A kind of prestressed stretch-draw hydraulic jack suspention mobile device provided by the invention, by adopting the combination of multiple triangular frame structure, can complete the suspention of prestressed stretch-draw hydraulic jack, lifting, movement and with regard to bit manipulation conveniently by manual operation.Structure of the present invention is simple, 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, present invention saves the One-Shift Costs of the mechanical equipment such as a large amount of crane, door machine, improve operating efficiency, there is application and promotional value preferably.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, reverse drawing ring 15, suspension hook 16, T-shaped beam 17.
Detailed description of the invention
As 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;
Vertical rack 1 is movably installed with vertical rotating shaft 2, rotating shaft 2 upper end is provided with gib 3, gib 3 is provided with lifting appliance, diagonal ligament frame 7 is installed with by welding between gib 3 with rotating shaft 2, one end of diagonal ligament frame 7 and the free end of gib 3 are welded to connect, and the other end and rotating shaft 2 are welded to connect near the position of lower end.The structure of framework is adopted to be convenient to processing.
Structure thus, by manual control lifting appliance, the height that can realize hydraulic jack is in place, can be adjusted 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 the back-pressure bar 14 of " L " shape and reverse drawing ring 15.
As shown in Figure 2, described back-pressure bar 14 one end is buckled in the flange plate of T-shaped beam 17, and the other end is connected with T-shaped beam 17 by reverse drawing 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 secure horizontal seat 4 easily, avoid punching or anchoring on T-shaped beam 17 beam body, and installing/dismounting is all very convenient, is convenient to the movement of the present invention self.Especially back-pressure bar 14 can replace part or all counterweight, This further reduces the mobile difficulty of the present invention self.
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, improves 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 coordinated with spherical termination 9.Structure thus, rotating shaft 2 stressed more reasonable, further increases intensity, by the combination of the spherical termination 9 that arranges and holder base plate 8, decompose the axial force along rotating shaft 2, therefore, upper set collar 11 and lower set collar 10 only need to bear diametral load, and this extends the service life of set collar 11 and lower set collar 10, and holder base plate 8 is positioned on basis, also can carry axial force very well, the arc groove on spherical termination 9 and holder base plate 8 except can spacing except, can also friction be reduced.
Preferred further, gib 3 is provided with track 6, the first-selected channel-section steel of track 6 or I-beam section, track 6 and gib 3 are welded to connect, in this example, track 6 is welded on 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, except can operating bottle gouard moved by hands 13 or electric block lifting hydraulic jack, can also make roller trolley 12 slide along track 6 by drag-line, realize the accurate location of suspension hook 16.
During use, the present invention is located on the panel of T-shaped beam 17 beam body two ends, fixing firm by back-pressure bar 14 reverse drawing ring 15 and beam body; The drag-line of artificial adjustment bottle gouard moved by hands 13 or electric block, pulls roller trolley 12, rotating shaft 2, and then realizes the position of adjustment suspension hook 16, thus the lifting realizing hydraulic jack is in place.
