The invention discloses an automatic crushing equipment for the production of sulfate-resistant cement. The automatic crushing equipment for the production of sulfate-resistant cement comprises a frame, a rotary hammer assembly, and an impact plate assembly. Material inlet, below the material inlet is a semi-cylindrical and hollowed-out discharge cage, in which a plurality of rotary hammer assemblies are coaxially arranged, and adjacent rotary hammer assemblies pass through the main shaft In series, one end of the main shaft is connected to one side of the frame through a bearing, and the other end is connected to the frame through a power-receiving axial assembly; an impact plate assembly is provided on the side above the rotary hammer assembly that is staggered from the feed port; A bead is provided below the impact plate assembly, and the bead is spaced a certain distance from the edge of the rotary hammer assembly. Compared with the prior art, the present invention is suitable for feeding different materials to ensure the stable shape of the discharge.

The invention discloses a reaction frame testing method for earth nail drawing tests. The reaction frame testing method is realized through a reaction frame consisting of a base and a stress support. The base is connected with the stress support through screws, and a bearing surface of the stress support can be guaranteed to be coaxial with an earth nail by adjusting the screws. A jack is mounted on the stress support to form a jack reaction system. During testing, the earth nail can be fixed with the jack after being lengthened, and perpendicular stress is guaranteed by adjusting the screws. By adjusting the screws between the stress support and the support, stress surface on the wall at any gradient can be adjusted optionally, the perpendicular stress of the earth nail can be guaranteed, and testing speed and testing quality of the earth nail can be improved greatly.

The invention discloses a container overloading and unbalanced loading detection and protection system and method, and a reach stacker, and relates to the field of container overloading and unbalancedloading detection and protection devices and methods. The container overloading and unbalanced loading detection and protection system comprises four weighing sensors mounted in a main body crossbeam, an electric control cabinet, a display module, a printing terminal, an alarming device and an upper computer, wherein the electric control cabinet is integrated with an A / D conversion module, a signal amplification module, a data processing module and a transmission module, and the display module, the printing terminal, the alarming device and the upper computer are mounted in a cab. Weight signals collected by the weighing sensors are sent to the electric control cabinet, result data processed by the electric control cabinet are sent to the display module through the transmission module tobe displayed, sent to the printing terminal to be printed, sent to the alarming device for pre-warning and sent to the upper computer to be shared. In order to overcome the defects of inconvenience and inaccuracy during overloading and unbalanced loading weighing of a container in the prior art, the rapid and accurate container overloading and unbalanced loading detection and protection system andmethod, and the reach stacker are provided, and the container overloading and unbalanced loading limiting case can be alarmed, displayed and recorded in real time.

A floor-standing brake master cylinder performance test device, including an air source system, a fixed base, an adjustable support and a pressure rod mechanism, the adjustable support is arranged on the fixed base, and the adjustable support is equipped with a brake master cylinder. The pressure rod mechanism can be rotatably installed on the top surface of the fixed base. The center of its rotating shaft overlaps with the center of the pedal rotating shaft of the master cylinder. The suspender is installed with a roller against the pedal force sensor, the central axis of the bracket suspender is perpendicular to the upper surface of the pedal force sensor, a displacement sensor is fixed on the side of the adjustable support, and the displacement sensor is connected with the end of the pedal by a stay wire. The invention also discloses a floor type brake master cylinder performance test method, through the displacement sensor test and calculation, can accurately calculate and obtain the pedal angular travel amount, which is not directly related to the starting point of the displacement sensor pull wire, and has strong applicability.
