Abstract
The invention provides a sealing bend switching device of a double-station vacuum refining system. The sealing bend switching device comprises a sealing bend and a bend moving trolley, and further comprises a bend lifting frame and a jacking mechanism. The jacking mechanism is mounted on the bend moving trolley, and the bend lifting frame is mounted on the jacking mechanism. The sealing bend is connected with the bend lifting frame through flexible ropes. The jacking mechanism drives the bend lifting frame to go up and down so as to drive the sealing bend to move up and down. According to the sealing bend switching device, the sealing bend is connected with the bend lifting frame through four-point hanging of the flexible ropes, and due to the fact that the flexible ropes are short and have certain inclination angles, the swing amplitude of the sealing bend in the moving and lifting process can be controlled, and reliable locating and sealing of the sealing bend in switching are facilitated due to flexible connection. Guiding wheels on the bend lifting frame and guiding columns on the bend moving trolley are matched, and therefore it can be guaranteed that the lifting actions of the sealing bend are stable and reliable.

Embodiment
By particular specific embodiment, embodiments of the present invention are described below, person skilled in the art scholar the content disclosed by this specification sheets can understand other advantages of the present invention and effect easily.
As shown in Figure 1, double-position vacuum rectification systems has three vacuum straight tubes 3 and a sealing bend 4, trolley track 15 central authorities that three vacuum straight tubes 3 are distributed in stationary platform 1 are in line, vacuum straight tube 3 wherein connects vacuum pump system, and all the other two vacuum straight tubes 3 distribute and connect respective vacuum metallurgy treatment unit; Sealing bend 4 connects middle vacuum straight tube 3 all the time, and is connected with one that is doing vacuum refinement in all the other two vacuum straight tubes 3, does corresponding switching when changing process station.
The invention provides a kind of sealing bend 4 shifter of double-position vacuum rectification systems, comprise sealing bend 4 and elbow travelling car 2, also comprise elbow lifting frame 6 and lifting body 5, lifting body 5 is arranged on elbow travelling car 2, elbow lifting frame 6 is arranged on lifting body 5, sealing bend 4 is connected with elbow lifting frame 6 by four chains 9, lifting body 5 drives elbow lifting frame 6 oscilaltion thus slings or put down sealing bend 4, in this example, lifting body 5 is hydro-cylinder, also can be cylinder etc.
In order to miniaturization of the apparatus in this example, elbow lifting frame 6 and lifting body 5 are positioned at below sealing bend 4, so not only can save space but also can shortening chains 9 length.Elbow lifting frame 6 is provided with two supporting seats 7, two supporting seats 7 lay respectively at the both sides in sealing bend 4, and it is symmetrical, each supporting seat 7 is equipped with a pair flap seat 11, two pairs of flap seats 11 are also symmetrically arranged, sealing bend 4 is provided with two to the hanging seat 10 corresponding with flap seat 11, chain 9 upper and lower end is connected with flap seat 11 and hanging seat 10 respectively, forms 4 extensions and hangs.
Flap seat 11 and hanging seat 10 stagger a little, tilt when chain 9 is strained relative to vertical direction.Its angle is 5 °-10 °, and the angle of chain 9 place plane and elbow travelling car 2 direction of motion is 45 °-90 °, and namely in Fig. 2, flap seat 11 is 45 °-90 ° with the angle of elbow travelling car 2 direction of motion.Because chain 9 length is shorter relative to traditional electrical cucurbit and have certain angle of inclination, the amplitude of fluctuation of sealing bend 4 in moving lifting process can be controlled, belong to again simultaneously and flexibly connect, reliably locate when facilitating sealing bend 4 to switch and seal, and be elevated relative to traditional rigidity, better can keep the level of sealing bend 4, avoid when connecting, sealing bad or that contraposition is inaccurate situation.
Conveniently regulate the levelness of sealing bend 4, flap seat 11 is vertically equipped with adjusting screw(rod) 12, and chain 9 upper end is connected with adjusting screw(rod) 12 lower end, and hanging seat 10 comprises ear seat and level and is located in bearing pin on ear seat, and chain 9 lower end is enclosed within bearing pin.
The supporting seat 7 of sealing bend 4 both sides is respectively provided with an assembly guidance, and liner comprises the guidepost 8 that is vertically arranged on elbow travelling car 2 and is arranged on the guiding wheels that elbow lifting frame 6 coordinates with guidepost 8.Guiding wheels comprise the two pairs of guide deflection sheaves 14 in left and right, often pair of guide deflection sheave 14 comprises upper and lower two guide deflection sheaves 14, guide deflection sheave 14 is arranged on supporting seat 7 by mount pad 13, what guidepost 8 outer wall was relative is welded with two V-type plates, and guidepost 8 is through supporting seat 7, guide deflection sheave 14 periphery becomes the V-type of indent, make between guide deflection sheave 14 with guidepost 8 as V-type spigot surface coordinates, can ensure that elbow lifting frame 6 is steadily elevated by guide deflection sheave 14 with coordinating of guidepost 8, for the ease of installing, debugging, guide deflection sheave 14 is arranged on elbow lifting frame 6 by excentric shaft, the position between guide deflection sheave 14 and guidepost 8 can be regulated by the position of eccentric rotation axis.
In order to ensure that connection can lean against elbow travelling car 2 and be provided with off-position limit switch to realize the location of elbow, vacuum straight tube 3 is provided with orienting lug, can further realize effectively locating and sealing when elbow switches in different vacuum pipe systems.Elbow travelling car 2 is provided with four wheels and has two at least for adhesion wheel, traversing between two place's working positions, and can be moved to maintenance position; Power cable and other energy medium link elbow travelling car 2 by towing cable.Elbow travelling car 2 two ends are provided with snubber assembly, and described trolley track 15 two ends are provided with car stop.In other embodiments, chain 9 can be the flexible cables such as cable wire.
Principle of work of the present invention is as follows:
When hydro-cylinder stretches out, bend pipe lifting frame rises, and chain 9 is tightened up, and sealing bend 4 is mentioned from vacuum straight tube 3 flange face; After being transported to specified location by bend pipe travelling car, hydro-cylinder is retracted, and bend pipe lifting frame declines, and chain 9 is relaxed, sealing bend 4 is put back on vacuum straight tube 3 flange face, and sealing bend 4 relies on the caulking gum of conducting oneself with dignity and pushing down between elbow flange and vacuum straight tube 3 flange.Sealing bend 4 of the present invention is connected with elbow lifting frame 6 by chain 9 four-point suspension, because chain 9 length is shorter and have certain angle of inclination, the amplitude of fluctuation of sealing bend 4 in moving lifting process can be controlled, belong to again simultaneously and flexibly connect, reliably locate when facilitating sealing bend 4 to switch and seal.Guide deflection sheave 14 on elbow lifting frame 6 coordinates with the guidepost 8 on elbow travelling car 2, can ensure that sealing bend 4 lifting action is steadily reliable.This device only has one to drive oil cylinder, and structure is simple, and Hydraulic Station does not need to establish synchronizing function, and cost is lower, and structure is simple, and maintenance is little.
Any person skilled in the art scholar all without prejudice under spirit of the present invention and category, can modify above-described embodiment or changes.Therefore, such as have in art usually know the knowledgeable do not depart from complete under disclosed spirit and technological thought all equivalence modify or change, must be contained by claim of the present invention.
