And the center of the coordinated adjustment support platform coincides with the axis of the slump bucket; Stop the frame car at a suitable location - fix the support platform - level the foot screw screw - long press the down button to lower the slump bucket to the dial and fix it - turn on the vibration mode - fill the concrete in three times and tamp it , Filling——Turn off the vibration mode——Long press the lift button to raise the slump bucket to an appropriate height at a constant speed——Observe the reading on the dial to get the slump expansion. 9. A method for carrying out a concrete emptying test using a mobile leveling type high-precision testing device, characterized in that: the device is equipped with a frame platform on the frame vehicle, and a supporting platform is arranged on the platform of the frame platform; The support platform is set in the shape of a disc, and the support platform is horizontally arranged on the table surface of the frame platform, a level is arranged in the center of the support platform, and the slump expansion degree dial is marked on the table surface of the support platform; A left lifting track and a right lifting track are arranged on the frame platform in the extension direction of the support platform diameter; a fixed rod is installed horizontally between the left lifting track and the right lifting track, and the center of the fixed rod is fixedly connected with a slump bucket; The slump barrel is set as a variable-diameter cone structure with a high cylinder and a short cylinder coaxially connected, and the high cylinder is set as a high cylinder in the shape of a variable-diameter cone with a wide mouth at the bottom and a narrow mouth at the top The short cylinder is set as a short cylinder in the shape of a variable-diameter cone with the lower mouth as the neck and the upper mouth as the wide mouth. The necking of the high cylinder and the necking of the short cylinder are connected with the caliber to form a whole. Slump barrel; the height of the high cylinder is greater than that of the short cylinder, and the fixing rod is fixedly connected to the wall of the high cylinder; The left lifting track is equipped with a left lifting track, and the right lifting track is equipped with a right lifting track; The left lifting track and the right lifting track are driven by the left and right synchronous track motors at the bottom; The left hoisting track and the right hoisting track are synchronously hoisted or descended; The left lifting track is connected to the left end of the fixed rod through the left control seat; The right lifting track is connected to the right end of the fixed rod through the right control seat; The left and right control seats are evenly equipped with left and right synchronous rotating motors and vibration motors, The left and right synchronous rotating motor drives the fixed rod to rotate, and the left and right synchronous vibration motor transmits the vibration of the fixed rod; The crawler motor, rotating motor and vibrating motor are all connected to the controller, and the controller is fixedly connected to the table of the frame table. The controller is equipped with stop button, lifting button, lowering button, rotation button and vibration button; The controller is connected to the power supply, and the power supply controls and drives the crawler motor, rotating motor and vibration motor through the controller; The frame table is provided with a scale base, the scale base is equipped with a scale frame, and the scale frame is equipped with a folding length scale; There are adjustment seats distributed on the table surface of the frame table around the support platform. The foot screw screws are screwed on the adjustment seats and connected to the side wall of the support platform. The circumferentially distributed foot screw screws fix the support platform horizontally. And the center of the coordinated adjustment support platform coincides with the axis of the slump bucket; Stop the frame car in a suitable place - fix the universal wheel - fix the support plate - level the foot screw - press the "rotation key" to turn the small mouth of the slump bucket down - long press the "down key" to slump Lower the slump bucket to the dial and fix it—turn on the vibration mode—fill the concrete three times and tamp it, fill it up—turn off the vibration mode—long press the "lift button" to raise the slump bucket to an appropriate height at a constant speed— Timing, stop timing when it is empty, the total time is the concrete emptying degree.
