Abstract
The utility model provides a hydraulic support detaching backing plate including a second backing plate for dragging a hydraulic support to be detached thereon, a first backing plate erected on a slideway and dragging the hydraulic support to be detached on the second backing plate to the first backing plate itself, and a connecting device, and the second backing plate is hinged to the right side of the first backing plate via the connecting device. When the hydraulic support is detached, the hydraulic support detaching backing plate is paved between the support to be detached and the slideway, so that the bottom of the support to be detached don't have to be directly contacted with the bottom plate of a soft and uneven fully mechanized working panel. Because the support to be detached cannot encounter barriers caused by the unevenness of the bottom plate, the bottom of the support to be detached cannot abut against the uneven part of the bottom plate, and the dragging resistance is low; moreover, when the support to be detached is dragged on the hydraulic support detaching backing plate, the friction coefficient between the support to be detached and the hydraulic support detaching backing plate is low, and the dragging friction force is less.
