Description
Technical field
The present invention relates to a kind of rail road tank car traction and bolster device with beam structure, the tank car of no underframe belongs to railway transportation equipment.
Background technology
At present, China does not have the underframe tank car and mainly is made up of tank body and pillow pulling device, utilizes the rigidity of tank body self, intensity to replace underframe.The pillow pulling device is welded in the tank body two ends respectively, is used for transmitting longitudinal force and vertical force, and its pillow pulling device is mainly assemblied by sleeper beam assembling and draw beam.Adopt the tank car of this structure, under Lognitudinal Impact of Trains compression force operating mode, the stress of its tank body tank shell and draw beam afterbody weld is bigger, stress value near in addition surpass the requirement of TB/T1335 " standard is identified in railway vehicle Intensity Design and test " strength assessment, in calculation of strength and test, checking is arranged all; If press the AAR evaluation criteria of North America railway association simultaneously, the no underframe tank car of the existing pillow pulling apparatus structure of present domestic employing, the evaluation criteria of the intensity out of reach AAR of the tank body tank shell of its draw beam afterbody.
Summary of the invention
The objective of the invention is the mode of action, the structure of pillow pulling device is optimized, design a kind of rail road tank car traction and bolster device, make the structure of pillow pulling device more become reasonable with beam structure according to the Lognitudinal Impact of Trains compressive force.
Technical scheme of the present invention: the pillow pulling device of no underframe tank car of the present invention comprises end carriage, draw beam assembling, sleeper beam assembling, has a crossbeam mounting structure to be connected with the draw beam afterbody at the draw beam afterbody.
The pillow pulling device of described no underframe tank car, its crossbeam mounting structure comprise the laterally crooked cantilever diaphragm consistent with the tank car lower shape of its upper surface, and the bottom of cantilever diaphragm is connected with the crossbeam lower cover, and there is the cross member side cap plate at the two ends of cantilever diaphragm.
The sheet material welded structure is adopted in the crossbeam assembling, and manufacturing process is simple.Wherein the shape of each part and size are that result according to finite element analysis determines: crossbeam mounting structure upper surface is the crooked cantilever diaphragm consistent with the tank car lower shape laterally, is used to support tank body; The bottom of cantilever diaphragm is connected with the crossbeam lower cover, is used to transmit the load of cantilever diaphragm; There is the cross member side cap plate at the two ends of cantilever diaphragm, are used to improve the stress concentration of cantilever diaphragm end.
The invention has the advantages that: after adopting this beam structure, make the middle part of tank body increase by two supports, shared the stress of a part of sleeper beam, alleviated the situation that carrying is concentrated, limit the vertical and horizontal distortion of tank body, improved the stress concentration phenomenon of sleeper beam and draw beam afterbody.The pillow pulling mounting structure is simple, convenient manufacturing process, and is economical and practical reliable, and can effectively reduce the stress value at tank shell heavily stressed place, prolongs the vehicle operation life-span, saves the cost that repairs.

The specific embodiment
Below in conjunction with accompanying drawing pillow pulling device of the present invention is described in further detail:
In Fig. 1, Fig. 2: 1-end carriage 2-draw beam assembling 3-sleeper beam assembling 4-crossbeam assembling, the 5th, tank body.
This utility model pillow pulling device mainly is made up of draw beam assembling 2, sleeper beam assembling 3, crossbeam assembling 4 etc.
Fig. 3 is the composition diagram of draw beam assembling: 2.1-striker, 2.2-center filler, 2.3-draw beam lower cover, 2.4-body center plate, 2.5-draw beam web.
The draw beam assembling is formed by two blocks of webs, a lower cover assembly welding, and striker, integral type center filler and body center plate adopt C level steel casting.Striker 2.1, center filler 2.2, draw beam lower cover 2.3, body center plate 2.4, draw beam web 2.5 are placed on the assembly welding platform position, location, and the location clamps simultaneously, is welded into draw beam assembling as shown in Figure 3 then.
Fig. 4 is the composition diagram of sleeper beam assembling: 3.1-sleeper beam side pipe, 3.2-lower cover, 3.3-web, 3.4-gusset.
The sleeper beam assembling is that sleeper beam side pipe 3.1, lower cover 3.2, web 3.3, gusset 3.4 are placed on the assembly welding platform position, location, and the location clamps simultaneously, is welded into sleeper beam assembling as shown in Figure 4 then.
Fig. 5 is the composition diagram of crossbeam assembling: 4.1-cross member side cap plate, 4.2-cantilever diaphragm, 4.3-crossbeam lower cover, 4.4-crossbeam gusset.
Cross member side cap plate 4.1, cantilever diaphragm 4.2, crossbeam lower cover 4.3, crossbeam gusset 4.4 are placed on the assembly welding platform position, location, and the location clamps simultaneously, is welded into crossbeam assembling as shown in Figure 4 then.Crossbeam assembles by meridosternous, side cover plate and lower cover and is connected the gusset assembly welding and forms, and the crossbeam assembling is positioned at the draw beam afterbody.
Form on the platform position at the pillow pulling device, draw beam is assembled, after sleeper beam assembling, crossbeam assembling position, is welded into single-piece pillow pulling structure after positioning clamping, at last pillow pulling device and tank body connecting panel are welded, form integral body with tank body.
The longitudinal impact compressive force is as follows in the mode of action of pillow pulling device of the present invention: the vertical compressive force that acts on center filler, except that a part by the web of sleeper beam assembling and side pipe transfer function to tank body, most of draw beam web that assembles along draw beam is to the tank body transmission, when the power along the transmission of draw beam web passes to the crossbeam assembling, this moment, the longitudinal force that a part of draw beam transmits was born in the crossbeam assembling, thereby reduce the draw beam continuation to the longitudinal force that tank body transmits later, the stress value of draw beam afterbody tank shell is reduced.
