Abstract
The utility model relates to an equipment maintenance tool, in particular to a hydraulic wheel puller comprising a lifting jack, a jack connector and a fixing frame. The fixing frame comprises a force-bearing connecting screw, an outer disc and an inner disc. The outer disc and the inner disc are fixed through the force-bearing connecting screw in a joint manner, the lifting rack is connected with the outer disc through the jack connector, and a U-shaped open mouth is arranged in the inner disc. Since a separate structure is adopted between a hydraulic device of the hydraulic wheel puller and the fixing frame, the hydraulic wheel puller is easy to carry and convenient to use. Compared with a conventional fixing pawl, the fixing frame has an increased thrust face, and a notch caused by a belt pulley being pulled out is further avoided. The hydraulic wheel puller is both time-saving and labor-saving as compared with that of a mechanical wheel puller, and work efficiency is improved.
Description
Technical field
The utility model relates to a kind of overhaul of the equipments instrument, is specifically related to a kind of hydraulic draw trochus.
Background technology
oil pumper is a kind of oil production equipment that oil extraction system is generally used, rod-pumped well is adjusted jig frequency, normally realize by change motor belt wheel diameter, change diameter pulley and just must change belt pulley, pulley extractor is one of indispensable instrument of changing by belt pulley, the pulley extractor that uses at present is the mechanical type pulley extractor, often use and problem miscellaneous to occur, if belt pulley fills by inner, when pulling out wheel, three pawls of pulley extractor just can't be grabbed in place, can not guarantee enough stress surfaces, operate like this and often can extract breach to the edge of belt pulley, cause the belt pulley damage, some belt pulleys are because key fills tightly or other reasons, often can't extract from motor shaft, be forced to change motor, strengthened cost payout, reduced system effectiveness, and, present material is all network management, if can not in time allocate belt, will extend and stop the well time, delay completing of output.In addition, the use of mechanical type pulley extractor needs the 2 above compounding practices of people, and workload is large, and certain operation skill must be arranged, and difficulty is larger.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of hydraulic draw trochus, and hydraulic means and fixed mount adopt separate type, are easy to carry, and be easy to use.
The technical solution adopted in the utility model is as follows: the hydraulic draw trochus, comprise jack, jack connector and fixed mount, described fixed mount comprises stressed connecting screw rod, outer disc and interior disk, described outer disc and interior disk are connected and fixed by stressed connecting screw rod, described jack is connected with outer disc by the jack connector, and described interior disk is provided with the U-shaped opening.
The utlity model has following beneficial effect: the hydraulic means of hydraulic draw trochus and fixed mount adopt separate type, be easy to carry, easy to use, fixed mount is compared with original fixed claw has the stress surface increase, the phenomenon of breach can not appear belt pulley is extracted again, the hydraulic draw trochus is more time saving and energy saving than mechanical type pulley extractor, has improved operating efficiency.
