Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and in particular to a modular clamp and aerial conveying equipment. Background Technology

[0002] With the rapid development of modern logistics and transportation systems, aerial EMS carts, as efficient and flexible automated material handling equipment, have been widely used in smart warehousing and modern production lines. Their core function is to achieve precise and rapid material transfer in three-dimensional space, and this function relies heavily on their end effector—the clamping system.

[0003] Currently, there are two main types of overhead EMS trolley clamping solutions in the industry: one is to directly install the clamp on the timing belt or conductive webbing; the other is to first install a retainer on the timing belt and then fix the clamp on the retainer.

[0004] Among these solutions, the cage-installation method requires replacing the entire cage and clamp assembly when changing the fixture, which is cumbersome, inefficient, and significantly increases the equipment's operating costs. Furthermore, adjusting the cage's level during installation is difficult, affecting the system's positioning accuracy and operational stability. Additionally, many of the electrical control components used in the clamps are integrated inside the aerial trolley itself, increasing the complexity and cost of equipment design and manufacturing. When a clamp malfunctions, maintenance personnel must penetrate deep into the aerial trolley to inspect wiring and components; due to limited operating space and complex maintenance procedures, the difficulty and time cost of on-site maintenance and repair are significantly increased, severely impacting the equipment availability and operational efficiency of the entire warehousing and logistics system.

[0005] Therefore, there is an urgent need for a new type of aerial EMS trolley clamping solution to solve the problems of inconvenient clamp replacement, difficult adjustment, complex maintenance and high cost in the existing technology, so as to better adapt to the efficient, reliable and flexible operation requirements of modern intelligent logistics systems. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0021] Example 1, refer to Figures 1-6 As shown, this utility model provides a modular clamp, including a clamp 1 and electrical control components 2 required for the clamp, and also includes... The cage 3 has an electrical control element 2 mounted on its top and a positioning groove 31 vertically opened on its bottom. The quick-change connector 4 includes a connector body 41, a positioning connecting block 42, and a positioning protrusion 43. One end of the connector body 41 is coaxially provided with a positioning protrusion 43 that matches the positioning groove 31. The connector body 41 is fitted into the positioning groove 31 through the positioning protrusion 43 and connected to the bottom of the retainer 3 by fasteners. The other end of the connector body 41 is symmetrically provided with two positioning connecting blocks 42. Each of the two positioning connecting blocks 42 has a connecting hole 421 for connecting the clamp 1. The locking assembly 5 has multiple sets arranged symmetrically on the retainer 3. The locking assembly 5 includes a first clamp 51, a second clamp 52, a first clamp 53, and a second clamp 54. The first clamp 51 is installed on the top of the retainer 3 and has at least one connecting bolt 55 perpendicular to the retainer 3. Two adjusting nuts 56 are screwed onto the connecting bolt 55. The second clamp 52 has at least one mounting hole. The second clamp 52 is fitted onto the connecting bolt 55 through the mounting hole and clamped between the two adjusting nuts 56. The first clamp 53 and the second clamp 54 are connected to the first clamp 51 and the second clamp 52 respectively by fasteners.

[0022] This utility model discloses a modular clamp that enables rapid replacement of clamp 1 through the quick-change connector 4 on the cage 3. When replacing clamp 1, there is no need to disassemble and replace the entire bulky "cage 3 + clamp 1" assembly, improving the replacement efficiency of clamp 1 and reducing equipment operating costs. Furthermore, the electrical control components 2 are integrated into the top of the cage 3, simplifying the maintenance process and reducing maintenance difficulty and time costs. Simultaneously, the locking assembly 5 allows for flexible adjustment of the level of the cage 3, improving system positioning accuracy and operational stability. The overall structural design is reasonable and highly practical, effectively meeting the operational needs of modern intelligent logistics systems.

[0023] Specifically, the cage 3 serves as a centralized mounting platform for mounting the electrical control components 2 (such as PLC modules, sensor interfaces, relays, and power conversion modules) of the fixture 1. The electrical control components 2 are integrated on the top of the cage 3. Compared with the traditional method of integrating them inside the aerial trolley body, this can significantly reduce the complexity and cost of equipment design and manufacturing. At the same time, when the fixture malfunctions, maintenance personnel can directly check the wiring and components on the top of the cage 3. There is ample operating space, which simplifies the maintenance process and reduces the difficulty and time cost of on-site maintenance and repair.

[0024] The quick-change connector 4 serves as a bridge connecting the mounting platform (cage 3) and the fixture 1, and is the core component enabling rapid replacement of the fixture 1. A high-precision positioning groove 31 is vertically formed at the center of the bottom of the cage 3. The quick-change connector 4, through the precise engagement of the positioning protrusion 43 with the positioning groove 31, allows for rapid positioning and installation of the quick-change connector 4 and the cage 3. The fixture 1 and the quick-change connector 4 can be easily connected using the positioning connecting block 42 and its connecting hole 421. As an independent and standardized component, the quick-change connector 4 decouples the cage 3 from the fixture 1. Compared to the cumbersome combination of "cage 3 + fixture 1" that requires replacement in traditional solutions, only the lower fixture 1 portion needs to be replaced, making the operation convenient and quick. This allows production lines or warehouses to quickly switch between different functions of the fixture 1 (such as clamping, forklift, and hanging types) according to task requirements, greatly improving the flexibility and responsiveness of the equipment.

