- The torque of the column-type Pneumatic Industrial Manipulator is concentrated at the base. The foundation has to bear not only the vertical weight, but alsoOverturning moment caused by rotation and eccentric load。
- Foundation confirmation should coverGround bearing, concrete condition, anchoring method, embedded foundation, levelness and working radiusSix aspects.
- It is not appropriate to apply fixed values to the specific foundation thickness and anchor bolt specifications. They should be based onEquipment loads, operating radius and final installation drawingsshall prevail.
- Do not install directly on an inadequate foundation; evaluate an embedded or reinforced foundation, or use an overhead-mounted or rail-mounted configuration.
Pneumatic Industrial Manipulators are not devices that can be simply placed on site and used. In particular, column structures usually need to be reliably connected to the ground through the base. During the lifting, rotation, telescopic, and pick-and-place processes of the equipment, the rated load, the self-weight of the fixture, and the force generated by the operating actions will be transmitted to the installation foundation.
01Why does the foundation affect the use of Pneumatic Industrial Manipulator?
If the bearing capacity of the foundation is insufficient, problems such as loosening of the base, shaking of the column, unstable rotation, and increased positioning deviation may occur. The characteristic of the column structure is that the moment is concentrated in the base area: when the working radius increases, the workpiece is obviously unbalanced, or the fixture structure is long, the foundation bears not only the vertical weight, but also the rotation and unbalanced loads.Overturning moment. Therefore, foundation requirements cannot just be based on whether the ground "looks solid", but should be confirmed in conjunction with equipment load, scope of work, and final installation drawings.
02Main contents of foundation confirmation
Ground bearing capacity
The load bearing includes not only the weight of the equipment body, but also the weight of the workpiece, the weight of custom tooling, load changes during dynamic operation, and repeated forces during long-term use. Equipment requirements for different models, loads, and operating radius are different. The specific load-bearing conditions need to be confirmed based on the equipment load, operating radius, and final installation drawings.
concrete floor condition
Column-type Pneumatic Industrial Manipulators usually need to be installed on reliable concrete floors or confirmed infrastructure. The ground should be checked for hollowing, cracking, sanding, interlayering, looseness, obvious settlement, etc. If the floor is only a surface leveling layer, or if there are pipe trenches, drainage channels, floor heating, embedded pipelines, or cavity structures underneath, it may not be suitable for direct installation. This should be explained in advance and reviewed by a professional.
Expansion bolts or chemical anchor bolts fixing conditions
Common fixing methods include expansion bolts, chemical anchors or other engineering anchoring methods. It is necessary to pay attention to whether the ground is allowed to be drilled, whether the hole position avoids steel bars and pipelines, whether the depth of the foundation meets the anchoring requirements, and whether the installation surface is integrated. If the concrete strength in the anchorage area is insufficient or there is a loose layer, it may result in insufficient bolt pullout force and affect long-term stability.
Is it necessary to bury the foundation in advance?
For working conditions with larger loads, larger operating radius, frequent use or higher requirements for positioning stability, it may be necessary to set up embedded foundations. The embedded foundation should be constructed in advance according to the installation drawings before the equipment is installed. Its size, structure, steel bar configuration, embedded parts form and construction requirements must be confirmed according to the final installation drawings and should not be temporarily processed on site.
Levelness of mounting surface
The level of the foundation will affect the verticality of the column, the smoothness of rotation and the operating feel. If the installation surface is uneven, uneven rotation resistance, natural deflection of the arm, unstable positioning, or excessive local stress may occur. Before installation, the levelness of the installation area should be checked, and if necessary, leveling, pad adjustment or foundation trimming should be carried out.
Equipment rotation radius and load changes
Foundation confirmation cannot just look at the location of the base. When the column-type Pneumatic Industrial Manipulator has different angles, different extension lengths, and different workpiece conditions, the force on the foundation will change. When the workpiece stays at the maximum working radius, when the fixture is picked and placed eccentrically, or when it needs to be flipped or rotated, the torque on the base area will increase. During on-site confirmation, the actual transportation path, maximum extension position, operator position and peripheral equipment layout should be included in the scope of review.
03Suggestions for dealing with insufficient foundation
If the site foundation is inadequate, do not install the equipment directly. Options include an embedded foundation, a reinforced foundation, relocation, or a configuration better suited to the site, such as a standalone foundation, reinforced steelwork, a widened base, a jib-crane structure, an overhead-mounted manipulator, or a rail-mounted handling system. Select the final solution based on site conditions, rated load, operating radius, building structure, and approved installation drawings.
