Description

Technical Field

[0001] The invention relates to the technical field of logistics transportation equipment and its accessories, in particular to a detachable combined forklift lifting tool. Background Art

[0002] With the widespread application of forklifts in construction, glass production and deep processing industries, steel, stone building materials industry, chemical industry, machinery, etc., forklifts are increasingly limited in loading and unloading goods solely by forks. Some goods or products cannot be directly loaded and unloaded using forklift forks. However, when there are no other lifting tools at the loading and unloading site, how can we cleverly use forklifts to provide convenience for people's daily production?

[0003] In the past decades of construction and industrial production, forklifts have been widely used as a common special transportation equipment, such as loading and unloading cement and steel at construction sites. However, it is obviously inconvenient to load and unload fragile goods such as glass and decorative materials. How to effectively use forklifts and reduce investment has always been one of the issues that people are thinking about. How to turn the forklift's forklift into hoisting, thereby improving the utilization rate of the forklift, without changing the original forklift structure, and avoiding the embarrassment of failing the forklift's annual inspection.

[0004] Therefore, a kind of forklift special lifting device with excellent performance, flexibility, and detachable and installable is in urgent need of research. Summary of the invention

[0005] In order to solve the problems of the prior art, the present invention provides a detachable combined forklift lifting tool.

[0006] In order to solve the above technical problems, the present invention is implemented through the following technical solutions: a detachable combined forklift lifting tool, comprising:

[0007] The vertical arm comprises a vertical arm body and a mounting top plate. A fixed mounting plate and a positioning block are arranged on one side of the vertical arm body, which are used to install and suspend the vertical arm in the middle position of the forklift, and are connected and fixed to the fork guide rail of the forklift by two bolts. The vertical arm body is fixedly connected to the mounting top plate, and a first positioning bracket and a second positioning bracket are arranged on the top of the mounting top plate;

[0008] The retractable boom is adjustable and plugged into the inner wall of the first positioning bracket and the second positioning bracket for assembly. The retractable boom includes a boom body and an articulated frame. A connecting ring is provided at one end of the boom body, and a rotatable lifting hook is connected to the other end through the articulated frame.

[0009] The balanced lifting beam comprises a balanced lifting beam body and lifting ears. A plurality of baffles are arranged on both sides of the top of the balanced lifting beam body. The lifting ears are provided with main lifting ear holes and auxiliary lifting ear holes for connecting with the lifting hook.

[0010] Among them, the vertical arm, the telescopic boom and the balancing beam cooperate with each other through a connecting structure to form a detachable spreader, which is convenient for alternating with the forklift forks without damaging the original structure of the forklift.

[0011] In this method, the lifting tool is designed to be detachable, which is convenient for alternating with the forklift fork, without any damage or modification to the original structure of the forklift. The various components are connected by a connection structure (such as bolt connection, plug connection or hinged connection) to achieve rapid disassembly and assembly, which improves work efficiency and flexibility;

[0012] The shape and size of the vertical arm, telescopic boom and balance beam can be adjusted according to the size of the forklift model to ensure compatibility with different models of forklifts. The specifications of the balance beam can be adjusted according to actual needs to adapt to different operating requirements and forklift models, which improves the versatility and practicality of the equipment.

[0013] The main body of the boom adopts a hollow steel pipe structure with sufficient strength and rigidity. The lifting hook set at the front end can bear a load of 5 tons, meeting the needs of most forklift lifting operations. Through the simple connection structure, the operator can easily install and remove the lifting tools without complicated operations or tools. The design of the balanced lifting beam enables the lifting hook to lift and lower the cargo smoothly, reducing the difficulty and risk of operation.

[0014] In some specific embodiments, the specific dimensions of the boom body are 1500 mm in length, 85 mm in width, 160 mm in height, with a wall thickness of 10 mm. It adopts a hollow steel pipe structure, and the lifting hook arranged at the front end can bear a load of 5 tons.

[0015] In some specific implementations, the specifications of the balanced lifting beam can be adjusted within the range of length: 2400mm-6000mm, width: 85mm-100mm, height: 180mm-200mm according to actual needs to adapt to different forklift models and operation requirements.

[0016] In some specific embodiments, the shapes and sizes of the vertical arm, the telescopic boom and the balancing beam can be adjusted according to the size of the forklift model.

[0017] In some specific embodiments, the connection structure includes, but is not limited to, a bolt connection, a plug connection, or a hinge connection to achieve rapid disassembly and assembly between the components.

[0018] The beneficial effects of the present invention are:

[0019] 1. The present invention designs a detachable special lifting device, which realizes the expansion of the forklift from a single fork-lifting function to a lifting function, greatly improving the utilization rate and versatility of the forklift. This design enables the forklift to perform not only traditional fork-lifting operations, but also lifting operations, achieving the goal of "one vehicle for multiple uses";

[0020] 2. Traditionally, in order to carry out lifting operations, enterprises may need to purchase additional lifting equipment or modify the forklift structure, which not only increases the investment cost, but also may damage the original structure and performance of the forklift. However, the lifting device of the present invention is cleverly designed, and the lifting function can be achieved without any modification of the forklift, thereby greatly reducing the additional investment cost of the enterprise;

[0021] 3. The design of the retractable boom enables the spreader to adapt to the lifting needs of cargoes of different sizes and weights. At the same time, the 360-degree rotating lifting hook further improves the flexibility and efficiency of the operation, allowing the cargo to be lifted and moved in any direction. This design not only improves the operating efficiency, but also reduces the difficulty of the operation caused by different sizes or shapes of cargoes;

[0022] 4. The shape and size of the sling of the present invention can be adjusted according to the size of the forklift model, but the internal structure and principle remain unchanged. This design makes the sling widely applicable and can adapt to forklifts of different models and specifications. At the same time, since the sling is simple in design, easy to operate and maintain, it is easy to promote and use in enterprises and industries. BRIEF DESCRIPTION OF THE DRAWINGS
