Abstract
The invention discloses a replaceable connection structure of a main bogie structure and a bogie component. The connection structure is characterized in that two apertures with crossed central lines and vertical directions are formed on a main structure component, wherein a cylindrical pin is inserted in one aperture; a threaded hole is formed on the cylindrical pine; and a connecting bolt is in threaded connection with the cylindrical pin through the other aperture. According to the invention, the bogie component is connected to the main bogie structure by the connecting bolt and the cylindrical pin with the threaded hole, thereby effectively avoiding the abandonment of the main structure caused by the thread damage of the main structure component, greatly prolonging the service life of the main structure component and reducing the periodical cost of the service life of the product.
Description
Technical field
The invention belongs to the high-speed railway passenger technology, relate to the connection structure between truck components and the bogie truck main structure, be applied on the CRH5 type EMU CA250 bogie truck.
Background technology
Traditional truck components is connected directly tapping on the framework main structure, the technology that bolt directly is screwed into of adopting with bogie truck main structure (for example framework, bolster).Adopt this kind technology, main structure screw buckles such as framework are damaged in car inspection and maintenance or unloading process easily, can only in case misoperation will cause scrapping of whole main structure, cause very big waste through repair welding or the reaming method solution of tapping again.
Goal of the invention
Technical matters to be solved by this invention provides a kind of interchangeable connection structure, inserts main structural components, plays the effect in tapping thread hole on the traditional sense, thereby avoids main structure owing to thread failure is scrapped.
For solving the problems of the technologies described above; The present invention provides the replaceable connection structure of a kind of bogie truck main structure and truck components; It is characterized in that: open on main structural components that two line of centerss intersect, the vertical unthreaded hole of direction; Straight pin of grafting in one of them unthreaded hole; On straight pin, have tapped bore, tie bolt is threaded with straight pin through another unthreaded hole.
When making tie bolt fracture fault, connect still effectively, safety catch is set below main structural components, straight pin one end is processed with step, and the other end has pin-and-hole, and straight pin connects the anti-run safety connecting panel through inserting spring cotter in the pin-and-hole.
Tie bolt of the present invention is connected truck components on the bogie truck main structure with the straight pin that has tapped bore; Can avoid because the main structural components thread failure causes scrapping of main structure by actv.; Can improve the service life of main structural components greatly, reduce product life cycle cost.
Description of drawings
Fig. 1 is a main structural components structural representation among the present invention;
Fig. 2 is a straight pin structural representation among the present invention;
Fig. 3 is a structural representation of the present invention.
The specific embodiment
With reference to Fig. 1, open on main structural components 1 that two line of centerss intersect, the vertical unthreaded hole of direction, wherein unthreaded hole 2 diameters of original thread hole site are less, and perpendicular unthreaded hole 3 diameters are bigger, below main structural components, are integral with it and are provided with safety catch 4.
With reference to Fig. 2, open tapped bore 6 on the straight pin, straight pin one end is processed with step 5 simultaneously, and the other end has pin-and-hole 7.
With reference to Fig. 3; In the bigger unthreaded hole of diameter, insert straight pin 12; Drawing pull bar 8 is placed on main structural components 1 safety catch 4 places, and tie bolt 9 is gone in the straight pin through drawing pull bar and the less unthreaded hole fine jade of diameter, accomplishes being connected between drawing pull bar and the main structural components.Safety catch 4 and anti-run safety connecting panel 10 through step on the straight pin and increase main structural components; At bolt because abnormal load or sole mass problem when fractureing fault; Connect still effective; Avoid because thread failure causes scrapping of main structural components; Can improve the service life of main structural components greatly; Reduce product life cycle cost, the safety that has improved this structure greatly.The anti-run safety connecting panel is fixed through spring cotter 11.
Claims (2)
1. the replaceable connection structure of bogie truck main structure and truck components; It is characterized in that: open on main structural components that two line of centerss intersect, the vertical unthreaded hole of direction; Straight pin of grafting in one of them unthreaded hole; On straight pin, have tapped bore, tie bolt is threaded with straight pin through another unthreaded hole.
2. the replaceable connection structure of bogie truck main structure according to claim 1 and truck components; It is characterized in that: safety catch is set below main structural components; Straight pin one end is processed with step; The other end has pin-and-hole, and straight pin connects the anti-run safety connecting panel through inserting spring cotter in the pin-and-hole.
