DETAILED DESCRIPTION
[0019] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
[0020] Example
[0021] See also Figure 1-4 , the utility model provides a technical solution: a chassis structure of a heavy-duty material handling vehicle with vibration reduction;
[0022] This project aims to provide a chassis structure for heavy-duty material handling vehicles that is conducive to vibration reduction. Existing heavy-duty material handling vehicles have a fixed overall structure, and the overall vibration reduction effect is poor, which easily affects the transportation of goods.
[0023] Based on the above issues, the components in this case include a chassis body 1 and a vehicle body 2 arranged on top of the chassis. A connecting frame 3 is provided between the top of the chassis body 1 and the bottom of the vehicle body 2. The upper side of the connecting frame 3 is connected to the bottom of the vehicle body 2 by bolts. Both sides of the bottom of the connecting frame 3 are provided with fixing seats 4 connected to the top of the chassis body 1. A support block 5 is embedded in the middle part of the fixing seat 4. A first hydraulic shock absorber 6 is installed on the top of the support block 5. The top of the first hydraulic shock absorber 6 is connected to one side of the bottom of the connecting frame 3.
[0024] Limiting grooves are provided on both sides of the fixing seat 4, and a moving block 7 is slidably connected inside the limiting groove. The top of the moving block 7 is rotatably connected to a transmission rod 8. The upper side of the transmission rod 8 is rotatably connected to the bottom of the connecting frame 3. The inner wall of the limiting groove is connected to a second hydraulic shock absorber 9. One end of the second hydraulic shock absorber 9 is connected to one side of the moving block 7. The lower side of the connecting frame 3 is provided with an auxiliary vibration reduction component connected to the top of the chassis body 1;
[0025] The auxiliary vibration reduction assembly includes a bracket 10 arranged on the lower side of the connecting frame 3. A third hydraulic shock absorber 11 connected to the top of the chassis body 1 is provided on both sides of the bottom of the bracket 10. A connecting cylinder 12 is installed at the bottom of the bracket 10. A lifting cylinder 13 is inserted at the bottom of the connecting cylinder 12. A screw 14 is connected to the inside of the connecting cylinder 12 through a bearing. The bottom of the screw 14 is threadedly connected to the top of the lifting cylinder 13. The bottom of the bracket 10 is connected to a cross bar 15 through a bearing seat. The cross bar 15 is connected to the screw 14 through tapered teeth.
[0026] It should be noted that when the goods are being transported and driven on the ground, the vehicle body 2 receives the vertical downward pressure from the goods and moves downward. At this time, the vehicle body 2 drives the connecting frame 3 to move downward and compresses the first hydraulic shock absorber 6, thereby performing the first vibration reduction. At the same time, the moving frame drives the moving block 7 to slide inside the limiting groove through the transmission rod 8 and compresses the second hydraulic shock absorber 9, thereby completing the second vibration reduction.
[0027] Among them, the support block 5 is used to provide vertical support for the first hydraulic shock absorber 6, and the fixing seat 4 is used to cooperate with the limit groove of the moving block 7 to limit the moving range of the moving block 7;
[0028] As the connecting frame 3 moves downward, the moving block 7 is squeezed by the bracket 10 and the third hydraulic shock absorber 11, thereby achieving the purpose of third vibration reduction, thereby ensuring the stability of the vehicle body 2 and the cargo during transportation, and preventing the cargo and the vehicle body 2 from being damaged by bumps when the road conditions are poor;
[0029] At the same time, the bottom of the bracket 10 is connected to a cross bar 15 through a bearing seat, and the cross bar 15 is connected to the screw 14 through bevel gear meshing. Before use, the operator can rotate the cross bar 15 through the fixed sleeve, thereby cooperating with the two vertically set bevel gears to drive the screw 14 to rotate, and then drive the lifting cylinder 13 to rotate vertically along the connecting cylinder 12, and then the third hydraulic shock absorber 11 can be tightened or loosened, thereby adjusting the shock absorption strength and making the shock absorption efficiency of the third hydraulic shock absorber 11 higher. There are limiting grooves on the outer wall surface of the lifting cylinder 13 and the inner wall of the connecting cylinder 12. The outer wall surface of the lifting cylinder 13 is slidably connected to the limiting groove, which is used to increase the stability of the adjustment process of the lifting cylinder 13;
[0030] A rubber anti-skid pad 17 is provided at the connection between the top of the bracket 10 and the connecting frame 3 to prevent slipping between the bracket 10 and the connecting frame 3. A protective cover 18 is provided on the lower side of the vehicle body 2 to block and protect the lower parts of the vehicle body 2. A sliding groove is provided on the inner wall at the bottom of the limit groove, and the moving block 7 is slidably connected to the sliding groove to increase the stability of the movement of the moving block 7.
[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
