The invention relates to a roof support process under a coal mine, in particular to fully mechanized mining face mining stopping support method. The problems that an existing fully mechanized mining face is high in mining stopping I-shaped steel support cost, large in labor intensity of workers and long in mining stopping support construction period, and top plate local breaking is prone to occurring are solved. According to the fully mechanized mining face mining stopping support method, anchor cables, anchor rods, metal nets, steel belts and combined anchor cable groups are adopted for combining support, the self-bearing capability of a bracket is matched, and mining stopping support is conducted; and the working face is divided into a frame dismantling channel, a bracket and mining stopping support combined support area and a natural caving area according to purposes after mining stopping to conduct top plate management during mining stopping, local support strengthening is conducted in a targeted mode, and I-shaped steel is replaced by the combined anchor cable groups, so that support is more timely, and the top plate separate layer phenomenon is avoided. Compared with existingmining stopping support, the material cost and manual consumption are greatly reduced, and the safety risk in construction is also reduced. The mining stopping support working period is shortened from 25 working days to 13 working days.

The invention discloses a laminating device for a protective film of an automobile door. The laminating device comprises a U-shaped laminating device body, wherein fixing clips for fixing the automobile door are arranged on the inner sides and at the tops of the two edges of the laminating device body respectively; each fixing clip comprises a bolt and a flexible pad positioned at the head of the bolt; the tails of the bolts penetrate out from the inner side of the laminating device body to the outer side; rollers are arranged on the inner sides and at the bottoms of the two edges of the laminating device body; the two ends of the rollers are mounted on the two edges of the U-shaped laminating device body by the bolts respectively; and the rollers make rotary motion relative to the laminating device body. According to the laminating device with the structure, the automobile door is fixed by the arranged fixing clips, and the protective film is laminated by the rollers, so that a flange of the protective film is laminated and stressed uniformly, and the frequency of no binding of the protective film is reduced or even precluded; and positions of the fixing clips can be adjusted according to different automobile types, so that the laminating device can be suitable for multiple automobile types.

The invention discloses an auxiliary device for installing a LNG ship insulating box and a using method of the auxiliary device. A plurality of rows of parallel T-shaped clamping grooves are formed inthe side wall of an insulating box panel. The auxiliary device comprises a detachable hand guided pull rod, embedded type movable clamping tongues and a lock nut, wherein at least two through holes are formed in the detachable hand guided pull rod, and the distance of the through holes is equal to the distance between any two rows of the clamping grooves; and the embedded type movable clamping tongues comprise bottoms of a T-shaped cross section matched with the clamping grooves and protruding studs connected to the bottom and extending out of the clamping grooves, the embedded type movable clamping tongues are slidably arranged in the clamping grooves, and the protruding studs penetrate through the through holes and protrude out of the through holes. The auxiliary device for installing the LNG ship insulating box has the beneficial effects that the installation efficiency of the insulating box can be improved, and the production cost, the field labor intensity and potential safety hazards are effectively reduced.
