The specific embodiment
With reference to accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, the utility model mainly is made up of girder 1, auxiliary girder 3, column 6, front stretching piece 2, the flexible piece 5 in back, passing oil cylinder 4.Be respectively equipped with a horizontal guide slot and a vertical T type gathering sill that distributes up and down in girder 1 front portion, both sides, rear portion; Be respectively equipped with a vertical T type gathering sill and a horizontal guide slot that distributes up and down in auxiliary girder 3 front portions, both sides, rear portion; Front stretching piece 2 is made up of block I 9, spacer pin 10, T connector I 11, lifting ram 12, and the horizontally-guided head in block I 9 left sides forms horizontal sliding with girder 1 horizontal guide slot and is connected, and is used to guarantee the mutual changing of the relative positions in the horizontal direction of girder 1, auxiliary girder 3; The head of T connector I 11 constitutes the vertical slippage with the vertical T type gathering sill of auxiliary girder 3 and is connected, and is used to guarantee the mutual changing of the relative positions on vertical of girder 1, auxiliary girder 3; The shank portion of T connector I 11 is inserted into the inside of block I 9, and lifting ram 12 is arranged in the cavity of resorption of block I 9, and two ends are hinged with block I 9 and T connector I 11 respectively, and it is flexible in block I 9 to handle T connector I 11, is used to control the support tuning; The flexible piece 5 in back is compared with front stretching piece 2, and except that being provided with the ear seat in block II 13 front sides, other part-structures are identical, and the placement direction of the flexible piece 5 in back is opposite with front stretching piece 2 in the work; It is hinged to pass oil cylinder 4 one ends and auxiliary girder 3 right plates, and the other end is hinged with the block II 13 of the flexible piece 5 in back, is used to control the mutual changing of the relative positions in the horizontal direction of girder 1, auxiliary girder 3, realizes moving frame.
Before contiguous block 7, back contiguous block 8 structures identical, form by block III 14, T connector II 15, spacer pin 10, T connector II 15 can freely be stretched in block III 14, stroke is subjected to the Position Control of spacer pin 10, but be used for the connection between a plurality of independence tuning hydraulic prop for moving suspended top beam, but can be adapted to the tuning hydraulic prop for moving suspended top beam and fall frame, move frame, transfer actions such as frame, because but it fuses a plurality of independence tuning hydraulic prop for moving suspended top beam, but constitute the suspended back timber sectional shelf-unit of tuning, can effectively prevent down frame.
