The invention relates to the technical field of transfer vehicles, in particular to a transfer vehicle with a normally-closed brake mechanism, the normally-closed brake mechanism comprises a gear brake outer ring, a gear brake inner ring and a sliding sleeve, the gear brake outer ring synchronously rotates along with a directional wheel, the sliding sleeve is fixedly connected with an axle, and the gear brake inner ring slidably sleeves the sliding sleeve; the opposite end faces of the tooth brake inner ring and the tooth brake outer ring are provided with protrusions and grooves. The normally-closed brake mechanism further comprises a push rod assembly and a brake handle, the push rod assembly comprises a fixing shell, a push rod and an elastic piece, the first end of the push rod is connected with the tooth brake inner ring, and the brake handle is in transmission connection with the second end of the push rod through a brake cable. The normally-closed brake mechanism can be matched with a frame, an axle and a tire structure of the transfer trolley, and compared with an existing trolley of a simple structure, heavy goods can be transferred; and meanwhile, under the condition that transportation personnel do not operate a brake handle, the brake mechanism is in a normally-closed brake state, and accidents caused by vehicle movement can be avoided.
本发明涉及转运车技术领域,具体涉及一种具有常闭式制动机构的转运车,常闭式制动机构包括齿刹外圈、齿刹内圈及滑套,齿刹外圈随定向轮同步转动,滑套与车轴固定连接,齿刹内圈滑动套设在滑套外部,齿刹内圈与齿刹外圈的相对端面上设有凸起和凹槽;常闭式制动机构还包括推杆组件和刹车手柄,推杆组件包括固定壳、推杆及弹性件,推杆的第一端与齿刹内圈连接,刹车手柄通过刹车线与推杆的第二端传动连接。本发明中常闭式制动机构能够与转运车的车架、车轴和轮胎结构适配,相比现有简单结构的手推车,可以转运重型货物;同时在运输人员不操作刹车手柄的情况下,制动机构均处于常闭式的制动状态,能够避免车辆移动而发生意外事故。
