Description

Technical Field

[0001] This invention belongs to the technical field of tunnel construction equipment, specifically relating to a roughening machine and its usage method. Background Technology

[0002] With the rapid development of railway tunnel construction, tunnel defects have gradually emerged. In the process of treating tunnel defects, it is necessary to roughen the tunnel surface, that is, to remove the hardened crust from the old concrete surface to create a rough surface, so that the new concrete surface has better adhesion to the old concrete surface. Roughening machines can be roughly divided into handheld, push-type, walk-behind (suspended), and machine-mounted types according to their working method.

[0003] Traditional shaving machines have the following problems during use; (1) During the use of the airborne chiseling machine, the chiseling angle adjustment range of the chiseling machine needs to be measured manually or judged by experience. The adjustment process is relatively complicated and cumbersome. At the same time, the chiseling machine cannot be automatically adjusted during use.

[0004] (2) It is difficult to cover the entire tunnel lining surface when using a handheld chisel, which consumes a lot of manpower. Summary of the Invention

[0005] This invention provides a shaving machine and its method of use, in order to at least solve some of the above-mentioned technical problems.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A shaving machine includes a mounting base, a pitch adjustment mechanism disposed on the mounting base, a telescopic adjustment mechanism slidably disposed within the pitch adjustment mechanism, an angle adjustment mechanism disposed on the telescopic adjustment mechanism, a rotating mechanism rotatably disposed on the angle adjustment mechanism, a connecting mechanism disposed on the rotating mechanism, and a shaving mechanism movably disposed on the connecting mechanism.

[0007] Furthermore, the connecting mechanism includes a connecting mounting plate disposed on the rotating mechanism, a universal joint with one end connected to the connecting mounting plate and the other end connected to the roughening mechanism, and a protective cover disposed on the connecting mounting plate.

[0008] Furthermore, the chiseling mechanism includes a buffer mounting plate movably mounted on the connecting mechanism, several buffer mechanisms mounted on the buffer mounting plate, a chiseling mounting plate mounted on the buffer mechanisms, and several chiseling devices mounted on the chiseling mounting plate.

[0009] Furthermore, the buffer mechanism includes clearance holes respectively opened on the buffer mounting plate and the roughened mounting plate, a stud slidably disposed between the two clearance holes, and a buffer spring fitted on the stud and with its two ends respectively abutting against the buffer mounting plate and the roughened mounting plate, and a limit nut provided on the stud.

[0010] Furthermore, the chiseling device includes support seats that are mirror-symmetrically disposed on the chiseling mounting plate, a chiseling head that is rotatably disposed between the two support seats, and a number of chiseling teeth disposed on the chiseling head.

[0011] Furthermore, the pitch adjustment mechanism includes a height connecting seat rotatably mounted on the mounting base, a floating arm mounted on the height connecting seat, and a hydraulic cylinder A with one end rotatably connected to the floating arm and the other end rotatably connected to the height connecting seat; the telescopic adjustment mechanism is slidably mounted inside the floating arm.

[0012] Furthermore, the telescopic adjustment mechanism includes a telescopic arm that is slidably disposed within the floating arm and connected to the angle adjustment mechanism, and a hydraulic cylinder C disposed within the floating arm and connected to the telescopic arm.

[0013] Furthermore, the angle adjustment mechanism includes an angle connecting seat mounted on the pitch adjustment mechanism, an adjustment seat rotatably mounted on the angle connecting seat, and a hydraulic cylinder B with one end rotatably connected to the adjustment seat and the other end rotatably connected to the angle connecting seat; a rotation mechanism is mounted on the adjustment seat.

[0014] Furthermore, the rotating mechanism includes a hydraulic motor and a rotary bearing mounted on the angle adjustment mechanism, and a transmission mechanism mounted on the outer ring of the rotary bearing and connected to the output end of the hydraulic motor; the connecting mechanism is mounted on the transmission mechanism. The transmission mechanism includes a drive gear located on the output end of the hydraulic motor and a driven gear located on the rotary bearing and meshing with the drive gear; the connecting mechanism is mounted on the driven gear by bolts.

[0015] A method of using a shaving machine includes the following steps: S1. When the mounting base is moved to the desired position, hydraulic cylinder A is activated. Hydraulic cylinder A drives the floating arm to swing up or down to adjust the angle of the floating arm. At the same time, hydraulic cylinder C is activated. Hydraulic cylinder C pushes the telescopic arm to slide in the floating arm, thereby adjusting the height of the chiseling device. S2. After the height of the floating arm is adjusted, start hydraulic cylinder B. Hydraulic cylinder B drives the adjusting seat to swing up or down. The adjusting seat drives the connecting mechanism and the chiseling mechanism to move synchronously through the rotating mechanism. S3. When the scabbing device comes into contact with the tunnel wall, it will squeeze the buffer mechanism. Since the scabbing device and the connecting mechanism are connected, the scabbing device will further fit into the tunnel wall. S4. Start the rotating mechanism. The rotating mechanism drives the chiseling mechanism to rotate synchronously through the connecting mechanism, thereby realizing the chiseling operation on the tunnel wall.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention has a simple structure, a scientific and reasonable design, and is easy to use.

