The embodiment of the utility model provides a bidirectional vibroflotation device, which comprises a shell 1, a shaft sleeve 2, a main shaft 3, a power mechanism 31, a first rotating shaft 41 and a first transmission device, wherein the shell 1 mainly plays roles of bearing and transmitting excitation, and one end of the shell 1 is provided with a vibroflotation head 14; the shaft sleeve 2 is rotatably arranged in the shell 1, and the shaft sleeve 2 is provided with a first eccentric block 21; the main shaft 3 is rotatably arranged in the shaft sleeve 2, the main shaft 3 can be connected with or separated from the shaft sleeve 2, the main shaft 3 is connected with the power mechanism 31, and the power mechanism 31 is used for driving the main shaft 3 to rotate; the first rotating shaft 41 is rotatably arranged in the shell 1, the axis of the first rotating shaft 41 is perpendicular to the axis of the main shaft 3, and the first rotating shaft 41 is provided with a second eccentric block 411; the first transmission device is connected between the main shaft 3 and the first rotating shaft 41, and is used for converting the rotation of the main shaft 3 into the rotation of the first rotating shaft 41, the input end of the first transmission device is connected or separated with the main shaft 3, and the output end of the first transmission device is connected with the first rotating shaft 41.
Since the spindle 3 is connectable or disconnectable to the sleeve 2 and the spindle 3 is connectable or disconnectable to the input of the first transmission, the present embodiment enables different movement patterns by connecting the spindle 3 to the sleeve 2 and/or to the input of the first transmission.
When the spindle 3 is connected with the shaft sleeve 2 and separated from the input end of the first transmission device, the power mechanism 31 drives the spindle 3 to rotate, so that the spindle 3 drives the shaft sleeve 2 to rotate together, and because the shaft sleeve 2 is provided with the first eccentric block 21, vibration excitation perpendicular to the axis direction of the shaft sleeve 2 can be generated, for example, when the spindle 3 and the shaft sleeve 2 are vertically arranged, horizontal vibration excitation can be generated when the spindle 3 drives the shaft sleeve 2 to rotate together. This excitation mode is suitable for softer strata, for example, when the bidirectional vibroflotator is used for vibroflotation and hole forming, the spindle 3 is connected with the shaft sleeve 2, and the mode of horizontal excitation is adopted for hole forming of the generally softer strata.
When the spindle 3 is separated from the shaft sleeve 2 and connected with the input end of the first transmission device, the power mechanism 31 drives the spindle 3 to rotate, so that the spindle 3 drives the first rotating shaft 41 to rotate together through the first transmission device, and because the axis of the first rotating shaft 41 is perpendicular to the axis of the spindle 3 and the first rotating shaft 41 is provided with the second eccentric block 411, excitation perpendicular to the axis direction of the first rotating shaft 41 can be generated, that is, excitation is generated along the axis directions of the spindle 3 and the shaft sleeve 2, for example, when the spindle 3 and the shaft sleeve 2 are vertically arranged, the first rotating shaft 41 is horizontally arranged, and when the spindle 3 drives the first rotating shaft 41 to rotate together through the first transmission device, vertical excitation can be generated. This excitation mode is more suitable for harder formations, for example, when harder formations are encountered, the bi-directional vibroflotation device is difficult to hole downwards or slow in footage, and holes can be formed by connecting the main shaft 3 with the input end of the first transmission device instead of using a vertical excitation mode.
When the main shaft 3 is connected with the shaft sleeve 2 and the input end of the first transmission device, the power mechanism 31 drives the main shaft 3 to rotate, so that the main shaft 3 drives the shaft sleeve 2 to rotate together, and the main shaft 3 drives the first rotating shaft 41 to rotate together through the first transmission device, namely, the main shaft 3, the shaft sleeve 2 and the first rotating shaft 41 rotate together, and when the shaft sleeve 2 rotates, excitation perpendicular to the axial direction of the shaft sleeve 2 is generated; when the first rotating shaft 41 rotates, excitation perpendicular to the axial direction of the first rotating shaft 41 (that is, excitation along the axial directions of the spindle 3 and the sleeve 2) is generated; that is, the bi-directional vibroflotation device can generate vibration in the directions perpendicular to each other, for example, horizontal vibration and vertical vibration are generated at the same time, and in the process of using the bi-directional vibroflotation device to perform vibroflotation hole forming and vibration compaction broken stone filling, the main shaft 3 is connected with the shaft sleeve 2, the main shaft 3 is connected with the input end of the first transmission device, and horizontal vibration force and vertical vibration force are generated at the same time, and meanwhile, bi-directional vibration compaction operation is performed, so that the construction efficiency and the pile forming quality are improved.
Therefore, the bidirectional vibroflotation device provided by the embodiment can respectively control and select the exciting forces (such as horizontal exciting force and vertical exciting force) in two directions which are vertical to each other, and can realize the combination of the exciting forces in two directions which are vertical to each other (such as the same time for generating the horizontal exciting force and the vertical exciting force), so that the bidirectional vibroflotation device is flexible and flexible, has strong adaptability, can adapt to various soft and hard geological conditions, and realizes the highest-efficiency construction and optimal quality piling. For example: when encountering a softer stratum section, a horizontal excitation mode is adopted, so that compaction of the soil layer and the hole wall is facilitated; when encountering a harder solid stratum section, a vertical excitation mode is adopted, so that the method is more beneficial to rapidly penetrating through a hard stratum, and high-efficiency pore-forming is realized; when the pore-forming is completed and the pile-forming stage of the section-by-section filling is carried out, the complex excitation force which acts in the horizontal and vertical directions simultaneously is adopted, so that the high-efficiency vibration compaction of the pile body is facilitated, and the pile body with better quality is formed.
