Description

Technical Field

[0001] The invention belongs to the technical field of construction engineering machinery and equipment, and relates to a walking soil slope cutting device. Background Art

[0002] Existing soil slope cutting equipment is mainly divided into two categories. One type uses an excavator to perform preliminary excavation and slope cutting at a certain location. After the preliminary slope surface is dug out, it moves to the next location and performs preliminary excavation and slope cutting in the same way. Then, other equipment is used to complete the leveling and slope repair. The disadvantage is that the soil slope cutting is divided into two processes: preliminary excavation and slope cutting, and leveling and slope repair by other equipment, which has low work efficiency. The other type is track truss slope cutting equipment. Its principle is to preset walking tracks at the top and bottom of the slope, set up trusses on the tracks, and set up slope cutting and excavation devices on the trusses. After the trusses complete the slope cutting at one location, they move parallel to the next location to continue cutting the slope. This type of equipment can complete slope cutting and slope repair at the same location, but the movement of the truss is discontinuous, and this type of equipment is generally suitable for slope cutting construction on large slopes.

[0003] The common disadvantage of these two types of equipment is that they cannot combine soil cutting, slope repair, excavation, and device operation, making them difficult to apply to small and micro slope cutting in shallow trenches. Therefore, there is an urgent need to develop a new slope cutting device suitable for small and micro slope cutting, which can achieve the goals of simple process, strong flexibility, and high work efficiency.

The lower end of the oblique support 10 is fixedly connected to the hinge point of the main frame 7, and the high end of the oblique support 10 is hinged to the holding ring of the column 9. The oblique support 10 serves as an oblique support reinforcement component for the column 9 and the lifting adjustment rod 11 to achieve structural stability of the connection between the column and the main frame.

[0032] Reference Figure 2 、 Figure 3 The driving wheel has an overall truncated cone shape. The main body of the driving wheel is called the truncated cone shaft 22. A thin shaft 21 is fixed to each end of the truncated cone shaft 22 (supported by a pair of bearing supports on either side of the main frame 7). Three rings of chain plate drive teeth are arranged at intervals on the conical surface of the truncated cone shaft 22: a ring of chain plate drive teeth 1 23 near the large end, a ring of chain plate drive teeth 24 located in the middle of the shaft, and a ring of chain plate drive teeth 3 25 near the small end.

[0034] In addition, at least three cutting tools 30 are fixed radially on each sector-shaped cutting chain strip 26, and the V-shaped tips of all cutting tools 30 are facing the movement direction of the cutting chain strip 6; adjacent cutting tools 30 are spaced apart from each other in the circumferential direction and radial direction (that is, the distribution of the cutting tools 30 adopts a plum blossom arrangement, see Figure 4 Each sector-shaped cutting chain 26 is provided with a cutting surface trimming tool 31 at its radially outer edge. This tool is a straight-line tool, equivalent to a straight plate, located at the larger diameter end of the sector-shaped chain. When the device of the present invention moves forward as a whole, the cutting surface trimming tool 31 rotates with the cutting chain 6 and trims the cutting surface forward, smoothing the slope. The cutting tool 30 and the cutting surface trimming tool 31 are collectively referred to as the cutting tool 20. The tool 20 is used to cut soil and trim the cutting surface.

[0035] Reference Figure 5 The structure of the fixed frame 40 is that the fixed frame 40 is fixedly installed at the front end of the walking machine. The fixed frame 40 is a rectangular box as a whole. The side of the rectangular box fixedly connected to the walking machine is called the rear facade 42, and the side of the rectangular box connected to the main frame 7 is called the front facade 41. The front facade 41 must ensure that it is always located in the vertical plane during operation; three connection points for connecting with the main frame 7 are set in the front facade 41, namely the power output shaft hole 43 of the transmission mechanism, the arc-shaped waist hole 45 and the connecting plate 44, and a hinge connection 46 is fixedly set on the connecting plate 44; the transmission mechanism The dynamic mechanism serves as a power output device for distributing the power of the walking machine to the slope cutting device. The transmission mechanism is driven and connected to the driving shaft 1 of the driving wheel through the power output shaft hole 43 to provide rotational power for the driving wheel; the arc-shaped waist hole 45 is fixedly docked with the support rod in the support connection assembly 19, and the arc-shaped waist hole 45 realizes the main support and propulsion of the slope cutting device by supporting and locking the support connection assembly 19; the hinge connection 46 is connected to the lower end of the angle adjustment rod 12, and the hinge connection 46 cooperates with the angle adjustment rod 12 of the slope cutting device to adjust the section angle α of the soil slope.

