Technical Field

[0001] This utility model relates to the field of verticality detection, and in particular to a device for detecting verticality in road construction. Background Technology

[0002] In road construction, the installation of road signs is a crucial step. According to road sign construction specifications, the verticality of the road posts is a core requirement for quality control. Traditional methods for checking post verticality often use a spirit level equipped with a plumb line; however, this method has certain limitations in practical application.

[0003] Specifically, the contact position between the spirit level and the post significantly affects the accuracy of the test results. The most accurate results are obtained when the contact surface of the spirit level and the tilt direction of the post are on the same plane. However, in actual testing, it is difficult to quickly and accurately determine the precise tilt direction of the post with the naked eye, especially for road posts that are narrower at the top and wider at the bottom. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that it is difficult to quickly determine the tilt direction of road posts with the naked eye, and to propose a road construction verticality detection device.

[0030] 40. Handle. Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figure 1 - Figure 7 As shown, the present invention provides a road construction verticality detection device, comprising:

[0033] The card holder 10 has a handle 40 and is V-shaped. By holding the V-shaped card holder 10 with the handle 40, the column is inserted into the V-shaped groove of the card holder 10, so that the card holder 10 can adapt to the detection of columns with different outer diameters.

[0034] The verticality tester 20 includes a universal level 22 and a base 21 fixed on the mounting bracket 10. The angle of the base 21 is adjustable. When performing verticality testing on a column that is narrow at the top and wide at the bottom (hereinafter referred to as a conical column), since the taper of the conical column is known, the angle of the base 21 is adjusted to match the taper. Therefore, when performing verticality testing on the conical column, the universal level 22 is adjusted to a horizontal state by adjusting the angle of the base 21. Then, the base 21 is mounted on the conical column, and the direction of deflection of the central bubble of the universal level 22 can be observed to quickly determine whether the tilt of the conical column exceeds the standard range.

[0035] The auxiliary detector 30 includes a plumb bob 31 that moves freely on the mounting base 10. A laser pointer 34 is fixed on the plumb bob 31. The beam direction of the laser pointer 34 is collinear with the perpendicular line of the plumb bob 31. The laser pointer 34 is positioned above the universal level 22. At night, the laser beam of the laser pointer 34 is normally projected onto the center of the universal level 22. Under the action of the plumb bob 31, the beam of the laser pointer 34 is always in a vertical state. When the road post tilts, the projection point of the laser pointer 34 changes, so as to facilitate quick judgment during nighttime measurements.

[0036] like Figure 3 , Figure 4 , Figure 5 As shown, the card holder 10 includes a vertical rod 11 and two card plates 12. A slider 121 is fixed on one side of the card plate 12. A groove 111 adapted to the slider 121 is provided on the vertical rod 11. The bottom of the groove 111 is a closed structure so that the card plate 12 and the vertical rod 11 can be disassembled and assembled by the slider 121 and the groove 111. In this way, when not in use, the two card plates 12 can be removed and stacked to avoid bending or breaking when the two V-shaped card plates 12 are squeezed against each other.

[0037] Meanwhile, the threaded hole 112 of the upright 11 is internally threaded with a first bolt 13, and the head of the first bolt 13 covers the top of the slide groove 111. Thus, when the slider 121 is installed into the upright 11 through the top opening of the slide groove 111, it is threadedly connected to the threaded hole 112 by the first bolt 13, and the head covers the top, preventing the clamping plate 12 from slipping off the upright 11 during use.

[0038] like Figure 2 , Figure 6 As shown, a shaft 23 is fixedly installed on one side of the base 21, and a bearing 26 fixed on the upright 11 is rotatably connected to the shaft 23.

[0039] A protractor 27 is fixed to one side of the bearing seat 26. A limiting disk 25 with a pointer 251 is fixed to the end of the shaft 23 near the protractor 27. When the universal level 22 is in a horizontal state and perpendicular to the upright 11, the pointer 251 points to the "0" scale of the protractor 27. When the base 21 is flipped outward, the shaft 23 and the pointer 251 rotate accordingly. The pointer 251 and the protractor 27 work together to observe the tilt angle of the universal level 22, so as to adjust the tilt angle of the universal level 22 to be the same as the taper of the cone. When the two clamping plates 12 are clamped on the cone and the cone is in a vertical state, the center bubble of the universal level 22 is centered. After adjustment, a nut 24 is threaded to the end of the shaft 23 away from the pointer 251. Under the action of compression and / or friction, the adjusted base 21 is fixed on the bearing seat 26.

[0040] like Figure 3 , Figure 5 As shown, a bracket 35 with a circular hole 351 is fixed on the upright 11. A ball 36 is fixed on the top of the plumb bob 31. The outer diameter of the ball 36 is larger than the inner diameter of the circular hole 351. The surface of the ball 36 is coated with grease so that the bottom plumb bob 31 can move freely by rotating the ball 36 above the circular hole 351.

[0041] Preferably, the base 21 is magnetically fixed to the universal level 22. When the angle of the universal level 22 is adjusted, the position of its center point is offset from the projection point of the laser pointer 34. At this time, through the magnetic attraction between the universal level 22 and the base 21, after the angle of the base 21 is adjusted, the universal level 22 is moved so that the center point of the universal level 22 corresponds to the projection point when the verticality of the road cone is tested.

[0042] like Figure 7 As shown, the plumb bob 31 is fixed with a long threaded tube 32, which is threadedly connected to the ball 36 to facilitate the assembly and disassembly of the ball 36 and the plumb bob 31. At the same time, the switch button 341 of the laser pointer 34 is fixed to the side wall of the long threaded tube 32 to facilitate the switching on and off of the laser pointer 34.

[0043] like Figure 3 , Figure 7 As shown, a fixing block 33 is fixedly installed on the long threaded tube 32. When storing the device, the fixing block 33 is rotated to make the long threaded tube 32 spirally inserted into the sphere 36. When the fixing block 33 abuts against the lower surface of the round hole 351 of the bracket 35, the plumb bob 31 can be fixed on the bracket 35. By fixing the plumb bob 31, it is prevented from shaking and hitting the upright 11 during the carrying process.

[0044] Working principle: When the road post is cylindrical, the pointer 251 points to the zero mark of the protractor 27. Then, hold the handle 40 and place the card holder 10 against the cylinder, so that the inner wall of the card plate 12 is against the cylinder. At this time, the tilt of the cylinder can be determined by observing the offset of the center bubble of the universal level 22.

[0045] In addition, during use, it can also be rotated around the cylinder for detection, so as to perform multi-directional perpendicularity detection of the cylinder;

[0046] When the road post is a cone, the taper (i.e., slope) of the cone is known. For example, when the taper is 5 degrees, by rotating the base 21, the pointer 251 flips outward to point to the "5" mark on the protractor 27. When the holder 10 rests against the vertical cone, the central bubble of the universal level 22 is centered. When the cone tilts, the holder 12 rests against the cone, and the central bubble of the universal level 22 shifts. Thus, this device can quickly switch between cylindrical and cone types, and the operation is more convenient.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
