Mobile Crusher Boom System With Movable Column
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rock breaker/manoeuvring boom systems for mobile crushers have limited range of motion and are prone to damage from debris, leading to increased downtime and maintenance costs due to the hydraulic ram's exposure and proximity to the crusher's side wall.
Innovation Solution
A mobile boom system with a moveable upright column that adjusts its position relative to the base, allowing the boom arm to actuate through a greater angle and reducing exposure to debris, enhancing mechanical advantage and range of motion while maintaining a compact transport configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the hydraulic ram is located on the underside of the mobile boom system to provide mechanical advantage, then the range of motion is improved, but the hydraulic ram is exposed to debris from the grizzly which can damage it
Solution Approach 1:
The patent relocates the hydraulic ram from the traditional underside position to the outer side of the boom arm, changing the spatial dimension of the actuator's location. This dimensional shift allows the ram to maintain mechanical advantage while being positioned away from the debris-prone area near the grizzly, thus resolving the contradiction between range of motion and component protection.
2Area of stationary object
If the mobile boom system is mounted close to the external side portion of the crusher to minimize dimensions, then the crusher roadworthiness is maintained, but the boom arm has limited range of motion before contacting the side wall
Solution Approach 1:
The patent introduces a movable platform that can shift position along the boom arm's path of travel. This dynamic adjustment allows the boom arm to achieve greater effective range of motion by repositioning its pivot point, while the entire assembly remains compact when mounted close to the crusher side wall, resolving the contradiction between compact dimensions and operational range.
3Length of stationary object
If the column height is minimized to keep the crusher within transport dimensions, then the roadworthiness is maintained, but the mechanical advantage and range of motion are reduced
Solution Approach 1:
The patent positions the hydraulic ram to act on the boom arm at an optimized point that maximizes mechanical advantage within the constrained column height. By carefully selecting the actuation point and angle before operation begins, the system achieves sufficient force multiplication despite the minimized column height, resolving the contradiction between compact dimensions and mechanical advantage.
