Coal mine transfer machine step by step self-movement is an important technology in coal mine production, which can realise the transfer machine's independent movement in the coal mine underground, and improve the production efficiency and safety. The following is a detailed analysis of the coal mine transfer machine step by step self-movement technology:
I. Definition and principle
Coal mine transfer machine step by step refers to the transfer machine through a specific drive device (such as hydraulic cylinders, motors, etc.), in the pre-set track or guide rail to achieve the gradual forward or backward movement. The principle usually involves the steps of sensors sensing the position information, control system issuing commands, and the drive device executing the action.
Structural features
The coal mine transfer machine step-by-step self-moving device is mainly composed of the following parts:
1. guide rail: as the track for the transfer machine to move, it ensures the stability and directionality of the transfer machine in the process of moving.
2. support cylinder and push cylinder: the support cylinder is used to lift the transfer machine to detach it from the ground, while the push cylinder is responsible for pushing the transfer machine to move along the guide rail.
3. Hydraulic control system: the action of the support cylinder and push cylinder is controlled by manipulating valves to realise the self-movement of the transporter. The hydraulic cylinder is powered by high pressure emulsion, and the working pressure is usually around 31.5MPa.
4. guide wheel frame: in the process of transferring the movement of the machine to play a guiding and stabilising effect, to ensure that the transfer machine can move smoothly along the guide rail.
Third, the operation process
The operation process of coal mine transfer machine is as follows:
1. support cylinder action: the first support cylinder piston rod out, lift the transfer machine landing section (generally 250mm), so that it is detached from the ground.
2. Pushing cylinder action: use the friction of the guide rail and the ground to push out the piston rod of the pushing cylinder with the ground guide rail as the pivot point. Under the action of pushing force, the transfer machine advances along the guide rail for one stroke (generally 1000mm).
3. Support cylinder reset: contract the piston rod of the support cylinder, and the transfer machine falls back to the ground. At the same time, the guide wheel frame lifts the guide rail off the ground.
4. Push cylinder reset: contract the piston rod of push cylinder, the guide rail advances one stroke. This cycle is repeated, so as to realise the self-transferring step of the transfer machine.
Application advantages
The application of coal mine transfer machine step by step self-movement technology brings the following advantages:
1. improve production efficiency: through the step by step self-moving technology, the transfer machine can move independently, reducing the manual operation and auxiliary time, and improving the production efficiency.
2. Reduced labour intensity: workers do not need to manually move the transfer machine, reducing labour intensity and work risk.
3. Improve safety: step self-transfer technology makes the movement of the transfer machine more smooth and controllable, reducing the risk of accidents caused by improper manual operation.
Coal mine transfer machine step by step technology is an indispensable part of modern coal mine production. It realises the autonomous movement of the transfer machine through a specific driving device and control system, which improves production efficiency and safety. With the continuous development and improvement of technology, the coal mine transfer machine step by step self-movement technology will play a more important role in coal mine production.
