The length of the adjusting strut 48 is changed by the threaded rod segment; a main pulley 481 is installed at the end of the main strut 48, and the end of the auxiliary strut 47 is rotatably connected to the position near the top of the main strut 48, and is connected with the main strut 48. The auxiliary strut 47 is provided with a matching latch rod structure 474. The secondary brace 47 can be turned to the inner side of the main brace 48 and folded up. After unfolding, the auxiliary brace 47 can be fixed by the latch rod structure 474; A secondary guide pulley 473 is installed at the top, and the hoisting device 45 is connected with a double-stranded cable 451. The double-stranded cable 451 bypasses the primary pulley 481 and the secondary guide pulley 473 respectively and is connected to the boom 452. The boom 452 is used for connecting Covered bridge unit 3.

During the construction of the covered bridge, firstly, for the covered bridge unit 3 on the ground floor, the covered bridge unit 3 is lifted to a predetermined height by the device body 4, and then the covered bridge unit 3 on the ground floor is welded, assembled and fixed, so that it is assembled to the shaft. Between the steel structure 2 and the outer wall masonry 1, the installation of the ground floor bridge unit 3 is completed; then, use the elevator system to transfer the device body 4 to the ground floor bridge unit 3, and process and install it on the steel frame on the bottom surface of the ground floor bridge unit 3 The hole is connected and fixed with the prefabricated hole on the bottom support 41 of the device body 4 through the connector, and the device body 4 is fixed to the bottom covered bridge unit 3, and then the support rod assembly on the top platform 46 is unfolded, that is, the main support rod 48 and After the adjusting brace 49 is unfolded, connect the adjusting brace 49 to the main brace 48, then unfold and fix the auxiliary brace 47, and wind the double-stranded cable 451 on the hoisting device 45 over the main pulley 481 and the auxiliary guide pulley 473 respectively. , connect the suspension rod 452 to the covered bridge unit 3 to be hoisted, and hoist the covered bridge unit 3 to a height not lower than the top of the bottom covered bridge unit through the hoisting device 45 to stop;

Change the length of the adjusting strut 49 to make the main strut 48 rotate, the secondary strut 47 is lowered in height and moves to one side at the same time, when the length of the strut 49 is adjusted to the shortest, the hoisting gallery bridge unit 3 moves down and moves to the right for a certain distance at the same time, Complete the initial adjustment, as shown in Figure 4, then drive the top platform 46 to move as a whole through the driving mechanism 44, and drive the covered bridge unit 3 to continue to move to one side, so that most of the covered bridge unit 3 is located above the lower covered bridge unit 3, complete For the second adjustment, in order to avoid the interference between the special-shaped pipe on the bottom side of the bridge unit 3 and the device body 4, the steel pipe at this place can be not welded in advance, and the steel pipe at this place can be welded after it is hoisted in place;

The above-mentioned adjustment methods can also be reversed, that is, the position of the top platform 46 can be translated as a whole first, and then the support rod can be adjusted downward and displaced.

As shown in FIGS. 5 and 6 , a sliding groove 471 is provided on the auxiliary strut 47 , the auxiliary guide wheel 473 is slidably connected in the sliding groove 471 , and a locking bolt mechanism 472 for fixing its position is provided on the auxiliary guide wheel 473 , During the hoisting process, the secondary guide wheel 473 is locked and fixed by the locking bolt mechanism 472. After the above-mentioned adjustment process is completed, the locking bolt is loosened, and the hoisting device 45 is started. At this time, the double-strand cable 451 will pull the secondary guide wheel. 473 move slowly, and at the same time move the pulling bridge unit 3 as a whole until it basically corresponds to the position of the lower covered bridge, complete the three-position adjustment, and then lower the covered bridge to the lower covered bridge.
