Steel wire rope core conveying belt for TBM and preparation method thereof

Abstract

The invention discloses a steel wire rope core conveying belt for a TBM and a preparation method of the steel wire rope core conveying belt. The steel wire rope core conveying belt comprises an uppercovering rubber layer, a lower covering rubber layer, a middle core rubber layer, side rubber layers and multiple left and right twist direction steel wire ropes. The left and right twist direction steel wire ropes are arranged and distributed in the middle core rubber layer at intervals, the middle core rubber layer is respectively covered with the upper covering rubber layer and the lower covering rubber layer from top to bottom and respectively covered with the side rubber layers from left to right, the diameter of the left the right twist direction steel wire ropes of the middle part is 4-5 mm, the distance is 8-10 mm, the diameter of the left twist direction steel wire rope and the right twist direction steel wire rope of the two side parts is 4-5 mm, the distance is 12-15 mm, the left and right twist direction steel wire ropes of the middle part account for 60-70% of the width of the conveying belt, and the left and right twist direction steel wire ropes of the two side parts account for 30-40% of the width of the conveying belt. The conveying belt is high in strength, the diameter of a steel wire rope used under the same strength is small, the overall flexibility is high, the elongation is low, the flame-retardant safety performance is high, the conveying resistance is small, deviation is not likely to happen and the steel wire ropes on the two sides have good grooving performance.

Description

technical field [0001] The invention relates to a steel cord conveyor belt for TBM and a preparation method thereof. Background technique [0002] TBM is the abbreviation of Tunnel Boring Machine. The existing steel cord conveyor belt for TBM has the following disadvantages: 1. The diameter of the steel cord used is large, the breaking force is low, and the overall flexibility of the conveyor belt is poor; 2. The resistance of the steel cord conveyor belt is large, and the conveying The power of the tunnel boring machine increases accordingly, and the power consumption increases; 3, the steel wire rope has a single structure and is evenly arranged. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems existing in the prior art, and to provide a steel cord conveyor belt for TBM and a preparation method thereof. Strong flexibility, low elongation, high flame retardant safety performance, small conveying resistance, ...
