Description

Technical Field

[0001] The invention belongs to the technical field of slope soil compaction, and relates to a walking type soil slope compaction machine. Background Art

[0002] Foundation finishing is to modify the bearing capacity of the foundation. Usually, compacting equipment is needed to knock and compact the surface of the foundation to make the soft foundation more solid and firm, making it suitable for construction. There are still some problems when using the existing compacting machines for foundation correction.

[0003] In civil engineering projects, soil slope compaction problems often occur, such as the slope compaction problem of trapezoidal channels and the slope compaction problem of bridge abutments facing the river. The solution to these problems depends on efficient mechanical construction, so it is necessary to develop efficient slope soil compaction machinery.

[0004] The existing slope soil tamping construction includes manually operated machines and mechanically driven machines, most of which are flat-plate machines. Most of the flat-plate machines have a small working area and low tamping efficiency. Due to the tamping construction on the slope, it is difficult to control the walking and operation, especially manual operation, and the tamping uniformity and tamping quality are not easy to guarantee. Summary of the invention

The connecting plate 282 is fixed to the main rammed earth plate through a threaded hole 1 283, and the outer end of the connecting plate 282 is fixedly connected to the laminated plate 281 through a threaded hole 284. The number of laminated plates 281 is increased or decreased as needed to achieve the overall length expansion and contraction of the combined rammed earth plate 28.

[0021] Reference Fig.11A group of movable ramming plates is also arranged at the position of each pair of columns 8, and each group of movable ramming plates includes an alternating ramming plate 1 9 and an alternating ramming plate 2 10, wherein the alternating ramming plate 1 9 and the alternating ramming plate 2 10 have the same structure, the bottom of the alternating ramming plate 1 9 is a ramming plate, and the two sides of the ramming plate are connected upward with side columns 35, which are called a pair of side columns 35, and the side columns 35 are slidably connected to the columns 8 in the form of a slide groove; a set of lever assemblies is arranged on the upper part of each side column 35, and the upper end surface of each side column 35 is a plane, which is used for embedding and top connection with the pad swing arm 40 during the ramming process; Reference Fig.13 The structure of the lever assembly on the side column 35 is that it includes a lever hinge 364 fixed on the side column 35, and a lever 361 is hinged on the lever hinge 364.

[0022] See Fig.13 , Fig.14 The pad block swing arm 40 is a key component for alternate tamping. Under the action of the inertial flywheel 27, the entire frame is lifted off and tamped downward. During this process, the two side swing arms of the pad block swing arm 40 swing back and forth, so that the upper end surfaces of the side columns 35 of the alternate tamping plate 1 9 and the alternate tamping plate 2 10 are alternately padded and the soil is alternately tamped. A pair of striker assemblies 49 are symmetrically installed on each pad swing arm 40. The structure of each striker assembly 49 is that it includes a striker body 491.

The support spring 492 is in contact with the baffle 494 upwards, and the support spring 492 is in contact with the ring 495 downwards, so as to ensure that the striker body 491 can move up and down in the upper ring 493 and the lower ring 495. When the striker body 491 moves downward, the support spring 492 is compressed to store energy, and then the support spring 492 releases energy and stretches, so that the striker body 491 is reset upwards.

