Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

First embodiment, as shown in fig. 1 and fig. 2, a worker puts a first bracket 1 on a base plate which is arranged in advance, then the worker finds that a leveling plate 2 is not horizontal by observing a leveling mechanism, then the worker rotates a first screw rod which drives a first adjusting block 6 which is arranged in a rotating way and is vertically and slidably arranged on the first bracket 1 to move, the first adjusting block 6 moves, a second adjusting block 8 which is arranged at the other end of the first adjusting arm 7 in a rotating way and is slidably arranged on the leveling plate 2 is driven by the first adjusting arm 7 to move, the second adjusting block 8 moves and drives the leveling plate 2 to move, the worker finds that the horizontal direction of the leveling plate 2 is horizontal by observing a leveling structure, then the worker stops driving the first screw rod, the first adjusting block 6 is arranged to be not parallel to the rotating shaft direction of the first adjusting arm 7 which is matched with the first adjusting block 8 and the rotating shaft direction of the first adjusting arm 7 which is matched with the second adjusting block 8, the non-parallelism can be 70 degrees, 80 degrees, 90 degrees, etc.;

then the staff rotates the third screw, the third screw rotates and drives the fifth adjusting block 12 which is installed with the third screw in a rotating mode and vertically and slidably installed on the first support 1 to move, the fifth adjusting block 12 moves and is driven by the third adjusting arm 13 to rotate and installed at the other end of the third adjusting arm 13 and slidably installed on the leveling plate 2 to move, the sixth adjusting block 14 moves and drives the leveling plate 2 to move, the staff finds that the longitudinal direction of the leveling plate 2 is horizontal by observing the leveling structure, then the staff stops driving the second screw, the first adjusting block 6 is arranged around the rotating shaft direction of the first adjusting arm 7 matched with the first adjusting block 6, the second adjusting block 8 is arranged not parallel to the rotating shaft direction of the first adjusting arm 7 matched with the second adjusting block 8, the non-parallel can be 70 degrees, 80 degrees, 90 degrees and the like

After the workers observe the leveling mechanism to find that the horizontal and longitudinal directions of the leveling plate 2 are horizontal, the workers simultaneously drive the first screw rods 3, the second screw rods and the third screw rods 5 to enable the leveling plate 2 to horizontally ascend to a specified position, and then the workers can manufacture the segment beams after the side plates and the end plates are placed;

the worker can also adjust the horizontal direction of the longitudinal direction at first, the worker rotates the second screw rod, the second screw rod drives the third adjusting block 9 which is installed with the second screw rod in a rotating mode and vertically and slidably installed on the first support 1 to move in a rotating mode, the third adjusting block 9 moves, the fourth adjusting block 11 which is installed at the other end of the second adjusting arm 10 in a rotating mode and slidably installed on the adjusting plate 2 is driven by the second adjusting arm 10 to move in a rotating mode, the fourth adjusting block 11 moves and drives the adjusting plate 2 to move in a moving mode, the worker finds that the longitudinal direction of the adjusting plate 2 is horizontal through observing the leveling structure, then the worker stops driving the second screw rod, the first adjusting block 6 is arranged around the rotating shaft direction of the first adjusting arm 7 matched with the first adjusting block 6 and the rotating shaft direction of the second adjusting block 8 matched with the second adjusting arm 7, and the unparallel can be 70 degrees, 80 degrees, 90 degrees and the like; when the staff adjusts the longitudinal direction level, the second screw rod 4 or the third screw rod 5 can be rotated to enable the longitudinal direction of the leveling plate 2 to be horizontal, then the horizontal direction level is adjusted, and the staff rotates the first screw rod 3 to enable the horizontal direction of the leveling plate 2 to be horizontal;

the reason why the rotation direction of the adjusting block around the adjusting arm matched with the adjusting block is not parallel to the rotation shaft direction of the adjusting block around which the other end of the adjusting arm rotates is that the leveling plate 2 is fixed when a worker does not drive any screw rod of the first screw rod 3, the second screw rod 4 and the third screw rod 5.

In the second embodiment, on the basis of the first embodiment, when the leveling plate 2 is horizontal in the transverse direction, the third spring and the fourth spring are in the original length state, the third pointer 18 and the fourth pointer 19 are located at the 0 scale of the corresponding scale, when the leveling plate 2 is horizontal in the longitudinal direction, the first spring and the second spring are in the original length state, the first pointer 15 and the second pointer 16 are located at the corresponding 0 scale, and the first leveling ball 17 is in contact with the first observation block and the second observation block;

when the leveling plate 2 is not horizontal in the transverse direction, the second leveling ball 20 rolls under the action of self gravity, so that the second leveling ball 20 rolls, the third spring or the fourth spring is compressed, the third pointer 18 or the fourth pointer 19 is not positioned at the 0 scale of the corresponding scale, and the second leveling ball 20 is in contact with the third observation block and the fourth observation block;

the worker drives the first screw rod 3 to enable the leveling plate 2 to move to be in a horizontal state, the second leveling ball 20 returns to the position where the leveling plate 2 is located when the leveling plate 2 is in the horizontal state under the action of the third spring or the fourth spring, and the third pointer 18 and the fourth pointer 19 are arranged to enable the worker to better observe whether the leveling plate 2 is in the horizontal state or not in the horizontal direction;
