Description

Technical Field

[0001] The utility model relates to the technical field of ramming equipment, in particular to anti-vibration ramming equipment for large-area fine-grained soil fields. Background Art

[0002] In the field of modern engineering construction, especially in projects involving the treatment of fine-grained soil (such as clay, silt, etc.), it is often difficult to meet the project's requirements for foundation bearing capacity and deformation control without effective treatment. Therefore, it is necessary to compact the fine-grained soil field with ramming equipment.

[0003] The utility model patent with application number CN202123261425.2 discloses a ramming device for land consolidation, which includes a car plate, a ramming hole is opened in the car plate, four columns are fixedly installed in the ramming hole, guide wheels are rotatably installed in the four columns, and a slider is slidably installed in the guide wheels. A top plate is fixedly installed on the upper wall of the four columns, a motor frame is fixedly installed on the wall of the top plate, a first motor is fixedly installed on the upper wall of the motor frame, a driving gear is fixedly installed on the driving end of the first motor, a main shaft is rotatably installed in the motor frame, and a driven gear is fixedly installed on the main shaft The driving gear is meshed with the driven gear, and a turntable is fixedly installed at both ends of the main shaft, and a connecting rod is hinged on the turntable. The other end of the connecting rod is hinged to the wall surfaces of both sides of the slider. The driven bevel gear is rotatably installed on the upper wall surface of the slider, and the driving bevel gear is rotatably installed on the front wall surface of the slider. The driving bevel gear is meshed with the driven bevel gear, and the driving bevel gear is fixedly installed with an adjusting disk through the side wall of the slider, and a threaded rod is fixedly installed on the lower wall surface of the driven gear. An adjusting hammer is slidably installed in the slider, and a thread is opened in the adjusting hammer. The adjusting hammer is threadedly connected to the threaded rod, and a ramming hammer is fixedly installed on the lower wall surface of the adjusting hammer. The support foot device driven by the cylinder improves the stability of the ramming work and prevents movement such as slipping. The motor is used as the prime mover of the ramming part and operates continuously to improve the stability of the ramming work. Compared with the traditional structure, it is easier to control and more efficient. Through the gear set and crank slider mechanism, the ramming speed and soil density are maintained uniform during the operation of the ramming equipment. The height of the ramming hammer can be adjusted to meet the ramming needs of different lands.

[0004] Although the ramming equipment for land consolidation can adapt to the ramming needs of different lands, the device still has the following problems in actual use: the device only compacts the soil through the set ramming hammer, and the contact area between the ramming hammer and the ground is limited, resulting in a small single ramming area, making the ramming efficiency low and not suitable for soil compaction in a large area. In view of this, we propose a large-area fine-grained soil field anti-vibration ramming equipment. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a large-area fine-grained soil field anti-vibration tamping device.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] The anti-seismic tamping equipment for large-scale fine-grained soil fields includes two symmetrical fixed plates, four connecting rods are fixed between the two fixed plates, and a screw rod is threadedly connected to the center of the fixed plate at the top;

[0009] A ramming assembly is installed in the opening of the connecting frame, and the ramming assembly includes a supporting plate passing through the opening of the connecting frame. A strip groove is opened at the center of the supporting plate, and a rotating shaft is rotatably installed in the strip groove. A plurality of eccentric blocks are keyed to the strip groove, and a motor for driving the rotating shaft to rotate is installed on the front end surface of the supporting plate; the bottom of the supporting plate is fixed with downwardly extending fixing seats at the left and right ends, and a ramming seat is fixed to the bottom of the fixing seat.

[0010] Furthermore, ear plates are fixed at the four corners of the bottom of the fixed plate located below, a connecting shaft is rotatably installed between the two ear plates, and both ends of the connecting shaft are coaxially keyed to the wheel body.

[0011] Furthermore, the cross-section of the rammed earth seat is trapezoidal, and the rammed earth seat is made of galvanized steel.

