Description

Technical Field

[0001] This utility model relates to the field of telescopic fork transportation, specifically to a telescopic fork lifting device. Background Technology

[0002] With the rapid development and intelligent upgrading of the logistics and warehousing industry, the types of goods are becoming increasingly complex and diverse, placing higher demands on the application of telescopic forks in automated warehouses, cargo handling, and storage scenarios. As a core component of logistics equipment, telescopic forks are increasingly diverse in models due to differences in cargo types, exhibiting characteristics such as a large number of forks and significant weight.

[0003] Currently, there is a lack of specialized lifting tools for telescopic forks of different sizes and weights, and traditional lifting methods have the following drawbacks:

[0004] 1. Insufficient safety: Conventional hoisting methods cannot ensure uniform load distribution, which can easily cause the telescopic fork to slip or tilt during hoisting, resulting in equipment damage and safety hazards;

[0005] 2. Poor versatility: Different models of telescopic forks have different sizes and specifications, which traditional tools cannot flexibly adapt to, requiring frequent changes of lifting equipment and reducing work efficiency;

[0006] 3. Complex operation: It is difficult to manually adjust the hoisting position, the installation accuracy is low, and it is time-consuming and labor-intensive, making it difficult to meet the needs of modern logistics for high efficiency and automation.

[0007] Therefore, there is an urgent need to design a safe, reliable, adaptable and easy-to-operate telescopic fork lifting device to solve the problems of uneven load distribution, insufficient versatility and low installation efficiency in the existing technology, and promote the automation upgrade of the logistics and warehousing industry. Utility Model Content

[0008] In view of this, the purpose of this utility model is to provide a telescopic fork lifting device.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] A telescopic fork lifting device includes a lifting beam for engaging the telescopic fork body. A fixing assembly is installed on the lifting beam. The fixing assembly includes a first fixing plate, a second fixing plate, a third fixing plate, and a fourth fixing plate. The first fixing plate, the second fixing plate, the third fixing plate, and the fourth fixing plate are located on the same side of the lifting beam. The first fixing plate and the second fixing plate are symmetrically installed at both ends of the lifting beam along its length. The third fixing plate is symmetrically installed near the end of the lifting beam along its length. The third fixing plate is located close to the first fixing plate, and the fourth fixing plate is located close to the second fixing plate.

[0011] The spacing between the first fixing plate and the third fixing plate, and the spacing between the second fixing plate and the fourth fixing plate, are all adapted to the dimensions of the corresponding snap-fit ​​parts of the telescopic fork body.

[0012] Furthermore, the first fixing plate, the second fixing plate, the third fixing plate, and the fourth fixing plate are all L-shaped fixing plates. Each fixing plate includes a bottom plate that fits against the hoisting beam and a vertical plate that is perpendicular to the bottom plate. The vertical plate is used to abut and limit the movement of the telescopic fork body.

[0013] Furthermore, the bottom plate and the vertical plate of the first fixing plate, the second fixing plate, the third fixing plate and the fourth fixing plate are all provided with multiple bolt holes.

[0014] Furthermore, the hoisting beam is an adjustable-length nested structure, including an inner beam and an outer beam that slide and nest together; multiple sets of adjustment holes are provided at corresponding positions on the inner beam and the outer beam, with each set of adjustment holes distributed at intervals along the length of the hoisting beam, and the relative positions of the inner beam and the outer beam are fixed by bolts passing through the corresponding adjustment holes.

[0015] Furthermore, the top of the lifting beam is provided with at least two lifting lugs, each lug including a base plate fixedly connected to the lifting beam and a lifting ring vertically disposed on the base plate.

[0016] Furthermore, the first fixing plate, the second fixing plate, the third fixing plate, and the fourth fixing plate are all detachably connected to the lifting beam and to the telescopic fork body via bolts.

[0017] Furthermore, the hoisting beam is made of high-strength alloy steel and has an anti-corrosion coating on its surface.

[0018] Furthermore, the first fixing plate, the second fixing plate, the third fixing plate, and the fourth fixing plate are all made of aluminum alloy.

[0019] Compared with existing technologies, the advantages of this utility model are as follows: By setting four fixing plates that adapt to the size of the telescopic fork body, the telescopic fork can be firmly fixed to the lifting beam, effectively preventing the telescopic fork from shaking and shifting during the lifting process, thus improving the safety and stability of the lifting process. The adjustable length design of the lifting beam allows it to adapt to telescopic forks of different sizes, expanding the applicability of the lifting device and improving the versatility and practicality of the equipment. The L-shaped fixing plate, multiple bolt holes, and the design of the lifting beam made of high-strength alloy steel and the fixing plate made of aluminum alloy further enhance the fixing effect and overall performance of the device, while taking into account the weight and corrosion resistance of the device, thus possessing high economic and practical value.

