Description
Technical field
The utility model belongs to road surface sampler field, is a kind of detection of damage caused by water on asphalt pavement with taking specifically
Sampling device.
Background technology
So-called water destruct is road surface is produced the phenomenon of early damage after precipitation penetrates road surface structare layer, and it is current pitch
The maximum a kind of disease of most common and destructive power in the early disease of concrete road surface.The main damage form of water destruct has:Net
Split, pit-hole, purt slurry, rut groove etc..The generation of water destruct controls not tight, pitch often caused by mixture ratio of asphalt concrete in construction
Caused by bituminous paving voidage caused by compound mix is uneven, rolling effect is bad etc. is excessive；For the pitch of laying
Road surface carries out detection and is necessary；But current chisel bit, road surface core sample easily comes off operation inconvenience during coring.
Utility model content
The utility model purpose be intended to provide it is a kind of it is simple and reasonable, prevent road surface core sample from coming off, convenient use
Damage caused by water on asphalt pavement detection sampler.
To realize above-mentioned technical purpose, the technical solution adopted in the utility model is as follows：
A kind of damage caused by water on asphalt pavement detection sampler, including pedestal, the pedestal are provided with gag lever post, the limit
Position bar is vertically arranged and lower end is fixedly connected with pedestal, is cased with installing support plate on the gag lever post, the installation support plate left end can
That slides is placed on gag lever post, is also inserted with screw rod at the installation support plate center and is connected by screw thread with screw rod, the screw rod
Lower end is embedded in pedestal upper surface, is fixedly installed motor on the left of the installation support plate lower surface, the motor is vertical
Being set in mounting base, drill bit is connected with the driving motor output shaft, the drill bit is the circular cylindrical cavity of lower ending opening,
The drill bit openend is provided with some first grooves, and brill tooth is equipped with some first grooves, and the brill tooth upper end passes through
Rotating shaft is connected with the first recess sidewall, and the brill outside side in tooth upper end is provided with projection, and the brill tooth lower end is outside arc,
Outer tube is also cased with outside the drill bit.
Using the utility model of above-mentioned technical proposal, drill bit is driven by motor, can by rotate screw rod make its
Slided on gag lever post, reached the purpose for the road pavement drilling that drill bit rises or falls；Outer tube is cased with outside drill bit, when drill bit to
During upper motion, outer tube moves downward with wall friction in the hole bored on road surface, due to boring the outside side in tooth upper end provided with convex
Rise, outer tube lower end will promote projection, then because boring what tooth was connected by rotating shaft with the first recess sidewall, boring tooth lower end will
Inwardly collapse, the road surface core sample clamping that drill bit is included, prevent it from coming off, convenient use.
Further limit, if the overcoat pipe outer wall is provided with arterial highway annular ridge.
Overcoat pipe outer wall and the friction of hole inwall are improved, ensures that outer sleeve moves down when drill bit moves up.
Further limit, the pedestal is provided with the second groove with screw rod junction, and the screw rod lower end is embedded in the second groove
It is interior.
It is spacing to screw rod lower end, prevent screw rod bias effect from using.
Further limit, bearing is embedded between the screw rod lower end and the second groove.
The friction between screw rod and groove is reduced, makes rotation screw rod more laborsaving, screw rod upper end can also set rotating disk, side
Convenient to operate.
Further limit, pedestal corner lower end is equipped with pulley.
Facilitate drilling-machine shifter.
The utility model is compared with prior art, simple and reasonable, prevent road surface core sample from coming off, convenient use.