[0036] Reference Figure 6 The structure of the angle adjustment connection assembly 18 is as follows: an adjustment seat 181 is fixed on the side of the main frame 7 facing the fixed frame 40; a rotating block 184 is hinged on the outer end surface of the adjustment seat 181 (the rotating block 184 is mounted on the adjustment seat 181 by a spherical hinge); a collar 182 is fixed on the outer end of the rotating block 184; the angle adjustment rod 12 is sleeved in the collar 182; a fastening component (such as a pin, a screw, etc.) with a function of locking and unlocking the angle adjustment rod 12 is provided on the collar 182. ), so that the collar 182 can slide or be fixedly locked with the angle adjustment rod 12. When the angle adjustment rod 12 is adjusted in length, the collar 182 rotates synchronously around the adjustment seat 181, and at the same time, the main frame 7 rotates around the driving shaft 1 to adjust the section angle α of the soil. A short column 183 facing the fixed frame 40 is fixed on the outer circular surface of the collar 182. The short column 183 is in contact with the front facade 41 of the fixed frame 40 to transmit the forward thrust of the walking machine to the slope cutting device.

[0037] The working principle of the device of the present invention is:

[0038] 1) The main frame 7 serves as the main component, and the auxiliary frame 8 serves as the telescopic portion. The telescopic sliding portion of the auxiliary frame 8 is inserted into the telescopic opening of the main frame 7 (for example, the two use inner and outer sleeves and limit pins to achieve telescopic adjustment and fixation). Similarly, the telescopic adjustment rod 17 adopts a telescopic adjustment sleeve structure, one end of which is fixed to the cross arm 15 and the other end is fixed to the cross arm 2 16. The expansion length of the main frame 7 and the auxiliary frame 8 is adjusted by the expansion and contraction of the telescopic adjustment rod 17, so that the expansion length of the entire frame is adapted to the length of the slope to be cut.

[0039] 2) Lift adjustment rod 11 is mounted within column 9, which serves as a telescopic outer tube. The upper end of rod 11 is fixedly connected to the thin shaft bearing seats at both ends of the adjusting wheel 5. Lift adjustment rod 11 slides up and down within the interior of column 9 to adjust the height of adjusting wheel 5. Inclined supports 10 ensure the structural stability of the connection between column 9, lift adjustment rod 11, and main frame 7.

[0040] 3) The lower guide plate 13 is a lower guide plate for cutting and projecting soil materials, and is fixed to the distal end of the auxiliary frame 8. The upper guide plate 14 is an upper guide plate for cutting and projecting soil materials, and is fixed to the distal end of the auxiliary frame 8.

[0041] 4) The driving wheel is supported on the main frame 7 by bearings through thin shafts 21 at both ends, and its large end is connected to the rotary power drive through the driving shaft 1. The intermediate wheel 3 is in the shape of a truncated cone, and is also supported by thin shaft bearings at both ends near the lower end of the auxiliary frame 8, and is a driven wheel. The distal wheel 4 is in the shape of a truncated cone, and is supported by bearings at the top of the auxiliary frame 8 near the top of the slope through thin shafts at both ends, and is a driven wheel. The adjusting wheel 5 is in the shape of a truncated cone, and is supported by bearings at the top of the lifting adjustment rod 11 through thin shafts at both ends, and is a driven wheel. The cutting chain plate 6 plays the role of a transmission chain, and is wrapped around the above-mentioned driving wheel and three driven wheels.

