Description

Technical Field

[0001] The invention relates to the technical field of road construction equipment, and in particular to a seam cutting device for traffic road construction. Background Art

[0002] In the construction and maintenance of roads, when the former is built with concrete as the raw material, due to the characteristics of concrete expansion and contraction due to heat, it is necessary to use a cutting device to cut the concrete before it is completely cooled down to avoid cracking of the concrete after cooling. On the other hand, in the daily maintenance of road cracks, it is also necessary to use a cutting device to cut the cracks and repair them.

[0003] A slitting device for road and bridge construction is disclosed in Chinese patent publication number CN118257186B. The slitting device for road and bridge construction can freely retract and extend the sawtooth blade through a retracting mechanism. When slitting is required, the sawtooth blade is lowered and the second motor is started. The output shaft of the second motor drives the two sawtooth blades to rotate. The worker pushes the handle to move the entire device along the route required for slitting, thereby achieving the effect of the sawtooth blade easily cutting two slits at one time.

[0004] However, compared with the existing technologies in the related fields, firstly, the cutting saw blade is prone to sudden jamming during cutting. When the saw blade suddenly jams, the motor may encounter a sudden increase in load. If the motor does not have proper overload protection measures, this may cause the motor to overheat or even be damaged, thereby shortening its service life. At the same time, the suddenly jammed saw blade may generate additional mechanical stress on the motor shaft, which may cause premature wear or damage to the bearing; secondly, when the saw blade is stuck, it cannot be pulled out quickly for emergency treatment. If it is pulled out hard by dragging, it is easy to cause the saw blade to break, making it difficult to remove the broken saw blade from the cut subsequently. Summary of the invention

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] An embodiment of a cutting device for traffic road construction of the present invention is as follows Figures 1 to 14 As shown, it includes a mobile vehicle 1, a transmission shaft 2 is rotatably provided on the side of the front end of the mobile vehicle 1, a rotation hole is opened at the position of the mobile vehicle 1 corresponding to the transmission shaft 2, and the transmission shaft 2 is connected with the rotation hole through a bearing. By using the above-mentioned bearing, the friction force when the transmission shaft 2 rotates can be reduced, and the stability of the transmission shaft 2 when it rotates can be improved. A driving component 3 for controlling the rotation of the transmission shaft 2 is provided on the top of the mobile vehicle 1, a control box 4 is provided at the top near the rear end of the mobile vehicle 1, a handle is fixedly installed at the rear of the control box 4, and a support component 5 for controlling the tilting of the front end of the mobile vehicle 1 is provided on the control box 4, a protective cover 6 is fixedly installed on the side of the mobile vehicle 1 close to the transmission shaft 2, a follower shaft 7 is rotatably provided inside the protective cover 6, a rotation hole is opened at the position of the protective cover 6 corresponding to the follower shaft 7, and the follower shaft 7 is matched with the rotation hole through a bearing. The above-mentioned bearing is used for connection, and the friction force of the follower shaft 7 during rotation can be reduced, and the stability of the follower shaft 7 during rotation can be improved. An emergency separation component 8 is provided at one end of the follower shaft 7 close to the transmission shaft 2, and an engagement transmission component 9 is provided at one end of the transmission shaft 2 close to the follower shaft 7. A mounting disk 10 is fixedly provided on the outer surface of the follower shaft 7, and a saw blade 11 is fixedly installed on the mounting disk 10. The engagement transmission component 9 is slidably matched with the transmission shaft 2 through an elastic sliding component 12. During cutting, the engagement transmission component 9 is engaged with the emergency separation component 8, so that the transmission shaft 2 drives the follower shaft 7 to rotate and the saw blade 11 cuts the road surface. When the saw blade 11 is stuck, the resistance encountered by the saw blade 11 increases rapidly, and the emergency separation component 8 is used to absorb the rapidly increasing resistance and cause the engagement transmission component 9 to separate from it, so that the transmission shaft 2 rotates alone.

[0035] like Fig.11 As shown, the emergency separation assembly 8 includes an inner plate 801 fixedly arranged on the outer surface of the follower shaft 7, the follower shaft 7 is located on the outer surface of the inner plate 801 and is covered with a shell 802, the shell 802 is rotatably matched with the follower shaft 7, and a plurality of movable grooves 803 are provided at both ends of the shell 802, and movable blocks 804 are fixedly arranged inside the inner plate 801 corresponding to the plurality of movable grooves 803, and the movable blocks 804 are connected with the movable grooves 803 through the first elastic member 805, as shown in FIG. Figures 4 to 12 As shown, the first elastic member 805 is an elliptical spring. When the saw blade 11 is stuck, the resistance encountered by the saw blade 11 will increase rapidly, and then the movable block 804 will squeeze the first elastic member 805 (elliptical spring) and then move inside the movable groove 803, thereby causing the first elastic member 805 (elliptical spring) to deform. When the first elastic member 805 (elliptical spring) is deformed, its middle part will expand outward.

