Train collision self-turning safety table

Abstract

A train collision self-turning safety table comprises a table top, guiding sliding blocks, supporting rib plates, a mechanism installation base, a torsional spring, table top locking and positioning keys and a buffer spring. The mechanism installation base is installed on a wall beside a train seat. The two supporting rib plates are installed on the mechanism installation base in parallel. The table top is installed on the two supporting rib plates. The guiding sliding blocks, the torsional spring and the buffer spring are installed below the table top and fix the table top. The seven table top locking and positioning keys are uniformly and fixedly installed on a panel of the mechanism installation base in an arc shape. The train collision self-turning safety table can buffer the collision between a passenger and the table top when a train accident happens, and therefore the response time for the passenger to conduct self-protection actively is prolonged. Through turning of the self-turning table, the contact form between the passenger and the table is changed from line contact to surface contact, and the contact area between the passenger and the table is greatly increased; and according to the Newton's laws, the pressure borne by the passenger can be effectively decreased, and the passive safety of the passenger is improved.

Description

Technical field [0001] The invention relates to a train collision self-turning safety table, belonging to the technical field of train passive safety machinery. Background technique [0002] China has a vast territory, and railways undertake the heavy tasks of passenger transportation and bulk cargo transportation. At present, when most mid- to long-distance passengers travel, considering safety, price, and comfort, they are still the first choice for railways. This also provides improvements for railway transportation safety. High demands. For example, at 20:50 on July 23, 2011, the D301 train from Beijing South to Fuzhou and the D3115 train from Hangzhou to Fuzhou South had a rear-end collision in Wenzhou, Zhejiang. The first to fourth positions of D301 train were off the line, and the 15th and 16th positions of D3115 train were off the line. The accident caused more than 200 casualties. It can be seen that the consequences of a train collision are very serious. Therefore, i...

Problems solved by technology

[0003] Relevant experts and scholars have studied this kind of train collision accidents and found that after a train collision, a major cause of passenger injury or even death is that the seats on the train are not similar to the seat belts and airbags installed on ordinary family cars. Advanced safety equipment to improve the passive safety of passengers, so when the train collides, the passengers facing the forward direction of the train can only keep moving forward at the speed before the collision under the action of inertial force until they encounter obstacles and collide After stopping, the damage is caused by the
