Description

Technical Field

[0001] The utility model belongs to the technical field of stone cutting, and particularly relates to a curb cutting device. Background Art

[0002] A curb is a marking stone arranged between a road surface and other structures. Curb stones are generally required to be arranged between the median strip and the road surface of an urban road, between the sidewalk and the road surface, and often required to be arranged at the edge of the central median strip of a highway, the right edge of the driving lane or the outer edge of the road shoulder. And the surface of the curb needs to be cut. The main purpose of cutting is to allow the curb to have a certain amount of expansion space and freedom when affected by various external and internal forces, so as to reduce cracks, deformations, etc. that occur during the stress process of the curb.

[0003] In the related art (publication number: CN211420788U), a rapid cutting device for slip-form curbs is disclosed. A support frame is fixed at one end of a handcart. An extension frame extends outward from the upper end of the support frame. A connecting frame is fixed at the tail of the extension frame. A through groove is provided in the middle of the support frame, which is open at the upper end and penetrates left and right. The middle of the extension frame is a cavity that penetrates up, down, left, and right and communicates with the through groove. The left side of the connecting frame is connected to a fixed cutter head, and the lower side is connected to a movable cutter head. The lower right side of the fixed cutter head is connected to a guard plate in an L-shaped structure. The lower left side of the movable cutter head is a cutting edge. A foot pedal is arranged above the handcart. The left side of the foot pedal is a pull rod that extends upward and is fixedly connected to the foot pedal. The upper end of the pull rod extends obliquely upward to the left and is integrally connected to a connecting rod. The end of the connecting rod and the movable cutter head are hinged to the connecting frame through the same rotating shaft. The utility model is used for rapid cutting of curbs. After the handcart is in place, a person steps on the foot pedal to complete the cutting, which is convenient and fast.

[0004] However, during the existing cutting and processing of curbs, only one gap can be cut at a time. If it is desired to cut equally spaced gaps on the surface of the curb, the steps of repeated cutting, moving the equipment, and cutting again are required. That is, when the existing curb cutting device is used, only one gap can be cut and processed at a time, and the cutting efficiency is relatively low. Content of the Utility Model

[0013] The curb cutting device of the present utility model, compared with the prior art, has the beneficial effects as follows:

[0014] 1. In view of the problem that the existing curb cutting device can only cut one slit at a time and has low cutting efficiency, the utility model provides a first motor, a drive shaft, a first bevel gear, and a second bevel gear, so that the rotating rod can drive the two rotating drums and the cutting disc to rotate synchronously, so that the two cutting discs can synchronously cut the curb, and two slits can be cut at one time.

When the two slits of the curb are cut synchronously, the marking rod is placed in correspondence with the slits after cutting, so that the positions of subsequent cutting can be marked, ensuring that the intervals between the subsequent cutting points of the equipment are equal, so as to ensure that the spacing of the cutting slits of the overall curb after multiple cuttings is equidistant;

[0018] In summary, the utility model can realize the cutting processing of two slits at one time, which is more efficient than the traditional method of cutting one slit at a time, achieving twice the result with half the effort, and the synchronous cutting of the two slits is highly synchronized, the cutting effect is better, and the distance between the two cutting discs can be adjusted, and the curbstone can be flexibly cut into slits of different distances, thereby improving the versatility of the curbstone cutting processing. In addition, when the two slits of the curbstone are synchronously cut, the position of the subsequent cutting can be marked by placing the marking rod corresponding to the slit after cutting, ensuring that the intervals between the subsequent cutting points of the equipment are equal, so as to ensure that the cutting slits of the entire curbstone are equidistant after multiple cuttings.

[0023] The following combines specific implementation cases and the attached Figures 1 to 3 to further illustrate the present utility model, but the present utility model is not limited to these embodiments.

[0024] Refer to Figures 1 to 3 As shown, a curb cutting slot device includes a base 1, a mounting seat 2 is fixedly installed at the top of the base 1, a screw rod 3 is rotatably installed in the mounting seat 2 through a bearing, a second motor 21 is installed on the left side wall of the mounting seat 2, the output end of the second motor 21 is connected to the screw rod 3, the rotation of the second motor 21 drives the screw rod 3 to rotate, external threads with opposite directions are arranged on the left and right sides of the outer wall of the screw rod 3, a limiting rod 4 is fixedly installed in the mounting seat 2, and the limiting rod 4 is arranged parallel to the screw rod 3. A first moving seat 5 and a second moving seat 6 are slidably sleeved on the screw rod 3 and the limiting rod 4. The second moving seat 6 and the first moving seat 5 are symmetrically arranged with respect to the screw rod 3 left and right. The first moving seat 5 and the second moving seat 6 are respectively threadedly connected to the screw rod 3. The rotating screw rod 3 causes the first moving seat 5 and the second moving seat 6 to move symmetrically with respect to the screw rod 3. A fixed seat 7 is fixedly installed in the middle of the screw rod 3. When the first moving seat 5 and the second moving seat 6 move symmetrically with respect to the middle of the screw rod 3, that is, they move symmetrically with respect to the fixed seat 7, and the fixed seat 7 is fixedly connected to the mounting seat 2. Cutting units are respectively arranged on the front sides of the second moving seat 6 and the fixed seat 7. The two cutting units rotate synchronously for cutting processing, and the cutting of two slots is achieved at one time.

