Abstract
The utility model relates to techniques of pulling motor pulleys, in particular to a safety wheel puller. The safety wheel puller comprises a central bar, a bearing beam, a pull plate, a protective bar, a nut, a pull chain and a clamping plate. The safety wheel puller is in a rectangular truss structure. The top end of the central bar is hexagonal. A shank of the central bar is provided with an external thread. The lower end of the central bar is tipped. The bearing beam is rectangular. The thickened middle of the bearing beam is provided with an internal threaded hole matching with the central bar. A sheath is disposed in the middle of the protective bar, and a pressure bearing is disposed inside the sheath. Screws are disposed at two ends of the protective bar, and nuts are screwed on the screws. The central bar penetrates through the middle sheath of the protective bar. The pull plate is rectangular and symmetrical. The top, middle and bottom of the pull plate are provided with three rectangular through holes on a same plane respectively. Two ends of the bearing beam, two ends of the protective bar and two ends of the clamping plate penetrate through the top, middle and bottom through holes of the pull plate respectively. The protective bar is locked through a nut after penetrating. The pull chain is disposed at the lower end of the pull plate, a hook is disposed in the middle of the pull plate, and the hook is hooked to a lifting ring of the motor. The clamping plate of the safety wheel puller is in a two-semicircle structure and is provided with a central hole, and rectangular lateral handles are arranged on two sides of the clamping plate. A pulley is locked by the clamping plate, and the area of contact of the pulley with the safety wheel puller is enlarged.
Description
Technical field
The utility model relates to motor pulley puller technology, specifically a kind of safety-type pulley extractor.
Background technology
In the daily Oil wells management of field produces, transfer the work of ginseng and replacing motor more and more frequent.Because motor and belt pulley gap are little, the pawl of conventional pulley extractor is put to be entered.Motor is in outdoor operation for a long time, there is serious corrosion problem, add reverse fastening in motor shaft and the belt pulley long time running, causing motor pulley to be dismantled extremely wastes time and energy (the outstanding difficult dismounting of flat axle), the existing trochus of taking off is often taken off rim of pulley bad, belt is damaged easily, and also there is potential safety hazard in easy distending.Not only cause Master Cost to increase, and affect crude oil production.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, designs a kind of safety-type pulley extractor.
The utility model is realized by following technical proposals:
The utility model comprises: center-pole, load beam, tension board, fender rod, nut, slide fastener, clamp.Its safety-type pulley extractor is the rectangle truss structure, the center-pole top is provided with six sides, the body of rod is provided with external screw thread, the lower end is provided with top, the load beam is cuboid, and middle thickening is provided with internal thread hole and cooperates with center-pole, and the fender rod center is provided with sheath, pressure bearing is housed in the sheath, two ends are provided with screw rod, are rotary with nut, and center-pole passes from the fender rod central sheath, tension board is cuboid, be symmetrical structure, on, in, a lower rectangular through holes, the load beam of respectively having at grade, fender rod, respectively upper from tension board of the two ends of clamp, in, lower three through holes pass, after fender rod passes, by nut check.The lower end of tension board is provided with slide fastener, and the centre is provided with hook, hangs on the suspension ring of motor.
Clamp in the above-mentioned safety-type pulley extractor is two semicircle structures, is provided with centre bore, and both sides are provided with the cuboid ear handle.Clamp blocks belt pulley, has increased the contact-making surface between belt pulley and the pulley extractor.
The beneficial effects of the utility model are: simple in structure, easy to operate, safe and reliable, adapt to the flat axle of all size, tapering belt pulley, and prevent that belt from damaging, the economical with materials expense, time saving and energy saving, alleviate workman's labour intensity, increase crude output.
Description of drawings
Fig. 1-the utility model master TV structure schematic diagram.
The plan structure schematic diagram of clamp 7 among Fig. 2-Fig. 1.
Among the figure, 1. center-pole, 2. load beam, 3. tension board, 4. fender rod, 5. nut, 6. slide fastener, 7. clamp; D. centre bore.
The specific embodiment
Below in conjunction with accompanying drawing enforcement of the present utility model is further elaborated:
The utility model is comprised of center-pole 1, load beam 2, tension board 3, fender rod 4, nut 5, slide fastener 6, clamp 7.Its safety-type pulley extractor is the rectangle truss structure, center-pole 1 top is provided with six sides, the body of rod is provided with external screw thread, the lower end is provided with top, the 2 middle thickenings of cuboid load beam are provided with internal thread hole and cooperate with center-pole 1, in fender rod 4 central sheath pressure bearing is housed, the two ends screw rod is rotary with nut 5, center-pole 1 passes from fender rod 4 central sheath, cuboid tension board 3 is symmetrical structure, on, in, a lower rectangular through holes, the load beam 2 of respectively having at grade, fender rod 4, respectively upper from tension board 3 of the two ends of clamp 7, in, lower three through holes pass, and are provided with hook in the middle of the lower end slide fastener 6 of tension board 3.
