Abstract
The utility model discloses a supporting cylinder, and the cylindrical wall of the supporting cylinder adopts a corrugated structure. The structural form of the cylindrical wall is changed, and the corrugated cylindrical wall is used for replacing a traditional cylinder, the corrugated cylindrical wall is curved in appearance, reinforcing ribs are added equivalently, the self-weight of the structure can be reduced, the safety and the reliability of structural parts are improved, and the bearing performance is improved. The utility model further discloses a crane comprising the supporting cylinder.
Description
Technical field
The utility model relates to bracing or strutting arrangement technical field, relates in particular to a kind of hoisting crane and support tube thereof.
Background technology
Span winch is port and pier quantity and uses maximum, complex structure, maximum, the most typical electronic loading-unload machines of mechanism.
In kind, span winch can be divided into rotary-column type span winch, fixed column type span winch, rotating disc type span winch and large bearing-type span winch.In structure, span winch is divided into top rotating part and bottom operation part.Top rotating part generally supports by columnar upright supports cylinder.
In addition, the column of maintenance crane is also to adopt the support tube of cylindrical structure to support.Support tube bears vertical pressure and capsizing moment.But the support tube adopting is at present cylinder planomural, conducts oneself with dignity larger, and load-carrying properties are poor.
Therefore, how providing a kind of support tube, to improve load-carrying capacity, is current those skilled in the art technical matterss urgently to be resolved hurrily.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of support tube, to improve load-carrying capacity.Another object of the present utility model is to provide a kind of hoisting crane that comprises above-mentioned support tube.
In order to achieve the above object, the utility model provides following technical scheme:
A support tube, its barrel is ripple struction.
Preferably, above-mentioned support tube is to be welded after corrugated plating encloses.
Preferably, above-mentioned support tube is roll forming.
The utility model also provides a kind of hoisting crane, comprises support tube, and described support tube is the support tube as described in the claims 1-3 any one.
Preferably, above-mentioned hoisting crane is span winch.
Preferably, above-mentioned hoisting crane is maintenance crane.
The support tube that the utility model provides, its barrel is ripple struction.By changing the version of barrel, with the barrel of bellows-shaped, replace conventional cylinder, the barrel of this bellows-shaped is curve outward appearance, be equivalent to increase reinforced rib, can alleviate dead load, increase the safe reliability of framing member, improve load-carrying properties.
Accompanying drawing explanation
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 embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The plan structure schematic diagram of the support tube that Fig. 1 provides for the utility model embodiment.
In upper Fig. 1:
Barrel 1.
The specific embodiment
For making object, technical scheme and the advantage of the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills 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, the plan structure schematic diagram of the support tube that Fig. 1 provides for the utility model embodiment.
The support tube that the utility model embodiment provides, its barrel 1 is ripple struction.By changing the version of barrel 1, with the barrel 1 of bellows-shaped, replace conventional cylinder, the barrel 1 of this bellows-shaped is curve outward appearance, be equivalent to increase reinforced rib, can alleviate dead load, increase the safe reliability of framing member, improve load-carrying properties.
And, on ripple struction, ripple wavelength and wave height are that cross-sectional plane along with support tube varies in size and different, have a plurality of ripples on ripple struction, and the wave height of these ripples and wavelength should be identical, can make integral body bear uniformly pressure, tender consolidation further improves load-carrying properties.
Wherein, above-mentioned support tube can be welded after enclosing for corrugated plating, can be also roll forming.
The utility model embodiment also provides a kind of hoisting crane, comprises support tube, and support tube is the support tube of embodiment as described in above-mentioned any one, can improve load-carrying properties.Wherein, above-mentioned hoisting crane can be span winch, can be also maintenance crane.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the utility model.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
Claims (4)
1. a support tube, is characterized in that, its barrel is ripple struction, and support tube is to be welded after corrugated plating encloses or is roll forming.
2. a hoisting crane, comprises support tube, it is characterized in that, described support tube is as above-mentioned support tube claimed in claim 1.
3. hoisting crane according to claim 2, is characterized in that, is span winch.
4. hoisting crane according to claim 2, is characterized in that, is maintenance crane.
