Detailed Description

The present invention will be further described with reference to the following embodiments. Wherein the showings are for the purpose of illustration only and are shown by way of illustration only and not in actual form, and are not to be construed as limiting the present patent; for a better understanding of the embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.

Example one

As shown in fig. 1-2 and 4, the portable detachable face layer thickness detection tool provided by the embodiment includes a hollow drill bit 1, an adjustable support 2, a leveling bubble 3, a leveling instrument 4, a threaded electric shaft 5, a motor 6, an electric hand drill 7, a detachable lithium battery 8, a start button 9, a handle 10, a scale 11, and a drilling support 12. The front end of the body of the electric hand drill 7 is provided with a drilling support 12, the hollow drill bit 1 penetrates through the drilling support 12 and then is connected to the electric hand drill 7, the end, away from the electric hand drill 7, of the drilling support 12 is provided with at least three adjustable foot supports 2, in the embodiment, the four adjustable foot supports 2 are arranged, and the four adjustable foot supports can be rotated to realize the level of the drilling support; the drilling support 12 is also provided with four levels 4 with built-in level air bubbles 3, and the number of the corresponding levels is one-to-one corresponding to that of the adjustable foot supports 2. The adjustable foot support 2 adopts screws or pins. And be equipped with motor 6 on electric hand drill 7, can dismantle lithium cell 8, start button 9 and handle 10, the output shaft of motor 6 is established to the threaded electric axle 5 of being connected with hollow drill bit 1, also can conveniently dismantle when guaranteeing to drill and get the core, motor 6 through start button 9 with can dismantle 8 electric connection of lithium cell. The body of the electric hand drill 7 and the hollow drill bit 1 are transparent or semitransparent, and the hollow drill bit 1 is provided with scales 11. Adopt above-mentioned scheme, this portable detachable pitch surface course thickness detects instrument, it gets core convenient and fast, and the drill bit is convenient to be dismantled and is changed, and through combining together with electric hand drill for the drill bit is not big, destroys on original road surface for a short time, and whole volume is also less, light in weight, portable and operation. The drilling operation of the inspection tool can also be stabilized by the drill hole supporter. Still adopt detachable lithium cell, convenient real-time change operation, the drilling hole is less to the road surface loss and can on-the-spot real-time detection surface course thickness simultaneously to the high-efficient quick quality of detecting pitch highway.

When in use, the adjustable foot supports 2 on the drilling support 12 are rotated at a sampling site to enable the leveling bubble 3 in the leveling instrument 4 to be positioned at the central position, so that the whole drilling support 12 is kept relatively horizontal, and the relative verticality of drilling operation is ensured. And then starting a starting button 9 of the electric hand drill 7, carrying out drilling coring operation through the hollow drill bit 1 in the central vacancy of the drilling support 12, and lifting the operation stability by holding the handle 10. Get the core operation in-process, the electric hand drill body and the hollow drill bit of accessible transparent form look over in real time and bore and get the process, are convenient for see clearly the structural style of the pitch core appearance surface course of getting and different surface courses juncture to scale through on the hollow drill bit reads pitch surface course thickness, makes it detect the surface course thickness under the condition of not taking out the core appearance.

A weighted filler is provided within the borehole support 12 in this embodiment. The stability of the detection tool is further improved by increasing the weight of the drill hole support.

Example two

Referring again to FIG. 3, the tool further comprises a core sample receiving cylinder 13 for receiving a sample from the hollow drill bit 1 and having a scale value. Like this, after accomplishing the drilling sample, can pour the core appearance among the hollow drill bit into in the core appearance receiving cylinder, the reading of the pitch surface course thickness of getting is bored to the scale value on the rethread core appearance receiving cylinder, and after waiting to read and accomplish, can directly fall back the core appearance sampling point, when guaranteeing pitch surface course thickness detection like this, realize the minimum loss to road surface wholeness.

Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all of them should be covered by the scope of the claims of the present invention.
