[0037] Such as Figures 1-3 , a foundation ramming device, comprising: a chassis 1, a fixed seat 2 and a ramming mechanism 3;

[0038] The fixed seat 2 is installed on the upper surface of the chassis 1; the chassis 1 is provided with a ramming opening 11; a plurality of rod lifting through grooves 12 are provided at multiple places of the fixed seat 2;

[0039] The ramming mechanism 3 comprises: a ramming plate 31, ramming rods 32, ramming pressing members 33, ramming springs 34 and a ramming driver 35;

[0040] The ramming plate 31 is limited in lifting on the fixed seat 2, and the ramming plate 31 descends to the ramming opening 11; the ramming rods 32 lift in the rod lifting through grooves 12, and a plurality of the ramming rods 32 are located at different positions of the ramming plate 31, and the lower ends of the ramming rods are connected to the ramming plate 31; the ramming pressing members 33 are installed at the upper ends of the ramming rods in a lifting and adjusting manner and are located above the surface of the fixed seat 2; the ramming springs 34 are sleeved on the ramming rods 32 and are located between the upper surface of the fixed seat 2 and the ramming pressing members 33; the lower ends of the ramming springs 34 abut against the upper surface of the fixed seat 2, and the upper ends of the ramming springs 34 support the ramming pressing members 33, so that the ramming plate 31 is suspended; the ramming driver 35 is installed on the fixed seat 2 and is used for driving the ramming plate 31 to elastically descend to the ramming opening 11.

[0041] This solution provides a foundation tamping device. A tamping spring 34 is arranged between the upper end of the tamping rod 32 and the upper surface of the fixed seat 2. The height position of the tamping pressure member 33 on the tamping rod 32 can be adjusted as needed, so that the distance between the tamping plate 31 and the tamping opening 11 can be adjusted, and the tamping height can be adjusted, solving the problem that the existing tamping device has a single function and cannot adjust the tamping height according to the actual situation.

[0042] Specifically, the chassis 1 is provided with a tamping opening 11, and the fixed seat 2 is installed on the chassis 1. The fixed seat 2 is used to fix the tamping mechanism 3; the fixed seat 2 is provided with a rod lifting through groove 12, and the tamping rod 32 is arranged in the rod lifting through groove 12 in a liftable manner. The lower end of the tamping rod 32 is connected to the tamping plate 31; the upper end of the tamping rod 32 extends upward out of the rod lifting through groove 12 and is connected to the tamping pressure member 33, that is, the tamping pressure member 33 is located above the surface of the fixed seat 2; the tamping spring 34 is sleeved on the tamping rod 32 and is located between the tamping pressure member 33 and the top surface of the fixed seat 2; in the initial state, the tamping spring 34 upwardly supports the tamping pressure member 33, and the upper end of the tamping rod 32 is connected to the tamping pressure member 33, so that the tamping plate 31 can be upwardly supported by the tamping rod 32; that is, in the initial state, the tamping plate 31 is away from the tamping opening 11 and the tamping plate 31 is in a suspended state; the tamping driver 35 is a mechanism known to have a driving and lifting function, such as a cylinder, an oil cylinder, etc., as long as it can drive the tamping plate 31 to move up and down. When it is necessary to tamp the foundation, the tamping driver 35 can be started. The tamping driver 35 drives the tamping plate 31 to move downward, and the tamping plate 31 drives the tamping rod 32 to move downward, thereby driving the tamping pressure member 33 on the tamping rod 32 to move downward. The tamping pressure member 33 presses the tamping spring 34 against the upper surface of the fixed seat 2, so that the tamping spring 34 elastically contracts, and the tamping plate 31 elastically presses down to the tamping opening 11, and the tamping plate 31 tampes the foundation at the tamping opening 11. At the same time, for the tamping pressure member 33 of this solution, its position on the tamping rod 32 can be adjusted up and down, that is, the height on the tamping rod 32 can be adjusted before tamping, so as to adjust the tamping height. For example, the farther the installation position of the tamping pressure member 33 is from the upper end of the tamping rod 32, the greater the distance between the tamping plate 31 and the tamping opening 11, and the smaller the tamping strength; the closer the installation position of the tamping pressure member 33 is to the upper end of the tamping rod 32, the smaller the distance between the tamping plate 31 and the tamping opening 11, and the greater the tamping strength. In this way, this solution can adjust the distance between the tamping plate 31 and the tamping opening 11, so as to adjust the tamping height, solving the problem that the existing tamping device has a single function and cannot adjust the tamping height according to the actual situation.

[0043] Optimally, a rod spacing 13 is formed between the inner wall of the rod lifting through groove 12 and the outer wall of the tamping rod 32.

[0044] The rod spacing 13 is arranged between the inner wall of the rod lifting through groove 12 and the outer wall of the ramming rod 32. That is, the ramming rod 32 generally does not contact the inner wall of the rod lifting through groove 12, which can increase the horizontal movement range of the ramming rod 32. When the ramming plate 31 has a tendency to move horizontally, the ramming rod 32 of the ramming plate 31 can be used to limit the horizontal movement in the rod lifting through groove 12, thereby offsetting the vibration of the horizontal tendency of the ramming plate 31 and improving the working stability of the foundation ramming device.

