Description

Technical Field

[0001] This invention relates to the field of foundation engineering technology. More specifically, this invention relates to equipment for compacting foundations during airport construction. Background Technology

[0002] During airport ground construction, the foundation needs to be compacted. In actual use, traditional foundation compaction devices tend to tilt during the compaction process, causing unevenness on the foundation surface and resulting in poor flatness. Summary of the Invention

[0003] The purpose of this invention is to provide a foundation compaction device for airport construction. The device drives the drive gear to rotate, and two first sector gears alternately mesh with their corresponding first racks, so that a pair of first sector gears can continuously drive the first moving rod to move up and down, thereby driving the compaction pile to move up and down continuously to compact the foundation. The guide plate ensures that the first moving rod can only move up and down, so the compaction pile will not tilt during the up and down movement.

[0004] To achieve these objectives and other advantages of the present invention, an airport construction foundation compaction device is provided, comprising:

[0005] The base has a tamping groove on it;

[0006] tamping piles;

[0007] The support column is vertically installed on the base. The support column is hollow inside and open at the bottom. The inside of the support column is opposite to the compaction opening.

[0008] The drive gear is vertically mounted inside the support column and rotates under the drive of the power unit;

[0009] A pair of first driven gears are symmetrically arranged on both sides of the driving gear and mesh with the driving gear respectively. When the driving gear rotates, the pair of first driven gears rotate synchronously.

[0010] A pair of first sector gears are respectively fixed on a pair of first driven gears. The pair of first driven gears can drive their corresponding first sector gears to rotate synchronously and coaxially.

[0011] The first movable rod is vertically arranged and opposite to the driving gear, and located between the pair of first sector gears. The bottom of the first movable rod is connected to the tamping pile. The upper part of the first movable rod is provided with a pair of first racks. The pair of first racks are symmetrically arranged relative to the first movable rod and correspond to the pair of first sector gears respectively. When the power device drives the driving gear to rotate, the pair of first sector gears alternately mesh with their corresponding first racks, so that the pair of first sector gears can continuously drive the first movable rod to move up and down, thereby driving the tamping pile to move up and down continuously, and the tamping pile can pass through the tamping opening when it is downward.

[0012] At least two guide plates are fixed inside the support column, and a first moving rod passes through the at least two guide plates. None of the guide plates restricts the first moving rod and the rammed pile from moving up and down.

[0013] In another technical solution, the airport construction foundation compaction equipment includes two guide plates, which are vertically spaced between a pair of first racks and compaction piles. Each guide plate is horizontally positioned and its outer edge is fixed to the inner wall of the support column.

[0014] In another technical solution, the airport construction foundation compaction equipment further includes:

[0015] Two second moving rods are symmetrically arranged relative to the first moving rod and are both vertically arranged. The two second moving rods pass through the at least two guide plates respectively. On the side of the two second moving rods opposite to the first moving rod, a second rack and a third rack are respectively arranged vertically at intervals. The at least two guide plates are located between the third rack and the compacted pile. The two second racks are respectively opposite to the two first racks. The two third racks are symmetrically arranged relative to the first moving rod and are always separated from the uppermost guide plate by a certain distance. The two second racks correspond to the two first sector gears respectively. When the power device drives the drive gear to rotate, the pair of first sector gears can alternately mesh with their corresponding first rack and second rack respectively.

[0016] A pair of second driven gears are respectively disposed below a pair of first driven gears and mesh with their respective first driven gears, and are symmetrically arranged relative to the first moving rod;

[0017] A pair of second sector gears are fixed on a pair of second driven gears. The pair of second driven gears can drive their corresponding second sector gears to rotate synchronously and coaxially. When the power device drives the driving gear to rotate, the two second sector gears can alternately mesh with their corresponding third racks. For any one of the first sector gears, when the first sector gear meshes with its corresponding first rack, the second sector gear below the first sector gear meshes with its corresponding third rack. When the first sector gear meshes with its corresponding second rack, the second sector gear below the first sector gear does not mesh with its corresponding third rack.

[0018] In another technical solution, in the airport construction foundation compaction equipment, the second rack and the third rack on each second moving rod are not on a straight line.

[0019] In another technical solution, the airport construction foundation compaction equipment has multiple casters at the bottom of the base.

[0020] In another technical solution, the power device in the airport construction foundation compaction equipment is an electric motor, which is fixed on a support column.

[0021] In another technical solution, the airport construction foundation compaction equipment further includes:

[0022] A connecting plate is horizontally installed inside the support column and located between the bottom guide plate and the compacted pile. A first moving rod and two second moving rods pass through the connecting plate and are fixedly connected to it. The connecting plate does not interfere with the up-and-down movement of the first moving rod and the two second moving rods.

