Description

Technical Field

[0001] This utility model relates to the technical field of tunnel cutting angle adjustment mechanism, specifically to a compensable angle adjustment mechanism. Background Technology

[0002] Currently, tunnel excavation typically involves first locating the center point and then moving the excavating equipment to that position. However, errors can occur during the equipment movement, and significant errors can directly impact the accuracy of subsequent tunnel excavation. Therefore, improving the fine-tuning of the equipment's position has become a pressing issue. Utility Model Content

[0003] The purpose of this invention is to provide a compensable angle adjustment mechanism to solve at least one of the aforementioned problems in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An angle-compensating adjustment mechanism includes an adjustment frame, an upper double-rod hydraulic cylinder, a lower double-rod hydraulic cylinder, an upper adjustment hydraulic cylinder, a lower adjustment hydraulic cylinder, a lifting hydraulic cylinder, a fixed base, and a top hydraulic cylinder. The piston rod of the upper double-rod hydraulic cylinder is fixed to the upper end of the adjustment frame, and an upper rotating flange is rotatably connected to the upper sliding cylinder of the upper double-rod hydraulic cylinder. The piston rod of the lower double-rod hydraulic cylinder is fixed to the lower end of the adjustment frame, and a lower rotating flange is rotatably connected to the lower sliding cylinder of the lower double-rod hydraulic cylinder.

[0006] The upper adjusting cylinder is disposed between the upper sliding cylinder and the upper rotating flange, and the lower adjusting cylinder is disposed between the lower sliding cylinder and the lower rotating flange. The upper adjusting cylinder and the lower adjusting cylinder synchronously drive the upper rotating flange and the lower rotating flange to rotate along the Y-axis.

[0007] A lifting slide shaft is provided between the upper rotating flange and the lower rotating flange. A lifting slide sleeve is provided on the lifting slide shaft. A lifting frame is provided on the lifting slide sleeve. The lifting cylinder drives the lifting frame to move up and down. A fixed plate is provided at one end of the lifting frame. The fixed plate is used to install the actuator.

[0008] The lower end of the adjusting frame is rotatably connected to the fixed base on the X-axis, and the top hydraulic cylinder drives the adjusting frame to rotate along the X-axis.

[0009] In this technical solution, because the piston rod of the upper double-rod hydraulic cylinder is fixed to the upper end of the adjusting frame, and the piston rod of the lower double-rod hydraulic cylinder is fixed to the lower end of the adjusting frame, the adjusting frame, the upper double-rod hydraulic cylinder, and the lower double-rod hydraulic cylinder can form a stable frame structure. Since the upper sliding cylinder of the upper double-rod hydraulic cylinder is rotatably connected to an upper rotating flange, and the lower sliding cylinder of the lower double-rod hydraulic cylinder is rotatably connected to a lower rotating flange, the upper and lower rotating flanges can adjust their X-direction positions as the upper and lower sliding cylinders move along the X-direction. Because the upper adjusting cylinder is positioned between the upper sliding cylinder and the upper rotating flange, and the lower adjusting cylinder is positioned between the lower sliding cylinder and the lower rotating flange, the upper and lower adjusting cylinders synchronously drive the upper and lower rotating flanges to rotate along the Y-axis. Through the synchronous action of the upper and lower adjusting cylinders, the upper rotating flange can be adjusted. The adjustment of the rotation angle of the flange and the lower rotating flange along the Y-axis is used to compensate for the angle formed between the upper and lower rotating flanges and the X-axis. A lifting slide shaft is provided between the upper and lower rotating flanges, with a lifting sleeve on the shaft and a lifting frame on the sleeve. A lifting cylinder drives the lifting frame to move up and down. One end of the lifting frame has a fixed plate for mounting the actuator. The lifting cylinder drives the lifting frame to move up and down, thereby adjusting the actuator's position in the Y-axis. Since the lower end of the adjusting frame is rotatably connected to the fixed base on the X-axis, a top cylinder drives the adjusting frame to rotate along the X-axis. This overall drive of the adjusting frame by the top cylinder compensates for the angle formed between the actuator's position and the Y-axis.

[0010] In summary, this technical solution, by adjusting the position of the actuator in the XY direction and coordinating with angle-compensated rotation, can achieve a certain degree of small-range three-axis adjustment, thereby enabling accurate positioning of the actuator and improving the accuracy of tunnel trenching location.

