Description

Technical Field

[0001] This utility model relates to the field of soft soil foundation reinforcement technology, and in particular to a soft soil foundation reinforcement treatment device for building construction. Background Technology

[0002] Soft soil foundation reinforcement in building construction refers to the treatment of natural soft soil foundations (soil layers with characteristics such as high water content, high compressibility, low strength, and poor permeability) during the construction process. This aims to improve the foundation's bearing capacity, reduce settlement, enhance stability, meet the foundation requirements of building projects, and ensure the safety and stability of structures. In some construction sites, dynamic compaction machines are used for soft soil foundation reinforcement. These machines utilize the enormous impact energy generated by the free fall of a heavy hammer to rearrange soft soil particles and expel pore water, thereby increasing the foundation's bearing capacity and reducing compressibility.

[0003] In existing dynamic compaction machines, when using hammers to reinforce soft soil foundations, the hammers typically require bolts to be used to assemble a counterweight hammer body to increase their weight. However, these bolts are prone to loosening during connection. Although some hammers use wedge nuts combined with locking washers to prevent loosening, material fatigue and deformation of the wedge nuts and washers may occur during repeated hammer impacts, compromising the safe use of the counterweighted hammer. Therefore, we propose a soft soil foundation reinforcement device for building construction. Utility Model Content

[0004] The main objective of this invention is to provide a soft soil foundation reinforcement device for building construction. By installing a locking mechanism at the counterweight hammer plate above the tamping hammer base, the long cylindrical nut of the locking mechanism is screwed and locked at the side bolt and center bolt of the counterweight hammer plate. The buffer ring and pressure ring of the locking mechanism can lock the long cylindrical nut at the side bolt for groove-limited locking and anti-loosening. Furthermore, the long cylindrical nut at the hanger can be locked by the L-shaped inner locking plate for groove-limited locking and anti-loosening, preventing the long cylindrical nut from loosening during the tamping hammer impact. Simultaneously, the U-shaped rib pins and locks the L-shaped inner locking plate to the fixed column, preventing the L-shaped inner locking plate, buffer ring, and pressure ring from being thrown out. This effectively solves the problem of easy loosening of traditional connecting bolt structures at the tamping hammer. Moreover, the buffer ring, in conjunction with the vertical protective ring, can prevent the pressure ring from contacting and wearing with the counterweight hammer plate. The rubber material also provides a buffering effect, extending the service life of the components and effectively solving the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A soft soil foundation reinforcement device for building construction includes a tamping hammer base plate, a counterweight hammer plate, and a hanger. The counterweight hammer plate is stacked on top of the tamping hammer base plate, and a hanger is fixed to the center of the surface of the uppermost counterweight hammer plate. Side bolts and a center bolt are fixed to the surface of the tamping hammer base plate for passing through the counterweight hammer plate and the hanger, respectively. The device also includes a locking mechanism, which comprises a long cylindrical nut, a buffer ring, a pressure ring, an L-shaped inner locking plate, a fixed column, and a U-shaped rib. The side bolts and the center bolt... The bolts are screwed with long cylindrical nuts at the bolt bodies that pass through the counterweight hammer disc and the hanger, and a buffer ring and a pressure ring are superimposed and covered at the long cylindrical nuts above the side bolts. An L-shaped inner locking plate is fixed on the inner ring wall of the pressure ring to lock the long cylindrical nuts above the center bolt, and a fixed hole for locking the fixed column is opened at the plate body of the L-shaped inner locking plate near the pressure ring. The fixed column is welded and fixed to the surface of the uppermost disc body of the counterweight hammer disc, and a through hole for inserting U-shaped ribs is opened at the column body of the fixed column that passes through the fixed hole.

[0007] Furthermore, the bottom of the hexagonal cylindrical tube of the long cylindrical nut is integrally formed with a pressure ring, and a threaded hole is provided through the hexagonal cylindrical tube of the long cylindrical nut and the pressure ring;

[0008] By adopting the above technical solution, the hexagonal barrel of the long barrel nut and the pressure ring can be screwed together at the center bolt and the side bolt. Then, the pressure ring of the long barrel nut can be firmly pressed onto the surface of the uppermost plate of the counterweight hammer disk to increase the friction contact area.

[0009] Furthermore, the L-shaped inner locking plate is welded in four sets in a ring-shaped distributed manner inside the pressure ring, and the ends of the four sets of plates away from the pressure ring of the L-shaped inner locking plate are provided with hexagonal notches for clamping long cylindrical nuts.

[0010] By adopting the above technical solution, the four sets of L-shaped inner locking plates inside the pressure ring can be locked onto the long cylindrical nut above the center bolt by means of hexagonal notches.

