Description

Hinge type folding cover plate

Technical Field

The utility model relates to an apron, especially a hinge type folding cover plate.

Background

The conventional safe and labor-saving cover plate main body consists of a frame and two bottom plates, and the opening height of the bottom plates is more than 1200 mm; however, for a large object hanging hole, the lifting operation of workers can be affected by the fact that the base plate of the conventional cover plate is too high in opening height in a production field, and the opening of the fence is time-consuming and labor-consuming and has unsafe factors. To the large size apron, also there are 2 bottom plates to connect through the connecting axle among the current device, realize folding, make and open the height and can not be too high, but because structural existence is not enough, it is very hard when using the connecting axle to realize folding apron pulling, and the pull-up impact force is very big after coming, damage the apron very easily, and influence the life of apron very much, and difficult control in the apron motion process, consequently, how to improve and the innovation to the structure of current folding apron, in order to satisfy current demand, be the technical problem who needs to solve urgently.

SUMMERY OF THE UTILITY MODEL

To the above situation, for overcoming the defects of the prior art, the utility model aims at providing a hinge type folding cover plate, which can effectively solve the problems that the existing cover plate is too high in opening height, the folding cover plate is hard to pull, the impact force is large after the folding cover plate is pulled up, and the cover plate is easy to damage.

In order to achieve the purpose, the utility model provides a technical scheme is, a hinge type folding cover plate, including bottom plate and hinge means, the bottom plate be equipped with adjacent a plurality ofly, hinge means all is equipped with between two adjacent bottom plates, hinge means include the articulated elements that two meshing are connected, first connecting plate is all equipped with to the articulated elements both sides, the articulated shaft on the articulated elements is together fixed with the first connecting plate of both sides through the bearing, constitutes the articulated beta structure between adjacent bottom plates.

The utility model discloses simple structure, easy manufacturing, convenient operation has solved the difficult problem of great apron folding bottom plate switching, and the wide applicability has apparent society and economic benefits.

Detailed Description

The following detailed description of the embodiments of the invention is provided in connection with the accompanying drawings and the detailed description.

The hinge type folding cover plate comprises bottom plates and hinge devices, wherein the bottom plates 1 are provided with a plurality of adjacent bottom plates, the hinge devices 2 are arranged between every two adjacent bottom plates 1, each hinge device 2 comprises two hinged pieces which are connected in a meshed mode, first connecting plates 6 are arranged on two sides of each hinged piece, and hinged shafts 5 on the hinged pieces are fixed with the first connecting plates 6 on the two sides through bearings 7 to form a hinged folding structure between the adjacent bottom plates.

To ensure a better working performance, the bottom plate 1 is provided with at least 2 (only 2 are shown in the figure).

Articulated elements include gear seat 3, gear 4 and articulated

shaft

5, 3 symmetrical arrangement of 2 gear seats, all be equipped with gear 4 through articulated shaft 5 in 2

gear seats

3, 2 gear 4 meshing links together, articulated shaft 5 dress is in the centre bore of

gear

4, 5 both ends of articulated shaft stretch out gear seat 3 and fix together through bearing 7 and first connecting plate 6.

Gear seat 3 include two polygon flat plates 301 and second connecting plate 302, two polygon flat plates 301 that parallel was opened mutually constitute an organic whole structure through second connecting plate 302 welding together, be equipped with horizontal articulated shaft 5 on the polygon flat plate 301, be located 2 polygon flat plate 301 in articulated shaft 5 be equipped with

gear

4, 3 sides of gear seat and bottom plate 1 welding together.

The utility model discloses when specifically using, as shown in fig. 1, 3 side welding of 2 gear seats are between adjacent bottom plate 1, adjacent bottom plate 1 is folded and is opened through hinge means 2, in folding process, the pulling bottom plate, 2 gear 4 meshes the rotation, drive 2 hinge means 2 synchronous rotations through articulated shaft 5, bearing 7 and the cooperation of hinge shaft 5, rely on the rolling contact between the component to support transmission part, the resistance in the motion process has been reduced, the precision of gyration has been guaranteed, through gear drive, it is steady accurate in the motion process, instantaneous drive ratio keeps unchangeable, impact force when having avoided starting, make the bottom plate light, fold together steadily, hinge means 2 when folding together is shown in fig. 6.

The utility model discloses simple structure, the easy manufacturing, convenient operation has solved the difficult problem of great apron folding bottom plate switching, and the apron is opened highly suitably, and the pulling is not hard, has improved work efficiency, and folding process is steady, and the impact force is little, and not fragile apron has prolonged the life of apron, and the application is wide, through using on the spot, has come into use in places such as the thermal power station of many places, power station, and the effect is very good, has apparent society and economic benefits.
