Description

Technical Field

[0001] This utility model relates to the field of concrete vibration technology, and in particular to a device for controlling the uniformity of concrete vibration. Background Technology

[0002] Concrete vibration is a key process in concrete pouring. Its core function is to remove air bubbles and voids inside the concrete through mechanical vibration, making the concrete denser and more uniform, thereby improving its strength, durability and appearance quality.

[0003] As disclosed in announcement number CN222847365U, a vibratory compaction device for concrete pouring in a wind turbine foundation is described. This utility model relates to the field of vibrator technology, and more particularly to a vibratory compaction device for concrete pouring in a wind turbine foundation. It includes a compaction mechanism for removing air bubbles from the concrete. The compaction mechanism includes: a main component comprising a vibrator installed inside a frame, a flexible shaft inserted into the vibrator, a vibrating rod installed at the end of the flexible shaft, and an air pump installed inside the frame; a splash-proof component comprising an external threaded sleeve fixed to the outer wall of the flexible shaft end, an internal threaded sleeve fitted onto the external threaded sleeve, a protective cover integrally formed on the outer wall of the internal threaded sleeve, a knob sleeve threaded onto the outer wall of the external threaded sleeve, and an annular air pipe on the protective cover; the vibratory compaction device for concrete pouring in a wind turbine foundation has the ability to shield concrete splashed during vibration by the vibrating rod through the protective cover; simultaneously, gas is ejected from the nozzle to blow away the splashed concrete, thereby preventing direct splashing onto the operator.

[0004] This patent avoids concrete splashing directly onto operators, but existing equipment lacks shock absorption at the bottom. During vibration, the intense vibration of the frame is transmitted to the vibrator via the flexible shaft, causing the vibrator to be inserted into the concrete in an unstable posture and uneven depth. This results in significant differences in the vibration force and duration experienced by different areas of the concrete. This poor vibration uniformity leads to residual air bubbles and uneven density distribution within the concrete, which in turn seriously affects key performance indicators such as strength, impermeability, and frost resistance. Utility Model Content

[0005] The purpose of this invention is to address the problem that existing equipment lacks vibration damping at the bottom. During vibration, the intense vibration of the frame is transmitted to the vibrator via the flexible shaft, causing instability and uneven depth of insertion into the concrete. This results in significant differences in vibration force and duration across different areas of the concrete. This poor uniformity of vibration leads to residual air bubbles and uneven density distribution within the concrete, severely impacting key performance indicators such as strength, impermeability, and frost resistance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a concrete vibration uniformity control device, comprising a vibration device body, a vibration damping adjustment component provided at the bottom of the vibration device body, the vibration damping adjustment component comprising a base, slots being provided on the front and rear surfaces of the base, bidirectional bolts being inserted into the interior of both sets of slots, threaded blocks being provided on both sides of the bidirectional bolts, a first spring being connected to the inner side of the threaded blocks, a slider being attached to the inner side of the first spring, a first rotating shaft being connected to the top of the slider, a support rod being connected to the surface of the first rotating shaft, a second rotating shaft being connected to the top of the support rod, a handle being inserted into the interior of one side of the base, a connecting rod being connected to the front end of the handle, and gears being connected to both sides of the connecting rod.

[0007] Furthermore, the connecting rod is connected to the bidirectional bolt via two sets of gears, and the bidirectional bolt is connected to the threaded block via a threaded connection.

[0008] Furthermore, the inner wall of the slider is in contact with the outer surface of the bidirectional bolt, and a sliding connection is formed between the slider and the bidirectional bolt.

[0009] Furthermore, the slider is rotatably connected to the support rod via the first rotating shaft, and the support rod is rotatably connected to the second rotating shaft.

[0010] Furthermore, dampers are connected to the four corners of the base surface, and a top plate is connected to the top of the four sets of dampers.

[0011] Furthermore, fixing blocks are connected to both sides of the base, and two sets of second springs are provided inside the fixing blocks, with top blocks connected to the tops of the two sets of second springs.

[0012] Furthermore, the outer surface of the top block is in contact with the inner wall of the fixing block, and the top block and the second spring form an elastic structure.

[0013] Furthermore, each of the four corners of the surface of the vibrating device body is connected to a disassembly assembly, which includes a sleeve, a hand-tightening bolt inserted inside the sleeve, and a limit block connected to the surface of the hand-tightening bolt.

[0014] Furthermore, threaded holes are provided at the positions where the top plate matches the four sets of hand-tightening bolts.

[0015] Furthermore, the outer surface of the limiting block is in contact with the inner wall of the sleeve, and the hand-tightening bolt passes through the sleeve and forms a threaded connection with the threaded hole.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. In this utility model, when the main body of the vibrating equipment is started, the entire equipment will vibrate. Under the influence of the vibration force, the main body of the vibrating equipment will move up and down. When the main body of the vibrating equipment is pressed down, the damper will activate the shock absorption function through the first spring and the second spring, thereby improving the uniformity of vibration and improving the key performance indicators of concrete such as strength, impermeability, and frost resistance.

[0018] 2. In this utility model, when it is necessary to disassemble the shock absorption adjustment component, the hand-tightening bolt can be rotated so that the hand-tightening bolt can be taken out from the threaded hole in the top plate, and then the shock absorption adjustment component can be directly removed, which improves the overall practicality. It simplifies the disassembly process and does not require complicated tools. Operators can quickly complete the disassembly work by manually rotating the hand-tightening bolt.

