This device have employed the technique that steel strand cable hydraulic synchronizing lifting device and spin balancing combine, and by passing, carries and to fall and rotation combines together, strengthen the continuity of lifting operation, effectively reduce input amount and the working strength of operating personnel.
The construction method of the hoisting appliance of described large-sized rolling mills frame, comprises the steps:
Step 1, by course lay sliding rail;
Step 2, assembled frame posture bracing frame and bearing beam, wherein, the column of frame-type bracing frame is erected at by piston shoes on sliding rail, and each connecting joint of frame-type bracing frame all connect with high strength bolt;
Step 3, on connecting cross beam erection lift module lift oil cylinder;
Step 4, build suspender, wherein, by assembled for rotating frame in rolling-mill housing, rotating frame and rolling-mill housing bias are assembled, namely the center of lower rotary shaft slightly biased in the center-of-gravity position 350-450mm of rolling-mill housing;
Step 5, use driving hold rolling-mill housing afterbody, prevent rolling-mill housing from rotating, start the slippage of frame-type bracing frame to assigned address;
Step 6, by after rolling-mill housing slippage to desired location, use lift oil cylinder start lift, (till rising to absolute altitude computed in advance, mounting seat and memorial archway holding-down bolt when the height namely promoted is to ensure that rolling-mill housing rotates, can be crossed);
Step 7, lifting start slippage limit, limit and rotate after putting in place, rolling-mill housing moved in respective seat, and make rolling-mill housing reach plumbness;
Step 8, rotate to after plumbness until rolling-mill housing, lift oil cylinder starts to decline and rolling-mill housing is in place, tightens holding-down bolt.
This device and construction method improve alerting ability and the reliability of on-site hoisting operation and construction organization, the input amount of effective minimizing lifting operation personnel and working strength, further enhancing the assurance to on-the-spot integral construction progress, features such as its " flexible, convenient, load-carrying ability is large, detachable, multi-functional ", can be large equipment from now on and installs and provide efficient hanging device.

Detailed description of the invention
The utility model is further illustrated below by way of specific embodiment.
As shown in Figure 1 and Figure 2, a kind of hoisting appliance of large-sized rolling mills frame, it comprises frame-type bracing frame, bearing beam 2 and lift module, described frame-type bracing frame comprises column 1, connecting cross beam 4 and pull bar 3, column 1 has four and vertically arranges, connected by connecting cross beam 4 between column 1 and form frame-type bracing frame, the top level of frame-type bracing frame is provided with bearing beam 2, and bearing beam 2 two ends are connected by pull bar 3 with bottom bracing frame; Lift module comprises lift oil cylinder 8, suspender 7 and steel strand cable 9, lift oil cylinder 8 is connected with adopting steel strand cable 9 between suspender 7, as shown in Figure 3, Figure 4, described suspender 7 comprises over sling 701, connecting panel 702, rotating frame 5 and upper rotating shaft 703, lower rotary shaft 704, connecting panel 702 is located in over sling 701, its top is connected with the lower rotation of over sling 701 by upper rotating shaft 703, rotating frame 5 is positioned at the bottom of connecting panel 702, is rotationally connected between bottom its two ends and connecting panel 702 by lower rotary shaft 704; The lift oil cylinder 8 of described lift module is fixed on connecting cross beam 4 vertically, is provided with rotating support 6 between rotating frame 5 and connecting cross beam.
