Description

Technical Field

[0001] The utility model relates to the field of frog-type vibrating rammers, in particular to a frog-type vibrating rammer with shock-absorbing function. Background Art

[0002] The frog-type vibrating rammer is a compacting machine that uses impact and vibration to compact backfill soil in layers. It is mainly composed of a rammer, a rammer frame, an eccentric block, a pulley and an electric motor. The motor and the transmission device are installed on the skid, and the rear end of the rammer frame is hinged to the transmission shaft. Under the centrifugal force of the eccentric block, the rammer frame can swing up and down around this shaft. The front part of the rammer frame is equipped with a rammer. When the rammer frame swings downward, the rammer tampers the soil to level and compact the ground.

[0003] The existing technology has the following problems:

[0004] The frog-type vibratory rammer in the prior art has poor shock-absorbing effect. When the frog-type vibratory rammer is used to impact and flatten the ground, due to the lack of a good shock-absorbing structure, the impact force feedback after the frog-type vibratory rammer contacts the ground is too large, which causes serious shock to the entire machine and vibration damage to the workers themselves. Utility Model Content

When the ramming machine is in working state, certain vibrations will be generated. When vibrations are generated, the shock-absorbing mechanism at the bottom of the ramming machine is used in combination with the support rod and the shock-absorbing soft plate to achieve sufficient shock-absorbing effect, so as to reduce the impact of vibrations on equipment and staff, thereby improving the safety of use and meeting people's use needs.

[0008] Preferably, the shock-absorbing mechanism includes a sleeve, the inner wall of the sleeve is movably connected to a movable rod, the bottom end of the movable rod is fixedly connected to a fixed block, and the top of the fixed block is fixedly installed with a return spring.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] The preferred embodiment of the shock-absorbing frog-type vibration rammer provided by the utility model is as follows: Figures 1 to 3 As shown: a shock-absorbing frog-type vibration rammer, comprising a base plate 1, a handle 2 is fixedly connected to the top of the base plate 1, a motor 3 is fixedly installed on the top of the base plate 1, the output shaft of the motor 3 is fixedly connected to the rotating shaft 4 through a coupling, the outer wall of the rotating shaft 4 is movably connected to a transmission belt 5, the inner wall of the transmission belt 5 is movably connected to a transmission wheel 6, the inner wall of the transmission wheel 6 is fixedly connected to a movable shaft 7, the outer wall of the movable shaft 7 is movably connected to a support block 8, the front of the support block 8 is movably connected to a rammer frame 10, and the bottom of the rammer frame 10 is fixedly connected to a rammer hammer 11.

[0023] A rotating rod 12 is movably connected to one side of the ramming frame 10, a driven wheel 14 is fixedly connected to the outer wall of the rotating rod 12, a driven belt 13 is movably connected to the outer wall of the driven wheel 14, an eccentric block 15 is fixedly connected to the outer wall of the rotating rod 12, a shock-absorbing mechanism 16 is fixedly installed at the bottom of the base plate 1, a roller 17 is fixedly installed at the bottom of the shock-absorbing mechanism 16, and a support rod 18 is fixedly connected to one side of the shock-absorbing mechanism 16, so that the ramming machine has a good shock-absorbing effect. When the ramming machine is in working state, a certain vibration will be generated. When the vibration is generated, the shock-absorbing mechanism 16 at the bottom of the ramming machine is used in conjunction with the support rod 18 and the shock-absorbing soft plate 19 to achieve sufficient shock-absorbing effect, thereby reducing the impact of the vibration on the equipment and staff, thereby improving the safety of use and meeting people's use needs.

[0024] In this embodiment, the shock-absorbing mechanism 16 includes a sleeve 1601, the inner wall of the sleeve 1601 is movably connected to a movable rod 1602, the bottom end of the movable rod 1602 is fixedly connected to a fixed block 1604, and the top of the fixed block 1604 is fixedly installed with a return spring 1603. The shock-absorbing mechanism 16 utilizes the return spring 1603 in cooperation with the movable rod 1602 to reduce the vibration generated by the operation of the equipment, thereby avoiding negative effects caused by excessive vibration.

[0025] In this embodiment, a movable groove is provided on the inner wall of the sleeve 1601, and the sleeve 1601 is movably connected to the movable rod 1602 through the movable groove. The movable groove enables the movable rod 1602 to be more convenient to rise and fall on the inner wall of the sleeve 1601, thereby cooperating with the reset spring 1603 to play a role.

[0026] In this embodiment, a shock-absorbing soft plate 19 is fixedly connected to the bottom of the base plate 1. The shock-absorbing soft plate 19 can abut against the support rod 18, thereby using the flexibility of the shock-absorbing soft plate 19 to give the support rod 18 an opposite force, thereby cooperating with the shock-absorbing mechanism 16 to provide a shock-absorbing effect.

[0027] In this embodiment, there are two shock-absorbing soft plates 19 , and the two shock-absorbing soft plates 19 are symmetrically arranged with the vertical midline of the bottom plate 1 as the symmetry axis. The two shock-absorbing soft plates 19 can provide a more sufficient shock-absorbing effect.

[0028] Example 2

[0029] On the basis of Example 1, the preferred embodiment of the shock-absorbing frog-type vibration rammer provided by the utility model is as follows: Figures 1 to 3 As shown: the front side of the support block 8 is fixedly connected with a bearing 9, and the support block 8 is movably connected to the tamping frame 10 through the bearing 9. The bearing 9 can provide a rotation support force for the tamping frame 10 and can prevent the tamping frame 10 from being forced to rotate and getting stuck.

[0030] When in use, the motor 3 drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the transmission belt 5 on its outer wall to move. The transmission belt 5 drives the transmission wheel 6 to rotate, and the transmission wheel 6 rotates and drives the driven belt 13 to move, and the driven belt 13 drives the driven wheel 14 to rotate, and the driven wheel 14 drives the rotating rod 12 and the eccentric block 15 to rotate, and the centrifugal force under the movement of the eccentric block 15 is used to drive the rammer frame 10 to move up and down, so that the rammer frame 10 drives the rammer 11 to repeatedly hit the soil. The vibration after hitting the soil will be transmitted to the bottom plate 1. At this time, the bottom plate 1 floats up and down due to the vibration, and thereby the sleeve 1601 floats up and down on the outer wall of the movable rod 1602. At this time, the reset spring 1603 is used to reset and support the sleeve 1601 to offset a certain vibration, and when the bottom plate 1 floats up and down, it will drive the shock-absorbing soft plate 19 to abut against the support rod 18, so that the shock-absorbing soft plate 19 provides a further shock-absorbing effect.

[0031] To sum up, the frog-type vibration rammer with shock absorption can achieve the purpose of good shock absorption effect. When the rammer is in working state, it will generate certain vibration. When the vibration occurs, the shock absorption mechanism 16 at the bottom of the rammer is used in conjunction with the support rod 18 and the shock absorption soft plate 19 to achieve sufficient shock absorption effect, thereby reducing the impact of the vibration on the equipment and staff, thereby improving the safety of use and meeting people's use needs.
