Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of distance measuring devices, in particular to a distance measuring device for highway engineering. Background Art
[0002] Distance measurement is one of the most basic tasks in highway engineering surveying. It mainly refers to measuring the length of the line connecting two points on the ground. What usually needs to be measured is the horizontal distance, that is, the length of the projection of the line connecting the two points on a certain horizontal plane. It is one of the elements to determine the plane position of the ground point.
[0003] Some existing highway engineering distance measuring devices are usually equipped with brackets when in use. Such highway engineering distance measuring devices usually need to open the support legs in sequence and then fix the opening and closing angles. However, when on a relatively flat road surface, the process of opening the support legs in sequence and then fixing the angles is rather cumbersome. In addition, if the opening and closing angles of the support legs are different, the highway engineering distance measuring device will also be tilted, which will result in a long preparation time and low practicality. In view of this, we propose a highway engineering distance measuring device to solve the above problems. Utility Model Content

[0016] Beneficial effects:
[0017] 1. The highway engineering distance measuring device can realize the simultaneous opening and closing of the supporting legs on both sides by the staff rotating the active worm gear, thus solving the problem that the supporting legs of some existing highway engineering distance measuring devices are inconvenient to adjust. The staff does not need to adjust the supporting legs on both sides separately, thus saving the staff time for preparation work before distance measuring. Meanwhile, the opening and closing angles of the supporting legs on both sides are ensured to be the same, thus avoiding the situation that the distance measuring device body tilts due to different opening and closing angles on both sides. Meanwhile, the stability of the supporting legs is also ensured by the arrangement of the first worm gear, the active worm gear and the driven worm gear.
[0018] 2. The highway engineering distance measuring device drives the rotation of the second worm gear by rotating the adjusting worm, and finally realizes the adjustment of one side support leg, which improves the flexibility of the device in actual use. When the device is used on an inclined road surface, the level of the distance measuring device body can be ensured by adjusting the opening and closing angle of one side support leg separately, which is convenient for the staff to choose overall adjustment or separate adjustment according to the actual use environment, and the operation is simple.
[0019] 3. The highway engineering distance measuring device drives the second bevel gear to rotate by the staff rotating the driving rod, and finally drives the fixed cone to move by the movement of the guide plate, thereby improving the functionality of the device. When using the device on a cement road surface, the staff can increase the contact area between the device and the ground by making the two supporting legs contact the ground, thereby improving the stability of the device when placed. When used on soft land, the staff can make the fixed cone drop out of the second groove, so that the fixed cone penetrates into the land, thereby improving the placement stability of the device, further improving the practicality of the device, and facilitating the staff to flexibly adjust the placement method of the device according to the use environment.

DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] See also Figure 1-Figure 5 The utility model provides a technical solution: a highway engineering distance measuring device, including a distance measuring device body 1, a mounting plate 2 is arranged on the lower side of the distance measuring device body 1, the interior of the mounting plate 2 is hollow, and the surfaces of both sides of the mounting plate 2 are provided with first grooves 3 extending from the lower surface, a connecting plate 4 is arranged inside the first groove 3, a first rotating shaft 5 is sleeved inside the connecting plate 4, both ends of the first rotating shaft 5 are rotated to pass through the connecting plate 4, both ends of the first rotating shaft 5 are rotated to pass through the interior of the mounting plate 2, and the front ends of the two first rotating shafts 5 are sleeved with first worm gears 8. An active worm 9 is arranged outside the mounting plate 2. The left end of the active worm 9 rotates and penetrates into the interior of the mounting plate 2. One end of the active worm 9 located inside the mounting plate 2 is fixedly connected with a driven worm 10. The active worm 9 and the driven worm 10 are respectively meshed with the two first worm wheels 8. The patterns of the surfaces of the active worm 9 and the driven worm 10 are opposite to those of the meshing of the first worm wheels 8. Two fixed plates 6 are fixedly connected to the lower surface of the connecting plate 4. A supporting leg 7 is arranged between the two fixed plates 6. When the staff rotates the active worm 9, the active worm 9 is rotated by the active worm 9. The rotation of the active worm 9 will drive the rotation of the driven worm 10, and then drive the rotation of the two first worm wheels 8. Because the lines arranged on the surfaces of the active worm 9 and the driven worm 10 are opposite to those meshing with the first worm wheels 8, the rotation of the active worm 9 and the driven worm 10 will cause the two first worm wheels 8 to rotate in the opposite direction. The rotation of the two first worm wheels 8 drives the rotation of the first rotating shaft 5, and the rotation of the first rotating shaft 5 drives the connecting plate 4 to rotate inside the first groove 3. The rotation of the connecting plate 4 drives the rotation of the fixed plate 6, and then drives the rotation of the supporting legs 7, and finally realizes the simultaneous opening and closing of the supporting legs 7 on both sides. The above device solves the problem that the supporting legs of some existing highway engineering distance measuring devices are not easy to adjust. There is no need for the staff to adjust the supporting legs 7 on both sides separately, which saves the staff time for the preparation work before the distance measuring work. At the same time, it also ensures that the opening and closing angles of the supporting legs 7 on both sides are the same, avoiding the situation that the distance measuring device body 1 is tilted due to the different opening and closing angles on both sides. At the same time, the stability of the supporting legs 7 is also guaranteed by the arrangement of the first worm wheel 8, the active worm 9 and the driven worm 10.
