Description

Technical Field

[0001] This utility model relates to the field of lifting and freight equipment technology, specifically to an electric station-operated stacker truck. Background Technology

[0002] A stacker truck is an industrial loading and unloading machinery. It has the functions of moving and lifting goods, and refers to various wheeled handling vehicles used for loading, unloading, stacking, and short-distance transportation of palletized goods. Stackers are characterized by their compact structure, flexible transportation, simple operation, small turning radius, and high explosion-proof safety performance. They are suitable for operations in narrow aisles and confined spaces, making them ideal equipment for palletized loading and unloading in high-bay warehouses and workshops. They are suitable for cargo handling and stacking in factories, workshops, warehouses, stations, docks, and other similar locations.

[0003] Stacker trucks are categorized by their power source into manual hydraulic, internal combustion engine, and electric types. Electric stacker trucks, due to their ease of operation and practicality, have gradually become the mainstream trend. An electric stand-on stacker truck mainly consists of a frame, handle assembly, stand-on pedals, drive assembly, and mast system. The handle assembly controls the drive assembly to move the vehicle, while the forks on the mast system are used to lift, stack, and load / unload goods.

[0004] Existing electric stackers typically have a forklift (also called a fork frame) made of two welded steel plates, with a load capacity of around 2 tons. Loads exceeding 2 tons can easily cause fork deformation. The lifting fork (also called a carrying rack) is usually made of welded steel plates and reinforcing ribs, with a load capacity of around 1.5 tons. Loads exceeding 1.5 tons can also easily cause fork deformation. The insufficient load capacity of existing electric stackers significantly reduces their applicability and makes it difficult to meet the increasingly heavy load requirements of modern stacking. While adding steel plates to the fork structure could increase the stacker's load capacity, it would also correspondingly increase the fork's thickness or height, which would be limiting in most loading, unloading, and stacking applications, making it a less than ideal choice.

[0005] Therefore, it is necessary to design a new fork structure to ensure the load-bearing capacity of the stacker and improve its practicality. Utility Model Content

[0006] To better address the aforementioned issues, this utility model provides an electric stand-operated stacker, which improves the load-bearing capacity of the stacker without increasing the thickness and width of the forks, thus meeting the high requirements for cargo loading, unloading, and stacking.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] An electric stand-operated stacker includes a gantry system comprising traveling forks and lifting forks. The traveling forks are rolled from high-strength profile steel, with a U-shaped cross-section and a groove on the upper side. The lifting forks are forged from high-strength profile steel, forming an L-shape consisting of a base plate and a vertical plate. A connector matching the lifting frame of the gantry system is provided on the rear side of the vertical plate. A protruding connecting block is provided at the front end of the traveling forks, and a set of traveling wheels is provided on the connecting block. The set of traveling wheels includes two traveling wheels that span across both sides of the connecting block via axles. When the lifting forks are not lifted, the base plate of the lifting forks is located within the groove, and the front end extends between the two traveling wheels.

[0009] Optionally, the width of the bottom plate of the lifting fork is not greater than the groove width on the traveling fork, and the length is greater than the length of the groove.

[0010] Optionally, the front end of the traveling fork is provided with two sets of traveling wheels.

[0011] Optionally, the connecting block extends forward from the bottom plate of the groove, and the width of the connecting block is equal to the groove width.

[0012] Optionally, the thickness of the bottom plate of the lifting fork gradually decreases from the protruding groove to the front end.

[0013] Optionally, the gantry system includes two sets of hydraulic cylinders for driving the lifting frame to move vertically up and down.

[0014] The electric station-operated stacker truck of this utility model has at least the following beneficial effects:

[0015] This electric station-operated stacker truck uses high-strength steel profiles to manufacture both the lifting forks and the traveling forks, which increases the load-bearing capacity of the forks. Furthermore, by designing the traveling forks with a grooved shape, the lifting forks and traveling forks can fit tightly together without increasing the overall thickness of the forks. By installing a connecting plate at the front end of the traveling forks to install side-mounted traveling wheels, the vehicle's stability is improved without increasing the fork width or affecting the fit between the lifting forks and traveling forks.

[0016] This electric station-operated stacker has the advantages of simple structure, reliable performance and convenient use. Without increasing the thickness and width of the forks, it improves the load-bearing capacity and can meet the high requirements of cargo loading, unloading and stacking for load weight, making it more practical.

