Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical connection devices, and specifically relates to a lightweight and durable connection device. Background Art

[0002] In modern industrial production, the efficient operation of transfer vehicles in factories is of great significance for improving logistics efficiency and reducing production costs. Transfer vehicles need to be frequently connected to and separated from material transfer and storage racks. Therefore, the performance of the connection device directly affects the transfer efficiency and the service life of the equipment. Existing connection devices usually have problems such as large volume, heavy weight, complex installation, and insufficient durability. These problems result in a longer connection process, increasing the workload of operators and also raising the maintenance cost. In addition, traditional connection devices are prone to failure due to wear during long-term use. If not replaced or repaired in a timely manner, it may affect the normal progress of production.

[0003] After retrieval, a car front door lock device with the publication number CN107700973B was disclosed on July 4, 2023. This patent relates to a car front door lock device, which achieves the effects of easy operation and durability for opening and closing doors through the design of components such as ratchets, pawls, and buffer blocks, and has an anti-mislocking function. However, this technical solution is mainly aimed at the application scenario of car door locks. Its structure is relatively complex and the number of components is large, resulting in a relatively large overall weight and inconvenient installation. In addition, due to the inclusion of multiple hinged and spring components in its design, long-term high-frequency use may cause component fatigue or loosening, thereby affecting durability and reliability, and it is difficult to directly meet the rapid connection requirements between factory transfer vehicles and material storage racks.

[0004] After retrieval, a snap-on frame box with side protection with the publication number CN118025621B was disclosed on July 5, 2024. This patent proposes a frame box structure mainly composed of snap plates and guardrails, which realizes the fixation of the guardrails through a locking device and enhances the structural strength, while emphasizing the characteristics of being lightweight and durable. However, this technical solution pays more attention to the overall assembly and side protection function of the frame box. Although its snap-on connection method is convenient for disassembly, its load-bearing capacity is limited and cannot meet the high-load and high-frequency connection requirements between transfer vehicles and material storage racks. In addition, this connection method requires a high degree of operation precision, and may be insecure due to human factors in actual applications, thus affecting safety.

[0005] The above problems indicate that there are still certain deficiencies in the existing connection devices in terms of lightweight design, durability guarantee, and fast and reliable connection, especially when dealing with the special requirements of high-intensity and high-frequency use in industrial scenarios. Therefore, the present invention aims to provide a lightweight and durable connection device, which reduces the number of components through optimized structural design, improves the installation convenience, and at the same time enhances the bearing capacity and anti-fatigue performance of the connection device to meet the requirements of efficient and reliable connection devices for in-plant material handling. Summary of the Invention

[0006] Aiming at the defects of low connection efficiency, easy wear of the device, short service life, and high maintenance cost existing in the connection process between the existing transfer vehicle and the material storage rack, the present invention provides a lightweight and durable connection device. Through optimized structural design and material selection, the connection device achieves the technical goals of fast connection and long durability, while significantly reducing the manufacturing and maintenance costs.

[0007] The present invention provides a lightweight and durable connection device, which includes a connector, a wear-resistant disc, a through pin, and a fastening bolt. As the main component, the connector has an overall size of 290mm×205mm, a front-end width of 160mm, and a height of 25mm; the rear-end width is 170mm, and the height is 120mm. Further, there are four holes with a diameter of 11mm in the middle part of the connector, and the center distances of the holes are 35mm and 78mm respectively; there are two round holes with a diameter of 40mm at the front end, and a round hole with a diameter of 35mm at the rear end. All unmarked chamfers are processed to the C2 specification. Among them, the connector is made of Q355 material to ensure its high strength and toughness. The connector is installed between the transfer vehicle and the material storage rack to play a role in fast connection.

[0008] Further, the wear-resistant disc has a diameter of 120mm, a thickness of 25mm, a round hole with a diameter of 35mm in the center, and four holes with a diameter of 11mm are evenly distributed around it, and the center distance of the holes is 78mm. The wear-resistant disc is made of ZGMn13 material, which has excellent wear resistance. In particular, the wear-resistant disc is fixed on the connector by screws and nuts. When wear occurs in a certain direction due to long-term use, it can be disassembled and rotated to another direction for continued use. One wear-resistant disc can be rotated up to four times, thus extending the service life of the connector and reducing the maintenance frequency and cost.

[0009] Furthermore, the total length of the dowel pin is 285 mm, the head diameter is 60 mm, and the length is 70 mm; the diameter of the middle part is 40 mm, and the length is 28 mm; the diameter of the tail is 28 mm, and the length is 230 mm. The dowel pin is made of Q355 material, with high strength and durability. Among them, the dowel pin is used to quickly connect the connector to the transfer vehicle and the material storage rack respectively. During the connection process, the dowel pin can be quickly removed or inserted to achieve the quick separation or connection of the transfer vehicle and the material storage rack.

