A method of producing an object by means of additive manufacturing on a build surface of a build plate using such an apparatus is also provided.

The invention discloses a wind shield transportation support for paint spraying and relates to the technical field of a transportation support. The support is characterized in that the support comprises a sliding frame and a lower frame, wherein the sliding frame is located on an upper side of the lower frame and connected with the lower frame through a sliding mechanism, a sliding device is arranged on a lower side of the lower frame, the lower frame is fixedly connected with the sliding device, an inserting device is arranged on one side of an upper end of the sliding frame and comprises a double-head bolt inserted into the sliding frame, and two ends of the double-head bolt are not provided with threads and are rotationally connected with the sliding frame. The support is advantaged inthat a wind shield is lifted up through connecting plugs and slides to a proper position to be aired, the construction site is saved, the continuous work can be achieved, and a phenomenon of mistakenwork in the airing process is avoided.

The invention discloses a method for quickly detecting the remaining usage times of a battery, and relates to the technical field of batteries. The method is based on the relationship between the internal resistance of the battery and the number of cycles so that the number of cycles corresponding to the internal resistance of the battery can be deduced according to the measured internal resistance of the battery. The method includes the following steps: A. Measure the same model at the same room temperature The internal resistance of the battery under different cycle times of the battery, and make a graph of the relationship between the internal resistance and the cycle number of the battery; B. Divide the above graph into several stages and measure the internal resistance of the same type of battery used C. Judging the corresponding stage of the battery according to the internal resistance measured in the previous step; D. The number of cycles and the remaining number of cycles of the battery can be quickly detected according to the stage of the battery. . The invention has the advantage of high reliability, and is especially suitable for testing batteries during mass production or use.

The invention provides a cable-stayed suspension combined suspending method for cable protection in gallery inspection, belonging to the technical fields of equipment inspection and overhaul. The suspending method mainly comprises the following steps of: machining lifting lugs, manufacturing and installing a tensile supporting frame, and fixing and suspending a chain block; releasing a cable, connecting and adjusting; and pulling the cable out of a bridge frame and restoring. In the invention, complex processes such as removing the used cable from an electricity utilization site, drawing out, putting in, wiring, checking and the like are avoided, influence from the used cable when a truss is removed is effectively overcome, hardly predicated hidden dangers appearing after the cable is cut off are avoided, the construction cost of an overhaul or technical modification project is reduced, the overhaul or technical modification construction period is shortened, and a new method for effectively solving the problem of overhaul or technical modification for an entire removing gallery overspan building in a plant area is provided. The method provided by the invention has the advantages of capability of operating in advance, safety and reliability, high overhaul work efficiency, high economic benefit and the like.
