The described braced structures that is used to change coal plough planer head piston shoes has pin-and-hole and hole on the bracing frame, bearing pin pack into bracing frame pin-and-hole and with guide rail in the corresponding pin-and-hole, bearing pin one end adopts bolt I and bracing frame to fix; The bolt II pack into bracing frame the hole and with guide rail in the corresponding hole, bracing frame is fixed by bolt II and guide rail.
Advantage of the present utility model and beneficial effect are:
1, braced structures of the present utility model is mainly by bracing frame, pin and bolt are formed, after the planer head piston shoes wear extent value of reaching capacity, guide strip is removed, bracing frame is installed on the carriage rail, and bracing frame and guide rail are fixed together with pin and bolt, after removing the wear-resistant sleeve of planer head, slowly move bracing frame on along the bracing frame inclined-plane planer head one side, make piston shoes lift certain altitude, just piston shoes can be disassembled, be replaced by new piston shoes, after replacing finishes, planer head slowly is withdrawn on the guide rail along the bracing frame inclined-plane, bracing frame is installed on the planer head opposite side guide rail, press with the replaceable opposite side piston shoes of quadrat method.
2, after the utility model bracing frame is installed on the guide rail, use pin and bolt that itself and guide rail are fixed, both can prevent to draw in the planer head process play forward, can prevent that again bracing frame from tilting to both sides.
3, the utility model bracing frame is a bilateral symmetry, and same bracing frame is installed in both sides, planer head front and back respectively, two piston shoes all can be obtained changing.
4, the utility model is simple in structure, and is easy for installation, planer head need not be disassembled just more to renew piston shoes, and installation rate is fast, reduces labour intensity, strong assurance production efficiency.
