At above-mentioned one Malaysia flatcar protection railing device, handrail composition plug position, bottom is welded with a back-up ring, and back-up ring bottom is insertion portion, just inserts completely when back-up ring drops on back bar on socket.
At above-mentioned one Malaysia flatcar protection railing device, also comprise a latch composition, described latch composition comprises latch and corrosion-resistant steel chain link; One end and the latch stub end of chain link are fixed, and the other end of chain link uses M4 to be bolted on one of them support plate of socket composition; The hole connected is opened at described socket middle part and corresponding handrail position of inserting, and latch adopts stainless steel band hole round pin, and nose end inserts a β type spring cotter.
At above-mentioned one Malaysia flatcar protection railing device, the large 2mm of the pipe external diameter that the stainless steel tube internal diameter of socket composition forms than handrail.
Therefore, the utility model tool has the following advantages: 1. reasonable in design, and structure is simply and completely practical; 2. often organize railing can extract in 1 minute and insert.Frock ensure that each group of socket composition relative position is consistent, and threeway, four-way and root of Dahurian angelica plate slotted hole ensure that handrail assembling process can match with socket, so lateral rail has interchangeability.Handrail socket and handrail gap less, the overall shaking volume of railing is less, does not substantially produce noise, the lateral rail top after actual measurement assembling at cross travel between 5mm ~ 15mm.Handrail and female contact sections adopt stainless steel, effectively prevent peeling paint and corrode.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 is the partial enlargement structural representation at A place in Fig. 1.
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Detailed description of the invention:
As shown in Figure 1, be the schematic diagram of railing composition, the utility model comprises four parts, and handrail composition 1, the root of Dahurian angelica plate be fixed on below handrail composition form 2, are fixed on outside Malaysian flatcar for the socket composition 3 of fixed armrest composition and latch composition 4; Wherein socket composition coordinates corresponding frock, both the handrail composition assembled in advance, requires that the strict demands such as each horizontal longitudinal size, planeness differ with drawing and is less than 1mm, as frock, be positioned on car body floor, socket is inserted the conformability that frock spot welding both can ensure each group of socket.Complete coating paint with truck body after welding socket, other parts are all first paint to assemble again, and each position is connected by bolt.
Each single handrail and threeway four-way are inserted socket, adjusts assembling threeway and four-way after railing position and integral planar degree.Then assemble root of Dahurian angelica plate, due to the regulating action of slotted hole horizontal on slotted hole vertical on handrail and root of Dahurian angelica plate, make the bolt connecting root of Dahurian angelica plate and handrail assemble more convenient.Then latch composition bolt is connected on socket, wherein after bolt tightening the bolt straight section bending outside nut, prevent bolt falling.
Lower mask body introduces the concrete structure of each component part.
1, handrail composition.
Handrail is divided into some sections, and outmost turns is divided into two sections of 90 ° of bending tubes, and inner vertical two steel pipe not segmentations, intermediate lateral pipe is divided into three sections.Each joint adopts threeway to be connected with four-way, and each steel pipe puts in threeway or four-way depth adjustable joint, and this method energy actv. ensures the adjustment of each lower end intercalation part column pitch, makes four plug alignment sockets.
Handrail on lower side each plug position is welded with a back-up ring 6, and just insert completely when back-up ring 6 drops on back bar on socket, back-up ring 6 bottom is insertion portion.
2, root of Dahurian angelica plate composition.
Root of Dahurian angelica plate is the corral plate above floor bottom railing, can prevent people from stepping on small articles in bulk on sky or car and drop, but can not bear the quick washing of large parts.Root of Dahurian angelica plate be by 3mm steel plate surrounding in the same way bending 30mm form, not only add root of Dahurian angelica panel stiffness but also seem more attractive in appearance.
Root of Dahurian angelica plate and handrail adopt M6 bolt to be connected, and each railing composition has 8 point of connection, and for meeting the adjustable requirement of handrail all directions, the bolt hole on root of Dahurian angelica plate is horizontal slotted hole, and the bolt hole on handrail is vertical slotted hole.Bolt and handrail contact surface adopt special U-shaped packing ring, adopt the especially big packing ring of GB 5287 with root of Dahurian angelica plate contact surface, can cover slotted hole by actv..
3, socket composition.
Often insert to prevent handrail or extract rear socket inwall peeling paint and corrode, socket is welded by the stainless steel tube of 0Cr18Ni9-42 × 2.5 and two pieces of support plates, integral solder (outside accessory is more, without space) inside side rail outer or end carriage again.Socket internal diameter 2mm larger than handrail (corrosion-resistant steel sleeve pipe) external diameter, length is 210mm, can meet handrail plug smoothly and run in the shaking volume requirement of handrail.Socket External view is shown in Fig. 2.
4, latch composition.
Vehicle constantly shakes in operational process, and handrail inserts socket and built on the sand, the socket therefore outside each handrail two devises latch composition, in case railing comes off in running.
The hole of the Φ 8mm connected is opened in socket middle part and corresponding handrail position of inserting, it is that 6mm is with hole round pin that latch 7 adopts material to be the corrosion-resistant steel diameter of 0Cr18Ni9, nose end inserts a β type spring cotter, stub end 8 is welded on corrosion-resistant steel chain link 5, and the other end of chain link uses M4 to be bolted to the support plate of socket.
After railing inserts socket, check whether each latch and β type spring cotter are plugged, extract railing and also will notice that the β type spring cotter dismantled will load in round pin in time, with anti-lost, even if careless loss is also easy to configure this kind of gauge member.By the auto-lock function of β type spring cotter, railing both can be made to be stabilized on car body, reduce vibrations, and " fast " dismounting of customer requirement can have been realized again and load railing.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
Although more employ the terms such as handrail composition 1, root of Dahurian angelica plate composition 2, socket composition 3, latch composition 4, corrosion-resistant steel chain link 5, back-up ring 6, latch 7, stub end 8 herein, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present utility model more easily; The restriction that they are construed to any one additional is all contrary with the utility model spirit.