[0010] Furthermore, the fastening bolts are used to fix the wear-resistant disc to the connector to ensure a firm connection between the two. The number of fastening bolts is 12, and their specifications and materials are matched according to actual usage requirements to ensure the reliability and stability of the connection.

[0011] The assembly method and working principle of the present invention are as follows: S1, install the connector as the main component between the transfer vehicle and the material storage rack; S2, fix the wear-resistant disc to the connector with screws and nuts to form a protective layer to prevent the connector from being directly worn; S3, connect the transfer vehicle and the material storage rack respectively through dowel pins at the front and rear ends of the connector. When it is necessary to connect the transfer vehicle and the material storage rack, first remove the dowel pins from the front and rear ends of the connector, then pass the connector through the connection part of the material transfer and storage rack, and quickly insert the dowel pins to complete the connection. The entire connection process can be completed within one minute, with convenient and reliable operation. In addition, when a certain direction of the wear-resistant disc is worn, it can be removed and rotated to another direction for continued use until all directions are worn before replacement, thus significantly improving the service life of the device.

[0012] In particular, the present invention realizes the specific implementation details of the technical solution through the following innovative points. First, the connector adopts an optimized size design and material selection, combined with the multi-directional use characteristics of the wear-resistant disc, effectively solving the problems of easy wear and short service life of traditional connection devices. Second, the design of the dowel pin enables the connector to be quickly removed or inserted, greatly shortening the connection time. Third, the reasonable arrangement of the fastening bolts ensures a firm connection between the wear-resistant disc and the connector, avoiding connection failure caused by loosening.

[0013] The beneficial effects of the present invention are as follows: Through the above technical solutions, the connection efficiency and reliability between the transfer vehicle and the material storage rack are significantly improved. First, the multi-directional use design of the wear-resistant disc significantly extends the service life of the connector, reducing the maintenance frequency and cost. Second, the quick plugging and unplugging function of the dowel pin realizes the quick connection and separation of the transfer vehicle and the material storage rack, greatly shortening the transfer time. Third, the present invention adopts a pure mechanical structure, without additional energy or complex equipment, with low manufacturing cost and is suitable for large-scale popularization and application. Finally, the device has a simple structure, convenient operation, and firm connection, and is suitable for frequent transfer scenarios in the factory.

[0014] In summary, through optimizing the structural design and material selection, the present invention provides a lightweight and durable connecting device, effectively solving the problem of rapid connection between the transfer vehicle and the material storage rack, and having remarkable technological progress and practical value.

[0022] The present invention provides a lightweight and durable connecting device, which realizes the rapid connection between the transfer vehicle and the material storage rack through optimizing the structural design and material selection. The following details the specific embodiments of the present invention with reference to the attached Figures 1 to 5 drawings and reference numerals. The embodiments cover the structural features, assembly methods and operation steps in the actual use process of the connector, wear-resistant disc, pin and fastening bolt.

[0023] Such as Figure 1As shown, the connector 1, as the core component of the present invention, has an overall size of 290mm × 205mm, a front-end width of 160mm, a height of 25mm, a rear-end width of 170mm, and a height of 120mm. Four holes with a diameter of 11mm are provided in the middle part of the connector 1, and the center distances of the holes are 35mm and 78mm respectively; two round holes with a diameter of 40mm are provided at the front end, and one round hole with a diameter of 35mm is provided at the rear end. All chamfers not specified are machined to the C2 specification. The connector 1 is made of Q355 material, which has high strength and toughness, ensuring that the connector is not easily deformed or damaged during long-term use. The design of the connector 1 fully considers the installation convenience and practicality, and can be quickly connected to the transfer vehicle 5 and the material storage rack 6 through the round holes at the front end and the rear end respectively. Specifically, the two round holes with a diameter of 40mm at the front end are used to install the through pin 3, and the round hole with a diameter of 35mm at the rear end is used to fix another through pin 3, thereby realizing the firm connection between the transfer vehicle 5 and the material storage rack 6.

[0024] The structure of the wear-resistant disc 2 is as Figure 2 shown. Its diameter is 120mm, thickness is 25mm, and a round hole with a diameter of 35mm is provided at the center. Four holes with a diameter of 11mm are evenly distributed around it, and the center distance of the holes is 78mm. The wear-resistant disc 2 is made of ZGMn13 material, which has excellent wear-resistant performance and can maintain a long service life under high-frequency use conditions. The wear-resistant disc 2 is fixed on the connector 1 through screws 7 and nuts 8 to form a protective layer to prevent the connector 1 from being directly worn. When a certain direction of the wear-resistant disc 2 is worn due to long-term use, it can be removed and rotated to another direction for continued use. A wear-resistant disc can be replaced in direction up to four times, thus significantly extending the service life of the connector 1 and reducing the maintenance frequency and cost. The multi-directional use design of the wear-resistant disc 2 not only improves the economy of the device but also effectively reduces the downtime caused by frequent replacement of parts.

