Description

Technical Field

[0001] This utility model relates to the field of forklift parts technology, specifically an impact-resistant forklift cab. Background Technology

[0002] Forklifts are various wheeled handling vehicles used for loading, unloading, stacking, and short-distance transportation of palletized goods. Technical parameters such as rated lifting capacity, load center distance, and mast tilt angle indicate the structural characteristics and working performance of forklifts. They are usually classified into internal combustion forklifts and electric forklifts.

[0003] Forklift cabs typically feature a closed roof design to prevent drivers from being injured by falling loads when they tip over. However, since the metal roof panel and cab frame are often welded together as a single unit, the cab frame can be significantly deformed after impact. Furthermore, damaged metal roof panels are difficult to replace, which needs improvement. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 3 In this embodiment of the present invention, an impact-resistant forklift cab includes a cab body 1, which is composed of a welded and fixed frame structure and a metal panel. Doors 2 are installed on both outer walls of the cab body 1, and side windows 3 are installed on the doors 2. A windshield 4 is installed on the front wall of the cab body 1. A top cover 5 is connected to the top of the cab body 1 via multiple buffer mechanisms. The top of the cab body 1 is located inside the top cover 5. The buffer mechanism includes a damping telescopic assembly and a spring 12. The bottom end of the damping telescopic assembly is welded and fixed to the top of the cab body 1, and the top end of the damping telescopic assembly is detachably connected to the top cover 5 via bolts 14. The spring 12 is sleeved on the damping telescopic assembly, and the damping telescopic assembly is filled with damping oil.

[0019] By adopting the above-mentioned solution, this utility model utilizes the damping telescopic component and the spring 12. When the top cover 5 is subjected to a severe collision, the spring 12 and the damping telescopic component will contract due to the force to absorb the impact of the collision, thereby effectively reducing the probability of damage to the cab. Furthermore, when the top cover 5 is damaged by a collision, the top cover 5 can be disassembled and replaced simply by removing the bolts 14 that connect the damping telescopic component and the top cover 5. The operation is simple and convenient.

[0020] Specific combination Figure 3 In one embodiment of this utility model, the damping telescopic assembly includes a sleeve 7, with a connecting seat 6 fixedly and sealed to the bottom end of the sleeve 7. The connecting seat 6 is welded and fixed to the top of the cab body 1. A sliding rod 8 is slidably and sealed through the top end of the sleeve 7. The top end of the sliding rod 8 is detachably connected to the top cover 5 by bolts 14. A piston 9 is fixedly connected to one end of the sliding rod 8 inside the sleeve 7. Multiple through holes 10 are provided through the end face of the piston 9. The damping oil is located inside the sleeve 7. The sliding rod 8 and the sleeve 7 are located inside corresponding springs 12. The bottom end of the spring 12 abuts against the top of the connecting seat 6 and the top of the top cover 5.

[0021] When the top cover 5 is impacted and pushes the slide bar 8 to move into the sleeve 7, it will push the piston 9 to move downward in the sleeve 7, so that the damping oil below the piston 9 flows through the through hole 10 to the top of the piston 9, thereby using the friction and shear force of the damping oil to absorb the impact.

[0022] Specific combination Figure 3 In one embodiment of this utility model, a square rod 19 is integrally machined at the top of the slide rod 8, and a threaded hole 13 adapted to the bolt 14 is opened at the top of the square rod 19. A square hole 17 is opened at the top of the top cover 5 corresponding to each square rod 19, and the square hole 17 is adapted to the square rod 19.

[0023] By using the square hole 17 and the square rod 19 to fit together, the square rod 19 and the sliding rod 8 can be prevented from rotating together with the bolt 14 during the installation of the bolt 14 in the threaded hole 13.

[0024] Specific combination Figure 3 In one embodiment of the present invention, the outer wall of the bolt 14 above the top cover 5 is fitted with a washer 15 and a rubber ring 16, and the rubber ring 16 is located between the washer 15 and the top cover 5.

[0025] Specific combination Figure 3 In one embodiment of this utility model, a first sealing ring 11 is embedded in the outer wall of the piston 9. The outer wall of the first sealing ring 11 fits against the inner wall of the sleeve 7 to ensure the sealing between the outer wall of the piston 9 and the inner wall of the sleeve 7, so that the damping oil can only pass through the through hole 10. A second sealing ring 18 is embedded in the top opening of the sleeve 7. The inner wall of the second sealing ring 18 fits against the outer wall of the slide rod 8 to ensure the sealing between the slide rod 8 and the sleeve 7.

[0026] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
