Embodiment Construction

[0049] The following description serves to disclose the present invention to enable those skilled in the art to carry out the present invention. The preferred embodiments described below are only examples, and those skilled in the art can devise other obvious variations.

[0050] Such as figure 1 Shown, a kind of municipal engineering concrete slump test device comprises,

[0051] frame;

[0052] Test bench 1, set on the rack;

[0053] The mold 2 is movably placed on the test bench 1, the mold 2 is in the shape of a cone, and the test bench 1 and the mold 2 are combined to form a barrel body with a conical cavity, and the barrel body is used for pouring concrete;

[0054] The mold opening device 3 is arranged on the frame, the output end of the mold opening device 3 is connected to the mold 2 in transmission, and the mold opening device 3 is used to drive the mold 2 away from the test bench 1, so that the concrete on the test bench 1 is exposed;

[0055] The detection devi...

Abstract

The invention relates to the field of municipal engineering equipment, in particular to a municipal engineering concrete slump testing device which comprises a rack, a test board, a mold, an opening device and a detection device. The test board is in a disc shape, the mold comprises a plurality of mold modules in the same shape, the mold modules are evenly distributed around the test board, the bottom ends of the mold modules are rotationally connected with the test board, the output ends of the mold opening devices are in transmission connection with the mold modules, and the detection ends of the detection devices face the joint of every two adjacent mold modules. According to the technical scheme, the problem that when a worker cleans existing concrete slump detection equipment, the armof the worker is located under a suspended mechanical part, and personal injuries are likely to be caused during mechanical failures is solved.

Description

technical field [0001] The invention relates to the field of municipal engineering equipment, in particular to a municipal engineering concrete slump testing device. Background technique [0002] The slump is the method and indicator for the determination of the workability of concrete. In the construction site and laboratory, the fluidity of the mixture is usually measured by the slump test, and the cohesion and water retention are evaluated by visual experience. The slump is a quantitative index to measure its level, which is used to judge whether the construction can proceed normally. [0003] Test method of slump: use a trumpet-shaped slump barrel with an upper mouth of 100mm, a lower mouth of 200mm, and a height of 300mm, pour concrete into it and fill it three times. Hit 25 times, after tamping, smooth. Then pull up the barrel, the concrete will slump due to its own weight, subtract the height of the highest point of the concrete after the barrel height (300mm) from ...
