Problems solved by technology

[0003] The surveying and mapping of urban topographic maps mainly adopts flat-panel surveying and notation methods, and aerial photogrammetry can also be used. In the work of surveying and mapping urban three-dimensional topographic maps, it is necessary to carry out some underground surveying and mapping work. Or during the measurement method, it is usually necessary to lift the well cover first. The existing auxiliary devices generally use the continuous force acting on the well cover to lift the well cover. Because some well covers are soaked and rusted by rain for many years, this kind The continuous force acts on the manhole cover. Firstly, it will damage the auxiliary device and the manhole cover to a certain extent. Second, when the manhole cover is lifted, the manhole cover may fly up due to inertia, which is very dangerous. corresponding improvement

Abstract

The present invention belongs to the technical field of surveying and mapping, especially a three-dimensional terrain auxiliary surveying and mapping device for cities. Aiming at the problem that the existing devices are relatively dangerous, the following scheme is proposed, including a workbench, and two support rods are arranged symmetrically on both sides of the workbench , the bottom of the support rod is fixed with two inner rods, the bottom of the inner rod is covered with an outer tube, the top of the workbench is provided with a second chute, the second chute is slidably connected with a second slider, and the top of the second slider The mounting plate is welded, the mounting plate and the second slider are threaded through the same first screw, the bottom of the front end of the workbench is provided with a notch, two fourth sliders are symmetrically fixed on both sides of the notch, and two fourth A crowbar is arranged between the slide blocks. In the present invention, the crowbar is adjusted to a suitable position for exerting force, and the crowbar is moved up and down intermittently. Under the action of the first spring, the limiting mechanism generates vibration forces of different frequencies on the well cover, so that the vibration force and the well cover resonate. Thereby prying the manhole cover loose.

Description

Technical field [0001] The present invention relates to the field of mapping technology, in particular to an urban three-dimensional terrain auxiliary mapping device. Background [0002] The planning, design, construction and operation management of urban construction includes urban control surveying, urban topographic map mapping, compilation and drawing of various thematic maps, construction lofting during the construction of municipal projects, and deformation observation of important buildings. All kinds of civil buildings, industrial and municipal engineering construction in the city are guided by urban planning, and the preparation of urban planning requires topographic maps of various scales. With the development of urban construction, features and landforms are constantly changing. In order for the content of the topographic map to be consistent with the situation on the ground, it is necessary to revise the topographic map in a timely manner. [0003] Surveying and mapp...
