[0035] When installing the piercing piece between the hole on the hull and the pipe, the installation device for watertight and fireproof piercing pieces disclosed in the second embodiment of the present invention first opens the movable semicircular clamp seat 302 from the open end of the fixed semicircular clamp seat 301, and then inserts two symmetrical piercing piece plugs into the first plug clamp ring 503 and the second plug clamp ring 505 respectively, then aligns the fixed semicircular clamp seat 301 with the pipe up and down, and then slowly lifts the lifting plate 300 upwards through the lifting mechanism 200, and when the fixed semicircular clamp seat 301 fits the lower half of the pipe, the movable semicircular clamp seat 302 with the piercing piece is fitted on the fixed semicircular clamp seat 301.

[0038] Finally, it should be noted that the mobile chassis 100 and the lifting mechanism 200 in this embodiment 2 can be directly discarded, and directly setting up a mechanism above the lifting mechanism 200 for use can also achieve the purpose of installing the piercing component between the hole on the hull and the pipeline.

[0039] A parallel moving mechanism is added to the existing device, so that the device can realize the installation of multiple pipes without moving the entire trolley. The following is the specific technical solution: Parallel movement mechanism design: Parallel moving tracks (600) are provided on both sides of the lifting carrier plate (300), and sliding blocks (601) are provided on the tracks and can move along the tracks.

[0040] The fixed semicircular clamping seat (301) and the movable semicircular clamping seat (302) are connected to the slider (601) via a connecting piece (602), so as to ensure that the clamping seats can move parallel to the track.

[0041] Drive mechanism: Electric push rods (603) are installed at both ends of the lifting carrier plate (300) to drive the slider (601) to move parallel to the track (600).

[0042] The electric push rod (603) can be controlled by a control system (604) to achieve precise position adjustment.

[0043] Control system: The control system (604) may be a PLC or a microprocessor, which is used to receive operation instructions and control the movement of the electric push rod (603).

[0044] The system may also include a sensor (605) for detecting the position of the slider (601) to ensure accurate alignment of the multiple pipes.

[0045] Operation process: The operator first installs the penetration between the hole in the hull and the pipe.

[0046] The control system (604) operates the electric push rod (603) so that the slider (601) drives the clamping seat to move to a specified position along the track (600).

[0047] Install or remove the penetration parts.

[0048] After completion, the electric push rod (603) is operated again to move the slider (601) back to its original position or to the next working position.

[0049] Security and stability: The parallel movement mechanism should be designed with a locking mechanism (606) to ensure that the slider (601) does not move accidentally during the construction process.

[0050] The material and structural design of the track (600) and the slider (601) should ensure sufficient load-bearing capacity and durability.

[0051] Through the above modifications and additional technical instructions, it is possible to install multiple pipeline penetrations at the same time without moving the trolley. These modifications will help improve installation efficiency and flexibility while ensuring the safety of the construction process.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
