Problems solved by technology

We know that these measurements must be carried out outdoors. However, the outdoor environment is generally poor, especially in windy weather. In addition, the quality and external dimensions of the precision Invar barcode leveling rod itself are relatively large. It is difficult to straighten the leveling rod, which directly leads to large measurement errors
In addition, the entire measurement process relies on human hands to support the leveling rod, which is labor-intensive and causes natural trembling of the human body, which increases the difficulty of observation for the observer and prolongs the measurement time.
All in all, with this human-supported measurement method, the measurement accuracy and measurement speed cannot be guaranteed

Embodiment Construction

[0017] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the present invention relates to a portable leveling rod bracket. This embodiment takes the portable bracket used in conjunction with the precision Invar barcode leveling gauge as an example. It includes a fixed frame 1 with a frame structure and a The telescopic bracket 2, the rear end of the fixed frame 1 is provided with a V-shaped structure, and the telescopic bracket 2 and the V-shaped structure are fixedly connected by screws 9, thus forming an inverted V-shaped structure through two telescopic brackets 2 supporting structure. The size of the fixed frame 1 is made according to the actual size of the precision Invar barcode level gauge 3, and the inner wall circumferential direction is slightly larger than the precision Invar barcode level gauge 3 by 5mm, so that the precision Invar barcode level gauge 3 is conveniently loaded into the fixed frame 1 in the inner frame. The left and right sides of th...

Abstract

The invention discloses a support, and aims to provide a portable leveling rod support which is simple in structure and convenient to operate and improves the measurement accuracy and the measurement speed. The portable leveling rod support disclosed by the invention comprises a frame-structured fixed rack (1) and a telescopic support (2) fixedly connected with the fixed rack (1), wherein the left and right sides of the fixed rack (1) are respectively provided with a fastening device, and a leveling rod (3) is arranged in an inner frame of the fixed rack (1) through the fastening devices, so that the leveling rod (3) can be vertically erected and keeps stable, thereby reducing the working difficulty of the measurement personnel, avoiding measurement errors caused by wind effect or manual support, and improving the measurement accuracy and the measurement speed. The support disclosed by the invention is applied to the field of leveling rod supports.

Description

technical field [0001] The invention relates to a portable leveling rod bracket, in particular to a portable bracket used in conjunction with a precision Invar barcode leveling rod. Background technique [0002] In the construction of roads or railways, engineers often need to carry out various engineering measurements on the terrain where the roads or railways are located, and precision leveling is one of the important measurement items. We know that these measurements must be carried out outdoors. However, the outdoor environment is generally poor, especially in windy weather. In addition, the quality and external dimensions of the precision Invar barcode leveling rod itself are relatively large. It is difficult to straighten the leveling rod, which directly leads to a large measurement error. In addition, the entire measurement process relies on human hands to support the leveling rod, which is labor-intensive and causes natural trembling of the human body, which increas...
