The head nudge section is an important part of mechanical equipment, especially in coal mining machinery, such as scraper conveyor plays a key role. The following is a detailed analysis of the head nudge section:
Definition and Function
The head pushing section is an important structure used for installing, supporting and pushing the head section in the scraper conveyor or other similar equipment. It realizes the forward movement or adjusts the position of the whole equipment to meet the production demand through the connection with the head section. The design and structure of the header pushing part need to have enough strength and rigidity to ensure the stability and safety of the equipment in the process of pushing.
Structural Components
The specific structure of the head pusher section may vary depending on the model and manufacturer of the equipment, but generally contains the following main parts:
- Pushing beam: as the main load-bearing and force-transferring parts of the head pusher section, it is connected with the head section. Head coupling bottom beam: it is used to connect with the head section.
- Head coupling bottom beam: Used to make a firm connection with the head section to ensure the stability of the head in the nudging process.
- Front-end coupling beam and front-end balancing beam: these parts may be used to further enhance the overall rigidity and stability of the nose nudge section, to prevent deformation or damage during the nudge process.
In addition, some advanced design of the nose pusher section may also include hydraulic height adjustment device, etc., to adapt to the height adjustment needs of different working environments.
Principle of operation
The working principle of the nose lift section usually involves the following steps:
1. Connection and fixation: First, the head section is firmly connected to the head lift section to ensure the relative position of each component is stable.
2. Pushing operation: By operating the hydraulic cylinder or other power devices, the head nudging section generates a pushing or pulling force, which pushes the head section forward. In this process, the pushing crossbeam, the head coupling bottom beam and other components together bear and transfer the force.
3. Height adjustment (if applicable): For the head pusher section equipped with hydraulic height adjusting device, the height adjustment of the head section can be realized by adjusting the expansion and contraction amount of the hydraulic cylinder to adapt to different working requirements.
Application examples
Scraper conveyor is one of the indispensable equipments in the comprehensive mining face of coal mine. Its head nudge section realizes the continuous transportation of coal and the overall advancement of the equipment through the cooperative work with other components. With the continuous progress of technology and equipment upgrading, the design and performance of the header pushing section are also continuously optimized and upgraded.
Maintenance
In order to ensure the normal operation and prolong the service life of the head pusher section, it is necessary to carry out regular maintenance and repair work. This includes checking the wear and tear of each component, the loosening of fasteners, the oil level and pressure of the hydraulic system, etc.. At the same time, regular cleaning and lubrication of the equipment is also required to minimize the impact of friction and wear on the performance of the equipment.
In summary, the head nudge section is one of the important components in mechanical equipment, and its structure, function and working principle have an important impact on the overall performance and stability of the equipment. In the process of use need to pay attention to the maintenance and repair work to ensure its normal operation and extend the service life.
