AI Technical Summary
Existing cement manhole cover clamping and handling devices lack the support force for the bottom of the manhole covers when clamping multiple manhole covers at once, which makes the manhole covers easy to shake during handling, affecting stability and even causing the manhole covers to fall off.
A cement manhole cover clamping and handling mechanism was designed. A first cylinder drives the clamping seat to move up and down. A second cylinder and an adjusting plate are used to clamp the manhole cover with an arc-shaped clamping plate. The bottom of the manhole cover is supported by a support plate and fixed with fastening screws to improve stability.
The support plate at the bottom of the manhole cover enhances its clamping stability, preventing shaking and detachment, and improving the safety and efficiency of handling.
