Novel survey device for planning and design

Abstract

The invention discloses a novel survey device for planning and design. The novel survey device comprises a bottom plate, wherein a rotary disc is arranged at the top of the bottom plate; a thread rodis rotatably connected into the rotary disc; a sliding sleeve is arranged on the outer surface of the thread rod; the thread rod is in thread connection with the sliding sleeve; and a first bevel gearis fixedly connected with the top of the sliding sleeve. According to the novel survey device disclosed by the invention, in a survey operation process, a drill bit is clamped into a gap of a hard substance; when the drill bit stops rotating, an operator reversely rotates a rotary wheel in time to drive a second bevel gear to rotate; the second bevel gear is engaged with the first bevel gear to rotate; the first bevel gear drives the sliding sleeve to move upward along the thread rod, so that a bracket, a motor and the drill bit are driven to retreat in time; and a thread sleeve is rotated toadjust the distance between a first thread bracket and a second thread bracket, so that the bottom plate can be at a balanced state.

Description

technical field [0001] The invention relates to the technical field of surveying, in particular to a novel surveying device for planning and design. Background technique [0002] Geological planning, design and survey work is an important basic work for national economic construction and social development. The quality of its work is not only to ensure the statistics and analysis of national resources, but also related to the formulation of future relevant policies by the country. On-site survey and exploration are often used in geological planning. drill. [0003] Most of the existing geological exploration drills are large-scale survey equipment, and there are few small-scale survey equipment. Even if there are, they are all motor-controlled or fully manual. It is not easy to detect at any time, and it cannot be returned in time. It is very easy to damage the motor and drill bit, shortening the service life of the motor and drill bit. All manual surveys can only be perfor...

Problems solved by technology

[0003] Most of the existing geological exploration drills are large-scale survey equipment, and there are few small-scale survey equipment. Even if there are, they are all motor-controlled or fully manual. It is not easy to detect at any time, and it cannot be returned in time. It is very easy to damage the motor and drill bit, shortening the service life of the motor and drill bit. All manual surveys can only be performed on the surface, and it is difficult to survey deeper layers. Among the existing small survey equipment, there are many brackets. Few, even if there is a fixed bracket, it is not easy to maintain balance on uneven ground, which increases the risk of operation