[0023] In another technical solution, the airport construction foundation compaction equipment further includes:

[0024] Multiple connecting rods are spaced apart between the connecting plate and the rammed pile, with both ends of each connecting rod fixedly connected to the connecting plate and the rammed pile, respectively.

[0025] In another technical solution, each connecting rod in the airport construction foundation compaction equipment is set vertically.

[0026] In another technical solution, in the airport construction foundation compaction equipment, springs are fitted on the first moving rod and the two second moving rods. The springs are located between the bottom guide plate and the connecting plate, and each spring is always in a compressed state during the up and down movement of the first moving rod and the two second moving rods.

[0027] The present invention has at least the following beneficial effects:

[0028] This invention uses a power device to drive a drive gear to rotate, which in turn drives a pair of first driven gears to rotate. The pair of first driven gears then drive a pair of first sector gears to rotate. As the pair of first sector gears rotate, they continuously mesh with their corresponding first racks, allowing the pair of first sector gears to continuously drive the first moving rod to move up and down. This, in turn, drives the compacted pile to move up and down continuously, and compacts the foundation when it moves downward. The guide plate ensures that the first moving rod can only move up and down, so the compacted pile will not tilt during its up and down movement.

[0029] The first movable rod and two second movable rods of the present invention can move downwards simultaneously, making the compaction of the foundation by the tamping pile more uniform.

[0030] The present invention incorporates springs on the first moving rod and the two second moving rods. The springs can add a downward elastic force to the tamping pile, thereby increasing the tamping strength. Furthermore, when the tamping pile is compacting the ground, the springs can buffer the upward reaction force of the tamping pile, reducing noise and preventing damage to the device.

[0031] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0032] Figure 1 This is a structural schematic diagram of an airport construction foundation compaction device according to an embodiment of the present invention. Detailed Implementation

[0033] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0034] It should be noted that in the description of this invention, the terms "lateral", "longitudinal", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0035] like Figure 1 As shown, the present invention provides an airport construction foundation compaction device, comprising:

[0036] Base 1, on which a compaction opening 101 is provided;

[0037] 2 compacted piles;

[0038] The support column 3 is vertically installed on the base 1. The support column 3 is hollow inside and open at the bottom. The inside of the support column 3 is opposite to the tamping opening 101.

[0039] The drive gear 4 is vertically mounted inside the support column 3 and rotates under the drive of the power unit, such as... Figure 1 As shown, the driving gear 4, a pair of first driven gears 5, a pair of first sector gears 6, a pair of second driven gears 10, and a pair of second sector gears 11 all rotate in the vertical plane;

[0040] A pair of first driven gears 5 are symmetrically arranged on both sides of the driving gear 4 and mesh with the driving gear 4 respectively. When the driving gear 4 rotates, it drives the pair of first driven gears 5 to rotate synchronously.

[0041] A pair of first sector gears 6 are respectively fixed on a pair of first driven gears 5. The pair of first sector gears 6 are parallel to their corresponding first driven gears 5. The pair of first driven gears 5 can drive their corresponding first sector gears 6 to rotate synchronously and coaxially.

[0042] The first moving rod 7 is vertically arranged and opposite to the driving gear 4, located between the pair of first sector gears 6. The bottom of the first moving rod 7 is connected to the compacted pile 2. A pair of first racks 701 are arranged symmetrically with respect to the first moving rod 7 and correspond to the pair of first sector gears 6 respectively. When the power device drives the driving gear 4 to rotate, the pair of first sector gears 6 alternately mesh with their corresponding first racks 701. That is, when one first sector gear 6 meshes with its corresponding first rack 701, the other first sector gear 6 does not mesh with its corresponding first rack 701. Furthermore, when the other first sector gear 6 meshes with its corresponding first rack 701, the first first sector gear 6 does not mesh with its corresponding first rack 701. Specifically, as shown... Figure 1 As shown, when the first sector gear 6 on the left and the first rack 701 on the left are engaged, the first sector gear 6 on the right and the first rack 701 on the right are not engaged. When the first sector gear 6 on the right and the first rack 701 on the right are engaged, the first sector gear 6 on the left and the first rack 701 on the left are not engaged, so that a pair of first sector gears 6 can continuously drive the first moving rod 7 to move up and down, thereby driving the compacted pile 2 to move up and down continuously, and the compacted pile 2 can pass through the compaction opening 101 when it is downward.

[0043] At least two guide plates 8 are fixed inside the support column 3. The first moving rod 7 passes through the at least two guide plates 8, but is not fixed to the at least two guide plates 8. Each guide plate 8 does not restrict the first moving rod 7 and the rammed pile 2 from moving up and down.

