Abstract
The utility model discloses a semi-trailed van. The skeletons of the both side walls of a van body serve as the skeletons of the edge beams for the load bearing of the integral van. Each skeleton is a grate bar frame-shaped skeleton, and is composed of more than two edge beams of rectangular cross section steel and a vertical column of groove-shaped steel. The edge beams and the vertical column are welded. The wheel assembly of the van is installed on two longitudinal rear end beams which are arranged at the rear part of a van body to form a construction with a sufficiently large factor, which reachesthe requirements on bearing strength and bearing rigidity. The utility model omits two longitudinal beams of the original frame with the advantages of material saving, the reduction of weight of the van, the reduction of production cost, and the simplification of manufacture process.
Description
The utility model discloses a kind of closed-type semitrailer, it belongs to operation Transport Machinery technical field.
Existing closed-type semitrailer generally has vehicle frame, container, towing pin, and supporting leg and wheel set are formed.Wherein vehicle frame is the weight of bearing whole superimposed trailer by the frame assembly that two elongated I-beam section longerons and several crossbeam constitute.This vehicle frame is because the specification of I-beam section longeron determines himself Heavy Weight at 240-340 (height) * 12-15 (thick), and consumptive material is many, account for car load heavy 25%.Moreover the planimetric position degree that vehicle frame and container connect requires the technology height, thereby caused the productive costs height, the manufacturing process trouble cover end.
The purpose of this utility model is the end that covers that will overcome above-mentioned superimposed trailer.Design a kind of closed-type semitrailer, this car bears the load-carrying capacity of car load with enough strong envelope.Require under the prerequisite at the strength and stiffness that satisfy carrying, simplified manufacturing technique is saved steel, improves stock utilization, alleviates the superimposed trailer deadweight.
Task of the present utility model has following technical scheme to finish, developed a kind of closed-type semitrailer, it comprises the compartment that has inside and outside shell skin and side, back door, be located at the traction pin of front end at the bottom of the railway carriage or compartment, be located at the wheel set at rear portion at the bottom of the railway carriage or compartment, be located at the supporting leg of front portion at the bottom of the railway carriage or compartment, the two side skeleton that constitutes the compartment is a side bar and the vertical column of arranging orderly flute profile steel by the rectangular cross section steel more than two as the side bar skeleton of car load carrying, by the grid frame shape skeleton that is welded; The compartment top that constitutes the compartment then is welded between the relative top side rail both sides with horizontal purlin post; Then be welded on the skirt member bottom surface at the bottom of the railway carriage or compartment in formation compartment with the horizontal bottom cross beam supporting of flute profile steel; The antetheca that constitutes the compartment then is welded between the horizontal purlin post and horizontal bottom cross beam of compartment front end with vertical column; On the bottom cross beam bottom surface at rear portion at the bottom of the railway carriage or compartment, also be welded with the end carriage of back longitudinally of two rectangular cross section steel, be welded with the suspension holdfast of wheel set below this end carriage.
This closed-type semitrailer, described two side skeleton can also be set up modified scissors truss in its grid frame shape skeleton, and this truss is welded on the diagonal line place of top, skirt member.
This closed-type semitrailer, described back end carriage, the suspension holdfast number that it welds below is increased to 4 with the increase of the wheel number of axle by 2, and the length of rear end frame also increases thereupon, thereby constitutes single shaft, twin shaft, three wheel set.
This closed-type semitrailer, the side bar of described rectangular cross section steel or back end carriage, its optimum dimension is: wide * height * thick=50 * 100 * 3-5mm; The purlin post of described flute profile steel or column or crossbeam, its optimum dimension is: wide * height * thick=50 * 100 * 3mm.
Closed-type semitrailer of the present utility model, its advantage is: because the skeleton structure in compartment is as the agent structure of car load carrying, this structure has enough strength and stiffness, thereby can save two longerons of former vehicle frame, steel have been saved, simplify manufacturing process, improved stock utilization, alleviated the deadweight of superimposed trailer.Because the two side in compartment and the formation one compartment of railway carriage or compartment bottom cross beam thereof, vehicle frame and container become one, and the planimetric position degree of the two connection is consistent, can reach fully to make the mounting process requirement, and simplify manufacturing process.
The utility model embodiment further describes as follows in conjunction with the accompanying drawings:
Fig. 1 cuts open constructional drawing for the railroad car lateral wall office of closed-type semitrailer.
Fig. 2 is railway carriage or compartment, the compartment bear building-up composition of closed-type semitrailer, (the A-A view of Fig. 1).
Fig. 3 is the compartment antetheca constructional drawing of closed-type semitrailer.
Fig. 4 is the whole car shape scheme drawing of closed-type semitrailer.
The closed-type semitrailer of a 15-25 ton of making.As shown in Figure 4.Its vehicle body is long: 12200mm, overall height: 3720mm, overall width: 2320mm, wherein supporting leg 10 is located at front portion at the bottom of the railway carriage or compartment, traction pin 6 is located at front end 1200mm place at the bottom of the railway carriage or compartment, incrustation is that the iron sheet of 1.0mm muscle with ribbing is welded on the Vehicle body skeleton, and wheel set 9 is the twin axle assembly, and this assembly 9 is installed on the end carriage 8 of back.The compartment rear wall is the railway carriage or compartment door, adopts the 1AA type container-type railway carriage or compartment door of iso standard.This semi-mounted car owner characteristics are: constitute the side bar skeleton of the two side skeleton in compartment as the car load carrying.As shown in Figure 1 and Figure 2, this skeleton is by the side bar 2 of the three rectangular cross section steel vertical column 3 orderly with arrangement, by the grid frame shape skeleton that is welded.This skeleton also between top, skirt member, is set up modified scissors truss 5 for strengthening the strength and stiffness of body structure in 4 vertical columns intervals, this truss 5 is welded on the diagonal line place of top, skirt member 2.Then be welded on the bottom surface of skirt member 2 at the bottom of the railway carriage or compartment in compartment with horizontal bottom cross beam 4 supportings of flute profile steel.The end carriage 8 of back longitudinally that is welded with two rectangular cross section steel on the bottom surface of the bottom cross beam 4 at rear portion at the bottom of the railway carriage or compartment in compartment is as the strength beams that wheel sets 9 are installed.Be connected between this end carriage 8 and the wheel set 9 to be welded between the two and realize by suspension holdfast 7.Compartment top in the compartment then is welded between relative top side rail 2 both sides with horizontal purlin post 11.Antetheca in the compartment then is welded on vertical column 3 between the horizontal purlin post 11 and horizontal bottom cross beam 4 of compartment front end, as shown in Figure 3.Steel that this compartment adopts, the size model of its side bar 2 or back end carriage 8 is: 50 * 100 * 4mm; The size model of its column 3 or crossbeam 4 or purlin post 11 is: 50 * 100 * 3mm.