[0025] The structure of the through pin 3 is as Figure 3 shown. Its total length is 285mm, the head diameter is 60mm, and the length is 70mm; the middle part has a diameter of 40mm and a length of 28mm; the tail diameter is 28mm and the length is 230mm. The through pin 3 is made of Q355 material and has high strength and durability. The design of the through pin 3 enables the connector 1 to be quickly removed or inserted, greatly shortening the connection time. Specifically, the head of the through pin 3 has a larger diameter for easy manual operation, the design of the middle part ensures that it can firmly pass through the round hole of the connector 1, and the slender structure of the tail ensures that the through pin 3 will not fall off easily after being inserted. The quick plug-and-play function of the through pin 3 is the key to realizing the quick connection between the transfer vehicle 5 and the material storage rack 6, and the entire connection process can be completed within one minute.

[0026] The number of fastening bolts 4 is 12, and their specifications and materials are matched according to the actual usage requirements to ensure the reliability and stability of the connection. The fastening bolts 4 are used to fix the wear-resistant disc 2 and the connector 1, ensuring a firm connection between the two. The reasonable arrangement of the fastening bolts 4 avoids connection failure problems caused by loosening, further improving the overall reliability of the device.

[0027] The assembly method and working principle of the present invention are as follows: First, install the connector 1 as the main component between the transfer vehicle 5 and the material storage rack 6, ensuring that the front end and the rear end of the connector 1 are respectively aligned with the connection points of the transfer vehicle 5 and the material storage rack 6. Then, fix the wear-resistant disc 2 on the connector 1 through screws 7 and nuts 8 to form a protective layer to prevent the direct wear of the connector 1. Subsequently, connect the transfer vehicle 5 and the material storage rack 6 respectively through the pin 3 at the front end and the rear end of the connector 1. When it is necessary to connect the transfer vehicle 5 and the material storage rack 6, first remove the pin 3 from the front end and the rear end of the connector 1, then pass the connector 1 through the connection part of the material transfer and storage rack 6, and quickly insert the pin 3 to complete the connection. The entire connection process can be completed within one minute, with convenient and reliable operation. In addition, when a certain direction of the wear-resistant disc 2 is worn, it can be removed and rotated to another direction for continued use until all directions are worn before replacement, thus significantly increasing the service life of the device.

[0028] In the actual application scenario, the connection device of the present invention shows significant technical advantages. For example, during the material transfer process in a certain factory, the transfer vehicle 5 needs to be frequently connected and separated from the material storage racks 6 at different positions. The traditional connection method usually takes a long time, and the connection device is easily worn quickly due to long-term friction, resulting in a high maintenance frequency and increased costs. After adopting the connection device of the present invention, the connection time between the transfer vehicle 5 and the material storage rack 6 is significantly shortened, and each connection can be completed in less than one minute. At the same time, due to the multi-directional use design of the wear-resistant disc 2, the service life of the connector 1 is significantly extended, the maintenance frequency is greatly reduced, and a large amount of maintenance costs are saved. In addition, the present invention adopts a pure mechanical structure, without the need for additional energy or complex equipment, and has a low manufacturing cost, making it suitable for large-scale popularization and application.

[0029] In order to more intuitively display the actual application effect of the present invention, Figure 5 shows the rapid connection process of the connector 1 with the transfer vehicle 5 and the material storage rack 6 through the pin 3. It can be seen from the figure that the front end of the connector 1 is firmly connected to the transfer vehicle 5 through the pin 3, and the rear end is connected to the material storage rack 6 through another pin 3. The entire connection process is simple and fast. The operator only needs to insert the pin 3 into the corresponding round hole to complete the connection, without the need to rely on any tools or equipment. This rapid connection method not only improves work efficiency but also reduces safety hazards caused by improper connection.

[0030] In summary, through optimizing the structural design and material selection, the present invention provides a lightweight and durable connection device, solving the problem of rapid connection between the transfer vehicle and the material storage rack. The optimized design of the connector 1 ensures the strength and durability of the device. The multi-directional use characteristics of the wear-resistant disc 2 significantly extend the service life of the device. The quick insertion and extraction function of the through pin 3 greatly shortens the connection time. The reasonable arrangement of the fastening bolts 4 ensures the reliability of the connection. The present invention has significant technological progress and practical value, is applicable to the frequent transfer scenarios within the factory, and can effectively improve the work efficiency and reduce the maintenance cost.
