Abstract
The utility model relates to a slip-type wheel puller and belongs to the technical field of motor belt pulley dismounting devices in various mechanical equipment. The slip-type wheel puller comprises two slips, stress bolts, a jackscrew, a shell base and fixing bolts, wherein the slips take the shape of semi-circular arc, the stress blots and lug plates are arranged on the slips, the two slips are fixed on a belt groove of a belt pulley by the fixing bolts through the lug plates of the slips, a sliding groove is arranged on the shell base, the stress bolts on the two slips penetrate through the sliding groove and are fixed by screw caps, the jackscrew is installed in a center hole of the shell base through screw thread and is propped against a motor shaft, the semi-circular arc slips are clamped in the belt groove of the belt pulley, and the contact area between the semi-circular arc slips and the belt pulley can be increased for avoiding the damage of the belt pulley and connecting equipment in operation, and the working efficiency is enhanced.
Description
Technical field
The utility model relates to a kind of slip-type pulley extractor, belongs to the motor pulley provision for disengagement technical field in the various plant equipment.
Background technology
At present, in the oil recovery process of oil field, when need are extracted the pumping-unit motor belt pulley, the pulley extractor that adopts has two pawls or three-jaw mechanical type pulley extractor, because it is little with the belt pulley contact area, stressed greatly, usually cause pulley extractor two pawls or three-jaw to be pulled off or damage the phenomenon of belt pulley.The disclosed pulley extractor of ZL02234306.7, what use is to pull out wheel plate, pulling out wheel plate is stuck between belt pulley and the motor housing, because the gap between the two is little, especially use very inconvenient at the oil-field oil pumper belt pulley, exist equally that stretching resistance is little, strength is weak, pulley extractor damages easily, does not reach the defective that operation requires.
The utility model content
The purpose of this utility model provides a kind of slip-type pulley extractor, overcomes the defective that pulley extractor stretching resistance of the prior art is little, strength weak, pulley extractor damages easily.
The utility model is made up of two slips, stress bolt, jackscrew, body shell base, set bolt, slips is a semicircular arc, which is provided with stress bolt and otic placode, two slips are fixed in the belt grooves of belt pulley by the otic placode of set bolt by two slips, have sliding tray on the body shell base, the stress bolt on two slips passes sliding tray and by fixed by nut; Jackscrew is installed in the centre bore of body shell base and withstands on the motor shaft by screw thread.
Semicircular arc slips of the present utility model is stuck in the belt grooves of belt pulley, can increase the contact area with belt pulley, avoids causing in operation the damage of belt pulley and connection device thereof, increases work efficiency.
