Description

Technical Field

[0001] This utility model belongs to the field of road testing instruments, and in particular relates to a road slope mapping and testing instrument that adapts to terrain. Background Technology

[0002] Road slope surveying instruments are specialized devices used to measure and assess the inclination of road surfaces. These instruments are crucial for ensuring road safety, the effectiveness of drainage systems, and the smoothness of vehicle travel. They are commonly used in civil engineering and traffic engineering fields for topographic surveying, road construction quality control, and road maintenance.

[0003] However, traditional road slope surveying instruments have certain design limitations, especially when facing complex terrains such as ditches and rugged mountains, where their adaptability and flexibility are significantly insufficient. Due to their fixed structure, traditional equipment is difficult to adjust to different terrain conditions, making stable placement challenging in complex environments. This instability not only easily causes the instrument to tilt or shake, but also seriously affects the accuracy and reliability of the measurement results, failing to meet the needs of diverse measurement scenarios.

[0004] Therefore, it is necessary to design a road slope mapping and detection instrument that adapts to terrain in order to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of traditional road slope surveying and testing instruments, such as rigid structure, poor adaptability, and difficulty in stable measurement in complex terrain, which affects the measurement accuracy and reliability of the measurement results, this utility model provides a road slope surveying and testing instrument that is adaptive to terrain.

[0006] This utility model is achieved through the following technical means: an adaptive terrain road slope mapping and detection instrument, comprising a handle, a detection support frame, a rotating ring, a rotating shaft, a detection ball, a counterweight, a mapping marking line, a measuring line, a support plate, magnets, and a support assembly. The detection support frame is fixedly connected to one end of the handle. The rotating ring is rotatably disposed inside the detection support frame. The rotating shaft is rotatably disposed in the middle position of the rotating ring. The detection ball is installed outside the rotating shaft, and its spherical surface forms rotational contact with the inner wall of the detection support frame. The counterweight is installed in the lower inner part of the detection ball and maintains an appropriate distance from the inner wall of the detection support frame. A mapping marking line is printed on the surface of the detection ball, and the mapping marking line surrounds the surface of the detection ball in the longitudinal direction. A measuring line is printed on one side of the detection support frame, and the measuring line extends in the transverse direction and intersects with the mapping marking line. Two support plates are arranged opposite each other and rotatably connected to the other end of the handle. The two support plates are completely embedded in the handle. Each support plate is fixedly connected with multiple magnets distributed along its height direction, and the magnets are completely embedded in the support plate. The support assembly is located at the other end of the handle.

[0007] In one embodiment, the support assembly includes a connecting rod, a pin, a connecting cylinder, a retaining bead, a spring, a support rod, and a hinge rod. The other end of the handle is slidably inserted with the pin. The connecting rod is fixed to the bottom end of the pin. The diameter of the top end of the connecting rod is consistent with the diameter of the bottom end of the handle. The connecting cylinder is slidably disposed at one end of the connecting rod. A retaining bead is slidably disposed in the upper part of the connecting cylinder. The spring is fixed between the retaining bead and the connecting cylinder. One side of one end of the connecting rod has multiple vertically spaced retaining holes. The retaining bead is inserted into the first retaining hole from the top. Multiple support rods are rotatably disposed on the connecting cylinder and evenly distributed along its center. A hinge rod is rotatably disposed between the fixed end of each support rod and the other end of the connecting rod.

[0008] In one embodiment, the handle surface is provided with anti-slip texture.

[0009] In one embodiment, one end of the pin has a tapered structure.

[0010] In one embodiment, the area where the connecting cylinder and the connecting rod slide in contact is provided with an anti-slip coating.

[0011] In one embodiment, the support rod is a telescopic adjustable rod.

[0012] Beneficial effects: 1. By setting an adjustable support component, its length can be flexibly adjusted according to the actual ground conditions. This design allows the instrument to be placed stably whether facing flat roads or rugged terrain by adjusting the length of the support rod, thereby effectively avoiding the instrument tilting or swaying due to complex terrain;

[0013] 2. When removing the handle, the support plate can be rotated 90 degrees to create an additional support structure at the bottom of the handle, making it particularly suitable for surveying in special terrains such as ditches. Furthermore, using magnets fixed to the support plate, the handle can be stably placed on railings or other metal objects, further increasing its stability under various terrain conditions.

[0014] 2. During height adjustment, the connecting rod and connecting cylinder are fixed in relative position through the cooperation of locking holes, locking balls, and springs. When the connecting rod is moved slowly to adjust the height, the locking balls will engage with the corresponding locking holes under the action of the spring, ensuring that the relative position between the connecting rod and the connecting cylinder remains unchanged, thus guaranteeing the stability and accuracy of the height adjustment operation.

