Description

Technical Field

[0001] The present invention relates to the field of quayside container crane equipment, and in particular to a quayside crane trolley installation front beam lighting method and a quayside crane front beam lighting system. Background Art

[0002] A quay crane is a bridge crane that can move along the shore track at the front of the container terminal and align with the ship's cargo space to carry out container loading and unloading operations. As the core loading and unloading equipment of the container terminal, the quay crane needs to be equipped with a high-power floodlight at the seaside end of the front beam to meet the lighting needs of ship operations at night. Traditional lighting solutions use permanent welded brackets to fix lamps. The bracket protrudes from the structural outline of the front beam. The protruding bracket blocks the trolley's operating mechanism or anti-collision plate, forcing the bracket to be cut and removed before lifting operations and re-welded after the trolley is in place. The bracket needs to be positioned at high altitude during re-welding, and the accuracy is difficult to guarantee. It is easy to cause the lamp angle to deviate or the structural stress to concentrate, resulting in lighting blind spots or weld fatigue cracking. Summary of the Invention

[0050] The following combination Figures 1 to 18 The method for lighting the front beam while taking into account the installation of the quay crane trolley provided in this embodiment is described in detail.

[0051] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 14 The embodiment of the present invention provides a lighting method for the front beam 11 while taking into account the installation of the quay crane trolley, comprising:

[0052] A floodlight installation space 110 is provided at a preset position of the seaside railing 100 of the front quay crane beam 11, and a cross railing 120 is detachably provided in the middle of the floodlight installation space 110 in the height direction. A base pre-weld 300 for mounting a floodlight bracket 500 is pre-welded on the upper surface 200 of the front quay crane beam directly below the cross railing 120. The base pre-weld 300 and the installation position of the cross railing 120 overlap in vertical projection, and the base pre-weld 300 can avoid the lifting of the trolley assembly 900 in the lateral direction.

[0053] When there is no lighting requirement, the cross railing 120 is installed to form a continuous protective railing 100, and the trolley assembly 900 is hoisted without the protruding structure; when there is a lighting requirement, the trolley assembly 900 is hoisted first, then the cross railing 120 is removed and the floodlight bracket 500 is installed on the base pre-welded part 300, and the floodlight bracket 500 is used to install the floodlight 800.

[0054] It should be noted that the "seaside railing 100 of the quay crane front beam 11" refers to the railing installed on the ocean side of the quay crane front beam. It primarily serves as a safety barrier, preventing people and objects from accidentally falling from the seaside, ensuring the safety of personnel and equipment in the seaside area during quay crane operations. The "upper surface 200 of the quay crane front beam" refers to the upward, horizontally extending flat surface of the quay crane front beam. This is a critical load-bearing and operating area of ​​the quay crane, where various equipment, such as floodlight bases, can be installed, providing support and a foundation for equipment installation during quay crane operations.

[0055] A floodlight installation space 110 is provided at a preset location on the seaside railing 100 of the quay crane front beam 11. A removable crossrail 120 can be installed in the center of the space. This design provides structural flexibility, allowing the crossrail 120 to be removed and installed as needed. A pre-welded base 300 is pre-welded to the upper surface 200 of the quay crane front beam directly below the crossrail 120. This pre-welded base 300 vertically overlaps the crossrail 120 installation location and allows for the trolley assembly 900 to be installed laterally. This provides a secure mounting point for the floodlight bracket 500 without interfering with the operation of the trolley assembly 900.

[0056] When there is no lighting requirement, the installation of the cross railing 120 provides continuous protection, ensuring personnel safety. The lack of protruding structures allows for smooth installation of the trolley assembly 900, avoiding rework due to structural interference and improving operational efficiency. When lighting is required, the trolley assembly 900 is first installed, followed by the removal of the cross railing 120 to install the floodlight bracket 500. The pre-welded base 300 is laterally positioned to allow for the installation of the trolley assembly 900, resolving the issue of interference between the installation of the trolley assembly 900 and the bracket for the floodlight 800. Furthermore, the design of the floodlight installation space 110 and the removable cross railing 120 can flexibly adapt to different lighting requirements and railing 100 arrangements, ensuring that the lighting installation of the gantry crane front beam 11 and the installation of the trolley assembly 900 do not interfere with each other. This makes operation simple and convenient, effectively reducing construction difficulty and cost, and improving the overall operational fluidity and safety.

