Abstract
The utility model discloses a construction machinery cabin top cap overlap joint structure, including two A posts, two outer coverings of A post, two A column holders and ceiling, the both sides at driver's cabin front windshield are installed to two A post symmetries, two A column holders weld the upside with two A posts respectively, the side of ceiling welds the last plane at two A column holders along length direction respectively along the last border with the outer covering of two A posts. The utility model discloses be applied to the excavator driver's cabin, not only simplified excavator driver's cabin skeleton texture, reduced manufacturing cost, guaranteed simultaneously the intensity of skeleton framework to driver's safety has been guaranteed.
Description
Technical field
This utility model is related to engineering machinery field and in particular to a kind of engineering machinery driving cabin top cover bridging arrangement.
Background technology
With the progressively popularization of excavator, people constantly deepen to the understanding of excavator, to the safety of excavator, attractive in appearance
Property require more and more higher.Because the construction environment of excavator is general relatively more severe, therefore excavator cab is as the master of driver
Want working region, the intensity of its internal structure has particularly important meaning in terms of ensureing driver's personal safety.
At present, for meeting the anti-tipping intensity requirement of ROPS or TOPS, the main skeleton of excavator cab is by sheet metal structural
It is changed to profile shapes structure, because profile shapes making moulding process is more difficult, structure also unsuitable too complex, this allows for top cover
Overlap joint has some limitations.
There are following two aspects in existing framing structure：
1. framing structure is relatively simple, and top cover overlap joint is not compact, attractive in appearance, and intensity is not enough；
2. framing structure is complex, though intensity and appearance requirement can be reached, moulding process difficulty is big, yield rate
Low, expense is of a relatively high, therefore increased production cost.
Utility model content
For solving the deficiency that prior art exists, the utility model discloses a kind of engineering machinery driving cabin top cover overlap joint knot
Structure, is applied to the overlap joint of lid of cab structure.The system is reasonable in design and bonding strength is high, has good looking appearance, overlap joint tightly
Gather, the advantages of moulding process is simple, greatly improves yield rate, saved production cost.
For achieving the above object, concrete scheme of the present utility model is as follows：
A kind of engineering machinery driving cabin top cover bridging arrangement, including two A posts, two A post exterior skins, two A column holders
And ceiling, described two A column symmetry are arranged on the both sides of driver's cabin front windshield, described two A column holders be respectively welded in
The upside of two A posts, the side edge of described ceiling and the upper edge of two A post exterior skins are respectively along the length side of described A column holder
To the upper plane being welded on two A column holders.
Further, the cross section of described A column holder is the U-shaped of handstand.
The beneficial effects of the utility model：
A spinous process of the seventh cervical vertebra frame of the present utility model is made up of A post and A column holder two parts, and A spinous process of the seventh cervical vertebra frame not only can be made real with ceiling
The rational Matching Relation of existing effect, the intensity improving A spinous process of the seventh cervical vertebra frame is it is ensured that the safety of driver；Also ensure that and cover with outside type A post
While the appearance requirement of skin, simplify the moulding process of A post profile shapes, improve yield rate, thus effectively reducing
Production cost.

Specific embodiment：
Below in conjunction with the accompanying drawings this utility model is described in detail：
As shown in Figures 1 and 2, a kind of engineering machinery driving cabin top cover bridging arrangement, including 1, two A posts of two A posts outside
2, two A column holders 3 of eyelid covering and ceiling 4, described two A posts 1 are separately mounted to the both sides of driver's cabin front windshield, and described two
Individual A column holder 3 is respectively welded in the upside of two A posts 1, and the side of described ceiling 4 divides along the upper edge with two A post exterior skins 2
It is not welded on the upper plane of two A column holders 3 along the length direction of described A column holder 3.
As shown in Figures 3 and 4, the cross section of described A column holder 3 is the U-shaped of handstand.
Although the above-mentioned accompanying drawing that combines is described to specific embodiment of the present utility model, not new to this practicality
The restriction of type protection domain, one of ordinary skill in the art should be understood that on the basis of the technical solution of the utility model, ability
Field technique personnel do not need to pay the various modifications that creative work can make or deformation still in protection model of the present utility model
Within enclosing.