[0044] The airport construction foundation compaction equipment provided in this solution, when in use, drives the drive gear 4 to rotate through the power unit. The drive gear 4 drives a pair of first driven gears 5 to rotate. The pair of first driven gears 5 respectively drive a pair of first sector gears 6 to rotate. When the pair of first sector gears 6 rotate, they continuously mesh with their corresponding first racks 701, so that the pair of first sector gears 6 can continuously drive the first moving rod 7 to move up and down, thereby driving the compaction pile 2 to move up and down continuously. When moving downward, it compacts the foundation. The guide plate 8 ensures that the first moving rod 7 can only move up and down, so the compaction pile 2 will not tilt during the up and down movement.

[0045] In another technical solution, the airport construction foundation compaction equipment includes two guide plates 8, which are vertically spaced between a pair of first racks 701 and the compaction piles 2. Each guide plate 8 is horizontally positioned, and its outer edge is fixed to the inner wall of the support column 3. By using two guide plates 8, the first moving rod 7 can only move up and down.

[0046] In another technical solution, the airport construction foundation compaction equipment further includes:

[0047] Two second moving rods 9 are symmetrically arranged relative to the first moving rod 7 and are both vertically positioned. Each of the two second moving rods 9 passes through at least two guide plates 8 but is not fixed to them. On the side of each of the two second moving rods 9 opposite to the first moving rod 7, a second rack 901 and a third rack 902 are respectively arranged vertically at intervals. The at least two guide plates are located between the two third racks and the compacted pile. The two second racks 901 are respectively opposite to the two first racks 701. The two third racks 902 are symmetrically arranged relative to the first moving rod and are always aligned with the uppermost one. Guide plates 8 are spaced a certain distance apart. Two second racks 901 correspond to two first sector gears 6 respectively. When the power device drives the drive gear 4 to rotate, a pair of first sector gears 6 can alternately mesh with their corresponding first racks 701 and second racks 901. That is, when one first sector gear 6 meshes with its corresponding first rack 701, the other first sector gear 6 meshes with its corresponding second rack 901. Furthermore, when the other first sector gear 6 meshes with its corresponding first rack 701, the first first sector gear 6 meshes with its corresponding second rack 901. Specifically, as shown... Figure 1As shown, when the first sector gear 6 on the left and the first rack 701 on the left are engaged, the first sector gear 6 on the right and the second rack 901 on the second moving rod 9 on the right are engaged, and when the first sector gear 6 on the right and the first rack 701 on the right are engaged, the first sector gear 6 on the left and the second rack 901 on the second moving rod 9 on the left are engaged.

[0048] A pair of second driven gears 10 are respectively disposed below a pair of first driven gears 5 and respectively mesh with the corresponding first driven gears 5, and are symmetrically arranged relative to the first moving rod 7;

[0049] A pair of second sector gears 11 are respectively fixed on a pair of second driven gears 10. The pair of second sector gears 11 are parallel to their corresponding second driven gears 10. When the pair of second driven gears 10 rotate, they can drive their corresponding second sector gears 11 to rotate synchronously and coaxially. When the power device drives the driving gear 4 to rotate, the driving gear 4 drives a pair of first driven gears 5 to rotate synchronously. The pair of first driven gears 5 drive a pair of second driven gears 10 to rotate synchronously. When the pair of second driven gears 10 rotate, they can drive their corresponding second sector gears 11 to rotate synchronously. The pair of second sector gears 11 can alternately mesh with their corresponding third racks 902. That is, when one second sector gear 11 meshes with its corresponding third rack 902, the other second sector gear 11 does not mesh with its corresponding third rack 902. And when the other second sector gear 11 meshes with its corresponding third rack 902, the first second sector gear 11 does not mesh with its corresponding third rack 902. Specifically, as shown... Figure 1 As shown, when the second sector gear 11 on the left and the third rack 902 on the left are engaged, the second sector gear 11 on the right and the third rack 902 on the right are not engaged. When the second sector gear 11 on the right and the third rack 902 on the right are engaged, the second sector gear 11 on the left and the third rack 902 on the left are not engaged. For any first sector gear 6, when the first sector gear 6 and its corresponding first rack 701 are engaged, the second sector gear 11 below the first sector gear 6 and its corresponding third rack 902 are engaged. When the first sector gear 6 and its corresponding second rack 901 are engaged, the second sector gear 11 below the first sector gear 6 and its corresponding third rack 902 are not engaged.