[0012] Furthermore, the rear end surface of the connecting frame is fixedly connected to a push handle by means of bolts, and the rear end of the push handle is sleeved with a shock-absorbing sleeve made of rubber.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] This embodiment provides a technical solution:

[0029] See also Figure 1-Figure 4As shown, the large-area fine-grained soil field anti-seismic tamping equipment includes two symmetrical fixed plates 1, four connecting rods 10 are fixed between the two fixed plates 1, and a screw rod 11 is threadedly connected to the center of the fixed plate 1 at the top; a connecting frame 2 is installed between the two fixed plates 1, the connecting rod 10 passes through the connecting frame 2 and is slidably connected to the connecting frame 2, and the bottom end of the screw rod 11 is rotatably connected to the top end of the connecting frame 2; guide rods 20 are fixed near the four corners of the opening of the connecting frame 2, and springs 21 are sleeved on the upper and lower sides of the guide rod 20. ; A ramming assembly 3 is installed in the opening of the connecting frame 2, and the ramming assembly 3 includes a supporting plate 30 passing through the opening of the connecting frame 2. A strip groove 301 is opened at the center of the supporting plate 30, and a rotating shaft 31 is rotatably installed in the strip groove 301. A plurality of eccentric blocks 32 are keyed to the strip groove 301, and a motor 33 for driving the rotating shaft 31 to rotate is installed on the front end surface of the supporting plate 30; the bottom of the supporting plate 30 is fixed with downwardly extending fixing seats 35 at the left and right ends, and a ramming seat 34 is fixed to the bottom of the fixing seat 35.

[0030] Furthermore, ear plates 13 are fixed to the four corners of the bottom of the fixed plate 1 at the bottom. A connecting shaft 14 is rotatably mounted between the two ear plates 13. Both ends of the connecting shaft 14 are coaxially keyed to a wheel body 15. The design of the wheel body 15 allows the entire device to be easily moved, facilitating transfer between fine-grained soil sites for tamping operations.

[0031] Furthermore, the ramming base 34 has a trapezoidal cross-section and is made of galvanized steel. This trapezoidal cross-section helps to better disperse the impact force during the tamping process, improving tamping efficiency while also reducing soil rebound, ensuring a more uniform and deep compaction effect. The galvanized steel material used for the ramming base 34 offers excellent corrosion and wear resistance, extending the life of the equipment.

[0032] Furthermore, a push handle 22 is bolted to the rear end of the connecting frame 2. A rubber shock-absorbing sleeve 23 is mounted on the rear end of the push handle 22. The push handle 22 allows the operator to easily push the device, improving operational convenience. The rubber shock-absorbing sleeve 23 effectively absorbs vibrations during operation, reducing hand fatigue and enhancing working comfort.

[0033] Furthermore, a hand wheel 12 is provided at the top end of the screw rod 11, and the screw rod 11 is coaxially keyed with the hand wheel 12. The screw rod 11 can be adjusted by rotating the hand wheel 12, which has the advantage of convenient operation.

[0034] Furthermore, the cross-section of the connecting frame 2 is in the shape of a square, and the guide rod 20 is fixedly connected to the inner wall of the connecting frame 2 by bolts. The square design ensures the overall stability and reliability of the equipment structure, and the bolt fixing method ensures the installation stability of the guide rod 20.

[0035] Furthermore, inclined braces 36 are provided on both sides of the fixing seat 35, and the inclined braces 36 are fixedly connected to the rammed earth seat 34 and the bearing plate 30 by bolts. The inclined braces 36 increase the connection strength between the rammed earth seat 34 and the bearing plate 30, ensuring the stable use of the rammed earth seat 34.

[0036] It should be added that the cross-section of the strip groove 301 in this embodiment is rectangular. When the rotating shaft 31 drives the eccentric block 32 to rotate, the rotation of the eccentric block 32 will not be hindered by the strip groove 301, thereby facilitating the continuous reciprocating lifting motion of the supporting plate 30.

[0037] It is worth noting that the motor 33 involved in this embodiment is an existing conventional technology and will not be described in detail here.

[0038] During specific use, the user first turns on the power of the motor 33, and the motor 33 starts to work. The output shaft of the motor 33 rotates to drive the rotating shaft 31 and multiple eccentric blocks 32 to rotate. As the eccentric blocks 32 rotate, the supporting plate 30 continues to move back and forth. The supporting plate 30 also drives the fixed seats 35 and the ramming seats 34 on both sides to move back and forth. The ramming seats 34 simultaneously ram the soil of the fine-grained soil field back and forth. At this time, the staff can push the device to move so that the ramming seats 34 can continue to ram a large area of fine-grained soil.

[0039] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
