Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing jig devices for attaching concrete forms and bolt cages to drilling rigs lack the flexibility and precision needed for efficient maneuvering, particularly in adjusting to varying sizes and positions of bolt cages and concrete forms.
Innovation Solution
A jig device comprising a hub unit with telescopically adjustable spokes that attach to a kelly bar of a drilling rig, equipped with bolt jigs for securing bolt cages and yoke supports for adjustable attachment to concrete forms, allowing for precise and flexible positioning of both the concrete form and bolt cage with the drilling rig.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional jig devices are used for attaching concrete forms and bolt cages, then the equipment is simpler in structure, but the positioning accuracy and maneuverability are insufficient
Solution Approach 1:
The jig device is segmented into multiple independent components: a hub unit with multiple spokes, each spoke can independently adjust its length, and each spoke can independently engage with bolt cages or concrete forms. This segmentation allows precise positioning of each component while maintaining overall structural coherence, resolving the contradiction between positioning accuracy and structural simplicity.
Solution Approach 2:
The device incorporates dynamic adjustment capabilities through telescopic spokes with adjustable lengths and slidable connections. The spokes can be extended or retracted to different positions, and the yoke supports can slide along the spokes to accommodate varying distances from the hub unit. This dynamic adaptability enables precise positioning for different drilling configurations without requiring multiple fixed-structure devices.
2Adaptability or versatility
If fixed-length spokes are used, then the device structure is simpler, but the adaptability to different drilling configurations is reduced
Solution Approach 1:
The spokes are designed as telescopic structures with adjustable lengths, allowing each spoke to be dynamically configured for different drilling depths and angles. The slidable yoke supports further enhance adaptability by allowing adjustment of the distance from the hub unit. This dynamic design enables a single device to adapt to various drilling configurations without requiring multiple specialized tools.
Solution Approach 2:
The hub unit with multiple adjustable spokes serves multiple functions: it can engage with bolt cages through bolt jigs, attach to concrete forms via yoke supports, and accommodate different drilling rig configurations. Each spoke can independently perform different functions, making the overall device universally applicable to various drilling scenarios, thereby improving adaptability without proportionally increasing complexity.
3Productivity
If manual positioning methods are used, then the equipment is simpler, but the operational efficiency and speed of positioning are reduced
Solution Approach 1:
The device transitions from manual two-dimensional ground positioning to three-dimensional spatial positioning utilizing the drilling rig's vertical movement capability. The hub unit attaches to the vertically moving kelly bar, and the adjustable spokes extend radially outward to engage bolt cages and concrete forms at different heights and angles. This three-dimensional manipulation enables faster and more precise positioning compared to traditional manual methods, improving operational efficiency despite increased mechanism complexity.

AI summary
A drilling jig assembly includes a hub unit that has a receiver and a plurality of spokes and the receiver engages a kelly bar of a drilling rig. A plurality of bolt jigs is each coupled to a respective one of the spokes on the hub unit to receiving a respective one of a plurality of bolts of a bolt cage. A plurality of yoke supports is each slidably disposed on a respective one of the spokes of the hub unit such that each of the yoke supports is spaceable an adjustable distance from the receiver of the hub unit. Each of the yoke supports can be attached to a concrete form surrounding the bolt cage thereby facilitating the concrete form to be maneuvered by the drilling rig when the receiver of the hub unit is attached to the drilling rig.
