胶带运输机(以下简称胶带机)以其许多优点,在国内外冶金、矿山、化工、电力等部门获得了日益广泛的应用,随着我国煤矿机械化程度的提高,胶带机已成为井下运输的主要设备。因此,作为转载部位的受煤架在运输系统中处于比较重要的地位,不仅阻挡落料时物料外溢,提高运输效益,减少巷道的清煤量,而且还减缓物料对胶带的冲击力,延长胶带寿命。 根据目前的运输系统,受煤架种类按机型可分胶带机与胶带机、胶带机与刮板运输机两种。按相对位置分平行型、垂直型和其它型(如图1 a、b、c),按受煤架安装位置又可分中间和尾部两种形式。 受煤架在频繁的物料冲击下,损坏严重,使用寿命短,需经常维修更换,加之原结构为整体焊接型,体积1700×1200×1200mm,重量300kg,故井下运输、安装、维修极不方便。为此,我矿将受煤架改为分开组合式,即可折式结构(如图2),我矿20多台胶带机使用效果很好,很受欢迎。 支架与支架之间,支架与护板之间,支架与钢丝绳(或钢管)之间均采用螺栓联结或绳卡(或U型螺栓)固定,拆装方便、迅速。支架采用75×75×8角铁(如图3示)。 拉杆改原100×100×10角钢为φ24～28圆钢(如图4示);绳卡用于落地架式胶带机的 Tape conveyor (hereinafter referred to as tape machine) with its many advantages in the metallurgical, mining, chemical, power and other departments at home and abroad have been increasingly widely used, with the degree of mechanization of coal mines in our country, the tape machine has become the main equipment for underground transportation . Therefore, as the transfer part of the coal frame in the transport system is in a more important position, not only to prevent material spillage blanking to improve transport efficiency and reduce the amount of coal in the roadway, but also slow down the impact of materials on the tape, tape extension life. According to the current transport system, depending on the type of coal briquette machine can be divided into tape and tape machines, tape machines and scraper conveyor two. According to the relative position sub-parallel type, vertical type and other types (Figure 1a, b, c), according to the installation position by the coal frame can be divided into two kinds of middle and tail. Under the frequent impact of material, the coal frame is damaged severely and has a short service life. It needs frequent maintenance and replacement. In addition, the original structure is welded as a whole, with a volume of 1700 × 1200 × 1200mm and a weight of 300kg. Therefore, it is extremely inconvenient for transportation, installation and maintenance in the well . To this end, I mine will be replaced by a separate coal frame unit, which can be folded structure (Figure 2), mine more than 20 tape machine with good results, very popular. Between the bracket and the bracket, between the bracket and the guard, between the bracket and the wire rope (or steel pipe) are bolted or rope (or U-bolt) fixed, easy disassembly and rapid. Bracket with 75 × 75 × 8 angle iron (shown in Figure 3). Lever to change the original 100 × 100 × 10 angle φ24 ~ 28 round bar (shown in Figure 4); Rope card for floor rack tape machine
