Abstract

The invention discloses a protective device for a hanging basket travel limit switch, which comprises a protective cap, wherein the protective cap is buckled at the end part of a contact of the limit switch, and the cap of the protective cap covers the connecting part of the contact and a shell of the limit switch. Through buckling on the protective cap on the contact, the condition that various building material particles fall into the gap between the contact on the limit switch and the shell in the use process of the limit switch is avoided, so that the protection of the limit switch is realized, and the problem that the contact is blocked and cannot work due to the building material particles is avoided.

Description

Hanging flower basket travel limit switch protector

Technical Field

The invention belongs to the field of instrument protection, and particularly relates to a hanging basket travel limit switch protection device.

Background

The limiter is actually a safety device of the hanging basket, and once the basket body has a top impact phenomenon, the limiter can automatically touch a limiting baffle at the upper end of the steel wire rope, so that the building hanging basket automatically stops moving.

The limiter is divided into an upper limiter and a lower limiter, the upper limiter is arranged at a working position where the cage is allowed to be lifted, and the overtravel of the cage (the distance between the high position of the cage and the low position of the top beam) is not less than 3 m. When the suspension cage rises to reach the limited height, the limiting stopper acts to cut off the power supply; the lower limiting stopper acts before the cage touches the buffering device, and when the cage descends to the lower limiting stopper, the limiting stopper should automatically cut off the power supply to stop the descending of the cage.

In the electric hanging basket, the limiter is mainly used for controlling the lifting of the hanging basket so as to avoid the problem of lifting faults caused by circuit problems. When the hanging basket equipment exceeds the limit set by manpower, the power supply is automatically cut off, thereby ensuring the safety of constructors.

However, at present, construction personnel are carried by a hanging basket to carry out painting or painting construction inside and outside a building, and in the construction process, various dust particles, paint particles or cement particles and other building material particles easily fall into the contact gap of the stopper, so that the stopper contact is blocked, and the stopper is damaged to cause construction safety accidents.
