DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0035] Embodiment one:

[0036] Please refer to Figures 1-7 , a tunnel punching device, comprising:

[0037] ​​The receiving plate 1 is provided with a drilling machine 2 and a driving mechanism 3 for driving the drilling machine 2 to move, and the drilling machine 2 is provided with a drill bit 4;

[0038] A slag receiving cylinder 5 and a water storage tank 6 are arranged on the receiving plate 1, and the drill bit 4 is movably arranged through the bottom wall of the slag receiving cylinder 5;

[0039] A ring pipe 7 is arranged on the periphery of the slag receiving cylinder 5, and a plurality of nozzles 8 are communicated on the ring pipe 7;

[0040] A conversion cylinder 10 is arranged on the water storage tank 6, and the conversion cylinder 10 is connected with a linkage mechanism 9 for guiding the water in the water storage tank 6 into the conversion cylinder 10 under the cooperation of the driving mechanism 3, and then the water is sprayed out through the nozzles 8 on the ring pipe 7.

[0041] In use, the receiving plate 1 of the present application is installed on a mechanical device (such as a mechanical arm), and then the receiving plate 1 is moved to a position with a hole in the tunnel, and the end of the slag receiving cylinder 5 is close to the inner wall of the tunnel, and then the drilling machine 2 is started to drive the drill bit 4 to rotate, and at the same time the driving mechanism 3 drives the drilling machine 2 and the drill bit 4 to move together, so that the drilling operation can be realized through the drill bit 4.

[0042] When drilling the inner wall of the tunnel, since the slag receiving cylinder 5 is close to the inner wall of the tunnel and the drill bit 4 is located inside the slag receiving cylinder 5, most of the debris generated by drilling can fall into the slag receiving cylinder 5, so that the debris can be collected, the danger of falling objects can be prevented, the danger to the workers can be reduced, the safety protection effect can be improved, and the safe and civilized construction in the tunnel can be better ensured.

[0043] There is a gap between the slag receiving cylinder 5 and the inner wall of the tunnel, which facilitates the observation of the drilling condition and reduces the visual obstruction, and since the inner wall of the tunnel is arc-shaped, there is always a gap between the slag receiving cylinder 5 and the inner wall of the tunnel. During the drilling process, under the cooperation of the driving mechanism 3, the linkage mechanism 9 guides the water in the water storage tank 6 into the conversion cylinder 10, and then the water is sprayed out through the nozzles 8 on the ring pipe 7. The sprayed water can perform dust suppression treatment on the surrounding of the drilling position. The water and the dust particles in the air combine and settle to the ground, reducing the concentration of suspended particulate matter in the air and preventing fine particulate matter from flying up to form dust. The construction environment and the health of the workers are better protected; the obstruction of dust to the vision is also reduced, which facilitates the workers to timely process and adjust, greatly improving the quality and effect of drilling.

[0044] Moreover, when the slag receiving cylinder 5 is removed after drilling is completed, dust will also be generated in the slag receiving cylinder 5, which can also be treated by the nozzles 8 on the ring pipe 7 to effectively reduce the dust, better protect the environment and the health of the personnel.

[0045] Preferably, please refer to Figure 1 , Figure 3 and Figures 5-6The water inlet pipe 11 is communicated with the water storage tank 6, and the end of the water outlet pipe 12 is connected with the hose 13, and the other end of the hose 13 is communicated with the ring pipe 7.

[0046] Specifically, under the action of the linkage mechanism 9, the water in the water storage tank 6 enters the conversion cylinder 10 through the water inlet pipe 11, and then enters the ring pipe 7 through the water outlet pipe 12 and the hose 13, and is finally sprayed out from the nozzle 8 of the ring pipe 7.

[0047] Preferably, referring to Figures 3-6 The valve 14 is hinged at the position corresponding to the water inlet pipe 11 in the conversion cylinder 10, the valve 15 is hinged on the inner wall of the position where the water outlet pipe 12 is connected with the conversion cylinder 10, and the piston plate 16 is slidingly connected with the inner wall of the conversion cylinder 10.