[0011] Furthermore, the surfaces of the buffer ring and the pressure ring are provided with hexagonal grooves, and a long cylindrical nut above the side bolt extends out of the hexagonal groove.

[0012] By adopting the above technical solution, the hexagonal grooves of the buffer ring and the pressure ring can be engaged with the long cylindrical nut, so that the pressure ring restricts the reverse loosening of the long cylindrical nut above the side bolt with the hexagonal groove.

[0013] Furthermore, the diameter of the perforated hole is larger than the diameter of the U-shaped rib, and the two ends of the U-shaped rib bend downward on both sides of the fixed column;

[0014] By adopting the above technical solution, after the U-shaped rib passes through the hole in its straight rib state, the straight ribs of the U-shaped ribs on both sides of the hole can be bent downwards, so that the U-shaped ribs prevent the L-shaped inner locking plate and the pressure ring from detaching upwards at the fixed column.

[0015] Furthermore, the buffer ring has an integrally formed vertical guard ring on its ring edge that is sleeved outside the pressure ring, and the buffer ring and the vertical guard ring press against the surface of the counterweight disk.

[0016] By adopting the above technical solution, the buffer ring and the vertical guard ring can protect the pressure ring and prevent the pressure ring from contacting and rubbing against the uppermost plate of the counterweight hammer disc.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model provides a locking mechanism at the counterweight hammer plate above the tamping hammer base. After the long cylindrical nut of the locking mechanism is screwed and locked at the side bolt and center bolt of the counterweight hammer plate, the buffer fixed ring and the pressure fixed ring of the locking mechanism can lock the long cylindrical nut at the side bolt for groove limiting and preventing loosening. The long cylindrical nut at the hanger can be locked by the L-shaped inner locking plate for groove limiting and preventing loosening, thus preventing the long cylindrical nut from loosening during the impact of the tamping hammer. At the same time, the U-shaped rib pins and locks the L-shaped inner locking plate to the fixed column, preventing the L-shaped inner locking plate, buffer fixed ring and pressure fixed ring from being thrown out. This effectively solves the problem of easy loosening of the traditional connecting bolt structure at the tamping hammer.

[0019] Furthermore, the buffer ring, in conjunction with the vertical guard ring, can prevent the pressure ring from contacting and wearing with the counterweight hammer disc. The rubber material can also play a buffering role, extending the service life of the components. During disassembly, simply use hydraulic pliers to cut off the bent rib on one side of the U-shaped rib, and the remaining straight rib can be easily pulled out, thereby easily pulling up the relevant components and disassembling the long cylinder nut, realizing convenient disassembly of the ramming hammer base plate and the counterweight hammer disc. The operation is simple and efficient. Attached Figure Description

The device also includes a locking mechanism 6, which includes a long cylindrical nut 7, a buffer ring 8, a pressure ring 9, an L-shaped inner locking plate 12, a fixed column 14, and a U-shaped rib 16. The side bolts 5 and the center bolt 4... Long cylindrical nuts 7 are screwed onto the bolts that pass through the counterweight hammer disc 2 and the hanger 3 respectively. A buffer ring 8 and a pressure ring 9 are superimposed and covered at the long cylindrical nut 7 above the side bolt 5. An L-shaped inner locking plate 12 for locking the long cylindrical nut 7 above the center bolt 4 is fixed on the inner ring wall of the pressure ring 9. A fixing hole 13 for locking the fixing column 14 is opened at the plate body of the L-shaped inner locking plate 12 near the pressure ring 9. The fixing column 14 is welded and fixed to the surface of the uppermost disc of the counterweight hammer disc 2. A through hole 15 for inserting a U-shaped rib 16 is opened at the column body of the fixing column 14 that passes through the fixing hole 13.

[0026] The long cylindrical nut 7 has a pressure ring integrally formed at the bottom of its hexagonal cylindrical part, and a threaded hole is provided between the hexagonal cylindrical part and the pressure ring.

[0027] By adopting the above technical solution, the hexagonal long cylinder of the long cylinder nut 7 and the pressure ring can be screwed together at the center bolt 4 and the side bolt 5. Then, the pressure ring of the long cylinder nut 7 can be firmly pressed onto the uppermost disc surface of the counterweight hammer disk 2 to increase the friction contact area.

[0028] Among them, the L-shaped inner locking plate 12 is distributed in a ring and welded in four sets inside the pressure ring 9, and the ends of the four sets of plates of the L-shaped inner locking plate 12 away from the pressure ring 9 are provided with hexagonal notches 17 for clamping the long cylindrical nut 7.

