The invention discloses a self-propelled tunnel lining concrete curing stand. The stand comprises a tunnel body and a stand, rails are fixedly mounted on two sides of the bottom face in the tunnel body, and a rotation shaft is rotatably connected to the lower surface of the stand through a supporting base; a driven gear is fixedly connected to the center of the outer surface of the rotation shaft, a driving gear is meshed to the upper surface of the driven gear, and a gear motor is fixedly connected to the driving gear through a shaft; the gear motor is fixedly mounted on the upper surface of the stand, oblate holes are formed in the side faces of two ends of the rotation shaft, and an oblate shaft is connected in the oblate holes in a sliding mode; a positioning nut is connected to the outer surface of the oblate shaft in a threaded mode, idler wheels are fixedly connected to two ends of the oblate shaft, and the idler wheels are fixedly connected to the upper surfaces of the rails. The self-propelled tunnel lining concrete curing stand can improve the convenience of concrete curing greatly, guarantee the efficiency of concrete curing and lower costs.

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 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.
