According to the industrial solid waste recycling and reusing treatment system, the existing problems that when an existing heat preservation pipe is recycled, and the locking effect of the heat preservation pipe is poor, so that the heat preservation pipe rotates during cutting action, the cutting effect of a rock wool layer is poor, recycling of the rock wool layer is affected, a steel pipe is damaged when a cutting machine cuts the heat preservation pipe, and the rock wool layer isnot cut thoroughly and needs to be completely cut manually by using a cutter and the like are solved.

The present application provides a compensation mechanism with controllable deflection and crack tip blunt expansion radius, which relates to the technical field of precision molding. The compensation mechanism includes a rod unit and a ball head unit. The rod unit consists of a first rod and a second Two rods are connected; the ball head unit includes a universal rotatable ball head, a ball head push rod and a spring; the compensation mechanism includes a protrusion, and the end of the protrusion is a hemispherical and circular cylinder The body is integrated, and the connection between the hemispherical and circular cylinder is equipped with a universal rotatable ball fulcrum, which solves the problem that the applied load cannot effectively control the deflection of the pipe material end during the dynamic separation process of the metal pipe material. The microscopic manifestation of the problem is that the change of the passivation radius of the crack tip is uncontrollable. Before the crack propagates to the inner wall of the pipe material, the problem of instability and instantaneous failure occurs due to reaching the critical passivation radius of the crack tip in advance.

The invention relates to hanging equipment with stable fixation and for lifting plates of buildings. The hanging equipment comprises an installing plate and a first rope, wherein an installing block is arranged at the left side of the upper end of the installing plate, and a first auxiliary supporting rod is arranged at the upper end of the installing block; a cross rod is embedded at the right side of the installing plate, and a main supporting frame is connected at the upper end of the cross rod; a second auxiliary supporting rod is arranged at the upper end of the right side of the main supporting frame, and a rope control box is fixed at the upper end of the left side of the main supporting frame. The hanging equipment has the beneficial effects that by a sliding plate, the hanging equipment can slide towards the left side on an installing frame, then the first rope is driven to slide towards the left side, when the plates are lifted to the upper end, the plates can be driven to the left side of the equipment by utilizing the sliding plate, then the plates at the outer side enter a building room, and the step of pulling the plates into the room by means of hands of workers whenthe plates are lifted is omitted, so that not only can the workload of the workers be reduced, but also the danger caused by manually pulling the plates into the room can be avoided.

The invention discloses a device for dynamically identifying the network equipment topology of an intelligent substation based on MAC address matching. The device comprises a dynamic network topology identifier; the dynamic network topology identifier comprises a dynamic network topology configurator, a dynamic network topology analyzer, a dynamic network topology graphical device and a dynamic network topology updater; the dynamic network topology identifier is connected with a control hall central host of the substation; a control hall multi-media display screen displays the topological state of the whole substation network system; the control hall central host is connected with a mobile packet wireless communication device through a control hall wireless communication device; and real-time dynamic graphical query of the network equipment topology can be realized through a mobile packet. By means of the device disclosed by the invention, the topological graph of an online switch and the states of various ports in an intelligent substation network can be monitored intuitively in real time; the topological relationship of equipment can be queried on the scene in real time through the mobile packet; therefore, remote judgement and prediction on equipment failure can be realized; and the efficiency is increased.

The invention discloses an extensible building steel structure, which comprises X-shaped components.
