Shoring Support Structure Powered Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional acrow props are difficult to install single-handedly and are manually installed, making them slow and labor-intensive, especially when numerous props are needed to support large areas.
Innovation Solution
The extendable structure incorporates a bevel gear and pinion gear system that allows for powered actuation using tools like drills or impact drivers, enabling easier and faster installation and removal by rotating the collar, which adjusts the inner tube's height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual installation method is used, then no additional equipment is needed, but installation speed and efficiency are low
Solution Approach 1:
The collar is designed to serve dual purposes: it can be manually rotated by hand for adjustment, or it can receive powered actuation through the bevel gear and pinion gear system. This multi-functionality allows the same component to accommodate both manual and powered installation methods, thereby improving productivity without requiring completely different equipment configurations.
Solution Approach 2:
The bevel gear and pinion gear system acts as an intermediary mechanism that translates the rotational output of common power tools (drills, impact drivers) into the rotational motion of the collar. This intermediary gear system enables powered actuation while maintaining compatibility with the existing collar design, thus improving installation speed without requiring direct coupling of power tools to the collar.
2Ease of operation
If manual rotation of collar is used, then simple operation is possible, but single-handed installation is difficult
Solution Approach 1:
The bevel gear and pinion gear system serves as a mechanical intermediary that converts the high-speed rotation of power tools into the controlled rotation of the collar. This allows a single operator to easily install the prop by simply attaching the power tool and activating it, eliminating the need for one-handed manual rotation while maintaining operational simplicity.
Solution Approach 2:
The invention replaces the manual mechanical rotation system with a powered actuation system using common power tools. Instead of requiring manual effort to rotate the collar, the system substitutes this mechanical action with powered rotation transmitted through the bevel gear and pinion gear, thereby easing the operation and enabling single-handed installation.
3Reliability
If numerous props need to be installed, then adequate support is provided, but installation time becomes excessive
Solution Approach 1:
The invention changes the key parameter of installation speed by introducing powered actuation. Each prop can be installed much faster using power tools, and since the prop design remains unchanged, the reliability and support adequacy are maintained. This parameter change in installation speed directly addresses the time loss when installing numerous props.
Solution Approach 2:
The powered actuation system enables continuous and rapid installation of multiple props without the interruptions and fatigue associated with manual installation. The consistency and speed of powered actuation allow for continuous productive action when installing numerous props to support large areas, thereby reducing total installation time while maintaining adequate support.

AI summary
A shoring support structure (3) comprising an outer tube (2) having a threaded region (22) with opposing longitudinal slots (16) and an inner tube (4) slidable within the outer tube and having a plurality of pairs of transverse holes (14) at spaced apart intervals. The inner tube and outer tubes terminate in a plate (6) and a pin (10) is receivable through the slots of the outer tube and a pair of transverse holes of the inner tube. A collar (8) is mounted on the threaded region and is rotatable to raise and lower the pin within the slots. The collar includes a driven member (30) such as a bevel gear for mating with a driving member (32) such as a pinion connectable to an actuator (38), actuation of the driving member causing rotation of the driven member to effect rotation of the collar (8) to move the pin.
