Description

Technical Field

[0001] The invention relates to the field of transport vehicles, in particular to a self-propelled transport machine and a chassis thereof. Background Art

[0002] As the name implies, a self-propelled conveyor is a mechanical device that can travel autonomously and transport materials without external traction or pushing. This type of equipment is widely used in agriculture, industry, construction, logistics and other fields to improve transportation efficiency and reduce labor costs. With the continuous development of science and technology, self-propelled conveyors will become more intelligent and automated, providing more efficient and convenient transportation solutions for all walks of life. At the same time, it is also necessary to pay attention to the potential safety hazards and environmental problems that may arise during their use, and strengthen supervision and protective measures.

[0003] The chassis used by current self-propelled transporters is mainly composed of three major parts: the lower part, the slewing platform and the slewing bearing. This mechanism is widely used in current engineering machinery, but for self-propelled transporters, there are several defects: 1. The overall height of the upper platform is too high, which causes the center of gravity of the whole machine to be too high, making it easy to shake violently when walking, which is not conducive to normal driving.

[0004] 2. Since the self-propelled conveyor does not need to rotate during operation, the slewing bearing structure is not used, which increases the manufacturing cost.

[0005] Therefore, it is necessary to improve the current self-propelled transport aircraft. Summary of the invention

[0008] As a preferred solution, the frame includes a lower plate and an upper plate, the upper plate and the lower plate are spaced apart from each other, a plurality of support plates are welded and connected between the upper plate and the lower plate, the aforementioned lower space is formed between the upper plate and the lower plate, and the aforementioned upper space is formed above the upper plate.

[0009] As a preferred solution, a through hole is formed vertically through the middle of the frame, and the hydraulic system includes a hydraulic valve, which is sunken and placed in the through hole.

[0010] As a preferred solution, the electrical system includes a motor, an electric control cabinet and a radiator. The upper plate is provided with a first mounting plate for mounting the motor, a second mounting plate for mounting the electric control cabinet, a third mounting plate for mounting the radiator and a fourth mounting plate for mounting the oil tank. The first mounting plate and the second mounting plate are respectively located on the left and right sides of one end of the upper plate, and the third mounting plate and the fourth mounting plate are respectively located on the left and right sides of the other end of the upper plate.

[0011] A self-propelled transport machine comprises a chassis as claimed in any one of claims 1 to 4, a supporting mechanism and a conveying device; the supporting mechanism is arranged on the chassis, and the conveying device is arranged on the supporting mechanism.

[0012] As a preferred solution, the front and rear sides of the chassis are respectively arranged on the first connecting seat and the second connecting seat, and the supporting mechanism includes a first supporting assembly and a second supporting assembly, the lower end of the first supporting assembly and the lower end of the second supporting assembly are respectively connected and fixed to the first connecting seat and the second connecting seat, and the upper end of the first supporting assembly and the upper end of the second supporting assembly are separated from each other and are both fixedly connected to the conveying device.

[0013] As a preferred solution, the first supporting assembly includes two first supporting rods, multiple first cross rods and a first fixed seat; the first connecting seat is two separately arranged on the left and right, the two first supporting rods are separately arranged on the left and right and extend obliquely upward, the lower ends of the two first supporting rods are respectively fixedly connected to the two first connecting seats, the multiple first cross rods are arranged in parallel with each other at intervals up and down, the two ends of each first cross rod are respectively welded and fixed to the two first supporting rods, the two ends of the first fixed seat are respectively fixedly connected to the upper ends of the two first supporting rods, and the first fixed seat is fixedly connected to the conveying device.

There will be no major shaking when walking, which is more conducive to normal driving. At the same time, the slewing bearing and slewing platform are reduced, and the mounting seat used to install the slewing bearing is also cancelled on the crawler undercarriage, which greatly reduces the manufacturing cost.
