Description

Technical Field

[0001] The utility model relates to the technical field of chassis, in particular to a chassis frame of a truck crane. Background Art

[0002] The chassis frame of a truck crane is the core component of the crane system, which needs to have sufficient strength and stability to support the weight of the crane and the stress generated during operation. Traditional chassis frames of truck cranes usually adopt simple structural designs, which may not meet the requirements of modern engineering for stability, safety, and durability. With the development of technology, higher requirements are put forward for the design of chassis frames of truck cranes, including better stability, stronger load-bearing capacity, longer service life, and higher operating flexibility.

[0003] A Chinese patent discloses a vehicle chassis and its subframe (Publication No.: CN 208827938U), which includes an upper subframe plate and a lower subframe plate. It is characterized in that it further includes a reinforcing bracket and a sleeve located between the upper subframe plate and the lower subframe plate. The reinforcing bracket includes an upper cover plate and a support plate located below the upper cover plate and extending in the up and down direction. The upper end face of the sleeve is welded to the upper cover plate, the lower end face of the sleeve is welded to the lower subframe plate, the bottom end of the support plate is welded to the lower subframe plate, and the upper cover plate is welded to the upper subframe plate. However, this chassis frame has a simple structure and cannot meet the requirements of modern engineering for stability, safety, and durability. Therefore, a chassis frame of a truck crane is needed.

The main crossbeam and the reinforcing longitudinal beam are made of high-strength alloy steel, which has excellent bending and torsion resistance and can withstand long-term high-intensity work requirements. The heat dissipation slot holes on the side plate help improve the efficiency of the radiator, reducing the engine temperature by increasing air circulation, thus protecting the engine from overheating damage. The design of the boom hinge seat enables the boom to operate at different angles, improving the flexibility and operation range of the truck crane. The mounting holes on the turntable connection port are arranged in an equally spaced array form, simplifying the installation process of the turntable and making maintenance more convenient.

At the center of the top of the main cross beam 4, there is a turntable connection port, and there are mounting holes on the turntable connection port. The number of the mounting holes is 20 - 30 and they are arranged in an equidistant array form. These holes are arranged in an equidistant array form for fixedly connecting the turntable. On both sides of the main cross beam 4, there are side plates. Between the inner walls of the main cross beam 4, there is a reinforcing longitudinal beam 9 for increasing the overall strength of the frame. On one side of the reinforcing longitudinal beam 9, there is a radiator mounting seat 8 for mounting a radiator to optimize the engine cooling efficiency.

[0021] In this embodiment, the number of the leg control valve mounting seats 7 is 2 groups and they are arranged correspondingly.

At the edge ports of the connecting square beams 6, there are telescopic leg mounting positions 5 for mounting telescopic legs, and these legs can adjust the working height of the truck crane to provide stable support.

[0022] In this embodiment, there are heat dissipation slot holes 11 on the side plates. The number of the heat dissipation slot holes 11 is 8 - 12. The design of the heat dissipation slot holes 11 helps to improve the efficiency of the radiator, reduces the engine temperature by increasing air circulation, and thus protects the engine from overheating damage.

[0023] In this embodiment, there is a counterweight mounting seat 2 at the bottom of the main cross beam 4. On the other side of the counterweight mounting seat 2, there is a hoisting mechanism mounting seat 3. On one side of the counterweight mounting seat 2, there is a connecting extension beam 1.

[0024] In this embodiment, there is a boom hinge seat 10 on one side of the leg control valve mounting seat 7. This hinge seat is used to connect the boom so that it can swing relative to the frame body. This design enables the boom to operate at different angles, improving the flexibility and operating range of the truck crane.

[0025] In this embodiment, the main cross beam 4 and the reinforcing longitudinal beam 9 are both made of high-strength alloy steel, which is a common product on the market and can be directly purchased.

On the outer walls on both sides of the main cross beam 4, there are outrigger control valve mounting seats 7 for installing outrigger control valves to ensure that the crane stands steadily during operation. At the center of the top of the main cross beam 4, there is also a turntable connection port, which is fixed to the turntable through rows of equally spaced mounting holes. The turntable functions like the "head" of the crane and can rotate left and right. Between the inner walls of the main cross beam 4, there is a reinforcing longitudinal beam 9, which increases the overall strength of the vehicle frame. On one side of the reinforcing longitudinal beam 9, there is a radiator mounting seat 8. The radiator sucks in cold air through the heat dissipation slots 11 on the side plate to cool the engine and prevent overheating. The winch structure mounting seat is used to install the winch mechanism, which is responsible for controlling the retraction and extension of the hoisting cable. The counterweight mounting seat 2 increases the stability of the crane during operation by installing counterweights, making the crane stand more firmly on the ground.
