Description
Technical field
The present invention relates to the special-purpose extension rod of a kind of 3 D laser scanning, belong to the spatial information field of measuring technique.
Background technology
The Goaf Area that mining mineral resource forms is the major hidden danger of Mine Safety in Production, and the people adopt the not clear goaf serious threat personnel in the pit of formation and the safety of equipment, the more seriously high speed blast that collapses suddenly of dead zone and shock wave causes casualties and damage of facilities, these all constitute a serious threat to Mine Safety in Production, and cause ecological deterioration, mineral resources to waste, therefore, obtaining goaf three-dimensional configuration and position administers significant for safety in production and dead zone.
Yet, at mine down-hole because down-hole high temperature, high humidity, high dirt, narrow space rugged surroundings, personnel can't enter or since security reason should not enter the goaf, traditional monitoring means can't be implemented to measure at all, at present, best means is to adopt mining three-dimensional laser scanner to be stretched into the goaf to carry out the mode of three-dimensional detection and obtain its accurate form.In most of the cases, be in connecting taxiway, by an extension rod is connected on the three-dimensional laser scanner, again instrument is stretched into the goaf.
By set up tripod scanning space status at the connecting taxiway edge, still owing to stretch into weak point, there is the blind area in the effect of traditional extension rod owing to block as shown in Figure 1, causes measuring the dead zone configuration.
Have in the prior art and a kind ofly need adopt the fixedly measuring method of extension rod of support bar when using in the down-hole, as shown in Figure 2, this extension rod is square structure, and is scalable in the use procedure, for the intensity that guarantees extension rod need increase volume, non-portable; And adopt two support bars to fix when using, and need two support bars are fixed on the connecting taxiway crag, it is large to implement difficulty, is difficult to wide popularization and application.
Summary of the invention
Installation difficulty, intensity difference, non-portable problem that the present invention exists for solving existing 3 D laser scanning extension rod, and then provide a kind of 3 D laser scanning special-purpose extension rod.For this reason, the invention provides following technical scheme:
The special-purpose extension rod of a kind of 3 D laser scanning, comprise adaptor (2), set bolt (3), upper connector (4), lower web member (5), the body of rod (6) and bracing frame (7), on upper connector (4) and lower web member (5), all have connecting hole, set bolt (3) is used for upper connector (4) is fixedly connected with lower web member (5), upper connector (4) is fixed on the body of rod (6) one ends, has portable bracing frame (7) on the body of rod (6).
The invention solves extension rod installation difficulty, intensity difference, non-portable problem under the mine down-hole mal-condition, provide a kind of 3 D laser scanning special-purpose extension rod, operation intensity in the time of can reducing the scanning of workman's underground goaf, thereby realize without Fast Installation, dismounting in the instrument situation, increase work efficiency.
