Description

Technical Field

[0001] This utility model relates to the technical field of testing equipment, and in particular to a highway slope testing device. Background Technology

[0002] Currently, roadbed slopes are often generated during road construction due to high excavation or filling. Depending on the soil conditions of each slope section, different slope ratios are usually designed. During construction, in order to ensure the slope gradient, it is necessary to use a measuring ruler to measure the slope multiple times.

[0003] Chinese utility model patent, publication number CN211954122U, discloses a slope inspection ruler for highway subgrade construction. It describes a method where the main ruler is placed against the horizontal surface of the slope, and the secondary ruler is flipped to align with the slope's incline. The secondary ruler drives a pin to rotate synchronously, and the pin rotates synchronously with the spindle via a transmission assembly. The spindle then drives the scale cylinder to rotate, aligning the indicator needle with the corresponding degree on the scale cylinder, thus accurately measuring the slope's degree. However, slopes at the same cross-section often differ, and when slope inspection is required at various locations along the same cross-section, the main ruler of this patent cannot effectively locate a horizontal surface. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a highway slope detection device.

[0005] The present invention provides the following technical solution: a highway slope detection device, comprising a main ruler, a support component disposed on the main ruler, and a secondary ruler component disposed on the main ruler, wherein the secondary ruler component is fitted with the slope, thereby forming an angle with the main ruler, thereby detecting the slope gradient;

[0006] The main ruler has a storage groove on its inner side and a limiting hole on its main ruler. The limiting hole is connected to the storage groove and is perpendicular to it.

[0007] The support assembly includes a support member, several grooves formed on the support member, several guide blocks disposed at the receiving slot, the guide blocks being located within the grooves, and a fastener for restricting the vertical movement of the support member.

[0008] Furthermore, the auxiliary ruler assembly includes a rotating seat disposed on the main ruler, a rotating shaft rotatably connected to the rotating seat, and an auxiliary ruler body disposed on the rotating shaft, the auxiliary ruler body being in contact with the slope.

[0009] Furthermore, the auxiliary scale assembly also includes a pointer disposed on the rotating shaft and an arc-shaped angle scale disposed on the main scale, the angle scale being coaxial with the rotating shaft.

[0010] Furthermore, the fastener is a locking bolt, which is threadedly connected to the main scale. When the support passes through the limiting hole, the locking bolt abuts against one side of the support, thereby restricting the support.

[0011] Furthermore, a level is provided on the main scale, and the level is arranged parallel to the main scale.

[0012] Furthermore, the highway slope detection device also includes a rotating component rotatably connected to the main ruler. When the support component is completely located in the receiving groove, the support component is limited to the receiving groove by rotating the rotating component to the bottom of the receiving groove.

[0013] Furthermore, the highway slope detection device also includes a locking assembly for limiting the rotation of the rotating shaft. The locking assembly includes a sliding sleeve disposed on the main ruler, a contact member slidably connected in the sliding groove, and a driving member for driving the contact member to move. The contact member abuts against the outer wall of the rotating shaft, thereby limiting the rotation of the rotating shaft.

[0014] Furthermore, the contact element includes a slider that is slidably connected within the sliding sleeve, and a second friction element disposed at the end of the slider, the second friction element cooperating with the rotating shaft.

[0015] Furthermore, the driving component is a push bolt, which is rotatably connected to the sliding sleeve and threadedly connected to the slider.

[0016] Furthermore, a first friction element is sleeved on the outer wall of the rotating shaft, and the first friction element and the second friction element are in frictional engagement, thereby restricting the rotation of the rotating shaft.

[0017] The beneficial effects of this utility model are as follows: By inserting the support member into the limiting hole and then adjusting the support member to support the main ruler, the main ruler is adjusted to a horizontal state by observing the level. Then, the locking bolt is rotated so that the locking screw abuts against the support member to ensure that the support member does not slide up and down. After adjusting the main ruler to be horizontal, the operator rotates the main body of the auxiliary ruler so that the main body of the auxiliary ruler fits against the slope. By observing the angle mark on the angle ruler pointed to by the pointer, the angle of the slope at other positions can be obtained. Thus, it is also convenient for the main ruler to find the horizontal plane on inclined slopes. Attached Figure Description

[0029] Example 1

[0030] This embodiment provides a highway slope detection device, which can be referenced. Figures 1-6 It includes a main ruler 1, a support component 2 set on the main ruler 1, and a secondary ruler component 3 set on the main ruler 1. The secondary ruler component 3 is attached to the slope 7, thereby forming an angle with the main ruler 1, so as to detect the slope of the slope 7.

[0031] Among them, you can refer to Figure 3 The main ruler 1 is long and narrow, with a storage groove 11 on the inner side, and a limiting hole 12 on the main ruler 1. The limiting hole 12 is connected to the storage groove 11 and is perpendicular to each other.

[0032] For reference Figure 4 and Figure 5 The support component 2 includes a long strip-shaped support member 21 with two grooves 22 on its surface. The two grooves 22 are located on both sides of the support member 21 and are in a straight line shape. Two guide blocks 23 are provided at the receiving groove 11 and are located in the two grooves 22 respectively. Of course, in other embodiments, the number of grooves 22 can be increased or decreased as needed. A locking bolt 24 is threadedly connected to the main scale 1. When the support member 21 passes through the limiting hole, the locking bolt 24 abuts against one side of the support member 21, thereby restricting the up and down movement of the support member 21.

