[0015] Beneficial effects:

[0016] 1. The outer and inner hubs enhance the structural strength and compressive strength of the sleeve and provide support for the slide rail. The sliding of the balls on the inner side of the slide rail reduces resistance to the movement of the movable plate, thereby reducing the loss of kinetic energy during impact. The structure of the corner bracket and the limit bracket limits the movement trajectory of the movable bracket.

The elasticity of the conical spring achieves the effect of multiple impacts at a single point in a single stamping operation, further avoiding kinetic energy waste and achieving a better impact effect.

[0017] 2. The position of motor one is limited by the housing and the limiting shaft, and the bolt assembly method facilitates the removal of motor one. The clamp connects turntable one and turntable two and facilitates their separation. During the force application process, the operation of motor one drives turntable one to rotate, and the clamp drives turntable two to rotate, achieving the angle adjustment function of the fixed sleeve and telescopic rod. By adjusting the angle and extending the telescopic rod, force is applied to the bearing, which drives the drive rod to adjust its position. The limiting sleeve limits the movement trajectory of the drive rod. This external drive structure facilitates the maintenance of the drive structure, and the dual-drive structure enhances the impact energy of the punch.

[0018] 3. The casters provide stable support for the movement of the support base. By pressing the pressure plate, the screw contacts the ground, and the movement trajectory of the movable shaft is limited by the angle bracket and kit, thereby limiting the adjustment trajectory of the cover plate and hollow disc. The operation of the No. 2 motor drives the drive gear to rotate, which in turn drives multiple sets of linkage gears to rotate, achieving the synchronous rotation of multiple sets of screws, thus fixing them to the ground, improving the efficiency and stability of the fixing work, and facilitating the movement and fixing of the rock breaking device during the track construction process.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0031] like Figures 1 to 4 As shown, a rock breaking device for tunnel construction includes an impact mechanism, a drive mechanism, and a fixing mechanism. The impact mechanism includes a sleeve 1, with an outer hub 2 and an inner hub 3 mounted on the surface of the sleeve 1. A slide rail 4 is installed between the inner hubs 3. A movable disc 5 is provided on the inner side of the inner hub 3. A slider 6 is mounted on the outer surface of the movable disc 5. A ball bearing 7 is rotatably connected to the inner side of the slider 6. A housing 8 is mounted at the front end of the movable disc 5. A movable frame 9 is provided on the inner side of the housing 8. A limit frame 10 is installed on the inner side of the housing 8. An edge frame 11 is mounted on the outer surface of the movable frame 9. A conical spring 12 is installed between the movable frame 9 and the housing 8. A buffer pad 13 is installed on the inner side of the housing 8. A punch 14 is mounted at the front end of the movable frame 9. A connecting shaft 15 is mounted at the rear end of the movable disc 5. A drive rod 16 is mounted at the rear end of the connecting shaft 15.

[0032] The outer hub 2 and inner hub 3 enhance the structural strength and compressive strength of the sleeve 1 and provide support for the slide rail 4. The sliding of the ball bearing 7 on the inner side of the slide rail 4 reduces the resistance to the movement of the movable disc 5, thereby reducing the loss of kinetic energy during the impact. The structure of the corner bracket 11 and the limit bracket 10 limits the movement trajectory of the movable frame 9. The conical spring 12 and the buffer pad 13 achieve the buffering effect on the punch 14, and the housing 8 provides space for buffering. The elastic force of the conical spring 12 achieves the effect of multiple impacts at a single point in a single stamping operation, further avoiding the waste of kinetic energy and achieving a better impact effect.

[0033] Specifically, such as Figure 4 As shown, the outer hub 2 and the inner hub 3 are evenly spaced. The outer hub 2 is mounted on the outer surface of the sleeve 1, and the inner hub 3 is mounted on the inner side of the sleeve 1. The slider 6 and the slide rail 4 are evenly spaced around the circumference. The slider 6 is slidably connected to the inner side of the slide rail 4, and the ball bearing 7 is in contact with the inner wall of the slide rail 4.

