Description

Technical Field

[0001] This invention relates to a detachable boom-type fluorescent lamp fixing device, which belongs to the field of ship design technology. Background Technology

[0002] With the continuous development of the shipping industry, more and more new equipment is being used in the shipbuilding sector, and some of this equipment requires regular maintenance and repair. During maintenance, the lifting lugs on top of the equipment lift it, but the fluorescent lights on top sometimes obstruct the lifting process. Traditional mounting methods rely on non-removable bases, making maintenance inconvenient. This invention modifies this by using a detachable fluorescent light base, efficiently solving this problem.

[0003] Currently, the bases of commonly used fluorescent lamp hanging rods are not removable. Lamp fixtures that obstruct the lifting of equipment must be cut off before welding, causing secondary burns and increasing labor and material costs. Furthermore, in some areas where hot work is restricted, disassembly and installation are quite difficult. Summary of the Invention

[0004] To address the problems existing in the prior art, this invention provides a detachable rod-type fluorescent lamp fixing device. The end fixing component and the lamp mounting component adopt a detachable flange structure. The use of a detachable flange as a connection solves the difficulty of non-disassembly. At the same time, no hot work is required during installation, reducing manpower and material costs, and it does not affect the disassembly and installation of hazardous areas.

[0005] The technical solution adopted in this invention is: a detachable rod-type fluorescent lamp fixing device, which includes an end fixing component, a lamp mounting component, and a lamp hanging component connected in sequence; In the end fastener, one end of the fastener body is a welding end, used for welding and fixing to the top wall of the cabin, and the other end is a fastener flange; In the lamp mounting component, one end of the main body of the mounting component is a mounting flange, which is detachably fixed to the fixing flange; the other end of the main body of the mounting component is a flat tube connector; the flat tube connector is welded and fixed to the lamp hanging component; the two ends of the lamp hanging component are provided with spring-type hanging parts for suspending fluorescent lamps.

[0006] Furthermore, the mounting body is also provided with shock-absorbing connectors.

[0007] Furthermore, the shock-absorbing connector is provided with bolt holes, and the shock-absorbing connector is bolted to one end of the shock-absorbing connecting arm, while the other end is set on the side wall of the cabin.

[0008] Furthermore, both the main body of the fixing component and the main body of the mounting component are made of thick-walled tubes, and their lengths are adjustable according to the available space; the main body of the lamp hanging component is made of long oval tubes.

[0009] Compared with the prior art, the present invention has the following advantages: the device adopts a flange docking detachable connection method, which can realize the quick separation of the upper fixed structure and the lower suspended structure. The lamps can be disassembled, replaced and repaired without damaging the hull and the mounting base. The operation is simple and efficient, which greatly reduces the daily operation and maintenance cost and construction difficulty of the ship.

[0010] This device uses thick-walled tubes as the main load-bearing structure, which has high structural strength, good rigidity, and strong resistance to deformation, making it able to adapt to the ship's turbulence, swaying, and complex load environment. At the same time, the length of the end fixing parts and lamp mounting parts can be flexibly customized according to the cabin height and on-site installation space, which can adapt to the fluorescent lamp arrangement requirements of different cabins and different installation heights. The versatility and on-site adaptability are significantly improved, solving the problems of traditional fixed hanging rods with single size and poor adaptability.

[0011] This device utilizes spring-type suspension components at both ends of the lamp's suspension assembly to achieve flexible lamp suspension through the inherent elasticity of the spring structure. This effectively buffers low-frequency vibrations generated during normal ship navigation, reducing the direct transmission of vibrations to the fluorescent lamp body and preventing malfunctions such as loose lamp tubes, lamp deformation, and cracked lifting lugs. Simultaneously, external shock-absorbing connectors are added, which, in conjunction with external shock-absorbing structures in high-vibration areas such as the engine room, form auxiliary shock-absorbing constraints, creating a multi-stage shock-absorbing structure that combines primary and secondary components. This further weakens hull vibrations and impact loads, significantly improving the installation stability and lifespan of the fluorescent lamp.

[0012] Furthermore, this device features a simple structure and ingenious design, achieving its design objectives through the combination of several simple components. The overall structure is concise and highly modular, facilitating installation and construction. It is structurally safe and reliable, capable of meeting the operating conditions of both ordinary and high-vibration chambers, making it widely applicable and demonstrating significant comprehensive effectiveness and promotional value.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] This embodiment discloses a detachable rod-type fluorescent lamp fixing device, which is suitable for the suspension and installation of fluorescent lamps in various cabins of ships. It can be adapted to the use scenarios of conventional cabins, passageways and high-vibration engine rooms. The overall structure includes an end fixing part 1, a lamp mounting part 2, a shock-absorbing connecting part 3, and a lamp hanging part 4. The components are assembled and matched in sequence to achieve stable suspension and shock absorption protection of the fluorescent lamp 5.

[0022] The end fastener 1 is equipped with a fastener body 1a, which is made of thick-walled metal tubing and arranged vertically. The upper end of the fastener body 1a is a welded end 1b, which is fully welded to the top wall 6 of the hull, achieving top positioning and installation of the entire device. The lower end of the fastener body 1a is integrally fitted with a fastener flange 1c, which has evenly distributed bolt holes for connecting to the lower structure. The overall length of the fastener body 1a can be customized and adjusted according to the cabin height and lighting installation height requirements to adapt to different installation spaces.

