1、緩沖托輥
1. Buffer idler
為防止輸送帶受到過大的沖擊力,在投料部位應(yīng)設(shè)置緩沖托輥(膠輪或小型輪胎),托輥要轉(zhuǎn)動自如。
In order to prevent the conveyor belt from being subjected to excessive impact force, buffer idlers (rubber tires or small tires) should be set at the feeding position, and the idlers should rotate freely.
2、 擠膠
2. Extrusion
為防止物料嚙入擠咬損壞膠帶,在托輥和返回輥之間設(shè)置1—2毫米厚的鐵板隔板和刮板。
In order to prevent the material from biting into the belt, a 1-2 mm thick iron plate partition and scraper are set between the idler and return roller.
3、 滾筒上塊狀附著物防止措施
3. Prevention measures of block attachment on drum
與上蓋膠接觸的滾筒上,附著物容易堆積成塊,這就改變滾筒半徑,致使輸送帶上鋼絲繩張力不平衡若輸送帶繼續(xù)運行,則會導(dǎo)致部分鋼絲繩斷裂事故的發(fā)生。因此為防止附著物堆積成塊,必須在帶輪上安裝好清掃裝置,尤其是頭部和尾部的清掃裝置更要完備。
On the drum in contact with the upper cover rubber, the attachments are easy to accumulate into blocks, which will change the drum radius and cause the tension imbalance of the steel wire rope on the conveyor belt. If the conveyor belt continues to run, it will lead to some wire rope fracture accidents. Therefore, in order to prevent the attachment from accumulating into blocks, the cleaning device must be installed on the pulley, especially the head and tail cleaning device should be more complete.
4、 頭部和尾部成槽角
4. Groove angle of head and tail
鋼絲繩芯輸送帶的成槽性能良好,成槽和頭部和尾部輥筒之間的成槽角往往變化很急劇,此時輸送帶邊部張力大,容易引起邊膠異常磨損傷輥筒近處的托輥,也能引起鋼絲繩斷裂事故。為避免上述事故,把帶輪近處的幾組托輥的成槽角逐漸減少,以使成槽角變化緩慢。

The grooving performance of steel cord conveyor belt is good, and the groove angle between groove forming and head and tail roller often changes rapidly. At this time, the edge tension of conveyor belt is large, which is easy to cause abnormal wear of edge glue and damage to the roller near the roller, as well as wire rope fracture accident. In order to avoid the above accidents, the groove angle of several groups of idlers near the pulley is gradually reduced to make the groove angle change slowly.
5、輸送帶上升或下降彎曲點時,該處產(chǎn)生張力和壓力的異常,容易使輸送帶邊膠異常磨損,也能引起鋼絲繩斷裂。為避免這些事故,彎曲點處曲率半徑盡可能要大,托輥的成槽角應(yīng)小些,其配置也應(yīng)密一些才好。
5. When the conveyor belt goes up or down the bending point, the tension and pressure will be abnormal, which will easily cause the abnormal wear of the belt edge glue, and also cause the wire rope to break. In order to avoid these accidents, the curvature radius at the bending point should be as large as possible, the groove angle of the idler should be smaller, and its configuration should be more dense.
6、鋼絲繩芯輸送帶縱裂事故是難解決的問題,采用防撕裂型鋼絲繩芯輸送帶,可以起到一定的效果,但仍需徹底搞好日常保養(yǎng)管理,才能防止縱裂事故,以下列出幾項防縱裂措施:
6. However, the following measures can be taken to prevent longitudinal crack of conveyor belt
(1) 輸送機(jī)裝載段是輸送帶縱向撕裂多發(fā)區(qū),特別是轉(zhuǎn)載漏斗的溜槽出口處。因此,是預(yù)防輸送帶發(fā)生撕裂的重要環(huán)節(jié)??稍谠撎幯b設(shè)擺動梭式分離裝置和溜槽斜格篩,以分離大塊長件物料。
(1) The loading section of conveyor is the area where longitudinal tearing of conveyor belt occurs, especially at the outlet of chute of transfer hopper. Therefore, it is an important link to prevent the conveyor belt from tearing. Swing shuttle type separation device and chute inclined grid screen can be installed here to separate large and long materials.
(2) 在物料進(jìn)入輸送帶之前的輸送環(huán)節(jié)上加裝電磁除鐵器感應(yīng)信號裝置,作為防撕裂的一道關(guān)口。
(2) The induction signal device of electromagnetic iron remover is installed on the conveying link before the material enters the conveyor belt, as a pass to prevent tearing.
(3) 改善溜槽通過能力,增加溜槽通過高度,溜槽內(nèi)隱患。
(3) Improve the capacity of the chute, increase the height of the chute, and eliminate the hidden danger in the chute.
(4) 在膠帶卸料滾筒之前,漏斗之上部位設(shè)置防止膠帶被鐵件撕裂的防護(hù)板,防止鐵器與膠帶直接接觸造成膠帶劃破。
(4) Before the belt unloading drum, a protective plate is set on the upper part of the funnel to prevent the belt from being torn by the iron parts, so as to prevent the iron ware from directly contacting with the belt and causing the belt to be scratched.