[0017] 2. The present invention uses a pitch adjustment mechanism and an angle adjustment mechanism in combination to facilitate the adjustment of the position of the chiseling mechanism.

[0018] 3. The present invention, through the cooperation of the protective cover and the universal joint, can not only realize the transmission of power, but also limit the angle of the chiseling mounting plate, thereby facilitating the adjustment of the angle of the chiseling device.

[0035] Example 1. As... Figure 1-12 As shown, the present invention provides a shaving machine, including a mounting base 1, a pitch adjustment mechanism 2 disposed on the mounting base 1, an angle adjustment mechanism 3 disposed on the pitch adjustment mechanism 2, a rotating mechanism rotatably disposed on the angle adjustment mechanism 3, a connecting mechanism disposed on the rotating mechanism, and a shaving mechanism 4 movably disposed on the connecting mechanism.

[0036] The present invention uses a combination of a pitch adjustment mechanism, a telescopic adjustment mechanism and an angle adjustment mechanism to adjust the height and angle of the chiseling mechanism, thereby facilitating the chiseling operation of the chiseling mechanism under the drive of the transport vehicle.

[0037] The present invention uses the pitch adjustment mechanism 2 and the angle adjustment mechanism 3 in combination to facilitate the adjustment of the position of the chiseling mechanism 4.

[0038] When this invention is used, the pitch adjustment mechanism 2 is in operation. The pitch adjustment mechanism 2 drives the angle adjustment mechanism 3, the rotation mechanism, the connecting mechanism, and the chiseling mechanism 4 to move synchronously. Then, the angle adjustment mechanism 3 is activated, and the angle adjustment mechanism 3 drives the rotation mechanism, the connecting mechanism, and the chiseling mechanism 4 to move, thereby further adjusting the position of the chiseling mechanism 4. When the chiseling mechanism 4 comes into contact with the tunnel wall, the rotation mechanism drives the chiseling mechanism 4 to rotate through the connecting mechanism, thereby realizing the chiseling operation on the tunnel wall.

[0039] The mounting base 1 of the present invention is installed on a transport vehicle, such as a road-rail dual-purpose platform.

[0040] Example 2. (As shown) Figure 1-12 As shown, the present invention provides a shaving machine, including a mounting base 1, a pitch adjustment mechanism 2 disposed on the mounting base 1, an angle adjustment mechanism 3 disposed on the pitch adjustment mechanism 2, a rotating mechanism rotatably disposed on the angle adjustment mechanism 3, a connecting mechanism disposed on the rotating mechanism, and a shaving mechanism 4 movably disposed on the connecting mechanism.

[0041] The connecting mechanism includes a connecting mounting plate 5 mounted on the rotating mechanism, a universal joint 6 connected at one end to the connecting mounting plate 5 and at the other end to the roughening mechanism 4, and a protective cover 7 mounted on the connecting mounting plate 5.

[0042] This embodiment 2 provides a more detailed structure of the connecting mechanism based on embodiment 1. The connecting mechanism includes a connecting mounting plate 5 on the rotating mechanism, a universal joint 6 with one end connected to the connecting mounting plate 5 and the other end connected to the chiseling mechanism 4, and a protective cover 7 on the connecting mounting plate 5.

[0043] When the present invention is used, the connecting mounting plate 5 rotates synchronously with the rotating mechanism. The connecting mounting plate 5 drives the chiseling mechanism 4 to rotate synchronously through the universal joint 6, thereby driving the chiseling mechanism 4 to rotate, which facilitates the chiseling mechanism 4 to perform chiseling operations on the tunnel wall.

[0044] The protective cover 7 of the present invention can not only protect the universal joint 6 and improve the service life of the universal joint 6, but also limit the angle of the chiseling mechanism 4; the protective cover 7 is provided with a wear-resistant ring to reduce the wear of the protective cover 7, and the wear-resistant ring can extend the service life of the protective cover 7.

[0045] Example 3. (As shown) Figure 1-12 As shown, the present invention provides a shaving machine, including a mounting base 1, a pitch adjustment mechanism 2 disposed on the mounting base 1, an angle adjustment mechanism 3 disposed on the pitch adjustment mechanism 2, a rotating mechanism rotatably disposed on the angle adjustment mechanism 3, a connecting mechanism disposed on the rotating mechanism, and a shaving mechanism 4 movably disposed on the connecting mechanism.

