Description
Technical Field
[0001] This utility model belongs to the technical field of counterbalance forklift structure, specifically relating to a counterbalance forklift structure powered by methanol. Background Technology
[0002] In the field of modern industrial warehousing and logistics, forklifts, as important industrial handling vehicles, are widely used in the transportation and loading and unloading of large objects, playing a key role in improving warehousing and logistics efficiency. Currently, according to the power source, forklifts are mainly divided into two categories: internal combustion engine forklifts and electric forklifts. Electric forklifts are further subdivided into pure battery forklifts, hydrogen fuel cell forklifts, and other types.
[0003] With increasingly stringent environmental protection requirements, electric forklifts are gradually becoming a market trend due to their advantages such as low pollution and low noise. However, existing electric forklifts have certain limitations in terms of power supply methods. Pure battery forklifts have problems such as limited range and long charging time. Although hydrogen fuel cell forklifts have advantages in range and refueling time, the storage and transportation of hydrogen pose high safety risks and costs.
[0004] Methanol, as a clean, efficient, and widely available energy source, could provide a new solution for powering forklifts if applied to their power systems. However, in existing technologies, the compact overall design of forklifts and extremely limited space make it difficult to rationally arrange the power, electronic control, and hydraulic systems on forklifts. This not only limits the application of methanol fuel in forklifts but also restricts further improvements in forklift performance. Therefore, there is an urgent need to develop a counterbalanced forklift structure powered by methanol to solve the technical problem of the inconvenience of arranging methanol fuel-powered systems on forklifts. Utility Model Content

[0006] A counterweight is installed above the steering wheel assembly. An engine module is installed between the hydraulic oil tank and the methanol oil tank. The engine module is connected to an ignition module and a transmission module. The steering wheel assembly is connected to the transmission module via a steering axle. The drive wheel assembly is connected to the transmission module via a drive axle. An electrical module and a hydraulic station are installed below the counterweight.

[0007] In one specific embodiment, in the above-mentioned counterbalance forklift structure powered by methanol, a cab is provided above the frame. The cab includes a support frame provided above the frame, a top guard provided on the top of the support frame, and a driver's seat provided between the top guard and the frame.

[0018] like Figure 1 , Figure 2 As shown, this utility model discloses a counterbalanced forklift structure powered by methanol, including a frame 1, a drive wheel assembly 3 located at one end of the frame 1, a steering wheel assembly 4 located at the other end of the frame 1, a hydraulic oil tank 2 located on one side of the frame 1, and a methanol oil tank 5 located on the other side of the frame 1. The frame 1 serves as the basic support structure of the forklift, providing a mounting carrier for other components. The hydraulic oil tank 2 stores the hydraulic oil required by the hydraulic system, and the methanol oil tank 5 provides fuel for the engine module 8. A counterweight 9 is installed above the steering wheel assembly 4 to balance the center of gravity of the forklift when transporting goods, ensuring the stability of the forklift. The engine module 8 is located between the hydraulic oil tank 2 and the methanol oil tank 5, and the engine module 8 provides power to the forklift. The core components are: engine module 8 connected to ignition module 51 and transmission module 52; ignition module 51 precisely controls the combustion and ignition process of methanol to ensure stable engine operation; steering wheel assembly 4 connected to transmission module 52 via steering axle 41 to achieve steering operation; drive wheel assembly 3 connected to transmission module 52 via drive axle 31 to obtain power for the forklift's forward and backward movement; electrical module 7 and hydraulic station 21 are located below counterweight 9; electrical module 7 is responsible for the control and management of the forklift's electrical system, such as the operation of lights, instrument panel, and electronic control components; hydraulic station 21 is connected to hydraulic oil tank 2; transport device 11 is located above drive wheel assembly 3; and engine module 8 is connected to methanol oil tank 5.

At the same time, the hydraulic station 21 provides power to the hydraulic system under the control of the electrical module 7, driving the tilting cylinder and other hydraulic devices to work, so as to realize the forklift's cargo handling and loading / unloading functions.
[0024] In summary, compared with the prior art, the methanol-powered counterbalanced forklift structure of this utility model has the following advantages and beneficial effects:
[0025] This device optimizes the layout of forklift components, placing the engine module 8 between the hydraulic oil tank 2 and the methanol oil tank 5, and the electrical module 7 and hydraulic station 21 below the counterweight 9. This effectively solves the layout problem of methanol fuel-electric systems, making full use of limited space. Furthermore, since methanol is a clean and efficient energy source, compared with traditional electric forklift power supply methods, it avoids the problems of short range and slow charging of pure battery forklifts, as well as the high risks and high costs of storage and transportation of hydrogen fuel cell forklifts. It reduces environmental pollution, meets environmental protection requirements, and improves the forklift's range and working efficiency, ensuring the forklift's operational stability and maneuverability, thus possessing excellent practicality.
