Description
Technical Field
The utility model relates to a coal mining equipment technical field especially relates to a transportation belt support frame and combine and dig quick-witted equipment.
Background
In recent years, along with the continuous improvement of mechanization degree, especially the improvement of coal mining equipment and coal mining technology level, the coal production capacity is greatly improved again, so that the requirements of the mining and taking-over relationship of coal mines are more and more strict and tense. In order to ensure the realization of normal excavation linking relation, the only feasible method is to improve the fully-mechanized excavation single-entry level of the coal roadway, so that the normal production of the coal mine can be ensured.
The coal discharging process of the fully-mechanized excavating machine mainly depends on a first conveyor and a second conveyor of the fully-mechanized excavating machine, the tail of the second conveyor is connected with the fully-mechanized excavating machine through a connecting shaft, and a guide rail trolley of the head of the second conveyor is lapped with a tail frame of a rubber belt conveyor to complete a coal discharging procedure. The second conveyor of the roadheader is about 18m in length and is divided into six intermediate frames, and each two intermediate frames are connected by connecting pieces with fixed lengths. And after the fully-mechanized excavating machine finishes coal cutting and permanent support, the second conveyor of the fully-mechanized excavating machine moves forwards on the tail frame of the rubber belt conveyor along with the fully-mechanized excavating machine. Except for the matched size relationship between the second conveyor of the roadheader and the rubber belt conveyor, the effective size of the second conveyor of the roadheader moving on the tail of the rubber belt conveyor is 16 m. At present, with the optimization of a supporting process, the simplification of labor organization and the continuous improvement of the operation level of workers, the fully mechanized excavation footage is improved from 14 m/day to 19 m/day in the past. When the daily entry length of the fully-mechanized excavating working face is larger than the effective distance of the second conveyor of the fully-mechanized excavating machine moving on the tail frame of the rubber belt conveyor, the last production class is stopped for two hours, the rubber belt conveyor is prolonged, the production link is increased, the starting time of the fully-mechanized excavating machine is reduced, the fully-mechanized excavating machine cannot continuously operate, and the space for improving the single-entry level of fully-mechanized excavating is compressed.
According to the existing problems, the length of the second conveyor of the fully-mechanized excavating machine is lengthened, the length of the middle frame is increased from 6 sections to 8 sections, and the length of the second conveyor of the fully-mechanized excavating machine is increased from 18m (the effective length 16m) to 24m (the effective length 22 m). After the length of the second conveyor of the fully-mechanized excavating machine is increased, normal production of a production class can be ensured in the early stage, and the problems that the rubber belt conveyor needs to be extended in the production class and the starting time of the fully-mechanized excavating machine is shortened are solved. However, the bridge type spanning length of the second conveyor of the roadheader is too large, the second conveyor of the roadheader is only supported by the head and the tail, the middle of the second conveyor of the roadheader has no supporting point, and in the production process of the second conveyor of the roadheader, the middle frame deforms and breaks due to the fact that the strength of the middle frame of the second conveyor does not meet the requirement, so that safety production is affected.