[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Example 1, such as Figure 1 - Figure 3 As shown, this utility model provides a concrete vibration uniformity control device, including a vibration device body 1. A vibration damping adjustment component 2 is provided at the bottom of the vibration device body 1. The vibration damping adjustment component 2 includes a base 201. Grooves 202 are formed on both the front and rear surfaces of the base 201. Bidirectional bolts 203 are inserted into the interior of both sets of grooves 202. Threaded blocks 204 are provided on both sides of the bidirectional bolts 203. A first spring 205 is connected to the inner side of the threaded block 204. A slider 206 is attached to the inner side of the first spring 205. A first rotating shaft 207 is connected to the top of the slider 206. A support rod 208 is connected to the surface of the first rotating shaft 207. A second rotating shaft 209 is connected to the top of the support rod 208. A handle 210 is inserted into one side of the base 201. A connecting rod 211 is connected to the front end of the handle 210. Gears 212 are connected to both sides of the connecting rod 211. 1. A meshing connection is formed between two sets of gears 212 and bidirectional bolts 203. A threaded connection is formed between bidirectional bolts 203 and threaded blocks 204. The inner wall of slider 206 is in contact with the outer surface of bidirectional bolts 203. A sliding connection is formed between slider 206 and bidirectional bolts 203. Sliding connection is formed between slider 206 and support rod 208 through a first rotating shaft 207. Rotating connection is formed between support rod 208 and second rotating shaft 209. Dampers 216 are connected to the four corners of the surface of base 201. Top plates 217 are connected to the top of the four sets of dampers 216. Fixing blocks 213 are connected to both sides of the surface of base 201. Two sets of second springs 214 are set inside the fixing blocks 213. Top blocks 215 are connected to the top of the two sets of second springs 214. The outer surface of top blocks 215 is in contact with the inner wall of fixing blocks 213. An elastic structure is formed between top blocks 215 and second springs 214.

[0029] The effect achieved in Embodiment 1 is that after the main body 1 of the vibrating device is turned on, it generates a large vibration and moves up and down through its own vibration force. When it presses downward, it drives the top plate 217 to rotate through the second rotating shaft 209 and the support rod 208, causing the other side of the support rod 208 to rotate through the first rotating shaft 207 and the slider 206, pushing the slider 206 to slide on the surface of the bidirectional bolt 203. This causes the slider 206 to press the first spring 205 through the threaded block 204. At the same time, the top block 215 presses the second spring 214 in the fixed block 213, which, together with the damper 216, reduces vibration and prevents damage. Protective function: When it is necessary to adjust the elasticity of the first spring 205, turn the handle 210 to drive the connecting rod 211 to rotate. The connecting rod 211 drives the two sets of gears 212 to rotate simultaneously, so that the two sets of gears 212 mesh with the two sets of bidirectional bolts 203 and rotate simultaneously. In turn, the two sets of bidirectional bolts 203 rotate simultaneously. When the bidirectional bolts 203 rotate, the position of the two sets of threaded blocks 204 is adjusted through the threaded connection. By rotating in both directions, the tightness of the first spring 205 can be adjusted, thereby improving the uniformity during vibration and improving the key performance indicators of concrete such as strength, impermeability, and frost resistance.

[0030] Example 2, as Figure 1 and Figure 6 As shown, disassembly and assembly components 3 are connected to the four corners of the surface of the main body 1 of the vibrating equipment. Each disassembly and assembly component 3 includes a sleeve 301. A hand-tightening bolt 302 is inserted into the inside of the sleeve 301. A limit block 303 is connected to the surface of the hand-tightening bolt 302. Threaded holes 304 are opened at the positions of the top plate 217 that match the four sets of hand-tightening bolts 302. The outer surface of the limit block 303 is in contact with the inner wall of the sleeve 301. The hand-tightening bolt 302 passes through the sleeve 301 and forms a threaded connection with the threaded hole 304.

[0031] The effect achieved in Embodiment 2 is that when the vibration damping adjustment component 2 needs to be disassembled, the operator only needs to manually turn the hand-tightening bolt 302. Since the hand-tightening bolt 302 is threadedly connected to the threaded hole 304 on the top plate 217, it will gradually unscrew from the threaded hole 304 as the hand-tightening bolt 302 is turned. During this process, the limiting block 303 fits tightly against the inner wall of the sleeve 301, which limits the range of movement of the hand-tightening bolt 302, ensuring that it will not shift or shake during disassembly, thus ensuring the stability and accuracy of the disassembly operation. When the hand-tightening bolt 302 is completely removed from the threaded hole 304, the connection constraint between the vibration damping adjustment component 2 and the vibrating equipment body 1 is released, and the operator can then directly remove the vibration damping adjustment component 2.

[0032] Working principle: When the main body 1 of the vibrating equipment is started, the entire equipment will vibrate. Under the influence of the vibration force, the main body 1 of the vibrating equipment will move up and down. When the main body 1 of the vibrating equipment is pressed down, the damper 216 will activate the shock absorption through the first spring 205 and the second spring 214, thereby improving the uniformity of vibration and improving the key performance indicators of concrete such as strength, impermeability, and frost resistance. When it is necessary to disassemble the shock absorption adjustment component 2, the hand-tightening bolt 302 can be turned so that the hand-tightening bolt 302 can be removed from the threaded hole 304 of the top plate 217. Then the shock absorption adjustment component 2 can be removed directly, which improves the overall practicality. It simplifies the disassembly process and does not require complicated tools. The operator can quickly complete the disassembly work by manually turning the hand-tightening bolt 302.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
