Description

Technical Field

[0001] This utility model relates to the field of distance measuring devices, and in particular to a wheel-type distance measuring device for engineering cost estimation. Background Technology

[0002] In the field of engineering cost estimation, accurate distance measurement is the foundation for cost accounting, quantity calculation, and construction planning. Wheeled distance measuring devices, due to their ease of operation and high measurement efficiency, have become commonly used measuring tools on construction sites, widely applied in scenarios such as road length measurement and site boundary surveying. As the scale of construction projects continues to expand and terrain conditions become increasingly complex, higher demands are placed on the measurement accuracy and stability of wheeled distance measuring devices, prompting continuous innovation and optimization of related technologies.

[0003] Existing wheel-type distance measuring devices for engineering cost estimation mainly consist of a distance measuring wheel, a transmission mechanism, and a counting and display module. The distance measuring wheel is connected to the transmission mechanism via a rotating shaft. When the distance measuring wheel rolls on the ground, it drives the rotating shaft to rotate. The transmission mechanism converts the rotation of the distance measuring wheel into a signal that can be recognized by the counting and display module. Through counting and calculation, the number of rolls is converted into the actual distance and displayed. This structure is simple and intuitive, and it achieves rapid distance measurement by combining mechanical transmission with electronic counting.

[0004] However, traditional wheeled distance measuring devices have significant drawbacks in uneven or complex terrain environments. Due to the uneven ground, the distance measuring wheel is prone to bouncing during rolling, making the contact between the wheel and the ground unstable. Once the wheel bounces, the number of rotations and the actual distance traveled are no longer precisely linearly related, causing deviations in the signal acquired by the counting and display module. Ultimately, this results in a significant decrease in measurement accuracy, making it difficult to meet the needs of accurate engineering cost measurement under complex terrain conditions. Therefore, a wheeled distance measuring device for engineering cost measurement is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a wheel-type distance measuring device for engineering cost estimation, which aims to improve the problem that traditional equipment is prone to jumping of the distance measuring wheel on uneven or complex ground, resulting in a decrease in measurement accuracy.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A wheel-type distance measuring device for engineering cost estimation includes a distance measuring wheel, a buffer assembly on the outer wall of the distance measuring wheel, a rotating shaft fixedly connected to the inner wall of the distance measuring wheel, a sensor rotatably connected to one end of the rotating shaft, a connecting rod fixedly connected to one side of the sensor, a handle fixedly connected to one end of the connecting rod, a display screen fixedly connected to the top of the handle, and a sunshade assembly provided on one side of the display screen.

[0008] The buffer assembly includes two dampers located on both sides of the measuring wheel. Two connecting rings are fixedly connected to the outer wall of the rotating shaft.

Each fixing block is rotatably connected to a transmission block, and one side of each transmission block is fixedly connected to one end of the connecting disc.

[0013] As a further description of the above technical solution:

[0014] A support block is fixedly connected to one side of the connecting frame, and the inner wall of the support block is fixedly connected to the outer wall of the connecting rod.

[0015] As a further description of the above technical solution:

[0016] The sunshade assembly includes a sunshade panel located on one side of the display screen, and a fixing shell is fixedly connected to both sides of the handle.

[0017] As a further description of the above technical solution:

[0018] The sunshade has a rotating strip fixedly connected inside, and two rotating rings are fixedly connected to the outer wall of the rotating strip. Both ends of the rotating strip are rotatably connected to the inside of the two fixed shells.

This solves the problem that when traditional equipment is in use, sunlight easily shines on the surface of the display screen, causing reflection on the surface of the display screen and making it difficult for the staff to see. This enhances the display effect of the information on the surface of the display screen. Attached Figure Description

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.

[0034] Reference Figures 1-3 An embodiment of this utility model is provided: a wheel-type distance measuring device for engineering cost estimation, including a distance measuring wheel 1, a buffer assembly provided on the outer wall of the distance measuring wheel 1, a rotating shaft 2 fixedly connected to the inner wall of the distance measuring wheel 1, a sensor 4 rotatably connected to one end of the rotating shaft 2, a connecting rod 15 fixedly connected to one side of the sensor 4, a handle 16 fixedly connected to one end of the connecting rod 15, a display screen 17 fixedly connected to the top of the handle 16, and a sunshade assembly provided on one side of the display screen 17;