[0048] In this way, the linkage mechanism 9 drives the piston plate 16 to move back and forth, so that Figures 5-6 For example, when the piston plate 16 moves to the left, the valve 15 is closed under the action of negative pressure, that is, the water outlet pipe 12 is closed, and the valve 14 is opened, that is, the water inlet pipe 11 is communicated with the conversion cylinder 10, and in the process of the piston plate 16 moving to the left, the negative pressure drives the water in the water storage tank 6 to enter the conversion cylinder 10, and is located at the right side of the piston plate 16, that is, as shown in the figure. Figure 5 When the piston plate 16 moves to the right, the valve 14 is closed under the action of negative pressure, that is, the water inlet pipe 11 is closed, and the valve 15 is opened, that is, the water outlet pipe 12 is communicated with the conversion cylinder 10, and in the process of the piston plate 16 moving to the right, the water in the conversion cylinder 10 is pushed into the water outlet pipe 12, and finally the water enters the ring pipe 7 and is sprayed out through the nozzle 8. The design is ingenious and simple, and the use effect is good, that is, the piston plate 16 moves back and forth while the nozzle 8 sprays water to reduce dust.

[0049] Preferably, referring to Figures 1-3 The driving mechanism 3 comprises:

[0050] The vertical plate 31 and the driving part 32 are respectively arranged at the upper and lower ends of the receiving plate 1, the vertical plate 31 is rotatably connected with the lead screw 33, one end of the lead screw 33 is connected with the output end of the driving part 32, and the connecting seat 34 connected with the drilling machine 2 is threadedly connected with the lead screw 33;

[0051] The vertical plate 31 is provided with the sliding rail 35, and the connecting seat 34 is provided with the sliding block 36 slidingly connected with the sliding rail 35.

[0052] Specifically, the driving member 32 in the application can adopt a servo motor. After the driving member 32 is started, the screw rod 33 will be driven to rotate. Since the slide rail 35 and the sliding block 36 limit the rotation of the connecting seat 34, the rotation of the screw rod 33 will drive the connecting seat 34 to move along the screw rod 33, so that the connecting seat 34 drives the drilling machine 2 to move and punch. The movement of the connecting seat 34 drives the sliding block 36 to slide along the slide rail 35, and the stability of the drilling machine 2 during the movement and the punching process can be improved, and the use effect is good.

[0053] Preferably, referring to Figures 3-6 , the linkage mechanism 9 comprises:

[0054] The disc 91 is connected with the screw rod 33, the disc 91 is rotationally connected with the connecting rod 92, the end of the connecting rod 92 is rotationally connected with the push-pull rod 93, and the other end of the push-pull rod 93 is movably penetrated into the conversion cylinder 10 and connected with the piston plate 16.

[0055] In this way, when the screw rod 33 rotates, the connecting rod 92 will be driven to rotate, and the push-pull rod 93 will be driven to reciprocate left and right, that is, the push-pull rod 93 will drive the piston plate 16 to reciprocate left and right, so that the repeated water inlet and outlet in the conversion cylinder 10 can be realized, thereby achieving the dust reduction effect by spraying water during the punching process.

[0056] Embodiment two:

[0057] On the basis of embodiment one, referring to Figure 1 , Figure 3 and Figure 7 , the receiving plate 1 is provided with a plurality of support plates 17, the support plates 17 are provided with retractable connecting plates 18, and the other ends of the connecting plates 18 are connected with the slag receiving cylinder 5.

[0058] In this way, when the receiving plate 1 drives the slag receiving cylinder 5 to move, after the slag receiving cylinder 5 contacts the inner wall of the tunnel, the inner wall of the tunnel will extrude the slag receiving cylinder 5, and the slag receiving cylinder 5 will cause the connecting plate 18 to be compressed, thereby playing a buffering role, preventing the slag receiving cylinder 5 from being damaged due to hard contact with the inner wall of the tunnel. In some special cases, the slag receiving cylinder 5 can also be in closer contact with the inner wall of the tunnel, thereby improving the collection effect of the collected slag.

[0059] Preferably, referring to Figure 7 , the support plate 17 is provided with an inner hidden cavity 19 connected with the connecting plate 18 in sliding mode, and the inner end of the connecting plate 18 and the bottom wall of the inner hidden cavity 19 are provided with an elastic member 20. The elastic member 20 in the application can adopt a spring. When the slag receiving cylinder 5 is compressed to drive the connecting plate 18 to be compressed, the connecting plate 18 will move towards the inner hidden cavity 19 and compress the elastic member 20; after the slag receiving cylinder 5 is no longer compressed, the elastic member 20 will drive the connecting plate 18 and the slag receiving cylinder 5 to return to the initial position through the elastic force.
