Description

Technical Field

[0001] This invention relates to the field of ramming machine technology, specifically to an energy-saving ramming machine for highway construction. Background Technology

[0002] In highway construction projects, the quality of subgrade compaction directly determines the load-bearing capacity and service life of the highway. As the core equipment for subgrade compaction, the operating efficiency and energy consumption of the soil compactor have a crucial impact on construction costs, schedules, and environmental impact. With the continuous expansion of highway construction, especially the increase in rural roads and municipal branch roads, higher demands are placed on the practicality and energy efficiency of soil compactors. Traditional soil compactors are gradually revealing their inability to adapt to current construction needs.

[0003] Most of the rammed earth machines commonly used in current highway construction operate on a "single-point concentrated compaction" model: a mechanical structure drives a hammer to reciprocate vertically, using the impact force of the falling hammer to compact the soil in a designated area of ​​the roadbed. However, this type of rammed earth machine has drawbacks in actual operation. The compaction range of a traditional rammed earth machine is limited to a localized area directly below the hammer, exerting almost no effective force on the surrounding soil. This leaves the surrounding soil in a loose state, requiring multiple adjustments to the rammed earth machine position and repeated compaction operations to achieve uniform compaction of the entire roadbed surface, thus reducing the efficiency of the compaction process.

[0004] Therefore, an energy-saving ramming machine for highway construction is needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] This invention provides an energy-saving ramming machine for highway construction, aiming to solve the problem that the ramming range of the ramming machine is limited to a local area directly below the ramming hammer, and has almost no effective force on the soil layer around the ramming hammer, resulting in low ramming efficiency due to the need for multiple ramming operations.

[0006] An energy-saving earth-raking machine for highway construction according to the present invention includes:

[0007] chassis;

[0008] The rammer is located inside the machine casing and moves up and down along the height of the machine casing.

[0009] Two counterweight structures are arranged on the two opposite sides of the shell, and the counterweight structure comprises a guide slide rail, a lifting slide, a mounting frame, a counterweight tamping assembly, a pressing structure and a pulley assembly. The guide slide rail is mounted on one side of the shell, and the length direction of the guide slide rail is parallel to the height direction of the shell. The lifting slide is slidably connected with the guide slide rail. The mounting frame has at least two, which are mounted on the bottom side of the lifting slide. The counterweight tamping assembly is arranged in the area formed by the mounting frame and the lifting slide. The counterweight tamping assembly is used for tamping the soil on one side of the rammer. The pressing structure is arranged on the lifting slide, and is used for pressing and fixing the counterweight tamping assembly. The pulley assembly is arranged between the lifting slide, the rammer and the shell, and is used for reciprocating the lifting slide up and down with the working of the rammer.

[0010] Preferably, the pulley assembly comprises a fixed pulley, a movable pulley, a connecting rope and a guide wheel. The fixed pulley is mounted on the top of one side of the shell. The movable pulley is connected with the lifting slide. The connecting rope is arranged between the fixed pulley and the movable pulley, and one end of the connecting rope is connected with the top of the movable pulley, and the other end of the connecting rope is connected with the rammer. The guide wheel is mounted on one side of the shell. The connecting rope is rollingly connected with the fixed pulley, the movable pulley and the guide wheel.

[0011] Preferably, the pressing structure comprises an adjusting threaded rod, a mounting plate and a pressing frame. The adjusting threaded rod penetrates through the lifting slide and is threadedly connected with the lifting slide. The mounting plate is rotatably connected with the bottom end of the adjusting threaded rod. The pressing frame has at least two, which are uniformly mounted on the bottom side of the mounting plate.

[0012] Preferably, the counterweight tamping assembly comprises a counterweight seat and a positioning block. The counterweight seat has at least one, and at least two positioning grooves are formed in the bottom side of the counterweight seat. The positioning block has at least two, which are mounted on the top side of the counterweight seat. The number of the positioning blocks corresponds to the number of the positioning grooves. The position of the positioning blocks corresponds to the position of the positioning grooves. The size of the positioning blocks is adapted to the size of the positioning grooves.

[0013] Preferably, the bottom of the guide slide rail is fixedly connected with a limiting and buffering assembly. The limiting and buffering assembly is used for limiting the lifting slide. The limiting and buffering assembly comprises a mounting rod, a limiting block, a clamping nut and a buffering piece. The mounting rod is fixedly connected with the bottom of the guide slide rail. The limiting block is slidably arranged on the mounting rod. The clamping nut has two, which are threadedly connected with the mounting rod. The limiting block is located in the middle of the two clamping nuts. The buffering piece is connected with the limiting block.

[0014] Preferably, the inside of the shell is provided with a driving member, and the output end of the driving member is connected with the rammer.

[0015] Preferably, the two opposite sides of the shell are fixedly mounted with a moving frame, and the bottom of the moving frame has a moving wheel.

