Description

Technical Field

[0001] The present invention relates to the technical field of concrete component manufacturing equipment, and in particular to a concrete block cutting device. Background Art

[0002] The concrete block cutting device is used to cut concrete blocks into required sizes and shapes. During the manufacturing and processing process, cutting needs to be carried out according to actual uses. Especially in the scenario of small batch production requirements, using a cutting device to replace mold processing can significantly reduce costs. Especially in the customized construction scenario, achieving rapid shape adaptation through equipment adjustment is more economically viable for engineering.

[0003] Traditional cutting devices are widely used in the field of concrete block processing. However, due to the limitations of their structures and working principles, there are often some problems that cannot be ignored. For example, traditional concrete block cutting devices have a single function and can only use one of a saw blade or a cutting wire for cutting, resulting in limited usage scenarios. Saw blade cutting is suitable for most conventional cutting tasks, but it is inadequate for complex shapes or deep cutting. Although the cutting wire can perform some special shape cuttings, the efficiency is low, and it is difficult to achieve precise control. This single mode limits the application range of the device and cannot meet diverse construction needs. In addition, traditional devices do not have a rapid reciprocating cutting function, and when operating with handheld devices, there are safety hazards. Summary of the Invention

[0004] In view of the problems existing in the prior art that the cutting device has a single function, cannot adapt to complex usage requirements, and does not have a reciprocating cutting function, which affects safety, a concrete block cutting device is thus proposed.

[0005] Its purpose is to integrate different cutting tools in the cutting device to improve adaptability and have two cutting modes to meet different usage needs.

[0007] Further, a hexagonal groove is formed at one end of the power shaft close to the transmission shaft, and a hexagonal prism is provided at one end of the transmission shaft close to the power shaft. The hexagonal prism is slidably connected to the hexagonal groove.

[0008] Further, the driving unit includes a driving wheel disposed in the middle of the transmission shaft, an output shaft disposed at the top of the housing close to the transmission shaft, a driven wheel disposed at one end of the output shaft close to the main machine, a spline disposed in the middle of the output shaft, a sliding sleeve disposed outside the spline, a housing disposed at the bottom of the sliding sleeve, a push rod disposed at one end of the transmission shaft away from the main machine, and a gear pair disposed at one end of the output shaft away from the main machine.

[0009] Further, a gear ring is provided inside the sliding sleeve. The gear ring is slidably connected to the outside of the spline. A limiting hole is formed on one side of the sliding sleeve close to the main machine, and the diameter of the limiting hole matches the diameter of the output shaft.

[0010] Further, a moving hole is formed on one side of the housing close to the main machine, and the diameter of the moving hole is larger than the maximum swing amplitude of the housing.

[0011] Further, the cutting mechanism includes a circular saw disposed on the side of the housing away from the main machine, a sheave disposed on the side of the gear pair away from the output shaft. The sheave is meshed with the inside of the circular saw, and a wire cutting unit is disposed inside the sheave.

[0012] Further, the wire cutting unit includes a cutting wire disposed inside the sheave, rotating arms symmetrically disposed at the top and bottom of the housing, rotating wheels disposed at one end of the rotating arms away from the main machine, sliding grooves symmetrically disposed on the side of the housing close to the main machine, sliders disposed inside the sliding grooves, a tensioning wheel disposed at the front of the sliders, a moving frame commonly disposed on the side of the two sliders away from the tensioning wheel.

By setting up a driving unit, power and motion control are provided for the cutting mechanism, enabling the output shaft to achieve rapid forward and reverse rotation, meeting the requirements of reciprocating cutting, and allowing the device to flexibly switch the power path according to different cutting needs, meeting diverse cutting requirements.

[0019] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will give a detailed description of the specific implementation manners of the present invention with reference to the accompanying drawings of the specification.

[0020] Example 1, referring to Figures 1-13 , which is the first embodiment of the present invention, provides a concrete block cutting device, including a main machine 1, an outer shell 2 fixedly connected to one side of the main machine 1, and further including a switching mechanism 3 installed inside the outer shell 2, and a cutting mechanism 4 installed on the side of the outer shell 2 away from the main machine 1 for cutting concrete; the switching mechanism 3 includes a power shaft 31 rotatably connected inside the outer shell 2, and after the power shaft 31 rotates, it provides power for the cutting mechanism 4, a transmission shaft 32 slidably connected to the end of the power shaft 31 away from the main machine 1, and the transmission shaft 32 transmits the torque of the power shaft 31 to other components, a stopper 33 fixedly connected to the end of the transmission shaft 32 close to the power shaft 31, and after the stopper 33 moves, it drives the rotating shaft to move together, a moving rod 34 rotatably connected to the outside of the stopper 33, and when the moving rod 34 moves horizontally, it drives the stopper 33 to move synchronously, a pin 35 fixedly connected to the end of the moving rod 34 away from the stopper 33, two slots 36 fixedly connected to the front part of the outer shell 2 close to the pin 35, and after the pin 35 cooperates with the slots 36, it will not be able to move, and a driving unit assembled in the middle of the transmission shaft 32.