[0046] The chiseling mechanism 4 includes a buffer mounting plate 8 movably mounted on the connecting mechanism, several buffer mechanisms mounted on the buffer mounting plate 8, a chiseling mounting plate 9 mounted on the buffer mechanisms, and several chiseling devices mounted on the chiseling mounting plate 9.

[0047] This embodiment 3 provides a more detailed structure of the chiseling mechanism 4 based on embodiment 1. The chiseling mechanism 4 includes a buffer mounting plate 8 movably mounted on the connecting mechanism, several buffer mechanisms mounted on the buffer mounting plate 8, a chiseling mounting plate 9 mounted on the buffer mechanisms, and several chiseling devices mounted on the chiseling mounting plate 9.

[0048] In this invention, the buffer mounting plate 8 is connected to the universal joint 6. The universal joint 6 can transmit the rotational force of the rotating mechanism to the buffer mounting plate 8, so that the buffer mounting plate 8 rotates synchronously. The buffer mounting plate 8 drives the roughening mounting plate 9 to rotate through the buffer mechanism. The roughening mounting plate 9 drives the roughening device to rotate, thereby realizing the roughening operation of the tunnel wall.

[0049] Because there is a certain gap between the protective cover 7 and the buffer mounting plate 8, the buffer mounting plate 8 can rotate after being connected to the universal joint 6, and the angle of the buffer mounting plate 8 can also be limited.

[0050] The present invention, through the cooperation of the protective cover 7 and the universal joint 6, can not only realize the transmission of power, but also limit the angle of the chisel mounting plate 9, thereby facilitating the adjustment of the angle of the chisel device.

[0051] The present invention has multiple buffering mechanisms that can buffer the vibration force during the chiseling process of the chiseling device.

[0052] Example 4. (As shown) Figure 1-12 As shown, the present invention provides a shaving machine, including a mounting base 1, a pitch adjustment mechanism 2 disposed on the mounting base 1, an angle adjustment mechanism 3 disposed on the pitch adjustment mechanism 2, a rotating mechanism rotatably disposed on the angle adjustment mechanism 3, a connecting mechanism disposed on the rotating mechanism, and a shaving mechanism 4 movably disposed on the connecting mechanism.

[0053] The chiseling mechanism 4 includes a buffer mounting plate 8 movably mounted on the connecting mechanism, several buffer mechanisms mounted on the buffer mounting plate 8, a chiseling mounting plate 9 mounted on the buffer mechanisms, and several chiseling devices mounted on the chiseling mounting plate 9.

[0054] The buffer mechanism includes clearance holes 10 respectively opened on the buffer mounting plate 8 and the roughened mounting plate 9, a stud 11 slidably disposed between the two clearance holes 10, and a limit nut 13 provided on the stud 11 with both ends abutting against the buffer mounting plate 8 and the roughened mounting plate 9 respectively.

[0055] This embodiment 4 provides a more detailed structure of the buffer mechanism based on embodiment 3. The buffer mechanism includes clearance holes 10 respectively opened on the buffer mounting plate 8 and the roughened mounting plate 9, a stud 11 slidably disposed between the two clearance holes 10, and a buffer spring 12 fitted on the stud 11 and abutting the buffer mounting plate 8 and the roughened mounting plate 9 at both ends respectively. A limit nut 13 is provided on the stud 11.

[0056] In this invention, the stud 11 is fixed between the buffer mounting plate 8 and the chiseling mounting plate 9 by the limiting nut 13. The buffer spring 12 is fitted on the stud 11 and its two ends are respectively pressed against the buffer mounting plate 8 and the chiseling mounting plate 9. When the chiseling device is under force, the chiseling mounting plate 9 moves synchronously with the chiseling device and squeezes the buffer spring 12. At this time, the buffer spring 12 buffers the impact force of the chiseling device, so that the chiseling device can stick to the tunnel wall, thereby facilitating the chiseling device to perform chiseling operations on the tunnel wall.

[0057] Example 5. (As shown) Figure 1-12 As shown, the present invention provides a shaving machine, including a mounting base 1, a pitch adjustment mechanism 2 disposed on the mounting base 1, an angle adjustment mechanism 3 disposed on the pitch adjustment mechanism 2, a rotating mechanism rotatably disposed on the angle adjustment mechanism 3, a connecting mechanism disposed on the rotating mechanism, and a shaving mechanism 4 movably disposed on the connecting mechanism.

[0058] The chiseling mechanism 4 includes a buffer mounting plate 8 movably mounted on the connecting mechanism, several buffer mechanisms mounted on the buffer mounting plate 8, a chiseling mounting plate 9 mounted on the buffer mechanisms, and several chiseling devices mounted on the chiseling mounting plate 9.

[0059] The chiseling device includes a support base 14 mirror-symmetrically disposed on the chiseling mounting plate 9, a chiseling head 15 rotatably disposed between the two support bases 14, and a plurality of chiseling teeth 16 disposed on the chiseling head 15.

