The winch buffer braking device comprises a weighing sensor, a rotating speed sensor and a control box, the weighing sensor is arranged between a heavy object and a crown block, the rotating speed sensor is in transmission connection with a roller shaft on a winch, brake discs are arranged on the two sides of a winch roller, and each brake disc is provided with a brake executing mechanism; a control unit and an information acquisition unit are integrated in the control box, signal lines of the weighing sensor and the rotating speed sensor are connected into the information acquisition unit, the control unit is externally connected with a power mechanism, and the control unit is also externally connected with a brake control button; the output end of the power mechanism is connected with the brake executing mechanism. According to the device, the braking mode can be automatically judged and selected according to the weight of a heavy object hung on the winch and the lowering speed, and buffering braking can be carried out on the winch in various braking states; potential damage to the winch and peripheral structures caused by one-time braking is avoided, and meanwhile the personal safety of operators can be effectively protected.
本发明公开了一种绞车缓冲制动装置,包括称重传感器、转速传感器及控制箱,重物与天车之间设置有称重传感器,转速传感器与绞车上的滚筒轴传动连接,绞车滚筒的两侧设置有刹车盘,每个刹车盘均设置有刹车执行机构;在控制箱内集成有控制单元与信息采集单元,称重传感器、转速传感器的信号线均接入信息采集单元中,控制单元外接有动力机构,控制单元还外接有制动控制按钮;动力机构的输出端与刹车执行机构连接。本发明的装置,能够根据绞车悬挂重物的重量及下放速度自动判断选择刹车方式,多种刹车状态下均能对绞车实施缓冲制动;避免一次制动对绞车及周边结构造成潜在的伤害,同时也能有效保护操作人员的人身安全。
