Auxiliary orienting device for civil blasting operation field

Abstract

The invention discloses an auxiliary orienting device for civil blasting operation site, which comprises a box body. A partition plate is arranged inside the box body. The partition plate divides the box body into a first cavity and a second cavity. A total station body is provided in the cavity, and a placement groove matched with the total station body is provided on the partition plate, and a support plate is provided on the side of the total station body close to the partition plate, and the support plate is far away from One side of the total station body is hinged with three sets of support legs, and the ends of the three sets of support legs away from the support plate are all provided with an adjustment device, the adjustment device includes a limit plate, a connecting collar, an adjustable rod, a plug-in plate, Limiting slots and top plate. The invention is simple in structure and novel in design. The total station body and supporting device are put into the box, which is convenient for the user to carry and transfer. At the same time, one person can complete the adjustment of the total station. level to ensure the accuracy of the test results.

Description

technical field [0001] The invention relates to the field of orientation devices, in particular to an auxiliary orientation device for civil blasting operations. Background technique [0002] In recent years, with the country's emphasis on environmental resource protection and the promotion and use of new building materials, kilns that used clay as raw material to fire red bricks have been closed one after another. After the kiln was closed, the kiln body and the chimney had to be demolished for reclamation. Due to the tall chimney, the method of directional blasting was basically adopted for dismantling the chimney. When blasting tall cylindrical buildings such as chimneys and water towers, the surrounding environment of some buildings is very complicated, and the range of collapsible directions is limited, sometimes only 20 to 30 degrees. G point) accurately locate the operation target point (H point) on the chimney. However, in actual operation, it is very difficult to ...

AI Technical Summary

Problems solved by technology

However, in actual operation, it is very difficult to accurately find the required operating target point on the chimney wall.

[0003] Using the total station to determine the blasting point can ensure the accuracy of the detection, but it requires the cooperation of multiple people to complete the support and adjustment of the total station. Since the ground of the measurement site may not be flat enough, the total station cannot guarantee its levelness during installation. , will affect the detection results, measure the wrong blasting point, and affect the use. For this reason, we have designed an auxiliary orientation device for civilian blasting operations to solve the above problems
