Description

Novel anticollision hoist

Technical Field

The utility model relates to a hoist technical field, concretely relates to novel anticollision hoist.

Background

The crane refers to a multi-action crane for vertically lifting and horizontally carrying heavy objects within a certain range. The crane mainly comprises a hoisting mechanism, a running mechanism, a luffing mechanism, a slewing mechanism, a metal structure and the like. The hoisting mechanism is the basic working mechanism of the crane, mostly consists of a hanging system and a winch, and also lifts heavy objects through a hydraulic system. The running mechanism is used for longitudinally and horizontally moving a heavy object or adjusting the working position of the crane and generally comprises a motor, a speed reducer, a brake and wheels. The amplitude variation mechanism is only arranged on the jib crane, the amplitude of the jib crane is reduced when the jib crane is lifted up, the amplitude of the jib crane is increased when the jib crane is lifted down, and the jib crane is divided into a balanced amplitude variation mode and a non-balanced amplitude variation mode. The slewing mechanism is used for enabling the arm support to slew and consists of a driving device and a slewing bearing device. The metal structure is the framework of the crane, and the main bearing parts such as a bridge frame, an arm support and a portal frame can be box-shaped structures or truss structures, can also be web structures, and can use section steel as a supporting beam.

When the crane lifts some bulky goods in the use process, because the possible mass of goods distributes unevenly, the slope is likely to appear, and the lifting hook is bulky in addition, and the great quality of the bulky quality of volume, especially rise and descend the in-process, under the effect of the inertial force of goods, the pendulous nature of lifting the steel cable is great, leads to lifting hook and field device to bump very easily, damages the lifting hook, and serious still can appear the incident, then we propose a novel anticollision crane and solve the problem.
