Description

Technical Field

[0001] This utility model relates to the field of telescopic fork manufacturing, specifically to a telescopic fork with an anti-splash oil device for use in inverted loading conditions. Background Technology

[0002] With the accelerating pace of economic globalization, the enormous potential of automated storage and retrieval systems (AS / RS) is attracting increasing attention. As a crucial component of logistics centers, AS / RS directly impacts enterprise strategies and plans, directing and adjusting corporate actions. Due to their high storage and retrieval efficiency, AS / RS can effectively connect off-site production processes, forming an automated logistics system within storage. This creates a planned and organized production chain, significantly enhancing production capacity. AS / RS has become a hallmark of enterprise production and management informatization. Telescopic forks are one of the core pieces of equipment in AS / RS, undertaking the critical tasks of cargo handling and storage. Telescopic forks are widely used in warehousing, beverage, packaging, printing, wool and cotton textiles, railways, tobacco, home appliances, automobile manufacturing, steel smelting, chemicals, and construction industries.

[0003] In inverted loading operations, the application scenarios of telescopic forks are constantly expanding. However, the problem of grease splattering during operation is becoming increasingly prominent, becoming a bottleneck restricting the efficient and high-quality development of logistics and warehousing. During transmission, telescopic forks require grease lubrication to ensure smooth operation. However, currently available inverted forks inevitably cause grease splattering when lifting tooling-type goods due to the fork's inherent transmission characteristics. Once this splattered grease falls onto the goods, it contaminates them, affecting their quality and appearance, and may even lead to damage or spoilage, causing economic losses to businesses.

[0004] Therefore, there is an urgent need to develop an effective solution to prevent grease from splashing onto goods inside the telescopic fork and to meet the usage requirements of telescopic forks in inverted storage environments. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a telescopic fork with an anti-splash oil device for use in inverted loading conditions.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A telescopic fork with an anti-splash device for use in inverted loading conditions includes an upper fork, a middle fork, and a lower fork arranged in pairs. The upper fork, the middle fork, and the lower fork are sequentially movably connected and arranged along the same axis. The upper fork can extend and retract horizontally relative to the middle fork, and the middle fork can extend and retract horizontally relative to the lower fork. A drive assembly and an anti-splash assembly are mounted on the lower fork, and the drive assembly is kinetically connected to the upper fork, the middle fork, and the lower fork.

[0008] The splash-proof assembly includes an oil collection cap and a guide. The oil collection cap covers both sides of the lower fork, middle fork, and upper fork from bottom to top. One end of the oil collection cap is installed on the end of the lower fork away from the middle fork, and the other end is installed on the side of the upper fork. The oil collection cap has a flexible and foldable structure, which extends and retracts synchronously along the extension and retraction directions of the upper fork and middle fork, and protects the sides of the upper fork, middle fork, and lower fork. A fixed baffle is installed at the fixed end of the oil collection cap located at the end of the lower fork, and the edge of the fixed baffle is sealed to the edge of the oil collection cap. A movable baffle is installed at the movable end of the oil collection cap located on the side of the upper fork, and the movable baffle is dynamically sealed to the side of the upper fork.

[0009] The guide is installed on its side along the length of the lower fork, and the guide is used in conjunction with the oil collection cap.

[0010] Furthermore, the oil collection cap has a U-shaped accordion-style pleated structure.

[0011] Furthermore, the bottom of the oil collection cover is provided with an oil collection groove, the lowest point of the oil collection groove is provided with an oil drain port, and a removable sealing plug is installed at the oil drain port.

[0012] Furthermore, the movable baffle is connected to the moving edge of the oil collection cover via a hinge shaft; the edge of the movable baffle is provided with a flexible sealing lip, which is interference-fitted with the side of the upper fork.

[0013] Furthermore, the guide includes a guide rail and a sliding block, the sliding block being fixedly connected to the oil collection cap and capable of sliding along the guide rail.

[0014] Furthermore, the oil collection cap is made of stainless steel or high-strength engineering plastic, and its inner wall is provided with an anti-stick coating.

[0015] Furthermore, both the fixed baffle and the movable baffle are made of elastic rubber.

