Description

Technical Field

[0001] The utility model relates to the technical field of concrete compaction, in particular to a flat plate vibrating machine used for concrete compaction. Background Art

[0002] In order to ensure that the concrete can achieve the ideal compaction effect under different thickness conditions, the vibration amplitude of the plate vibrator needs to be flexibly adjusted according to the specific situation. Thinner concrete layers require smaller vibration amplitudes to avoid excessive vibration leading to concrete delamination or surface cracks; while thicker concrete layers require larger vibration amplitudes so that the vibration energy can be fully transmitted to the deep layer, eliminating internal voids and improving the integrity and bearing capacity of the concrete.

[0003] The existing vibration machine adjusts the amplitude by changing the angle between the counterweights on both sides. Once there is an error in the angle of the counterweights on both sides, the balance of the vibration machine will be broken, causing the vibration machine to produce abnormal vibration and stress during operation. Long-term operation in this unbalanced state will bring excessive load and stress to the vibration motor, thereby causing wear, deformation and even damage to the internal components of the motor. Therefore, there is a problem of inconvenience in adjusting the amplitude of the vibration machine. Utility Model Content

[0024] In order to facilitate the adjustment of the vibration amplitude of the vibration motor 205, the other end of the shock-absorbing spring 307 is fixedly connected to the inner wall of the fixed frame 306, and the inner wall of the fixed frame 306 is fixedly connected with a damper 308. The other end of the damper 308 is fixedly connected to the lower surface of the sliding base 310. The shock-absorbing spring 307 and the damper 308 facilitate the vibration reduction of the sliding base 310. The upper surface of the sliding base 310 is hinged with a rotating plate 301, and the outer surface of the rotating plate 301 is fixedly connected to the limiting frame 302. The inner wall of the frame 302 is slidably connected with a telescopic rod 303. The direction of the telescopic rod 303 can be adjusted by rotating the plate 301 to facilitate adaptation to people of different heights. The outer surface of the telescopic rod 303 is provided with multiple sets of limit bolts 305. The outer surface of the limit bolts 305 is threadedly connected with the limit bolts 305. The limit bolts 305 are threadedly connected to the outer surface of the limit frame 302. The telescopic rod 303 can be positioned by rotating the limit frame 302 to prevent the telescopic rod 303 and the limit frame 302 from separating.

[0025] It is worth mentioning that by rotating the mounting bolt 203, it is convenient to disassemble the counterweight block 202 and the locking ring 204, to increase or decrease the weight of the counterweight block 202, and to adjust the vibration amplitude of the vibration motor 205. The weight of the counterweight blocks 202 on both sides of the vibration motor 205 can be adjusted according to the thickness of the concrete, so that the number of counterweight blocks 202 on both sides of the vibration motor 205 is equal, and the vibration amplitude of the vibration motor 205 can be adjusted, which has the function of convenient adjustment.

[0026] In order to facilitate the adjustment of the length of the telescopic rod 303, the outer surface of the output shaft 201 is slidably connected to multiple groups of counterweight blocks 202, the upper surface of the counterweight block 202 is affixed with a locking ring 204, and the outer surface of the locking ring 204 is threadedly connected with a mounting bolt 203. By rotating the mounting bolt 203, the counterweight block 202 and the locking ring 204 can be easily disassembled, thereby facilitating the increase or decrease of the weight of the counterweight block 202. The other end of the mounting bolt 203 is threadedly connected to the outer surface of the counterweight block 202, and the outer surface of the locking ring 204 is provided with a groove. The groove provided on the outer surface of the locking ring 204 facilitates the adjustment of the distance between the counterweight blocks 202.

[0027] It is worth mentioning that by rotating the limit bolt 305, the limit bolt 305 and the telescopic rod 303 are separated, and then the telescopic rod 303 is moved to slide on the inner wall of the limit frame 302, so as to facilitate the adjustment of the length of the telescopic rod 303. When adjusted to a suitable position, the limit bolt 305 is rotated to make it threadedly connected with the threaded hole 304, so as to facilitate the positioning of the telescopic rod 303 and to facilitate the adjustment of the angle of the telescopic rod 303.

[0028] Working principle: By rotating the mounting bolt 203, it is convenient to disassemble the counterweight block 202 and the locking ring 204, to increase or decrease the weight of the counterweight block 202, and to adjust the vibration amplitude of the vibration motor 205. The weight of the counterweight blocks 202 on both sides of the vibration motor 205 can be adjusted according to the thickness of the concrete, so that the number of counterweight blocks 202 on both sides of the vibration motor 205 is equal, and the vibration amplitude of the vibration motor 205 can be adjusted. It has a convenient adjustment function. By rotating the limit bolt 305, the limit bolt 305 and the telescopic rod 303 are separated, and then the telescopic rod 303 is moved to slide on the inner wall of the limit frame 302, so as to facilitate the adjustment of the length of the telescopic rod 303. After adjusting it to a suitable position, the limit bolt 305 is rotated to make it It is threadedly connected to the threaded hole 304, which is convenient for positioning the telescopic rod 303. Then, the telescopic rod 303 is held in the hand, and the vibration motor 205 is started. The vibration motor 205 drives the counterweight blocks 202 and the locking ring 204 on both sides to rotate synchronously, thereby making the protective cover 206, the vibration plate 1 and the fixed frame 306 vibrate, which is convenient for vibrating the concrete. Since the user's hands hold the outer surface of the telescopic rod 303, it is convenient to limit the sliding base 310. When the fixed frame 306 vibrates following the vibration plate 1, the sliding base 310 slides on the inner wall of the fixed frame 306. The damper 308 and the baffle 309 can reduce the vibration of the rotating plate 301, thereby improving the user's comfort to a certain extent.
