Abstract
Description
Technical Field
[0001] This utility model relates to the field of impact rammer handle technology, specifically to an impact rammer with a shock-absorbing handle. Background Technology
[0002] A compaction rammer is a compaction machine that uses impact and vibration to compact backfill soil in layers. It includes electric impact rammers, gasoline impact rammers, and vibratory impact rammers, etc., all made using the principle of rotational inertia. It consists of a hammer, frame, eccentric block, pulley, and electric motor. Both impact rammers and plate rammers require operators to hold the handles and control the rammer's movement. Plate rammers are used to compact materials with low interparticle cohesion and friction. They are divided into internal combustion and electric vibratory plate rammers. The plate rammer model number consists of two parts: category, group, type, and characteristic code and main parameter code. The update code for the plate rammer is placed at the end of the model number.
[0003] Currently, impact rammers continuously compact the ground through the reciprocating vibration of the plate. When workers hold the handles of impact rammers or plate rammers for extended periods, the vibration affects their bodies, causing joint wear and tear, indirectly increasing the intensity of operation, and potentially causing irreversible damage. The resulting arm soreness and numbness also affect the efficiency of impact rammer operation. Therefore, it is necessary to design an impact rammer with shock-absorbing handles to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide an impact rammer with a shock-absorbing handle to address the aforementioned shortcomings in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An impact rammer with a shock-absorbing handle includes:
[0007] The mounting frame has two fixing blocks fixedly connected to one side, and each of the two fixing blocks has a connecting rod fixedly connected to one side.
[0008] The mounting block is fixedly connected to one side of the connecting rod. The top surface of the mounting block and the top surface of the fixing block are both provided with sliding grooves. The top surfaces of the two fixing blocks and the top surfaces of the two mounting blocks are provided with connecting handles, which are movably fitted together with the sliding grooves.
[0009] A buffer spring is fixedly connected to the bottom surface inside the sliding groove. A damping rod is fixedly connected to the bottom surface inside the sliding groove. The top end of the telescopic shaft of the damping rod is fixedly connected to the bottom end of the connecting handle.
[0010] A limiting component is disposed inside the sliding groove to limit the connection handle.
[0011] Preferably, the limiting component includes:
[0012] A plurality of limiting grooves are formed at equal angles on the inner circular wall of the sliding groove, and a limiting block is fixedly connected at equal angles to the outer circular wall of the connecting handle, and the limiting block is movably sleeved with the limiting groove.
[0013] Preferably, the outer circular wall of the connecting handle is fixedly connected to two handles, and the outer circular wall of the handle is fixedly connected to a buffer tube.
[0014] Preferably, the mounting frame has ramming body support plates fixedly connected to both the left and right sides inside, and two mounting holes are opened on one side of the ramming body support plate.
[0015] Preferably, reinforcing ribs are fixedly connected between the two fixing blocks and between the two mounting blocks, and protective sleeves are provided on the outside of the reinforcing ribs.
[0016] Preferably, a handle is fixedly connected between the two mounting blocks, a buffer pad is fixedly connected to the outside of the handle, and an impact rammer body is provided inside the mounting frame.
[0017] In the above technical solution, the impact rammer with shock-absorbing handle provided by this utility model has the following beneficial effects:
[0018] By setting up an installation frame, when the worker fixes the impact rammer body inside the installation frame, the impact force generated by the impact rammer body during operation can be transmitted to the installation frame. Since the outer wall of the handle is equipped with a buffer pad, the vibration transmitted from the installation frame to the worker can be reduced when the worker holds the handle, thereby reducing joint wear and tear on various joints of the body, indirectly reducing the intensity of operation, and thus improving the worker's work efficiency.
[0019] When workers are actually working, by gripping the connecting handle or grip, the vibration of the mounting frame needs to be transmitted to the connecting handle through the buffer spring and damping rod. At this time, the buffer spring and damping rod work together to reduce the transmission of vibration of the mounting frame. This further reduces the vibration generated by the impact rammer body from being transmitted to the worker when the worker is working by gripping the connecting handle or grip on the side of the mounting frame. This reduces joint wear and tear on various joints of the body, indirectly reduces the intensity of operation, and improves the worker's work efficiency. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0027] like Figure 1-4 As shown in the figure, the impact rammer with shock-absorbing handle provided by this utility model embodiment includes a mounting frame 1, two fixing blocks 2 are fixedly connected to one side of the mounting frame 1, and a connecting rod 3 is fixedly connected to one side of each of the two fixing blocks 2.
