Description

Two-freedom both arms 90 degree and the 180 difunctional large piece tippers of degree
Technical field
The present invention relates to a kind of tipping arrangement, particularly relate to a kind of 90 degree and plant equipment that 180 degree overturn of carrying out for the large-scale heavy duty part when technique needs, belong to the large-scale accessory machinery in heavy-duty machine manufacturing technology field.
Background technology
" 12 " planning is placed on critical positions revitalizing equipment manufacture, and the weight equipment manufacturing industry is the most important thing of equipment manufacture, it is the industry that concerns economic development and national security, and large-scale, processing and manufacturings super-huge parts are the bases of weight equipment development of manufacturing, it is the basis of the field highly sophisticated products development such as national defence, military project, Aeronautics and Astronautics, be the manufacturing manufacture level of hoisting device and ability, realize that China is by making big country to making the key of making the country prosperous and striding forward.
The large-scale heavy duty part of the special operation conditions such as the extreme size during weight equipment is made, large-tonnage generally needs multiple exchanging position, upset in its mechanical processing process.at present, generally two overhead traveling cranes that utilize the workshop, and by flexible steel cable and attach and realize 90 ° or 180 ° of upsets, but these heavy casting and forgings or spare part outside measurement are larger, can reach 6 meters, substance does not wait from 10 tons-250 tons, because its dimensions is large, weight is large, can produce larger impact because of inertia in switching process, unstable, switching process is restive, exist very large production safety hidden danger, be easy to hurt sb.'s feelings, break the equipment such as big vertical lathe, and easily workpiece is scratched during upset, be difficult to guarantee workpiece surface quality, and the every upset of workpiece once needs for a long time, labor strength is large, efficient is very low, the raising and the whole piece that have seriously restricted crudy are produced the raising of chain production efficiency.
The upset requirement of the goods of industry upset functional adaptation different size, provides technique to carry steadily, effectively at safety, realize with goods by Horizontal revolving change into vertical, will vertically convert to horizontal or realize that 180 spend the operative goals of integrated overturns.The classification of tipper can be classified by the realization of its flip angle, upset object and performance etc.Classify according to maximum flip angle, can be divided into 90 degree tippers and 180 degree tippers; Classify according to the goods of its upset, can be divided into steel coil turning machine, die flip machine and plate turnover etc.; Mainly contain plate chain type suspension motor-driven tipper, hydraulic-driven tipper and quick start continuously tipper etc. according to the realization classification of performance.
Warp is to existing literature search discovery, and the technical data about tipper mainly concentrates on medium and small tipper at present, and less to document or the technical data of large-scale heavy duty tipper.Chinese patent 201020289783.7 discloses a kind of steering frame tilter for passenger car, and this framework tipper is realized upset mainly for H shape and the U-shaped framework of present several principal modes, realizes automation control.Chinese patent 01221217.2 discloses the quick 180 degree tippers of a kind of Automatic continuous, its adopt the air cylinder driven mode can be automatically continuously, fast, accurate location, be mainly used in using on the production logistics line of the industry such as disposable fast food articles for use.Comparative analysis is found, the above disclosed tipper that can realize 180 degree upsets, and it is exactly the upset that its structure or driving pattern can not better be applied to the large-scale heavy duty part that a common deficiency is arranged, and report has 90 degree and the 180 bifunctional tippers of degree.The large-scale heavy duty part is widely used in the industries such as nuclear power, water power, communications and transportation, Aero-Space, manufacturing capacity and the level that its manufacturing capacity and level are directly determining associated equipment, in order to improve the production efficiency of its manufacturing and processing, need to a kind ofly can realize that workpiece can turn over the bifunctional large-scale automatic tipping arrangement that turn 90 degrees, can turn over again turnback.
Summary of the invention
In order to overcome existing tipping arrangement or device above shortcomings, the invention provides a kind of two-freedom both arms 90 degree and the 180 difunctional large piece tippers of degree, this tipper adopts the rolling principle to realize upset, turning large-scale heavy duty workpiece, simple in structure, low cost of manufacture, handling safety, steady.
The technical solution adopted for the present invention to solve the technical problems is as follows:
The present invention mainly comprises base, upper table frame and lower table frame, wherein base is welding structural body, its axial two ends are equipped with the basic roller-way of the arc that is parallel to each other that top is the vertical support plate formation of interior concave arc, be furnished with carrying roller on the basic roller-way of arc, the symmetrical center line of base is provided with drive unit, drives rotor and is provided with driven wheel; Upper and lower Working gantry is semicylinder formula welding structural element, its cylindrical two ends along the circumferential direction are fixedly connected with respectively two semicircular arc supporting tracks, this semicircle supporting track rolls with the basic roller-way of the arc in above-mentioned base and contacts, and realizes carrying, support, positioning function.Respectively be provided with a semicircular arc gear ring parallel with the semicircular arc supporting track in the middle of upper and lower Working gantry, two groups of supporting tracks and middle gear ring on upper and lower two Working gantries stagger the position vertically mutually, above-mentioned two arc gear rings respectively with the engagement of the driven wheel of above-mentioned drive unit; Can realize by add the annexes such as T-shaped parallels, revolution V shape iron, long V shape iron, short V shape iron, oblique V shape iron on upper and lower workbench 90 degree and the 180 degree upsets of the workpiece such as straight tube joint, transition segment, pancake, end socket.Upper table frame and lower table frame are by folding rotating shaft chain connection, and this folding rotating shaft is positioned at the rotary middle spindle overlapping position of car load rotary middle spindle and upper and lower Working gantry.Drive unit in base is delivered to upper and lower Working gantry with motion-promotion force by the semicircular arc gear ring, and then integral body can realize accessible, slow, stable, continuous original place rolling movement, forms to have and completes workpiece turning 90 degree and the 180 difunctional tippers of spending.The upper table frame closes rotating shaft and turns over to turn 90 degrees and open by driving to get around counterclockwise, the upper table frame hangs in part when opening, after closing, upper and lower Working gantry forms a columniform integral body with the workpiece that is reversed, two groups of gear rings and track on two Working gantries of this moment up and down still are positioned at the same face of cylinder, can realize the lift-over that can continue of 180 degree integral body by whole drive system; If upper travelling table locks after opening 90 degree, this moment, the integral cylinder central angle was 270 degree, can realize 90 degree upsets.
The invention has the beneficial effects as follows: the switching mechanism of this tipper integrates 90 degree and 180 degree turn over function, complete function; Adopt the rolling principle to realize the upset of workpiece, bearing capacity significantly strengthens; In switching process, the workpiece gravity self-sealing closes, the convenience that is installed, reliable; This tipper is simple in structure, easily manufactured, with low cost, safe and reliable.
