Description
Technical field:
The utility model relates to highway pavement quality examination experimental technique, be particularly related to the automatic compaction test apparatus of a kind of dual-use formula Marshall, be used for the shaping preparation of highway pavement standard or large-scale cylinder test specimen sample, carry out the test of asphalt physico-mechanical properties for testing laboratory.
Background technology:
Development and national economy depends on flourishing traffic, and various haulage vehicles are day and night seething on the highway, certainly will require highway to possess superior pavement quality, and highway pavement mainly adopts compounds such as pitch, rubble, breeze to form through pressing in fact to lay at present.The important evidence that the paving engineering quality is managed is the test figure of test agent, and the automatic compaction test apparatus of Marshall is the indispensable instrument for preparing sample by national regulation.Similar substantially on the automatic compaction test apparatus structure of the Marshall that appears on the market now, generally all partly instruct kinematic train to finish the positive activity that hits of sample by control, and be that a machine can only hit real a kind of sample slug, as: the standard sample post of the pitch of Φ 101.6mm * 63.5mm and small particle diameter macadam-aggregate mix.In recent years, relevant department's research is both at home and abroad thought, highway pavement damages in addition, and a reason is the quality that deep layer road surface (the downward 5-10 centimetre in the face of land) quality directly has influence on road surface, top layer (downward about 5 centimeters of the face of land), thereby think to its mechanical property of the also essential preparation sample testing of deep layer road surfacing, pitch that this sample national regulation is referred to as large-scale sample Φ 152.4mm * 95.3mm and big particle diameter macadam-aggregate mix), and the compaction test apparatus for preparing this specification sample needs another kind to be referred to as large-scale compaction test apparatus.So, prepare sample at the construction field (site) and must prepare enough two automatic compaction test apparatuses of cover Marshall, otherwise can not meet the demands.
Summary of the invention:
The utility model is at the problems referred to above, provide a kind of device dual-use formula Marshall automatic compaction test apparatus, its by same control partly by gearshift control two cover transmissions, hit real system and finish standard sample, the preparation work of large-scale sample, also the hammer lifting mechanism and the hammering damping that hit real system are innovated simultaneously, purpose is that under the prerequisite that satisfies the specimen preparation requirement more it simplifies the structure of the automatic compaction test apparatus of Marshall.
Technical solution of the present utility model: compared with prior art, the utility model has comprised a switch board and a mainframe equally, comprise kinematic train that two covers put side by side in the mainframe that is it that they are different, hit real system, and be provided with arrangement of clutch at the driving wheel place of kinematic train, can make separately independently kinematic train, hit real system and hit real preparation various sample respectively, control shows part commutation circuit connected mode and obtains corresponding data.Described arrangement of clutch is made up of two parallel with the driving wheel of two cover kinematic trains respectively gear shift sprocket wheel, change gears and the handle that is connected with this wheel shaft.Its course of work is a turning handle, the driving wheel engage a gear of change gear and one of them legacy system, then this side kinematic train running, the hammer body that hits real system hit real under sample (standard sample); Driving wheel as change gear and this legacy system is out of supply, and then this kinematic train does not operate and the action of another kinematic train, just and the hammer body that hits real system hits the sample (large-scale sample) under real, and show by switch board and to hit real result.
Two further technical solutions in addition of the present utility model: (one) is that its hammer lifting mechanism is different from prior art, and it comprises gear case, lifting handle, holder hammer plate.Its course of work is up time or inverse time liter, shake lifting handle, the gear shaft that is connected with lifting handle drives tooth bar and rises or descend, the shelves hammer plate that is provided with on the kinematic train during rising moves with chain, it is spacing to make hammer body have upper dead flake and shelves to hammer plate into shape, lifting handle has again and ends same finger setting, when hammer body falls to holder hammer plate, hits strength by hitting dig pass to test portion; (2) be to fall to hitting in fact, produce again resilience to hit accuracy real and influence examination sample compacting result for fear of hammer body along guide pole, the utility model is provided with shock attenuation device on the top of guide pole, this device is in box body, an end that comprises spring, spring is provided with sliding guide and is connected with guide pole, the other end is provided with adjusting screw, and box top is provided with the chute of the sliding guide that its lower end of slide bar is positioned at.Its course of work is, when hammer body falls behind down along guide pole, this moment, guide pole was given suffered surplus energy shock transfer that sliding guide, spring obtain damping, hammer body has lost resilience may.
The beneficial effects of the utility model
(1) reach dual-use by on-off gearshift, the apparatus structure compactness, and reduced the cost of specimen preparation, very easy to use.
(2) the hammer lifting mechanism simplicity of design is reasonable, and safe reliability is good.
(3) be provided with the guide pole shock attenuation device, avoided the backward down resilience of hammer body, guaranteed the reliability of specimen preparation data.
