Abstract

The utility model discloses a level device for rapid equidistant measurement, which comprises a level body, wherein a bottom plate is fixedly arranged on the top surface of the level body through four suckers, a base is arranged at the center of the bottom plate, a ball head connecting rod assembly is arranged at the center of the base, a laser pen box is horizontally arranged at the top end of the ball head connecting rod assembly, and a laser pen is arranged in the laser pen box. When the reading of the rear ruler is finished, the light emitting point of the laser pen is aligned to the ground point of the rear ruler, when the level is turned to the direction of the front ruler, the light emitting point of the laser pen is simultaneously turned to the direction of the front ruler, and the irradiation position of the ground point is the vertical ruler position of the front ruler, so that the labor can be saved, and the working efficiency can be greatly improved.

Description

Level gauge device for rapid equidistant measurement

Technical Field

The utility model relates to the technical field of engineering measurement. A found chi position of ruler before the short-term test for when leveling to satisfy the standard requirement of ruler equidistance around among the leveling, can make on-the-spot leveling convenient, swift. In particular to a level device for rapid equidistant measurement.

Background

Leveling is an essential important work in engineering surveying and mapping, leveling needs to be carried out in various fields such as line measurement, tunnel measurement and pipeline measurement to obtain the elevation in an engineering project area, and commonly used measuring instrument equipment is a level gauge and a leveling rod. According to the requirements of engineering measurement specifications, when leveling is carried out, the distances between the leveling instrument and the front ruler and the distances between the leveling instrument and the rear ruler are equal, so that the i-angle error of the instrument and the influence of atmospheric refraction are counteracted, and the measurement precision is achieved. The conventional method for determining the equal distance generally comprises the steps of measuring the number of steps of a person on the rear ruler to a level, determining the position of the front ruler according to the same number of steps, and due to the influence of various factors such as the walking direction and the like, the requirement of the equal distance between the front ruler and the rear ruler is difficult to achieve at one time, the requirement of the equal distance can be met after multiple adjustments are often needed, and the field work efficiency is low. The other method is to pull a ruler, measure the distance from the rear ruler to the level by using the rope ruler, and determine the position of the front ruler according to the distance from the rear ruler. By adopting the rope ruler measuring method, the staff for erecting the ruler is often not smoothly matched with the staff for the rope ruler, the working efficiency is low, meanwhile, a special person is required to be equipped for rope ruler measurement, and 2 additional measuring staff are required to be added for one leveling group.

Disclosure of Invention

In order to improve the field working efficiency and reduce field operation personnel, the utility model provides the level device for rapid equidistant measurement, which can rapidly determine the vertical ruler positions of the front ruler and the rear ruler, improve the working efficiency and save manpower.

The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a surveyor's level device for quick equidistance is measured, includes the surveyor's level body, is setting up a bottom plate through four sucking discs are fixed on surveyor's level body top surface, and bottom plate center department is setting up the base, and base center department is setting up bulb link assembly, and bulb link assembly's top level is setting up the laser pen box, is equipped with the laser pen in the laser pen box.

After the reading of the rear ruler is finished, the laser pen light-emitting spot is aligned to the rear ruler ground point, when the level is turned to the front ruler direction, the laser pen light-emitting spot is turned to the front ruler direction at the same time, and the irradiation position of the ground point is the front ruler vertical position. The utility model has the beneficial effects that: 1. one level team can save 2 people on the pull rope ruler. 2. The positions of the front and rear vertical rulers can be quickly determined, and the field work efficiency is improved.

Detailed Description

The utility model provides a surveyor's level device for quick equidistance is measured, as shown in figure 1, including surveyor's level body 1, is setting up a bottom plate 3 through four sucking discs 2 are fixed on 1 top surface of surveyor's level body, and 3 center departments of bottom plate are setting up base 5, and 5 center departments of base are setting up bulb link assembly 8, and the top level of bulb link assembly 8 is setting up laser pen box 7, is equipped with laser pen 6 in the laser pen box 7. The structure of the ball-head connecting rod assembly 8 is the same as that of a ball-head connecting piece on the vehicle-mounted mobile phone frame, 360-degree rotation can be achieved, the vertical or inclined state can be kept, and operation is convenient.

After the reading of the rear ruler is finished, the emitting point of the laser pen 6 is aligned to the ground point of the rear ruler, when the level is turned to the direction of the front ruler, the laser head is turned to the direction of the front ruler, and the laser point position on the ground in the direction of the front ruler is the vertical ruler position of the front ruler.

Claims

1. The utility model provides a surveyor's level device for quick equidistance is measured, includes the surveyor's level body, characterized by: a bottom plate is fixedly arranged on the top surface of the level body through four suckers, a base is arranged at the center of the bottom plate, a ball head connecting rod assembly is arranged at the center of the base, a laser pen box is horizontally arranged at the top end of the ball head connecting rod assembly, and a laser pen is arranged in the laser pen box.
