Abstract
The invention relates to a center pin self-locking device for a rail wagon. The center pin self-locking device is characterized by comprising a center pin, an upper lock pin, a lower lock pin, limiting rings, a pin ring and a lifting seat; the vertical central lines of two ends of the center pin are provided with two pin holes, the upper pin hole is a circular hole or an oblong hole, and the lower pin hole is an oblong hole; the upper lock pin passes through the upper pin hole, and two ends of the upper lock pin are provided with the limiting rings; the center pin passes through an upper center plate hole and a swing bolster center plate hole; a lower web plate of the swing bolster center plate surface is provided with a pin hole; and the lower lock pin passes through the lower pin hole and the swing bolster web plate pin hole, one end of the lower lock pin is provided with the pin ring, and one side of the swing bolster web plate close to the pin ring is provided with the lifting seat. Because the structure is adopted, the device can effectively prevent and solve the problem of separation or release of an upper center plate and a bogie center plate of the wagon body.
Description
Technical field
The present invention relates to a kind of self-locking device, particularly a kind of railway truck center pin self-locking device.
Background technology
The China railways lorry generally adopts the car body body center plate and the bogie truck truck center plate connection structure of band center pin, and this structure has transmitted load, prevent that the car body body center plate from deviating from the operating needs of bogie truck truck center plate.
The center pin that the China railways lorry is extensively adorned usefulness at present is a kind of straight pin structure, there is chamfering at two ends, body of rod forging molding, processing is simple, easy for installation, center pin one end inserts bolster cartridge hole, and the other end inserts in the car body body center plate hole, the center pin installation site is not retrained by miscellaneous part up and down, can jump up and down.This center pin is simple in structure, prevents that the function that the upper and lower cartridge of vehicle is deviate from also is subjected to certain limitation.Under the bigger circuit running environment of wind-force, car body is increased by side force, might cause car body body center plate and truck center plate and deviate from rollover, application along with some railway specialized equipments, railway truck is in overturning operation, car load handling, when normal operation such as shunting, the car body body center plate also may separate, deviate from the bogie truck truck center plate, causes cartridge abrasion dish to damage unusually, even causes safety misadventure.
Summary of the invention
Technical matters to be solved by this invention provides a kind of railway truck center pin self-locking device safe in utilization.
For solving the problems of the technologies described above, the present invention includes center pin, last lock pin, following lock pin, spacing ring, lock ring, flap seat; Described center pin two ends vertical center line has two pin-and-holes, and the top pin-and-hole is circular hole or slotted hole, and the bottom pin-and-hole is a slotted hole; The described lock pin of going up passes the top pin-and-hole, and last lock pin two ends are provided with spacing ring; Described center pin passes car body body center plate hole and bolster cartridge hole; Described bolster cartridge basifacial web is provided with pin-and-hole; Described lock pin down passes bottom pin-and-hole and bolster web pin-and-hole, and following lock pin one end is provided with lock ring, and the bolster web is equipped with flap seat near lock ring one side.
Preferably, described top pin-and-hole is parallel or angled mutually with the bottom pin-and-hole.
In the such scheme, described flap seat is connected by pin with lock ring.
The present invention has been owing to adopted said structure, can effectively prevent and solves the problem that car body body center plate and bogie truck cartridge separate or deviate from.
Description of drawings
Below in conjunction with the drawings and specific embodiments technical scheme of the present invention is further described in detail.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a scheme of installation of the present invention;
Fig. 3 is the structural representation of center pin.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, center pin 2 is packed in bolster center filler 7 and car body body center plate 8 holes, packs into from the side and goes up lock pin 1, rotates to an angle, and last lock pin 1 two ends can not be deviate under spacing ring 6 backstop actions.The car body that installs center pin 2 and last lock pin 1 is fallen to being contained in to be equipped with on the bolster 10 of cartridge abrasion dish 9, center pin 2 lower ends are encased in inside, bolster 10 cartridge hole, this moment, the center pin lower end did not contact the bolster inner structure, centre of gration pin 2 makes center pin 2 bottom pin-and-holes align with bolster web pin-and-hole, lock pin 3 under packing into, following lock pin 3 one ends are assembled with lock ring 4 with easy disassembly and fixing, bolster web pin-and-hole one side is equipped with flap seat 5, does not deviate from bolster when flap seat 5 is guaranteed lock pin utilization down with lock ring 4 by pin.
Lockpin hole is a circular hole on the center pin 2, also can be slotted hole, cooperates by installing with last lock pin 1, and the center pin upper end is fixed on the car body; The bottom lockpin hole is a slotted hole, guarantees also can not make down lock pin be subjected to the above car body shearing load of cartridge after the maximum abrasion in car body body center plate 8, cartridge abrasion dish 9 and bolster 10 cartridge places.
It should be noted last that, the above specific embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
