The invention relates to a high-degradation layered nickel-cobalt-manganese positive electrode material single-crystallization upgrading reconstruction method, which comprises the following steps: S1, discharging a waste ternary lithium ion battery, disassembling and crushing to obtain positive electrode powder; s2, mixing the obtained positive electrode powder and the selected molten salt according to a determined proportion, grinding by using a ball mill to ensure that the molten salt and the recycled powder are uniformly mixed, then performing a lithium supplementing process under a high-temperature condition, and meanwhile, effectively removing impurities such as a residual binder and a conductive agent in the positive electrode powder; the lithium supplement heating condition is that the temperature is raised to 600 DEG C, heat preservation is performed for 2 hours, then heat preservation is performed for 4-6 hours at 910-930 DEG C, the temperature raising speed is 4 DEG C / min, and the gas atmosphere is air. And S3, the sample after lithium supplementation is completed is subjected to heat treatment in the oxygen atmosphere, impurity phase structures possibly existing on the surfaces of particles are repaired, the electrochemical performance of the regenerated material is close to the performance of a commercial battery, meanwhile, due to the unique single-crystal structure, the structural stability of the regenerated material is greatly improved. The method can be applied to recovery of various ternary lithium ion battery positive electrode materials by simply adjusting the heating temperature and the heat preservation time, and has very high application value.

The utility model provides a kind of carrying power mechanical equipment belongs to rail train technical field, to solve the problem in prior art, through artificial overturning traction beam is not only inefficient, and process is complicated, and a large amount of manpower and time cost are wasted;Including the upright column connected with the end of manipulator, upright column bottom is equipped with crossbeam, the side of crossbeam is slidably connected with two clamps, two clamps are driven by being equipped with driving device on crossbeam;The opposite end of two clamps is equipped with clamping plate, clamping plate is rotatably connected with clamp by pivot, pivot is driven by being equipped with rotating device on clamp;In the utility model, the carrying power mechanical equipment can realize automatic grabbing, carrying and overturning function, effectively replaces the operation mode of artificial overturning traction beam. Improve the working efficiency of traction beam pressure test, reduce manual intervention, reduce manpower cost and labor intensity, avoid the possible mistake of artificial overturning, improve the safety and reliability of test process.

The present invention belongs to the field of supporting equipment for tunnel and pipe well excavation equipment, and particularly relates to a pipe joint anti-retreat device, which comprises an anti-retreat platform, which comprises a fixed part and a rotating part, and the rotating part is provided with more than two latches for inserting into grouting holes of the pipe joint to be stopped and cooperating with each other to hold the pipe joint, and each of the latches extends along the radial direction of the rotating part; or, the anti-retreat platform has only a fixed part, and a latch group is provided on the fixed part, and the number and relative position of the latch groups meet the requirement that when the pipe joint to be stopped is arranged at different angles, at least one latch of the latch group can be directly opposite to the grouting hole of the pipe joint to be stopped, and because the latch is inserted into the grouting hole of the pipe joint, no radial force is applied to the pipe joint, thereby not affecting the structural strength of the pipe joint, and at the same time, because the pipe joint generally has a grouting hole, the pipe joint anti-retreat device has higher versatility.