[0016] Furthermore, the drive assembly includes a drive motor and a reducer. The output shaft of the drive motor is connected to the input shaft of the reducer. The output shaft of the reducer is connected to a chain drive mechanism via a sprocket. The chain drive mechanism is connected to the upper fork and the middle fork respectively, and is used to drive the extension and retraction of the upper fork and the middle fork.

[0017] Furthermore, a sealing strip is provided between the edge of the fixed baffle and the end of the lower fork.

[0018] Compared with existing technologies, the beneficial effects of this invention are as follows: During the operation of the telescopic fork, the oil collection cap can extend and retract under the support and guidance of the guide component, providing full-size coverage of the fork body. This closely conforms to the movement of the telescopic fork, greatly reducing the possibility of grease splashing onto the goods, effectively protecting the goods from grease contamination, and improving the quality of goods storage. Simultaneously, the use of materials with a large extension ratio, high wear resistance, and high strength makes it more wear-resistant and durable during frequent extension and retraction, significantly extending the service life of the entire anti-splash device and even the telescopic fork.

[0024] The technical solution of this utility model will now be clearly and completely described through specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] See appendix Figure 1 and attached Figure 2 As shown, this application discloses a telescopic fork with an anti-splash device for inverted loading operations, comprising an upper fork 1, a middle fork 2, and a lower fork 3 arranged in pairs. The upper fork 1, middle fork 2, and lower fork 3 are sequentially movably connected and arranged along the same axis. The upper fork 1 can extend and retract horizontally relative to the middle fork 2, and the middle fork 2 can extend and retract horizontally relative to the lower fork 3. The upper fork 1, middle fork 2, and lower fork 3 are used to meet the needs of cargo handling. A drive assembly 4 and an anti-splash device 5 are mounted on the lower fork 3. The drive assembly 4 is kinetically connected to the upper fork 1, middle fork 2, and lower fork 3, providing power for the extension and retraction of the fork body. The anti-splash device 5 prevents grease from splashing onto the cargo during fork operation.

[0026] The anti-splash oil assembly 5 includes an oil collection cap 51 and a guide 52. The oil collection cap 51 is a flexible and foldable structure. Preferably, the oil collection cap 51 is a U-shaped accordion-style pleated structure, made of stainless steel or high-strength engineering plastic, and has a Teflon anti-stick coating on the inner wall with a coating thickness of 20-50μm. The oil collection cover 51 covers both sides of the lower fork 3, middle fork 2, and upper fork 1 from bottom to top, starting from the bottom of the lower fork 3. The two ends of the oil collection cover 51 along its length are a fixed end and a movable end, respectively. The fixed end of the oil collection cover 51 is installed at the end of the lower fork 3 furthest from the middle fork 2 to ensure stability during fork movement. The movable end is installed on both sides of the upper fork 1 and moves with the extension and retraction of the upper fork 1. The oil collection cover 51 can synchronously extend and retract along the extension and retraction directions of the upper fork 1 and middle fork 2, always maintaining protection for the sides of the upper fork 1, middle fork 2, and lower fork 3. Whether the fork extends to pick up goods or retracts to return to its original position, the oil collection cover 51 can tightly fit the sides of the fork, forming a continuous, gapless protective barrier, effectively preventing grease from splashing outwards. Preferably, the bottom of the oil collection cover 51 has an oil collection groove, and the lowest point of the oil collection groove has an oil drain port. A removable sealing plug is installed at the oil drain port to collect and drain grease splashed during fork operation, preventing grease contamination of goods. During operation, the fork body extends and retracts, causing the oil collection cover 51 to move synchronously. The unfolded or retracted pleated structure always fits tightly against the side of the fork body, forming a continuous protective barrier. When splashed grease comes into contact with the Teflon anti-stick coating on the inner wall of the oil collection cover 51, due to the low adhesion characteristics of the coating, the grease is difficult to adhere and slides down the inner wall of the oil collection cover 51 into the oil collection tank under the action of gravity. When it is necessary to clean the grease, the sealing plug of the oil drain port can be opened to drain the grease.

