Description

Technical Field

[0001] The present application relates to the technical field of drilling devices, and in particular to a drilling device for tunnel construction. Background Art

[0002] The structure of the tunnel consists of two parts: the main building and the ancillary equipment. The main building consists of the tunnel body and the tunnel portal, and the ancillary equipment includes the car shelter, fire-fighting facilities, emergency communications and drainage facilities. Long tunnels also have special ventilation and lighting equipment.

[0003] The patent with publication number CN114458153A discloses a drilling device for tunnel construction, which relates to the field of tunnel construction, and includes a drill bit, and also includes: a transmission rod, wherein the transmission rod is connected to the drill bit through a rotating rod arranged at one end, and can drive the drill bit to rotate so as to drill holes in the inner wall of the tunnel; a rotating sleeve, wherein a movable block is arranged at one end of the rotating rod away from the drill bit, and the rotating sleeve is fixedly installed on the side wall of the transmission rod, and is used to drive the movable block to move up and down and rotate; a driving mechanism, which is connected to the transmission rod; a limiting mechanism, which can control the drilling depth of the drill bit by limiting the stroke of the movable block; an reaming mechanism, wherein the transmission rod drives the reaming mechanism to rotate so as to expand the diameter of the deep hole drilled by the drill bit; the drilling device for tunnel construction controls the drilling depth of the drill bit through the limiting mechanism, and drives the drill bit to rotate through a motor so as to drill and reame holes in the inner wall of the tunnel, without the need for secondary reaming, thereby improving work efficiency.

[0004] In the process of implementing the above application, the inventors found that there are at least the following problems in the technology: the above drilling device is only suitable for conventional tunnel ground drilling. When drilling operations are required on the walls or ground of a tunnel with a very small section, the above drilling structure cannot complete the construction, resulting in reduced construction efficiency. Utility Model Content

[0005] In order to improve the efficiency of drilling construction, the present application provides a drilling device for tunnel construction.

[0006] The present application provides a tunnel construction drilling device that adopts the following technical solution:

[0007] A drilling device for tunnel construction comprises a drill body, a transport frame is detachably connected to the drill body, a mounting block is provided on the transport frame, and a mounting groove is provided on the mounting block, and the end of the drill body is passed through the mounting groove and is detachably connected to the mounting groove.

[0008] By adopting the above technical solution, the drill body can be assembled with the transport frame for transportation or drilling construction. When encountering a smaller tunnel, the drill body can also be disassembled and used alone, reducing the possibility that the transport frame is not easy to use in some smaller tunnels, and improving the work efficiency of the drilling process.

[0009] Optionally, two transport plates are fixed on the transport rack, both of which are arc-shaped and have a certain gap between them.

[0010] By adopting the above technical solution, both transport plates are arc-shaped and there is a certain gap between the two transport plates. The gap here facilitates the rotation process of the drill body. The drill body rotates along the arc-shaped transport plate, thereby facilitating the adjustment of the angle of the drill body.

[0011] Optionally, a positioning ring is rotatably connected to the top of the transport frame, and the positioning ring is placed at the end of the transport plate, wherein one of the side walls of the transport plate is slidably connected to a first positioning rod, and the first positioning rod abuts against the other side wall of the transport plate.

[0012] By adopting the above technical solution, the positioning ring cooperates with the first positioning rod to form a cavity, which limits the drill bit body and reduces the possibility of the drill bit body rotating autonomously. At the same time, by controlling the position of the first positioning rod, the drill bit body can be set horizontally or the drill bit body can be rotated.

[0013] Optionally, a rotation groove is provided on the transport frame, and the width of the rotation groove is the same as the width of the gap between the two transport plates. A second positioning rod is slidably connected to the inner side wall of the rotation groove, and the positioning rod extends to the outside of the transport frame.

[0014] By adopting the above technical solution, the inner side wall of the rotating groove is slidably connected with a second positioning rod. When the drill body is rotated to a vertical setting, the second positioning rod plays a limiting role on the drill body.

[0015] Optionally, a moving wheel is rotatably provided at the bottom of the transport rack to facilitate the movement of the transport rack, and a stop plate is rotatably provided on the side wall of the transport rack, and an end of the stop plate is in contact with the ground.