[0036] like Fig.13As shown, the meshing transmission assembly 9 includes a moving plate 901 slidably arranged on the outer surface of the transmission shaft 2, a plurality of meshing blocks 902 are fixedly arranged at one end of the moving plate 901 close to the housing 802, the housing 802 is provided with meshing grooves 806 at positions corresponding to the plurality of meshing blocks 902, the housing 802 is provided with convex grooves 807 between the plurality of meshing grooves 806, and a plurality of convex grooves 807 are fixedly provided with a plurality of convex blocks, such as Figures 4 to 14 As shown, by utilizing the cooperation between the engagement block 902 and the engagement groove 806, the outer shell 802 can drive the inner disk 801 and the follower shaft 7 to rotate. When the follower shaft 7 rotates, the mounting disk 10 will drive the saw blade 11 to rotate, and the outward expansion force of the first elastic member 805 (elliptical spring) is utilized to push the movable disk 901, so that the engagement block 902 is separated from the engagement groove 806, and then the engagement block 902 will move inside the protrusion groove 807, thereby achieving the purpose of quickly cutting off the connection between the emergency separation component 8 and the engagement transmission component 9, and realizing that the saw blade 11 can be quickly stopped after being stuck.

[0037] like Fig.14 As shown, the elastic sliding assembly 12 includes a slider 1201 fixedly arranged on the inner wall of the moving plate 901, a slide groove 1202 is provided at a position of the transmission shaft 2 corresponding to the slider 1201, and the slider 1201 and the slide groove 1202 are connected by a second elastic member 1203. There are multiple elastic sliding assemblies 12, and multiple elastic sliding assemblies 12 are arranged in a circular array on the outer surface of the transmission shaft 2, such as Figures 5 to 13 As shown, the second elastic member 1203 is a compression spring. When the movable disk 901 slides, the slider 1201 will squeeze the second elastic member 1203 and slide inside the slide groove 1202. At the same time, when the slider 1201 slides inside the slide groove 1202, the transmission shaft 2 can still drive the movable disk 901 to rotate. When the saw blade 11 is freed, the squeezed second elastic member 1203 will continue to push the slider 1201. Therefore, when the engaging block 902 corresponds to the engaging groove 806, the elastic force of the second elastic member 1203 is used to make the slider 1201 drive the movable disk 901 to slide to one side of the housing 802, and the engaging block 902 will enter the engaging groove 806 again, so that the saw blade 11 can continue to cut the road surface.

[0038] like Figures 2 to 13As shown, the driving component 3 includes a motor 301 fixedly mounted on the top of the mobile vehicle 1, a driving wheel 302 is fixedly mounted on the output end of the motor 301, a driven wheel 303 is fixedly mounted on the outer surface of the transmission shaft 2 corresponding to the position of the driving wheel 302, the driving wheel 302 and the driven wheel 303 are connected by a transmission belt 304, and a first accommodating groove 101 is opened at the position of the mobile vehicle 1 corresponding to the transmission belt 304, by starting the motor 301, and then the driven wheel 303 is driven to rotate by the driving wheel 302 and the transmission belt 304, and then the driven wheel 303 will drive the transmission shaft 2 to rotate, and at this time, the elastic sliding component 12 can be used to allow the movable disk 901 to rotate with the transmission shaft 2, and at the same time, the outer shell 802 drives the inner disk 801 and the driven shaft 7 to rotate by the cooperation between the meshing block 902 and the meshing groove 806, and when the driven shaft 7 rotates, the mounting disk 10 drives the saw blade 11 to rotate.

[0039] like Figure 1 , Figure 3 and Figure 4 As shown, the support assembly 5 includes a support arm 501 hinged to the control box 4, and a support wheel 502 is rotatably provided at one end of the support arm 501 away from the control box 4. The control box 4 is located above the support arm 501 and is hinged with an electric push rod 503. The output end of the electric push rod 503 is hinged to the support arm 501, and the position of the mobile vehicle 1 corresponding to the support arm 501 is provided with a second accommodating groove 102. The support arm 501 is gradually retracted by the electric push rod 503, so that the saw blade 11 can slowly cut into the inside of the road, and the support arm 501 is pushed out by the electric push rod 503, so that the support wheel 502 contacts the ground, so that the front end of the mobile vehicle 1 is tilted, and the tilting of the front end of the mobile vehicle 1 is used to increase the distance between the saw blade 11 and the ground, and then the mobile vehicle 1 can be pushed to the specified position through the handle at the rear of the control box 4, and then it can be prepared to cut the road.

