Abstract
The utility model discloses a coal mine ground stress horizontal orientation device convenient to push. The coal mine ground stress horizontal orientation device is composed of a pin hole, a locating rod, a sensor guide wire, a sensor storing box, a ground stress meter installation pin groove, a front end guide wire hole, a front end flange, a front end groove, a front end roller shaft, a front end roller, a rear end guide wire hole, a rear end flange, a rear end groove, a rear end roller shaft and a rear end roller. According to the coal mine ground stress horizontal orientation device, when a hollow package body is sent to a hole, the front end roller and the rear end roller integrally support the front end flange and the rear end flange so as to enable the front end flange and the rear end flange to be separated from the wall of the hole. When rubbles falling from the wall of the hole fall down on the front end flange and the rear end flange, due to the rolling action of the front end roller and the rear end roller, the probability that the front end flange and the rear end flange are clamped by the rubbles in the hole is greatly lowered, so that the hollow package body can be normally pushed and installed in the hole, and the requirement for normal operation of the ground stress testing is greatly met.
Description
Technical field
The utility model relates to a kind ofly can test geostatic stress the horizontal orientation instrument apparatus that the hollow inclusion is sent into instrument connection easily and fast.Be mainly used in geostress survey field, colliery.
Background technology
At present, stress relief by borehole overcoring technique is measured horizontal direction finder structure that geostatic stress uses and is laid case, the ground stress gauge wire guide, the ground stress gauge by pin-and-hole, flange, orientation lever, sensor conductor, sensor and several parts of cotter way are installed and form.Owing to using rig to tunnel or surrounding rock of chamber internal bore degree of depth General Requirements is greater than 4～5 times of tunnel diameter, boring is most after pore-forming can detritus inbreak phenomenon occur at superficial part, therefore at the usage level direction finder, the hollow inclusion can be hindered to flange when pushing in hole due to the detritus piece of collapse hole inbreak cause pushing not smooth, thereby affected the normal mounting of hollow inclusion, serious situation will cause the hollow inclusion to be stuck in broken hole, and then affect the programming of geostress survey.
Summary of the invention
Can not smoothly the hollow inclusion be pushed to the deficiency in hole in order to overcome existing geostatic stress horizontal direction finder, the utility model is reequiped on the basis of original geostatic stress horizontal direction finder, geostatic stress horizontal direction finder after repacking can overcome the obstruction of the detritus piece of slump in boring, easily and fast the hollow inclusion is sent in instrument connection.
The utility model relates to a kind of convenient colliery geostatic stress horizontal direction finder pushed, and it is laid case, the ground stress gauge by pin-and-hole, orientation lever, sensor conductor, sensor and cotter way, front end wire guide, front end flange, front end groove, front end roller shaft, front end roller, rear end wire guide, rear end flanges, rear end groove, rear end roller shaft, rear end roller are installed are formed.Described front end flange edge stays establishes the front end groove, and the rear end flange periphery stays establishes the rear end groove, and the front end roller is arranged in the front end groove by the front end roller shaft, and the rear end roller is arranged in the groove of rear end by the rear end roller shaft; Described front end flange is installed 4 front end rollers altogether, and rear end flanges is installed 4 rear end rollers altogether, and the front end roller has the evagination of part with respect to the front end flange edge, and the rear end roller has the evagination of part with respect to the rear end flange periphery.
Good effect of the present utility model: can overcome the impact of boring inbreak rubble, easily and fast the hollow inclusion is sent in instrument connection, greatly reduced the possibility that flange is stuck, the selection flexible design of roller is various, can suit measures to local conditions, improve the efficiency of geostatic stress test job.
