Railroad transport crawler belt equipment non-overrun device cloth layer rubber bearing body

Abstract

A railroad transport crawler belt equipment non-overrun device cloth layer rubber bearing body comprises a rectangular pad, the pad includes a power layer (1), the power layer (1) is arranged along the horizontal direction, the power layer (1) comprises 3-5 layers of EP canvas layers (2) which are arranged along the horizontal direction, the mutual adjacent surfaces of the 3-5 layers of EP canvas layers (2) are connected and bonded by 401 adhesive, the upper surface of the power layer (1) is bonded with an upper adhesive layer (3) by the 401 adhesive, the lower surface of the power layer (1) is bonded with a lower adhesive layer (4) by the 401 adhesive, the thickness of the power layer (1) is 60-80mm, the thickness of the upper adhesive layer (3) is 30-50mm, and the thickness of the lower adhesive layer (4) is 20-40mm. The purpose is to provide the railroad transport crawler belt equipment non-overrun device cloth layer rubber bearing body which has high strength and high tear resistance and large surface friction coefficient in the environment with a temperature of-40 DEG C to 60 DEG C, and can be well adapted to chilly condition and high temperature condition.

Description

technical field [0001] The invention relates to a cloth-layer rubber pressure-bearing body for a non-overrunning device for railway transport crawler equipment. Background technique [0002] Our country's tanks have continued the design concept of the Soviet Union from the early days to the present. The width of the tank itself is wider than that of railway trucks. When encountering platforms, bridges, and tunnels during railway transportation, the railway trucks transporting tanks may not be able to pass, and they need to pass without exceeding the limit. The device solves the ultra-wide problem in the process of tank transportation. At the same time, due to the increasing frequency of military exercises and training in my country in recent years, the frequency of transporting tank military equipment by railway continues to increase. In line with the requirements of actual combat, it is best not to adjust the load during transportation. The tank is reinforced and anti-slip, w...

Problems solved by technology

However, the existing pressure-bearing bodies made of rubber materials are difficult to meet the requirements in terms of strength, tear resistance, friction coefficient, adaptability to high cold and high heat conditions, especially in terms of friction coefficient, tear resistance and cold resistance. It is quite different from the requirements of users, so it needs to be developed and improved
