Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the utility model.
[0022] Please refer to Figures 1 to 5 The utility model provides an improved mine car cab protection structure, including base frame 1 and cab body 7, the front and rear end of cab body 7 all are fixedly welded with a plurality of fixed frame 10, the right side of the front and rear end of base frame 1 all are fixedly installed with mounting beam 6, a plurality of mounting beams 6 are inserted in corresponding fixed frame 10 respectively, a plurality of fixed frame 10 all are provided with perforation 9, and a plurality of perforation 9 all are threadedly connected with fixed bolt 11, the top of base frame 1 is fixedly installed with positioning frame 2, the top of positioning frame 2 and the left side of base frame 1 all are fixedly installed with a plurality of dampers 13, the upper portion of positioning frame 2 is provided with top plate 4, the left side of base frame 1 is provided with protective net 5, the front and rear end of protective net 5 all are fixedly installed with a plurality of connecting plates 12, the output of a plurality of dampers 13 is fixedly installed on corresponding connecting plate 12 and top plate 4 respectively, and the outside of a plurality of dampers 13 all are provided with shock absorbing spring 14.
[0023] The left end of the base frame 1 and the top end of the positioning frame 2 are fixedly provided with two rubber seats 8 between a plurality of dampers 13, and the top plate 4 and the protective net 5 can be secondarily buffered through the two rubber seats 8. An opening 16 is arranged between the two rubber seats 8 in the base frame 1, and the opening 16 is reserved to facilitate the driver to view the surrounding situation through the front windshield of the cab body 7. One end of a plurality of shock absorber springs 14 is fixedly arranged on the base frame 1 and the positioning frame 2, respectively, and the other end of the plurality of shock absorber springs 14 is fixedly arranged on the corresponding connecting plate 12 and the top plate 4, respectively. This design is beneficial to the use of the device. The plurality of dampers 13 are uniformly distributed on the base frame 1 and the positioning frame 2. This design can make the protective net 5 and the top plate 4 evenly disperse the pressure when impacted. The bottom ends of the plurality of fixing bolts 11 extend out of the fixing frame 10, and the bottom ends of the plurality of fixing bolts 11 are externally and threadedly provided with fixing nuts 15.
