Portable bridge construction measurement device with roll-type electromagnetic fixed direction support seat

Abstract

The invention discloses a portable bridge construction measuring device provided with a coil type electromagnetic fixed trend bracket seat, which structurally comprises a peep tube, a movable rod, a device shell, a mounting seat and a movable adjusting device, wherein an inner rotating sleeve is in rolling fit with the movable rod at the inner side, so that three unconnected brackets are subjectedto directional adjustment and output to control the supporting angle of equipment; then an inner adjusting disk is used for limiting and fixing, so that an inner displacement bracket outputs downwards under the action of traction; a fixed rod and a spring belt are fixed, and the bending angle of the bracket of the inner displacement bracket is limited, so that the displacement bracket is fixedlyengaged into a rod for supporting and fixing, and can be bent into the inside of the device when it is not needed, so that the support of the device is stabilized, thereby making the measurement moreprecise.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a portable bridge construction measurement device provided with roll-type electromagnetic fixed direction support seats. Background technique [0002] Bridge measurement usually uses a telescopic tripod as a fixed fulcrum, and then adjusts the position of the measuring device installed on the tripod by lifting and lowering according to the terrain, so as to perform numerical measurement of bridge construction, but in this way: [0003] During the measurement work, the telescopic tripod is used for movable support, but the telescopic bracket has a certain shrinkage limit. After fully shrinking, there will still be a section of the packaged outer frame exposed, thereby increasing the placed space. area, and with the telescopic rod body, the exposed shell is not protected by storage in a long-term working environment, and it is easy to make the internal displacement and take-up po...

Problems solved by technology

[0003] During the measurement work, the movable support is carried out by the telescopic tripod, but the telescopic bracket has a certain contraction limit. After the complete contraction, there will still be a section of the packaged outer frame exposed, thereby increasing the placed space. area, and with the telescopic rod body, the exposed shell is not protected by storage in a long-term working environment, which is easy to make the internal displacement and take-up position, which affects the measurement accuracy of the equipment
