Description
Technical Field
The utility model relates to a wear-resisting for welt steel technical field, concretely relates to wear-resisting welt.
Background
The autogenous mill is an ore grinding device with two functions of crushing and grinding, and the material to be ground is used as a medium to realize crushing through mutual impact and grinding. The autogenous mill can cause the wearing and tearing of its inner wall welt in impact and grinding process to reduce the life of welt. But because the wear resistance and the impact resistance of the lining plate are poor, the service life is short, and the replacement cost is high. The reason for the short service life of the lining plate is that the structure of the lining plate is unreasonable, which is an important factor except that the wear resistance of the material is not enough. In addition, the later maintenance and replacement of the existing lining plate are also inconvenient.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to prior art not enough, provide a wear-resisting welt of reliable performance, can improve the wearability and the obdurability of welt by a wide margin, prolong its life, and easily change.
The technical scheme of the utility model is realized like this: a wear-resistant lining plate is characterized in that: the base plate comprises a base plate in a ship-shaped structure, a reinforcing rib plate is obliquely arranged at one end of the base plate, a first wear-resistant boss and a second wear-resistant boss are respectively arranged on the base plate in an arc shape, a wear-resistant groove is formed between the first wear-resistant boss and the second wear-resistant boss, a first mounting counter bore is formed in the first wear-resistant boss, and a second mounting counter bore is formed in the second wear-resistant boss.
Preferably, first installation counter bore and second installation counter bore all include nut mounting hole and bolt mounting hole, be equipped with the circumference chamfer on the lateral wall between nut mounting hole and the bolt mounting hole.
The thickness of the base plate is 8-20 mm, and a plurality of long-strip-shaped waist holes are formed in the wear-resistant grooves.
Preferably, the inclination angle α between the reinforcing rib and the base plate is 30 to 42 °.
And hoisting holes for hoisting are formed in the side walls of the first wear-resistant boss and the second wear-resistant boss.
The wear-resistant lining plate is cast by a high-manganese steel material with high toughness.
The utility model provides an existing defect among the background art, have following beneficial effect:
a wear-resisting welt, can improve the wearability and the obdurability of welt by a wide margin, prolong its life, and easily change. The self-grinding machine is installed in the first and second installation counter bores through bolts and nuts, so that the ore cannot hit the bolt head exposed outside the lining plate due to abrasion, the lining plate cannot fall into a crushing cavity after falling off to damage the crusher, the occurrence of damage accidents of the self-grinding machine in the process of crushing materials is prevented, and the actual starting rate of the self-grinding machine is improved. The arc-shaped first and second wear-resistant bosses arranged on the base plate not only improve the anti-impact capability of the lining plate, but also enable ore particles sliding downwards along the inner wall of the machine to slide more easily, and improve the working efficiency of the machine. The arrangement of the reinforcing rib plate improves the overall strength and the wear resistance of the wear-resistant lining plate. When later maintenance is changed, only the first and second mounting counter bores are needed to realize, so that the device is convenient and fast.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive exercise.
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a front view of FIG. 1;
in the figure: the method comprises the following steps of 1-a base plate, 2-a reinforcing rib plate, 3-a first wear-resistant boss, 4-a second wear-resistant boss, 5-a wear-resistant groove, 6-a first mounting counter bore, 7-a second mounting counter bore, 8-a hoisting hole, 61-a nut mounting hole and 62-a bolt mounting hole.
Detailed Description
Examples
As shown in fig. 1 and 2, the base plate comprises a base plate 1 in a boat-shaped structure, a reinforcing rib plate 2 is obliquely arranged at one end of the base plate 1, a first wear-resistant boss 3 and a second wear-resistant boss 4 in arc shapes are respectively arranged at the upper part of the base plate, a wear-resistant groove 5 is arranged between the first wear-resistant boss 3 and the second wear-resistant boss 4, a first mounting counter bore 6 is arranged on the first wear-resistant boss 3, and a second mounting counter bore 7 is arranged on the second wear-resistant boss 4. The first mounting counter bore 6 and the second mounting counter bore 7 both comprise a nut mounting hole 61 and a bolt mounting hole 62, and a circumferential chamfer is arranged on the side wall between the nut mounting hole 61 and the bolt mounting hole 62. The thickness of the base plate 1 is 8-20 mm, and a plurality of long-strip-shaped waist holes are formed in the wear-resistant grooves 5. The inclination angle alpha between the reinforcing rib 2 and the base plate 1 is 30-42 deg. Hoisting holes 8 are formed in the side walls of the first wear-resistant boss 3 and the second wear-resistant boss 4. The wear-resistant lining plate is cast by a high-toughness high manganese steel material. The thickness of the base plate 1 is 8-20 mm, conventional steel plates on the market meet requirements, and the applicability is stronger.
The utility model discloses a working process is: the fixing bolt M20 passes through the first mounting counter bore 6 and the second mounting counter bore 7 from the back side, and the front side is fixed by the nut M20, so that the wear-resistant lining plate is mounted on the inner wall of the autogenous mill. The number of the wear-resistant lining plate main bodies can be specifically determined according to the area of the inner wall of the autogenous mill. In the process of machine crushing ore, compare with traditional structure, because bolt and nut are installed in first, two installation counter bores 6, 7, consequently the ore can not hit the bolt head that the wearing and tearing expose at the welt outside, causes the welt to fall into broken intracavity after dropping off and damages the breaker, prevents the emergence of the in-process damage accident of autogenous mill at broken material, improves the actual start-up rate of autogenous mill. The arc-shaped first and second wear- resistant bosses 3 and 4 arranged on the base plate 1 not only improve the anti-impact capability of the lining plate, but also enable ore particles sliding downwards along the inner wall of the machine to slide more easily, and improve the working efficiency of the machine. The arrangement of the reinforcing rib plate 2 improves the overall strength and the wear resistance of the wear-resistant lining plate. When later maintenance is changed, only the first and second mounting counter bores 6 and 7 are needed to be used, so that convenience and rapidness are achieved. Be provided with hole for hoist 8 on first wear-resisting boss 3 and the wear-resisting boss 4 lateral wall of second, the installation of lifting by crane of the antifriction plate of being convenient for improves the installation effectiveness of autogenous mill.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
