Coal mine transporter push seat

Coal mine transporter push seat is an important part of the coal mine comprehensive mining equipment, mainly used to connect the hydraulic support and scraper conveyor (or known as coal mine transporter), and through the push jacks to achieve mutual pivot between the two, alternately forward.

Coal mine transporter push seat is an important part of the coal mine comprehensive mining equipment, mainly used to connect the hydraulic support and scraper conveyor (or known as coal mine transporter), and through the push jacks to achieve mutual pivot between the two, alternately forward. The following is a detailed introduction to the coal mine conveyor pusher seat:

Definition and function

Definition: coal mine transporter push seat is a kind of connecting device, which is firmly connected between the hydraulic support and scraper conveyor, and realises the relative movement of the two through the action of push jack.

Function:

1. Connecting function: it connects the hydraulic support and scraper conveyor closely together to form a stable whole.

2. pushing role: under the action of pushing jack, pushing seat can drive the scraper conveyor to move forward, at the same time, the hydraulic support also acts as a pivot point to move, to achieve alternating forward movement.

3. Supporting role: in the process of pushing, the pushing seat also plays the role of supporting the scraper conveyor, to ensure its stability and safety in the process of moving.

Structure and composition

The specific structure and composition of the pusher seat of coal mine conveyor may vary according to different manufacturers and models, but generally includes the following main parts:

- Connection parts: such as bolts, pins, etc., which are used to firmly connect the pushover seat to the hydraulic support and scraper conveyor.

- Push jack: It is the key part of push seat to achieve the function of pushing, and drive the scraper conveyor to move through its telescopic action.

- Base: as the support structure of the pusher, it is usually connected with the base of the hydraulic support.

- Guiding device: such as guide sleeve, slide rail, etc., which is used to ensure the smoothness and accuracy of the pusher in the process of moving.

Working Principle

The working principle of the pusher seat of coal mine conveyor is as follows:

1. Lowering column unloading: before moving the stand, firstly, the column of hydraulic support is unloaded through the operating valve to lower the height of the stand.

2. Push jack work: Afterwards, the operating valve makes the high pressure liquid enter the piston rod chamber of push jack, and at the same time, the piston chamber returns to the liquid. At this time, taking the conveyor as the fulcrum, the cylinder body of the push jack moves forward, thus driving the push seat and scraper conveyor together to move towards the coal wall.

3. The support moves forward: when the scraper conveyor moves to a predetermined position, the column of the hydraulic support is operated again, so that it raises and supports the roof. At this time, the push jack continues to work, using the stand as a pivot point and the piston rod extends to further push the scraper conveyor towards the coal wall.

Application and Importance

The coal mine conveyor pushover seat plays a vital role in the comprehensive mining operation of coal mines. It can not only realise the effective connection and alternate forward movement between the hydraulic support and scraper conveyor, but also ensure the continuity and stability of the whole comprehensive mining operation process. With the continuous development and progress of coal mining technology, the performance requirements of the pushover seat are getting higher and higher. Therefore, its structural strength, wear resistance, sealing and other factors need to be fully considered in the design and manufacturing process to ensure that it can operate stably for a long time and meet the production requirements.

Precautions

When using the push seat of coal mine conveyor, the following matters need to be paid attention to:

1. Regular inspection: Regularly inspect and maintain the pusher seat to ensure that the connecting parts are tight, the guiding device is flexible, and the pusher jack works normally.

2. standard operation: strictly follow the operating procedures to move the frame and push the operation, to avoid damage to the equipment or safety accidents caused by improper operation.

3. Timely replacement: for the serious wear and tear or damage to the pusher seat parts, should be replaced in a timely manner to ensure the overall performance and safety of the equipment.

To sum up, coal mine conveyor pusher seat is an important part of coal mining equipment, and the stability and reliability of its performance is crucial for the whole process of comprehensive mining operation. Therefore, it is necessary to pay enough attention and concern in the process of use.
