[0002] A tamping machine is a type of mechanical equipment widely used in earthwork projects. Its main function is to compact the soil through impact and vibration to increase the soil's density and bearing capacity, thereby making the soil more stable. When tamping the soil in an area, it is necessary to move the machine back and forth in a straight line. However, due to the high-speed vibration of the tamping machine, the operator's hand force can cause the tamping machine to move offset, preventing the tamping motion from running in a straight line. The general solution is to use a manual rope to drag the tamping board to help correct the linear motion trajectory, which increases labor intensity. Utility Model Content

[0026] See also Figure 1-5 The utility model provides a technical solution for a rammer for civil construction.

[0027] like Figure 1 As shown, it includes a ramming machine body 1, a ramming plate 7 is installed at the bottom of the ramming machine body 1, and the ramming plate 7 is a part of the ramming machine body 1. When the ramming machine body 1 is working, the ramming plate 7 vibrates up and down and contacts the ground to ram the soil. The upper surface of the ramming plate 7 is installed with a linear limit component 3 through the mounting component 2, wherein the mounting component 2 is used to connect the linear limit component 3 and the ramming plate 7. The linear limit component 3 is slidably connected to the mounting component 2 through the sliding component 4. The sliding component 4 includes a rotating wheel 43, and the mounting component 2 includes a sliding rail 22. The rotating wheel 43 can slide inside the sliding rail 22, and the sliding component 4 enables the mounting component 2 to be movably connected with the linear limit component 3, so as to prevent the linear limit component 3 from vibrating up and down when the ramming plate 7 vibrates. The linear limit component 3 includes a linear limit plate 32, and the linear limit plate 32 is inserted into the ground surface. After the linear limit plate 32 is inserted into the ground surface, it pushes the ramming machine body 1 to move. The linear limit plate 32 moves on the soil surface. If the ramming machine body 1 is not controlled to turn, it will move along a straight line. The limit component 3 is used to limit the linear trajectory of the movement of the ramming plate 7.

[0028] like Figure 1As shown, the linear limit plate 32 in the limit assembly 3 is unfolded and inserted into the soil on the surface. The linear limit plate 32 is initially plugged in after contacting the soil surface. When the rammer body 1 drives the ramming plate 7 to vibrate up and down at high frequency, it drives the installation assembly 2 to vibrate up and down. When tamping an area, it is necessary to push the rammer body 1 to move for tamping. The rammer body 1 can be moved by slightly applying a forward pushing force. The linear limit plate 32 moves accordingly in the soil. The plugging of the linear limit plate 32 in the soil also limits the moving route of the rammer body 1. The plugging of the linear limit plate 32 is not affected by external forces and will not change direction. The rammer body 1 moves according to the limit of the linear limit plate 32 to avoid deviation of the moving route due to vibration, and replaces manual dragging to correct the route.

[0029] For example, when tamping an area, the linear limit plate 32 is inserted into the surface of the soil. When the ramming machine body 1 is tamping, it drives the ramming plate 7 to vibrate at high frequency. The ramming machine body 1 needs to move to perform tamping work. The ramming plate 7 drives the mounting assembly 2 to move up and down. When the ramming machine body 1 moves, the linear limit assembly 3 is pushed forward through the mounting assembly 2. When the linear limit plate 32 moves, the mounting assembly 2 can slide longitudinally on the linear limit assembly 3, that is, the linear limit assembly 3 is not affected by the vibration of the ramming machine body 1. The ramming machine body 1 can only move in a straight line along the limit of the linear limit plate 32 inserted in the soil.

[0030] like Figure 1 As shown, the linear limit assembly 3 includes a turning rod 31, and sliding assemblies 4 are installed on both sides of one end of the turning rod 31. The other end of the turning rod 31 is movably installed with a linear limit plate 32 through a rotating shaft 34. A slot 33 is opened inside the linear limit plate 32, and the linear limit plate 32 is fixed in the expanded state by a locking assembly 5.

[0031] like Figure 2 As shown, the turning rod 31 is a medium connected to the mounting assembly 2 and is also used to install the linear limit plate 32. The slot 33 is stuck on the outer wall of the turning rod 31 when the linear limit plate 32 is retracted to achieve the retraction of the linear limit plate 32. Figure 5 The middle straight line limit plate 32 utilizes the clamping state between the slot 33 and the turning rod 31, as shown in FIG. Figure 3 As shown, the rotating shaft 34 makes the connection between the turning rod 31 and the limiting plate 32 foldable, so that the linear limiting plate 32 can be installed on the rammer body 1.

[0032] When the linear limit plate 32 is used to rotate on the turning rod 31 with the rotating shaft 34 as the rotation point, it is inserted into the soil surface in a straight state. This state is fixed by the locking component 5. When retracting, the linear limit plate 32 is folded and the slot 33 is stuck in the outer wall of the turning rod 31 to complete the retraction.

[0033] like Figure 2 As shown, the sliding assembly 4 includes a wheel frame 41 , which is mounted on the crank 31 , and a rotating wheel 43 is movably mounted inside the wheel frame 41 via a connecting shaft 42 .