[0034] The outer hub 2 and inner hub 3 enhance the structural strength and compressive strength of the sleeve 1 and provide support for the slide rail 4. The sliding of the slider 6 on the inner side of the slide rail 4 limits the movement trajectory of the movable disk 5. The sliding of the ball bearing 7 on the inner side of the slide rail 4 reduces the resistance to the movement of the movable disk 5, thereby reducing the loss of kinetic energy during the impact.

[0035] Specifically, such as Figure 4 As shown, the limiting frame 10 and the corner frame 11 are engaged with each other. The limiting frame 10 and the corner frame 11 are distributed at equal intervals around the circumference. The conical spring 12 is sleeved on the outer surface of the buffer pad 13. The buffer pad 13 and the movable frame 9 are located on the same horizontal line.

[0036] The movement trajectory of the movable frame 9 is limited by the structure of the corner bracket 11 and the limiting bracket 10. The cone spring 12 and the buffer pad 13 achieve the buffering effect on the force of the punch 14. The housing 8 provides space for buffering. The elastic force of the cone spring 12 achieves the effect of multiple impacts at a single point in a single stamping operation, further avoiding kinetic energy waste and achieving a better impact effect.

[0037] Specifically, such as Figure 3 As shown, a sealing plate 17 is installed at the rear end of the sleeve 1, and a limiting sleeve 18 is installed on the inner side of the sealing plate 17. The limiting sleeve 18 is fitted on the outer surface of the drive rod 16, and feet 19 are installed on both sides of the lower surface of the sleeve 1.

[0038] The sealing plate 17 achieves the effect of sealing the rear end of the sleeve 1, the limiting sleeve 18 limits the movement trajectory of the drive rod 16, and the foot 19 provides stable support for fixing the position of the sleeve 1.

[0039] Specifically, such as Figure 5 As shown, the drive mechanism includes a housing 20, a first motor 21 is inserted into the inner side of the housing 20, and limit grooves are opened on both sides of the outer surface of the first motor 21. Limit shafts 22 are installed on both sides of the inner wall of the housing 20. The limit shafts 22 are inserted into the inner side of the limit grooves. The first motor 21 and the housing 20 are fixedly connected by bolts.

[0040] The position of the first motor 21 is limited by the housing 20 and the limiting shaft 22, and the bolt assembly method facilitates the removal of the first motor 21. The limiting shaft 22 achieves the initial limitation function of the position of the first motor 21, providing a prerequisite for the bolt assembly.

[0041] Specifically, such as Figure 6 As shown, the output end of motor 21 is equipped with turntable 23, and turntable 24 is provided on the upper surface of turntable 23. The outer surfaces of turntable 23 and turntable 24 are fixedly connected by clamps 25, and the upper surface of turntable 24 is equipped with a fixing sleeve 26.

[0042] The clamp 25 enables the connection between turntable 23 and turntable 24 and facilitates the separation of turntable 23 and turntable 24.

[0043] Specifically, such as Figure 6 As shown, a telescopic rod 27 is installed on the inner side of the fixed sleeve 26, and a bearing 28 is provided between the telescopic rods 27. The bearing 28 is rotatably connected to the output end of the telescopic rod 27, and the bearing 28 is fixedly connected to the rear end of the drive rod 16.

[0044] During the force application process, the operation of motor 21 drives turntable 23 to rotate, and clamp 25 drives turntable 24 to rotate, achieving the angle adjustment function of fixed sleeve 26 and telescopic rod 27. By adjusting the angle and extending and retracting the telescopic rod 27, force is applied to bearing 28, driving drive rod 16 to adjust its position. The movement trajectory of drive rod 16 is limited by limit sleeve 18. This external drive structure provides convenience for the maintenance of the drive structure, and the dual-drive structure enhances the impact energy of punch 14.

[0045] Specifically, such as Figure 7 As shown, the fixing mechanism includes a support base 29, which is mounted on the lower surface of the foot base 19. A T-shaped frame 30 is mounted on the lower surface of the support base 29, and the T-shaped frame 30 is fixedly connected to the housing 20. A support frame 31 is mounted on the inner side of the support base 29. The support frame 31 is configured as a cross structure. A caster wheel 32 is rotatably connected to the lower surface of the support base 29.

