Problems solved by technology
There are many disadvantages in this detection method: manual lifting of the antenna is particularly laborious and prone to fatigue; the relative height of the vault or the waist of the arch and the road surface in the tunnel changes at any time. The antenna cannot be closely attached to the lining, which affects the quality of the collected images; the technical requirements for the loader driver are high; the return measurement rate is high, and the work efficiency is low, which sometimes seriously affects the normal construction progress of the tunnel

The invention discloses a geological radar antenna plunger type hydraulic bracket for tunnel lining detection. The geological radar antenna plunger type hydraulic bracket comprises a bracket bottom plate, and an engine, a hydraulic pump, a load-sensitive valve, an oil tank, a plunger type hydraulic cylinder block, a lifting frame and an antenna tray which are arranged on the bracket bottom plate, wherein an output shaft of the engine is connected with a driving shaft of the hydraulic pump; the oil inlet of the hydraulic pump is communicated with the oil outlet of the oil tank; the oil outlet of the hydraulic pump is communicated with a control port of the load-sensitive valve; another control port of the load-sensitive valve is communicated with the oil inlet of the plunger type hydraulic cylinder block; the oil outlet of the load-sensitive valve is communicated with the oil inlet of the oil tank; a plunger of the plunger type hydraulic cylinder block passes through a cylinder cover of the plunger type hydraulic cylinder block, and is connected with the lower end of the lifting frame; the upper part of the lifting frame is connected with the antenna tray. By adopting the geological radar antenna plunger type hydraulic bracket, a geological radar antenna can be supported.
Description
technical field [0001] The invention belongs to the technical field of tunnel lining detection equipment, and relates to a geological radar antenna plunger type hydraulic bracket for tunnel lining detection. Background technique [0002] Our country pays more and more attention to the development planning and construction of highways. The road network in various places is becoming more and more dense, and the proportion of road tunnels in road construction is increasing. During the construction of highway tunnels, quality inspection departments, third-party inspection units or construction units often inspect the thickness and quality of their linings. At this time, the non-destructive testing method of ground radar is commonly used. [0003] Ground radar detection equipment is mainly composed of radar antenna, cable, and host. The cable is used to connect the antenna and the host, and the length of the cable is generally long enough. At present, the on-site inspection sti...
