Description

Novel vibroflotation main body structure Technical Field The utility model belongs to the technical field of foundation treatment equipment, and particularly relates to a novel vibroflotation main body structure. Background The vibroflotation method is a construction method commonly used for foundation reinforcement and foundation improvement, and the basic principle is that a vibroflotation device is inserted into the foundation, soil is loosened and compacted through high-speed vibration, and materials are added into holes in a matching manner when necessary to improve the strength and stability of the foundation. In vibroflotation equipment, a vibroflotation main body is used as a core execution component, and the structural design of the vibroflotation main body directly influences the vibration efficiency, the stability and the service life of the equipment. At present, a common vibrator main body structure generally adopts a mode of a single main shaft and eccentric blocks, and bearings are arranged at two ends of the main shaft and used for supporting the high-speed rotation of the main shaft of the eccentric blocks. However, in the actual construction process, the structure has the defects that on one hand, the main shaft is easy to generate larger bending deformation when being stressed during operation, particularly during pile-making operation in a deep foundation, so that uneven stress and accelerated abrasion of the bearing are caused, and on the other hand, stress points of the vibrating shell in the existing structure are concentrated and can not effectively disperse load, so that the local part of the shell is easy to damage, and the durability and the running stability of the integral structure are influenced. In addition, the main shaft depends on single-ended transmission, the synchronization performance is poor, the condition that the upper main shaft and the lower main shaft rotate out of synchronization easily occurs, and the vibration punching efficiency is further reduced. Disclosure of utility model Aiming at the problems existing in the prior art, the utility model aims to provide a novel vibroflotation main body structure which can be realized by a reasonable bearing arrangement mode and a double-spindle linkage structure, so that the supporting strength of a spindle is enhanced, the bending degree of the spindle is reduced, the bearing wear rate is reduced, and meanwhile, the stress points of a vibrating shell are dispersed, thereby prolonging the service life of the whole equipment and improving the vibroflotation operation effect. In order to achieve the above purpose, the present utility model provides the following technical solutions: The novel vibroflotation main body structure comprises a shell, wherein a main shaft is arranged in the shell, and bearings are sleeved at two ends of the main shaft; An eccentric block is sleeved at the middle part of the main shaft; the number of the main shafts is two, and a connecting component is arranged between the two main shafts and used for connecting the two main shafts together; the connecting assembly comprises a splicing column spliced at one end of the main shaft, and a splicing ring is sleeved on the splicing column. Furthermore, the two ends of the main shaft are fixedly connected with bearing seats, and the bearing sleeves are arranged on the bearing seats. Furthermore, one end of the bearing seat is provided with a splicing groove which is arranged into a regular polygon; The plug-in post is inserted into the plug-in groove. Furthermore, the upper end face of the splicing ring is provided with a through groove in a penetrating mode, and the splicing ring is located between the two main shafts. Further, splicing grooves are formed in the upper end face of the bearing seat at equal intervals around the central axis of the bearing seat; The top and the bottom of concatenation ring all fixedly connected with splice strip. Further, the clamping groove is formed in one end of the splicing strip, and the clamping groove is clamped at the corner of the splicing column. Compared with the prior art, the utility model has the beneficial effects that: The structure can effectively reduce the rotation hysteresis problem of the lower spindle caused by no independent power source, improve the vibration synchronism, thereby improving the vibration punching efficiency and enhancing the transmission stability of the vibration force in the axial range of the whole vibrator. The structure can effectively limit the bending deformation of the main shaft in the high-speed rotation process and reduce the axial float, thereby reducing the wear rate of the bearing, prolonging the service life and improving the problem of concentrated stress of the vibrating shell caused by the bending of the main shaft compared with the single-side bearing supporting mode in the prior art. The bearing seat and the connecting component are connected in a positioning wa