[0046] The support base 29 and T-shaped frame 30 provide stable support for the foot 19 and the housing 20. The casters 32 reduce the resistance to the movement of the support base 29, and the support frame 31 improves the structural stability of the support base 29 while reducing the load.

[0047] Specifically, such as Figure 8 As shown, both sides of the support base 29 are equipped with angle brackets 33, the bottom of the angle brackets 33 is equipped with a kit 34, the inner side of the kit 34 is slidably connected to a movable shaft 35, the top of the movable shaft 35 is equipped with a pressure plate, the bottom of the movable shaft 35 is equipped with a connecting frame 36, the bottom of the connecting frame 36 is equipped with a cover plate 37, and the inner side of the connecting frame 36 is equipped with a second motor 38.

[0048] The movement trajectory of the movable shaft 35 is limited by the angle bracket 33 and the kit 34, thereby limiting the adjustment trajectory of the cover plate 37 and the hollow plate 39.

[0049] Specifically, such as Figure 8 As shown, a hollow disk 39 is mounted on the lower surface of the cover plate 37, and a drive gear 40 is mounted at the center of the hollow disk 39. The output end of the second motor 38 passes through the upper surface of the cover plate 37 and is fixedly connected to the drive gear 40. A linkage gear 41 is rotatably connected to the inner edge of the hollow disk 39. A screw 42 is mounted on the lower surface of the linkage gear 41, and one end of the screw 42 passes through the lower surface of the hollow disk 39.

[0050] By pressing the pressure plate, the screw 42 comes into contact with the ground. The operation of the second motor 38 drives the drive gear 40 to rotate, which in turn drives multiple sets of linkage gears 41 to rotate, achieving the synchronous rotation of multiple sets of screws 42. This fixes the screws to the ground, improving the efficiency and stability of the fixing work and facilitating the movement and fixing of the rock breaking device during the track construction process.

[0051] Working principle:

[0052] The position of motor 21 is limited by the sleeve 20 and the limiting shaft 22, and the bolt assembly method facilitates the removal of motor 21. The clamp 25 connects turntable 23 and turntable 24, and facilitates their separation. During force application, motor 21 rotates turntable 23, and clamp 25 rotates turntable 24, thus achieving the angle adjustment function of the fixing sleeve 26 and the telescopic rod 27. The angle adjustment and extension / retraction of the telescopic rod 27 applies force to the bearing 28, driving the drive rod 16 to adjust its position. The movement trajectory of the drive rod 16 is limited by the limiting sleeve 18. This external drive structure facilitates maintenance of the drive structure. The dual-drive structure enhances the impact energy of the punch 14. The outer hub 2 and inner hub 3 improve the structural strength and compressive resistance of the sleeve 1 and provide support for the slide rail 4. The sliding of the balls 7 on the inner side of the slide rail 4 reduces resistance to the movement of the movable disc 5. To reduce kinetic energy loss during impact, the structure of the corner bracket 11 and the limiting bracket 10 limits the movement trajectory of the movable bracket 9. The conical spring 12 and the buffer pad 13 achieve a buffering effect on the force on the punch 14, and the housing 8 provides space for buffering. The elasticity of the conical spring 12 achieves the effect of multiple impacts at a single point in a single punching operation, further avoiding kinetic energy waste and achieving a better impact effect. The universal wheel 32 provides stable support for the movement of the support base 29. By pressing the pressure plate, the screw 42 is brought into contact with the ground, and the movement trajectory of the movable shaft 35 is limited by the corner bracket 33 and the kit 34, thereby limiting the adjustment trajectory of the cover plate 37 and the hollow plate 39. The operation of the second motor 38 drives the drive gear 40 to rotate, thereby driving multiple sets of linkage gears 41 to rotate, achieving the effect of synchronous rotation of multiple sets of screws 42, and thus fixing them to the ground, improving the efficiency and stability of the fixing work, and facilitating the movement and fixing of the rock crushing device during the track construction process.
