Loading Cart Conveyor Belt Alignment via Automatic Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing loading wagons face challenges in achieving a seamless coupling with another wagon for continuous transport, particularly in ensuring the discharge end of the transfer conveyor belt aligns correctly with the support device for efficient bulk material transfer.
Innovation Solution
A third blocking device is introduced that automatically fixes the transfer conveyor belt, preventing movement about the vertical pivot axis, ensuring the discharge end aligns correctly with the support device during coupling, facilitating faster and problem-free transfer initiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the transfer conveyor belt is allowed to pivot freely about the vertical axis, then the loading wagon can be coupled quickly, but the discharge end cannot be precisely aligned with the support device
Solution Approach 1:
The blocking device is pre-positioned in the blocking position before coupling occurs. When the transfer conveyor belt is lowered, the blocking element automatically engages with the strip of elastic material, pre-establishing the correct alignment position. This preliminary positioning ensures that when coupling happens, the discharge end is already precisely aligned with the support device, eliminating the need for post-coupling adjustment.
2Manufacturing precision
If a blocking device is used to fix the transfer conveyor belt position, then alignment precision is improved, but the device complexity increases
Solution Approach 1:
The blocking device operates autonomously without requiring external control systems, operators, or additional power sources. The blocking element connected to the transfer conveyor belt automatically engages with the strip of elastic material mounted on the chassis frame when the belt is lowered, using the belt's own movement to trigger the blocking action. This self-service mechanism achieves precise alignment while minimizing added complexity.
Solution Approach 2:
A strip of elastic material serves as an intermediary between the blocking element and the chassis frame. This elastic strip provides a simple yet effective blocking surface that can be engaged or disengaged by the blocking element's vertical movement, creating a straightforward mechanical interface that achieves precise positioning without complex mechanisms.
3Manufacturing precision
If the transfer conveyor belt is lowered for coupling, then alignment is achieved, but the blocking device must be automatically actuated
Solution Approach 1:
The blocking function is merged with the existing lowering movement of the transfer conveyor belt. The blocking element is connected to the belt such that the same vertical movement used to position the discharge end also actuates the blocking mechanism. This combining of functions eliminates the need for separate actuation systems, achieving automatic blocking through the belt's own positioning movement.

AI summary
The invention relates to a loading cart for transporting and storing bulk material, having a locking device (22) formed by a locking element (24) connected on one side to a transfer conveyor belt (10) and on the other side to a frame segment (23) below the belt. Both locking elements (24) are spaced apart from one another with respect to a vertical direction in a non-locking position during operation of the transfer conveyor belt (10). A locking position can be achieved automatically by lowering the transfer conveyor belt (10) and thus the locking element (24) connected thereto onto the locking element (24) located below belt.
