Abstract
A loader engine hood relates to the technical field of engineering machinery, and is characterized in that a portal frame and a rear hood assembly are mutually connected to form the loader engine hood, the rear hood assembly comprises a hood body located at the top, large side doors on two sides and a rear door, the large side doors on the two sides are hinged with the hood body at the top through pin shafts and can be outwards opened along hinged positions, and the portal frame, the hood body and the large side doors all adopt structures of welding coverings onto frameworks. The loader engine hood has the advantages that the loader engine hood is fine in structural strength, low in cost and convenient in assembly, and a wide maintenance space can be exposed after the large side doors are opened outwards, thereby bringing convenience for daily maintenance of the engine.
Description
Technical field
The utility model relates to technical field of engineering machinery, especially a kind of loader hood.
Background technology
At present, the hood of domestic loader can be divided into monolithic and split type two kinds by its structure, wherein, its unfolding mode of all-in-one-piece hood is integral body lifting backward, lifting power comes from electronic lifting or hand lifting, the lifting motor that electronic lifting is used costs an arm and a leg, easy-maintaining not after the damage, maintenance cost height; Hand lifting relative cost is lower, but the efficient of lifting is also low, increases operator's labour intensity; Split type hood is lower than monolithic hood cost, but split type hood is assembled on line by a plurality of component, and is lower than the efficiency of assembling of monolithic hood on complete machine.
Summary of the invention
It is low that the purpose of this utility model just provides a kind of cost, is convenient to assembling, is convenient to the loader hood of on-wing maintenance.
Solution of the present utility model is such: interconnected by portal frame and back cover assembly and form, described back cover assembly includes the cover body that is positioned at the top, the big side door of both sides, little side door and back door, the big side door of both sides is hinged by the cover body at bearing pin and top, little side door is connected with cover body by hinge, when needs are opened hood motor are carried out regular maintenance, big side door is outwards opened along the hinged place, can be exposed broad service clearance.
In such scheme, the pin joint of described big side door and cover body can be at top and unilateral copulation place, can be connected with air spring between big side door and the cover body; Described air spring can be installed in big side door open angle in 45 ° of-110 ° of scopes; The external surface of described big side door can be covering, is connected with skeleton in the inboard of covering; Lower end at described big side door can be equipped with door bolt; Inner peripheral at described big side door can be equipped with damping glue; Little side door can be equipped with damping glue and set lever on the inboard.
The utility model has the advantages that: 1, portal frame, cover body, big side door all are the welded constructions that the employing skeleton adds covering, low cost of manufacture, and structural strength is good; 2, after portal frame and back cover assembly assemble, directly lift on the complete machine, the bolt of screwing on can be finished installation, improves the following linear velocity of final assembly greatly; 3, when needs are opened hood motor are carried out regular maintenance, only need pull the door lock on the big side door gently, big side door is opened under the elastic force effect of air spring automatically, expose broad service clearance, after finishing maintenance,, make the air spring compression as long as one pulls the moving handle that is installed on the big side door, side door is pressed in another have gentle hands, plate snap close on the door is tightly got final product, and whole process operation is simple, without lifting an eyebrow.

The specific embodiment
Embodiment of the present utility model includes portal frame 1, back cover assembly 2, and back cover assembly 2 comprises cover body 3, back door 4, door lock 5, little side door 6, big side door 7, handle 8, air spring 9, snap close 10, damping glue 11, bearing pin 12, set lever (13).
In structure shown in Figure 1, portal frame 1 and back cover assembly 2 fuse, and big side door 7 closures are by door lock 5 and snap close 10 lockings; Open door lock 5 this moment, gently widens side door 7, and big side door 7 upwards turns under the elastic force effect of air spring 9 automatically, have air spring 9 to support and expose roomy service clearance, if needed, set lever 13 fastenedly, little side door 6 is opened, exposed broader service clearance, as Fig. 2, shown in Figure 3.