[0050] The airport construction foundation compaction equipment provided in this solution, such as... Figure 1As shown, in use, the power unit drives the driving gear 4 to rotate counterclockwise, which in turn drives a pair of first driven gears 5 to rotate clockwise. The pair of first driven gears 5 then drive a pair of second driven gears 10 to rotate counterclockwise and a pair of first sector gears 6 to rotate clockwise. When the pair of second driven gears 10 rotate, they drive their corresponding second sector gears 11 to rotate counterclockwise. Figure 1 As shown, when the first sector gear 6 on the left and the first rack 701 on the left are engaged, the first sector gear 6 on the right and the second rack 901 on the second moving rod 9 on the right are engaged, the second sector gear 11 on the left and the third rack 902 on the second moving rod 9 on the left are engaged, and the second sector gear 11 on the right and the third rack 902 on the second moving rod 9 on the right are not engaged, the first sector gear 6 on the left drives the first moving rod 7 to move downward, the first sector gear 6 on the right drives the second moving rod 9 on the right to move downward, and at the same time, the second sector gear 11 on the left drives the second moving rod 9 on the left to move downward, thereby driving the compacted pile 2 to move downward and compacting the foundation as it moves downward. Because the first moving rod 7 in the middle and the two second moving rods 9 on both sides move downward synchronously during compaction, the compaction of the foundation by the compacted pile 2 is more uniform. After the foundation is compacted, the first sector gear 6 on the left engages with the second rack 901 on the second moving rod 9 on the left, causing the second moving rod 9 on the left to move upward. The first sector gear 6 on the right engages with the first rack 701 on the right, causing the first moving rod 7 to move upward. At the same time, the second sector gear 11 on the right engages with the third rack 902 on the second moving rod 9 on the right, causing the second moving rod 9 on the right to move upward, thereby causing the compacted pile 2 to move upward.

[0051] In another technical solution, in the airport construction foundation compaction equipment, the second rack 901 and the third rack 902 on each of the second moving rods 9 are not on a straight line. Thus, when the second sector gear 11 is not meshing with the third rack 902, it will not mesh with the first rack 701. During foundation compaction, the first sector gear 6 on the left drives the first moving rod 7 downwards, and the first sector gear 6 on the right drives the second moving rod 9 on the right downwards. Simultaneously, the second sector gear 11 on the left drives the second moving rod 9 on the left downwards, thus compacting the foundation with the compacted pile 2. After the foundation is compacted, the first sector gear 6 on the left drives the second moving rod 9 on the left upwards, and the first sector gear 6 on the right drives the first moving rod 7 upwards. Simultaneously, the second sector gear 11 on the right drives the second moving rod 9 on the right upwards, thereby moving the compacted pile 2 upwards. The first moving rod 7 and the two second moving rods 9 move synchronously.

[0052] like Figure 1 As shown, the vertical downward arrow indicates that the first moving rod 7 and the two second moving rods 9 are moving downwards at this time, and the other arrows indicate the rotation direction of the driving gear 4, the pair of first driven gears 5 and the pair of second driven gears 10 respectively.

[0053] In another technical solution, the base 1 of the airport construction foundation compaction equipment is provided with multiple casters at its bottom.

[0054] In another technical solution, the power device in the airport construction foundation compaction equipment is an electric motor, which is fixed on the support column 3.

[0055] In another technical solution, the airport construction foundation compaction equipment further includes:

[0056] The connecting plate 12 is horizontally set inside the support column 3 and is located between the bottom guide plate 8 and the compacted pile 2. The first moving rod 7 and two second moving rods 9 pass through the connecting plate 12 and are fixedly connected to the connecting plate 12. The connecting plate 12 does not interfere with the up and down movement of the first moving rod 7 and the two second moving rods 9.

[0057] In another technical solution, the airport construction foundation compaction equipment further includes:

[0058] Multiple connecting rods 13 are spaced apart between the connecting plate 12 and the compacted pile 2, with both ends of each connecting rod 13 fixedly connected to the connecting plate 12 and the compacted pile 2, respectively. By setting the connecting rods 13, the force on the first moving rod 7 and the two second moving rods 9 can be evenly transmitted to the compacted pile 2.

[0059] In another technical solution, each connecting rod 13 in the airport construction foundation compaction equipment is set vertically.

[0060] In another technical solution, in the airport construction foundation compaction equipment, springs are fitted on the first moving rod 7 and the two second moving rods 9. The springs are located between the bottom guide plate 8 and the connecting plate 12, and each spring is always in a compressed state during the up-and-down movement of the first moving rod 7 and the two second moving rods 9. By fitting springs on the first moving rod 7 and the two second moving rods 9, the springs can add a downward elastic force to the compaction pile 2, thereby increasing the compaction strength. Furthermore, when the compaction pile 2 compacts the ground, the springs can buffer the upward reaction force of the compaction pile 2, reducing noise and preventing damage to the device.

[0061] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
