Description

Technical Field

[0001] This utility model relates to the field of highway construction technology, specifically a slope measuring device for highway construction. Background Technology

[0002] Highways, as public roads built between cities, villages, and towns for automobiles, are an indispensable part of modern infrastructure. If the soil beneath a highway has too high a moisture content, the highway is prone to subsidence. Furthermore, highways are susceptible to depressions during long-term use or when encountering conditions exceeding their load-bearing capacity, affecting normal use. Therefore, highways frequently require construction and maintenance.

[0003] A slope measuring device for highway construction, disclosed in publication number CN215668897U, includes a base plate. A connecting rod is slidably mounted on the base plate, and a side plate is rotatably mounted on the connecting rod. A protractor is fixedly mounted on the connecting rod, with its lower edge slidably connected to the base plate. Both ends of the connecting rod are threaded with nuts, and two support blocks are vertically arranged on the outer side of the side plate. This slope measuring device for highway construction eliminates the need for calculations during the measurement process, saving time.

[0004] However, based on the working principle proposed in the aforementioned patent, the applicant believes that the device measures the slope of the road by measuring the angle between the side plate and the bottom plate. Since the bottom surface of the bottom plate needs to be completely horizontal for the measurement to accurately measure the tilt angle of the side plate, the bottom plate cannot be quickly adjusted to be horizontal when facing a road with a long slope, which leads to a reduction in measurement efficiency.

[0005] Therefore, a slope measuring device for highway construction is proposed to address the above problems. Utility Model Content

[0008] Preferably, an L-shaped support plate is fixedly installed in the middle of the inner cavity of the outer shell, and a T-shaped rod is rotatably installed through the middle of the L-shaped support plate.

[0009] Preferably, a connecting arm is fixedly installed on the surface of the T-shaped rod near the T-shaped counterweight, and a T-shaped limiting rod is fixedly installed on the connecting arm near the T-shaped counterweight, with the T-shaped limiting rod movably embedded inside the T-shaped groove.

[0010] Preferably, a T-shaped slide rail is fixedly installed on one side of the top of the L-shaped support plate, and a rack is movably installed on the top of the T-shaped slide rail, with limit plates fixedly installed at both ends of the rack.

[0011] Preferably, T-shaped connecting rods are fixedly installed on both sides of the inner cavity of the outer shell, the T-shaped connecting rods are movably embedded in the limiting plate, and a spring is sleeved on the surface of the T-shaped connecting rods and outside the limiting plate.

[0012] Preferably, a transmission gear is fixedly installed at the other end of the T-shaped rod, and the transmission gear is meshed with the rack.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses a slope measuring device for highway construction, including a housing 1. A ring frame 2 is fixedly installed on the outer side of the housing 1. An angle scale 3 is provided on the front of the ring frame 2. A transmission rod 4 is rotatably installed in the middle part of the ring frame 2. A pointer 5 is fixedly installed at the front end of the transmission rod 4 and located on the outer side of the housing 1. A T-shaped counterweight 6 is fixedly installed at the end of the transmission rod 4 and located in the inner cavity of the housing 1. A T-shaped groove 7 is provided on the back of the T-shaped counterweight 6.

[0026] Reference Figure 1 , Figure 2 , Figure 4 Through the structural design of the ring frame 2, angle markings 3, transmission rod 4, pointer 5, T, and T-shaped counterweight 6, and through the cooperation between the structures, the device achieves the function of increasing ease of use. It can use the principle of gravity to drive the pointer 5 to automatically rotate to the specified angle according to the road slope, so that the device can meet the usage requirements of different usage environments and avoid the time consumption caused by frequent adjustment steps.

[0027] An L-shaped support plate 8 is fixedly installed in the middle of the inner cavity of the outer shell 1, and a T-shaped rod 9 is rotatably installed through the middle of the L-shaped support plate 8.

[0028] Reference Figure 2 , Figure 3 , Figure 5The L-shaped support plate 8 facilitates the support and installation of components, enabling subsequent components to work in conjunction. The T-shaped rod 9 provides installation space for the transmission gear 17 and the connecting arm 10, while also transferring rotational force to the rack 13.

[0029] A connecting arm 10 is fixedly installed on the surface of the T-shaped rod 9 near the T-shaped counterweight 6. A T-shaped limiting rod 11 is fixedly installed on the connecting arm 10 near the T-shaped counterweight 6. The T-shaped limiting rod 11 is movably embedded inside the T-shaped slide groove 7.

[0030] Reference Figure 2 and Figure 4 The connecting arm 10 facilitates the connection between the T-shaped rod 9 and the T-shaped limiting rod 11, thereby facilitating subsequent transmission operations. The T-shaped limiting rod 11 is easily embedded inside the T-shaped sliding groove 7, thus working with the connecting arm 10 to constrain the T-shaped counterweight 6.

[0031] A T-shaped slide rail 12 is fixedly installed on one side of the top of the L-shaped support plate 8. A rack 13 is movably installed on the top of the T-shaped slide rail 12. Limiting plates 14 are fixedly installed at both ends of the rack 13.

[0032] Reference Figure 2 , Figure 3 , Figure 5 The T-shaped slide rail 12 facilitates the provision of a sliding track for the rack 13, thereby ensuring the stability of the rack 13 during movement. The rack 13 also facilitates the conversion of rotary motion into linear motion by engaging with the transmission gear 17.

[0033] T-shaped connecting rods 15 are fixedly installed on both sides of the inner cavity of the outer shell 1. The T-shaped connecting rods 15 are movably embedded in the limiting plate 14. A spring 16 is sleeved on the surface of the T-shaped connecting rods 15 and outside the limiting plate 14.

[0034] Reference Figure 2 and Figure 5 The T-shaped connecting rod 15 and the spring 16 work together to provide space for the rack 13 to move by utilizing its deformable characteristics. At the same time, the tension of the rack 13 is used to provide resistance to the transmission gear 17, thereby reducing the excessive and repeated swinging of the T-shaped counterweight 6 during use.

[0035] A transmission gear 17 is fixedly installed at the other end of the T-shaped rod 9, and the transmission gear 17 is meshed with the rack 13.

[0036] Reference Figure 2 and Figure 4 The transmission gear 17 facilitates meshing with the rack 13, converting the linear motion of the rack 13 into its own rotation, which in turn drives the T-shaped rod 9 to rotate, thus realizing the transmission and conversion of motion.

[0037] Working principle: When using this device, when the slope measuring device is placed on a sloping road surface, the T-shaped counterweight 6 remains vertical under the action of gravity, which drives the transmission rod 4 to rotate. The transmission rod 4 drives the pointer 5 to indicate the corresponding slope angle at the angle mark 3 of the ring frame 2. The T-shaped counterweight 6 drives the T-shaped rod 9 to rotate through the T-shaped slide 7 and the T-shaped limit rod 11. The transmission gear 17 at the other end of the T-shaped rod 9 rotates accordingly. The transmission gear 17 meshes with the rack 13, causing the rack 13 to slide on the T-shaped slide rail 12. The spring 16 will compress or stretch according to the movement of the rack 13. During this period, the tension is released by the spring 16 to gradually reduce the moving speed of the rack 13, thereby reducing the excessive swing of the T-shaped counterweight 6.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
