Embodiment 1
[0025] The utility model relates to a test device for simulating ore drawing at the bottom of a chute. Such as figure 1 As shown, the test device includes a platform 1 , a base 2 , a chute 5 and an ore-drawing composite plate 7 . The four corners of the lower plane of the platform 1 are respectively fixed with bases 2, the platform 1 is provided with a chute 5, and the bottom of the chute 5 is provided with an ore-drawing composite plate 7.
[0026] Such as figure 1 As shown, the platform 1 is a rectangular steel plate hollowed out in the middle, and the hollowed out area in the middle is a square, and horizontal strip-shaped through holes 6 are symmetrically arranged on both sides close to the hollowed out area, and two parallel beams 4 are arranged in the hollowed out area. The two ends of the two parallel beams 4 are close to the upper plane of the platform 1, and the two ends of the two parallel beams 4 are fixedly connected to the platform 1 through the bolts in the cor...

The invention relates to a test device for simulating ore pass bottom ore drawing. According to the technical scheme, the two ends of two parallel cross beams (4) are fixedly connected with the upper plane of a platform (1) through bolts in corresponding horizontal bar-shaped through holes (6) in both sides; bases (2) are fixed at four corners of the lower plane of the platform (1); two dual-end bolts (3) are symmetrically arranged in vertical bar-shaped through holes in the bases (2) on the same side; an ore-drawing composite plate (7) consists of an adaptive plate (10), bar-shaped special-shaped slide plates (9) and a movable plate (11); the movable plate (11) is movably arranged in a bar-shaped sliding chute formed by the adaptive plate (10) and the two bar-shaped special-shaped slide plates (9); two bar-shaped slide rails (8) are movably arranged in slide ways on the lower planes of the two bar-shaped special-shaped slide plates (9); the two bar-shaped slide rails (8) are fixed at the middle positions of the two dual-end bolts (3); a shaft (13) of an ore pass (5) is placed on the upper planes of the cross beams (4); the lower end port of an ore drawing hopper (14) is tightly attached to an ore-drawing hole of the adaptive plate (10). The test device has the characteristics of wide application range, convenience in operation, high practicability and simple structure.
Description
technical field [0001] The invention belongs to the field of chute test simulation. Specifically relates to a test device for simulating ore drawing at the bottom of a chute. Background technique [0002] The mine shaft is an important channel for ore transportation, and its operation status directly affects the safe and stable production and economic benefits of the mine. After the ore is unloaded into the chute, there are mainly two transportation methods: chute and ore drawing. During the ore drawing process, the ore and the shaft wall frequently rub against each other, causing the shaft wall to be worn and damaged. Influenced by the physical and mechanical properties of ore and shaft wall materials, blockages and ore failures often occur in the chute. These failures not only affect the safe and continuous production of the chute, but also the troubleshooting work is laborious, difficult and dangerous. In the design or use stage of the chute, if the ore migration chara...
