Abstract

The invention discloses an oscillating type buffering device for a car pressing mechanism of a car dumper. The oscillating type buffering device for the car pressing mechanism of the car dumper comprises a stop lever, a counterweight and a buffer, wherein the buffer comprises an oscillating rod, a spring I, a spring II, an upper baffling plate, a middle baffling plate and a lower baffling plate, the oscillating rod comprises a head part and a rod part, the rod part is fixedly connected with the lower baffling plate after penetrating through the middle baffling plate, the spring I is arranged between the upper baffling plate and the middle baffling plate, the spring II is arranged between the middle baffling plate and the lower baffling plate, the middle baffling plate is hinged at the lower part of the stop lever through a hinging point II, and the head part is hinged at the counterweight through a hinging point III. According to the oscillating type buffering device for the car pressing mechanism of the car dumper, based on the principle that the two ends of a rotatable rod piece are hinged and are only under tension and compression, the problem of bending damage to a loop bar due to transverse force is solved by the rotation of the rod piece, and meanwhile the problems of buffering and compression are solved by the oscillating rod and the rotatable hollow middle baffling plate; the oscillating type buffering device has the advantages that the structure is compact and reliable, and the stress is simple and reasonable.

Description

technical field

[0001] The invention relates to a buffer device for a car dumper pressing mechanism, in particular to a swing-type buffer device for a counterweight type mechanical car pressing device of a car dumper. Background technique

[0002] The dumper unloading system is an efficient automatic operation system widely used in steel mills, power plants, ports, etc. It is used to dump railway gondolas. Existing dumpers in foreign countries use a fully mechanical counterweight type pressing device, in which the counterweight device is hinged, and a buffer device is provided at one end of the counterweight to reduce the impact of the counterweight when the tipping speed changes. Similar foreign equipment has a large space in the buffer, so methods such as long-stroke rubber buffer are generally used to solve the displacement problem between the relative swinging counterweight and the relative stationary stop rod.