[0034] The sliding assembly 4 makes the linear limit assembly 3 and the mounting assembly 2 slidingly connected. The wheel frame 41 is installed on the crank 31 and is used to install the rotating wheel 43. The rotating wheel 43 rotates on the wheel frame 41, so that when the top of the crank 31 is subjected to external force, the top of the crank 31 can be movable due to the rotatability of the rotating wheel 43.

[0035] like Figure 2 As shown, the mounting assembly 2 includes a mounting frame 21 , and sliding rails 22 are installed on both sides of the inner wall of the mounting frame 21 , and the rotating wheel 43 rolls inside the sliding rails 22 .

[0036] Combined with the above-mentioned sliding assembly 4, when the mounting assembly 2 vibrates on the rammed earth plate 7, the sliding rail 22 can move up and down accordingly. The sliding rail 22 moves up and down on the outer wall of the rotating wheel 43. The rotating wheel 43 rotates after being subjected to force. When the mounting frame 21 is pushed along with the rammed earth plate 7, the mounting frame 21 applies a driving force to the rotating wheel 43, pushing the entire linear limit assembly 3 to move.

[0037] like Figure 3 As shown, the locking assembly 5 includes a support rod 51 and a cartridge 55. The cartridge 55 is mounted on the outer wall of the rotating shaft 34. The support rod 51 is mounted on the crank rod 31. A rotating tube 52 is mounted on the outer wall of the support rod 51. One end of a push rod 53 is mounted on the outer wall of the rotating tube 52. The other end of the push rod 53 is integrally formed with a clamping rod 54, which is clamped into the interior of the cartridge 55.

[0038] exist Figure 3 It can be understood that after the linear limit plate 32 is extended, the push rod 53 drives the rotating tube 52 to rotate on the outer wall of the support rod 51, drives the clamping rod 54 to be clamped into the inside of the clamping cylinder 55, limits the rotating shaft 34, and prevents the rotating shaft 34 from rotating, so that the extended state of the linear limit plate 32 is fixed, thereby fixing the state of the linear limit plate 32 inserted into the ground. When folding is required, the push rod 53 is rotated to disengage the clamping rod 54 from the clamping cylinder 55, stop limiting the rotating shaft 34, and the linear limit plate 32 can move to fold and retract.

[0039] like Figure 4 As shown, in order to increase the tightness of the linear limit plate 32 inserted into the soil, a counterweight assembly 8 is installed at the end of the linear limit plate 32. The counterweight assembly 8 increases the downward pressure of the linear limit assembly 32. The counterweight assembly 8 includes a sleeve 81 and a screw barrel 83. The screw barrel 83 is installed inside the slot 33. A screw rod 84 is installed at the bottom of the sleeve 81. The screw rod 84 is threadedly connected to the screw barrel 83. The outer wall of the sleeve 81 is sleeved with a counterweight plate 82.

[0040] The screw 84 can be installed inside the screw barrel 83 so that the sleeve 81 is installed on the linear limit plate 32, and the outer wall of the sleeve 81 is connected to the counterweight plate 82. The weight of the counterweight plate 82 can press down the linear limit plate 32 to tightly insert it into the soil. Under the threaded installation of the screw 84 and the screw barrel 83, the counterweight assembly 8 can be installed and disassembled on the linear limit assembly 32.

[0041] To prevent the sliding assembly 4 from escaping from the interior of the mounting plate 21 , a baffle 6 is detachably mounted on the top of the sliding rail 22 , and the baffle 6 seals the top of the mounting plate 21 .

[0042] In order to allow the linear limiting plate 32 to be smoothly inserted into the soil, the linear limiting plate 32 is thick at the top and thin at the bottom. This shape has a higher bottom pressure and can be easily inserted into the soil.

[0043] In order to extend the service life of the rotating wheel 43 , the rotating wheel 43 is made of nitrile rubber, which has good wear resistance.

[0044] In order to increase the ability of the linear limiting plate 32 to move forward, a soil-breaking cone 9 is installed at the end of the linear limiting plate 32. The sharp state of the soil-breaking cone 9 can break through the soil when moving.

[0045] The working principle of the present invention is explained below with an advantageous embodiment: after the linear limit plate 32 is pulled, it is rotated and extended with the rotating shaft 34 as the rotating point, and the linear limit plate 32 is stuck in the soil surface, and the screw 84 is threaded inside the screw barrel 83 so that the sleeve 81 is installed on the linear limit plate 32, and the outer wall of the sleeve 81 is sleeved on the counterweight plate 82. The weight of the counterweight plate 82 can press down the linear limit plate 32 and insert it into the soil to prevent the linear limit plate 32 from separating from the soil. After the rammer body 1 is working, it drives the ramming plate 7 to vibrate and perform ramming work. When the mounting assembly 2 vibrates on the ramming plate 7, the sliding rail 22 can move up and down accordingly. The sliding rail 22 moves up and down on the outer wall of the rotating wheel 43, and the rotating wheel 43 rotates after being force-bearing. When the mounting frame 21 is pushed by the ramming plate 7, the mounting frame 21 applies a driving force to the rotating wheel 43, pushing the entire linear limit assembly 3 to move. Under the trajectory limit of the linear limit plate 32, the rammer body 1 performs linear motion.
