Monitoring support

The utility model relates to the technical field of mine survey, in particular to a monitoring support. Comprising a base, the upper end of the base is fixedly connected with a bearing plate, the lower end of the base is rotatably connected with three supporting sleeves, the supporting sleeves are slidably connected with supporting rods, sliding grooves are formed in the supporting sleeves, the supporting rods are fixedly connected with limiting columns, the limiting columns are matched with the sliding grooves, and the supporting rods are in threaded connection with fixing bolts. Clamping structures are arranged at the upper ends of the bearing plates, and limiting structures are arranged at the lower ends of the supporting rods. The ground grabbing plate of the device is placed in a target area, then the fixing pile is pushed into the ground, at the moment, the semicircular limiting block clamps the fixing pile, the fixing pile is not prone to moving, the device can fix the position below the ground, the fi
