Description

Technical Field

[0001] The present invention relates to the technical field of dredger engineering, and particularly to a floating-assembly bridge locking trunnion seat. Background Art

[0002] In the prior art, the 7800kw cutter power self-propelled trailing suction hopper dredger is currently the largest self-propelled trailing suction hopper dredger independently designed and under construction in Asia in China. This ship has the characteristics of shallow draft, large dredging depth, self-deployment, high power, high intelligence, etc. To achieve dredging operations, this ship is equipped with an extra-heavy bridge with a total weight of 1900t. The locking tie rods used to fix the bridge during the deployment of conventional trailing suction hopper dredgers are not sufficient to support its weight. Therefore, this ship is configured with locking trunnions for bridge fixation. In order to ensure the effectiveness of the trunnion seats, the trunnion seats on the bridge and the hull need to be bored correspondingly. With such a setting, for an extra-heavy bridge close to 1900t, the construction process is very complex, and the required processes and special tooling are also relatively many. The on-site installation work is difficult, and the construction period of the bridge is relatively long. At the same time, after the ship is put into operation and construction, if the bridge is deformed due to long-term construction, its locking trunnions cannot be adjusted according to the positioning after deformation, and the maintenance cost is relatively high. Summary of the Invention

[0003] The purpose of the present invention is to provide a floating-assembly bridge locking trunnion seat, which reduces the construction difficulty of the trunnion seat, realizes the adjustability of the height and horizontal position of the base and floating assembly, reduces the on-site installation work, and realizes the pre-installation of relevant strengthening structures.

[0004] To achieve the above purpose, the present invention proposes a floating-assembly bridge locking trunnion seat, which includes a bridge support base, a trunnion pin installed in the bridge support base, a movable pressing block arranged above the trunnion pin, and a pin support block arranged below the trunnion pin. A base is provided below the pin support block, and a plurality of support gussets are arranged below the base. The pin support block is movably assembled on the upper surface of the base, the lower surface of the base is in contact with the support gussets, and the lower surface of the base is an inclined surface.

[0005] Further as an improvement of the technical solution of the present invention, a long strip-shaped limiting plate is provided above one side of the base in contact with the support gussets.

[0006] Further as an improvement of the technical solution of the present invention, one surface of the pin support block is provided with an ear plate, the ear plate is in mutual contact with the support gussets, and the support gussets and the ear plate are connected by bolts.

[0007] Further as an improvement of the technical solution of the present invention, the length of the contact edge of the support gussets and the base is greater than the length of the lower surface of the base.

[0008] As a further improvement of the technical solution of the present invention, one side of the supporting gusset plate in contact with the base is a wedge-shaped edge. The upper part of the wedge-shaped edge is perpendicular to the horizontal plane, the lower part of the wedge-shaped edge forms an inclined angle with the horizontal plane, and the lower part of the wedge-shaped edge is in contact with the upper surface of the base.

[0009] As a further improvement of the technical solution of the present invention, there are several wedge-shaped feet under the base, and the lower surfaces of the wedge-shaped feet are the contact surfaces with the supporting gusset plate.

[0010] As a further improvement of the technical solution of the present invention, the base and the supporting gusset plate are fixed by welding.

[0011] The beneficial effects of the present invention are as follows: The pin support block of the bridge locking trunnion seat of the present invention is movably connected to the base, so the pin support block can be translated left and right on the base according to the actual position of the trunnion pin, making the pin support block and the trunnion pin better cooperate. Moreover, the lower surface of the base is in close contact with each supporting gusset plate, and the lower surface of the base is an inclined plane, so there is a certain relative distance between the base and the supporting gusset plate. By changing the relative distance between the two, the height of the base can be adjusted accordingly, realizing the floating assembly of the bridge locking trunnion seat, reducing the complicated on-site installation work, and lowering the construction difficulty. At the same time, this structural setting reduces the setting of the matching boring holes of the two side trunnion seats, thereby shortening the construction period of the bridge.

[0017] As Figures 1 to 4, the present invention relates to a floating-assembly bridge locking trunnion seat, which includes a bridge support base 6, a trunnion pin 5 installed in the bridge support base 6, a movable pressing block 1 arranged above the trunnion pin 5, and a pin support block 2 arranged below the trunnion pin 5. There is a base 3 below the pin support block 2, and several support gussets 4 are arranged below the base 3. The pin support block 2 is movably assembled on the upper surface of the base 3. The lower surface of the base 3 is in contact with the support gussets 4, and the lower surface of the base 3 is an inclined plane.

[0018] The pin support block 2 is movably assembled on the base 3. During construction, according to the position of the trunnion pin 5, the pin support block 2 moves left and right on the base 3 to a suitable position, so that the pin support block 2 and the trunnion pin 5 can cooperate better with each other. During this process, there is no need to move the entire bridge locking trunnion seat, saving manpower. Also, the lower surface of the base 3 is in contact with the support gussets 4, and the lower surface of the base 3 is an inclined plane. Therefore, during assembly, there is a certain relative distance between the longitudinal surface of the base 3 and the support gussets 4. By adjusting the size of the relative distance between the two, the base 3 slides and adjusts on the support gussets 4, and the height adjustment of the base 3 can be realized. Thus, the up, down, left, and right floating assembly of the bridge locking trunnion seat is achieved, reducing the boring work of the two-sided trunnion seats and effectively shortening the construction period of the bridge. At the same time, if the bridge deforms due to long-term construction, the floating-assembly bridge locking trunnion seat can adjust the positioning according to the deformation, greatly reducing the maintenance cost.

[0019] As a preferred embodiment of the present invention, a long strip-shaped limiting plate 31 is arranged above one side of the base 3 in contact with the support gussets 4. The setting of this long strip-shaped limiting plate 31 limits that the pin support block 2 can only move left and right on the base 3, ensuring that the movement of the pin support block 2 does not deviate from the direction.

[0020] As a preferred embodiment of the present invention, one side of the pin support block 2 is provided with an ear plate, and the ear plate is in mutual contact with the support gussets 4. The support gussets 4 and the ear plate are connected by bolts. Using bolt connection makes the pin support block 2 and the support gussets 4 form a whole, ensuring the stability of the bridge locking trunnion seat during construction.

[0021] As a preferred embodiment of the present invention, the length of the contact edge between the support gussets 4 and the base 3 is greater than the length of the lower surface of the base 3. With such a setting, the difference between the length of the contact edge on the support gussets 4 and the length of the lower surface of the base 3, that is, the distance that the base 3 can move on the support gussets 4, facilitates the construction personnel to determine the height adjustment range of the base 3.

[0022] As a preferred embodiment of the present invention, one side of the support gussets 4 in contact with the base 3 is a wedge-shaped edge. The upper part of the wedge-shaped edge is perpendicular to the horizontal plane, the lower part of the wedge-shaped edge forms an inclined angle with the horizontal plane, and the lower part of the wedge-shaped edge is in contact with the upper surface of the base 3.

[0023] As a preferred embodiment of the present invention, there are several wedge-shaped feet under the base 3, and the lower surface of each wedge-shaped foot is the contact surface with the support gusset 4. The setting of the feet saves the manufacturing material of the base 3 and at the same time ensures the stability of the base 3.

[0024] As a preferred embodiment of the present invention, the base 3 and the support gusset 4 are fixed by welding. After determining the height of the base 3 during the assembly process, the base 3 and the support gusset 4 are fixed together by welding, making the two into a whole, and at the same time ensuring that the determined support height does not change.

[0025] Of course, the design and creation of the present invention are not limited to the above embodiments, and the combination of different features of the above embodiments can also achieve good effects. Those skilled in the art can also make equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
