Aforesaid coal-winning machine wheel shaft is prevented unloading device, and preferably, said plate comprises top board and insert plate that the lateral dimension of said top board is greater than the lateral dimension of said inserting plate hole.
Aforesaid coal-winning machine wheel shaft is prevented unloading device, and preferably, said plate is a T shape plated construction; The top board of said plate is a rectangular slab, and said insertion plate is a rectangular slab.
Aforesaid coal-winning machine wheel shaft is prevented unloading device; Preferably; Said bottom of going up socket is provided with arc gap; The said top of socket down is provided with arc gap, and said arc gap and the said arc gap of socket down of going up socket is symmetrical set at interval, and the circular space diameter that is surrounded is greater than the diameter of coal-winning machine gear shaft.
Aforesaid coal-winning machine wheel shaft is prevented unloading device, and preferably, the top of said plate is provided with the link that is used to operate said plate.
Aforesaid coal-winning machine wheel shaft is prevented unloading device, and preferably, the said inserting plate hole that goes up socket and following socket is a rectangular opening.
Aforesaid coal-winning machine wheel shaft is prevented unloading device, and preferably, the bottom of said plate is provided with cross through hole.
Coal-winning machine wheel shaft provided by the invention is prevented unloading device, cooperates with socket on being arranged on coal-winning machine walking box outer wall through plate, and plate is blocked in the outer end of coal-winning machine wheel shaft, thereby can stop the coal-winning machine wheel shaft to be scurried outward.
