Embodiment
As shown in Figure 2, this photo-electric concrete slump tester mainly comprises slump cone 1, base plate 2, jacking sleeve 3, base sleeve 4, pole 5, hoisting gear.
The internal diameter of described jacking sleeve 3 is greater than the external diameter of slump cone 1.On the inside surface of jacking sleeve 3, be provided with infrared transmitter 31, infrared receiver 32, infrared transmitter 31 is arranged on same level position with infrared receiver 32.On the outside surface of jacking sleeve 3, be provided with the infrared receiver prompting device 33 that sends information when infrared receiver receives infrared ray, this infrared receiver prompting device 33 is connected with infrared receiver 32.The outside surface of jacking sleeve 3 is provided with one section of external thread 34.
Jacking sleeve 3 is connected by the internal thread 41 of external thread 34 and a base sleeve 4.
Described base sleeve 4 is packed on base plate 2.
Described pole 5 vertically arranges, and pole 5 is positioned at outside base sleeve 4, is provided with along the vertical direction the scale 51 for indicating height on pole 5; And this scale 51 is provided with the infrared ray elemental height mark 52 corresponding with the initial position of infrared transmitter 31, infrared receiver 32.
Before measurement, first determine the distance L 1 of infrared ray to jacking sleeve 3 tops by scale.When measurement, slump cone 1 is filled concrete, then slump cone 1 is mentioned to Control Measures for Concrete Slump; Open infrared transmitter 31, infrared receiver 32 on jacking sleeve 3; Infrared transmitter 31 is sent infrared ray, owing to being blocked by concrete, so infrared receiver 32 does not receive infrared ray at the beginning; Then rotation and lifting sleeve 3, jacking sleeve 3 rises gradually, and infrared transmitter 31, infrared receiver 32 also rise thereupon gradually, and the infrared ray that infrared transmitter 31 is sent rises thereupon; In the time that infrared ray rises to concrete top peak, then rotate a little jacking sleeve 3, infrared ray is no longer subject to concrete blocking-up, infrared receiver 32 can receive, thereby trigger infrared receiver prompting device 33 and send prompting, operator knows, jacking sleeve 3 stops operating.Then determine the top height of jacking sleeve 3 in this critical point place, again according to previously recording the distance L 1 of infrared ray to jacking sleeve 3 tops, can draw the residing height of infrared ray, i.e. concrete height after caving in, thus can calculate the slump according to the height of slump cone.
