Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0025] Please combine Figure 1 This invention discloses a sidewall auxiliary netting device 2, which is applied to a tunneling and anchoring machine 1. The sidewall auxiliary netting device 2 is mounted on the tunneling and anchoring machine 1. After the tunneling and anchoring machine 1 completes the face excavation operation, the sidewall auxiliary netting device 2 performs anchoring operation, pressing the anchor net 3 tightly against the sidewall to complete the laying of the anchor net 3 on the sidewall.

[0026] Please combine Figures 2 to 4 The side-mounted auxiliary netting device 2 includes a fixed frame 21, a first drive component 22, a first lifting frame 23, a second lifting frame 24, and a lifting component 26. The fixed frame 21 is the main structural component, playing a primary role in fixing and bearing loads. The first drive component 22 is mounted on the fixed frame 21, and the first lifting frame 23 is connected to the first drive component 22 and movably connected to the fixed frame 21. The second lifting frame 24 is movably connected to the first lifting frame 23. One end of the lifting component 26 is connected to the fixed frame 21, and the other end bypasses the first lifting frame 23, away from the fixed frame 21, and connects to the second lifting frame 24. Using a single first drive component 22, the first lifting frame 23 and the second lifting frame 24 can be raised or lowered simultaneously, which improves the efficiency of lifting the anchor netting 3, greatly increases the efficiency of anchor netting 3 laying, and reduces the labor intensity of operators. Simultaneously, the anchor netting 3 has a large travel distance, allowing for a large travel distance in a small space, resulting in a compact structure and reduced device size and space occupation.

[0027] It should be understood that the first lifting frame 23 and the fixed frame 21 move in a directional sliding manner, ensuring that the first lifting frame 23 can only move up and down, while horizontal movement is restricted. The second lifting frame 24 also moves in a directional sliding manner with the first lifting frame 23; when the first lifting frame 23 moves, the second lifting frame 24 will also move. The lifting component 26 is the transmission device connecting the fixed frame 21 and the second lifting frame, and its amplified stroke characteristic allows for rapid lifting of the anchor net 3. The combination of the first lifting frame 23 and the second lifting frame 24 not only amplifies the travel distance by at least 100%, but also doubles the lifting speed, thus improving work efficiency.

[0028] Optionally, the lifting component 26 includes a lifting chain and a sprocket. The sprocket is fixedly connected to the first lifting frame 23. One end of the lifting chain is connected to the fixed frame 21, and the other end passes around the sprocket and is connected to the second lifting frame 24. In this embodiment, the sprocket is located at the end of the first lifting frame 23 that is away from the fixed frame 21 in the sliding direction, thus achieving a larger stroke range. This makes full use of the installation space, achieving a larger range of movement with a device of the smallest possible size, thereby improving the laying efficiency of the anchor net 3.

[0029] Of course, in some other embodiments, the lifting component 26 can be made of pulleys and belts, or pulleys and steel ropes, etc., which also have similar technical effects, and no specific limitation is made here.

[0030] Optionally, the fixed frame 21 is provided with a first slide rail, along which the first lifting frame 23 moves; the first lifting frame 23 is provided with a second slide rail, along which the second lifting frame 24 moves; the sliding directions of the first lifting frame 23 and the second lifting frame 24 are the same. Optionally, the first driving component 22 is a hydraulic cylinder, a linear motor, or a linear pneumatic cylinder, etc. The first driving component 22 drives the first lifting frame 23 to move along the first slide rail, and at the same time, the first lifting frame 23 drives the second lifting frame 24 to move along the second slide rail via a lifting chain. In other words, the first lifting frame 23 and the second lifting frame 24 move simultaneously, which results in higher lifting efficiency for the anchor net 3 and higher laying efficiency for the anchor net 3. In this embodiment, the first driving component 22 is a telescopic hydraulic cylinder.

[0031] In this embodiment, both the first slide rail and the second slide rail are arranged along the first direction, that is, both the first lifting frame 23 and the second lifting frame 24 move along the first direction, which is the extension and retraction direction of the telescopic cylinder.

[0032] Please combine Figure 5 and Figure 6Optionally, the second lifting frame 24 is provided with a hook 25 for connecting the anchor net 3. The anchor net 3 can be a sheet net or a roll net. The hook 25 can be a lug or a hook, etc. If it is a sheet net, the hook can be directly inserted into the mesh at one end of the anchor net 3. When the second lifting frame 24 rises, it can lift the anchor net 3, which facilitates the laying of the anchor net 3, improves laying efficiency, and reduces the labor intensity of workers. If it is a roll net, the hook of the second lifting frame 24 is inserted into the mesh at one end of the roll net. During the rising process of the second lifting frame 24, the roll net is unrolled and laid out under its own weight, realizing the lifting and laying of the anchor net 3.

[0033] Optionally, a limit switch is provided on the first lifting frame 23. The side-mounted auxiliary netting device 2 also includes a control component, which is connected to the first drive component 22. It should be understood that the limit switch is communicatively connected to the control component. The limit switch is used to detect the lifting position of the first lifting frame 23 or the second lifting frame 24. When the first lifting frame 23 or the second lifting frame 24 is detected to have reached a preset position, the control component controls the first drive component 22 to stop. In this embodiment, the first drive component uses a telescopic cylinder, and the control component includes a hydraulic control device. The hydraulic control device is designed with a multi-way valve, a pressure regulating valve, and a balance valve, etc., which can realize the start and stop of the telescopic cylinder, the telescopic speed, the cylinder pressure, etc., improving the smoothness, safety, and reliability of the telescopic cylinder movement. The control component can also input control commands or operate control handles or buttons, etc., to realize human-machine interaction or manual intervention.

