In order to apply to the rail laying form of adding wrong carriageway, the wheels of the rear unloading inclined shaft skip car and counterweight I can be changed from flat wheels to grooved wheels to control the wrong direction, and the other side is flat wheels to facilitate crossing turnout and unloading curved rails.
The traction device of skip tramcar and counterweight is fixed and connected, and Babbitt alloy is used for pouring. And the pulling rope is about 100mm away from the center line of the skip, so that two wire ropes do not collide. When the skip or counterweight passes through the turnout, use the idler and vertical roller to reduce the traction angle. Generally, it will not produce too much lateral force within 7 °, which will not affect the operation of the skip and counterweight. The traction wire rope 10 m from the front of the skip shall fall below the rail surface into the groove of the rope supporting pulley.
In order to prevent the traction wire rope of the lower skip from rubbing with the steel rail and being rolled by the wheel of the rising counterweight, the rope groove, vertical roller and carrier roller shall be set at the turnout of the middle section passing the lane, and the carrier rope wheel shall be set on the monorail line.
In order to improve the skip filling coefficient, a cover plate of appropriate length can be added at the upper mouth of the skip.
At present, there are many kinds of trams for ore transportation in domestic mines, and large and medium-sized mines tend to use bottom dump and bottom side dump trams for transportation. Compared with other types of tramcars, these two types of tramcars can realize continuous loading and unloading
