Abstract
The utility model relates to a light-duty supporting drawing template used for coalmine working face conveyer equipment, the utility model adopts a key part of the coalmine working face conveyer equipment, and solves the problem existing in the prior art that a circular link chain and a median plate of a conveyor are worn, and the problem that the abrasion of the median plate is not uniform. The supporting drawing template of the utility model is clamped on the circular link chain of the conveyor, the supporting drawing template adopts a symmetrical structure of the upper and the lower drawing templates and the both ends of the upper drawing template and the both ends of the lower drawing template are connected laterally through bolts. Different from the common drawing template, the light-duty supporting drawing template of the utility model has small and short structure, light weight, is not contacted with the ledge at the both sides, is uniformly distributed between the common drawing templates, and has effective support and protective function on the circular link chain connecting with the drawing template. In addition, the light-duty supporting drawing template is used together with the common drawing template, the utility model can ensure that the median plate is worn uniformly, and the coal carrying efficiency is improved. The light-duty supporting drawing template of the utility model is connected laterally and horizontally through bolts, can be installed and dismantled under the tensioning status of the circular link chain, and the use and the maintenance are convenient.
Description
Technical field
The utility model relates to a kind of light-duty support scratch board that is used for conveying equipment of coal mine work area, belongs to the kernel component of conveying equipment of coal mine work area.
Background technology
The driving surface load transfer device is the core equipment of coal mine machinery coal mining, and it and coal excavation apparatus, the supporting use of support apparatus can realize the efficient output of coal.Slat conveyer is provided with the middle plate of putting coal and the ledge of middle plate both sides, and middle plate top is provided with the scraper plate that round-link chain drives, and scraper plate is provided with on chain at interval.Excessive when flight pitch, round-link chain contacts with middle plate under the pressure effect of deadweight and coal, causes the wearing and tearing of round-link chain and middle plate; Too small when flight pitch, the weight of scraper plate unit length increases, and then increases the no-load power consumption of system.Therefore, scraper plate and round-link chain are as the parts of conveyer key, and its resistance to abrasion and reliability are technical barriers of puzzlement coal machine industry always.
The utility model content
The purpose of this utility model is to provide a kind of light-duty support scratch board that is used for conveying equipment of coal mine work area, solves the wear problem of plate in the round-link chain that exists in the prior art and the conveyer, and problem such as middle plate irregular wear.
The technical solution of the utility model is:
The support scratch board that is used for conveying equipment of coal mine work area, support scratch board are upper and lower scraper plate symmetrical structure, and support scratch board is installed on the round-link chain of conveyer.
The described support scratch board that is used for conveying equipment of coal mine work area, upper and lower scraper plate two ends laterally connect by bolt.
The described support scratch board that is used for conveying equipment of coal mine work area, upper and lower scraper plate two ends are respectively equipped with connection ear with holes, and upper and lower scraper plate passes engaging lug by bolt and laterally connects.
The described support scratch board that is used for conveying equipment of coal mine work area is provided with corresponding positioning boss in the middle of the upper and lower scraper plate, and two round-link chains that be arranged in parallel place respectively between the connection ear at positioning boss and two ends.
The described support scratch board that is used for conveying equipment of coal mine work area, the positioning boss of upper and lower scraper plate are located between two round-link chains that be arranged in parallel.
The described support scratch board that is used for conveying equipment of coal mine work area, the positioning boss of upper and lower scraper plate be located at round-link chain on cooresponding position, hole.
The beneficial effects of the utility model are:
1, the light-duty support scratch board of the utility model adopts symmetrical structure up and down, laterally connects by two bolts, has the amphicheirality on the mode of motion.Lengthwise dimension is shorter, and the scraper plate two ends do not contact with the ledge of plate both sides in the conveyer.Advantage: in light weight, be easy to carrying, can be under the round-link chain tensioning state Assembly ﹠Disassembly, operation and maintenance is convenient.
2, the light-duty support scratch board of the utility model is evenly distributed between the common scraper plate; by light-duty support scratch board is installed between common scraper plate; the round-link chain that connects scraper plate is played effective support and protective effect, reduced round-link chain and the wearing and tearing of putting plate in the conveyer that coal uses greatly.Simultaneously,, can make the whole uniform wear of middle scraper, improve and carry coal efficient by together using with conventional scraper plate.
3, the light-duty support scratch board of the utility model adopts austempering ductile iron materials A DI (Austemperedducted cast irons), has high strength, characteristics such as high-wearing feature, self-lubricating.
Description of drawings
Fig. 1-Fig. 3 is the overall installation figure of the utility model support scratch board.Wherein, Fig. 1 is a front view; Fig. 2 is a birds-eye view; Fig. 3 is a lateral plan.
Fig. 4 is the utility model support scratch board assembled figure.
Among the figure, 1 common scraper plate; 2 support scratch boards; 3 round-link chains; 4 upper scraping plates; 5 lower scraping plates; 6 connect ear; 7 positioning boss I; 8 bolts; 9 positioning boss II.
The specific embodiment
As Figure 1-3, the light-duty support scratch board 2 of the utility model is installed on the round-link chain 3 of conveyer, is evenly distributed between the common scraper plate 1.
As shown in Figure 4, the light-duty support scratch board 2 of the utility model is upper scraping plate 4, lower scraping plate 5 symmetrical structures, and structure is in full accord.Upper scraping plate 4, lower scraping plate 5 two ends are respectively equipped with connection ear 6 with holes, and upper scraping plate 4, lower scraping plate 5 pass connection ear 6 by bolt 8 and laterally connect; Be provided with corresponding positioning boss (positioning boss I7, positioning boss II9) in the middle of upper scraping plate 4, the lower scraping plate 5, two round-link chains that be arranged in parallel 3 place respectively between the connection ear 6 at positioning boss and two ends, thereby by the utility model support scratch board 2 with and on " cangue " shape structure of forming of connection ear 6,3 clampings of two round-link chains that be arranged in parallel are located.Positioning boss I7 on upper scraping plate 4, the lower scraping plate 5 is located between two round-link chains that be arranged in parallel 3, determines the spacing of round-link chain 3.Positioning boss II9 on upper scraping plate 4, the lower scraping plate 5 be located at round-link chain on cooresponding position, hole, be used for round-link chain 3 location.
The utility model has played effective supporting by between common scraper plate support scratch board being installed to the round-link chain that connects scraper plate, reduces the wearing and tearing of round-link chain and middle plate greatly.
