Description

Technical Field

[0001] This utility model belongs to the field of dust prevention and temperature regulation, and specifically relates to an air curtain type dust prevention and temperature regulation seat system for tunneling machines. Background Technology

[0002] Coal mine tunneling machines are mainly used for tunneling coal mine roadways. The cutting head is a key component for crushing coal and rock. Power is transmitted from the motor of the cutting unit to the reducer via a coupling. The reducer then reduces speed and increases torque before transmitting power to the cutting head via the main shaft of the cantilever section. The cutting teeth are specialized crushing tools mounted on the cutting head. Rotating the cutting head drives the cutting teeth to cut and crush the coal and rock. Although multiple mists of water are sprayed from inside the cutting head to cool the cutting teeth, eliminate sparks, and reduce the amount of dust generated during cutting at the working face, the dust generated during the tunneling machine cutting process is enormous, and internal spraying alone cannot effectively reduce the dust. Although some mines have installed dust removal systems, their use has certain limitations and cannot completely remove the dust generated at the working face. In addition, secondary dust generated during the loading and transportation of the tunneling machine results in a large amount of dust at the operator's position, which has a certain impact on their breathing, vision, and other systems. Furthermore, with the depletion of coal resources, the mining depth in some mines has increased year by year, reaching over 1,000 meters. The ground temperature in the tunnels is high, exceeding 30 degrees Celsius. Combined with the heat released from the electrical and hydraulic systems of the tunneling machine itself during operation, the local temperature at the operator's location can reach 40 degrees Celsius. This harsh working environment seriously affects the physical and mental health of the tunneling machine operators. Moreover, prolonged stable work in such high temperatures is impossible, impacting tunneling efficiency and safety. In addition, in some tunnels or adits close to the surface, the working face temperature is basically the same as the ground temperature. The low ambient temperature in winter also has a certain impact on the health of the operators.

[0003] Due to the limited working environment of tunneling machines, which are small, low, and prone to collisions, it is impossible to install a closed tunneling machine driver's cab to ensure a clean and cool space for the driver. As a result, the driver is completely exposed to dust and high temperature when operating the tunneling machine.

[0004] Based on this, this utility model proposes an air curtain type dustproof and temperature-regulating seat system for tunneling machines. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, namely, the limitation of the narrow, low, and easily bumped working environment of the tunneling machine, which makes it impossible to install an enclosed tunneling machine driver's cab to ensure a clean and cool space for the driver, and the problem that the driver is completely exposed to dust and high temperature environment when operating the tunneling machine, this utility model provides an air curtain type dustproof and temperature-regulating seat system for tunneling machines, including a drainage pipe, which is installed through one surface of the hollow seat, and multiple drainage pipes are evenly installed along the outer contour of the hollow seat;

[0006] The air supply pipe is connected to the air supply system, which supplies air through the hollow seat into the air supply pipe. The air supply pipe sprays the air outward in the form of an airflow, forming a closed space to surround the operator, thereby achieving dust prevention and temperature regulation.

[0007] In some preferred embodiments, the air supply system includes an air supply manifold and an air supply duct;

[0008] One end of the air supply manifold is sealed and connected to the other surface of the hollow seat, and the other end of the air supply manifold is sealed and connected to the air supply duct. The air supply duct is suspended on one side of the top of the tunnel.

[0009] In some preferred embodiments, an air conditioner is installed in the middle of the air supply manifold, the air conditioner being used to heat or cool the airflow within the air supply manifold.

[0010] In some preferred embodiments, the air supply manifold is equipped with a damper for adjusting the size and speed of the airflow.

[0011] In some preferred embodiments, the damper is installed between the air conditioner and the hollow seat.

[0012] In some preferred embodiments, the section connecting the air supply manifold to the air supply duct is a telescopic structure.

[0013] In some preferred embodiments, the air conditioner is installed between the damper and the air supply duct.

[0014] In some preferred embodiments, the air conditioner is supported on the tunneling machine and is electrically connected to the electrical control box on the tunneling machine.

[0015] In some preferred embodiments, the air supply duct is connected to a fan, and the fan is used to introduce airflow into the air supply duct.

[0016] The beneficial effects of this utility model are:

[0017] This invention introduces fresh air from a ventilation duct, which is then sprayed out through drainage pipes arranged around the hollow seat. These pipes densely surround the operator, forming an air curtain that protects them from dust generated during the tunneling machine's cutting process. This continuous flow of clean air keeps the operator from accessing the dust, providing a clean working environment. The hollow seat also maintains a consistent temperature with the airflow, ensuring a comfortable seating temperature for the driver. The operator can adjust the airflow speed and volume using the dampers, and the air conditioning system can regulate the supply air temperature.

