Abstract
Description
Technical Field
[0001] The invention belongs to the field of concrete seam cutting, and in particular relates to an automatic seam cutting machine for a chain track concrete inclined surface. Background Art
[0002] The concrete cutting machine is a vital mechanical equipment in cement pavement construction. It is mainly used to cut the expansion joints of concrete pavements to ensure the strength and life of the pavement. It mainly includes a mobile device and a cutting device. The mobile device generally rolls forward through a self-propelled device.
[0003] In engineering construction projects such as large canal slopes, highways, airport runways, and rural road slope protection, slope concrete cutting construction is hindered by site limitations and the particularity of the construction surface. It makes it difficult for traditional self-propelled cutting machines to move straight on the slope, or it increases costs to control its direction of travel. Summary of the invention
[0004] The purpose of the present invention is to provide a chain track concrete inclined surface automatic seam cutting machine in order to solve the above-mentioned problems.
[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:
[0006] A chain track concrete slope automatic seam cutting machine comprises a guide rail, a moving device movably arranged on the guide rail, a seam cutting device arranged on the moving device, and a cooling assembly for supplying water to the seam cutting device. A chain is arranged on the guide rail, wherein the moving device comprises a shell, a driving part arranged in the shell, the shaft of the driving part is provided with a sprocket engaged with the chain, and the seam cutting device comprises a shell and a cutting machine, and the shell is lifted and lowered on the shell.
[0007] As a further optimization scheme of the present invention, a rail groove is arranged on the inner side of the guide rail, wherein an L-shaped arm is arranged below the shell, and a guide wheel rollingly connected to the rail groove is arranged at the end of the L-shaped arm, and the guide wheels have at least two groups. This scheme limits the moving direction of the mobile device by arranging a rail groove on the inner side of the guide rail and by at least two groups of guide wheels, i.e., four guide wheels.
[0008] As a further optimization scheme of the present invention, a sliding part is provided on the shell, which is slidably connected to a sliding seat provided on the shell, and a limiting part for limiting the descending stroke of the shell is provided on the sliding seat. When cutting, the cutting machine is first started, the rotation speed is increased, and then it descends to contact the concrete surface. When cutting to a predetermined depth, the moving device moves along the guide rail to cut, wherein when cutting to a predetermined depth, it is limited by the limiting part, and the height of the limiting part can be adjusted.
[0009] As a further optimization scheme of the present invention, the limiting part is a threaded rod threadably connected to the sliding seat, and the height of the limiting part is adjusted by setting a threaded structure. A hexagonal cap can also be set on the top of the threaded rod to facilitate driving its rotation.
[0010] As a further optimization scheme of the present invention, a slow-descent device for slowly descending the slitting device is arranged in the shell, and the slow-descent device includes a piston cylinder arranged in the shell, a piston block arranged in the piston cylinder, a first pipe is arranged on the piston cylinder, and a flow control valve is arranged on the first pipe. An extension portion extending through the piston cylinder is arranged on the surface of the piston block, and a side arm is arranged on the outer shell. The side arm is used to contact with the extension portion and to support the outer shell to slowly descend. In this scheme, the slow-descent device is arranged so that the slitting device has a slow-descent function through the opening and closing of the flow control valve. When the flow control valve is closed, the extension portion supports the side arm to prevent the slitting device from descending. When the flow control valve is opened, the flow slowly flows out due to flow control, and the piston block slowly descends. This function is used to automatically and slowly descend the slitting device.
[0011] As a further optimization scheme of the present invention, the cooling component includes a water bucket, a second pipe connected to the water bucket, and a third pipe connected to the second pipe, the third pipe is connected to the cutting machine and is used to supply water to the slices of the cutting machine, wherein the first pipe, the second pipe and the third pipe are connected by a tee, and the tee is used to close the third pipe when the first pipe pumps water outwards, and the slices of the cutting machine need to be water-cooled when cutting. The tee is used to close the third pipe when the first pipe pumps water outwards, and when the water in the descending device is pressed out, the tee closes the third pipe to make the water flow against the drop to the second pipe, so that the air in the second pipe is discharged, so as to continuously supply water from the water bucket to the third pipe for cooling through the siphon phenomenon. This scheme places the water bucket at a high place on the slope, and the water automatically flows to the third pipe through the siphon phenomenon. However, when supplying water by pipe siphoning, it is necessary to fill the pipe with water first. In this regard, when the water supply device is put into use for the first time, water is pumped out through the descending device to fill the pipe with water.
