Abstract
The invention discloses a novel forearm expansion and contraction device which comprises a main arm (1) and a forearm (2). The main arm (1) is shorter than a traditional main arm. One end of the forearm (2) is connected with the main arm (1) through a connection joint (3). The other end of the forearm (2) is connected with a platform fence (5) through a swing cylinder (4). The connection joint (3) comprises a levelling cylinder (31) and a lifting cylinder (32). The levelling cylinder (31) is used for adjusting the balance of the platform fence (5). The lifting cylinder (32) is connected to the forearm (2). The function that the forearm (2) independently ascends and descends under the condition that other arm rests do not move is achieved. According to the novel forearm expansion and contraction device, on the basis of guaranteeing that the operation height and the arm rest strength are constant, the storage length of the prior art is greatly reduced, and a storage space is substantially reduced.
Description
Technical field
The invention belongs to construction machinery industry, field of aerial work, particularly relate 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.
Beneficial effect of the present invention: the present invention 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 object, technical solutions and advantages of the present invention clearly, describe the present invention below in conjunction with the drawings and specific embodiments.
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 6500 mm, 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 invention, 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 invention and method.
