Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

As shown in the attached drawings 1 to 4, a novel wear-resistant elbow device for conveying production mortar comprises an elbow main body 1, a connecting pipe 2 and a buffer mechanism. The elbow main body 1 comprises an input section 11, a bending section 12 and an output section 13 which are sequentially connected along the mortar conveying direction, and the elbow main body 1 is integrally bent by the bending section 12 to form a bent pipe with the input section 11 and the output section 13 forming a certain angle with each other.

As shown in fig. 1, the elbow main body 1 is provided with a through connection hole 14 on the back of the bending section 12, the connection hole 14 covers and fixes the buffer layer 4, and the buffer layer 4 may be an elastic rubber pad or a high density polyethylene plate. One end of the connecting pipe 2 is attached to the back of the bending section 12, and the buffer layer 4 is enclosed therein, the connecting pipe 2 and the bending section 12 may be directly fixed by welding, and the fixing manner not specifically described in this embodiment may be a welding process. The connecting pipe 2 is opposite to the other end of the elbow main body 1 and is detachably connected with an end cover 21, a flange plate is fixed at the tail end of the specific connecting pipe 2, a plurality of mounting holes are distributed on the same axis of the end cover 21 and the flange plate, after the mounting holes of the end cover 21 and the mounting holes of the flange plate are in one-to-one correspondence, the end cover 21 and the connecting pipe 2 can be fixedly connected by being locked and fixed with nuts after bolts are penetrated and installed, and when the end cover 21 needs to be detached, the bolts are detached.

Buffer gear is including roof 6, first baffle 5 and spring 7, roof 6 towards in one side of connecting hole 14 is equipped with the laminating the inclined plane of

buffer layer

4, 6 opposite sides of roof with first baffle 5 fixed connection, the other end of first baffle 5 is fixed with a plurality of spring 7, can make spring 7 all towards in end cover 21. The outer diameter of the first baffle 5 is slightly smaller than the pipe diameter of the connecting pipe 2, so that the first baffle 5 can only move along the length direction of the connecting pipe 2 after being embedded into the connecting pipe 2. As shown in fig. 4, during installation, after the whole buffering mechanism is embedded into the connecting pipe 2, the end cover 21 seals the port of the connecting pipe 2, so that the end cover 21 pushes the spring 7 toward the inside of the connecting pipe 2, and the spring 7 pushes the first baffle 5 and the top plate 6 to move toward the buffering layer 4, so that the top plate 6 presses the buffering layer 4 toward the inside of the bending section 12. After the mortar flows in from the input section 11 and is conveyed to the bending section 12 along the length direction of the input section 11, the mortar directly impacts the buffer layer 4 of the bending section 11, indirectly contacts the top plate 6 and is conveyed to the output section 13 under the guiding action of the inclined surface of the top plate 6. In the process, the mortar is conveyed to the buffer layer 4 to enable the buffer layer 4 to bulge towards the direction of the connecting pipe 2, the top plate 6 and the first baffle plate 5 are driven to move, the spring 7 between the first baffle plate 5 and the end cover 21 can play a role in buffering the pressure impact force of the mortar impacting the elbow main body 1, and the buffer layer 4 is prevented from being abraded greatly. In addition, the bending section 12 is internal corresponding to the lateral wall laminating of connecting hole 14 is fixed with wearing layer 10, and this wearing layer 10 equally can be the material of high density polyurethane board to this wearing layer 10's structure can prevent that the mortar from through the direction back of buffer layer 12 and roof 6, directly assaulting the lateral wall of bending section 12, thereby effectual improvement the utility model discloses wear-resisting elbow's life.

Preferably, as shown in fig. 5, the buffering mechanism may further include a second blocking plate 8, and the other end of each spring 7 connected to the first blocking plate 5 is fixedly connected to the second blocking plate 8. The gap between the second apron 8 and the end cap 21 is filled with resilient balls 9. The connecting pipe 2 is further connected with a leading-in pipe 3, one end of the leading-in pipe 3 is communicated into the connecting pipe 2, the other end of the leading-in pipe 3 is detachably connected with a sealing cover 31, and the leading-in pipe 3 and the sealing cover 31 are connected in the same way as the connecting pipe 2 and the end cover 21 and are connected through a flange plate, a bolt and a nut. When the device is installed, the buffer mechanism is embedded into the connecting pipe 2, and then the end cover 21 is fixed; and opening the sealing cover 31 again, filling the elastic ball 9 into the connecting pipe 2 from the inlet pipe 3 until the elastic ball 9 fills the connecting pipe 2 and the inlet pipe 3, and then fixing the sealing cover 31 on the pipe orifice of the inlet pipe 3, wherein the elastic ball 9 filled between the end cover 21 and the second baffle plate 8 can push the buffer mechanism into the connecting pipe 2, so that the top plate 6 presses the buffer layer 4 into the bending section 12.

When the utility model discloses wear-resisting elbow is fixed in when the vertical state as shown in figure 5, if the mouth of pipe of 21 one end of end cover through connecting pipe 2 packs elastic ball 9 in to connecting pipe 2, because connecting pipe 2 is in horizontal state, elastic ball 9 falls out from the mouth of pipe easily, is difficult to be filled up elastic ball 9 in connecting pipe 2. The elastic ball 9 is filled in the inlet pipe 2, so that the elastic ball 9 does not fall out of the connecting pipe 2, and the elastic ball 9 is more easily filled in the gap between the second baffle plate 8 and the end cover 21. After the mortar flows in from the input section 11 and is conveyed to the bending section 12 along the length direction of the input section 11, the mortar directly impacts the buffer layer 4 of the bending section 12, indirectly contacts the top plate 6 and is conveyed to the output section 13 under the guiding action of the inclined surface of the top plate 6. In this process, the mortar is carried to buffer layer 4 and is made buffer layer 4 bulge to 2 directions of connecting pipe to drive roof 6, first baffle 5 and second baffle 8 and remove, the spring that is located between first baffle 5 and the second baffle 8 this moment can play the effect of the pressure impact force that buffering mortar strikes elbow main part 1, prevents that buffer layer 4 from receiving great wearing and tearing greatly. In addition, at the initial stage of conveying the mortar, a large amount of mortar instantly flows into the input section 11, so that the instant pressure of the mortar input into the bending section 12 is large, the transverse pressure borne by the buffer layer 4 and the top plate 6 is large, the elastic ball 9 filled between the second baffle plate 8 and the end cover 21 can play a role of secondary buffer, and the rapid damage of the elbow caused by long-term use is further avoided.

The above-mentioned be the utility model discloses a concrete implementation way, nevertheless the utility model discloses a design concept is not limited to this, and the ordinary use of this design is right the utility model discloses carry out immaterial change, all should belong to the act of infringement the protection scope of the utility model.