[0012] As a further optimization scheme of the present invention, the three-way piece includes a valve body and a fan-shaped valve block rotatably arranged in the valve body, wherein the two straight surfaces of the fan-shaped valve block are used to correspond to the first pipeline and the third pipeline, wherein the shaft of the fan-shaped valve block makes the fan-shaped valve block and the first pipeline normally closed through an elastic torsion spring. This scheme specifically proposes a specific structure of the three-way piece. When the descending device is pressed down by the side arm and pumps water outward, the fan-shaped valve block is pushed to close the third pipeline, so that this part of the water fills the second pipeline, preventing the pumped water from being discharged directly through the third pipeline.
[0013] As a further optimization scheme of the present invention, a protrusion is provided at the connection point between the first pipeline and the valve body so that a gap is left between the fan-shaped valve block and the first pipeline. An elastic part is also provided in the piston cylinder, which is used to reset the piston block upward. The elastic part is provided to automatically reset the piston block to facilitate the next slow descent, wherein the elastic part can be a spring.
[0014] As a further optimization scheme of the present invention, a first roller is arranged on the guide rail, and a bracket is arranged on the surface of the guide rail, and a second roller is arranged at the bottom of the bracket. This scheme is used for transverse cutting of the slope, extending to the straight ground support guide rail through the bracket, and moving forward directly through the roller.
[0015] The beneficial effects of the present invention are:
[0016] The present invention sets a chain track as a moving device of the cutting device. Compared with a self-propelled cutting device, the track is not easy to move after being fixed, which helps to make the cutting straight and uniform. In addition, the chain and guide rail material structure is simple and common, and the chain track can be quickly built. It can be used not only for horizontal cutting of the slope, but also for longitudinal cutting. It will not deviate during cutting, which greatly improves the quality of cutting the slope concrete.

DETAILED DESCRIPTION
[0024] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.
[0025] Example 1
[0026] like Figure 1-5 As shown, a chain track concrete slope automatic seam cutting machine includes a guide rail 1, a moving device 2 movably arranged on the guide rail 1, a seam cutting device 3 arranged on the moving device 2, and a cooling assembly 5 for supplying water to the seam cutting device 3. A chain 12 is arranged on the guide rail 1, wherein the moving device 2 includes a shell 21, a driving part 22 arranged in the shell 21, and the shaft of the driving part 22 is provided with a sprocket 24 meshing with the chain 12. The seam cutting device 3 includes a shell 31 and a cutting machine 33, and the shell 31 is lifted and lowered on the shell 21.
[0027] A rail groove 11 is provided on the inner side of the guide rail 1, wherein an L-shaped arm is provided below the shell 21, and a guide wheel 23 rollingly connected to the rail groove 11 is provided at the end of the L-shaped arm, and the guide wheel 23 has at least two groups. In this scheme, the rail groove 11 is provided on the inner side of the guide rail 1, and at least two groups of guide wheels 23, i.e., four guide wheels 23, are used to limit the moving direction of the mobile device 2 and reduce friction.
[0028] A sliding portion 32 is provided on the shell 31, which is slidably connected to the sliding seat 25 provided on the shell 21, and a limiting portion 26 for limiting the descending stroke of the shell 31 is provided on the sliding seat 25. When cutting, the cutting machine 33 is first started, the rotation speed is increased, and then it is lowered to contact the concrete surface. When cutting to a predetermined depth, the mobile device 2 starts to move along the guide rail 1 to perform continuous cutting. When cutting to a predetermined depth, it is limited by the limiting portion 26. The height of the limiting portion 26 can be adjusted. The limiting portion 26 is a threaded rod threadedly connected to the sliding seat 25. The height of the limiting portion 26 is adjusted by setting a threaded structure. A hexagonal cap can also be provided on the top of the threaded rod to facilitate driving its rotation.
[0029] A slow-descent device 4 for slowly descending the slitting device 3 is arranged in the shell 21, and the slow-descent device 4 includes a piston cylinder 41 arranged in the shell 21, and a piston block 42 arranged in the piston cylinder 41. A first pipe 45 is arranged on the piston cylinder 41, and a flow control valve 46 is arranged on the first pipe 45. An extension portion 44 extending through the piston cylinder 41 is arranged on the surface of the piston block 42. A side arm 34 is arranged on the outer shell 31, and the side arm 34 is used to contact with the extension portion 44 to support the shell 31 to slowly descend. In this scheme, the slow-descent device 4 is arranged so that the slitting device 3 has a slow-descent function through the opening and closing of the flow control valve 46. When the flow control valve 46 is closed, the extension portion 44 supports the side arm 34 to prevent the slitting device 3 from descending. When the flow control valve 46 is opened, the flow slowly flows out due to flow control, and the piston block 42 slowly descends. This function is used to automatically and slowly descend the slitting device 3.
