Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel over-break and under-break control equipment, and provides an integrated contour excavation and filling device for tunnel over-break and under-break control. Background Art

[0002] Traditional full-face tunnel excavation relies primarily on drill-and-blast methods, typically smooth blasting and pre-splitting blasting. Due to changes in rock strata, geological conditions, and the development of surrounding rock fissures during tunnel excavation, deviations between the actual excavation contour and the designed excavation contour occur. These issues not only directly impact construction progress, safety, and quality, but also increase excavation costs. However, due to insufficient attention or inappropriate methods, overexcavation can inadvertently increase project costs during construction, thereby reducing expected profits.

[0003] Existing overbreak and underbreak control devices include a rotary auger, a base mounted on the ground, a lifting platform mounted on the base, a lifting assembly positioned between the lifting platform and the base for raising and lowering the lifting platform, an adjustment block slidably connected to the lifting platform, and a power assembly positioned between the adjustment block and the lifting platform for moving the adjustment block toward or away from the wall. However, due to limited tunnel space, this control device cannot achieve the desired excavation profile in one step, requiring the vehicle to be moved, which increases the workload. Furthermore, the buffer material filling after excavation requires manual work, increasing labor costs. Furthermore, the infrared light needs to be projected separately, which also increases time costs. Utility Model Content

[0004] In view of this, in order to solve the problems existing in the background technology, the utility model proposes an integrated device for contour excavation and filling for tunnel over- and under-control, which has a simple structure and is easy to use.

[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions:

[0006] The utility model provides an integrated device for contour excavation and filling for tunnel over-excavation and under-excavation control, comprising a base plate, a lifting plate provided on the base plate via a lifting assembly, a transverse plate provided on the lifting plate via a transverse assembly, a drilling assembly provided on the transverse plate via a drilling adjustment rod, and a filling assembly provided via a filling adjustment rod; the drilling assembly consists of a protective plate, a rotating motor, and an auger, the protective plate being connected to the drilling adjustment rod, the rotating motor being arranged on the protective plate via a sliding assembly for driving the auger; the filling assembly consists of a filling box and an inserting plate, the filling box being connected to the filling adjustment rod, a rotating shaft being provided in the middle of the filling box, and the inserting plate being curled in the filling box via the rotating shaft. By adopting the above scheme, the integrated device can effectively improve the efficiency of tunnel construction by integrating excavation and filling functions, reduce the occurrence of over-excavation and under-excavation, reduce construction costs, and help improve the economic benefits of the project.

[0007] Optionally, the bottom surface of the base plate is provided with rollers for movement. These rollers can effectively reduce friction with the ground and improve the flexibility and convenience of movement.

[0008] Optionally, four lifting assemblies can be configured, with each set consisting of a lifting motor and a lifting screw. The lifting motor is mounted on the base plate and drives the lifting screw. The lifting plate is located above the base plate and is connected to the lifting screw. This design of four lifting assemblies ensures balanced vertical movement of the lifting plate, avoiding operational instability caused by uneven heights. The configuration of multiple lifting assemblies enhances the overall stability of the device and reduces potential tilting or shaking during operation. The lifting height can also be quickly adjusted according to actual construction needs, improving construction efficiency.

[0009] Optionally, vertical baffles are provided on both the front and rear sides of the lifting plate; two sets of transverse assemblies are provided, each consisting of a transverse motor and a transverse screw. The transverse motor is provided on the front vertical baffle of the lifting plate to drive the transverse screw; the transverse plate is located between the front and rear vertical baffles of the lifting plate, and the transverse plate is connected to the transverse screw. In this way, the design of the two sets of transverse assemblies allows the transverse plate to be flexibly adjusted in the front-to-back direction to adapt to the conditions of the tunnel excavation surface. The synchronous drive of the two sets of transverse motors ensures the smooth movement of the transverse plate, avoiding unstable operation due to uneven movement. The design of the vertical baffles enhances the stability of the transverse plate 7, ensuring that it will not shake during operation, thereby improving construction safety.

[0010] Optionally, rotary joints are provided at the respective connections between the transverse plate and the drilling adjustment rod, the transverse plate and the filling adjustment rod, the drilling adjustment rod and the protective plate, and the filling adjustment rod and the filling box. Both the drilling adjustment rod and the filling adjustment rod adopt a two-link structure, and a rotary joint is also provided at the connection between the two links. In this way, the design of the rotary joint enables the device to perform complex operations in narrow tunnel environments, especially when it is necessary to adjust the drilling and filling angles, and it can effectively cope with various geological conditions. Furthermore, through the rotary joint, drilling and filling operations can be completed quickly and accurately, reducing the time wasted due to manual angle adjustment and improving construction efficiency overall. The two-link structure design enhances the stability of the adjustment rod, making it less likely to deviate during operation, thereby ensuring the accuracy of excavation and filling.

