Description

Technical Field

[0001] The utility model belongs to the field of engineering construction, and specifically relates to an adjustable concrete vibrating device. Background Art

[0002] The smart beam yard has abandoned the traditional manual operation mode by introducing intelligent equipment. In the production process, it uses cutting-edge CNC machining technology to make steel bars, and also uses tire frames to tie steel bars. In addition, advanced construction processes and methods such as prestressed integral bundle threading, intelligent tensioning, intelligent grouting, and automatic spray maintenance are also widely used. All of this is to comprehensively improve the safety, quality and efficiency of the beam yard.

[0003] During the production of box beams in the Smart Beam Factory, we found that for small structural parts, due to the size limitation of the vibrating robot, it is impossible to perform effective concrete vibration operations. At present, this part of the work still needs to be done manually with a handheld vibrator, but this operation method requires workers to bend over for a long time, increasing their labor intensity. Therefore, we need to find a more efficient and humane way to reduce the burden on workers and improve production efficiency.

[0004] Recently, Chinese patent number CN220219025U announced a concrete vibrating device designed for the production of box beams in smart beam yards. This device cleverly combines a handle and a vibrating rod, greatly reducing the labor intensity of operators and avoiding heavy bending operations. However, the device still faces some challenges in practical application.

[0005] Since the depth of concrete may vary, the existing vibrating rod cannot be adjusted, which results in the vibrating rod being easily damaged when vibrating concrete of different depths, thus shortening its service life. In addition, the vibrating rod is often stained with concrete after vibrating, and once the concrete dries, it will seriously hinder the reuse of the vibrating rod, so it needs to be cleaned frequently.

At this time, the fixed column 5 and the slide groove 4 are in sliding motion. When the second screw rod 8 rotates, it can drive the connection block 91 to rise and fall through the threaded connection and make the connection block 91 and the limit rod 9 slide to drive the position adjustment of the connection block 91 and the vibrating rod 10. When the first screw rod 3 rotates forward and reversely to drive the fixed column 5 to move, it can drive the movement of the vibrating rod 10 and vibrate the concrete. By adjusting the height of the vibrating rod 10, it is convenient to adapt to concrete of different thicknesses and vibrate the concrete. In general, a switch 12 for the forward and reverse rotation of the first motor 11 can be set on the support frame 2.

[0044] The part of the second screw 8 that passes through the top wall of the mounting frame 7 is provided with a worm gear; two adjustment plates are provided on the top of the mounting frame 7, and a worm 14 is rotatably connected between the two adjustment plates. The worm 14 cooperates with the worm gear, and one end of the worm 14 passes through the adjustment plate and is connected to the turntable 15.

[0045] In a preferred embodiment, the mounting frame 7 is disposed above the fixing seat 6 , and the vibrating rod 10 passes through the fixing seat 6 and is slidably connected to the fixing seat 6 .

[0046] In a preferred embodiment, a limiting rod 9 is disposed in the mounting frame 7 , and two ends of the limiting rod 9 are respectively connected to the top wall of the mounting frame 7 and the fixing seat 6 .

[0047] In a preferred embodiment, there are two limiting rods 9 , which are respectively located on both sides of the second screw rod 8 .

[0048] In a preferred embodiment, a first motor 11 is installed on the top wall of the support frame 2 , and an output end of the first motor 11 is fixedly connected to the first screw rod 3 .

[0049] In a preferred embodiment, Figure 2 As shown, a handle frame 16 is fixedly connected to one side of the base 1, and a support leg is arranged below the base 1, and a moving wheel 17 is arranged at the bottom of the support leg. The arrangement of the handle frame 16 can facilitate the whole device to be moved by the moving wheel 17 through the handle frame 16.

[0050] In a preferred embodiment, a scraper (such as a rubber plate 24 ) is provided at the bottom of the fixing seat 6 , and the scraper is provided beside the vibrating rod 10 .

[0051] In a preferred embodiment, Figure 5 As shown, it also includes a drive mechanism for the scraper, which includes a rectangular frame 20, a slide plate 23 and a third screw 21; the top of the slide plate 23 is threadedly connected to the third screw 21, one end of the third screw 21 is rotatably connected to one side of the rectangular frame 20, and the other end of the third screw 21 extends out of the rectangular frame 20; the scraper is set on the slide plate 23.

[0052] In a preferred embodiment, a rotating column 22 is disposed at the end of the third screw rod 21 .

[0053] In a preferred embodiment, Figure 4 As shown, the bottom of the fixed seat 6 is rotatably connected with a gear ring 18, and the gear ring 18 is arranged outside the vibrating rod 10. The rectangular frame 20 is fixed at the bottom of the gear ring 18. The bottom of the fixed seat 6 is also rotatably connected with a gear plate 19, and the gear plate 19 is meshed with the gear ring 18; the gear ring 18 is thicker than the gear plate 19, which can ensure that the rotation of the rectangular frame 20 will not interfere with the gear plate 19. A second motor 25 is installed on the fixed seat 6, and the output end of the second motor 25 is fixedly connected with the gear plate 19. When the gear plate 19 rotates, it can mesh with the gear ring 18, thereby driving the rotation of the gear ring 18. Twisting the rotating column 22 can drive the rotation of the third screw rod 21 and make the slide plate 23 perform threaded motion with the third screw rod 21 so that the slide plate 23 can move in position within the rectangular frame 20. The movement of the slide plate 23 drives the scraper to touch the vibrating rod 10, and when the gear ring 18 rotates, it can drive the scraper to clean the vibrating rod 10.

[0054] In use, when the first motor 11 is running, its output end can drive the rotation of the first screw 3. When the first motor 11 rotates forward and reverse, the first screw 3 follows and rotates forward and reverse. When the first screw 3 rotates forward and reverse, it can drive the fixed column 5 to rise or fall through the threaded connection with the fixed column 5. At this time, the fixed column 5 and the slide 4 are in sliding motion. The turntable 15 can drive the worm 14 to rotate and make it mesh with the worm wheel 13 to drive the rotation of the worm wheel 13. Since the worm wheel 13 is fixedly connected to the second screw 8, the second screw 8 can be driven to rotate when the worm wheel 13 rotates. When the second screw 8 rotates, it can drive the connection block 91 to rise or fall through the threaded connection and make the connection block 91 and the limit rod 9 slide to drive the position adjustment of the connection block 91 and the vibrating rod 10. When the first screw 3 rotates forward and reversely and drives the fixed column 5 to move, it can drive the movement of the vibrating rod 10 and vibrate the concrete. By adjusting the vibrating rod 10, its height is adjusted, which is convenient to adapt to concrete of different thicknesses and vibrate the concrete. After the vibration is finished, the rotation column 22 can be twisted to drive the rotation of the third screw rod 21 and the slide plate 23 can be threaded with the third screw rod 21 so that the slide plate 23 can move in position within the rectangular frame 20. The movement of the slide plate 23 drives the rubber plate 24 to touch the vibrating rod 10. When the second motor 25 is running, its output end can drive the gear plate 19 to rotate, and when the gear ring 18 rotates, it can drive the rubber plate 24 to clean the vibrating rod 10. In this way, the slide plate 23 and the rubber plate 24 can rotate around the vibrating rod 10 and clean the concrete remaining on the vibrating rod 10 through the rubber plate 24, ensuring the cleanliness of the vibrating rod 10 and facilitating the next use.