[0029] By adopting the above technical solution, the four sets of L-shaped inner locking plates 12 inside the pressure ring 9 can be locked onto the long cylindrical nut 7 above the center bolt 4 by means of the hexagonal notch 17.

[0030] Among them, the surfaces of the buffer ring 8 and the pressure ring 9 are provided with a hexagonal groove 10, and a long cylindrical nut 7 above the side bolt 5 is passed through the hexagonal groove 10.

[0031] By adopting the above technical solution, the hexagonal groove 10 of the buffer ring 8 and the pressure ring 9 can be inserted into the long cylindrical nut 7, so that the pressure ring 9 restricts the reverse loosening of the long cylindrical nut 7 above the side bolt 5 with the hexagonal groove 10.

[0032] Wherein, the diameter of the hole 15 is larger than the diameter of the U-shaped rib 16, and the two ends of the U-shaped rib 16 bend downward on both sides of the fixed column 14.

[0033] By adopting the above technical solution, after the U-shaped rib 16 passes through the perforation 15 in the straight rib state, the straight ribs of the U-shaped rib 16 on both sides of the perforation 15 can be bent downwards, so that the U-shaped rib 16 prevents the L-shaped inner locking plate 12 and the pressure ring 9 from detaching upwards at the fixed column 14.

[0034] Among them, the buffer ring 8 has a vertical guard ring 11 integrally formed on the edge of the ring body, which is sleeved on the outside of the pressure ring 9, and the buffer ring 8 and the vertical guard ring 11 are pressed on the surface of the counterweight disk 2.

[0035] By adopting the above technical solution, the buffer ring 8, together with the vertical guard ring 11, can protect the pressure ring 9, preventing the pressure ring 9 from contacting and rubbing against the uppermost disc of the counterweight hammer disc 2.

[0036] It should be noted that this utility model is a soft soil foundation reinforcement device for building construction. A locking mechanism 6 is installed at the counterweight hammer disc 2 above the tamping hammer base 1. After the multi-layered disc body of the counterweight hammer disc 2 is assembled with the side bolts 5 and the center bolt 4 on the tamping hammer base 1, the counterweight hammer disc 2, which is fixed to the uppermost layer with the hanger 3, can also be secured at the side bolts 5 and the center bolt 4. Subsequently, a long cylindrical nut 7 can be screwed onto the center bolt 4 and the side bolt 5 protruding from the hanger 3 and the counterweight hammer disc 2. The buffer ring 8 and the pressure ring 9 are secured by a hexagonal... The groove 10 can be locked and positioned at the long cylindrical nut 7 at the side bolt 5. At this time, the L-shaped inner locking plate 12 is locked and positioned at the long cylindrical nut 7 at the center bolt 4 with the hexagonal notch 17. The fixed hole 13 of the L-shaped inner locking plate 12 can pass through the fixed post 14. At the same time, the buffer ring 8 and the vertical guard ring 11 can protect between the pressure ring 9 and the counterweight hammer 2. The rubber buffer ring 8 and the vertical guard ring 11 can play a material buffering role, so that the pressure ring 9 and the counterweight hammer 2 are not easy to contact and wear. Then the U-shaped rib 16 is in the straight After passing through the perforation 15 in the reinforced state, the straight ribs of the U-shaped ribs 16 on both sides of the perforation 15 can be bent downwards, so that the U-shaped ribs 16 prevent the L-shaped inner locking plate 12 and the pressure ring 9 from detaching upwards at the fixed column 14. Then, the hanger 3 can be normally clamped at the lifting clamp of the dynamic compaction machine for lifting and release, so that the hammer composed of the hammer base plate 1 and the counterweight hammer plate 2 can impact the soft soil foundation downwards for reinforcement. When the hammer is under force, the long cylindrical nut 7 will also be under force. At this time, the L-shaped inner locking plate 12 and the side bolt 5 are respectively located at the center bolt 4 and the side bolt 5. The pressure ring 9 is used to limit the groove and prevent loosening. At the same time, the L-shaped inner locking plate 12 and the pressure ring 9 are restricted by the U-shaped rib 16 at the fixed column 14, making them difficult to be thrown out. When it is necessary to disassemble the ramming hammer base plate 1 and the counterweight hammer plate 2, it is only necessary to use hydraulic pliers to cut off one side of the bent rib of the U-shaped rib 16, so that the remaining straight rib can be easily pulled out of the through hole 15. Then the pressure ring 9, the buffer ring 8 and the L-shaped inner locking plate 12 can be pulled up. Then the long cylindrical nut 7 can be removed with a wrench, and the ramming hammer base plate 1 and the counterweight hammer plate 2 can be disassembled.
