The invention discloses a reciprocating pump gear shield and a hoisting structure, and relates to the field of petroleum engineering equipment. The reciprocating pump gear shield specifically comprises a shield seat, a shield cover, a bolt group, a shield seat lifting appliance, a shield cover lifting appliance and the like, and is characterized in that the ratio of the oil inlet cross sectional area to the oil outlet cross sectional area of the gear shield is proper, sealing pressure of lubricating oil to the gear shield is reduced, various kinds of bosses and plates are connected in an overlapping manner, the inner circles and the outer circles of the bosses and the plates adopt fillet welds, a connecting plate and a bottom plate of the shield seat are made of an integral steel plate material, welding and drilling are carried out firstly, then the integral steel plate material is cut into two parts, materials are saved, the end face does not need to be machined after welding, proper sealing is adopted for cooperation, reliable sealing is ensured, no negative pressure exists in the gear shield, atmospheric water can enter the gear shield, the long service life of a large and small gear pair is guaranteed, an oil inlet and an oil outlet of the gear shield are hidden, the shield is attractive in appearance, the shield seat lifting appliance is arranged on the gravity center line of the shield seat, the shield cover lifting appliance is arranged on the gravity center line of the shield cover, and the shield seat and the shield cover are safe, easy and convenient to assemble.

    本发明公开了一种往复泵齿轮护罩及吊装结构,涉及石油工程设备领域,具体包括护罩座、护罩盖、螺栓组、护罩座吊具、护罩盖吊具等,特色是齿轮护罩的进油和出油横截面积比例适当,降低润滑油对齿轮护罩各密封压力,各种凸台和板的连接采用重叠形式,凸台内外圆与板采用角焊缝,护罩座的连接板和底板是一个整体钢板材料,先焊接和钻孔、然后切割分成两部分,节约材料、焊接后端面不需加工,配合适当密封,确保密封可靠,齿轮护罩内无负压,大气水分不能进入,保证大小齿轮副的长寿命,齿轮护罩的进油口和出油口隐蔽,护罩外形美观,护罩座吊具在护罩座的重心线上,护罩盖吊具在护罩盖的重心线上,装配护罩座和配罩盖时安全、轻松和方便。
