Full-automatic magnetic suction type automatic compaction device for large-size sample

Abstract

The invention provides a full-automatic magnetic suction type automatic compaction device for a large-size sample. A hammer rod rotating auxiliary mechanism is arranged inside an upper hanging bracket; a hammer mechanism is arranged inside a sliding lower bracket; the hammer rod rotating auxiliary mechanism is connected with the hammer mechanism; the hammer mechanism is connected with a controllerthrough a line; and a lifting mechanism is connected with the hammer rod rotating auxiliary mechanism through a steel wire. The full-automatic magnetic suction type automatic compaction device for the large-size sample provided by the invention not only can reduce the soil splashing in the compaction process, reduce errors caused by non-vertical compaction during manual operation, greatly save manpower, and realize automation in the whole process to save the compaction time, but can also improve the compaction efficiency and quality through manual adjustment, further realize the standardization and the simplification, and improve the working efficiency.

Description

technical field [0001] The invention belongs to the field of geotechnical testing instruments, and in particular relates to a fully automatic magnetic suction type automatic compaction device for large-size samples. Background technique [0002] According to the specifications of geotechnical tests, all kinds of experiments on soil need to be compacted by compaction devices. Nowadays, in order to more compound the original conditions of the test, more and more large-scale test pieces are required, such as: large-scale frost heaving test The size of the machine test piece is a large-size test piece with a height of 1 meter and a diameter of 20 cm. In the compaction process of traditional large-scale specimens in the laboratory, the sample barrel cannot be fixed, resulting in instability. It also needs to be divided into layers of soil, and each layer of soil needs to be compacted. Due to the heavy hammer, excessive consumption physical strength, the hammer may not be guarant...

AI Technical Summary

Problems solved by technology

In the compaction process of traditional large-scale specimens in the laboratory, the sample barrel cannot be fixed, resulting in instability. It also needs to be divided into layers of soil, and each layer of soil needs to be compacted. Due to the heavy hammer, excessive consumption physical strength, the hammer may not be guaranteed to be lifted to a fixed height, and each time it is raised, the hammer may not be able to ensure that the hammer falls vertically, resulting in uneven compaction. The phenomenon of soil splashing is obvious with the increase of the number of layers, which seems to be time-consuming and labor-intensive, and there are many influencing factors in the actual process. The operation of different people will cause errors in the compaction conditions of the soil, which will affect the intensive reading of the test pieces, etc.
