This utility model relates to the field of rebar cage hoisting technology, specifically a rebar cage integral hoisting device, including a mounting plate. Several slide rails are fixedly connected at equal intervals on the lower surface of the mounting plate. A slider is slidably connected to each slide rail. A fixing plate is fixedly connected to the lower surface of each slider. A hook is provided at the lower end of the fixing plate. A drive motor is installed at the center of the upper end of the mounting plate. The output end of the drive motor passes through the mounting plate and is provided with a disc. Several push-pull rods are rotatably connected at equal intervals on the disc. The other end of each push-pull rod is rotatably connected to the fixing plate. This utility model solves the problems of rebar cage falling from heights during existing hoisting processes, and the inability to guarantee the verticality of the rebar cage after hoisting, making it difficult for a tilted rebar cage to enter the pile hole.

The embodiment of the application provides a kind of multi-station press balancer air pressure's adjusting method, system, equipment and medium, belong to multi-station press field.It includes: the mass parameter of the mould on each station of multi-station press, center of gravity offset, the structural parameter of balancer, the distance from balancer to slider center, no-load air pressure and safety air pressure parameter;According to the above parameters, the required off-load compensation force of balancer is calculated, and the target air pressure value required by balancer is calculated in combination with no-load air pressure;And based on target air pressure value and safety air pressure parameter, determine the upper and lower limit of air pressure;The actual air pressure value of left and right balancer is collected in real time by pressure sensor;And compare actual air pressure value with air pressure upper and lower limit, based on operating state and comparison result control air intake or exhaust.Can realize the automatic compensation of multi-station press off-load, avoid the eccentric force of slider caused by the weight difference of mould, improve the running safety, stability and die changing efficiency of press.