[0025] Refer to Figure 1 and Figure 3As shown in the figure, the cutting unit includes a driving assembly, and also includes two support rods 12 fixedly installed on the front side of the mounting base 2. A rotating rod 13 is rotatably connected between the two support rods 12 through bearings. The cutting unit further includes a supporting bracket 15. The front end of the supporting bracket 15 is rotatably provided with a rotating cylinder 16 through a bearing. A cutting disc 17 is fixedly installed on the outer wall of the rotating cylinder 16. When the rotating rod 13 rotates, it can drive the rotating cylinder 16 and the cutting disc 17 to rotate synchronously, realizing the synchronous cutting process of the two cutting discs 17. A positioning pin 18 is penetrated through the outer wall of the rotating cylinder 16. A plurality of jacks 19 are equidistantly arranged on the rotating rod 13 from left to right. The positioning pin 18 penetrates through the outer wall of the rotating cylinder 16 and is located in the inner cavity of one of the jacks 19. When it is necessary to adjust the cutting spacing of the two cutting discs 17, the positioning pins 18 on the outer walls of the two rotating cylinders 16 are respectively separated from the outer walls of the rotating cylinders 16. At this time, the rotating cylinder 16 is separated from the rotating rod 13 in terms of limit. Under the action of external force, the rotating cylinder 16 can move along the outer wall of the rotating rod 13. After adjusting the position, the positioning pin 18 is repositioned in the inner cavities of the rotating cylinder 16 and the jack 19, prompting the rotating cylinder 16 and the rotating rod 13 to form a stable connection, ensuring that when the rotating rod 13 rotates later, it can drive the rotating cylinder 16, the cutting disc 17, and the positioning pin 18 to rotate synchronously, realizing the cutting of the curbstone by the rotation of the cutting disc 17.

[0026] Refer to Figure 3 As shown in the figure, the driving assembly includes a mounting frame 8 fixedly installed on the front side of the mounting base 2. A first motor 9 is installed in the inner cavity of the mounting frame 8. The output end of the first motor 9 is connected with a driving shaft 10. A first bevel gear 11 is fixedly installed at the front end of the driving shaft 10. A second bevel gear 14 is fixedly installed on the outer wall of the rotating rod 13, and the first bevel gear 11 is meshed with the second bevel gear 14. By starting the first motor 9, the driving shaft 10 and the first bevel gear 11 are driven to rotate, so as to prompt the second bevel gear 14 and the rotating rod 13 to rotate synchronously. Driven by the rotating rod 13, the left and right rotating cylinders 16 and the cutting discs 17 at the corresponding positions rotate synchronously. At this time, the rotating cylinder 16, the cutting disc 17, and the positioning pin 18 rotate relative to the supporting bracket 15. Through the synchronous rotation of the left and right cutting discs 17, two gaps of the curbstone are cut at one time; specifically, the rotating rod 13 penetrates through the side wall of the mounting frame 8, and the rotating rod 13 is rotatably connected with the mounting frame 8 through a bearing, so as to ensure that the rotating rod 13 can rotate along the outer wall of the mounting frame 8, and at the same time ensure that the mounting frame 8 supports the rotating rod 13.

[0027] Refer to Figure 3As shown in the figure, the supporting bracket 15 on the left is fixedly connected to the front end of the second moving seat 6, and the supporting bracket 15 in the middle is fixedly connected to the front end of the fixed seat 7, so as to ensure that the second moving seat 6 can drive the supporting bracket 15 on the left and the cutting disc 17 on the left to move synchronously, and the fixed frame 7 can drive the supporting bracket 15 in the middle and the cutting disc 17 in the middle to move synchronously; in addition, a marking rod 20 is fixedly installed at the front end of the first moving seat 5, and the left cutting disc 17 and the marking rod 20 are symmetrically arranged left and right with respect to the middle cutting disc 17. By placing the marking rod 20 corresponding to the cut gap, the distance between the two cutting discs 17 is equal to the distance between the middle cutting disc 17 and the marking rod 20 at this time. This ensures that the intervals between subsequent cutting points of the equipment are equal, and the marking rod 20 can be used to mark the positions of subsequent cuts to ensure that the cutting gap intervals are equidistant after multiple cuts of the overall curbstone.

