Abstract
The utility model discloses a detachable supporting chain mechanism, and belongs to the technical field of engineering machinery parts. The detachable supporting chain mechanism comprises two rows of supporting chain plates which are installed on an upper cover plate of a track frame and parallelly placed and a fixing device of the supporting chain plates. The supporting chain plates are arch-shaped, supporting parts are arranged in the middle of the supporting chain plates, the height of the bottoms of the supporting parts is equal to the height of the two ends of the supporting chain plates, the fixing device is composed of fixing plates which are located at the two ends of the supporting chain plates and a box type structure, one ends of the supporting chain plates are inserted in the box type structure, and the other ends of the supporting chain plates are clamped in the fixing plates and fixed by hinge pins. The detachable supporting chain mechanism has the advantages of improving assembling efficiency, reducing disassembling and assembling difficulties and being more beneficial to being disassembled and replaced.
Description
Technical field
The utility model relates to a kind of detachable holder chain mechanism, belongs to engineering mechanical components fixed form technical field.
Background technology
The holder chain mechanism is a kind of mechanism that is applied to auxiliary holder sprocket wheel on the crawler crane, and it is mainly used in slowing down the wearing and tearing between caterpillar block and the track frame, is supporting caterpillar block weight simultaneously.The fixed sturcture that comprises link-supporting plate and link-supporting plate; Crawler crane is in the process of walking, owing to the deadweight or lax reason can cause caterpillar block sagging, sagging caterpillar block contacts and produces cliding friction with the holder chain mechanism, because caterpillar block tread hardness ratio is higher, resistance to abrasion is strong, so friction can cause the wearing and tearing of link-supporting plate.When fraction time was long, the link-supporting plate size can change gradually, did not have its due effect until the holder chain mechanism, after link-supporting plate lost efficacy, in order to guarantee the normal use of crawler crane, must change link-supporting plate.
Be accompanied by the fast development of crawler crane and the lifting gradually of user's request, the client has higher requirement to convenience and the efficient of hoisting crane dismounting, in the prior art, the holder chain mechanism form of crawler crane as shown in Figure 3, link-supporting plate 2 is assemblied on the track frame 7, can support caterpillar block 6 and avoid it sagging; Installation method as shown in Figure 4, welded nut plate 8 on the upper cover plate 3 of track frame 7 is installed to link-supporting plate 2 on the track frame 7 by bolt then.Adopt this technology when dismounting, mainly to have problem aspect following two:
1, concerning manufacturer, the holder chain mechanism needs with impact wrench bolt to be carried out fastening when mounted, because number is many, causes efficiency of assembling not high; For the user, when changing the link-supporting plate that holds in the palm in the chain mechanism, need be equipped with Special Equipment and dismantle with fastening.
2, when changing the link-supporting plate that holds in the palm in the chain mechanism, if bolt generation corrosion, just be difficult to disassemble, even might need nutplate is sliced off earlier just and can dismantle, again the welded nut plate fixes then, so just be equivalent to whole holder chain mechanism is changed, and replacing is wasted time and energy.
Summary of the invention
At the problem that above-mentioned prior art exists, the utility model provides a kind of detachable holder chain mechanism, improves the efficient of assembling, is more conducive to dismounting and change.
To achieve these goals, the technical solution adopted in the utility model is: a kind of detachable holder chain mechanism, comprise that being installed in two on the track frame upper cover plate arranges the link-supporting plate of parallel placement and the anchor fitting of link-supporting plate, described link-supporting plate is arc, the centre is provided with support zone, the support zone bottom equates with link-supporting plate two ends height, described anchor fitting is by fixedly adapter plate and the box-structure at link-supporting plate two ends are formed, one end of link-supporting plate inserts in the box-structure, and the other end snaps in adapter plate and fixed by bearing pin.
The end that described link-supporting plate inserts box-structure is wedge shape, plays good directional tagging, and dismounting is more convenient efficient.
The utility model has carried out accommodation at original structural shape, and assembling form is adjusted, and adopts link-supporting plate one end is spacing with box, that an end fixes with bearing pin mode.This mode has improved the efficient of assembling greatly, also is more conducive to dismounting and change.
Description of drawings
Fig. 1 is scheme of installation of the present utility model;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is existing holder chain mechanism structural representation;
Fig. 4 is existing holder chain mechanism scheme of installation.
Among the figure: 1, box-structure, 2, link-supporting plate, 3, upper cover plate, 4, bearing pin, 5, adapter plate, 6, caterpillar block, 7, track frame, 8, nutplate.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2: the utility model comprises that being installed in two on track frame 7 upper cover plates 3 arranges the link-supporting plate 2 of parallel placement and the anchor fitting of link-supporting plate 2, described link-supporting plate 2 is arc, the centre is provided with support zone, the support zone bottom equates with link-supporting plate 2 two ends height, in order to strengthen the bearing force of link-supporting plate 2, described anchor fitting is made up of the adapter plate 5 that is positioned at link-supporting plate 2 two ends and box-structure 1, in the fitting process, at first weld adapter plate 5 and box-structures 1 according to the length of link-supporting plate 2 at upper cover plate 3, end with link-supporting plate 2 is inserted in the box-structure 1 then, spacing with box-structure 1, it is fixing by bearing pin 4 that the other end snaps onto adapter plate 5 backs.
As improvement of the present utility model, the end that described link-supporting plate 2 inserts box-structure 1 is wedge shape.Wedge shape can play good directional tagging, and dismounting is more convenient efficient.
Original bolt fixed mode in installation process, need carry out fastening to a plurality of bolts with impact wrench, also be difficult to dismounting during replacing, comparatively speaking, this structure that the utility model adopts has improved the efficient of assembling greatly, reduce the dismounting difficulty, be more conducive to dismounting and change.
