Therefore, how to solve the easy damage of manhole ladder and commonality and the poor problem of interchangeability in prior art, become those skilled in the art's important technological problems to be solved.
Utility model content
The utility model provides a kind of manhole ladder of tank car, and it can avoid causing because of tank body distortion the damage of manhole ladder, and its commonality and interchangeability better.The utility model also provides a kind of tank car that comprises above-mentioned manhole ladder.
The manhole ladder of a kind of tank car that the utility model provides, the main body of described manhole ladder divides ladder head and the tail to be formed by connecting by multistage, and two sections of points of ladders of arbitrary neighborhood are connected rotationally by rotating shaft.
Preferably, described point of ladder is two sections, and two sections of points of ladders are connected together rotationally by rotating shaft.
Preferably, point ladder described in two sections of arbitrary neighborhood, described in one of them, a point terraced end is provided with U-shaped Connection Block, and described in another, a point ladder is inserted in described U-shaped Connection Block and is connected with described U-shaped Connection Block by rotating shaft.
The utility model also provides a kind of tank car, comprises tank body, is provided with the manhole ladder described in as above any one in described tank body.
Preferably, the two ends of described manhole ladder are welded in respectively described tank body.
Preferably, described manhole ladder is provided with welding base, and described welding base is welded in described tank body, and the two ends of the main body of described manhole ladder are articulated with respectively described welding base.
The manhole ladder of a kind of tank car that the utility model provides, the main body of described manhole ladder divides ladder head and the tail to be formed by connecting by multistage, and two sections of points of ladders of arbitrary neighborhood are connected rotationally by rotating shaft.So arrange, due to the manhole ladder that the utility model provides, divide ladder to be connected to form rotationally by multistage, in the time of tank body generation deformation, can force multistage to divide ladder to rotate around the shaft, make the whole height of manhole ladder that corresponding change occur, and then the problem of having avoided manhole ladder to damage.In addition, the manhole ladder height providing due to the utility model can change, and then goes in different tank bodies, has the commonality and the interchangeability that have added.
The utility model also provides a kind of tank car that comprises above-mentioned manhole ladder, so arranges, and the manhole ladder of this tank car can be avoided the impaired problem of distortion because of tank body, and the manhole ladder of tank car inside has good commonality and interchangeability.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the deformation schematic diagram that in the utility model detailed description of the invention, manhole ladder produces when tank body generation deformation;
Fig. 2 is point terraced connection structure schematic diagram in the utility model detailed description of the invention;
In Fig. 1 and Fig. 2:

Detailed description of the invention
This detailed description of the invention provides a kind of manhole ladder of tank car, and it can avoid causing because of tank body distortion the damage of manhole ladder, and its commonality and interchangeability better.This detailed description of the invention also provides a kind of tank car that comprises above-mentioned manhole ladder.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 1 and Fig. 2, the manhole ladder of a kind of tank car that this detailed description of the invention provides, the main body 11 of manhole ladder divides ladder 12 head and the tail to be formed by connecting by multistage, and two sections of points of ladders 12 of arbitrary neighborhood are connected rotationally by rotating shaft 13.
So arrange, due to the manhole ladder that this detailed description of the invention provides, divide ladder 12 to be connected to form rotationally by multistage, entirety is bar linkage structure as shown in Figure 1.
In the time of tank body generation deformation, can force multistage to divide ladder 12 13 to rotate around the shaft, make the whole height of manhole ladder that corresponding change occur, and then the problem of having avoided manhole ladder to damage.In addition, the manhole ladder height providing due to this detailed description of the invention can change, and then goes in different tank bodies, has the commonality and the interchangeability that have added.
