Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a gantry crane suspension device. Background Technology

[0002] Gantry cranes, as an important lifting and transportation equipment, play an indispensable role in modern factories, workshops and automated production lines, and are widely used for lifting, handling and loading / unloading heavy workpieces.

[0003] In many continuous production processes, such as metal surface treatment, electroplating, or multi-stage cleaning processes, gantry cranes are often used to precisely transfer workpieces from one processing tank to the next. This inter-station transfer operation not only requires the equipment to perform basic vertical lifting and horizontal movement, but also places extremely high demands on the positioning accuracy and stability of the transfer process.

[0004] Existing gantry crane suspension systems often have significant shortcomings when performing such delicate workflow operations. Operators typically rely on visual observation or simple limit switches to control the crane's movement and workpiece descent. This method has low positioning accuracy and cannot meet the demands of high-precision production. During descent, due to the lack of an effective guiding structure, the suspended workpiece is prone to swaying or shifting, easily colliding with the tank walls. This can damage the workpiece and create safety hazards for the equipment. Furthermore, this repetitive alignment process severely impacts the overall production cycle and work efficiency.

[0005] Therefore, this utility model proposes a gantry crane suspension device to overcome the shortcomings of the prior art. Utility Model Content

Detailed Implementation

[0013] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below.

[0014] A gantry crane suspension device, as shown in the reference Figures 1-6 The system includes a horizontal slide rail 3 and a hanger 1 that slides on the horizontal slide rail 3. The horizontal slide rail 3 provides track support for the horizontal movement of the hanger 1. The hanger 1 serves as a carrying platform for carrying subsequent lifting and operating mechanisms. A vertical slide rail 502 is fixedly connected to the bottom of the hanger 1. The suspension assembly 5 slides on the vertical slide rail 502 to achieve lifting and lowering movement in the vertical direction. The suspension assembly 5 includes a suspension beam 501 and a connecting block 505 fixed to the lower part of the suspension beam 501. It also includes a tooling beam mechanism 4 and a cleaning tank 2. The tooling beam mechanism 4 achieves workpiece hoisting through connection with the suspension assembly 5. The tooling beam mechanism 4 includes a tooling beam body 401, with grooves 402 at both ends. A cylindrical crossbeam 510 is provided inside the connecting block 505. The cylindrical crossbeam 510 is detachably engaged with the groove 402. This connection method ensures quick assembly and disassembly and reliable load-bearing between the tooling beam mechanism 4 and the suspension assembly 5. To achieve precise guidance during the workpiece descent, a mounting plate 403 is fixed below the tooling beam mechanism 4. A tapered triangular head 9 is welded to the lower outer side of the mounting plate 403. Correspondingly, a cleaning tank 2 is set at the working position, and V-shaped limiting plates 10 are set on both sides of the cleaning tank 2. When the tooling beam mechanism 4 descends, the conical triangular head 9 and the V-shaped limiting plate 10 cooperate with each other to guide and limit the tooling beam mechanism 4, ensuring that the workpiece enters the cleaning tank 2 smoothly. In order to achieve precise positioning for horizontal movement, an infrared sensor 7 is set on the hanger 1, and a reflector 8 corresponding to the infrared sensor 7 is set at the target position, that is, on the side of the cleaning tank 2. When the hanger 1 moves along the horizontal slide rail 3, the infrared sensor 7 determines that it has reached the predetermined position by detecting the reflector 8, thereby achieving high-precision horizontal positioning. The suspension beam 501 of the suspension assembly 5 is fixedly connected to both ends of the pulley plate 503. The four corners of the pulley plate 503 are provided with pulleys. The pulleys on the pulley plate 503 slide in cooperation with the vertical slide rail 502 fixed below the hanger 1. This multi-point pulley guiding structure ensures the high stability and anti-deflection ability of the suspension assembly 5 during the lifting process along the vertical slide rail 502, so as to realize the lifting drive. The suspension assembly 5 also includes a take-up roller 509, a steel strip roller 506, a steel strip retainer 507, and a steel strip body 508. The take-up roller 509 is mounted on the hanger 1, while the steel strip retainer 507 and the steel strip roller 506 are fixedly connected to the top of the suspension beam 501. One end of the steel strip body 508 is connected to the take-up roller 509, and the other end is fixed to the steel strip retainer 507 after passing around the steel strip roller 506. When the take-up roller 509 rotates, the suspension beam 501 and the entire suspension assembly 5 can be smoothly raised and lowered by winding and unwinding the steel strip body 508. Simultaneously, to ensure a reliable connection between the suspension beam 501 and the lower tooling beam mechanism 4, the suspension assembly 5 also... The system includes a connecting plate 504, which is located on the upper part of the suspension beam 501. The connecting plate 504 and the connecting block 505, which is fixed to the lower part of the suspension beam 501, are clamped and fixed to the suspension beam 501 by screws and bolts. This clamping structure provides a stable installation foundation for the connecting block 505, thereby ensuring that the cylindrical crossbeam 510 can stably transmit the lifting torque to the tooling beam mechanism 4. As for the power source used to drive the winding roller 509 to rotate, those skilled in the art can use various conventional methods such as servo motors and stepper motors. Its connection with the control system and the specific control logic are well-known technologies in the field and will not be described in detail here. In a preferred embodiment, in order to achieve reliable suspension of the workpiece, the tooling beam mechanism 4 also includes a fixing plate 404 and an iron ring 405. The fixing plate 404 is fixed to the side wall of the mounting plate 403 by bolts, and the iron ring 405 is welded to the bottom of the fixing plate 404, providing a stable base for the subsequent connection of the iron chain 406. As another preferred embodiment, in order to achieve quick disassembly and replacement of the suspension chain, it also includes a disassembly assembly 6 and a chain 406. The disassembly assembly 6 is used to detachably connect the iron ring 405 and the end of the chain 406. Specifically, the disassembly assembly 6 includes a fixing sleeve 603 and a plug 601. The fixing sleeve 603 is welded to the bottom of the iron ring 405, and the plug 601 is fixed to the end of the chain 406. A locking block 602 is provided on the side wall of the plug 601. The fixing sleeve 603 has a limiting groove 604 that matches the locking block 602. When connection is required, the plug 601 is inserted into the fixing sleeve 603, and the locking block 602 slides along the limiting groove 604 and finally locks in place. To ensure the connection is tight and prevents loosening, a spring pressure plate 605 is also installed inside the fixing sleeve 603. The spring pressure plate 605 is used to press against the top of the plug 601 and apply a pre-tightening force, thereby completing a quick and reliable connection.

