Abstract
The uniform strength edge double-chain scraper of the utility model belongs to coal mine machinery fittings and is used for edge double-chain scraper conveyor with various models. The utility model, with the advantages of high strength, light weight, high strength and light weight, firstly arranges reasonable stressed state to an I-shaped cross section and then designs the scraper into an arc variable cross-section uniform strength structure. Tests indicate that the utility model is reasonably stressed.
Description
The utility model belongs to the coal mine machinery accessory.Mainly be used on the limit double chain conveyor of various models, work to scrape fortune coal.
Current, in the Coal Transport under the coal mine, be extensive use of limit double chain conveyor such as Britain's road ladder--ML-722 slat conveyer of Mai Ke company etc., scraper plate is the important accessory on it.
There is following shortcoming in currently used scraper plate, shown in Figure 1 as in the Figure of description: the structure of this type of scraper plate was: scraper plate was the strip I-shaped cross section structure of a uniform cross section, shown in the A-A cross section.For sake of convenience, we claim base plate with the top and the bottom of I-shaped cross-section, and centre portion claims gusset.On the gusset at scraper plate two ends, be drilled with the hole that chain is installed.
Because the strained condition of scraper plate belongs to single supported beam and is subjected to this type of uniform load, its mechanical characteristics is: the suffered stress maximum in scraper plate middle part, to two ends gradually.This has just caused the problem of following two aspects: the firstth, and it is big that prismatic strip structure is not suitable for the suffered stress in cross section, middle part, to two ends strained condition gradually, make the middle part undercapacity and fracture failure takes place, and the too high weight that makes of the intensity at two ends increases.Second because the hole of chain of being installed is arranged on the gusset, and it is vertical with gusset to load onto the chain rear chain, causes scraper plate to be subjected to force direction shown in A-A cross section arrow points among Fig. 1 when work.For the I-shaped cross-section, stressedly like this make section modulus less, can not give full play to the intensity of structure, therefore this type of scraper plate easy fracture lost efficacy at present, heaviness.
The purpose of this utility model is to provide a kind of stressed rational scraper plate rational in infrastructure, and to improve intensity, expendable weight reduces fracture failure.
Task of the present utility model realizes with the following methods: shown in Figure 2 as in the Figure of description: at first the cross section of this structure is a variable section structure, be a camber structure, be scraper plate middle part section modulus maximum, take second place to two ends, so the intensity at scraper plate middle part is the highest, take second place to two ends, such cross section just adapts with aforesaid scraper plate strained condition, and the intensity of structure is given full play to, and has alleviated weight.The gusset of second structure is a horizontal positioned, upper and lower bottom plate merges together at the two ends of scraper plate, and system of boring is installed the hole of chain on it, and chain is parallel with gusset like this, vertical with base plate, then just cause scraper plate be subjected to force direction shown in the arrow points in the B-B cross section.Strength of material calculates and shows, increases by 3 times to the I-shaped cross-section is stressed like this than aforesaid strained condition section modulus.The utility model just becomes a stressed rational equal strength structure like this.
Materials mechanics experimental shows: by single supported beam test condition is set, under equal test condition, the utility model scraper plate can make the more former scraper plate of bending strength increase two times, and weight saving 1/3rd, because the reasonableness of stressed and structure, the utility model has higher margin of strength, has reduced fracture failure.
Claims (3)
1, a kind of equal strength limit double chain conveyor scraper plate, it is characterized in that: whole scraper plate is an equal strength variable section structure.
2, by the described scraper plate of claim 1, it is characterized in that: cross section, scraper plate middle part is an I-shape, the maximum two ends of scraper plate midsection modulus gradually, whole scraper plate is an arc equal strength variable section structure.
3, by the described scraper plate of claim 1, it is characterized in that: the base plate of I-shaped cross-section merges together at the scraper plate two ends becomes a plate, and the system of boring is installed the hole of chain thereon.
