鋼絲繩輸送帶由于具有較大的承載能力和較高的運(yùn)行速度而被廣泛用于煤礦主軸的運(yùn)輸。近年來,隨著對煤礦生產(chǎn)的重視,對輸送帶的阻燃性能提出了更加嚴(yán)格的要求。但是,由于技術(shù)故障,傳送帶的耐磨性降低了。例如,達(dá)柳塔煤礦主軸的傳送帶在運(yùn)行2年后,與側(cè)輥的接觸區(qū)域嚴(yán)重磨損,電纜暴露在外。如果不修復(fù),它將不會運(yùn)行或損壞。這將極大地影響礦山的生產(chǎn)進(jìn)度。因此,及時(shí)快速修復(fù)鋼絲繩輸送帶的局部磨損對保證煤礦的正常生產(chǎn)具有重要意義。
Wire rope conveyor belt is widely used in coal mine shaft transportation because of its large bearing capacity and high running speed. In recent years, with the national attention to coal mine safety production, the flame retardant performance of conveyor belt has been put forward more stringent requirements. However, due to technical failure, the wear resistance of the conveyor belt is reduced. For example, after two years of operation, the conveyor belt of Daliuta coal mine's main shaft was seriously worn and the cable was exposed. If it is not repaired, it will not run or be damaged. This will greatly affect the production progress of the mine. Therefore, it is of great significance to repair the local wear of steel rope conveyor belt in time to ensure the normal production of coal mine.
1局部磨損修復(fù)方法是修復(fù)鋼絲繩傳送帶局部損壞的更常用方法,有以下三種方法:
1. Local wear repair method is the most commonly used method to repair the local damage of steel wire rope conveyor belt
(1)局部橡膠硫化方法使用小型硫化機(jī)進(jìn)行硫化局部損壞。由于硫化機(jī)的尺寸限制,修復(fù)速度僅為0.5mh。此方法不適用于長距離維修。
(1) The local rubber vulcanization method uses a small vulcanizer to cure the local damage. Due to the size limitation of vulcanizing press, the repairing speed is only 0.5mh. This method is not suitable for long distance maintenance.

(2)橡膠修補(bǔ)法采用德國技術(shù)的橡膠修補(bǔ)法,其的優(yōu)點(diǎn)是修復(fù)速度快。拋光要維修的區(qū)域,清潔后涂上膠水并粘貼橡膠,即可開啟機(jī)器。不利的一面是,在運(yùn)行6090天后,通常會從橡膠上脫落。的問題是,如果傳送帶在潮濕的環(huán)境中運(yùn)行,水蒸氣將積聚在粘合表面的間隙中,并使電纜生銹。隨著時(shí)間的流逝,鋼絲繩將生銹并斷裂,甚導(dǎo)致整個(gè)傳送帶突然斷裂。據(jù)了解,2006年,盤江煤電公司在貴州的霍普礦發(fā)生了鋼絲繩輸送帶斷裂的情況。這是因?yàn)樵诘诙问褂孟鹉z修補(bǔ)方法修復(fù)了局部損壞。表面修復(fù)沒有問題,但糊劑區(qū)域集中。水蒸氣引起的銹蝕使多條鋼纜斷裂,導(dǎo)致傳送帶突然斷裂,從而引發(fā)嚴(yán)重事故。
(2) The rubber repair method adopts the rubber repair method of German technology, which has the greatest advantage of fast repair speed. Polish the area to be repaired, apply glue and glue after cleaning, and then start the machine. The disadvantage is that after 60 to 90 days of operation, it usually falls off the rubber. The biggest problem is that if the conveyor belt is operated in a humid environment, water vapor will accumulate in the gap between the bonding surfaces and rust the cable. With the passage of time, the wire rope will rust and break, even cause the whole conveyor belt to break suddenly. It is understood that in 2006, Panjiang Coal and power company in Guizhou's Huopu mine occurred a steel rope conveyor belt fracture. This is because the local damage was repaired by a second rubber repair method. There is no problem with surface repair, but the paste area is concentrated. The corrosion caused by water vapor makes many steel cables break, which leads to the sudden fracture of conveyor belt, which leads to serious accidents.
另外,這種修復(fù)方法的成本也較高。
In addition, the cost of this repair method is higher.
(3)橡膠修補(bǔ)膠涂料的修補(bǔ)方法國內(nèi)外生產(chǎn)的橡膠修補(bǔ)膠是二組分聚氨酯膠。使用時(shí),將兩者倒在一起攪拌均勻,在一定時(shí)間內(nèi)填充待修補(bǔ)表面并固化,成為橡膠狀彈性體。固化時(shí)間通常為0.56小時(shí),這與固化過程中的環(huán)境溫度有關(guān)。固化的凝膠對傳送帶的表面具有良好的附著力,在測試室中的實(shí)驗(yàn)數(shù)據(jù)表明其可以達(dá)到6 kNm(180剝離強(qiáng)度)。因此,修復(fù)表面的粘合和密封效果非常好,并且不會有水蒸氣http://132.cn/氧化粘合表面上的導(dǎo)線。更有利的是其優(yōu)異的耐磨性,并且阿克倫的磨損值是橡膠的4-6倍。優(yōu)異的耐磨性是修復(fù)部分輸送機(jī)磨損的關(guān)鍵要求。簡而言之,此方法是修復(fù)鋼絲繩傳送帶局部磨損的更有效方法。
(3) Repair method of rubber repair adhesive the rubber repair adhesive produced at home and abroad is a two-component polyurethane adhesive. When in use, the two are poured together and stirred evenly, and the surface to be repaired is filled and cured within a certain period of time to form a rubber like elastomer. The curing time is usually 0.5 to 6 hours, which is related to the ambient temperature during the curing process. The solidified gel has good adhesion to the surface of the conveyor belt. The experimental data in the test room indicate that it can reach 6 kNm (180 peel strength). Therefore, the bonding and sealing effect of the repair surface is very good, and there is no water vapor http://132.cn/ Oxidize the wire on the bonding surface. The most favorable is its excellent wear resistance, and the wear value of Akron is 4-6 times that of rubber. Excellent wear resistance is the key requirement to repair part of the conveyor wear. In short, this method is the most effective method to repair the local wear of steel wire rope conveyor belt.
鋼絲繩傳送帶由于磨損而暴露在外。如果沒有密封和覆蓋,鋼絲繩可能會生銹并導(dǎo)致皮帶斷裂。為了延長其使用壽命,必須對其進(jìn)行維修。通過對大柳塔礦三種修復(fù)方法和修復(fù)實(shí)踐的比較,認(rèn)為橡膠修復(fù)膠涂層修復(fù)方法效果更好。
The wire rope conveyor belt is exposed due to wear. If not sealed and covered, the wire rope may rust and cause the belt to break. In order to prolong its service life, it must be maintained. Through the comparison of three repair methods and repair practice in Daliuta mine, it is considered that the rubber repair rubber coating method is the best.
