The invention relates to the technical field of vacuum adsorption conveying devices, in particular to a large-size planar rock sample hoisting device. The hoisting device comprises a vacuum sucker, a vacuum pump and a hoisting frame. The vacuum sucker is mounted at the lower end of the hoisting frame. The vacuum sucker comprises a plurality of adsorption regions from inside to outside. All the adsorption regions are connected with the vacuum pump through air pipes. The air pipe of each adsorption region is provided with an air valve so that all the adsorption regions can be independently controlled. Meanwhile, a vacuum relief valve, a vacuum pressure meter and a pressure warning unit are arranged and used for monitoring the vacuum degrees of the adsorption regions in the working process and giving an alarm when the vacuum degrees are not enough. The large-size planar rock sample hoisting device can conduct vacuum adsorption conveying and mounting on large-size planar rock samples; the rock samples can be directly hoisted onto an instrument; operation is easy, and the surfaces of the rock samples cannot be damaged; the hoisting capacity is high, and the large-size planar rock sample hoisting device is stable and reliable in the hoisting process and high in safety coefficient.