[0011] Optionally, the sliding assembly consists of a rectangular rack, a slider, and a drive motor. The protective plate is provided with a guide slot for mounting the rectangular rack. The slider engages with the rectangular rack, and the drive motor is mounted on the slider to drive the slider. In this way, through the combination of the rotary motor and the sliding assembly, the drilling assembly can quickly and accurately drill holes in the tunnel excavation face, improving construction efficiency. The sliding assembly's design also allows for lateral adjustment of the drilling assembly to accommodate varying drilling requirements.

[0012] Optionally, the filling assembly further comprises a power motor, a cylindrical cam, and a cutter. A support for mounting the power motor is provided within the filling box. The output shaft of the power motor is provided with a cylindrical cam. The outer wall of the cylindrical cam is provided with radially distributed, continuously undulating, inclined wave grooves. The cutter is slidably mounted on the filling box and slidably connected to the inclined wave grooves via a short shaft to cut the insert plate. In this manner, the combination of the power motor, the cylindrical cam, and the cutter can achieve the desired effect of cutting the filling material.

[0013] Optionally, the filling assembly further includes a rotating friction wheel and a guide plate. The guide plate is used to guide the insert plate out of the filling box. The guide plate is spaced apart from the cutter at one end. A rotating friction wheel is positioned on the filling box on the opposite side of the insert plate from the guide plate to provide power to the insert plate. The rotating friction wheel design allows the insert plate to be quickly pushed out of the filling box, improving filling efficiency.

[0014] The lifting platform can be optionally equipped with a telescopic pole with an infrared laser light at its top. This allows the laser to assist the auger in accurate drilling, helping to monitor and adjust drilling accuracy in real time, reducing over- and under-break caused by deviations. The height adjustment of the pole allows adaptation to different excavation surfaces, ensuring the accuracy of the laser line.

[0015] Optionally, a control panel with a data processor is installed on the lifting platform. The data processor is electrically connected to the lifting assembly, traverse assembly, drilling assembly, slide assembly, filling assembly, and infrared laser light. This allows the operator to input a preset tunnel excavation contour line graphic into the data processor and, through the control panel, set the position of the infrared laser light on the tunnel face. The data processor is responsible for coordinating the work of each component, monitoring their status in real time and automatically adjusting them based on the input contour line graphic, ensuring efficient system coordination and enhancing the intelligence level of the entire device, thereby ensuring the accuracy and efficiency of the drilling operation.

[0016] The beneficial effects of the present invention are as follows: the integrated device for contour excavation and filling for tunnel over- and under-control mentioned in the present invention has the following advantages:

[0017] 1. Integrated Operation: Integrating excavation and filling functions into the same device avoids the time delays associated with separate construction methods used in traditional methods. This integrated design streamlines the construction process and significantly shortens the project cycle.

[0018] 2. Automated operation: Through motor drive and data processing system, the device can realize automated operation, reduce the need for human intervention, and thus improve work efficiency.

[0019] 3. Precision Drilling: Through the auxiliary guidance of infrared laser lights and the intelligent control of data processors, the device can achieve high-precision drilling position adjustment. This reduces over-excavation and under-excavation caused by human judgment errors and ensures that the excavation profile conforms to the design requirements.

[0020] In general, this integrated contour excavation and filling device for tunnel over-excavation and under-excavation control provides important technical support and guarantee for modern tunnel construction by improving construction accuracy, enhancing construction efficiency, improving safety, reducing construction costs, having strong adaptability, and improving engineering economic benefits.

[0029] The present invention is further described below in conjunction with specific embodiments. The accompanying drawings are for illustrative purposes only and are schematic, not actual, representations. They should not be construed as limiting this patent. To better illustrate the embodiments of the present invention, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted from the drawings.

[0030] like Figure 1-5As shown, the integrated device for contour excavation and filling for tunnel over- and under-control mentioned in the present invention includes a base plate 1, which is the basic component of the device and has a stable supporting function. Four rollers 2 for movement are provided around the bottom surface of the base plate 1 to facilitate the movement of the device in the tunnel. A lifting plate 5 is provided on the base plate 1 via a lifting assembly, a transverse plate 7 is provided on the lifting plate 5 via a transverse assembly, a drilling assembly is provided on the transverse plate 7 via a drilling adjustment rod 11, and a filling assembly is provided via a filling adjustment rod 19. In this way, by providing the lifting plate and the transverse plate, the height and horizontal direction can be adjusted at any time according to construction needs, so that the drilling assembly can perform drilling operations during the tunnel excavation process to facilitate subsequent blasting, and the filling assembly can perform filling operations after excavation, which can effectively fill the buffer material to the required position, thereby adapting to the curvature and depth of the tunnel excavation contour line and the requirements of the plug plate to adapt to the filling borehole.

