Technical field
The utility model relates to colliery engineering technical field, is specially a kind of underground coal mine surrouding rock deformation and measures Sopwith staff.
Background technology
The tunnel roof-to-floor convergence roadway's sides amount of shifting near is comprised in deformation of the surrounding rock in tunnel amount, the anchor pole of the present scene a gang of supporting in common way Shi Jiang lane and the anchor pole of back supporting are measurement point, monitor the roadway's sides amount of shifting near and roof-to-floor convergence respectively, when measuring, a cord is helped out with money side amount point in tunnel fixing, and tension is in tunnel, and another helps point of fixity to fix, the measuring point of back in kind fixes cord, and suspension heavy weight is stretching by it, ride on the fixing rope in portion of side, then be that benchmark props up roof station by bottom Sopwith staff with Sopwith staff with suspension wire, measure the distance of side portion's static line to top measuring point, then Sopwith staff shortened and measure the distance of base plate to side portion's static line by propping up roadway floor bottom it, finally measure anchor pole top, portion of side and the distance vertically between suspension wire by propping up side portion's anchor pole bottom Sopwith staff along side portion's static line, then the distance of point of fixity is helped with tape measure or anchor pole top, portion of tape measure side and another, due to underground coal mine bad environments and bottom tunnel, side portion's point position and base plate situation are very easily subject to impact that is artificial and action of underground, due to the chronicity that limitation and the roadway deformation of existing Sopwith staff are measured, often there will be base plate fragmentation and can not find original measuring position, Sopwith staff can not along phenomenons such as rope measurement and reading error, and existing Sopwith staff exists the shortcomings such as process is loaded down with trivial details, precision is wayward when roadway deformation is measured in a word, for this reason, proposes a kind of underground coal mine surrouding rock deformation and measures Sopwith staff.
Utility model content
The purpose of this utility model is to provide a kind of underground coal mine surrouding rock deformation to measure Sopwith staff, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: Sopwith staff is measured in a kind of underground coal mine surrouding rock deformation, comprise top Sopwith staff and bottom Sopwith staff, described top Sopwith staff and bottom Sopwith staff are formed by least three joint Sopwith staff joint sockets, and the bottom of top Sopwith staff and bottom Sopwith staff is one-body molded, the junction of described top Sopwith staff and bottom Sopwith staff is rotatablely equipped with rotation Sopwith staff by coupling bar, described rotation Sopwith staff is rotated Sopwith staff joint by least three joints and is connected and composed by link slot, and the both sides rotating Sopwith staff joint are equipped with perforate.
Preferably, be provided with spacing block set inside the two ends of described coupling bar, the junction of described top Sopwith staff and bottom Sopwith staff is provided with the spacing cell body mated with the spacing block set inside the two ends of coupling bar.
Preferably, the spacing block set surface inside the two ends of described coupling bar is cambered surface, and the spacing cell body of described top Sopwith staff and Sopwith staff junction, bottom is deep-slotted chip breaker.
Preferably, be equipped with damping fin between described top Sopwith staff and every two rotation Sopwith staff joints of bottom Sopwith staff, and the ratio of damping equivalent of damping fin increases.
Preferably, be equipped with damping fin between every two rotation Sopwith staff joints of described rotation Sopwith staff, and the ratio of damping equivalent of damping fin increases.
Compared with prior art, the beneficial effects of the utility model are: this novel by set up bottom Sopwith staff and rotate Sopwith staff can realize only there is side portion's static line when, can realize thirdly by two fixing measuring points fixing, reduce artificial error, also realize disposable whole measurement of tunnel roof and floor and side portion's displacement, have that measuring accuracy is high, operation steps is few and the advantage such as structure is exquisite.
