Problems solved by technology

The failure form of the scraper conveyor is mainly manifested as wear failure. The middle plate of the scraper conveyor is the most serious part of the scraper conveyor wear part. At present, the common practice is to clad the diamond-shaped texture on the middle plate. The diamond-shaped design Fixed distribution, angle, size and other parameters have been used. When cladding the rhombus texture, there are many cladding connection points between the rhombus, which are called "lap points". resistance, increasing energy consumption; in addition, the vicinity of the central axis of the middle plate, the parts opposite to the raised part of the scraper, and the parts opposite to the chain are prone to wear and failure. Protect
[0003] The bottom plate of the scraper machine is also in direct contact with the chain and the scraper, and rubs repeatedly during work, which is similar to the wear and failure part of the middle plate; the wear and failure of the channel side steel is mainly caused by the wear of the inner surface of the scraper and the channel side steel , there is no effective protection for its worn parts

Embodiment 1

[0047] Such as figure 1 As shown, a scraper machine with a cladding texture includes a middle plate, a bottom plate and a channel side steel. The middle plate is clad with a straight line uniform texture higher than the middle plate, and the straight line uniform The texture is composed of straight wear-resistant strips 1, the height of the straight wear-resistant strips 1 is 1.5mm, the width is 9mm, and the distance between the centerlines of adjacent straight wear-resistant strips 1 is 10-50mm. The straight line uniform texture structure of this embodiment is simple, there is no overlapping point at all, and the running resistance of coal flow is reduced. The contact and wear with the medium plate substrate does not require full cladding, which reduces the cost.

Embodiment 2

[0049] Such as figure 2 As shown, a scraper machine with a cladding texture includes a middle plate, a bottom plate and a channel side steel, and the middle plate is clad with a linear distribution texture and a wear-resistant block 2 higher than the middle plate, so The linear distribution texture is composed of linear wear strips 1. The height of the linear wear strips 1 is 1.6mm and the width is 8mm. The distance between the centerlines of the straight wear-resistant strips 1 is 18mm, and the maximum distance between the straight-line wear-resistant strips 1 between adjacent groups is 60mm. When the scraper machine is working, the two raised parts on the lower surface of the scraper continuously rub against the middle plate, forming failure marks on the surface of the middle plate, which eventually causes the middle plate to fail. The position of the two sets of linear wear-resistant strips 1 on the outside of this embodiment is opposite to the raised part of the scraper,...

Embodiment 3

[0051] Such as image 3 As shown, a scraper machine with a cladding texture, the same part as the second embodiment will not be repeated, the difference is: this embodiment is a linear intermittent texture, the linear wear-resistant strip 1 is intermittent, the same The discontinuous positions of the linear wear strips 1 of the groups are the same, and the discontinuous positions of the linear wear strips of adjacent groups are different. In addition to the effect of the second embodiment, the linear intermittent texture of this embodiment also has the effect of reducing the deformation of the middle plate after cladding.

Abstract

The invention discloses a scraper conveyor and a loader with fusion covering textures. The scraper conveyor and the loader respectively comprise a middle plate, a bottom plate and channel steel, wherein at least one of the middle plates, the bottom plates and the channel steels is covered with a texture in a fusion way; each texture consists of at least one of a straight wearing strip, a diamond-shaped wearing strip, a curved-shaped wearing strip, a splay-shaped wearing strip, and a V-shaped wearing strip; the height of each texture is 1.5 to 2.5mm. The scraper conveyor and the loader with the fusion covering textures have the advantages that the abrasion-prone parts of the middle plates, the bottom plates and the channel steels of each part of the scraper conveyor and the loader are critically protected by the fusion covering textures, the service lives of the scraper conveyor and the loader are prolonged, the number of overlapping points is reduced, and the energy consumption is decreased.

Description

technical field [0001] The invention relates to the technical field of coal transportation machinery, in particular to a scraper machine and a transfer machine with a cladding texture. Background technique [0002] Scraper conveyor, also known as "scraper conveyor", is an important coal transportation equipment in coal mining operations at home and abroad. The failure form of the scraper conveyor is mainly manifested as wear failure. The middle plate of the scraper conveyor is the most serious part of the scraper conveyor wear part. At present, the common practice is to clad the diamond-shaped texture on the middle plate. The diamond-shaped design Fixed distribution, angle, size and other parameters have been used. When cladding the rhombus texture, there are many cladding connection points between the rhombus, which are called "lap points". resistance, increasing energy consumption; in addition, near the central axis of the middle plate, the parts opposite to the raised pa...
