Description

a supported level

technical field

The utility model relates to the field of engineering measurement, in particular to a leveling rod with supports.

Background technique

In engineering construction, engineers often need to carry out various engineering measurements on the terrain, and leveling is one of the important measurement items. However, the measurement must be carried out at the construction site. Due to the complex and diverse conditions on the site, and the fact that the surveyor needs to hold the leveling rod by hand, the leveling rod must not shake back and forth when measuring, so as to control the level bubble on the leveling rod to be in the center. However, in the measurement At the same time, the staff ran around various stations with a leveling rod, which was labor-intensive, the body trembled naturally, and the level bubble had to be controlled to center, which not only increased the difficulty of observation for the observers, prolonged the measurement time, but also caused inaccurate readings. When the ruler is rotated on the measuring point and reads again, the center point will deviate, causing the reading to be more inaccurate. Therefore, it is difficult to ensure the accuracy of the measurement.

The Chinese invention patent with the patent publication number CN102853818 discloses a "portable leveling rod support". The patent of the present invention relates to a portable bracket used in conjunction with a precision Invar barcode level gauge. All are provided with a fastening device, and the level gauge is arranged in the inner frame of the fixed frame through the fastening device.

The Chinese invention patent of patent publication number CN102661735 discloses a kind of " leveling ruler ruler pad ". The patent of the present invention relates to a leveling ruler pad for improving precision in surveying engineering. Its technical feature is that the leveling ruler pad is mainly composed of a cylindrical caliper groove, a vertical ruler pad base, a cuboid caliper groove, a circular level and It consists of three support legs with the same shape and size. The invention effectively reduces the measurement error caused by the shaking of the leveling rod held by the surveyor, and relieves the fatigue of the surveyor from stabilizing the leveling rod.

In the above-mentioned patents, after the level gauge is fixed by the portable level gauge bracket, the level gauge cannot be quickly rotated to observe the black and red surface readings; the invention of the level gauge ruler pad can reduce the error caused by the level gauge shaking, but the wind force is relatively large When using the gauge pad, the shaking of the level gauge cannot be controlled close to the pad, and the pad of the level gauge is close to the ground, which is inconvenient for the surveyor to level.

Contents of the invention

In order to overcome the deficiencies of the leveling ruler above, the utility model provides a leveling ruler with a support. The leveling ruler can not only reduce the workload of the surveyor while effectively controlling the shaking of the leveling ruler, but also can conveniently rotate the ruler body to observe Black, red surface readings, improve measurement accuracy.

The technical solution adopted by the utility model to solve its technical problems is as follows:

(1) A leveling rod with a support, which is composed of a leveling ruler plate, a circular level, a universal ball joint, a telescopic rod, a base, a spiral structure, and a handle, and is characterized in that: both sides of the leveling ruler plate face inward Hollow out 15mm~20mm, install the telescopic rod, install the circular level on the left side of the leveling plate, install the handles on the left and right sides of the leveling plate, and install the base at the bottom.

(2) The ground end of the telescopic rod is pointed and conical, and the other end is connected to the leveling rod through a universal round node. There is a helical structure in the middle of each telescopic rod. When the helical structure is rotated clockwise, the telescopic rod is extended and the spiral The structure rotates counterclockwise and the telescoping rod shortens.

(3) The base is composed of a bottom plate, connecting columns and connectors, with a total height of 80mm. In addition, the bottom plate is a triangular steel plate, and the connecting columns and the bottom plate are connected by universal ball joints, which can make the bottom plate stationary. The scale plate rotates in any direction.

(4) The scale on the level gauge plate starts from 80mm.

The beneficial effects of the utility model are as follows: (1) The length of the telescopic rod of the leveling rod with support can be adjusted to realize the balance of the leveling scale, and the stability of the leveling scale can be maintained under complex conditions, which reduces the workload of the surveyors and ensures The accuracy of the measurement. (2) The lower part of the supported leveling rod is equipped with a base, which is convenient for operation and saves time when the rotation of the black and red sides is required. (3) The leveling rod is simple in structure, low in cost, and easy to popularize and use.

detailed description

The technical scheme of the present invention will be further described below with specific examples:

(1) A leveling rod with a support, which is composed of a leveling rod plate 1, a circular level 2, a universal ball joint 3, a telescopic rod 4, a base 5, a spiral structure 6, and a handle 7, and is characterized in that: The two sides of the level gauge plate 1 are hollowed out 15 mm to 20 mm inwardly, and the telescopic rod 4 is installed. The circular level 2 is installed on the left side of the level gauge plate 1 .

(2) The landing end of the telescopic rod 4 is pointed and conical, and the other end is connected to the leveling plate 1 through the universal round node 3. There is a helical structure 6 in the middle of each telescopic rod 4, and the helical structure 6 is rotated clockwise. The telescopic rod 4 is elongated, the spiral structure 6 is rotated counterclockwise, and the telescopic rod 4 is shortened.