[0023] Reference Fig.12 , Fig.14 , Fig.15 , Fig.16A set of alternating tamping mechanisms is installed on the inner side of each column 8. The alternating tamping mechanisms on both sides of the longitudinal direction are arranged in pairs. The structure of each set of alternating tamping mechanisms is that the upper surface of the upper longitudinal beam 6 is called the top surface 37, and the vertical surface of the upper longitudinal beam 6 is called the facade 44 (see Fig. 9 ), the inner surface of the vertical surface 44 is fixedly connected to the column 8, a vertical swing arm shaft 39 is fixed to the inner surface of each column 8, a cushion swing arm 40 is hinged on the swing arm shaft 39, a pair of torsion springs 41 are also mounted on the swing arm shaft 39, the two ends of the cushion swing arm 40 are respectively connected to the free end of a torsion spring 41, and the fixed ends of the two torsion springs 41 are fixedly connected to the swing arm shaft 39 (or to the column 8 next to it) (see Fig.12 ); Blind holes are respectively opened on both end surfaces of the cushion block swing arm 40, and a telescopic push rod 42 is installed in each blind hole; A synchronous adjustment rod 23 is arranged above each top surface 37 along the longitudinal direction of the upper longitudinal beam 6. The two synchronous adjustment rods 23 are connected to the top surface 37 of the upper longitudinal beam 6 through a connecting component to achieve support on the top surface 37; each pad swing arm 40 is only vertically fixedly connected to a vertical rod 38 at one end, and the upper end of the vertical rod 38 is hinged to the synchronous adjustment rod 23; each column 8 is connected to the side columns 35 on both sides (in the longitudinal beam direction) of the column 8 by a sliding groove, allowing the side columns 35 to slide up and down along the side of the column 8, thereby driving the movable rammed earth plate to move up and down.

[0024] See Fig.15 The synchronous adjustment rod 23 is fixedly connected to the top surface 37 of the upper longitudinal beam 6 by a rotatable connecting assembly. The connecting part of the synchronous adjustment rod 23 is called an adjustment assembly. The structure of the adjustment assembly is that it includes a connecting vertical rod 233. The lower end of the connecting vertical rod 233 is fixed to the top surface 37 of the upper longitudinal beam 6. The upper end of the connecting vertical rod 233 is hinged to the connecting cross rod 231 through a bearing 232. The connecting cross rod 231 is hinged to the synchronous adjustment rod 23.

[0025] See Fig.14 , Fig.15 , Fig.16A pair of obstacle assemblies 43 are symmetrically arranged on both sides of each column 8, and the pair of obstacle assemblies 43 are both located on the inner surface of the facade 44; the structure of each obstacle assembly 43 is: including a base 45 fixed on the inner surface of the facade 44, the base 45 is hinged to the obstacle plate 47 through a hinge seat 46, and an obstacle body 48 is fixedly arranged on the side of the obstacle plate 47 facing the telescopic top rod 42, and the surface of the obstacle body 48 facing the telescopic top rod 42 is set as an inclined surface or an inclined curved surface, the free end of the telescopic top rod 42 is spherical and can roll or slide, and the telescopic top rod 42 maintains smooth contact with the inclined surface or inclined curved surface of the obstacle body 48. In the obstacle assembly 43, the obstacle plate 47 is connected to the base 45 through a hinge seat 46, and the hinge seat 46 is a semi-plane hinge, which is limited to upward movement, and the movement angle is less than 90 degrees. The obstacle plate 47 can only rotate upward at a limited angle.

[0026] The working principle of the device of the present invention is described as follows: 1) The bottom of each stand on the slope (i.e., stand 1, stand 2, stand 3, and stand 4) is equipped with a fixed rammed earth plate 26 of the same structure; the bottom of stand 5 (i.e., the stand at the bottom of the slope) is a fixed and one-way laminated telescopic (towards the slope foot) combined rammed earth plate 28. Since the slope surface has a certain angle, and the combined rammed earth plate 28 is perpendicular to the slope surface, part of the soil at the slope foot will not be compacted. Therefore, the combined rammed earth plate 28 is set as a rammed earth plate with a telescopic structure, and the number of laminated plates 281 can be determined according to needs. In the process of tamping the slope surface, the slope foot can be fully compacted without leaving any gaps.