Detailed Implementation

[0023] Example: A road slope mapping and detection instrument that adapts to terrain, such as Figures 1-7As shown, the device includes a handle 1, a detection support frame 2, a rotating ring 3, a rotating shaft 4, a detection ball 5, a counterweight 6, surveying marking lines 7, measurement lines 8, a support plate 9, a magnet 10, and a support assembly. The detection support frame 2 is welded to the upper end of the handle 1. The rotating ring 3 is rotatably positioned inside the detection support frame 2. The rotating shaft 4 is rotatably positioned in the middle of the rotating ring 3. The detection ball 5 is bolted to the outside of the rotating shaft 4, and its spherical surface forms rotational contact with the inner wall of the detection support frame 2. The counterweight 6 is bolted to the lower inner part of the detection ball 5, maintaining an appropriate distance from the inner wall of the detection support frame 2 to ensure the detection ball 5 can rotate normally. A surveying marking line 7 is printed on the surface of the detection ball 5, encircling the surface of the detection ball 5 in the longitudinal direction. A measurement line 8 is printed on the front side of the detection support frame 2, extending in the transverse direction and intersecting with the surveying marking line 7. The relative positions of the two components allow for relevant measurements. The two support plates 9 are positioned opposite each other and rotatably connected to the lower end of the handle 1. The two support plates 9 are completely embedded in the handle 1, so they do not affect the overall appearance and operation of the handle 1 when not in use. Furthermore, a damping structure (metal friction plate) is provided at the connection between the support plate 9 and the handle 1. When the support plate 9 rotates to 90°, due to the friction between the materials being greater than the rotational tendency caused by external force, the support plate 9 can maintain its set position without external disturbance, thus achieving lock-free operation. To retract or unfold it again, a certain force needs to be applied to overcome the friction before it can rotate. Each support plate 9 has three magnets 10 bonded to it, distributed along its height, and the magnets 10 are completely embedded in the support plate 9, which ensures the stability of the magnets 10 without increasing the extra thickness of the support plate 9. The support assembly is located at the lower end of the handle 1.

[0024] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the support assembly includes a connecting rod 11, a pin 12, a connecting cylinder 13, a retaining ball 15, a spring 16, a support rod 17, and a hinge rod 18. The pin 12 is slidably inserted into the lower end of the handle 1. The upper end of the pin 12 has a tapered structure to ensure that when inserted into the handle 1, the upper end can smoothly pre-enter the handle 1, avoiding jamming or excessive resistance and ensuring smooth operation. The connecting rod 11 is welded to the bottom end of the pin 12. The diameter of the top end of the connecting rod 11 is consistent with the diameter of the bottom end of the handle 1. In the initial state, the top end of the connecting rod 11 contacts the bottom end of the handle 1, indicating that the pin 12 has been inserted correctly. The connecting cylinder 13 is slidably positioned above the connecting rod 11. The area where the connecting cylinder 13 slides in contact with the connecting rod 11 is coated with an anti-slip coating, which effectively increases the slip resistance between the connecting rod 11 and the connecting cylinder 13. Friction prevents the connecting rod 11 from sliding freely when adjusting the height, ensuring stable height adjustment operation. A retaining bead 15 is slidably installed in the upper part of the connecting cylinder 13. A spring 16 is welded between the retaining bead 15 and the connecting cylinder 13 to provide a reset force for the retaining bead 15. Multiple vertically spaced retaining holes 14 are opened on the front side of the upper end of the connecting rod 11. When the retaining bead 15 is inserted into the first retaining hole 14 from the top, it proves that the connecting rod 11 is in the lowest position. Three support rods 17 are rotatably installed on the connecting cylinder 13 and evenly distributed along its center. The support rods 17 are telescopic adjustable rods, and their length can be flexibly adjusted according to the actual ground conditions to ensure stable placement of the instrument. A hinge rod 18 is rotatably installed between the fixed end of each support rod 17 and the lower end of the connecting rod 11.

[0025] When it is necessary to use the instrument to measure the road slope, the operator first carries the instrument to the location to be measured, places the instrument on the ground, and then pulls the connecting rod 11 upward to adjust the height of the handle 1 according to the actual measurement needs, so as to ensure that the detection ball 5 is at a suitable height position for subsequent accurate measurement.

[0026] During the adjustment of the height of the connecting rod 11, the connecting rod 11 interacts with the retaining bead 15, squeezing the retaining bead 15 so that it slides into the connecting cylinder 13 and disengages from the current retaining hole 14. At the same time, the retaining bead 15 squeezes the spring 16, causing it to compress and deform. Since the connecting rod 11 and the support rod 17 are connected by the hinge rod 18, when the connecting rod 11 moves upward, the support rod 17 is driven to rotate outward and unfold through the hinge rod 18. As the support rod 17 unfolds, it contacts the ground, forming a stable support structure, providing reliable support for the instrument and preventing the instrument from shaking due to uneven ground or external interference during the measurement process.

[0027] When the connecting rod 11 is adjusted to the appropriate height, the pulling action is stopped. At this time, the spring 16 quickly returns to its original state, and the elastic force pushes the locking ball 15 out of the connecting cylinder 13 and into the corresponding locking hole 14, thereby fixing the relative position between the connecting rod 11 and the connecting cylinder 13, ensuring that the instrument is height stable during the measurement process and will not change arbitrarily due to external forces.

[0028] When the instrument is placed on ground with different slopes, the detection ball 5 rotates freely within the detection support frame 2 under the influence of its own weight and the counterweight 6 until it reaches a balanced state that adapts to the slope of the ground. At this time, there is a relative offset between the longitudinal surveying mark line 7 on the surface of the detection ball 5 and the transverse measuring line 8 set on the front side of the detection support frame 2. By observing the angle difference between the two and combining it with the scale value on the measuring line 8, the operator can quickly determine and calculate the tilt angle of the current terrain, i.e., the road slope.

[0029] When taking measurements in ditches or other special terrain environments, the handle 1 can be removed from the connecting rod 11, and then the support plate 9 can be rotated downwards to 90 degrees. At this time, the support plate 9 forms a support structure at the lower end of the handle 1, increasing the contact area between the handle 1 and the ground and improving the stability of the handle 1. Then, the handle 1 can be placed in ditches or other special terrains to carry out the corresponding measurement work.

[0030] Meanwhile, by using the magnet 10 fixed on the support plate 9, the handle 1 can be stably placed on a guardrail or an object made of iron or other materials. When the handle 1 is close to these objects, the magnet 10 generates a magnetic force, which attracts the handle 1 to the surface of the object, further ensuring the stability of the handle 1 during the measurement process, thereby adapting to the measurement needs of different terrains.
