Abstract
The invention provides a mistaken-coupling-preventive non-rotary coupler of a railway truck, and a railway truck. The non-rotary coupler comprises a mounting portion and a coupling portion, one side of the coupling portion is a coupler wrist side while the other side of the same is a coupler tongue side, the coupling portion is connected with a mistaken-coupling-preventive supporting arm which is positioned on the coupler tongue side of the coupling portion, the overhanging direction of the mistaken-coupling-preventive supporting arm is away from the mounting portion, and an overhanging end portion of the mistaken-coupling-preventive supporting arm has a mistaken-coupling-preventive action face. In the above scheme, the non-rotary coupler is provided with the mistaken-coupling-preventive supporting arm, so that mutual hooking of two non-rotary couplers can be prevented to stop coupling of two railway trucks, and the problems that the non-rotary couplers are damaged and unloading efficiency is lowered caused by the fact that the two non-rotary couplers are mutually hooked when turning for unloading without demounting a tippler on a railway vehicle are solved.
Description
Technical field
The present invention relates to the hitch technology of railway truck, relate in particular to and anti-error company of a kind of railway truck hang fixedly hitch and railway truck.
Background technology
Rolling stock is organized into groups to connect by hitch and is hung, thereby guarantees the connection between adjacent two rolling stocks.Organize into groups at rolling stock and to connect when hanging, following several form is arranged: first kind is that the two ends of rolling stock all install and fix hitch, two adjacent rolling stocks by two fixedly hitch connect and hang over together; Second kind is that swivel draw bar is all installed at the two ends of rolling stock, and two adjacent rolling stocks connect by two swivel draw bars and hang over together; The third is that an end of rolling stock installs and fixes hitch, the other end is installed swivel draw bar, and two adjacent rolling stocks connect with fixing hitch by swivel draw bar and hang over.
Along with greatly developing of rolling stock transport capacity, the requirement of unloading is also further improved, adopt rolling stock not pluck to separate hitch directly to improve rate of discharging with the overturn mode of unloading of tipper.Adopt the overturn mode of unloading of tipper, then the mode of hanging of railway truck all is to adopt swivel draw bar and fixing hitch to connect the mode of hanging, and namely each rolling stock all is that an end is fixing hitch, and the other end is swivel draw bar.When rolling stock overturned unloading, an end swivel draw bar rotated voluntarily, and the other end fixedly hitch swivel draw bar that then drives another car rotates together, realized that vehicle is not plucked to separate the hitch upset and unload.When rolling stock decomposes the back or organizes into groups again, vehicle need be connected extension again, at this moment, the principle of hanging also be guarantee swivel draw bar and fixedly hitch connect extension, but might there be error in practical operation, make two fixedly hitch connect and to hang over together, do not pluck when separating that tipper overturns unloading on the hitch at rolling stock like this, can cause hitch to damage and reduce the problem of rate of discharging.
Summary of the invention
The invention provides and anti-error company of a kind of railway truck hang fixedly hitch and railway truck, in order to solve the deficiencies in the prior art.