[0060] This embodiment 5 provides a more detailed structure of the chiseling device based on embodiment 3. The chiseling device includes a support base 14 mirror-symmetrically disposed on the chiseling mounting plate 9, a chiseling head 15 rotatably disposed between the two support bases 14, and a plurality of chiseling teeth 16 disposed on the chiseling head 15.

[0061] When the present invention is used, when the chisel mounting plate 9 rotates under the drive of the rotating mechanism, the chisel teeth 16 will abut against the tunnel wall. As the chisel mounting plate 9 rotates, the chisel head 15 will also rotate synchronously, thereby realizing the chiseling operation on the tunnel wall.

(As shown) Figure 1-12 As shown, the present invention provides a shaving machine, including a mounting base 1, a pitch adjustment mechanism 2 disposed on the mounting base 1, an angle adjustment mechanism 3 disposed on the pitch adjustment mechanism 2, a rotating mechanism rotatably disposed on the angle adjustment mechanism 3, a connecting mechanism disposed on the rotating mechanism, and a shaving mechanism 4 movably disposed on the connecting mechanism.

[0065] The hydraulic cylinder A19 of this invention is connected to an external hydraulic station. When in use, the hydraulic cylinder A19 is started, and the hydraulic cylinder A19 pushes the floating arm 18 to rotate on the mounting base 1. The floating arm 18 drives the angle adjustment mechanism 3, the rotation mechanism, the connecting mechanism and the chiseling mechanism 4 to rotate synchronously, thereby realizing the height adjustment of the chiseling mechanism 4.

The telescopic adjustment mechanism includes a telescopic arm 27 that is slidably disposed within the floating arm 18 and connected to the angle adjustment mechanism 3, and a hydraulic cylinder C28 disposed within the floating arm 18 and connected to the telescopic arm 27.

[0070] The hydraulic cylinder C28 of this invention is connected to an external hydraulic station. When in use, the hydraulic cylinder C28 is started, and the hydraulic cylinder C28 pushes the telescopic arm 27 to slide within the floating arm 18. The floating arm 18 drives the angle adjustment mechanism 3, the rotation mechanism, the connecting mechanism and the chiseling mechanism 4 to move synchronously, thereby adjusting the height of the chiseling mechanism 4, so as to facilitate the chiseling mechanism 4 to perform chiseling operations on the tunnel wall.

[0071] The telescopic arm 27 of the present invention is provided with a hydraulic connecting seat A and a hydraulic connecting seat B. One end of the hydraulic cylinder C28 is connected to the hydraulic connecting seat A and the other end is connected to the hydraulic connecting seat B.

[0075] The hydraulic cylinder B22 of this invention is connected to an external hydraulic station. When in use, the hydraulic cylinder B22 is started, and the hydraulic cylinder B22 drives the adjusting seat 21 to move up or down on the angle connecting seat 20. The adjusting seat 21 drives the rotating mechanism, the connecting mechanism and the chiseling mechanism 4 to move synchronously, thereby further adjusting the position of the chiseling mechanism 4 so that the chiseling mechanism 4 can perform chiseling operations.

When in use, the hydraulic motor 23 is started, and the hydraulic motor 23 drives the connecting mechanism to rotate through the transmission mechanism.

[0080] In practical application, the hydraulic motor 23 drives the drive gear 25 to rotate, the drive gear 25 drives the driven gear 26 to rotate, the driven gear 26 drives the connecting mounting plate 5 to rotate, and the connecting mounting plate 5 drives the chiseling mechanism 4 to rotate through the universal joint 6, thereby realizing the transmission of power.

[0081] A method of using a shaving machine includes the following steps: S1. When the mounting base is moved to the desired position, hydraulic cylinder A is activated.

10. A method of using a chiseling machine according to any one of claims 1-9, characterized in that, Includes the following steps S1. When the mounting base is moved to the desired position, hydraulic cylinder A is activated. Hydraulic cylinder A drives the floating arm to swing up or down to adjust the angle of the floating arm. At the same time, hydraulic cylinder C is activated. Hydraulic cylinder C pushes the telescopic arm to slide in the floating arm, thereby adjusting the height of the chiseling device. S2. After the height of the floating arm is adjusted, start hydraulic cylinder B. Hydraulic cylinder B drives the adjusting seat to swing up or down. The adjusting seat drives the connecting mechanism and the chiseling mechanism to move synchronously through the rotating mechanism. S3. When the scabbing device comes into contact with the tunnel wall, it will squeeze the buffer mechanism. Since the scabbing device and the connecting mechanism are connected, the scabbing device will further fit into the tunnel wall. S4. Start the rotating mechanism. The rotating mechanism drives the chiseling mechanism to rotate synchronously through the connecting mechanism, thereby realizing the chiseling operation on the tunnel wall.
