Prevention device with mechanical sensor

拉力传感器防护装置

Abstract

本实用新型拉力传感器防护装置,属起重机设施领域,本装置由上下连接杆和夹板组成,拉力传感器对应置于夹板的凹槽中,上连接杆上端头与吊臂头部连接,上连接杆之下端部与夹板槽上端面刚性接触,其下端头与拉力传感器上端连接;下连接杆的上部与夹板槽下端面有可调节间隙,其上端头与拉力传感器下端连接,其下端头与吊钩连接,上连接杆下端圆盘设计显著增强了承力的作用,下连接杆上部与夹板下方的可调节连接间隙可防止加载重物时装置所产生的形变过大对夹板的损坏,因此,当拉力传感器连接螺栓断裂或者松脱时,夹板可以继续连接上下连接杆,从而防止重物溜钩或者脱钩现象的发生。而且,本实用新型制作简单,安装拆卸方便,实用性强。
The utility model relates to a prevention device with a mechanical sensor, and belongs to the field of crane facilities. The prevention device comprises an upper connecting rod, a lower connecting rod and a clamp plate, wherein the mechanical sensor is correspondingly arranged in the groove of the clamp plate; the upper end head of the upper connecting rod is connected with the head of a suspension arm; the lower end part of the upper connecting rod is in rigid contact with the upper end surface of the clamp plate groove; the lower end head of the upper connecting rod is connected with the upper end of the mechanical sensor; an adjustable gap is formed between the upper part of the lower connecting rod and the lower end surface of the clamp plate groove; the upper end head of the lower connecting rod is connected with the lower end of the mechanical sensor; the lower end head of the lower connecting rod is connected with a lifting hook; a disc is designed at the lower end of the upper connecting rod, so as to enhance the bearing strength remarkably; and the adjustable connecting gap between the upper part of the lower connecting plate and the lower part of the clamp plate can avoid damage on the clamp plate when the deformation on the prevention device is over large during a weight loading process. Therefore, when the connecting bolt of the mechanical sensor is fractured or gets loose, the clamp plate can be connected with the upper and the lower connecting rods continuously to avoid the phenomenon of hook slipping or unhooking of a weight. Moreover, the prevention device is simple to manufacture, convenient to mount and disassemble, and high in practicability.
