Abstract
The utility model discloses a bituminous paving fatigue test device, including installing support, giant magnetostrictive stopper, drive hammer, laser displacement sensor, the installing support has four stabilizer blades, be provided with the bolt hole on the stabilizer blade, the giant magnetostrictive stopper is in through mounting screw the central upper portion of installing support, the giant magnetostrictive stopper has a power output shaft, the drive hammer with power output shaft threaded connection, laser displacement sensor puts to one side through the screw and installs on the installing support. The utility model discloses can carry in a flexible way, simple to operate, adapt to the fatigue test on on -the -spot road surface.
Description
Technical field
The utility model relates to the technical field, the particularly technical field of bituminous pavement fatigue test device that bituminous pavement detects.
Background technology
To have with it that driving is steady, comfortable, noise is low, maintenance is convenient in Modern Traffic medium pitch concrete road surface, be easy to the advantages such as reclaiming pitch and at home and abroad obtain in highway and urban road and apply more and more widely.Modern Traffic large discharge, heavy load, high speed are had higher requirement to bituminous pavement, bituminous pavement is shock-resistant, the ability of antifatigue has influence on road surface to a certain extent and collapses or the probability of happening of the bad phenomenon such as fracture, so be necessary regularly to carry out on-the-spot testing fatigue to bituminous pavement, need badly now a kind of can easy to carry, the bituminous pavement fatigue test device of being convenient to mounting arrangements.
Summary of the invention
The purpose of this utility model is exactly to design a kind of bituminous pavement fatigue test device, can to carry flexibly, easy for installation, to adapt to the testing fatigue on on-the-spot road surface.
For achieving the above object, the utility model proposes a kind of bituminous pavement fatigue test device, comprise mounting bracket, ultra-magnetic telescopic detent, hammer, laser displacement sensor; Described mounting bracket has four legs, described leg is provided with bolt hole, described ultra-magnetic telescopic detent is arranged on the central upper of described mounting bracket by screw, described ultra-magnetic telescopic detent has a power output shaft, and described hammer is threaded with described power output shaft; Described laser displacement sensor is arranged on described mounting bracket by screw is tilting.
As preferably, on the hammering road surface when initial focus of described laser displacement sensor is positioned at the work of described hammer.
The beneficial effects of the utility model: the utility model is by adopting ultra-magnetic telescopic detent as the PTO of bituminous pavement testing fatigue, significantly reduce the overall volume of equipment, and carry out Real-Time Monitoring by the laser displacement sensor road pavement situation of subsiding, improve detection efficiency, adopt bolt by leg fixed bottom boundary, convenient installation.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model bituminous pavement fatigue test device.
In figure: 1-mounting bracket, 2-ultra-magnetic telescopic detent, 3-laser displacement sensor, 4-hammer, 11-leg, 12-bolt hole, 21-power output shaft.
Embodiment
Consult Fig. 1, the utility model bituminous pavement fatigue test device, comprise mounting bracket 1, ultra-magnetic telescopic detent 2, hammer 4, laser displacement sensor 3; Described mounting bracket 1 has four legs 11, described leg 11 is provided with bolt hole 12, described ultra-magnetic telescopic detent 2 is arranged on the central upper of described mounting bracket 1 by screw, described ultra-magnetic telescopic detent 2 has a power output shaft 21, and described hammer 4 is threaded with described power output shaft 21; Described laser displacement sensor 3 is arranged on described mounting bracket 1 by screw is tilting.
The initial focus of described laser displacement sensor 3 is positioned on hammering road surface when described hammer 4 works.
Ultra-magnetic telescopic detent 2 is a kind of high frequency brake generator, the power that internal main is wanted produces under the field drives changed at high frequency by a giant magnetostrictive rod, is therefore provided with field coil in the periphery of giant magnetostrictive rod and is wound around the coil rack of field coil; Giant magnetostrictive rod is a kind of functional material, has magnetostrictive effect, and namely external magnetic field changes, and the length of rod can change.
Utility model works process:
The utility model bituminous pavement fatigue test device in the course of the work, mounting bracket 1 is bolted on bituminous pavement, what regulate the position of laser displacement sensor 3 to make initial focus aim at hammer hangs a little, when applying frequency conversion electric current to ultra-magnetic telescopic detent 2, ultra-magnetic telescopic detent 2 drives hammer 4 high frequency hammering bituminous pavement, now bituminous pavement generation slight depression, sinking degree can extract and identify and calculate from the collection displacement signal of laser displacement sensor 3.
The utility model, by adopting ultra-magnetic telescopic detent as the PTO of bituminous pavement testing fatigue, significantly reduce the overall volume of equipment, and carry out Real-Time Monitoring by the laser displacement sensor road pavement situation of subsiding, improve detection efficiency, adopt bolt by leg fixed bottom boundary, convenient installation.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