[0021] Specifically, after the main machine 1 is started, it drives the power shaft 31 to rotate, providing power for the device to cut concrete. The transmission shaft 32 rotates synchronously with the power shaft 31 and can transmit the torque from the power shaft 31. The stopper 33 can move after being subjected to forces on both sides, and drives the transmission shaft 32 to move together while moving. Pushing the moving rod 34 can drive the stopper 33 to move. The pin 35 moves synchronously with the moving rod 34. After the pin 35 is inserted into the slot 36, the moving rod 34 will be restricted from moving, and thus the stopper 33 and the transmission shaft 32 will also be restricted.

[0022] Referring to Figure 4 , a hexagonal groove is provided at the end of the power shaft 31 close to the transmission shaft 32, and a hexagonal prism is provided at the end of the transmission shaft 32 close to the power shaft 31, and the hexagonal prism is slidably connected to the hexagonal groove.

[0023] Specifically, the power shaft 31 enables the transmission shaft 32 to rotate synchronously with itself through the cooperation between the hexagonal groove and the hexagonal prism.

[0024] Referring to Figures 4-6 , the drive unit includes a driving wheel 37 fixedly connected to the middle of the transmission shaft 32, an output shaft 38 rotatably connected to the housing 2 near the top of the transmission shaft 32, a driven wheel 39 fixedly connected to one end of the output shaft 38 close to the main machine 1, a spline 310 fixedly connected to the middle of the output shaft 38, a sliding sleeve 311 slidably connected to the outside of the spline 310, a cover 312 fixedly connected to the bottom of the sliding sleeve 311, a push rod 313 fixedly connected to the end of the transmission shaft 32 away from the main machine 1, and a gear pair 314 fixedly connected to the end of the output shaft 38 away from the main machine 1.

[0025] Specifically, the driving wheel 37 rotates together with the transmission shaft 32. When the driving wheel 37 meshes with the driven wheel 39, it will rotate synchronously with the output shaft 38 through the driven wheel 39. The output shaft 38 drives the spoke to rotate synchronously. The gear pair 314 drives the circular saw 41 to rotate through the grooved pulley 42, or drives the cutting line 43 to perform cutting. The spline 310 will rotate synchronously with the output shaft 38. When the spline 310 cooperates with the sliding sleeve 311, the sliding sleeve 311 will drive the output shaft 38 to rotate quickly forward and backward through the spline 310. When the transmission shaft 32 moves toward both sides, it will drive the push rod 313 to move together, and the transmission shaft 32 can drive the push rod 313 to rotate synchronously. When the push rod 313 moves toward both sides, it will drive the cover 312 and the sliding sleeve 311 to move synchronously. When the push rod 313 rotates, it will push the inner wall of the cover 312, causing the cover 312 to swing around the axis of the sliding sleeve 311. When the sliding sleeve 311 cooperates with the spline 310, the driving wheel 37 and the driven wheel 39 will be in a non-contact state. The gear pair 314 can transmit the power of the output shaft 38 to drive the grooved pulley 42 to rotate. The gear pair 314 includes two bevel gears of different sizes.

[0026] Referring to Figures 6-9 , a gear ring is provided on the inner side of the sliding sleeve 311. The gear ring is slidably connected to the outside of the spline 310, and a limiting hole is provided on one side of the sliding sleeve 311 close to the main machine 1. The diameter of the limiting hole matches the diameter of the output shaft 38.

[0027] Specifically, the sliding sleeve 311 is connected to the spline 310 through the gear ring on the inner wall, so that the sliding sleeve 311 will not drive the spline 310 to move when moving along the axis of the spline 310. When the sliding sleeve 311 swings with the cover 312, it will drive the spline 310 to rotate. The rotation of the spline 310 drives the output shaft 38 to rotate synchronously. And the sliding sleeve 311 is cooperated with the output shaft 38 through the limiting hole on the outside of the output shaft 38, so that itself and the output shaft 38 are in a coaxial state.

[0028] Referring toFigure 8 , on one side of the housing 312 close to the main machine 1, a moving hole is opened, and the diameter of the moving hole is greater than the maximum swing amplitude of the housing 312.

[0029] Specifically, the transmission shaft 32 extends into the interior of the housing 312 through the moving hole and is connected to the push rod 313, and the existence of the moving hole prevents the housing 312 from colliding with the transmission shaft 32 during the swinging process.

[0030] Embodiment 2, refer to Figures 9-13 , is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the cutting mechanism 4 includes a circular saw 41 rotatably connected to the side of the housing 2 away from the main machine 1, a sheave 42 fixedly connected to the side of the gear pair 314 away from the output shaft 38, the sheave 42 is meshed and connected to the inner side of the circular saw 41, and a wire cutting unit assembled inside the sheave 42.

