Description

Technical Field

[0001] This utility model relates to the technical field of ship liquid cargo tank cleaning equipment, and in particular to a fixed bracket for a ship multi-nozzle tank cleaning machine. Background Technology

[0002] The cargo hold bulkheads of the product oil tanker project are transverse trough-shaped bulkheads. Due to the much larger blind spots compared to ordinary longitudinal trough-shaped bulkheads, a multi-nozzle tank cleaning machine is required. Because the cargo hold is very high, the piping of the multi-nozzle tank cleaning machine is quite long. Currently, clamp-type supports are used to secure the piping. However, since the height of liquid cargo tanks often exceeds 15 meters, the support installation location is difficult to reach. Traditional solutions require additional scaffolding. The clamps of the supports are located in the middle of the cargo hold, requiring bolts to be tightened at a high altitude inside the hold. This necessitates the erection of temporary platforms for operators, increasing the empty weight of the hull and safety risks. Furthermore, the tank cleaning machine operates at a vibration frequency of 5-10Hz, and insecure fixing can easily lead to pipe breakage or nozzle misalignment.

[0003] Therefore, this utility model proposes a fixing bracket for a marine multi-nozzle tank cleaning machine, which is suitable for the rapid installation and anti-loosening fixing of multi-nozzle tank cleaning machines in high-altitude operation environments, and solves the problems of installation difficulties and safety hazards caused by the reliance on bolt tightening in traditional brackets. Summary of the Invention

[0004] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a fixed bracket for a marine multi-nozzle tank cleaning machine, which enables insertion installation, reduces high-altitude operation time, and eliminates the need for scaffolding construction.

[0005] The purpose of this utility model is achieved as follows: A mounting bracket for a marine multi-nozzle tank cleaning machine is provided for fixing the multi-nozzle tank cleaning machine. The multi-nozzle tank cleaning machine includes a main tank cleaning machine pipeline. At least one support bracket assembly is provided on the main tank cleaning machine pipeline. The support bracket assembly includes a support clamp, a bushing, and a pipe clamp arranged from the inside to the outside. The support clamp includes an inner ring, connecting ribs, and an outer ring. The inner ring and the outer ring are arranged in an inner and outer arrangement. At least two connecting ribs are arranged symmetrically on the left and right sides between the inner ring and the outer ring. The inner ring and the outer ring are connected by the connecting ribs. The inner ring is fitted onto the main pipeline of the washing machine. The bushing is annular and fits snugly against the inner wall of the pipe clamp. The bushing is made of Teflon. The pipe clamp includes a circular outer shell and a connector. The connector is disposed outside the circular outer shell and is perpendicularly connected to the circular outer shell. A bushing is pressed into the inner wall of the circular outer shell, and the inner diameter of the bushing is interference-fitted with the outer diameter of the support clamp.

[0006] Furthermore, the top of the main pipeline of the tank washing machine is provided with an inlet chamber, the side of the inlet chamber is provided with a water inlet, and the main pipeline of the tank washing machine is provided with multiple nozzles and flanges.

[0007] Furthermore, a control unit and a protective cover are provided above the inlet chamber, and the control unit and the protective cover are fixed above the top surface of the main pipeline of the washing machine.

[0008] Furthermore, a deck flange is provided below the inlet chamber, and the deck flange is fitted onto the main pipeline of the tank washing machine.

[0009] Furthermore, the inner collar is connected to the main pipeline of the tank cleaning machine by bolts and nuts in an adjustable manner. Before the multi-nozzle tank cleaning machine is used, the inner collar is attached to the main pipeline, eliminating the need for on-site installation.

[0010] Furthermore, the inner ring is wider at the top and bottom than the outer ring, so the top and bottom edges of the inner ring are exposed above the outer ring.

[0011] Furthermore, the interference fit between the bushing and the support clamp is 0.5-1mm.

[0012] Furthermore, the inner wall of the annular outer shell of the pipe clamp is provided with an anti-rotation protrusion key, and the outer wall of the bushing is provided with a corresponding keyway.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This utility model provides a mounting bracket for a marine multi-nozzle tank cleaning machine, which has the following specific advantages: (1) Zero risk in high-altitude operations: The main pipeline of the tank washing machine is pre-installed with support clamps, which can be inserted vertically into the bracket during installation, completely avoiding personnel entering the tank for high-altitude work and preventing fall accidents.

[0014] (2) Improved installation / removal efficiency: The installation / disassembly time is greatly reduced compared to existing solutions. Crew members do not need to erect scaffolding in the cargo hold when disassembling and maintaining the machine. Since it is difficult to erect scaffolding after the ship leaves the factory, this utility model is more conducive to the disassembly of the tank cleaning machine.

[0015] (3) Vibration resistance and anti-loosening: The Teflon bushing and support clamp are interference-fitted to effectively absorb the vibration energy of ships at 5-10Hz.

[0016] (4) Low maintenance costs: Teflon material is resistant to acid and alkali corrosion, has a lifespan of more than 8 years, and the support clamps and pipe clamps can be reused, greatly reducing maintenance costs. Attached Figure Description
