Problems solved by technology

[0003] In order to solve the defects such as low interface strength, poor safety and reliability, large interface length, short service life, and easy occurrence of sudden belt breaking accidents in the traditional steel cord conveyor belt vulcanized glue joint, the present invention adopts a new steel wire rope arrangement method to improve the conveyor belt. The ratio of the staggered arrangement of the steel wire ropes at both ends increases the insertion and withdrawal resistance of the steel wire ropes in the rubber. High-strength steel wire ropes are used to connect the locks, and the parallel and staggered steel wire ropes are tensioned and locked, so that the originally parallel steel wire ropes are connected together. , provide tension, improve the quality and safety of the joints of the steel cord conveyor belt in essence, realize the connection between the interface and the conveyor belt, and use it for the same service life

Embodiment approach 1

[0023] figure 1 The schematic diagram of the new type of steel wire rope arrangement and combination at the interface of the steel cord conveyor belt and the wire rope connection lock (3) is shown in , in which the new type of wire rope arrangement is suitable for lap joints above the second level, image 3 The old-fashioned two-stage lapping method is shown in the figure. Two steel wire ropes protrude from the second end of the conveyor belt (2), one of which is equal to the length of the joint, and the other is half the length of the joint. 1 / 2 long steel rope (16) of end is relative, inserts a long steel rope from conveyor belt first end, so repeatedly the ratio of its steel rope staggered arrangement is 66%. Figure 4 The old-fashioned three-stage lapping method is shown in the middle. The steel wire ropes are divided into three types: long, medium and short. One-third of the long steel wire rope protruding from end A is opposite, and one-third of the long steel wire rope...

Embodiment approach 2

[0025] exist figure 1 The above shows the use of steel wire ropes to connect the buckles (3) to connect the staggered steel wire ropes in groups of two, so that the two staggered steel wire ropes form a steel wire rope with full tension, and do not rely on the insertion and removal of rubber. The resistance can provide the tension strength guarantee for the interface. Taking the old-fashioned three-stage lapped conveyor belt as an example, the density of the wire ropes at the interface is 33% higher than the original wire rope density of the conveyor belt. Finally, the number of wire ropes that can provide full tension accounts for 67% of the number of wire ropes with the original belt, which can fully meet the needs of operation under normal conditions (usually the safety factor of the conveying system design will not be lower than 140%), so the new type The steel wire rope arrangement method is combined with the steel wire rope connection lock, and the steel wire rope expose...

Abstract

The invention relates to a novel method for configuring and connecting steel ropes. In order to solve the problems of low strength, low safe reliability, and the like of an interface in vulcanized glued connection with a traditional steel rope core conveyor belt, a novel method for configuring the steel ropes is adopted for increasing the ratio of staggered arrangement of the steel ropes at two ends of the conveyor belt and increasing the insert-plug resistance of the steel ropes in rubber, high-strength steel ropes are connected with a lock latch, the steel ropes in parallel staggered arrangement are tensioned and locked, the originally parallel arrayed steel rope main bodies are connected together and a tensioning force is supplied, so that the quality and safety of the connector of the steel rope core conveyor belt are essentially increased, the constant strength connection of the interface and the conveyor belt is realized and the usage with same service life is realized. Adhesive and solidifying rubber are used for gluing a thin rubber sheet, a reinforcing rubber sheet, edge rubber, upper covering rubber and lower covering rubber and wrapping the steel ropes in the area of the interface of the conveyor belt, so as to finish the cold splicing connection of the interface of the steel rope core conveyor belt. The novel method is huge in practical significance.

Description

Technical field [0001] The invention is a new method for on-site vulcanization glue bonding or cold bonding of steel cord conveyor belts, which can improve the strength of the joint, shorten the length of the joint, and improve the safety performance of the joint. Locking the parallel and staggered steel wire ropes can improve the joint quality and safety of the steel cord conveyor belt in essence, and at the same time can shorten the joint length, save equipment, manpower and the cost of joint materials and belts, and improve the overall service life of the conveyor belt . Combined with the cold bonding technology, the cold bonding steel cord conveyor belt interface can be realized, which solves the problem that the steel cord conveyor belt interface relies on hot vulcanization bonding for a long time, and has great practical significance. Background technique [0002] Steel cord conveyor belts are widely used by industrial and mining enterprises such as ports, power plant...
