Description
Technical Field
The utility model belongs to lamp pole construction detection instrument specifically is a toper lamp pole installation straightness measuring tool that hangs down.
Background
Because the verticality effect of the installed lamp post cannot be tested after installation, whether the installation is qualified or not can be estimated only through visual inspection of an installer or a running rule, and the accuracy is not high. Because the lamp pole is irregular object (the object that has the slope on the surface), the guiding ruler can only be used for measuring horizontal and vertical object, and to having the object of slope, can't carry out accurate use. Workers can only rely on experience and selection of background references to verify verticality, large variables and low accuracy. The lamp pole can have the slope by itself because of the reason of production also is not the instrument of directly perceived measurement, therefore needs a reliable instruction instrument during toper lamp pole installation straightness construction that hangs down among the prior art urgently.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects in the prior art, the invention provides a tool for detecting the verticality of a lamp post, which is convenient for workers to adjust the verticality installation of the lamp post.
In order to achieve the purpose of the invention, the technical scheme provided by the invention is as follows:
a tool for measuring the mounting verticality of a conical lamp post comprises a long arm end, a short arm end and a dial, wherein the long arm end is connected with the short arm end through a pin shaft; the bottom of the long arm end is provided with a permanent magnet; a leveling bubble is arranged at the top of the short arm end; the top of the long arm end is also provided with a semi-circle dial, and the central point of the dial is the axial point of the pin shaft.
The pin shaft is provided with a locking fixing bolt.
The level bubble of short arm end is provided with two, is close the axle head one, is close the free end one.
A guide hole with the reserved width matched with the semicircular dial is arranged between the two level bubbles at the short arm end, and the dial can move in the reserved guide hole in a semicircular shaft mode.
This instrument provides the detection instrument for the straightness that hangs down of lamp pole installation, provides accurate, audio-visual construction reference instrument for the constructor. The lamp post can be subjected to multi-point correction, the error is extremely small, the accuracy is high, the installation accuracy of the lamp post can be effectively improved, and the construction quality is improved.
Drawings
FIG. 1: the whole structure of the measuring tool is a perspective view;
FIG. 2: the elevation structure of the measuring tool.
In the drawings, the main parts are illustrated by symbols:
1. a permanent magnet; 2. a long arm end; 3. a dial scale; 4. a level bubble; 5. a short arm end; 6. a pin shaft; 7. and reserving a guide hole.
Detailed Description
Because there is not the installation straightness detection instrument that hangs down to the toper lamp pole among the prior art, the workman can only rely on experience and the reference object of background to verify, and the variable is big, and the degree of accuracy is not high. The invention provides a measuring tool which can intuitively reflect the verticality of a tapered lamp pole with a slope on the surface and can be used for determining the verticality accurately.
Example 1:
as shown in figures 1 and 2, the tool for measuring the installation verticality of the conical lamp post comprises a long arm end 2 of 30 centimeters, a short arm end 5 of 10 centimeters and a 180-degree dial 3 with the radius of 10 centimeters.
The bottom of the long arm end 2 is provided with a permanent magnet 1. The permanent magnet 1 and the lamp tube are adsorbed, so that the long arm end can be integrally attached to the surface of the lamp pole. Specifically, the long arm end 2 can be made of solid wood with the length of 30 centimeters, the width of 3 centimeters and the thickness of 3 centimeters.
The short arm end 5 is made of a solid wood square with the length of 10 centimeters, the width of 3 centimeters and the thickness of 1.4 centimeters. The short arm end 5 is provided with a glass round bubble, namely a level bubble 4, and the short arm end 5 is connected with the long arm end 2 through a pin shaft 6, so that the short arm end 5 can rotate by taking the pin shaft 6 as a center. The connecting pin shaft 6 is also provided with a locking fixing bolt which can fix the relative clamping degree of the short arm end 5 and the long arm end 2. Specifically, the two level bubbles 4 at the short arm end 5 are arranged, one near the shaft end and one near the free end.
The dial 3 is a scale with the radius of 10 cm and the surface marked with angle scales of 0 to 180 degrees. The dial can also adopt a wood structure with the thickness set to be 1.4 centimeters.
The short arm end 5 is provided with a reserved guide hole 7 matched with the width of the dial scale, one end of the dial scale 3 is fixedly connected with the long arm end 2, the other end of the dial scale penetrates through the reserved guide hole 7, and the dial scale can move in a semicircular shaft mode in the reserved guide hole.
The use method of the measuring tool comprises the following steps: a. the long arm end is fixed on the surface of the conical lamp post through permanent magnet attraction; b. then adjusting the levelness of the short arm end, and referring to the leveling bubble to enable the short arm end to be in a horizontal state; c. locking the pin shaft through a fastening bolt, stabilizing an included angle between the short arm end and the long arm, and taking down a tool for fixing the included angle; d. whether the lamp post is a circular cone or a prismatic cone, three point positions are selected from other positions of the lamp post, the long arm end is attracted to the surface of the lamp post again, and whether the level bubble is kept at the central position or not is observed; e. if the level bubble is positioned in the middle at other positions, the conical lamp post is proved to be vertically installed when being installed, and the installation requirement is met; if the level bubble at any other position is not in the middle, the lamp post is proved to be unqualified to be readjusted and recalibrated until the lamp post is qualified.
And after the short arm end is adjusted to be horizontal, directly reading the scale value corresponding to the short arm end to obtain the inclination of the conical surface at the position. The lamp pole is convenient for the staff to master.
Compared with the prior art, the invention has the beneficial effects that: the perpendicularity detection tool for lamp pole installation provides an accurate measurement tool for constructors. This instrument can carry out the multiple spot school to right, the error is minimum, the rate of accuracy is high, can effectively improve the installation accuracy of lamp pole, improves construction quality and construction speed.
