The mining hole depth and slope angle measuring device has simple structure, light weight and exact position, can overcome the measuring errors caused by the unconsistency of the probe axle center and the hole axle center, thereby increasing measuring accuracy and work efficiency.
Description
Technical field
The present invention relates to measurement mechanism, specifically belong to the measurement mechanism of mining with blast hole depth and inclination angle.
Background technology
In the mining process of down-hole, rock drilling perforation operation is one important procedure, its quality quality is related to the mining quality and benefits, the mining technicians will design fanhole(s) according to the ore body situation before the rock drilling perforation operation, the mineral all with maximum possible collect, its parameter relates to the degree of depth and inclination angle, if the degree of depth inadequately then may have the useful ore body explosion of part and do not get off, not only cause the wasting of resources but also influence the mine benefit, if and the inclination angle does not reach requirement, the ore fragmentation that explosion is got off is too big, not only transportation difficulty and also may be also will be in the tunnel secondary blasting, this is a danger close.
The rock drilling perforating apparatus major part that use at present in mine, China down-hole is the homemade hydraulic jumbo that falls behind, what have only the use of small part mine is the imported hydraulic chassis, it is fixing to add that tunnel, working face, mine is difficult in perforation procedure, causes the location to slide and is offset, and big gun hole parameter is changed; Particularly mining geology situation in down-hole is very complicated, runs into zone of fracture through regular meeting, and highland nip, and crack and solution cavity often make the big gun hole of accomplishing fluently deform before blast charging, dislocation, even stop up.And the general gap that between perforation and explosion, has between 3-15 days, sometimes the time is longer, so before explosion, will carry out measurement and acceptance to the degree of depth and the inclination angle in the big gun hole accomplished fluently, find the timely perforations adding in big gun hole that distortion is serious on the one hand, to calculate explosive payload according to depth measurements on the other hand, reduce cost to save explosive.
At present, mining is with the measurement mechanism at blast hole depth and inclination angle, its structure is that the depth transducer in big gun hole is what separate with obliquity sensor, measuring a big gun hole will insert twice respectively and just can finish, cause operating rate not only lower, but also the axial line that can not guarantee to pop one's head in is consistent with axle center, big gun hole, causes measure error bigger, can not satisfy measurement requirement.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of convenient and simple for operation, probe axial line and axle center, big gun hole high conformity are measured mining accurate, simple in structure with blast hole depth and dip measuring device.
Realize the technical measures of above-mentioned purpose:
Mining is with blast hole depth and dip measuring device, it mainly reaches the pendulum that is connected with obliquity sensor by hole depth sensor, obliquity sensor and forms, it is: the hole depth sensor is connected in an end of hollow Mitsubishi's taper connecting rod, at the other end connection obliquity sensor of hollow Mitsubishi's taper connecting rod; Two groups of adjacent spring fixtures are housed on Mitsubishi's taper connecting rod; On the Mitsubishi's taper connecting rod behind the spring fixture, be provided with wire hole.
It is: every group of spring fixture is made up of three hat spring leafs; Every hat spring leaf is provided with regulating tank; Connect a hat spring leaf on the water chestnut conical surface of each Mitsubishi's taper connecting rod, and even layout.
It is: obliquity sensor is connected with Mitsubishi taper connecting rod by fixed cover; Obliquity sensor is connected with Mitsubishi taper connecting rod by fixed cover; Obliquity sensor can freely rotate around Mitsubishi's taper connecting rod.
It is: Mitsubishi's taper connecting rod is the expansion link of adjustable type.
The present invention is compared with prior art, and is simple in structure, in light weight, the advantage that the location is accurate, and it can overcome because of probe axle center and the inconsistent measure error that causes in axle center, big gun hole, has improved certainty of measurement, has improved operating efficiency.
