Most of the conveying mechanisms below the ground of the coal mine are arranged in the condition that the conveying belt lines in the roadway are staggered, which will lead to the abnormality of material transportation conflict. Therefore, improving the composition of the belt conveyor and increasing and lengthening its specification can ensure the effect of cross track effective work on the premise of normal locomotive transportation. The specific scheme is as follows:

在主運巷內(nèi)并行鋪設(shè)工作軌道和皮帶機線體，并在現(xiàn)有軌道側(cè)構(gòu)建另一條遠(yuǎn)距離皮帶機，該機需跨軌道與主運巷機體搭接，所以需在該機機端安裝加長卸載斗，設(shè)計初衷結(jié)構(gòu)簡單、拆裝方便、穩(wěn)定性強，使之卸載裝置可順利跨越下部軌道，保證每條線體運送時互不干涉；

The working track and belt conveyor line are laid in parallel in the main transport lane, and another long-distance belt conveyor is built on the side of the existing track. The machine needs to cross the track and overlap with the main transport lane body, so it is necessary to install an extended unloading bucket at the machine end of the machine. The original design intention is simple structure, convenient disassembly and strong stability, so that the unloading device can smoothly cross the lower track, Ensure that each line body does not interfere with each other during transportation;

經(jīng)實測驗證，所用皮帶機卸載裝置理論高度，可據(jù)機車外形尺寸將卸載機的下沿距軌道的高度加以提升，為其他的軌道運送騰出空間，為保證卸載長度，皮帶機加長段需確保充足的橫向尺寸供機車通行，當(dāng)把加長段調(diào)整為理論數(shù)值后，整個加長卸載裝置就可與運巷輸送機順利接軌，為便于運輸和安裝可將加長段設(shè)成兩段，每段間由剛性板和螺栓聯(lián)接，同時為保證穩(wěn)定性，在加長段間增設(shè)拉梁即可，采用槽鋼為框架，焊接上皮帶機機身縱梁管后，所安裝的緩沖托輥組及其支架就可以承受煤礦物料的沖擊；

According to the actual measurement and verification, the theoretical height of the unloading device of the belt conveyor can be raised from the lower edge of the unloader to the track according to the overall dimensions of the locomotive, so as to make room for other track transportation. In order to ensure the unloading length, the extension section of the belt conveyor needs to ensure sufficient transverse dimensions for the passage of the locomotive. When the extension section is adjusted to the theoretical value, The whole extended unloading device can be smoothly connected with the roadway conveyor. In order to facilitate transportation and installation, the extended section can be set into two sections. Each section is connected by rigid plates and bolts. At the same time, in order to ensure stability, pull beams can be added between the extended sections. Channel steel is used as the frame, and the longitudinal beam pipe of the upper belt conveyor body is welded, The installed buffer idler group and its support can withstand the impact of coal mine materials;

另外在卸載料端采用皮帶輸送機的標(biāo)準(zhǔn)卸載機構(gòu)，既可簡化加工量，又可與帶式輸送機的標(biāo)準(zhǔn)件通用，利用皮帶機機頭頂所用的連接孔，該孔設(shè)有由對稱的兩片墊架所組成的加高架，能夠滿足機車通過的要求，墊架上下部通過螺栓與機頭連接，上部與加長段連接，以使得加長卸載裝置與皮帶機機頭組合為整體，考慮到橡膠傳送帶通過時坡度大，無法平緩運卸煤，且皮帶與加高卸載裝置間不能干涉，為保證穩(wěn)定及可靠性，我們可通過布置線性加高的托輥支架，固定在皮帶機機頭及其折返架上，可起到橡膠皮帶平緩運送的效果；

In addition, the standard unloading mechanism of the belt conveyor is adopted at the unloading end, which can not only simplify the processing volume, but also be common with the standard parts of the belt conveyor. The connecting hole used at the top of the belt conveyor is used. The hole is provided with a raised frame composed of two symmetrical cushion frames, which can meet the requirements of the passing of the machine and vehicle. The upper and lower parts of the cushion frame are connected with the head through bolts, and the upper part is connected with the extension section, In order to combine the extended unloading device with the belt conveyor head as a whole, considering the large slope when the rubber conveyor belt passes through, it is impossible to transport and unload coal smoothly, and there is no interference between the belt and the heightening unloading device, in order to ensure stability and reliability, we can arrange the linearly heightening idler support and fix it on the belt conveyor head and its turn back frame, It can have the effect of smooth transportation of rubber belt;

由于加長段的跨度尺寸大，普通小型皮帶輸送機的斜支撐則無法承受其載荷，因此在卸載端下可設(shè)成帶有地腳固定的支腿，并通過斜拉梁來共同支撐整個加長后的卸載機構(gòu)，但是由于膠帶機運轉(zhuǎn)中振動比較大，會導(dǎo)致卸載位置偏離、穩(wěn)定性低的不足，可增設(shè)吊掛孔及高強鏈的方式將卸載裝置固定到頂板上，可實現(xiàn)緩沖吸振、確保卸載位準(zhǔn)確的效果，環(huán)形橡膠皮帶通過逐級加高的緩沖托輥組后可平順地過渡到加長卸載裝置，再經(jīng)加長段步入皮帶機線體卸載臂，待卸料后經(jīng)改向滾筒，由V型調(diào)心托輥支架組等運送到機體的包膠電動滾筒端，完成輸送規(guī)格經(jīng)加長后的循環(huán)工作過程；

Due to the large span size of the extended section, the inclined support of ordinary small belt conveyor can not bear its load. Therefore, the outrigger with fixed foundation can be set under the unloading end, and the whole extended unloading mechanism can be supported together through the inclined beam. However, due to the large vibration during the operation of the belt conveyor, the unloading position will deviate and the stability will be low, The unloading device can be fixed to the top plate by adding hanging holes and high-strength chains, which can achieve the effect of cushioning and vibration absorption and ensure the accuracy of unloading position. The annular rubber belt can smoothly transition to the extended unloading device after passing through the buffer idler group increased step by step, and then enter the line unloading arm of the leather belt machine through the extended section. After unloading, it will be changed to the drum, The V-shaped self-aligning idler support group is transported to the rubber coated electric roller end of the machine body to complete the cyclic working process after the conveying specification is extended;
