Cutting type anti-creeper

Abstract

The invention discloses a cutting type anti-creeper. The cutting type anti-creeper comprises an anti-creeping toothed plate, energy absorption tubes, a tool installing flange and cutting tools, wherein one ends of the energy absorption tubes are fixedly arranged on the anti-creeping toothed plate, and the tool installing flange is arranged on the other ends of the energy absorption tubes in a sleeved mode, the cutting tools are fixedly arranged on the tool installing flange, make contact with the energy absorption tubes and are used for cutting the energy absorption tubes when the impact force reaches a set threshold value. According to the cutting type anti-creeper, optimization is conducted on a cutting type buffer structure, by means of the mode that a process groove is machined on a buffer structural part, a friction force change caused by deformation of the energy absorption tubes is reduced, and stable energy absorption process of the cutting type anti-creeper can be facilitated. Meanwhile, the bearing capacity of the cutting type anti-creeper is improved, the friction force of the buffer structure is reduced, and therefore the stability and precision of the buffer powder are improved.

Description

technical field [0001] The invention relates to the technical field of buffering and energy-absorbing devices, in particular to a cutting type anti-climbing device. Background technique [0002] Cushioning, as an important topic in the field of safety protection, has been widely concerned. The development of this field has derived a wide variety of structural forms such as hydraulic pressure, springs, and honeycombs. A buffer structure based on the principle of metal cutting has also been widely used. rail transit industry. The buffer absorbs the huge energy brought by the impact by using the principle of converting kinetic energy into metal deformation and heat energy during the metal cutting process. This structure is simple and efficient, and can operate stably under various harsh working conditions. [0003] With the rapid development of China's high-speed rail and urban rail, convenient and efficient rail transit has become the first choice for many people to travel, a...
