Description

Technical Field

[0001] The utility model belongs to the field of testing machines, and in particular relates to a cement pressure testing machine. Background Art

[0002] Cement is a powdery hydraulic inorganic gelling material. It becomes a slurry after adding water and stirring. It can harden in the air or in water, and can firmly bond sand, stone and other materials together. The early mixture of lime and volcanic ash is very similar to the modern lime volcanic ash cement. It is used to bond concrete made of crushed stone. After hardening, the concrete not only has high strength, but also can resist the erosion of fresh water or salt water. For a long time, it has been used as an important cementing material and is widely used in civil construction, water conservancy, national defense and other projects. Cement is generally divided into general cement and special cement.

[0003] The authorization announcement number "CN218212393U" records that "it includes a fixing mechanism, an extrusion mechanism and an adjusting mechanism. The extrusion mechanism is fixed to the top of the fixing mechanism with the adjusting mechanism screwed inside. The fixing mechanism includes a fixing platform with a protective tube fixedly connected to the middle of the top. The extrusion mechanism includes a hydraulic cylinder fixed to the top of the fixing platform. The adjusting mechanism includes a bearing plate screwed to the top of the fixing platform. A threaded hole is opened in the middle of the top of the fixing platform along its vertical center line. The utility model drives the screw and the bearing plate to be screwed to a suitable height along the threaded hole by turning the knob, and then places cement on the top of the bearing plate. Then, the hydraulic cylinder drives the hydraulic rod and the extrusion head to move downward to extrude the cement. When the cement breaks, the protective tube is used to block the cement blocks that are splashed by the break, thereby enabling the cement pressure testing machine to reduce its test limitations and prevent cement from splashing after breaking."

[0004] The above patent prevents cement from splashing after breaking, but it is not convenient to clean the broken cement after each test is completed. It needs to be cleaned manually, thus reducing the efficiency of the experiment. Utility Model Content
