According to the fixed pulley block for the bridge crane, sensing weighing devices are mounted between the two ends of the fixed pulley block and a trolley supporting frame, and a steel wire rope is arranged on the fixed pulley block; the fixed pulley block comprises an upper shaft column, the two ends of the upper shaft column are arranged on the sensing weighing device, the two ends, close to the sensing weighing device, of the upper shaft column are sleeved with side yoke plates and positioning rings, the positioning rings are located on the inner sides of the side yoke plates, the inner sides of the lower ends of the side yoke plates are sleeved with lower shaft columns, and connecting plates are arranged at the outer ends of the lower shaft columns. And a pulley is arranged on the lower shaft column. The fixed pulley block has the beneficial effects that the fixed pulley block is additionally provided with the anti-falling cover, the anti-falling cover is used for effectively preventing the problem that the steel wire rope on the side edge jumps out due to softness, the problem that the steel wire rope jumps out of a groove due to the fact that the fixed pulley block is obliquely pulled and hoisted is solved, and the fixed pulley block can make room for additionally installing a weighing metering instrument; and subsequent overhaul, maintenance and verification of the metering instrument by workers are facilitated, and the overhaul and replacement time is shortened.
一种用于桥式起重机的固定滑轮组,固定滑轮组的两端与小车支撑架之间安装有传感称重装置,固定滑轮组上设有钢丝绳;固定滑轮组包括上轴柱,上轴柱的两端设置在传感称重装置上,且上轴柱靠近传感称重装置的两端上套设有侧轭板与定位环,且定位环位于侧轭板的内侧,侧轭板下端的内侧上套设有下轴柱,下轴柱的外端上设有连接板,且下轴柱上设有滑轮。本发明有益效果为:本固定滑轮组通过增加了防脱罩,利用防脱罩有效挡住侧边钢丝绳因松软跳出的问题,不仅解决了定滑轮组因受到歪拉斜吊,导致钢丝绳跳槽的问题,且本固定滑轮组能够为加装称重计量仪器腾出空间,便于工作人员后续的检修、维护及校验计量仪器,减少检修更换时间。