[0027] A fixed baffle 53 is installed at the fixed end of the oil collection cap 51 located at the end of the lower fork 3. The size of the fixed baffle 53 is adapted to the size of the end of the lower fork 3. The edge of the fixed baffle 53 is sealed to the edge of the oil collection cap 51. Preferably, the fixed baffle 53 is made of elastic rubber or silicone. A sealing strip is provided between its edge and the end of the lower fork 3 to prevent grease from leaking from the end of the lower fork 3. The height of the fixed baffle 53 is not less than the height of the lower fork 3. Preferably, the edge of the fixed baffle 53 is folded upward to form an oil-blocking edge, further enhancing the blocking effect on grease. When grease splashes to the end of the lower fork 3, the fixed baffle 53 first acts as a blockage. The sealing strip ensures the seal between the fixed baffle 53 and the end of the lower fork 3, preventing grease from leaking from the gaps. The oil-blocking edge further prevents grease from overflowing from the edge of the fixed baffle 53, limiting the grease to a certain range and ensuring that the grease does not contaminate the goods.

[0028] A movable baffle 54 is installed on the movable end of the oil collection cap 51 located on the side of the upper fork 1. The movable baffle 54 is made of elastic rubber and is dynamically sealed to the side of the upper fork 1. The movable baffle 54, in conjunction with the pleated structure of the oil collection cap 51, forms a dynamic seal on the upper end of the fork body, effectively preventing grease from splashing from the gap at the movable end. Preferably, the movable baffle 54 is connected to the edge of the movable end of the oil collection cap 51 via a hinge shaft. The edge of the movable baffle 54 is provided with a flexible sealing lip, which is press-fitted to the side of the upper fork 1. When the fork body extends or retracts, the movable baffle 54 moves synchronously with the upper fork 1. Through the hinge shaft, it adjusts its position and angle, ensuring that the flexible sealing lip is always tightly fitted to the side of the upper fork 1, effectively filling the gap between the oil collection cap 51 and the upper fork 1, and preventing grease from leaking from the end of the upper fork 1. During the extension of the fork, the upper fork 1 gradually extends, and the hinge shaft of the movable baffle 54 allows the movable baffle 54 to rotate flexibly. The flexible sealing lip is always in close contact with the side of the upper fork 1 to prevent grease leakage. When the fork retracts, the movable baffle 54 can also adaptively adjust its position to maintain a good sealing effect.

[0029] Guide components 52 are installed on both sides of the lower fork 3. Preferably, the guide component 52 includes a guide rail and a sliding block. The guide rail is a C-shaped channel steel, fixed to the outside of the lower fork 3. The sliding block is a nylon slider embedded in the C-shaped channel steel, fixedly connected to the oil collection cap 51, and can slide along the guide rail. The guide component 52 provides support and guidance for the extension and retraction movement of the oil collection cap 51, ensuring that the oil collection cap 51 maintains a stable movement trajectory during the extension and retraction of the fork body, avoiding deviation or jamming, and ensuring the anti-splashing effect. When the fork body moves, the oil collection cap 51 slides on the guide rail through the sliding block. The structure of the C-shaped channel steel restricts the lateral displacement of the sliding block, so that the oil collection cap 51 can only extend and retract along the direction of the guide rail, thereby ensuring that the oil collection cap 51 always maintains a proper positional relationship with the side of the fork body, effectively preventing grease splashing.

[0030] The drive assembly 4 includes a drive motor and a reducer. The output shaft of the drive motor is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to a chain drive mechanism via a sprocket. The chain drive mechanism is connected to the upper fork 1 and the middle fork 2 respectively, and is used to drive the telescopic movement of the upper fork 1 and the middle fork 2. Preferably, the chain drive mechanism includes a drive sprocket fixed to the end of the lower fork 3, a driven sprocket fixed to the end of the middle fork, and a drive chain surrounding the drive sprocket and the driven sprocket. The drive sprocket is connected to the output end of the drive assembly 4, and one end of the drive chain is fixed to the upper fork, and the other end is fixed to the lower fork 3. This achieves efficient and precise movement of the telescopic fork under inverted loading conditions. At the same time, the tensioning device and the guiding structure ensure transmission reliability. While meeting the requirements for oil splash prevention, it also takes into account space utilization and motion performance, making it suitable for inverted loading equipment in automated warehousing, logistics and other fields.