[0057] Reference Figure 2 and Figure 4 In this embodiment, mounting members 400 are respectively fixed on the railing 100 columns on both sides of the floodlight installation space 110 , and both ends of the cross railing 120 are detachably mounted on the two mounting members 400 .

[0058] Mounting fixtures 400 are fixed to the railings 100 on either side of the floodlight installation space 110, allowing for removable installation at both ends of the crossrail 120. This provides a stable structure and convenient assembly and disassembly. When lighting is not required, the crossrail 120 can be quickly installed to provide continuous protection, ensuring personnel safety and ensuring standardized operation. When lighting is required, it can be quickly removed to free up space for the floodlight bracket 500, avoiding interference with the trolley assembly 900 installation and reducing rework. This design flexibly adapts to different working conditions, effectively improving the efficiency and safety of both the lighting installation on the gantry crane front beam 11 and the trolley assembly 900 installation.

[0059] In this embodiment, the mounting member 400 is provided with mounting holes, and two ends of the cross railing 120 are movably provided with two mounting holes of the mounting member 400 .

[0060] Mounting member 400 is provided with mounting holes, through which both ends of crossbar 120 are movably inserted, greatly improving the convenience of assembly and disassembly. Crossbar 120 can be installed and removed with a simple plug-in and pull-out operation. When there is no lighting requirement, continuous guardrail 100 can be quickly constructed to ensure safe operation. When lighting is required, it can be quickly removed to make room for the installation of floodlight bracket 500, effectively avoiding interference with the lifting of trolley assembly 900, reducing rework caused by structural conflicts, improving overall operation efficiency, and reducing construction costs and difficulty.

[0061] In other embodiments, the mounting member 400 may also be provided with a clamping member, and both ends of the crossbar 120 are detachably clamped on the clamping members of the two mounting members 400 .

[0062] The clamping operation is simple, eliminating the need for precise hole alignment, allowing for quick installation and removal, significantly improving work efficiency. Furthermore, the clamping is stable, ensuring the protective performance of the railing 100, balancing ease of installation with safety.

[0063] Reference Figure 5 、 Figure 12 ,、 Figure 17 and Figure 18 In this embodiment, the base pre-weld 300 includes a base 310 and a bottom plate 320; the base 310 is welded to the upper surface 200 of the front beam of the quay crane in the floodlight installation space 110, and the bottom plate 320 is fixed on the base 310. The bottom plate 320 is provided with a base threaded hole 330 for connecting the floodlight bracket 500.

[0064] The pre-welded base 300 is split into a base 310 and a bottom plate 320. The base 310 is welded to the upper surface 200 of the front girder of the quay crane, ensuring the stability of the overall structure and a reliable connection to the girder 11, capable of withstanding the weight and external forces of the floodlight 800 and the bracket. The bottom plate 320 is fixed to the base 310 and provided with a base threaded hole 330, providing a precise and stable connection point for the floodlight bracket 500, facilitating quick installation and removal of the floodlight bracket 500 and improving installation efficiency. This structural design also provides a clear division of labor among the various components, enhancing the durability and reliability of the overall structure and reducing subsequent maintenance costs.

[0065] Reference Figure 7 、 Figure 8 、 Figure 9 、 Figure 12 、 Figure 15 and Figure 16 In this embodiment, the floodlight bracket 500 includes a bracket plate 510, an L-shaped bent pipe and a floodlight mounting plate 530; the two end portions of the L-shaped bent pipe are vertically fixed to the bracket plate 510 and the floodlight mounting plate 530 respectively, and the bracket plate 510 is provided with a bracket hole 511 for connecting with the base pre-weld 300.

[0066] The floodlight bracket 500 consists of a bracket plate 510, an L-shaped elbow, and a floodlight mounting plate 530, with a simple and stable structure. The two ends of the L-shaped elbow are fixed vertically to form a stable support between the plates, which can effectively withstand the weight of the floodlight 800 and external forces, ensuring lighting stability. The bracket plate 510 is provided with a bracket hole 511, which can be precisely connected to the base pre-welded part 300, making installation and disassembly convenient and improving construction efficiency. At the same time, this modular design makes it easy to adjust the position and angle of the floodlight 800 according to actual needs, flexibly adapting to different lighting scenarios, reducing installation difficulty and cost, and improving overall practicality and economy.