[0034] Optionally, the ends of the first and second slide rails are respectively provided with buffer limiting components, which can play a buffering and limiting role, preventing the first lifting frame 23 and the second lifting frame 24 from disengaging from the slide rails during sliding, and also reducing impact collisions and extending the service life of the equipment. The buffer limiting components include, but are not limited to, polyurethane rubber blocks, which can play a buffering role when the stroke is in place.

[0035] It is understandable that, based on the actual required lifting distance, a suitable type of hydraulic cylinder can be selected to meet the lifting stroke requirements.

[0036] Optionally, the sidewall auxiliary netting device 2 also includes a retractable push rod connected to the second lifting frame 24. A pressure roller is provided at the end of the push rod away from the fixed frame 21, and the pressure roller is used to adhere the anchor net 3 to the sidewall. The push rod has at least two states: extended and retracted. When the sidewall auxiliary netting device 2 is not in operation, the push rod is in the retracted state to reduce space occupation and prevent interference with the sidewall or other components. When the sidewall auxiliary netting device 2 is in operation, such as when the telescopic cylinder is extended, the push rod is in the extended state to press the anchor net 3, so as to better adhere the anchor net 3 to the sidewall, improving the laying efficiency and quality of the anchor net 3. The push rod can be powered by a hydraulic cylinder, pneumatic cylinder, linear motor, etc., without specific limitations.

[0037] Optionally, the push rod is equipped with a pressure roller, which is used to hold the anchor mesh 3. During the ascent of the second lifting frame 24, the push rod is raised along with it, and the pressure roller holds the anchor mesh 3 and rolls up along the side, thereby making the anchor mesh 3 fit the side better and improving the laying quality. The pressure roller can roll relative to the anchor mesh 3 to avoid damaging the anchor mesh 3 and to improve the smoothness of the movement of the push rod and the pressure roller.

[0038] Please continue to combine Figure 1 The present invention also provides a tunneling and anchoring integrated machine 1, including an installation platform 11 and a side-side auxiliary net hanging device 2 as described in any of the foregoing embodiments, wherein the side-side auxiliary net hanging device 2 is disposed on the installation platform 11.

[0039] Optionally, the installation platform 11 is equipped with a sliding mechanism, which is connected to the sidewall auxiliary netting device 2. This sliding mechanism moves the sidewall auxiliary netting device 2 towards or away from the sidewall. The sliding mechanism can move the entire sidewall auxiliary netting device 2 in a second direction, which is laterally, i.e., the direction of extension and retraction of the push rod. This second direction is perpendicular to the first direction. When the sidewall auxiliary netting device 2 is in operation, the sliding mechanism can move the entire device closer to the sidewall to facilitate the laying of the anchor netting 3, improving laying efficiency and quality.

[0040] In this embodiment, the two sides of the installation platform 11 are respectively provided with side auxiliary netting devices 2. The two side auxiliary netting devices 2 can work at the same time, that is, the anchor nets 3 are laid on the sides at the same time, which improves the work efficiency.

[0041] It should be noted that the movement of the telescopic cylinder, push rod, and sliding mechanism in this embodiment are all powered by the hydraulic power system of the integrated tunneling and anchoring machine 1. The control components can also be integrated on the installation platform 11 or on other carriers of the integrated tunneling and anchoring machine 1. This design has a high degree of integration and a compact structure, eliminating the need for additional power units, which helps to reduce equipment costs, size, and space occupation.

[0042] The working principle of the side-support auxiliary netting device 2 provided in this embodiment of the invention is roughly as follows: After the tunneling and anchoring machine 1 completes the face excavation, the sidewall auxiliary netting device 2 needs to perform anchoring operations. First, the sliding mechanism moves the entire sidewall auxiliary netting device 2 to the sidewall where netting needs to be laid. The second lifting frame 24 is attached to one end of the roll-shaped anchor net 3, and the telescopic cylinder is activated, driving the first lifting frame 23 and the second lifting frame 24 to rise. The roll-shaped anchor net 3 will also rise accordingly, and at the same time, the roll-shaped anchor net 3 will unfold vertically under its own weight and be laid on the sidewall. The anchor net 3 is then pressed tightly against the sidewall, completing the laying of the anchor net 3 on the sidewall.

[0043] Optionally, when the telescopic cylinder is activated, the push rod extends, and the pressure roller presses the anchor net 3 against the side, achieving a better fit between the anchor net 3 and the side; that is, laying the net and applying the anchor net 3 to the side are performed simultaneously. In some embodiments, after the net is laid, the push rod can extend again, press the anchor net 3, and roll it along the side to ensure a better fit between the anchor net 3 and the side; that is, the net is laid first, and then the anchor net 3 is applied to the side. No specific limitations are made here.

[0044] In summary, the sidewall auxiliary netting device 2 and the integrated excavation and anchoring machine 1 provided in the embodiments of the present invention have the following beneficial effects, including: The side-mounted auxiliary netting device 2 uses a first driving component 22 to simultaneously raise or lower the first lifting frame 23 and the second lifting frame 24, which helps improve the lifting efficiency of the anchor net 3, greatly improves the laying efficiency of the anchor net 3, reduces the labor intensity of operators, improves work efficiency, and promotes automated production. At the same time, the anchor net 3 has a large travel distance, achieving large-stroke movement (e.g., over 3000mm) in a small space, with a compact structure, reducing the device's size and space occupation. In this embodiment, the push rod, telescopic cylinder, and sliding mechanism share a common hydraulic power system and common control components, resulting in high collaborative work efficiency, a compact structure, and reduced overall size.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; any modifications, equivalent substitutions, improvements, etc., should be included within the protection scope of the present invention.
