Embodiment Construction
[0016] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0017] Such as Figure 2 ~ Figure 4 , a new type of chassis structure, including an outer frame 1, an inner return-shaped frame 2, a double-piston rod cylinder 3, two piston rods 4, four arc-shaped tie rods 5, four legs 6, and four tires 7. The double-piston rod oil cylinder 3 is connected with the external controller 8, the electrical system 9, and the hydraulic system 10, the inner return frame 2 is sleeved in the middle of the outer frame 1, and the double-piston rod oil cylinder 3 passes through the inner Back-shaped frame 2, one end of the two piston rods 4 is respectively slidably connected in the double-piston rod oil cylinder 3, and the other end is respectively connected to the two arc-shaped pull rods 5; the other ends of the four arc-sh...

The invention discloses a novel chassis structure. The novel chassis structure comprises an outer framework (1), an inner dual-rectangle-shaped framework (2), a dual-piston-rod oil cylinder (3), two piston rods (4), four arc-shaped pull rods (5), four supporting legs (6) and four tires (7), wherein the dual-piston-rod oil cylinder (3) penetrates through the inner dual-rectangle-shaped framework (2); on end of each piston rod (4) is glidingly connected in the dual-piston-rod oil cylinder (3), and the other ends of the piston rods (4) are connected with two of the arc-shaped pull rods (5) respectively; the other ends of the four arc-shaped pull rods (5) are connected with inner sides of tail ends of four corners of the outer framework (1). Synchronous movement of four wheels on a chassis is guaranteed by changing the structure, the safety performance is improved, internal hydraulic parts and mounting procedures are reduced, and labor and material costs are reduced; compared with the width of an originally designed chassis structure, the width of the chassis structure is increased by about 500 mm after extension, the supporting areas of the four tires are further increased, and the safety stability is improved.
Description
technical field [0001] The invention belongs to the field of engineering machinery, in particular to a novel chassis structure. Background technique [0002] At present, in order to save the storage space, the chassis structure of the traditional aerial work platform adopts the extension type, such as figure 1 As shown, it is H-shaped. Before preparing for the operation, the movement of the chassis is as follows: the four tires are respectively stretched outwards by the pressure of the inner oil cylinder of the two outriggers, and the side with the small friction between the tire and the ground is pushed out, and then the tire on the other side is pushed out , until the maximum stroke of the cylinder, that is, the maximum width that the chassis can extend. Such a design causes the whole vehicle to shake when the outriggers are stretched due to the inconsistent stretching speeds of the four tires. Contents of the invention [0003] Purpose of the invention: To design a n...
