the influence of dust and dirt on the observation effect, ensuring that the observation mirror always maintains a clear field of view, and improving the accuracy and reliability of the measurement.

[0018] (3) The eccentric wheel on the outside of the shaft is easy to rotate. After the eccentric wheel rotates, it comes into contact with the air bag, which compresses the air bag and further enhances the pressure and frequency of gas output, which greatly improves the cleaning efficiency. This not only reduces cleaning time and labor costs, but also reduces the problem of increased overall cost caused by setting up more drive structures.

[0019] (4) The lifting rod of the buffer assembly moves up and down inside the second sleeve. The lifting rod and the spring on the outside of the second sleeve can effectively absorb and disperse external forces, reduce the damage to the level body caused by external force impact, and extend the service life of the level body.

[0020] (5) The bottom end of the lifting rod moves on the U-shaped bag, which not only further enhances the buffering effect, but also improves the stability of the level instrument body, ensuring that the level instrument body can still maintain a stable working state in complex working environments, and providing stable and reliable measurement data for engineering surveying.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: In this example, the level instrument body 1 is precisely adjusted in height by a lifting assembly, enabling it to quickly adapt to different terrains and measurement needs, thus greatly improving the efficiency of engineering surveying. Figures 1-5The technical solution shown includes a level instrument body 1, with a storage box 5 connected to the bottom of the level instrument body 1 via a lifting assembly. The lifting assembly includes a motor 6 installed inside the storage box 5, with a rotating shaft 7 connected to the output end of the motor 6. A first sleeve 8 is connected to the top of the rotating shaft 7, and a lifting screw 9 is threaded inside the first sleeve 8. The top of the lifting screw 9 is connected to the bottom of the level instrument body 1, and a limit block 10 is provided on the side of the lifting screw 9. A guide rod 11 is connected through the limit block 10 and is located on the storage box 5. The main body 1 is equipped with an observation mirror 2, and the main body 1 of the level instrument is equipped with a laser component 3 for emitting laser light. The first sleeve 8 is connected through the support base 4. The motor 6 inside the storage box 5 is opened, so that the motor 6 drives the rotating shaft 7 to rotate, which facilitates the rotation of the first sleeve 8 inside the support base 4. This causes the lifting screw 9, which is threadedly connected inside the first sleeve 8, to rotate. However, since the top of the lifting screw 9 is limited by the limit block 10 on the guide rod 11, the lifting screw 9 can easily rise at this time, allowing the top of the lifting screw 9 to rotate. The installed level instrument body 1 is height-adjustable. A lifting assembly enables precise height adjustment, allowing the level instrument body 1 to quickly adapt to different terrains and measurement needs, greatly improving the efficiency of engineering surveying. The level instrument body 1 has lifting assemblies on its bottom triangles, allowing for rapid leveling in conjunction with the internal level detector. This reduces measurement errors caused by tilting, providing reliable data support for engineering surveying and minimizing the inaccuracy issues caused by manual adjustments, thus improving the accuracy of subsequent monitoring results. The level instrument body 1 is convenient for observation using the observation mirror 2, allowing the laser element 3 on the level instrument body 1 to emit laser light. The laser element 3 can more clearly mark measurement targets in complex environments, expanding the application scenarios of the level instrument body 1 and improving measurement accuracy and range. The overall structure is simple and convenient, reducing the inconvenience of assembly and maintenance caused by complex structures and minimizing the increase in strength caused by manual adjustments, greatly improving the efficiency of engineering surveying.

[0031] Example 2: In this example, the nozzle 15 is mounted on the outside of the observation mirror 2 via the bracket 16, thus facilitating the cleaning of the observation mirror 2, preventing dust and stains from affecting the observation effect, ensuring that the observation mirror 2 always maintains a clear field of view, and improving the accuracy and reliability of the measurement. Specifically, as follows... Figures 3-6As shown, the storage box 5 is equipped with a conveying assembly, which includes a gas supply component 12 installed inside the storage box 5. The output end of the gas supply component 12 is connected to an airbag 13 via a pipe. The airbag 13 is located on the inner wall of the storage box 5. The output end of the airbag 13 is connected to a nozzle 15 via a first pipe 14. The nozzle 15 is mounted on a bracket 16, which spans the outer side of the observation mirror 2. An eccentric wheel 23 is located on the outer side of the rotating shaft 7. After the eccentric wheel 23 rotates, it contacts the airbag 13, opening the gas supply component 12 inside the storage box 5. The output end of the gas supply component 12 delivers gas to the airbag 13 via a pipe, facilitating the airbag 13's movement. 3. Gas is delivered to nozzle 15 through first pipe 14. Since nozzle 15 is set on the outside of observation mirror 2 through bracket 16, it is convenient to clean observation mirror 2, avoiding dust and stains from affecting the observation effect, ensuring that observation mirror 2 always maintains a clear field of view, and improving the accuracy and reliability of measurement. When motor 6 drives shaft 7 to rotate, eccentric wheel 23 on the outside of shaft 7 can rotate easily. After eccentric wheel 23 rotates, it comes into contact with air bag 13, causing air bag 13 to be squeezed, further enhancing the pressure and frequency of gas output, which greatly improves cleaning efficiency and reduces cleaning time and labor costs.

[0032] Example 3: In this example, the spring 21 on the outside of the lifting rod 20 and the second sleeve 19 can effectively absorb and disperse external forces, reduce the damage to the level instrument body 1 caused by external impacts, and extend the service life of the level instrument body 1. Specifically, as follows... Figures 3-7 As shown, the support base 4 is mounted on the storage box 5 via a buffer assembly. A lifting rod 20 is installed at the bottom of the support base 4, and the lifting rod 20 is slidably connected inside the second sleeve 19. The second sleeve 19 is fixed inside the storage box 5 by a support block 22. A spring 21 for buffering is provided on the outside of the lifting rod 20 and the second sleeve 19. A U-shaped bladder 18 is provided inside the second sleeve 19, located at the bottom of the lifting rod 20. The U-shaped bladder 18 is connected to the airbag 13 through the second pipe 17. When the support base 4 is subjected to external force, the support block 22 at the bottom of the support base 4 can be buffered by the buffer assembly at the upper end. At this time, the lifting rod 20 of the buffer assembly rises and falls inside the second sleeve 19, and the lifting rod 20 and the second sleeve 19... The outer spring 21 can effectively absorb and disperse external forces, reduce the damage to the level instrument body 1 caused by external impacts, and extend the service life of the level instrument body 1. Furthermore, since the air bladder 13 delivers gas to the U-shaped bladder 18 through the second pipe 17, when the lifting rod 20 moves inside the second sleeve 19, the bottom end of the lifting rod 20 moves on the U-shaped bladder 18, which not only further enhances the buffering effect but also improves the stability of the level instrument body 1. This ensures that the level instrument body 1 can maintain a stable working state even in complex working environments, providing stable and reliable measurement data for engineering surveying.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
