Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a ramming machine for building construction. Background Technology
[0002] A ramming device according to Chinese patent document CN220318310U includes a drive mechanism, a steel rope, and a ramming hammer. The support device includes a telescopic frame and a support column. After being folded up, the volume occupied by the entire device can be reduced to a large extent. Moreover, the entire device eliminates the need for various hydraulic equipment or driving systems on large equipment, and the device can be reduced to a small ramming device. In this way, while meeting the requirements of small size, it can still use a ramming hammer for operation, which improves work efficiency to a certain extent compared with the current small ramming devices.
[0003] The aforementioned ramming device lacks a guide component when the hammer descends, so the hammer may deviate from its landing position. This not only affects the ramming effect, but the deviated hammer may also cause injury to workers, resulting in low safety. Utility Model Content

[0010] Preferably, a bidirectional lead screw is rotatably installed on the inner walls of both sides of the U-shaped transmission plate, and a moving block is threaded on the outer wall of the bidirectional lead screw. A guide crossbar is rotatably installed on the inner walls of both sides of the U-shaped transmission plate, and the guide crossbar and the moving block are slidably installed. An L-shaped lifting plate is fixedly installed at the bottom of the moving block.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The ramming machine for building construction, through the setting of the guide stabilizing rod, can guide the ramming plate during its descent, thus determining the landing point of the ramming plate after its descent. This not only ensures that the ramming plate lands accurately in the ramming position but also avoids the possibility of the ramming plate deviating and causing injury to workers, thereby improving the practicality of the device. Furthermore, through the setting of the drive motor, the L-shaped lifting plate can be moved.

A traction plate 4 is slidably installed on the outer wall of the guide stabilizer bar 3. A mounting post 5 is fixedly installed on the bottom of the traction plate 4. A rammed earth plate 6 is fixedly installed on the bottom of the mounting post 5. A traction bracket 20 is fixedly installed on one side of the support plate 2. A U-shaped connecting plate 7 is fixedly installed on the top of the traction plate 4. A U-shaped bracket 9 is fixedly installed on the top of the support plate 2. Traction wheels 10 are rotatably installed on the inner walls of both sides of the U-shaped bracket 9. A traction motor 11 is fixedly installed on one side of the U-shaped bracket 9. The rotation of the traction motor 11... A shaft is fixedly installed at one end of a traction wheel 10. A traction rope 12 is provided on the traction wheel 10. One end of the traction rope 12 is fixedly installed on the outer wall of the traction wheel 10. A U-shaped transmission plate 13 is fixedly installed at the other end of the traction rope 12. An L-shaped stabilizing plate 18 is fixedly installed on the top of the U-shaped transmission plate 13. The L-shaped stabilizing plate 18 and the guide stabilizing rod 3 are slidably installed. A double-acting screw 14 is rotatably installed on the inner walls of both sides of the U-shaped transmission plate 13. A moving block 16 is threaded onto the outer wall of the double-acting screw 14. A guide crossbar 15 is rotatably installed on the inner walls of both sides of the U-shaped transmission plate 13. The guide crossbar 15 and the moving block 16 are connected. 6 is a sliding installation. An L-shaped lifting plate 19 is fixedly installed at the bottom of the moving block 16. A drive motor 17 is fixedly installed on one side of the U-shaped transmission plate 13. The shaft of the drive motor 17 is fixedly installed to one end of the double-acting screw 14. A reinforcing rod 8 is fixedly installed at the bottom of the traction slide plate 4. There are two sets of reinforcing rods 8. The bottom of the two sets of reinforcing rods 8 is fixedly installed to the top of the rammed earth plate 6. An opening is provided inside the frame 1 for the rammed earth plate 6 to move.

The traction motor 11 drives the traction wheel 10 to rotate. The rotation of the traction wheel 10 lifts the U-shaped transmission plate 13 via the traction rope 12. After the U-shaped transmission plate 13 is lifted, the U-shaped connecting plate 7 is raised via the L-shaped lifting plate 19. When the U-shaped connecting plate 7 rises, the rammed earth plate 6 is raised. Then, the drive motor 17 is started, which drives the double-acting screw 14 to rotate. The rotation of the double-acting screw 14 moves the moving block 16, which moves the L-shaped lifting plate 19. After the L-shaped lifting plate 19 moves, the U-shaped connecting plate 7 is released, allowing the rammed earth plate 6 to descend. The rammed earth plate 6 descends and passes through the opening on the frame 1 to perform ramming treatment on the ground.