[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 As shown, this application discloses a telescopic fork lifting device, including a lifting beam 1 for engaging the telescopic fork body, with fixing components installed on the lifting beam 1. The lifting beam 1, as the core load-bearing component of the entire device, is made of high-strength alloy steel. Its rectangular cross-section design ensures structural strength while effectively dispersing stress during lifting. Preferably, the lifting beam 1 is an adjustable-length structure, composed of nested inner and outer beams. Multiple sets of adjustment holes are correspondingly provided on the inner and outer beams, and these adjustment holes are linearly distributed with precisely designed spacing. In actual use, the operator can pull out or push the inner beam into the outer beam within a certain range according to the specifications of the telescopic fork. After adjusting to a suitable length, bolts are passed through the corresponding adjustment holes and tightened with nuts to fix the relative position of the inner and outer beams, thereby achieving length adjustment of the lifting beam 1 to accommodate the lifting needs of telescopic forks of different sizes.

[0026] The fixing assembly consists of a first fixing plate 2, a second fixing plate 3, a third fixing plate 4, and a fourth fixing plate 5. Along the length of the lifting beam 1, the first fixing plate 2 and the second fixing plate 3 are symmetrically installed at both ends, while the third fixing plate 4 and the fourth fixing plate 5 are symmetrically installed near the ends. The third fixing plate 4 is positioned close to the first fixing plate 2, and the fourth fixing plate 5 is positioned close to the second fixing plate 3. The spacing between the first fixing plate 2 and the third fixing plate 4, and the spacing between the second fixing plate 3 and the fourth fixing plate 5, are adapted to the dimensions of the corresponding engaging parts of the telescopic fork, forming two sets of limiting intervals to ensure no shaking after the fork is engaged. Preferably, the first fixing plate 2, the second fixing plate 3, the third fixing plate 4, and the fourth fixing plate 5 are all detachably connected to the lifting beam 1, allowing their spacing to be adjusted according to the dimensions of the corresponding engaging parts of the telescopic fork. Preferably, to better adapt to the structure of the telescopic fork, the first fixing plate 2, the second fixing plate 3, the third fixing plate 4, and the fourth fixing plate 5 are all L-shaped fixing plates. Each fixing plate includes a base plate that fits against the lifting beam 1 and a vertical plate perpendicular to the base plate. The vertical plate is used to abut and limit the movement against the side of the telescopic fork body. Multiple symmetrically distributed L-shaped fixing plates are bolted to the telescopic fork body, greatly improving the stability and reliability of the telescopic fork during lifting and effectively avoiding problems such as swaying and displacement. Simultaneously, each fixing plate has multiple bolt holes, through which bolts can be passed to firmly fix the fixing plate to the telescopic fork, achieving a detachable and stable connection. For ease of lifting operation, the top of the lifting beam 1 is equipped with at least two lifting lugs. Each lifting lug includes a base plate fixedly connected to the lifting beam and a lifting ring vertically set on the base plate, which allows for convenient connection to the lifting equipment. In terms of material selection, the lifting beam 1 is made of high-strength alloy steel to ensure sufficient strength and rigidity to withstand the weight of the telescopic fork and various stresses during the lifting process. The first fixing plate 2, the second fixing plate 3, the third fixing plate 4, and the fourth fixing plate 5 are made of aluminum alloy. Aluminum alloy has the advantages of being lightweight and corrosion resistant. While ensuring the fixing effect, it can reduce the overall weight of the hoisting device, making it easier to operate and transport.

[0027] Preferably, each fixing plate in this embodiment also integrates an elastic buffer bushing, which can play a buffering and shock-absorbing role during the fixing of the telescopic fork, avoiding damage to the surface of the telescopic fork caused by rigid contact.

[0028] In use, the telescopic fork is placed below the lifting beam 1, aligning the fork's locking part with the limiting range of the two sets of fixing plates. The vertical plates of the fixing plates are fixed to the sides of the fork with bolts, and the bottom plate is fixed to the lifting beam, forming a rigid connection. The extension of the inner beam of the lifting beam 1 is adjusted according to the fork length, and bolts are used to fix the adjustment holes. The lifting lugs are connected to the lifting equipment, and lifting is performed after confirming that all components are securely installed. The two sets of fixing plates can distribute the load on the fork, avoiding concentrated force at a single point. The L-shaped vertical plate restricts the lateral displacement of the fork, and the bottom plate restricts the vertical displacement, ensuring no shaking during the lifting process.

[0029] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
