The invention discloses a shaft derrick head sheave, which comprises a lifting mechanism, a head sheave body, an oil storage part arranged on the head sheave body, a power part arranged on the head sheave body, an extrusion part arranged in the oil storage part, a spraying part arranged between the oil storage part and the head sheave body, and a pressurizing mechanism, comprising an inertia part arranged on the head sheave body and a piston part arranged in the inertia part. According to the shaft derrick head sheave, when the head sheave body finishes winding and unwinding of a steel wire rope, due to inertia, the counterweight handle continues to rotate by a certain distance, so that the piston block is driven to move along the annular frame, reciprocating motion of the piston block pressurizes the interior of the extrusion part, maintenance oil in the oil storage tank is sprayed to the surface of the steel wire rope through the atomization spray head, automatic spraying is achieved, and labor force is not needed; no extra power source is needed, the service life of the steel wire rope is prolonged, the maintenance interval time of the steel wire rope is prolonged, and the manual maintenance frequency is reduced.
本发明公开了一种竖井井架天轮,包括,提升机构,包括天轮本体,设置于所述天轮本体上的储油部,设置于所述天轮本体上的动力部,设置于所述储油部内的挤压部,设置于所述储油部与天轮本体之间的喷涂部,加压机构,包括设置于所述天轮本体上的惯性部,设置于所述惯性部内的活塞部。该竖井井架天轮,当天轮本体收放钢丝绳结束时,由于惯性,配重把手继续转动一段距离,从而带动活塞块沿着环形框移动,活塞块的往复运动对挤压部内加压,使储油箱内的维护油通过雾化喷头喷涂至钢丝绳的表面,自动喷涂,不需要劳动力,且不需要额外动力源,增加钢丝绳的使用寿命,增加钢丝绳维护的间隔时间,减少人工维护次数。