[0035] The buffer assembly includes two dampers 9 located on either side of the measuring wheel 1. Two connecting rings 5 ​​are fixedly connected to the outer wall of the rotating shaft 2. These connecting rings 5, in conjunction with fixed blocks 6, transmit force, effectively transferring the jumping force of the measuring wheel 1 to the transmission block 7. Each connecting ring 5 has a fixed block 6 fixedly connected to its outer wall, supporting the transmission block 7 and enabling its rotational connection. Each fixed block 6 also has a rotatably connected transmission block 7 inside. The transmission block 7 slides in conjunction with the connecting disc 8, thus reducing the jumping force. The force is transmitted to the damper 9. Each transmission block 7 has a connecting plate 8 fixedly connected to one side. The connecting plate 8 slides on the inner wall of the protective cylinder 10 to achieve a squeezing effect on the output end of the damper 9. The output end of each damper 9 is fixedly connected to the sun visor 18. The damper 9 is used to absorb the jumping force of the measuring wheel 1 and ensure the stability of the measuring wheel 1 during rolling. The outer walls of multiple dampers 9 are provided with connecting components, including two connecting plates 11. The connecting plates 11 are used to fix the protective cylinder 10 and realize the connection between the protective cylinder 10 and the damper. The damper 9 is connected in such a way that one end of each connecting disc 11 is fixedly connected to the outer wall of the damper 9, and a protective cylinder 10 is fixedly connected to the outer wall of each connecting disc 11. The protective cylinder 10 is used to accommodate the sliding of the connecting disc 18 and restrict the movement trajectory of the connecting disc 18. Each connecting disc 18 is slidably connected to the inner wall of the protective cylinder 10. A connecting frame 3 is rotatably connected to the outer wall of the rotating shaft 2. The connecting frame 3 is used to support the fixing block 13 and achieve the fixing effect of the transmission block 12. Two fixing blocks 13 are fixedly connected to the inner wall of the connecting frame 3. The fixing blocks 13 are used for connecting... The transmission block 12 is connected to achieve the rotation effect of the transmission block 12. The transmission block 12 is rotatably connected inside each fixed block 13. The transmission block 12, together with the connecting plate 11, transmits force, achieving the effect of transmitting the reaction force of the damper 9 to the connecting frame 3. One side of each transmission block 12 is fixedly connected to one end of the connecting plate 11. One side of the connecting frame 3 is fixedly connected to a support block 14. The support block 14 is used to fix the connecting rod 15, achieving the stable support effect of the handle 16. The inner wall of the support block 14 is fixedly connected to the outer wall of the connecting rod 15.

[0036] Reference Figure 4 and Figure 5The sunshade assembly includes a sunshade 18, which blocks direct sunlight from hitting the display screen 17 and prevents glare. The sunshade 18 is located on one side of the display screen 17. Fixed housings 20 are fixedly connected to both sides of the handle 16. The fixed housings 20 accommodate the rotation of a rotating strip 19, allowing for angle adjustment of the sunshade 18. A rotating strip 19 is fixedly connected inside the sunshade 18, connecting to a rotating ring 21 to achieve rotation. Two rotating rings 21 are fixedly connected to the outer wall of the rotating strip 19, engaging with a locking strip 25 to fix the angle of the sunshade 18. Both ends of the rotating strip 19 are rotatably connected to the inside of the two fixed housings 20. A locking strip 25 is slidably connected inside one fixed housing 20, engaging with the groove inside the rotating ring 21 to lock it in place. The sun visor 18 is positioned such that one end of the locking strip 25 engages with the inside of the rotating ring 21 on one side, and the other end of the locking strip 25 is fixedly connected to a slider 23. The slider 23 is used to move the locking strip 25, thereby separating the locking strip 25 from the rotating ring 21. The slider 23 is slidably connected to the inner wall of the fixed shell 20 on one side. A push plate 22 is fixedly connected to one side of the slider 23. The push plate 22 is used to manually operate the slider 23 to adjust the angle of the sun visor 18. The push plate 22 extends through to the outside of the fixed shell 20. A spring 24 is provided inside the fixed shell 20 on one side. The spring 24 is used to push the slider 23 to reset, thereby automatically engaging the locking strip 25 with the rotating ring 21. One end of the spring 24 is fixedly connected to the outer wall of the slider 23, and the other end of the spring 24 is fixedly connected to the inner wall of the fixed shell 20 on one side.

[0037] Working principle: During the vibration damping process of the measuring wheel 1, when the measuring wheel 1 rolls on uneven or complex ground, the measuring wheel 1 is prone to jumping. This jumping force drives the fixed block 6 to move through the connecting ring 5, causing the connecting disc 8 on one side of the transmission block 7 to slide on the inner wall of the protective cylinder 10, and also squeezing the output end of the damper 9. The elasticity of the damper 9 is used to reduce the jumping force of the measuring wheel 1, ensuring that the measuring wheel 1 remains relatively stable during the rolling process. This achieves the stability of the measuring wheel 1 during the rolling process, solving the problem that the uneven or complex ground surface of traditional equipment easily causes the measuring wheel 1 to jump, resulting in a decrease in measurement accuracy, and enhancing the measurement accuracy of the equipment.

[0038] During equipment use, pulling the push plate 22 moves the slider 23, causing it to slide on the inner wall of the fixed shell 20 and compressing the spring 24. As the slider 23 moves, it causes the locking strip 25 to separate from the inside of the rotating ring 21 on one side. Next, the sunshade 18 is pushed to rotate around the rotating strip 19, blocking the light shining on the surface of the display screen 17. Then, the pulling force on the push plate 22 is released, and the rebound force of the spring 24 pushes the locking strip 25 to engage with the groove inside the rotating ring 21 on one side again, thus fixing the angle of the sunshade 18. This achieves a good sunshade effect on the display screen 17, solving the problem that sunlight easily shines on the surface of the display screen 17 during the use of traditional equipment, causing reflection on the surface of the display screen 17 and making it difficult for staff to see. This enhances the display effect of the information on the surface of the display screen 17.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
