Description

Technical Field

[0001] The present invention relates to the technical field of coal mine drills, and particularly to a support-type pneumatic water mill drill for coal mines. Background Art

[0002] In mining and underground operations, drilling operations are often required. The underground environment is extremely complex, with not only narrow space and dim light, but also flammable and explosive substances such as gas and coal dust, which pose extremely high requirements for the safety and reliability of drilling equipment.

[0003] However, the mainstream large drilling equipment on the current market is an electric water mill drill, which is a non-explosion-proof equipment and faces many challenges when used in coal mines. First of all, the electric water mill drill needs to be driven by electricity. In coal mines, the power supply system is often affected by multiple factors such as space limitations, equipment aging, and complex circuits, resulting in unstable power supply and difficulty in ensuring. Especially in areas far from the main power source, power supply becomes a major problem. This not only affects the normal use of the electric water mill drill, but also may cause equipment failures due to insufficient power supply, and even lead to safety accidents. Secondly, due to the presence of flammable and explosive substances such as gas and coal dust in coal mines, the electric water mill drill must meet strict explosion-proof requirements when in use. This requires a series of explosion-proof measures to be taken during the design, manufacture, installation, and use of the equipment to ensure safety during underground operations. However, the increase in explosion-proof measures not only increases the manufacturing cost of the equipment, but also increases the complexity and maintenance difficulty of the equipment, which seriously limits the efficiency and safety of working in mines. Therefore, there is currently a lack of a large drilling equipment that can adapt to the complex environment of coal mines, does not require electric drive, and meets explosion-proof requirements. Therefore, we provide a support-type pneumatic water mill drill for coal mines. Summary of the Invention

[0028] One side of the control box 9 is welded and cast on one side of the working platform 4, the bottom of the slideway 5 is welded and cast on the working platform 4, one end of the cylinder 3 is welded and cast on the working platform 4, the end of the cylinder 3 far from the working platform 4 is butted against the pneumatic motor 1, one end of the silencer 7 is butted against the pneumatic motor 1, one end of the base 6 is welded and cast at the bottom of the pneumatic motor 1, the inner surface of the base 6 is nested on the outer surface of the slideway 5 for sliding adjustment, one side of the slideway 5 is welded on the working platform 4 for fixation, one end of the transmission component 8 is butted against the end of the pneumatic motor 1 far from the cylinder 3, and one end of the water mill drill bit 2 is butted against the end of the transmission component 8 far from the pneumatic motor 1;

[0029] The pneumatic motor 1 serves as a driving part to drive the water mill drill bit 2 to perform drilling operations in cooperation with the transmission component 8. Using compressed air as the power, it does not require electric drive. The cylinder 3 serves as a propulsion device, and the telescoping of the cylinder 3 is controlled through the control box 9 to achieve the forward and backward operations of the water mill drill. The control box 9 is equipped with a pressure gauge and a control valve, which can detect the compressed air pressure and operate the reciprocating movement of the cylinder 3 and the start and stop of the pneumatic water mill drill. The working platform 4 is of a single-platform structure and is designed to be foldable and disassemblable. The pneumatic motor 1 is installed on the fixed slideway 5 through the base 6, and the slideway 5 and the working platform 4 together constitute a stable working platform.

[0030] In this embodiment, the staff can install the pneumatic motor 1 and the transmission component 8 on the base 6, fix the base 6 on the slideway 5, and then install the slideway 5 and the power assembly on the working platform 4 together. After adjusting the height and angle of the working platform 4 according to actual needs, start the pneumatic motor 1 by using the control box 9 to drive the water mill drill bit 2 to perform drilling operations. Control the telescoping of the cylinder 3 through the control box 9 to achieve the advancement and retraction of the water mill drill bit 2. After completing the drilling operation, fold and disassemble the working platform 4 for easy transportation and storage.

[0031] Working principle:

[0032] As Figure 1-2 shown, it is necessary to fixedly install the pneumatic motor 1 and its transmission component 8 on the newly made base 6, and firmly fix the base 6 on the slideway 5. Then, install the slideway 5 and the power assembly on the working platform 4 together to ensure the stability of the entire device. According to actual needs, the staff can adjust the height and angle of the working platform 4 to achieve the best working state. At this time, the activation of the control box 9 enables the pneumatic motor 1 to drive the water mill drill bit 2 to start drilling operations. At the same time, the staff can control the telescoping of the cylinder 3 through the control box 9, thereby realizing the advancement and retraction of the water mill drill bit 2 to ensure the accuracy and efficiency of drilling.

[0033] During the drilling operation, the pneumatic motor 1 serves as the driving component and works in coordination with the transmission component 8 to drive the water mill drill bit 2 to perform efficient drilling. The cylinder 3 serves as the propulsion device and cooperates with the operation of the control box 9 to control the advancement and retraction of the water mill drill bit 2 to ensure the smooth progress of the operation. During the operation, through the pressure gauge and the control valve, the staff can monitor the pressure of the wind pressure and the reciprocating operation of the cylinder 3 in real time to ensure that the entire system operates in a safe and efficient state.

[0034] After the operation is completed, the staff can quickly fold and disassemble the working platform 4 according to needs for easy transportation and storage of the equipment. Through this process, this pneumatic water mill drill can efficiently complete drilling tasks with a diameter of 200 mm and a depth of 350 mm in the underground environment, which can be completed in only 6 - 10 minutes, greatly improving the construction efficiency, and is simple and flexible to operate, and can adapt to the complex underground working environment.
