Description
Technical Field
The utility model relates to a railway transportation equipment technical field, concretely relates to strenghthened type coupling for rail vehicle.
Background
The F-type interlocking coupler is designed on the basis of an H-type tight-lock coupler of a passenger car, has high structural strength, small coupling clearance, functions of anti-drop, interlocking and automatic centering, reliable tri-state action and anti-jump performance and good curve trafficability. The F-type coupler has risen to the AAR standard coupler in 1954. In order to adapt to the transportation of bulk goods such as coal and the like and meet the requirement of unhooking, overturning and unloading, a rotatable FR type interlocking coupler is developed on the basis of an F type coupler and is matched with the F type coupler, so that the F type interlocking coupler is widely applied to trucks transported by heavy-load units, and the transportation efficiency is greatly improved. The model of the AAR active service F-type coupler is mainly F-type, and the coupler also comprises F79DE with an anti-drop SF type and a long coupler body.
The use condition of the existing F-shaped coupler is investigated in detail, and the investigation result shows that the F-shaped coupler has some defects in structural strength, and in the actual use process, part of countries and regions can be overloaded. In actual use, the weakest part in the whole coupler body of the car coupler, namely the upper traction table, the lower traction table and the peripheral structures of the upper traction table and the lower traction table are found, so that the defects of cracks, breakage and the like are particularly easy to occur, and potential safety hazards exist.
Disclosure of Invention
To the above problem, the utility model provides a strenghthened type coupling for rail vehicle.
The utility model adopts the technical proposal that: a reinforced coupler for a railway car, comprising: the coupler comprises a coupler body, a coupler tail arranged at one end of the coupler body and a coupler head arranged at the other end of the coupler body;
the coupler head includes: the device comprises a traction table and an interlocking device which is matched and connected with the traction table;
the traction table comprises: an upper traction table and a lower traction table; and a reinforcing rib is arranged at the back of the interlocking sleeve opening of the interlocking device.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Referring to fig. 1 to 1, as shown in fig. 1 to 1, a reinforced coupler for railway vehicles includes: the car coupler comprises a car coupler body 1, a car coupler tail 2 arranged at one end of the car coupler body 1 and a car coupler head 3 arranged at the other end of the car coupler body 1;
the coupler head 3 includes: the device comprises a traction table and an interlocking device which is matched and connected with the traction table;
the traction table comprises: an upper traction table 4 and a lower traction table 5; and reinforcing ribs are arranged on the back of the interlocking looping 6 of the interlocking device.
It should be noted that, in the weakest place in the coupler body, that is, the upper and lower traction table parts bearing the coupler knuckle traction force, conditions such as cracks and fractures are particularly easy to occur, thereby causing potential safety hazards. The main invention point of the scheme is that the structural strength of the traction table is greatly improved by changing the wall thickness of the traction table and the wall thickness of the tail wall of the car coupler, so that the traction capacity is improved, and the traction table is more reasonable in stress.
Under the condition that the top surface of the lower traction table is not changed, the root surface of the lower traction table is lifted upwards by 5mm, so that the wall thickness is thickened to 22.5mm from the original 17.5mm, and under the condition that the top surface of the upper traction table is not changed, the root surface of the upper traction table is lifted downwards by 5mm, so that the wall thickness is thickened to 24.5mm from the original 19.5 mm; the structure strength of the traction table is greatly improved on the whole, the traction capacity of the traction table is greatly improved, the bending moment born by the upper traction table and the lower traction table in the traction process is reduced, and the traction capacity of the upper traction table and the lower traction table is enhanced.
In addition, the wall thickness of the F-shaped hook tail is reinforced, and the wall thickness of the transverse part of the hook tail is increased from 14.3mm to 17.3mm, so that the strength of the hook tail is increased, and the hook tail can bear larger tensile load; meanwhile, the structure of the F-shaped coupler is optimized, the reinforcing rib at the back of the interlocking sleeve opening is optimized from one of the original central positions to an upper reinforcing rib and a lower reinforcing rib, so that the reinforcing rib is stressed more reasonably under the condition of unchanged functions, the reinforcing rib at the back of the coupler lock sleeve is shortened, and the purpose of reducing weight is achieved.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
