The utility model provides a kind of pre-expander with water vapor removal function, including the pre-expander body for foaming treatment to foam particle;Pre-expander further include exhaust hood, induced draft fan, exhaust pipe, corrugated expansion pipe and height adjusting mechanism;Exhaust hood is located above the water vapor discharge port of pre-expander body, height adjusting mechanism is connected on the outer side wall of pre-expander body, exhaust hood is fixed on the adjusting end of height adjusting mechanism, and height adjusting mechanism is used to adjust the interval between exhaust hood and water vapor discharge port;Exhaust pipe is hoisted and fixed on ceiling, one end of corrugated expansion pipe is connected with air outlet located at the top of exhaust hood, the other end of corrugated expansion pipe is connected with one end of exhaust pipe, the other end of exhaust pipe is extended to outdoor and connected with induced draft fan;The utility model can make that excess water vapor is quickly discharged from pre-expander body, to ensure the rapid drying of foam particle after subsequent foaming is completed.

The utility model discloses a kind of lifting appliance for T beam reinforcement cage, belong to T beam reinforcement cage hoisting equipment technical field, specific structure includes truss, chain and chain shackle, truss top side symmetrical fixedly connected with fixed seat, fixed seat top side center is provided with the hanging hole for hanging connection travelling crane hook, two chain shackle are set in the both ends of each chain, chain adopts multiple groups, along the truss length direction evenly arranged, each group of chain adopts four, and each chain middle part is fixedly connected on truss, and each chain shackle is hung on the reinforcement of T beam reinforcement cage.This utility model adopts multiple groups of chain and chain shackle to evenly hang the reinforcement on the top plate of T beam reinforcement cage, cooperate with the truss of strip frame structure, hoist stable and reliable, stress is uniform, ensure that T beam reinforcement cage is hoisted smoothly, not deformed, avoid damaging T beam reinforcement cage;Complete reinforcement cage is welded outside mould, and space is big, more conducive to welding production.

The application provides a synchronous hoisting mechanism of a special machine for repairing a sealing weld, which comprises a plurality of clamping modules for being fixed on a scaffold platform, a hoisting frame and a synchronous hoisting module installed on the hoisting frame, the scaffold platform is arranged above a control rod drive mechanism to be repaired, the clamping module comprises a supporting leg fixing seat, the hoisting frame comprises a plurality of supporting legs and a supporting beam, the number of the supporting legs is the same as that of the supporting leg fixing seats, the lower ends of all the supporting legs are connected to all the supporting leg fixing seats one by one, the upper ends of the supporting legs are connected to the end portions of the supporting beam, the synchronous hoisting module comprises a fixing disc installed on the supporting beam, a plurality of groups of fixed pulley sets installed on the fixing disc and a plurality of groups of movable pulley sets connected to all the fixed pulley sets through pull ropes, and a lifting hook for being connected to a lifting opening of the special machine for repairing a sealing weld is installed on each group of the movable pulley sets. The synchronous hoisting mechanism can realize stable hoisting of the special machine.

The utility model discloses a point type contact modularized missile and rocket hoisting structure which comprises a hoisting seat fixed at a hoisting point of a shell of a missile and rocket product and a plug used for packaging the hoisting seat, the connecting cylinder at the upper end of the hoisting seat is inserted from the lower end of the connecting unthreaded hole at the hoisting point of the shell of the projectile product, the connecting plate at the bottom of the hoisting seat is fixed on the inner wall of the shell of the projectile product through a screw, and the plug is fixed in an inner cavity of the connecting cylinder of the hoisting seat. During hoisting operation, the plug is detached from the connecting cylinder at the upper end of the hoisting seat, the lower end of each sling is connected with a threaded connecting column, and each sling is in threaded connection with the connecting cylinder at the upper end of the hoisting seat through the threaded connecting column, so that point type contact projectile hoisting can be realized. According to the modularized projectile hoisting structure, reliable hoisting of projectiles is achieved, and safety and product quality can be improved. After hoisting is finished, a plug is screwed into a threaded hole of a connecting cylinder at the upper end of the hoisting seat, and the pneumatic requirement and the heat insulation requirement of the projectile are met.
