Description

Technical Field

[0001] This invention relates to the field of construction equipment technology, and in particular to a rammer for civil engineering. Background Technology

[0002] A rammer is a machine used to compact road surfaces, primarily for leveling and compacting foundations during construction. There are two types of rammers: road compactors and road breakers. Road breakers have seen significant market demand in recent years. They are compaction machines that use impact and vibration to compact backfill soil in layers. They can also be used to break up road surfaces in layers for ditching and the repair and maintenance of old road surfaces. Rammers are also needed in civil engineering construction. Commonly used rammers include high-speed rammers and electric frog-type rammers. When using a rammer, workers need to manually operate it, as the frequent vibrations are transmitted to the workers, making operation quite cumbersome. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the prior art by proposing a rammer for building construction.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a tamping machine for building construction, including a support frame, tamping mechanisms are provided on the front and rear sides of the support frame, rollers are rotatably connected to the left and right sides of the rear part of the support frame, and rollers are connected to the left and right sides of the front part of the support frame through a toggle mechanism, and the rear side of the toggle mechanism is magnetically attracted to the rear tamping mechanism.

[0005] Preferably, the actuating mechanism includes a lever, a shaft, a ratchet, and a second pawl. The left and right sides of the lever are rotatably connected to the left and right sides of the support frame via torsion springs. One end of the shaft passes through the lever and is rotatably connected to the left and right sides of the support frame. The other end of the shaft is fixedly connected to the middle of the roller. The middle of the ratchet is fixedly connected to the outer periphery of the shaft. One end of the second pawl is rotatably connected to the outside of the lever via a torsion spring. The other end of the second pawl engages with the ratchet.

[0006] Preferably, the support frame has pawls mounted on its left and right sides via torsion springs, and the other end of each pawl engages with a ratchet.

[0007] Preferably, the tamping mechanism includes a housing, a gripping mechanism, and a tamping mechanism. The gripping mechanism is installed on the upper part of the housing, the tamping mechanism is installed on the lower part of the housing, and the outer periphery of the housing is fixedly connected to the front and rear sides of the support frame.

[0008] Preferably, the gripping mechanism includes a servo motor, a threaded rod, a slip ring, a connecting rod, a limiting shell, a support plate, grippers, and a guide groove. The lower part of the limiting shell is fixedly connected to the upper part of the outer shell. The upper end of the threaded rod is rotatably connected to the upper part of the limiting shell. The servo motor is mounted on the upper part of the limiting shell. The lower drive end of the servo motor passes through the limiting shell and is fixedly connected to the upper end of the threaded rod. The middle part of the slip ring is threadedly connected to the outer periphery of the threaded rod. The outer periphery of the slip ring is slidably connected to the inside of the limiting shell. The upper end of the connecting rod is fixedly connected to the lower part of the slip ring. The lower end of the connecting rod is fixedly connected to the upper part of the support plate. The middle part of the gripper is rotatably connected to the outer periphery of the support plate via a torsion spring. The guide groove is formed in the upper part of the outer shell.

[0009] Preferably, the tamping mechanism includes a spring, a tamping block, and a connector. The lower part of the connector is fixedly connected to the upper part of the tamping block, the outer periphery of the connector is disposed on the lower part of the gripper, and the spring is disposed on the upper part of the tamping block.

[0010] Preferably, a permanent magnet is provided inside the tamping block, and the lever is made of a magnetic material, with the permanent magnet attracting the lever.

[0011] Preferably, one end of the support frame is provided with a handle.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The tamping mechanism drives the rear of the lever to press down, and then the torsion spring causes the rear of the lever to lift up. This cycle repeats, causing the rear of the lever to move up and down repeatedly. This causes the ratchet to rotate through the second pawl, which in turn drives the roller to rotate through the shaft. Thus, the lever moves while tamping the soil, requiring no human assistance. The operation is very simple. Attached Figure Description

