Description

Technical Field

[0001] The invention relates to the technical field of building construction equipment, and in particular to a magnetic induction tamping device. Background Art

[0002] During the land infrastructure construction and maintenance process, it is usually necessary to compact the sand and gravel of the roadbed. A rammer is a road compaction machine that uses impact and vibration to compact backfill soil in layers. It is mostly used to level and compact the foundation during construction. It can also be used to break up the road surface during trenching and renovation and maintenance of old roads.

[0003] Among the existing rammers, the frog-type rammer is driven by an electric motor to rotate the eccentric block. Under the action of centrifugal force, the hammer head below works in a frog-leaping manner, thereby quickly tamping the ground. However, this type of rammer has low working efficiency and poor structural stability. It will generate vibration and noise during use and is very prone to dust, making it difficult to meet the compaction requirements of different roadbed projects. Summary of the invention

The execution coil 5 will generate induced eddy currents in the pulse magnetic field and form a magnetic field. The magnetic field generated by the execution coil 5 and the magnetic field generated by the return coil 4 repel each other to form a pulse electromagnetic force. The pulse electromagnetic force drives the execution coil 5 to drive the impact rod 1 to move upward, and the upward moving impact rod 1 compresses the first buffer component 2; further, the circuit of the return coil 4 is disconnected, and the circuit of the stroke coil 3 is closed at the same time. Similarly, a repulsive force is generated between the stroke coil 3 and the execution coil 5, so that the execution coil 5 drives the impact rod 1 to move downward, and the first buffer component 2 releases the elastic force. During the downward movement of the impact rod 1, the impact rod 1 impacts the ramming rod 602 of the ramming component 6, and the ramming force is transmitted to the ramming plate 601, so that the ramming plate 601 tamps the contact surface, thereby continuously circulating to achieve continuous ramming. In the above technical solution of the present invention, the electromagnetic loading uses primary energy, which can provide a greater impact force to the impact rod 1 while reducing energy consumption, thereby improving work efficiency. The overall structure of the device is relatively simple, and various components can be disassembled at will, which is convenient for replacement or repair. In addition, the first buffer assembly 2 and the second buffer assembly 8 can reduce the vibration generated by the impact rod 1 during high-speed cyclic impact, and can reduce the discomfort of the operator caused by recoil. Furthermore, the device can accurately control the tamping force, and the tamping force is uniform, and dust is not easy to generate.

When the impact rod 1 is subjected to impact force, these coil springs 203 can effectively absorb and disperse the impact force, reduce vibration and noise, and improve the stability and service life of the equipment, so that the tamping device is more stable during operation and reduces mechanical damage caused by impact. Furthermore, since the number and elasticity of the coil springs 203 can be adjusted according to actual needs, the buffer component has a certain adjustment flexibility. By adjusting the number and elasticity of the coil springs 203, precise control of the buffer effect can be achieved to meet the needs under different construction conditions.

[0045] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0046] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
