Compartment elevator braking device

Abstract

The invention discloses a compartment elevator braking device. The compartment elevator braking device comprises a rack, an electromagnet, an electromagnet core, two band-type brake assemblies, a lower adjusting rod and a braking wheel, wherein the two band-type brake assemblies are symmetrically arranged at the left end and the right end of the electromagnet core. The compartment elevator braking device is characterized by further comprising a negative electrode loop wire, an electric bell, an alarming indicator lamp, a positive wire and a negative wire; each band-type brake assembly comprises a braking arm, a brake shoe, brake rubber and a brake rubber abrasion detection assembly, wherein the brake rubber is provided with a blind hole; each brake rubber abrasion detection assembly comprises a compression spring, a plastic screw, a plastic sleeve and a conductive metal step rod, wherein a stepped through hole is formed in the middle of the plastic screw, and a sharp head is arranged at the right end of the conductive metal step rod; and the upper ends of the braking arms of the two band-type brake assemblies are arranged at the left end and the right end of the electromagnet core of the electromagnet correspondingly. The compartment elevator braking device is novel in structure, accurate in control, capable of conducting prompting and alarming in time, convenient to install and maintain, safe, reliable and long in service life.

Description

technical field [0001] The present invention relates to an elevator, in particular to a car-type elevator braking device. Background technique [0002] Nowadays, high-rise buildings are inseparable from van elevators. Although van elevators can provide great convenience, safety is of paramount importance. The braking device of van elevators acts as a brake on van elevators. The electromagnetic brake type braking structure is mostly used in the braking device of the elevator type elevator. This electromagnetic brake type braking structure uses the electromagnet to control the action of the electromagnet core, thereby driving the brake arm to tighten or loosen. The action of opening the brake wheel, but in the process of use, the brake shoe installed on the brake shoe is easy to wear and tear. When the brake shoe is worn to a certain extent, it must be changed. In order to replace the brake shoe in time, it is necessary to understand the wear degree of the brake shoe. Master,...

[0002] Nowadays, van elevators are inseparable from high-rise buildings. Although van elevators can provide people with great convenience, safety is of paramount importance. The braking device of van elevators acts as a brake on van elevators. The braking device of the elevator adopts more electromagnetic brake type brake structure. This type of electromagnetic brake type brake structure uses electromagnets to control the action of the electromagnet core, thereby driving the brake arm to tighten or loosen. The action of opening the brake wheel, but in the process of use, the brake shoe installed on the brake shoe is easy to wear. When the brake shoe wears to a certain extent, it must be changed. In order to replace the brake shoe in time, it is necessary to understand the degree of brake shoe wear As far as I know, the current method is to check and estimate manually during maintenance, and decide whether to replace the brake skin. Due to large errors in the on-site inspection and estimation, and possibly due to the negligence of the inspectors, it is sometimes necessary to replace the brake skin. If it is not replaced in time, accidents may occur due to the failure of the brake to brake in time
