Description

Technical Field

[0001] The utility model relates to the field of construction machinery, in particular to a cutting device for chamfering the edges of curb stones into rounded corners. Background Art

[0002] Curb stones are transported to the construction site in a prefabricated manner. However, the chamfers of prefabricated curb stones often have inconsistent sizes. After installation, the appearance quality of the curb stones is affected due to the inconsistent chamfer sizes. Generally, it is necessary to use a cutting device for curb stones to perform on-site secondary processing to improve their aesthetics.

[0003] The patent with the publication number CN220972877U discloses a cutting device for chamfering curb stones. A vertical strip-shaped groove is provided on a support frame. By adjusting an adjusting bolt and an adjusting nut, an installation frame moves up and down in the strip-shaped groove. Installation plates are vertically arranged on both sides of the installation frame. A sliding screw rod passes through the installation plates. A cutting machine is arranged on the sliding screw rod. The sliding screw rod is locked on the installation plates through a sliding nut. A locking screw rod penetrating the installation frame is arranged on the back side of the cutting machine. Locking nuts are threadedly connected to both sides of the installation frame on the locking screw rod. And a kidney-shaped hole for the transverse sliding of the locking screw rod is provided on the installation frame to realize the adjustment of the inclination degree of the cutting machine. Since the position of the cutting machine is fixed during use and cannot be adjusted during implementation, the cutting angle can only be adjusted when the equipment is shut down. When the cutting device is pushed to cut the outer corner of the curb stone, the outer corner of the curb stone can only be cut into an inclined plane and cannot be cut into a rounded corner.

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0028] Referring to Figures 1-5 , the present invention provides a cutting device for chamfering the edges of a curbstone, including a support frame 1, a clamping structure 2, a cutting machine 3, an arc slider mechanism 4, a driving component 5, a connecting block 6, a water tank groove 7, a water tank 8, a connecting pipe 9, a nozzle 10, a support rod 11, a support pulley 12, a handrail 13, and a top surface pulley 14.

[0029] Specifically, a clamping structure 2 is installed at the lower end of the support frame 1. The clamping structure 2 is used for sliding and clamping on the two side walls of the curbstone to stabilize the curbstone during on-site construction. The support frame 1 is provided with an arc slider mechanism 4 and a driving component 5. The arc slider mechanism 4 includes an arc chute 41 installed on the support frame 1 and a limiting slider 42 slidably connected in the arc chute 41. The concave surface of the arc chute 41 faces a top edge of the curbstone. The limiting slider 42 is fixedly connected to the cutting machine 3 through a connecting block 6. The cutting machine 3 is used for chamfering a top edge of the curbstone, and the driving component 5 is used for driving the limiting slider 42 to reciprocate along the arc chute 41.

[0030] The driving component 5 includes a fixing plate 51, a driving motor 52 and a driving rod 53. The fixing plate 51 is fixedly connected to the support frame 1 and is used for fixedly installing the driving motor 52. The output shaft of the driving motor 52 is in transmission connection with one end of the driving rod 53, and the other end of the driving rod 53 is rotatably connected to the limit slider 42.

[0031] The driving rod 53 includes a first driving rod 531, a second driving rod 532 and a third driving rod 533. The upper end of the first driving rod 531 is rotatably connected to the limit slider 42 through a rotating shaft, and the limit slider 42 is fixedly connected to the connecting block 6 through a rotating shaft. The lower end of the first driving rod 531 is rotatably connected to the upper end of the third driving rod 533. The lower end of the third driving rod 533 is in transmission connection with the output shaft of the driving motor 52. The upper end of the second driving rod 532 is fixedly connected to the lower end of the arc-shaped chute 41, and the lower end of the second driving rod 532 is rotatably connected to the lower end of the third driving rod 533. During use, the output shaft of the driving motor 52 drives the third driving rod 533 to rotate, so that the first driving rod 531 rotatably connected to the third driving rod 533 drives the limit slider 42 to slide repeatedly in the arc-shaped chute 41 through the rotating shaft. While the limit slider 42 slides repeatedly in the arc-shaped chute 41, it drives the connecting block 6 connected by fixation to slide, and in addition, the cutting machine 3 fixedly connected to the connecting block 6 forms an arc-shaped movement track.

[0032] The clamping structure 2 includes a limit component 21 and a fixing component 22. The limit component 21 is fixedly and slidably connected to one end of the support frame 1, and the fixing component 22 is fixedly connected to the other end of the support frame 1. The limit component 21 and the fixing component 22 are arranged oppositely and are respectively used for clamping the two side walls of the curbstone, so as to improve the stability of the curbstone during the cutting process.

[0033] The limit component 21 includes a limit plate 211, a limit rod 212 and a limit groove 213. The limit grooves 213 are arranged in the horizontal direction on the front and rear sides of one end of the support frame 1. The limit plate 211 is fixedly slid on the limit grooves 213 through the limit rod 212. During use, the limit plate 211 is pushed to move the curbstone to directly below the cutting machine 3, and the limit plate 211 is fixed on the limit grooves 213 through the limit rod 212 to limit the sliding of the limit plate 211 on the limit grooves 213.

[0034] In an embodiment of the present utility model, the limit rod 212 is a bolt, and the limit rod 212 is in threaded connection with the limit plate 211. By screwing the limit rod 212, the fixed or sliding connection mode between the limit rod 212 and the limit groove 213 can be realized.

[0035] The fixing assembly 22 includes a fixing rod 221, a fixing sleeve 222, a spring 223 and a side roller 224. A spring 223 is arranged inside the fixing sleeve 222. Both ends of the spring 223 are fixedly connected to the bottom of the inner wall of the fixing sleeve 222 and the fixing rod 221 respectively. The other end of the support frame 1 is fixedly connected to the fixing sleeve 222. The end of the fixing sleeve 222 away from the support frame 1 is slidably sleeved on the surrounding side of one end of the fixing rod 221. The other end of the fixing rod 221 is connected to the side roller 224. The side roller 224 is used to be slidably connected to the side wall of one side of the curb. When the curb passes through the limited space of the support frame 1, the limiting assembly 21 and the fixing assembly 22, the fixing rod 221 is moved to drive the spring 223 compressed in the fixing sleeve 222 to press the side roller 224 against the side of the curb. During the cutting process, the curb can reduce the friction of the cutting equipment.

[0036] A number of support rods 11 and support pulleys 12 are arranged in parallel in the horizontal direction between the limit plate 211 and the curb. The two ends of the support rod 11 are respectively connected to the limit plate 211 and the support pulley 12, and the support pulley 12 is slidably connected to the other side wall of the curb. During use, when the cutting equipment turns and encounters a curved curb, the support pulley 12 is tangent to the inner wall of the curved curb. The pressure applied to the side roller 224 through the curved curb changes the length of the fixing spring 223 of the fixing rod 221, so that the cutting equipment can pass smoothly.

[0037] A plurality of top pulleys 14 are arranged at the bottom of the support frame 1 to reduce the friction between the support frame 1 and the curb. The top pulley 14 is used for sliding connection with the top surface of the curb. A water tank groove 7 is arranged on the top of the support frame 1. A water tank 8 is arranged in the water tank groove 7. The water tank 8 is connected to a nozzle 10 through a connecting pipe 9. A valve (not shown in the figure) is arranged on the connecting pipe 9. The nozzle 10 is arranged toward the cutting machine 3. When cutting the outer corners of the curb, the nozzle 10 sprays water in the water tank 8 in the direction of the cutting machine 3 to avoid the flying of dust.

[0038] The side wall of the water tank 7 is provided with a handrail 13 for conveniently pushing the cutting device.
