Movable Carriage Pipe Rack for Hydraulic Pump Hoist
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stationary pipe racks in hydraulic pump hoists create a dangerous and inefficient working environment due to the height and obstructions, requiring handlers to load and unload pipes from a high position, leading to safety and efficiency issues.
Innovation Solution
A support structure with moveable carriages that can rotate from a vertical to a horizontal position, allowing the load to be lowered to a safe and unobstructed position, facilitated by a four-bar linkage system and powered by hydraulic, manual, or compressed air systems, enabling stable and efficient handling of loads like pipes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If stationary pipe racks are mounted high on the pump hoist frame, then the pipe storage capacity is improved, but the working safety and operational efficiency deteriorate due to height and obstructions
Solution Approach 1:
The patent applies the dynamics principle by transforming the stationary pipe rack into a movable carriage system that can rotate between a horizontal storage position and a vertical loading position. This dynamic reconfiguration allows the pipe storage structure to adapt its position, enabling workers to load and unload pipes at ground level while maintaining high storage capacity when in the horizontal position.
Solution Approach 2:
The patent implements dimensionality change by rotating the carriage from a horizontal orientation (parallel to ground) to a vertical orientation (perpendicular to ground). This rotational movement across different spatial dimensions allows the same structure to serve dual purposes: horizontal storage and vertical loading, eliminating the need for high-mounted stationary racks.
2Quantity of substance
If stationary pipe racks are mounted high on the pump hoist frame, then the pipe storage capacity is improved, but the working efficiency deteriorates due to obstructions from the pump hoist and service body
Solution Approach 1:
The movable carriage system dynamically repositions pipes from a horizontal storage configuration to a vertical loading configuration, allowing workers to access and handle pipes at ground level without navigating around obstructions. This dynamic repositioning maintains storage capacity while eliminating the efficiency losses associated with high-mounted stationary racks.
Solution Approach 2:
The carriage acts as an intermediary mechanism between the pipe storage function and the pipe loading function. It receives pipes in horizontal storage position and transfers them to vertical loading position, mediating the transition between storage and handling operations without requiring workers to work at height or navigate obstructions.
3Ease of operation
If a movable carriage system is introduced to lower the working load, then the working safety and efficiency are improved, but the device complexity increases due to the four bar linkage system and power source requirements
Solution Approach 1:
The four-bar linkage system employs asymmetric linkages with different length arms to achieve the rotational movement of the carriage. This asymmetric mechanical design provides mechanical advantage, enabling the heavy carriage to be rotated between horizontal and vertical positions with reduced effort compared to a symmetric or direct-lift system.
Solution Approach 2:
The patent utilizes hydraulic or pneumatic power sources to actuate the movable carriage system. These fluid power systems provide controlled, high-force actuation to overcome the weight and inertia of the carriage and pipes, simplifying the operation compared to purely mechanical systems while managing the complexity through standardized hydraulic/pneumatic components.