[0028] In addition, refer to Figure 1 As shown in the figure, a rear seat 22 is fixedly installed on the rear side wall of the base 1, a column 23 is fixedly installed at the top of the rear seat 22, and a handle 24 is fixedly installed at the top of the rear side wall of the column 23. By holding the handle 24 to drive the column 23, the rear seat 22 and the base 1 to move synchronously, the whole equipment can be moved to perform equidistant cutting seam processing along the curbstone.

[0029] It is worth noting that in this application, the first motor 9 and the second motor 21 adopt self-locking motors that can lock the output end commonly used in the market. When they are stopped, the output end can be self-locked and will not rotate under external force; there is no need to elaborate on the above existing components too much.

[0030] The working principle of a curbstone cutting seam device in this embodiment is as follows:

[0031] By starting the first motor 9 to drive the drive shaft 10 and the first bevel gear 11 to rotate, so as to prompt the second bevel gear 14 and the rotating rod 13 to rotate synchronously. Driven by the rotating rod 13, the left and right rotating cylinders 16 and the cutting discs 17 at the corresponding positions rotate synchronously. At this time, the rotating cylinders 16, the cutting discs 17, and the positioning pins 18 rotate relative to the supporting bracket 15. By the synchronous rotation of the left and right cutting discs 17, two gaps of the curbstone are cut and processed at one time.

[0032] When it is necessary to adjust the cutting spacing of the two cutting discs 17, the positioning pins 18 on the outer walls of the two rotating cylinders 16 are respectively disengaged from the outer walls of the rotating cylinders 16. At this time, the rotating cylinders 16 are disengaged from the limit of the rotating rods 13, and the rotating cylinders 16 under the action of external force can move along the outer walls of the rotating rods 13; by driving the screw rod 3 to rotate through the opened second motor 21, the second moving seats 6 and the first moving seats 5 on the left and right sides of the screw rod 3 are driven to move synchronously along the outer walls of the limiting rods 4, so as to drive the cutting disc 17 on the front side of the second moving seat 6 and the marking rod 20 on the front side of the first moving seat 5 to move synchronously towards the middle or towards both sides relative to the fixed seat 7. The movement of the left cutting disc 17 relative to the middle fixed seat 7 can realize the adjustment of the spacing between the two cutting discs 17 to meet the processing requirements of cutting different-spacing gaps in the curbstone; after adjusting the position, the positioning pin 18 is repositioned in the inner cavities of the rotating cylinder 16 and the jack 19, so as to promote the stable connection between the rotating cylinder 16 and the rotating rod 13, and ensure that the rotating rod 13 can drive the rotating cylinder 16, the cutting disc 17, and the positioning pin 18 to rotate synchronously when rotating later, so as to realize the cutting of the curbstone by the rotation of the cutting disc 17;

[0033] Since the second moving seat 6 and the first moving seat 5 are symmetric about the fixed seat 7, the left cutting disc 17 and the right marking rod 20 after adjustment are symmetric about the middle cutting disc 17. When synchronously cutting two gaps in the curbstone, by placing the marking rod 20 corresponding to the cut gap, the spacing between the two cutting discs 17 is equal to the spacing between the middle cutting disc 17 and the marking rod 20 at this time. Thus, it is ensured that the intervals between the subsequent cutting points of the equipment are equal, and the marking rod 20 can mark the positions of subsequent cuts to ensure that the cutting gap intervals are equidistant after multiple cuts of the overall curbstone;

[0034] The utility model can realize the cutting process of two gaps at one time, which is more efficient than the traditional method of cutting one gap at a time, achieving twice the result with half the effort. Moreover, the synchronous cutting of the two gaps has strong synchronism and better cutting effect. In addition, the spacing between the two cutting discs 17 can be adjusted, and the curbstone can be flexibly cut into gaps with different spacings, improving the versatility of the curbstone cutting process. In addition, when synchronously cutting two gaps in the curbstone, by placing the marking rod 20 corresponding to the cut gap, the positions of subsequent cuts can be marked, ensuring that the intervals between the subsequent cutting points of the equipment are equal, so as to ensure that the cutting gap intervals are equidistant after multiple cuts of the overall curbstone.

[0035] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
