Abstract
The utility model belongs to field of road engineering machinery, is specifically related to a kind of digger hood bob opening mechanism.Comprise hood, in the rear wall of hood, lower end is provided with air spring, and the included angle B of air spring and horizontal direction is 12 °, door handle is provided with in the middle part of the forearm of hood, the bottom of door handle is connected with pull bar, and the lower end of pull bar is provided with door lock, and the forearm lower end of hood is welded with hook.The angle of air spring of the present utility model and horizontal direction is 12 °, so can reduce air spring component upwards nearly 50%, and when opening hood, the gravity of air spring component upwards and hood is more or less the same, laborsaving during unlatching; Opening mechanism of the present utility model changed door lock type into by former drag-line, and hood is welded with hook, and when outwards pulling door handle, pull bar pulls the locking plate in door lock to rotate up, and the locking plate be stuck on hook cross bar screws out, and hood is opened time saving and energy saving.
Description
Technical field
The utility model belongs to field of road engineering machinery, is specifically related to a kind of digger hood bob opening mechanism.
Background technology
Along with excavator industrial expansion, excavator power is increasing in recent years, and hood is also thereupon increasing, more and more longer.
Existing digger hood bob as shown in Figure 1, be made up of hood 1, air spring 2, lock ring support 3, snap lock 4 and drag-line 5, there is following problem: 1. air spring position is unreasonable, the included angle A 6 of air spring and horizontal direction is 23 °, air spring separation is upwards caused to be far longer than the gravity of hood, to such an extent as to each all just to can open hood to a downward power when opening, when closing hood, overcome air spring component upwards could close; 2. drag-line opening device is unreasonable, when opening hood, opening stay cable must be moved by manual water horizontal drawing, drag-line drives snap lock to rotate backward, and after rotating to certain angle, snap lock just screws out from lock ring support, hood could be opened, because opening stay cable is loaded on instrument calibration, make drag-line longer, frictional resistance is larger.
Utility model content
For the deficiency that prior art exists, the digger hood bob opening mechanism that the utility model provides a kind of structure simple, easy to operate, time saving and energy saving.
The utility model is achieved through the following technical solutions:
A kind of digger hood bob opening mechanism, comprise hood, in the rear wall of described hood, lower end is provided with air spring, the included angle B of described air spring and horizontal direction is 12 °, door handle is provided with in the middle part of the forearm of described hood, the bottom of described door handle is connected with pull bar, and the lower end of described pull bar is provided with door lock, and the forearm lower end of described hood is welded with hook.
Further, the cross bar of described hook and the locking plate phase clamping of described door lock.
Compared with prior art, the beneficial effects of the utility model are:
1, the angle of air spring of the present utility model and horizontal direction is 12 °, so can reduce air spring component upwards nearly 50%, and when opening hood, the gravity of air spring component upwards and hood is more or less the same, laborsaving during unlatching;
2, opening mechanism of the present utility model changed door lock type into by former drag-line, and hood is welded with hook, and when outwards pulling door handle, pull bar pulls the locking plate in door lock to rotate up, and the locking plate be stuck on hook cross bar screws out, and hood is opened time saving and energy saving;
3, the utility model is all adopt on-the-spot component to make, and cost of production is not high; And structure is simple, easy to operate, is beneficial to and extensively promotes the use of.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model prior art;
Fig. 2 is structural representation of the present utility model.
In accompanying drawing 1: 1. hood; 2. air spring; 3. lock ring support; 4. snap lock; 5. drag-line; 6. included angle A; 7. door handle; 8. pull bar; 9. door lock; 10. link up with; 11. included angle B.
Detailed description of the invention
A kind of digger hood bob opening mechanism, comprise hood 1, in the rear wall of hood 1, lower end is provided with air spring 2, air spring 2 is 12 ° with the included angle B 11 of horizontal direction, door handle 7 is provided with in the middle part of the forearm of hood 1, the bottom of door handle 7 is connected with pull bar 8, and the lower end of pull bar 8 is provided with door lock 9, and the forearm lower end of hood 1 is welded with hook 10.
Further, the cross bar of 10 and the locking plate phase clamping of door lock 9 is linked up with.
Adopt hood opening mechanism of the present utility model, as long as slightly to pulling door handle outward, hood just can be opened, and air spring is not easy to lose efficacy, and efficiently solves digger hood bob and opens the problem wasted time and energy.
To sum up, be only preferred embodiment of the present utility model, not be used for limit the utility model implement scope, all shapes according to the utility model right, structure, feature and spirit do equalization change with modify, all should be included in right of the present utility model.
Claims (2)
