Crane Silo Dosing Device Actuation via Hydraulic Piston
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The handling of building materials via a conveyor hose from a crane silo is cumbersome and poses safety risks due to the need for manual operation and the instability of the dosing device, which affects the balance and accessibility, leading to inefficient and unsafe working conditions.
Innovation Solution
A hydraulic piston-cylinder unit is used to actuate the dosing device on the conveyor hose, utilizing a gas accumulator to generate counterpressure for opening and closing the conveying cross-section, allowing for controlled and reliable operation with a controllable hydraulic pump system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual operation of the dosing device is used, then device complexity is reduced, but ease of operation deteriorates and safety risks increase
Solution Approach 1:
The patent replaces manual mechanical operation with an automated piston-cylinder unit that uses hydraulic or pneumatic pressure to open and close the dosing device. This substitution eliminates the need for manual handling while maintaining device functionality, directly resolving the contradiction between simplicity and ease of operation.
2Adaptability or versatility
If the dosing device is made adjustable on the conveying area, then adaptability improves, but stability of the system deteriorates due to balance changes
Solution Approach 1:
The patent introduces a counterweight mechanism that compensates for the changing weight distribution when the dosing device is adjusted. The counterweight system automatically balances the crane silo as the dosing device moves to different positions, maintaining stability while preserving full adjustability for different conveying requirements.
3Reliability
If a hydraulic piston-cylinder unit with gas accumulator is used, then reliability improves, but device complexity increases
Solution Approach 1:
The patent employs a hydraulic or pneumatic piston-cylinder unit with a gas accumulator to actuate the dosing device. This system provides reliable, controlled movement through fluid pressure while using the gas accumulator to store energy and maintain consistent operation. The complexity is justified by the significant improvement in reliability and controlled operation of the dosing device.

Implementation Method 1
by means of a piston-cylinder unit that can be acted upon by a hydraulic pump by means of a hydraulic force compressing a gas with the opening movement for a prestressed closing movement of the dosing device into a counterforce to the opening movement
Implementation Method 2
a controllable hydraulics pump line-connected to a piston-cylinder unit separating a piston into two cylinder chambers with the first cylinder space for receiving a liquid medium and the cylinder space behind the piston to generate a closing pressure on a gas storage facility connected as a counterpressure means

AI summary
The method involves forming filling opening in the upper end and forming discharge opening (3) for removal of building material in lower end of crane silo (1). The discharge opening of container (2) is operatively connected to conveying hose (5), to face the conveyor region for closing and opening the adjustable metering device (8). The opening of metering device forms a conveying cross section of delivery hose with opening movement. The gas for pre-stressed closing movement of metering device in counterforce with closing pressure is compressed for the opening movement. An independent claim is included for crane silo.
