A kind of prestressed stretch-draw hydraulic jack suspention mobile device provided by the invention, by adopting the combination of multiple triangular frame structures, can be easily completes the suspention, lifting, movement of prestressed stretch-draw hydraulic jack and with regard to bit manipulation by manual operation.The present invention is simple in structure, flexible operation, safe and efficient, economic and practical.Be particularly useful for the girder pre-stressed stretching construction of large bridge T.Compared with adopting the scheme of door machine, the present invention has saved the One-Shift Costs of the mechanical equipment such as a large amount of cranes, door machine, has improved operating efficiency, has good application and promotional value.Compared with self-control derrick column, construct more easy, reduce labour intensity.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example, the invention will be further described:
Fig. 1 is integral structure schematic diagram of the present invention.
Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
Fig. 3 is the schematic top plan view of Fig. 1.
In figure: vertical rack 1, rotating shaft 2, gib 3, horizontal seat 4, diagonal brace rod 5, track 6, diagonal ligament frame 7, holder base plate 8, spherical termination 9, lower set collar 10, upper set collar 11, roller trolley 12, bottle gouard moved by hands 13, back-pressure bar 14, anti-draw ring 15, suspension hook 16, T-shaped beam 17.
The specific embodiment
In Fig. 1 ~ 3, a kind of prestressed stretch-draw hydraulic jack suspention mobile device, vertical rack 1 adopts to be welded and fixed with horizontal seat 4 and is connected, and is welded with diagonal brace rod 5, as shown in Figure 3 between vertical rack 1 upper end and horizontal seat 4;
On vertical rack 1, be movably installed with vertical rotating shaft 2, rotating shaft 2 upper ends are provided with gib 3, on gib 3, lifting appliance is installed, between gib 3 and rotating shaft 2, be installed with diagonal ligament frame 7 by welding, the free end of one end of diagonal ligament frame 7 and gib 3 is welded to connect, and the other end and rotating shaft 2 are welded to connect near the position of lower end.Adopt the structure of framework to be convenient to processing.
Structure thus, by manual control lifting appliance, the height that can realize hydraulic jack is in place, can adjust the position of hydraulic jack by the rotation of rotating shaft.Preferred scheme is as in Fig. 3, and described diagonal ligament frame 7 is hollow frame.Structure thus, the hollow part of diagonal ligament frame 7 is just in time the working space of lifting appliance, can not cause interference to lifting appliance.
Preferred scheme is as in Fig. 1 ~ 3, and described horizontal seat 4 is fixedly mounted on T-shaped beam 17 by back-pressure bar 14 and the anti-draw ring 15 of " L " shape.
As shown in Figure 2, described back-pressure bar 14 one end are buckled in the flange plate of T-shaped beam 17, and the other end is connected with T-shaped beam 17 by anti-draw ring 15, and horizontal seat 4 is being positioned between back-pressure bar 14 and T-shaped beam 17.Adopt the structure of back-pressure bar 14 to fix easily horizontal seat 4, avoid punching or anchoring on T-shaped beam 17 beam bodies, and installing/dismounting is all very convenient, is convenient to the present invention's self movement.Especially back-pressure bar 14 can replace part or all counterweight, and this has further reduced the present invention's self mobile difficulty.
Vertical rack 1, horizontal seat 4 and diagonal brace rod 5 form one group of triangular supports, rotating shaft 2, gib 3 and diagonal ligament frame 7 also form one group of triangular supports, preferably, described vertical rack 1 is triangular supports, has promoted bulk strength and stability like this by the combination of multiple triangular supports.
Preferred scheme is as in Fig. 1, and described rotating shaft 2 is flexibly connected with vertical rack 1 by upper set collar 11 and lower set collar 10;
The bottom of rotating shaft 2 is provided with spherical termination 9, and on horizontal seat 4, corresponding position is provided with holder base plate 8, and holder base plate 8 is provided with the arc groove coordinating with spherical termination 9.Structure thus, rotating shaft 2 stressed more reasonable, has further increased intensity, by the spherical termination 9 that arranges and the combination of holder base plate 8, decompose along the axial force of rotating shaft 2, therefore, upper set collar 11 and lower set collar 10 only need bearing radial force, and this has extended the service life of upper set collar 11 and lower set collar 10, and holder base plate 8 is positioned on basis, also can fine carrying axial force, the arc groove on spherical termination 9 and holder base plate 8, except can be spacing, can also reduce friction.
Further preferred, on gib 3, be provided with track 6, the first-selected channel-section steel of track 6 or I-beam section, track 6 is welded to connect with gib 3, in this example, track 6 is welded on to the upper surface of gib 3, lifting appliance is movably arranged on track 6, and the structure of lifting appliance is: roller trolley 12 is movably arranged on track 6, and the below of roller trolley 12 is connected with bottle gouard moved by hands 13 or electric block.Structure thus, operating personal promotes hydraulic jack except operating bottle gouard moved by hands 13 or electric block, can also roller trolley 12 be slided along track 6 by drag-line, realizes the accurate location of suspension hook 16.
When use, the present invention is located on T-shaped beam 17 beam body two ends panels, fixing firm by the anti-draw ring 15 of back-pressure bar 14 and beam body; The artificial drag-line of adjusting bottle gouard moved by hands 13 or electric block, pulls roller trolley 12, rotating shaft 2, and then realizes the position of adjusting suspension hook 16, thereby it is in place to realize the lifting of hydraulic jack.