[0016] By adopting the above technical solution, the end of the stop plate is in contact with the ground. During the drilling construction process, since the end of the stop plate is in contact with the ground, it can effectively prevent the transport frame from moving in the opposite direction of the drilling direction, thereby facilitating the drilling construction process.

[0017] Optionally, an assembly groove is provided on the top of the mounting block, and the assembly groove is connected to the mounting groove, a closing cover is slidably provided in the assembly groove, a snap-in block is slidably provided on the side wall of the closing cover, and a snap-in groove for passing the snap-in block is provided on the inner side wall of the assembly groove.

[0018] By adopting the above technical solution, the closing cover can be connected to the mounting block by inserting the clamping block into the clamping groove, thereby reducing the possibility of the drill body being separated from the mounting block.

[0019] Optionally, a push block is slidably connected to the side wall of the mounting block, one end of the push block extends to the outside of the mounting block, and the other end extends into the clamping groove.

[0020] By adopting the above technical solution, one end of the pushing block extends to the outside of the mounting block, and the other end extends into the clamping groove. Therefore, the clamping block can be driven to move by pushing the pushing block, which facilitates the separation of the closing cover from the mounting block, thereby facilitating the disassembly of the drill body.

[0021] Optionally, the width of the mounting block is greater than the width of the gap between the two transport plates.

[0022] By adopting the above technical solution, the width of the installation block is greater than the width of the gap between the two transport plates, so during the rotation of the installation block, the installation block will not rotate into the gap between the two transport plates.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Assemble the drill body and the transport frame for transportation or drilling construction. When encountering a smaller tunnel, the drill body can also be disassembled and used alone, which reduces the possibility that the transport frame is not easy to use in some smaller tunnels and improves the work efficiency of the drilling process;

[0025] 2. Both transport plates are arc-shaped and there is a certain gap between the two transport plates. The gap here facilitates the rotation process of the drill body. The drill body rotates along the arc-shaped transport plate, thereby facilitating the adjustment of the angle of the drill body. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application embodiment discloses a drilling device for tunnel construction. Figure 1 , Figure 2 and Figure 3 The drilling device for tunnel construction includes a drill body 1, which is used to drill holes in the walls of the tunnel. A transport frame 2 is detachably connected to the drill body 1, which supports the drill body 1. At the same time, the transport frame 2 is convenient for driving the drill body 1 to move, which is convenient for the drilling process. A mounting block 3 is arranged on the transport frame 2 through a rotating shaft, and a mounting groove 4 is provided on the mounting block 3. The end of the drill body 1 can be inserted into the mounting groove 4 and detachably connected to the mounting groove 4. The drill body 1 can be driven to rotate by driving the mounting block 3 to rotate, which is convenient for the drilling process and the disassembly process of the drill body 1. When the tunnel is small and the transport frame 2 is not easy to use, the drill body 1 can be disassembled and used alone to work, which is convenient for the construction process.

[0033] Reference Figure 1 , Figure 2 and Figure 3 Two transport plates 5 are fixed to the transport frame 2 by bolts. The two transport plates 5 are both arranged in an arc shape, and there is a certain interval between the two transport plates 5. The width of the mounting block 3 is greater than the width of the gap between the two transport plates 5, which is convenient for the rotation process of the drill body 1. The interval between the two transport plates 5 is convenient for the movement of the drill body 1. A rotation groove 8 is opened on the transport frame 2, and the rotation groove 8 passes through the top of the transport frame 2 in the vertical direction. The width of the rotation groove 8 is the same as the width of the gap between the two transport plates 5. The mounting block 3 will not rotate into the rotation groove 8, and the end of the transport plate 5 abuts against the end face of the transport frame 2, so that the rotation groove 8 is connected with the gap between the two transport plates 5. The mounting block 3 can drive the drill body 1 to rotate, so that the drill body 1 is set horizontally or toward the bottom of the vertical direction, which is convenient for construction on the ground or wall.

