Abstract
The utility model discloses a kind of telescoping mechanism, comprise more than three groups or three groups side by side serial connection and together with in each other can simultaneous retractable motion telescopic unit assembly, be connected in series side by side successively by contiguous block between each group of described telescopic unit assembly, and surround a polygonal framed structure, described telescopic unit assembly comprises many group head and the tail telescopic unit hinged successively, described telescopic unit comprises two telescopic booms, by respective centre cross-articulation between telescopic boom and telescopic boom; Each group of telescopic unit assembly can be synchronized with the movement, and improves flexible stability, makes whole telescoping mechanism uniform force, and the telescopic boom of each cross-articulation forms triangular structure, effectively can ensure the superpower stability of traveling comfort and spatial structure.
Description
Technical field
The utility model relates to engineering machinery field, relates to a kind of telescoping mechanism particularly.
Background technology
Telescoping mechanism is a kind of important feature of elevator machinery.The telescoping mechanism of hoisting crane comprises arm frame telescopic mechanism and supporting leg jack.The effect of arm frame telescopic mechanism changes jib length, to obtain amplitude and the lifting altitude of needs, meets job requirements.The purposes of supporting leg jack is the area of base increasing hoisting crane, and the gradient in adjustment place, improves stability against overturning, increase load-carrying ability.
At present, a lot of telescoping mechanism, particularly large-scale traditional telescoping mechanism comprises top frame, underframe is connected with the auxiliary frame head and the tail in the middle of it, and stretched by the mode that slippage or large section fold, stressed and the stability of this mechanism is poor, cannot bear too high pressure, when the scope that telescoping mechanism is flexible is longer, its top is rocked larger; This mechanism can not stretch oversize because power is restricted, the arm of force is very heavy, and the height stretched, length all have sex-limited; This mechanism structure is complicated, cost is high, and transfer transport is all more difficult; And can not run fast, such as when fire-extinguishing and lifesaving, length and highly can determine rescue whether success, the rate of stretch determines the efficiency of rescue.So it becomes the deadly defect of tall-building fire fighting.
Utility model content
In order to overcome the defect that traditional telescoping mechanism exists, the utility model provides a kind of telescoping mechanism, often organize unit can be synchronized with the movement, and merogenesis segmentation energy supplying power simultaneously can be carried out, improve flexible stability and the alignment of forces system of super large, make whole telescoping mechanism uniform force, can effectively fast and ensure traveling comfort.
The utility model solves the technical scheme that its technical matters adopts: a kind of telescoping mechanism, it is characterized in that: described telescoping mechanism comprise more than three groups or three groups side by side serial connection and together with in each other can simultaneous retractable motion telescopic unit assembly, be connected in series side by side successively by contiguous block between each group of described telescopic unit assembly, and surround a polygonal framed structure, described telescopic unit assembly comprises many group head and the tail telescopic unit hinged successively, described telescopic unit comprises two telescopic booms, by respective centre cross-articulation between telescopic boom and telescopic boom.
As preferably, the centre of described telescopic boom is provided with centre hole, centre hole inner sleeve bearing, and the bearing between two telescopic booms intersected is connected by turning cylinder.
Preferably, the two ends of described telescopic boom are provided with connecting bore, connecting bore inner sleeve bearing, and two between each telescopic unit intersect telescopic boom respectively by the connection of turning cylinder correspondence.
Preferably, the two ends of described turning cylinder are provided with jump ring, and are lined with pad.
Preferably, be hinged on contiguous block by the end of telescopic boom between each group of described telescopic unit assembly and connect.
The beneficial effects of the utility model are: be combined to form telescopic unit assembly by the telescopic unit that several is made up of two telescopic boom cross-articulation head and the tail are hinged successively, by by contiguous block, the telescopic unit assembly of more than three groups or three groups connection is combined to form telescoping mechanism again, simplification group connects configuration, save material cost, improve effectiveness of performance, and the motion of each group telescopic unit component synchronization, improve flexible stability, make whole telescoping mechanism uniform force, and the telescopic boom of each cross-articulation forms triangular structure, effectively can ensure traveling comfort; Can greatly increase the arm of force, alleviate overall weight, reduce the volume after bouncing back, convenient transport and stock.

Detailed description of the invention
The technical matters solved to make the utility model, technical scheme and beneficial effect are clearly understood, below in conjunction with accompanying drawing and embodiment, are further described the utility model.Should be appreciated that embodiment described herein only for explaining the utility model, and be not used in restriction the utility model.
As Figure 1-4, a kind of telescoping mechanism of the utility model, comprise three groups be connected in series side by side and together with in each other can simultaneous retractable motion telescopic unit assembly, be connected in series side by side successively by contiguous block 2 between each group of telescopic unit assembly, and surround a leg-of-mutton framed structure, telescopic unit assembly comprises many group head and the tail telescopic unit hinged successively, telescopic unit comprises two telescopic booms 1, by respective centre cross-articulation between telescopic boom 1 and telescopic boom 1, the centre of telescopic boom 1 is provided with centre hole 3, centre hole 3 inner sleeve bearing 4, bearing 4 between two telescopic booms 1 intersected is connected by turning cylinder 5, the two ends of telescopic boom 1 are provided with connecting bore 6, connecting bore 6 inner sleeve bearing 4, two between each telescopic unit intersect telescopic boom 4 respectively by the connection of turning cylinder 5 correspondence, wherein the two ends of turning cylinder 5 are provided with jump ring 7, and are lined with pad 8, for strengthening the firm of telescoping mechanism and stability.
Preferably, connection on contiguous block 2 is hinged on by the end of telescopic boom 1 between each group telescopic unit assembly.
As illustrated in figs. 5-7, a kind of telescoping mechanism of utility model can also by four groups, five groups, six groups even more multi-expansion unit block combine and form.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all any amendment, on an equal basis replacement and improvement etc. done within spirit of the present utility model and principle, all should drop within protection domain of the present utility model.
