Abstract
The utility model discloses an abrasion-proof device of a fixed bolt, and the abrasion-proof device comprises an abrasion-proof member main body, and the abrasion-proof member main body is a backing drum which is formed by welding a steel pipe and a flat gasket. When the fixed bolt is connected with a nut, the backing drum is sleeved between the bolt and the nut, so that the ore pulp can be prevented from washing the front surface of the nut, and the fixed bolt and the bolt are durable.
Description
Technical field
The utility model relates to a kind of shoe, relates in particular to a kind of shoe of fixing bolt.
Background technique
At present, nut and bolt are the fastening pieces of commonly using.In mining machinery, frequency of utilization is very high.
In the flotation cell of mineral smelting, ore pulp can constantly wash away the nut in the flotation cell from the side, causes the wearing and tearing of nut, thereby has increased the frequency of maintenance, the loss that has strengthened material.
Up to now, the fine technological scheme that solves the problems of the technologies described above does not also appear on the market.
The model utility content
The purpose of this utility model provides a kind of fixing bolt shoe, can reduce frequency of maintenance, reduces spillage of material.
The utility model adopts following technical proposals: a kind of fixing bolt shoe, comprise abrasionproof spare main body, and abrasionproof spare main body is the pad cylinder that the bottom surface has the through hole that penetrates for bolt.The pad cylinder of described pad cylinder for being welded by steel pipe and flat gasket.
The utility model can avoid ore pulp to directly the washing away of nut because the pad cylinder that has the abrasionproof function in the outer installment of fixing bolt is applied in the flotation cell of mineral smelting, thereby prolongs the working life of nut.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model provides a kind of fixing bolt shoe, comprises abrasionproof spare main body, and abrasionproof spare main body is the pad cylinder that steel pipe 3 and flat gasket 4 are welded.
When bolt 1 engages with nut 2, at middle cover pad cylinder, thereby avoided ore pulp that the front of nut 2 is washed away, make fixing bolt 1 and nut 2 durables.
Those skilled in the art can expect that the pad cylinder also can directly be cast and form.
Claims (2)
1. fixing bolt shoe is characterized in that: comprise abrasionproof spare main body, abrasionproof spare main body is the pad cylinder that the bottom surface has the through hole that penetrates for bolt.
2. shoe according to claim 1 is characterized in that: the pad cylinder of described pad cylinder for being welded by steel pipe and flat gasket.
