Description

Leveling device that can be operated by one person

technical field

The utility model belongs to the field of geodetic and engineering surveying, in particular to a single-operated leveling measuring device which is suitable for engineering construction in a small area, saves manpower and improves work efficiency.

Background technique

A traditional level measuring device is composed of a level and two leveling rods. When measuring, first place the two leveling rods on the ground at points A and B respectively, then set the level at the middle position of the two points A and B, and use the horizontal line of sight of the leveling instrument to read the two levels respectively The elevation value of the ruler, the difference between the measured elevation values is the level difference between the two points A and B on the ground. The traditional leveling device requires at least 3 people to work (one person operates the level, and two people place the leveling rod). The Chinese patent with the patent application number 201220611636.6 discloses a "composite level combined with a ruler and meter for dual observation" (hereinafter referred to as a composite level). Its structure is to have a cylindrical ruler and a level. A leveling staff parallel to the axis of the cylindrical scale body and an observation unit that can slide up and down are fixed on the same cylindrical surface. The collimating axis of the measuring device is perpendicular to the axis of the cylindrical ruler. This patent places the level on the leveling staff for the first time, realizing the integration of the leveling unit and the leveling staff. When measuring, two composite levels are required to be paired and used, and the principle of dual observation is adopted. The above patent application requires at least 2 people to work (2 people) Simultaneous operation of 2 compound levels respectively).

The Chinese patent No. 201220373858.9 discloses a "clip-type measuring tripod", which mainly changes the base of the traditional tripod from a flat plate to a ring, and at least three The horizontal top wire provides a special measuring tripod for the measuring ruler for the first time. In order not to block the measuring scale, the Chinese utility model patent No. 201310022381.9 discloses a "clip-type measuring tripod". The base is changed into an open ring shape, and two horizontal top wires are arranged on the base The front end of the horizontal top wire is provided with a fixed connection device, or three horizontal top wires are arranged on the base, and the front end of the central horizontal top wire has a fixed connection device; the axes of the adjacent horizontal top wires are perpendicular to each other. During measurement, the leveling rod can be fixed by the measuring tripod, so as to avoid the problem of the surveyor holding the leveling rod, but it also requires at least two people to operate separately.

The above-mentioned leveling device or composite level is very suitable for long-distance wire leveling, but when the leveling is carried out in a small area of engineering construction (such as foundation leveling, square construction, etc.), it will cause a waste of personnel.

Detailed ways

Example 1:

As shown in Figure 1: a prismatic leveling rod 1 with scale divisions on the surface is provided, the prismatic leveling rod 1 is fixedly connected with the tripod 2, a circular level 3 is installed on the prismatic leveling rod 1, and the tripod 2 It consists of a ring-shaped frame head 21 (a clip-on measuring tripod in the prior art) and three first legs 22; a rectangular leveling rod 4 with a scale on the surface is provided, and the rectangular leveling rod 4 and the orthogonal two The tripod 5 is fixedly connected, and the rectangular leveling rod 4 is equipped with an L-shaped level 6, a height measuring device 7 and an observation hand book 8, and the height measuring device 7 and the observation hand book 8 realize signal connection through a wired or wireless communication device; The orthogonal tripod 5 consists of an open ring-shaped head 51 (a clamp-type measuring tripod in the prior art), two second legs 52 arranged orthogonally and a pedal mounted on the second legs 52 Rod 53 constitutes.

Use process: the prismatic leveling rod 1 is placed on a fixed benchmarking point through the tripod 2, and the bubble of the observation level 3 is centered so that the prismatic leveling rod 1 is in a vertical state. Then the rectangular leveling rod 4 is placed on the surrounding ground points to be measured and facing the prismatic leveling rod 1, the second leg 52 of the orthogonal tripod 5 is opened, and the pedal rod 53 is stepped on with one's feet, through the observation level 6 The air bubbles make the rectangular leveling rod 4 in a vertical state, and then use the height measuring device 7 and the observation hand book 8 to measure the line-of-sight height of the prismatic leveling rod 1, and calculate the height difference between the ground point to be measured and the fixed leveling point.