[0011] Furthermore, in order to improve the stability of the lifting frame, two lifting slide shafts are provided between the upper rotating flange and the lower rotating flange, and the lifting frame is mounted on two lifting slide sleeves.

[0012] Furthermore, in order to improve the smoothness of the lifting drive, the lifting cylinder is located between two lifting shafts.

[0013] Furthermore, to facilitate the rotation drive of the adjustment frame, the adjustment frame is rotatably connected to the fixed base at the X-axis via a lower double-rod hydraulic cylinder.

[0014] Furthermore, in order to better achieve stable installation of the upper double-rod hydraulic cylinder and the lower double-rod hydraulic cylinder, the adjusting frame includes a left support and a right support. The two ends of the piston rod of the upper double-rod hydraulic cylinder are fixedly connected to the upper ends of the left support and the right support, respectively. The two ends of the piston rod of the lower double-rod hydraulic cylinder are fixedly connected to the lower ends of the left support and the right support, respectively. The two ends of the piston rod of the lower double-rod hydraulic cylinder are rotatably connected to the fixed seat.

[0015] The beneficial effects of this utility model are as follows: In this technical solution, since the piston rod of the upper double-rod cylinder is fixed to the upper end of the adjusting frame, and the piston rod of the lower double-rod cylinder is fixed to the lower end of the adjusting frame, the adjusting frame, the upper double-rod cylinder, and the lower double-rod cylinder can form a stable frame structure. Since the upper sliding cylinder of the upper double-rod cylinder is rotatably connected to an upper rotating flange, and the lower sliding cylinder of the lower double-rod cylinder is rotatably connected to a lower rotating flange, the upper and lower rotating flanges can adjust their X-direction positions as the upper and lower sliding cylinders move along the X-direction. Since the upper adjusting cylinder is positioned between the upper sliding cylinder and the upper rotating flange, and the lower adjusting cylinder is positioned between the lower sliding cylinder and the lower rotating flange, the upper and lower adjusting cylinders synchronously drive the upper and lower rotating flanges to rotate along the Y-axis. Through the synchronous action of the upper and lower adjusting cylinders, it is possible to... This system allows for adjustment of the rotation angle of the upper and lower rotating flanges along the Y-axis, compensating for the angle formed between the upper and lower rotating flanges and the X-axis. A lifting slide shaft is located between the upper and lower rotating flanges, with a lifting sleeve on the shaft and a lifting frame on the sleeve. A lifting cylinder drives the lifting frame to move up and down. One end of the lifting frame has a fixed plate for mounting the actuator. The lifting cylinder drives the lifting frame to move up and down, thereby adjusting the actuator's position in the Y-axis. Since the lower end of the adjusting frame is rotatably connected to the fixed base on the X-axis, a top cylinder drives the adjusting frame to rotate along the X-axis. This overall drive of the adjusting frame by the top cylinder compensates for the angle formed between the actuator's position and the Y-axis.

[0016] In summary, this technical solution, by adjusting the position of the actuator in the XY direction and coordinating with angle-compensated rotation, can achieve a certain degree of small-range three-axis adjustment, thereby enabling accurate positioning of the actuator and improving the accuracy of tunnel trenching location.

Detailed Implementation

[0031] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0032] Example 1:

[0033] like Figures 1-13 As shown, this embodiment provides a compensable angle adjustment mechanism, including an adjustment frame 1, an upper double-rod cylinder 2, a lower double-rod cylinder 3, an upper adjustment cylinder 4, a lower adjustment cylinder 5, a lifting cylinder 6, a fixed base 7, and a top cylinder 8. The piston rod of the upper double-rod cylinder 2 is fixed to the upper end of the adjustment frame 1. An upper rotating flange 9 is rotatably connected to the upper sliding cylinder 2.1 of the upper double-rod cylinder 2. Specifically, the upper rotating flange 9 is rotatably connected to the upper sliding cylinder 2.1 through a bearing. The piston rod of the lower double-rod cylinder 3 is fixed to the lower end of the adjustment frame 1. A lower rotating flange 10 is rotatably connected to the lower sliding cylinder 3.1 of the lower double-rod cylinder 3. Specifically, the lower rotating flange 10 is rotatably connected to the lower sliding cylinder 3.1 through a bearing.

