Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a portable construction site distance measuring device for bridge engineering design. Background Art

[0002] During the construction of roads and bridges, it is necessary to measure the length and width to facilitate error-free construction and not affect the quality of roads and bridges. A distance meter will be used during measurement, eliminating the need for manual measurement by technicians and improving the accuracy of distance measurement.

[0003] The existing level is fixed at one point and can only rotate but cannot move. If it is to be moved, it is necessary to move the level to a fixed point and then slowly adjust it. It is okay if the movement is a long distance, but if the movement is a small displacement, it is very inconvenient to move it back and forth like this, and it also requires slow adjustment. Moving it back and forth also reduces the service life of the level.

A pull rod is slidably connected to the side of the main body away from the gear, and the pull rod passes through the main body and is fixedly connected to a gear block. In this measuring device for road and bridge construction, rotating the rotating rod drives the telescope to move left and right, and rotating the threaded rod can drive the telescope to move forward and backward.

[0005] Although the above patent can move the position of the measuring device, when the user uses the device at different measurement locations, the height of the measuring device cannot be adjusted, which makes the device have certain limitations when used, increases the difficulty of the surveyor's work, and is inconvenient for users to use. Therefore, it is necessary to invent a portable construction site distance measuring device for bridge engineering design to solve the above problems. Summary of the Invention
