The threads at both ends of the screw rod 13 are rotated in opposite directions. The purpose of the opposite threads at both ends of the screw rod 13 is to achieve that when the screw rod 13 is rotated, the movable plates 5 and the lower frame 2 on both sides of the screw rod 13 can be close to or away from each other. Since the lower frame 2 is always located on the ground, the movable plates 5 can be lowered faster; the top end of the screw rod 13 is connected to a driving device, and the driving device is used to drive the screw rod 13 to rotate. The driving device is fixed to the top of the upper frame 1, and the driving device adopts a motor; the upper frame 1 is movably sleeved on the lower frame 2, and the top of the lower frame 2 is movably arranged The movable groove 12 is in the movable groove 12 and is threadedly connected with the screw rod 13; the bottom of the upper frame 1 is located on both sides of the movable groove 12 and is provided with auxiliary grooves 19, and the top of the lower frame 2 is provided with movable columns 16 and auxiliary columns 17, the upper end of the movable column 16 is movably arranged in the movable groove 12 of the upper frame 1, and the upper end of the auxiliary column 17 is movably arranged in the auxiliary groove 19, the screw rod 13 is threadedly connected with the movable column 16, and the lower frame 2 is movably connected with the upper frame 1 through the movable column 16, the auxiliary column 17, and the screw rod 13. Since the lower frame 2 and the upper frame 1 are movably arranged, it will cause the movable support frame as a whole to shake easily, therefore, adding the auxiliary column 17 can prevent the upper frame 1 and the lower frame 2 from shaking. The bottom of the lower frame 2 is provided with a moving wheel 11, and the moving wheel 11 adopts a universal wheel, and the vibrating device can be conveniently moved by setting the moving wheel 11.

The bottom of the mounting head 8 is fixed with a bearing, and the mounting head 8 is rotatably connected with the adjusting rod 10 through the bearing. The bearing can make the adjusting rod 10 rotate stably, and also facilitate the rotatable connection between the adjusting rod 10 and the mounting head 8. A rotating device is fixedly connected to the outer side of the mounting head 8 at one end of the movable plate 5, and the rotating device is connected to the adjusting rod 10. The rotating device includes a worm gear mechanism 20 and a motor. The worm wheel is fixedly connected to the adjusting rod 10 and the axes coincide. The worm is meshed with the worm wheel and one end of the worm is connected to the motor. The motor drives the worm to rotate, and the worm drives the worm wheel to rotate. After the worm wheel rotates, the angle of the vibrating rod 9 can be changed. The worm gear mechanism 20 has a self-locking function, which facilitates fixing the inclination angle of the vibrating rod 9.

[0036] The vibrating body 4 of the vibrator is connected to the vibrating rod 9 through a vibrating hose. The vibrating body 4 can be set on the ground or on the movable plate 5. In this embodiment, the vibrating body 4 is set on the movable plate 5, and the vibrating device can be designed as an integrated structure, which is convenient for transportation.

A plurality of mounting plates are evenly spaced and fixed on the adjusting rod 10, and a plurality of vibrating rods 9 can be installed. The mounting plate is connected with a mounting sleeve 3 by bolts, and one end of the vibrating rod 9 is set in the mounting sleeve 3. The vibrating rod 9 is connected to the adjusting rod 10 through the mounting sleeve 3. This design allows the vibrating rod 9 to be disassembled, so that it is convenient to replace the vibrator or clean and maintain the vibrating rod 9.

[0037] A clamping mechanism 21 is fixedly arranged on the outer side of the mounting head 8 at the other end of the movable plate 5, one end of the adjusting rod 10 is arranged in the clamping mechanism 21, and the clamping mechanism 21 is used to clamp the adjusting rod 10.

A T-slot 2104 is arranged at the bottom of the fixed plate 2103, and the top of the clamping arm 2101 cooperates with the T-slot 2104. The clamping arm 2101 is slidably connected to the fixed plate 2103; the clamping arm 2101 is provided with two The two clamping arms 2101 are symmetrically arranged at the bottom of the fixing plate 2103; the upper and lower sides of the clamping arms 2101 are respectively provided with connection holes, and the two clamping arms 2101 are connected by a tension screw 2105, and the tension screw 2105 passes through the connection holes on the two clamping arms 2101 in sequence; a contact plate 2102 is arranged on the side where the two clamping arms 2101 are close to each other, and the contact plate 2102 is an arc structure, and the contact plate 2102 is also provided with criss-cross anti-skid patterns. When in use, after adjusting the rotation angle of the adjusting rod 10, the clamping arms 2101 are locked by the tension screw 2105, and the two clamping arms 2101 clamp the adjusting rod 10 by the contact plate 2102 at the bottom. The criss-cross anti-skid patterns on the contact plate 2102 can increase the friction coefficient, thereby increasing the friction between the contact plate 2102 and the adjusting rod 10, and can effectively prevent the adjusting rod 10 from rotating. Through this design, the position of the adjusting rod 10 can be quickly fixed.

[0038] In actual use, the vibrating device is placed above the poured concrete, and the driving device is started. The driving device drives the screw rod 13 to rotate. Since the threads on both sides of the screw rod 13 rotate in opposite directions, the screw rod 13 rotates to make the movable plate 5 and the lower frame 2 close to each other; thereby, the vibrator is close to the concrete. After the vibrating rod 9 of the vibrator contacts the concrete, the driving device is turned off, and the telescopic device 7 is driven. After the telescopic device 7 is extended, it drives the mounting head 8 to descend, and the mounting head 8 drives the adjusting rod 10 to descend. The adjusting rod 10 drives the vibrating rod 9 to descend and insert into the concrete. The insertion depth of the vibrating rod 9 can be controlled by controlling the telescopic length of the telescopic device 7. At the same time, the rotating device is started, and the rotating device drives the adjusting rod 10 to rotate. After the adjusting rod 10 rotates, it drives the vibrating rod 9 to rotate.
