In industrial production, industrial equipment is one of the indispensable tools, which not only improves work efficiency, but also reduces labor intensity. In this era of increasing automation, there is still a special kind of industrial equipment-manual industrial equipment, which relies on human operation to work, among which, human handle, as an important part, plays a vital role.
I. Definition and Classification
1. Manual industrial equipment: This kind of equipment is mainly driven and controlled by manpower, and is usually used in some miniaturization or specific occasions. Common manual industrial equipment includes manual hydraulic truck, manual hoist, etc.
2. Manual handle: refers to the handle part used to manipulate or control manual mechanical equipment, which is mainly divided into two types: rotary handle and push-pull handle. These two different types of handles have different characteristics and application scenarios, so it is necessary to choose the appropriate type according to the actual situation in the actual application process.
Second, the structure and working principle
A human-powered handle is generally composed of three parts: a handle bar, a connecting piece and a transmission mechanism. Wherein, the handle bar is the part directly contacted by the user; The connecting piece is used for connecting the handle rod with the transmission mechanism; The transmission mechanism is the core component to realize force transmission.
When a worker holds the handle and applies a certain force (such as pushing/pulling/rotating), the force is transmitted to the transmission mechanism through the connector, and then converted into the required power form (such as linear motion or rotating motion) through a series of mechanical devices, so as to complete the corresponding work task.
Third, the advantages analysis
Although with the development of science and technology, many traditional processes that relied on manual operation have been replaced by modern intelligent production lines, the manual handle mechanism still has its unique advantages:
1. High flexibility: it is not limited by power supply and can be used in any environment;
2. Low maintenance cost: simple structure and easy maintenance;
3. Strong reliability: compared with the electronic control system, it is less prone to failure;
4. Low energy consumption: it can operate normally without consuming electric energy or other energy sources.
Fourth, the application field
At present, in the following scenes, you can also see a lot of use of human handles:
1. Logistics industry: such as trolleys used to carry goods in warehouses;
2. Construction: In some aerial work, ropes will be used together with manual hoists to lift heavy objects;
3. Manufacturing: some machine tools need manual position adjustment, such as turning the handwheel;
In a word, although today's society has entered the stage of high automation, in many cases, the human handle is still an indispensable choice. Its unique value lies in its ability to adapt to various complex and changeable work needs and its high stability and economy, so it will occupy an important position for a long time to come.
