Utility Model Content

[0005] In order to improve the problem of uneven ground that may affect measurement errors, the present application provides a slope ruler body for highway engineering.

[0006] The present application provides a slope gauge for highway engineering, which adopts the following technical solution:

[0008] By adopting the above technical solution, when measuring the slope, the uneven ground is flattened front and back by using the push plate of the handheld slope ruler body, and the flattened ground is compacted by the pressure wheel. Then, the flatness of the measured surface meets the measurement requirements, and the slope ruler body is placed against the measured surface for detection. The operation is simple and the measurement accuracy is high.

By utilizing the elastic force of the spring, the two locking blocks automatically slide towards each other until they abut against each other, thereby effectively locking the rotating shaft, making it rotate and stably connected in the slot for use, with a reliable structure and easy assembly and disassembly.

DETAILED DESCRIPTION

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] The present application embodiment discloses a slope ruler for highway engineering, referring to Figure 1 and Figure 2 , including a slope ruler body 1. In this embodiment, in order to improve the measurement accuracy of the slope ruler body 1 so that the slope ruler body 1 can accurately measure the slope when surveying on an uneven ground, push plates 2 are detachably connected at the front and rear ends of the slope ruler body 1 near the bottom, and a rolling groove 3 is also provided at the bottom of the slope ruler body 1 between the two push plates 2. The length extension direction of the rolling groove 3 is consistent with the length extension direction of the slope ruler body 1, and the notch of the rolling groove 3 faces the ground, and a pressure wheel 30 is rotatably connected to the inner wall of the rolling groove 3.

[0033] When in use, the construction worker pushes the slope ruler body 1 back and forth by holding the slope ruler body 1, and then the push plate 2 flattens the raised surface, and the pressure wheel 30 then compacts the pushed ground, so that the flatness of the measured surface is higher. Finally, the slope ruler body 1 is fixed on the measured surface for detection, which effectively reduces the measurement error and is easy to operate. In order to make it easier for the push plate 2 to flatten the raised part when in use, the cross-section of the push plate 2 is also set to a cone, and the tips of the two push plates 2 are away from the slope ruler body 1, so that when the push plate 2 is in use, the tip part quickly flattens the protrusion, and soil and other debris are pushed away from the inclined surfaces on both sides, which saves time and effort and is highly practical.

[0034] Reference Figure 2The cam 40 is provided with a screw thread 44 which is adapted to the position of the lever 4 and the lever 4 is provided with a screw thread 45 which is adapted to the position of the lever 4. The cam 40 is provided with a screw thread 45 which is adapted to the position of the lever 4 and the lever 4 is provided with a screw thread 46 which is adapted to the position of the lever 4. The cam 40 is provided with a screw thread 44 which is adapted to the position of the lever 4 and the lever 4 is provided with a screw thread 46 which is adapted to the position of the lever 4.

[0035] In order to avoid the locking nut 6 interfering with the detection, the through holes 50 on both sides of the slope ruler body 1 are set as countersunk holes, and the locking nuts 6 are connected in the countersunk holes, which can also improve the aesthetics of the slope ruler body 1. When the push plate 2 needs to be disassembled, the locking nuts 6 are removed from both ends of the locking rod 5, the locking rod 5 is pulled out, and then the rod 4 is taken out from the socket 40, which is convenient for assembly and disassembly.

[0036] Reference Figure 2 In this embodiment, in order to increase the compaction effect of the pressure wheel 30 on the ground, a plurality of pressure wheels 30 are rotatably connected to the inner wall of the rolling groove 3 along its length extension direction, and a rotation gap is left between adjacent pressure wheels 30, and the pressure wheel 30 is rotatably connected to the inner wall of the rolling groove 3 through the rotating shaft 7. A slot 8 adapted to the rotating shaft 7 is provided on the inner wall of the rolling groove 3. The inner wall of the slot 8 is arranged in an arc shape so that the rotating shaft 7 can be clamped in the slot 8 for rotation, and the top of the slot 8 is arranged in an open shape. During installation, the rotating shaft 7 is connected to the slot 8 from the top of the slot 8, and then a locking piece for locking the rotating shaft 7 in the slot 8 is provided on the inner wall of the slot 8. The locking piece effectively reduces the possibility of the rotating shaft 7 falling off from the slot 8.

[0037] Reference Figure 3 and Figure 4 In this embodiment, the locking member includes a locking block 80 slidably connected to the two side walls of the slot 8, and a receiving groove 81 is provided on the inner walls of the two sides of the slot 8. A spring 82 in a stretched state is connected between the inner wall of the receiving groove 81 and the locking block 80. The spring 82 makes the two locking blocks 80 tend to slide towards each other, and then after the rotating shaft 7 is engaged in the slot 8, the sliding locking blocks 80 abut against each other, effectively connecting the rotating shaft 7 in the slot 8 so that the pressure wheel 30 rotates stably.

[0038] In addition, during the use of the pressure wheels 30, clay, stones and other debris may be embedded in the rotation gap between adjacent pressure wheels 30, thereby affecting the rotation of the pressure wheels 30. Therefore, a driving member for driving the two locking blocks 80 to slide away from each other is also provided on the slope ruler body 1, including a push rod 9. A slide groove 90 is opened on the inner wall of the accommodating groove 81. The length extension direction of the slide groove 90 is perpendicular to the length extension direction of the accommodating groove 81, and the notch of the slide groove 90 faces the ground. One end of the push rod 9 is fixedly connected to the locking block 80, and the other end passes through the notch of the slide groove 90.

[0039] When in use, by pushing the push rod 9 on the two locking blocks 80, the push rod 9 slides in the slide groove 90, effectively driving the two locking blocks 80 away from each other, and the spring 82 changes from a stretched state to a compressed state, and then the rotating shaft 7 can be taken out from the slot 8, which is convenient for cleaning the embedded debris. After cleaning, the two locking blocks 80 are driven to slide away, and after the rotating shaft 7 is connected to the slot 8, the elastic force of the spring 82 is used to drive the two locking blocks 80 to slide close to each other, and then the rotating shaft 7 is locked, which is convenient for assembly and disassembly.

[0040] The implementation principle of a slope ruler for highway engineering in the embodiment of the present application is as follows: when the slope ruler body 1 is measured on an uneven ground, the raised ground is flattened by the front and rear push plates 2, and the pressure wheel 30 compacts the flattened ground, effectively improving the flatness of the measured surface, thereby improving the measurement accuracy. Furthermore, if there are debris adhered to the push plate 2, the push plate 2 can be removed and cleaned. Similarly, if there are debris embedded between the pressure wheels 30, the pressure wheels 30 can also be removed and cleaned by disassembly and assembly.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