[0016] The beneficial effects of this invention are:

[0017] 1. By coordinating the guide rails, lifting slides, mounting frames, counterweight tamping components, and pulley components, the system can perform tamping operations around the tamping hammer while it is tamping the roadbed. This reduces the number of subsequent tamping operations on the roadbed, achieving energy conservation. It also reduces the time required for comprehensive tamping of the road surface during the entire highway construction process, thus improving tamping efficiency.

[0018] 2. The overall weight of the counterweight ramming assembly can be determined by the number of counterweight seats. By selecting different numbers of counterweight seats, the degree of compaction of the soil around the ram can be determined, making the ramming machine more flexible. Through the cooperation of the mounting frame, positioning block, positioning groove and clamping structure, the fixing operation of the counterweight ramming assembly is relatively simple, reducing the time required for installing the counterweight seats and further improving the compaction efficiency.

[0019] 3. The installation rod and clamping nut make the disassembly and assembly of the limit block simple. This not only facilitates the replacement of the limit block, but also allows the lifting slide and its connecting components to be removed when the counterweight ramming assembly is not needed, reducing the overall size of the ramming machine and facilitating subsequent transportation operations.

[0030] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] like Figures 1 to 8 As shown, an energy-saving ramming machine for highway construction according to the present invention includes a housing 10, a ramming hammer 20 is disposed inside the housing 10, and a counterweight structure is disposed on two symmetrical sides of the housing 10. The counterweight structure includes a guide rail 11 installed on one side of the housing 10. The length direction of the guide rail 11 is parallel to the height direction of the housing 10. A lifting slide 30 is slidably disposed on the guide rail 11. At least two U-shaped mounting brackets 31 are fixedly connected to the bottom side of the lifting slide 30. A counterweight ramming assembly is disposed inside the area formed by the mounting brackets 31 and the lifting slide 30. The counterweight ramming assembly is used to ram the soil on one side of the ramming hammer 20. A clamping structure is disposed on the lifting slide 30 to clamp and fix the counterweight ramming assembly. A pulley assembly is disposed between the lifting slide 30, the ramming hammer 20 and the housing 10. The pulley assembly is used to make the lifting slide 30 move up and down reciprocally as the ramming hammer 20 works.

[0032] During the tamping of the roadbed by the tamping hammer 20, the lifting slide 30 moves up and down under the action of the pulley assembly. When the tamping hammer 20 moves downward to tampe the soil, the lifting slide 30 drives the counterweight tamping assembly to move upward under the action of the pulley assembly. After the tamping work is completed, the tamping hammer 20 rises accordingly. At this time, the counterweight tamping assembly will move downward and tampe the area around the tamping hammer 20 by the weight of the counterweight tamping assembly. Thus, while the tamping hammer 20 is tamping the soil, the area around it is also tamped, thereby reducing the number of subsequent tamping operations. This reduces the time required for comprehensive tamping of the road surface during the entire road construction process and improves tamping efficiency.

[0033] like Figures 1-3The pulley assembly includes a fixed pulley 40 installed on one side of the housing 10 and a movable pulley 41 connected to the lifting slide 30. A connecting rope 42 is provided between the fixed pulley 40 and the movable pulley 41. One end of the connecting rope 42 is connected to the top of the movable pulley 41, and the other end of the connecting rope 42 is connected to the tamping hammer 20. A guide wheel 43 is installed on one side inside the housing 10. The connecting rope 42 is tumblingly connected to the fixed pulley 40, the movable pulley 41, and the guide wheel 43.

[0034] A fixed pulley 40 is installed at the top of the housing 10, and is located above the movable pulley 41. A connecting rope 42 passes through the interior of the fixed pulley 40. The fixed pulley 40 changes the direction of the connecting rope 42, causing it to extend downwards. Similarly, the connecting rope 42 passes through the interior of the movable pulley 41, and the movable pulley 41 changes its direction, causing it to extend upwards. This allows the connecting rope 42 to enter the interior of the housing 10 from the top position, guided by a guide. Wheel 43 supports and guides the connecting rope 42, preventing wear on the connecting rope 42. During the descent of the hammer 20, the connecting rope 42 and the fixed pulley 40 cause the movable pulley 41 to drive the lifting slide 30 upward, thereby driving the counterweight ramming assembly upward. The pulley assembly reduces the work required to lift the counterweight ramming assembly, allowing it to rise more smoothly. This significantly reduces the overall workload of the ramming machine while compacting the area around the hammer 20, achieving energy savings.

[0035] It should be noted that a through groove is provided on the housing 10 so that the connecting rope 42 can smoothly enter the interior of the housing 10. Hooks are connected to the top and bottom of the movable pulley 41. One end of the connecting rope 42 is connected to the hook at the top of the movable pulley 41. A lifting ring is connected to the lifting slide 30. The hook at the bottom of the movable pulley 41 is connected to the lifting ring, and the hook has an anti-drop function.