[0028] Furthermore, a cavity 11 is provided inside the rear fixing plate 6, and a second rotating shaft 12 is rotatably connected between the two fixing plates 6. Both ends of the second rotating shaft 12 are rotatably inserted into the fixing plate 6, and one end of the second rotating shaft 12 located inside the cavity 11 is sleeved with a second worm gear 13, and an adjusting worm 14 is meshingly connected to the upper side of the second worm gear 13, and the right end of the adjusting worm 14 rotates and passes through the fixing plate 6, and the second worm gear 13 is driven to rotate by rotating the adjusting worm 14, and the second rotating shaft 12 is driven to rotate by the rotation of the second worm gear 13, and the support leg 7 is driven to rotate by the rotation of the second rotating shaft 12, and finally the adjustment of the support leg 7 on one side is realized. The above structure improves the flexibility of the device in actual use. When the device is used on an inclined road surface, the opening and closing angle of the support leg 7 on one side can be adjusted separately to ensure the level of the ranging device body 1, which is convenient for the staff to choose overall adjustment or separate adjustment according to the actual use environment, and the operation is simple.
[0029] Furthermore, a cavity is provided inside the supporting leg 7, and a second groove 15 extending from the two side surfaces is provided at the lower part of the supporting leg 7, and guide grooves 16 are provided on the inner walls of the second groove 15 on both sides, and a threaded rod 22 is rotatably connected inside the rear guide groove 16, and the rear guide groove 16 is communicated with the cavity inside the supporting leg 7, and the upper end of the threaded rod 22 extends into the interior of the supporting leg 7, and a first bevel gear 19 is sleeved on the outer surface of the upper end of the threaded rod 22, and a second bevel gear 20 is meshed and connected on the outer surface of the first bevel gear 19, and a driving rod 21 is sleeved inside the second bevel gear 20, and the right end of the driving rod 21 rotates and passes through the supporting leg 7, and a guide plate 17 is provided inside the second groove 15, and the two ends of the guide plate 17 are respectively slidably connected to the inside of the two guide grooves 16, and the rear end of the guide plate 17 is threadedly sleeved on the outer surface of the threaded rod 22, and the lower surface of the guide plate 17 is fixedly connected with a fixed cone 18, which is driven by the staff rotating the guide plate 17. The movable rod 21 drives the second bevel gear 20 to rotate, and the rotation of the second bevel gear 20 drives the rotation of the first bevel gear 19, and the rotation of the first bevel gear 19 drives the rotation of the threaded rod 22, and the rotation of the threaded rod 22 drives the guide plate 17 to slide inside the guide groove 16, and the movement of the guide plate 17 drives the movement of the fixed cone 18. The functionality of the device is improved by the above structure. When using the device on a cement road surface, the staff can increase the contact area between the device and the ground by making the two supporting legs 7 contact the ground, thereby improving the stability of the device when placed. When used on soft land, the staff can make the fixed cone 18 drop out of the second groove 15, so that the fixed cone 18 penetrates into the soil, thereby improving the placement stability of the device, further improving the practicality of the device, and facilitating the staff to flexibly adjust the placement method of the device according to the use environment.
[0030] Working principle:
[0031] When the highway engineering distance measuring device is in use, the staff rotates the active worm 9, and the rotation of the active worm 9 drives the rotation of the driven worm 10, and then drives the rotation of the two first worm wheels 8. Because the patterns on the surfaces of the active worm 9 and the driven worm 10 that mesh with the first worm wheels 8 are opposite, the rotation of the active worm 9 and the driven worm 10 causes the two first worm wheels 8 to rotate in the opposite direction, and the rotation of the two first worm wheels 8 drives the rotation of the first rotating shaft 5, and the rotation of the first rotating shaft 5 drives the connecting plate 4 to rotate inside the first groove 3, and the rotation of the connecting plate 4 drives the rotation of the fixed plate 6, and then drives the rotation of the supporting legs 7, and finally realizes the simultaneous opening and closing of the supporting legs 7 on both sides.