[0023] In some specific embodiments, the end fixing member 1 consists of a thick-walled tube and a fixing flange. The length of the thick-walled tube can be customized according to actual conditions to meet the installation needs of fluorescent lamps in different locations.

[0024] The lighting fixture mounting component 2 is equipped with a mounting body 2a, which is also made of thick-walled metal tubing, and its length can be flexibly adjusted according to the on-site installation conditions. A mounting flange 2b is fixedly installed at the upper end of the mounting body 2a, and the mounting flange 2b corresponds and matches with the fixing flange 1c. A detachable, fitted fixing is achieved by tightening bolts, enabling quick assembly and separation of the end fixing component 1 and the lighting fixture mounting component 2. A flattened tube connecting part 2c is provided at the lower end of the mounting body 2a, and the flat tube connecting part 2c has a flat welding base surface.

[0025] The top surface of the flat tube connector 2c is welded and fixed to the middle position of the lamp suspension component 4. The main body of the lamp suspension component 4 adopts a circular long tube structure and is arranged horizontally. Spring-type suspension parts 4a are symmetrically arranged at the left and right ends of the lamp suspension component 4. The spring-type suspension parts 4a have elastic buffering performance and can be directly hooked onto the mounting lugs at both ends of the fluorescent lamp 5 to realize the suspension and fixation of the fluorescent lamp 5. At the same time, it can slightly buffer the normal vibration generated by the operation of the ship and reduce the vibration loss of the fluorescent lamp body.

[0026] In some specific embodiments, the luminaire mounting component 2 consists of a flange and a thick-walled tube. One end of the thick-walled tube is welded to a flange, and the other end is flattened and welded to a long oval tube with a diameter of 13 mm. The luminaire suspension component 4 consists of a long oval tube with a diameter of 13 mm and two spring-type oval tubes with a diameter of 8 mm. The long oval tube with a diameter of 13 mm has two spring-type oval tubes with a diameter of 8 mm welded to both ends. The spring-type oval tubes are used to suspend the fluorescent lamp. This luminaire mounting component is connected to the end fixing component via a flange.

[0027] A vibration damping connector 3 is fixedly welded to the outer side of the middle part of the main body 2a of the mounting component. The vibration damping connector 3 is made of flat iron plate, with a through bolt hole 3b in the center of the plate surface. The vibration damping connector 3 is detachably bolted to one end of the vibration damping connecting arm 3a through the bolt hole 3b, and the other end of the vibration damping connecting arm 3a is fixedly installed on the side wall 7 of the hull compartment. Under high vibration conditions such as in the engine room and pump room, the vibration damping connecting arm 3a forms a lateral tension vibration damping structure, which, together with the end spring-type suspension part 4a, forms a double vibration damping system, significantly reducing the transmission of hull vibration to the fluorescent lamp 5 and improving the installation stability and service life of the lamp.

[0028] In some specific embodiments, the vibration damping connector 3 is a flat iron with a bolt hole. It is connected to the lamp mounting component 2 by welding. This is used when the installation environment experiences significant vibration.

[0029] The device adopts a split and detachable structure, with modular assembly of each component. The thick-walled tube main structure has high strength and strong resistance to deformation. The spring-type suspension structure takes into account both suspension fixation and foundation vibration reduction. External vibration damping connectors can be selected and used as needed. It is suitable for installation in cabins with different vibration levels on ships, and has extremely high versatility and practicality.

[0030] The installation method of this device includes the following steps: S11. Based on the actual floor height of the ship's cabin and the installation elevation of the fluorescent lamps, determine the processing length of the end fastener 1 and the lamp mounting component 2, and complete the prefabrication and anti-corrosion treatment of each component.

[0033] S14. Align the middle part of the lamp hanging part 4 with the flat tube connection part 2c at the bottom of the lamp mounting part 2 using full welding to ensure that the connection position is flat and firm.

[0034] S15. Under normal operating conditions, the mounting lugs at both ends of the fluorescent lamp 5 are directly inserted into the spring-type suspension parts 4a at both ends of the lamp suspension component 4 to complete the fluorescent lamp suspension installation.

[0035] S16. Under high vibration conditions, install the shock-absorbing connecting arm 3a at the bolt hole 3b of the shock-absorbing connecting part 3, fix the other end of the shock-absorbing connecting arm 3a to the preset installation point on the side wall 7 of the cabin, fine-tune the tightness of the structure to ensure that the shock-absorbing structure is subjected to uniform force, without pulling or loosening, and complete the overall installation operation.

[0036] The method for disassembling the device includes the following steps: S21. Before disassembly, disconnect the power supply to the fluorescent lamp and confirm that the circuit is safe to disconnect before proceeding with the disassembly operation.

[0037] S22. Under high vibration installation conditions, first remove the connecting bolts between the shock-absorbing connecting arm 3a and the shock-absorbing connecting piece 3, separate the shock-absorbing connecting arm 3a, then remove the fixing structure between the shock-absorbing connecting arm 3a and the cabin side wall 7, and remove the shock-absorbing assembly.