[0040] A storage battery is arranged inside the control box 4, and the storage battery can be used to supply power to the motor 301 and the electric push rod 503, so that the device does not need to be connected to external wires when in use.

[0041] The mobile vehicle 1, control box 4, battery, motor 301 and electric push rod 503 described in this application are well-known technologies in the technical field, so their working principles and detailed structures are not described. They are only described here without imposing any limitations.

[0042] The working process is as follows:

[0043] S1, such as Figure 1 and Figure 4 As shown, when in use, the mobile vehicle 1 is pushed to a designated position through the handle at the rear of the control box 4, and then the road can be prepared for cutting;

[0044] S2, such as Figures 1 to 4As shown, when cutting, the motor 301 is started first, and then the driven wheel 303 is driven to rotate through the driving wheel 302 and the transmission belt 304, and then the driven wheel 303 drives the transmission shaft 2 to rotate, as shown in FIG. Figures 7 to 14 As shown, the elastic sliding assembly 12 is used to allow the movable disk 901 to rotate along with the transmission shaft 2, and the outer shell 802 drives the inner disk 801 and the follower shaft 7 to rotate by the cooperation between the engagement block 902 and the engagement groove 806. When the follower shaft 7 rotates, the mounting disk 10 drives the saw blade 11 to rotate;

[0045] S3, such as Figure 3 and Figure 4 As shown, the arm 501 is gradually retracted by the electric push rod 503, and the saw blade 11 is slowly cut into the road. When the saw blade 11 cuts into the road, there will be a certain resistance of the saw blade 11, such as Figures 5 to 11 As shown, the saw blade 11 will then transmit resistance to the inner disk 801, so that the inner disk 801 rotates a certain degree inside the outer shell 802, and the movable block 804 will compress the first elastic member 805 (that is, compress the elliptical spring, and the expansion amount of the elliptical spring during daily cutting is more than half);

[0046] S4, such as Figures 4 to 13 As shown, when the saw blade 11 is stuck, the resistance to the saw blade 11 will increase rapidly, and then the movable block 804 will squeeze the first elastic member 805 (elliptical spring) and then move inside the movable groove 803, thereby causing the first elastic member 805 (elliptical spring) to deform. When the first elastic member 805 (elliptical spring) is deformed, its middle part will expand outward, and then the outward expansion force of the first elastic member 805 (elliptical spring) will be used to push the movable disk 901, so that the meshing block 902 is separated from the meshing groove 806, and then the meshing block 902 will move inside the protruding block groove 807, so as to achieve the purpose of quickly cutting off the connection between the emergency separation component 8 and the meshing transmission component 9, so that the saw blade 11 can be quickly stopped after being stuck. Figure 2 As shown, the protection of the motor 301 is achieved;

[0047] S5, such as Fig.14 As described above, when the moving plate 901 slides, the slider 1201 will squeeze the second elastic member 1203 and slide inside the slide groove 1202. At the same time, when the slider 1201 slides inside the slide groove 1202, the transmission shaft 2 can still drive the moving plate 901 to rotate;

[0048] S6, such as Figures 4 to 13As shown, when the engagement block 902 is separated from the engagement groove 806, the force of the first elastic member 805 (elliptical spring) to reset can cause the saw blade 11 to reverse, and the saw blade 11 will generate an outward thrust when it reverses, so that it has a certain ability to escape from trouble. At the same time, when the engagement block 902 moves inside the convex block groove 807, it will cause the outer shell 802 and the inner disk 801 to shake, thereby further improving the ability of the saw blade 11 to escape from trouble, so that the saw blade 11 can completely escape from trouble.

[0049] S7, such as Figures 3 to 14 As shown, after the saw blade 11 is freed, the squeezed second elastic member 1203 will continue to push the slider 1201, so that when the engagement block 902 corresponds to the engagement groove 806, the elastic force of the second elastic member 1203 allows the slider 1201 to drive the movable disk 901 to slide toward one side of the housing 802, and allows the engagement block 902 to enter the engagement groove 806 again, so that the saw blade 11 can continue to cut the road surface.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