[0028] A mounting block 4 is fixedly connected to one side of the connecting rod 3. Sliding grooves 5 are provided on the top surface of both the mounting block 4 and the top surface of both fixing blocks 2. Connecting handles 6 are provided on the top surfaces of both fixing blocks 2 and both mounting blocks 4, and are movably fitted together with the sliding grooves 5. A buffer spring 7 is fixedly connected to the bottom surface inside the sliding groove 5, and a damping rod 8 is fixedly connected to the bottom surface inside the sliding groove 5. The top end of the telescopic shaft of the damping rod 8 is fixedly connected to the bottom end of the connecting handle 6. A limiting component is provided inside the sliding groove 5 to limit the movement of the connecting handle 6.
[0029] In this embodiment, by setting a limiting component, the limiting component can limit the connection handle 6.
[0030] Specifically, the limiting component includes several limiting grooves 9, which are evenly spaced on the inner circular wall of the sliding groove 5. The outer circular wall of the connecting block 6 is evenly fixedly connected to the limiting block 10, which is movably fitted together with the limiting groove 9.
[0031] In this embodiment, by setting a limiting block 10, when the limiting block 10 is movably sleeved with the limiting groove 9, the limiting block 10 can limit the connecting handle 6, thereby preventing the connecting handle 6 from moving out of the sliding groove 5.
[0032] Specifically, two handles 11 are fixedly connected to the outer circular wall of the connector 6, and a buffer tube 12 is fixedly connected to the outer circular wall of the handle 11.
[0033] In this embodiment, by setting a buffer tube 12, when the worker holds the two handles 11 on the side of the mounting frame 1, the buffer tube 12 can improve the worker's grip comfort.
[0034] Specifically, the left and right sides of the interior of the mounting frame 1 are fixedly connected with ramming body support plates 13, and two mounting holes 14 are opened on one side of the ramming body support plate 13.
[0035] In this embodiment, since two mounting holes 14 are provided on one side of the ramming body support plate 13, it is convenient to use bolts to fix the ramming body support plate 13 in a suitable position later.
[0036] Specifically, reinforcing ribs 15 are fixedly connected between the two fixing blocks 2 and between the two mounting blocks 4, and protective sleeves 16 are provided on the outside of the reinforcing ribs 15.
[0037] In this embodiment, by providing reinforcing ribs 15, the stability between the two mounting blocks 4 can be increased.
[0038] Specifically, a handle 17 is fixedly connected between the two mounting blocks 4, a buffer pad 18 is fixedly connected to the outside of the handle 17, and an impact rammer body 19 is set inside the mounting frame 1.
[0039] In this embodiment, since the outer wall of the handle 17 is provided with a buffer pad 18, when the worker holds the handle 17, the vibration transmitted from the mounting frame 1 to the worker can be reduced, thereby reducing joint wear on various joints of the body, indirectly reducing the intensity of operation, and thus improving the worker's work efficiency.
[0040] Working steps: 1. By setting up the mounting frame 1, when the worker fixes the impact rammer body 19 inside the mounting frame 1, the impact force generated by the impact rammer body 19 when it is working can be transmitted to the mounting frame 1. Since the outer wall of the handle 17 is provided with a buffer pad 18, the vibration transmitted from the mounting frame 1 to the worker can be reduced when the worker holds the handle 17, thereby reducing joint wear on various joints of the body, indirectly reducing the intensity of operation, and thus improving the worker's work efficiency.
[0041] Second, when workers are actually working, by holding the connecting handle 6 or the handle 11, the vibration on the mounting frame 1 needs to be transmitted to the connecting handle 6 through the buffer spring 7 and the damping rod 8. At this time, the buffer spring 7 and the damping rod 8 work together to reduce the transmission of vibration of the mounting frame 1. This allows the vibration generated by the impact ram body 19 to be further reduced when workers hold the connecting handle 6 or the handle 11 on the side of the mounting frame 1. This reduces joint wear on various joints of the body, indirectly reduces the intensity of operation, and improves the work efficiency of workers.
[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
