Description

Technical Field

[0001] This invention relates to the field of ship hull manufacturing technology, specifically to the field of ship hull electromechanical installation, and particularly to an installation device and method for ship watertight and fireproof penetration components. Background Technology

[0002] When installing through-hull components in ship hull piping, due to the lack of suitable auxiliary tools or corresponding installation devices, workers often use simple wooden hammers to chisel the through-hull components and knock both ends of the components into the sleeve.

[0003] Traditional methods of using wooden hammers for chiseling are not only time-consuming and labor-intensive, resulting in unsightly installations; secondly, due to the high watertightness and fireproofing requirements of ships, manual hammering can easily cause deformation or damage to the penetration components; and thirdly, if problems are found after installation, the penetration components need to be removed from the hull again, a process that is extremely difficult and cumbersome. Therefore, addressing the shortcomings of existing traditional installation methods for watertightness and fireproof penetration components as mentioned in the background art, this application proposes a device for installing watertightness and fireproof penetration components on ships that effectively solves the aforementioned technical problems, enabling simple, rapid, and stable installation of penetration components and convenient subsequent removal. Summary of the Invention

[0004] The purpose of this invention is to provide a watertight and fireproof installation device for shipboard penetration components, so as to achieve simple, fast and stable installation of penetration components and convenient removal of penetration components in the future.

[0005] This invention is achieved through the following technical solution:

[0006] A shipboard watertight and fireproof penetration component installation device includes a movable chassis and a lifting mechanism. The lifting mechanism is disposed on the upper surface of the movable chassis. A lifting platform is connected to the upper end of the lifting mechanism. A fixed semi-circular clamp is disposed at one end of the upper surface of the lifting platform. A movable semi-circular clamp is rotatably connected to one end of the fixed semi-circular clamp. A pressing mechanism is disposed on the lifting platform to stably press the movable semi-circular clamp against the upper end of the fixed semi-circular clamp.

[0007] The fixed semicircular clamp and the movable semicircular clamp are equipped with a through-hole component pushing and pulling assembly. The through-hole component pushing and pulling assembly includes two sets of guide blocks arranged along the outer surfaces of the fixed semicircular clamp and the movable semicircular clamp. Each set of guide blocks has a pushing rod arranged axially through it. One end of the two pushing rods on the fixed semicircular clamp is connected to a first plug ring, and the other end is connected to a first arc plate. One end of the two pushing rods on the movable semicircular clamp is connected to a second plug ring, and the other end is connected to a second arc plate. A telescopic drive component is fixedly installed on the lifting plate, and the end of the telescopic drive component is connected to the first arc plate.

[0008] As a further provision of the above solution, the clamping mechanism includes a vertical rod fixedly connected to the lifting plate, a top plate connected to the top of the vertical rod, a notch opened on the top plate located directly above the fixed semi-circular clamp, a swing block rotatably connected in the notch, a pressure rod passing through the swing block, a pressure wheel acting on the upper surface of the movable semi-circular clamp connected to the lower end of the pressure rod, and a positioning groove matching the pressure wheel opened on the upper surface of the movable semi-circular clamp.

[0009] As a further feature of the above scheme, a column block is provided at both ends of the notch, a pin hole is provided at the center of the column block, and an arc groove is provided around the pin hole. A pin shaft matching the pin hole and a guide rod matching the arc groove are provided on both sides of the swing block.

[0010] As a further feature of the above scheme, a cylindrical cavity is provided in the swing block, a limit block is fixed on the pressure rod located in the cylindrical cavity, and a spring is connected between the limit block and the top wall of the cylindrical cavity.

[0011] As a further feature of the above scheme, a pull ring is connected to the top of the pressure rod extending from the swing block.

[0012] As a further feature of the above solution, the lower surface of the mobile chassis is provided with several casters with foot brakes, and a push handle is provided on one side of the upper end of the mobile chassis.

