Problems solved by technology
[0003] Most of the middle tanks of the existing scraper conveyors are not equipped with wear-resistant layers, resulting in a short service life of the equipment. Since the middle tanks are mostly fixed under the mine, the equipment is bulky and inconvenient to replace, which greatly affects the continuity of production and Difficulty in construction; even if there is a middle groove of the conveyor equipped with a wear-resistant layer, the design of the wear-resistant layer is unreasonable, which affects the normal operation of the equipment. At the same time, the wear-resistant effect is not good, and a good wear-resistant effect cannot be achieved

Embodiment Construction
[0042] Such as figure 1 , figure 2 and image 3 The shown scraper conveyor with a wear-resistant layer is a mature prior art, including a bottom plate 4, a middle plate 2 and an E-shaped groove side 5. On the basis of the prior art, the present application sets the wear-resistant layer 1 on the bottom plate 4, the middle plate 2 and the E-shaped groove side 5, and enhances the wear resistance of the scraper conveyor by setting the wear-resistant layer 1, so that the scraper Conveyors are more suitable for coal mine transportation.
[0043] Wherein, the setting position of wear-resistant layer 1 is the upper surface of base plate 4, middle plate 2 and E-shaped groove side 5; the thickness of wear-resistant layer 1 is 3-5mm, preferably 4mm, and the wear-resistant layer of this thickness is on the one hand The wear resistance of the bottom plate 4, the middle plate 2 and the E-shaped groove side 5 is enhanced, and on the other hand, the normal operation of the bottom plate 4,...

Abstract
The invention discloses a melting compound process for abrasion-resistant layers of a scraper plate conveyor and the scraper plate conveyor with the abrasion-resistant layers. The scraper plate conveyor comprises a bottom plate, a middle plate and an E-shaped ledge. The bottom plate, the middle plate and the E-shaped ledge are all provided with the abrasion-resistant layers. The melting compound process for the abrasion-resistant layers comprises the steps that firstly, the middle plate is horizontally arranged on the upper face, and the upper surface of the middle plate is pressed by a pressing plate and faces upwards; secondly, welding machine parameters are adjusted; and finally, surfacing is conducted, specifically, the welding machine runs in the width direction of the middle plate and then runs in the length direction of the middle plate, and a continuous melt plated band is formed through sequential cycles. The middle plate, the bottom plate and the E-shaped ledge of the scraper plate conveyor are provided with the abrasion-resistant layers, so that the abrasion resistance of the scraper plate conveyor is improved. Meanwhile, through melting compound of the abrasion-resistant layers, the abrasion-resistant layers subjected to melting compound is even in thickness, low in cost and good in application effect.
Description
technical field [0001] The invention belongs to the field of scraper conveyors, and in particular relates to a melting and compounding process of a wear-resistant layer of a scraper conveyor and a scraper conveyor with a wear-resistant layer. Background technique [0002] In coal mine production, the scraper conveyor is used in conjunction with shearer, hydraulic support and other equipment to transport the coal mined in the fully mechanized mining face to subsequent equipment. The traction mechanism of the scraper conveyor is the scraper chain, the carrying device is the middle trough, and the scraper chain is installed on the surface of the middle trough. The central trough is fully laid along the transportation route, and is matched with the roller shearer and the conveyor moving device to realize the mechanization of coal dropping, coal loading, coal transportation and moving transportation. The middle trough of the scraper conveyor is subject to various effects such as...
