Description
Technical Field
[0001] The utility model relates to the technical field of tunnel construction equipment, in particular to an excavating device for tunnel construction. Background Art
[0002] Tunnels are engineering structures buried in the ground, and are a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, and mining tunnels. The definition of a tunnel is: "a tunnel with a cross-sectional area greater than 2m2 that is built for a certain purpose and in any way under the ground with a prescribed shape and size." 2 The cave chamber.
[0003] During tunnel construction, dust is generated in every operation process and link. This dust is not only harmful to human health, but may also cause explosion accidents. Dust can cause pneumoconiosis when people inhale it into their respiratory organs for a long time. This is an extremely serious occupational disease that damages respiratory function, affects working ability, and even shortens working life or causes death. In addition, dust enters the oil and moving parts of mechanical equipment, which will pollute the equipment, accelerate the wear of moving parts, and shorten the service life of the equipment.
[0004] Therefore, how to provide an excavation device for tunnel construction with a dust reduction function has become a technical problem to be solved by those skilled in the art. Utility Model Content
[0005] The technical problem to be solved by the utility model is how to provide an excavating device for tunnel construction with a dust reduction function.
[0006] To achieve the above-mentioned purpose, the utility model provides an excavation device for tunnel construction, comprising: a frame, a mechanical arm is provided on the frame, and a bucket for excavating the tunnel is provided on the mechanical arm, a dust reduction pipe for dust reduction is provided on the mechanical arm, and the dust reduction pipe is a liquid channel, and the water inlet end of the liquid channel is connected to an external water source pipe, and the water outlet end is located above the bucket to form a dust reduction function.
[0007] The frame adopts the existing rotating structure available on the market in this field, which plays a role of fixed support and steering for the whole device. The mechanical arm is used to control the bucket according to actual needs, and the bucket is used to excavate tunnel construction. This method is common knowledge known in this field, so it will not be repeated. In actual use, the water inlet end of the liquid pipeline is connected to the external water source pipeline, and the water source is sprayed out through the water outlet end of the liquid channel to reduce the dust generated by the bucket during excavation, and a nozzle can be installed at the water outlet end of the liquid channel according to needs.
[0008] Preferably, an operating room is provided on the top of the frame.
[0009] The operating room is an operating space for the staff to operate the device. This method is common knowledge in the art and will not be described in detail.
[0010] Preferably, track wheels are provided at the bottom of the frame.
[0011] The crawler wheel design not only enables the frame to be mobile, but also enables the frame to adapt to various ground environments, avoiding certain limitations during use, thereby reflecting the practicality of the device.
[0012] Preferably, the robotic arm is a split structure, including an upper arm and a lower arm.
[0013] The split-structured mechanical arm can accurately adjust the position of the bucket during use. At the same time, during later replacement and maintenance, it is convenient to carry out split-type replacement and maintenance, thereby reducing the later replacement and maintenance costs, further reflecting the practicality of the device.
[0014] Preferably, the liquid channel is installed on the forearm of the robot arm via a fixing sleeve, and the liquid channel and the fixing sleeve are fully enclosed and connected through the fixing sleeve, and the fixing sleeve and the robot arm are welded.
[0015] The fully enclosed through-connection design ensures the stability of the connection between the liquid channel and the fixed sleeve, and the welding design ensures the stability of the connection between the fixed sleeve and the robotic arm. This design ensures the stability of the dust reduction pipe during use.
[0016] Preferably, the safety warning component includes a proximity sensor and a warning light, and the proximity sensor and the warning light are electrically connected to the operating room.
[0017] The design of the safety warning component ensures the safety of the device when in use. The proximity sensor and warning light both adopt existing structures on the market, and the electrical connection design facilitates the integrated control of the device in the operating room, reflecting the degree of automation of the device.
[0018] Preferably, the proximity sensor is mounted on the lower surface of the robot arm and is arranged vertically.
[0019] The design of the proximity sensor establishes a monitoring area under the robot arm to perform real-time monitoring of the area below the robot arm to prevent workers from accidentally entering and causing accidents.
[0020] Preferably, the warning light is installed on one side of the top of the rack.
[0021] When the proximity sensor detects that a person has entered the monitoring area, it transmits a signal to the operation room, causing the operation room to transmit a signal to the warning light, causing the warning light to sound, thus serving as a reminder to the person.
[0022] The beneficial effects of the utility model are:
[0023] 1. When the utility model is in use, the water inlet end of the liquid pipeline is connected to the external water source pipeline, and the water source is sprayed out through the water outlet end of the liquid channel to reduce the dust generated by the bucket during excavation. This not only protects the atmospheric environment in the tunnel, but also protects the physical condition of the staff to a certain extent. At the same time, it can improve the service life of the machinery to a certain extent, which is conducive to its popularization and use.
[0024] 2. When the utility model is in use, the proximity sensor is designed to establish a monitoring area within the range below the upper arm of the robotic arm, which is used for real-time monitoring of the area below the upper arm of the robotic arm to prevent workers from entering the area by mistake and causing accidents. When the proximity sensor detects that a person has entered the monitoring area, it transmits a signal to the operating room, causing the operating room to transmit a signal to the warning light, which makes the warning light sound and serves as a reminder to the personnel, reflecting the safety and practicality of the device when in use.