[0013] As a further provision of the above solution, the lifting mechanism includes a fork-type lifting frame disposed on the upper surface of the mobile chassis, the lifting plate being connected to the upper end of the fork-type lifting frame, and a manual device for extending and retracting the fork-type lifting frame being disposed on the upper surface of the mobile chassis.

[0014] As a further provision of the above solution, the manual device includes a movable block connected to the lower end of the fork-type lifting frame. The movable block has a threaded hole. The upper surface of the movable housing has a straight groove that interacts with the movable block. A lead screw is inserted through the threaded hole of the movable block. Both ends of the lead screw are rotatably connected to bearing seats fixed on the upper surface of the movable housing. A handwheel is connected to one end of the lead screw that extends out of the movable housing.

[0015] As a further feature of the above solution, both ends of the push rod on the movable semicircular clamp are connected to arc-shaped insert rods, and both ends of the push rod on the fixed semicircular clamp are provided with insertion holes that match the arc-shaped insert rods.

[0016] The present invention also discloses a method for installing the above-mentioned installation device on a ship's watertight and fireproof penetration components, comprising the following steps:

[0017] 1) Insert the through-hole component between the hole and the pipe on the hull, then open the movable semi-circular clamp from the top of the fixed semi-circular clamp, and then insert the two symmetrical through-hole plugs into the first plug retaining ring and the second plug retaining ring respectively.

[0018] 2) Align the fixed semicircular clamp with the pipe vertically, and lift the lifting plate upward using the lifting mechanism until the fixed semicircular clamp is attached to the lower half of the pipe. Then, place the movable semicircular clamp on the fixed semicircular clamp and press it in place using the clamping mechanism.

[0019] 3) Activate the telescopic drive to push the first and second plug circumferential rings toward the circumferential seam between the hull hole and the pipe until the plug part of the through-hole is fully inserted into the circumferential seam;

[0020] 4) Remove the clamping action of the clamping mechanism on the movable semi-circular clamp, open the movable semi-circular clamp from the fixed semi-circular clamp, and then control the lifting mechanism to move downward so that the fixed semi-circular clamp is separated from the pipe.

[0021] 5) When it is necessary to remove the through-hole component from the hull, simply insert the first and second plug clasps into the plug of the through-hole component, and then reverse the telescopic drive to retract it, thus removing it from the annular gap between the hole and the pipe.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. The watertight and fireproof through-hole component installation device disclosed in this invention first uses the movable and fixed semi-circular clamps to tightly fit and fix the through-hole component to the pipe during installation. At the same time, the through-hole component plug and plug retaining ring are fixed. Then, under the pushing action of the telescopic drive, the through-hole component can be forcibly squeezed into the annular gap between the hole and the pipe on the hull. The entire installation device can realize the electric and rapid installation of the watertight and fireproof through-hole component. Moreover, when it is necessary to pull out the through-hole component, it is only necessary to reverse the telescopic drive. It is not only fast and convenient to install the through-hole component, but also has multiple functions. During the installation process, it can ensure that the circumferential force is uniform, thus ensuring the sealing effect after installation.

[0024] 2. The present invention further includes a mobile housing and a lifting mechanism. The mobile housing provides stable support during the installation and operation of the entire device, and the device is easy to move and fix, making it more convenient to use. The lifting mechanism allows for quick adjustment of the installation height of the through-cabin parts, meeting the needs of electric installation of through-cabin parts in various locations, thus increasing its applicability.

[0059] Reference Appendix Figure 5 and attached Figure 6 A through-cabin component pushing and pulling assembly 500 is provided on the fixed semicircular clamp 301 and the movable semicircular clamp 302. Specifically, the through-cabin component pushing and pulling assembly 500 includes two sets of guide blocks 501 arranged along the outer surfaces of the fixed semicircular clamp 301 and the movable semicircular clamp 302. A pushing rod 502 arranged axially is inserted through each set of guide blocks 501.

