Abstract
The utility model relates to a doorframe structure for a railway vehicle door, consisting of upright posts which are arranged on two sides, an upper beam, and a lower beam. An L-shaped metal block is respectively arranged on four door corners where the upright posts are connected with the beams. The upright posts and the beams are fixed on the metal blocks. The metal blocks are formed by cold press casting blank materials and plate materials. As a metal block integral structure is respectively adopted at the door corners, the whole doorframe has no welding seam at the door corners, that is, the welding seam is far away from positions with concentrated stress. Furthermore, since the metal block is integrally molded, the strength and the stiffness of the metal block are largely improved, compared with those of the prior thin wall part, thereby improving the load-carrying performance of the whole vehicle body and improving the service life of the vehicle.
Description
Technical field
The utility model relates to a kind of later-model doorframe structure, and particularly a kind of doorframe structure that is installed on the rolling stock car door belongs to machinery manufacturing technology field.
Background technology
As shown in Figure 1, the doorframe of rolling stock is made up of column that is positioned at both sides and lower and upper cross-member at present, and column and crossbeam all are the structures of thin-wall section, is light welding structure at the place, four door angles of column and crossbeam welding.Owing to have weld seam at Men Jiaochu, welding procedure is heated this position, no matter the intensity that makes mother metal how, all cause the load-carrying capacity of commissure to descend, and often there is serious stress concentration in the car body of rolling stock at this position, so cause this position to produce endurance crack, make the weakness of whole locomotive body, and reduce service life owing to this position.
Summary of the invention
The utility model main purpose is to address the above problem and is not enough, and a kind of doorframe structure of later-model rolling stock car door is provided, and it can increase substantially the strength and stiffness of doorframe, thereby improves the load-carrying capacity of car body, increases the vehicle operation life-span.
For achieving the above object, the technical solution of the utility model is:
A kind of doorframe structure of rolling stock car door, by the column that is positioned at both sides, and the lower and upper cross-member composition, being provided with " L " shaped metal piece at the place, four door angles that described column is connected with crossbeam, described column and crossbeam all are fixed on the described derby.
Described derby is an integral structure, described derby be as cast stock or sheet material by cold-formed, be welding between described derby and described column and the crossbeam.
Content to sum up, the doorframe structure of rolling stock car door provided by the utility model, adopted the derby integral structure at Men Jiaochu, make whole doorframe not have weld seam in the door angular position, be about to the position of weld seam away from stress concentration, and because derby is a global formation, than intensity and all raisings greatly of rigidity of traditional thin-wall part, thereby improve car body single-piece load-carrying properties, increase the vehicle operation life-span.
Description of drawings
Fig. 1 prior art structural representation;
Fig. 2 the utility model structural representation.
As depicted in figs. 1 and 2, column 1, crossbeam 2, door angle 3, derby 4.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As shown in Figure 2, a kind of doorframe structure of rolling stock car door, by the column 1 that is positioned at the doorframe both sides, and lower and upper cross-member 2 is formed, be provided with " L " shaped metal piece 4 at 3 places, four door angles that column 1 is connected with crossbeam 2, derby 4 is an integral structure, and it is passed through cold-formed by as cast stock or sheet material, than intensity and all raisings greatly of rigidity of traditional thin-wall part.
As mentioned above, given in conjunction with the accompanying drawings and embodiments scheme content can derive the similar techniques scheme.In every case be the content that does not break away from technical solutions of the utility model, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of technical solutions of the utility model according to technical spirit of the present utility model.
Claims (4)
1, a kind of doorframe structure of rolling stock car door, by the column that is positioned at both sides (1), and lower and upper cross-member (2) is formed, it is characterized in that: locate to be provided with " L " shaped metal piece (4) at four door angles (3) that described column (1) is connected with crossbeam (2), described column (1) all is fixed on the described derby (4) with crossbeam (2).
2, the doorframe structure of rolling stock car door according to claim 1 is characterized in that: described derby (4) is an integral structure.
3, the doorframe structure of rolling stock car door according to claim 2 is characterized in that: described derby (4) adopts the stock or the sheet material of cool working casting.
