Description
Technical field
The utility model relates to a kind of high-altitude operation engineering machinery fly jib structure with six bar levelling gears.
Background technology
At present, the application of aloft work such as Elevating platform fire truck, aerial platform construction machinery and equipment in producing, living more and more widely.High-altitude operation engineering machinery all has usually and is used for the workplatform of manned or loading, this workplatform need be in the process of lifting the maintenance level.Concrete structure is to be rotatably connected to fly jib with principal arm, and fly jib switches through moving oil cylinder, is connected with platform support in the lower end of fly jib by four-bar mechanism, has one above platform support, and work room is arranged on the platform.During work, rotational fuel tank drives fly jib and rotates, platform is rotated thereupon, reach the purpose of lifting, in the lifting process, platform rotates with respect to fly jib, make platform remain horizontality, platform is finished by four-bar linkage with respect to the rotation of fly jib, the fly jib of this structure, because the restriction of four-bar mechanism characteristic, platform is little with respect to the rotational angle of fly jib, make platform elevate a turnable ladder space and highly be restricted, some occasion is utilized the elevate a turnable ladder that existing this structure fly jib can't implementation platform.
Summary of the invention
The high-altitude operation engineering machinery fly jib structure with six bar levelling gears that the purpose of this utility model provides that a kind of platform is big with respect to the fly jib rotational angle, platform elevate a turnable ladder space is big, be suitable for various no occasions overcomes the deficiencies in the prior art.
High-altitude operation engineering machinery fly jib structure with six bar levelling gears of the present utility model, comprise fly jib, platform support that is connected with fly jib and platform, platform support and platform support connecting arm join, platform support connects and the bottom of fly jib is rotationally connected by rack shaft, on fly jib by a be rotationally connected end of second connecting rod of fixed rotating shaft, the other end of second connecting rod is rotationally connected by an end of movable rotation-shaft and first connecting rod, the other end of first connecting rod, be rotationally connected by the 4th bearing pin and platform support connecting arm, join by second oil cylinder with second piston rod that second oil cylinder matches between described movable rotation-shaft and the fly jib.
High-altitude operation engineering machinery fly jib structure with six bar levelling gears of the present utility model, wherein said platform support is captiveed joint with connection box, be rotationally connected by second bearing pin between connection box and the platform support connecting arm, be provided with the oil cylinder supporting and adjusting device of symmetry in the both sides of platform support and platform support connecting arm.
High-altitude operation engineering machinery fly jib structure with six bar levelling gears of the present utility model compared with prior art has the big advantage of rotational angle between platform and the fly jib, and platform elevate a turnable ladder space and height change scope are big, are suitable for more occasions.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is an A portion enlarged diagram shown in Figure 1.
The specific embodiment
As shown in Figure 1, 2: 19 is principal arm, termination at principal arm 19 is rotatably connected to bending fly jib 20 by fly jib rotating shaft 21, is provided with rotational fuel tank 18 between the termination of fly jib 20 and principal arm 19, during operation, drive rotational fuel tank 18 actions by hydraulic control device, fly jib is rotated.
1 is platform, is provided with the operating room above platform.The below of platform 1 is fixedly connected with platform support 2, and the end welding or the bolt of platform support 2 are connected with connection box 7.Be rotationally connected by second bearing pin 8 between connection box 7 and the platform support connecting arm 10.
Platform support connecting arm 10 is rotationally connected by rack shaft 12 with the bottom of fly jib 20, on fly jib 20 by a be rotationally connected end of second connecting rod 14 of fixed rotating shaft 15, the other end of second connecting rod 14 is rotationally connected by the end of movable rotation-shaft 13 with first connecting rod 11, the other end of first connecting rod 11 is rotationally connected with platform support connecting arm 10 by the 4th bearing pin 22.
The termination of the movable rotation-shaft 13 and second oil cylinder 16 is rotationally connected, and is connected by rotating shaft between the upper end of second piston rod 17 that matches with second oil cylinder 16 and the fly jib 20.
Be provided with the oil cylinder supporting and adjusting device of symmetry in the both sides of platform support 2 and platform support connecting arm 10, concrete structure is to be welded with hinge ear 3 on platform support 2, the termination of hinge ear 3 by first bearing pin 4 and first oil cylinder 5 joins, and the external end head of the first piston bar 6 that matches with first oil cylinder 5 is rotationally connected by croisillon de joint homocinetique 9 and platform support connecting arm 10.
Working process is as follows: it is that the center rotates with fly jib rotating shaft 21 that rotational fuel tank 18 drives fly jib 20, fly jib 20 drives platform 1 and rises, at this moment, platform 1 meeting run-off the straight, platform 1 is connected to angular transducer, the signal that angular transducer measures makes 16 actions of second oil cylinder by control setup, second piston rod 17 is made expanding-contracting action, second connecting rod 14, first connecting rod 11, and platform support connecting arm 10 moves thereupon, make platform support connecting arm 10, connection box 7, platform support 2, platform 1 rotates, offset platform 1 bevelled angle, made platform 1 remain horizontality, reached the leveling purpose.In course of action, the leveling angle is big, and is applied widely.