[0045] Optimally, the ramming press member 33 includes: a press member fixator 331 and a press disc 332;

[0046] The press member fixator 331 is installed above the press disc 332; the press member fixator 331 is installed on the ramming rod 32 in a lift-adjustable manner; the ramming spring 34 is located between the upper surface of the fixed seat 2 and the press disc 332; the outer diameter of the bottom surface of the press disc 332 is larger than the outer diameter of the ramming spring 34, and the upper end of the ramming spring 34 abuts against the bottom surface of the press disc 332.

[0047] The lift adjustment of the press member fixator 331 on the ramming rod 32 can drive the lift adjustment of the press disc 332. Based on the foundation that the ramming spring 34 keeps lifting the ramming press member 33 upward, the press member fixator 331 drives the lift adjustment of the ramming rod 32, thereby adjusting the height position of the ramming plate 31; since the outer diameter of the bottom surface of the press disc 332 is larger than the outer diameter of the ramming spring 34, the press disc 332 can fully contact the upper end of the ramming spring 34, which can make the force on the press disc 332 more uniform and the downward pressure stability higher.

[0048] Optimally, the ramming rod 32 is provided with an external thread structure;

[0049] The press member fixator 331 is provided with a press member nut 3311, the press member nut 3311 is in threaded fit with the ramming rod 32, a disc hollow opening 3321 is provided in the middle of the press disc 332, and the ramming rod 32 passes through the disc hollow opening 3321.

[0050] In this solution, it is preferably that the press member fixator 331 is provided with a press member nut 3311. When the press member nut 3311 is in threaded fit with the ramming rod 32, only by rotating and adjusting the press member fixator 331 can the press member nut 3311 be driven to rotate, so that the press member nut 3311 moves up and down relative to the ramming rod 32, driving the overall lift adjustment of the press member fixator 331 and driving the lift adjustment of the press disc 332, thereby adjusting the distance between the ramming plate 31 and the ramming opening 11. And a disc hollow opening 3321 is provided in the middle of the press disc 332, which can provide clearance for the lift of the ramming rod 32.

[0051] Optimally, a rubber pad 3322 is provided on the bottom surface of the press disc 332.

[0052] The rubber pad 3322 has a certain deformation ability and toughness, which can prevent the main body of the pressing disc 332 from directly contacting the ramming spring 34, thereby providing a buffering effect for the pressing disc 332 and preventing the pressing disc 332 from being damaged.

[0053] Optimally, the ramming driver 35 includes: a ramming drive motor 351 and a ramming cam 352;

[0054] The output end of the ramming drive motor 351 is connected to the ramming cam 352 for driving the ramming cam 352 to rotate; a convex surface 3521 protruding from the wheel surface is provided at a part of the ramming cam 352, and the ramming cam 352 contacts the ramming plate 31.

[0055] In this solution, it is preferably to use the ramming drive motor 351 to drive the ramming plate 31 to move up and down. Specifically, the ramming drive motor 351 drives the ramming cam 352 to rotate, and the rotation of the ramming cam 352 drives the rotation of its wheel surface. A convex surface 3521 protruding from the wheel surface is provided at a part of the ramming cam 352. Therefore, when the ramming cam 352 rotates, the convex surface 3521 will contact the ramming plate 31. Since the convex surface 3521 on the wheel surface is more prominent than other areas, when the ramming cam 352 contacts the ramming plate 31, the ramming cam 352 can drive the ramming plate 31 to move up and down.

[0056] Optimally, a driving block 311 is provided at the top of the ramming plate 31; the driving block 311 vertically passes through the fixed seat 2 and then contacts the ramming cam 352.

[0057] A driving block 311 can be provided at the top of the ramming plate 31. After the driving block 311 extends upward through the seat opening 21 of the fixed seat 2, the driving block 311 abuts against the wheel surface of the ramming cam 352; when the convex surface 3521 of the ramming cam 352 rotates to contact the driving block 311, the driving block 311 can be adjusted to move up and down, thereby driving the ramming plate 31 to move up and down, so as to ram the same area of the foundation multiple times in a cycle.

[0058] Optimally, it further includes: a push rod 4;

[0059] The push rod 4 is installed on the fixed seat 2 for driving the chassis 1 to move.

[0060] The construction worker can hold the push rod 4 by hand and push the fixed seat 2 to drive the chassis 1 to move, so as to move to different areas of the foundation and ram different positions of the foundation.

[0064] The angle positioning seats 5 are arranged in pairs on the same side of the fixed seat 2, that is, the fixed seat 2 is provided with a pair of angle positioning seats 5 on one side, and the fixed seat 2 can also be provided with paired angle positioning seats 5 on both sides; when the angle positioning seats 5 are arranged in pairs, the two angle positioning seats 5 are provided with positioning inclined surfaces 51 on the opposite sides facing each other, and the two positioning inclined surfaces 51 face different angles respectively; when the push rod 4 rotates on the fixed seat 2, it can abut against one of the positioning inclined surfaces 51, so as to position the push rod 4, so that the push rod 4 can be in an inclined angle in the default state and will not contact the ground, and it is also convenient for the construction personnel to use the positioning inclined surface 51 as a fulcrum to lift the front side of the chassis 1, so as to adjust the angle of the tamping plate 31.

[0065] Optimally, the front and rear sides of the chassis 1 are respectively provided with upwardly tilted support surfaces 14.
