The invention relates to the technical field of cement production and manufacturing, aims at solving the problems that an existing grinding system is single in function and cannot have multiple cement grinding processes at the same time, and provides a composite multi-process cement grinding system and process and a cement production method. Wherein the composite multi-process cement grinding system comprises a roller press grinding system and a ball mill grinding system, and the composite multi-process cement grinding process comprises three grinding processes, namely a combined grinding process, a semi-final grinding process and a final grinding process; the cement production method comprises the following steps: separately grinding clinker and a mixed material by using two sets of cement grinding systems, and then mixing by using a mixing system to obtain a finished product. According to the invention, the limitation of a single grinding system is broken through, the operability of the system is improved through an ingenious switching means, and the advantages and functions of production through one system and coexistence of multiple technological processes are realized.

The invention relates to the technical field of current sensors, in particular to a double-air-gap high-precision high-range current sensor which comprises two Hall chips and an MCU controller, the two Hall chips are used for outputting magnetic field signals into two paths of electric signals, the MCU controller is used for collecting and processing output signals of the Hall chips, and the MCU controller is used for controlling the Hall chips to output the output signals. Averaging the output signals of the two paths of Hall chips; and by adopting the design of averaging output of the two Hall chips, the accuracy and the stability of measurement can be improved. By averaging the output signals of the two Hall chips, measurement errors caused by factors such as errors and temperature drift of the chips can be reduced; the double-air-gap high-precision high-range current sensor provided by the invention can maintain good performance when being influenced by external temperature and humidity, and solves the technical problem that the accuracy and stability of a double-air-gap current sensor in the prior art become poor due to the fact that the double-air-gap current sensor is easily influenced by external temperature and humidity.

The invention relates to the technical field of grab bucket equipment, and discloses a hydraulic grab bucket control system for movement of a water conservancy cleaning robot, which comprises a frame body, a partition plate is fixedly arranged in the middle of the frame body, a hydraulic assembly is fixedly arranged at the upper end of the frame body, and two groups of upper hydraulic cylinders are fixedly arranged on the inner wall of the upper side of the frame body; and two sets of lower hydraulic cylinders are rotationally arranged on the lower sides of telescopic rods of the two sets of upper hydraulic cylinders, two sets of grab bucket assemblies are arranged on the positions, close to the front side and the rear side, of the lower side of the frame body, two guide wheel sets are fixedly installed at the two ends of the frame body correspondingly, and each hydraulic assembly comprises a lower box body fixedly arranged at the upper end of the frame body. According to the grab bucket hydraulic control system for movement of the water conservancy trash removal robot, through overall cooperative use, the characteristics of high synchronous operation precision, simple and convenient operation and control and high efficiency can be completed, two sets of lower hydraulic cylinders on the same side are independently controlled, operation and control can be more flexible, and trash grabbing work can be efficiently carried out.

The invention discloses an RGV (Rail Guided Vehicle) crane trolley for assembling a railway freight car body, and belongs to the technical field of railway freight car assembling production. The RGV lifting trolley comprises a double-beam bridge type travelling crane, an RGV lifting trolley, a hydraulic control system, an electrical guidance control cabinet, a tower type multi-section telescopic lifting device, a rotary cross beam lifting appliance assembly, a trolley body side wall storage rack and a trolley body end wall storage rack. According to the control system, the RGV is used for hoisting the operation vehicle, the guidance technology is applied to improve the control system, optimize the process and program design, so that the operation and storage of products at different point positions are accurately completed, a manual and wireless combined mode is adopted for control, and the control operation is more convenient and flexible. Due to the fact that hoisting automation of the large-scale assembly parts is achieved, the assembly production time can be greatly shortened, manpower resources are saved, and the production efficiency is effectively improved.