[0027] 2) The device of the present invention drives the driving gear 15 through the power device M, which is then divided into two transmission routes, and at the same time drives the transmission gear 14-transmission shaft 13-bevel gear 2 17-bevel gear 1 16-inertia flywheel shaft 21 on both sides to rotate, and the inertia flywheel 27 then rotates with the inertia flywheel shaft 21. When all the inertia flywheels 27 move to the high position, under the action of rotational inertia, the tamping frame is vacated, and the fixed tamping plate 26 and the combined tamping plate 28 are vacated together; when all the inertia flywheels 27 move downward to the bottom position, under the action of rotational inertia, the fixed tamping plate 26 and the combined tamping plate 28 hit the slope soil together to tamp the slope soil.

[0028] 3) Reference Figure 7 and Figure 8 The multiple frames on the slope have the same structure, but are arranged symmetrically in front and behind, for example. Figure 6In the top view, the bevel gear sets on the stand 1 and the stand 3 are arranged on the same side, and the bevel gear sets on the stand 2 and the stand 4 are located on the other side. Generally speaking, the stand 1 and the stand 2 are a group of adjacent combined structures, the purpose of which is to make the inertia flywheels 27 of the two driven by different transmission shafts 13 on both sides rotate in opposite directions, so that the inertia flywheels 27 of the two are opposite in direction of the slope surface (longitudinal beam length direction) and cancel each other out, that is, the tamping frame will not be displaced along the slope surface due to the same direction movement of the inertia flywheel 27; the tamping frame will only produce up and down movement perpendicular to the slope surface due to the movement of the inertia flywheel 27, that is, the tamping frame will be lifted up and hit the slope surface to tamp the soil. The stand 3 and the stand 4 are another group of adjacent combined structures, and their working principle is the same as that of the stand 1 and the stand 2. Therefore, when the slope is longer, the number of frames needs to be increased, and a combination structure of two frames is required to be added; when the slope is shorter, the number of frames needs to be reduced, and a combination structure of two frames is required to be reduced.

[0029] 4) A pair of synchronous adjustment rods 23 are provided along the longitudinal sides. The function is that, since the multiple pad swing arms 40 on each side are hinged to the synchronous adjustment rod 23 on the same side through their respective vertical rods 38, it is only necessary to pull or push the synchronous adjustment rods 23 on both sides before the tamping operation to unify the swinging states of all the pad swing arms 40 on both sides, so that all the alternating tamping plates (alternating tamping plate 1 9 or alternating tamping plate 2 10) can rise and fall together. The purpose is to uniformly position the pads at the upper end of the side columns of a certain movable tamping plate before starting the operation (that is, either position the pads at the upper end of the side columns 35 of each alternating tamping plate 1 9, or position the pads at the upper end of the side columns 35 of each alternating tamping plate 2 10), so as to ensure the normal alternating operation of the movable tamping plates after starting.

[0030] 5) The principle of a pair of torsion springs 41 on each pad swing arm 40 is: the torsion springs 41 are a pair of springs with opposite effects, one end of the two torsion springs 41 is fixedly connected to the column 8 (or swing arm shaft 39), and the other ends of the two torsion springs 41 are respectively connected to the left and right ends of the pad swing arm 40, so when the pad swing arm 40 turns to one side, one torsion spring 41 releases energy to promote rotation, while the other torsion spring 41 stores energy during rotation. When the telescopic top rod 42 on the side of one end of the pad swing arm 40 is out of the control of the obstacle 48, the torsion spring 41 that stores energy will release energy, causing the pad swing arm 40 to rotate to the other side.

[0031] 6) The principle of the lever assembly on the side column 35 is that the limiting column 363 is used to limit the force rod 362 from moving too much upward (because the length of the side rod of the action rod 36 is greater than the lever 361, the mass is relatively heavy, and the inertia of the downward rush is large, and the top of the force rod 362 is not allowed to exceed the top surface of the side column 35). When the top of the force rod 362 is subjected to force and moves downward, due to the lever action of the lever 361, the action rod 36 moves upward, lifts the obstacle plate 47, shifts the obstacle body 48, releases the telescopic push rod 42, and makes the cushion swing arm 40 rotate to the other side. Subsequently, the action rod 36 rotates clockwise around the lever hinge 364 under the action of gravity, and stops rotating due to the restriction of the limiting column 363.

