Description

Technical Field

[0001] This utility model relates to the field of vertical connecting chain links, specifically a super corrosion-resistant and ultra-strong mining vertical connecting chain link. Background Technology

[0002] In coal mining operations, scraper conveyors, transfer conveyors and other equipment undertake the key task of material transportation and are the core equipment to ensure efficient coal mining and transportation. As the core component of chain connection in these devices, the performance of mining chain links directly determines the stability, reliability and safety of the entire transportation system and plays a vital role in coal production efficiency and operational safety.

[0003] For example, CN220828479U discloses a highly stable vertical connecting link for mining chains, comprising a first half-ring and a second half-ring. A first ear plate is fixedly installed on the side of the first half-ring away from the hinge, and a second ear plate is fixedly installed on the side of the second half-ring away from the hinge. The same fastening bolt is installed through the first ear plate and the second ear plate, and a fastening nut for abutting the second ear plate is threaded onto the fastening bolt. A first protrusion is fixedly installed on the inner side wall of the first half-ring, and a screw is threadedly connected to the side wall of the second half-ring. A second protrusion is rotatably installed at one end of the screw, and a magnet for abutting the first protrusion is fixedly installed on the side end of the second protrusion. When the first and second half-rings are closed, the magnet attracts the first protrusion, thus initially fixing the first and second half-rings. Then, fastening bolts and nuts are installed sequentially, and tightening the nuts secures the first and second half-rings, improving post-installation stability. However, in existing devices, the vertical connecting chain links experience uneven stress distribution under complex and variable loads, leading to stress concentration in key areas. This causes premature fatigue cracks and subsequent fatigue fracture, resulting in chain disengagement and transport interruption. Furthermore, humid and corrosive environments accelerate metal corrosion, reducing material strength and toughness, further shortening the service life of the connecting chain links. Therefore, there is an urgent need to design a super-corrosion-resistant and ultra-strong mining vertical connecting chain link to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a super corrosion-resistant and ultra-strong vertical chain link for mining, in order to solve the problems mentioned in the background art. When the vertical chain link is subjected to complex and variable loads, the stress distribution is uneven, and stress concentration is prone to occur in some key parts, leading to premature fatigue cracks and fatigue fracture, which causes the chain to break and the transportation to be interrupted. At the same time, in humid and corrosive environments, the corrosion process of the metal is accelerated, reducing the strength and toughness of the material and further shortening the service life of the chain link.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a super corrosion-resistant and ultra-strong vertical connecting chain link for mining, comprising an upper connecting chain link body and a lower connecting chain link body, wherein the upper connecting chain link body and the lower connecting chain link body have the same structure and are mirror-connected, wherein the upper connecting chain link body and the lower connecting chain link body are threadedly fixed by a central bolt, and wherein both the upper connecting chain link body and the lower connecting chain link body are provided with a metal plating layer on their sides.

[0006] Preferably, the upper and lower connecting link bodies can be used individually, or they can be assembled into a group for use.

[0007] Preferably, a central ring groove is formed at the center of the upper connecting link body, a strip-shaped slot is formed at the front end of the upper connecting link body, and a strip-shaped protrusion is integrally cast on the bottom rear end of the upper connecting link body, the strip-shaped protrusion being able to fit into the corresponding strip-shaped slot.

[0008] Preferably, a fixing member is fixedly provided on one side of the inner wall of the central annular groove, and the inner sides of the two sets of fixing members can be sealed and fitted together.

[0009] Preferably, the bottom end of the upper connecting link body has a strip-shaped protrusion and an inwardly shaped groove. The depth of the shaped groove is half the thickness of the upper connecting link body. Two sets of semi-circular grooves are formed on the left side of the shaped groove, and two sets of semi-circular protrusions are formed on the right side of the shaped groove. The two sets of semi-circular protrusions can be fitted into the corresponding two sets of semi-circular grooves.

[0010] Preferably, the fixing component includes a fixing plate and a triangular protrusion. The fixing plate is fixed on one side of the center of the upper connecting chain link body. A threaded hole is opened in the center of the fixing plate, and a bolt is threaded into the center of the threaded hole. Multiple sets of triangular grooves are opened on the front side of the fixing plate, and multiple sets of triangular protrusions are fixed on the rear side of the fixing plate.

[0011] Preferably, the multiple sets of triangular protrusions are correspondingly fitted into the multiple sets of triangular grooves, and the multiple sets of triangular protrusions and triangular grooves are all horizontally fitted.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This is a super corrosion-resistant and ultra-strong vertical mining connecting chain link. It can be assembled and used by combining the upper and lower connecting chain links. This design further improves the load-bearing capacity of the connecting chain link during use and further enhances its stability. The metal coating on the outer wall of the upper and lower connecting chain links forms a physical barrier and utilizes the sacrificial anode effect to achieve corrosion protection, thereby increasing the service life of the connecting chain link.

[0014] This super corrosion-resistant and ultra-strong vertical connecting chain ring for mining uses two sets of connecting chain rings that can be fitted together via a strip-shaped groove and strip-shaped protrusion on the upper connecting chain ring. This design reduces the lateral load on the connecting chain ring, effectively preventing cracking from the center of the connecting chain ring. The triangular groove and triangular protrusion on the fixing plate can bear longitudinal force, thereby reducing uneven stress distribution caused by the load. By assembling the upper and lower connecting chain rings, it is possible to quickly replace and reassemble them if one set is damaged, thereby reducing safety hazards. Attached Figure Description
