Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and more specifically, to an adjustable lighting device for a gantry crane. Background Technology

[0002] A gantry crane is a type of bridge crane, consisting of two parallel columns and a crossbeam. It is typically used for lifting and moving heavy objects outdoors or in large indoor spaces. Gantry cranes require lighting equipment to ensure operators can clearly see the work area and the load in low-light conditions, improving safety and efficiency. Lighting equipment is usually installed on both sides of the main beam, in the trolley and hook areas, and in the operator's cab, ensuring comprehensive lighting coverage, reducing operational errors and accident risks, and protecting the safety of personnel and equipment.

[0003] Most existing lighting equipment on gantry cranes is fixedly installed, with fixed illumination angles and lamp models and functions, making it inconvenient to flexibly adjust and replace it according to actual usage needs. This fixed installation method limits the adaptability of the lighting equipment, making it impossible to adjust the illumination angle and intensity according to different working environments and operational requirements, resulting in poor lighting effects in some situations, affecting operational safety and efficiency;

[0004] Furthermore, in existing technologies, gantry cranes are quite tall, requiring maintenance personnel to climb to repair damaged lighting equipment. This not only increases the difficulty of maintenance but also introduces significant safety risks. Working at height necessitates the use of ladders or aerial work platforms, increasing the risk of accidents and threatening the personal safety of maintenance personnel. Therefore, existing methods for installing and maintaining lighting equipment are clearly insufficient in terms of convenience and safety. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In view of the problems existing in the prior art, this utility model provides an adjustable lighting device for a gantry crane, so as to solve the technical problems mentioned in the background art that the adjustable lighting device for a gantry crane is not convenient to flexibly adjust the lighting function during use and is not convenient to maintain.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An adjustable lighting device for a gantry crane includes a mounting base. A mounting shaft is mounted on the mounting base via bearings, and an adjusting motor is mounted in conjunction with the mounting shaft. Multiple sets of mounting brackets are evenly arranged on the mounting shaft. Connecting brackets are horizontally and rotatably mounted on the mounting brackets. Lamp holders are located on the outer sides of the connecting brackets, and lighting lamps are mounted on the lamp holders. Two sets of lifting ropes are symmetrically arranged on the top of the mounting base. An equipment box is located above the mounting base. A winding shaft is mounted inside the equipment box via bearing seats, and a winding motor is mounted in conjunction with the winding shaft. A winding wheel is mounted on the winding shaft. The lifting ropes slide into the equipment box and are wound onto the winding wheel. A power supply assembly is located between the equipment box and the mounting base.

[0010] This utility model is further configured such that the power supply component includes a power supply plug, which is disposed at the top of the mounting base and electrically connected to the lamp holder and the regulating motor. A power supply socket is also provided on the equipment box. The power supply plug and the power supply socket are electrically engaged, thereby supplying power to the lamp holder and the regulating motor. The power supply socket can be connected to an external power source. In this utility model, a controller can be installed on the mounting base to control the operation of the lighting and regulating motor. The cooperation and circuit connection structure between the lighting and regulating motor and the controller are existing known technologies and will not be described in detail here. The regulating motor can cooperate with a reducer, etc. This structure is also existing known technology and will not be described in detail here. The rotation angle and number of turns of the mounting shaft are limited; if cable issues are involved, a suitable length of cable can be reserved in advance.

[0011] The present invention is further configured such that a conductive slip ring is provided on the mounting base. One end of the conductive slip ring is electrically connected to the lamp holder located on the mounting shaft via a cable, and the other end is electrically connected to the power supply plug via a cable. The power supply plug is electrically connected to the regulating motor via a cable. Here, the conductive slip ring is installed on the mounting base at the end of the mounting shaft away from the regulating motor. Preferably, the cable passes through the inside of the mounting shaft, with one end connected to the corresponding lamp holder and the other end connected to the conductive slip ring. At the same time, the other end of the conductive slip ring is connected to the power supply plug via a cable. Where the output end of the power supply plug needs to be split, it can be split using a power splitter in the prior art. This is a known prior art and will not be described in detail in this invention. The conductive slip ring is also called a current collector ring, or a slip ring, current collector ring, or current bus ring. It can be used in any electromechanical system that requires continuous rotation while transmitting power and signals from a fixed position to a rotating position. The slip ring can improve system performance, simplify system structure, and prevent wires from twisting during rotation.

