Abstract
The utility model discloses a sleeve workpiece hoisting tool, which comprises supporting seats, supporting rods, a fixing support, a hanging ring, lug boards and adjusting screws, wherein the hanging ring is fixed onto the fixing support, the adjusting screws are arranged on the supporting rods, the lug boards are arranged on the fixing support, one end of each supporting rod is hinged with the corresponding supporting seat through a bulb of the corresponding adjusting screw, and the other end of each supporting rod is hinged with the corresponding lug board on the fixing support. The sleeve workpiece hoisting tool adopts three-point support, thereby being stable in hoisting; the supporting rods are adjustable in length within a certain range through threads, and accordingly, hoisting of a sleeve within a certain diameter range can be adapted, and an optimal angle is kept between the axis of each supporting rod and the axis of the fixing support by means of adjustment, so that good operating state is kept; and the supporting rods hinged with the fixing support through pins can freely vertically swing, so that the hoisting tool has the functions of free folding and unfolding, and hoisting is facilitated.
Description
Technical field
The utility model relates to a kind of sleeve work piece hoisting instrument.
Background technology
Slip-type expansion joint is one of leading product of my company's compensator product, and the core pipe is the core parts of sleeve expansion joint, and outer cylinder surface need pass through fine limit work; Luminosity also has higher requirements, still, and core pipe manufacturer technology more complicated; Operation is more, from blanking--roll--welding--the school circle--prtreatment--fine limit work--surface grinding or press polish--chromium plating--surface polishing, assembling procedure is also many;--core pipe and coat suit--inner end packing or the assembling of die-pressed graphite ring--gland packing assembling--outer end packing or the assembling of an a die-pressed graphite ring--ring assembling--loops welded--inspection--friction force test--pressure test--surface treatment etc. like core pipe and seal ring suit; Through so many operation, need repeatedly turnover and repeatedly lifting, the core pipe that precision and finish the are had relatively high expectations scuffing that is easy to collided with; Particularly chromium plating is until arriving the last many operations of pressure testing of product; Core pipe or compensator are whole, all need vertical lifting, directly are stuck in the movable end of core pipe with common suspender; The core pipe outer cylinder surface is here directly gone up scar by card, has seriously influenced the sealing property of compensator.
The utility model content
The purpose of the utility model provides a kind of sleeve work piece hoisting instrument.
The utility model for realizing the technical scheme that above-mentioned purpose adopted is: a kind of sleeve work piece hoisting instrument; Comprise supporting seat (1), strut bar (2), fixed bearing (4), suspension ring (5), otic placode (6) and adjusting screw(rod) (8); Said suspension ring (5) are fixed on the fixed bearing (4); Adjusting screw(rod) (8) is arranged on the strut bar (2); Otic placode (6) is arranged on the fixed bearing (4), and an end of strut bar (2) is hinged through the bulb and the supporting seat (1) of adjusting screw(rod) (8), and the other end is hinged on the otic placode (6) on the fixed bearing (4) through bearing pin (3).
Said adjusting screw(rod) (8) is provided with locknut (7).
Said supporting seat (1) is provided with the sphere that matches with the bulb of adjusting screw(rod) (8).
The bulb of said adjusting screw(rod) (8) is located through spherical gland in the sphere of supporting seat (1).
Said otic placode (6) is three and is evenly distributed on the circumference of fixed bearing (4) upper edge.
Said supporting seat (1) is free to rotate in the certain angle scope.
Said strut bar (2) can swing up and down in certain angular range around bearing pin (3).
A kind of sleeve work piece hoisting of the utility model instrument adopts 3 supports, and lifting steadily; Strut bar length is adjustable in certain scope through screw thread, can adapt to the lifting of certain diameter scope sleeve pipe, and through regulating, can make strut bar axis and permanent seat axis keep best angle, keeps the works fine state; Strut bar is hinged through bearing pin and fixed bearing, can freely swing up and down, and makes lifting device have the function of freely drawing in and strutting, and realizes the purpose of convenient lifting; Hinged between supporting seat and the strut bar through bulb, can rotate freely, reach the purpose that supporting seat and internal surface of sleeve pipe are contacted fully, keep the reliability of lifting; The processing of supporting seat running surface has the reticulate pattern flank of tooth, and through hardening processing, strengthens the friction force and the resistance to abrasion that improves the supporting seat running surface of supporting seat and internal surface of sleeve pipe, keeps the lifting function of lifting device permanently effective.
Description of drawings
Fig. 1 is the structural representation of a kind of sleeve work piece hoisting of the utility model instrument.
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment
As depicted in figs. 1 and 2, sleeve work piece hoisting instrument comprises supporting seat 1, strut bar 2, fixed bearing 4, suspension ring 5, otic placode 6 and adjusting screw(rod) 8; Suspension ring 5 are fixed on the fixed bearing 4, and adjusting screw(rod) 8 is arranged on the strut bar 2, and otic placode 6 is arranged on the fixed bearing 4; One end of strut bar 2 is hinged through the bulb and the supporting seat 1 of adjusting screw(rod) 8, and the other end is hinged on the otic placode 6 on the fixed bearing 4 through bearing pin 3, and adjusting screw(rod) 8 is provided with locknut 7; Supporting seat 1 is provided with the sphere that matches with the bulb of adjusting screw(rod) 8, and the bulb of adjusting screw(rod) 8 is located through spherical gland in the sphere of supporting seat 1, this lifting device; Have suspension ring 5 on the fixed bearing 4,, can be connected with hoist lifting hook as the Heave Here; Supporting seat 1 is hinged with the supporting seat that has sphere through the bulb on the adjusting screw(rod) on the strut bar 8, and both are by sphere gland 9 location, and supporting seat can freely rotate within certain angular range; Play the effect that automatically regulating supporting seat driving surface and internal surface of sleeve pipe contact fully, the supporting seat running surface is processed with toothed surface, and hardens through bakingout process; Guarantee supporting seat ability actv. incision internal surface of casing; Strengthen friction force, three of fixed bearing upper edge circumference rectangular distributions are otic placode 6 fixedly, through bearing pin strut bar is hinged on the permanent seat; Strut bar can swing up and down within certain angular range around bearing pin, plays the effect that suspension bracket is drawn in and struts; Because the axis of strut bar and the axis angle of permanent seat are less than 90 °; When lifting, because the friction force effect of supporting seat and tube wall, axis and the angle between the permanent seat that forces strut bar increases (pass through and adjust the axis that remains strut bar and the angle between the permanent seat axis less than 90 °) to 90 ° of directions; At this moment; Under the effect of lifting force, on supporting seat and inner surface of tube wall, produced a contact pressure along the strut bar axis direction, thereby increased the friction force of supporting seat and tube wall greater than several times of lifting forces; Thereby workpiece is unlikely to slip phenomenon when having guaranteed lifting, has reached the purpose of smooth lifting workpiece.
