Guide Rail Vehicle Wheel Height Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide wheel support apparatuses for guide rail type vehicles face challenges in uniformly adjusting the height of guide wheels, require complex manual operation, and are prone to issues like rust and misalignment, which can lead to reduced durability and ineffective link function.
Innovation Solution
A guide rail type vehicle with a support receiver and adjustment device that allows for easy and reliable height adjustment of guide wheels and switching wheels without altering the guide bar height, using height adjustment shims and a mechanism with teeth and bolts to simplify the process and prevent unnecessary force on the link.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the guide wheel support apparatus with a bushing and wheel axle is used for height adjustment, then the guide wheel height can be adjusted, but it becomes difficult to adjust both the guide wheel and switching wheel heights uniformly
Solution Approach 1:
The invention merges the adjustment mechanisms for the guide wheel and switching wheel into a single integrated support apparatus. The support apparatus includes a support body with a first support surface for the guide wheel and a second support surface for the switching wheel, allowing both wheels to be adjusted simultaneously by adding or removing shims at one location, thereby achieving uniform height adjustment while simplifying the operation process.
2Duration of action of stationary object
If the guide wheel support apparatus is used over an extended period, then rust and interference occur at the axle portion, but disassembly and repair are required
Solution Approach 1:
The invention extracts the wheel axle from the bushing structure and replaces it with a solid support body that directly supports both the guide wheel and switching wheel. This eliminates the slit in the support body and prevents rust and interference at the axle portion, extending service life while eliminating the need for disassembly and repair.
3Manufacturing precision
If the guide bar height is adjusted to change guide wheel height, then the guide wheel height can be changed, but the guide bar may become non-horizontal causing excessive force on the link
Solution Approach 1:
The invention segments the height adjustment function from the guide bar structure. The guide bar maintains its fixed horizontal position, while the support apparatus mounted on the guide bar provides the height adjustment capability through shims. This separation ensures the guide bar remains horizontal and prevents excessive force on the link, maintaining reliability while achieving the desired guide wheel height.

AI summary
A guide rail type vehicle is provided with a guide wheel that comes into rolling contact with a guide rail, a switching wheel that is comes into rolling contact with a switching rail installed at a switching location of the guide rail, a wheel axle in which the guide wheel is connected to the top end and the switching wheel is connected to the bottom end, a support receiver of which the height dimension is set to be smaller than the corresponding length dimension of the wheel axle and which supports the wheel axle, and adjustment device which adjusts the sizes of a gap of the guide wheel side and a gap of the switching wheel side, which are accessed from a direction orthogonal to the axial direction of the wheel axle, and are therefore capable of adjusting the height of the guide wheel and the switching wheel.
