Description

Technical Field

[0001] The invention specifically relates to a high-strength stainless steel bracket, and belongs to the technical field of flame detector mounting brackets. Background Art

[0002] A flame detector is a fire detector that responds to the optical characteristics of a fire, that is, it detects the light intensity of a burning flame and the flickering frequency of the flame. The detector is generally installed at twice the height of the highest target in the protected area. Within the effective range of the detector, it cannot be blocked by obstacles, including transparent materials such as glass and other partitions, while being able to cover all targets and areas that need protection, and is convenient for regular maintenance. The detector is generally installed at a downward tilt of 30-45°, so that it can look both downward and forward. When the detector is installed, it needs to be fixed to the installation position by a bracket. Existing brackets are generally iron castings, and the detection inclination of the detector is generally achieved by universal ball or joint locking. When existing brackets are used for oil, gas and electrical pipeline monitoring on offshore platforms, the platform's bumps and vibrations will cause the spring washers for inclination positioning to fail, and the bolts will loosen. The bracket is pulled down by the weight of the detector, deviating from the monitoring position, resulting in monitoring failure. In addition, ordinary brackets are prone to corrosion in the high-salt and high-humidity environment of the ocean. Summary of the Invention

[0013] Furthermore, the bracket inclination angle is adjusted as follows:

[0014] A. Pre-assembly: Install the bracket arm, rear mounting bracket, adjustment slide, and pin. First, movably insert the convex posts of the two rotating seats into the large circular holes of the bracket arm. Then, insert the pin through the convex circular hole, the axial holes of the two rotating seats, and the other convex circular hole in sequence and screw it onto the nut body.

[0017] D. After the bracket is solidified, tighten the pin and nut body for a second time, and fix the beam plate of the main support to the installation position.

[0018] Furthermore, the installation process of the upper components of the cup holder is as follows: first, according to the circumferential angle between the main support installation position and the monitoring point, the hanging rod is movably inserted into the cylinder seat and passed out from the top of the hanging hole; according to the circumferential angle, the gear disc of the hanging rod is engaged with the positioning gear ring to complete the circumferential limitation, and then, the first anti-slip screw and the second anti-slip screw are fixed to the cylinder seat to complete the axial limitation and circumferential limitation of the hanging rod; finally, the flame detector housing seat is fixed to the bottom of the hanging rod by welding or plugging in the bolts.
