Detailed description of the invention
below in conjunction with embodiment, the present invention is further illustrated.
embodiment:
a kind of large-scale round log transport sector, as shown in Figures 1 and 2, comprise transport tape 1, the surface of transport tape 1 is provided with arc-shaped transmission slot 21, transport tape 1 is provided with lower low water 2, is provided with lifting table 3 below lower low water 2, and lifting table 3 surface is provided with arc-shaped hold down groove 4, the drift angle of lifting table 3 is hinged with supporting seat 5, and supporting seat 5 is hinged with fixed block 6; The base angle of described lifting table 3 is connected with rotational fuel tank 7, and bottom and the fixed block 6 of rotational fuel tank 7 are hinged; Described rotational fuel tank 8 is also connected with hoist cylinder 7, and bottom and the fixed block 6 of hoist cylinder 7 are hinged.Also comprise hydraulic part, hydraulic part comprises fuel tank 10, fuel tank 10 is connected with quantitative hydraulic pump 11, quantitative hydraulic pump 11 is connected with check valve 12, check valve 12 is connected with the first two-position four-way solenoid directional control valve 13, and check valve 12 is held with the A of the first two-position four-way solenoid directional control valve 13 and is connected, the B end of the first two-position four-way solenoid directional control valve 13 is connected with fuel tank 10, the P end of the first two-position four-way solenoid directional control valve 13 is connected with the A end of the first three-position four-way electromagnetic directional valve 14, the T end of the first two-position four-way solenoid directional control valve 13 is connected with the B end of the second three-position four-way electromagnetic directional valve 15, the B end of the first three-position four-way electromagnetic directional valve 14 is connected with fuel tank (10), the P end of the first three-position four-way electromagnetic directional valve 14 is connected with hoist cylinder 7 rod end, hoist cylinder 7 rear end is connected with the A end of the second two-position four-way solenoid directional control valve 16, the B end of the second two-position four-way solenoid directional control valve 16 is connected with fuel tank, the P end of the second two-position four-way solenoid directional control valve 16 is connected with blwr 17, first three-position four-way electromagnetic directional valve 14 T end be connected with the first balance cock 18, first balance cock 18 be connected with the first two-position four-way solenoid directional control valve 16 A end, the A end of the second three-position four-way electromagnetic directional valve 15 is connected with fuel tank 10, the P end of the second three-position four-way electromagnetic directional valve 15 is connected with the second balance cock 19, the T end of the second three-position four-way electromagnetic directional valve 15 is connected with the rod end of rotational fuel tank 8, the rear end of rotational fuel tank 8 is connected with blwr 17, and the second balance cock 19 is connected with blwr 17, the A end of the first described two-position four-way solenoid directional control valve 13 is connected with electromagnetic relief valve 20, and electromagnetic relief valve 20 is connected with fuel tank 10.
principle of work: when round log transfers to lower low water through transport tape, lifting table is positioned at the below of the lower low water of transport tape, round log drops down onto on the hold down groove of lifting table, now rotational fuel tank action, lifting table drops to bottom, and the base angle of lifting table and ground are touched, now hoist cylinder action, lifting table rotates around base angle, and when fitting in the bottom surface of lifting table and ground, round log will tumble automatically.The oil sources of system is quantitative hydraulic pump, and the setting of system top pressure and the off loading control of quantitative hydraulic pump are realized by electromagnetic relief valve, the impact of check valve for preventing fluid from pouring in down a chimney and to pump.First two-position four-way solenoid directional control valve is made safety valve and is used, by the power on/off of the first two-position four-way solenoid directional control valve and the switching of control position thereof, control hoist cylinder and rotational fuel tank operationally people have 1 logical pressure oil, with the balance of 2 cylinders because road coordinates, when guaranteeing a cylinder action, another cylinder is motionless.The right side energising of the second three-position four-way electromagnetic directional valve makes the second three-position four-way electromagnetic directional valve switch to right position, the pressure oil of quantitative hydraulic pump enters rotational fuel tank through check valve, the first two-position four-way solenoid directional control valve and the second three-position four-way electromagnetic directional valve, it is horizontal surface that lifting table is adjusted to plane by rotational fuel tank, now the piston of blwr should be in high order end, the right side power-off of the second two-position four-way solenoid directional control valve makes the second two-position four-way solenoid directional control valve be in the left position of diagram, and blwr large chamber fluid can not be discharged; The left side energising of the first three-position four-way electromagnetic directional valve makes the first three-position four-way electromagnetic directional valve switch to left position, pressure oil enters hoist cylinder cavity of resorption through the first three-position four-way electromagnetic directional valve, lifting table is descending, and because intensifier piston is in low order end, therefore hydraulic actuating cylinder is discharged without fluid.After lifting table lands, under Gravitative Loads, the piston of the fluid promotion blwr in the large chamber of rotational fuel tank moves to left, and the bottom surface of lifting table is landed, the second two-position four-way solenoid directional control valve power-off.During lifting, principle of work is just in time contrary, finally completes rising and the decline of lifting table.
