Problems solved by technology

[0005] However, the structure of the single-layer skeleton layer of the aramid conveyor belt cannot be glued by the traditional multi-layer fabric core conveyor belt lap joint method, and it is also difficult to realize the steel wire rope ladder method. Most of the aramid conveyor belt joints at home and abroad currently use For finger joints, the joint strength depends entirely on the strength of the rubber body and the shear strength of the bonding interface, the joint strength retention rate is low, and the safety factor of the joint under dynamic conditions is relatively low

Embodiment 1

[0035] Such as Figure 1-4 As shown, an X-ray detection aramid conveyor belt finger joint includes an upper cover rubber 1, an upper reinforcement cloth 2, a first adhesive 3, an aramid core 4, a second adhesive 5, a lower reinforcement cloth 6 and The lower cover glue 7, the above materials are arranged sequentially from top to bottom; the aramid tape core 4 is spliced ​​by the first finger joint 41 and the second finger joint 42; the first glue 3 is provided with several A metal block 8 and a metal rope 9.

[0036] The metal blocks 8 are distributed at adjacent finger positions of the corresponding first finger joints 41 and second finger joints 42 . The metal rope 9 is located at the joining joint of the first finger joint 41 and the second finger joint 42, and the direction is perpendicular to the extending direction of the conveyor belt.

[0037] The length and width of the metal block 8 are both 1.85-2.15mm, and the thickness is 0.99-1.29mm; the diameter of the metal r...

Embodiment 2

[0038] Example 2 X-ray detection method for finger joint displacement of aramid conveyor belt, the specific steps are as follows:

[0039] (1) Finger cutting of aramid conveyor belt: cut the joint area at both ends of the single-layer aramid conveyor belt (such as Figure 1-2As shown), according to the specified joint finger length and finger width, use a special cutting knife to cut the finger shape. When cutting, follow the principle of removing more and leaving less, and remove the excess to keep the cloth surface clean and flat. Facilitate the expansion of the splicing process;

[0040] (2) Spread joint rubber material: according to the conveyor belt joint process, on the heating plate under the joint vulcanizer, cut the corresponding size according to the length of the aramid conveyor belt joint and the thickness of the film, lay the lower rubber material flatly, and then place the previously cut sheet Layers of aramid fingers, aligned to the centerlines of the splice en...

Abstract

The invention relates to a method for detecting the movement of a novel aramid conveyor belt finger-type connector by X rays and belongs to the technical field of aramid conveyor belts. The detectionmethod comprises two parts including an aramid conveyor belt connector region metal configuration structure and an X-ray part; a lead block and a fine steel wire rope are embedded into an aramid conveyor belt finger-type connector part; in a running process of the conveyor belt, when a conveying type separated X-ray metal detector detects that the aramid conveyor belt is subjected to a tension force, relative displacement movement or damages are generated between an inner finger type of the connector and a relative point of the connector. According to the method provided by the invention, equipment is remotely operated and an operator can carry out operation of switching on and off a power supply, switching on and off rays, acquiring an image, monitoring an equipment state and the like ata place far away from an equipment mounting position; all work of equipment operation and state monitoring can be finished when the operator is not on the scene, so that a running position and a running state of the aramid conveyor belt connector are displayed on a computer screen in real time; if abnormal and connector movement conditions occur, the conditions are identified and a user can conveniently and pertinently repair.

Description

technical field [0001] The invention relates to a method for X-ray detection of finger joint twitching of a novel aramid conveyor belt, belonging to the technical field of aramid conveyor belts. Background technique [0002] In recent years, with the accelerated development of the entire global economy, the continuous expansion of the scale of steel, coal, cement, and ports, and the continuous increase in production capacity demand, the transportation of materials in these industries has brought great opportunities and challenges to the conveyor belt industry. Customers have continuously increased requirements for conveyor belt quality, high-strength conveyor belts and energy consumption. At present, the fabric core conveyor belt adopts multi-layer (nylon, polyester) canvas to ensure the strength of the conveyor belt, but the number of layers of fabric core conveyor belt The more the belt body passes through the small-diameter roller, the worse the dynamic flexural performan...
