Abstract
The utility model discloses a protective device for a scraper conveyor with the height adjustable. The protective device for the scraper conveyor can effectively protect slungshot. The protective device for the scraper conveyor comprises a baffle and a supporting plate. The supporting plate is provided with a guide limiting groove. The baffle is matched with the guide limiting groove in a sliding mode. The baffle is connected with a baffle lifting mechanism used for driving the baffle to slide along the guide limiting groove. The baffle lifting mechanism is a jack. A base seat of the jack is connected with the supporting plate. A push rod of the jack is connected with the baffle. A scraper conveyor cable trough connecting block is arranged at the bottom end of the supporting plate. A scraper conveyor middle trough supporting block is arranged at a position of a plate body of the supporting plate, wherein the position of the plate body of the supporting plate is arranged above the scraper conveyor cable trough connecting block. The purpose that the baffle rises or descends according to the practical demand is achieved through the baffle lifting mechanism. The baffle is supported by the supporting plate, can fend against the impact of a large stone. The protective device for the scraper conveyor is firm and reliable to use.
Description
Technical field
The utility model relates to a kind of protective device for scrapper conveyor.
Background technology
During the coalcutter coal cutting, coal mining machine roller can drive the pedestrian space that gathering coal and spoil are pounded support, hurts the staff and damages support.Therefore need to take certain safeguard procedures.At present, the main materials such as wire netting, waste and old adhesive tape and steel plate that use simply protect in the anti-slungshot of Inclined Full-mechanized Mining Face, and through practical application, effect is not fine.
Wire netting is prevented the slungshot device, is that wire netting one end is fixed on the support, and the other end is fixed on the scrapper conveyor cable duct.Advantage is: this apparatus structure is simple, can protect the part slungshot.Shortcoming is: when slungshot is larger, easily this protective device is damaged; When slungshot hour, can leap by the slit of wire netting the pedestrian space of support.This device can not play the bothersome effect of protection effectively.
Waste and old adhesive tape is prevented the slungshot device, is that waste and old adhesive tape is carried out cutting by the size of working face space of planes, is fixed on the support reducing good adhesive tape one end, and the other end is fixed on the scrapper conveyor cable duct.Advantage is: can allow waste and old material be reused; This device can block slungshot effectively.Shortcoming is: when slungshot was larger, easily the fixed position with this device damaged; To support to move the operating influences such as frame large, inconvenient downhole operations; When changing appearred in the driving surface mining height, this device can not play effectively protective action.
The anti-slungshot device of steel plate is steel plate to be cut into about 1.5 meters long, highly look face height and determine, with this Plate Welding on the scrapper conveyor cable duct.Advantage is: this apparatus structure is simple; The energy actv. blocks the slungshot of certain altitude.Shortcoming is: along with the variation of coal-face height, can not effectively block the slungshot of higher mining height.
The utility model content
It is adjustable and can effectively prevent the protective device for scrapper conveyor of slungshot that the technical matters that the utility model solves provides a kind of height.
The technical scheme that its technical matters that solves the utility model adopts is: the protective device that is used for scrapper conveyor, comprise baffle plate and stay bearing plate, be provided with the guide and limit groove on the stay bearing plate, baffle plate and guide and limit groove bearing fit are connected with the baffle plate lifting mechanism that slides along the guide and limit groove for driving baffle plate on the baffle plate.
Further be: described baffle plate lifting mechanism is jack, and the base of jack links to each other with stay bearing plate, and the propulsion arm of jack links to each other with baffle plate.
Further be: the bottom of stay bearing plate is provided with scrapper conveyor cable duct contiguous block, and the top that the plate of stay bearing plate is positioned at scrapper conveyor cable duct contiguous block with it is provided with the scraper conveyor middle groove back-up block.
The beneficial effects of the utility model are: can realize that by the baffle plate lifting mechanism baffle plate rises with actual needs or descends, and baffle plate supports by stay bearing plate, can keep out the impact than ratchel, use solid and reliable.
Description of drawings
Fig. 1 is the schematic diagram of the protective device for scrapper conveyor of the present utility model;
Be labeled as among the figure: baffle plate 1, stay bearing plate 2, propulsion arm 3, base 4, scraper conveyor middle groove back-up block 5, guide and limit groove 6, scrapper conveyor cable duct contiguous block 7.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
As shown in Figure 1, protective device for scrapper conveyor of the present utility model comprises baffle plate 1 and stay bearing plate 2, is provided with guide and limit groove 6 on the stay bearing plate 2, baffle plate 1 and guide and limit groove 6 bearing fits are connected with the baffle plate lifting mechanism that slides along guide and limit groove 6 for driving baffle plate 1 on the baffle plate 1.During use, can first above-mentioned protective device be fixed on the scrapper conveyor, rise or descend along guide and limit groove 6 by baffle plate lifting mechanism control baffle plate 1, and then baffle plate 1 can be adjusted to rational position according to actual demand.Can prevent effectively that by above-mentioned protective device slungshot from hurting sb.'s feelings or damage machine.For the ease of the protective device for scrapper conveyor of the present utility model is installed to scrapper conveyor, as shown in Figure 1, the bottom of stay bearing plate 2 is provided with scrapper conveyor cable duct contiguous block 7, and the top that the plate of stay bearing plate 2 is positioned at scrapper conveyor cable duct contiguous block 7 with it is provided with scraper conveyor middle groove back-up block 5.During installation, scrapper conveyor cable duct contiguous block 7 can be linked to each other with the scrapper conveyor cable duct, scraper conveyor middle groove back-up block 5 is linked to each other with intermediate channel on the scrapper conveyor.
The embodiment of above-mentioned baffle plate lifting mechanism has multiple, and for example the baffle plate lifting mechanism can be hydraulic ram, can be cylinder, can be the lifting mechanism of driven by motor etc.But in order to make designs simplification, be convenient to installation and maintenance, as shown in Figure 1, described baffle plate lifting mechanism is jack, and the base 4 of jack links to each other with stay bearing plate 2, and the propulsion arm 3 of jack links to each other with baffle plate 1.