[0033] For reference Figure 6 The auxiliary ruler assembly 3 includes a rotating seat 31 mounted on the main ruler 1, a rotating shaft 32 rotatably connected to the rotating seat 31, and a long strip-shaped auxiliary ruler body 33 mounted on the rotating shaft 32. The auxiliary ruler body 33 is in contact with the slope 7, thereby forming an angle between the auxiliary ruler body 33 and the main ruler 1 to measure the slope of the slope 7. Furthermore, the auxiliary ruler assembly 3 also includes a pointer 34 mounted on the rotating shaft 32 and an arc-shaped angle ruler 35 mounted on the main ruler 1. The angle ruler 35 and the rotating shaft 32 are on the same axis. When the rotating shaft 32 rotates, the pointer 34 also rotates. When the auxiliary ruler body 33 is in contact with the slope 7, the pointer 34 points to the degree of the angle ruler 35, which is the slope of the slope 7.

[0034] Furthermore, a level 6 is provided on the main ruler 1. The level 6 is set parallel to the main ruler 1. The level 6 allows the main ruler 1 to find the horizontal surface more quickly. The level 6 can be a bubble level. The main ruler 1 can be judged to be horizontal by observing whether the bubble is in the middle of the level. The level 6 is existing technology and will not be described in detail here.

[0035] In summary, when the operator needs to check the slope of slope 7, first, the main ruler 1 can be brought into contact with the roadbed. Then, the main body 33 of the auxiliary ruler is rotated until it is in contact with slope 7. The angle of slope 7 can then be obtained by observing the angle mark on the angle ruler 35 indicated by the pointer 34. When the operator needs to check the slope at other locations on slope 7, such as... Figure 1 As shown, since slope 7 is inclined, it is difficult to find the horizontal plane of the main ruler 1 when it is necessary to detect the slope angle of slope 7. Therefore, the operator can rotate the support 21 downwards, rotate it out of the storage groove 11, and rotate it until it is perpendicular to the storage groove 11. Then, the support 21 is inserted into the limiting hole. The size of the limiting hole is adapted to the size of the support 21, thereby limiting the swing of the support 21. Then, the operator can adjust the support 21 and observe the level 6 to adjust the main ruler 1 to a horizontal state. Then, rotate the locking bolt 24 so that the locking screw abuts against the support 21 to ensure that the support 21 does not slide up and down. After adjusting the main ruler 1 to be horizontal, the operator rotates the main body 33 of the auxiliary ruler to make The main body 33 of the auxiliary ruler is in contact with the slope 7. The rotation of the main body 33 of the auxiliary ruler drives the rotating shaft 32 to rotate, and the rotation of the rotating shaft 32 drives the pointer 34 to rotate. When the main body 33 of the auxiliary ruler rotates and is in contact with the slope 7, the angle of the slope 7 at other positions can be obtained by observing the angle mark of the angle ruler 35 pointed to by the pointer 34. When it is necessary to store the detection device, the operator can loosen the locking bolt 24 so that the locking bolt 24 no longer abuts against the support member 21. Then, when the sliding support member 21 moves downward to the limit position, the support member 21 moves out of the limiting hole 12. Then, the support member 21 is rotated to store it into the storage groove 11. Then, the auxiliary ruler main body 33 is rotated to contact the main ruler 1, and the storage of the detection device is completed.

[0036] In summary,

[0037] Example 2

[0038] For reference Figure 2 This embodiment further includes, based on the first embodiment, a rotating component 5 that is rotatably connected to the main scale 1;

[0039] It is understood that when the support member 21 is completely inside the storage groove 11, the support member 21 is limited inside the storage groove 11 by rotating the rotating member 5 to the bottom of the storage groove 11; when it is necessary to remove the support member 21 from the storage groove 11, the rotating member 5 is rotated away from the bottom of the storage groove 11, and the support member 21 can be removed from the storage groove 11.

[0040] Example 3

[0041] For reference Figure 7This embodiment further includes, based on the first or second embodiment, a locking component 4 for limiting the rotation of the rotating shaft 32. The locking component 4 includes a sliding sleeve 42 provided on the main scale 1, a contact member slidably connected in the sliding groove, and a driving member for driving the contact member to move. The contact member abuts against the outer wall of the rotating shaft 32, thereby limiting the rotation of the rotating shaft 32.

[0042] The contact element includes a slider 43 that is slidably connected within the sliding sleeve 42, and an arc-shaped second friction element 45 disposed at the end of the slider 43, the second friction element 45 cooperating with the rotating shaft 32.

[0043] Furthermore, the driving component is a push bolt 44, which is rotatably connected to the sliding sleeve 42 and threadedly connected to the slider 43;

[0044] Furthermore, a first friction element 41 is sleeved on the outer wall of the rotating shaft 32, and the first friction element 41 and the second friction element 45 are in frictional engagement, thereby restricting the rotation of the rotating shaft 32;

[0045] It is understandable that the operator can rotate and push the bolt 44, which in turn drives the slider 43 to move closer to the rotating shaft 32. The slider 43 drives the second friction element 45 to abut against the outer wall of the first friction element 41. Thus, through the frictional engagement between the first friction element 41 and the second friction element 45, the rotation of the rotating shaft 32 can be restricted, making it difficult for the main body 33 of the auxiliary scale to rotate. In other words, when the detection device is stored away, the main body 33 of the auxiliary scale can be effectively prevented from opening by its own weight. When it is necessary to rotate the main body 33 of the auxiliary scale, it is only necessary to rotate and push the bolt 44 to make the first friction element 41 and the second friction element 45 no longer in contact.
