Abstract
The utility model discloses a novel forearm is flexible device, including main arm (1), forearm (2), main arm (1) is shorter than the size of traditional main arm, the one end of forearm (2) through connect joint (3) with main arm (1) is connected, the other end of forearm (2) is connected with platform fence (5) through swing hydro -cylinder (4), connect joint (3) including leveling cylinder (31), lift cylinder (32), the balance that leveling cylinder (31) were used for adjusting platform fence (5), lift cylinder (32) are connected on forearm (2), realize all making function that forearm (2) rise alone and descend under the motionless condition at other cantilever cranes. The utility model discloses guarantee equipment operation height with cantilever crane intensity in unchangeable, the general originally collect the length of size and dwindle by a wide margin, had saved the collection space by a wide margin.
Description
Technical field
The utility model belongs to construction machinery industry, field of aerial work, particularly relates to a kind of novel forearm retractor device.
Background technology
Existing boom type aerial platform jib is all longer in the market, and cause collection size comparatively large, required collection space is larger, is unfavorable for operation and collection.
Summary of the invention
Goal of the invention: design a kind of novel forearm retractor device, guarantee operation height and jib intensity constant while, the significantly collection size of reduction equipment.
Technical scheme: a kind of novel forearm retractor device, comprise principal arm 1, forearm 2, described principal arm 1 is shorter than the size of traditional principal arm, and one end of described forearm 2 is connected with described principal arm 1 by connecting joint 3, and the other end of described forearm 2 is connected with platform hurdle 5 by oscillating oil cylinder 4;
Described connection joint 3 comprises leveling cyclinder 31, elevating ram 32, and described leveling cyclinder 31 connects described principal arm 1, is used for regulating the balance on platform hurdle 5; Described elevating ram 32 is connected on forearm 2, realizes the function making forearm 2 rise separately and decline when other jib is all motionless;
The angle that swings on described oscillating oil cylinder 4 parametric controller hurdle 5;
Preferably, described novel forearm retractor device also comprises electric-control board 6, time in working order, performs the elongation of forearm 2 and the rising on platform hurdle 5 by the shift knob 61 on electric-control board 6; When collecting state, perform the contraction of forearm 2 and the decline on platform hurdle 5 by the shift knob 61 on electric-control board 6, as long as described principal arm 1 is convenient to case or collect with the angle of forearm 2; The action of described series is the electric component detail programming realization by being arranged on control system inside.
The beneficial effects of the utility model: the utility model guarantee equipment availability height and jib intensity constant while, the length of originally collecting size is significantly reduced, significantly saves collection space.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment:
As Fig. 1, a kind of novel forearm retractor device, comprise principal arm 1, forearm 2, described principal arm 1 is shorter than the size of traditional principal arm, described forearm 2 is connected with described principal arm 1 by the connection joint 3 of its one end, and described forearm 2 is connected with platform hurdle 5 by the oscillating oil cylinder 4 of the other end; The angle that swings on described oscillating oil cylinder 4 parametric controller hurdle 5.
As Fig. 2, described connection joint 3 comprises leveling cyclinder 31, elevating ram 32, and described leveling cyclinder 31 connects described principal arm 1, is used for regulating the balance on platform hurdle 5; Described elevating ram 32 is connected on forearm 2, realizes the function making forearm 2 rise separately and decline when other jib is all motionless.
As Fig. 3, during equipment contraction state with novel forearm retractor device, equipment total length is 4800mm, namely 4.8 meters; As Fig. 4, during legacy equipment contraction state not with novel forearm retractor device, equipment total length is 6500mm, namely 6.5 meters.Can find out, the equipment with novel forearm retractor device, than the equipment not with novel forearm retractor device, has saved the collection space of 1.7 meters.
Fig. 5, Fig. 6 then show respectively the equipment of being with novel forearm retractor device and the legacy equipment not with novel forearm retractor device in working order time schematic diagram, can find out, both total operation heights are the same, are all 15000mm, namely 15 meters.
Preferably, described novel forearm retractor device also comprises electric-control board 6, time in working order, performs the elongation of forearm 2 and the rising on platform hurdle 5 by the shift knob 61 on electric-control board 6; When collecting state, perform the contraction of forearm 2 and the decline on platform hurdle 5 by the shift knob 61 on electric-control board 6, as long as described principal arm 1 is convenient to case or collect with the angle of forearm 2; The action of described series is the electric component detail programming realization by being arranged on control system inside.
The foregoing is only preferred embodiments of the present utility model, not in order to limit the present invention, any amendment done within the spirit and principle of invention, equivalent replacement, improvement etc., all should be included within system architecture of the present utility model.
