1. Improve the chute of conveyor belt. Improving the hopper of conveyor belt is one of the effective measures to prevent the early damage of conveyor belt. The hopper at the transition of each belt conveyor is improved to increase its ability to pass through foreign matters by 2.5 times. Long and large foreign matters are not easy to get stuck between the funnel wall and the conveyor belt in the conveying process, so as to reduce the probability of foreign matters tearing the conveyor belt. The guide apron at the hopper makes the gap between it and the conveyor belt larger and larger along the running direction of the conveyor belt, so as to solve the problem that the coal block and stone block are stuck between the conveyor belt and the apron and eliminate the damage of the conveyor belt caused thereby. For hopper with large drop, buffer baffle shall be installed inside to avoid direct impact of materials on conveyor belt.

2.在改向滾筒處加刮料裝置。在輸送帶沿線的改向滾筒處加設(shè)刮料裝置，改向滾筒處物料粘結(jié)問題，解決因滾筒粘料引起的輸送帶局部破損。

2. Add scraping device at the reversing drum. A scraping device is added at the diversion drum along the conveyor belt to eliminate the problem of material adhesion at the diversion drum and solve the local damage of the conveyor belt caused by the roller sticking.

3.輸送機(jī)頭、尾及中間轉(zhuǎn)載過渡處的改進(jìn)。輸送機(jī)頭、尾及中間轉(zhuǎn)載處的過渡長(zhǎng)度及過渡方式，對(duì)輸送帶的使用壽命影響很大。須進(jìn)行合理的過渡設(shè)計(jì)，應(yīng)盡量減輕輸送帶膠面的磨損，確保不出現(xiàn)輸送帶的折疊、中間凸起現(xiàn)象，落料處不出現(xiàn)物料撒漏。

3. Improvement of conveyor head, tail and intermediate transfer transition. The transition length and transition mode of conveyor head, tail and middle transfer have great influence on the service life of conveyor belt. A reasonable transition design shall be carried out to minimize the abrasion of the rubber surface of the conveyor belt, so as to ensure that there is no folding and middle bulge of the conveyor belt, and there is no material leakage at the dropping place.

4.輸送機(jī)在凹過渡處的壓帶輪。實(shí)踐證實(shí)，鋼繩式輸送帶橫向強(qiáng)度不足，啟動(dòng)時(shí)，壓帶輪造成輸送帶局部受力過大，導(dǎo)致撕裂輸送帶，將壓帶輪全部改為壓帶滾筒，可徹底解決這一問題。

4. Belt pulley of conveyor at concave transition. Practice has proved that the transverse strength of the steel rope conveyor belt is insufficient. When the belt is started, the pressure pulley causes the local stress of the conveyor belt to be too large, which leads to the tearing of the conveyor belt. The problem can be completely solved by changing the pressure pulley into the pressure pulley.

5.大機(jī)臂架輸送帶配重減載。煤礦系統(tǒng)堆場(chǎng)堆料機(jī)臂架輸送帶更初使用壽命很短，配重設(shè)計(jì)過重是造成輸送帶張力過大，過早龜裂老化的重要原因。在滿足輸送帶運(yùn)載物料張力的基礎(chǔ)上，減輕配重后，運(yùn)送煤炭由150萬(wàn)t的使用壽命延長(zhǎng)到450萬(wàn)t。20萬(wàn)t礦用系統(tǒng)堆取料機(jī)臂架輸送帶原設(shè)計(jì)配重為25t(含配重滾筒重量)，原裝德國(guó)進(jìn)口抗撕裂鋼絲帶作業(yè)不到300萬(wàn)t就嚴(yán)重拉伸報(bào)廢，經(jīng)兩次減載降低6t配重后，使用國(guó)產(chǎn)普通鋼絲帶，作業(yè)量超過800萬(wàn)t。

