The invention belongs to the field of winch braking mechanisms, and particularly relates to a workover rig winch braking mechanism which comprises a vehicle body, a workover rig is rotationally connected to the right side of the vehicle body, a winch is fixedly installed on the top of the vehicle body, a cable is arranged on the winch in a sleeving mode, and the cable is matched with the workover rig. A positioning mechanism and a braking mechanism are arranged at the top of the vehicle body, a detecting mechanism and a speed reducing mechanism are arranged on the front side of the workover rig, the positioning mechanism comprises a gear, a fixing frame, a rack, a round rod and an extension spring, the gear is fixedly installed on the front side of the winch, the fixing frame is fixedly installed at the top of the vehicle body, and the rack is slidably connected to the inner side of the fixing frame; the winch can be emergently braked by starting the first electric push rod, and the cable can be decelerated by starting the second electric push rod, so that the situation that the cable rapidly descends to injure nearby workers is avoided, and accidents are avoided.

    本发明属于绞车制动机构领域,尤其是一种修井机绞车制动机构,现提出如下方案,其包括车体,所述车体的右侧转动连接有修井机,车体的顶部固定安装有绞车,所述绞车上套设有缆绳,缆绳与修井机相配合,车体的顶部分别设有定位机构和制动机构,修井机的前侧设有检测机构和减速机构,所述定位机构包括齿轮、固定架、齿条、圆杆和拉伸弹簧,齿轮固定安装在绞车的前侧,固定架固定安装在车体的顶部,齿条滑动连接在固定架的内侧,本发明通过启动第一电动推杆,第一电动推杆就可对绞车进行紧急制动,再启动第二电动推杆,第二电动推杆就可对缆绳进行减速,避免缆绳快速的下降,来对附近的工作人员造成伤害,避免意外的发生。