[0034] The upper adjusting cylinder 4 is located between the upper sliding cylinder 2.1 and the upper rotating flange 9, and the lower adjusting cylinder 5 is located between the lower sliding cylinder 3.1 and the lower rotating flange 10. The upper adjusting cylinder 4 and the lower adjusting cylinder 5 synchronously drive the upper rotating flange 9 and the lower rotating flange 10 to rotate along the Y-axis 38.

[0035] A lifting slide shaft 11 is provided between the upper rotating flange 9 and the lower rotating flange 10. A lifting slide sleeve 12 is provided on the lifting slide shaft 11. A lifting frame 13 is provided on the lifting slide sleeve 12. The lifting cylinder 6 drives the lifting frame 13 to move up and down. A fixed plate 14 is provided at one end of the lifting frame 13. The fixed plate 14 is used to install the actuator.

[0036] The lower end of the adjusting frame 1 is rotatably connected to the fixed base 7 on the X-axis 15, and the top oil cylinder 8 drives the adjusting frame 1 to rotate along the X-axis 15.

[0037] In this technical solution, since the piston rod of the upper double-rod cylinder 2 is fixed to the upper end of the adjusting frame 1, and the piston rod of the lower double-rod cylinder 3 is fixed to the lower end of the adjusting frame 1, the adjusting frame 1, the upper double-rod cylinder 2, and the lower double-rod cylinder 3 can form a stable frame structure. Since the upper sliding cylinder 2.1 of the upper double-rod cylinder 2 is rotatably connected to the upper rotating flange 9, and the lower sliding cylinder 3.1 of the lower double-rod cylinder 3 is rotatably connected to the lower rotating flange 10, the upper rotating flange 9 and the lower rotating flange 10 can adjust their X-direction positions as the upper sliding cylinder 2.1 and the lower sliding cylinder 3.1 move along the X-direction. Since the upper adjusting cylinder 4 is located between the upper sliding cylinder 2.1 and the upper rotating flange 9, and the lower adjusting cylinder 5 is located between the lower sliding cylinder 3.1 and the lower rotating flange 10, the upper adjusting cylinder 4 and the lower adjusting cylinder 5 synchronously drive the upper rotating flange 9 and the lower rotating flange 10 to rotate along the Y-axis 38. Through the synchronous action of the upper adjusting cylinder 4 and the lower adjusting cylinder 5, the upper rotating flange 9 and the lower rotating flange 10 can be adjusted. The rotating flange 9 and the lower rotating flange 10 are adjusted by rotating along the Y-axis 38 to compensate for the angle formed between the upper rotating flange 9 and the lower rotating flange 10 and the X-axis. A lifting slide shaft 11 is provided between the upper rotating flange 9 and the lower rotating flange 10. A lifting slide sleeve 12 is provided on the lifting slide shaft 11, and a lifting frame 13 is provided on the lifting slide sleeve 12. The lifting cylinder 6 drives the lifting frame 13 to move up and down. A fixed plate 14 is provided at one end of the lifting frame 13. The fixed plate 14 is used to install the actuator. By driving the lifting frame 13 up and down through the lifting cylinder 6, the position of the actuator in the Y-direction is adjusted, thereby achieving the adjustment of the actuator's position in the Y-direction. Since the lower end of the adjusting frame 1 is rotatably connected to the fixed seat 7 on the X-axis 15, the top cylinder 8 drives the adjusting frame 1 to rotate along the X-axis 15. The overall drive of the adjusting frame 1 by the top cylinder 8 can compensate for the angle formed between the actuator's position and the Y-axis 38.

[0038] In summary, this technical solution, by adjusting the position of the actuator in the XY direction and coordinating with angle-compensated rotation, can achieve a certain degree of small-range three-axis adjustment, thereby enabling accurate positioning of the actuator and improving the accuracy of tunnel trenching location.

[0039] Example 2:

[0040] This embodiment is an optimization based on the above embodiment 1.

[0041] To improve the stability of the lifting frame 13, two lifting slide shafts 11 are provided between the upper rotating flange 9 and the lower rotating flange 10, and the lifting frame 13 is mounted on two lifting slide sleeves 12.

[0042] Example 3:

[0043] This embodiment is an optimization based on the above embodiment 2.

[0044] To improve the smoothness of the lifting drive, the lifting cylinder 6 is located between the two lifting shafts 11.

