specific Embodiment approach

[0018] Specific implementation: the device adopts a bolt-free external connection form: after the explosion-proof steel sleeve female head 9 and the explosion-proof steel sleeve male head 10 are docked, a hole is provided outside the explosion-proof steel sleeve male head 10, and a U-shaped pin 6 is installed in the hole. It can fix the two joints. Without the help of fastening tools, manual fast docking operation on explosion-proof electrical equipment can be realized, which can significantly reduce the labor intensity of operators and improve the installation and maintenance efficiency of explosion-proof electrical equipment. There are two ways to prevent explosion: using high-strength flame-retardant materials and reducing the explosive gas inside the joint. The design of this device has to design with above-mentioned two kinds of approaches. Explosion-proof steel sleeve female 9 and explosion-proof steel sleeve male 10 use high-strength Kevlar flame-retardant braiding lay...

Abstract

The invention discloses an A1 type anti-explosion quick coupler for an underground coal mine. The A1 type anti-explosion quick coupler comprises an anti-explosion steel jacket female head (9), wherein an anti-explosion steel jacket male head (10) is connected with one end of the anti-explosion steel jacket female head. The A1 type anti-explosion quick coupler has the benefits as follows: the device adopts a bolt-free two-stage explosive-proof structure, is in accordance with the explosion-proof criteria in the coal mine and free of other fastening tools, can realize manual and quick butt joint operation of the anti-explosion electric apparatus, obviously reduces the labor intensity of operation workers, and improves the efficiency of installation and maintenance of the anti-explosion electric apparatus; a Kevlar flame-retardant braid layer is arranged in the inner cavity of the device, so that the inner cavity explosive-proof gas volume can be reduced, and the explosive-proof capability can be obviously improved.

Description

technical field [0001] The invention relates to an explosion-proof quick joint, in particular to an A1 type explosion-proof quick joint under a coal mine, which belongs to the field of quick joint devices. Background technique [0002] Cables in coal mines power underground equipment. Under the strict explosion-proof requirements of coal mines, how to realize the fast connection between cables is the key to reduce the labor intensity of workers and improve the efficiency of underground work. [0003] The quick connector is an accessory for connecting products. By using the quick connector, the products can be seamlessly connected. According to the type, quick connectors can be divided into quick connectors for air, quick connectors for oxygen fuel gas, quick connectors for gas and liquid, quick connectors for oil pressure, quick connectors for inert gas, quick connectors for cooling water and oil, and semiconductor quick connectors. The quick connector can make the connect...
