Background technology
At present, the additional mass test is used for the construction testing of on-the-spot dam, roadbed, ground, and the check point general random is taken a sample test; Because enrockment rolls body and has the advantages that material particle size is big, bed thickness is big, speed of application is fast; General traditional excavation hole survey method, boring nucleon density method all difficulty carry out, the normal small blocks (25kg) of being convenient to a dead lift that adopts of current additional mass test adopts artificial ramming during exciting; A test job of every completion needs 7 people; Cost of labor is high, inefficiency, wastes time and energy, so prior art still is not ideal enough.
Summary of the invention
The purpose of the utility model is: provide a kind of carrying, lifting, stacking, employing permanent-magnetic switching simple in structure, that be convenient to transport safely, can make things convenient for mass to carry out the structural design of quick exciting, realized the semi-mechanization of execute-in-place; Significantly reduce a kind of additional mass device that is used to test rockfill density of cost of labor and labour intensity, to overcome the deficiency of prior art.
The utility model is to constitute like this: a kind of additional mass device that is used to test rockfill density; Comprise the hold-down support that is provided with in the boxcar and on rockfill to be measured, be placed with additional mass; The top of hold-down support is provided with the lifting pivot arm that can move horizontally; The lifting pivot arm is provided with and can lets the type groove of pulley move left and right, is connected with the bottle gouard moved by hands that can lift additional mass or vibrator on the pulley, and the permanent magnetism absorption switch of may command vibrator work is installed on vibrator; Be placed with additional mass on vibrator and the rockfill and be connected, additional mass is connected through lead with tester on being arranged on lorry.
Additional mass is made up of additional mass base plate and 4～10 stacking blocks.
Additional mass base plate and stacking block are provided with can prevent sliding stop and projection that plugs together each other and groove.
On hold-down support, be welded with center rest.
Owing to adopted technique scheme; At first drive lorry to rockfill place to be measured; To prevent that through the lifting pivot arm that is provided with onboard additional mass onboard is transported to the rockfill top; And then vibrator is lifted on the bottle gouard moved by hands, give the vibratory output of additional mass one definite form through utilizing vibrator with size, utilize tester to measure data; Therefore; The utility model compared with prior art, the advantage of the carrying that the utility model not only has is simple in structure, be convenient to transport safely, can make things convenient for mass, lifting, stacking, but also have adopt permanent-magnetic switching carry out quick exciting structural design, realized execute-in-place semi-mechanization, significantly reduce advantages such as cost of labor and labour intensity.
