Description

Technical Field

[0001] The present invention relates to the field of tunnel engineering construction, and in particular to a multifunctional tunnel trolley with integrated spray dust reduction and maintenance structure, which is used to reduce dust emission during tunnel advancement and provide a maintenance function for the trolley at the same time. Background Art

[0002] During tunneling, a large amount of dust is generated due to rock crushing, excavator operation, and movement of soil and rock. This dust not only affects the air quality inside the tunnel, increasing health risks for construction workers such as respiratory diseases and eye irritation, but also damages the equipment inside the tunnel, shortening its service life. In addition, dust also affects the line of sight during tunneling, increasing construction difficulty and safety hazards.

[0003] In order to reduce dust pollution during tunnel excavation, the commonly used methods include wet dust removal, ventilation dust removal and covering dust removal. However, most of these methods have problems such as low efficiency, high cost or inconvenient operation. For example, wet dust removal requires continuous spraying of water mist into the tunnel, which not only increases the consumption of water resources, but also requires additional equipment to provide water sources and spraying systems. Although ventilation dust removal can effectively remove dust from the tunnel, it requires a large ventilation volume and a long ventilation time, which increases energy consumption and cost. As an important tool for tunnel excavation, the performance status of the tunnel propulsion trolley directly affects the excavation speed and quality of the tunnel. Regular maintenance of the tunnel propulsion trolley is the key to ensuring its good performance. However, traditional trolley maintenance methods often require manual work, which is not only inefficient, but also has certain safety risks.

[0004] In summary, the traditional tunnel propulsion trolley has certain limitations and shortcomings. Therefore, an innovative technical solution is needed to solve these problems, which can effectively reduce dust pollution during the excavation process, and can also conveniently spray the trolley for maintenance, so as to improve construction efficiency and ensure construction quality. Summary of the invention

[0005] In view of the defects in the prior art, the purpose of the present invention is to provide a tunnel propulsion trolley that is movable during the construction process, can realize dust removal and maintenance integration, and reduce energy consumption. To achieve this goal, the present invention proposes a technical solution, which is characterized by the device having the characteristics of simple structure, convenient operation and easy mobility. In addition, the design of the present invention can also efficiently realize dust removal and maintenance integration, improve work efficiency and reduce energy consumption and carbon emissions.

[0006] On the basis of the above technical scheme, the present invention relates to a tunnel propulsion trolley with an integrated spray dust reduction structure, including a smoke sensor, a canopy, an integrated frame, a slide rail, a water pipe, a water pipe bracket, a universal wheel, a spray maintenance device, and a canopy recovery device. The integrated frame serves as the basic structure of the entire trolley, carrying and supporting the canopy, water pipes and other components. The spray maintenance device includes a nozzle, a steering slide rail and a shell. The spray direction is controlled by the steering slide rail. When the nozzle is downward, the water mist sprayed by the nozzle is used for dust reduction; when the nozzle is upward, the water sprayed by the nozzle is used for spraying and maintaining the tunnel wall. The water pipe is connected to the spray maintenance device to provide water to the nozzle. The opening and closing of the canopy is controlled by the partitioned smoke sensor design, and the spray dust reduction or wall maintenance mode is automatically switched to reduce the waste of water resources.

[0007] Compared with the prior art, the advantages of the present invention are:

[0008] 1. Integration of efficient dust removal and maintenance: The integrated spray dust reduction structure effectively controls dust during tunnel excavation, significantly reduces air pollution in the tunnel, and improves the construction environment. At the same time, the bidirectional nozzle design realizes the dual functions of spray dust removal and tunnel wall maintenance, improving equipment utilization and operating efficiency.

[0009] 2. Environmental protection and energy saving: During the spray dust removal process, by controlling the spray range and density of water mist, the tunnel wall can be fully, safely and evenly maintained, thus avoiding the waste of water resources, lowering energy consumption and reducing energy consumption and carbon emissions.

[0010] 3. Reduce labor intensity and safety risks: Reduce the need for manual operation, reduce the labor intensity of construction workers, reduce dust pollution at the construction site, and reduce the health risks of construction workers

[0011] 4. Improve construction efficiency: The integrated design of spray dust removal and maintenance functions reduces the time for equipment replacement and commissioning, and improves construction efficiency. At the same time, due to the design of the canopy, dust is effectively prevented from escaping, ensuring the cleanliness and tidiness of the construction environment.

[0012] In summary, the present invention uses a two-way nozzle to achieve spray dust reduction and trolley maintenance. Through the regional canopy design and smoke sensor, it can simultaneously achieve regional dust reduction in the construction area and maintenance of the tunnel wall, greatly reducing the waste of resources. The universal wheel is used to improve the mobility of the equipment, which is suitable for dust reduction work in various environments. The device has the effects of integrating efficient dust removal and maintenance, environmental protection and energy saving, reducing labor intensity and safety risks, and improving construction efficiency.

[0027] Smoke sensor 1 (2), smoke sensor 2 (3), smoke sensor 3 (4) are used to sense the dust in the regional environment, and respectively control canopy 1 (5), canopy 2 (6), canopy 3 (7) and the spray maintenance device (13) in the corresponding area to achieve regional dust reduction and tunnel wall maintenance. Universal wheel 3 increases the mobility of the device, which is convenient for use in different locations. The spray maintenance device (13) is composed of a spray head (14), a steering rail (15), and a shell (16). The spray head (14) is turned downward or upward through the steering rail (15). When turning downward, the water mist sprayed by the spray head is used for dust reduction. When turning upward, the water sprayed by the spray head is used for tunnel wall maintenance.

[0028] When in use, according to construction requirements and site conditions, the trolley is moved to a designated position through the universal wheel (12), the water pipe (10) is connected to a water source, and the smoke sensor (2), the smoke sensor (3) and the smoke sensor (4) monitor the dust in the air and set the spray maintenance device (13) in the area to a spray dust reduction mode or a spray maintenance mode according to actual needs, thereby greatly reducing the waste of water resources. The canopy 1 (5), the canopy 2 (6) and the canopy 3 (7) are composed of a retractable bracket and waterproof materials, and are connected to the integrated frame (8) through a slide rail (9) to achieve opening and closing operations. During dust removal operations, the canopy 1 (5), the canopy 2 (6) and the canopy 3 (7) are closed to completely cover the top of the trolley to prevent dust from slipping out from the top; and during tunnel wall maintenance, the canopy 1 (5), the canopy 2 (6) and the canopy 3 (7) are opened to expand and cover the area on the top of the trolley to facilitate maintenance operations.
