[0057] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions in the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0058] Below in conjunction with Figures 1 to 8 Describe the machine room chassis of the present utility model.

[0059] AsFigures 1 to 8 As shown, the machine room chassis provided by the embodiment of the utility model includes a first bearing frame 1, a second bearing frame 2 and a third bearing frame.

[0060] Specifically, the first carrier 1 has a first equipment carrying area 11, a pitch carrying area 12 and a second equipment carrying area 13 distributed in sequence along the lateral direction. The pitch carrying area 12 is used to carry the pitch driving mechanism, and the second equipment carrying area 13 and the third equipment carrying area 21 are used to carry auxiliary equipment.

[0061] The second carrier frame 2 has a third equipment bearing area 21, a lifting bearing area 22 and a fourth equipment bearing area 23 which are sequentially distributed in the transverse direction. The lifting bearing area 22 is used to bear the lifting drive mechanism, and the third equipment bearing area 21 and the fourth equipment bearing area 23 are used to bear auxiliary equipment.

[0062] The third carrier frame has a fifth equipment carrying area 31, a traction carrying area 32 and a sixth equipment carrying area 33 distributed in sequence along the lateral direction. The traction carrying area 32 is used to carry the traction drive mechanism, and the fifth equipment carrying area 31 and the sixth equipment carrying area 33 are used to carry auxiliary equipment.

[0063] The first carrier frame 1 , the third carrier frame and the second carrier frame 2 are sequentially distributed along the longitudinal direction, and the third carrier frame connects the first carrier frame 1 and the second carrier frame 2 together.

[0064] With such arrangement, the machine room chassis is divided into blocks according to the distribution of the pitch drive mechanism, the lifting drive mechanism and the traction drive mechanism in the machine room. The size of each block is relatively small relative to the overall machine room chassis, which is conducive to the positioner displacement. At least the first carrier frame 1 and the second carrier frame 2 can be produced automatically. After the first carrier frame 1 and the second carrier frame 2 are produced respectively, the third carrier frame is formed by manual welding between the first carrier frame 1 and the second carrier frame 2. When the third carrier frame is formed, the first carrier frame 1 and the second carrier frame 2 are also fixedly connected together, thereby completing the processing and manufacturing of the machine room chassis. During the processing and manufacturing process, the amount of manual operation is significantly reduced, the labor intensity is reduced, and the manufacturing efficiency is improved, which solves the problem of low manual manufacturing efficiency and high labor intensity caused by the chassis of the machine room in the prior art that the chassis cannot be produced automatically due to its large size.

[0065] It should be noted that the auxiliary equipment in the machine room includes an electrical room, electrical cabinets, tool cabinets, floor windows, etc. After splicing the first carrier 1, the second carrier 2, and the third carrier together, the first equipment bearing area 11 of the first carrier 1, the third equipment bearing area 21 of the second carrier 2, and the fifth equipment bearing area 31 of the third carrier are distributed longitudinally. The first equipment bearing area 11, the third equipment bearing area 21, and the fifth equipment bearing area 31 are connected together and are used for the electrical room as a whole. The second equipment bearing area 13 of the first carrier 1 is used to bear the electrical cabinet, the fourth equipment bearing area 23 of the second carrier 2 is used to bear the tool cabinet, and the sixth equipment bearing area 33 of the third carrier is used to bear the floor window and the electrical cabinet.

[0066] The longitudinal dimensions of the first carrier 1, the second carrier 2, and the third carrier are determined according to the longitudinal dimensions of the pitching drive mechanism, the hoisting drive mechanism, and the traction drive mechanism respectively. When the longitudinal dimension of the area formed by splicing the first equipment bearing area 11 of the first carrier 1, the third equipment bearing area 21 of the second carrier 2, and the fifth equipment bearing area 31 of the third carrier together does not meet the requirements of the electrical room for the longitudinal dimension, a fourth carrier can also be equipped for the machine room chassis, so that the fourth carrier is located on the side of the second carrier 2 away from the first carrier 1, and the fourth carrier corresponds to the third equipment bearing area 21 of the second carrier 2.

[0067] The fourth carrier can be formed by connecting multiple fourth connecting profiles.
