Rotating Control Box Connection for Compact Fracturing Unit Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In fracturing apparatuses, the close proximity of the transmission component and control box complicates maintenance operations due to space constraints, making it difficult to access and maintain the transmission component effectively.
Innovation Solution
A connection device that allows the control box to be moved from a first position to a second position relative to the fixation rack, creating an operation space for the transmission component by using a fixation rack and a box connection mechanism, which includes a rotation shaft and limitation components to securely lock the control box at different positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the control box is positioned close to the transmission component, then the device occupies less space and has a more compact structure, but the maintenance operation of the transmission component becomes difficult
Solution Approach 1:
The control box is designed with movable positioning capability, allowing it to be relocated between a first position (close to transmission component during operation) and a second position (away from transmission component during maintenance). The box connection mechanism enables this dynamic repositioning, resolving the contradiction between compact structure and maintenance accessibility.
Solution Approach 2:
The control box is positioned in a direction perpendicular to the axis of the transmission shaft, utilizing spatial arrangement in multiple dimensions. This perpendicular positioning allows the control box to be close to the transmission component without obstructing maintenance access when properly oriented.
2Ease of repair
If the control box is moved away from the transmission component to form an operation space, then the maintenance operation becomes easier, but the device occupies more space
Solution Approach 1:
The control box transitions from a static position to a dynamic, relocatable position. During maintenance, it moves to a second position that creates operation space, while during normal operation, it returns to a first position for compact arrangement. This dynamic behavior resolves the space-maintenance contradiction.
3Device complexity
If the control box is fixed in position, then the structure is simpler and more stable, but the maintenance operation of the transmission component is complicated
Solution Approach 1:
The control box is designed with movable positioning capability, allowing it to be relocated between a first position (close to transmission component during operation) and a second position (away from transmission component during maintenance). The box connection mechanism enables this dynamic repositioning, resolving the contradiction between compact structure and maintenance accessibility.

AI summary
A fracturing device includes a power unit, and the power unit includes a muffling compartment, a turbine engine, and an air intake unit. The air intake unit is communicated with the turbine engine through an intake pipe and configured to provide a combustion-supporting gas to the turbine engine; the air intake unit is at a top of the muffling compartment and the muffling compartment has an accommodation space, the turbine engine is within the accommodation space. A fan is further provided to generate wither positive pressure or negative presser in the muffling compartment to facilitate a cooling of the turbine engine.
