The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1, the present embodiment provides a measuring device for a structural surface of a core, which includes an angle digital display 1, a flat scale 2 and a groove scale 3. The angle digital display 1 is preferably a grid-type angle digital display (a display screen is arranged on the angle digital display 1), a columnar circular grid sensor is adopted (the columnar circular grid consists of a stator (circular sleeve) which is coaxially arranged, namely a main grid and a rotor (cylinder), namely an auxiliary grid, a series of teeth and grooves with equal width are engraved on the inner cylinder and the outer cylinder of the columnar circular grid, a variable capacitor is formed when the rotor rotates), a groove ruler 3 is connected with the main grid, and the auxiliary grid is fixedly connected with a flat ruler 2 (the specific connection mode can refer to the grid-type digital display angle meter).
The leveling rod 2 and the groove ruler 3 are made of stainless steel materials, are wear-resistant and folding-resistant, are not easy to bend, and are not easy to damage when not in use and are placed in the bearing box. The length of the flat rule 2 and the groove rule 3 is preferably 15cm (the width can be freely set), and the width of both is preferably 2.5cm. When the core is drilled by the dead-end rock and soil, a diamond drill bit with the diameter of 75mm and a double-layer core tube are generally adopted to drill and core in rock, the flat ruler 2 and the groove ruler 3 have certain thickness, and when the structural surface of the rock core is measured, the lateral surface of the rock core is placed on the groove ruler 3, and the two have more contact surfaces and can be placed more stably.
When measuring the core structural surface, the core structural surface is contacted with the flat ruler, the contact surface is relatively more, and when measuring, the core is placed relatively stably.
The handle 4 is fixedly arranged at the bottom of the slot ruler 3, so that the slot ruler 3 and the whole instrument can be conveniently taken and used.
When the structural surface of the rock core is measured, the groove ruler 3 is attached to the side surface of the rock core, and slightly rotates along the side surface of the rock core until the groove ruler and the side surface of the rock core are relatively fixed (the groove ruler can be clamped (clamping columns, namely, the groove ruler 3 and the flat ruler 2 clamp the rock core), and the rock core surface can be kept stationary by hand), so that the center line of the groove ruler is parallel to the center line of the rock core; in the state that the center line of the groove ruler is parallel to the central axis of the rock core, the hand-held handle slightly rotates along the side face of the rock core or slides along the central axis of the rock core, so that the plane of the flat ruler is overlapped with the structural face of the rock core; and reading the angle on the angle digital display to finish the measurement of the structural surface of the rock core. The angle can be directly read out, and the included angle between the structural surface of the rock core and the central axis angle of the rock core can be more easily found. In addition, the device is simple to operate, the basic action is simplified to lean-turn-slide, and the device is easy to learn and use.