[0018] By arranging the air supply system, a suitable temperature can be provided for tunneling machine operators in high-temperature or cold working environments, while effectively isolating dust, reducing the risk of silicosis for operators, and improving the comfort of tunneling machine operation, which has broad market application prospects.

[0022] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] like Figures 1-2 As shown, see Figure 1 This utility model provides an air curtain type dustproof and temperature-regulating seat system for tunneling machines, including a drainage pipe 12, which is installed through a surface of a hollow seat 5, and multiple drainage pipes 12 are evenly installed along the outer contour of the hollow seat 5;

[0025] The air supply pipe 12 is connected to the air supply system, which supplies air through the hollow seat 5 into the air supply pipe 12. The air supply pipe 12 sprays the air outward in the form of an airflow, forming a closed space to surround the operator, achieving dust prevention and temperature regulation. At the same time, the surface of the hollow seat 5 also maintains a consistent airflow temperature to achieve a suitable temperature effect.

[0026] The system provided by this utility model is installed inside a tunneling machine located in the middle of the tunnel. In this embodiment, the tunneling machine includes a cutting section 1, a loading mechanism 2, a tracked walking mechanism 3, an operating platform 4, an electrical control box 6, and a transport machine 7. All of the above structures are existing technologies, and the specific connection methods are not detailed here. While the seats in existing technologies are not hollow, this application uses a hollow seat 5, and the system is specifically installed on the hollow seat 5. The operating platform 4 is arranged on the left side of the tunneling machine, and the hollow seat 5 is placed in the center of the operating platform 4.

[0027] Specifically, "the drainage tube 12 is installed through a surface of the hollow seat 5" means:

[0028] The hollow seat 5 has a through hole on the side closest to the person, and a drainage tube 12 is welded into the through hole. Multiple drainage tubes 12 and through holes are evenly arranged along the outer contour of the hollow seat 5.

[0029] For further explanation of this utility model, see [link to relevant documentation]. Figure 1 The air supply system includes an air supply manifold 8 and an air supply duct 11;

[0030] One end of the air supply manifold 8 is sealed and connected to the other surface of the hollow seat 5, and the other end of the air supply manifold 8 is sealed and connected to the air supply duct 11, which is suspended on one side of the top of the tunnel.

[0031] For further explanation of this utility model, see [link to relevant documentation]. Figure 2 An air conditioner 9 is installed in the middle of the air supply manifold 8. The air conditioner 9 is used to heat or cool the airflow in the air supply manifold 8.

[0032] For further explanation of this utility model, see [link to relevant documentation]. Figure 2 The air supply manifold 8 is equipped with a damper 10, which is used to adjust the size and speed of the airflow.

[0033] In specific applications, the air supply duct 11 introduces clean airflow through the rear fan, which then enters the air conditioner 9 via the air supply manifold 8. After the air conditioner 9 heats or cools the air, it enters the hollow seat 5 through the air damper 10. The air damper 10 can adjust the airflow of the hollow seat 5. The air entering the hollow seat 5 is sprayed outward through the drainage pipes 12 distributed around the outer side of the hollow seat 5. The airflow forms a closed clean space that surrounds the operator, providing the operator with a clean and temperature-appropriate working environment.

[0034] Under the guidance of the drainage pipe 12, the airflow from all sides of the hollow seat 5 forms an air curtain, which effectively isolates external dust and ensures a good working temperature for the operator. The airflow also heats or cools the hollow seat 5 at the same time, ensuring the comfort of the passengers.

[0035] For further explanation of this utility model, see [link to relevant documentation]. Figure 2 The air vent 10 is installed between the air conditioner 9 and the hollow seat 5.

[0036] For further explanation of this utility model, see [link to relevant documentation]. Figure 1 The section connecting the air supply manifold 8 and the air supply duct 11 is a telescopic structure.

[0037] In particular, the present invention can prevent the connection between the air supply manifold 8 and the air supply duct 11 from failing when the tunneling machine is moving, and the telescopic structure can extend and retract the pipe.

[0038] For further explanation of this utility model, see [link to relevant documentation]. Figure 1 The air conditioner 9 is installed between the damper 10 and the air supply duct 11.

[0039] For further explanation of this utility model, see [link to relevant documentation]. Figure 1 The air conditioner 9 is supported on the tunneling machine, and the air conditioner 9 is electrically connected to the electrical control box 6 on the tunneling machine.

[0040] For further explanation of this utility model, see [link to relevant documentation]. Figure 1 The air supply duct 11 is connected to a fan, and the fan is used to introduce airflow into the air supply duct 11.
