Problems solved by technology

[0002] With the development of science and technology and the progress of society, the country has been promoting the development of high technology. In the field of bridge construction, there has always been a relatively difficult technical problem, that is, how to control the position of the drill hole during bridge drilling construction, and how to accurately control the bridge drilling. The depth, size and angle of the drilled hole during construction, many existing equipment can only simply drill downwards, and cannot control the depth, size and angle of the drilled hole, so there is an urgent need for a device solve such problems

Abstract

The invention discloses a hole spacing measuring instrument. The instrument comprises a main body. A chassis extending downwards is fixedly arranged on the bottom end surface of the main body. A storage groove is formed in the left side end surface of the main body. A lifting sliding groove is formed in the top end surface of the main body. A bevel gear cavity is formed in the right side end wallof the storage groove. A first hydraulic cavity extending downwards is formed in the portion, located at the right side of the bevel gear cavity, of the main body. A hydraulic pipeline extending leftand right is fixedly arranged in the portion, located under the first hydraulic cavity, of the main body. The left side extending tail end of the hydraulic pipeline communicates with the bottom extending tail end of the first hydraulic cavity. A second hydraulic cavity extending downwards is formed in the bottom end wall of the lifting sliding groove. The bottom extending tail end of the second hydraulic cavity communicates with the right side extending tail end of the hydraulic pipeline.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a hole distance measuring instrument. Background technique [0002] With the development of science and technology and the progress of society, the country has been promoting the development of high technology. In the field of bridge construction, there has always been a relatively difficult technical problem, that is, how to control the position of the drill hole during bridge drilling construction, and how to accurately control the bridge drilling. The depth, size and angle of the drilled hole during construction, many existing equipment can only simply drill downwards, and cannot control the depth, size and angle of the drilled hole, so there is an urgent need for a device solve such problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hole distance measuring instrument, which can solve the above-mentione...