[0015] Working principle: When the workpiece needs to be transferred, the workpiece is first fixed by the iron chain 406 and iron ring 405 at the bottom of the tooling beam mechanism 4. The hooks set below the iron chain 406 firmly lock the top four positions of the workpiece to ensure that it will not fall over or shift during the hoisting process. The cylindrical crossbeam 510 inside the suspension component 5 and the grooves 402 at both ends of the tooling beam body 401 are adapted and engaged to form a stable connection. Next, the winding roller 509 rotates under power drive, winding the steel strip body 508, which drives the steel strip roller 506 and steel strip fixing device 507 fixed on the top of the suspension beam 501 to move upward. The pulleys on the pulley plates 503 on both sides of the suspension beam 501 slide upward along the vertical slide rail 502, so that the suspension assembly 5 carries the tooling beam mechanism 4 and the workpiece below to rise vertically along the vertical slide rail 502, so that the workpiece can be smoothly removed from the current cleaning tank 2. This steel strip winding and unwinding lifting method ensures the stability of the lifting process. After the workpiece is raised to the predetermined height, the hanger 1 moves horizontally along the horizontal slide rail 3 under the action of the driving force until the infrared sensor 7 on the hanger 1 detects the reflector 8 next to the target cleaning tank 2. The coordinated action of the infrared sensor 7 and the reflector 8 ensures the accurate alignment of the hanger 1 in the horizontal direction. After precise positioning is completed, the take-up roller 509 rotates in the opposite direction to release the steel strip body 508, causing the suspension assembly 5 to drive the tooling beam mechanism 4 and the workpiece to descend along the vertical slide rail 502. When the workpiece approaches the target cleaning tank 2, the conical triangular head 9 welded to the outside of the mounting plate 403 below the tooling beam mechanism 4 begins to contact and cooperate with the V-shaped limiting plates 10 on both sides of the cleaning tank 2 to precisely guide and limit the descending workpiece, guiding the workpiece to smoothly and accurately immerse into the next cleaning tank 2, completing one cycle operation. To facilitate the quick assembly and disassembly of the chain 406, the assembly and disassembly component 6 comes into play. When it is necessary to replace or disassemble the chain 406, the operating plug 601 causes the locking block 602 to slide and rotate in the limiting groove 604 inside the fixing sleeve 603 and disengage from the locking position. With the assistance of the spring pressure plate 605, the chain 406 can be quickly separated from the iron ring 405 or quickly connected.
