The invention discloses a braking drum brake device for an engineering vehicle. The braking drum brake device comprises a brake disc and a shell, wherein the brake disc is fixedly mounted on a vehicle frame; the shell is fixedly mounted on a wheel; the brake disc is rotationally sleeved with the shell; shaft holes are formed in the center of the shell and the center of the brake disc; a brake cavity is formed in the brake disc; two brake pads which are arranged in a bilaterally symmetric way are arranged in the brake cavity; two brake pad shells are attached to side walls; and abrasion reminding devices are arranged between the brake pads and the shells. A V-shaped brake strip is matched with a V-shaped groove, and the braking function can be completed after the V-shaped brake strip is attached to the V-shaped groove. Fixing strips are matched with reminding belts; when the brake strip is seriously abraded, the distance between the brake pads and the side walls of the brake disc is reduced; and when the fixing strips make contact with the reminding belts, a warning tone can be given out to remind a user to replace the brake strip.

    本发明公开了一种工程车用制动鼓刹装置,包括刹车圆盘和壳体,刹车圆盘固定安装在车架上,壳体固定安装在车轮上,壳体转动套接在刹车圆盘的外部,壳体和刹车圆盘的中心均开设有轴孔,刹车圆盘的内部设有刹车腔,刹车腔的内部设有两个左右对称布置的刹车片,两个刹车片壳体与侧壁之间相贴合,刹车片与壳体之间设有磨损提醒装置。本发明通过V型刹车条V型凹槽相适配,贴近后即可完成刹车功能;本发明固定条和提醒带相适配,当刹车条磨损严重时,刹车片和刹车圆盘侧壁之间的距离减少,当固定条和提醒带接触后,会发出提示音,提醒使用者更换刹车条。