5. Load reduction of boom conveyor belt balance. The initial service life of the boom conveyor belt of the stacker in the coal mine system is very short, and the overweight of the counterweight design is an important reason for the excessive tension and premature cracking and aging of the conveyor belt. On the basis of meeting the tension of the material carried by the conveyor belt and reducing the counterweight, the service life of the transported coal is extended from 1.5 million T to 4.5 million T. The original design weight of the boom conveyor belt of the 200000 t mining system stacker reclaimer is 25t (including the weight of the counterweight drum), and the original German import tear resistant steel wire belt is severely stretched and scrapped when it is less than 3 million T. after twice load reduction and 6 t counterweight reduction, the domestic common steel wire belt is used, and the operation volume is more than 8 million T.

6.料流方向調(diào)整。料流方向?qū)斔蛶У氖褂脡勖哂兄匾绊懀瑧?yīng)使物料流與輸送帶同方向運(yùn)行，可大大提高設(shè)備使用壽命。

6. Adjust the direction of material flow. The direction of material flow has an important influence on the service life of the conveyor belt. The material flow should be operated in the same direction as the conveyor belt, which can greatly improve the service life of the equipment.

7.輸送帶局部損傷修復(fù)技術(shù)延長(zhǎng)使用壽命。(1)局部熱硫化；(2)局部冷潑，產(chǎn)品有美國(guó)福世藍(lán)(1st line)技術(shù)液體高分子復(fù)合修復(fù)材料、德國(guó)德?？档龋璩毓袒?0h左右；(3)局部冷粘，采用德國(guó)蒂普拓普公司修補(bǔ)條(縱向裂口)、冷粘膠一T2復(fù)合膠縱向填補(bǔ)裂縫堵(需專用膠槍)。這兩種方法優(yōu)點(diǎn)是人力物力投人較少，具有較好的耐磨損和補(bǔ)強(qiáng)性能，恢復(fù)時(shí)間較短，缺點(diǎn)是對(duì)環(huán)境的要求高，不能恢復(fù)到原輸送帶表面平整要求；(4)輸送帶噴涂修復(fù)技術(shù)。該技術(shù)是將幾種液體材料經(jīng)專用設(shè)備混合，高壓噴到皮帶磨損表面，根據(jù)需要噴涂一定厚度的耐磨層。固化時(shí)間短，適用于連成片的局部磨損，效果很好，缺點(diǎn)是需要專用設(shè)備。

7. The local damage repair technology of conveyor belt extends the service life. (1) Local hot vulcanization; (2) local cold splashing, the products include the first line technology liquid polymer composite repair material, Germany defukang, etc., but it needs to be cured at room temperature for about 10h; (3) local cold bonding, the repair strip (longitudinal crack) of Germany tippop company, cold adhesive T2 composite adhesive are used to fill the crack (special glue gun is required). The advantages of these two methods are less manpower and material investment, better wear resistance and reinforcement performance, short recovery time, high environmental requirements, unable to restore to the original conveyor surface flatness requirements; (4) conveyor belt spray repair technology. The technology is to mix several liquid materials with special equipment, spray them to the worn surface of the belt under high pressure, and spray a certain thickness of wear-resistant layer as required. The curing time is short, which is suitable for the local wear of the continuous chips. The effect is very good. The disadvantage is that special equipment is needed.

8.合理選擇皮帶類型與維護(hù)。合理選擇類型，根據(jù)季節(jié)變化及時(shí)調(diào)整沿線糾偏裝置，加防曬罩以及冬季維護(hù)等措施亦可延長(zhǎng)輸送帶壽命。

8. Reasonably select belt type and maintenance. Reasonable selection of type, timely adjustment of deviation rectifying device along the line according to seasonal changes, adding sunscreen, winter maintenance and other measures can also extend the life of conveyor belt.

9.其他管理問題。加強(qiáng)托輥及清掃器管理，損壞要及時(shí)更換?？刂茙лd啟動(dòng)。

9. Other management issues. Strengthen the management of idler and cleaner, and replace the damaged ones in time. Control on load start.
