Abstract
The utility model discloses an unloading pit connecting an unloading chamber and a drop shaft. The bottom of the unloading pit adopts a flat bottom structure, so that a blind stock heap is formed, direct impact and abrasion to the unloading pit from materials are reduced, and the speed of the materials is lowered. A central material dropping structure is arranged, the materials are gathered, direct impact and damage to the drop shaft are reduced, and the drop shaft is well protected. The unloading pit is of a flat-bottom structure, the blind stock heap is formed when the materials pass through the bottom of the unloading pit, and the unloading pit is protected against direct impact and damage. The central material dropping structure is arranged at the bottom of the unloading pit, the materials are gathered, and the drop shaft at the lower portion is prevented from being directly impacted by the materials. The impact and abrasion strength of the central material dropping structure is improved, and the inner wall and the upper end surface of the central material dropping structure are provided with abrasion-resistant lining plates. As the central material dropping structure is arranged on the unloading pit at the upper portion of the opening of the drop shaft, the defect that the materials directly impact and abrade the unloading pit and the drop shaft is avoided, and the service life of the drop shaft is prolonged.
Description
Technical field
The utility model relates to a kind of mining drop shaft system, is specifically related to a kind of hole and structure with drop shaft junction of unloading.
Background technology
Drop shaft system is that underground mine is produced one of most important mining engineering, the material of underground mining collects storage and transhipment thus, whether unimpeded stablizing of it be very big to mine Influence of production, produce once destroy not only impact, and the safety that threatens whole drop shaft system and main shaft.Drop shaft system generally comprises unloading chamber, drop shaft, ore storage bin and bottom feed chamber etc.Due to drop shaft engineering-environment complexity, the load that is hit for a long time again, the large and soft broken mine of ore deposit rock of some production capacity all exists drop shaft gross distortion to destroy problem.Destruction the lighter need stop production and reprocess for a long time, and severe patient pit shaft is scrapped, and produces and has caused huge economic loss to mine.The failure mechanism of further investigated drop shaft, the thin portion of the effective drop shaft of reasonable structure, directly impacts and wearing and tearing drop shaft to reduce material, to ensureing that normal production of mine safety is extremely important.Unloading chamber unloading hole is structure of drop shaft system topmost, the general inclined-plane that adopts, bottom, unloading hole at present, and unloading hole is identical with drop shaft section with drop shaft coupling part section, and this structure makes material impact destruction to drop shaft wall.
Utility model content
The purpose of this utility model is to provide a kind of and converges material, avoids drop shaft to avoid the unloading hole structure of the direct impact failure of material.
The unloading hole of the disclosed this connection unloading chamber of the utility model and drop shaft, this unloading hole forms dead ore deposit heap while material being fallen for flat-bottom structure, be provided with central blanking structure and converge material to reduce the direct impact failure of material to drop shaft on flat-bottom structure.
Described central blanking structure adopts reinforced concrete structure, and its diameter is less than drop shaft diameter.
Inwall and the upper surface of described central blanking structure are provided with abrasion-proof backing block.
The diameter d of described central blanking structure is at least 3 times of the maximum lumpiness of material.
The height of described central blanking structure is at 1m ~ 4m.
The bottom that the utility model is cheated unloading adopts flat-bottom structure, forms dead ore deposit heap, and direct impact and the wearing and tearing that minimizing material is cheated unloading also slow down material speed; Central blanking structure is set, converges material and reduce the direct impact failure of drop shaft, well protect drop shaft.The diameter of central blanking structure is less than drop shaft diameter, material is converged and avoid bottom drop shaft to suffer the direct impact wear of material.The intensity that suffers material wearing and tearing in order to strengthen central blanking structure, wall and upper surface arrange abrasion-proof backing block therein.
The utility model arranges in the unloading hole on drop shaft mouth top the central blanking structure that diameter is less than drop shaft diameter, has avoided the defect of prior art material direct impact wear unloading hole and drop shaft, thereby extends the application life of drop shaft, and cost uses manpower and material resources sparingly.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of prior art.
Detailed description of the invention
As shown in Figure 1, the unloading hole 2 of the disclosed this connection unloading chamber 1 of the utility model and drop shaft 6, establishes with drop shaft 6 connecting portions the central blanking structure 4 that a diameter is less than drop shaft 6 diameters in 2 bottoms, unloading hole.Unloading hole 2 is flat-bottom structure, forms dead ore deposit heap 3, and dead ore deposit heap 3 has protected unloading hole 2 to avoid the direct impact wear of material.Central blanking structure 4 converges material 7 and reduces the direct impact to drop shaft 6.Central blanking structure 4 adopts reinforced concrete structure, suffers the intensity of material wearing and tearing in order to strengthen central blanking structure 4, and wall and upper surface arrange abrasion-proof backing block 5 therein.
The internal diameter of central blanking structure 4 and highly all definite according to the cohesiveness of material and lumpiness.In order to prevent blockage phenomenon in blanking process, the internal diameter that should ensure central blanking structure 4 is maximum the more than 3 times or 3 times of lumpiness of material, and height h is generally 1m ~ 4m.
Claims (5)
1. one kind connects the unloading hole of unloading chamber and drop shaft, it is characterized in that: this unloading hole forms dead ore deposit heap while material being fallen for flat-bottom structure, is provided with central blanking structure and converges material to reduce the direct impact failure of material to drop shaft on flat-bottom structure.
2. the unloading hole of connection unloading chamber as claimed in claim 1 and drop shaft, is characterized in that: described central blanking structure adopts reinforced concrete structure, and its diameter is less than drop shaft diameter.
3. the unloading hole of connection unloading chamber as claimed in claim 1 and drop shaft, is characterized in that: inwall and the upper surface of described central blanking structure are provided with abrasion-proof backing block.
