DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0031] With reference to Figure 1 , Figure 2 and Figure 3 , the utility model provides an embodiment: a kind of super-long concrete structure construction anti-cracking vibrator, including vibration machine 1, the top of the outer wall of vibration machine 1 is fixedly connected with starter 3, the output end of vibration machine 1 is fixedly connected with vibration tube 4, the outer wall middle part of vibration tube 4 is provided with fixed ring 5, the top of fixed ring 5 is provided with recess 6 in front and back sides, the inner wall left and right sides of two recesses 6 are fixedly connected with a plurality of springs one 7, the adjacent side of a plurality of springs one 7 is slidably connected with moving block 8, the outer wall top of a plurality of moving blocks 8 is fixedly connected with handle 9, the outer wall of fixed ring 5 is provided with adjusting mechanism 2, adjusting mechanism 2 is used to adjust different positions;

[0032] Specifically, the starter 3 of the outer wall top of vibration machine 1 is used to open equipment, and the output end is firmly connected with vibration tube 4, the top of the fixed ring 5 of the outer wall middle part of vibration tube 4 is opened with recess 6 in front and back sides, a plurality of springs one 7 in the inner wall left and right sides of recess 6 are slidably connected with moving block 8, handle 9 is fixed on the top of moving block 8, when working, starter 3 is opened, vibration machine 1 operates to generate vibration and is transmitted to vibration tube 4, so that vibration tube 4 vibrates and acts on concrete, the operator holds handle 9, due to the elasticity of spring one 7, moving block 8 can be flexibly adjusted in position in recess 6 according to the force exerted by the operator, which not only facilitates the operator to control the position and direction of vibration tube 4 according to the construction requirement, and accurately applies vibration to each part of super-long concrete structure, but also can reduce the impact force of vibration on hand by the buffering action of spring one 7, thereby effectively improving the anti-cracking effect during super-long concrete structure construction and guaranteeing construction quality.

[0033] With reference to Figure 2 and Figure 4 , adjusting mechanism 2 includes two connecting plates 201, the rear side of the outer wall of two connecting plates 201 is fixedly connected on the front side upper and lower end of fixed ring 5, the adjacent side of two connecting plates 201 is uniformly fixedly connected with spring two 202, the left side of top connecting plate 201 is threadedly connected with bolt 203, the left side of bottom connecting plate 201 is fixedly connected with nut 204, bolt 203 is threadedly connected with nut 204;

[0034] Specifically, when the worker manually tightens the bolt 203, its rotational motion is converted into linear motion due to the threaded fit, changing the extension length in the nut 204. The spring 202 deforms as the bolt 203 is tightened. When the bolt 203 is tightened outward, it stretches the spring 202, and the elastic force causes the fixing ring 5 to tend to move upward. When it is tightened inward, it compresses the spring 202, causing the fixing ring 5 to tend to move downward. By precisely controlling the number of turns and the force of the bolt 203, the worker can fine-tune the position of the fixing ring 5 on the vibrating tube 4, thereby flexibly adjusting the angle and height of the vibrating tube 4 to adapt to various construction locations and working conditions. This ensures that the vibrator exerts optimal anti-cracking vibration performance at key points of ultra-long concrete structures, stabilizes the construction quality and stability of concrete structures, and improves the overall construction effect and project quality.

[0035] Reference Figure 2 , Figure 3 and Figure 5 Vibrating tube 4 has a vibrating plate 10 fixedly connected to the left side of its outer wall. Multiple fixing blocks are fixedly connected to the four sides of the left side of the vibrating plate 10. A connecting groove 12 is opened on the left side of the outer wall of the starter 3. A handle 13 is fixedly connected to the inner wall of the connecting groove 12. A connecting wire 14 is fixedly connected to the right side of the outer wall of the starter 3. A plug 15 is fixedly connected to the other end of the connecting wire 14.

