Description of drawings
Fig. 1 is a kind of hydraulic pressure center support shelf structure schematic diagram that the utility model embodiment provides;
Fig. 2 is that a kind of hydraulic pressure center support frame of providing of the utility model embodiment shown in Figure 1 is along A-A line cutaway view.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, the utility model embodiment is described in further detail below in conjunction with accompanying drawing.
Participate in Fig. 1, hydraulic pressure center support frame of the present utility model mainly is made up of holder, roller, supporting construction and hydraulic test.
Holder 1 middle part is the cube platform, and the left part termination of platform is provided with left column 4, and the right part termination of platform is provided with right column 4, and left and right two columns are identical dual laminated structure.Two columns are contour.Holder is made by firm metal material, and for guaranteeing the stability of whole equipment, holder should be connected with the concrete basis directly or indirectly.
Under holder 1 hydraulic test is installed, its hydraulic test can be selected hydraulic jack or cylinder etc. for use, and hydraulic test selects for use hydraulic jack to realize in the present embodiment.The body 3 and the holder 1 of hydraulic jack are movably connected by suspension plate 2.Piston rod 11 stretches out from hydraulic jack body 3, and can do upper and lower motion, is the positive action parts of the utility model hydraulic pressure center support frame.For realizing the flexible connection of 1 of hydraulic jack body 3 and holder, an end of suspension plate 2 can be fixedlyed connected with holder 1, the other end and hydraulic jack body 3 are hinged; Also an end of suspension plate 2 can be fixedlyed connected with hydraulic jack body 3, the other end and holder 1 are hinged.In the present embodiment, fixedly connected with holder 1 in suspension plate 2 tops, and the bottom is movably hinged by movable axis 12 and hydraulic jack body 3.The mode that adopt to flexibly connect can effectively overcome holder with hydraulic test because position deviation and to the out-of-balance force of hydraulic cylinder piston rod generation, thereby hydraulic test is formed effective protection.
Supporting construction of the present utility model flexibly connects the M shape supporting construction of formation by the left gripper shoe 7 that is double-deck laminated structure, right gripper shoe 8 and left main supporting plate 5, right main supporting plate 6.Top in the double-deck laminated structure of the left column 4 of holder 1 is provided with round nut, while is provided with bearing pin in an end termination of the double-deck laminated structure of left main supporting plate 5, the left main supporting plate 5 of bilayer is put between the double-decker of left column 4, and bearing pin inserted round nut, just the left column 4 of left main supporting plate 5 with holder can be hinged together.Adopt in the same way, also carry out the right column 4 of right main supporting plate 6 and holder hinged.
Another termination of left side main supporting plate 5 and left gripper shoe 7 are carried out hinged, the in addition roller 9 hinged with above-mentioned two structures.Roller 9 is installed in central authorities, is hinged with double-decker left side main supporting plate 5 in the both sides external of roller 9, is hinged with double-deck left gripper shoe 7 again in left main supporting plate 5 both sides external.Adopt the same manner, with right main supporting plate 6, right gripper shoe 8 and 9 rollers also by being hingedly connected together.Two rollers are on sustained height, and roller 9 can freely rotate around jointed shaft, also can relatively rotate between main supporting plate, gripper shoe and the roller.
Between two rollers 9, left gripper shoe 7, right gripper shoe 8 is with to be connected hydraulic jack high pressure piston rod 11 top movable hinged.Piston rod 11 is connected with double-deck right gripper shoe 8 and double-deck left gripper shoe 7 in turn in the center in the outside of piston rod 11.The motion of hydraulic cylinder piston rod 11 directly acts on left gripper shoe 7 and right gripper shoe 8, and drives two gripper shoe motions.
By said structure, form the flexible connection between holder and the main supporting plate; Flexible connection between main supporting plate and gripper shoe and the roller; And the flexible connection between two gripper shoes and the piston rod.
In the tubing process, tubing to be processed is placed between two rollers 9 of hydraulic pressure center support frame of the present utility model.Adjust piston rod 11 and left and right gripper shoe 7,8 hinge tie-point relative positions, hydraulic cylinder piston rod 11 is being stretched out under the state fully, and the home position of two rollers 9 lays respectively on the line at tubing to be processed 10 centers of circle and holder column 4 hinged centers.
Pass through force analysis, when the home position of two rollers 4 lays respectively on the line at tubing to be processed 10 centers and holder column 4 hinged centers, the power of tubing to be processed can be decomposed by left main supporting plate 5 and right main supporting plate 6 in theory, and the power that acts on the piston rod 11 is zero, promptly reaches " self-stabilization " state.Even in the process of tubing 10 being carried out thread turning, produced unbalanced alternate stress, because of this power also can fully be decomposed by left main supporting plate 5 and right main supporting plate 6, so there is not excessive masterpiece to be used on the hydraulic cylinder piston rod 11.
After finishing tubing thread turning operation, reduce the extension elongation of hydraulic cylinder piston rod 11, the tubing 10 that processes can be taken off from hydraulic pressure center support frame of the present utility model smoothly.
M shape supporting construction by left and right main supporting plate and the hinged formation of left and right gripper shoe of the present utility model; and the movable connection method between the supporting construction, holder, piston rod; solved the problem that hydraulic test directly bears excessive pressure; protect hydraulic test to the utmost, prolonged the service life of hydraulic test.Simultaneously, hydraulic test and holder are flexibly connected by suspension plate, can effectively overcome the out-of-balance force that holder and hydraulic test produce owing to position deviation, thereby hydraulic test is formed effective protection.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
