Mechanical switch device

Abstract

The invention discloses a mechanical switch device, which comprises an inclined grate bar support seat (17) and an inclined grate bar (16). A shaft sleeve (3) is arranged on the shaft (1), the inner diameter of the shaft sleeve (3) is larger than the outer diameter of the shaft (1), and the shaft sleeve (3) rotates flexibly; arcs are respectively arranged on both sides of the shaft sleeve (3) shaped working arm (4) and counterweight arm (6); the two sides under the head of the arc-shaped working arm (4) are respectively provided with pin lugs (5), and a flat iron is set between the two pin lugs (5). (14); a counterweight (7) is provided above or below the tail of the counterweight arm (6); a stopper (10) is provided on the support seat (17) of the inclined grate bar, and the stopper (10) It is located under the counterweight arm (6); a proximity switch (15) is provided under the flat iron (14), and the proximity switch (15) is connected to the digital input module of the PLC through wires; the structure is simple, the production is simple, and the cost is low , easy to install, high reliability, ensure the safety of production and equipment, and effectively improve the economic benefits.

Description

[0001] Technical field: [0002] The present invention relates to the field of electromechanical technology, specifically a mechanical switch device, which is used for reliable control of equipment under abnormally harsh working conditions such as high temperature and high humidity, and replaces expensive and unsuitable hot metal detectors (hereinafter Thermal detection), cold metal detectors (hereinafter referred to as cold detection), and high-temperature laser ranging sensors (hereinafter referred to as laser sensors) and other sensors are widely used in the control of electrical equipment. [0003] Background technique: [0004] Taking the 1# cooling bed forward chain used for steel pipe production as an example, the production process in the automatic state is as follows: after the steel pipe is rolled by the sizing host, the roller table rotates to transport the steel pipe to the baffle at the end of the roller table. When the high-temperature steel pipe is detected, a si...