[0032] When the pad block swing arm 40 is located at the upper part of the side column 35 and the tamping machine frame as a whole tamps the soil downward, the striker body 491 is affected by inertia and impacts downward, causing displacement, and the support spring 492 is compressed to store energy. At the same time, the striker body 491 strikes the force rod 362 in the lever assembly downward. Due to the action of the lever, the action rod 36 lifts the obstacle plate 47, thereby realizing the rotation of the pad block swing arm 40 in the other direction.

[0033] 7) The significance of alternating tamping is that due to alternating tamping, the area of ​​the soil being tamped becomes smaller, thereby increasing the pressure of the tamped soil, increasing the tamping depth of the soil, and improving the tamping efficiency.

[0034] The principle of alternating rammed earth for each set of alternating rammed earth panels is: Fig.12For example, before starting work, the pad block swing arms 40 on both sides are pulled respectively by the synchronous adjustment rods 23 on the same side. Since the side columns 35 can move up and down along the columns 8, the right ends of all the pad block swing arms 40 on both sides are synchronously rotated to the empty space on the upper end surface of the side columns 35 of the alternating rammed earth plate 2 10. The upper parts of the side columns 35 of all the alternating rammed earth plates 2 10 are in a low position because of the pad block swing arms 40. At this time, the left end of the pad block swing arm 40 is rotated to the outer side of the upper part of the side column 35 of the alternating rammed earth plate 1 9 of the same group. The upper parts of the side columns 35 of all the alternating rammed earth plates 1 9 are in a high position because they are not stuck in the pad block swing arms 40. When the work starts, the fixed ramming plate 26 and the alternating ramming plate 10 ram the soil on the slope under the action of the downward movement of the inertia flywheel 27. When the alternating ramming plate 10 hits the soil, the soil at the bottom is compacted. At the same time, the striker assembly 49 on the right side of the pad swing arm 40 strikes one end of the lever assembly on the upper part of the side column 35 under the inertia downward rush. The other end of the lever assembly pushes up the right obstacle plate 47, so that the telescopic push rod 42 on the right end of the pad swing arm 40 is separated from the control of the obstacle 48. Under the action of a pair of torsion springs 41, the pad swing arm 40 swings and rotates; at the same time, in the process of the inertia flywheel 27 rising upward, the entire tamping frame is vacated. At this time, the distance between the upper part of the side column 35 of all the alternating tamping plates 9 and the top surface 37 of the upper longitudinal beam 6 increases. Under the action of the torsion spring 41, the left end of the pad swing arm 40 enters the space between the upper part of the side column 35 of the alternating tamping plate 9 and the top surface 37, and the telescopic top rod 42 passes over the obstacle 48 on the left and is controlled by the obstacle 48. When the inertia flywheel 27 runs to the low position again, the whole tamping frame moves downward. Since the alternating tamping plate 2 10 is not supported by the pad swing arm 40, its side column 35 can slide upward along the column 8, so that the space between its upper part and the top surface 37 is reduced. The upper part of the side column 35 of the alternating tamping plate 1 9 is supported by the pad swing arm 40, so that the fixed tamping plate 26 and the alternating tamping plate 1 9 tamp the soil at the same time. At the same time, the striker assembly 49 on the pad swing arm 40 on all the alternating tamping plates 1 9 hits one end of the lever assembly on the upper part of the side column 35 under the action of the downward inertia impulse, and the other end of the lever assembly lifts the obstacle plate 47 above it, so that the telescopic push rod 42 at the left end is out of the control of the obstacle 48. When the inertia flywheel 27 rises upward, the pair of torsion springs 41 play a role again, and the pad swing arm 40 swings in the opposite direction again. This cycle is repeated one after another to achieve the control of alternating tamping.