[0023] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the implementations of the base model disclosed below.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] like Figure 1-3As shown, an embodiment of the present invention provides an electric stand-on stacker, including a frame and a mast system 1, a drive assembly 2, a handle assembly 3, and a stand-on foot pedal 4 mounted on the frame. The frame supports various components or structures. The drive assembly 2, located at the rear of the frame, includes a drive motor, a steering motor, main wheels, and a shock absorber, and is used to drive the vehicle. The handle assembly 3, located above the drive assembly, includes a handle, a handle rod, and a handle seat, and is used to control the drive assembly 3 to drive the vehicle's movement and steering, as well as to control the lifting and lowering of the forks in the mast system 1. The stand-on foot pedal 4 is located at the rear of the frame, facilitating user standing. It should be noted that in this embodiment, the frame, drive assembly 2, handle assembly 3, and stand-on foot pedal 4 are not the main innovations of this electric stand-on stacker; their specific structures can be found in existing electric stackers and will not be described further here.

[0026] In this embodiment of the electric stand-operated stacker truck, the gantry system 1 includes components such as a gantry, a lifting frame 5, a hydraulic cylinder, a transmission chain assembly, lifting forks 6, and traveling forks 7. The lifting frame 5 is slidably mounted on the gantry. The hydraulic cylinder is connected to the lifting frame 5 via a transmission chain. The lifting forks 6 are mounted on the lifting frame 5. The lifting frame 5 is driven to rise and fall on the gantry by the hydraulic cylinder, which in turn drives the lifting forks 6 to rise and fall, thereby facilitating the loading, unloading, and stacking of goods by the vehicle. The traveling forks 7 are located at the bottom of the gantry system 1 and are equipped with traveling wheels. Together with the main traveling wheels of the drive assembly (including a steerable drive wheel and two driven wheels), the vehicle can travel stably.

[0027] In the gantry system 1, the lifting fork 6 is rolled from high-strength profile steel and includes two fork rods. Each fork rod consists of a base plate and side plates located on both sides of the base plate. The cross-section of the fork rod is U-shaped, and the upper side has grooves formed by the side plates and the upper surface of the base plate. The lifting fork 6 is forged from high-strength profile steel and includes two L-shaped fork rods composed of a base plate and a vertical plate. The rear side of the vertical plate is provided with a connector for connecting the lifting frame 5 of the gantry system 1. This connector can be two upper and lower snap hooks 9 that match the snap slots on the lifting frame 5.

[0028] The forklift 7 has a protruding connecting block 10 at its front end. The connecting block 10 extends from the front end of the base plate at the groove, and its width is equal to the width of the groove. A set of traveling wheels is mounted on the connecting block 10, comprising two traveling wheels 8 that span both sides of the connecting block 10 via axles. The side plates of the groove are located behind the traveling wheels 8. This two-sided traveling wheel design does not increase the width of the forklift. The traveling wheels 8 are driven wheels, while the main traveling wheels in the drive assembly 2 are driven wheels. The two forklifts shown in the figure each have two sets of traveling wheels at their front ends, ensuring stable support for the frame and stable movement.

[0029] The width of the base plate of the lifting fork 6 is equal to or slightly smaller than the width of the groove on the traveling fork 7, and the length of the base plate of the lifting fork 6 is greater than the length of the groove. When the lifting fork 6 is not lifted, the base plate of the lifting fork 6 is located in the groove and its front end extends out from between the groove and the two traveling wheels 8 of the traveling wheel assembly. The thickness of the base plate of the lifting fork 6 gradually decreases from the point where it extends out of the groove to the front end, facilitating the picking up and unloading of goods.

[0030] The electric stand-operated stacker of this utility model uses high-strength profile steel for the lifting fork 6 and the traveling fork 7, which can improve the load-bearing capacity of the forks. Moreover, the traveling fork 7 is designed with a groove and two-sided traveling wheels, so the lifting fork 6 can fit into the groove without increasing the overall thickness of the fork, thereby improving the load-bearing capacity of the fork without increasing the thickness of the fork.

[0031] According to an exemplary embodiment of this utility model, in practical application scenarios, the frame, drive assembly 2, handle assembly 3, and standing pedal 4 of the electric stand-up stacker can all be made of existing equipment or devices with corresponding functions and specifications. Furthermore, the traveling fork 7, lifting fork 6, and lifting frame 5 of the gantry system 1 can be made of relevant high-strength steel profiles from the prior art, depending on the size, shape, and load-bearing requirements in the actual application.

[0032] Furthermore, other equipment or components can be installed in the stacker, or the actual installation positions of each piece of equipment or component can be adjusted to achieve the actual application or other functions of the stacker. For example, if the stacker has increased fork load capacity, it also needs to be equipped with higher driving force to drive the lifting frame 5 to lift heavier goods. Therefore, two hydraulic cylinders can be installed on both sides of the mast to drive the vertical lifting of the lifting frame 5.

[0033] It should be noted that, depending on the implementation needs, the various components described in the embodiments of this utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of this utility model.

[0034] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
