Manual coupling buffer structure

Abstract

The invention provides a manual coupling buffer structure. The manual coupling buffer structure comprises buffers (3), two clamp rings (21) and two traction rods (40). Notch grooves are formed in the clamp rings (21), and connecting necks (42) are formed in one ends of the traction rods (40); and the clamp rings (21) are mutually connected with the connecting necks (42) on the inter-adjacent traction rods (40) in a clamped mode through flange parts located on the two sides of the notch grooves, every two clamp rings (21) are connected in series through connecting bolts (6) and fixedly connected with the traction rods (40) to form a whole body, and the buffers (3) are connected at the free ends of the traction rods (40). By utilizing the manual coupling buffer structure, the longitudinal impact between vehicles can be alleviated, when the mutual coupling state between the vehicles needs to be removed, an operating worker only needs to disassemble the connecting bolts with the help of a simple auxiliary tool, and then disconnection between every two adjacent vehicles can be achieved; and the manual coupling buffer structure has the outstanding advantages that the structure is simple, operation is convenient, the coupling reliability is high and the implementation cost is low.

Description

technical field [0001] The invention relates to the technical field of vehicle coupling, in particular to a manual coupling buffer structure. Background technique [0002] The domestic passenger sports car technology is relatively mature and has reached the international leading level. However, the freight car group has just started, and many technologies are still being researched and explored, for example, the coupler buffer device and so on. At present, most domestic freight locomotives use 100-type coupler buffer devices, and most EMUs use close-connected coupler buffer devices. These two coupler buffer devices have their own shortcomings for freight train units, mainly because of the longitudinal impact they receive. Larger, complex structure, and higher manufacturing process requirements, not only long production cycle, but also high cost. Especially for the narrow-gauge freight car group, because the volume of this freight car itself is small, its cargo capacity is a...

Problems solved by technology

At present, most domestic freight locomotives use 100-type coupler buffer devices, and most EMUs use close-connected coupler buffer devices. These two coupler buffer devices have their own shortcomings for freight train units, mainly because of the longitudinal impact they receive. Larger, complex structure, and higher manufacturing process requirements, not only long production cycle, but also high cost

Especially for the narrow-gauge freight car group, because the volume of this freight car itself is small, its cargo capacity is also small, therefore, the traction force required during its operation is also relatively small, if still adopt the existing Couplers or chains used for coupling and towing between vehicles lead to higher operating costs
