Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of road cutting machines, in particular to a road repair cutting machine. Background Art
[0002] With the acceleration of urbanization and the continuous development of infrastructure construction, road maintenance and construction work are becoming more and more frequent. In the process of road construction and maintenance, road cutting machines play a vital role.
[0003] Traditional road repair operations use manual cutters and large-scale machinery. However, these traditional methods suffer from low efficiency, high labor intensity, and poor safety. Manual cutters, while flexible, require high operator skill and are labor-intensive, which can easily lead to fatigue and injury. Large-scale machinery, while efficient, is bulky and complex to operate, making it unsuitable for confined or complex work environments.
[0004] However, in actual use, due to the complex road conditions, large or small road cutting machines need to be used to cut the road surface according to different road conditions. In addition, existing cutting equipment, whether large or small, mostly uses saw blades to cut the road surface. However, the safety hazards of rotating saw blades are high during use, so reciprocating saw blades are used. However, the reciprocating saw blades lead to a low saw blade utilization rate, severe wear on the bottom, and technical problems such as being unable to be used in other places.
[0005] Therefore, the utility model proposes a road surface repair and cutting machine. Utility Model Content
[0006] The purpose of the utility model is to solve the shortcomings of the prior art and to provide a road surface repair and cutting machine.
[0007] In order to achieve the above-mentioned object, the present invention adopts the following technical solution: a road surface repair and cutting machine, comprising a moving mechanism, a lifting seat is provided on the moving mechanism, a lifting frame is provided on the lifting seat, a mounting assembly is provided on the lifting seat, and a cutting assembly is provided on the mounting assembly;
[0008] The mounting assembly includes a connecting frame, which is connected to a lifting frame. An upper lifting frame is provided on the top of the connecting frame, and an adjusting frame is provided on the other side of the connecting frame. A lifting gear is rotatably connected to the upper lifting frame. The connecting frame and the adjusting frame are both rotatably connected to a limiting gear and a driving gear, and the limiting gear is located above the driving gear.
[0009] As a preferred embodiment, first electric push rods are provided on both sides of the upper lifting frame, and output ends of the first electric push rods are connected to the connecting frame.
[0010] The beneficial effect of adopting the above further scheme is: under the action of the first electric push rod, it is used to adjust the position of the upper lifting frame. When in use, the first electric push rod is turned on, so that the first electric push rod applies a downward thrust, driving the upper lifting frame to move upward, thereby changing the working state of the chain cutting saw.
[0011] As a preferred embodiment, a second electric push rod is provided at one end of the connecting frame close to the lower limit frame, and an output end of the second electric push rod is connected to the adjustment frame.
[0012] The beneficial effect of adopting the above further scheme is: under the action of the second electric push rod, it is used to adjust the position of the adjustment frame. When in use, the second electric push rod is turned on, so that the second electric push rod applies thrust to one side, thereby driving the adjustment frame to move left and right, changing the working state of the chain cutting saw.
[0013] As a preferred embodiment, the cutting assembly includes a chain cutting saw, and the chain cutting saw is meshedly connected with the lifting gear, the limiting gear and the driving gear.
[0014] The beneficial effect of adopting the above-mentioned further scheme is: the road surface is cut by a chain cutting saw instead of a saw blade. During actual use, the chain cutting saw rotates in the installation assembly by rotating the lifting gear, the limit gear and the driving gear. Under the action of the chain cutting saw, the road surface is cut by the saw teeth arranged on the surface.
[0015] As a preferred embodiment, a first limit guard plate is provided on both sides of the lifting gear in the upper lifting frame, and a second limit guard plate and a third limit guard plate are provided on both sides of the limit gear and the driving gear on the connecting frame and the adjusting frame. The second limit guard plate is provided on both sides of the limit gear, and the third limit guard plate is provided on both sides of the driving gear.
[0016] The beneficial effect of adopting the above further scheme is: by setting the first limit guard plate, the second limit guard plate and the third limit guard plate, the chain cutting saw is limited to prevent the chain cutting saw from separating from the lifting gear, the limit gear and the driving gear during rotation, causing the cutting work to be suspended.
[0017] As a preferred embodiment, a driving motor is provided on a side of the adjustment frame close to the driving gear, and an output end of the driving motor is connected to the driving gear.
[0018] The beneficial effect of adopting the above further scheme is: by setting the first limit guard plate, the second limit guard plate and the third limit guard plate, the chain cutting saw is limited to prevent the chain cutting saw from separating from the lifting gear, the limit gear and the driving gear during rotation, causing the cutting work to be suspended.
[0019] As a preferred embodiment, the chain cutting saw is sleeved on the outside of the lifting gear and the two driving gears.
