Detailed description of the invention
If Fig. 1 is to shown in 3: a kind of chain wheel of embedded scraper transporter tensioner, including casing 1, mounting hole 11 is offered in the both sides of casing 1, a piece rotating shaft 2 that can move linearly in mounting hole 11 is installed in mounting hole 11, rotating shaft 2 is provided with sprocket wheel 21, an axle bed 22 it is separately installed with at the two ends of rotating shaft 2, it is respectively provided on two sides with an axle bed arrangement portion in casing 1, described axle bed arrangement portion includes the positioning strip 12 being fixed on mounting hole 11 both sides, a parallel passage is being gone out at casing 1 spaced surface by positioning strip 12, described axle bed 22 is placed in this passage, each axle bed 22 is mounted on a tensioner；
Described tensioner includes the hydraulic jack 3 that cylinder body end is fixed on axle bed 22, and the piston rod 34 of hydraulic jack 3 is fixing with casing 1 to be connected, and hydraulic jack 3 inner carrier 32 both sides oil pocket connects with a hydraulic oil pipe 33 respectively；
Also including that first gas spring the 41, second gas spring 42, air bottle 6 and air compressor machine 8, the first gas spring 41 and the second gas spring 42 are conventional hydro-pneumatic spring, hydro-pneumatic spring is prior art, is not set forth in detail at this；
As it is shown in figure 1, setting a hydraulic jack 3 above casing 1 is lower hydraulic jack 302 as upper hydraulic jack 301, the hydraulic jack 3 below casing 1, in upper hydraulic jack 301, the oil pocket on piston 32 left side is upper left oil pocket, and the oil pocket on the right of piston is upper right oil pocket；nullIn lower hydraulic jack 302, the oil pocket on piston 32 left side is bottom left oil pocket，Oil pocket on the right of piston 32 is bottom right oil pocket，Upper right oil pocket and bottom right oil pocket are the oil pocket near axle bed 22，Upper left oil pocket and upper right oil pocket are the oil pocket away from axle bed 22，Two hydraulic oil pipes 33 connected with upper right oil pocket and bottom right oil pocket respectively are connected to the hydraulic oil end of the first gas spring 41，Two hydraulic oil pipes 33 connected with upper left oil pocket and bottom left oil pocket are connected to the hydraulic oil end of the second gas spring 42，Gas end in the gas end of the first gas spring 41 and the second gas spring 42 is connected with air bottle 6 by an air hose 36 respectively，The air hose 36 that first gas spring 41 connects with air bottle 6 is provided with the first valve 51，Second valve 52 is installed on the air hose 36 that second gas spring 42 connects with air bottle 6，Air compressor machine 8 is connected with air bottle 6.