[0022] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0023] like Figures 1-7 The illustrated tamping machine for building construction includes a support frame 2. Tamping mechanisms 1 are arranged on the front and rear sides of the support frame 2. Rollers 4 are rotatably connected to the left and right sides of the rear part of the support frame 2. The rollers 4 are connected to the left and right sides of the front part of the support frame 2 via a toggle mechanism 3. The rear side of the toggle mechanism 3 is magnetically attracted to the rear tamping mechanism 1. In summary, the servo motor 1021 drives the threaded rod 1022 to rotate. Since the slip ring 1023 is restricted from rotating by the limiting shell 1025, the threaded rod 1022 drives the slip ring 1023 to move up and down. This, in turn, drives the support plate 1026 and the gripper 1027 to move up and down via the limiting shell 1025. When the gripper 1027 moves into the guide groove 1028, the upper part of the gripper 1027 gradually contracts, causing the lower part of the gripper 1027 to open, thus allowing the connecting head 1 to... Released from the ground, the tamping block 1032 impacts the soil under the influence of gravity and spring 1031. When the gripper 1027 moves downward, it re-grabs the tamping block 1032 and moves upward, repeating the tamping process. Through the attraction between the permanent magnet and the lever 301, the lever 301 moves downward when the tamping block 1032 falls. When the tamping block 1032 impacts the ground, the permanent magnet can no longer attract the lever 301, and the lever 301 resets under the action of the torsion spring. This cycle repeats, causing the rear end of the lever 301 to move up and down repeatedly. This causes the ratchet 303 to rotate via the second pawl 305, which in turn drives the roller 4 to rotate via the shaft 302. Thus, the tamping of the soil is performed while the movement is complete, requiring no human assistance and making the operation very simple.

[0024] The actuating mechanism 3 includes a lever 301, a shaft 302, a ratchet 303, and a second pawl 305. The left and right sides of the lever 301 are rotatably connected to the left and right sides of the support frame 2 via torsion springs. One end of the shaft 302 passes through the lever 301 and is rotatably connected to the left and right sides of the support frame 2. The other end of the shaft 302 is fixedly connected to the middle of the roller 4. The middle of the ratchet 303 is fixedly connected to the outer periphery of the shaft 302. One end of the second pawl 305 is rotatably connected to the outside of the lever 301 via a torsion spring. The other end of the second pawl 305 meshes with the ratchet 303. The tamping mechanism 1 drives the rear side of the lever 301 to press down, and then the torsion spring causes the rear side of the lever 301 to lift up. This cycle repeats, causing the rear side of the lever 301 to move up and down, thereby driving the ratchet 303 to rotate via the second pawl 305, which in turn drives the roller 4 to rotate via the shaft 302. Thus, the lever 301 moves while tamping the soil, requiring no human assistance and making operation very simple.

[0025] Pads 304 are installed on the left and right sides of the support frame 2 via torsion springs. The other end of the pawl 304 engages with the ratchet 303. The engagement of the pawl 304 with the ratchet 303 prevents the ratchet 303 from rotating in the opposite direction when the lever 301 is lifted, thereby preventing the support frame 2 from moving backward on a slope.

[0026] The tamping mechanism 1 includes a housing 101, a gripping mechanism 102, and a tamping mechanism 103. The gripping mechanism 102 is installed on the upper part of the housing 101, and the tamping mechanism 103 is installed on the lower part of the housing 101. The outer periphery of the housing 101 is fixedly connected to the front and rear sides of the support frame 2. In summary, the threaded rod 1022 is driven to rotate by the servo motor 1021. Since the slip ring 1023 is restricted from rotating by the limiting shell 1025, the threaded rod 1022 drives the slip ring 1023 to move up and down, thereby achieving the limiting effect. The shell 1025 drives the support plate 1026 and the gripper 1027 to move up and down. When the gripper 1027 moves into the guide groove 1028, the upper part of the gripper 1027 gradually contracts, causing the lower part of the gripper 1027 to open, thereby releasing the connector 1033. Under the action of gravity and spring 1031, the tamping block 1032 tamps the soil. When the gripper 1027 moves downward, it will grab the tamping block 1032 again and move upward, repeating the tamping process.