[0012] The present invention is further configured such that a cable passage groove is provided at the bottom of the equipment box, the lifting rope extends into the equipment box through the cable passage groove, and a guide wheel is provided at the position of the cable passage groove. The guide wheel allows the lifting rope to pass vertically through the cable passage groove, which can reduce the wear of the lifting rope during use and improve the stability of the lifting rope when hoisting the mounting base.

[0013] The present invention is further configured such that a limiting block is provided on the top of the mounting base, and the limiting block is engaged with the through groove. The bottom end of the suspension rope is connected and fixed to the limiting block. When the mounting base is pressed against the bottom of the equipment box by the action of the suspension rope, the limiting block will engage into the through groove. Through the mutual limiting engagement between the limiting block and the through groove, the installation stability of the mounting base at the bottom of the equipment box can be improved.

[0014] The present invention is further configured such that an electric push rod is horizontally installed inside the equipment box, and the output end of the electric push rod is provided with a locking block. A locking groove is provided on the limiting block, and the locking block and the locking groove are locked together. After the limiting block at the top of the mounting base passes through the through groove and the top of the mounting base is pressed and fixed against the bottom of the equipment box, the electric push rod can be activated. The electric push rod can control the movement of the locking block, so that the locking block engages into the locking groove on the limiting block. In this way, the locking block and the locking groove can engage and limit the limiting block, thereby further improving the installation stability of the mounting base at the bottom of the equipment box.

[0015] The present invention is further provided that a locking bolt is provided between the connecting frame and the mounting frame. The locking bolt passes through the connecting frame and the mounting frame in sequence and is threaded with a locking nut. The locking bolt and the locking nut can cooperate to achieve adjustable and stable installation of the connecting frame on the mounting frame. A damping pad can be provided between the connecting frame and the mounting frame to enhance the installation stability of the connecting frame on the mounting frame.

[0016] The present invention is further provided that the outer side of the equipment box is provided with a fixing ear, and the fixing ear is provided with a fixing hole. By passing external bolts or fasteners through the fixing hole, the fixing ear can be installed at a suitable lighting position on the gantry crane, thereby realizing convenient and stable fixing of the equipment box on the gantry crane.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides an adjustable lighting device for a gantry crane, which has the following advantages:

[0019] 1. This utility model, by setting up a mounting base and installing lamp holders and lighting lamps on the mounting base via a mounting shaft, allows for the selection of bulbs of different models and functions among multiple lighting lamps. In use, the rotation of the mounting shaft can be controlled by adjusting the motor, thereby enabling the rotation of different lighting lamps. This allows for flexible selection of lighting lamps with different functions or models, improving the adjustment flexibility of the gantry crane when lighting is required during use and enhancing the ease of use.

[0020] 2. Simultaneously, in this utility model, the lamp holder for installing the lighting lamp is rotatably and adjustablely mounted on the mounting bracket located on the mounting shaft via the connecting bracket. During installation, the relative position between the connecting bracket and the mounting bracket can be adjusted, thereby flexibly adjusting the installation angle of the lighting lamp. This allows different lighting lamps to point in different lighting directions as needed, improving the lighting effect and the flexibility of adjustment during installation. After adjusting to the appropriate position, tightening the locking nut secures the connecting bracket on the mounting bracket, thus achieving stable installation of the lighting lamp.

