Abstract
A kind of impact-resistant abrasion-proof lining board is applicable to that industry materials such as mine, harbour, cement and iron and steel transport the lining of magazines, hopper, chute.Comprise: the polyurethane plate body, the top layer heat cure of polyurethane plate body has a plurality of alumina balls; The bottom of polyurethane plate body is connected with steel plate by reinforcing network, reinforcing network fixedly connected with steel plate and the reinforcing network heat cure in the polyurethane plate body; Steel plate is provided with back of the body nail hole, and back of the body nail fills the polyurethane that has with polyurethane plate body one in the hole.Liner plate is provided with nut hole for sleeping in and bolt preformed hole.The periphery of steel plate is provided with polyurethane and coats.Polyurethane plate body and steel plate are connected firmly among the present invention, and more shock resistance is more wear-resisting.
Description
Technical field
The present invention relates to a kind of abrasion-proof backing block, relate in particular to a kind of impact-resistant abrasion-proof lining board.
Background technology
Abrasion-proof backing block is the lining that is widely used in industry material transportation magazines such as mine, harbour, cement and iron and steel, hopper, chute, reaches the impact-resistant abrasion-proof effect, and magazine is not damaged.The prior art abrasion-proof backing block be with the polyurethane heat cure in steel plate, make full use of the elasticity and the wearability of polyurethane, reach wear-resisting purpose.But in use appear at the phenomenon that polyurethane and steel plate break away under the strong impact force effect, it is not enough to show impact resistance, polyurethane is also undesirable to sharper material shock resistance, steel plate is insecure with being connected of polyurethane, in order to overcome these 2 deficiencies of abrasion-proof backing block, invented impact-resistant abrasion-proof lining board.
Summary of the invention
The objective of the invention is to solve the polyurethane plate body and be connected insecure this problem with steel plate, and increased impact resistance and wearability, promptly the invention provides a kind of impact-resistant abrasion-proof lining board.
For achieving the above object, the technical solution used in the present invention is:
A kind of impact-resistant abrasion-proof lining board comprises: the polyurethane plate body is characterized in that: the top layer heat cure of polyurethane plate body has a plurality of alumina balls; The bottom of polyurethane plate body is connected with steel plate by reinforcing network, reinforcing network fixedly connected with steel plate and the reinforcing network heat cure in the polyurethane plate body; Steel plate is provided with back of the body nail hole, and back of the body nail fills the polyurethane that has with polyurethane plate body one in the hole.
According to described impact-resistant abrasion-proof lining board, it is characterized in that: described impact-resistant abrasion-proof lining board is provided with nut hole for sleeping in and bolt preformed hole.
According to described impact-resistant abrasion-proof lining board, it is characterized in that: the periphery of described steel plate is provided with polyurethane and coats.
According to described impact-resistant abrasion-proof lining board, it is characterized in that: the diameter of described alumina balls is 1～20mm, and alumina balls can be same kind of diameter ball, also can be the mixing ball of different-diameter.
Polyurethane plate body and steel plate are connected firmly among the present invention, and in the heat cure of polyurethane sheet body surface layer wear-resisting alumina balls are arranged, and more shock resistance is more wear-resisting than original product.The present invention tests in cement plant and colliery, and the result shows that wearability is about 4 times of steel plate.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the vertical view of Fig. 1.
In the accompanying drawing: 1, nut hole for sleeping in; 2, alumina balls; 3, polyurethane plate body; 4, reinforcing network; 5, back of the body nail hole; 6, steel plate; 7, bolt preformed hole; 8, polyurethane coats.
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments:
The present invention comprises as shown in Figure 1: polyurethane plate body 3, the top layer heat cure of polyurethane plate body 3 has a plurality of alumina balls 2.The bottom of polyurethane plate body 3 is connected with steel plate 6 by reinforcing network 4, and reinforcing network 4 can adopt steel mesh, and reinforcing network 4 is fixedlyed connected with steel plate 6 spot welding.Reinforcing network 4 heat cures are in polyurethane plate body 3.
Impact-resistant abrasion-proof lining board is provided with nut hole 1 for sleeping in and bolt preformed hole 7.
The periphery of steel plate 6 is provided with polyurethane and coats 8.
Design principle of the present invention: impact-resistant abrasion-proof lining board adopts polyurethane and the firm connection method of steel plate, and polyurethane skin layer is used alumina balls.
The firm connection method of polyurethane and steel plate mainly contains 2 points, and the one, steel plate increases back of the body nail hole, and full back of the body nail hole does not break away from steel plate and polyurethane before polyurethane is uncured; The 2nd, steel plate spot welding steel mesh, after the cleaning, the steel mesh heat cure is in polyurethane.
A plurality of alumina balls are used on the top layer of polyurethane plate body.The alumina balls that use are alundum (Al balls, are the high abrasion objects, and its heat cure in polyurethane skin layer, is strengthened anti-wear performance.The size of alumina balls is impacted according to the scene and the degree of friction is determined, the alumina balls diameter in the scope of φ 1～50mm, preferred 1～20mm.
A plurality of alumina balls can be as required with a kind of diameter ball (as φ 10mm), also can adopt the sizes of balls of different-diameter to mix (as φ 10mm, φ 2mm).
Sizes of balls is mixed the top layer of filled polyurethane plate body, and big ball is at big material, and is little of little material, helps the slit that reduces wear, and increases liner plate service life.
