Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

As shown in FIG. 1, before the down pipe body 1 is replaced and installed, the lower end connector of the upper down pipe needs to be ensured to be the same as the lower connector 3 in the patent.

During connection, the upper connecting pipe head 2.1 is directly sleeved on the lower connecting pipe head 3.4 on the upper part of the disassembling sleeve 3.7, and the inclined plastic column 3.5 is inclined upwards, so the upper connecting pipe head 2.1 is rubbed by the inclined plastic column 3.5 after being sleeved and taken, and is difficult to move downwards, at the moment, the upper connecting pipe head 2.1 only needs to be continuously moved upwards towards the previous blanking pipe until the upper connecting method disc 2.2 is abutted against the lower connecting method disc 3.3 of the previous blanking pipe, and the upper connecting pipe head 2.1 and the whole blanking pipe are adjusted according to the position of the screw hole and then are directly connected.

When the dismounting device is used for dismounting, the movable sleeve 3.2 on the lower connector 3 is moved upwards, so that the dismounting sleeve 3.7 moves upwards along with the movable sleeve 3.2, the dismounting sleeve 3.7 separates the inclined plastic column 3.5 from the inner wall of the upper connector head 2.1 of the blanking pipe to be replaced below, the friction force received by the upper connector head 2.1 is reduced, and the blanking pipe to be replaced below can be easily dismounted.

The blanking pipe body that mentions in this patent mainly indicates curve coal breakage pipe, and traditional coal conveying system coal breakage pipe and belt feeder head funnel design are standard component, do not consider the throwing material curve of material and its motion trail in the coal breakage intraduct, though can make the design simple and convenient, nevertheless have following some problems: the phenomena of serious field dust pollution and coal blockage at the transfer point occur sometimes, and the lining plate inside the coal dropping pipe is particularly seriously worn and needs to be frequently replaced. The curve coal dropping pipe technology controls the generation of dust from the source through dynamic analog simulation of coal flow and avoids the occurrence of coal blockage.

The upper connecting method disc and the lower connecting method disc used in the patent are flanges, the flanges are called flanges for short, and are only called as a whole, and usually, a plurality of fixing holes are formed in the periphery of a metal body similar to a disc to be used for connecting other objects.

The plastic column that uses in this patent is the cylinder of plastic material.

The steel wire rope is a spiral steel wire bundle formed by twisting steel wires with mechanical property and geometric dimension meeting requirements together according to a certain rule, and consists of the steel wires, a rope core and lubricating grease. The steel wire rope is a spiral rope which is formed by twisting a plurality of layers of steel wires into strands, and then twisting a certain number of strands by taking a rope core as a center. In a materials handling machine, for lifting, pulling, tensioning and carrying. The steel wire rope has high strength, light dead weight, stable work, difficult sudden whole breakage and reliable work. This patent is ordinary wire rope, plays to draw the purpose of rising.

The removal sleeve and the traveling sleeve described in this patent are both sleeves, and the traveling sleeve can move up and down, but the removal sleeve supports upward movement, and when moving down, can be blocked by the inclined plastic column, just like the principle of a plastic expansion bolt.

The foregoing description is only exemplary of the preferred embodiments of the invention and is illustrative of the principles and techniques that may be employed. Meanwhile, the scope of the invention according to the present application is not limited to the technical solutions in which the above-described technical features are combined in a specific manner, and also covers other technical solutions in which the above-described technical features or their equivalent are combined arbitrarily without departing from the inventive concept described above. For example, the above features may be replaced with (but not limited to) features having similar functions disclosed in the present application.
