Description

Technical Field

[0001] The utility model relates to the field of wear-resistant lining plates, in particular to a novel connection and installation structure of a composite wear-resistant lining plate. Background Art

[0002] Composite wear-resistant linings are widely used in power plants, docks, and mines. They are mainly used in material pipelines, hoppers, silos and other parts. They are very important for the safe production and economic benefits of enterprises.

[0003] There are three main ways to install and connect wear-resistant linings:

[0004] 1. Cut into different sizes and directly weld them to the steel plates of pipelines and silos. The disadvantages of this connection method are that it is difficult to replace, labor-intensive and time-consuming. When the wear-resistant lining is worn to a certain extent, the remaining part needs to be cut off, which is inconvenient to operate, has a low safety factor, is time-consuming and costly.

[0005] 2. Welding and stud connection on the lining. This welding method is difficult to achieve consistency in size with the hole size of the silo, resulting in a 0.5-1mm deviation in the installation size. It cannot be installed and the hole needs to be re-drilled, which has high labor costs. More importantly, since the studs are welded on, if there is a stud, the welder may accidentally cause insufficient welding or false welding. During use, since the belt conveyor is used to transport materials under the silo, the lining is likely to cause the belt to tear, which often leads to major safety accidents;

[0006] 3. Dig countersunk holes (conical circular holes) on the lining. Since the surface of the wear-resistant layer of the wear-resistant lining is extremely hard, ordinary alloy drills cannot drill holes at all. Using imported tungsten carbide alloy drills to drill holes costs about 6-7 yuan per hole, and drilling a hole takes a long time, resulting in increased costs. The existing wear-resistant lining connection method is inconvenient to operate, has a low safety factor, is time-consuming, and has a high cost, and is less practical.

[0007] Therefore, it is necessary to provide a new type of connection and installation structure of a composite wear-resistant liner to solve the above technical problems. Utility Model Content

[0008] The utility model provides a novel connection and installation structure of a composite wear-resistant lining plate, which solves the problems of inconvenient operation, low safety factor, long time consumption, high cost and poor practicality of the wear-resistant lining plate connection method.

[0009] In order to solve the above technical problems, the utility model provides a novel connection and installation structure of a composite wear-resistant liner, comprising: a wear-resistant liner body;

[0010] Mounting holes, four of which are opened around the surface of the wear-resistant lining plate, a bushing is arranged inside the mounting hole, and a countersunk stud is arranged in the middle of the bushing;

[0011] A welding layer is arranged on the rear side of the mounting hole.

[0012] Preferably, the mounting hole is in a truncated cone shape, with a larger diameter at the front side and a smaller diameter at the rear side.

[0013] Preferably, the bushing is in a frustoconical shape, with a larger diameter at the front side and a smaller diameter at the rear side.

[0014] Preferably, the bushing and the rear side of the mounting hole are connected in the welding layer by welding.

[0015] Preferably, a connecting groove is provided in the middle of one side of the wear-resistant lining plate body, and both sides of the connecting groove are connected with connecting holes.

[0016] Preferably, a bolt is disposed inside the communicating hole, and a nut is threadedly engaged on one side of the outer surface of the bolt.

[0017] Preferably, a connection block is fixedly installed in the middle of the other side of the wear-resistant lining plate body, and connection holes are opened on both sides of the surface of the connection block.

[0028] The utility model is further described below in conjunction with the accompanying drawings and implementation modes. Example

[0029] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A structural schematic diagram of a first embodiment of a novel connection and installation structure of a composite wear-resistant liner provided by the utility model; Figure 2 for Figure 1 The schematic diagram of the wear-resistant lining plate structure shown; Figure 3 for Figure 1 Schematic diagram of bushing structure shown; Figure 4 for Figure 1 A new type of connection and installation structure of a composite wear-resistant liner includes: a wear-resistant liner body 1;

[0030] Mounting holes 2, four of which are provided around the surface of the wear-resistant lining plate body 1, a bushing 3 is provided inside the mounting hole 2, and a countersunk stud 4 is provided in the middle of the bushing 3;

[0031] The welding layer 5 is arranged at the rear side of the mounting hole 2 .

[0032] The mounting hole 2 is in a truncated cone shape, with a larger diameter at the front side and a smaller diameter at the rear side.

[0033] The bushing 3 is in a truncated cone shape, with a larger diameter at the front side and a smaller diameter at the rear side.

[0034] The bushing 3 and the rear side of the mounting hole 2 are connected in the welding layer 5 by welding.

[0035] The working principle of a new type of connection and installation structure of a composite wear-resistant lining provided by the utility model is as follows:

[0036] During operation, first, when the liner is plasma cut, the mounting holes 2 are directly opened on the wear-resistant liner body 1. Each liner basically has 4 holes. Due to the plasma cutting, the upper hole and the lower hole form a deviation, the upper hole is large, and the lower hole is small. For example, for an 8+8mm wear-resistant liner body 1, the upper hole is 38mm and the lower hole is 36mm.

[0037] The bushing 3 is made of 45# steel and connected with M16 bolts, for example.

[0038] This type of bushing is processed outsourced and costs 2.7 yuan per piece.

[0039] Use a press to press the bushing 3 directly into the mounting hole 2 of the wear-resistant lining body 1. Since the upper opening of the mounting hole 2 is large and the lower opening is small, and the bushing 3 is a straight column, it is very firm after being pressed down. The back side of the bushing 3 is welded so that the rear side of the bushing 3 and the mounting hole 2 are welded together.

[0040] When installing this bushing 3, use M16 countersunk studs to install it. Since the inner hole diameter is Φ18 and the countersunk hole diameter is Φ16, there is room for adjustment in the four holes.

[0041] After wear, it is easy to replace.

[0042] Compared with the related art, the novel connection and installation structure of the composite wear-resistant lining provided by the utility model has the following beneficial effects:

[0043] The utility model provides a novel connection and installation structure of a composite wear-resistant lining plate, through the cooperation of a wear-resistant lining plate body 1, a mounting hole 2, a bushing 3, a countersunk stud 4 and a welding layer 5, the operation mode of the wear-resistant lining plate body 1 is convenient and simple, the safety factor is high, the time consumption is short and the cost is low.

[0047] A connection block 10 is fixedly installed in the middle of the other side of the wear-resistant lining plate body 1 , and connection holes 11 are opened on both sides of the surface of the connection block 10 .

[0048] When the connecting blocks 10 and the connecting grooves 6 of the two wear-resistant lining plate bodies 1 are spliced ​​together, the connecting holes 11 and the communicating holes 7 are communicated with each other.

[0049] The working principle of a new type of connection and installation structure of a composite wear-resistant lining provided by the utility model is as follows:

[0050] During operation, firstly, insert the connecting block 10 of one wear-resistant lining plate body 1 into the connecting groove 6 of another wear-resistant lining plate body 1, so that the connecting hole 7 and the connecting hole 11 are connected to each other, and the user inserts the bolt 8 into the connecting hole 7 and the connecting hole 11, and the rear end of the bolt 8 extends to the rear side of the wear-resistant lining plate body 1, and the user engages the nut 9 with the rear side of the outer surface of the bolt 8, so that the nut 9 is engaged with the thread and fits on the surface of the wear-resistant lining plate body 1 to prevent the bolt 8 from detaching.
