Description

Technical Field

[0001] The utility model belongs to the technical field of vibrating rods, in particular to a self-mixing and stirring vibrating rod suitable for large-volume concrete. Background Art

[0002] During the concrete construction process, the concrete needs to be vibrated to make it denser and reduce hollowing. When pouring large volumes of concrete, the concrete also needs to be poured in layers. Cold joints are easily formed at the interface of the two pourings. Therefore, vibration also takes into account the combination of the lower layer of poured concrete and the upper layer of cast-in-place concrete. Concrete vibration refers to the orderly vibration according to the length of the vibrating rod and the vibration radius. The vibrating rod usually moves about 40 cm each time. The thickness of the vibrating rod inserted into the lower layer of poured concrete is not less than 5 cm. Each vibration is done to prevent the concrete from sinking and bubbles from appearing to prevent vibration leakage or over-vibration.

[0003] When existing vibrators are used to vibrate concrete, the fluidity of the concrete will deteriorate due to insufficient moisture content or excessive dryness in the concrete, making it difficult for the concrete to flow fully during vibration, thereby increasing the friction between the vibrator and the concrete, making it difficult to pull out the vibrator. Forceful pulling may cause damage to the vibrator, especially when excessive force is applied or at an improper angle, the vibrator may be deformed or broken, thereby reducing the practicality of the vibrator.

[0032] The auxiliary component 4 includes a mounting groove 41 opened at the lower end of the vibration rod 3, and the inner side wall of the mounting groove 41 is fixedly connected to a stepper motor 42. The stepper motor 42 is a digital motor that can accurately control the movement of each step and can achieve forward and reverse rotation by changing the order of control signals. The setting of the mounting groove 41 allows the stepper motor 42 to be disassembled and assembled. The output end of the stepper motor 42 is fixedly connected to an insertion seat 421. The insertion seat 421 is rectangular, and the side wall of the insertion seat 421 is provided with a through hole 422.

[0033] A mounting base 43 is installed at the output end of the stepper motor 42. The mounting base 43 is disc-shaped. The diameter of the mounting base 43 is smaller than the diameter of the vibration rod 3. A threaded groove 431 and a slide groove 432 are provided at the lower end of the mounting base 43. The threaded groove 431 is located at the center of the mounting base 43. A connecting groove 433 is provided at one end of the mounting base 43 close to the stepper motor 42. The specification of the connecting groove 433 is compatible with the specification of the insertion seat 421. The side wall of the connecting groove 433 is threadedly connected with a fixing bolt 434. When the insertion seat 421 is fitted with the bottom wall inside the connecting groove 433, the fixing bolt 434 is docked with the position of the through hole 422. Through the cooperation between the fixing bolt 434 and the through hole 422, the insertion seat 421 can be limited.

[0034] The end of the mounting seat 43 away from the stepper motor 42 is provided with a sleeve 44 located on the outside of the vibration rod 3, the diameter of the inner wall of the sleeve 44 is larger than the diameter of the vibration rod 3, the bottom wall inside the sleeve 44 is movably connected with a ball 441, the upper end of the ball 441 is located on the inner side of the slide groove 432, the cooperation between the ball 441 and the slide groove 432 enables the sleeve 44 to rotate stably, the inner wall of the sleeve 44 is fixedly connected with a heat conducting sheet 442, the outer side of the heat conducting sheet 442 is fixedly connected with a heat conducting rod located in the side wall of the sleeve 44, the number of the heat conducting rods is several, the heat conducting sheet 442 cooperates with the heat conducting rods, and the heat generated by the vibration rod 3 and the stepper motor 42 can be transferred to the outside, so as to dissipate heat for the vibration rod 3 and the stepper motor 42;

[0035] The inner wall of the sleeve 44 is fixedly connected with a sealing gasket 443, and the sealing gasket 443 is located at the upper end of the heat conductive sheet 442. The outer wall of the sealing gasket 443 fits with the surface of the vibrating rod 3. The setting of the sealing gasket 443 can prevent water from entering the inner side of the sleeve 44, thereby damaging its stepping motor 42. The outer side of the sleeve 44 is fixedly connected with a spiral blade 45, and the lower end of the sleeve 44 is installed with a connecting seat 46.

At the same time, the rubber gasket 462 has good sealing performance, which can prevent moisture, dust and other foreign substances from entering the connection of the anti-loosening bolt 461, thereby extending the service life of the anti-loosening bolt 461.

[0036] The working principle of the above embodiment is:

[0037] When it is necessary to vibrate a large volume of concrete, first install its auxiliary component 4 on the vibrating rod 3, start the driving motor 1 through the controller, and with the cooperation of the soft shaft hose component 2, the vibrating rod 3 vibrates. At the same time, the controller controls the stepper motor 42 to rotate forward. Driven by the connecting seat 46, the connecting seat 46 drives the sleeve 44 to rotate through the anti-loosening bolt 461, and synchronously drives the spiral blade 45 on the outer side of the sleeve 44, so that the spiral blade 45 can transport the vibrated and sunken stones upward, thereby achieving the effect of homogenizing the concrete. When it is necessary to pull out the vibrating rod 3, the controller controls the stepper motor 42 to rotate in the opposite direction, so that the spiral blade 45 pushes the concrete in the opposite direction and squeezes the concrete downward, thereby driving the vibrating rod 3 to move upward.
