Embodiment Construction
[0028] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0029] like Figure 1-6 As shown, a concrete slump detection device includes a base plate 1, a mounting frame 2 arranged on the base plate 1, a lifting mechanism 4 connected to the mounting frame 2, and a measuring mechanism 5 arranged on the upper side of the base plate 1. The lower end of the mechanism 4 is connected with an axially vertical slump tube 3 , the diameter of the upper round opening of the slump tube 3 is smaller than that of the lower end round opening, and the lifting mechanism 4 adjusts the vertical position of the slump tube 3 and when it falls to the bottom, the slump tube 3 The circumference of the lower end of the base plate 1 is attached to the upper end surface of the base plate 1. The measuring mechanism 5 includes a vertical height scale 502 connected to the base plate 1 and a horizontal height scale 501. Th...

The invention discloses a concrete slump detection device, and relates to the field of concrete detection equipment. At present, most concrete slump detection devices adopt manual measurement, the perpendicularity between two straight rulers is difficult to guarantee by the measurement mode, the measurement precision is low, and the two straight rulers are separated from a slump cylinder and are often lost. The device comprises a bottom plate, a mounting frame, a lifting mechanism and a measuring mechanism, the lower end of the lifting mechanism is connected with the slump cylinder, the measuring mechanism comprises a vertical height scale and a horizontal height ruler, the ruler horizontally points to the slump cylinder and slides in the pointing direction, and the ruler can vertically slide and be fixed along the scale. The lifting mechanism adopts a rack capable of sliding vertically and a gear meshed with the rack, and the gear is connected with a hand wheel through a central gearshaft. When the device is used for measuring, the ruler and the scale are always kept in a vertical state, the use is convenient, the measuring precision is improved, the ruler and the scale are integrated with the slump cylinder and are not easy to lose, and the lifting mechanism is convenient to operate.
Description
technical field [0001] The invention relates to the field of concrete detection equipment, in particular to a concrete slump detection device. Background technique [0002] The slump is an index for testing the workability of concrete. The conventional slump testing method is generally: use a trumpet-shaped slump bucket with an upper mouth of 100mm, a lower mouth of 200mm, and a height of 300mm to fill the concrete and then compact it and pull it out. , The concrete collapses due to its own weight, and the height of the highest point of the concrete after the collapse is subtracted from the barrel height (300mm). This detection method requires a slump bucket, a spirit level, and a measuring tape to be used together, and the operation is not easy. [0003] When testing the slump, first place the slump cylinder on a flat ground, and the inspector steps on the two pedals with both feet to make the pedals firmly on the ground; then place the funnel on the top of the slump cylin...
