Embodiment Construction

[0010] The breathing ring anchoring nail has a circular anchoring ring, with wings 2 and holes 3 on the wall 1 of the anchoring ring, an opening 4 on the ring wall 1, and a connecting plate 5 on the bottom surface of the anchoring ring. There are more than two symmetrical openings 4 on the ring wall 1 , and the disconnected ring walls 1 are connected into one body through connecting plates 5 . There is a connecting hole in the center of the connecting plate, which is used for screwing with the anchor. The ring wall 1 and the connecting plate 5 are stamped from a whole plate without splicing.

Abstract

The invention discloses a breathing ring anchoring nail which is provided with an annular anchoring ring. Wings are formed in a hollow-out annular wall, a broken opening is formed in the annular wall, and a connection plate is arranged on the bottom face of the anchoring ring. The breathing ring anchoring nail not only has strong expansion and contraction functions, but also has a good anchoring function, and can well prolong service life of a lining. Contraction and expansion of the breathing ring anchoring nail along with contraction and expansion of a lining of an abrasion-resistant layer are achieved, wherein the breathing ring anchoring nail has a formwork function in an abrasion-resistant layer with a single layer and double-layer lining. The structural characteristic of the breathing ring anchoring nail enables connection between lining materials and between the lining materials and a breathing ring to be tighter, and the lining abrasion-resistant layer is made firm, so that the aim of long period use of the lining abrasion-resistant layer is achieved.

Description

1. Technical field [0001] The invention relates to catalytic cracking (decomposition) devices in the petrochemical industry and lining equipment for pipelines, in particular to skeleton anchors for double-layer lining wear-resistant layers. 2. Background Technology [0002] At present, in the lining equipment of catalytic cracking (decomposition) and pipelines in the petrochemical industry, many parts of the inner wall are equipped with heat-insulating and wear-resistant double-layer linings. The tortoise shell net is installed in one piece, so the construction is difficult; the stress superposition of the tortoise shell net often causes the lining to fall off. The construction of the side pull ring type anchor nail is more convenient, and its anchor ring is a closed ring; when the working temperature of the lining layer changes, the expansion and contraction of the anchor ring cannot be synchronized with the wear-resistant layer, which affects the working life of the wear-r...