[0060] In this embodiment 2, the shipboard watertight and fireproof penetration device for installing penetration components between the hull hole and the pipe involves first opening the movable semicircular clamp 302 from the open end of the fixed semicircular clamp 301, then inserting two symmetrical penetration component plugs into the first plug retaining ring 503 and the second plug retaining ring 505 respectively. Next, the fixed semicircular clamp 301 is aligned vertically with the pipe, and the lifting platform 300 is slowly raised upwards via the lifting mechanism 200. When the fixed semicircular clamp 301 is against the lower half of the pipe, the movable semicircular clamp 302, holding the penetration component, is closed onto the fixed semicircular clamp 301. Subsequently, the horizontally positioned swing block 404 is rotated to vertical, and then the movable semicircular clamp 302 is pressed tightly onto the fixed semicircular clamp 301 by the pressure rod 405, pressure roller 406, and spring 409, ensuring a tight fit against the outer wall of the pipe.

[0061] Subsequently, the telescopic drive 507 is activated to extend its piston rod. Then, under the action of the push rod 502 and the arc-shaped insertion rod 508, the first plug retainer 503 and the second plug retainer 505 are pushed into the annular gap between the hull hole and the pipe until the plug part of the through-hole component is fully inserted. Finally, the clamping mechanism 400 is released from its clamping effect on the movable semi-circular clamp 302, and the movable semi-circular clamp 302 is opened from the fixed semi-circular clamp 301. Then, the lifting mechanism 200 is controlled to move downward, so that the fixed semi-circular clamp 301 is separated from the pipe.

[0062] In addition, when it is necessary to remove the through-hole component from the hull, the first plug retaining ring 503 and the second plug retaining ring 505 are directly inserted into the plug of the through-hole component, and then the telescopic drive component 507 is retracted in the opposite direction to pull it out from the annular gap between the hole and the pipe.

[0063] Finally, it should be noted that the mobile housing 100 and the lifting mechanism 200 in this embodiment 2 can be directly discarded. The mechanism above the lifting mechanism 200 can also be used to achieve the function of inserting the through-cabin parts into the holes and pipes on the hull.

[0064] By adding a parallel movement mechanism to the existing device, the installation of multiple pipes through the compartment can be achieved without moving the entire trolley. The specific technical solution is as follows:

[0065] Design of parallel movement mechanism:

[0066] Parallel moving rails (600) are added to both sides of the lifting plate (300), and sliders (601) that can move along the rails are provided on the rails.

[0067] The fixed semicircular clamp (301) and the movable semicircular clamp (302) are connected to the slider (601) via the connector (602) to ensure that the clamp can move parallel to the track.

[0068] Driving mechanism:

[0069] Electric push rods (603) are installed at both ends of the lifting plate (300) to drive the slider (601) to move parallel to the track (600).

[0070] The electric actuator (603) can be controlled by the control system (604) to achieve precise position adjustment.

[0071] Control system:

[0072] The control system (604) may be a PLC or a microprocessor, used to receive operating instructions and control the movement of the electric actuator (603).

[0073] The system may also include a sensor (605) for detecting the position of the slider (601) to ensure precise alignment of the multiple pipes.

[0074] Operating procedures:

[0075] The operators first insert the hatch-through component between the hole and the pipe on the hull.

[0076] The electric push rod (603) is operated by the control system (604) so ​​that the slider (601) drives the clamp to move along the track (600) to the designated position.

[0077] To carry out the installation or removal of the compartment components.

[0078] After completion, operate the electric push rod (603) again to move the slider (601) back to its original position or to the next working position.

[0079] Safety and stability:

[0080] The parallel movement mechanism should be designed with a locking mechanism (606) to ensure that the slider (601) does not move unexpectedly during construction.

[0081] The materials and structural design of the track (600) and slider (601) should ensure sufficient load-bearing capacity and durability.

[0082] The aforementioned modifications and additions to the technical specifications enable the simultaneous installation of multiple pipework components without moving the trolley. These modifications will improve installation efficiency and flexibility while ensuring safety during the construction process.

[0083] The above are merely 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 within the protection scope of the present invention.