[0020] The beneficial effect of adopting the above-mentioned further scheme is: by setting the lifting gear and the driving gear, the cutting shape of the chain cutting saw is changed. When the lifting gear moves upward, the driving gear is controlled to retract inward, so that the cutting length of the chain cutting saw is reduced. When the lifting gear moves downward, the driving gear is controlled to move to both sides, so that the cutting length of the chain cutting saw is increased.
[0021] As a preferred embodiment, a lower limit frame is provided at the bottom of the connecting frame, and a tooth groove is provided at the bottom of the lower limit frame, and the tooth groove is engaged with the chain cutting saw.
[0022] The beneficial effect of adopting the above further solution is: under the action of the lower limit frame, the chain cutting saw between the two driving gears is auxiliary supported to avoid the chain cutting saw from moving upward due to excessive cutting length, which cannot fully contact the ground and reduces the cutting effect.
[0023] Compared with the prior art, the advantages and positive effects of the present invention are:
[0024] 1. In the utility model, when in use, the first electric push rod and the second electric push rod are turned on at the same time as needed. Under the action of the first electric push rod, the upper lifting frame is driven to move upward, and at the same time, the second electric push rod is controlled to drive the adjusting frame to move inward, so that the length of the bottom of the chain cutting saw is reduced, and a small range of cutting work is performed. When in use, the first electric push rod can be controlled to drive the upper lifting frame to move downward, and at the same time, the second electric push rod is controlled to drive the adjusting frame to move to both sides, so that the length of the bottom of the chain cutting saw is increased, thereby changing the cutting range of the device and improving work efficiency.
[0025] 2. In the present invention, a chain cutting saw is used to cut the road surface instead of a saw blade. The advantage of the chain cutting saw design is that traditional rotary saw blades or reciprocating saw blades cannot avoid saw blade wear or even breakage. When a saw blade breaks, a new saw blade can only be replaced to carry out the cutting process. However, the design of the chain cutting saw not only improves the cutting flexibility during use, but also when the chain cutting saw breaks, only the damaged section of the chain cutting saw needs to be replaced, thereby reducing maintenance costs.

[0036] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.
[0037] Example 1
[0038] like Figure 1-6As shown, the utility model provides a technical solution: a road repair and cutting machine, including a moving mechanism 1, a lifting seat 11 is provided on the moving mechanism 1, a lifting frame 12 is provided on the lifting seat 11, a mounting assembly 2 is provided on the lifting seat 11, and a cutting assembly 3 is provided on the mounting assembly 2. The modification is moved to a designated position by the moving mechanism 1. It is more time-saving and labor-saving to use the moving mechanism 1 instead of manual movement. Under the action of the lifting seat 11, the lifting frame 12 is driven to move up and down. When the moving mechanism 1 is moving, the lifting frame 12 can be driven to lift up by the lifting seat 11 to avoid contact between the cutting assembly 3 and the ground. When performing cutting work, the lifting seat 11 is controlled to drive the lifting frame 12 to move downward, so that the cutting assembly 3 contacts the ground to perform cutting work.
[0039] like Figure 4 - Figure 5 As shown, the mounting assembly 2 includes a connecting frame 22, which is connected to the lifting frame 12. An upper lifting frame 21 is provided on the top of the connecting frame 22, and an adjusting frame 24 is provided on the other side of the connecting frame 22. A lifting gear 32 is rotatably connected to the upper lifting frame 21. The connecting frame 22 and the adjusting frame 24 are both rotatably connected to a limiting gear 33 and a driving gear 34. The limiting gear 33 is located above the driving gear 34.
[0040] like Figure 4 - Figure 5 As shown, a first electric push rod 211 is provided on both sides of the upper lifting frame 21. The output end of the first electric push rod 211 is connected to the connecting frame 22. Under the action of the first electric push rod 211, the position of the upper lifting frame 21 is adjusted. When in use, the first electric push rod 211 is turned on, so that the first electric push rod 211 applies a thrust downward, driving the upper lifting frame 21 to move upward, thereby changing the working state of the chain cutting saw 31.
[0041] like Figure 4 - Figure 5 As shown, a second electric push rod 232 is provided at one end of the connecting frame 22 close to the lower limit frame 23, and the output end of the second electric push rod 232 is connected to the adjusting frame 24. Under the action of the second electric push rod 232, the position of the adjusting frame 24 is adjusted. When in use, the second electric push rod 232 is turned on, so that the second electric push rod 232 applies a thrust to one side, thereby driving the adjusting frame 24 to move left and right, thereby changing the working state of the chain cutting saw 31.
