为了解决煤田地质勘探机械设备修理中装吊的种种困难,湖南第一煤田地质勘探队机修厂钳工组制成了室内简易桥式行车。过去,修理千米钻机、泥浆泵,全靠肩扛棍撬,劳动强度大,修理速度慢,而且不安全。使用桥式行车后,节省了人力,缩短了机械设备的修理时间,操作也比较安全可靠。简易桥式行车的支架、跑轨、横梁架,均用旧岩芯管及金属地梁焊接而成,由三台小
In order to solve the difficulties in loading and unloading of coalfield geological prospecting machinery and equipment, the fitter group of the first coalfield geological prospecting team in Hunan Province made the indoor simple and easy bridge driving. In the past, it repaired a kilometer drilling rig and a mud pump, which ran through the crowbar, which was labor-intensive, slow to repair, and insecure. The use of bridge driving, saving manpower, shorten the repair time of mechanical equipment, the operation is relatively safe and reliable. Simple bridge-type driving carriage, running track, beam frame, are used in the old core tube and welded to the metal beam, from three small
