①在所有安置带式输送机的巷道最低洼处增大托辊架密度，即在每个托辊架间增加2个托辊架，以减小此处托辊架跨距，输送带运送煤矸经过低洼处不再下垂于托辊架空内。
(1) increasing the density of the roller frame in the lowest depressions
of all the belt conveyors, that is, adding 2 rollers between each
roller frame to reduce the span of the roller frame here, and the
conveyer belt is no longer drooping in the roller overhead through the
low-lying areas.
②在托辊架上焊接几个加固支架，各焊接口采用补焊来增加托辊架强度；在安放托辊的槽口上方增设挂耳钩环来固定托辊，使托辊不会被砸下。
Secondly, several reinforcement supports are welded on the roller frame,
and the welding joints are www.zhadai.org.cn www.xiaoyuandiaos.cn
www.tongfoxiang.net.cn www.tongfengji.net.cn www.shidiaoshizi.com.cn
www.jianchajingmuju.cnwelded to increase the strength of the roller
frame; the hooked ring is added above the slot of the placement rollers
to fix the rollers so that the rollers will not be smashed.
③制作4个U形环，把拉紧小车的4个角固定在钢轨上，防止其上下跳动和左右摆动，避免掉道，但不妨碍前后移动，既不影响根据工况调整输送带张紧力，也不影响拉紧装置正常工作。
(3) making 4 U rings to fix the 4 corners of the pulling trolley on the
rail to prevent it from jumping up and down and swinging left and right
and avoiding the path, but it does not interfere with the movement of
the front and back, neither affects the tension of the conveyor belt in
accordance with the working condition, nor does it affect the normal
work of the tightening device.
④所有给煤机卸料口重新更换卸料斗，并倾斜一定角度，在其下部增设缓冲件，大块煤矸不再直接砸在输送带上，减少其对输送带的冲击力。
All the unloading ports of the coal machine are replaced by the
replacement hopper, and a certain angle is inclined, and the buffer
parts are added in the lower part. The large coal gangue is no longer
directly smashed on the conveyer belt to reduce its impact on the
conveyor belt.
