In the figure: the anti-abrasion device comprises a C-shaped groove 10 of the mining conveyor, a supporting base plate 100, an anti-abrasion bulge 101, a lubricating groove 102, an anti-deformation bulge 103, a C-shaped ledge 200 and an installation bulge 201.

Detailed Description

The following combines the drawings of the utility model to further elaborate the technical scheme and technical effect of the utility model.

Referring to fig. 1 to 3, in a specific embodiment, a C-shaped groove 10 of a mining conveyor is installed between two side walls of the mining conveyor, and includes a supporting base plate 100 and C-shaped walls 200 disposed on two sides of the supporting base plate 100, wherein installation protrusions 201 are disposed on outer sides of two ends of the C-shaped walls 200, and the installation protrusions 201 can be installed in contact with inner walls of the walls. For example, the installation protrusions 201 extend inward from both ends of the C-shaped ledge 200 by 10cm to 40cm, that is, the length of the installation protrusions 201 is 10cm to 40cm, and is preferably equal to the height of the C-shaped ledge 200. The thickness of the mounting protrusion 201 is 3mm to 10mm, preferably 5 mm.

During installation, the installation is only carried out through the installation bulges 201 and the two side walls of the middle groove of the mining conveyor, and the middle part of the C-shaped ledge 200 is not required to be contacted with the two side walls of the middle groove. Therefore, when the C-shaped groove 10 of the mining conveyor is processed, only the installation bulge 201 needs to be polished and finished, and the whole side surface of the C-shaped ledge 200 does not need to be finished, so that the processing difficulty is reduced, and the processing workload is reduced.

Referring to fig. 3, in a preferred embodiment, anti-wear protrusions 101 are arranged on the upper surface of the supporting base plate 100 side by side along the length direction of the supporting base plate 100, and a lubrication groove 102 is formed between two adjacent anti-wear protrusions 101.

On the one hand, increased in a similar manner the thickness at the easy wearing and tearing position of supporting baseplate 100 both sides prolongs the life in C type groove, and on the other hand, the buggy falls into adjacent two in the lubrication groove 102 between the abrasionproof decreases arch 101, with scrape the in-process of scraper chain collision contact friction, the buggy can play the effect of emollient, has reduced supporting baseplate's abrasion strength by a wide margin. In another aspect, the anti-wear protrusions 101 are equivalent to reinforcing ribs disposed on the supporting base plate 100, so that the physical strength of the supporting base plate 100 is enhanced, and the deformation rate of the supporting base plate is suppressed.

Specifically, the raised 101 of abrasionproof decreases is close to C type ledge 200 sets up, the total width of the raised 101 of abrasionproof decreases is 15cm ~ 30cm, that is to say supporting baseplate 100 is close to the both sides of C type ledge 200 set up the protruding 101 of abrasionproof decreases, and is a plurality of the protruding width that forms of abrasionproof decreases region for 15cm ~ 30cm, preferably, the abrasionproof decreases regional can cover scrape the chain with supporting baseplate's contact friction region.

Further, the abrasion prevention protrusions 101 are corrugated, for example, the abrasion prevention protrusions 101 are in a positive corrugation shape, wherein the amplitude of the positive corrugation is 5mm to 20mm, and the wavelength is 10mm to 30 mm. When the wave crest of the anti-abrasion bulge 101 contacts with the scraper chain, the contact area is reduced, the abrasion thickness is increased, and the abrasion of the supporting bottom plate 100 is effectively slowed down. At the trough position, the coal powder is filled to play a role in lubrication, so that the abrasion of the scraper chain to the supporting bottom plate 100 is further reduced. In addition, the anti-abrasion protrusions 101 arranged in the shape of a sine wave are convenient to clean and inspect and maintain the equipment.

In another embodiment, the lower surface of the support base plate 100 is provided with deformation preventing protrusions 103, for example, the deformation preventing protrusions 103 are arranged in a corrugated shape. The deformation-preventing protrusions 103 are equivalent to reinforcing ribs arranged at the bottom of the supporting base plate 100, so that the strength of the supporting base plate 100 is effectively enhanced, the deformation speed of the supporting base plate 100 is delayed, and the service life of equipment is prolonged.

In another embodiment, the mining conveyor C-shaped groove 10 is integrally cast and formed by using a lost foam, so as to further enhance the mechanical strength of the mining conveyor C-shaped groove 10 and eliminate the risk of weld cracking caused by abrasion of the supporting bottom plate 100.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