[0031] Specifically, after being driven by the sheave 42, the circular saw 41 rotates, so as to be able to cut the concrete block.

[0032] Refer to Figures 9-13 , the wire cutting unit includes a cutting wire 43 sleeved inside the sheave 42, swing arms 44 symmetrically rotatably connected to the top and bottom of the housing 2, a runner 45 rotatably connected to the end of the swing arm 44 away from the main machine 1, a chute 46 fixedly connected to the side of the housing 2 close to the main machine 1, a slider 47 slidably connected inside the chute 46, a tensioning wheel 48 rotatably connected to the front of the slider 47, a moving frame 49 commonly fixedly connected to the sides of the two sliders 47 away from the tensioning wheel 48, the cutting wire 43 is sequentially sleeved outside the sheave 42, the tensioning wheel 48 and the runner 45, a stud 410 threadedly connected to the middle of the moving frame 49, and support plates 411 symmetrically rotatably connected to both ends of the stud 410, and the side of the support plate 411 close to the slider 47 is fixedly connected to the housing 2.

[0033] Specifically, after being stressed, the swing arm 44 rotates around the connection point with the housing 2, and the swing arm 44 can block the debris splashed after the circular saw 41 cuts the concrete. When the side of the runner 45 away from the main machine 1 is stressed, it will push the corresponding swing arm 44 to rotate away from the circular saw 41. The chute 46 can restrict the moving track of the slider 47. When the slider 47 moves, it drives the tensioning wheel 48 to move together. The two support plates 411 restrict the stud 410 so that it can only rotate in place. After the stud 410 rotates, it drives the moving frame 49 to move horizontally. The moving frame 49 drives the two sliders 47 to move synchronously. The cutting wire 43 is simultaneously sleeved outside the sheave 42, the runner 45 and the tensioning wheel 48. By moving the tensioning wheel 48 towards the main machine 1, the cutting wire 43 can be tightened. After the sheave 42 rotates, it will drive the cutting wire 43 to move. The cutting wire 43 in the moving state can cut the concrete.

[0034] Reference Figure 11 and Figure 12 In the middle of the moving frame 49, a threaded hole is formed, and the inner wall of the threaded hole is threadedly connected to the outer wall of the stud 410.

[0035] Specifically, the moving frame 49 is connected to the stud 410 through the threaded hole. After the stud 410 rotates, it will drive the moving frame 49 to move along the axis of the stud 410, and the rest of the structure is the same as that of Embodiment 1.

[0036] Combining Embodiments 1-2, the working principle of the present invention is as follows: After the main machine 1 is started, the power shaft 31 drives the transmission shaft 32 to rotate. The transmission shaft 32 drives the driving wheel 37 and the push rod 313 to rotate synchronously. While the push rod 313 rotates, it swings by pushing the inner wall of the push cover 312 and drives the sliding sleeve 311 to rotate forward and backward. When the sliding sleeve 311 is in a mating state with the spline 310, the spline 310 will move synchronously with the sliding sleeve 311 and drive the output shaft 38 to rotate forward and backward. The output shaft 38 drives the sprocket 42 and the circular saw 41 to rotate forward and backward through the gear pair 314. When the circular saw 41 cuts the concrete block in a state of forward and backward rotation at a small angle and high frequency, it can avoid debris splashing, reduce the risk of jamming, and because the rotation angle is small, when the human body accidentally touches the circular saw 41, the rotation amplitude of the circular saw 41 is less than the stretching limit of the skin, avoiding skin damage and improving the safety of operating the handheld device; When it is necessary to switch to a more efficient cutting mode, the moving rod 34 can be moved towards the main machine 1, so that the pin 35 is inserted into the slot 36 on the side close to the main machine 1. At this time, the moving rod 34 moves the transmission shaft 32 towards the main machine 1 through the stop block 33, so that the driving wheel 37 and the driven wheel 39 enter the meshing state. At the same time, the transmission shaft 32 moves the cover 312 and the sliding sleeve 311 through the push rod 313, releasing the connection between the sliding sleeve 311 and the spline 310. At this time, when the transmission shaft 32 rotates, it will drive the output shaft 38 to rotate through the driving wheel 37 and the driven wheel 39. The output shaft 38 makes the sprocket 42 rotate unidirectionally through the gear pair 314, and the sprocket 42 drives the circular saw 41 to rotate at high speed, so as to cut the concrete; When the cutting path of the concrete is non-linear, the outer shell 2 is opened, the circular saw 41 is taken out, and the cutting wire 43 is sleeved outside the side tension wheel 48 and the runner 45 of the sprocket 42. The rotation of the sprocket 42 drives the cutting wire 43 to move, forming a wire saw. The wire saw can cut non-linear trajectories, meeting different concrete processing requirements, and through the same operation as the circular saw 41 cutting, the wire saw also has the functions of unidirectional cutting and reciprocating cutting.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
