They are used to test the strength grade of mortar. When testing cement test blocks in railway engineering, the compressive strength and flexural strength of the cement test blocks are tested, which requires the use of pressure testing equipment.

[0003] In existing technologies, such as the Chinese patent application CN120489777A entitled "A Cement Strength Testing Device for Railway Engineering Based on Intelligent Sensors," the device includes a base, a platform fixedly connected to the top of the base, and an electric hydraulic cylinder fixedly connected to the top of the platform; an L-shaped rotating block; the bottom of the electric hydraulic cylinder is rotatably connected to the L-shaped rotating block via a rotating shaft; a fixing block is fixedly connected to the front right side of the L-shaped rotating block; the bottom of the fixing block is movably connected to the hydraulic block via a push block; the top of the hydraulic block is fixedly connected to the side of the electric hydraulic cylinder via a fixing block; the hydraulic block is fixedly connected to the hydraulic block via a hose; and a lifting block is movably connected to the top of the hydraulic block via a push block.

The opening and closing of the bottom of the aggregate inlet 211 can be controlled by moving the bottom sealing support plate 207 through the movement of the closed shell 201. After the inspection is completed, the cement block opens the aggregate inlet 211 as the bottom sealing support plate 207 moves, making it easy to fall into the aggregate drawer 210, which facilitates the cleaning and collection of broken cement blocks. The protective top cover 310 is connected to the mounting side plate 311 through the fastening bolts 312 and the fastening nuts 313, thereby closing the top of the closed shell 201. The protective top cover 310 presses on the top of the tempered glass 308, which is convenient for the use of the clip. The connecting plate 307 limits and fixes the tempered glass 308, making it easy to open and replace it in case of subsequent damage. The viewing window 306 facilitates observation of the internal cement block inspection. The double-layered tempered glass 308 not only facilitates viewing but also improves the overall protective effect. The sealing door plate 301 facilitates the closure of the movable opening 202, making it easy to maintain the closed protective state of the closed shell 201.
