Abstract
The utility model discloses an adjustable stand column handrail joint of a metro vehicle in order to solve the problems of poor appearance and high cost of a handrail caused by the existing handrail joint. The adjustable stand column handrail joint of the metro vehicle comprises a connecting sleeve fixedly connected with a stand column, the connecting sleeve is fixedly connected with a transverse handrail, and a structure for preventing the transverse handrail from rotating is arranged in the connecting sleeve. The handrail joint disclosed by the utility model is more convenient to assemble and disassemble, and has the function of large transverse adjustment, additional mould opening is not needed for the joint, the cost of a product is greatly reduced, the handrail joint has stronger generality, a mall size and light weight, the surface treatment mode of the handrail joint is the same as that of an ordinary stand column handrail, at the same time the installation adjustment function of the stand column handrail is realized, and the technological installation efficiency is greatly improved.
Description
Technical field
The utility model relates to interconnective a kind of adjustable joint between the railcar central post handrail.
Background technology
Used column handrail comprises column and horizontal handrail in subway or the light rail vehicle at present; Its material mainly contains two kinds of corrosion-resistant steel and aluminum alloys; Must lean on cast aluminium or cast steel jointing to carry out the horizontal installation adjustment of column handrail when the column handrail is installed, but cast aluminium jointing volume is bigger, the plastic-blasting surface processing mode of aluminum casting has determined that its surface lifetime is shorter simultaneously; Damage easily in the use, scratch, guest room in-to-in whole structure is had very big influence; And cast steel interface die sinking cost is higher, and the profile of its big volume, heaviness is serious to whole guest room influential effect equally.
Summary of the invention
Cause the deficiency that the handrail life-span is short or cost is high in order to overcome existing handrail joint; The utility model aims to provide a kind of railcar scalable column handrail joint; This scalable column handrail jointing is mainly used in the column handrail and the horizontal connecting portion of handrail in subway or the light rail vehicle; Can reduce the overall weight of handrail, make things convenient for process adjustments, and improve the installation effectiveness of column handrail and the whole structure of whole guest room.
To achieve these goals; The technical scheme that the utility model adopted is that said railcar scalable column handrail joint comprises the coupling bush of captiveing joint with column; This coupling bush is captiveed joint with horizontal handrail; Its constructional feature is to be provided with the structure that prevents horizontal handrail rotation in the said coupling bush.
As a kind of preferred version, the said structure that prevents that horizontal handrail from rotating is to be arranged on the groove that matches with horizontal handrail termination in the coupling bush.
As a kind of scheme, column is connected with horizontal handrail for ease, and said column one side is provided with fixed muffle, and this column opposite side is provided with said coupling bush; Be fixed together through tie bolt between said fixed muffle, column, coupling bush and the horizontal handrail.
Further, for many root posts and horizontal handrail bonded assembly situation, said fixed muffle links to each other with another horizontal handrail, so just can all columns and horizontal handrail be together in series through the handrail joint.
Said coupling bush and fixed muffle coaxial line can guarantee that all horizontal handrails are on same straight line.
By said structure, the handrail caliber in the railcar has standard-required, generally between φ 30 to φ 40, no matter adopts great caliber design, and the technical scheme of below introducing can be carried out accommodation according to selected caliber.Below be that the column of φ 38 and horizontal handrail that caliber is φ 32 are connected to example and describe with the caliber.The utility model scalable column handrail jointing all adopts stainless steel, adopts the stainless steel tube (sleeve uses for the horizontal handrail of pegging graft) of φ 35x1.5 with column two sleeves welded together, and attachment bolt adopts the stainless steel of M12; One of them sleeve inner has the groove that prevents that horizontal handrail from rotating; The boss of this groove and horizontal handrail termination is used; After the horizontal handrail with groove fit snaps in the groove, should fix by horizontal handrail through the binding bolt of M12 again, can prevent that on the one hand the passenger from holding up that horizontal handrail circumferentially rotates in the process grabbing; The play that horizontal handrail is horizontal can be prevented on the other hand, the bulk strength of structure can be guaranteed like this; Use the connecting joint of this mode both can guarantee the whole structure that the guest room is attractive in appearance, generous, can make whole erection dismounting technology easier again, have laterally regulatory function on a large scale simultaneously.
Compared with prior art, the beneficial effect of the utility model is: adopt the scalable column handrail jointing installing/dismounting of the utility model more convenient, long service life; Have the lateral adjustments function, concrete adjusting numerical value is along with the length of sleeve increases and increases, and joint processes for the standard stainless steel tube; Need not extra die sinking, lowered cost of product greatly, and have stronger commonality; Its volume is little, in light weight, and surface treatment mode is identical with common column handrail, makes whole guest room elegant in appearance; Realize the install adjustment function of column handrail, improved process Installation efficient greatly.
Below in conjunction with accompanying drawing and embodiment the utility model is done further to set forth.

The 1-coupling bush; The 2-column; The 3-tie bolt; The 4-fixed muffle; The 5-groove.
The specific embodiment
A kind of railcar scalable column handrail joint shown in Fig. 1 ~ 3, comprises the stainless steel band anti-rotation groove coupling bush 1 of φ 35x1.5, the corrosion-resistant steel column 2 of φ 38, the corrosion-resistant steel tie bolt 3 of M12, the corrosion-resistant steel fixed muffle 4 of φ 35x1.5.Wherein coupling bush 1 is that stainless steel tube by φ 35x1.5 processes, and interior welds has the rotation-prevention draw-in groove, and concrete size can be determined by setting range; The concrete length of corrosion-resistant steel column 2 confirms that according to the height of guest room its position of opening is confirmed by horizontal handrail by car load.
When handrail is installed; The first step; " the stainless steel band anti-rotation groove coupling bush 1 of φ 35x1.5 " and " the corrosion-resistant steel fixed muffle 4 of φ 35x1.5 " is welded on " the corrosion-resistant steel column 2 of φ 38 "; Must guarantee the straightness accuracy requirement of coupling bush 1 and fixed muffle 4 after welding is accomplished, guarantee that promptly coupling bush 1 is consistent with fixed muffle 4 line of centerss.In second step, the horizontal handrail that will have the anti-rotation boss is inserted in the coupling bush 1 that has the anti-rotation groove, and from the other end that horizontal handrail tension is fastening through " the corrosion-resistant steel tie bolt 3 of M12 ".And the like, the horizontal handrail of another one is inserted in the fixed muffle 4 of opposite side the same first step of the Connection Step of this horizontal handrail other end; Repeat above institute so in steps, but the column handrail of accomplishing the whole guest room of railcar at short notice of simple and fast is installed.
The content that the foregoing description is illustrated is to be understood that to these embodiment and only is used to be illustrated more clearly in the utility model; And be not used in the restriction the utility model scope; After having read the utility model, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the utility model.