[0031] Specifically, the lifting components are set to four sets to ensure the stability and uniformity of the lifting plate 5, and each set is composed of a lifting motor 3 and a lifting screw rod 4. The lifting motor 3 is arranged on the base plate 1 and serves as a driving device to provide lifting power for driving the lifting screw rod 4; the lifting plate 5 is located above the base plate 1, and the lifting plate 5 is connected to the lifting screw rod 4, so that the four sets of lifting motors 3 and the lifting screw rods 4 synchronously drive the lifting plate 5 to move up and down, so that the lifting plate 5 can adjust the height smoothly and synchronously during the lifting process.

[0032] Vertical baffles 6 are provided on the front and rear sides of the lifting plate 5. As the main load-bearing components of the transverse movement assembly, the transverse movement assembly is provided in two sets to realize the flexible movement of the transverse movement plate 7, and a single set is composed of a transverse movement motor 8 and a transverse movement screw rod 9. The transverse movement motor 8 is provided on the front vertical baffle 6 of the lifting plate 5. As a driving device, it provides power for transverse movement and is used to drive the transverse movement screw rod 9; the transverse movement plate 7 is located between the front and rear vertical baffles 6 of the lifting plate 5, and the transverse movement plate 7 is connected to the transverse movement screw rod 9, so that the two sets of transverse movement motors 8 and the transverse movement screw rod 9 synchronously drive the transverse movement plate 7 to move forward and backward, so that the device can be adjusted to a suitable position on the tunnel excavation surface.

[0033] Revolving joints 10 are installed at the connections between the traversing plate 7 and the drilling adjustment rod 11, the traversing plate 7 and the tamping adjustment rod 19, the drilling adjustment rod 11 and the protective plate 12, and the tamping adjustment rod 19 and the filling box 20. Both the drilling adjustment rod 11 and the tamping adjustment rod 19 utilize a two-link structure, which enhances the rod's stability and torsional resistance, ensuring accurate angles and positions during drilling and tamping. Revolving joints 10 are also installed at the connections between the two links. Revolving joints allow connected components to rotate about a single axis, providing a flexible range of motion. This design allows each component to adapt to different operational requirements during operation, enhancing the flexibility and adaptability of the overall device. Revolving joints are one of the most common joint types in industrial robots and are a conventional device. Revolving joints typically consist of a motor and a reducer. The motor provides power, while the reducer reduces the motor's output speed and increases its output torque. By controlling the motor's rotation direction and speed, revolving joints enable precise control, making drilling and tamping operations more flexible and efficient.

[0034] The drilling assembly consists of a protective plate 12, a rotating motor 17, and an auger 18. The protective plate 12 is connected to the drilling adjustment rod 11 to provide protection and support for the drilling operation. That is, the main function of the protective plate 12 is to protect the internal components and reduce the impact of dust and gravel that may be generated during tunnel excavation on the equipment. It also provides fixed support for the rotating motor and the auger. The rotating motor 17 is set on the protective plate 12 through a sliding assembly to drive the auger 18, thereby realizing the operation of drilling holes on the tunnel excavation surface; the sliding assembly consists of a rectangular rack 14, a slider 15, and a drive motor 16, which provides a drilling The component has the lateral movement ability, and the protective plate 12 is provided with at least two guide long holes 13 for installing the rectangular rack 14. The slider 15 is engaged with the rectangular rack to ensure that the slider 15 can move smoothly on the protective plate 12, and the drive motor 16 is set on the slider 15 and is used to drive the lateral movement of the slider 15, and the rotary motor 17 is also set on the slider 15 to drive the auger 18 to perform contour drilling on the tunnel excavation surface while following the movement of the slider 15, that is, the auger 18 can penetrate the drill bit into the tunnel excavation surface while rotating, and drill according to the predetermined contour line.

