The specific embodiment
Further specify the utility model below in conjunction with Figure of description.
As shown in the figure, the manual flattening device of the jumping pit comprises the line slide rail 1 that is fixedly installed on the both sides, sand pit, be slidingly matched on every line slide rail 1 two linear slider 2 are set, between the linear slider 2 of both sides, sand pit, be fixedly installed crane span structure 3, crane span structure 3 lower ends are fixedly installed one group of bearing block, be equipped with one group of turning cylinder between the bearing block, fixed symmetrical arranges one group of scraping blade 20 and one group of loose sand brush 19 on the turning cylinder.Turning cylinder can be one in the practical application, also can be many.
As preferred structure, crane span structure 3 lower ends are fixedly installed 4 bearing blocks and are respectively at the side shaft holder 14 of both sides and two middle bearing brackets 8 between side shaft holder 14, and the first turning cylinder 18, the second turning cylinder 17 and the 3rd turning cylinder 15 are being set respectively between 4 bearing blocks.Wherein the outboard end of the first turning cylinder 18 and the 3rd turning cylinder 15 is supported by the side shaft holder 14 that is fixed on the crane span structure 3, and the medial extremity of the first turning cylinder 18 and the 3rd turning cylinder 15 connects respectively the second turning cylinder 17 by the middle bearing bracket 8 that is fixedly installed on the crane span structure 3.
The concrete syndeton of the first turning cylinder 18, the second turning cylinder 17 and the 3rd turning cylinder 15 is as follows: be fixedly installed respectively spindle nose 11 on the outboard end of the first turning cylinder 18 and the 3rd turning cylinder 15, the spindle nose 11 of the first turning cylinder 18 and the 3rd turning cylinder 15 respectively be arranged on side shaft holder 14 in side bearing 13 socket cooperates, side bearing 13 covers 12 by the side bearing that arranges and is fixed in the side shaft holder 14.The second turning cylinder 17 two ends are fixedly installed respectively connecting axle 16, connecting axle 16 cooperates with intermediate bearing 9 socket in being arranged on middle bearing bracket 8, intermediate bearing 9 is fixed in the middle bearing bracket 8 by the plummer block keep 7 that arranges, the other end socket of connecting axle 16 arranges adapter sleeve 10, the medial extremity of socket the first turning cylinder 18 or the 3rd turning cylinder 15 on the adapter sleeve 10.Like this so that the first turning cylinder 18, the second turning cylinder 17 and the 3rd turning cylinder 15 link together.
In order to be fixedly installed pull bar 6 at the second turning cylinder 17 so that turning cylinder can rotate, there is a hole to be used for wearing forward stay cord 21 and backward stay cord 22 on the pull bar 6, during the pulling stay cord turning cylinder is rotated.The angle of rotating in order to limit turning cylinder, be fixedly installed Limit screw 4 at the right-hand member of the first turning cylinder 18 and the left end of the 3rd turning cylinder 15, Limit screw 4 connects with the front limit screw 501 that is arranged on both sides, middle bearing bracket 8 front and back and rear stop screw 502 gears and cooperates.
The sportsman is when jumping, and crane span structure 3 is in the rear end in sand pit.The sportsman Shamian Island out-of-flatness occurs after jumping, spur forward stay cord 21, at first pull bar 6 is stressed, the first turning cylinder 18, the second turning cylinder 17 and 15 rotations of the 3rd turning cylinder, loose sand brush 19 on the turning cylinder changes Shamian Island over to, turning cylinder stops operating when the Limit screw 4 on the turning cylinder forwards front limit screw 501 to, and Limit screw 4 is in the b position, and this moment, loose sand brush 19 and scraping blade 20 were in position shown in Figure 5.Spur forward stay cord 21, crane span structure 3 moves forward again, and drives loose sand brush 19 and moves forward, the beginning loose sand.Brushing 19 lower ends because of loose sand is comb types, and its effect is loose sand, and the upper end is template, can jump the too high Shamian Island of rear appearance to the sportsman and carry out tentatively smooth.
Loose sand finishes when crane span structure 3 is moved the front end in sand pit to, begins the anti-whole Shamian Island of evening up.Stay cord 22 before after the pulling, at first pull bar 6 stressed the first turning cylinders 18, the second turning cylinder 17 and 15 rotations of the 3rd turning cylinder, the scraping blade 20 on the turning cylinder turns to Shamian Island, and loose sand brush 19 leaves Shamian Island.Turning cylinder stops operating when the Limit screw 4 on the turning cylinder forwards rear stop screw 502 to, and Limit screw 4 is in a position, and this moment, loose sand brush 19 and scraping blade 20 were in as shown in Figure 4 position.Spur forward stay cord 21, crane span structure 3 moves forward again, and drives scraping blade 20 mobile backward, begins smooth Shamian Island.Crane span structure 3 is moved to the rear end in sand pit, the smooth end of Shamian Island, the sportsman can jump.
Shown in the above and the figure only is preferred embodiment of the present utility model.Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