[0034] Reference Figure 1 , Figure 2 and Figure 3The top of the transport frame 2 is rotatably connected with a positioning ring 6 by a rotating shaft, and the positioning ring 6 is positioned by bolt fixing, which reduces the possibility of rotation of the positioning ring 6. At the same time, the positioning ring 6 plays a limiting role on the drill bit body 1, wherein a first positioning hole is opened on the side wall of one of the transport plates 5, and a first positioning rod 7 is penetrated in the first positioning hole, and the first positioning rod 7 is slidably arranged in the first positioning hole, one end of the first positioning rod 7 abuts against the side wall of the other transport plate 5, and the other end extends to the outside of the transport frame 2, and a first spring is arranged in the first positioning hole, one end of the first spring is bonded to the side wall of the first positioning rod 7, and the other end is bonded to the inner side wall of the first positioning hole, and the first spring is used to push the first positioning rod 7 to abut against the side wall of the transport plate 5. The first positioning rod 7 cooperates with the positioning ring 6 to limit the drill bit body 1, so that the drill bit body 1 can be kept in a horizontally set state. When the drill bit body 1 needs to be transferred to the gap between the two transport plates 5, it only needs to pull the first positioning rod 7. After pulling, under the action of the first spring, the first positioning rod 7 is reset.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The second spring is used to drive the second positioning rod 9 to move so that the second positioning rod 9 abuts against the inner wall of the rotating groove 8, and the second positioning rod 9 plays a limiting role on the drill bit body 1. When the drill bit body 1 is horizontally arranged, the second positioning rod 9 supports the drill bit body 1. When the drill bit body 1 is vertically arranged, the second positioning rod 9 plays a limiting role on the drill bit body 1, which reduces the possibility of the drill bit body 1 shaking too much.

[0036] Reference Figure 1 The bottom of the transport frame 2 is connected to a moving wheel 10 through a rotating shaft. The moving wheel 10 facilitates the movement of the transport frame 2. At the same time, a stop plate 11 is provided on the side wall of the transport frame 2 through a rotating shaft. The stop plate 11 is placed away from the direction of the drill bit set on the drill body 1. The end of the stop plate 11 contacts the ground. During the drilling construction, the stop plate 11 has the possibility of preventing the moving part from moving in the opposite direction, thereby enhancing the stability of the construction process.

[0037] Reference Figure 1 , Figure 2 and Figure 3The top of the mounting block 3 is provided with an assembly groove 12, and the assembly groove 12 penetrates the top of the mounting block 3, and the mounting groove 4 is connected with the assembly groove 12. A closing cover 13 is passed through the assembly groove 12, and the closing cover 13 is slidably connected to the inner side wall of the assembly groove 12. The closing cover 13 and the mounting block 3 are detachably connected, so as to facilitate the installation and disassembly of the drill body 1. A clamping hole is provided on the side wall of the closing cover 13, and a clamping block 14 is passed through the clamping hole and the clamping block 14 is slidably connected to the inner side wall of the clamping hole. A clamping spring for pushing the clamping block 14 away from the clamping hole is provided in the clamping hole. The assembly groove 12 is provided with a closing cover 13, and the closing cover 13 is detachably connected to the inner side wall of the clamping hole. A snap-fitting groove 15 is provided on the side wall, and the snap-fitting groove 15 is used to penetrate the snap-fitting block 14, so as to facilitate the connection between the closing cover 13 and the mounting block 3. A pushing hole is provided on the side wall of the mounting block, and the pushing hole is communicated with the snap-fitting groove 15. A pushing block 16 is penetrated in the pushing hole and the pushing block 16 can slide in the pushing hole. One end of the pushing block 16 extends to the outside of the mounting block 3, and the other end extends to the inside of the snap-fitting groove 15. Pressing the pushing block 16 can make the pushing block 16 drive the snap-fitting block 14 to move, so as to facilitate the separation of the closing cover 13 from the mounting block 3. At the same time, a snap-fitting guide surface is provided on the snap-fitting block 14 to facilitate the movement of the snap-fitting block 14.

[0038] The implementation principle of a drilling device for tunnel construction in an embodiment of the present application is as follows: the drill body 1 is assembled with the transport frame 2 for transportation or drilling construction. When encountering a smaller tunnel, the drill body 1 can also be disassembled and used alone, which reduces the possibility that the transport frame 2 is not easy to use in some smaller tunnels and improves the work efficiency of the drilling process. The two transport plates 5 are both arc-shaped and there is a certain gap between the two transport plates 5. The gap here facilitates the rotation process of the drill body 1. The drill body 1 rotates along the arc-shaped transport plate 5, thereby facilitating the adjustment of the angle of the drill body 1.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
