Embodiment Construction

[0014] Referring to Fig. 1-Fig. 6, the present invention connects the seat plate 1.1 with bolts or rivets through the installation hole 6.1 below the end of the railway freight car draw beam 6. An upper baffle 1.3 and a lower baffle 1.4 parallel to each other are assembled and welded on the seat plate 1.1, a front baffle 1.2 perpendicular to the upper and lower baffles is welded in front of the upper and lower baffles, the upper baffle 1.3, the lower Baffle plate 1.4 and front baffle plate 1.2 constitute safety chain seat 1. A support hole 1.21 is opened on the front baffle plate 1.2, and a buffer rod body 2.1 is passed through the support hole 1.21 to be located in the safety chain seat 1, and the buffer rod body 2.1 in the safety chain seat 1 is set with a buffer spring 3, a movable stop Block 4 and nut, locking back nut, cotter pin, movable block 4 are vertically positioned between upper baffle plate 1.3 and lower baffle plate 1.4. The supporting hole 1.21 is a rectangular...

Abstract

The present invention relates to a tractive connection mechanism of a lorry, in particular to a safety protection device for a draw gear of a freight train. A seat board is fixed under the end of a tractive beam of the lorry and an upper baffle and a lower baffle are welded on the seat board. A front baffle constituting a safety chain seat is welded before the upper baffle and the lower baffle. The front baffle is opened with a support hole, through which a buffer rod drills. The noumenon of the buffer rod is located in the safety chain seat and a buffer spring and an active stop dog are sleeved on the noumenon of the buffer rod. The other end of the buffer rod noumenon is a buffer rod head and the end of the buffer rod head is opened with a connecting hole. The buffer rod head is connected with a connecting link via a connecting hole. The link is connected with the head of the draw gear. The advantage is that the present invention can provide the emergency protective measures for the draw gear of the tractive train and ensure the safety of the train furthest.

Description

technical field [0001] The invention relates to a traction and coupling mechanism for railway freight cars, in particular to a safety protection device for the couplers of railway freight cars. Background technique [0002] As we all know, due to the great differences in railway road conditions, railway vehicle maintenance systems, and social security conditions in various countries in the world, the application conditions of railway freight cars are very different. In some countries, due to poor railway road conditions, unsound railway vehicle maintenance system, and social security chaos, the technical condition of vehicles is poor, parts are lost, severely damaged, and the failure rate of key components is high, seriously endangering traffic safety. Therefore, it is necessary to take necessary security measures for some key components that may endanger the safety of the train to ensure the safety of the train. Contents of the invention [0003] The problem to be solved...
