Hydraulic high-precision automatic leveling device with self-locking function

Abstract

The invention provides a hydraulic high-precision automatic leveling device with a self-locking function and belongs to the technical field of leveling of mechanical equipment. The hydraulic high-precision automatic leveling device comprises leveling assemblies, auxiliary rod assemblies, hydraulic power assemblies and locking assemblies, wherein four groups of leveling assemblies are connected with each other through the auxiliary rod assemblies to form a quadrangle as same as a mechanical equipment base; main power for lifting of each group of leveling assemblies is provided by the same hydraulic power assembly; the hydraulic power assembly is communicated with oil cylinder main bodies in the leveling assemblies through an oil inlet valve and an oil returning valve which are integrated, so that any group of oil cylinder rods can be independently driven to lift; a flat spring is further arranged each leveling assembly; the flat springs can buffer return oil of the oil cylinder main bodies and protect the mechanical equipment needed to be leveled and the leveling assemblies; through the locking assemblies arranged on lifting limiting bases, the hydraulic power can be eliminated and converted into mechanical locking after locking lifting shafts at any height positions; and the hydraulic high-precision automatic leveling device is energy-saving, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment leveling, in particular to a hydraulic high-precision automatic leveling device with a self-locking function. Background technique [0002] The leveling and alignment work of equipment installation is carried out after the equipment is hoisted in place and before the equipment is operated. The task is to install the equipment to meet the quality standards required by the technology through adjustment. The precise leveling of equipment has an important impact on the work quality and efficiency of subsequent equipment. [0003] The traditional method of leveling mechanical equipment is to place shim iron at the required height on one end of the machine base, and also place shim iron at the required height on both sides of the anchor bolts at the other end, and then use a level to adjust the level on the processing surface of the machine base. Look up the level, screw on the anchor bolt...

Problems solved by technology

[0003]The traditional method of leveling mechanical equipment is to place shims at one end of the machine base at the required height, and also place them on both sides of the anchor bolts at the other end. Use a spirit level to find the level on the processing surface of the machine base, and then screw on the anchor bolts after leveling, and finally add a shim to the anchor bolts, find the level, and screw on the anchor bolts after leveling. Or use other hand-twist-type foundation leveling devices to replace the foundation bolts for leveling, such as a kind of mechanical equipment leveling device disclosed in the prior art (CN 210771049 U), comprising a load-bearing plate, the rear side of the upper surface of the load-bearing plate The middle position is fixed with a threaded column, the outer surface of the threaded column is sleeved with a screw barrel, the upper end surface of the threaded column is against the lower surface of the receiving body, the upper part of the receiving body is fixedly provided with a connecting hole, and the receiving body is rotatably connected to the lower part of the connecting block. The block is fixedly connected to the lower surface of the bearing plate, and the size of the bearing plate is the same as that of the load-bearing plate. The two sides between the receiving plate and the load-bearing plate are fixedly connected with brackets, and the middle of the bracket is connected with a turntable. , the rear part is provided with a support structure, although the multi-directional tilt adjustment of the leveling plate can be realized, but because the angle of tilt adjustment is too large in the actual use process, the mechanical equipment will roll over, and this kind of hand-tightening bolt is used The way of leveling is that the damage to the bolts is great. Once the weight of the mechanical equipment exceeds the bearing capacity of the bolts, the leveling will fail; the second is that the leveling accuracy is low, which cannot meet the current increasingly sophisticated mechanical equipment.