[0025] The locking assembly 5 securely clamps the entire modular clamp onto the timing belt or conductive webbing of the aerial carriage. Its ingenious design integrates locking and leveling functions. The double-clamping structure increases the contact area between the locking structure and the timing belt or conductive webbing, providing greater friction and ensuring that the clamp 1 does not shift or loosen relative to the timing belt or conductive webbing under high-speed operation and heavy loads. Furthermore, two adjusting nuts 56, one above the other, "clamp" the second clamp 52 in the middle. By rotating these two adjusting nuts 56, the distance between the second clamp 52 and the first clamp 51 can be precisely controlled, thereby adjusting the levelness of the retainer 3 and ensuring the accuracy of the clamp 1's position.

[0026] The core components of this structure (cage 3, quick-change connector 4, and locking assembly 5) all adopt a modular design, with standardized interfaces connecting the components. This provides strong versatility and expandability. Firstly, the standardized connection holes of the quick-change connector 4 can be adapted to different types and specifications of clamps (such as mechanical grippers and vacuum suction cups), eliminating the need to modify the cage 3 or locking assembly 5. This meets the diverse clamping needs of materials ranging from metal and plastic parts to packaging. Secondly, the adjustable structure of the locking assembly 5 and the standardized installation interface of the cage 3 can be adapted to different models of overhead EMS carts. Quick adaptation can be achieved simply by adjusting the clamping spacing and installation position of the locking assembly 5 according to the cart specifications. This modular design significantly improves the flexibility of the equipment. Enterprises do not need to purchase dedicated clamping systems for different production lines and materials. Multi-scenario reuse can be achieved through component combination and adjustment, improving the return on investment and better adapting to the core requirements of modern intelligent logistics systems: "efficiency, flexibility, and multi-scenario adaptability."

[0027] Reference Figure 2 As shown, further, four rectangular support seats are vertically arranged on the top of the cage 3. A guide post 6 is coaxially connected to any two diagonally arranged support seats, and a first buffer 7 is coaxially installed on the other two diagonally arranged support seats. Specifically, the body of the aerial trolley is provided with a guide sleeve that works in conjunction with the guide post 6. During the lifting of the cage 3, the guide post 6 is inserted into the guide hole of the guide sleeve, thereby guiding and limiting the modular fixture, ensuring the precise positioning of the modular fixture during operation.

[0028] Furthermore, the first buffer member 7 is cylindrical, and a stepped hole is coaxially formed on the first buffer member 7, which is connected to the support base at the stepped hole by a fastener. The first buffer member 7, which is arranged diagonally, and the second buffer member 8, which is sleeved outside the guide post 6, form a buffering effect, which can absorb the impact energy of operation and reduce the impact of vibration on electrical components and clamping structure. Both the first buffer member 7 and the second buffer member 8 are made of elastic materials such as rubber.

[0029] Furthermore, a base is vertically mounted on one end of the guide post 6, and the base is connected to the support seat by fasteners. The end of the guide post 6 away from the base is machined into a tapered shape. The base enhances the stability of the connection between the guide post 6 and the support seat, and the tapered end is more conducive to guiding and positioning, improving positioning efficiency.

[0030] Furthermore, a second buffer element 8 is coaxially connected to each of the two support seats on which the guide column 6 is installed. The second buffer element 8 is annular and is coaxially connected to the support seat and sleeved on the outside of the guide column 6. The second buffer element 8 cooperates with the first buffer element 7 to further improve the buffering effect, reduce vibration and impact during equipment operation, protect equipment components, and extend the service life of the equipment.

[0031] Reference Figure 6 As shown, the locking components 5 are further provided in four sets, arranged symmetrically in pairs. The symmetrical layout of the four sets of locking components 5 makes the force on the cage 3 more even, improving the stability and reliability of the overall structure of the modular fixture; however, it is not limited to four sets, and can be set according to actual needs.

[0032] Reference Figure 1 As shown, further, a cover plate 9 is included, which covers the top of the retainer 3. The cover plate 9 can protect the electrical control components 2 on the top of the retainer 3 from dust and impact, extend the service life of the electrical control components 2, and ensure the stable operation of the equipment.

[0033] Reference Figure 4 As shown, the cage 3 is further designed as a rectangular plate structure, with two symmetrical inspection ports vertically formed on it. These inspection ports not only reduce the overall weight of the cage but also facilitate maintenance of the components at the top of the cage 3.

[0034] Furthermore, the cage 3 is also provided with several wire passage holes. The wire passage holes are used to organize and arrange the wiring of electrical control components, making the wiring layout more orderly, avoiding faults caused by messy wiring, and also facilitating the inspection and replacement of wiring.

[0035] In embodiment two, this utility model also discloses an aerial conveying device, including a modular clamp as described in embodiment one.

[0036] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
