Laterally Movable Platform for Railway Drilling Tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing drilling/ramming devices on railway wagons have a limited range of movement due to the width of the loading area, which restricts their action across the longitudinal stretching of the wagon, making it difficult to insert foundation recesses effectively next to a track.
Innovation Solution
A movable platform with retractable widening elements is mounted on the loading area of the railway wagon, allowing the platform to extend laterally and support the drilling/ramming device on the ground, thereby increasing the range of movement and accommodating the device's weight distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the loading platform width is increased to expand the drilling/piling rig's operating range, then the range of movement transverse to the longitudinal extent is improved, but the loading gauge geometry constraints prevent this widening
Solution Approach 1:
The patent applies the dynamics principle by making the platform width adjustable through retractable extension elements. The platform can dynamically change its width: narrow when retracted to comply with loading gauge constraints during transport, and wide when extended to provide sufficient operating range for the drilling/piling rig during work operations. This dynamic adaptation resolves the contradiction between fixed width limitations and the need for variable width functionality.
Solution Approach 2:
The patent resolves the width limitation by transitioning from a two-dimensional platform width constraint to a three-dimensional solution with retractable extension elements that project laterally beyond the main platform edges. This adds a dimensional aspect of extendability, allowing the platform to effectively increase its working area without permanently exceeding the loading gauge envelope during transport.
2Area of moving object
If the platform is moved laterally to increase working area to the side of the track, then the range of movement is improved, but the drilling/piling rig weight must be supported by extension elements over a relatively short distance
Solution Approach 1:
The extension elements are designed with multi-functionality to address the weight support challenge. Each extension element incorporates both the lateral extension function and integrated support elements that can bear the drilling/piling rig weight. This universal design allows the same structural component to perform both the function of extending the platform width and the function of supporting heavy loads, eliminating the need for separate support structures and making effective use of the limited projection distance.

AI summary
A device (14) for laterally displacing a drilling/piling device (16) positioned on a railway wagon (10) with a loading platform (12) for creating foundation recesses in the subsoil (92) next to a track is provided with a laterally movable platform (32) on which the drilling/piling device (16) can be positioned, the platform (32) having two lateral edges (30, 34) facing away from each other. The platform (32) is supported by a support unit (40) with at least one automatically extendable and retractable extension element (36), which, in an extended position, projects laterally beyond one of the lateral edges (30, 34) of the platform (32) and, in a retracted position, is set back from the extended position.The at least one extension element (36) has at least one extendable support element (38) that can be moved from a rest position into a support position for supporting the at least one extension element (36) on a base (92). In the extended position of the at least one extension element (36), the platform (32) can be moved laterally along it automatically.