[0030] The cooling assembly 5 includes a water bucket 51, a second pipe 52 connected to the water bucket 51, and a third pipe 53 connected to the second pipe 52. The third pipe 53 is connected to the cutter 33 and is used to supply water to the slices of the cutter 33. The first pipe 45, the second pipe 52 and the third pipe 53 are connected through a tee. The tee is used to close the third pipe 53 when the first pipe 45 pumps water outward. The slices of the cutter 33 need to be water-cooled during slitting. The tee is used to close the third pipe 53 when the first pipe 45 pumps water outward. When the water in the device 5 is pressed out, the three-way piece closes the third pipe 53 to allow the water to flow against the drop in height to the second pipe 52, so that the air in the second pipe 52 is discharged, so that water can be continuously supplied from the water bucket 51 to the third pipe 53 for cooling through the siphon phenomenon. In this solution, by placing the water bucket 51 at a high point on the slope, the water automatically flows to the third pipe 53 through the siphon phenomenon. However, when supplying water by pipe siphon, it is necessary to fill the pipe with water first. In this regard, when the water supply device is put into use for the first time, water is pumped out through the descending device 4 to fill the pipe with water, without the need for manual water diversion.
[0031] The three-way piece includes a valve body 54 and a fan-shaped valve block 55 rotatably arranged in the valve body 54. The two flat surfaces of the fan-shaped valve block 55 are used to correspond to the first pipeline 45 and the third pipeline 53. The shaft of the fan-shaped valve block 55 is connected to the first pipeline 45 through an elastic torsion spring so that the fan-shaped valve block 55 and the first pipeline 45 are normally closed. This scheme specifically proposes a specific structure of the three-way piece. When the descent control device 4 is pressed down by the side arm 34 and pumps water outward, the fan-shaped valve block 55 is pushed to close the third pipeline 53, so that this part of the water fills the second pipeline 52, preventing the pumped water from being directly discharged through the third pipeline 53.
[0032] A protrusion 56 is provided at the connection point between the first pipeline 45 and the valve body 54 so that a gap is left between the fan-shaped valve block 55 and the first pipeline 45. An elastic part 43 is also provided in the piston cylinder 41, which is used to reset the piston block 42 upward. The elastic part 43 is provided to automatically reset the piston block 42 to facilitate the next slow descent, wherein the elastic part 43 can use a spring.
[0033] The specific implementation method is as follows: the guide rail 1 is placed into the slope by manual movement, the slitting device 3 is raised to the highest point by manual movement, and the flow control 46 is closed. In the process of transportation and movement, three people are generally required to carry out the transportation. The slitting device 3 can be directly lifted during the transportation process, and the limiter 26 is adjusted to limit the cutting depth. When cutting, the cutter 33 is turned on, and then the flow control valve 46 is turned on. The piston block 42 is pressed down by the side arm 34 to pump out water. In this process, the cutter 33 vertically cuts into the concrete from above and reaches a predetermined depth. degree, and the pumped water causes the fan-shaped valve block 55 to close the third pipe 53, and enters the second pipe 52 upward, discharges the gas in the second pipe 52, and fills the interior with water. When the piston block 42 no longer descends, the fan-shaped valve block 55 opens the third pipe 53, and the water in the second pipe 52 is continuously pumped into the third pipe 53 for cooling due to the siphon phenomenon. After cutting, the guide rail 1 is manually moved to the next slitting position, and the slitting device 3 is also lifted. The piston block 42 is reset under the push of the elastic part 43 to absorb the water back. When absorbing water, as shown in Figure 4 As shown, a protrusion 56 is provided to prevent the fan-shaped valve block 55 from being completely closed and to prevent air from being sucked in from the third pipe 53 . A one-way valve may be provided on the third pipe 53 .
[0034] After the handling is completed, the next cycle of slitting begins.
[0035] Example 2
[0036] like Figure 6As shown, on the basis of Example 1, this embodiment further provides a first roller 13 on the guide rail 1, and a bracket 14 is provided on the surface of the guide rail 1, and a second roller 15 is provided at the bottom of the bracket 14. This scheme is used for transverse slitting of the slope, and the guide rail 1 is supported by the bracket 14 and extends to the horizontal ground, and moves forward directly through the rollers. When in use, the guide rail 1 is kept fixed and then cut. After cutting, the moving device 3 returns to its original position, and the guide rail 1 and the bucket 51 are moved before the next cycle of slitting is carried out.
[0037] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
