Description

Technical Field

[0001] The present invention relates to the technical field of civil engineering construction, and particularly to a hoisting device for rock wool sandwich panels. Background Art

[0002] The rock wool sandwich panel is a sandwich panel made of rock wool as raw material. The rock wool sandwich panel gives full play to the unique properties of the rock wool core material and has remarkable effects in aspects such as fire prevention, heat insulation, sound absorption and noise reduction. It is commonly used as the exterior wall panel of steel structure workshops; during the construction of the exterior wall of steel structure workshops, it is often necessary to lift and install the rock wool sandwich panels; however, the traditional hoisting method is that on-site operators make simple lifting tools for hoisting, and the fixing is done by drilling holes with screws. When constructing the exterior facade, drilling holes for hoisting not only makes it difficult to remove the fixture after the wall panel is installed, posing serious safety hazards, but also there is a risk of later leakage after drilling the screws, reducing the quality standard and increasing the maintenance cost.

[0033] When the device is in use, first stand up the rock wool sandwich panel, and adjust the position of the adsorption and clamping mechanism at the lower part according to the width of the rock wool sandwich panel. When adjusting, just pull the C-shaped pull handle 26 outward, so that the positioning block 24 disengages from the longitudinal clamping hole 2202 and displaces into the vertical sliding hole 2201, and then pull the sliding rod 22 up or down. When the adsorption and clamping mechanism at the lower part is adjusted to the appropriate position, release the C-shaped pull handle 26. Under the elastic force of the spring 25, the positioning block 24 is clamped into the longitudinal clamping hole 2202 at the corresponding height; then adjust the positions of the front and rear groups of adsorption and clamping mechanisms. When adjusting, rotate the two rotating handles II 19 respectively, and drive the two I-shaped hanging brackets 20 to move towards or away from each other through the screws II 18 respectively, so as to realize the position adjustment of the adsorption and clamping mechanism at the bottom of the I-shaped hanging bracket 20; then drive the eight electromagnetic chucks 27 to move towards each other through the rotating handle I 9 to clamp the left and right end faces of the rock wool sandwich panel, and then energize the eight electromagnetic chucks 27, and the two relatively arranged electromagnetic chucks 27 attract each other to further improve the clamping stability; then put the two elastic bands 31 on the front and rear ends of the rock wool sandwich panel respectively, and the two elastic bands 31 can limit the front and rear displacement of the rock wool sandwich panel to a certain extent; finally, pass the other end of the binding band 33 through the bottom of the rock wool sandwich panel and fix it on the C-shaped bracket 34, which can limit the downward displacement of the rock wool sandwich panel, and then connect the lifting device through the lifting lug 3, and lift the rock wool sandwich panel through this device.