[0035] The filling assembly consists of a filling box 20 and an inserting plate 21. The filling box 20 is connected to the filling adjusting rod 19. The filling box 20 serves as a storage and conveying device for filling materials. A rotating shaft 22 is provided in the middle thereof for supporting the curling and unfolding of the inserting plate 21, that is, the inserting plate 21 is curled in the filling box 20 by the rotating shaft 22, and the inserting plate 21 can be flexibly inserted or output through the rotation of the rotating shaft 22 to meet the filling needs. The inserting plate 21 is made of flexible buffer material and has a shock-absorbing or shock-absorbing effect. The inserting plate 21 can be inserted according to the contour line of the auger drill to realize the integration of drilling and filling, thereby reducing the over-excavation and under-excavation caused by the explosion shock wave; the filling assembly also includes a power motor 24, a cylindrical cam 25 and a cutter 27. A support 23 for mounting the power motor 24 is provided in the filling box 20, and a cylindrical cam 25 is provided on the output shaft of the power motor 24. The outer wall of the cylindrical cam 25 The cutter 27 is slidably mounted on the filling box 20 and slidably connected to the inclined groove 26 by a short shaft, so as to cut the plug plate 21. That is, the design of the inclined groove enables the cutter 27 to make a vertical reciprocating motion up and down, thereby effectively cutting the plug plate 21 and ensuring the disconnection of the filling material after transportation. The filling assembly also includes a rotating friction wheel 28 and a guide plate 29. The guide plate 29 is used to guide the plug plate 21 out of the filling box 20, and the guide plate 29 is spaced from the end close to the cutter 27 to avoid interference during the cutting process of the plug plate 21. A rotating friction wheel 28 for outputting power to the plug plate 21 is arranged on the filling box 20 on the opposite side of the plug plate 21 and the guide plate 29. That is, the rotating friction wheel 28 provides power to ensure that the plug plate 21 can be smoothly pushed out of the filling box 20, and the guide plate 29 ensures smooth transportation of the filling material.

[0036] In this embodiment, a vertical pole 30 is mounted on the lifting platform 5. An infrared laser light 31 is mounted at the top of the pole 30, which projects a laser indicator line. This laser light allows the auger 18 to adjust the drilling position along the guide slot 13 to match the tunnel excavation contour. This laser guidance facilitates real-time monitoring and adjustment of drilling accuracy, reducing over- and under-excavation caused by deviations. The pole 30 is telescopic, facilitating adjustment of the vertical height of the infrared laser light 31. A control panel 33 with a data processor 32 is provided on the front vertical baffle 6 of the lifting plate 5, which is convenient for the operator to control and monitor. The data processor 32 is responsible for receiving and processing control instructions from each component, and is respectively electrically connected to the lifting motor 3 of the lifting component, the transverse motor 8 of the transverse component, the rotating motor 17 of the drilling component, the driving motor 16 of the sliding component, the power motor 24 of the filling component and the motor of the rotating friction wheel 28, each rotating joint 10 and the infrared laser lamp 31 to input the preset tunnel excavation contour line graphic into the data processor 32, and operate on the control panel 33 to set the position of the infrared laser lamp 31 projected on the tunnel face to assist the auger drilling.

[0037] Specific steps:

[0038] S1. Clean the tunnel face, draw the tunnel overbreak and underbreak contour excavation lines on the tunnel face in advance, and move the integrated device for tunnel overbreak and underbreak control contour excavation and filling to the tunnel face via roller 2, so that it is set close to the wall surface;

[0039] S2, first start the lifting motor 3 and drive the lifting plate 5 up and down through the lifting screw rod 4 until it is adjusted to a suitable height position;

[0040] S3, restart the transverse motor 8 and drive the transverse plate 7 to move forward and backward through the transverse screw rod 9 until it is adjusted to the appropriate position;

[0041] S4. Input the preset tunnel contour line graphic into the data processor 32 and transmit it to the infrared laser light 31 via the data transmission line provided in the vertical pole 30. The infrared laser light 31 then projects the graphic onto the tunnel face, and the control panel 33 controls the position of the projection of the infrared laser light 31 until it coincides with the contour line on the wall.

[0042] S5. First, the drilling adjustment rod 11 is adjusted by starting the rotary joint 10 to make the drilling assembly reach a suitable position. Then, the motor 16 is driven on the protective plate 12 to automatically adjust the position of the slider 15 on the guide slot 13. That is, the inner side of the slider 15 is a gear ring and moves on the rectangular rack 14.

[0043] S6, starting the rotary motor 17, so that the auger 18 starts drilling on the specified contour line;

[0044] S7, then, start the rotary joint 10 on the filling adjustment rod 19, so that the filling assembly is aligned with the drilled hole of the auger 18 and fill the insert plate 21 in the drilled hole;

[0045] S8. After excavation is completed at the location targeted by the infrared projection and the blasting device is installed, the insert plate 21 limits the tunnel blasting range to within the designed tunnel excavation contour. When blasting within the designed tunnel excavation contour, the vibration waves from the blasting impact the insert plate 21, thereby reducing the possibility of over-excavation caused by the blasting device. This integrated infrared projection, contour excavation, and filling reduces labor costs and saves construction time.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
