Description

Technical Field

[0001] The utility model relates to the technical field of verticality measuring tools, in particular to a lamp pole verticality measuring tool. Background Art

[0002] The lamp pole of a street lamp is an important part of the street lamp. After installation, it is generally required to be perpendicular to the road surface. However, due to the long length of the lamp pole, after installation, even if there is a very small angle deviation between the part of the lamp pole close to the road surface and the vertical line perpendicular to the road surface drawn upward from the lower end of the lamp pole, the distance between the upper end of the lamp pole and the vertical line will be very large. Therefore, when installing the lamp pole, it is usually necessary to use a verticality measurement tool to detect whether the verticality between the lamp pole and the road surface meets the requirements before installation. Generally, the verticality of the street light pole is measured using the hanging ball method. On the one hand, this method is difficult to ensure the accuracy of the construction requirements. On the other hand, it requires construction workers to work at height, which poses a safety hazard. In addition, it is greatly affected by the weather and the construction period cannot be guaranteed.

[0003] The existing application number CN202321601557.1 is a street lamp pole verticality detection device, comprising a support assembly and a detection assembly for fitting with the lamp pole, the detection assembly comprising a chassis, a slider and a plurality of groups of springs, the chassis is fixed on the support assembly, the slider is arranged in the chassis and slides on the chassis, one end of the spring is fixed on the slider, the other end of the spring is fixedly connected to the side wall of the chassis, and the spring is evenly distributed on the side wall of the slider with the slider as the center; although the existing detection device can detect whether the lamp pole is tilted, it has a complex structure. When used, the support assembly must be buckled on the lamp pole first, and then the abutment rod must be adjusted to fix the fixing part, which is cumbersome to operate, and the outer wall of the lamp pole is relatively smooth, so the fixing effect of the fixing part cannot be guaranteed; at the same time, the spring in the detection assembly is prone to rust after long-term use, and when the elastic force of several springs is inconsistent, the tilt of the lamp pole cannot be accurately detected. At the same time, in windy weather, the wind will also put a certain pressure on the spring, and the accuracy of the measurement result cannot be guaranteed. Utility Model Content

[0023] like Figure 1 As shown, this embodiment provides a lamp pole verticality measuring tool, including a light strip 2 and a circular ruler 3; the light strip 2 is in a ring structure and is buckled on the lamp pole 1, and a plurality of laser lights are arranged on the light strip 2 at circumferential intervals, the laser lights are arranged at an angle and the laser light beams emitted by the laser lights are inclined to the side away from the lamp pole 1; the circular ruler 3 is placed on the ground and is concentrically arranged with the pre-installation point of the lamp pole 1, and a plurality of groups of marks are arranged on the circular ruler 3 at circumferential intervals, each group of marks includes a plurality of layers of marking lines 9, and the marking lines 9 on the same layer between the groups are arranged concentrically with the circular ruler 3. Among them, the inclination angle of the laser light is 20°-45°; the light strip 2 includes a left semicircular ring 201 and a right semicircular ring 202, and one end of the left semicircular ring 201 and the right semicircular ring 202 are hingedly connected by a hinge 67; the ring ruler 3 includes a left semicircular portion 301 and a right semicircular portion 302, and one end of the left semicircular portion 301 and the right semicircular portion 302 are hingedly connected by a hinge 67; in order to increase the friction between the lamp pole 1 and the light strip 2 and prevent the light strip 2 from slipping, an anti-slip pad is also provided on the inner side of the light strip 2.

[0024] When in use, before the lamp pole 1 is hoisted, the light strip 2 is first installed at the appropriate position of the lamp pole 1, and the plane where the light strip 2 is located is perpendicular to the lamp pole 1. Then, a ring ruler 3 is placed on the ground. Marks can be made on the ground outside the installation point of the lamp pole 1 in advance for placing the ring ruler 3 (for example: elastic ink line, reserved bolts, etc.), so that the placement position of the ring ruler 3 is concentric with the pre-installation point of the lamp pole 1; hoist the lamp pole 1 to the designated location, preliminarily connect the lamp pole 1 with the embedded bolts at the pre-installation point, and observe the position of the laser beam emitted by the light strip 2 on the ring ruler 3, that is, whether it is located on the same layer of markings 9 in each group of marks, to determine whether the lamp pole 1 is set vertically. If it is not vertical, make corresponding adjustments until the verticality of the lamp pole 1 meets the requirements, and then fix the lamp pole 1. After the lamp pole 1 is installed, the ring ruler 3 and the light strip 2 are opened and removed, and they can be used in rotation; wherein, the inner diameter of the light strip 2 is adapted to the lamp pole 1, and the light strip 2 can be glued to the outside of the lamp pole 1 by dispensing glue.

[0025] Furthermore, since the glue dispensing may have the problem of loose adhesion, in the present embodiment, the other end of the left semicircular ring 201 and the right semicircular ring 202 is provided with a locking mechanism for locking the lamp pole 1 and the light strip 2; the locking mechanism includes a locking bolt 8 and a locking nut, and one end of the left semicircular ring 201 and the right semicircular ring 202 connected by the locking mechanism is provided with a connecting ear, and a connecting hole is provided on the connecting ear, and the locking bolt 8 passes through the two connecting holes and is locked and fixed by the locking nut.

[0026] Furthermore, in order to ensure that the ring ruler 3 is in a horizontal state after being placed on the ground, a level bubble 4 is provided on the left semi-ring portion 301 and the right semi-ring portion 302, and leveling legs 5 are also provided on the lower sides of the left semi-ring portion 301 and the right semi-ring portion 302; the level bubble 4 can be used to determine whether the ring ruler 3 is in a horizontal state; when the road surface is uneven and there are potholes, the ring ruler 3 may tilt, and then the ring ruler 3 can be adjusted to a horizontal state by adjusting the leveling legs 5.

[0027] Furthermore, at least three leveling legs 5 are provided and are evenly arranged along the circumferential direction of the ring ruler 3 to ensure that the ring ruler 3 is placed stably.

[0028] Furthermore, the leveling leg 5 includes a base and an adjusting rod. The base is placed on the ground, the adjusting rod is vertically arranged and slidably inserted in the base, and an adjusting bolt is arranged on the base. The end of the adjusting bolt abuts against the outer wall of the adjusting rod to lock the adjusting rod. By loosening the adjusting bolt, the depth of the adjusting rod inserted into the base can be adjusted to adjust the total height of the leveling leg 5, and the adjusting bolt is tightened after the level bubble 4 is completely centered, that is, the ring ruler 3 is in a horizontal state.

[0029] When using this tool, by observing whether the position where the laser light hits the mark on the ring ruler 3 is located on the same layer of marking lines 9 of each group of marks, it is possible to quickly and accurately determine whether the verticality of the lamp pole 1 meets the standard; since this tool uses laser to determine the verticality, it will not be affected by strong winds.
