Description

A shaft continuous lifting equipment

technical field

The utility model belongs to the technical field of mine hoisting equipment for coal mining, and relates to a shaft continuous hoisting equipment including a hanging bucket, a roller, a belt and a belt conveyor, and is suitable for mine coal hoisting and transportation for shaft development.

technical background

Coal mine main shaft hoist is the main hoisting equipment for hoisting coal and gangue in the mine. It is responsible for the most important hoisting task in the mine and plays an important role in ensuring the continuous and stable production of the mine. Especially in recent years, with the continuous improvement of the level of mine mechanization and the output of a single working face, the shortcomings of the existing traditional lifting equipment and technology have become increasingly prominent, and the problems of lifting equipment and technological innovation need to be solved urgently.

In coal mines developed by vertical shafts, the hoisting container of the main shaft is generally a skip or a mine car. It is characterized by a large lifting capacity, but its lifting effect is poor in terms of continuity and selectivity. On the one hand, the lifting process takes a lot of time in coal loading, unloading and cleaning, and the single lifting cycle is long; on the other hand, the large capacity makes its selectivity poor, and when it is necessary to lift in batches due to differences in coal types, its The improvement efficiency is greatly reduced.

Utility model content

The utility model aims at the problems that the existing hoisting equipment of shaft development mines cannot realize continuous hoisting, long single hoisting period and low efficiency, etc., and proposes a new hoisting equipment for realizing continuous coal transportation and shaft hoisting. This equipment fixes the hanging bucket 4 on the refitted belt 3, and utilizes a new way of cooperating between the gear transmission and the belt transmission among the various lifting and transporting equipment.

A shaft continuous hoisting device, characterized in that:

(1) The lifting device includes a drum one 1 and a drum two 2 . Drum one 1 is installed on the ground, is driving drum, applies rotational moment, and installation height is higher than ground belt conveyer 6 distances more than three hanging buckets 4. Drum two 2 are installed in the bottom of the well, and are driven drums, which are used for hanging bucket 4 reversing.

(2) The modified belt 3 is wound on the two drums 1 and 2, and the hanging bucket 4 is triangularly welded on the modified belt 3 in turn, and a certain safety distance is left between the two hanging buckets 4. The number and capacity of 4 hanging buckets depend on the depth of the shaft.

(3) The belt conveyor 6 is installed on the right side of the drum one 1 to accept the unloaded coal from the side of the hanging bucket 4 and further transport it to the coal preparation plant.

The new lifting equipment of the utility model is quite different from the general existing shaft skip lifting, which is mainly manifested in the following aspects:

(1) The utility model has good lifting and transportation continuity, high efficiency and reliability, and can better realize the effect of coal loading and lifting by different coal types, while the traditional shaft skip lifting cannot realize coal loading and lifting by different coal types, and single lifting The time is long and the continuity is poor, so it is difficult to meet the needs of safe, economical and efficient mine production. The utility model is equivalent to changing the lifting of a single skip into a plurality of small hanging buckets, which has a large lifting capacity, and realizes the continuous lifting of different types of coal simply and easily, and can also greatly reduce the workload of coal washing.

(2) The hanging bucket 4 of the hoisting equipment of the utility model realizes reversing when passing through the second position of the bottom shaft drum, and becomes the opening upward, and the movable coal retaining plate 7 is automatically opened under the action of gravity, and the unloaded hanging bucket 4 follows Coal loading is carried out when the modified belt 3 moves to the coal outlet 5. After the coal loading is completed, it continues to move upward under the pulling force of the modified belt 3. When it reaches the upper apex of the ground drum 1, the movable coal retaining plate 7 Automatically shuts off. At the same time, the hanging bucket 4 changes direction, and the coal outlet 5 faces downward. Under the action of gravity, the coal in the hanging bucket 4 is unloaded downward along the inclined surface of the movable coal retaining plate 7 until the unloading is completed. The hanging bucket 4 continues to move to the bottom of the well with the modified belt 3 to repeat the above actions, and each hanging bucket 4 is loaded and unloaded according to the above steps;

(3) The equipment of the utility model has wide practicability. It utilizes a plurality of hanging buckets 4 to run along with the refitted belt 3 to realize the continuous lifting of coal. , the utility model can bring great economic benefits to mine lifting and transportation, and promote the realization of safe and efficient production in mines;

(4) The utility model is suitable for lifting and transporting coal in mine shafts, especially when the underground coal output is very large.

Detailed ways

The entire lifting and transportation process of the utility model is specifically implemented as follows:

(1) As shown in Figure 1, it is a schematic structural diagram of the lifting equipment. The assembly and matching process of each equipment part is as follows: the modified belt 3 is wound on the first drum 1 and the second drum 2, and the hanging bucket 4 is suspended on the triangle welding point 11 in turn. up, and along the running direction 10 opening of the modified belt 3 to realize the lifting operation upward; install the hinged coal retaining plate 7 and the welded coal retaining plate 8 on the hanging bucket 4, and the gears on the first drum 1 and the second drum 2 and the modified belt 3 are mutually Engagement; the drum one 1 is connected with the dynamic power device. Thus, the mutual operation of the entire set of equipment is realized; the belt conveyor 6 is arranged on the right side of the running direction of the refitted belt 3 to receive the coal lifted by the hanging bucket 4 and transport it to the coal preparation plant.

(2) As shown in Figure 2, it is a three-dimensional perspective view of the hanging bucket 4 of the lifting equipment in the utility model. There is a triangular welding point 11 on the back of the hanging bucket 4 that matches the modified belt 3, and the hinged coal retaining plate is directly above the hanging bucket 4. 7 and welding coal retaining plate 8, when hinged coal retaining plate 7 rotates to welding coal retaining plate 8, just in time completely covers hanging bucket 4 front, hinged coal retaining plate 7 is blocked by welding coal retaining plate 8, does not rotate.

(3) As shown in Figure 3, for the refitting belt 3 of the hoisting device, a tooth hole 9 is installed on the refitting belt 3 of 100 mm, meshed with the first drum 1 and the second drum 2, and the triangular joint point 11 is welded in the middle of the belt, Cooperate with hanging bucket 4.

(4) As shown in FIG. 4 , which is a schematic diagram of loading of the lifting device, the refitted belt 3 moves upward while the coal outlet 5 discharges coal and loads it into the hanging bucket 4 .
