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 is to use an excavator to perform preliminary soil excavation and slope cutting at a certain location. After the preliminary slope surface is dug out, it moves to the next location to perform preliminary soil excavation and slope cutting in the same way, and then uses other equipment to complete the leveling and slope repair. Its disadvantage is that the soil slope cutting is divided into two processes: preliminary soil excavation and slope cutting and other equipment leveling and slope repair, and the work efficiency is low. The other is the track truss type 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 the slope cutting. This type of equipment can complete slope cutting and slope repair at one 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 the above two types of equipment is that they cannot combine soil slope cutting, slope repair, excavation, and device walking together, and are difficult to be applied to the slope cutting construction of small and micro slopes in shallow ditches. Therefore, it is urgent to develop a new slope cutting device that is suitable for the slope cutting of small and micro slopes, so as to achieve the purpose of simple process, strong flexibility, and high work efficiency.

The cutting tool 30 and the cutting surface trimming tool 31 are collectively referred to as the tool 20, and the tool 20 is used for cutting soil and trimming the cutting surface.

[0024] Reference Figure 5The 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 be ensured to always be located in a vertical plane during the working process; 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 waist hole 45 and the connecting plate 44, and a hinge connection 46 is fixedly set on the connecting plate 44; the transmission The mechanism serves as a power output device for distributing the power of the walking machine to the slope cutting device. The transmission mechanism is connected to the driving shaft 1 of the driving wheel 2 through the power output shaft hole 43 to provide the rotational power of the driving wheel 2; the arc-shaped waist hole 45 is fixedly docked with the support rod in the supporting 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 supporting 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.

[0025] Reference Figure 6 The structure of the angle adjustment connection assembly 18 is that an adjustment seat 181 is fixed on the main frame 7 on the side facing the fixed frame 40, and a rotating block 184 is hinged on the outer end surface of the adjustment seat 181 (the rotating block 184 is installed on the adjustment seat 181 by a spherical hinge); a collar 182 is fixed on the outer end of the rotating block 184, and the angle adjustment rod 12 is sleeved in the collar 182, and a fastening assembly (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 body; a short column 183 facing the fixed frame 40 is fixed on the outer circumferential surface of the collar 182, and 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.

[0026] The working principle of the device of the present invention is: 1) The main frame 7 is the main component, and the auxiliary frame 8 is the telescopic part. The telescopic sliding part of the auxiliary frame 8 is inserted into the telescopic opening of the main frame 7 (for example, the two adopt 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 in the cross arm 15, and the other end is fixed in 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 overall frame is adapted to the length of the slope to be cut.

[0027] 2) The lifting and adjusting rod 11 is sleeved in the column 9 as a telescopic outer cylinder, and the upper end of the lifting and adjusting rod 11 is fixedly connected to the thin shaft bearing seats at both ends of the adjusting wheel 5. The lifting and adjusting rod 11 slides up and down in the inner cavity of the column 9 to adjust the height of the adjusting wheel 5. The oblique support 10 ensures the structural stability of the connection between the column 9 and the lifting and adjusting rod 11 and the main frame 7.

[0028] 3) The lower guide plate 13 is a lower guide plate for cutting and projecting soil materials, and is fixed to the far 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 far end of the auxiliary frame 8.

[0029] 4) The driving wheel 2 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 near the lower end of the auxiliary frame 8 by bearings through thin shafts at both ends, and is a driven wheel. The distal wheel 4 is in the shape of a truncated cone, and is supported at the top of the auxiliary frame 8 near the top of the slope by bearings 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 at the top of the lifting and adjusting rod 11 by bearings 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 2 and three driven wheels.

[0030] 5) When the angle adjustment rod 12 is in motion, the main frame 7 and the auxiliary frame 8 rotate together around the driving shaft 1, and the supporting connection assembly 19 fixed on the column 9 must make an arc motion in the vertical plane, and its connection with the fixed frame 40 at the front end of the walking machine must also be able to adapt to this arc motion. Therefore, an arc-shaped waist hole 45 is correspondingly provided on the fixed frame 40, so that the supporting connection assembly 19 on the slope cutting device can be inserted into the arc-shaped waist hole 45 when connected, and can be loosened when adjusting the section angle α of the soil slope surface, allowing the supporting connection assembly 19 to move freely in the arc-shaped waist hole 45; when the adjustment angle is determined, the supporting connection assembly 19 is fixed and locked in the arc-shaped waist hole 45.

[0031] The structural innovation of the device of the present invention is: First, the main frame 7 and the auxiliary frame 8 are mutually coordinated adjustable telescopic trusses to meet the overall length adjustment requirements of the slope length within a certain range. The height of the adjusting wheel 5 can also be adjusted, and the telescopic adjustment rod 17, the lifting adjustment rod 11 and the supporting connection assembly 19 have a linkage mechanism to achieve synchronous adjustment (manual adjustment or hydraulic adjustment) to always ensure the tension state of the cutting chain plate 6. In addition, the angle α between the frame and the horizontal plane can be adjusted through the angle adjustment rod 12 and its angle adjustment connection assembly 18 to ensure that the angle between the slope formed by cutting the soil surface and the horizontal plane is the designed cutting angle α.

[0032] Second, a plurality 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, and 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 cutting movement is formed when the frame moves axially toward the front driving wheel, and the cutting surface is trimmed while moving forward and cutting.

[0033] 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 supporting connection assembly 19 on the slope-cutting device, providing a 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, thereby realizing the adjustment of the soil section angle α and providing a 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 a thrust for forward movement.