[0042] 5) When the angle adjustment lever 12 is actuated, the main frame 7 and auxiliary frame 8 rotate together about the drive shaft 1. The supporting connection assembly 19 fixed to the upright column 9 inevitably undergoes an arcuate motion within the vertical plane. Its connection to the fixed frame 40 at the front end of the walking machine must also be able to accommodate this arcuate motion. Therefore, a corresponding arcuate waist hole 45 is provided on the fixed frame 40. This allows the supporting connection assembly 19 on the slope-cutting device to be inserted into the arcuate waist hole 45 during connection. This arcuate waist hole 45 allows the supporting connection assembly 19 to be released when adjusting the cutting angle α of the soil slope surface, allowing the supporting connection assembly 19 to move freely within the arcuate waist hole 45. Once the adjusted angle is determined, the supporting connection assembly 19 is securely locked in the arcuate waist hole 45.

[0043] The structural innovation of the device of the present invention is:

[0044] First, the main frame 7 and auxiliary frame 8 form a coordinated, adjustable, telescopic truss to accommodate overall length adjustments within a specified slope range. The height of the adjusting wheel 5 is also adjustable. The telescopic adjustment rod 17, the lifting adjustment rod 11, and the supporting connection assembly 19 feature a linkage mechanism for synchronized adjustment (manual or hydraulic), ensuring the tension of the cutting chain 6 at all times. Furthermore, the angle adjustment rod 12 and its angle adjustment connection assembly 18 allow the frame to be adjusted with respect to the horizontal plane, ensuring that the slope formed by the cut surface is aligned with the designed cutting angle α.

[0045] Second, a number of V-shaped cutting tools 30 are fixed on the cutting chain plate 6, which have the function of cutting soil and transporting soil materials. They are distributed in a plum blossom shape. A straight-line cutting surface trimming tool 31 is installed on the edge of the large head end of the cutting chain plate 6 to ensure that an oblique cutting surface is formed when the frame moves axially toward the front driving wheel, and the cutting surface is trimmed while moving forward and cutting.

[0046] Third, the device of the present invention is connected to the walking machine through the fixed frame 40, and the arc-shaped waist hole 45 on the fixed frame 40 is connected to the support connection assembly 19 on the slope cutting device, providing the thrust for the slope cutting device to move forward, thereby realizing the synchronous movement of the slope cutting device and the walking machine; the hinge connection 46 on the fixed frame 40 is connected to the angle adjustment rod 12 on the slope cutting device to realize the adjustment of the soil section angle α and provide the thrust for the slope cutting device to move forward; the transmission mechanism on the fixed frame 40 is connected to the driving shaft 1 on the slope cutting device, thereby realizing the transmission of the rotational power of the walking machine to the slope cutting device and providing the thrust for forward movement.

[0047] The working process of the device of the present invention is:

[0048] The fixed frame 40 is fixed to the front end of the walking machine and is connected and fixed to the device of the present invention through three connection points. When the walking machine moves forward in the vertical direction of the slope (refer to Figure 1 The slope cutting device also moves forward.

[0049] First, the unfolded lengths of the main frame 7 and the auxiliary frame 8 are adjusted according to the length of the slope to be trimmed.

[0050] See Figure 1 Place the lowest surface (large end) of the driving wheel at the bottom of the slope. Based on the desired length of the slope, adjust the lifting and lowering levers 11 and telescopic levers 17 in a coordinated manner until the distal end of the sub-frame 8 reaches the top of the slope. Specifically, when the sub-frame 8 needs to be extended toward the top of the slope, the lifting and lowering levers 11 are shortened (lowering the height of the adjusting wheel 5) while the telescopic levers 17 are extended. This allows the cutting chain 6 to fully extend under the combined constraints of the driving wheel and each driven wheel, achieving the desired tension. When the extended length of the sub-frame 8 needs to be retracted, the telescopic levers 17 are shortened while the lifting and lowering levers 11 are extended (raising the height of the adjusting wheel 5). This allows the cutting chain 6 to fully extend under the combined constraints of the driving wheel and each driven wheel, achieving the desired tension.

[0051] Secondly, according to the slope of the slope to be arranged, the angle between the main frame 7, the auxiliary frame 8 and the horizontal plane is adjusted to reach the required angle α.