[0067] Reference Figure 8 、 Figure 10 and Figure 11 In this embodiment, a railing bracket 600 is used to connect the L-shaped elbow and the railing 100 column on one side of the floodlight installation space 110. One end of the railing bracket 600 is fixed to the vertical section of the L-shaped elbow through a U-shaped bolt clamp, and the other end of the railing bracket 600 is connected to the railing 100 column adjacent to the vertical section of the L-shaped elbow.

[0068] The use of a handrail bracket 600 to connect the L-shaped bend pipe and the handrail 100 column enhances the stability of the overall structure. A U-bolt clamp is used to fix one end of the handrail bracket 600 to the vertical section of the L-shaped bend pipe. This is convenient to install and firmly fixed, effectively dispersing the stress generated by the floodlight 800 and the bracket, and preventing deformation of the L-shaped bend pipe. The other end is connected to the adjacent handrail 100 column to form a stable triangular support system, further enhancing wind and vibration resistance. At the same time, this design does not require complex processing, is relatively low in cost, and does not affect operations such as the hoisting of the trolley assembly 900, thus ensuring the reliable operation of the quay crane front beam lighting system 10.

[0069] Reference Figure 11 In this embodiment, a first screw hole 610 and a second screw hole 620 are arranged side by side at one end of the railing bracket 600, and the first screw hole 610 and the second screw hole 620 are used for passing the two ends of the U-shaped bolt through and locking; a third screw hole 630 is provided at the other end of the railing bracket 600, and the third screw hole 630 is connected to the railing 100 column adjacent to the vertical section of the L-shaped elbow through a bolt.

[0070] One end of the railing bracket 600 is provided with a first screw hole 610 and a second screw hole 620 spaced side by side for U-bolts to pass through and lock. This design makes the U-bolt flexible and stable to install, and the position can be fine-tuned according to actual needs to ensure a tight connection with the vertical section of the L-shaped elbow, effectively distributing the force. The third screw hole 630 at the other end is connected to the railing 100 column via bolts, making installation and disassembly easy and convenient for later maintenance. The overall structure forms a stable support, enhancing the wind and vibration resistance of the floodlight bracket 500, ensuring the stable operation of the lighting system, while reducing installation difficulty and cost, and improving work efficiency.

[0071] Specifically, the first screw hole 610 , the second screw hole 620 and the third screw hole 630 are elongated holes, which are convenient for adjusting the corresponding positions for fixation.

[0072] Reference Figure 9 and Figure 13 In this embodiment, a washer 540 is installed on the floodlight mounting plate 530 , and the floodlight 800 is fixed by a bolt passing through the washer 540 .

[0073] Install the washer 540 on the floodlight mounting plate 530 and secure the floodlight 800 with bolts. The washer 540 increases the contact area between the bolt and the floodlight 800, making the force distribution more even, effectively preventing damage to the floodlight 800 due to excessive local force, and improving its installation stability. At the same time, the washer 540 acts as a buffer and shock absorber, reducing the impact of vibrations generated by equipment operation on the floodlight 800 and reducing the risk of loosening. Furthermore, this installation method facilitates the removal and replacement of the floodlight 800, making subsequent maintenance more convenient and reducing maintenance costs. It ensures the long-term stable operation of the floodlight 800 and provides reliable lighting support for quay crane operations.

[0074] In this embodiment, a shock-absorbing rubber pad is installed between the bracket plate 510 and the base pre-weld 300 , and the shock-absorbing rubber pad is provided with a through hole for the bolt to pass through.

[0075] A shock-absorbing rubber pad with a through hole is installed between the bracket plate 510 and the base pre-weld 300. When the floodlight bracket 500 is subjected to external vibration or vibration generated during equipment operation, the shock-absorbing rubber pad can effectively absorb and buffer the vibration energy with its own elasticity, reducing the vibration transmitted to the floodlight 800, reducing the risk of damage, loosening, or lighting deviation of the floodlight 800 due to vibration, and extending its service life. At the same time, the through hole design does not hinder the bolt connection between the bracket plate 510 and the base pre-weld 300, ensuring the stability of the installation. In addition, it can also reduce the noise generated by vibration, improve the comfort of the working environment, and ensure the stable and reliable operation of the lighting system.