[0036] like Figures 1-5 The clamping structure includes an adjusting threaded rod 32 that is threadedly connected to the lifting slide 30. The bottom end of the adjusting threaded rod 32 is rotatably connected to a mounting plate 33, and at least one clamping bracket 34 is fixedly connected to the bottom side of the mounting plate 33.

[0037] After the counterweight ramming assembly is placed inside the area formed by the mounting frame 31 and the lifting slide 30, the adjusting threaded rod 32 is rotated and moved downward. At this time, the mounting plate 33 drives the clamping frame 34 to move downward, so that the clamping frame 34 fits tightly against the top side of the counterweight ramming assembly, thereby clamping and fixing the counterweight ramming assembly to prevent the counterweight ramming assembly from shifting position.

[0038] It should be noted that a guide rod can be connected to the mounting plate 33, and the guide rod passes through the lifting ring seat 30 and is slidably connected to the lifting slide 30. This can prevent the mounting plate 33 from rotating during movement, so that the clamping frame 34 can more smoothly clamp the counterweight rammed earth component.

[0039] like Figures 1-4 and Figure 6 The counterweight rammed earth assembly includes at least one counterweight base 35. At least two positioning slots 351 are provided on the bottom side of the counterweight base 35. At least two positioning blocks 36 are fixedly connected to the top side of the counterweight base 35. The number of positioning blocks 36 corresponds to the number of positioning slots 351. The positions of positioning blocks 36 and positioning slots 351 correspond to the positions of positioning blocks 36 and positioning slots 351. The size of positioning blocks 36 and positioning slots 351 is adapted to each other. The bottom of the mounting bracket 31 is inserted into the interior of the positioning slots 351.

[0040] When installing the counterweight ramming assembly, first place a counterweight seat 35 into the area formed by the lifting slide 30 and the mounting frame 31, and then insert the mounting frame 31 into the positioning groove 351. At this time, the bottom side of the mounting frame 31 and the bottom side of the counterweight seat 35 are on the same plane. The positioning groove 351 and the mounting frame 31 ensure that the counterweight seat 35 at the bottom will not shift. If multiple counterweight seats 35 are needed during use, the positioning block 36 on one counterweight seat 35 can be inserted into the positioning groove 351 on another counterweight seat 35, and the two counterweight seats 35 can be tightly fitted together. The positioning block 36 and the positioning groove 351 can prevent the counterweight seats 35 from shifting. Then, the machine casing uses a clamping structure to clamp the multiple counterweight seats 35. By selecting different numbers of counterweight seats 35, different degrees of compaction can be achieved on the soil around the ramming hammer 20. The appropriate number of counterweight seats 35 can be selected according to the actual situation of the construction site.

[0041] like Figure 7 and Figure 8 A limiting buffer assembly is fixedly connected to the bottom of the guide slide rail 11. The limiting buffer assembly is used to limit the lifting slide 30 to prevent the lifting slide 30 from separating from the guide slide rail 11. The limiting buffer assembly includes a mounting rod 12 fixedly connected to the bottom of the guide slide rail 11. A limiting block 13 is slidably provided on the outer surface of the mounting rod 12. Two clamping nuts 14 are threadedly connected to the outer surface of the mounting rod 12. The limiting block 13 is located in the middle of the two clamping nuts 14. A buffer element 15 is provided on the limiting block 13.

[0042] During the movement of the lifting slide 30, the buffer 15 and the limiting block 13 limit and buffer the lifting slide 30 to prevent the lifting slide 30 from separating from the guide rail 11. The buffer 15 also buffers the lifting slide 30 when it falls, greatly preventing the lifting slide 30 from vibrating. Furthermore, by separating the clamping nut 14 from the mounting rod 12, the operation of disassembling and assembling the limiting block 13 is relatively simple. This not only facilitates the replacement of the limiting block 13, but also allows the lifting slide 30 and its connecting components to be removed when the counterweight tamping assembly is not needed, reducing the overall size of the tamping machine and making the overall operation more flexible.

[0043] It should be noted that the buffer 15 can be a spring buffer structure or an elastic buffer pad, which can buffer the force generated when the lifting slide 30 descends.

[0044] like Figures 1-3 The housing 10 is equipped with a drive unit 16. The output end of the drive unit 16 is connected to the hammer 20. The drive unit 16 can drive the hammer 20 to reciprocate in the vertical direction, thereby performing the compaction operation.

[0045] It should be noted that a guide assembly (not shown in the figure) is provided between the hammer 20 and the housing 10, which enables the hammer 20 to move smoothly in the vertical direction.

[0046] like Figure 1 and Figure 2 The two symmetrical sides of the casing 10 are fixedly equipped with a movable frame 17. The bottom of the movable frame 17 has movable wheels, which drive the entire ramming machine to move.
