Problems solved by technology

No matter what kind of joint method is used for lap vulcanization, the steel wire rope needs to be cut off, which directly destroys the breaking force of the steel wire rope. Since there is no friction between each other after the lap joint, once there is a problem in any link of the vulcanization process, environment, and materials, it will be impossible. It is very easy to break the drawing rope, which will affect the quality of the joint

Embodiment Construction

[0016] Step 1: First, fix the two joints of the steel cord tape firmly to prevent movement, and remove the glue at the joints to expose a certain length of the steel cord. The six steel cords on the left are respectively counted as 1a, 2a, 3a, and 4a , 5a, 6a; the six wire ropes on the right are respectively counted as 1b, 2b, 3b, 4b, 5b, 6b;

[0017] The second step: keep 1a, 3a, 5a and 2b, 4b, 6b according to the length of a=0.9m; keep 2a, 4a, 6a and 1b, 3b, 5b according to the length of b=1.5m;

[0018] The third step: Divide 1a, 3a, 5a and 2b, 4b, 6b steel wire rope cores into 3 strands for strand breaking, divide 2a, 4a, 6a and 1b, 3b, 5b steel wire rope cores into 4 strands for strand breaking; or divide 1a, 3a, 5a and 2b, 4b, 6b steel wire rope cores are divided into 4 strands for strand breaking, 2a, 4a, 6a and 1b, 3b, 5b steel wire rope cores are divided into 3 strands for strand breaking, and the strand length c=800mm;

[0019] Step 4: After the strands of the steel...

Abstract

The invention discloses a steel cable belt joint connection method. The method comprises the following steps: firstly breaking strands of a steel cable of a steel cable belt joint, then interleaving and weaving, and then vulcanizing. A knitted steel cable is connected not only by virtue of adhesion of size, steel rope knitting friction force is also improved, tensile strength of a joint after vulcanization is also improved, secondary protection is added for a belt joint, and safety of the joint can be guaranteed more powerfully. Even if problems appear in vulcanization technology, environment and material links and even after the joint is aged and the steel cable is degummed, the steel rope can be pulled tighter, and laddering, rope breaking, or a belt breakage accident can not be caused.

Description

technical field [0001] The invention relates to a splicing method of flame-retardant steel cord tape for mine use. Background technique [0002] Steel cord strong belt conveyors are generally installed on the throat of mine coal transportation. Once a failure occurs, it will seriously affect the normal production of the entire mine. The most serious accident of steel cord belt is broken belt accident. Practice has proved that the joint of the steel cord tape is the weakest place in the tape, and the broken belt mainly occurs at the joint. The occurrence rate of broken belts at joints reaches 75%-80%. [0003] At present, there are three types of joints for steel cord tape joints: first-level joints, second-level joints, and third-level joints. The levels are distinguished according to the number of segments of the long and short heads. Among them, the former two are suitable for tapes with a small number of wire ropes, small diameters, and large gaps, and the latter is sui...