[0045] Example 4:

[0046] This embodiment is an optimization based on the above embodiment 1.

[0047] To facilitate the rotation drive of the adjustment frame 1, the adjustment frame 1 is rotatably connected to the fixed seat 7 at the X-axis 15 via the lower double-rod hydraulic cylinder 3. Specifically, the fixed seat 7 is rotatably connected to the piston rod of the lower double-rod hydraulic cylinder 3 via a bearing, and the piston rod of the lower double-rod hydraulic cylinder 3 is fixedly connected to the adjustment frame 1.

[0048] Example 5:

[0049] This embodiment is an optimization based on the above embodiment 4.

[0050] To better achieve stable installation of the upper double-rod cylinder 2 and the lower double-rod cylinder 3, the adjusting frame 1 includes a left support 1.1 and a right support 1.2. The piston rods of the upper double-rod cylinder 2 are fixedly connected to the upper ends of the left support 1.1 and the right support 1.2 respectively. The piston rods of the lower double-rod cylinder 3 are fixedly connected to the lower ends of the left support 1.1 and the right support 1.2 respectively. The piston rods of the lower double-rod cylinder 3 are rotatably connected to the fixed base 7 respectively.

[0051] It should be noted that this adjustment mechanism can be used in the following actuators, but is not limited to them. It can also be used in any other actuator that requires fine adjustment of the actuator position, such as an electric drill.

[0052] Specifically, the actuator includes a rotating frame 16, a rotating drive mechanism, a lead screw 17, a guide rod 18, a lead screw motor 19, and a tool holder 20. The lower end of the rotating frame 16 is mounted on the fixed plate 14 via the rotating drive mechanism. The upper end of the rotating frame 16 is provided with a tool holder mounting frame 21. Both ends of the lead screw 17 are rotatably connected to the tool holder mounting frame 21. Both ends of the guide rod 18 are fixedly connected to the tool holder mounting frame 21. The lead screw 17 and the guide rod 18 are arranged parallel to each other and both extend forward. Both ends of the tool holder 20 are slidably engaged with the corresponding guide rod 18. A lead screw nut 22 is threaded onto the lead screw 17. The lead screw nut 22 is fixedly connected to the tool holder 20. The lead screw motor 19 drives the lead screw 17 to rotate.

[0053] In this technical solution, the lower end of the rotating frame 16 is mounted on the fixed disk 14 via a rotary drive mechanism. The rotating frame 16 is driven to rotate by the rotary drive mechanism, which in turn drives the tool holder mounting frame 21 to rotate circumferentially. The two ends of the lead screw 17 are rotatably connected to the tool holder mounting frame 21, and the two ends of the guide rod 18 are fixedly connected to the tool holder mounting frame 21. The lead screw 17 and guide rod 18 are parallel and both extend forward. The two ends of the tool holder 20 are slidably engaged with the corresponding guide rod 18. A lead screw nut 22 is threaded onto the lead screw 17, and the lead screw nut 22 is fixedly connected to the tool holder 20. The lead screw motor 19 drives the lead screw 17 to rotate. In specific operation, the rotary drive mechanism drives the rotating frame 16 circumferentially. While rotating, the lead screw 17 is driven to rotate by the lead screw motor 19. The lead screw 17 drives the cutter holder 20 to move along the guide rod 18 through the lead screw nut 22. During this process, the cutter holder 20 moves forward step by step, driving the cutter head assembly forward step by step. The circumferential rotation trajectory of the rotating frame 16 determines the size of the tunnel. During the continuous circumferential rotation, the cutter head assembly gradually moves towards the deeper soil layer, making the travel trajectory of the cutter head assembly in the soil layer similar to a spiral propulsion method. The cutting depth is continuously increased, thus enabling continuous circular trajectory grooving. There is no need for manual use of water-cooled drills to repeatedly cut small-sized soil. The entire grooving process is highly automated, efficient, and saves time and labor.

[0054] It also includes a cutter head drive assembly. The cutter holder 20 is provided with multiple hollow arms 23 extending forward. The multiple hollow arms 23 are distributed at intervals along the cutting trajectory. The front end of the hollow arm 23 is provided with a cutter head assembly 24. The cutter head drive assembly includes a first synchronous pulley 25, a second synchronous pulley 26, a synchronous belt, and a cutter head motor 27. The synchronous belt passes through both ends of the hollow arm 23 and is connected to the first synchronous pulley 25 and the second synchronous pulley 26 respectively. The first synchronous pulley 25 is rotatably connected to the free end of the hollow arm 23. The cutter head assembly 24 is coaxially fixed on the first synchronous pulley 25. The cutter head motor 27 is provided on the cutter holder 20 and drives the second synchronous pulley 26 to rotate.