[0027] The gripping mechanism 102 includes a servo motor 1021, a threaded rod 1022, a slip ring 1023, a connecting rod 1024, a limiting shell 1025, a support plate 1026, grippers 1027, and a guide groove 1028. The lower part of the limiting shell 1025 is fixedly connected to the upper part of the outer shell 101. The upper end of the threaded rod 1022 is rotatably connected to the upper part of the limiting shell 1025. The servo motor 1021 is mounted on the upper part of the limiting shell 1025. The lower drive end of the servo motor 1021 passes through the limiting shell 1025 and is fixedly connected to the upper end of the threaded rod 1022. The middle part of the slip ring 1023 is threadedly connected to the outer circumference of the threaded rod 1022, and the outer circumference of the slip ring 1023 is slidably connected to the inside of the limiting shell 1025. The upper end of the connecting rod 1024 is fixedly connected to the lower part of the slip ring 1023, and the lower end of the connecting rod 1024 is fixedly connected to the upper part of the support plate 1026. Grippers 1027... The middle part is rotatably connected to the outer periphery of the support plate 1026 via a torsion spring. The guide groove 1028 is opened on the upper part of the outer shell 101. The threaded rod 1022 is driven to rotate by the servo motor 1021. Since the slip ring 1023 is restricted by the limiting shell 1025 and cannot rotate, the threaded rod 1022 drives the slip ring 1023 to move up and down. In turn, the limiting shell 1025 drives the support plate 1026 and the gripper 1027 to move up and down. When the gripper 1027 moves into the guide groove 1028, the upper part of the gripper 1027 gradually contracts, causing the lower part of the gripper 1027 to open, thereby releasing the connector 1033. Under the action of gravity and the spring 1031, the tamping block 1032 tamps the soil. When the gripper 1027 moves downward, the gripper 1027 will grab the tamping block 1032 again and move upward, repeating the tamping process.

[0028] The tamping mechanism 103 includes a spring 1031, a tamping block 1032, and a connector 1033. The lower part of the connector 1033 is fixedly connected to the upper part of the tamping block 1032. The outer periphery of the connector 1033 is disposed on the lower part of the gripper 1027. The spring 1031 is disposed on the upper part of the tamping block 1032. When the connector 1033 is released, the tamping block 1032 tamps the soil under the action of gravity and the spring 1031.

[0029] The tamping block 1032 has a permanent magnet inside, and the lever 301 is made of a magnetic material. The permanent magnet attracts the lever 301. Through the attraction between the permanent magnet and the lever 301, the rear of the lever 301 moves downward when the tamping block 1032 falls. When the tamping block 1032 hits the ground, the permanent magnet can no longer attract the lever 301. Under the action of the torsion spring, the lever 301 returns to its original position. This cycle repeats, causing the rear end of the lever 301 to move up and down repeatedly.

[0030] The support frame 2 is equipped with a handle at one end for easy pushing and pulling and easy movement.

[0031] Working principle:

[0032] The servo motor 1021 drives the threaded rod 1022 to rotate. Since the slip ring 1023 is restricted from rotating by the limiting shell 1025, the threaded rod 1022 causes the slip ring 1023 to move up and down. This, in turn, causes the support plate 1026 and the gripper 1027 to move up and down via the limiting shell 1025. When the gripper 1027 moves into the guide groove 1028, the upper part of the gripper 1027 gradually contracts, causing the lower part of the gripper 1027 to open, thus releasing the connector 1033. Under the action of gravity and the spring 1031, the tamping block 1032 tamps the soil. When the gripper 1027 moves downwards, the gripper... 1027 will re-grab the tamping block 1032 and move it upwards, repeating the tamping process. Through the attraction between the permanent magnet and the lever 301, when the tamping block 1032 falls, the rear of the lever 301 moves downwards. When the tamping block 1032 hits the ground, the permanent magnet can no longer attract the lever 301, and under the action of the torsion spring, the lever 301 returns to its original position. This cycle repeats, causing the rear end of the lever 301 to move up and down repeatedly. This causes the ratchet 303 to rotate through the pawl 305, which in turn drives the roller 4 to rotate through the shaft 302. Thus, the lever moves while tamping the soil, requiring no human assistance, making the operation very simple.