[0034] The working process of the device of the present invention is: 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 In the front and rear direction), the slope cutting device also moves forward.

[0035] 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 prepared.

[0036] See Figure 1 , place the lowest surface (big end) of the driving wheel 2 at the elevation of the bottom of the slope, and adjust the lifting and lowering adjustment rod 11 and the telescopic adjustment rod 17 in conjunction with each other according to the slope length of the soil body to be cut, so that the far end of the auxiliary frame 8 reaches the top of the slope. That is, when the auxiliary frame 8 needs to be extended toward the top of the slope, the lifting and lowering adjustment rod 11 is shortened (lowering the height of the adjusting wheel 5), and the telescopic adjustment rod 17 is extended, and the cutting chain plate 6 is fully extended under the joint constraint of the driving wheel and each driven wheel, and the tension is appropriate. When the extended length of the auxiliary frame 8 needs to be retracted, the telescopic adjustment rod 17 is shortened, and the lifting and lowering adjustment rod 11 is extended (raising the height of the adjusting wheel 5), and the cutting chain plate 6 is fully extended under the joint constraint of the driving wheel and each driven wheel, and the tension is appropriate.

[0037] Secondly, according to the slope of the slope to be prepared, the angles between the main frame 7, the auxiliary frame 8 and the horizontal plane are adjusted to reach the required angle α.

[0038] During the process of adjusting the angle adjustment rod 12 up and down, the lower end of the angle adjustment rod 12 is hinged to the hinge connection 46 (not released during the adjustment process), and the collar 182 (together with the rotating block 184) in the angle adjustment connection assembly 18 rotates around the adjustment seat 181. The main frame 7 and the auxiliary frame 8 can only rotate around the driving shaft 1 (forward or reverse) together. When the angle adjustment rod 12 becomes longer or shorter from the hinge connection 46 to the adjustment seat 181, the axial direction of the angle adjustment rod 12 must be able to make adaptive rotation, so the collar 182 must be able to rotate around its adjustment seat 181, otherwise it is easy to get stuck and damage the parts. The main frame 7 and the auxiliary frame 8 rotate around the driving shaft 1 as a whole. In addition, when the walking machine moves forward, the short column 183 transmits the thrust of the walking machine's forward movement to the main frame 7 through the collar 182, the rotating block 184, and the adjustment seat 181 in turn, providing thrust for the slope cutting machine to move forward. Since the angle adjustment rod 12 passes through the ring 182 to adjust the rod length from the hinge connection 46 to the adjustment seat 181 to achieve the adjustment of the soil section angle α, the ring 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 fixing component provided on the ring 182 is loosened, and the ring 182 can loosen the angle adjustment rod 12 so that it can slide up and down to adjust the rod length from the hinge connection 46 to the adjustment seat 181; when the required angle is adjusted, the fixing component is tightened, and the ring 182 can lock and fix the angle adjustment rod 12 to ensure that the section angle α is always kept unchanged during the cutting operation.

[0039] Again, after the section angle α is adjusted, the angle adjustment rod 12 is firmly fixed with the fixing assembly and the collar 182, the supporting rod of the supporting connection assembly 19 is inserted into the arc-shaped waist hole 45 of the fixed frame 40 for reliable fixation, the driving shaft 1 is connected to the rotational power 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.

[0040] Finally, the forward driving force and the rotational force on the walking machine are started. The walking machine relies on the forward driving force to push 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 2 to rotate, and the three rows of chain plate transmission teeth on the cone surface of the driving wheel 2 drive the cutting chain plate 6 to move counterclockwise (see Figure 1 ); Under the constraint of each transmission wheel, the cutting tool 30 of the cutting chain plate 6 close to the ground exerts force forward and upward to cut the soil to form a section, and throws the soil at the top of the slope, and the lower guide plate 13 and the upper guide plate 14 (soil ejection guide plate) guide the cut soil to the top of the slope; at the same time, under the action of the section finishing tool 31, the section is made flat. Since each transmission wheel is a truncated cone axis, its axial direction is located in the vertical direction of the frame length (that is, the forward direction of the walking machine), when the walking machine moves forward, the appropriate forward speed is controlled, and the invention device can cut the soil horizontally while moving forward to form the required extended section.

[0041] Example 1 For a certain slope, construction is carried out at a cutting angle of 30 degrees.

[0042] Reference Figure 1 , firstly, adjust according to the above structure of the device of the present invention, by adjusting the telescopic adjustment rod 17, the overall length of the main frame 7 and the auxiliary frame 8 is adjusted to 0.8 meters (the wheel diameter can be made smaller to adapt to the excavation and slope correction of short slopes), and at the same time, by adjusting the height of the lifting adjustment rod 11 set in the column 9, the thin shafts at both ends of the adjustment wheel 5 can move up and down along the long groove of the column 9 to achieve the height adjustment of the adjustment wheel 5, and jointly unfold the cutting chain plate 6 to maintain the appropriate transmission tension; connect the hinge connection 46 on the fixed frame 40 with the angle adjustment rod 12 on the slope cutting device, adjust the angle adjustment rod 12, and adjust the soil section angle α to 30 degrees. Then, connect the arc waist hole 45 on the fixed frame 40 with the support connection assembly 19 on the slope cutting device; the transmission mechanism on the frame 40 is connected to the driving shaft 1 on the slope cutting device, and determine that the short column 183 is pressed against the front facade 41, and the appropriate travel speed of the walking machine is controlled, and the construction operation can be started.
