Description

Technical Field

[0001] This utility model relates to the field of forklift cooling technology, specifically a cooling device for a four-point internal combustion counterbalance forklift. Background Technology

[0002] Four-point internal combustion counterbalance forklifts are widely used in industrial logistics, warehousing, and port operations. Powered by an internal combustion engine, they generate significant heat during prolonged, high-intensity operation, affecting the engine, transmission components, and hydraulic systems. Failure to cool them effectively can negatively impact performance and efficiency, leading to unstable power output, frequent hydraulic system malfunctions, shortened lifespan of critical components, increased maintenance costs, and even safety hazards due to overheating. Traditional four-point internal combustion counterbalance forklifts use simple bellows for cooling, requiring fixed installation and offering limited cooling coverage. They lack directional flexibility and are not easily adjustable. Furthermore, the absence of a dust cover on the bellows surface allows dust to accumulate, causing internal contamination and requiring regular cleaning, thus impacting efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a cooling device for a four-point internal combustion counterbalance forklift, which has advantages such as dust prevention and solves the problems mentioned in the background technology.

[0005] Side plates are installed on both sides of the front wall of the air inlet hood. A groove is provided in the middle of the inner wall of each side plate. A dustproof cloth is slidably installed on the inner side of each side plate. Two springs are provided in the winding box. The lower end of each spring is connected to the lower end of the dustproof cloth.

[0006] As a further improvement of this utility model: two electromagnetic locks are provided at the front of the bottom of the air inlet hood, and two iron plates are installed at the bottom of the dustproof cloth. The iron plates are all set in corresponding positions with the electromagnetic locks. The iron plates at the bottom of the dustproof cloth are attracted to the electromagnetic locks to fix the dustproof cloth.

[0007] As a further improvement of this utility model, the bellows is made of aluminum alloy, which reduces the weight of the bellows.

[0008] As a further improvement of this utility model, the dustproof cloth is made of nylon material, which has wear resistance and chemical corrosion resistance, thereby improving the service life of the dustproof cloth.

[0009] As a further improvement of this utility model: multiple louvers are installed inside the air inlet hood, and the louvers are rotatably connected to the air inlet hood. The louvers can rotate inside the air inlet hood, thereby controlling the amount of air intake.

[0010] As a further embodiment of this utility model: a second drive motor is installed inside the second motor housing. An L-shaped plate is mounted on the front end of the second drive motor via a motor shaft. A first motor housing is installed at the lower end of the L-shaped plate. A first drive motor is installed inside the first motor housing. A mounting rod is mounted on the lower end of the first drive motor via a motor shaft. The mounting rod is bolted to the air box via four locking bolts. By starting the first and second drive motors, the position of the air box can be adjusted, thereby enabling cooling operations at different locations with high flexibility.

[0011] As a further improvement of this utility model: two mounting brackets are installed on the right side wall of the second motor box. Each mounting bracket is provided with multiple threaded holes, which are used to fix the mounting brackets, thereby improving the stability.
