Description

Manual adjustment steering mechanism of a hoisting and transporting machine

technical field

The invention relates to the technical field of hoisting and transportation, in particular to a manual adjustment steering mechanism of a hoisting and transportation machine.

Background technique

A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. Also known as crane, aerial crane, crane.

The main features of the tire crane are: the driving cab and the lifting control room are combined into one, which is evolved from a crawler crane (crawler crane). The shortcomings of crawler cranes (crawler cranes) that track shoes cause damage to the road surface are eliminated, and they belong to material handling machinery.

The bridge crane is a lifting device that is horizontally placed over the workshop, warehouse and stockyard for material lifting. Because its two ends are located on tall concrete pillars or metal supports, it is shaped like a bridge. The bridge frame of the bridge crane runs longitudinally along the tracks laid on the elevated sides on both sides, which can make full use of the space under the bridge frame to lift materials without being hindered by ground equipment. It is a kind of hoisting machinery with the widest range and the largest number.

Some working characteristics of lifting equipment are intermittent movements, that is, in a working cycle, the corresponding mechanisms for retrieving, moving, unloading and other actions work alternately. The development and use of cranes in the market are becoming more and more extensive. Due to the lack of outriggers for hoisting and hoisting, some accidents often occur, and the driving speed is faster than that of crawler cranes (crawler cranes); the operation is stable, the lifting capacity is large, and it can lift and walk within a specific range, but the road must be smooth and solid. , The tire pressure meets the requirements, and the hoisting from the ground shall not exceed 50CM; long-distance walking with a load is prohibited. In order to ensure the safety of the operation, it is basically forbidden to carry out hoisting operations without supporting legs in China at present. The types of steel wire ropes used for cranes include phosphating coated steel wire ropes, galvanized steel wire ropes and smooth steel wire ropes.

The following problems exist in the existing technology of manually adjusting the steering mechanism of lifting and transporting machinery: 1. Manually adjusting the steering mechanism of lifting and transporting machinery is inconvenient to operate, and usually requires multiple people to complete; 2. In addition, the existing lifting and transporting machinery manually adjusts the steering mechanism. Adjusting the structure of the steering mechanism is more complicated, which is not convenient for lifting small objects, and the efficiency of lifting and transportation is poor, so it is difficult to meet the needs of lifting and transportation.
