Abstract

The utility model relates to a batter board hook for protecting a copper lining tile, which is used for large cranes in metallurgy. Because of higher working frequency, large loading, high temperature working environment, much dust and the difficulty of the surface lubrication of the copper lining tile, the copper lining tile frequently works in the state of dry friction to cause that the abrasion is serious and the service life is short. The utility model adopts the measures that the line is scribed and the hole is drilled on the sliding surface of the copper lining tile, and the solid self-lubrication stick is adhered into integration with nylon 16 adhesive; the self-lubrication layer which is formed on the surface of the copper lining tile reaches the purposes of reducing the abrasion of the copper lining tile and increasing the service life of the copper lining tile. The solid self-lubrication stick of the utility model is made of graphite, tungsten sulphide, dibutyl ester, poly hydracid poly potassium aldehyde ester, polytetrafluoroethylene, etc., which are mixed and stirred and formed by pressing by a pressing machine.

Description

Copper liner bush of with self-lubricant material

The utility model relates to the protection copper lining tile of goliath gantry plate hook gib head.

Occasion at goliath; when gantry plate hook is applied to handling steel ladle or ladle; removable protection copper lining tile (shown in figure one) is housed on the plate hook gib head; because operating rate height, load are big, and high temperature, many dirt, environment are abominable, add lining tile surface lubrication difficulty; therefore; in smelter, protection copper lining tile is easy to wearing and tearing on gantry plate hook of goliath, and generally only be about 3 months service life.

The utility model is to be used in and to embed solid self lubricant material on the copper lining tile to improve the service life of copper lining tile.

The utility model is to embed solid self lubricant material on the protection copper lining tile of gantry of goliath plate hook gib head.Its concrete grammar is: with the body of copper lining tile as matrix, on the sliding surface of copper lining tile, rule, hole, to by certain proportioning, granularity, evenly stir by various composition materials then, be pressed into the garden cylindricality lubricating rod of certain size again with compression machine, with the boring that lubricating rod is put into lining tile, adopt nylon 16 adhesive agents, be bonded to one, through natural seasoning in 24 hours it is solidified, formation has the copper lining tile (seeing for details shown in Figure 2) of inlaying solid self lubricant material.

Self-lubricating material is to be mixed by 40% graphite, 35% tungsten sulfide, 5% dibutylester, 5% dusting (the poly-potassium aldehydo-ester of poly-hydracid), 15% polytetrafluoroethylene, its mechanical characteristics is as shown in table 1, because embed solid self lubricant material, it forms certain topped area on the sliding surface of copper lining tile.

When the brass bricklayer is done, form one deck solid lubrication dielectric layer on the friction face, and constantly ooze out, form the good self-lubricating layer of one deck, reach desirable self-lubricating state, reduced the wearing and tearing of copper lining tile, improved 7--8 times of service life, lining tile abrasion loss relatively was shown in Table 2 before and after it improved.The self-lubricating material mosaic area accounts for the matrix sliding surface gross area 25～35%.

3 ┄ ┄ gantry plate hooks, 4 ┄ ┄ copper lining tiles,

Fig. 2, inlay the copper lining tile of solid self lubricant material: 5 ┄ ┄ solid self lubricant materials, 6 ┄ ┄ copper lining tiles,

Embodiment:

On the protection copper lining tile of gantry of large-scale metallurgical hoisting crane more than 100 tons plate hook gib head, adopt the method for inlaying solid self lubricant material.The copper lining tile adopts ferro-aluminum nickel bronze or ferro-aluminum manganese bronze, poured into centrifugal.Lining tile external diameter ∮ 1000mm, internal diameter ∮ 850mm, width 285mm inlaid hole gross area on the sliding surface of copper lining tile accounts for total lining tile slidingsurface long-pending 28%, inlay the gross thickness 75mm of degree of depth 40mm(copper lining tile), the self-lubricating material garden column diameter of inlaying is ∮ 25mm, inlay 193 on each copper lining tile, adopt arranged crosswise, make all inlaid holes no matter axially or radially, should all tangential overlapping be arranged, guarantee that whole friction face is evenly lubricated with adjacent holes, solid self lubricant material 40% graphite of inlaying on the copper lining tile in addition, 35% tungsten sulfide, 5% dibutylester, 5% dusting (the poly-potassium aldehydo-ester of poly-hydracid), 15% polytetrafluoroethylene mixes stirring, be pressed into ∮ 25mm lubricating rod with compression machine again,, adopt nylon 16 adhesive agents the boring that lubricating rod is put into the copper lining tile, stick into one, through natural seasoning in 24 hours, make its curing, promptly become and inlay shape copper lining tile.

Behind the copper lining tile of inlaying solid self lubricant material, average month abrasion loss is reduced to 1.3mm by 10.7mm, makes the copper lining tile extend to 2 years by 3 months service life.

Claims

1, inlay gantry plate hook gib head copper lining tile of solid self lubricant material, it is characterized in that, be drilled with several holes at copper lining tile inside face, be bonded with the self-lubricating solid rod in the hole, what form as one inlays solid self lubricant material copper lining tile.

2, gantry plate hook gib head copper lining tile of inlaying solid self lubricant material according to claim 1 is characterized in that the topped area of inlaying solid self lubricant material should account for 25～35% of copper lining tile inside face.