[0042] like Figure 6As shown, a first limiting guard plate 321 is provided on both sides of the lifting gear 32 in the upper lifting frame 21, and a second limiting guard plate 331 and a third limiting guard plate 341 are provided on both sides of the limiting gear 33 and the driving gear 34 on the connecting frame 22 and the adjusting frame 24. The second limiting guard plate 331 is provided on both sides of the limiting gear 33, and the third limiting guard plate 341 is provided on both sides of the driving gear 34. By setting the first limiting guard plate 321, the second limiting guard plate 331 and the third limiting guard plate 341, the chain cutting saw 31 is limited to prevent the chain cutting saw 31 from separating from the lifting gear 32, the limiting gear 33 and the driving gear 34 during rotation, causing the cutting work to be suspended.
[0043] When in use, the first electric push rod 211 and the second electric push rod 232 are turned on at the same time as needed. Under the action of the first electric push rod 211, the upper lifting frame 21 is driven to move upward. At the same time, the second electric push rod 232 is controlled to drive the adjustment frame 24 to move inward, so that the length of the bottom of the chain cutting saw 31 is reduced, and a small range of cutting work is performed. When in use, the first electric push rod 211 can be controlled to drive the upper lifting frame 21 to move downward. At the same time, the second electric push rod 232 is controlled to drive the adjustment frame 24 to move to both sides, so that the length of the bottom of the chain cutting saw 31 is increased, thereby changing the cutting range of the device and improving work efficiency.
[0044] Example 2
[0045] like Figure 4 - Figure 6 As shown, the cutting assembly 3 includes a chain cutting saw 31, which is meshedly connected with a lifting gear 32, a limiting gear 33 and a driving gear 34. The chain cutting saw 31 is used to cut the road surface instead of a saw blade. In actual use, the lifting gear 32, the limiting gear 33 and the driving gear 34 are rotated to make the chain cutting saw 31 rotate in the mounting assembly 2. Under the action of the chain cutting saw 31, the road surface is cut by the saw teeth arranged on the surface.
[0046] The chain cutting saw 31 is sleeved on the outside of the lifting gear 32 and the two driving gears 34. The cutting mode of the chain cutting saw 31 is changed by the setting of the lifting gear 32 and the driving gear 34. When the lifting gear 32 moves upward, the driving gear 34 is controlled to retract inward, so that the cutting length of the chain cutting saw 31 is reduced. When the lifting gear 32 moves downward, the driving gear 34 is controlled to move to both sides, so that the cutting length of the chain cutting saw 31 is increased.
[0047] like Figure 4As shown, a driving motor 241 is provided on one side of the adjusting frame 24 close to the driving gear 34, and the output end of the driving motor 241 is connected to the driving gear 34. The chain cutting saw 31 is limited by the setting of the first limiting guard plate 321, the second limiting guard plate 331 and the third limiting guard plate 341 to prevent the chain cutting saw 31 from being separated from the lifting gear 32, the limiting gear 33 and the driving gear 34 during the rotation, causing the cutting work to be suspended.
[0048] like Figure 4-Figure 6 As shown, the chain cutting saw 31 is sleeved on the outside of the lifting gear 32 and the two driving gears 34. The cutting mode of the chain cutting saw 31 is changed by setting the lifting gear 32 and the driving gear 34. When the lifting gear 32 moves upward, the driving gear 34 is controlled to retract inward, so that the cutting length of the chain cutting saw 31 is reduced. When the lifting gear 32 moves downward, the driving gear 34 is controlled to move to both sides, so that the cutting length of the chain cutting saw 31 is increased.
[0049] like Figure 5 As shown, a lower limit frame 23 is provided at the bottom of the connecting frame 22, and a tooth groove 231 is provided at the bottom of the lower limit frame 23. The tooth groove 231 is meshed and connected with the chain cutting saw 31. Under the action of the lower limit frame 23, the chain cutting saw 31 in a section between the two driving gears 34 is auxiliary supported to avoid the chain cutting saw 31 from moving upward due to excessive cutting length, and unable to fully contact the ground, resulting in reduced cutting effect.
[0050] The chain cutting saw 31 is set up to replace the saw blade for cutting the road surface. The advantage of the chain cutting saw 31 design is that traditional rotary saw blades or reciprocating saw blades cannot avoid saw blade wear or even breakage. When the saw blade breaks, it can only be replaced with a new saw blade to carry out the cutting process. However, the design of the chain cutting saw 31 not only improves the cutting flexibility during use, but also when the chain cutting saw 31 breaks, it only needs to replace the damaged section of the chain cutting saw 31, thereby reducing maintenance costs.
[0051] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