[0055] The hollow arm 23 facilitates the installation of the cutter head assembly 24. At the same time, the synchronous pulley drive allows the cutter head motor 27 to be installed in a position away from the cutter head assembly 24, which facilitates subsequent use and maintenance without affecting the drive of the cutter head assembly 24.

[0056] The rotating frame 16 drives multiple cutter head assemblies 24 to move along a circular trajectory. The cutter head assembly 24 includes multiple cutter heads 28 arranged coaxially. The rotation axis A of the cutter head 28 is perpendicular to the rotation axis B of the rotating frame 16. The radius of the circular motion trajectory 29 of any cutter head 28 is different. The circular motion trajectories 29 of all cutter heads 28 are connected to each other to achieve a cutting path without soil residue.

[0057] In this technical solution, the rotating frame 16 drives multiple cutter head assemblies 24 to move along a circular trajectory, thereby achieving circular trajectory drive for the cutter head assemblies 24. Since the cutter head assembly 24 includes multiple coaxially arranged cutter heads 28 (i.e., layered installation), the rotation axis A of the cutter head 28 is perpendicular to the rotation axis B of the rotating frame 16. The cutter head 28 rotates about its rotation axis A. Simultaneously, the multiple layered cutter heads 28 move in a circular trajectory about the same rotation axis B. During this process, the circular trajectories of different cutter heads 28 are different, enabling cutting with different circular trajectories from multiple cutter heads 28. This allows for the cutting of a relatively wide annular cutting groove even with a thinner individual cutter head 28, facilitating subsequent removal of soil from the center of the annular cutting groove. The thinner individual cutter head 28 results in a smaller cutting surface, improving the smoothness of soil cutting and increasing cutting efficiency. Since the radius of the circular motion trajectory 29 of any cutterhead 28 in the multiple cutterhead assemblies 24 is different, the number of cutterheads 28 can be maximized to cut a wider annular cutting groove, which is more conducive to the removal of soil in the middle of the annular cutting groove. Because the circular motion trajectories 29 of all cutterheads 28 are interconnected to achieve a cutting path without soil residue, the cutting groove is cleaner, the tunnel inner wall is smoother, and there is no need to clean the tunnel wall after cutting, thus improving the tunnel excavation progress and work efficiency.

[0058] A water-cooling pipe 30 is provided on the tool holder 20 near the hollow arm 23. The water-cooling pipe 30 is connected to an external water source to cool the tool disc assembly 24. A suction pipe 31 is provided on the tool holder 20. The suction pipe 31 is connected to an external suction device to discharge the material generated in the cutting groove. A first rotary joint 32 is provided in the middle of the fixed plate 14. A second rotary joint 33 is provided inside the first rotary joint 32. The first rotary joint 32 is connected to the water-cooling pipe 30, and the second rotary joint 33 is connected to the suction pipe 31.

[0059] The first rotary joint 32 allows the water cooling pipe 30 to move in conjunction with the rotating frame 16 without affecting the operation of the water circuit. The second rotary joint 33 allows the suction pipe 31 to move in conjunction with the rotating frame 16 without affecting the suction operation.

[0060] The rotary drive mechanism includes a rotary motor 34, an outer ring 35, an internal gear ring 36, and a gear 37. The rotary motor 34 is located on the outside of the fixed disk 14. The outer ring 35 is coaxially fixed on the inside of the fixed disk 14. The internal gear ring 36 is coaxially located inside the outer ring 35 and the two are rotatably engaged. The internal gear ring 36 is fixedly connected to the lower end of the rotating frame 16. The gear 37 meshes with the internal gear ring 36, and the rotary motor 34 drives the gear 37 to rotate.

[0061] The rotary motor 34 drives the gear 37 to rotate, the gear 37 drives the internal gear ring 36 to rotate, and the internal gear ring 36 drives the rotating frame 16 to rotate, which can provide the rotating frame 16 with continuous and stable rotational power.

[0062] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
