Abstract
The utility model discloses a wheel remover which is composed of pull claw rods, a drawing base and a screw jack. A through hole and three adjusting holes are formed in the drawing base, pull claws are arranged at the upper ends of the pull claw rods, threaded rod bodies are arranged at the lower ends of the pull claw rods, and the three pull claw rods are located in the adjusting holes respectively and fixed onto the drawing base through nuts and gaskets. The screw jack is composed of a transmission handle, a piston screw and a screw jack cylinder, the piston screw is arranged on the upper portion of the screw jack cylinder, and the transmission handle is arranged on the lower portion of the screw jack cylinder; the screw jack cylinder is fixed to the lower end of the drawing base, and the piston screw is located in the through hole. The wheel remover has the advantages that the pull claw rods are long in movement distance, the pull claws are large in width, and the wheel remover is simple in structure, small in size, low in cost, convenient to use, stable in operation, safe, reliable and capable of being widely used for disassembling a transmission wheel from a transmission shaft.
Description
Technical field
The utility model relates to a kind of mechanical provision for disengagement, more specifically to a kind of pulley extractor that drive is pulled down from power transmission shaft.
Background technology
Drive is as the vitals of transmission mechanism, and in industrial and agricultural production and daily life, application is very general.Drive is generally belt wheel, gear, cam, sprocket wheel etc., it is arranged on motor shaft or power transmission shaft conventionally, due to transmission device descend in the open operation or service time long, easily cause the contact surface of drive and power transmission shaft to produce corrosion, and then generation viscous, drive is disassembled very difficult from power transmission shaft.Traditional method is at operation field, it to be heated, with pulley extractor, disassembled again, this mode has not only increased cost, waste time and energy, and pulling claw bar is difficult for adjusting, inconvenient operation, the width of pulling claw is little, easily the edge of drive is caused to damage, particularly dismantle irregular drive, weak effect.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, easy to use, dismantle effective pulley extractor.
The purpose of this utility model is to be achieved by following technical proposals:
, by pulling claw bar, drawing seat, screw jack, being formed, described drawing seat is provided with through hole and three adjustment holes, the upper end of pulling claw bar is provided with pulling claw, lower end is provided with the screw thread body of rod, and three pulling claw bars lay respectively in adjustment hole, and is fixed on drawing seat with nut and pad; Described screw jack is comprised of driving handle, piston screw, screw jack cylinder, and piston screw is located at the top of screw jack cylinder, and driving handle is located at its underpart; Screw jack cylinder is fixed on the lower end of drawing seat, and piston screw is arranged in through hole.
The bottom of described screw jack cylinder is provided with base plate, and one end of three spaced gripper shoes is separately fixed on drawing seat, and the other end is separately fixed on base plate.
The beneficial effects of the utility model are:
1, the utility model be applicable to corrosion, viscous etc. cause common pulley extractor be difficult to dismounting drive, bearing capacity reaches 15 tons, operation field do not need heating just can directly pull up drive.
2, pulling claw bar operating range of the present utility model is larger, can regulate separately the irregular drive of part, and the width that grasps of its pulling claw is 30mm, is difficult for drive edge to cause damage.
3, the utility model is simple in structure, and volume is little, with low cost, easy to use, and working stability is reliable, and safety coefficient is high, can large-scale promotion use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1.
In figure, be labeled as: 1-driving handle, 2-gripper shoe, 3-nut, 4-pad, 5-piston screw, 6-pulling claw, 7-pulling claw bar, 8-through hole, 9-adjustment hole, 10-drawing seat, 11-screw jack cylinder, 12-base plate.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1 and Figure 2, a kind of pulley extractor, by pulling claw bar 7, drawing seat 10, screw jack, formed, described drawing seat 10 is provided with through hole 8 and three adjustment holes 9, the upper end of pulling claw bar 7 is provided with pulling claw 6, lower end is provided with the screw thread body of rod, and three pulling claw bars 7 lay respectively in adjustment hole 9, and is fixed on drawing seat 10 with nut 3 and pad 4; Described screw jack is standard mechanical product, available on the market.Screw jack is comprised of driving handle 1, piston screw 5, screw jack cylinder 11, and piston screw 5 is located at the top of screw jack cylinder 11, and driving handle 1 is located at its underpart.Screw jack cylinder 11 is fixed on the lower end of drawing seat 10, and for example, one end that the bottom of screw jack cylinder 11 is provided with 12, three spaced gripper shoes 2 of base plate is separately fixed on drawing seat 10, and the other end is separately fixed on base plate 12.Piston screw 5 is arranged in through hole 8.
During work, first piston screw 5 is withstood to the axle head of power transmission shaft, then regulate pulling claw bar 7, at this moment, pulling claw 6 all points to center, and blocks the top edge of the drive that needs dismounting, and then locking nut 3, make drawing seat 10 relative with drive fixing, now, then operate driving handle 1, make piston screw 5 stretch out screw jack cylinder 11, between drive and power transmission shaft, be moved, thus the object that reaches quick, efficiently dismantles drive from power transmission shaft.
The utility model is not limited to above-mentioned embodiment, no matter do any variation in its shape or structure, the structure of the dismounting drive that every employing is comprised of pulling claw bar 7, drawing seat 10, screw jack, within all dropping on the utility model protection domain.