[0052] During the upward and downward adjustment of the angle adjustment rod 12, its lower end is hinged to the hinge connection 46 (not released during adjustment). The collar 182 (along with the rotating block 184) in the angle adjustment connection assembly 18 rotates around the adjustment seat 181. The main frame 7 and sub-frame 8 can only rotate (forward or reverse) around the drive shaft 1. As the angle adjustment rod 12 lengthens or shortens between the hinge connection 46 and the adjustment seat 181, the axial direction must be able to adaptively rotate. Therefore, the collar 182 must be able to rotate around its adjustment seat 181; otherwise, it will easily become stuck and damage the components. The main frame 7 and sub-frame 8 rotate integrally around the drive shaft 1. Furthermore, when the walking machine moves forward, the short column 183 transmits the forward thrust of the walking machine to the main frame 7 via the collar 182, rotating block 184, and adjustment seat 181, providing thrust for the slope-cutting machine's forward movement. Since the angle adjustment rod 12 passes through the collar 182 to adjust the rod length from the hinge connection 46 to the adjustment seat 181, thereby adjusting the soil section angle α, the collar 182 must also have the function of loosening and fixing the angle adjustment rod 12. When the soil section angle α is to be adjusted, the fastening assembly provided on the collar 182 is loosened, and the collar 182 can loosen the angle adjustment rod 12 so that it can slide up and down to adjust the rod length between the hinge connection 46 and the adjustment seat 181; when adjusted to the required angle, the fastening assembly is tightened, and the collar 182 can lock and fix the angle adjustment rod 12, ensuring that the section angle α always remains unchanged during the cutting operation.

[0053] Again, after the section angle α is adjusted, the angle adjustment rod 12 is firmly fixed with the tightening assembly and the collar 182, the support rod of the supporting connection assembly 19 is inserted into the arc-shaped waist hole 45 of the fixed frame 40 for secure connection, the rotational power is connected to the driving shaft 1 through the power output shaft hole 43 of the transmission mechanism, and the short column 183 is made to press against the front facade 41.

[0054] Finally, the forward driving force and the rotational force on the walking machine are activated. The walking machine relies on the forward driving force to propel the device of the present invention forward. At the same time, under the action of the rotational force, the driving shaft 1 drives the driving wheel to rotate, and the three rows of chain plate transmission teeth on the conical surface of the driving wheel drive the cutting chain plate 6 to move counterclockwise (see Figure 1 Under the constraints of the drive wheels, the cutting tool 30 of the cutting chain 6, placed close to the ground, exerts force forward and upward, cutting the soil to form a cut surface. The soil is then ejected at the top of the slope, where it is guided to the top by the lower guide plate 13 and the upper guide plate 14 (the soil ejection guide plate). Simultaneously, the cut surface is smoothed by the cut surface finishing tool 31. Because each drive wheel is a truncated cone axis, with its axis perpendicular to the length of the frame (i.e., the forward direction of the traveling machine), the inventive device can cut the soil horizontally while moving forward, forming the desired extended cut surface, by controlling the forward speed of the traveling machine.

[0055] Example 1

[0056] For a certain slope, construction is carried out at a cutting angle of 30 degrees.

[0057] Reference Figure 1 First, adjust the structure of the device according to the present invention. By adjusting the telescopic adjustment rod 17, the overall length of the main frame 7 and auxiliary frame 8 is adjusted to 0.8 meters (the wheel diameter can be reduced to accommodate short slope excavation and slope correction). Simultaneously, by adjusting the height of the lifting adjustment rod 11 installed in the column 9, the two thin shafts of the adjusting wheel 5 can move up and down along the long groove of the column 9 to achieve height adjustment of the adjusting wheel 5, jointly deploying the cutting chain 6 and maintaining appropriate transmission tension. Connect the hinge 46 on the fixed frame 40 to the angle adjustment rod 12 on the slope cutting device. Adjust the angle adjustment rod 12 to adjust the soil section angle α to 30 degrees. Then, connect the curved waist hole 45 on the fixed frame 40 to the support connection assembly 19 on the slope cutting device. Connect the transmission mechanism on the frame 40 to the driving shaft 1 of the slope cutting device. Ensure that the short column 183 is pressed against the front facade 41, control the travel speed of the walking machine, and then begin construction operations.

[0058] Example 2

[0059] For a certain slope, construction is carried out at a cutting angle of 20 degrees.