[0036] Specifically, when the vibrator 1 is started, the generated vibration is transmitted to the vibrating tube 4 through the output end, and the vibrating tube 4 then begins to vibrate. Since the vibrating plate 10 is fixedly connected to the left end of the outer wall of the vibrating tube 4, the vibrating plate 10 vibrates together with the vibrating tube 4, and its vibration frequency and amplitude are consistent with the vibrating tube 4. The multiple fixing blocks fixedly connected around the outer wall of the vibrating plate 10 increase the structural strength of the vibrating plate 10. The starter 3, as the key component for controlling the start and stop of the vibrator 1, has a handle 13 fixedly connected in the connection slot 12 on the left side of its outer wall, which facilitates the carrying and moving of the entire vibrator equipment by the staff. The connecting wire 14 and plug 15 fixedly connected to the right side of the outer wall of the starter 3 are important parts for providing power support to the vibrator 1. When the plug 15 is inserted into a suitable power socket, the current is transmitted to the starter 3 through the connecting wire 14. The starter 3 uses its internal circuit control system to convert electrical energy into control signals, thereby starting the vibrator 1.

[0037] Reference Figure 2 , Figure 3 and Figure 4 The top of the starter 3 is fixedly connected to a fixing block 16, and the top of the fixing block 16 is fixedly connected to a temperature controller 17; the bottom of the outer wall of the vibrator 1 is provided with a connecting seat 18, the top of the connecting seat 18 is provided with a connecting groove 19, and the vibrator 1 is fixedly connected to the connecting groove 19; the bottom of the connecting seat 18 is provided with an installation groove 20, and the inner wall of the installation groove 20 is fixedly connected to a shock absorber 21.

[0038] Specifically, when the vibrator starts working, the vibrator 1 generates vibration and heat. The temperature controller 17 on the top of the starter 3 is fixedly installed by the fixing block 16, which can monitor the temperature changes of the vibrator 1 and the surrounding environment in real time. The vibrator 1 is fixedly connected to the bottom of the outer wall and the top of the connecting seat 18 by the connecting groove 19. This connection method ensures the stability of the vibrator 1 during operation, enabling it to effectively transmit vibration energy. The damping plate 21 fixedly connected in the mounting groove 20 at the bottom of the connecting seat 18 plays a key buffering role. When the vibrator 1 generates vibration, the damping plate 21 can absorb and disperse the vibration energy, reducing the transmission of vibration to the surrounding environment and supporting structure.

[0039] Working principle: After the vibrator 1 is turned on, its internal power device starts to operate, generating high-frequency vibration. This vibration is directly transmitted to the vibrating tube 4 through the output end of the vibrator 1, causing the vibrating tube 4 to vibrate violently. The fixing ring 5 in the middle of the outer wall of the vibrating tube 4 serves as a connecting and supporting component. Multiple springs 7 in the groove 6 at the top of the ring are in this vibration environment. Due to the elasticity of the springs 7, they will sway under the action of the vibration wave. When the springs 7 sway, the moving blocks 8 will be forced to make corresponding displacement changes within a limited range. The handles 9 are fixedly connected to the top of the outer wall of the multiple moving blocks 8. When the moving blocks 8 make such small displacement changes, it is equivalent to having a buffer transition mechanism between the handles 9 and the vibrating tube 4.

[0040] Furthermore, when the position of the vibrating tube 4 needs to be adjusted, the operator manually tightens the bolt 203 on the left side of the top connecting plate 201. Since the bolt 203 is threadedly connected to the nut 204 on the left side of the bottom connecting plate 201, the rotational motion of the bolt 203 is converted into linear motion, thereby changing its extension length in the nut 204. During this process, the springs 202 on the adjacent sides of the two connecting plates 201 will deform as the bolt 203 is tightened. When the bolt 203 is tightened outward, a pulling force is applied to the spring 202, and the spring 202 is stretched. The elastic force generated by the spring acts on the fixing ring 5, causing the fixing ring 5 to have an upward displacement tendency. When the bolt 203 is tightened inward, the spring 202 is compressed, and the elastic force causes the fixing ring 5 to have a downward displacement tendency.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
