The invention relates to an installation device for prefabricated building components, comprising an assembly installation groove and a support support plate, the support support plate is movably arranged in the assembly installation groove, and one end of the support support plate is connected with several A rotating support column, on which a rotating rod is fixedly inserted; the present invention aims to provide a device for clamping, fixing and lifting the prefabricated building components during the installation process, specifically, in the prefabricated building prefabricated components During the component installation process, the equipment first clamps and fixes the prefabricated building components at the bottom, and then lifts the prefabricated building components to the corresponding installation position through the equipment, and finally the equipment can carry the prefabricated building components. Rotate, and make the prefabricated building components in a vertical state; at the same time, the device can also achieve the effect of rapid positioning, which can effectively improve work efficiency.

The invention discloses a waterproof heat-conducting lithium battery pack case, which comprises an outer case and an outer case cover arranged at the upper end of the outer case, wherein an inner caseand a cold water tank are arranged one inner side of the outer case respectively, the bottom end of the inner case is communicated with the upper end of the cold water tank, the inner case and the cold water tank are welded through a stainless steel plate, one side of the cold water tank is communicated with a cold water storage container through a water duct on which a water pump is arranged, and an overflow pipe communicated with the cold water tank is arranged on one side of the cold water storage container. The waterproof heat-conducting lithium battery pack case is reasonable in design;a lithium battery module is arranged in the inner case and the inner case is arranged in the outer case, so that a better protection and waterproof effect on the lithium battery module is achieved; the lithium battery module is placed between a mounting plate and a pressing plate through tightening bolts, so that a clamping and fixing function is realized, the lithium battery module stored at thebottom of a vehicle is prevented from swinging in a running process, and normal work of the lithium battery module is further ensured.

The invention provides a crankshaft polishing support device with a self-cleaning function, which comprises an upper support transverse plate, a support column, a lower support transverse plate, a mobile wheel, a fixed through hole, a clampable crankshaft fixed clamping seat structure, a filter adsorption scrap cleaning cover structure, a crankshaft grinding and trimming rod structure, a fixable oil pot air cylinder push rod ejector rod structure, a rear part protective baffle, amanual pushing handle, an anti-skid sleeve, a lifting control switch, a cleaning and dust collecting control switch,a first fixingseat, a lifting air cylinder, a movablesliding groove, a second fixing seat, and a magnet strip. According to the crankshaft polishing support device with the self-cleaning function,thearrangement of a waste collection box, a fixed inserting tube, a manual holding handle, a connecting rod, afile plate, a stainless steel bending strip, and abrush cleaning device are favorable for cleaning the bending portion of the crankshaft after the polishing is completed, the waste collection box is used for collecting, a good working environment is maintained while an unsuitable part is ground and trimmed with the file plate.

The invention discloses a chemical filtration device and a working method thereof. The chemical filtration device comprises a filtering flask body, a filtering funnel, a buffer flask, a vacuum pump and a fixing device, wherein a fixed area is formed on a bottom plate and used for forming a support for the lower part of the filtering flask body; the fixed area comprises a groove; an elastic annularbody is arranged in the groove; the bottom of the filtering flask body is placed in the elastic annular body; a rectangular frame is arranged at the outside of the elastic annular body; a through hole is formed in the rectangular frame; and a moving part is arranged in the through hole. When the filtering flask body is placed in the fixed area, the elastic annular body has a clamping and fixing effect on the filtering flask body, and can also have an elastic buffering effect on the filtering flask body; and in addition, the moving part can move to play an abutting effect on the elastic annular body, so the elastic annular body has a clamping and fixing effect on the flask body clamped and fixed inside.