[0076] Reference Figure 15 and Figure 16In this embodiment, a U-shaped round steel bar 521 is fixed to each of the vertical section and the horizontal section of the L-shaped elbow.

[0077] U-shaped round steel tie bars 521 are fixed to the vertical and horizontal sections of the L-shaped elbow, effectively restraining and organizing the cables of the floodlight 800. The cables can be threaded through the tie bars in an orderly manner, avoiding tangled connections. This not only adds a neat and aesthetically pleasing overall structure but also facilitates later inspection, maintenance, and replacement of the cables, improving operational efficiency. Furthermore, the tie bars prevent damage to the cables from shaking and friction, ensuring their insulation performance and service life. This ensures stable power supply to the floodlight 800, reduces lighting failures caused by cable problems, and provides continuous and reliable lighting for quay crane operations.

[0078] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 14 The embodiment of the present invention further provides a quay crane front beam lighting system 10 for implementing a method for lighting a front beam 11 while taking into account the installation of a quay crane trolley. The quay crane front beam lighting system 10 includes a cross railing 120, a pre-welded base part 300, and a floodlight bracket 500. The cross railing 120 is used to be detachably mounted at the middle height position of the railing 100 columns on both sides of the floodlight installation space 110; the pre-welded base part 300 is used to be pre-welded to the upper surface 200 of the quay crane front beam in the floodlight installation space 110; and the floodlight bracket 500 is used to be detachably mounted on the pre-welded base part 300.

[0079] Among them, the cross railing 120 and the floodlight bracket 500 overlap in the vertical direction, and one of them can be installed alternatively: when the cross railing 120 is installed, the cross railing 120 covers the base pre-weld 300 area; when the floodlight bracket 500 is installed, the cross railing 120 is removed to expose the base pre-weld 300.

[0080] Either the cross railing 120 or the floodlight bracket 500 is installed with their projections overlapping. Installing the cross railing 120 can provide protection and cover the base pre-weld 300. When installing the floodlight bracket 500, the cross railing 120 is removed to expose the base pre-weld 300. The functions can be flexibly switched to meet the lighting and protection needs of different operation stages of the quay crane.

[0081] According to the present embodiment, a method for lighting the front beam 11 while taking into account the installation of the quay crane trolley is provided. The working principle of the method for lighting the front beam 11 while taking into account the installation of the quay crane trolley includes: around the space of the quay crane front beam 11, the cross railing 120 and the floodlight bracket 500 are selectively installed to achieve function switching. When no lighting operation is required, such as when the quay crane trolley is installed, the cross railing 120 is installed in the middle of the railing 100 columns on both sides of the floodlight installation space 110 to form a continuous guardrail structure to play a protective role; when lighting is required, the cross railing 120 is removed to expose the base pre-weld 300, and then the floodlight bracket 500 is detachably installed on the base pre-weld 300, and then the floodlight 800 is installed to achieve lighting. Through this flexible installation and disassembly method, the quay crane trolley installation operation and the lighting requirements of the front beam 11 are taken into account, thereby improving space utilization and operation convenience.

[0082] The lighting method for the front beam 11 provided by this embodiment while taking into account the installation of the quay crane trolley has at least the following advantages:

[0083] By selectively installing either the cross railing 120 or the floodlight bracket 500, the same space can play a protective and lighting role in different operation stages, without the need to open up additional space for lighting equipment installation, which greatly improves the utilization efficiency of the limited space of the quay crane front beam 11.

[0084] Installation and removal are simple: operators only need to disassemble and assemble the horizontal railing 120 degrees to complete the functional conversion in a short time, without the need for complex commissioning and installation. Compared with traditional functional switching methods that require multiple steps and a lot of time, this solution greatly improves work efficiency and reduces equipment downtime, saving companies a considerable amount of time and costs, with significant economic benefits and technical advantages.

[0085] This effectively reduces the cost of the quay crane front beam lighting system 10. On the one hand, by sharing installation space and parts of the structure, the amount of materials used is reduced, lowering the equipment procurement cost. On the other hand, the simplified structure makes equipment maintenance and servicing easier, reducing the workload and maintenance costs of maintenance personnel.

[0086] The above description is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technology in this field within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention.