[0021] 3. This utility model features an equipment box above the mounting base, and uses a hoisting method to position the mounting base below the equipment box. During installation, the winding motor can be started, controlling the winding shaft to rotate the winding wheel, thereby winding the lifting rope. This allows the rope to pull the mounting base stably upwards until the power plug on the mounting base engages with the power socket on the equipment box. Simultaneously, the limiting block at the top of the mounting base engages with the corresponding cable groove, ensuring stable installation of the mounting base at the bottom of the equipment box. This improves the stability of the lighting fixture during use. Furthermore, when maintenance is required, the winding motor can be reversed to unwind the winding wheel, allowing the mounting base to descend stably under its own weight, facilitating maintenance. This eliminates the need for maintenance personnel to climb to higher positions when repairing lighting devices on gantry cranes, significantly improving maintenance convenience.

The rotation angle and number of turns of the mounting shaft 2 are limited. If cable issues are involved, a suitable length of cable can be pre-installed.

[0033] Furthermore, this utility model provides a conductive slip ring 15 on the mounting base 1.

[0039] In summary:

[0040] This utility model sets up a mounting base 1, and installs lamp holders 6 and lighting lamps 7 on the mounting base 1 via mounting shaft 2. It allows for the selection of different models and functions of bulbs among multiple lighting lamps 7. In use, the rotation of mounting shaft 2 can be controlled by adjusting motor 3 to achieve the rotation of different lighting lamps 7. This allows for flexible selection of lighting lamps 7 with different functions or models, improving the adjustment flexibility and ease of use when lighting is required during the operation of the gantry crane.

[0041] Meanwhile, in this utility model, the lamp holder 6 used to install the lighting lamp 7 is rotatably and adjustablely mounted on the mounting bracket 4 located on the mounting shaft 2 via the connecting bracket 5. During installation, the relative position between the connecting bracket 5 and the mounting bracket 4 can be adjusted, thereby flexibly adjusting the installation angle of the lighting lamp 7 during installation. This allows different lighting lamps 7 to point to different lighting directions as needed, improving the lighting effect and the flexibility of adjustment during installation. After adjusting to the appropriate position, the locking nut 23 is tightened to lock and fix the connecting bracket 5 on the mounting bracket 4, thereby achieving stable installation of the lighting lamp 7.

[0042] This utility model provides an equipment box 9 above the mounting base 1 and uses a hoisting method to place the mounting base 1 below the equipment box 9. During installation, the winding motor 11 can be started, and the winding shaft 10 is controlled by the winding motor 11 to drive the winding wheel 12 to rotate, thereby winding the lifting rope 8. This allows the lifting rope 8 to pull the mounting base 1 to rise steadily until the power plug 13 on the mounting base 1 is inserted into the power socket 14 on the equipment box 9. At the same time, the limiting block 18 on the top of the mounting base 1 engages into the corresponding wire groove 16, thereby achieving stable installation of the mounting base 1 at the bottom of the equipment box 9. This improves the stability of the lighting lamp 7 during use.

[0043] During this process, when the mounting base 1 is pressed against the bottom of the equipment box 9 by the action of the suspension rope 8, the limiting block 18 will engage into the through groove 16. Through the mutual limiting engagement between the limiting block 18 and the through groove 16, the installation stability of the mounting base 1 at the bottom of the equipment box 9 can be improved.

[0044] Then, the electric push rod 19 is activated. The electric push rod 19 can control the movement of the locking block 20, so that the locking block 20 engages into the locking groove 21 on the limiting block 18. In this way, the locking block 20 and the locking groove 21 can engage and limit the limiting block 18, which can further improve the installation stability of the mounting base 1 at the bottom of the equipment box 9.

[0045] Meanwhile, when the lighting lamp 7 needs to be repaired, the reverse control electric push rod 19 drives the locking block 20 to move out of the locking groove 21 and contact the locking block 20 to limit the limit block 18.

[0046] The reverse control of the winding motor 11 causes the winding wheel 12 to unwind, allowing the mounting base 1 to descend stably under its own weight, thus facilitating the maintenance of the lighting lamp 7. This avoids the need for maintenance personnel to climb to heights when maintaining the lighting device on the gantry crane, improving the convenience of maintenance.
