The invention discloses an online ash removal device of an intelligent fan rotor. The online ash removal device comprises a liquid source, a compressed gas source, an electrical control system, a gas-liquid control cabinet, a control cable and a gas-liquid composite nozzle; the liquid source and the compressed gas source have certain pressure; the pressure of the compressed gas source is higher than that of the liquid source; a gas inlet and a liquid inlet are formed in the gas-liquid composite nozzle; the liquid source and the compressed gas source communicate with the liquid inlet and the gas inlet of the gas-liquid composite nozzle respectively through pipelines; the electrical control system and the gas-liquid control cabinet are used for controlling the compressed gas source and the liquid source respectively; and the acute angle formed by the axis of the gas inlet of the gas-liquid composite nozzle and the axis of the liquid inlet is theta1. The online ash removal device can realize the effects of preventing the fan rotor from accumulating ash and timely cleaning ash adhering to the surface, online ash removal under the conditions that the fan rotor does not stall and equipment is not shut down can be realized, and the use cycle of the fan rotor is prolonged.

The invention discloses a construction method for breaking and removing a monolithic track bed in a subway operation line tunnel. The construction method comprises the following steps that 1, first-stage concrete breaking and removing is conducted; 2, second-stage concrete breaking and removing is conducted, temporary steel sleeper transition line is installed, passage is recovered; 3, third-stage concrete breaking and removing is conducted. According to the construction method, a laid track bed is cut through low-noise rope saws and wall saws, cut laid slabs are lifted and conveyed through researched cantilever cranes in a subway tunnel, and then the laid monolithic track bed is changed. By the adoption of the construction method, noise is low, the operation line does not stop during construction, safety and reliability are achieved, and the requirements for urban civil construction, operation line transportation, operation line safety and construction efficiency are met.

The invention discloses an automatic production line. The automatic production line comprises a loading elevator, a connecting table assembly line for conveying products or product parts and a lifting backflow machine, which are connected in sequence, wherein the connecting table assembly line includes multiple connecting tables connected in sequence; the connecting tables include fixed frames, first rail devices mounted on the fixed frames for conveying the products or the product parts in a normal mode, and moving plates for placing the products or the product parts; feed sides and discharge sides are respectively arranged on two sides of the fixed frames; and the first rail devices include first upper circulating rail modules for conveying the moving plates placed with the products or the product parts from the feed sides to the discharge sides, and first lower circulating rail modules for circularly returning the moving plates from the discharge sides to the feed sides. The invention further discloses an operation method of the automatic production line. The automatic production line can enable the moving plates to be recycled on the circulating rail modules, and is high in production efficiency and automation degree.

The invention relates to a large double fine-blanking machine linkage production line and a working method thereof. The defect that an existing fine-blanking machine can not machine a product with the complex structure and the irregular blanking shape and thickness is overcome. The large double fine-blanking machine linkage production line comprises two fine-blanking machines with the same level, each fine-blanking machine is provided with an oil control loop and an electric control loop, the first fine-blanking machine serves as first-order machining equipment, the second fine-blanking machine serves as tail-order machining equipment, the first fine-blanking machine is connected with a material levelling machine in a butt-joint mode through a material channel, and the two fine-blanking machines are connected through a transition bridge frame type material conveying coordination device. According to the large double fine-blanking machine linkage production line and the working method thereof, the two fine-blanking machines cooperate with each other to complete machining of a product, the machining steps of the product are sequentially conducted, and then machining of the product with the complex structure and the irregular blanking shape and thickness is completed; the first-order machining time and the tail-order machining time has a difference, the difference is coordinated through the transition bridge frame type material conveying coordination device, therefore, the primary working time difference of the two fine-blanking machines is compensated, and then continuous running of the product is achieved without influencing product machining.
