The invention discloses an intelligent fault reporting and repairing control system. An information regulating module is used for establishing the time grade of the target fault equipment based on thetotal working time, the working time of the current date and the fault duration. A fault regulating module is used for determining the fault level of the target fault equipment based on the fault type. The damage regularization module is used for determining the damage level of the target fault equipment based on the total number of times of fault occurrence and the time interval between the lastfault and the fault. An intelligent control module is used to make fault reporting strategy for the target fault equipment. The invention collects the actual parameter information such as number of fault times, the fault time and the fault type of the fault equipment in real time to analyze and classify the fault of the equipment; according to the analysis results, different repair methods are selected to improve the overall and effective monitoring of the fault situation of the fault equipment in the working process, and the repair effect of the fault equipment, which is conducive to ensurethe maintenance efficiency of the fault equipment.

The invention discloses an automobile part maintenance pressing and fixing device and a pressing method thereof. The automobile part maintenance pressing and fixing device comprises a base plate. A lifting mechanism is arranged at the top end of the base plate. A lifting frame is mounted on the lifting mechanism. A working platform is fixedly mounted in the middle of the top end of the lifting frame. The top wall of an inner cavity of the lifting frame is symmetrically provided with electric telescopic devices. Telescopic rods of the electric telescopic devices penetrate through the top wall of the lifting frame to be fixedly connected with fine adjustment screw rods. The outer side of each telescopic rod is sleeved with a pressing plate matched with the working platform. Each fine adjustment screw rod is sleeved with a fine adjustment nut in a threaded connection mode. The outer side of each fine adjustment screw rod is sleeved with a preload spring matched with the corresponding pressing plate. According to the automobile part maintenance pressing and fixing device, a workpiece is placed on the working platform; the telescopic rods of the electric telescopic devices are retractedto descend the pressing plates, and the pressing plates are pressed down to fasten the workpiece; and finally, the fine adjustment screw rods are rotated to squeeze or release the preload springs toconduct local repressing or local releasing of the pressing plates, and accordingly, the position of the workpiece is finely adjusted to ensure the pressing quality.

The embodiment of the invention discloses a railway signal monitoring method and a railway signal monitoring system. The method comprises the following steps of: performing acquisition, convergence and format conversion on electrical characteristic information of equipment of the railway signal system and / or railway signal subsystem state information, adapting the information after the format conversion and a monitoring information processing module to form monitoring service data, and making a fault warning, early warning and statistical analysis interface according to the monitoring data after analysis and associated coupling. Because the embodiment adopts a uniform conversion format and is adapted to the information processing module of a fixed form, centralized monitoring of the equipment of the railway signal system is realized, the defects of decentralized management and decentralized maintenance of the railway signal system in the prior art are overcome, and a brand-new early warning mechanism and an intelligent expert diagnosis technique are provided. Because of high centralized degree, the embodiment optimizes the resource allocation of the railway signal monitoring system, and ensures corresponding maintenance efficiency at the same time of reducing the false alarm and missing alarm rate.

The invention provides a profile combination frame for a silo and a method for making a vertical shaft structure silo, belonging to the field of storage equipment, including a template assembly, an operation platform assembly, a hydraulic lifting assembly and a maintenance assembly. The hydraulic lifting assembly is used for For the lifting of the formwork assembly, the operation platform assembly includes an inner platform and an outer platform, which are used for operators or equipment to bind steel bars, pour concrete or place control equipment. The inner platform is arranged on the inner circle of the template assembly, and the outer platform On the outer ring of the formwork assembly, the curing assembly is arranged at the lower end of the outer platform, and water is sprayed outward to maintain the concrete. The invention improves work efficiency and reduces construction risk, adopts thin iron plates welded into inverted cones for overall construction, ensures the safety of the overall load-bearing support of the cone bucket construction, and makes the cone bucket appearance achieve the effect of fair-faced concrete.

The invention discloses a motor coil cutter and aims at providing a portable motor coil cutter. Key points of the technical solution are that the portable motor coil cutter comprises a cutting motor and further comprises a main support arm, wherein at least two auxiliary support arms onnected with the main support arm in a sliding manner, a first limiting part for locating the auxiliary support arms at specified positions, a rotation shaft rotationally connected with the main support arm and a placement shaft isolated from the rotation shaft are arranged on the main support arm; a clamping part for clamping a motor base is arranged on the auxiliary support arms; a lifting part for controlling the lifting of the placement shaft is arranged between the placement shaft and the rotation shaft; a placing part for placing a cutting motor is arranged on the side wall of the placement shaft; the cutting motor is connected with the placing part in a sliding manner and slides horizontally; a second limiting part for locating the cutting motor at the specified position is arranged on the placing part.

The invention provides a back supporting device for a large-caliber reflector. The supporting device comprises the large-caliber reflector, a lens back plate, a rotating shaft assembly, an adjusting connecting assembly, an adjusting rod assembly, a clamping block, a supporting plate and bolts. The rotating shaft assembly serves as a rotating shaft fulcrum of the large-caliber reflector, a spherical surface knuckle bearing of a standard component is adopted as a rotation main structure, the function of the spherical surface knuckle bearing and the function of a spherical hinge are the same, and the three translational motion freedom degrees of the reflector are restrained. A spiral driver is manually rotated to drive the adjusting connecting assembly to push the large-caliber reflector to do pitching and deflecting movement. After adjusting is finished, an adjusting nut is locked to limit the two rotating freedom degrees of the reflector. The face internal rotation freedom degree of the large-caliber reflector is restrained through the adjusting rod assembly. The back supporting device has the submicron-level positioning precision, can meet the requirements for various using angles and is simple in structure and accurate in positioning, pitching and deflecting two-dimensional precise adjustment of the online state and the offline state is achieved, and the designing cost and the manufacturing cost are reduced.
