Abstract
The utility model relates to a roller wheel type telescoping boom, which includes a fixing boom (1), a telescoping boom (2), an oil cylinder (3), a steel wire rope (4), vertical roller wheels (5) and lateral roller wheels (6), wherein the vertical roller wheels (5) and the lateral roller wheels (6) are fixed on the telescoping boom (2); the telescoping boom (2) and the fixing boom (1) are connected together; the roller wheels support the telescoping boom (2) inside the fixing boom (1); the vertical roller wheels (5) on the left and the right sides bear the vertical force; the two lateral roller wheels (6) are respectively arranged above and under the vertical roller wheels (5), and used for bearing the lateral force and hydraulically driving the oil cylinder (3) to enable the telescoping boom (2) to extend or retract; and the steel wire rope (4) is connected with the telescoping boom (2). The lateral force of the boom in the utility model is born by the four lateral roller wheels, and the roller wheel structure changes the sliding friction of the boom into the rolling friction, thereby greatly reducing the friction resistance.
Description
Technical field
The utility model relates to a kind of arm, relates in particular to a kind of roller type telescoping boom, applicable to ship domain.
Background technology
Requirement according to life peculiar to vessel, be in heel 200 and combine under 100 the worst sea situation of inclining at boats and ships, the equipment that hangs life boat should be able to be emitted life boat safety under the situation of dead electricity, the requirement that this just requires this equipment to have enough stored energy and bear very big side force; Existing such telescoping boom adopts sliding block type structure mostly.This technology is used more extensive now, such as the telescoping boom on our the common wheel crane; The major defect of slide block type arm is to bear big side force, and friction drag is too big.
The utility model content
1, technical matters to be solved:
Provide a kind of at above not enough the utility model and can bear big side force, stretched out and take in the little roller type telescoping boom of friction drag.
2, technical scheme:
The utility model comprises fixedly arm, telescoping boom, oil cylinder, steel rope, vertical wheel, side direction roller; Vertical wheel and side direction roller are fixed on the telescoping boom, telescoping boom and fixedly arm link together, by roller at fixing arm internal support telescoping boom, the vertical wheel of the left and right sides is born vertical power, be respectively equipped with two side direction rollers up and down in vertical wheel, be used to bear side force, hydraulic driving oil cylinder stretches out telescoping boom or takes in, and steel rope connects on the telescoping boom.
3, beneficial effect:
The side force of arm of the present utility model is born by four side direction rollers, owing to adopted roller structure, makes the cliding friction of original arm become friction of rolling, and friction drag is greatly reduced.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that A of the present utility model is to enlarged drawing.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the roller type telescoping boom comprises fixedly arm 1, telescoping boom 2, oil cylinder 3, steel rope 4, vertical wheel 5, side direction roller 6; Vertical wheel 5 and side direction roller 6 are fixed on the telescoping boom 2, telescoping boom 2 and fixedly arm 1 link together, at fixing arm 1 internal support telescoping boom 2, and transmit live load by roller.
The vertical wheel 5 of the left and right sides is born vertical power, be respectively equipped with two side direction rollers 6 up and down in vertical wheel 5, be used to bear side force, then by hydraulic driving oil cylinder 3, telescoping boom 2 is stretched out or take in, steel rope 4 connects on the telescoping boom 2, steel rope 4 stretching out, takeing in and moving up and down with telescoping boom 2.
Though the utility model with preferred embodiment openly as above; but they are not to be used for limiting the utility model; anyly have the knack of this skill person; in the spirit and scope that do not break away from the utility model; can do various variations or retouching from working as, what therefore protection domain of the present utility model should be defined with the application's claim protection domain is as the criterion.
Claims (1)
