The invention discloses a method for automatically grabbing blast furnace water slag through a travelling crane. The method comprises the following steps that (1) an automatic slag grabbing system isbuilt up; (2) parameters are set; and (3) slag grabbing is achieved, wherein when a grab bucket is in contact with the water slag in one slag flushing pool, a controller records the numerical value ofan absolute value encoder at this moment, the height, namely, the height of the water slag in grabbing units, of the bottom of the grab bucket, is obtained, the water slag is grabbed, the controllercontrols the grabbing bucket to sequentially grab the water slag in the k*j grabbing units in the slag flushing unit, operation is carried out by multiple turns till all the water slag in the slag flushing pool is grabbed, and then the water slag in the next slag flushing pool is grabbed. According to the method, a weight sensor is arranged on a steel wire rope, the absolute value encoder is arranged on a winding drum, the multiple slag flushing pools are numbered, each slag flushing pool is divided into the k*j grabbing units, and multi-turn slag grabbing is carried out on each slag flushingpool till all the slag is grabbed; and efficiency is high, manual operation is not needed, manpower is saved, and personal injuries are reduced.

The invention relates to an energy consumption information management method of a low-power consumption wide area network internet of things networking technology. The method comprises the following steps: the industrial data is managed through a networking way, wherein the networking comprises a sensing layer, a transmission layer and a service layer; inthe sensing layer, the field data detected by sensors in the industry is sent to field wireless modules; in the transmission layer, the field data is transmitted to Lora gateways through the field wireless modules and uploaded by the Lora gateway based on an IP address; in the service layer, the uploaded data is connected to monitor system hosts, a server and an upper data centre through a public network cable to perform the data processing, thereby performing the energy monitoring and management; and a terminal user can query the information through the service layer. A new low-power consumption and long-distance wireless network, namely Lora technology, is adopted, thereby satisfying the requirements of low cost, low power consumption and long distance of the industry, the electricity and like industries. The method is suitable for the requirement of setting data collection points in large scale in the industry, the electricity and the like.

The invention relates to a new energy automobile engine cylinder cover front-end steel jacket press-in machine which comprises a working table. A support I, a support II and a support III are sequentially arranged on the upper part of the working table from left to right; two vibrating plate I and vibrating plate II are arranged on the upper part of the support I; a product sorting device is arranged on the upper part of the support II; a press-in drive device is arranged on the upper part of the support III; a rotary feeding device is arranged on the left side of the lower part of the supportIII; a press-in execution device is arranged on the right side of the lower part of the support III; an X-direction moving module is arranged right under the support III; a steering module is arranged on the upper part of the X-direction moving module; and a positioning plate for bearing a cylinder cover is arranged on the upper part of the steering module. According to the new energy automobileengine cylinder cover front-end steel jacket press-in machine provided by the invention, different steel jackets are output through the two vibrating plates II, a pushing horizontal air cylinder pushes the steel jackets into the rotary feeding device, the rotary feeding device rotates the steel jackets to be right below the press-in execution device, and the press-in execution device presses the steel jackets into corresponding slot holes of the cylinder cover, so that manual loading and unloading are replaced, the cylinder cover pressing and sleeving efficiency and quality are improved, and the new energy automobile engine cylinder cover front-end steel jacket press-in machine has a favorable market application value.
