Abstract:

The control handles on hydraulic support were most being bared without locking device, any unexpected misoperation on control handles may cause seriously accident. This paper base on the existing hidden dangers in daily production operation, through lots of analysis, designs and calculations, worked out a locking protection device for hydraulic support control handles. This locking device has many advantages such as simply structure, less components, simple manufacturing process, and better practicability. The wide application of the device will effectively avoid the economic loss and casualties cause by misoperation in using hydraulic support.

Key words: hydraulic support, control handle, locking device, design, application
